Try installing Better Battery Stats and look at wakelocks and alarms to see what is draining your battery.

actually every thing is working fine but the problem is in the network when i set radio off it drains less battery
tried almost 7 radios but still the same but one thing is strange when i change the sim it goes from 60 ma to 40 ma but not to 10 when i put it into aeroplane mode it goes to 1 or 2 ma tries every thing but dont know what is the problem fresh rom , ruu but still it drains the same battery on every rom.
You have gotten several suggestions and ignored them. Good luck to you then.
as i said i hv changed my battery , rom and wakelocks and alarms are not draining battery actually its some how network problem because i use another sim of same network but it was 60 ma and when i insert sim of other network it goes to 40 ma. I dont know what is the problem
Battery calibration anyone succeded?
Hi I have a battery calibration problem on my GT-N5110 Note 8.0 that I bought refurbished through amazon. I know it is the calibration since the battery usually drains pretty fast and when it gets to 1% it stays there for around half to one hour of continuous use. Also sometimes when I'm charging it, it jumps from around 60% to 100% and "charged" shows up right after that happens, when I unplug it and use it, then it goes down normally (fast) 1% at a time, even though that big jump while charging happened.
I have tried several "full cycles" without success and haven't been able to find a real way to calibrate the battery meter, neither here or on google, and since I didn't buy it in my country, local samsung support say they can not help me.
I'm on 4.2.2 leak rooted and the drain has been present since I was on 4.1.2 stock.
If someone can get a hold of how to calibrate, it would be really nice if you could share it! Thank you!

I tried the battery calibration app before, and really didn't do a thing for me...
I also suffer this weird battery behaviour with the device charging, it will take ages up to about 60%, and then instantly its at 100%
I also get this on the way down... when im using it, the battery drains fast, but when I get to 35 -40%, I then suddenly get the low battery 15% warning flash up, and then im all out of juice.
This is the same whether im on 4.1.2 or 4.2.2 custom or stock firmware
I rarely get more than an hour screen on time, and thats with fairly low brightness and power saving mode on
If someone could some how contact Samsung and ask them about the real calibration it would be very helpful for us having this issue... Since some don't live in the US and don't get the correct support :what:

Battery decreases so quickly when wifi is on! hardly get a days use out of it...:crying:
One method described in the battery performance thread which I've found effective:
"I wanna share my trial of battery calibration that really make a significant different at least till now .. I used to make calibration by discharge / charge cycles, but this time i add an official instruction of Apple:
- discharge the battery by ur normal usage till 1% then let the device play an HD movie till it shut down (that may take some time as it for me takes 4 hours!!) then turn it on to make sure the battery read 0% (my previous calibration the battery always shut down at 1% and I never see that 0% as I was discharging it vigorously) after making sure it is 0% it will turn off by itself anyway.
- now leave ur device turned off for extended time (about 5 hours or more is better according to apple "u could let it while u r sleeping"
- after that turn the device on and plug it in as it is on
- left it charges as it likes (for my trial it takes 7 hours and didn't say charged!! but I had to unplug it as I had to leave the work!)
till now my battery is really significantly improved, hoping to continue like that and I will keep u updated
Hope that helps :good:"
Discharging it completely, leaving it dead overnight then giving it a full charge by plugging in as a soon as it powers on has yielded good results for me. However I've also discovered a severe battery drain bug in stock Kitkat which has nothing to do with battery calibration; using wifi on certain routers causes Android OS wakelock which persists in deep sleep. I use my old Galaxy W as a hotspot for my Note 8 and consistently my battery drains overnight in deep sleep with wifi on. At my workplace we have a Linksys E2500 router, I leave the tablet on wifi throughout the day and don't notice the Android OS wakelock. So if you're having inexplicable battery drain test your Note 8 on different routers.

Calibration is a myth... google stated calibration tools do not help with how Android functions with battery management.
I posted my thread about battery and charging cables, and replied an a few topics like this one, yet nobody will search on Samsung DVFS disable or take note of it as being the cause.
Root with saferoot if you have not rooted, install xposed framework if not done so, and Wanam Xposed or Wanam DVFS disable. Since over 10 months now, my battery stats and performance are trouble free.
I was having severe battery drain for a while until I tried something I read about. What you do is carefully open the note up and disconnect the battery for about 15 minutes (they recommend a longer time but I don't see the need). Connect it back up and put the note back together.
It worked for me.
Google it, there's even a video on how to do it.
I was down to 3 hours or so of battery time but bought a replacement battery from a company called New Power 99. Cost $65-ish US and now I can go all day and still have at least 25% when I hit the sack at night. Huge improvement for me! I"m not a heavy user but I take notes at work, do some surfing, then read and surf alot at home at night. So far it's been great! Might think of a replacement battery. Probably cheaper one's out there but I wanted to get what I paid for so shelled out the extra.

Hi! Thanks for the info! That's great to hear, one question, did you change the battery yourself? If so, could you provide a hint on which guide you used, that would be verry helpful:good:
The battery came with a DVD that explained it (with really bad music) but the bottom line is you pry the back off, take the 8 screws off, unplug the old - plug in the new and replace everything. Not really hard but, as I said, nerve-wracking! I was afraid I'd screw it up but it was pretty straight forward.

That's awesome I would like to buy the same one in case something goes weird and need instructions to follow. Do you remember anything about the seller/model/site you got?
Yeah, just go to Amazon and search for "new power 99 battery replacement kit". Then pick Note 8 from the list. eBay has them too.

Will do! Thank you very much! [emoji4] [emoji106]
Any time. Hope this works for you. It did for me.
I. Had the same issues, I just took off the back cover and disconnected the cable that connected the battery. I did not need a new battery. The toughest part for me was disconnecting the battery cable... I actually had to take out the 8 screws that held the battery in place, so I could get some leverage. I only had my battery disconnected for only 5 minutes and it solved the problem for me..... Good luck!

So, my battery is wack... and I think it's only been acting like this since I went to a KK ROM? Maybe? Feels like it...
I've had this tablet since it was released last fall, and this behavior is very recent.
Anyways, it dies FAST. Like nose dives in a matter of 5-15 minutes. What's even weirder, is that sometimes, if I power cycle the device, it'll jump up by 30-60%. But then just dies again in another 5-15 minutes.
And there's a screenshot after I just power-cycled.
It jumped from 11% to 71%!!
Crazy!
I've also tried letting it get to 5% then charging it to 100%, done that twice. No luck. I don't know if this is related, but if I power it completely off, and plug it in, it turns on... kinda weird. My Note 3 doesn't do that, it just stays off and shows the battery charge indicator.

Hi, I have similar problem and I am with 4.3 android. I have battery loss when I play games. It drops to 2-3% really fast and after reboot it goes up to 35-40%. Once I fully depleted my battery and charge it. This time there were no battery lost. After the second charging problem persists.
If you manage to fixed it please tell us how.

I have a similar problem with my p600. the tablet is new, got it since a month or less.
at first i was amazed of the battery life i use it a lot for work writing documents and sheets on excel, battery used to perfom quite well giving me more than 5 hours of screen on, but recently the battery starts to drop very fast, now i can barely get around 2 hours of screen on.
i've already done 2 cycles of full discharge and then charge it completely with the tablet turned off. but the problem stills.
also sometimes when i reboot the tablet the battery goes from i.e 20% to 40% after the reboot.
im still looking for a fix or solution, today i found a new official firmware for my model (4.4 firmware for telcel mexico). going to wait until the tablet is fully charged and then flash the new firmware. I dont know if its going to help but i got nothing to lose.
by the way, sending it to semsung is not an option because of knox 0x1

try this, bring life back to battery. If you use the trial version, keep exit and redo it until all cells are done.

Well unfortunately this has not worked....battery is still tanking. last night i played plague for 30 minutes....in 30 mins battery went from 90% to 25%. I think i will try reflashing KitKat....maybe my original update was screwy. If that does not fix it then I guess I will have to call Sammy.
Man i ha e exactly the same problem. I calibrated it some months ago and it seemed to work fine. Now the problem is back.... Dont know what to do... I have tried several apps, though i read google doesn't recomend to use any app to fix the battery... we really need help here

Sorry to bump this, has anyone found a solution yet.
I've replaced the battery 3 times in about 9 months, but had this issue about a yr, was sent back to Samsung who changed the battery and supposedly updated the fw 4.4.2, I have since replaced the battery another 3 times every 3 months, each time either factory resetting or flashing a new rom, currently on official Smp600 5.1.1 BTU rom, today my battery was on 47%, I plugged in charger and was watching/streaming a movie on it, about 80 minutes later the tablet shut off, which was odd it's never powered off while on charge, powered it back on and battery said 19%, my previous issues has been the same as others, it can be on 100%, play a game, or stream a movie,or watch youtube etc and it will nosedive dramatically 20/30% at a time, sometimes within 10 mins it's gone from 100% to less than 30%, it's clear there's some sort of issue if others have it, I was wondering if a thread should be made to list ppl with this issue to see how many there are and go from there.

I've been having the same issue for some time now. Calibrating the battery does help, I don't experience the problem nearly as much after calibrating it. But it'll still nosedive on occasion, maybe once a week. This is the app I use to calibrate it https://play.google.com/store/apps/details?id=com.nema.batterycalibration
First two days I had the phone it had great battery. I was getting 16-18 hours of life with 4-6 sot. Now the last two days at work it's worse than my op2. By the time I got home yesterday I was at like 35%. Previous days I was well over 60.My android system is taking most of the blame. On my good days it was at like 8% when the phone would die. Right now with my phone at 79% it's already at the top with 5%. I've barely used the phone while I'm at work right now. It's been unplugged for 3 hours and my sot is 35 minutes. Not sure if it's got something to do with the ambient display. Maybe finger print scanner. Any one have ideas?

Humm I thought it was the other way around. Nevertheless I have WiFi at work. Can't remember if I was on it though. I'll have to test that out.
You don't have to run a custom rom or loose dash charge cause your rooted. I'm still using stock oxygen 3.1.3,and have the basic functions like dash charge working. I'm not sure if you have to be rooted to use gsm, cause I'm always rooted, but it may gave you more specific insight as to what exactly is draining your battery quickly.

You know the image you attached, with the graph on it? Tap that and check the Awake heading. Is it one long solid blue bar? If yes: your phone stays awake (doesn't go in deep sleep mode). Does restarting it make a difference (i.e. does the solid blue bar get broken up)?
The problem emerged on my OP3 as well yesterday AND I had it on my prevous phone (a OPO). On the OPO the problem was that it wouldn't release a wakelock that kicked in during charging. While I haven't explored the problem on my new OP3 enough to know if this is the same problem, here's what fixed it for me if the problem is indeed charger related: when charged to your liking turn off your phone with the charging cable still in. Once turned off, remove the cable and restart the phone.

Are you talking about under history details? I'll check tonight once my phone is drained. I did a battery cycle yesterday. Let it die and charged to 100 while it was off. We'll see how it goes today. And your saying it was an actual charger problem?
Heavy battery drain might have to do with the "pocket problem". The fingerprint sensor constantly activates and is not properly blocked by the proximity sensor.
There are several threads and posts about it, here and on the oneplus forums...

Yea I had that once in a while with my op2 I'd take the phone out of my pocket and it would say too many attempts at the scanner. Nothing on this phone like that though. And of course today is a different story with the battery lol its good today. So maybe it's while I'm at work. Idk it's odd. I need some more testing. Currently I'm at 9.5 hours on battery with 56% left and almost 3 hours sot. I'll see how this week goes at work and see if I can diagnose anything
I've been having this problem as well, losing as much as up to 20% of battery overnight, while it was doing absolutely nothing. I've tried a couple of things, but last night it 'only' drained 5%, betterbatterystats reports 0.6% of drainage per hour.
I think this is due to the weather option in the launcher, could anyone else try turning it off and see if battery life improves significantly?

You don't even need to do that. You can just check it after an hour or even less. Just put the phone away for an hour with the screen off and check history details.

Not quite. I'm saying it was a wakelock that kicked in during charging and that wasn't released when I took the phone off the charger. I don't know if it was the charger caused the wakelock.

I've at least disconnect the battery of my 2 years old note 8.0 twice. The first time was because the DVFS thing, and the second time just recently because I've installed CM 13, and the battery seems to need recalibration after that.
If you're brave enough to replace the battery, might as well try to disconnect it to recalibrate it first. Just to make sure that the battery is really dying.
