Hello
I've been having some battery problems with my sgs2. I've bought it in june of 2011, it is my first smartphone and I was immediately pleased with it. great phone, everything working properly. since it was my first phone I was a light user and the battery could last me 2 days, sometimes it even got to last 3 days. However, at the beginning of the year I felt a sudden drop in battery performance, coming to last only 12-15 hours with light use. by this time I became more of a medium-heavy user and under "normal" use the phone would be dead at 10 hours, maximum.
I bought a new battery, official samsung 2000 mAh, and the performance became slightly better. It would at least last a day of work, but the performance was never as good as the original 1650 mAh battery when I first bought the phone.
by this time I began experimenting with ROMs, ressurection remix, miui, and now pfittech. but as time passes the performance is always dropping and today something strange happened. I locked my phone at 17% of battery, and after a while I checked it and the battery was at 18%. I checked again and is now at 19%. Right now it's 21%. What the hell?
can anyone help me? any help would be much appreciated.
p.s. i've tried calibrating the battery and I've read in the forums that on JB it's not necessary because the phone now clears battery stats when they reach 100%. I've also changed the stats with extweaks to absolutely no effect. I've been reading many topics on this but nothing quite seems to fit my situation.
mate u have to reset gauge in extweak then kill ur battery and pull off for 5 min then charge that should do

Thank you for your advice I will try that. I'll let you know if it works. btw, when you say kill the battery you mean let it drain to zero right? sorry if dumb question, I'm a newb at this hehe
Hello! I bought this phone last month. Since I got it, I've never experienced any problem with it. For four days, I noticed that the battery drains very quickly, without any logical explanation for this. The data connection is turned off, Wi-Fi is turned off. Last evening, I charge it to 100%. This morning,I found it turned off, with 0% battery. What solutions do you have to solve this problem? Have you encountered this problem?

Can you please provide some more details on this?
I.E. What is it plugged into to charge? Laptop, Desktop, AC, etc etc.
- I ask this because I had a phone that would actually consume more power than a USB port could put out. when turning off the laptop, it actually allowed a back drain for some reason, and the next morning the device was dead. (Not this phone)
Also, what applications are running? Any?
Finally, you can try to retrain your battery... Wiping stats does not work, ever. So despite what anyone tells you, don't do it. You're just wasting time. SOURCE
So, how do you retrain your battery? Let it die completely. Then plug it in to charge. Don't use it while it's charging if you can help it. DO NOT remove it from the charger until it's at 100%. Once this is done, use it til it dies on it's own. Then yet again, charge it fully and then go back to your normal use.
In some cases, these batteries can go bad, for various reasons. A quick test, but is not always trustworthy is to spin your battery on either side. If it makes more than 2 full rotations, it's swelling and going out. Replace it.
The best alternative is to take it to a battery shop, and let them put it on a Cadex machine. (Pronounced Kay-Dex) ... This machine will charge and discharge the battery several times over a few hours and truly test the current life -vs- the life it should be. Anything rated less than 80% remaining life should be replaced.
SOURCE: I work here
I charge it only from power outlet, with stock charger.
Trib wrote 5 paragraphs on info you need to provide and you come back with a small sentence? Pretty much if you use your phone a good amount it will only last you a day per charge. Unless you give us an explanation on how fast it is draining it's impossible to even start helping

6 hours 40 minutes from 100% to 10%, and the phone in stand by! Cell standby - 45%, Phone idle - 48%, Screen - 7%
And all this after a hard reset and retrain battery! The battery is almost new (aprox 1 month)!
I want it to make a screen shot of battery drain, but I have no clue how to do that on LG L9...

I hard reset it once again. Now is on charging. After that, I will provide you a screenshot with battery stats. Thank you for your help! I try to borrow an othe battery from an other LG L9 phone to see if is the battery or the phone! I hope to find someone with that kind of phone.

I attached a screenshot. Yesterday I changed the battery. Same problem! I take it this screenshot this morning, after I fully charged the phone ... Same problem, a new battery.
Can you please tell us what applications you have running in the background?
Also deactivate google now.(or the google services in google maps). download and install GSam Battery Monitor and after a cycle tell us what applications are eating your battery the most. It's clear that you either use yout phone(screen on time) allot or there is/are some applications that prevent your phone from going to sleep.
I use battery widget reborn and it shows me wneh the phone woke up,when the phone had the screen on,wi-fi on,gps on. Try it as well.
I also had battery issues when on JB. I downgraded back to ics. It's much more reliable when it comes to battery life. And the performance is about the same.
I don't have any app installed. After i replace the battery, i made a hard reset and I did not installed any app. I will install cpuspy and betterbatterystats for more results. I will back tomorrow. Until than, maybe you can provide me more advices. It can be from a damage sim card?

I guess your signal quality isn't good enough because cell standby is eating up more than 40% of battery. Cell standby in my phone is only around 5%..

I removed the sim card, but in flight mode is the same problem... The last solution is to change the rom with a custom one. Any recomandation?
It's not that. Not the signal. It's the firmware. JB has these problems. In ICS Display is the major consumer followed by Phone Idle and Cell Standby.
I also had these problems in JB and reverted back to ICS .
I would advise you to install CM 10.1 on the phone. The battery life is better than stock. I get around 12-16 hours normally. The latest RC4 has fixed almost all the bugs present in older CM 10.1 variations. Give it a try.
I will root the phone and I will give a try with CM 10.1 or I revert to 4.0.4. If all this will be for nothing, I will sell the phone!

On ICS you will get great battery life Telling from my experience as i have reverted back to ICS after trying JB and CM 10.1( both have very poor battery life ) . So instead of wasting time just flash ICS and forget about battery issue :good:
Where can I find a tutorial to revert to ICS?
Same question. Can some one please give a step by step guide on how to revert to ics for l9
Sent from my LG-P765 using Tapatalk 2
Use the offline flash..
I also reverted to ICS and the battery drain keeps like a countdown
I have the p769, and I offline flashed up to V20D (and rooted). Removed some tmobile bloat, and I have pretty decent battery life. I guess I'm lucky.

Hey,guys.My dad recently give away his Galaxy S2,and I updated it to 4.1.2 android JB.I noticed that the battery drains faster than on ginger bread,I looked at the battery stats and it shows that the screen uses 44% of battery.Next day I checked it showed 56%.Is it normal?
BTW I went to bed when my phone battery was 89%.When I woke up it was 79%.I did the battery calibration by charging to 100% taking off the battery and putting it back on after 5min.But I don't see the difference after that.Please help!

Yes it's normal.Jb hogs on battery .You can follow the many battery saving tips that have been posted.If you came from GB i figure your battery must be pretty old.It might require a replacement.

Thanks very much, the phone is 2 years old probably I will replace the battery
i am just new to Android and suprised how dull the display is on my S2 at its lowest setting. Coming from Blackberry where my device was always at 10% brightness. its seems that blackberrys were brighter than my S2, both on the lowest settings.
That being said, i now have my S2 at full brightness and the battery drain is worse than i expected it to be. a small thing when the OS is so good and the whole phone works so fast. i was living in the dark ages. lol.
My device is 39% for screen and so maybe a new battery for you may help. make sure you get a official S2 battery and not a cheaper one from Ebay of that. found the cheap one to have low capaicty even if they say that they are the same or higher than the official ones.

i have the same problem and it isnt a battery problem.
sorry but what is the "solution"? thread is marked as solved... id like to know about this battery drain issue on 4.1.2
Hello all
I am using Mega 5.8 for 15 days now, everything is great. . Battery too is fine works for the whole day and some more but I find it strange that after reaching 20% the battery dies within minutes and phone shuts down. I thought that might be due to new battery but after 10+ recharge cycles this behavior have not changed.
Can anyone confirm that its a common thing with Mega 5.8 or there's some issue with my device.
Also while we are at it any idea when we might get 4.3 update for Mega?
Thankd

If you have root you can use Battery calibration app from the Play store.

Thanks for the heads up gx3k , but just to clarify i am not new to rooting . Have galaxy S2 which is full blown modified .
I downloaded battery calib app and deleted stats like 10 times...tried to manually delete the stats bin folder....but nothing has worked . I feel the culprit is the rom .
Haven't rooted the phone but don't believe this to be a calibration issue.
May be its firmware but how to confirm unless we get an update.

Same problem with me
Just try this . One you are in middle of your discharge like around 50% just remove the battery for 20 secs and put it back . You will see in battery you have already lost 10-12% of battery . I think this is the case of either wrong battery reporting or bad batteries. Just have to wait for a custom rom to cross check this .
GalaxyMega 5.8 battery life
Same thing here. Already tried calibration. Didn't help.
Was charging it. Removed it from the charger at 60%, I removed the battery and put it back in. The battery % then showed 74%.

Yes definitely there is a problem. Battery was at 31% then I removed battery and put it back. It dropped to 8%. had to connect it to charger.....
Have anybody tried the latest firmware for October if the battery issue is solved?

Very few users complain about this, maybe because there are only a few of us or it is not an issue as very seldom users remove the battery?
As for me when the level goes between 20-30% which is usually on the 3rd day I recharge the battery.

Dude Battery callibration could help you .. same condition was wid me .. i callibrated n now my battery is MEGA now
1.Root ur fone
2.drain your battery to zero
3.short all your battery terminals to make sure your battery is totally dead..
4.then charge your battery to 100%
5.n press CALLIBRATE from ur callibration software.
i will like to tell you that some processes drain ur battery very rapidly ,, i removed some apps n processes and now battery lasts,
so i will advise u too flash ur fone completly takin ur data backedUp..

Whatever you do "DO NOT SHORT YOUR BATTERY TERMINALS UNDER ANY CIRCUMSTANCE" That's a fire hazard. Lithium Ion batteries can generate massive heat very quickly and have been known to explode on occasions.
Practise good battery management by charging your battery whenever possible and keep it on charge for as long as you can. This will condition it to give maximum performance.
Remember you can't get a battery to give any more power than it has from the charge you give it.
Calibration does nothing to the battery it only allows the software to monitor more accurately.
Lithium Ion batteries should never be allowed to discharge below a preset level as they will then die and will not charge again
lol im about to create a thread about this issue, i thought its only me who experienced this issue,, i've encounter this problem as well,, everytime the battery reach the 15% or the low battery warning, it drains very fast from 15 to 1% it just like about 2 minutes then my phone shuts off due to very low battery level
oh yea,, try the *#0228# it shows the real battery %. in my experience,, from 40% battery suddenly drop to 18%. btw for the calibration apps from the playstore, it just delete your batterystats.bin which have no benefit at all. anyone who encounter this problem please share your experience
I installed Battery Notifier and adjusted the low battery alarm at 25% . It is just a workaround but it serves the purpose.

okay our issue is NOT about BATTERY LIFE, but about BATTERY PERCENTAGE,, DUDE.
in this review the reviewer encounter the same issue like us
"A couple of times we experienced a sharp dip in battery life when the levels went below 20 percent"

Hardware or software I don't really know.
As I use the mega 5.8 as my daily phone I see to it that I dont go below 20%. And evry other day or a maximum of 3 days I always recharge my phone. Perhaps other users have a similar routine so very few if any, complain about the issue on this thread.

yea, i think thats why only few people who noticed this issue, they rarely use their phone below 20%. btw i just post a new thread in samsung developers forum, dont know where to report this issue so i post it there lol
i've try calibrating the battery, no differrnce at all. oh man , i wish samsung realized this issue
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:
Here is the original thread i created

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:

btw its charging now so ill give you a number when the battery drains completely
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? ?
