Battery life short with NG6 upgrade

Member

My phone upgraded to the NG6 software and since then my battery life has dropped to less then 5 hours on a full charge. Something seems to be pegging my processor and draining the battery. When I look at the battery screen it shows the Android OS using 60-80% of the battery which never used to be the case. In one test, I charged the phone and put it in airplane mode and didn't touch the phone for 4 hours. In the 4 hours, the phone battery dropped from 100% to 36% and Android OS was 61% of the battery usage. In the past, I could run for days in airplane mode with no issues. The only way to fix this is to reboot the phone but as soon as I use the phone again the battery starts draining quickly again. Has anyone else had this issue and is there a fix?

that's no good... I wonder if there is one of your 3rd party apps that isn't working well with the new update and causing a strain on the OS... You might try running the device in safe mode and seeing if that improves your battery life. You won't have access to any of your 3rd party apps, but its good for diagnostics. If it works better in safe mode, then you have to try and figure out which app is making trouble, which is a whole other task (process of elimination.)

Restart the Device in Safe Mode - Samsung Galaxy S® 4

If that doesn't do the trick, I would maybe consider doing a backup and factory data reset.

There are a couple of threads on this issue. No solution yet unfortunately.
