Help Android Kernel & Battery Life

[stevez444]

I'm running stock 4.1.2 on my Maxx.

Since the last update my battery life is not nearly as good.

I got the GSam Battery Monitor and it shows Kernal (Android OS) using a ton of the battery life.

I don't remember the android os using a lot of battery before the update.

Is there a fix for this?

Thanks

Was this ever resolved? Couldn't find anything in search.

... and did you try running in Safe Mode (disabling all apps you added without uninstalling them). If the problem stops you know you have a problem induced by an app you added.

have you done a factory data reset since the upgrade?

I have done a factory reset many times and the phone is only a few weeks old as it was an insurance replacement for my Gnex. Was there an update beyond 4.1.2?

I've gone through all the steps of unplugging it and waiting 30 seconds (that's a joke). Could be a bad refurb.

Agreed, I lost 50% battery life with the update. No new apps added from ICS to JB nor did I change my phone usage habits. I went from 48 hours down to 23-24 plus:

A couple apps force close now(games mostly)

Runs noticeably slower when trying to open apps

Surfing the web is faster on a 1995 laptop with a 56k modem than my Razr on 4G(I can literally search for something, get out my other new laptop, turn it on from a cold start, connect and then research my query before my phone has even loaded the page fully)

Wifi doesn't work anymore

And finally(AND THIS IS REALLY RANDOM) JB deleted lyrics from songs. The song information itself is still there, hell even the background music plays when I click on it, but the lyrics and actual singing/rapping/whatever is just gone. I have to re-download about 120 songs because there are no lyrics anymore, just instrumental tracks.

Had I known all this, I never would've updated(Took me weeks to figure out how to update after I deleted some important APKs, turns out my phone was trying to save itself from a downgrade). The battery life itself is a huge downer, the other things I could've gotten over but a loss of 50% of my battery is impossible to forgive.
