Samsung Galaxy S4 — Discharged batteery

Îgli Xhåfã

hello, I have a i9505 galaxy s4, that when I made kit kat version 4.4.2 with battery discharged soon can you help?

This is a common problem
To solve the problem go to recover and clear cache

to enter recovery
Power off your device
Press and hold ‘Volume Up + Home + Power’ buttons together and release them as soon as you see the Galaxy S4 logo on your phone’s screen.
Your phone will boot into recovery mode. Use Volume buttons to navigate Up and Down between options and use Power button to select an option in recovery.

4.4.2 has a battery draining bugs..
since you cannot downgrade , you can delete unnecessary apps and games which drains battery
it is your Google Play Services that are killing your device. This issue has been occurring ever since 4.4.x

I would recommend doing a backup of your apps and data then doing a factory reset and clearing the cache through recovery and then rebooting, restoring your apps and data and seeing how you go. Usually that's all that's required to avoid battery drain problems following a firmware update.
