[Q] Battery indicator extremely inaccurate - Captivate Q&A, Help & Troubleshooting

Hey guys,
Just drained my battery. Charged it for 20 minutes to 15%. Rebooted phone. Battery is now at 51%.
This happens regularly on the two captivates i've had. what's going on?

bump...come on folks i cant be the only one with this problem

I had that issue yesterday. Just reboot the phone and it will show correctly again.

I've noticed similar batter issues as well. I suspect the problem is on Sammies end though. Often I will notice the battery at 75-50% but if I go into settings -> status -> battery, I will get a much lower %.
Hopefully the issue will be resolved when they decide to release froyo to us.

[Q] drastic battery drain galaxy s

After a difficult update with Kies I was able to upgrade to Gingerbread.
Everything seemed to go well the first time then I found drain battery and slowing down on the system.
So I decided to make a simple wipe which reported the phone as fast as at first, but the battery still has problems.
In one night from 90% it was completely drained so today I decided to use 'Battery Calibration' made from user 'marosige'. This time in 5 hours I lost 30% of battery life using some sms, internet for 15 minutes, and playing cut the rope for 10 minutes. More or less.
However I have to see if the battery loses all of a sudden like last night which is the biggest problem.
All of this is not normal have you any advice?
Thanks in advance
Hi Fattox,
Dont worry your socks off I flash Roms quite often and this requires me to calibrate the battery. Sometimes with certain Roms I find the battery may drain quickly the first time and then things get better.
You say you have calibrated so that means the app you used should have deleted the old battery stats from your systems file. In saying that if you follow these next few step you should be ok (unless there are other issues causing the drain)
1. Make your you drain the battery fully until phone dies and can't be turned on by pressing the power button then....
2. Plug in phone and keep it off until battery is fully charged. Don't take it off charge as soon as it says full. Just let it go for about an hour more or so to ensure it's at capacity.
3. Turn phone on and use as normal until dead...
Providing there are no other issues causing the battery drain you should find your battery usage to be satisfactory. Remember to turn off wifi and gps when your not using them as well as maybe turning your screen brightness down. Anything that uses less power the better....
Hope this helps.
between the recalibration with the app and your point 1, I had the same problem: during the night the battery loose all the energy.. so strange.
All this after I upgraded to Gingerbread.
I'm going to test all this week then I'll spend my warranty.

[Q] Fluctuating battery charge

My battery charge fluctuates, sometimes it goes up from 5% to 35%, sometimes it seems depleted (2%) and if I check in 15 minutes it's 10% and so on.
I'm running CM 7.2 and previously Darky ROM 10.2. Since this started happening I've used a couple of the top-rated battery calibration tools, but to no avail.
Any ideas? Is it a hardware problem? Or a driver problem with the custom ROMs? Or something else?
Try the following If you haven't already.
Charge phone until it says it's full.
Discharge until it turns off. Try to turn it on to make sure it's absolutely flat.
Do this again.
Then charge it periodically so that you keep the percentage between the 20 and 90 approximately, and see if it improves.
Repeat first steps.
Wiping battery stats and similar "calibration" has no effect on neither the percentage shown or battery performance.

Thanks for the advice, I'll try it and see what happens. Any ideas to the cause of all this? Also, would buying a new battery help?
I don't really know the reason why this is happening, Li ion batteries can be somewhat of a black arts.
A new one should fix it anyway, and they're very cheap where I live at least

I passed through Same problem when i had updated my mobile to jelly bean for first time. But after 7-8 days fluctuates is decreased from +/-20% to +/- 2%. And fluctuates are gone after 20 days.
So dont worry, just wait for 20 days.
I have a Galaxy Nexus, not rooted, and it does this all day. 80%, 14%, 78%. All in a matter of minutes.
I'm discharging fully then doing a full charge to see if it changes anything.
My Sensation never did this and the apps I have are the same. In fact I've installed less on the Nexus...
same problem
i also have this same problem, check this thread...

[Q] Phone switches off even though it showed 40% battery

Have a peculiar problem, The phone drains off faster than usual for last few days. In couple of instances it showed 40% battery and suddenly the phone got switched off. When i switch on it showed 0% battery and again got switched off. When i put on charger it was back to 40%.
Also full charged battery drained to 25% in 5 hours, earlier it used to come atleast a day. Battery also looking a bit fatty in its surface. Any pointers if this is the battery problem or any calibration issues? I use the stock kernel - 2.3.6 and this is there since few months. The problem started only few days back.
This happened to me too and it turned out it's a battery problem.
When I changed my battery, everything went back to normal.
If you know somebody who owns a similar battery, you can test it on your phone.

[Q] Ativ S - battery draining quickly

Hello,
I have an Ativ S and about a week ago the battery started to drain very quickly - about 15 to 20 per cent an hour.
I do not have wifi, bluetooth or gps on and usually the battery lasted 2 -3 days but now I need to recharge twice a day.
I thought that this was maybe caused by a program so I reset my phone and reinstalled only a few programs, but that did not work.
1) Is there any way that I can see if an app is draining my battery quickly?
2) Could this be a hardware problem? If so, how can i tell if it is the battery or the phone? I think that my warranty has expired, so returning it is not an option.
PS It is on GDR2, no interop unlock or any other tweak whatsoever.
Thanks
I'm not going to say it's flat-out impossible for an app to drain your battery that fast in the background, but it's not far off. If you want to be really sure, though, enable Battery Saver mode immediately after unplugging the phone (at full charge) and don't use it. Battery Saver prevents all background app activity, so there won't be any apps running and therefore they *cannot* be affecting the battery.
I'm pretty sure that, given the rate of drain and the fact that it persisted through a hard reset, you have a hardware problem. The good news is that it might just be a bad battery - that is a thing which happens, and it's even fairly common on batteries a couple years old - in which case it's a good thing you have a phone with a user-replaceable battery! The way I'd test that is to swap your battery into somebody else's ATIV S and see if the problem persists. If so, it's the battery; if not, it's your phone. Alternatively, you could just buy a second battery and see if that helps.
One other thing to check: if the battery really is still working and the phone is draining it that fast, it'll be dissipating a lot of energy as heat. Does the phone stay abnormally warm while the battery drains like that? That would be a sign of a problem with the phone or the OS, as opposed to the battery itself.
Oh, and I'm pretty sure there are some battery diagnostics and charging statistics located in the Diagnosis app (##634# in the dialer). I forget the code for them but I have all of the codes written somewhere; alternatively, you could do some searching. You could compare the reported battery capacity there with the expected (design) capacity.
I reset my phone again, installed only Viber and till so far, the battery drain seems to have disappeared (or at least improved).
Some users on wpcentral reported that they had major issues with battery drain caused by Whatsapp.
I used Whatsapp for quite some time but never had any problems( till now).
Maybe the last update caused this, i dunno...
Anyway, thanks for your answer.
I will see how it goes and I will let you know.

[Q] battery drain, random reboot and other issues

Hi,
I got my (used) note 1 about a year and a half ago. I've installed alliance rom from the get go and experienced some battery drain. At first I thought maybe it's the battery, so I got a new one. This also didn't help but as the drain wasn't significant (I wasn't even 100% sure it really was a problam), I just continued using the device. After about a year the drain got worse (wasn't a battery issue, as I checked with an almost un-used battery). I figured changing a rom might help, so I moved to CM11, after installing an official version and re-rooting the phone. It made no difference, but I continued using the phone anyway. The battery drain got worse and today it drained 80% in 7 hours with almost no use (talk for about 5 min. and maybe 30 min. screen time with wi-fi on but no GPS). Also, the phone started heating a lot (it got to a point where it was uncomfortable touching the top of the screen due to heat. But it didn't shut down). Then the phone started rebooting itself or just freezing until I had to do a hard reset about once a day. I think it's only when it's in use but can't be sure. another issue is that when I try to take more than 2-3 pictures with flash on, the phone reboots (flash off - no problem). The heating was solved by underclocking the device, but the other issues persist.
I thought about changing ROMs again, but as it didn't help last time, I decided to ask for advice here first.
Any thoughts?
Taking pictures on low battery or bad battery with flash can cause the phone to power off. It could be either.
Install wake lock detector from the app store and check what's draining your battery.. Then either paste a screen shot to get more help.
Thanks, I'll do that.
But just to clarify, the phone shuts down (abruptly) when using flash event if the battery is charged. Also, there's no such issue when using the led as a flashlight.
OK, the drain in the last few days was due to a game I installed and forgot to greenify, so let's put the battery drain aside for the meanwhile.
Question is, what can cause rebooting?
