Power your phone off. Press the Volume Up and Power keys at the same time to access the bootloader menu. At this time, you can't use the touchscreen to make selections, so use the Volume keys to scroll down to Wipe Cache. It will tell you it can't be undone, but it clears files that may be causing unnecessary battery drain... you WON'T lose anything unless you select the option to do a factory reset. Once you reach Wipe Cache, press the Power key, then use the Volume keys to select that you want to clear the cache. Once it says something like 'Cache Partition Has Been Wiped!", then use the Volume keys again to select Restart Device. Your phone will turn back on as normal, and you should see improved battery life.
Thanks, But even after Chache Wipe issue occurred frequency is slightly reduced but the problem is still there. need to charge the phone 3-4 times a day that also when phone is sitting idle
Same here! Huge battery drain after one ui 8 update. I'm loosing 1% per minute, even if I'm not using the phone. Overall the phone feels smoother and no much laggs as before. Hope they address the issue in the future
