Hi, what are you looking for?


Best battery life phone to buy

Every year, manufacturers have been looking to extend autonomy with their smartphones, either by including a battery with greater energy capacity or selecting components that consume less energy, such as advanced processors of 10 nm or less.

Several devices have passed through the TudoCelular bench in recent years, and here we will list the 5 best in each category (entry, intermediate and advanced), but only models launched in recent months that can be easily found on the market. It’s no use recommending a device that no one can buy, is it? If it is an imported model, we will also include a purchase link to a store we trust.

The devices are divided into three groups: entry (up to R$1200), intermediate (between R$1200 and R$2500) and advanced (over R$2500). We take into account the current average value at the end of 2020 and not what was practiced at the product launch. Due to the constant fluctuation of prices, we give a small margin of R$200.

Below you can find our reviews of each model, which include the battery tests performed, as well as all aspects of the smartphones listed here. And we also have a complete ranking with the latest models analyzed.


  1. really C25: 41:46
  2. Motorola Moto G10 Power: 33:46
  3. Samsung Galaxy M22: 33:37
  4. Samsung Galaxy M12: 31:03
  5. Motorola Moto G7 Power: 29:08

1. really C25

Presented in Brazil as a cost-effective device for gamers, the realme C25 is today the champion of our ranking not only in the entry-level device segment, but also in the general list, where all devices tested so far here are considered. TudoCelular, thus stealing the title until then guaranteed to the Motorola Moto G7 Power.With more than 41h of autonomy in mixed use in our tests, the realme C25 also stands out for being a device that fits in the pocket when thinking about budget and delivers a nice set for those who want a device for everyday life and even a game to pass the time.

2. Motorola Moto G10 Power

Part of the generation launched in 2021, the Motorola Moto G10 Power is, as the name implies, the brand’s bet for those looking for more autonomy among entry-level devices. Obviously, the company did it and in our tests, it managed to resist for almost 34 hours in our standardized tests.

3. Samsung Galaxy M22

Currently one of the devices with the best battery performance in our tests, the Samsung Galaxy M22 managed to reach 33:37 total usage time in our tests, which includes more than 16 hours of screen on, thus showing that the device can easily pass the entire day away from an outlet.

4. Samsung Galaxy M12

Continuing with our TOP 5 basic battery life, we have the Samsung Galaxy M12, a device that brings an updated look and cool hardware, without giving up a killer battery to keep you away from the socket all day, being obtained in our tests the expressive mark of 31:03.

A point worth mentioning when we talk about the Samsung Galaxy M12 is that it is also the best autonomy when we talk about devices with screens with a refresh rate above the standard 60Hz, in which case 90Hz is offered to its users.

5. Motorola Moto G7 Power

Two and a half years have passed since the launch of the Moto G7 Power and it is still in our TOP 5 for autonomy. Not only among the most affordable cell phones, but it’s the one that delivers the best battery life of all the devices we’ve tested — and not a few. We expected the Moto G8 Power to be able to surpass it, but Motorola failed in the mission.

It won’t be long before the Moto G7 Power disappears from the shelves, especially when the Moto G9 Power launches soon. If you want to have the best drums, run. Its price has fluctuated a lot. Before it was found for less than R$ 1 thousand, but now it has a similar value to its successor.

Check out all the basics side by side

  2. really 8 pro: 33:21

1. Samsung Galaxy M62

Recently presented as a device that stands out for bringing considerable advances in hardware without giving up energy autonomy, the Samsung Galaxy M62 managed to secure the leadership in our TOP 5 of intermediate devices when it comes to usage time.

In our tests, the device managed to reach 40h41 of total autonomy, surpassing the until then leader realme 8 Pro in more than 7h when compared, showing that it can be a good option for those who want performance without having to charge during the day.

2. really 8 pro

Bringing interesting hardware and differentiated visuals, the realme 8 Pro guaranteed good results when we talk about energy autonomy, nailing in our tests a total autonomy of 33:21 and being ahead of its brothers realme 7 5G (28:31) and realme 7 Pro (22:25) .

In addition to the excellent battery life, the realme 8 Pro charges fast, offers good gaming performance and takes good photos, something in part boosted by its 108MP main sensor.

3. really 9i

Another good option when it comes to an intermediate device with good autonomy is the realme 9i, a device that in our tests guaranteed the 30h42 mark, as well as being competent in charging, taking 1h22 to charge, a mark that can be considered reasonable for the segment it positions itself.

4. Redmi Note 10

The crown when we talk about intermediate devices is in the hands of the Redmi Note 10, a device that has recently managed to secure first place in our energy autonomy ranking, managing to reach the end of its autonomy with 30h33 of use.

Not least, the device managed to arrive at 15:39 when it comes to screen time on, that is, most likely you will be able to use it throughout the day without having to resort to the charger.

Where to import:

  • Redmi Note 10 4/64 GB at Banggood
  • Redmi Note 10 4/128 GB at Banggood

Moving on to the vice-leadership, we have the Samsung Galaxy A32, a device that recently arrived in Brazil and that did well when we talk about autonomy, managing to be very close to the Redmi Note 10, when fully unloading in 30:30.

As for autonomy with the screen on, we have similar results with the Redmi device, being possible to stay interacting for 15:34, showing that it can also be an interesting option in autonomy.

1. Apple iPhone 13 Pro Max

And officially, we have a new autonomy leader here at TudoCelular. After much criticism from users regarding the time of use, Apple has been gradually getting its hands on the improvements implemented and the iPhone 13 Pro Max crowns this effort, managing to arrive at 30:41, of which 15:04 were screen on in our tests.

Yes, you’re not seeing it wrong… The Apple iPhone 13 Pro Max managed to do well on battery power to the point of rivaling intermediate and entry-level devices at the top of the usage time chart.

3. Xiaomi 11T

Xiaomi’s first device in this top 5 of advanced devices, the Xiaomi 11T managed to get it right by delivering a result superior to what we saw in the previous generation (calm down, we’ll talk about it later), passing very close to 28h in our battery test.

4. Xiaomi Mi 10T

Another advanced device that also did well in terms of energy performance was the Xiaomi Mi 10T, which has the Snapdragon 865 on board and managed to guarantee almost 27 hours of autonomy in mixed use (26:55, to be more exact) in tests here at TudoCelular.

5. Samsung Galaxy S21 Ultra

Speaking in particular of the most advanced devices available on the market today, we have the crown for the best battery with the Samsung Galaxy S21 Ultra, a device that offers a generous 5,000 mAh battery and was able to last 26h26, including 12h14 with the screen on until its battery was completely drained.
