My battery life

Hi, I am noticing that my battery life is very short. I have to charge my phone atleast twice a day. Last night I watched a program on my phone which was forty minutes long. After that my battery was already 60 percent about. However.now, in the morning, I woke up and checked one thing on the internet by 3g and now my battery is already 40 percent. Why is this .... I know that battery life on here is not good but mine seems worse.
Is anyone getting the same?
Thanks in advance.

Tell us your settings:
- Do you allow background data?
- Do you always synchronize?
- Do you enable data connection?
- Do you connected to the Wi-Fi all the time?

I swear my battery life is far far better since i put that Generic rom on, maybe the minor updates htc have released help battery life ?

Maybe the update will fix the battery life issue? We'll see when it rolls out on t-mobile handsets.
Other people have reported excellent battery life (mine only arrived today) and it seems to improve over time. How long have you had it?

I had mine 1 week today was originally on the T-Mobile rom and have had terrible battery life up to even yesterday, updated to the Generic Rom yesterday and it honestly seems to last longer now.

I was waiting for someone to report this before I did .. I too was originally on the T-mobile ROM and updated to the Generic ROM. I didn't notice any increase in battery life. In fact I didn't notice any changes apart from the minor T-mobile branding having gone.
Yesterday I did the OTA update and again didn't notice any changes. I did this morning though, in 10 hours the battery only dropped 4%. Of course the phone hadn't been used in that time and I have wi-fi and bluetooth switched off but I am sure this is a lot better than I was getting.
Maybe the OTA update has improved battery life. Let's hope so.

Hello again,
Is the generic Rom the Rom without the T-Mobile stuff?
How would you get that? And would that remove your warrenty / insurance?
How have some T-mobile people get the OTA update whereas some have not?
Have you realy found a difference with it?
THank you

Yes to without T-Mobile stuff.
You can download it in the Android Dev Desire section on here. There are extra steps to take.
It WILL void your warranty.
Anyone that got their phone direct from T-Mob will NOT have it unless they did it manually. And by that i mean manually flash generic rom then update.
I noticed my battery is better but it's only one day. And i never really had a problem with it. I charge once a day anyways.

Thank you for the help.
However I am unsure if I should get the generic ROM.
What are the other advantages?
Because there is not a lot of T-Mobile stuff on there.
If I got mobile insurance with T-Mobile and flashed the ROM would I be able to claim if my phone got damaged or lost?

Advantages. The phone is as it would come straight from the manufacturer. You will always receive updates for the device before Vodafone, O2,T-Mob etc would have them ready.
If the phone was lost then yes. If damaged...probably not but if it develops a fault you can always drop it in a drink and claim on he insurance...bit dodgy like!

My battery life story
So, I downloaded the brut Google nav mod the other day and haven't had a chance to use it until today. Took a journey which took about one hour, and made sure that my battery was fully charged before I went. I still hooked up the phone to the car charger though, to save power. One thing I noticed about charging the desire, however, is that if it identifies the battery as being already full when you connect a charger, the indicator light stays green, so doesn't top up even when you have been using it for a while. I noticed this about 20 minutes into my journey by which time the battery must have gone down quite a bit. Removing then replacing the charger sorted the problem and the Orange light indicated that it was charging again. By the time I got to my destination the battery was at about 50%.
On the return journey, I hooked up the phone again, turned on Google nav and set off. About 30 minutes into the journey I stopped off at a petrol station to grab some snacks, checked the battery and read 17%! Even though it was supposed to be charging the whole time!! I then got a message saying that the power from the car wasn't enough to charge the phone and I should attach AC power ASAP, which I obviously couldn't as I was in the car. I ignored it, got home safely enough, disconnected the charger and then watched the phone die .
Ok, so I was using gps and 3G which clearly uses up power and I guess Google nav is fairly processor hungry, but I would assume that having it connected to the car charger would be enough. Coming from a tocco ultra, I'm used to rubbish batteries, but at least that would charge up in a car.
Don't get me wrong, I still love the phone, but I just need to know if this is gonna be a regular issue, or something that can be sorted out with a Rom update.
Just for info, I've had my desire for nearly a week now on TMO using the old Rom. And, the car was Passat estate which is in very good nick, so I doubt that was the problem.

I would look if the charger really charges the phone or if it drains it also when not using GPS/Nav etc.
Reason I'm saying this is that I once bought a charger that actually drained the battery instead of charging it, while it worked fine on my older Nokia phone. I'm assuming the phone deactivates some power saving features because it thinks it's hooked up to a charger, but at the same time the charger is too weak to actually charge it.

I have not used branded rom before on this phone but the htc rom battery life is fine. Mine has been going for three days with usage fine

nice, 3 days. how many times u charged the phone since u got it?

Try out Locale app... will definitely help saving battery power: twofortyfouram.com

intresting my battery last a day

I just started charging 2nd time my battery and it lasted hmm since about 2pm till 15% at about 00.00 which is pretty much 10hours of heavy use. i did leave it on sleep for about 2 hours though and i left it at 25% and after that it had 25-24 % lol so if you turn all the updates off it will last quite a lot i guess

I rang up T-Mobile today (tech support) to ask about the lack of update considering the rom was behind the non carrier phones at the start and then an update too. They said they do work on them when they see a notable difference worth updating.
Anyway, I also said I was incredibly dissatisfied with the battery and how long it lasted and wondered if it could be to do with the ROM being well behind the stock HTC one. The tech support guy was excellent and very helpful. He said that with the type of battery in the Desire, you need to make sure you have it on a MAINS charger from quite low for a good couple of 14 hour sessions with the phone off. This builds up the charge for the battery and you should see a marked improvement. He said that most people don't bother to do that and as a result get poor performance.
He did say him and 4 members of his team have the same phone and while some of his team had battery issues he didn't. The main reason being that he had spent a few days not taking it to work and running it down in the evening then giving it three 14 hour chargers. He said that made a huge difference.
He also said if I was dissatified to a point of big frustration they would replace the phone or refund. Can't ask fairer than that

[Q] G2 ate 45% of my battery in 1 hour (UPDATE)

UPDATE BELOW
So here I am sitting here on the verge of a fit that would not be good to have at work.
I went to my friends last night (a pro at android phones) and was hanging out with him. I brought up the fact that I have been having REAL BAD battery life. So he takes my phone and looks at it running some tests. He proceeds to look up at me and states " you better call t mobile and get them to send you another phone." *swears like a raving loony* This is after running the battery dead and leaving it on the charger for 8 hours to condition the battery. When he said that to me by the way he explained that my phone is searching for a signal 55% of the time and that is what may be eating up my power. NOW, I know for a FACT that I have a 100% signal all day long... I live next to a t moe cell tower and work next to one also.... and during my commute I have 100% signal.
I guess what I am asking here is has anyone else seen this happening on their phone? I also noticed after my buddy downloaded a system monitor that the CPU is running at 100% all the time. Common sense with computers tells me BAD BAD BAD.
Why am I so upset over this you ask? Well, the service of t moe's signal and quality of the network of where I live is GREAT! However I have had BAD luck with all the phones I have since I have been with t-moe. The Rzr: sent that back about 8 times ( went and got a windows phone with my own money after that), the BB 8900: 5 times, and now all this BS with the G2 after just having it a month is getting to be a friggen P.I.M.A.
I know they are going to want to send me just the guts of the phone and not a new one.... I WANT A BRAND NEW PHONE! I am sick of referbys. It's a waste of my time and money to be driving to the [email protected] mail box to drop off the return.
HELP!!!!!!
Your loyal 911 Dispatcher.
P.S. to give you a good idea of how bad the battery is being eaten up I was at 100% this morning at 6 am. Now I am at 64% and dropping fast. So I always have to have the phone plugged in.
Update people:
Yesterday when I got home I called T moe and talked to a Retention CS. I went right to the top. The lady I spoke with was either blowing sunshine up my arse or she was telling the truth so take it as you read it here I guess.
So first thing I did was explain to her (nicely btw) of all the issues I have had in the past with all my other phones I have owned with them. Of course she did sound concerned. I also went on to tell her that if we do go to the point of sending me a replacement that I wanted a new boxed phone and none of that crap in a UPS box with stuffing.
After some conversation and questioning of my phones history she advised me that:
1. The issues that I (and others) are having are known issues and they are well aware of it and are working closely (In bed with them?) with HTC about it and should be seeing an OTA soon with a fix. ( I will believe it when I see my phone).
2. I figured since I had her on the phone and laughing that I would press the issues of the teathering rumor... Now again take this with a grain of salt if you wish but the details she told me leads me to believe that she is very up to date on what is going on. She stated that in fact they are working on developing something about charging for teathering... I didn't press the outside apps for teathering though. She stated that it would not be a contract thing and that you could activate and deactivate it as needed on your account so that you were not always paying each month for it if your not using it.
3. Battery draining issues. Solution..... Sent me a new battery via next buisness day shipping. Said I had a bad battery.... Also told me not to keep the phone plugged in since that is the fastest way to kill your battery and that I should discharge it and rechage it as needed.
So there ya go people. Again take it how you want but I hope me spending this time typing this out helps. ( my boss is paying me to type to you guys )

Try pulling the battery off your phone for one min and then reinsert it into the phone. Was having drainage issues like you and that helped. If not try a factory reset. Who knows... that could help.

Try going to settings, applications, manage applications, and check and see which apps are tuning in the background. If an app is piling a load of data then that could be what is killing your battery.

Already done and done..... Only the basic componants of the phone are running and a few things I am always using handcent SMS, Beuty widgets.... and batt watcher.

Did you try a factory reset and not install ANY apps. Maybe that beauty widgets is killing your battery or batt watcher. Or you may have a defective battery.

my wife phone the 1st day battery ran out real quick but maybe because she was texting to much but i use my brightness at 100% and i wak up at 9 and lasts me to like 10-11pm and about 40min of uno played

Well my wifes phone is running the same widgets and programs that I am.... I take that back shes running 3 times the ammount I am..... and her bat lasts her all day and then some...

In the beginning my phone had the same problem too..but now its way better I use to recharge my phone twice a day but not nomore..I think just wait it out..that's what I did..and my friend also just bought this phone and she's having the same problem..I think its just when there brand new it does this

I ordered a evo / mytouch battery off amazon supposedly they fit the g2 and you get about 30% longer battery time.

just a quick update thread bump... update in my OP

I noticed this too. One day my batt lasts all day, and well into the next.
Other days (twice now) the battery, on the same setting, with the same usage,
drained obnoxiously fast!
This phone has some serious schizophrenic issues.

Battery Question:
Is the Tmobile G2 Battery 1300 mAh? ir 1400 mAh?
Only asking because I went through three G2 reviews and they all list it as 1300 mAh, however the HTC Desire Z coming here to Canada is listed as 1400 mAh... ?

Wait, how am I supposed to not keep it plugged in? I plug mine in before I go to bed and unplug it when I wake up. Am I supposed to wake up an hour and a half into every night's sleep to unplug my delicate phone? Why the hell don't they just have it stop charging the battery once it hits 100%?

I am 9 days in on my fourth G2 and until this morning i believed I had a keeper. By a pure twist of luck I did not have to get up at 5:30 am so as to arrive at the tennis courts to give lessons. Upon arising at 7:20 am I found that my battery had gone from 100% to 1% and turned itself off. The phone was in standby when I retired to bed and had not been used the entire night.. Obviously the alarm had not gone off and the phone was unusable. Upon plugging it into a charger it still would not boot up. After waiting 15 minutes and letting it charge I tried again and it did boot up and showed 60% of battery. I have never ever had a battery charge to 60% in just 15 minutes. Upon checking battery usage I found the following: Android system 27% Shop Savvy 23% voice calls 35% Display 11% phone idle 4%. I had not made a phone call and had not launched any apps. I certainly had not used Shop Savvy and the display had been off. I have noticed recently that upon waking the phone up I would be running various apps which I had not launched. I use my cell as my alarm so I cannot keep it if it is not dependable or is acting erratically. Has anyone else had this scenario happen? I have been reluctant to give up on this phone but after 4 units all with issues I guess its decision time. NOTE it just dropped 19 % in less than 3 minutes while in standby, with no apps being launched by me and the phone just sitting there in sleep mode. Just tried to access the market and no go. I am experiencing only G or E where I normally have good 3G or H. Perhaps this is T Mobile and not the phone but this happens way too much and does not occur with my Vibrant or Nexus One.

[Q] Terrible Battery Life - Hardware Fault?

I've had my new desire z about 2 weeks now, and am utterly dissapointed by a frankly dreadful battery life.
It's my second DZ, given the original was nicked, but (kicks self) wasn't insured, so was purchased from a supplier that shipped my phone from Hong Kong (I live in UK, and the new phone is an identical model, except for a slight difference in key layout - A2727 I think is model number)
The original phone would give me over two days life with very low use, which i considered to be fair for a decent smart phone.
The new phone barely gives me 10 hours with no use. I've done a couple of tests - unplugged it at 2am, but 8am it's at 30% or lower. This was done with all data connections turned off.
If i leave the new phone to go dead then that's it - it won't charge. The only way i've found to get juice back into the battery is to hold it in my old touch-pro 2 until it's charged enough to charge from the desire.
Last night was the clincher. I've gone out with some friends to the pub. I had a conversation over it, and checked my battery life - 42%. As a last dith effort i factory reset the phone at that point to rule out a mischevious app, and checked - 39%
Within 2 hours, and with no use at all that was down at 8%. In order to avoid the charge issue i cut my losses and turned it off at that point. Once home (oh, about 4 hours later maybe) I was unable to turn it back on. I then left it plugged in overnight, and was still unable to turn it on this morning until i'd done my cross-phone charging trick.
I'm now entirely convinced there's some form of hardware issue at fault here, so i'm wondering if anyone else has had the same problem with this phone before? I see lots of thread regarding poor battery life, but most seem to be solved by turning data off or some rouge app, neither of which are an issue in this case. Also, any hints for making my life easier when I phone HTC tomorrow? I've read elsewhere their support might not be all it should be.
Thanks in advance for any help! I've ready to pull my hair out as what is a fantastic phone otherwise has been completely ruined by this battery issue.

I think you should get a new battery to rule out that the battery itself isn't a problem. I had similar issues with my G1 a while back and it solved a lot of wierd, seemingly unrelated problems. Batteries are pretty cheap online, $15 or so and some are free shipping.
The way that I figured out my battery was toast was by comparing it to other batteries. it had a bulge in the center where it should have been flat. Fingers crossed it isn't hardware.

had already tried a diff battery (did you know you can chew a corner off a touch pro 2 battery and make it fit??) Which i know worked fine in the old nicked dz and imo as i was getting same issue ruled out battery problem.
anyway... phone has now been returned and i'm waiting 2-3 weeks to get it repaired under warranty (though am hoping for complete replacement obviously)

Chewing on batteries has got to get you extra xda brownie points. I'll remember that

I'd like to think there was some techincal or engineering skill in there somewhere.
but it was mostly "Well, apart form this nugget of plastic they're the same shape..."

I'm having the exact same problem... When you take you shutdown to recharge a dead battery, does it sometimes try to turn back on? I left my apartment like 30m ago with 100% battery, and I'm at 84% and declining. There's nothing running. And I've replaced the battery, same issue.
I think I might just RMA this one.. seems like an engineering issues.
Edit: I'm the 40 seconds it took me to type this, battery dropped to 82%.

Wanted to bump this post. I've since wiped / reloaded and wiped battery stats. It's still jacked. I think it's an internal electrical thing. Reason is: I'll power down to take the battery out. When I put the other one in, it'll turn back on. Or if I power down to charge, it'll turn back on - plugged in or not. I don't want to deal with the RMA process again, but I think it's my only choice. I've taken two phone calls this AM @ 100%, and it's at 96% now. Drives me insane. Ugh... I'll call TMO. Anyone know if the replacements are still rootable?

So... I had my phone replaced, and it's still doing the horrid battery thing. Flashed CM 7.1 RC3 or w/e the latest is, cycled one battery - and it drops like a stone. I have two chargers (one at work, one at home) and they both charge the phone up to 100%. But it's still losing battery life quicker than I'd like. I used to be able to get a good 18 hours out of this phone. Even with a new battery and a new phone, it's acting up. I'll try to flash an older ROM and see if it's the same thing. I updated to #130 nightly from 7/10. We'll see how it lasts today. But I do remember I had horrible luck with CM's ROM's on my G1. Battery would just drain for no reason. The main process taking up the most battery life is "Cell standby" so I changed to the latest radio - and it still drops. OP - have you figured out your problem? I've removed a ton of apps, and it's still messing up. I listen to music for... 45m in the AM, and I get down to 54%. I've formatted my SD Card as well.. it's driving me insane.

I just flashed CM 7.1 a few days ago and while the ROM is great, it does seem to be a litter harder on my battery than 6.1 was. With light/moderate usage yesterday, I got about 16 hours and that was running the battery almost completely dead. With heavy usage, I get about 10 hours and need a bump charge in the afternoon.
You might want to look into getting a Mugen 1800mah battery. You can get them on Ebay from 35-40 dollars. The seller 'nakedcellphone' is based out of Southern California and another user has confirmed ordering from them and getting a legitimate battery (lots of fakes on Ebay). Either that, or carry a charger with you...
Have you tried using Watchdog to see if there are any 'rogue' apps that are causing the drain by running in the background? What about going to spare parts > battery history > Partial Wake usage? There it will show apps that are draining your battery when you're not 'actively' using your phone. For me, the Android System is the highest drain in that menu. Good luck! Hope some of this helps!

I just checked spare parts, and there's nothing too odd in there. Just my music app. And I've changed that too - thought Winamp was killing me. I'll check Watchdog. This is a brand new OEM battery along with an RMA'd G2. It has to be the OS / Radio or something. I've stripped like every non-essential app too.

[Q] [Poll / Question]Has your battery died since ICS update circa FI03/FI27?

Hello,
so I got the bloated battery issue myself, and had to order another battery. I have seen many threads pop up in the last month concerning this issue, on here, androidcentral, and even the sprint forums!
There doesn't seem to be a unified thread, so I would like to try to get one going. Sprint/Samsung probably doesn't know how widespread this issue is becoming. I think its a more serious problem than we think, and isn't relagated to a few random people. Myself and my friend, who both got our phones around the same time, who both run the same build of ICS started exhibiting the following issues:
1. Insane and unpredictable battery life drops. I'm talking 88% while browsing the web, and then instant reboot and phone is down to 10%.
2. Screen flickers as if auto brightness can't make up its mind, instant reboot.
3. LOS, then reboot.
4. Any intensive apps: camera, gps, sometimes even just streaming music, causes the phone to lock up, pressing home does nothing, may even require reboot.
5. Removing battery, and then letting phone sit for 1-2 minutes, then putting it back in an powering up brings battery level back up to stable temporarily.
6. Battery Bloat, and inevitable: permadeath. Can't hold a charge.
This seems to me to be a consistent occurence along with recent builds of ICS.
I would like to get to the bottom of this. I don't plan on keeping this phone much longer (I ordered a Nexus 4, still in order limbo tho), but it could be of help to the community if we know the how's and why's.
Questions:
- Are you experience these symptoms?
- If so, when did they start, give a specific build number?
- Have you experienced battery bloat? (battery seems to be slightly expanding outward, not completely flat)
- Do you keep your phone on the charger overnight? (This may or may not be related, but maybe a recent ICS change disables something that stops the battery from overcharging)

Interesting! My wife had this exact issue on her E4GT unrooted FI27. Eventually, the phone would no longer boot. She took it back to Sprint yesterday. The battery was bad, they tried another battery and the phone still wouldn't boot. She's receiving a new phone today.
She told me when she was at the Sprint store, there was a guy there with an Evo with exactly the same problem. I told her it was just an amazing coincidence and not an Android issue... obviously I was wrong!
I am on FI27 stock rooted with a newer battery than my wife's, the only thing I have noticed is that my charge sometimes drops CONSIDERABLY after I reboot the phone... now this has me worried! Her battery was bloated. We both charge overnight.
Obviously, this is an issue that you can't ignore, because it can fry your phone (as it did my wife's).

Yes!! The insane battery dropped started happening like a month ago. That's all that was happening though. Just random battery drops. I thought it was the ROM at the time. The phone would freeze up, reboot and the battery would be 30%+ lower.
About a week ago I started experiencing the craziness. Phone rebooting, flickering screen, pretty much everything you've stated. And yes I've been using the latest modems. My battery can also spin like a top. For a very long time I might add. Some other dude with a regular Qwerty phone has a battery that can spin, but it only spins for like 3 seconds. His phone is pretty old.
My phone is about a year old and the battery spins for ever. I guess this is a good test to see how bloated your battery is, since I can't really look at it and tell.
I do charge over night since my phone would die over night. I don't think my phone will fry right now since my phone is on the charger and the battery temperature is at 66 Fahrenheit (18 Celsius). Ordered a new battery hoping for the best. And I will be using ROMs that are based on the FF18 with the new battery.

first power button broke, now battery is taking a **** upon itself, exact same issues

Check this out... as I said, after my wife had been having this issue for a couple weeks on her stock E4GT, on Thursday her phone would never boot past the boot screen. She took it into Sprint on Friday and they determined the battery was bad. They tried a new battery, still wouldn't get past the boot screen. They ordered her a new phone 'overnight' which is supposed to arrive Monday. She is going into withdrawal, so for the hell of it I plugged her phone in, booted to stock recovery and did a factory reset... reboot and the phone (apart from the bad battery) works perfectly. My wife asks why they wouldn't have done that at the Sprint store? What a bunch of idiots!

Hello,
so I got the bloated battery issue myself, and had to order another battery. I have seen many threads pop up in the last month concerning this issue, on here, androidcentral, and even the sprint forums!

I have the above listed problems with my SOny Xperia Arc S after I updated it to ICS.. It is kinda frustrating..coz it turns on and off by itself, or sometimes it just froze that will makes me manually take out the battery..But when I haven't updated it to ICS there are no problems like this...

Do look in what forum you are replying to before replying. This is the E4GT forum. NOT Sony!

This is a specific problem related to E4GT. I think its the characteristics of this problem that make it unique, the instantly dead battery, the battery bloating, and something to do with recent ICS updates. I am hypothesizing that it has to do with battery overcharging that somehow got introduced to recent builds of ICS that is causing this.
I just got my new battery in yesterday, and sure enough, it fixed all of these problems. It's an Anker battery, and, although I am no expert on batteries, its a really nice third party battery, and feels weightier than the stock Samsung battery. Now I'm worried that ICS will destroy this battery as well, so I am being very conservative when it comes to charging.

I was having the same issue with my last E4GT running FI27 STOCK ROOTED.
1) LOS to reboot then low battery from full
2) using apps like spotify, maps and voice search on 3g would also cause it to reboot to low battery
3) screen flickers (like cm10 flicker) and then reboots

I don't think the issue is related to ics but rather the age of the phone, but i could be wrong.
Has anyone had their battery die after upgrading to ICS when their phone was less than 8 months old?

Pesonally, I agree... my belief is that this is a battery age issue. Now, I won't say that the battery should age so quickly or that it should start bloating, but no one has had this issue with a newish battery have they (say, newer than 6 months)?

I dunno man. I have had an Epic 4G, an HTC Evo, and evne HTC Hero that I kept for quite a while and their batteries never bloated and exhibited these kind of software based issues. Sure batteries degrade over time, but it's almost like the software was glitching out when it was killing my battery and causing strange reboots and lock ups, not to mention instant drain.

new battery bloating within 2 weeks

Hi there, first post here, I was just browsing the web for help with this issue and found this thread. My galaxy s2 eg4 also had the bloated battery after ics update, it was shutting off randomly, flickering, etc. I replaced the battery first part of december 2012, and within 2 weeks it had started doing the same thing again, but not as often. Sure enough, brand new, previously flat battery was slightly bloated. It has gradually gotten worse, so I just purchased 2 new anker batteries to see if they fare better. When I changed the battery and took out my one month old battery, it was quite bloated and spun for quite a while.
Hoping it does better with the anker batteries, but only time will tell.

Batteries bloating has nothing to do with ICS or the software. Its a heat issue and weak cell walls inside the OEM batteries. The cell walls barely meet requirements to make the 1800mah cells fit in a 1500mah size housing and they don't hold up well to high temps. as the battery reaches 120°F+ the solid state chemicals used in the cells begin to expand, a normal battery's cell walls can withstand the slight increase in pressure but the thinner walls in these batteries begin to crack and/or separate from the housing and then the chemicals can mix. Once the chemicals begin to mix the reaction causes the air inside the battery to expand and swells the housing out as it has nowhere to escape.

I have the same problem l. Even with a 3800mah battery. It will start.acting up and if it gets better it will all of sidden go up to 70% or more, and i know it takes a couple of hours to get it to 70% from being dead at 15% or less.

I have been using the anker battery for over two weeks and no issues, longer battery life, etc. So far, so good. :fingers-crossed:

Most definitely a battery issue, especially when your phone is a year old or close to it, I don't know what was up with ics but that sure put hurting on the Epic Touch.
I have two Epic's and they are both 14 months old and in Dec they both got new batteries, an Anker and a original Samsung and they are both running like new again. Ones on GB and the other is on JB roms.
They both experienced the bloted battery syndrome and they also experienced ics, for a short period before going back to GB and now JB. Ics was a catalyst for the batteries to fail the way they did, not to mention that charging and discharging a battery for a year or so is going to also take a battery to its limits, especially when you plug it in overnight. At present we have no issues with our Epic's and we are just going to wait it out for the GS4 to get here before we upgrade.
EViL is on the right track even thought he likes to break stuff.

[Q] Weird battery issue

Hey guys, just got the phone on Saturday. It's been awesome until today. I noticed it has been draining super fast. I put it on the charger and it would not charge past 89%, and at 89% it said there was 1m left until full. I turned off the phone and let it charge to 100%, but when I turned it on it almost immediately dropped to 90%.
What could be the issue? Do you think a simple factory reset could fix it, or should I take the phone back to Best Buy for a new one?
Edit: using the corded charger that came with the phone

This just started happening to me as well.
My phone will say fully charged, and when I unplug it will immediately drop to ~91-93%. Not sure if it's a faulty battery or what not, as I too have been using the wireless charger and block given to me with the phone.
I'm going to Best Buy during my lunch today to see if they have any idea and will update if there's any useful news.

that is weird. I haven't had the issue on mine, though I only charge with a USB cable (I don't have a wireless pad). From my rooting days, there is a battery config file that remembers things like battery charging history, so a factory reset might be useful, though it's a painful process to get a phone back up and customized fully after a reset.
Hopefully best buy has a better answer...though it might be as simple as replacing the phone, to which a factory reset might have been easier...

Anchor - how is the battery life on your phone?
I think my battery might be a defective one as I can barely get through half of a day with 1 1/2 hours of SOT - and that includes taking several steps to try to maximize battery life.

Just a quick update:
Stopped by Best Buy today and talked to a surprisingly knowledgable Samsung person. He said I'm the second person with an issue like this and believes it's a faulty battery, so they're going to give me a new phone.
To my knowledge this is the only explanation as my battery was lasting half a day.

Same here... I just got this phone yesterday and the battery drains very quick. I will return it and get the htc M9.

Final Update: Battery has been much much better on the new phone. Previously I'd be around 50% by lunchtime and today I'm at 85% with nearly the exact same use.

what was your usge in your previous phone?
