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.

I've read and read, searched and searched this forum and have not come across my exact problem yet...
I know there have been overheating issues, and I know there have been boot looping problems... all causing terrible battery life, mine has neither. Let me rephrase, my overheating issue is not due to me actually using the phone... On idle (with the screen off), my Rezound only lasts about 2 hours on a full battery. Granted, I live in an area where there isn't full service, but there is some service. I can watch as data is being exchanged with no apps running. What the hell is using data? I have a feeling this is what is killing my battery, the phone is not at all sleeping. I have deselected "always on data" and I turned off fast boot and auto sync.
Any suggestions would be greatly appreciated.
BTW, my phone is a bone stock refurb.
Try a factory reset maybe?
I can do that, but it doesn't really solve the problem. It just started doing this yesterday. I've had it over 2 months and haven't downloaded anything different. I would really rather just figure out what is causing it, so I don't have to do a factory reset every time something like this happens. You know? Thanks for your suggestion, I'm afraid that is going to be my last resort right before exchanging it...
Try exchanging the battery first. Start small. Work your way up to the big stuff(exchanging the phone). Why give up the customizations you've done if you just have a bad battery?
I was thinking it may be a bad battery, but it concerns me that I can watch the data stay running even though I'm not using anything that requires it. My brother has a Rezound and I placed mine next to his and literally watched the battery life deplete 10% in 5 minutes while his lost no percentage at all, both were idle with the same screen settings. Is it common for a battery to fail that drastically out of nowhere?

If data is constantly being used, something HAS to be using your data. I'd get an app like better battery stats and CPU spy. CPU will show you if your phone is going into sleep mode at all and better battery stats can show you which apps may be causing it.
Do you have the 4G antenna on?
I have betterbatterystats, it shows android system at the top of processes. That program is a little difficult to understand since everything is abbreviated.
I appreciate all of your responses. I just got off the phone with Verizon, they're sending me another phone AND battery for good measure. During lunch today I watched the percentage of my battery deplete while it was plugged into the wall and not being used, used a different charger, nothing. It wasn't even hot. I turned the phone off to try to get it to charge. when I turned it back on, it got to the lockscreen and then restarted itself. Boot looping now. I'm not going to fool with it anymore. Maybe the third Rezound will be better.

I haven't changed anything from out of the box other than visual properties. I'm assuming the network has a little to do with it, but it started failing way too fast to be a radio problem IMO.
I received my 2nd Rezound last week. First one had the hiss/feedback/interference issue through the headphone jack that escalated to a level of to not being able to use the headphones at all without being painful. Anyway, the new one is running very hot (battery) and is draining the battery almost as fast as you're describing yours to do. I've used both the standard battery and extended. This morning while using it at home on wifi with most of my syncs either disabled or set at a min of 2 hrs it drained my extended battery by 20% in 20 mins. I wasn't even using the internet or streaming any music or video. I was working on setting up calender and task list widgets. Phone is stock, not rooted. I will be calling Verizon tonight to see about getting a 3rd one. Sucks as I really like this phone when it's working properly. If the 3rd one has issues to and HTC isn't rolling out any fixes for them I might have to look at something else. But I don't want to!
I feel like if I can get the hardware to cooperate with me, I can get the software to. I was planning on rooting after the ICS push, but the phone obviously had different plans.
Set your phone to CDMA only, especially if you don't live in an area with LTE coverage. You will see significant battery advantages from that alone.

I should have mentioned that I'd already done that (only 3G here anyway). I've done all the battery management tricks I've read about but this phone has an issue. I'm not even getting half the battery life out of it that I was on the 1st one. And the battery gets significantly hotter then the other phone.
tried wiping battery stats after 100% and drained/recharged a few times?

I got this phone Friday.
I didn't root it Saturday but it was in the back of my head. Before I rooted it, I noticed that the battery life was the worst I had ever seen. I read online that this is a bug in 2.3.6 (good job samsung).
It charged while I was watching some TV, so I rooted it and installed UnNamed. This knocked me down to about 50%. I finished off the battery playing games. Then charged it back to 100%. When it was roughly 58% it froze so I had to pull the battery. When I turned it back on, and the battery was magically at 29%. Which seemed odd to me, is it just inaccurate or how does that work?
The hell is wrong with this phone? Nothing gets to me more than bad battery life. If I can't get this resolved, i'll have to bring it back to AT&T and swap it out for something else.
no advice for you, but mine is going on ebay when the htc ics phone comes. I haven't tried them yet. oh, I'm importing all phones from now on, too.
I noticed the same thing with my samsung get the galaxy nexus has a great battery...

Most more than likely it's the wiring leading up to RAM processor, and, consequently, the flux capacitor, which is probably where your problem is. The flux capacitor is what regulates the battery input/output which can sometimes lead to poor battery life, disappearing battery percentages, and in certain cases where your last name is McFly - time travel.

Search is your friend, this is a well documented situation. In short it's how li tech batteries work in combination with how our fuel gauge works. (it goes off of voltage vs counting mah, and there's voltage sag under high current draw, this equates to it showing lower than it is on reboots at low power)
Battery percentage artificially reports low when the device is rebooted on low battery. This is widely documented on these forums.
If you're returning the phone because of this one small minor glitch, good riddens.
Also, Unnamed 2.x is not immune to the BT-AMP bug that kills battery on UCKK6, since it's based off of UCKK6. This is why many reverted to Unnamed 1.x
And why did you post a new thread on this? There's a dedicated thread for UCKK6 battery issues.
You need to be patient dude. Use search and read through all the related posts in this forum. You can begin with flashing the rooted stock 2.3.4 with KH7.

It's a minor hardware glitch that happens only when you reboot your phone on low battery. Solution is:
1) Accept the weirdness of your battery rising after the glitch
2) Reboot when on charger if the battery is below 50-60%
3) Reboot at a higher level of battery
You didn't magically "lose" 30%+ of battery - that's impossible. You just had the estimate of charge level thrown way off.
As an example of what is possible - right now my typical drain is well below 1%/hour when the phone is sitting in good signal. In weak signal it's about 1%/hour.
Man I don't know what the deal is I'm on this thing gaming web surfing and other **** and I got my wife saying "Your always on your damn phone " and I get 18-20 hours per charge

Is that a problem of battery hardware or the phone? IS this a common problem with all i777? because I havent seen lots of people complaining about this?

It is, as I've said before, the one corner case where our fuel gauge fails. It's the small price we pay for NEVER having to worry about battery recalibration - it will always converge towards truth, the only problem being that high load after a reset (rebooting on low battery) will throw it off for a few hours.
I used to have a SM-9005 In Pink on TMO, however my dog decided it would be a good thing to pee on (thus causing acidic corrosion). The phone had the 10K MAH Battery from Zerolemon,
The N9005 itself worked, and did not...its mainboard became corroded where the display connector is and went all matrixy. The battery has 1 corroded strip, one is half corroded, and the rest are fine. I inserted it into the 900P, and it works fine. However battery drain seems to be much...faster...and phone turned off three times by itself. When I turned it on however the battery % went...UP!
Is there an app that will allow me to see how much MAH is still working in the battery? I would imagine there are dead portions & I am pretty sure NFC is not usable anymore.
After flashing a rom away from stock turning off seems to not be an issue and all I know is its been running 3943mv...

I have the feeling that you're playing with fire here.
Using a corroded battery is never a good idea. You have already said that the contacts are corroded and you've seen degraded battery performance and, quite frankly, erratic behavior from the battery.
Continuing to use this battery because it still technically "works" would be, in my opinion, irresponsible. Best-case the battery continues to degrade over time (as all batteries do). Worst-case would be a fried phone and/or property damage.
In my opinion, risking the life of a $600 smartphone isn't worth it for a battery that you can buy for $15 on Amazon.

Yeah,
It just started to randomly turn phone off even on normal rom so I switched it back out for stock battery.
Hi, got the C5 ultra a couple of days back. I feel that my phone slows down and lags when the battery is low? Its almost unusable due to the lag in the app drawer and recents panel. Im not sure if this happens everytime the phone is low on battery. Is this is problem for u as well and is there any fix?
Thanks

yes. it happens to me too.. also my battery takes forever to charge.. 15 mins = 2 % . but when it is turned off, it seems like any other phone.. contacted sony and all they said was to try the software repair, which i am tempted to do.. my youtube causes the whole phone to crash too every now and then. Have you encountered the same?

It does charge slow. I guess it charged from 14 to 78% in about 2.5 hours. My lg g flex charge in like 2 or 2.5 hours max and it had a 3500 mah battery. If we use a high amphere charger, it might mess with the phone's battery life. Other than the lag on low battery, I haven't had much issues aside from when the phone crashed 2 or 3 times when watching an hd video and then I had to manually switch it off and turn it back on.

Just did the sony repair as advised from sony support. The battery seems to be charging faster but my lg g4 still chargers faster as well. Hopefully some kinks were fixed as well, though i reserve my optimism since the software is basically the same.

After repairing, does your phone still slow down when the battery is low or has that been fixed as well? And did the repair delete all your phone's data?

Hi, used my phone for 2 days without charged. I decided to turn it off while charging since i noticed it was still faster to 100%. With regards to performance, I did not notice any considerable lag or heating, though the camera still had some lag and stuttering. The repair is basically a wipe of everything and reinstall. Sony said it was different to a factory reset as it like a "clean" wipe. Not sure what they meant there but so far im happier with the phone now. Still hoping that Sony releases a new update to address the slight stuttering, unsatisfying battery charging speeds and the laggy camera interface.
