Hey Everyone,
I apologize if this is a repost. I know I read somewhere (I believe here) about a similar issue, but I couldn't find it in searching.
A little background - AT&T SGS2 running stock rom (2.3.4), rooted, using a custom kernel (2.6.35.6) I got off of here.
Anyway, my phone has been working great for months. All of a sudden, my battery indicator is completely wacky and innacurate. It seems to have started after I came back from a trip and had to put it in 'airplane mode' a few times.
The battery level indicator goes down very quickly, and is not a true indication of my phone's charge level. I noticed it a couple days ago (after we came back) where after about 6 hours, I was down to 40%. Normally after a full day's usage I am still at ~80% by the time I get home from work. Since my phone had been running for weeks without a reboot, I decided to reboot it, thinking maybe I had some overzealous background processes running. It came back online with the battery indicator at 8% (down from 40% a minute prior)! After about 30mins or so, it began to go up, and settled around 14%. It stayed at this level for hours, until I plugged it in when I went to bed.
The next morning, same thing, it would lose 1-2% every few minutes until it got down to <10%, where I would get a warning about a low battery level. But once it hit that mark, it would stay there for hours and my phone would work perfectly fine.
As I mentioend above, I thought I read a similar story where the recommendation was to turn the phone off, charge it up all the way, and then turn it back on after it was fully charged. I tried that last night, but my phone is down to 87% after only 2 hours of non-use.
I've made sure that UV/OC'ing was disabled, that no background apps are doing anything weird, etc. And it's not like my battery is really dying quickly - it's just that Android thinks it is. I've checked the level using multiple programs, and all report the same incorrect information.
Does anyone have any suggestions on how to fix it? Thanks!
You have encountered two separate issues, one of which is widely documented (fuel gauge reaction to rebooting), one of which is unexpected but possible on UCKH7 (abnormal drain).
But it doesn't look like the battery is really draining that much quicker, only that it's showing that it is. For example, while it might take me only 3 hours to go from 100%-10%, I'll stay at 10% for hours.
It's like the battery is no longer calibrated properly.
Do you use Samsung original charger? If not, try. It should go away.
Take your battery out for a few minutes. The SG2 differs in that it uses a chip for battery calibration/stats. You need to cut power to it completely to reset it. Now, if it still does it afterward, either the battery is faulty, or the phone's ability to measure voltages is wonky.
Also, are you using the phone's Power Saving mode? Maybe the battery is dying but the phone is taking steps to make it last longer?

I used to never use my Samsung charger and never had issues. However, months of using my blackberry charger has rendered it now ineffective. The charger dongle was slightly smaller, and its continuous wiggling messed up my phone's power port slightly. It's a good thing that my Samsung charger still works.
When we were on vacation, I was using my wife's charger for her phone (T-Mobile G2x) so we didn't need to take two (seemingly) identical chargers with us. My understanding was that the pinout and voltage were all the same, so I didn't think it would matter. Maybe that had an impact?
Normally I use my Samsung charger, and have been since we got back.
I haven't tried removing the battery yet, since its in a hard shell case and was hoping I could resolve the issue without taking it apart. But I'll try that tonight.
Power saving mode is disabled. I've also disabled BT, Wi-Fi, GPS, and shut down every app. In the time since my first post (84%) and now, I'm down to 58%, and my phone has been sitting on my desk unused the entire time.
According to the built in battery monitor, Android OS accounts for 92% of battery usage, with Display at 3%, Cell Standby at 3% and Phone Idle at 2%.
As I mentioned above, I thought I read something about a 'trick' to reset the battery gauge by turning the phone off, charging it to 100%, unplugging it, and then turning it back on. Was I mistaken?
Thanks for the responses.
FYI - I just pulled the battery, let it sit for a minute, and plugged it back in.
Battery level went from 58% to 39% after it powered back on.
I'll try charging it again to see if it has any noticeable impact.
Oh, I did want to mention that I've been very religious when it comes to charging my phone properly and trying to "take care" of the battery. I never let it get below 20% (outside of recently due to the issue), I always charge it up to 100%, I never do quick "let me just charge it for 15 minutes to make a call" type charges, I always use a wall charger and not a car charger, etc.
Down to 38% during the time it took me to type this...

That to me sounds like you might have an app creating a wakelock and preventing it from going into deep sleep.

With the exception of high load immediately following a reset (which is why it goes funky on a low-battery reboot), it's basically impossible for the fuel gauge to go out of calibration. It's designed to continuously converge towards truth.
Check the raw battery voltage when it seems to be funny. If your voltage is consistently low, you might be experiencing a hardware failure (like maybe the battery's protection circuit is on its way out.)
After pulling the battery, putting it back in and recharging it, it seems to be working well now. Too early to say for sure, but I went the entire afternoon and evening (up until now) with some mild usage, and am only at 84%. So far so good!

The phone has a voltage drop which causes the drop from 58 to 39 when you reboot it. I'm not a fan of it either.
My appologies if this question has been answered somewhere else, I could not find any other threads with a similar situation.
My phone was dropped and ever since then it has not shown me the right battery level. It will charge on USB or AC up to 99% and stop. I connected it to AC power 30 hours ago and it never gave me the green light. This is after a full drain and then recharge. It did however stop charging at some point. I noticed no light was on, red or green, turned on the phone and my battery had gone from 99% to 41% in 22 minutes. I plugged it into USB and it appears to be charging back up. My widget now shows 84% with 4334mV (i dont know if this is right or not).
It is not an issue with the battery. My wife has the same phone and I swapped batteries. Mine works fine in her phone and I have the same problem with hers.
My other issue is that when I use the phone off the charger it will not show me the level accurately when it is draining battery. Example being, I unplug the phone at 99%, within 5 minutes I'm down to 92% (i know this is not unusual because of how the batteries charge). But, I will stay at 92% for hours and hours, with moderate use of internet, phone, and apps. Then it will fall from 92 to 60 ish in a few minutes and do the same thing. Sometimes it will tell me that I'm getting low (under 15%) other times it just turns off a second or two after the notification. If I plug in the phone and turn it on it shows me 1% and charges up to 99%.
In the few minutes I have been typing my phone charged up to 91% with 4336mV.
I was running ViperRom ICS when the issue started. Restored it back to Stock with no root and the issue remained. Now I am running Mean Rom ICS with the same issues.
I have cleared the battery cache in recovery too.
Any help would be appreciated.
If you kiss it. your phone will love you and it'll be all better. NOW KISS IT AND TELL YOUR PHONE YOU'RE SORRY FOR DROPPING IT! LOL!
Based on my experience with batteries of all kinds, it sounds like one of the cells may be damaged. Best bet is to get a new battery. They are decently cheap for a good one. Im actually looking for an extended unit myself. If you come across one, please PM me.
Thanks
That was my first thought but when I swap my battery with my wife's battery I have the same problem. Both batteries work fine in her phone but not in mine.
Sorry to bring this up again, my bad. But seriously you are not the only one with this issue.. I had the same problem since stock, swap battery didn't help either.
Hey Guys and Gals
This morning my phone was completely drained so i plugged it into the wall plug to charge up. However it did not turn on and begin charging until i did a battery pull.
When it began charging, there was the little yellow triangle (normally there when my device has been drained). A couple of minutes after, the battery began charging BUT it was nearly full
So i switched on the device, went to Applications>Settings>About Phone>Status
There the battery read 96% and charging from AC. When i unplugged it, the numbers began literally jumping backwards and the phone died within two minutes.
I tried charging again and had to do a battery pull again. For good measure, i did a factory reset but the issue was there still, only, when it is plugged in, the battery slowly DECREASES :S maybe like 1% every 2 minutes.
Can someone please help me and let me know if it is a battery issue or a phone hardware issue itself?
Im running Gingerbread btw (downgraded from ICS about 3 weeks now because it sucked....and i missed GB lol)

Easiest way to check is to use another battery in your phone and/or to test your battery in another phone.
So you only need to find someone with a compatible phone/battery.
Or go to a store and ask for help.
Good luck !
Or use a volt meter to test if your battery is dead ie <3.7, the s 2 tends to exaggerate the value more often than shrink the percentage of battery, but your case is a bit extreme, it might have to do from going from ics to gb, don't take my word but apparently its bad to downgrade from ics to gb
Hello, I've started having some weird battery issues with my HTC One X+, wonder if anybody else has seen this before. I've attached a screenshot of the battery graph for my phone, so you can see what I've been encountering.
It all started two days ago, when my phone charged down and shut off, despite being idle and connected to my laptop for USB charging the whole time. Since then, I've been seeing all kinds of wacky behavior with the battery stats. The status has been stuck on "11M 19S ON BATTERY" for the last three days. It discharges really fast even when idle, which it wasn't doing before. Last night, the battery chart shows the phone either being awake or with the screen on, but it is wrong: the phone was turned off.
I turned it off almost all of today, turning it on maybe 2-3 times just to check the charge and then immediately turning it off, and connected it to AC charging the whole time, but the battery charge seems to go up and down during that period! At this point, my battery stats seem completely corrupted, except for the fact that the phone does shut itself off when the charge goes to zero, so the total charge may be correct.
I'm not sure if this is a software issue or hardware, as I seem to be getting strange data from the software. I looked at many of the battery threads in this forum: they say to charge the phone to green and discharge a couple times, but I cannot get it to go to green again, even with the phone turned off and AC charging! I should still be covered by the 1-year manufacturer warranty: do I need to send it in for repair or this is some known software issue that I can fix myself? I'm running stock unrooted Android 4.2.2 Sense 5 on the international unlocked HOX+.

I thought I'd update with the latest. After a couple days of freaky battery behavior, I was finally able to get the HOX+ fully charged again, after which the problems went away, still no idea what caused it in the first place. I wanted to make sure it really went away before posting: it hasn't recurred in the weeks since.
I fell asleep last night with a podcast playing on my HOX+ at the lowest volume setting and held next to my ear, woke up this morning with only 50% battery used after 12 hours of almost continuous mp3 playback. I've always been impressed with how little battery this device uses while playing mp3s, still going strong. :victory:
Sigh, spoke too soon, it's constantly discharging again, no rhyme or reason why, and the charger can't keep up. The weirdest part as always is that it can't even recharge while turned off, implying there's a short circuit or something else wrong with the hardware. I'll see if I can get it to charge eventually, may have to turn it over to HTC this time.
Hello, I was told to post my question here. I'll just copy/paste:
I have a Samsung Galaxy Beam (GT-i8530) and recently it started to show weird behavior when it comes to the battery level. It drops really fast and takes forever to charge up to 60% and then jumps to 100% in a minute. It also happens that when I leave it charging it says 100% but the moment I remove the cable it shows a lower percentage such as 38% or 56% (it happened again today, I left it charging for almost 3 hours and when I checked it said 100% but when I removed the cable it changed to 34% and the warning message appeared telling me the battery was under 50%). At first I consider it to be a problem in the battery but Galaxy Beam comes with two batteries and the problem kept the same even after I've used the second battery.
I've searched around but everywhere I look it gives those charge/discharge cycles guide and I've tried that already but it didn't work at all. For one no matter how long I keep the cellphone charging, even if it says 100%, if I restart the cellphone it will starts with 94% instead of 100%. Is there anything else I can do to fix this? Should I try the charge/discharge cycle again? Could rooting my cellphone and doing the cycle calibration again but with a rooted device and the calibration app for it help instead of doing the calibration for unrooted devices or it's unlikely that will make a difference. I don't know what else to do.
Thank you.
Edit: It got worse. The battery was at 45% so i put it to charge. When I came back it actually dropped down to 28%. I tried to restart the cellphone and after I did it started with only 15% instead. I've checked the cables, the chargers and the USB door, there's no problem with any of those. Tho recently sometimes when the cellphone is charging it starts vibrating non stopping and it's not the cables contact because it does not show any message saying the cable disconnected.
HELP!
