The autonomy of smartphones is a rather individual, if not evaluative, thing. It depends not only on how you use your device, but also how you perceive its operating life without recharging. Some people, for example, believe that a smartphone should work from morning until evening, when it can be plugged in again. And who, on the contrary, sincerely believes that a week is the necessary minimum that every mobile gadget should last. I don’t consider myself one or the other, but I don’t look at autonomy the least.
The autonomy of Android smartphones is traditionally higher than that of the iPhone, but only if we are talking about flagships
Xiaomi smartphones are complete trash, but its speakers are simply royal. I was convinced personally
Looking ahead, I’ll say that if you find a smartphone on this list that you like, but want to buy a device that will last as long as possible, focus on one simple indicator. Of course, we are talking about battery capacity. After all, no matter how energy efficient the processor is and no matter what scenarios you use your phone in, rest assured that a 5000 mAh battery will behave much better than a 2500-3000 mAh battery.
Smartphone autonomy rating 2021
Moto G Power is the most autonomous Android smartphone
The test that allowed us to compile this rating involved continuous web surfing at LTE speeds. This may not be the most objective experiment, since it did not involve watching videos, making calls, or taking photographs. But, given that we all have different scenarios for using smartphones, only the test that each of us conducts independently can be called objective.

The best Chinese smartphones under 15,000 rubles
As you can see, in most cases, smartphones with the highest battery capacity are in the top, although, of course, there are also plenty of exceptions. For example, it is strange to see at the end of the list the Galaxy S20 Utra with a 5000 mAh battery and the iPhone 11 Pro Max, which, although equipped with a battery of less than 4000 mAh, still has the highest optimization in its class, which means it could well If not to lead this top, then at least stay somewhere in the middle.
Smartphone HUAWEI P30 Pro – 4200 mAh
Modern smartphones are becoming increasingly similar to each other, but Huawei has found a way to make its latest device, the P30 Pro, . Apart from its optical zoom feature, attractive color options and amazing camera, it has an impressive battery life.
The 4200 mAh battery provides 8-9 hours of screen time when connected to Wi-Fi and in auto-brightness mode. Even after browsing the Internet, watching YouTube videos and playing games, you can be sure that the device will not run out of charge. Moreover, if you plan to use the phone on a cellular network, you will definitely get an extra hour of battery life, giving you 9-10 hours of use.
In addition to its impressive battery life, the P30 Pro features an OLED screen with great brightness, pixel density and contrast. The default setting is Vivid mode, but you can easily adjust it to your ideal color. The quality of the camera is second to none. The P30 Pro has three rear cameras: a 40MP rear camera, a 32MP front camera, and an 8MP telephoto camera.
The 40MP camera delivers detailed images with vibrant colors, excellent dynamic range and excellent white balance. What's more, the pixel binning feature means the 40MP camera can save 10MP images by default. Its zoom capabilities are also impressive in an era where most mobile devices support digital zoom. The P30 Pro allows you to magnify subjects up to a whopping 50x, allowing you to capture images with more detail, separate your subject from the background, and frame your shots better.

What uses up the battery in a smartphone?
- high screen resolution
- challenging games
- recording materials in 4K
- GPS works
- wireless communication modules
- background applications running unnecessarily
It is generally accepted that the larger the screen, the faster the battery drains. To some extent this is true, but resolution is also important. If it is not too high, the maximum is FullHD +, even in a smartphone with a large display you can work for a long time on one charge. Moreover, such models usually offer batteries with high capacity.
Of course, even in the case of higher resolution displays you can count on good battery performance, but then a lot depends on its capacity, as well as other components and software optimization.
The best examples are Xiaomi Redmi Note 8T (6.3 inches) or Samsung Galaxy A71 (6.7 inches). Despite the large displays, they provide a long talk time or browsing the Internet, which is confirmed by most tests. Especially if you take care to set the display brightness correctly.
An important issue relates to performance. Higher-performance processors—especially older ones made with older manufacturing processes—may drain more battery life. Especially if they will often work at maximum load. For example, when playing demanding games or recording 4K videos.
Other items that can significantly drain your battery include running GPS, wireless modules, and background applications. Even optimizing the operating system is important, but you cannot influence it.
It is important!
Many people believe that high battery capacity indicates record battery life. But in the world of Android smartphones, this is not always the case. Operating system optimization, display technology, type of processor installed, and many other factors influence the operating time on a single charge. Therefore, a large battery capacity does not always guarantee excellent autonomy.
There are a lot of devices with incredibly capacious batteries. Our top contains only those that have good characteristics. Also, all of the listed models collect much more positive reviews than negative ones.
There is no need to assume that to create the rating, we selected only smartphones with the most capacious batteries - such copies are often too heavy, and their characteristics quickly make you think about replacing the device with some more advanced model. True, by 2021, smartphones with large batteries have become lighter and prettier, but models with the most serious batteries are still bulky and heavy.
Xiaomi Mi Note 10 Lite (10 hours 9 minutes)
Xiaomi Mi Note 10 Lite , like the previous version, pleases with pleasant little things: it also has an audio output, an infrared port, and an NFS module, thanks to which it is easy to make payments in stores. The main characteristics are not much different from the old model: it has the same 6.47-inch diagonal, AMOLED matrix and oleophobic coating.
An interesting feature in the smartphone is the “Video blogs” mode; by the way, it is found on all Xiaomi . Thanks to this mode, the user can create short videos with additional animation and filters. The result will impress you! If we talk about autonomy, the smartphone has a 5260 mAh battery in its arsenal. During testing (watching a video in airplane mode and minimum brightness), the smartphone worked for 23 hours. You can count on 10-hour battery life on the Xiaomi Mi Note 10 Lite .
What should the battery capacity be?
Given the questions above, it is impossible to answer this question directly. You must balance the battery capacity with other components, as well as what the device will primarily be used for.
It is believed that a good battery has a capacity of at least 4000 mAh
In such cases, it is likely that the charger will not need to be used more than once every two days. Moreover, the less efficient the smartphone, the better the battery performance.
Given the questions above, it is impossible to answer this question directly. You must balance the battery capacity with other components, as well as what the device will primarily be used for.

Under the hood, the smartphone hides a powerful chipset – Apple A14 Bionic, the safety margin of which will be enough for several years to come. Apple boasts a scanner: it accurately measures 3D objects, rooms, etc. Despite the depleted battery, the iPhone 12 Pro Max works as long as the manufacturer promises.
