What is up with my battery? - Epic 4G Q&A, Help & Troubleshooting

I'm a new Epic owner, still learning the quirks of this phone. I am having issues with my battery giving me a proper charge. I need a reliable GPS for a 3,000 mile road trip coming up, and this phone is all I got... so it needs to work. My issue is that the phone never seems to know how much battery it really has, and often appears to loose battery even while charging, but I'm not convinced that it actually is. So I did a little test. Went on a 15 drive, everything off except for GPS. Played music through the phone, and had the nav up the whole time, with the phone charging.
Started at 70% battery. After getting to my destination in 15 minutes, I was at 64%.
I rebooted my phone, and when it came back up, the battery was at 24%. I did some shopping, and texted my wife pretty much the whole time, phone stayed at 24% for the entire trip.
Rebooted again when I got back to the car, and it jumped up to 36%. Same deal on the ride home, music + nav up for a 15 minute ride. It was still at 36% percent this time when I got home.
So, what's with all the inconsistency here? Is this normal? Should I get a new battery? I'm running SFR 1.2 with Genocide kernel, 200-1000 conservative, and everything undervolted slightly.

Have you tried fully charging your battery and wiping the battery stats through Clockworks? Also I'll have to do some digging but if I remember correctly the reboot thing is a known bug. I believe they said it has something to do with the reboot script. I'll see if I can dig up the link for ya.

I've wiped battery stats between flashes, but not recently, and not on a full charge. I will try this.

Let us know how it goes, so I can try it.

Well after doing that, my battery life yesterday was probably the longest it's ever been with this phone. Next time I go out, I'll throw it on the car charger again and see if it still drains while using it.

Yeah the proper way to calibrate it is by charging it fully first after a successful flash and then wiping the stats. I usually do a full charge with it on then turn it off and wait til it fully charges again (led turns blue) then boot into CWM and wipe its stats.

No luck, tried it out yesterday and got the same thing... battery drains while on the car charger (tried two chargers). Also get the jumps in % when rebooting, but only sometimes.
I ordered an extended battery for now, hopefully it will do the trick to get me through my move.

It's not an answer likely to make you happy, but the type of car charger you use and the car's electrical output are a factor here. I have personally seen a large difference in recharge time and ability depending on those factors. It may be worth your while to gamble on another $15-30 for a well-reviewed charger. It's definitely made a difference for me.

That's what I did. I had a cheap charger, and it didn't work well so I dropped $20 on a Griffin one, and it was no better. I never had a problem keeping my HD2 or Nexus S 4G.
Also, just for ****s, had the phone on a wall charger and made sure to keep the screen alive texting and playing WF... slowly but surely the battery drained while on the charger. So, not my car either. Seems like the screen being on absolutely murders my battery.

Sounds like a pretty scientific review, so that result sucks. However I would actually now throw some suspicion on your battery and/or phone itself. Reason I say so is that I am a heavy phone user at my office and also have screen awake and a lot of use for music and video playing and 4G audio streaming while on wall charger, and consistently get into the upper 90s or full charge while using it so much. See if Sprint will throw a new battery your way, and maybe that will help?

We'll see how the extended battery I ordered does.
I didn't get the phone subsidized through Sprint, so it has no warranty. I doubt they would help me.

Download Spareparts and see if there are any processes hogging the system, especially in the partial wake lock list. It very well could be a faulty battery although I can't recall anyone ever having a battery issue on this board.

Nope, doesn't look like it.

BTW, I am running rooted stock EC05, no other mods except some frozen apps and Roam Control. I wouldn't wager that necessarily makes the difference, but you never know.

Try a different kernel?
You may want to start fresh and Odin back to stock and reroot.

I experienced this on both the kernel that comes with SFR, and Genocide.
I may go back to a rooted stock... but I have been really happy with every other aspect of this rom.

You might want to Odin and start over. The only thing I can think of is maybe something is wonky with the modem or something.

I have one more thing to try first.
I've been using Launcher 7. There are lots of complaints about this being a battery hog. Going to give things a shot with ADW and see how I do.

Never heard of Launcher 7. I've seen ADW on the Market, but never tried it. I've used TouchWiz when I first got my phone, but lost it when I rooted with SFR. I am using LauncherPro right now, so try that one.
Also, I read that GPS is a major battery drain for smartphone. I never had a problem using GPS on my Exclaim, so maybe its the GPS drinking up a lot of the battery fluid?
Tbh, you should not worry if your vehicle has an adapter (either itself or cig lighter) and plug it in when the battery goes low.

Launcher 7 mimics WP7. I'm all for a clean, simple look, and as such, really like it. But its a CPU hog.
ADW is wonderful, and for most of my time with android its all i've used. I've got the paid version. Went ahead and installed it, and so far, so good. Setting it up with my phone on a charger, and my battery is finally going in the right direction while using the phone
I'll go for a drive somewhere tomorrow and see if it charges in the car while running ADW.

Battery Question (NOT a complaint, for once)

Hey all
So I, personally, don't have such an issue with the battery like other people. I'm coming from a near 2-year old G1, and i think the battery life and performance on the EVO is better, so i'm generally cool on this front.
But here's my curiosity question...
I'll charge up this badboy to 100% overnight.
When i take it off the charger, it dips down from 100% to about 95% in a matter of about 5 minutes.
After that, it's cool and lasts a while, so it evens everything out for me.
But i'm just curious as to why i have an almost instant 5% drop when i take it off the charger? Where does the 5% instantly go?
The Evo isn't topping the battery off, that's all.
I think I *might* know a solution, I believe I saw the phone stores battery "calibration" or something like that. I'll look into it eventually.
I had the same problem until I tried the trick I found here http://forum.xda-developers.com/showthread.php?t=701567
After doing this my battery doesn't plunge when I take it off the charger, the only thing im not sure about is how often this trick needs to be done, hope that helps.

Evo dead - not booting up - no recovery -- brick?

Hi guys... I was running MIUI the April 29th/30th build or something. Stock everything.
Today when I was charging it... I started charging my Evo at 8% and it was stuck at 8% for quite some time and it still said "charging."
Then it died and I tried another charger. I would press the power button and the white Evo screen would flash for a second and then die.
Tried another charger and same thing.
Now I can't even get the white Evo screen to flash and nothing happens when I press the power button.
The phone isn't charging and it won't even boot up with or without the battery in there.
I can't get to recovery/bootloader... or anything.
Does this have anything to do with the CM7 problem a while ago? Any simple fix?
This is the only time I've ever had problems.
Sounds like your battery died. I would try a new battery before anything else.
Dude that sucks hope it was just your battery a bad one. Running SBC kernels can spank a battery if you were a heavy user nothing to worry about tho batterys are cheap to replace. Some people have issue like that from not wiping right when flashing kernels such as SBC ones and copying over the other one without wiping.
Plus I seen someone else have this issue using miui on there forum. I have no idea what it is but people been trying not to freak about it.
It could be your battery or your charging port - if it's either of those, a fully charged battery should boot you up. You most likely still have a recovery, you just can't get to it because you don't have enough power. If you were charging from a computer, try charging from the wall instead.
If it's your usb port, Sprint should replace your phone for free if you have insurance. I'm not sure of the policy without insurance, as they seem to keep changing stuff like that.
My Evo + xda Premium App = This post.
Thanks for the replies guys.
I'm hoping it's a battery thing. Someone elsewhere said that a battery boost was needed because the battery is completely dead or something. I'll just go to Sprint tomorrow and check it out.

If you were charging through the computer, the phone could've discharged faster than it was charging. I bought an external charger and three backup batteries on ebay for about $11 with free shipping. It took a couple weeks for it to get here, but I'd suggest getting something similar. I charge my batteries in the external charger and just swap them out when they get low. Now I really get to use my phone & not worry about battery life

Yeah... I remember that deal. I didn't really think I'd need it, but now I wish I jumped on board.
Also, would it hurt if I change chargers? I left my main charger elsewhere and used some spare chargers that my friend and I had. Those didn't work.
Either way, I'll see if it's the charging port or the battery. Hopefully it's the battery.
Luckily I can send/receive texts through sprint's website. I'll have to do that to communicate tomorrow.
I just went to Sprint and got my battery boosted. It works now.... incase anyone else runs into this problem.
I'm sorta' blaming the SBC kernels...
It's NOT the SBC Kernels. Even HTC recommends not draining the battery fully and says wait til you're below 50% to recharge.
thousands and thousands of people use SBC kernels with no problems. Just because you're in the >1% that has a problem and happens to have an SBC kernel doesn't mean it's the kernel's fault.

I did drain the battery fully... then it died completely.
However, I probably shouldn't have pointed fingers to the SBC kernels. I've just heard of other cases on XDA with a similar problem and I may have been quick to accuse.
I doubt it was SBC, it's fairly common for the battery to get moody over being drained completely.
I blame mass hysteria for you blaming SBC kernels. Glad you're back up & running

That draining the battery thing = bad!
Great
So glad it was just a battery issue!
I seem to be in the same boat. I guess I'll bring my battery to sprint asap and see what's the deal. I'll post my reply to tell you what happens but basically the samething has happened to me
Edit 30 mins Later :
I got to the show and it wasnt the one that did the repairs but they said this is really common and refered me to a spot in the city. Gonna head there a bit later and tell you the results

battery on fire

Been Runin kingdom for weeks now had no issues til yesterday my battery started burning up the entire back of my evolution is very hot and i only get bout an our of life. I uninstalled all resent apps and haven't changed the way i charge the batteries. Any idea wnat's goin oh?
Your battery is fried.
it could be the kernel u used. I heard some cases where the sbc kernels were making the batteries smoke and basically garbage after that

I got a good laugh out of that.
Though, if you were using an sbc kernel, guilt right there; or your battery is toast.
Love the stupid replies but its not the kernel i use a battery wall charger i never charge via USB
did you ever let the battery fully discharge?
i killed a Li-on battery on a laptop by always plugging it in and never letting it discharge.
now it only lasts about 10 minutes and dies when i unplug it.
Usually let it discharge to about 6% its multiple batteries and just started happening.

Well the appropriate percentage to discharge is 5% because anything prior will only make your battery burn up and make the back plate hot and only give you 10 minute battery left thereafter. - see this explains all. close thread please.
Okay, so what it really sounds like is a case of a bad battery. Sometimes you just get those and you are the lucky person at that.
The mention about SBC kernels and the battery issues were even case-by-case at that. There were no proven conclusions but only hypothetical scenarios at best. I'm not discrediting ones who experienced it but just channeling logic.
For your matter, you do realize that the Kingdom ROM is never going to be 100% stable, as mentioned in the OP, so there could have been a freak instance of it not agreeing with your phone. The inevitable truth is that even if you and I have the same phone, same hardware, there are still small differences in parts sometimes and even those make one ROM or kernel agree and disagree with each of our own.
In short, I believe that it's best to go buy another battery in this case since it just sounds like you're going to need one anyways. As for the cause, it's hard to say because none of us really know your entire hardware build, kernel, applications used, and any other variables that could have caused this.
Here's a link to a ebay listing for batteries:

If ur using a SBC kernel it doesn't matter how u charge ur phone. It would happen with wall charger or computer charge
Kool-aid anyone? I hope you people realize that the Kingdom ROM does not have SBC. Also that the hottest running components are right under the battery. Just from what the Op posted it sounds like the phone is heating up off the charger, and getting only a hour of battery life.
A number of things could cause the overheating condition. From an app grabbing the CPU and locking it at 100% to having the 4G radio on in a no-signal condition. The battery will also get very hot if it has a high load put on it as well again pointing to something other than SBC going awry. I would suggest that the Op do a complete wipe, and reinstall the ROM. Then install Battery Monitor, OS Monitor, and SeePU (to monitor the CPU activity).
Battery Monitor can keep track on how your battery is being used as well as the battery temp(and you can set a high temp alarm as well). SeePU monitors CPU, and network usage in real time. OSMonitor is a process monitor (much like top/kill in *nix, or TaskManager in Windows) so you can see, and kill off a runaway process.
Hopefully this is a bit more helpful.

[Q] Can't get a full charge!

Hey Folks, Just wondering if there are any other G2 users out there that have experienced this. For some time, I haven't been able to get my phone charges fully, and by fully, I mean something close to the reported norm of 97%-100%.
The hightest I got my phone was to 81% and that with a new battery, recalibration, and bump charging. In fact, I've had the phone powered off over night and upon restarting it, it was at 71%.
I've watched logcat to see if anything could be an issue there, I've installed ZDBox, (cool app, btw), and Battery Dr. The good news, is that after uninstalling a few apps and widgets, my battery life seems prolonged, (relatively speaking).
I'm running CM-7.1.0-RC1, 2.6.32.41-cyangenmod pershoot, and using the 26.06.2.27_M radio.
Since I couldn't get a full charge with it powered off, I'm thinking it might be a hardware issue or maybe the radio since so I might try 26.08.04.30 radio. Googling other forums, people were able to get a replacement phone from T-Mobile and some others said their motherboard needed to be replaced.
Any other ideas before I call T-Mobile?
Thanks!
Did you try clearing battery stats?

Have you tried reflashing the rom? Maybe trying a different rom? Clear caches? I dunno I'm shooting for broke i guess....is it an aftermarket battery or stock?

Thanks, killj0y. Yes. I did that after posting. I did a Titanium Backup, then Nandroid backup, then wipe, superwipe, then flashed the CM7 nightly, (which is very slick, i might add). After bump charging I was able to get it up to 71%. I let it go down to 0% overnight and now I'm letting it recharge fully.
In about an hour, I'm going to call T-mobile and see if they have any other ideas.
It is an aftermarket battery but it behaves just like the OEM/stock.
You shouldn't ever drain your battery to 0% on purpose. You run the risk of the battery not being able to take a charge. Draining to 20% for battery meter calibration purposes is more than sufficient.
Yea plus aftermarket batteries can and do fail more often than stock. What brands is it?
Do you still have your stock battery? Try using that one and see how it acts. I'm willing to bet it's the battery.
The OEM battery I could never get above 71% and the new battery I have it up to 94% now and it isn't charging any higher.
I've had it plugged in for two hours. I have read the warnings about letting the battery drop to 0% and I agree, but I figure one time wouldn't hurt it. I got the second battery, thinking it was a problem with the OEM battery.
Ah! This happened as I was typing this. For the first time in a long time, the LED is green but the battery is at 94%, which I think might be okay.
Maybe the wipe/superwipe/reflash helped? I will keep you all updated and I sincerely appreciate the help and advice.

If that one time results in a battery that won't take a charge, then it hurts. Full discharge is also not good for the long term life of Li ion batteries. And it certainly doesn't help anything to run the battery to empty.
Yea I don't know how many times I've corrected people still quoting NiCd rules for Lithium ion batteries phone or otherwise lol. Anyways if the stock does the same thing it is probably the phone. Especially after a wipe, was it a clean reflash of the rom? Maybe that would work.
Here's my update. Kind of interesting.
So, by evening, my phone got down to 4% left of the battery. I plugged it in, (with my factory charger), and ZDBox said it would be 2 hours, 44 minutes until fully charged. Three hours later, it was at 45% full. I rebooted the phone and when it came up, it said it was at 86% full. Then I left it plugged in over night.
This morning, it was still at 86% and I rebooted it again, and then when it came back up it was 93% and within a couple of minutes, the LED turned green.
So, with this new batter, it *seems* slightly better, but I don't understand what's going on. This is weird, if you ask me.
The other bit of info is that at 7AM it was 93% and right now, (9AM, two hours later), my phone is at 72% with the majority of it being consumed by "Cell Standby."
I guess, since this is a new battery, there still might be some calibration/conditioning going on. I am still unsure if this points to a hardware issue with the phone.
Thanks again, for the help guys! I really wonder if I am the only person who is experiencing something like this.
Update: 19.09
Things have been a little better, but still not perfect.
I flashed CM7 Nightly, pershoot kernel, and 4.30 radio.
I have only been plugging in the charger when the phone drops below 20%. The phone only charges to 45% - 51%, then I reboot, and when it comes back up, the battery will read anywhere from 88% - 93%.
Once unplugged the batter rapidly drops down to the low 80's - mid 70 percentile and it stays in that range for a much longer time. Then once the battery drops below 40% is drains rapidly.
So, for example it says right now, "7h 54m 58s on Battery" and I'm at 20%. The breakdown is as follows:
Android system: 57%
Cell Standby: 12%
Wi-Fi: 12%
Phone Idle: 11%
Voice Calls: 9%
I'm really frustrated with having to reboot the phone to get seemingly get a full charge.
I think I am going to flash the latest nightly and then reflash the pershoot kernel and see where we are at that point. I still haven't decided if I need to call T-mobile since it could be a hardware issue.
It really sounds like a hardware issue to me. especially after several so many flashes and batteries...

Indeed. I called T-Mobile this morning and they are sending me a new phone. The guy asked me to inspect the battery, contacts, etc. He did ask me if I had put any "modified" software on it.
He also said, if they found modified software on it when they received it back at the shop, I would be charged a $108 restocking fee.
Quick, where's that downgrade guide!
Thanks for your help, everyone!
Update!
After I talked to T-Mobile, I downgraded my phone to the OTA Gingerbread and unrooted it, and turned S-ON. I admit, I was impressed with the OTA update since I had been running cooked roms since I got the think back in November 2010.
My new phone came today. Immediately, the battery behavior is completely different. I took out my battery from my old phone that said it was at 51% and put in the new phone and it said it was 80%. That's a good sign!
While we were at dinner, I got all the OTA updates, which really meant when I got home I had to downgrade it, but the guides here were really great, and I was back in business in no time.
I went with the latest CM7 nightly, the LEAK radio, and the latest pershoot kernel. I can tell already that battery behavior is much better.
Interestingly enough, on the stock gingerbread ROM, the DISPLAY was the major consumer of battery. Now on the stack I described, "Cell Phone Idle" is the biggest consumer. Maybe the stock T-MOUS radio is the best!?!? Who knows.
I hope this helps others who might be having weird battery problems. Have a great weekend!
I'm having this exact behavior where I can't get past ~73% without rebooting, then it goes to ~93%, which is about as high as I can get it. Guess I'll call T-Mo, I've seen it with different ROMs to I figured it was probably hardware as well.
Hey Thermalx, I hear you! The replacement phone I got from T-Mobile is behaves completely different. I have kept a charge +26 hours. I never thought I'd see the day!
Let us know how it works out.
Thanks!

advice on abnormal battery drain

I will start out by saying I have ALMOST tried every trick or hack or mod software related to attempt and resolve this issue.
I will let the screenshots speak for themselves.
I am starting to think there is something physically wrong with this device which is odd because when I opened it up to take the plastic cover off to expose the boards I found no evidence of any liquid intrusion at all.
Only one of the pictures is from a different charge cycle maybe a day or two after the others.
To be specific I am trying to eliminate deep sleep battery drain as much as possible. my htc one x does not drain anywhere near what this galaxy s3 does even though everything is disabled. I've tried different rom / kernel / settings / screen / leds / sync / etc.
Wondering if someone might notice something I've missed here.
thanks!

It could be app updates. There was an update to Google drive just a couple days ago and that night after I updated it my battery died overnight when it was nearly fully charged. I cleared the app cache and data and the phone is back to normal. I've seen this happen with a few app updates lately.
Hope this helps.
It could be, and quite possibly is something like what jack man said above. But it could also have to do with the battery itself getting old. Many of these devices have been running for over 2 years now, and the batteries do go bad.
If you really think its a hardware issue though, the only way to know for sure is to flash stock firmware via Odin, factory reset with stock recovery (wipes ALL your apos and data), then test it out over a couple of full cycles without restoring any old data. If you are running anything custom, or restoring backup data, you have way to many "unknowns" to make a call on whether or not it has anything to do with hardware.
BBS is great, but unless you use and post its logs (including kernel wakelocks), it won't really tell you much more than you already know and the logs are much more helpful to us than screenshots.
Mine started doing that a couple weeks ago, for like two days the battery drained like crazy even though it was deep sleeping fine with no wake locks, 16% loss per hour ... I replaced the usb cable I was using to charge it, as it was going bad to where you couldn't touch the phone without hearing the connect/disconnect sounds cycling rapidly, bought a ventev 2.1 amp charger to replace the 0.8 I was using, and did a battery recalibration, now all is well, draining less than 1% per hour with screen off, averaging 1.5% during the day with occasional usage. And that's with the stock battery that's been in it for 18mos.

brand new OEM battery from amazon.com - I got the phone stock w/ original battery and noticed the drain issue, first thing I did was order a new battery and flashed CM11 to see what would happen.
drain exists all across the board with this one.
I've also tried different chargers and cables, and even the charging dock on my radio.
what re-calibration method did you use?
I let it run dead till it shut itself off, charged to full while powered off, booted back up and wiped the batterystats.bin, then let it drain all the way again before going back to normal charging cycles.

What is the date on the new oem battery? There are still places with "new" batteries that were actually manufactured 2 years ago. Leaving them shelved for that long they can still go bad. Probably not the caes but figured id mention it anyway.
I will check on that date. I bought an oem samsung charger from bestbuy last night to do a full charge with the phone off. I let it drain down to about 40% from idling and light usage. I've read of people getting better life after using an official charger after several charge cycles.
Ive heard that too. Definitely worth a try, though Ive always thought what matters is the output be the same, but I could be wrong. Never really looked into it.
While trying the new charger for a few cycles you should also set BBS to start monitoring and logging your wakelocks. (Dont forget to tell it to include kernel wakelocks)
This way if you are still having problems youll already have the logs we would end up asking for anyway.
will it save the logs if the phone auto shuts off due to low battery?
I think it should
looks like the logs reset because I have to plug in the phone to get it to boot back up.
either way, the new samsung brand charger doesn't make a bit of difference in terms of battery life, but it does charge the phone a hell of a lot faster haha!
I even did an advance wipe in twrp so I was left with just recovery and download mode so I sideloaded yesterday's CM11 nightly and left it bare with no gapps. also flashed BMS kernel through sideload.
turned everything off (location/wifi) put in airplane mode, and still loosing about 8% an hour with no suspicious wakelocks or "alarms".
what is the difference between the two?

I'm having the same issue.. Pain in the ass.
I've factory reset, clear cache then flashed with Odin the stock 4.4.2 firmwares for Bell, Rogers and Telus, all have the same drain. When I add my google account I get Google play service keep awake issues.
Phone doesn't last 1/2 a day. From 100% it drops about 10%/hour when in airplane mode and 15%/hour is play service is enabled.
I'm blown away by this. The battery isn't the issue, I pulled it and swapped with a known good s3, the drain did not occur on the other s3.
I'd love to get this resolved.. If I can't, on to ebay it goes.
Yeah I'm with you on the eBay thing. At&t maxes trade in at 55 bucks in mint condition. I have to recoup the cost of this new battery from amazon !

Try ininstalling updates for google play services. I know ive seen it reported before, i just cant recall if that was the fix. I knoe it was simple though.

Can you get logs of this situation? In your previous case you had an apparent problem with Google Play Services where it would wake your phone up to 32 times per hour. That said, if you still get battery drain like that, after full wipe w/o anything waking your phone up or any wakelock then something is definitely wrong with either your battery or your device.

No BBS = no troubleshooting. From your screenshots one can see you have something keeping your phone awake, but we can't guess what it is.

BetterBatteryStats. It's pretty much the number 1 tool to diagnose battery issues.
