Xiaomi Redmi 3 turned out a real surprise and it easily ended up being one of the strongest recommendations we've made this season. The affordable fella is made of metal, packs a 5" 720p IPS display, and runs on the Snapdragon 616 chipset. But the biggest highlight of its specs sheet is the beefy 4,100 mAh battery. The Redmi 3 has been enhanced with the latest MIUI 7 running on top of an Android 5.1.1 Lollipop core. This version of the launcher promises significant battery life optimizations. In fact, we found out Xiaomi has dropped the Performance/Balanced/Battery Saving modes, and now you can toggle only the battery saver mode. Before we continue with the battery life test video, we want to remind you about the change in our battery testing routine. Starting with the Xiaomi Redmi 3, we will be testing all devices on a fixed level of brightness of 200nits instead of merely positioning the slider at 50%. You can read more about what brought along this change in our dedicated Redmi 3 review chapter. Enjoy the video! You can find our full-blown review of Xiaomi Redmi 3 right here.
