[Q] Extreme low battery usage / Battery drops/ SG2 suddenly shut down - Galaxy S II Q&A, Help & Troubleshooting

Hi all,
I've got my sg2 since june and since the first moment I have got the same problems. I had the stock ROM & kernel with android 2.3.3. The problems I experienced were these:
1) extreme low battery life (6-10 hours, with normal usage)
2) when using heavy apps, my s2 just suddenly turns of. When rebooting it, it has a battery drop of like ~15%. (this only occurs when battery is already bellow 40% left).
3) Like 5-20 times a day (it really difference day-to-day), I got the notification that I have to put my sg2 on a charger. - So the battery bar drops from example 80% to 1%. After like 1 or 2 minutes it just fills up back again to the 80% before. Sometimes when this occurs, it also turns in a few % (like 80% before, and afterwards 75%).
So what did I already tried to fix this?:
- bought new 1600mah battery > didnt solve the problem, conclusion: no hardware malfunction
- I thought the problems could be occured by the tiny space between the battery and the frame of the phone. So it had a lack in connection... So I filled up the little space with i tiny piece of paper> nope didnt helped.
- downloaded mutiply apps for battery saving, task killers, etc etc.> didnt help!
It's really really frustrating, and I'm guessing more and more it's just a software problem. I do have warranty/insurance on it, but i don't want to send my phone to a repairservice because then I've no phone for like 3 or 4 weeks.
So my last option for me was to try a custom ROM and Kernel. So last week I installed the Lite'ning ROM. I also followed up the advice to calibrate my battery, so i did.
And the first day it was running really smoothed! At the end of the day my battery was still alive and I've used it for over 20hours, so I was really statisfied... But a small sidenote: I had a really busy day at work, so I didnt use my phone that much.
So next day, used it alot more. After 5 hours it had only 50% left.... And that's not all, my phone turned off suddenly. Not once, not twice, but 5 times that day.
Seems all these solutions didnt help. The only positive thing of installing Lite'ning ROM is that i now have about 4 or 5 hours more battery life a day.. But if I use it alot, it shut downs a lot more. Wich lead in more battery drops after reboot.
I'm really desperate, and I really don't know what to do now. Does someone have got these really frustrating problems, and do you guys have got some solutions?
And one more question: is my warranty/issurance voided after installing the Lite'ning 6.1 ROM? or can it by tresspassed by using a Jig?
Tnx for your time, and I really really hope you guys can help me cause i'm really getting sick of all this. It's killing me!!!
ps. sorry for my bad english

your warranty is voided by installing custom rom but u can unroot and use the jig to remove counts in counter.
now apart from that it seems if u use your phone for 5-6 hours continuous it will drain the battery because main source of battery drain is the screen display but for moderate use it should be a little over a day.
i am unclear about your usage but still if you have doubts you should really get it checked at a service center.

I would flash back to stock, use the jig to clear the flash counter and exchange that phone, seems it has some type of hardware issue that could be related to temperature as it only shuts down when you use it.
My 0.02 cents

My usage is definetly not THAT extreme, i guess moderate: I never watch movies or youtube, just some messages with WhatsApp, about 4 of 5 times a day checking Facebook, same for Twitter, always GPS off, some time of the day Wi-fi on, never play games, always closing apps on background.
i've got an example of my battery usage (this is one of the best battery usage days i got!!!):

[Q] Any one else have this weird battery drain?

I got my galaxy s2 (international version) about 4 months ago. Recently I've noticed some weird battery drain mostly when I restart my phone, but it happens other times just out of the blue.
It might be a software bug not showing the proper battery level, but I've attached pictures that show normal battery drain even after that jump down. Obviously, if it was a a software fault the battery percentage should remain level or go up slightly. (Yes the battery level does go up a bit, but I lose significantly more battery than I gain.)
This has happened in many instances and I've only got a screenshot of two. Sometimes I get big discharge and at other times its small. It's pretty annoying when you think you've got enough battery and go out, only to find the phones dropped 20-30% out of nowhere.
My phone is unlocked and not branded (bought from carphone warehouse UK- CPW). It's running stock XXKI4 firmware (2.3.4) and I'm not rooted.
So my question is, has anyone else seen this happen or have I got a faulty battery? Is there a fix?
Hi there,
Battery drain is one one the main argouments you can find in this forums. ATM I'm in your same condition: after latets ROM ugrade (I've got latest CheckROM release), my phone "sucks" al lot more battery than before.
A lot of things could affect this: themes, skin, kernel, application bug, bad battery checking and so on. There isn't a valid answer... I think you must indagate on yourself, comparing what you find with forum's infos!!
Good luck!!

There are several threads about battery drain.
For example here => http://forum.xda-developers.com/showthread.php?p=16973603
Maybe you find a useful tip.
You have always test it on your phone under your conditions.
You can try to flash special (Custom) ROMs and kernels, which are optimized for better battery life, but as there are so many different influences on battery life, it is nearly impossible to find a general "fix" for all users and phones.
Good luck!
well at least yours lasts 15 hours, mine lasts at most 10 hours on heavy usage.
P.S. I am using 2.3.5
As to Anwser to those "drops" or "gaps" in the graph, just recently i noticed that my phone was working normally, i was monitoring its battery drain (i have a thread going on about it), and after some time of no using, after class, i noticed that my phone asks for my SIM PIN again, and is in Safe Mode (i dont really know what that it). When i checked the battery monitoring graph (battery info) i notice the absolutr same fall (from 70% to 40%), but i remember that i saw and used my phone at 60-50% too ! So i can only assume that the phone crashes, eighter reboots for some reason, and the data isnt saved (for example it saves the data every 2 hours or so), so there appears the "gap".
Thats simply my opinion, but i do remember using the phone at the % between the two extremes (IN the gap), so i guess the data wasnt saved.
EDIT: Ha! I'll add some pis now to show you guys this: so in my current history i have two gaps, one big, and one smaller before. So, the first time, i turned off the phone and PULLED OUT THE BATTERY aswell cause i wanted to check my batteries mAh (its 1650 but thats offtopic). Thats how the small gap appeared ! As for the big one, my phone seemed to crash and reboot while i didnt notice, because in an hour or so of no using i woke it up and it asked for the SIM PIN.
So there, i think the phone eighter crashes or doesnt manages to save the battery data, and those gaps ("falls") appear.

[Q] Battery Drain Problem

Hello all,
I purchased a Galaxy S2 at the end of July, I live in the US, so it was from Amazon. The phone has been phenomenal, an amazing piece of technology.
I rooted the phone and flashed Lite'ning Rom 6.1 XXKH3. Still worked great, with no problems at all.
However, starting about a week ago, I am getting an extremely fast battery drain. Since then, I have spent hours looking at threads trying to figure out what was going on. I updated the rom to UltraToxic Rom v8.0 XWKK5, still no change.
I used Titanium Backup to freeze many widgets and app processes, still no change. I am currently using better battery stats to monitor wake locks, however after managing the wake locks, still no change.
I then bought a replacement battery thinking that the battery may have been bad, sadly, there was no change.
I have been trying to find a solution to this and had tried many other suggestions in other threads to no avail. As of now I have come to the conclusion that the device might have some type of malfunction that is causing this.
Am I going crazy or am I missing something obvious? Any help would be greatly appreciated.
Thanks
I have also re-calibrated the battery, still no positive changes.
Seeing the battery graph, you have your screen on a lot of time. Screen sucks battery a lot, so there might be one of the causes of battery draing.
Also you seem to have all day enabled 3G/WiFi, that also sucks some battery with it.
You can try JuiceDefender and see if it can help you extend a little your battery.
change kernel
Try flashing hardcore's "SpeedMod Kernel" and you will never complain about your battery life.....
After flashing this kernel my worse battery life was 1day and 12h with 3.5h screen on and wifi 85% ON.

Lol.... It's obvious he has some kind of battery problem, he is not using the phone much, and galaxy S 2 should have at least 5-6 hours screen on time and the phone lasted 3 hours.

Since I had all data on the phone backed up, I did a factory reset. I also flashed the UltraToxic Rom v8.0 XWKK5 as well as the suggested SpeedMod Kernel. When the battery was at 100%, I calibrated the battery. I tried to leave the phone idle as much as possible, I did use the internet for about 10 minutes to check e-mail, news, etc. So now the phone is essentially "empty" in terms of apps downloaded, I got rid of all widgets on all home screens.
There was still no positive change, I do really like the SpeedMod Kernel though, I do notice faster responsiveness from the phone.
I am beginning to think that the problem may be the hardware and not the software or battery.
I've got similar problems here. I am suspecting a hardware problem (I damn well hope it isn't coz i got mine from hong kong) because my phone never goes into deep sleep mode for more than 50% while the screen is off. I've tried at least half a dozen different kernels and roms and nothing helps, this is even in airplane mode i.e. with pretty much everything turned off. I've tested wakelocks and dont get anything more than a couple of seconds. I had my battery charged to full at 6:30am this morning, went to work and got home and it was dead after just under 12 hours with being idle 75% of the time. This is worrying as most people's battery lasts at least a whole day.
So I know it can't be the kernel, I know it cant be wakelocks, I know it cant be wifi or 3g data or anything of that nature so the only thing it comes down to now is hardware...
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
SOLVED!
After days and days of trying to fix the issue of the phone not sleeping (and therefore draining excess battery whilst idling) I have finally fixed it!!!!!
First i noticed that along with the sleep problems, I was getting the problems with car mode popping up randomly, the phone going into mtp connection mode, and thinking its charging when it was unplugged. After looking into these issues (and i thought it was a longshot) I decided to do what people were saying and CLEAN THE MICRO USB PORT.
Now you're probably thinking I am a crazy man, but now im just crazy happy that I don't have to send my phone back to Hong Kong!
Instructions:
1. Get a clean, dry, soft-bristled toothbrush.
2. Take any case you have off the phone.
3. Gently insert the bristles into the port and "flick" it out softly.
4. Repeat this about 10-15 times
No matter what ROM, what kernel, what modem i tried flashing, my phone was always sitting on no more than 50% deep sleep mode when idle and had no wakelocks or "rogue apps".
I am now getting 90% - 98% DEEP SLEEP MODE!
I obviously can't guarantee that it will work for everyone, heck how it solved the issue is a mystery to me, one which probably an electronically-minded/computer systems person could answer. What I can say though is I searched high and low online for about a week. I tried different kernels, I tried different ROMs, I tried "re-calibrating" the battery, I used BBS to check for partial wakelocks. If you too have tried all this and have had no success please PLEASE try this and see if you have success!!
Thanks for reading!
....
Or if you didnt...
TL;DR: If you're having battery drain problems clean the micro USB port with a soft toothbrush.
The phone never sleeps when charging, the CPU idles at 200 MHz, whatever was in your USB port was probably making contact with the pins that tells the phone it is connected to a charger when it actually is not, so it was idling at 200 MHz and was not receiving power, that's the only explanation I could fathom
Do two things:
Install CPU spy and show us what the deep sleep percentages are,
and try disabling wifi. Also, what is the router?
I have a battery drain issue; but its kind of screwey as i will reboot my phone and lose about 20% of the phones charge. If i turn it off and leave it off for an hour the charge comes back. Its random as well; only happens once a week. I have had this problem on different roms. You might have a similar problem to me. Possible the hardware that detects battery state is knackered.

[Q] Ray battery recently shortened and it has also started time travelling

I've got a bit of a problem with my Xperia Ray and despite hours of googling I still can't find a solution so I thought I'd see if you guys could help
Had it for about 6 months now and it worked great up until a couple of weeks ago when suddenly the battery life got way shorter, like I used to be able to get close to 3 days if I didn't do anything but sending messages and using some basic apps and even with pretty heavy use it still lasted well over a day.
Recently though it lasts under 20 hours with absolutely no usage, when I leave the phone overnight it loses about 40% charge when previously the use was under 10 for the same time period and even if its turned off it loses charge at a similar rate.
The other problem that started around the same time was that whenever the phone turns off from lack of charge or I take out the battery the date resets to 6 January 1980 and the phone seems unable to automatically correct it. Previously my phone was able to retain the date even after the battery had run down completly.
The only thing I can think of that changed before the problems started was that I used a solar powered usb charger for a few days because I was tramping but I have no idea what that could have gone wrong or how I could fix it.
I've tried a full factory reset, upgraded the android software to 4.0.4 and used various battery apps to try to find anything that might be using all my battery with no success.
Its driving me crazy so any help would be great.
Also here's a picture of a recent day of usage (not enough posts to embed it properly sorry), except for a short run I didn't use the phone for anything

Could be a lot of things. If the solar powered charger made your phone really hot while charging then the battery might be permanently damaged and you should try a different battery. It could also be that your power meter has gone wonky and this can be reset by charging the phone to 100% and then removing the battery and the usb cable from the phone for 10 minutes. Return the battery to the phone and charge it back up to 100%. Usually, when I experience something like this, it is some app that is draining the battery. Since you have just been trekking, maybe it is google maps. If it is tracking/updating you location, it will drain your battery really fast. You should be able to see this, just by going to system settings->battery. Stand by or Display are usually the big battery hogs.

I don't know anyone with a ray battery but I can buy a new one relatively cheap so I'll do that and see how it goes
I'll post results in a few days
Well I got a new battery yesterday as suggested and tried it out from full charge but unfortunately there was no change in the battery life, it still ran all the way down in less than 20 hours with minimal use
Begining to wonder if its a hardware fault within the phone itself

Moto E Xt1527 discharging quickly

Hey guys! I want some advice to check if this problem is normal or maybe its a manufacturer defect.
Anyway, I bought this phone about 5 days ago, and in the time I've been using it, my battery lasts about 7 or 6 hours (also it takes like 5 hours to fully charge it, which makes it worse). I thought it was because the stock ROM isn't very optimized, but later I started using cm 12.1 and it seems to last almost the same. Also, I started using an app called "current widget" that checks continuosly some info like the mA that is using at the moment, and I found that when I use it, it's mA is between 500 and 600, and sometimes it's like 180. Is this normal?
I'm worried because I've read in reviews that the battery of this phone lasts about a day and half and mine barely lasts 7 hours. Please, help...
Mine will last for 2-3 days if left alone. I'd download an app or CPU monitor to see what's running and draining the battery.
I repaired it already ^^ I just flashed official firmware again and no more battery draining and heating.
Battery draining could be many things but usually comes down to rogue processes.
Since android is java based over C, it becomes a garbage collector. Be sure to clean your device frequently to avoid internal confusion.
If a simple cleanup doesn't work, you can try to remove processes from loading at boot.
I honestly think that a reflash of your ROM is a bit extreme for a battery draining problem. I would try to exhaust every other avenue first.
I know, but I even tried disabling apps and it stayed like that. Also I flashed other roms and the problem didn't stop. I was going to claim my warranty and that's why I flashed everything again and somehow that solved it. I suppose my carrier modified the software somehow and that's why my phone had that problem.
Put your phone in airplane mode when you aren't using it. See if the battery drain persists. How is your signal? If your phone has a low signal, it will actually boost its radiation to try and keep the signal or establish a stronger one. This only is a battery killer and an issue that cannot be fixed by any software/firmware update that I've ever heard of.
If what I suggest seems to be true, airplane mode will be your friend. Or at least turn off data while not using it.
Good luck!

Extreme Battery Drain after OneUI 2.1 / September Security update

Hello all, it's been a while since I've posted but this is quite a serious issue and could some guidance. A few weeks ago, I finally updated my Galaxy S9+ to Android 10 after being on 8.0 for so long and it's been a decent update so far. I had gripes with SoT not being the greatest but it was tolerable. Last night, I received an update for my phone and I installed it. Didn't think too much of it and continued on. I charged from my phone to ~87% today, used it lightly while working. By the end of my shift, I had 50% left.
I left the house to go for a 81 minute walk with 47%. I usually don't worry about having enough juice to make it back home but I experienced the worst battery drain I've had with this device so far. During my 90 min walk I:
listened to Spotify using my Galaxy Buds (one ended up dying towards the end because I forgot to charge them)
Checked Instagram occasionally and responded to some texts
Took 2 pics in Snapchat
Had a short video call on Messenger
It was right after the video call I noticed my battery was at 17%, which I thought was very strange. I don't leave apps running in the background for long and I have a habit of closing them out when not actively using them and I noticed the battery kept on draining despite there being no apps open besides Spotify.
Turned on the medium power saving and within a few minutes, I was at 5%. Decided to kill everything and pit my device on max power saving mode for the first time since I've owned the device. By the time I was home, my phone was at 1%.
I'm really baffled at how the battery drained at an exponential rate. I'm a medium user and I've had this phone since late 2018. Never leave location services on, never used AOD, and used the FHD display instead of QHD along with dark mode.
I'm hoping today was just an outlier as I want to keep this phone for another 2 years, but if this happens on a consistent basis I'm gonna have to start searching for a new device.
In the meantime, I have charged my phone to a 100% and disconnected the phone and observed the following:
Within 2 minutes of disconnecting, battery went from 100 - 98%. Not a good sign considering it was just idling
The battery continue to drain every other minute and I could see the battery go down on each unlock
Wiped the cache partition and I went from 93 to 94% for a brief moment prior to the phone going back to the same pattern
This is very worrisome to me as I don't believe the phone will last until midnight, I'm wondering if it's possible to roll back to the previous update.
TL;DR - After the update yesterday, the battery drained at an exponential rate despite light to medium usage
Also, here's some screenshots of my battery usage

I know this isn't the answer you are looking for, but all I can do is suggest changing the battery and doing a full, stock firmware flash via Odin to completely wipe your phone.
I recently replaced my phone's battery and did flash the firmware and my battery is really hanging in there. My battery was also 2 years old and before, I would get about 3h SOT when I play a game (and I do a lot). Now, I'm getting 5h SOT no problem with about 2-3h gaming included, so I really do suggest a battery change. I'm thinking you could be able to squeeze another 1 or 2 years into this amazing phone.
