I've noticed in my Battery Use that it shows the camera as using 70%, but I haven't even used the camera. It seems like I'm not getting very good battery life so I'm wondering if this is draining it really bad. Anyone else have this issue?

That battery use % thing isn't very accurate, and even when it is, it's hard to understand what it's telling you.
What do you mean by "good battery life" and what ROM are you running on your g-tab?

Is it normal to immediately get to the 99% of your battery just after you have the notification your battery is fully charged? Well not immediately, like in a minute, more or less.
And how long does your battery last? Video-wise, it lasts great, but even with low-end games seems to be such a drain even on the lowest brightness setting.
mine also
I don't know if it is normal or not, but mine does this also. Mine immediately goes to 99 percent after being unplugged.
Don't think it's a problem. Remember, you're relying on a sensor in the tabby to give you a percentage; who knows how accurate it is? I'd be much more concerned if the battery was being expended too fast after normal use.
Face it, some battery sensors are just lazy dicks.

And remember, talking dogs are liars.
I think is philosophically right. Any little thing you use is not 100‰ anymore.
But as that guy before me said, there is the sensor issue and on top of that the variables that my affect the very way the battery work.

i would say totally normal.
I would say the more important question is, How long does your battery last overall?, and not just from 100% to 99%.
At 17% I managed to watch America's Got Talent which was 1:25:++ on Auto Brightness in a dark room. As I said video-wise, the battery is great. But using it even on just simple document opening, the 90 - 100% mark seems to drain off pretty quick?
Can anyone tell me your battery stats? Even for a specific game with your settings(wifi on, auto brightness or lowest brightness, etc.). How long can you really go with this tablet on a pure gaming use? I really want to know. My old Android phone was not a battery beast or something so I understand, but this has quite the battery so I just want to make sure. Thanks.
Edit: Played Stardom for 3 hours at minimal brightness(like 5%). Everything is turned off(wifi, bluetooth, gps and etc.) took about 30% of battery. Seems legit. And by the way I have the 6200 so I have a network coverage. Anyone can compare with theirs?
i have a battery issues. it drains fast. is anybody know how can i fix my battery? is there any software than i use for improving battery performance?

More details please. What device is it, how old is it, when was the problem appears, and what rom are you using etc...
Software usually drains battery a little more quickly if not being used properly (when and how to use it).
So I've been having some weird battery drain the past couple of weeks. I have been trying to watch it and try to find the source of it but cannot seem to nail it down. I dont get that spectacular of battery life overall. First off, I am running zeus v6 with kl2 modem and nothing else done and no overclocking. Battery drain seems high overall, but above 50% battery its not too bad, however once it gets below about 50% battery the drain noticeably increases. Today for example, I unplugged my phone at about 8am, light usage pretty much all day, at 4 or 430pm it was about 50%, I get out of class at 7pm and the battery is down to 20%. Only thing I noticed was that I turned wifi on and left it on but it was connected to a network the whole time so its not like it was searching for a network. I had only about an hour of screen time, maybe a bit more. Its like this every day no matter what I do. I rarely get over 12hrs of battery life. I even got a new oem battery 3 or 4 weeks ago to see if that help but it hasnt much. I'm starting to wonder if it might be related to my phone that I just dont get as good of battery life? Not sure what to think, Im going to try flashing another GB rom in the next couple of days to see if that changes anything. I will post some screenshots of my battery life later tonight for you guys to look at. Let me know if there is anything else you want to know. Anyone else experiencing weird drain like this?

I had tried the two most recent versions of Zeus, and had unbelievably high battery drain. No WiFi or GPS use at all. If I was actively using the phone, my battery power would drop at roughly 1% every minute or two. And that's with screen brightness turned all the way down. Even with the screen off, it was pretty bad. I'd lose something like 7% an hour, with the phone sitting unused. I had basically the same results with Saurom. I pretty much just chalked it up to something within the ROMs themselves. I get great battery life with stock GB, CM7.2, and Paranoid Android JB.
I was reading that thread you posted qkster and it didn't really seem to be having the same issues as were in that thread. It's more just like no matter what I do the battery drains normally above 50% but below that it drains way faster even with less usage and not doing anything different.

My posts in that thread contained more links to other bigger threads and user experiences.
I was not offering a solution but only the means to one, if you are looking...
Alright, I'll look a bit deeper into that thread then and see what else I can find in there.

CM10 battery life is pretty poor, anyone found a solution? I remember on defy someone improved by using stock battd folder in place of the original one, however desire s doesn't have this folder. Undervolted, full charge cycle, disabled auto brightness light to moderate use and only 8 hours. Display is main culprit according to system, maybe its getting too much voltage or something? I'm no dev its just a thought

Perhaps you should calibrate your battery with an app like battery calibration
"It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break."
Make it twice or three time then you should see a difference.

Battery stats is a myth: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
The difference seen is purely down to the full charge cycles done in this method, after about 5 days the battery stabilized anyway, thanks anyway

I have the same issue on Pacman (CM 10).
My - I hope temporary - solution is to disable 3G as much as I can. For everyday usage, 2G (Edge) is sufficient for me. At home I am on wifi anyway, so I perform the heavy tasks then.
I noticed a very big difference when using 2G only vs. mode "3G preferred". It seems that there is a 3G battery draining issue with CM.
3g is known to drain battery. Keep it at 2g for better battery life.

I know this trick from the defy forums, cm10 had the same issue on that phone, I'm getting the best battery life with cm10.1 build 12 with andromod kernel, using ondemandx governer gives normal -ish life even with 3g enabled

Hello, I'm currently running cm 9, however the battery life is just awful
When the phone is on sleep it loses like 1 percent every 5-10 minutes
I am using an extended battery as well, please tell me what to do I was on GB before and the battery was outstanding, I could go on one charge the whole day with heavy usage, now i dont think I can make it through the day with light usage on this
thank you
EDIT: This could be a sleep problem, because when the device is on, the battery is normal
If you flashed the Feb 27 cm9 you should flash proton kernel so you can watch videos. Battery life isn't as good as gb no matter what you do. Also give it some time to settle in. It takes more than a couple hours.
alright thank you... I just flashed the newest version of cm9 a few hours ago, I was flashing a bunch of roms and this one seemed the best... do you know how to force a device into deep sleep cause that seems to be the problem i believe
OK I was just on 20 percent, then i rebooted my phone, and now im on 2 percent... im seriously considering going back to gb
Sounds more like a battery thing? With CM9.? + Proton I'm getting at least a day* with light use. Maybe a bad app or combo of apps? What does BBS say is eating the charge?
* - I say at least a day because I can't not use it for that long.

just the screen and the android system... very interesting thing though is happening
I'm running a bunch of quadrants to get the battery down to 0, and the battery is all the way down to 1%, however it's been on 1% for like 6 quadrant tests... maybe its just a problem with the indicator, however another indicator also says it's at 1%... very interesting
If you are on CM9, I suggest you flash Hefe or Proton.
I use Hefe because according to the posts being made it puts your phone into deep sleep, which means longer battery life.

Definitely a battery problem. This happens to me on one of my batteries but not on another. Time to buy a new one. I haven't tested it fully but it does appear to be just a display issue. Sometimes the bad battery will make the phone display 1% but it will still act as if it had way more than 1% charge left. I haven't done any testing on that regard but that's what it appears to do.

I don't believe it to be a battery problem, because I've been on GB with absolutely no problems and exceptional battery... I just upgraded to ics not long ago, and the battery life instantly screwed up
Have you set the cpu governor to anything silly like performance?
Have you let it charge up fully at least once?
Search xda for "better battery stats" app, use it to see if you're getting deep sleep.
Flash hefe over release 8 and youll have a little better battery. Proton doesnt deep sleep
Sent from my SGH-T959V using Tapatalk 2
Proton DOES deep sleep. That was one of its major features.
Certain scheduler/governor combinations work better on different kernels, though. If the specific one you like most sleeps better on Hefe, great. If the one you like does best on Proton, great. Just be aware that most issues are either physical or user-inflicted...
In this case, your battery is almost certainly dying. The variance in power over a reboot is a definite tell that your battery is probably swollen. If you can spin it on a table, the cells are starting to die. This does not mean you can't keep using it, but it does mean that your battery life will be irregular. It also means that you'll have significantly "higher" battery levels if you reboot the phone with external power connected, but the battery will discharge very quickly if it hasn't actually reached whatever level it believes it should be at.
