Does anyone else lose like 3-5%of battery life when they reboot their tablet?

Yes. And every android device I've ever had did it.

Well, I'm gonna have to disagree with the others on this one. I started at 64% battery, rebooted - still 64%. To ensure this wasn't just a fluke, I tried it a few more times, and tried it the next day after charging all the way, draining it a bit, and then rebooting. Doesn't sounds like it's anything to worry about though, just thought I'd add my experience.

Let the battery drain out until it's empty, then charge to 100% with tablet off. After full charge, turn it on and let it charge additional 30 minutes-1 hour, then unplug and reboot and see if this fixes drain issue!

I have a weird issue with my battery ..my phone will charge up to 100% but as soon as I unplug it...it takes less than 10 minutes for it to go down to 85%. Then it seems that the battery starts working normally after that...my phone is not rooted.
Any ideas or solutions?
Thanks in advance..

If you want help I suggest you provide more information. ie what rom you are running, how long you've had the phone, etc. If it is a brand new phone your battery may just need to be conditioned. Charge it to full, use it to empty, charge to full again and you should be good to go.

Its odd that a new stock phone doesn't run the battery well. in any case, the battery may not be calibrated yet. you can run this program. it will set the calibrate your battery for you. Let your phone drain down to under 15% before you recharge again. And let it fully recharge to 100%, then run it down thru the day to under 15%. After a few cycles like this, the battery will normalize. Then you will get a better idea of the battery life of your phone.

Hey guys I'm getting some really slow battery charge over here. I've had my phone plugged in the OEM ac charger for over 3h now and it went from 5% to 50% and the phone is getting hot also. I haven't touched it at all for those 3h and data is off so no internet. I don't get it. It's usually fairly quick maybe 1 to 100 for about 2h.
Edit: I'm running capcomalpha with fraux kernel and stock battery.

The following suggestion may be of no help in your case, but I've experienced something like this as well, mainly with CWM that doesn't support off-charging. The phone will look like its charging but is actually drawing just enough energy to keep the phone alive. Also, the charging light will turn off after 15 mins or so. One way to ensure that your phone is getting charged adequately is to check the screen; if you see an ultra-dim screenshot of CWM then you'll have to periodically remove the charger and reinsert it "restart" the charge. Then try to boot into android to complete the charge.
The phone is on I rebooted it and it jumped from 55% to 68%

buy a new battery and wall charger so you can charge the battery outside the phone.

You bumped a thread that was still on the first page after only 7 1/2 hours? Please don't do that again, not that I agree with bumping threads, but it is for when something needs brought back to the first page, not while it is on the first page.
do your have a case on? the trapped heat is cause the phone to slow down charging. it is a safety feature. off the case and flip over when charging. it should charge faster.

The phone has no case and was on the table so i guess there was nothing to make it overheat. Sorry for the bad bump i guess i was just desperate.

What version of Recovery are you on and as you said your using faux kernel. Try to revert to stock recovery or stock kernel and see if there is a change or behavior of your phone. And try aand see if fastboot is check on your power under settings..
you said it was hot. maybe you have some app in background using cpu. hence power drain and overheating.
Sent from my HTC_Amaze_4G using xda premium
Ok i swithed to stock kernel and its doing the same thing. I reflashed the rom and didnt install any apps to see if thats the case. I also noticed ita doing it only when the battery is low- 10% or less. Then the phone heats up and its barely charging. If its above 50% it charges fairly quckly and doesnt heat up. Ill see how stock kernel does tonight and report back.

Thats a rogue app causing the high android sys.
+1, I've seen this on 2 handsets.
Using GSam Battery Monitor, then clicking on app usage ->android system -> manage -> clear defaults
The above seems to stop the issue after a reboot. I've not seen it happen again since I did that.
Correct me if I'm wrong, but 9hrs and 47% left doesn't seem like a problem... if you take your phone and leave it on (with screen off) and wait until it dies then charge and turn on you will see that the "system" eats almost all your battery. There is nothing wrong with your phone unless you used it a ton and the system still eats all your battery which If that is the case and it's been 9 hours and had 47% battery then I would think you were doing MUCH better than most, imho.

any ideas? seems like xda needs to be manualy killed or it ends up using alot of resources in the bacground
I have seen the same on my phone, but it has not happened consistently enough for me to narrow down the possible cause...
Happened to me once so far. Charged my phone to full and went to work. I didn't use my phone for anything other than to check the time. I started noticing that the back of the phone was getting very hot, more so than when charging. I pulled my phone out and the battery was waaay down :
Hasn't happened since (fingers crossed).
Edit: I guess mine wasn't the Android system, but cell standby.

The fix for the cell standby drain is easy, see here: http://techsplurge.com/10665/solution-samsung-galaxy-s3-cell-standby-battery-drain-problem/ As for the android system drain it seems to have resolved itself. I still get alot of kernel wakelocks from bam_dmux_wakelock though
Ok, after I rooted I seem to be having a strange. Battery issue .. anyone have a fix for this? (I user antutu to control CPU and for now I'm busting using it to monitor+ dropped my phone iinto eco mode ( where it usually is) I can counter bat loss by doing the normal stuff but I never had to do.anything other then turn off data before... and even then... but from 10:50 pm to 2:40 am the phone went from 90% to 12% . And that was ..( eco was off) lol ... but I have never had that happen. Before even with that.
Thanks for any advice

75% it was on the whole time...even though screen was off....
This is the screenshot its a straight drop over the hours mentioned ... slope stays steady so its Constant power drain until I noticed ( you can see on the graph)
None of those apps were open, and I had done a restart right before. ( I fell asleep which is why I know I wasn't using it)

On top of the screen i see the skype is running in backgroud..
Just sign out from skype and also close wifi..
Try it bcz to know the exact battery issue trial and error method of clossing apps is best.

Skype and Words with Friends destroy battery life if you don't completely kill them. Show us the top of your usage stats, not the graph.

Right after I rooted mine I had terrible battery as well. I ended up reformatting (not wipe, actually formatting my system and caches) and then installed my rom again, fixed permissions and my battery life has been amazing. If I don't use the phone my battery maybe drains five percent all day long. If I use it a lot it will last most of the day as well.

The other thing you should check is you fast dormancy.
If you're flashing custom ROMs it's best to do it at a FULL 100% charge. In the past, before I started doing this, I had major battery life "problems." My phone would drop from 100 to 1 in a matter of hours and just hang on 1% for hours on end. If you haven't done this, download Battery Calibration, turn off your device and plug it in. Once it reaches 100%, turn the device on, run the app, and restart your device WHILE STILL PLUGGED IN. Once everything settles you should be good to go.
