Hi folks,
My SGS2 is driving me craaaaazy ... i'm on KE2 with root and arabic patch from madmack ... i discharged the battery a couple of times on this firmware to recalibrate it and even tried a hard reset but nothing seems working at all.
everything seems normal except the battery and voice calls percentage which i only spoke for like 15 mins and percentage all the way up to 74%. With only one hour on the battery, it goes from 90% to 86% on idle. I need help guys.
PS: sorry for my bad english.
From what I understand you are saying that after an hour of using battery power, a 15min phone calls is showing up as 74% battery usage.
This seems completely normal to me...
I think quite a few people are failing to grasp the concept of percentages.
..or is it me?
all i meant was that my phone battery doesn't hold on for a hole day and this is a proof >>

we can't help you because that's normal. i get the same sort of performance.
it's not a defect, it's a feature.
I wont say thats normal at all, i own an galaxy s 2 myself and i cant get more then 4 hours of usage from full battery(no auto sync and data on only when i need it). If you had a ****ty phone before galaxy that doesn't mean 4 hours of usage is normal.
Here's what we should be expecting...
I hope mine gets these results. Only 2 charges for me so far.

thanks for replies ... i reflashed the KE2 ROM again at a full charge ... did a hard reset, changed wallpaper to black, wifi ,BT and data is off. i will test and report back the result.
I bought the samsung s2 primarily because of the amazing reviews it got for battery life.
I got mine 2 days ago and right from the start there were problems. I charged the unit three hours and according to the battery meter it had still not charged. then I tried to turn on the phone nevertheless, and it said it had 100% battery life. I then used it for 2 mins and it dropped down to 0% again and powered down. Then on charge back up to 100% in a couple of moments and back down to 0 % mins later. I took the battery out then put it back in - and then it was working fine again.
Now on day two, I've noticed an immense drain when its in use. Check out the screenshots. I think I'd be lucky to get two hours solid use out of it.
Should I return it, or does this look standard?
The battery needs some time before it reaches it full potential. In the mean time do some searching cause there already are enough battery life threads.
I already searched and read many of the other battery threads but didnt come across anyone who'd experienced the problem I described.

Correct 0-100% about four hours longer on a brand new phone ,
then I tried to turn on the phone nevertheless, and it said it had 100% battery life. I then used it for 2 mins and it dropped down to 0% again and powered down. Then on charge back up to 100% in a couple of moments and back down to 0 % mins later. I took the battery out then put it back in - and then it was working fine again.
bad battery connections clean .
Now on day two - I charged it at 9pm last night and by 9.30 am unplugged it was down to 84%. This with no apps open, no widgets running - nothing. wifi was active though.
Overnight is variable and Wifi uses battery .
then in using it for just 40 mins - doing nothing more than internet surfing through wifi; it drops from 84 - 68%.
Does this pace of battery power loss sound consistant with other users experiences, or should I return the unit and ask for a new one?
I think you have two choices one charge the battery read all the battery posts .
Or return to seller .
Personally i would turn WiFi GPS etc off at night charge phone to 100% see what it drops to by morning .Big drop and it would be returned as your original 100% to 0 drop very quickly suggests a possible fault .

Thanks for your feedback.
I've read through quite a few posts there.
One thing; do we know how long galaxy s2 should be able to be on for if the screen was on the whole time? Is four hours low, or does that sound right??
50% or less on brightness playing SD video should last more then 7 hours , browsing web however can be 5ish+ .
Screen at 100% and browsing web drains battery fast , 4 sounds about right.
It all depends what and how you doing it ?
Well I have it on auto brightness, usually which seems to be around 50%....
and I'm web browsing or just playing around with settings and looking at menus. I'm down to 45% battery and have probably had the screen lit up for maybe 90 mins max??
rest of the time phone has been on idle with wifi on but no network activity...
does this sound below what it shoudl be??
OK I've now attached my screenshot.
Does this battery usage seem normal??
i.e, such extreme drops when the phone is in active use???
All I've been doing is texting, some wifi surfing, and looking at menus.
Search the forum for "Android OS bug". There's no solution yet though. Turning wifi off when you're not using it helps.

Hi there.
I have installed Lite’ning Rom v1.5. Everything is working ok, but yesterday before sleeping I had battery 80 %, today after 6 h it drops to 1 %. I have data transfer turned off, also Gps, WiFi, ... Also before 2 weeks it drops from 100 % to 70 % after some hours with no using.
I have to add, that my battery held up for 4 days once with no particular using.
Any ideas plz?
Thx for answer.
This is a post from the Xperia play forum about battery life. Since the new Xperia phones shares a common software maybe the Mini is affected too?
http://forum.xda-developers.com/showthread.php?t=1238230
I'm gonna try and see if there is any difference for me on the sk17i.
good idea
nice, please let me know if there will be some difference for sk17i
thanks
well i tried it, and im sorry to say that ... but it doent change anything
Let me here give you and example of how bad is this phone battery situation is .
I have an HTC HD2 running android 2.3.3 and it has a 1GHZ processor which is the same with the xperia mini pro i bought , on the other hand the HD2 has 4.3" screen while the mini pro is only 3" so I already nticed after using the mini pro that its consuming so much battery than the HD2 but i wanted to be more specific so below are the details
HD2 Battery is 1230mA, xperia mini pro 1200mA ( Almost the same )
so I left both of them in idle for 8 hours ( wifi is on both have the same apps like facebook , google+, twitter, with the same update settings, )
the HD2 dropped from 82% to 71% in 8 hours in idle (Lost 11% )
The mini pro dropped from 100% to 50% in 8 hours in idle ( lost 50%)
for me this is a big gap between the two devices and to be honest i expected the HD2 to have a shorted battery life conidering its much more powerfull device and its 2 years old with the same 2 years old battery.
and i also noticed that during the test:
the HD2 never exceeded 10mAh consumption at all
the mini pro rarely went below 50mAh and the minimum was 26mAh
so i guess there is something that eats the battery during the idle time and it is taking alot of it comparing the two devices.
in fact when i bought the mini pro i wanted smaller device that will have a better battery life , but now its totally the opposit which make me confused.

I have been struggling a bit too with battery life. But with my current settings I have 21hours since charge and I'm on 65%. (so thats about 2.1% each hour) But thats not standby only. I have been using connectbot, some browsing, facebooking, whatsapp.
wifi on all the time and push enabled for activesyncemail, facebook+googleplus+twitter notifications, whatsapp messages and gmail.
I have disabled 3G and set my operator manually and most important of all I have unchecked the Allow wireless network-option in Location and security.
Did attach two screenshots showing the battery usage. I had to connect the USB-cable to take those (with ddms) so it did charge for a minute or so (same thing abit earlier so it shows a small charge period for 1-2 min)
A bit funny also that it shows battery gain in two places (which wasn't when I had the device USB-plugged) and also it looks like something has been keeping the phone awake while the screen hasn't been on.
But as you say it's not very often down to 10mAh as you get on the HD2. (3rd screenshot)

WOW i really envy you now , i should find whats making mine drop that fast in idle while yours can last that long while using it. i will check the settings you specified and report back the results
I attached a screenshot of the HD2 idle usage
Wifi
I've found that the culprit for mine is the Wifi.
I went from ~8 hours to 32,5 hours(is just about to turn itself off) by turning wifi off and on only when I used it.
This is with me watching a 40 min mkv show, and playing myth defence for 30 minutes and a little talk and sms and searching the market.
Wifi location function has been off from the start.
It's a bit weird because on the x10 mini it turned off wifi when the screen timed out and it held for about the same time, so maybe it's a "feature" they forgot to implement on this phone.
On normal usage mine lasts max of 2 days and thats pushing it. Normal use means I do browsing on it via wifi for maybe 10 minutes at a time per hour I guess. Will sync to wifi every 15 mins for 1 minute then off (via Green Power app). To help the thing, I am downclocked to 122Mhz on idle, max to 800+ on load via SetCPU, always on minimum brightness. Playing with autostarts too to disable apps to run and eat memory as well.
There is a higher capacity battery thread

At 10% the phone suddenly dropped to 1% and it did shutdown.
Something is draining the battery during the sleep and i cant find it.

Yes, this thing happens to me, 30% them immediately 1% and stays on for maybe 2-3 mins then dies (when in heavy use). I will recalibrate the battery stats when the phone is fully cycle charged (drained to dead, and charge on AC overnight). Hopefully should fix the issue.

Check the battery usage what consumes it (Settings, About Phone, Battery use).

yeah. it died again at about 10%, I did plug the charger and switched on the phone and it went directly to 10% again. Unplugged it and it died after a few mins. Did pull out the battery and inserted it again and now it started to behave correctly starting from 1%.
Another thing I have noticed is that when it reaches 100% it starts to discharge until it goes down to 95% then it charges again (quite normal behavior) but the phone still shows 100%. So it could be down at 95% when you disconnect it but it starts to tick down from 100%. I did check the kernel source and it was a comment there that it should show 100% while still charging in that mode.
It's possible to see the real value when using adb logcat|grep charge and also betterbatterystats shows the real value instead of the 100%.
thanks for the tip will try that. i get that same thing too, dies at 30% but when charged, it goes up at 30% immediately hehe... well, i didn't went to extent remove the battery though. what i do know is to have "Battery Monitor" sound some notification at 3425mA. At that rating, that just means I have some time to look for the cable and charge it.
Side by side, the st15i screen is significantly brighter than the st18i screen at the same brightness level. Though the st18i has a higher resolution, its colors appear more washed out, in a way though that is easy on the eyes. The st15i seems to be brighter and perhaps that is hurting the battery life.
Upon further testing, it appears the auto brightness feature of the stock rom is doing this.
With both devices in a dark environment, the st18i appeared brighter, with the same brightness settings.
Unfortunately, there doesnt seem to be a way to turn off auto brightness on the stock rom.
My mini pro's battery last much longer then it did on my old phone galaxy s2 so I have not a problem with battery

I'm currently on almost 2 days since charge and on 8%. And just when I started writing this it did just go down to 1% and a warning that battery is almost dead.
So it become 2% "better" ;-)
But I'm still happy with almost 2d with mixed usage and standby (wifi,push etc all the time).
Hi
I bought this phone 2 week ago. already when my phone was in sleep with airplane mod , the percent of my battery was instant about 10 hours. but now when my phone is sleep with airplane mod and i dont use it , the percent of battery is decrease about 10 percent in 10 hours. i do factor reset. but the problem was not solved. i guess when i update the phone in update center, this problem was appeared. now the version of my phone is :
android version : 4.4.2
software version: V10c-AME-XX
how i can solve this problem? and how i can to return to my first version software and cancel my update?
Try getting your previous rom and flashing that, it might just work

I don't think Your issue is software-related. I've got my Mini for over a month now, and I was dissapointed about battery life on it's first days. Now I think battery shaped its own and there's no problem with battery at all - it lasts two days with moderate data usage.

How long did it take for the problem to solve itself?
I got my phone about a week ago and I was suprised that it was able to last almost 3 days before charging.
Currently battery life is just terrible (less than 24 hours while phone is practically idle, with low brighntness, disabled gps, wifi and data connection) which is quite strange because since then I have rooted my phone and got rid of bloatware.
I have read somewhere that you shouldn't allow li-ion batteries to discharge fully, unfortunately I did that unintentionally,
Is it possible that a single full depletion managed to damage the battery? Or is it possible that I deleted some crucial app?
Phone's electronics and software will protect the battery, so no worry about discharging.
Did you install any messaging app (WhatsApp, Viber, Skype, Tango, Facebook or similar)?
These are draining battery a lot.
No. I don't use those. I even greenified dropbox, pocket and some other apps,
I installed Busybox (I don't know if this is even relevant, honestly I have no idea what am I doing,
I just follow guides to achieve functionality I want )

I don't use custom ROM's, after factory reset my phone isn't even rooted. I'll check out BBS soon and post some logs, they might shed some light on the issue. Built in battery usage app shows that most of the battery (30-40%) is sucked by Android OS
Factory reset did help indeed but not for long, battery worked like a charm for 3 or 4 days but problem reappeared.
We lg mini g2 two weeks and never more battery lasted 24 hours on average use. I see that most say the battery should take 2-3 days with average use but to me you is not no day. After 2 hours of Internet browsing still remain less than 50% battery. Is it normal? What will keep you battery continuous internet browsing?

It depends on your usage and brightness settings.
Normally I keep my brightness below 40%.
If I play ingress in the sun with display at 100% brightness I will get the same results as you do.
Device: Samsung Galaxy S2 (GT-I9100) T-mobile carrier- unlocked, Rooted ,Running stock rom with a Philz touch recovery
Problem occurred after about a week of purchasing a new battery since the old one got swelled... but i have two brand new batteries now both are not original but good quality (1 Year Warranty) With both batteries I had the Problem
Let me explain the problem :
______________________
Device would go off in at a certain battery level from 30%-50% (as for my experience):fingers-crossed:
To turn the device ON plugging in is compulsory... but then the battery would be Completely drained..
Also if you try to do a restart at a battery level which is closer to the sudden death the after re boot the battery will be at a extremely low level and wont rise...
I searched all of i can to find a cure to this because the last thing u expect in a situation is your phone dying?
Apparently the problem seems to be that the phone is reading the battery wrong? about a 40% so simple do a calibration Nope Nothing not even a change...
Here is what I tried
_________________
Calibration Methods - Apps and manualy
Reset the device
Let the battery chip reset
and all other methods
but finally i decided to reflash another stock rom :silly:
and I Downloaded This file I9100XWLSD_I9100XENLS1_XEN Since it was a Genuine Netherlands version but i decided not to go with T mobile this time:fingers-crossed:
I Wiped all the phone in Recovery then went to download mode and using Odin V1.85 I flashed the stock rom:fingers-crossed:
Turned it on using a Fully charged battery that i charged separately and i used it for some time max brightness max vol radio and gps wifi bluetooth etc. to drain the battery and at 38% phone started to flicker and turned off again:crying: (no Sim or Memory inserted no apps downloaded)
But i decided to go again i plugged it in ( never changed the batt) and let it charge for about 95% and turned all on again and this time i put on my simcard and memory and did all what i did except that i downloaded whats app and instagram. and also when it reached below 55% i Played some music and locked the phone (NO SCREEN LOCK USED) and after some time i checked batt was at 38% :fingers-crossed: immediately i locked it back and left it again....
Viola !!!!!!!:laugh: last time i checked it was 15% low batt warning came ( haven't seen it in weeks) and then the battery drop was a bit fast and at 12% the screen got a little flicker so i plugged it in.. I think the problem is halfway solved, ill let the battery go some cycles and update soon.. also i will attach some screen shots off the battery level too and take a close look at the time and battery level after 15% on the pics
:victory:

So yesterday I plugged the device until it reached about 85% and unplugged it when I was going to sleep, and at about 8 o'clock this morning i noticed that the battery level has risen to 96% , I think that is because the phone slowly gets to know the battery level correctly.. and right now it 11.08 am and I had turned on Mobile Hotspot and Data from 8 am , battery level is 82%.
I'll update again tonight when the battery drains completely

Can you also share the SoT ? I know it depends on how a person uses the phone but still I want to have an idea. I might also try this to have a better battery life. I also once tried that exact stock rom but without even charging completely, I went on to another ROM. So I am gonna give it another try today . :good:

Hello Eren ! Whats SoT? and you also have the same problem?
So... Now the problem is still there.....
Phone went off at 43% and also figured that there has been a near vertical drop of battery from 40 % to 12% and thats when the device was standby,
phone goes off only when im using it?
Can a Expert please look into this matter and help me please. looks like all what I did has been useless

I have the same problem. when I reboot my device in most of cases the battry level showed is a 10/30% lower than before and also my phone shuts off showing 10% percent or less and the sreen brightness goes a bit crazy for 2 secs before it shuts off. I have the original Samsung battery but I also bought the 2000mAh extended kit but now this issue happens in both of them I've read that I have to callibrate battery so I will try this and post results
1. Turn off your phone.
2. Fully Charge.
3. When getting 100% signal, unplug quickly.
4. Pull off the battery and put it anywhere.
5. Wait for 180 seconds exactly (be careful )
6. Meanwhile, take this opportunity to dust off the internal compartment.
7. Put back the battery on the right side.
8. Turn on the phone.
9. Pray the Battery god
10. ... and voilà !

I did it and my results were this. My phone shuts off at 5%, slightly less than other times. I rebooted it once while 80% percent and remained the same. Battery lasted 2h and 40 mins with medium/high usage
I would say it fixed something for me but not a lot. Now im going to try it with the 2000mAh samsung battery
Edit1: now after another full cycle the battery lasted for more or less 3 hours with medium usage and shutted off at 8% now im going to try on my 2000mAh battery that had an 8% and it shutted of normally with the shutting off screen and without weird screen brightness tweaks

Well I think it worked for you because you had a Original Samsung Battery Right?
In SL a Original batt would only come with the phone :crying: Fakes have invaded,,
So i read some where that fakes dont have the original capacity? so if it is then it would match perfectly !
so now im in hunt of a original hopefully this is not a phone problem
No its not definetly a phone problem and it isn't a big deal to find an original samsung battery for sgs2 however the Samsung 2000 mAh battery kit its waay harder to find and the ones that I found are more expensive than when it came out
Yeah, I definitely think the problem is with your battery, so you just need to replace it.
Btw guys, what is your general Screen on Time with your standard 1650mah battery (not extended)? I'm running CM13 and I barely get 2h on a single charge, but then I read reviews from the early days of S2 and for instance here they have 4h24 browsing time (with screen at 50% brightness) or 8h video playback.
Is it all related to being a different ROM, or my battery just needs a retirement? Being a different ROM would impact so much on the Screen on Time? Also, I have auto-brightness always enabled, would that have such a significant impact?
Greetings
EDIT: Since I generally use the phone indoors I don't think that would be the difference in such a different Screen on Time

With 1650 mAh and on CM13 nightlies, my best so far is 2h and 28 mins with brightness at between %0 and %25 and only wifi is on.
That 4 hour SoT is probably on gingerbread though.

Being gingerbread would make so much of a difference? It's like twice as much SoT...
Thanks anyways

Never used SGS2 on gingerbread but it is possible I think. I remember reading on forums that people started to get worse battery life with ICS and with JB it got even worse. So yeah probably possible.

Hi Bolshoi! I will definetly update the SOT on the stock rom after the new battery arrives! I asked one of my friends who is in Netherlands to buy and send me a batt. Regards!

Im From Sri Lanka Achimakulo its so rare to find a Genuine Samsung battery for a older device like mine and even if i found one its either old or way too much priced
I think its because my device is so rare in this country
Is it fixed now??
See attachment
battery level drop is natural? ?
