Stability Test drained 100% battery on charge! - Galaxy S II Q&A, Help & Troubleshooting

S2 on Telstra Australia
Suspect RAM problems due to random reboots so I wanted to run a RAM test
Last night battery was on 100% but still plugged it in to wall charger
Kicked off Stability Test and went to sleep
Woke up this morning to find it ran for 5 hours 7 minutes before the phone shut down due to a drained battery!
So running stability test was draining the battery quicker than it could recharge! Of course the screen is on 100% of the time time because it says not to run the the stability test app in background or while on standby but should this happen?? Should it drain that much??
Will try again tonight with everything turned off and see if I can get the test to run longer..

The phone is able to drain more power than it gets through the charger, yes.

Thanks yeah well I have just tested it again and yeah battery was at 96% but most services still running on the phone so I kicked off the stability test for 10 minutes and noticed the phone dropped to 92%!
So I then turned off wifi, bluetooth, sycing and screen brightness and ran again. Battery was at 96% ran for 10 minutes battery remained at 96% afterwards so it was keeping up.
I thought I could further optimise it so I turned data off, cleared the ram and closed all running applications and tried again. This time battery dipped down to 88% after 10 minutes.. wtf!! I guess it's true about you shouldnt force close apps that are idle, let android handle them itself, also is it maybe because data was turned off some widgets or apps might be doing a constant connection retry and it keeps timing out? I can't explain why it would drop like 8% when I turned off a lot more stuff..

You do know that StabilityTest is supposed to stress your CPU 100% and by doing that it uses up pretty much maximum amount of power? No realistic app uses up that much power. It's useless to run StabilityTest for longer than 30 minutes tops, if you are overclocking (I guess that's why you're testing) I find 15 minutes stable is good enough for 99.9% stability in real life apps and daily use.

Hmm well I was running the test to check my ram because I've had a few random reboots. The instructions for the app say most problems can show themselves within 15 minutes of testing but it said sometimes it took close to 5 hours for the reboot to occur revealing the ram was dodgy so this is what I was trying to achieve by running it overnight

Ridiculous Battery Life

I previously made a thread regarding low battery life.
After a week of use and more testing, here's what I gathered.
(Note: I have GPS, Bluetooth, Wifi always disabled, brightness lowest)
My phone will completely drain out in 6-7 hours.
I found the culprit: Cell Standby
1.) Cell Standby always uses the most battery, often 60%+.
2.) Phone Idle often follows with 30%+.
So, to verify my theory that the screen isn't the issue, I turned on airplane mode.
I proceeded to watch a 1 hour comedy, and battery life dropped from 60% to 50%.
This is lower battery usage than if it were sleeping with cellphone on.
I then noticed that my signal hasn't been good (provider sucks, no choice, all of em here sucks).
So, I placed my phone on, but asleep inside a locker for 2 hours (no signal).
When I took it out, it was very warm at 40+ C and battery life dropped about 20-30% per hour.
I've tried turning 3G off, turning always-connected off or downgrading 2g.
The result has always been the same. It still sucks bigtime.
It seems like Nexus One also has this problem, anyone notice similar problems?
I've googled and been told that this is "normal", because the phone increases power to secure a signal.
However, I've clearly owned phones and placed them in signal-less lockers prior to this, and trust me when I say most of them drop 5% per hour max.
20-30% per hour is horrible, and clearly the phone is overpowering its components.
There are some certain Radios you can flash to improve how your phone uses power to pick up a signal, Requires root access tho.
Can you please point me to those radios? I've already tried updating my radio to latest.
My phone is already rooted.
My battery is a joke and I have tried many different things. I always have to charge it by around 3pm everyday during week as It will almost die on way home.
I take it of charge at 7.30am by 9.30 it could be down to 86% and then it judt continues to drop by 3 It can be between 60 and 50% if lucky, by time i'm tenmins from my house I get 15% and warnings.
I use basically for txt, some net usage and sometimes playing a game 10 - 20 mins tops and or read ten mins of books.
I have all updates off only manual and screen down low etc - doing my head in!

Strange, I always have 3g on, and still play a lot with my hero (games and such)
Still it survives about 36 hours on 1 battery load. Without 3g it holds out for 72 hours.
Post #1 on the thread below seems to have a working solution (re-interpreted below)
It seems to be something to do with the battery stats and charging via usb through PC instead of via the mains.
You have to clear your battery data when your phone has really really low battery (this is probably the MOST IMPORTANT step) (you can do this through recovery mode in amonRa). Once the battery data is clear, switch back on (before plugging in) and drain the battery so that your phone switches off by itself (playing music loud and switching wifi, data connect etc, etc is suggested in the thread).
Once battery has died, plug in your phone WHILE it is STILL OFF, then when the battery shows green (will probably take longer to charge because this time it is getting a full charge), UNPLUG BEFORE you switch it on. and you should notice the significant difference. - Oh yeah make sure you switch off all those data connections and wifi and all those other things that you used to drain the battery - unless you use some of them of course
EXTRA TIP given on the thread: TIP!! Remeber when changing and flashing new roms to unplug the phone from charge *(i.e. unplug from your PC) (edit Bad4ss) * after you boot!
TO answer LennyUK's Q below ( and so that the next page doesn't start to quickly before this suggestion is read ) I think why it is suggested for the first boot after this process to be done while off is because it is already off because of the drain AND because it will get a clean full charge up for the first time after a battery data wipe. Because while it is on it will be depleting the battery even if it is in a small way - after that you can do it whichever way you want *nudge-nudge-wink-wink-say-no-more*

I don't see why the same thing cannot be achieved by charging with the phone on, just as long as you don't change between phone being on or off during the charge i.e. if you start charging with the phone on leave it like that the whole time and visa versa

Can you do this on non rooted phone? How do I get into recovery mode?
I think the analysis is flawed. I also think the stats information doesn't tell you everything. For example, yesterday I had 60% cell standby, 20% WiFi, 20% phone idle. Consumption was 45% in 24 hours.
Previous to yesterday, I had high battery consumption. So yesterday was a breakthrough but YMMV. I removed the PCSCII and the Mail app (I don't sync with Exchange and I don't sync with a PC as such - I don't run Windows). I also disabled auto task killer. I rebooted without being connected via USB to power or to PC. Suddenly power consumption became similar to Modaco ROMs.
Last night, I also disabled the setCPU application and rebooted. 6% battery consumption in 9 hours. 34% cell standby, 33% WiFi, 33% phone idle. Consumption was 45% in 24 hours.
how have you improved battery usage, ive tried resetting battery stats, draining battery, fully charging, using kimera 1.5 and with no wifi no bluetooth, not using phone in few hours it was down to 63% and in 10mins had dropped to 59%
i had similar battery problems but today i changed radio versions into a different one, now i get almost full signal all the time and battery usage is geatly increased (went down 2% in 4 hours as compared to 10%/hour)
so i suggest finding a radio that give you good reception

63.18.55.06JU_6.35.08.29
made alot of diference
you should ty out diferent radios and find one that gives the best reception, it will be different for different providers and countries

i unplugged my phone from the charger after doing this at 6am, it had 100% charge
its now10:45 pm, i have 44%charge left...its crazy
before i used to run out of juice around 10 hours after i charged my phone, its not been almost 17 hous and i got 45% left
i seriously suggest doing this

I will use that radio too seeing as I too am on T-Mobile in the UK. When you say to use the link and suggest doing it, I take it you mean the "get to 10% -> get to recovery mode -> wipe battery info -> reboot and drain battery 'til off -> charge while off and the take off charger once charged and switch on..
'cos I tried that and still having problems - am using the new Villain 4.0 beta2, so maybe the radio change in combination to this is what will work - I'll try it tonight when I get home.
immya : many thanks i now hove phone back
flashed radio 63.18.55.06_6.35.05.31
and lost 1% over night
previously on LOST
radio 63.18.55.06JU_6.35.09.26 lost 56% overnight
perhaps issue with 2.1 roms is the latest radio and not latest kernal
BTW using sensehero at moment as was trying 1.5 roms to get better battery, and that didnt work.
some one maybe sticky this info , if anymore find it a saviour. will report back after work, mayeven be able to use data syncing again

[Q] Device runs at 61 degrees during full load

Have a Telstra S2 on stock carrier ROM
Experiencing random reboots sometimes even on idle.
Last night I ran stability test to check for RAM and actually the test ran for 5 hours before the battery ran out even though my device was fully charged the beginning and connected to the wall charger
However the device got to 61 degrees temperature!
I emailed the dev and he said its a concern the device is getting that hot and that also that the battery is draining that quickly that it can't keep to keep device charged.
Suggests I should RMA it. What do you guys think?
You stressed the device to it's maximum extent and it ran for 5 hours, so 61°C is VERY NORMAL IMO. No question of RMA and else. And also that is the temperature of the Battery, if that were of CPU I'd like it too
Regards.

Yeah ok that seems fair enough but still I am troubled by these random reboots which I still think I am going to need to RMA for? Shouldn't be happening should they?
Still has the huge battery drain though even when not running the stability test
After you have had the battery drain for a few hours, post up a screenshot of the battery usage page.

battery problem awake while phone is idle

So I have narrowed down why my battery dies even when I'm not using my phone...for some reason when I look at the stats under battery usage, the battery seems to be awake almost 60 to 70 percent of the time, EVEN when I'm not using the phone...my battery lasted a total of 15 hours...I made a 20 minute phone call and screen usage was 25 minutes on lowest settings....4g was on wifi was on...automatic background data was off...gps on....everything else was off....why is the phone waking when it is not being used???? any way to find out?

Have you tried restarting your phone and then tracking the battery usage?
Just my .02 here, I installed Earth HD live wallpaper and the phone went crazy. I keep it plugged into my laptop during the day and noticed that the battery was slowly draining instead of maintaining, not much only a couple of percent. Toward the end of the day I noticed the the battery charge was in the 50% range and dropping fast, you could see the go down so I did a reboot and the charge came back at 4%. So you may want to look at what you have installed and try removing apps that may cause issues. I removed the app and now no problems, I'm also using Beastmod.

[Q] Battery dying extremele fast on CM9, any fix?

Before flashing CM9 to my mopho I had only used the stock rom, on Gingerbread my battery would last for 1.5 or 2 days, but since i updated to ICS it dies whitin 10~ hours of idle...
it usually goes from 100 to 70% overnight (6 hours). Recently I purchased Juice Defender Ultimate hoping it would help fix this issue, well... it did help but id didnt solve it, went from 30% overnight battery drain to 15-20% with airplane mode enabled in JDUltimate.. wich is ALOT from what i've read most users are getting (1-2% overnight, am i right?).
I've wiped my battery stats over and over (even tried the market app method) and nothing has changed.
I installed BetterBatteryStats and Watchdog from market, and both of them and the android battery stats show that "suspend" or phone idle are the cause of my battery dying so fast.
If anyone experienced anything similar and knows a way to fix this I would really appreciate it!!
Ive never seen my Photon go overnight with only a literally 1-2 percentage loss.. Not on stock, Cybiks CM7, or on CM9. but it usually only drains maybe 10 or 15 percent on higher end so nothing major. Talking ~8 hours off charger idle with random text or two and led going nuts blinking all night with data/wifi/bluetooth etc off but NOT in airplane mode. Are you on latest CM9 build? My bet is you have a random app screwing with phone keeping it from entering sleep mode or whatever its called. Check the "Awake" time under the battery settings to see if the awake time is allot higher than the "Screen off".
I have the same problem, no matter what kernel, no matter what cm9 build, still draining too much in idle. I know, others don't have such draining. But I give up and I am back on cm7, where everything seems fine.
I noticed that this happens to me as well. Previously, I fixed this by re-calibrating the battery. Now I was suspecting skype, but it is not causing this. I have noticed that having both GPRS/3G enabled and Wi-Fi drains power very quickly (about 4 times faster than having only one of those switched on). I'm using Photon in Europe in GSM network, so not sure is it the same with CDMA.

during night, "Awake" seems to be up about 50-60% of the time, a lot more than "screen on"
I´ve read that setting your phone to "never turn screen off" shuts down suspend process and battery actually lasts longer, has anybody tried this??
Are you guys logged into Latitude? I signed out of it yesterday and now after 10 hours on battery, although 6 of it was sleeping, I still had 86% left.

I am not sure, but never logged in latitude myself, so I think, no.
And CPU was perfectly sleeping with turned off screen. But still the same draining. And what I know, it has nothing with gsm.
I as well am having the same problem, dropped from 88% to 72% within 20 minutes.
phone idles killing my battery at 50% any fixes?

[Q] Samsung GS Wifi 5.0 Battery Charging

Hi everyone i have been using wifi 5.0 about 3 months now it satisfied me enough and i am sure will continue. But the only issue which makes me unhappy is when i am gaming or using gps battery finishes rapidly. I would like to learn when to charge the device is 25% ok and when i am using it on charge even when its full is it bad for the battery life?
Yes you should unplug it when it gets full.

don't leave it on the charger longer then 20-30 minutes after it reaches 100%, any longer can be damaging to the battery if done repeatedly.
Wish these chargers were more like the motorola ecomoto chargers that cut off charging automaticaly once the battery hits capacity.

Thank you for your answer but every time i am charging it over nights i am always turning it off and go to sleep what i want to say i cant wait to be 100% then sleep is there any app to stop charging when its fully done. And isnt it ok while gaming o keep the charger cuz u know after playing 1 hour of fifa12 battery nearly going dead? thanks again.

stopping charging has to be done within the charger itself, so no there is no app that can stop it, plus apps couldn't do anything when the device is powered down anyway.
An hour of a game kills your battery? I can play atleast an hour probably closer to 2 of angry birds and thats from less then 30% and i'm on the 4.0 player which has a much smaller battery, sounds like you've got some battery drain issues to work thru.

yeah u are right about apps no way any app to work when the device off.
I mean maybe 1h and 20 min. with 50% brightness on and i guess fifa use more data than angry birds when ur playing.
anyway its important to know that i shouldn't keep charger on when its 100% because usually when i am home i was using it like that thanks again.
do u think the app called 'sense analog' may make the battery life shorter.
Something is definately wrong, because I can play MC3, which is even more intensive the FIFA on my Gplayer 4.0 for more than 1.5 hours and still have some life left, and the Gplayer 4.0 is only rated for 4/5 hrs and yours is rated for over eight!
After a full recharge, while still plugged in download battery calibration from the market, and follow it's instructions, after you do, while STILL plugged in, reboot. After a full reboot, unplug it, and DO NOT REBOOT until your gplayer completely dies (forces shutdown). Once that occurs, plug it in, let it charge to 100% (while on), leave at 100% for about 15 minutes, unplug, and use as normal. That should fix your issue, unless your battery is dying, which should not occur, even if you are abusing it badly, for awhile longer.

haven't seen the 5.0 screen in person but if the brightness levels are anything like the 4.0 why do you have it so high? My brightness is at like 15-20% with autobrightness OFF.
First, like many others already said, it sounds like something is wrong with your battery. I'm on a 4.0 and playing two hours of a really intense 3D game with auto-brightness indoors will bring the battery from 100% to 50% (maybe it even uses less battery).
Second, as to how to conserve battery life, Rule #1 (as others have said): definetely do not keep it plugged it at 100% for too long. Then, something I tried on my iPod and have been using ever since: keep the battery between 50% and 100%, and once a month, completely empty the battery (until it shuts down) and after that charge it to 100% (this is called a charge cycle). As to my iPod's battery, before I was using this, the battery life got shorter and shorter, but after, it didn't shorten noticeably anymore. On the computer I'm writing this on, for a couple of months, I barely followed this plan, and I lost about 5% of my battery capacity (I have a battery widget that tells me what the total capacity is) within one or two months, but then I started following it a little more closely, and actually got some of it back. Over six months later now, I have lost about 10% of my battery capacity (from the original capacity), except that I should do a charge cycle in the next couple of days, and the last time I did a charge cycle, I got about 5% of the original capacity back, not to mention I have broken rule #1 probably too often and for way too long, often for several hours
My 5.0 can play games for hours before it dies but it has strange batery levels..From 100% to 75% it goes very fast.around 40 minutes when you play game..and then on 75% it stays there for 2hours when you play game and with regular use it can stay all day on 75-70% ..after that it fastly drops to 25% and just when you thing you need to recharge it can stay on 25% forever..you can play 2 more hours of game on 25% or with lighy use it will stay all day on 25%.

This is not correct. NO modern device has ANY smarts in the external charger - nearly all current phones (and every smartphone on the market for the past 3-4 years) has a constant voltage 5.0 volt USB input. Modern "chargers" are not chargers at all - they are dumb 5 volt power supplies, nothing more.
Charging "smarts" are handled by electronics in the device itself and have been for ages. (For all practical purposes, the Player 5.0 is a Galaxy S smartphone minus the cell radio...)
The kernel and charger hardware automatically handle charge termination and restart themselves. This is, for example, why Daily Driver can charge at higher current levels than stock at low battery (but drop the current as the battery reaches nearly full in order to stress the battery less).
Oh, as far as battery percentage display - the method used for estimating state of charge on the Players is abysmally primitive and highly inaccurate.
Battery Charging YP-G70
I always charge my completely standard YP-G70 overnight. As I understand it, the charger only provides voltage and in this case it's 5vdc. The device's battery management software draws the required current to charge the battery. If you install 3c's "Battery Monitor Widget Pro" you can see a charging graph showing the current levels drawn over the full period of charging. The charging current is stepped to control battery temperature and is reduced as the battery approaches full charge. By the time the battery reaches full charge the current draw is down to a trickle charge and will not overcook the battery. I usually leave the device switched on, which further protects it by maintaining a small load. One of the problems I have found with this device is that this charging regime, along with the fairly large capacity of the battery, mean that the battery can take up to six hours to fully charge, which confirms, in my view, that overnight charging is OK.

Something is definately wrong, because I can play MC3, which is even more intensive the FIFA on my Gplayer 4.0 for more than 1.5 hours and still have some life left, and the Gplayer 4.0 is only rated for 4/5 hrs and yours is rated for over eight!
After a full recharge, while still plugged in download battery calibration from the market, and follow it's instructions, after you do, while STILL plugged in, reboot. After a full reboot, unplug it, and DO NOT REBOOT until your gplayer completely dies (forces shutdown). Once that occurs, plug it in, let it charge to 100% (while on), leave at 100% for about 15 minutes, unplug, and use as normal. That should fix your issue, unless your battery is dying, which should not occur, even if you are abusing it badly, for awhile longer.

This is not correct. NO modern device has ANY smarts in the external charger - nearly all current phones (and every smartphone on the market for the past 3-4 years) has a constant voltage 5.0 volt USB input. Modern "chargers" are not chargers at all - they are dumb 5 volt power supplies, nothing more.

First of all thank you for this valuable information, thus I can keep my device on plug while i am driving and using gps otherwise on long distance its annoying to keep checking the battery while driving with gps app on.
Other think is i guess its normal but just to ask, The device becomes really hot on charging while i am gaming. What do u think?
Is there an app that takes time of your battery like today I turned on at lets say 7:00am and the battery dies at 9:00 and you forget the times but the app says how long it lasted. Is there some app like that?

3c's "Battery Monitor Widget Pro" gives all the battery information you could ever need. A data log and graphs allow performance to be analysed over any period of time. You can set markers to indicate charger plugging and unplugging times. Hope this helps.

Gaming = CPU and GPU cranking at full tilt with the display on - of course it's going to get warm.
