Battery Drain problems...please help. - Epic 4G Q&A, Help & Troubleshooting

Sometimes, when I go into buildings (like a movie theater or college class room) my phone gets hot and then the battery just drains crazy. I have Sprint Optimizer off and I don't think it is Rom related because it dosen't matter what Rom I use, this happens. My guess would be that it is constantly trying to find a signal or something...if that is the case, what do I do? I shouldn't have to put my phone in airplane mode when I go into a building. Let me know your thoughts or solutions....Thanks!

Do you HAVE signal when this happens? Could it be an app running your CPU and wakelocking you? Is GPS trying to get a fix for something?

I do have signal.....but it is very very slow....I don't know if its a app running...I always keep gps off unless I need to use it. Next time it happens, is there something you recommend that I do to help find out what is causing the problem?

You can use CPU Spy to see if your phone is staying awake or sleeping. Also, Better Battery Stats will allow you to check for specific wakelocks.

To the OP, if you use these make sure you un install them when you're done with them. They reduce your battery life because I think they make wakelocks of their own.

For me, battery drain and excessive heat remind me of one thing - heavy data use. This happens to me when my drop box is automatically uploading my gallery, while signal is bad.
If this were happening to me I'd be looking for apps that are auto syncing or auto uploading data and change the settings.

Take a look at these battery stats: all of a sudden, my battery life is crap!

So, I've been using CleanGB 1.1.2 for a few weeks, and I tried flashing a cm7 rom. Didn't like how much issues I was having, so I restored my old CleanGB rom. Ever since, my battery life is pathetic. I have an extended battery, usually charge it from 40% to 100% while I sleep. Now, its always charging because it dies so fast.
Take a look at the links, anyone have any answers? Thank you!

Try wiping battery stats....
If you don't know how the process works you can look at Qbking77's video on it- http://www.youtube.com/watch?v=JbYVv4nCveM
Percentages don't tell us anything. What is your display on time? What is listed in running services? How much deep sleep is your phone getting? These are all that matter, not the battery screenies.
If you have 30 minutes screen on time with high intensity and are syncing something in a poor signal area that percentage is typical. If your phone is just sitting there and it drops that much an hour later then there is an errant app not closing.
Wiping battery stats does nothing... id recommend follow kenny's advice here, we can't really help you if you don't help us help you =].

How can I prevent apps from opening in the background? Like, games for some reason are in my backgrounded apps. I never opened that game, so why is it starting?
Any advice on making sure these apps don't start unless I make it start myself?

Problem is clear, all stats are fine except android system and display,no way is display that low it should be at least 60% the higher the better as it uses the most battery out of the lost batt, android system is way to high and I don't think there is a way to check what exactly it is, I would say flash a new rom.I had abnormally high cell standby and the other cell think I forgot the name haha, flashed a new rom (reaper 2.2.2) and I've had normal stats with display using the most.

They preload part of their code so that they open quicker when you want them. You can either use Autostarts to stop them or get paid version of Titanium Backup and freeze them until you want to use them or uninstall them.

That is just a misreport. It groups everything the phone does (basically being on except deep sleep) into Android System. The important stat is Display time.

What's your screen on time.
Looked kinda like liteflow might be causing problems?
Cell Standby i think is the one that is coded wrong and is lying, ignore that one.
If you press Android System in settings, battery it will show you the top components being used
Also in dev options look for and check Show CPU Usage. It will show whats using the cpu in the top right of your screen. Watch for what stays in the top few spots in the list.
There may have been something that didnt like the update. Try first uninstalling apps and if that helps reinstall them clean, no data restore. If you continue to have problems backup all data and factory reset. Start clean.
If all else fails use odin to flash the full LH2 fw.
LH2 should be a fairly stable build. Most have no issues and many get outstanding battery life. Im willing to bet its either an app or the way you updated or both.

That's really not THAT bad for a screen on time. I saw your screenshots in the OP, and you were down to 80% in only two hours of being on the battery, but you had the screen on for almost an hour of those two hours; 20%/hr for the first few hours is pretty normal. It's not stellar, but I wouldn't say it's an epic drain that being said, I'm sure you could squeeze some more juice out of it, and prob is just an app causing more drain than usual.
Also when doing a screenshot, it helps to hit the power button first, then the volume, so you don't get the volume pop up every time.

Cell data power consumption

Just wondering if anyone knows why when I turn of data especially, my phone can go 24 hours in one charge but leaving data on all the time diminishes the battery life. Is it a modem thing? I always had battery issue but turning off data seems to help a check lot. Thanks in advanced.
Sent from my SGH-T999 using xda app-developers app
Do you often leave the coverage area? Because constantly searching for network when there is none will eat battery. Also If you have data on it will allow background apps to use the internet, which consumes power as well.
You probably are getting a much stronger signal when it isn't trying to stay connected to mobile data.
The weaker your signal the greater the battery drain. Often when you enable data you get a weaker sig.
Also make sure its not set to wcdma only.

I'm in pretty good coverage area.
Sent from my SGH-T999 using xda app-developers app
It is pretty normal for you to have more battery consumption with the data on than off. I had a myTouch 3G slide that could go for 3 days if I left the data off. Check to see if you have any apps that are being synchronized too often because that could be causing your phone to die quicker than normal.
With data off apps can't update(refresh) right? That should keep them from waking the system up.

If they are set to sync they will still try. You have to turn off sync. But if they can't get out they still don't transmit so still less battery use.

Yeah that will probably fix the issue. When I was on TW, under the battery tab, I noticed that my phone would wake often during the night. Now with the data off, it stays asleep longer. I think ill have to use something like juice defender that enables and disabled data automatically

Can't get rid of wakelocks

Battery life was great but all of a sudden now I'm getting horrible battery life, now lasting only 4-5 hours. Based on BetteryBatteryStats, it seems i have a wakelock issue and phone never enters Deep Sleep. I've searched the internet for solutions and have tried several things
- uninstall Google Chrome
- disable autoscroll
- hard reset
- reformat SD card
- get rid of SD card
Im still having poor battery life and even when I turn off WiFi, mobile data, gps etc, phone still never enters Deep Sleep.
Here are some screen shots. Please help!!!
See below
Look at your data usage, good chance that's the originator of the wake lock. I had picasa do that on aosp and tw. It doesn't usually directly show up. But the data usage is how I found it. On tw smdexe can also cause a wake lock with no direct flag

GPS is on. This would be normal. Your phone constantly polls your location unless you turn it off. Having GPS on only worsens that effect but you get better location pings.

I think it's your signal bud. I didn't see anything out of the norm for wakelocks with exception of suspend backoff but that could be anything. I see that your phone has no signal for 99% of your wake time. Since you're saying both your wife's phone and yours are the same I would charge both up, put yours in airplane mode but keep the wifi on and test em. That's the only thing off that I noticed. A few guys have been working hard for battery life on another thread here. I'll link it to ya if you want. That's what I would do anyway, just to rule it out. Your mmc detects are high too and I haven't been able to verify this but I think that has to do with accessing the external SD card.

Any ways to save battery other than settings?

I really like how my settings are. Sync settings are minimal...but its been off the charger for 3.5 hours with moderate use and its at 76%....im looking for how to undervolt (not underclock) or any battery saving tweaks.
Also...im on synergy rom and cant change the setting so there is no LTE..why? And quck question...is there a key strock to get to recovery...new here
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Turn off the Location access, and dim the screen as much as you like... I just got 36hrs with 3hr screen time with only those changes... To undervolt, you need to be running a custom kernel, and use a tool like SetCPU, Voltage Control, or KTweaker if the kernel is KT... To get into recovery, use the advanced power menu, or while it's off, Vol Up + Home + Power... Check your APN settings for LTE...
I've found that undervolting is a pain, and doesn't save me anymore battery than stock voltages... Mess around with it and decide...

I'm sure it has some sort of battery use, it's always looking for motion... Whether turning it off or not will help a noticeable amount, I'm really not sure, it's a TouchWiz feature, I haven't ran a TouchWiz ROM the entire life of my phone...
Any TouchWiz junkies out there who have noticed a difference turning it off?
find and eliminate wake locks. disable bloat apps. run a good light rom with battery saving kernal. turn off what you dont need. thats all really. if your battery is dying fast find whats keeping your phonw awake and do something about it. I can go to bed with phone at 100 and wake up 8 hours later at 99. also go to bed 50 and wake up 49 etc. you should expect the same. on 3g I get at least 5 hours of screen if im heavily using all day. but battery life is up to you. you want to be minimalist like me you can expect similar results.

find and eliminate wake locks. disable bloat apps. run a good light rom with battery saving kernal. turn off what you dont need. thats all really. if your battery is dying fast find whats keeping your phonw awake and do something about it.

Is this all GS3s? Or should I flash back to stock and get a new one?

You can dial *#0011# then hit Menu > Wi-Fi Settings and make sure the WiFi sleep policy is enabled. Every time your phone sleeps, WiFi is disabled and you have to reconnect, but it does help on battery life.

I dont think it does. uses battery to turn on and off the wifi. just leave it on. ny rom is wicked v8 and intergalactic 2.5 kernal. weird combo I guess. but it just works for now
I squeezed 7 hours display (18+ hours standby) on a single charge with auto brightness on and LTE and sync on all the time. Routinely I get 5+. I would say, get a good rom n kernel combination (only way to know is to try out).
Are you using Google+ and/or facebook?
