Redmi 7 Review First Impression

Redmi 7 Review – Incredible Battery Life, Same Affordable Price!

Battery Life

The greatest highlight this Redmi 7 review and the Redmi family is the battery life. Redmi 7 is powered by a large 4000mAh battery. It’s 1000mAh more than the Redmi 6 battery. When combined with the low-power Snapdragon 632 and 720P screen, the general battery life is very long. Here are some tests to prove that:

1) Online Video Test

An online video test was conducted on the ‘Bilibili’ client with 70% brightness, 50% volume, starting from 89% power.

After 60 minutes of video playback, the remaining battery was 82%, consuming 7% in an hour. Under the same settings, it is estimated that the Redmi 7 can continuously play online video for more than 14 hours.

2) Gaming Test

Though playing high-end games on low-end smartphones isn’t that much popular. However, with the SD 632 and 720p resolution, such games are easily playable with the highest settings. The popular Chinese game ‘King of Glory’ is a multiplayer online battle arena and is tested on Redmi 7.

In the PCMark Work 2.0 test, Redmi 7 measured 16 hours and 57 minutes of battery life, which even surpassed the 5500 mAh long battery life of Xiaomi Mi Max 3. It is enough to see the level of its battery life.

4) Charging Test

Unsurprisingly, the Redmi 7 supports a maximum charging rate of 5V2A. After all, it is limited by the production cost of the 699 yuan. This seems to be reasonable.
