Best Battery Life Phones of 2021: The Real Test

Which smartphones have the best battery life? Best battery life phones aren’t necessarily the most expensive ones. They could belong to any price category – High-end, mid-range, or budget.

No matter how bigger the camera is and how larger and sharper the display is, smartphone users don’t seem to compromise on the phone’s battery life.

So without a second thought, whatever you want from your phone, one aspect is unquestionable –  it ought to belong to the league of best battery life phones.

PhoneYear does rigorous testing of smartphones for their performance. We test them in different ways, as close to real-life scenarios as possible. Some of our tests include;

  1. draining phones entirely by running videos in a loop
  2. monitoring the drain pattern on 4G data with different resource-hungry apps
  3. Playing online games on 4G data

Head over to our list of the best battery Android phones that can fall within most smartphone users’ budgets.

We have handpicked some of the best players you may consider at the time of your next purchase.

  2. Realme 8
  3. Xiaomi Redmi Note 10
  4. Vivo V21
  5. Vivo Y31
  6. Tecno Pova 2
  7. Infinix Hot 10s

Realme C25 (30 hrs)

realme C25 remains on the top of our list of best battery life phones, although realme released a sequel, C25s.

Despite featuring an upgraded chipset and similarly powered battery, the latest version doesn’t stand in front of the original C25.

It’s a budget smartphone boasting a mega 6000 mAh battery and Mediatek Helio G70 chipset. The combination gave an insane battery drain time of 30 hours in our video loop test.

And being an entry-level device, it takes 3:30 minutes to charge fully.

C25 also showed an impressive battery drain percentage on 4G mobile data.

Realme 8 (25:43)

The Mediatek Helio processor is once again a performer but in a better-specced phone. 

Realme 8 comes with a Mediatek Helio G95 chip and can give you a continuous video backup of almost 26 hours with a 5000 mAh battery onboard.

The smartphone gets back the whole battery power in just over an hour through its 30W dart charge.

We found realme 8 doing excellent with performance and battery life; however, the same is not true for the camera.

Xiaomi Redmi Note 10 (25:09)

Xiaomi Redmi Note 10 is perhaps an all-rounder in our list of best battery life phones. 

The smartphone is not far behind realme 8 when it comes to drain time (25:09) and even the charging that can happen in almost 78 minutes. 

You can expect a 15% battery drain on games like PUBG that isn’t very unimpressive, especially when you are getting Snapdragon 678 and 4GB RAM.

Vivo V21 (22:05)

Ever since Vivo S1, the company has paid much attention to the design language and, of course, the battery life. 

We still remember from our list of 2020, Vivo Y51 giving us 21 hours and 39 minutes of video loop backup.

Today, we can experience similar efficiency in Vivo V21. A slim design and a 4000 mAh battery can last as long as just over 22 hours, and its 33W FlashCharge can replenish the battery in 1 hour and 17 minutes.

Though it lands in our list of best battery phones, it can drain above-average battery life at the time of video shooting, and we noted it around 14% in 30 minutes.

Vivo Y31 – 2021 (20:53)

We have another Vivo smartphone sitting next to V21. The Vivo Y31 2021 edition is slightly cheaper, but it performs much better on 4G data in terms of battery consumption.

Its 5000 mAh battery could survive 20 hours and 53 minutes, whereas; it took almost 2 hours to refill its battery.

This phone features a Snapdragon 662 chipset, 4GB RAM, and 128GB ROM, and on top of it, a 1080×2408 display.

Tecno Pova 2 (19:54)

C25’s closest rival, Tecno Pova 2, survived for almost 20 hours in the video drain test even though it features a 7000 mAh battery – still an excellent drain time compared to the rest of the competitors.

The good part about this phone is that it gets charged in 2 hours and 40 minutes approximately through its Type-C port, and the performance on 4G data is at par with realme C25.

So if you are not into binge-watching, Pova 2 with its Mediatek Helio G85 chipset can be your choice.

Infinix Hot 10s (18:55)

The 6000 mAh battery on this cheap device can give you almost 19 hours of video loop backup. 

When it comes to charging, a 3-hours session seems long enough compared to what Tecno Pova 2 does in lesser time.

Samsung Galaxy A12 (14:37)

One of the cheapest Samsung phones and the last in our list best battery life phones gives HD display and an older MediaTek P35 chipset – a combination that makes possible its 5000 mAh battery to just past 14 hours during our video loop test. 14:37 to be exact.

Samsung Galaxy A12 charges in two hours. Design-wise, the phone looks good in hands; however, the battery consumption on 4G data is slightly higher. 

The phone features an HD display, an Helio G85 chipset, 6GB RAM, and 128GB ROM.
