Xiaomi Redmi 2 battery life test

Xiaomi Redmi 2 stopped by recently and we did what as we always do – a thorough hardware and software inspection for our traditional in-depth review. The Redmi 2, unlike its Redmi 1S predecessor, is a dual-SIM device with LTE connectivity, courtesy of the Snapdragon 410 chip inside the newcomer.

The Redmi 2 battery has 10% higher capacity, while the display and overall performance have been kept the same. We are eager to check how the new hardware and MIUI v.6 are doing with the 2,200 mAh battery unit.

Our first test gauges the 3G call performance and the Redmi 2 did well here, lasting about 12 and a half hours. This is two hours behind the previous Redmi 1S model, but still enough.

Finally, we left a video sample on a looped playback. It managed to run for 8 hours straight before the battery went down to 10%. It’s definitely a good result and you’ll be able to watch at least three full movies and then some more on a single charge.

The dual standby performance turned out very good at about 15 days and surely improved the final endurance rating. Note that the standby endurance is not listed in our score card, but it is calculated in the total endurance rating.

So, the final endurance rating of 57 hours means the Xiaomi Redmi 2 will last for two days and then some if you do an hour of calls, an hour of video watching and an hour of web browsing each day.

Our battery testing procedure is described in detail in case you want to learn more about it.
