Hi all, i have SNS just few day old, the wierd problem with it is that no matter what ROM i am on, the battery stays good with consistent discharge pattern till around 30%-35% after that it just nose-dives and goes to zero within 45 min... i have done everything i know like tested different roms, with/without any apps, JB, CM9, ICS, GB, everything behaves same. I also tried to calibrate the battery by 3-4 charge discharge cycles, removed battery stats, but still it persists.
While charging back from 0% it charges rapidly till 30%, much faster than normal, also sometimes if its at 20% and i remove the charger, after 5 min it would show 22%!! i dunno what to do now... Anyone has any idea?
I'm no expert but that does sound like your battery is crap... how long does it last on a full charge? Does it get especially hot or something? I mean if it were a software issue, the power would go somewhere and that's either display or CPU, with a battery drain like that your phone should be glowing and steaming after 45 min.
I hope I helped a bit at least ... Good luck!
Well no, i dont think heat is an issue... even when it dips from 35% to 5% it does not heat up... when charged, during the night too i get 5-6% battery drain which i assume is ok... it lasts around 15-16 hrs till 35% so thats kinda ok i guess but after that it just goes haywire... no clue... i tried to calibrate many times but it just does not get better...

In that case swapping ROMs/kernels won't help. I suggest you get a new battery, but that's just my opinion. A drop like that in such a short time without the device getting hot is definitely not normal
Any one know where can i find a genuine battery who would ship internationally?
But why wont the battery discharge gradually? lets say even if its bad say 1200 1300 mah it should discharge faster than the normal one but atleast at a gradual rate and not suddenly like it does on mine... even after calibration??!!

Hi guys
I have a galaxy s2 and im having problems with the battery. In the battery usage section the most that takes up the energy from the battery is the display. Even lowering the brightness settings the display is still sky high. Now having flashed it few times the warranty has now gone. Tried different roms and still the display on my galaxy is like 45 to 55 percent. Some say its normal some say its not. Once i fully charge the phone within minutes the battery starts getting drained. Seriously what is wrong with it and what can i do to resolve it. Im past my month that i could send the phone back and samsung obviously will find out its been tampered with ie me flashing it
Is there anything i can do to solve the problem with firmware or am i stuck with a faulty phone and just make the most of it till something else comes along?
Any help or ideas will be appreciated

The battery might be dying. How old is the battery? Li-ion batteries will work for 3 years or so only regardless of whether you used it or not.
The display might be taking up so much battery because that's how you use the phone. ie you don't use much of other battery heavy stuff. Make sure you have a low timeout for battery as well.

The display battery usage will be relative to how much screen on time you have. If you are having problems with how long your battery lasts, download BetterBatteryStats (from my sig) and run it for 24 hours or so then check the wake locks to see if any rogue apps are draining your battery.
If you want to return the phone. You can always flash the stock rom and if you buy a USB jig from ebay, you can reset the counter, so Sammy shouldn't know that you have flashed any roms.
For further tips about your battery, why not look at some of the custom rom threads, like Villainrom. They have very good battery stats and there are plenty of tips in the thread.
Hope this helps
well i have it charging at the moment and i am using cognition rom and the phone is like sleeping as we saying. i quickly went into battery usage and display is like 85 %.
Shall i charge it to the max calibrate it then wipe battery stats and let it drain out till its empty fully charge it and then use it till the end of the week and then post a picture of how it went for you guys to see and you give me your ideas on it?
thanks again i really appreciate your opinions
I have never bothered calibrating my Battstats, but it makes some people feel better.
As I said above, the percentage used by display is relative.
If your phone has been on for 24 hours since charge and your display is 85%, then you have a major problem, as your screen on time must be massive.
However if it is 10 minutes since charge and the display is 85% then that probably equates to a few minutes screen on time.
Once you are charged. Run the phone for as long as possible then post screenshots of the Battery Usage (both pages)

Agreed with killall. Battery stats are relative. Say you have used your for ten minutes after charging and the screen was on for 5 minutes or more, an 85% for display is nothing big.
Like he said, see the overall performance of the battery and its life. Display percentage doesn't make that much of a difference if you use your display a lot. I mean if you don't do much CPU intensive gaming or stay connected to wifi and stuff.
So this has happened twice now. I'm running on ARHD 4.1.0 w/ Bricked 1.0.
My battery will be running normally, normal drainage, etc., and then it'll just drop from 90 to 70% in less than an hour, and normally drain for another hour or so, and then at around 60% just die. I can't attach a screenshot since normal screenshot apps aren't working and the stock function keeps producing invalid images, otherwise I would, but it literally just looks like it got to 60% and instantly dropped to 0%, there's just a vertical line of missing percentage. I took my phone out of my pocket, expecting it to be around 40 or 50%, and it wouldn't turn on. When I hooked it up to the charger, it took a good 5 or more minutes to even respond to the power button. Do I have a bad battery or just incredibly out of whack battery stats? I have never had this problem with an android phone before, and I thought for sure one full charge overnight would fix it, but I guess not because it happened twice. Any suggestions?
Edit: I use an app called battery snap to monitor the battery level and temperature with a widget, I checked a snapshot history while it was charging and for a few seconds it was at 0.002 volts. But then it jumped back up to 3.897 or something around there. That doesn't sound very good to me.

I don't know much about this, but I don't think battery stats have anything to do while the phone is dead. Even if it does, the phone would at least respond after a minute or two, not 5..
My suggestion is that you can order an Anker battery which is kinda cheap ($15 I think) and try.
You won't loose anything
Edit: Try wiping battery stats, do a full charge, fully discharge and fully recharge again and see if it helps (In your case I don't think this will help, but huh, let's hope ;D)

Thanks, I'll try it. I flashed the new cm7, since I just got tired of sense woes. I read battery life on this was amazing, and I'm hoping it was just a bug with the kernel/rom I was using. Battery stats would've been wiped when I wiped for flashing this ROM, so I'll do a full battery cycle and cross my fingers. My only thought is that maybe, if the battery stats were screwed up enough, it thought it was at 50 or 60% but really it was more like 10%. I remember having issues after I flashed the custom kernel, where before I flashed I was at 70%, and when I rebooted I was at ~10%, and I was like what the hell? So it ended up dying on me, but then I turned it back on and it said 50% or something around there. And then it functioned as normal until it died again, for real that time. Hopefully it was the kernel causing the issue. I'll run a few tests with this and see. If it is the battery, I'll try t-mobile for a warranty replacement of the battery.
The battery measurements seem to be really quirky on this phone. When the phone is idle it seems to drain anything from 50ma to 400ma for no particular reason. You cant really rely on the % too closely
Yeah, I've found the percentages to be pretty inaccurate. Hardly an hour and a half on the battery and it's down to 84%. I did play a game for like 10 minutes and the screen has probably been on for 20 or so, so that's not incredibly unreasonable. I'm just waiting for that dropoff to 0%, if that happens again I'm thinking it's hardware, because I'm running an entirely different ROM and kernel right now.
So it just happened again, went from 42 to 14 after reboot, had to remove battery and reinsert to fix. But other people have reported this issue on cm7. So, I'm thinking maybe that it's an issue with android 2.3.5 or the kernel for it, since it's happened on both arhd 4.1 and cm7, both 2.3.5 roms. I'm going to try and flash faux's cm7 kernel over it and see if it fixes it. May or may not, might be a long shot but worth a shot, I'd rather not switch roms for a third time in the same day.
Hi everyone,
I've had my Sensation for about 14 months now and for the past month I've been having battery issues. Primarily, it's very quick to lose charge and will lose charge even while charging from the wall. First I bought a replacement battery but was still having the same issues. I've started using Better Battery Stats and Battery Monitor Widget but I don't have anything out of the ordinary running. In fact, not a lot is running at all. BMW has allowed me to see how the charging is going though which has been nice. During this period I have used Elegancia, Bruce's CM10, and am currently on ParanoidAndroid. All experienced the same issues.
Last night, for example, I put the phone on the charger at 16 percent. It charged up to 22 and then started the downward slide to death and I ended up waking up 35 minutes late.
Where do I go from here so I don't have to constantly be paranoid about my battery levels?
Sounds like you might need another battery. In better battery starts did you notice any unusual wake locks? This could drain a battery. But since it looses charge even when charging I'd think it was the battery. I personally was experiencing some battery issues myself finally I broke down and got a mugen 3800mah battery from mugen. It was expensive but really worth it for Me.with really heavy and constant use I get 20 hours out of my battery, with normal use I get two days. I'm also running paranoid Android rom. For me the big battery solved my issues. Only one draw back, it does make your phone thicker. New back included with battery. This didn't bother me much because of the excellent battery life I receive. Now I finally don't. Worry about battery. However it's expensive at about 95 dollars. But I was so fed up with poor battery life it was worth it for me. You have to be careful when buying inexpensive batteries because there are a lot of fakes going around. And the mah is not really what it says it is on the packages. You can test the battery and make sure it is what it's advertised to be. If you don't want to go with that large of a battery you can also try anker extended battery. It's a lot less expensive and is a good battery. I personally needed more juice so I went with the big battery. I know you said you replaced the battery but sometimes the bargain batteries go bad quickly. It makes me suspicious of the battery because it's even dropping while charging. This is strange. If you ruled out any apps or wake locks that might be draining the battery I would buy a good reliable battery. The draining while charging is a red flag. I'd say the battery is going bad. I don't at all regret my purchase of the big battery. It for me, solved my issues. I do Hope this helps and I wish you the best. Hopefully you will get your issue resolved soon.

its either an issue with the battery or the battery reporting.
Only thing you can really try is to charge it up to 100%, wipe battery stats in recovery, then let it empty totally and charge it up again, see how its behaving. There is a chance that its the reporting that is off.
otherwise this looks like the battery is on its way out im afraid

Argh. I hope it's not the replacement battery too. I got a replacement HTC battery. The problem I'm having getting anything useful from Better Battery Stats is that rarely am I off the charger. In the settings it says I can log while charging but it may mess up the stats so I've shied away from doing that. I'm not against getting a bigger, better battery but I would hate to do that and have it actually be something else hardware-wise where I would need to get rid of my phone.

I'll give this a try if I can get it back up to 100%. Is the reporting in Recovery always correct? The battery never has issues charging while it's in Recovery mode. If that's the case then I'll charge it to 100% in recovery and then wipe and start fresh.
Thanks
I don't think it's the battery. This phones have errors in battery readings. I feel your pain man. Mine is from T-Mobile (Sensation 4G) and it discharges if I use it even at lowest brightness when it's charging too.
If I reboot, I get the battery boost. I have tried EVERYTHING I read here and nothing worked. I even have 4 batteries. All of them in good condition.
I even tried three times discharging it fully and without turning it on, charge it in the night and when I wake up 7-8 hours later, it's still charging. I tried wiping stats, changing ROMs, changing the usb cable and the charger. Everything... I believe it's a hardware issue. (Thank HTC for that) I'm not buying another HTC when I have to upgrade.

Interesting...so if you were to charge the phone in recoery how long do you think it would take to get to 100%?
I would definitely do what you said, charge in recovery then wipe battery stats and go from there.
If you're interested in having something to compare to, it takes my phone about 3 hours to charge to 100% (by the way I'm using an Anker extended capacity battery), with a peak current usually around 800 - 900 mA. Fully charged I have somewhere around 4100 mV. If you haven't already, I'd suggest adding a Battery Monitor widget with mA, mV, and % available being displayed and it will be pretty easy to get an idea what's going on.

I'm leaning towards hardware issue too. That's why I figured I'd post and see if there was anything else that I can try. It's also why I don't really want to buy an expensive battery since who knows what it'll fit next. I know what you mean about the reboot battery boost. You can almost gamble and bet on percentages when you reboot. I've seen 50% swings before.

In recovery I would guess that it wont take very long to charge to full. I have battery monitor widget installed and while plugged into the wall with my 1.0A charger, it will typically pull 100-200mA but sometimes it'll spike to 700-900mA. No rhyme or reason. When idling and functioning properly, without a charger plugged in it drops 9-100mA. Sometimes though while charging it'll sit at negative 100-200mA.
HA! Just rebooted my phone and it went from 68% to 100%. So I rebooted into recovery, it also said full so I wiped stats.

I normally get 2 to 3 mA drain with the phone sleeping. When charging you may not necessarily get close to the 1 A current delivery of the charger straight away, typically it will ramp up over time and reach peak charge current as it gets closer to 100%. Once at 100% it wants to just "trickle" charge to maintain 100% charge until the charger is disconnected, so any wakelocks etc. that cause a current drain during that "trickle" charging will actually decrease battery charge until the charger ramps up to compensate for the drain. Random spikes in charging current would suggest a hardware problem where the electronics are struggling to properly govern the charging process, as would a large negative current drain with the charger plugged in. Silly question but what's the actual plug connection to your phone like? Nice and solid, pins all OK?
Hi there,
Anyone experience that after overnight charging, the battery will drop to 99% instantly just after unplug from charging brick?
I also notice that after its fully charged, turn off the phone and let it charged for another 30 mins or so, once turn it ON and the 100% will stay for 5-10 mins before the 1st drop.

that instant drop is to protect the battery...
its normal...
and for longer battery life dont charge it upto 100%...
charge it somewhere around 85 and use it upto 20%...
85-20 is the best charging ratio..

What? It's not normal. Charging to 100% is fine. It shouldn't instantly drop down.

Due to it being a lithium polymer battery it is best to only actually charge it to around 85%, as when it hits 100% a part of the battery does actually die.. The same idea goes with running it to 20%, that's as low as you should run it, its not like the old batteries where you have to run it in, that's actually bad for the new batteries that operate most of today's devices.. But with that being said, the amount of the battery that dies with charging it to 100% or letting it run to 5% is so miniscule that you'd only notice a difference after around 600 cycles, so around 2 years.. Even then it would be close to a battery ran to perfection.. The difference between 2 would only be around 10%

just saying...
Hey guys, so last winter I had no issues, snowboarding and taking the phone out, it was cold but battery was good. I noticed the past month or 2, now I noticed when battery drops to about 40% it drops fast! And when it dies if I plug it in for a short time it'll bump up to say 30% fast and discharge slower. I ran the battery discharge app, it drained down fast to about 2% then slowed, stayed at 1% for about 18 mins in the app before the phone finally shut off... , when it gets even a bit. Cold, say i left it in a 5 degrees celcuius location for 15 mins, it'll die. I thought huh? Plug it in for 5 mins and bam 68% percent. Today I was out snowmobiling, about - 2c or about 26f? The first half the ride it was ok, airplane mode on it had 85%, then get back to the vehicle and look at it, it was off, try and turn it on, it showed 0% and shut off. Let warm up and bam back to 80%....
What's going on? I think a battery mis calibration? It's bizarre and I've Googled but havent found a fix. Thanks!
Well, I'm thinking a few things:
1. Batteries hate the cold, and can be very sensitive to temp changes/certain temps where they really drop off efficiency. Age and cold can certainly add to their stressed unreliability.
2. If your battery is doing well in more normal temps, drops to say 40%, and then drops fast, followed by a recharge to 30%,where it discharges slower, maybe because the charging heated it a bit... ? So it's performing a tad better ?
3. Seems less possible that there is a short, but could be a temp sensitive short. I have seen those in electronics and cars, though the initial description has the feel of a battery going south.
If it remains stable to 40% and higher, and either the 40% lower threshold or temp get's it, perhaps changing out the battery would be a safe bet.
Thanks for the reply. I got reading a theory that as the battery ages, internal resistance goes up and when it gets cold it really shows, but who knows. My. Best bet I think is just to replace the battery.
