I have a Micromax YU Yunicorn, it doesn’t charge after 85%. Initially it didn’t charge after 98% then 88% then 85% . Please help.
Discharge your phone completely — run it down until it shuts off. Then charge it up as far as it will go, and discharge it one more time. Hopefully this will calibrate the battery to register its capacity properly. If it doesn’t, then you’ll need to replace the battery.
