[Q] Heat issue and uber fast battery drain - Epic 4G Q&A, Help & Troubleshooting

Hi
got an EPIC 4G
it heats up excruciatingly while charging , especially from top back area
also no matter its a new or old battery , any modem , kernel or rom , the phone drains like anything , a fully charged battery drains sitting idle within in 4 hrs
bought it off ebay for a friend whose epic i had bricked

Mines was the same way. Mine even drained when the power was OFF. Some things I noticed is that on wifi, it drains less. When not on wifi, if I have a weak signal, it gets warm and drains like nobody's business (4hrs like yours). Turn off 4G. Turn off bluetooth when not in use. Make sure the gps is not on. Some people say that this doesnt matter because the gps will come on only when needed, but I noticed a difference. Stop some of your programs / apps from running in background, or stop them from booting at start if you dont use them much (do this with ALL IN ONE TOOLBOX on PlayStore). Lastly, let the battery go through a full discharge a couple of times... this is all that I can think of as of now. HTH.

Just my 2 cents, but it seems like my phone heats up more when on stock and cm7, compared to cm10.1. Heat issues and battery drain virtually gone on cm10.1, but a pesky random reboot bug that I can't figure out.
What rom are you running, and are you using a 3rd party battery?

On average, how much battery percentage per hour?

Just wondering how much your battery goes down per hour? Seems like my battery is getting worse. So I was interested to see how your battery is. Im talking little use. No 4g on. I went from 99% to 89%. I downloaded one app.
Im running stock kernal doexed with cwm and thats it. No roms or anything.
Phones pretty new but I get 10% hour on epic4g with an extended battery, but that's for like the first 20% after that it moves like a snail. Basic battery saving techniques are applicable across all androids so any that you may find should help. Screen brightness has been the cause of me losing hours before so keep it low!

Let's Go NYG NYJ
I unplug my phone every morning at 5 am when the alarm goes off. use it all day until I plug it back in around 7 pm and rarely has it ever been close to 30%. Just sitting there with the screen off and nothing running I probably only lose about 2 % an hour but i use the phone a lot and haven't had a day that I haven't been amazed by the longevity of this device. The only time I had a battery drain issue it was caused by an App I had downloaded. Once that was removed it's never been an issue since. Misbehaving apps are something most people don't look at and instead blame the phone.

This is so true, right away people say it's the phone's fault.
It's hard to say, because I'm afflicted with the "Android OS" bug and it took up 50% over 8 hours (6.25%/hr) while I was sleeping. However, when I"m actually using it, I'm seeing 10-13%/hr on 3G with good signal.

Excessive Battery Drain

My Desire Z has been a battery killer recently. I have tried different radios and roms and it still sucks excessive power. Even on Airplane mode battery monitor widget was giving ~50mah per hour drain with the screen off.
I have both a stock battery and a Mugen 1800ma battery and this seems excessive. I checked and there were no applications keeping the phone awake either. At work with minimal usage my phone easily drains over 30% of the Mugen battery. Signal isn't a problem either because I work 280 metres away from a Bell cell tower and have full signal at work all the time. I'm starting to think that something is wrong with my phone.

I had a similar problem with a stock battery of mine and ended up recalling it with my phone provider and they shipped me a new one. They (T-Mobile) said "not all batteries were created equal" and that sometimes even without water-damage, certain batteries lose their shelf-life much faster than others.
Since you're telling us that both your stock and your after-market are draining at a near equal pace regardless, this might be an indicator that it isn't your battery.
I had to return my original G2 to T-Mobile because of hardware malfunctioning in several areas, namely the audio mechanisms. If you're using a relatively new phone, and/or a refurbished phone, I wouldn't be surprised if you are experiencing similar problems.
Omg, recently, mines been really bad too. Trying to get to the bottom of it.

I'm starting to suspect a hardware problem on mine. I don't overclock at all. I've tried different roms, kernels and radios and it hasn't helped...

I had fast battery drain too, I switched to the ROM in this thread, and battery life is now AMAZING
use SuperWipeG2(+) and Guhl's EFS GPS fix available here before flashing G-lite
Have you tried calibrating? Charging to full, wiping batt stats, discharging/charging back to full uninterrupted? The link below is a great calibration tool.... very convenient. I wipe stats after every ROM flash and keep an eye on CPU/RAM usage with Watchdog lite. Battery life is always good.

how long does the battery last for aprox in standby and with regular use. if it dies faster then 3days on standby or less then a day with regular use there may be an issue im just wanting to know the time span of your battery....
also i had hardware issues with the g2 too. my radio sucked balls, i couldnt even keep signal in a call longer then 3 seconds and my wifi would just cut out for periods of hours at a time... im wondering if the manufacturing is becoming sloppy and they might be lacking quality control. i admit there is a lot to the phone but simple things like battery quality and signal quality should be checked regularly.
with the g2 i frequently hear things like this, battery, screen failures or behind the screen cracks, unresponsive touch screen and black spots, bad radio signals, color leakage and most commonly issues with the keyboard.

Well if battery monitor widget is correct my phone would last 26 hours in airplane mode (36 with my mugen battery) with the screen off (I tested this with almost every user app uninstalled)
Edit:
Considering there was a guy who left his old Hero with CM7 in airplane mode and that it lasted for 30 days before the battery died... I find this quite discouraging

Wow. Battery monitor widget is INCREDIBLY innacurate while in airplane mode. I left my phone in it for a good 10 hours and it was still at 100%

4G Battery Drain

Hey, im on Telus so i dont have any other modes I can switch to to lower the drain. Ive noticed my battery drain is HORRENDOUS
Over the past 4 hours ive dropped 60%!
Now im wondering if im just running too many apps or if my stock battery may not be holding a proper charge anymore, and wanted to compare with others to see if others are running the same amount of apps and getting better battery or what
Ive got the following on:
Trillian (IM app)
K9-mail checking 2 aps
Regular Sync (Twitter, FB, Dropbox, Google(Calendar, Gmail, Contacts)
The battery usage summary seems to lie, 35% is the screen but only 13 minutes. Yet im at 40%
Android System at 20, Cell standby 13, Phone Idle 8
While heading to work, i ran DI Radio(music streaming), and lost 20% over around 35 minutes.
Im using the Tuesday rom with it's default kernel.
Is there anything I can do for better battery, because I dont have wifi in most places, and im running 3-4 bars constantly yet the phone just drains rentelessly. Even my Mugen battery was only lasting 16 hours...
It's quite possible that it's the ROM. I used to always get 8 hours on a single charge, regardless of location or ROM. I'm running Eugene's CM7 and I'm getting 13 hours on the same typical usage.
I'm running on Telus as well, with no wifi at all.
Although I am not running all of your apps, I would still consider myself a moderate to heavy user.

Its been a while since ive run juggernaut. But it used to only drain 10% an hour i believe on 4g. I've restored my nandroid of Jugg and will be monitoring that.

any syncing or usage of the network will take a drain. any usage.
you can always turn on airplane mode and let it sit a few hours and see the drain, that determines whether its network or a ROM/kernel drain.
But yes, using 4G has big battery cost
Battery Life
I will tell you what, I have wasted so many hours playing with different ROM's and what not to find the one with the best battery life. And I will tell you what, the DARKSIDE:IGITAL::WARFARE ROM's out do any other ROM out there. I dunno what it is that thederekjay is doing, but Samsung should get this guy on pay roll because his work is the best.
I'm at hour 8 today on Darkside Digital Warfare, and 70% free from 8am to 4:30pm. I have push corporate email, automatic brightness, friendcaster push, and a slew of accounts and it runs like a champ with amazing battery.
Make sure your phone is going into Deep Sleep as often as possible when screen is off. My phone seems to be extremely picky in regards to which charger it likes and more often than not (even had this happen on the stock charger) the phone refuses to sleep after being charged (even if only for a few seconds...).
Download CPUSpy from the market and after each charge, go to CPUSpy, press menu and Reset Totals (phone cannot enter Deep Sleep during charging so it's important you start fresh after a charge to get accurate sleep time). Turn the screen off for a minute or two and turn it back on. Press menu again and Refresh Totals. In my experience, if the phone is not sleeping at this point - Deep Sleep showing in Unused States - then it will not sleep all day and remain in 384Mhz for hours, killing the battery rather quickly. From then, if I plug the phone in a supported charger (even for a second) and disconnect, Deep Sleep resumes normally. Rebooting always fixes it too.
If, like me, a lot of people also have this problem with the stock charger as well, I bet many are dissatisfied with the battery performance... The phone is supposed to spend the majority of it's time in Deep Sleep. I get this issue with several different chargers and cables and on different ROMS / kernels (including stock... go figure).
Im pretty sure its the signal itself draining it. It uses sleep for at least 40% of the time its on. I use my phone a good amount, but its the fact that if it sits on 4g even with the screen of, its rapidly draining during this time. ive even reset timers and left it sitting for an hour and itll be in sleep but lose 8% over an hour just doing nothing. I still wanna be able to recieve notifications tho so turning off data isnt an option. I will test turning off data anyways to see if the drain stops.
The battery drain is all those persistent internet apps running. That is what you call heavy usage. Trillian and the FB app being the two biggest. Music streaming would be up there as well if you aren't in good signal area. Look at your battery stats and see what your signal strength is.

For those with battery issues.

Leave ICS and get back on GB.
Ive had this phone since the day it came out. Switched to ICS once the developers started dropping ICS leaks, etc.
For the past 2 weeks for some reason, Ive had nothing but HORRIBLE and i mean HORRIBLE battery life. Phone would not last me more than 4-5 hours of heavy use. I'd have to carry around my portable battery pack to charge the phone on the go. I did everything to my knowledge to try and conserve battery life. CPU tweaks, battery monitoring, tried different ROMs, Kernels, Modems, etc, etc. Nothing would significantly improve battery life. I even went ahead and ordered a new battery last week to remedy this problem (which has not yet been delivered/used)
2 Days ago I flashed back to Blazer 4.0 ROM (GB).
I unplugged my phone yesterday morning at exactly 7:30am. Did not step back into my house until 530 which at that point I was at 35% and had been using my phone all day as I normally would. Web browsing, tons of texts, Used Navigation for about 2 hours, etc. I did not plug my phone to the charger until 10pm. Phone was on 19% then. Mind you, this is on the first day of the Phone being on a new ROM/GB so the battery has not yet settled/calibrated as Its only been charged Once since flashing over.
I refuse to switch back to ICS for the sole reason that battery levels have obviously improved with something as simple as switching back to GB.
Just a heads up for anyone with ICS on their E4GT having issues with battery life.
If only I got a dollar for all the times a thread like this is made.. I'd be rich. Blah blah ICS sucks yes we know... So far my phone must be a super phone because it's handling ICS well.

I agree with you, Ray. I'd also be rich for every time I've read of E4GT owners who's phones are running ICS with no problems. But then theres the bunch who also complain that they have problems. I never stated ICS sucks. At this point these phones are old by today's standards. Be glad you're one of the ones who's running ICS with no issues. I for one will stay on GB until I switch to a new carrier/new hardware sometime soon.
Just thought I'd give some feedback of my experience with battery issues on ICS in comparison to then switching back to GB.
I don't know if you've tried Blazers ICS ROM, but that thing has some AMAZING battery life. I've been running it for a few weeks now, everyday I get at least 12 hours of moderate to heavy use, without my own tweaks, and by the time I connect to charger I'm at 35%
Arguments apart
i have a few friends all on this or that ICS and none of them is happy with the backup
whatever its a fact ICS goodness never really reached E4GT, lets hope FI03 onwards some sense prevails at those losers at sammy and they push something which we can smile about.
FYI i am also on ICS Rom , still in testing phase after getting my new white beast 10 days back , already tried like 3 , each for three days
running galaxy 1.8 since yday and hoping it shapes well otherwise i ll also move back to GB
I've tried multiple ICS rooms and I've always gotten great battery life (14+ hours with 3+ hours screen on time).
The only times I've ever had battery life issues were when a certain app was the culprit and was keeping my phone from deep sleep or causing frequent wakes, which is almost always the case with poor battery life issues.
Check out an app called GSAM Battery.. it will tell you what is using up your battery in easy to read graphs and percentages. Also, check out CPU Spy to see if your phone is actually going to deep sleep mode when you turn your screen off--again, it shows you in an easy to read chart with times in each state.

I got over 30 hours last weekend with light use, but the next day, my battery would drain 5 to 10 percent per hour with no use. I have all the utilities to track what's happening, but cannot find a definitive cause. Poor reception seems to be a factor, but not the whole story.
EDIT: I just installed GSam. Thanks for the tip!
Try the Re-Calked FI03 and tell me ICS sucks....this things is as good if not better than Calkulins v3 GB rom....the ONLY other rom i have ever liked.... :good:

Maybe you should've posted this after receiving and using your new battery. My phone had horrible battery life after a while on ICS but it turned out that it was in fact the battery and not ICS. Got a new battery and it is back to 18 hours a day (on ICS)

Only the stock ICS rom is garbage with poor battery life and stupid stuff like grey text on black back ground. I have ran several custom ROMs and they all provided better battery life. As I have said before, I got 99 problems but battery life ain't one of them. You must be doing it wrong.

Still waiting for the new battery to arrive. I would love to try it but I'm in the midst of a heavy usage of Verizon PRL on my phone. Sprint doesn't like heavy roaming users from what I've been reading. Sprint 3G in my neighborhood here in NYC sucks Donkey nuts. I can cross the street and get 3 bars more than I have sitting on my front porch. But thats a whole other topic of discussion.
Im not sure why my phone couldnt play well with ICS but it really was horrible. I consider myself a heavy user and ICS couldnt keep up with battery demands. I tried undervolting, etc. Oh well. Been eyeing the SGS3 or the upcoming SGNote 2. Time will tell.
So far 3 days on Blazer 4.0. All my apps are restored via TB and no issues with battery like I had on ICS. Don't really know what else to say. :good:

I'm getting 24+ hours on standby time. I have gotten about 18 hours with about 3 hours of screen time. Facebook and GBA emus. I wasn't able to do this since GB. I have done this by doing one simple thing. Turning off data. I kid you not. Utilize that data toggle. I know at first you're thinking no I need data. But you don't. Unless you're some business person, then this excludes you. Wanna check Facebook?
Also, wii benefit from something else. 4G WiMax. You can turn that on even though your data is off. You still get decent battery life since 4GWiMx knows how to sleep. Also, if you're driving around, it'll pick up 4G eventually (unless you don't have it) and it'll download what it needs to download. So by time it turns loses signal, you'll have your emails. I tried this and I still got good battery life.
Using Battery Monitor Widget, I was able to see that my phone wasn't "sleeping". That's what the main problem was. That's why I wasn't able to find any rogue apps using Better Battery Stats. But I did see my phone stayed awake. Like once my phone died in 5 hours. 10 minutes screen time. 6 minutes of deep sleep. Really? That means my phone was awake for over 4 hours!? Doing what!? No app was at fault.
Extra stuff. No need to read if you felt you read enough
An app you all should check out...
https://play.google.com/store/apps/...av_result#?t=W251bGwsMSwxLDMsImNjYzcxLmJtdyJd
Battery Monitor Widget (It's not just a widget. LoL!!)
It tells you how many #mA your phone is using. So if it shows 500mA. That means your phone is using 500mA per hour. Your phone has an 1800mA battery. So that means if your phone used a constant 500mA, it would die in 3.5 hours. This is a good way to see just how much power your apps are using, or if after 10 minutes your phone is actually sleeping. My phone actually started using 2mA. I haven't seen that since GB. I thought my phone would never sleep like that again. I cried.
P.S. If you get the app, in settings -> Calibration, change the battery amount from 1500mA to 1800mA. Apparently the app thinks our battery is 1500mA. Or maybe my battery REALLY IS 1500mA. I mean, it got my Nexus 7 battery correct. I didn't have to change it. I've always wondered why BMW said I had a 1500mA battery instead of 1800mA. I may have to look into. Wii all should probably look into that.
Also, those on Blazer ICS ROM. Using BMW, I was able to see something quite interesting. My phone would use a lot of energy. Like 1000mA just to send some text messages, or scroll through my app drawer. BUT, after I stopped using my phone for about 10 minutes, I'd turn it back on and BMW would show my phone gaining #mA, or charging. This means something is causing the phone to "drain", or show drainage, when there really isn't. The fact that the phone charges back means it never really used that much energy in the 1st place. But that only happens on this ROM. Since I figured out the data thing, I'm going to try CM9 again.

Galaxy Nexus Horrible battery

hi guys,
sorry i'm noob and this is second time im posting on xda forum. I recently bought a Galaxy Nexus Made in korea by samsung. It's currently running on 4.3 latest update phone doesn't lagg or nothing happend like crashes etc but please see below major problems im facing.
Phone getting hotter from back side where camera is installed
0 to 100% it take 5-7 hours to charge ( I tried both wall and USB)
I charged the phone to 100% in night and i didn't use the phone night in morning when i check the phone the batter was at only 12% left. the phone eat all the battery in 7 hours the most battery was used by phone idle 57% and stand by 33% & i didn't put any sim card in the phone whole night and automatic wifi was on which was only 17% battery.
again i charged the phone to 100% close the automatic wifi and insert a sim card
The result is like
After 3 hours 57 mins battery was at 52%
Screen take 49% total screen on time 16m 1s
Phone Idle 22% 3h 41m 29s
cell stand by 10% 3h 54m 55s
Android system 5% (CPU TOTAL 1m 47s *** CPU foreground 33s *** Keep awake 1m 19s)
I don't know what was the battery time before 4.3 update becuz when i buy this set it came with 4.3 and i bought this 3 days ago. Is this a battery problem or the phone problem or its the android ???? any type of help is welcome
Thanks in advance
The Galaxy Nexus is known for its not so great battery. It also just depends on how you use it. If you are playing games, watching videos, etc. it will drain fast. If you just check a few things here and there, it will last longer. That's common sense. But yes, compared to other phones, the Galaxy Nexus sucks with battery. Theres not much you can really do software wise. The best thing you can do is get a bigger battery or a spare battery. I have a charger pretty much wherever I am so battery isnt an issue for me. But if you are someone who is on the move all day, I would suggest a spare or an extended battery.
EDIT: Actually, looking at your screen time, you are getting a bit above average on phone idle. Right now, my phone idle is at 8%

Yes i read that and i planned to get extended battery but the cell eating the battery while screen is off. I'm just confused about the OS 4.3 i read alot about that after updating to 4.3 nexus 7 user experiencing of slow charging and battery draining but as you seen in attached pic the phone eating battery without any usage the total on screen time is 6 min and in 3hrs 57 min 48% battery gone ?? so in your opinion what is the prob is it OS, phone or the battery ?

Well I see in your screenshots that it looks like you don't have any cell service. What could be happening is that your phone is constantly searching for a connection, which could eat up a lot of battery.

youre best bet if rooted and unlocked is to install a custon kernel and underclock it to about 1000 mhz ... install dark themed apps or theme chooser theme also us a black wallpaper .. turn off 4g . ... turn off nfc when not in use .. make sure youre using the oem charger to charge the battery .. use wifi whenever possible .. also turn off anything like hotword detection that is constantly listening

The mobile service was on but data service was disable i received 2 calls and some texts msgs 2 but they are not long or didn't took the battery. All syncs were off and location to. But the battery is going down very badly. Please see new attached files of last night. The cell was at 87% battery and in the morning the battery was dead.
Try using something like Better Battery Stats or GSAM and see what they say is draining your battery.
With the current info given, I would lean toward thinking it is a hardware issue. Perhaps your battery doesn't properly hold a charge anymore.

Few hours ago i left for office the cell was on 14% charging and turn-off the cell and put it in pocket. After 1 hour when i reach to office i was trying to turn on the cell but the battery was dead and then i put it on charging and it start from 6% and turned on. I think the battery is not holding charging . The battery is in made in Korea and have NFC details on it. I think its the original battery but its not use able any more. i will try above mentioned widgets before changing the battery.
new screen shots
didn't use the phone and it ate all battery. Any guesses what's wrong with the phone???
need a fast reply.
Try updating the radios (I don't remember how to do it. U dial #something). Also, have gps and 4g turned off. Auto brightness turned on. If u have the Facebook app, get rid of it and just use the mobile site.

4g/3g are off and i ticked use only 2G network. Facebook app is deleted brightness is set to auto GPS every thing is off but mobile consuming battery without any usage.... im just confuse about that its the hardware prob or i have to flash some other rom?
bump! any 1 with solution ?
U really need to get better battery stats. It will tell u specifically what wake locks r causing the problem. Idk if using only 2g is a good idea, u may be burning battery with apps constantly searching for a data connection. Can u access wifi? That takes up less battery than data (3g or 4g). U may want to buy a new battery, they aren't that expensive. U can get one on amazon for like $15. If that doesn't work, I'd try flashing a different rom, maybe even a custom kernel.
I am still running 4.1.2 because I like it better than the newer versions and my battery life isn't bad. I usually get close to 2.5hrs of screen on time. More than a day of standby. Obviously, if I make a lot of calls I will get less battery life. I'm running eclipse rom with leankernel.

Today i flashed Cyanogen mode 10.1.3. i didnt flashed any google apps just to check what eat battery. When i flashed the ROM the battery was at 36%. I used the mobile for almost 1 hour and on screen time was 54min 37sec and battery left 16%. The cell eat total 20% battery in 1 hour continues on without mobile data network and 2G was on. Wifi GPS every thing was off and brightness was set to auto. At 16% battery i stop using mobile and after 30 mins i check mobile it eat 6% battery in 30 min without any usage. then i truns off the phone and after 30 mins i tried to turn on the cell the battery was dead. then i plugged in the charger and i turn the cell on. The battery charge start from 10% but instead of charging i start loosing battery. then i charged for almost 1 hour on 0% battery and took 5 hours to fully charged. My cell phone drain all battery over night under the usage of phone idle 73%. I'm just confuse about that its the battery issue or its cell phone problem. and my phone getting very hot from back left side. I just need a good developer advise if this is hardware issue then i'm gonna replace the cell phone and if its the battery issue and hardware is ok then i will get a new battery and continue using and 1 more thing my phone get little hot even its turned off from back left side and sim jacket side.
Bump! any suggestion ?
I doubt a developer can answer that question. Could be phone, could be battery. I would try a, new battery just cuz it's cheaper than a new phone. Maybe go back to stock and see if that helps. If not, call Verizon and complain, they may send u a refurbished unit.

Try going to 4.3 via fastboot. With the flash-all.bat that will wipe everything. That might solve it
