Battery slow charging and drains fast after last system update.can i just replace battery?
Hi Stella. From the home screen, tap Boost Zone. Swipe to the left to open Device Diagnostics. Tap Battery Status. You can check there the battery's performance. If you think the battery's performance has worsen, what I usually do first in such cases is drain the battery and fully charge it while it's off to see if battery works normal again.
