Help Battery life after JB update.

So after I updated my Optimus L9 to JB 4.1.2 my battery life seems to be slightly worse. I noticed that "Cell standby" takes up more battery consumption than it used to which is strange because in 4.0.4 the screen took up most of the consumption.

Any ideas on why this could be?

I think you would get more responses in your device forum rather then the lounge, if you want your post moved there just let us know, cheers

Some people have reported that performing a factory reset after the update from ICS to JB fixed some bugs that they had. It worked for me too.
 
Not the same phone but I had the same thing happen after putting it on my old HTC One X, a factory reset and disabling google now sorted it out and I actually ended up with better battery life than on ICS
 
when you get an OTA update like this it is recommended to do a factory reset. it sucks that one must wipe all their apps/settings just to update but a 'dirty flash' only causes battery life to drain quickly and the system is far more unstable if you don't. i haven't even been able to boot a phone with a 'dirty' update without constant 'com.android.process.acore' force closes, forcing me to reset to make it even function.

although i have never had Google Now impact my battery life at all...not sure where that started from. Google Now has no more impact than any other sync-compatible app such as Facebook...

I'm not getting any errors or force closes.

Thanks guys, this is what most other users have suggested in other forums that I've looked through. It looks like I should give this a try.
 
i've never been lucky enough to get the update that didn't send my device into either a boot loop or produce endless repeating force close errors. some get past that and boot fine but the device is slow, unstable and eats battery.

Well my only issue is battery, the phone performs noticeably faster and it was pretty snappy on ICS before.

It was widely reported on the One X forum that google now was impacting battery life.. I did a process of elimination on mine and it definitely improved after disabling it.. there has been updates to both the one x and google now since then, this was when JB first came out so things may have changed now, I no longer have that phone.

Don't forget to make I backup before you do a factory reset. I used 'Helium', it backs up apps + data (like progress in games and settings you did in apps).

Yea i discovered that app last month, it was great when I bought my L9 and didn't have to download my apps again.

My battery seems fine since the update but where do I find google now to disable it? I don't see anything called that. Mary
