If you are rooted, wipe battery stats Byby using the battery Calibrationcalibration app on Playstore IfPlay Store. If not, then I suggest taking it to Device centrethe device center because it looks like your phonesphone's battery has got old and lost itits retaining power /actual capacity has been reduced Or. Or it may be a ROM issue, I cantcan't tell because youdyou didn't mentioned manufactrersmention the manufacturer's name.
