Re: [Help] Unexplained heavy battery drain...occurs randomly

I don't know if you're rooted or not, but I found this thread over at xda when my phone was getting really hot.
[Q] what is Gsiff_daemon and why is it destroying my battery? - xda-developers
Seems like there's a system process that's draining the phone, doesn't seem to be specifically app related, possibly something to do with the motion sensors or GPS. Unfortunately, doesn't really look like there's a firm solution (other than rebooting/ returning the phone) but I'm sure if anyone can find a solution, it's those guys.
Good luck!
Switch network mode from LTE to HSPA only. Saves me tons of battery life
Sent from my SGH-I747M using Android Central Forums
The temp seems to rise when the plummet begins. No clue
So I am noticing this exact problem too. Same as Jefreii. The seemingly "random" triggers that cause way excessive battery drain, with LTE, Wifi, GPS, Sync, phone, screen off, and disabled Google+, very close to stock apps. Already exchanged device and changed SIM card.
Besides these random drains, I feel the battery life is excellent. Not an expert but really want to figure out.
1) Are only people who are in LTE locations with AT&T experiencing this? I am currently looking into if the phone is triggered only when network is LTE and bad signal. (not LTE data radio on, but just phone). Under Settings->About Device->Status->Network
Sitting at work right now and the network changed from HSPA:11 to LTE:14, and temp just went up and battery will start to drain. Again, with 4G LTE data radio off.
2) Does anybody have any good workarounds -> Currently I have my phone alarming when Temp > 30. Does Tasker or any other app allow automatic reboot based on temperature trigger. Otherwise was thinking of automatic airplane mode when Temp > 31 or something, and cycling in and out of airplane mode until I can reboot manually.
Thanks.

I'm sorry to sound like a broken record (I've said this 3 times now I think), but you need to use a monitoring app that will break down android system processes for you to see what's causing the drain. Have you tried that yet?
If you're confident it's not a weak signal issue, then it's gotta be a process that's grabbing lots of cpu. You need to find out what process that is.
@jeffreii
Maybe you mentioned this already and I missed it, but why haven't you just returned your phone? If a factory reset doesn't fix it, then for pete's sake return the phone and have AT&T give you a new one.
Yes I saw your screenshots but it looked they just lumped all the system processes together as "Android System". You need a way to get some clarity into specifically what the CPU time is for each of those system-level processes. Maybe the apps your using will give that level of detail, but based on the screenshots you posted I couldn't tell. Again, I'm a fan of the app "System" which will usually give you the breakdown of specific system processes. It's not free, but I don't think it's too expensive. Might be worth it if leads you to the culprit.Thanks minsc but I've already exchanged the device (see post #1) and have posted my Better Battery Stats logs/screenshots as well as GSAM Battery Monitor screenshots extensively in this thread. If you can take a look and find anything please let me know but please read my posts first as I have done a ton of troubleshooting/logging/tests.
Thanks again!
BTW before I try a 3rd factory reset and use it with no apps installed, I am trying one last scenario. I turned off wifi and rebooted. I will not enable wifi again until I see the plummet occur again, at which point it's factory reset time.

As you are speculating, it could be a radio problem too. Either way your're in tough shape I'm afraid. I would exchange it again; if for no other reason than AT&T has proof of the issues your having. No one should have to be putting up with issues like this on a phone that's under warranty. Have you considered a switch to the One X? Not that I'm encouraging you to throw in the towel, but at some point you need to move on and have a working phone.
