Horrible battery drain with JB update....

[HTC1]

Agree

When you say 3 to 4 days standby.... is your phone just sitting there because before this update I would get from 6 am to midnight, which works for me, but I really text mostly and check emails with maybe 1 half hour call a day.

I rarely have to charge my phone, honestly. I use it on a daily basis, but not heavy use. With heavy use Im down to about 74% the next morning. And this has to be the most incredibly fastest charging phone ever.. If I'm at 74%, if I plug it in, will be at 100% in less then 10 mins.

And when I say standby, I don't mean not using it. I mean I can simply put it down and use it when I need to without having to plug it in.

That's how mine was on ICS. Now I too have crazy battery drain. I might be going back to ICS.

Sorry if I missed it,m but have you tried Battery Saver in settings?

After the update, I noticed Google Maps was sucking a ton of juice, even though I wasn't using it. I turned off all of the location services and history options in Maps, and I think that solved it. I also turned off Google Now, which I suppose could have been the culprit as well since it relies heavily on location based information. Either way, the useless 20% drain I was experiencing is solved.

Jeese turn on battery saver!

Man I'm telling you, this isn't everyday normal battery drain from too much use. This is obviously extreme drain to where you know something is wrong. Plus I still shouldn't have to use it unless absolutely necessary. I don't think I've even used it once since I bought the phone. And I also use my phone for games, and the battery saver really does slow them down after 50%.

Unfortunately I was busy yesterday so I didn't get a chance to backup/reset but hopefully I'll get to it tonight.

Yeah I went to sleep with over 23% and woke up to my phone dead... Usually 23% lasts me all day if im not using my phone.

^^For sure. Mine would've been closer to maybe 15% if it were like it used to be on ICS...depending on how much sleep I got.

Now did the FDR help your battery life at all? Also did you take it OTA or flash it?

FDR didnt help a thing from what I can see. All my problems are still there. And I took the OTA

At first I thought FDR helped mine, but not the case. Yes, I have battery saver on. But I shouldn't have to start turning off Maps, Google Now, and such that rely on location. I like location on for weather, etc.....Obviously a battery draining bug in JB...With the exact same settings, ICS lasted a day and a half easily....If I can get 8 hours now with JB, I'm lucky!

I agree, but unfortunately it just might be the case until google rectifies this. The good news is that my battery life is now better than ever.

I also noticed significantly increased battery drain after the update. I switched my Network from Global to CDMA/LTE thinking maybe it was wasting energy scanning both radios, but I think the real killer was a couple of other settings that the update (re)enabled that I had turned off; the SmartStay option in the Display settings, and the option in S-Voice settings where it continuously monitors the microphone, waiting for you to say the 'magic wake-up command', that one even says it will drain your battery! With all that stuff on, my battery usage list would show "Screen" as the top item, and that was with the phone sitting untouched in sleep mode for several hours after taking it off the charger! I also found a couple of the "location update" related settings turned on that I was pretty sure I had disabled. I'm not sure which of those made the most difference (I suspect it was the S-Voice thing), but after putting all that back the way I had it before the JB update, my battery usage is back to normal.

If you haven't already checked those, give it a try.

 

[MyEntityRemains]

I just tried your suggestions. Will now wait for results.

I reset today and everything is exactly back to how it was. I used to always use SmartStay on ICS with no problem, but I'll try turning it off too. The S-Voice setting makes a lot of sense though.

Only thing is Android System is generally the biggest battery killer for me. So I think it has something to do with either WiFi or GPS. Guess we'll find out...
