Tablet Battery Capacity Is 6 4

Charging the device for the first time after purchase

However, in order for the battery to function fully, after purchasing the new iPhone 6, you need to properly charge it. According to experts, the first time the device should be charged to the maximum, that is, to the full. To do this, the phone needs to be completely “will plant”. After that, it must be connected to the network and wait until charging is completed. After that, your iPhone can be used normally. In the future, by the way, the procedure needs to be carried out partially, that is, for example, if the battery shows 50% charge or even 90%. It doesn’t matter. In general, the iPhone 6 battery (as well as the Plus version) is better suited for this type of charge.

Iphone 6: battery capacity. IPhone 6 Battery Prices

In the fall of 2014, a new generation of the legendary Apple phone was released. Iphone 6. Together with him came his “brother”. The 6 Plus model, which, in fact, simply has an increased body size (hence, also a screen with a battery). As for the latter, while the iPhone 6 has a battery capacity of 1810 mAh, the Plus model has a 2915 mAh battery. Thus, the life of the second device is slightly longer, although the energy consumption is much higher here.

It is interesting that each of those who purchased this device lists its different advantages. Fans note the smooth operation of the device, the stylish design, the special status that the iPhone 6 gives to its owner, and a long period of activity without recharging. In the last paragraph. Apple’s phone consumption. We will talk in this article.

How to charge iPhone 6 faster

So, we all know the moments when we need to charge the smartphone, but there is no time for this due to certain circumstances. So, there is a theory that in order to speed up the process of charging the battery on the iPhone 6 (battery capacity is not important. It can also be an iPhone 4 or 5 generation battery), you just need to turn on the mode “In the airplane”. As a result, a number of functions that consume power (Wi-Fi, 3G, Bluetooth, network signal reception) are disabled in the smartphone, and the process really accelerates.

How to extend battery life

In addition, the iPhone 6’s lithium-ion battery cannot often be “scratch”. This type of battery is not designed for frequent full power consumption, so they work best in a constant recharge mode, and not power supply from 0%.

In addition, you should adhere to other recommendations for battery use. True, they are more obvious. So, you should protect it from mechanical damage, from moisture and dirt, and so on. These recommendations are elementary, and most users follow them regularly.

IPhone Battery Replacement

If the battery capacity of the iPhone 6 Plus, due to the age of the device, as well as due to some damage or malfunction, does not suit you to a significant extent, you may think about replacing the battery on the iPhone. However, you shouldn’t do it yourself. We recommend purchasing the battery separately (since this will save you money) and taking it along with the phone to a specialized service center. There, experts will professionally service your smartphone, replace it.

How to choose a new battery?

Taking a look at the labeling of any modern battery, be it a lithium-ion cell phone battery or a lead-acid battery from an uninterruptible power supply. We can always find information there Not only in the nominal voltage of this power source, but also in its electrical capacity.

Usually these are numbers like 2200 mAh (read as 2200 milliampere-hours), 4Ah (4 ampere-hours), etc. As you can see, a non-system unit of measurement is used to measure the battery capacity. Ah (Ampere hour). “Ampere hour”, and not at all “farad “as for capacitors. And the clock appears here for a reason, but for the reason that a conventional battery, unlike a conventional capacitor, is able to power the load literally for hours.

If we try to explain it quite simply, then the capacity of the battery in ampere-hours is a numerical expression of how long a given battery can supply a load with a certain current consumption.

For example, if a battery with a nominal voltage of 12 volts is fully charged, while it has a capacity of 4 Ah, this means that a load with a current consumption of 0.4 amperes, with a nominal voltage of 12 volts, this battery will be able to supply for 10 hours until a condition occurs in which further discharge would become hazardous to performance. And through a load with a current consumption of 1 ampere, the same battery will be discharged for 4 hours (theoretically, of course).

Of course, for each battery there is a limitation on the maximum allowable discharge current, and the higher the discharge current, the lower the linearity of the discharge characteristic will be, and the faster the battery will drain in comparison with the estimated time.

The minimum allowable voltage at which the battery can be discharged is also regulated and always indicated in the documentation for a specific battery, as well as the maximum safe voltage, above which it is very NOT desirable to charge the battery.

For example, typical for a 3.7 volt lithium-ion battery, the maximum permissible minimum discharge voltage is 2.75 volts, and the maximum is 4.25 volts. If the lithium battery is discharged to less than 2.75 volts, then the battery will begin to lose capacity, and if overcharged excessively, it may explode.

For a 12 volt lead acid battery, the safety minimum is 9.6 volts, and the maximum you can charge to is 13 volts, etc.

As you can see, volts are NOT mentioned at all in the information about the capacity (in ampere-hours). Meanwhile, if we convert the hours into seconds, and then multiply the capacity value by the battery voltage, we get the value of the charge energy of the given battery in joules:

One way or another, the capacity of a properly functioning battery practically does NOT depend on the voltage at its terminals at the current moment. But when we say “battery charge”, we mean NOT the capacity, but just the voltage at which the battery is now charged. If the battery is charged to the rated voltage, then you can count on the capacity that the battery has at that moment. If the battery is DISCHARGED, then its capacity does not matter anymore.

In this case, the real capacity of the battery, as can be seen from the family of discharge characteristics, strongly depends on the magnitude of the discharge current. A 10 hour discharge and a 10 minute discharge, for example for a lead acid battery (see picture above), will show a difference in capacity of approximately half!

You can even find a more or less accurate mathematical relationship between the discharge current and the discharge time of a particular battery instance. This dependence was revealed by the German scientist Peikert, and VEL the so-called “Peikert coefficient” g, which, for example, for sealed lead-acid batteries is in the region of 1.25. The higher the discharge current, the shorter the discharge time. And the constant on the right side of the equation. it directly depends on the nominal capacity of the battery.

If desired, the real capacity of the battery can be determined very simply: it will fully charge the battery (to the maximum allowed voltage, which is indicated in the documentation), and then discharge with a constant current (close to the 10-hour characteristic from the documentation) to the final discharge voltage (which is also given in documentation). Multiply the discharge current and discharge time in hours. you get the real battery capacity in ampere or milliampere-hours.

Earlier, ElectroVesty wrote that with the Climate Change Storage (CCT Energy Storage) tartap from South Australia, he built and launched the world’s first thermal battery, which can store six times more energy than a lithium battery of similar capacity. In addition, the cost of the thermal accumulator is 20-40% cheaper.

Battery specifications for all iPhone models.

tablet, battery, capacity

Not all smartphone selection criteria are the same. Someone needs a high-quality camera, someone cares more about the power of the processor, and the third, if only the autonomous operation of the device is at its best. We decided to bring together information about the battery capacities of all iPhone models, so that when choosing a smartphone for potential buyers, there would be no questions.

Iphone SE

The iPhone SE is the perfect copy of the iPhone 5s in appearance. But the battery in the iPhone SE has a higher capacity than that of the “big brother”. The difference cannot be called significant, but the battery life of the iPhone SE is still higher compared to the iPhone 5s.

Battery: Built-in 1624mAh Li-ion battery.

Iphone XS

The direct successor to the iPhone X, the 5.8-inch iPhone XS, surprised by the size of its battery, which turned out to be less than its predecessor. However, it’s important to note here that the battery life of the iPhone XS has increased. The smartphone lasts 30 minutes longer than the iPhone X. All thanks to the more energy efficient A12 Bionic processor.

Video review of the tablet Samsung Galaxy Tab S 10.5. Interface

Just like the younger brother in the family, Samsung Galaxy Tab S 10.5 runs on Android 4.4. “KitKat”, complemented by the proprietary Samsung TouchWiz shell and a number of additional features. Recall that one of the most interesting features of Multi Window is that you can work with two different applications at the same time, for example, call the second one and view the news.

It is impossible not to mention the SideSync 3.0 service, which allows you to combine your tablet with an Android smartphone for two-way data exchange. Samsung KNOX allows you to protect content and software, the Remote PC app will help you get remote access to your home or office PC, and “Children” will surely be appreciated by parents who are NOT afraid to share their tablet with young children. The proprietary S Voice system will be able to perform tasks using voice commands, and S Planner will help you optimally plan your work day. Even the length and breadth of the familiar Samsung Galaxy Tab S 10.5 desktop contains Not only application shortcuts, widgets and the system notification bar, but also a file manager call button, as well as a drop-down toolbar for quick access to five favorite applications. I wonder what to bring into this drop-down panel You can not only system, but also any other installed applications.

Comparison of the Android and iOS operating systems deserves a separate voluminous material, but even it will not give an unambiguous answer to the question. which of the two systems is more beautiful, convenient and functional. over, mobile operating systems do not stand still and each of them is gradually acquiring the features of its rival.

The fingerprint scanner

The fingerprint scanner still looks more like a toy for geeks than a serious tool for solving real problems. And nevertheless, already now, using your fingerprint, you can not only unlock a password-protected tablet, but, for example, it is convenient to pay for a purchase in the PayPal system.

To start working with the identification system, you need to gently slide your fingertip down the Home key eight times in a row. In total, up to three fingerprints can be registered in the database, that is, verification capabilities can be used not only by the tablet owner, but also by his family members.

Together with the fingerprint, you must specify an additional alphanumeric password, which will help you log into the system in case of problems. After five unsuccessful attempts, the Samsung Galaxy Tab S 10.5 will close the ability to log in fingerprints for 30 seconds, and after a dozen errors in a row, the tablet can only be unlocked using the same alternative password. If fingerprint detection is unsuccessful, the system will display prompts with the premise of an error. loose finger pressure, too fast scanning, wet hands, etc.

At the moment, the Apple iPad Air cannot boast of a fingerprint scanner, but judging by the presence of this unit in the iPhone 5S / 6/6 Plus smartphones, its appearance can be expected in the second generation of the apple tablet.

Super AMOLED display

The Samsung Galaxy Tab S 10.5 is equipped with a 10.5-inch Super AMOLED display with a resolution of 2560 × 1600 pixels, which corresponds to a pixel density of 287 PPI. The absence of the Plus prefix in the name of the matrix indicates that the subpixels are arranged according to the usual PenTile scheme for AMOLED matrices, but the size of a single point in this screen is so small that it is almost impossible to see the unpleasant features of this technology. The viewing angles of the Super AMOLED screen are at a very decent level, artifacts in the form of a green tint on a white background can be seen only from an acute viewing angle.

According to Samsung, their Super AMOLED matrix displays up to 94% of the natural color gamut of Adobe RGB (CIE 1931 color space), while most TFT models reproduce about 73% correctly. What is even more impressive is the deep black color, which is provided by the complete absence of glow, and not by dimming the backlight, as in TFT-screens. As a result, the contrast ratio of the Samsung Galaxy Tab S 10.5 is an impressive 100,000: 1, which is 100 times higher than a typical TFT result. Capacitive touchscreen supports up to 10 simultaneous touches, while the settings can further increase its sensitivity for use with gloves.

The measured brightness of the screen ranged from 2 cd / m2 to 280 cd / m2, both manual adjustment and automatic adjustment to ambient light conditions are available based on the light sensor shown. In the settings, you can also find a special auto-adjustment of the screen brightness depending on the display mode, which is designed to save battery power. Helps extend autonomy and technology “Smart shutdown”, which tracks your face with the front camera and will automatically turn off the backlight as soon as you stop looking at the screen.

Depending on personal preference, you can choose the following display modes: “Premium cinema”, “Professional photography” and “Regular cinema”. The first mode clearly demonstrates all the advantages of the Samsung Galaxy Tab S 10.5 AMOLED matrix. the picture is clear and bright, “Regular cinema” makes the image warmer, but in the mode “Professional photography” the screen displays the most naturalistic picture with natural color gamut. In addition to the above modes, you can select two more options in the settings: a checkmark opposite the item “Optimize display” will adjust the color range, saturation and sharpness to achieve the Best result in Gallery Camera, Browser, Video, Books applications. Well, the reading mode will adjust all screen parameters in selected applications in such a way that the user is most comfortable to perceive the text.

Recall that Apple iPad Air is equipped with a 9.7-inch IPS-matrix with a resolution of 2048 by 1536 pixels and a dot density of 264 PPI. As you can see, Samsung Galaxy Tab S 10.5 wins here in all respects. diagonal, resolution and density. Interestingly, at first glance, the difference in pixel density does NOT look impressive, but in fact, more than a million points fit in the gap between 287 PPI and 264 PPI (4096000 in Samsung Galaxy Tab S 10.5 and 3145728 in Apple iPad Air). The range of brightness change in the apple tablet is higher and ranges from 5 to 360 cd / m2, however, deep black color and really high contrast are unattainable for this IPS-screen. Also, the Apple iPad Air completely lacks the ability to configure additional parameters by changing presets. in the corresponding section there is only a slider for changing the brightness. In this regard, the Samsung Galaxy Tab S 10.5 looks noticeably more flexible and comfortable to use.

The% value displays the percentage of the battery discharged in 2 hours of testing, the approximate operating time is obtained by linear extrapolation based on 2 hours of operation in this mode. You can read more about the testing methodology here.

We especially note that in the event that the battery power of the Samsung Galaxy Tab S 10.5 drops to a critically low level, you can use the normal and extreme saving modes. The latter option switches the screen to grayscale mode, limits the list of running applications to a few favorites, and disables communication modules. It is not very comfortable to work in this mode, but when you need to keep the device working at any cost, then you can make not such sacrifices.

Apple is known for being slow in terms of increasing hardware performance. That is why the fifth generation of Apple iPad tablets is equipped with only a dual-core Apple A7 processor and 1 GB of RAM, which does NOT look too convincing against the background of 8 cores and 3 GB of RAM Samsung Galaxy Tab S 10.5. On the other hand, Apple, as a manufacturer of both hardware and software, has the opportunity to optimize this bundle in such a way that “naked” performance doesn’t play such a big role as in the case of universal Android and dozens of different hardware manufacturers.

Geekbench (Samsung Galaxy Tab S 10.5)

Due to the use of different operating systems, it is quite difficult to make an objective comparison of the performance of the Samsung Galaxy Tab S 10.5 and the Apple iPad Air, but it is still possible using the cross-platform benchmark Geekbench 3. The comparison results are very indicative. in most tests where the speed of a single core is measured (Single.Core Score), the leading position is occupied by the Apple iPad Air, however when it comes to system performance, taking into account all available cores (Multi-Core Score), we expect the Samsung Galaxy Tab S 10.5 to come out on top.

Geekbench (Apple iPad Air)

Review of the tablet Samsung Galaxy Tab S 10.5: faster, thinner and lighter than “air”. Controls, connectors

At the top of the bezel of the Samsung Galaxy Tab S 10.5, you can find the manufacturer’s logo, a 2.1 megapixel front camera and a light sensor, and on the bottom there is a control unit. Traditionally, for smartphones and tablets from Samsung, a three-button control unit is used consisting of a hardware Home key and two touch buttons Recent and Back. Touch buttons Equipped with adjustable backlighting and a fingerprint reader built into the hardware.

At the top of the back of the tablet, you can find a neat metal Samsung logo and an 8MP main camera lens with a separate flash. In the lower corners are two original “pseudo buttons”, designed for attaching branded accessories. The manufacturer offers Galaxy Tab S Simple Cover and Galaxy Tab S Book Cover, which snap into THESE two holes. The first cover covers only the screen, while the second protects all the panels of the case and can be transformed into a stand with three different screen tilt angles. Note that both covers are able to automatically turn on and off the tablet screen using built-in magnets.

In the left corner of the top edge of the Samsung Galaxy Tab S 10.5 there is a power button and a volume control, while the infrared port is placed in the very center. On the bottom edge, you can find only a digital microphone, there are no other elements here. The left side of the tablet contains a combined audio port and one of two speakers, the right side contains a second speaker, a slot for microSD and micro-USB cards. Note that the case turned out to be so thin that the developers had to provide for a slight thickening at the port exit.

In terms of port equipment, the Samsung Galaxy Tab S 10.5 definitely wins, since it uses a universal and widespread micro-USB connector, and not the proprietary Lightning connector, and most importantly, it boasts a microSD card slot. We also note the presence of an IrDA sensor, which can replace the remote control, make it easy and quick to change the channel or mute the sound on the TV. The layout of the elements in both models is well thought out and did not cause any special complaints. The only parameter where the Samsung Galaxy Tab S 10.5 clearly comes out ahead is the audio layout. In terms of acoustics and usability, a pair of speakers on opposite sides of the case is a noticeably better solution than speakers on the same side in Apple iPad Air.

The controls are almost identical. in the first and second cases, you can unlock the screen from the front panel using a hardware button. The presence of two additional touch buttons in the Samsung Galaxy Tab S 10.5 is due to the requirements of the Android software environment. Note that the Apple iPad Air has an additional hardware slider switch, which allows you to quickly block the position sensor or mute the sound. In the South Korean tablet, these operations can only be performed using the interface.

We have already introduced you to the stylish ultra-thin tablet Samsung Galaxy Tab S 8.4, but the new Tab S family also includes the larger model Samsung Galaxy Tab S 10.5, which we will talk about in this review. In terms of functionality and hardware, both models are almost identical, however, the 10.5-inch screen provides a much higher comfort for content consumption than its 8.4-inch sibling.

Design, materials

The design of the Samsung Galaxy Tab S 10.5 is completely similar to the design of the younger 8.4-inch model, except for the differences in the dimensions of the two devices. The tablet is offered in the same “dazzling white” (Dazzling White) and “titanium-bronze” (Titanium Bronze) color options. At the same time, both the back cover and the display bezel are made in the main color, although in many cases manufacturers prefer to vary only the color of the back panel, leaving the front one in classic black. By the way, in order to visually separate two panels of the same color, the designers used a silver plastic edging for the perimeter of the case.

The first thing that catches your eye during your acquaintance with the Samsung Galaxy Tab S 10.5 is the unusual proportions of the case for Android models, which tend to be more square than rectangular. Comments, South Korean developers did not use a matrix with a 4: 3 aspect ratio, but they made the border along the short sides of the screen as thin as possible. This decision will be taken with a bang by someone who does not like it excessively “elongated” in the portrait orientation of the body of typical Android tablets. As a result, the dimensions of the tablet are 247.3 × 177.3 × 6.6 mm, and the weight is 465 grams, or only 2 grams more in the LTE configuration.

For reference, the dimensions of the Apple iPad Air are 240 x 169.5 x 7.5 mm, and the weight is 469 or 478 grams, depending on the presence of a 4G modem. A direct comparison shows that the proportions of the review hero are indeed similar to those of an apple tablet with an aspect ratio of 4: 3, since both the length and width of the Samsung Galaxy Tab S 10.5 are about 7 mm longer than that of the iPad. But the thickness and weight of this pair of tablets are almost the same, the difference of 0.9 millimeters and units of grams can only be perceptible with the help of a ruler and scales. In the competition of dimensions, it would be possible to declare a draw (Apple is smaller in area, but thicker), if not for the fact that Samsung was able to fit a larger screen in an identical body (10.5 inches versus 9.7 inches).

Cover the front panel of the Samsung Galaxy Tab S 10.5 with Gorilla Glass. As we said, the border width along the short sides is small at only 8mm. Therefore, when holding the tablet in a landscape position, you will have to choose the position of your palms more carefully to avoid false presses on the screen.

The sides of the case are trimmed with a silver edging, which at first glance looks metallic. In fact, this is an ordinary plastic, painted like metal. The edging of the Home key is made in exactly the same color. Note that the light version of the tablet uses a golden color, while dark brown panels are more suitable for a silver color.

The back of the tablet is made of branded plastic with a dotted texture, the character of which is suggestive of an adhesive plaster. The material is really high quality and attractive. Its surface feels more like soft smooth leather than typical plastic. The dot matrix is ​​easily recognizable to the touch, adding a pleasant variety to the tactile experience of using the tablet. Well, in addition, the plastic of the back panel changes shade when the angle of view changes, which looks at least pretty.

As you can see, the finish of the Samsung Galaxy Tab S 10.5 uses only plastic, while its main competitor Apple iPad Air boasts “solid cast” aluminum body base. Taking into account the smaller dimensions, the specific gravity of the apple tablet turns out to be higher, but it is quite possible to forgive it for the really premium matte aluminum. And no matter how good the perforated soft-touch plastic from Samsung is, the metal has to give way.

Performance and autonomy

Galaxy Tab S7 is equipped with SoC Qualcomm Snapdragon 865 with Adreno 650 graphics. RAM in our version is installed 6 GB, internal memory is available 128 GB. I don’t think it’s worth talking about the problems with the performance of this device. Any heavy games, multiple windows, DeX mode. the tablet copes with all this with ease, while the body of the device does not get warm. The results of synthetic tests only confirm my words.

The tablet is equipped with Wi-Fi 6, Bluetooth 5.0, GPS modules. An LTE modem is also available in our version. SIM card tray aligned with microSD card slot.

The battery capacity of the Galaxy Tab S7 is 8000 mAh. In the PCMark test, the tablet achieved a result of 7 hours 51 minutes. I think on average you can count on 2-3 days with normal use. But here it already depends on each specific scenario. if you use the tablet all day as a second computer, then you will have to put it on charge at night. By the way, the Galaxy Tab S7 supports 45W fast charging.

READ  DIY stylus for graphics tablet

Android tablets are a very interesting category of devices. They seem to exist, but at the same time, the demand for them is falling every year. This is at least due to the increase in the diagonal of smartphones, which is why an additional gadget with a large screen was simply not needed by most users. And yet Samsung is trying to revive the market by releasing new tablet models. Today we take a look at the flagship model Galaxy Tab S7.

Galaxy Tab S7 appearance and accessories

The Galaxy Tab S7 looks like it should be a premium device: thin aluminum body, great build, narrow bezels around the screen. A tablet came to us in “mystically black” a color scheme that definitely adds solidity to it. On the back panel, the place for attaching and charging the proprietary S Pen stylus is nicely played, which visually continues the dual camera unit.

If you hold the tablet horizontally, on the right side there will be a USB-C port, on the bottom there are connectors for connecting a keyboard, and on top there is a SIM / microSD slot, a volume rocker and a power button, which has a built-in fingerprint scanner. The latter, by the way, is located flush with the body and it can be difficult to find it.

Overall, the design, as well as the tactile feel of the Galaxy Tab S7, are commendable. The same can be said for branded accessories. The case, which is attached to the back cover, allows you to hide the S Pen so that it does not get lost, and also has a folding leg for easy fixing of the tablet on a flat surface.

The keyboard is made of matte plastic, which is resistant to fingerprints. The keys are slightly more compact than conventional laptops and are backlit. You hardly want to work with large amounts of text, but to compose a letter or make edits it will do. over, the keyboard received an enlarged touchpad and a block of function keys, when compared with its predecessor.

The new generation S Pen stylus has become even more comfortable to hold in the hand, there is one key to activate additional functions. The accessory is made of plastic, there is a flat edge that magnetically attaches to the side of the tablet or to a special place on the back panel. The S Pen correctly recognizes handwriting input, allows you to take notes in PDF documents, and supports touchless gestures.

Galaxy Tab S7 display

The Galaxy Tab S7 line is presented in two models: in fact, the regular version, as in our review, and the Galaxy Tab S7 variant. And if “a plus” is equipped with a 12.4-inch AMOLED display, then in our case it is 11 “LTPS LCD display with 2560×1600 pixels and 16:10 aspect ratio. The stated maximum brightness level is 500 nits.

Despite the fact that the Galaxy Tab S7 is not formally installed in the top-end display, it is very difficult to find fault with its quality. over, the screen supports a refresh rate of 120 Hz. Thanks to this, the picture is very smooth and you enjoy using the tablet.

Samsung Galaxy Tab S7 Tablet Review

Galaxy Tab S7 sound and camera

The tablet has four speakers, which are located on the side faces, if you hold the device in a horizontal orientation. AKG specialists answered the sound settings, as evidenced by the logo on the back panel. The Galaxy Tab S7 sounds very loud, while being very high quality and rich. Enough to listen to your favorite playlist or watch a movie. True, in games, when you hold the tablet horizontally, you will most likely block one or two speakers.

There are two cameras on the back of the Galaxy Tab S7. The main one has a resolution of 13 megapixels and an f / 2.0 aperture. Additional wide-angle module 5 megapixel, aperture f / 2.2. Supports 4K video recording at 30 fps. As for a tablet, the shooting quality is at an acceptable level, but let’s be honest. you will use the main camera only in extreme cases. But the front-facing 8 megapixel camera is well suited for video calls.

Soft, DeX mode

I think the main problem of Android tablets is the lack of special software for them, because the user, in fact, gets a smartphone shell stretched over a large screen. over, many apps DO NOT support tablet mode, which negatively affects the device experience.

The Galaxy Tab S7 runs Android 10 and OneUI 2.5. Samsung, however, continues to develop its DeX system, which gets better and faster every year. At the moment, it reminds me of Chrome OS. it seems that you have a laptop in front of you, but still you understand that its functionality is reduced. In the new version of DeX, the taskbar has changed, various touchpad gestures are supported, and you can change the zoom. Multi-window mode works quickly, if you pull the application to the side, it will open half the screen.

Still, the Galaxy Tab S7 cannot be called a complete laptop replacement. It can be a useful addition to your device ecosystem, albeit an expensive one. The tablet captivates with its portability, but during operation you will have to make compromises in the form of the absence of the usual software and a more compact keyboard. The device is convenient for relaxation, but again questions arise about the advisability of buying it if you have a smartphone and laptop.

Generating a battery health report

In order to create a report on the battery of a computer or laptop, run the command period as administrator (in Windows 10, the easiest way to do this is to use the right-click menu on the “Start” button).

After that enter the command powercfg.Batteryreport (possibly writing powercfg / batteryreport) and press Enter. For Windows 7, you can use the powercfg / energy command (moreover, it can also be used in Windows 10, 8, if the battery report does not provide the necessary information).

If everything went well, you will see a message stating that “The battery life report is saved in the C: \ Windows \ system32 \ battery-report.html folder.”.

Go to the C: \ Windows \ system32 \ folder and open the battery-report.html file with any browser (although on one of my computers the file refused to open in Chrome for some reason, I had to use Microsoft Edge, and on the other. without problems).

Laptop battery report in Windows 10

In Windows 10 (however, in 8-ke this feature is also present) there is a way to Get a report with information on the status and use of a laptop or tablet battery. battery type, design and actual capacity when fully charged, the number of charging cycles, as well as view graphs and tables of device use on battery and on mains, capacity change during the last month.

This short guide explains how to do it, and what the data in the battery report represents (since even in the Russian version of Windows 10, the information is presented in English). See also: What to do if your laptop won’t charge.

It should be noted that full information can be seen only on laptops and tablets with supported hardware and original chipset drivers installed. For devices originally released with Windows 7, as well as without the necessary drivers, the method may NOT work or give incomplete information (as happened with me. incomplete information on one and no information on the second old laptop).

View the battery report of a Windows 10 and 8 laptop or tablet

Note: As noted above, the information on my laptop is incomplete. If you have a newer hardware and have all the drivers, you will also see information that is missing in the screenshots given.

At the top of the report, after the information on the laptop or tablet, the installed system and the BIOS version, in the Installed Battery section, you will see the following important information:

  • Manufacturer. battery manufacturer.
  • Chemistry. battery type.
  • Design Capacity. initial capacity.
  • Full Charge Capacity. current capacity when fully charged.
  • Cycle Count. number of recharge cycles.

The Recent Usage and Battery Usage sections present battery usage data for the last three days, including remaining capacity and consumption graph.

The Usage History section in a tabular form displays data on the use of the device from the battery (Battery Duration) and the mains (AC Duration).

The Battery Capacity History section provides information on the change in battery capacity over the past month. The data may not be entirely accurate (for example, on some days, the current capacity may “increase”).

The Battery Life Estimates section displays information about the estimated operating time of the device when fully charged in the active state and in the connected standby mode (as well as information about this time with the original battery capacity in the At Design Capacity column).

The last item in the report. Since OS Install displays information about the expected system battery life, calculated based on the use of a laptop or tablet since installing Windows 10 or 8 (not in the last 30 days).

What is it for? For example, to analyze the situation and capacity, if the laptop suddenly began to discharge quickly. Or, in order to find out how “charged” the battery is when buying a used laptop or tablet (or a device from a storefront). I hope this information will be useful to some of the readers.
