[Galaxy Note II General] CristiM74:
Hi guys,

Everything was working perfectly for me until a few days ago when I found exchange services draining my battery. I don't remember installing any particular application, anyway nothing related to exchange. Now 60% of the used battery was consumed by exchange services. What could be wrong? I have 1 exchange account configured for push e-mail during peak/off-peak hours, but it was like this since day one and exchange was barely using any battery.

What should I look for?

Thanks!
[Galaxy Note II General] thegregulator:
I often find a simple battery pull works. Although the problem may persist down the road.
[Galaxy Note II General] CristiM74:
Ok, thanks. I'll try that tonight before recharging. Any other ideeas?
[Galaxy Note II General] joshyth:
Yeah, just rooted
[Galaxy Note II General] CristiM74:
This is getting worst ... after 11 hours on battery with 30 min. screen on and 45 min. of calls I have 10% of battery left ... something is wrong ...

[Galaxy Note II General] skivnit:
for those having poor battery life, you must check that allshare is not enabled, that's because it is out o fthe box and its causing massive battery drain. I noticed it when i bought mine yesterday and switched it on. the phone was a bit hot then battery was draining i went to check some settings and found that all share cast been keeping my phone up for 45 mn..so i disabled it and now its all good. I also installed latest leak on my S3, yet same problem with all cast share which was on by default.

hope it helps
[Galaxy Note II General] dzontra11:

Hey guys, I need a little help.

I got my Note 2 yesterday and flashed Omega Rom using TWRP. I connected the original wall socket charger in the evening, and today it was only at 88%. Thats 7 hours of charging! Any idea what's wrong?
[Galaxy Note II General] MohJee:
When the phone is charging, go the battery stats and make sure it says (AC) instead of (USB). I think sometimes the software confuses the AC adapter for a usb and limits the charging output to 500ma. Plug the charger again and restart the phone then re-plug to fix it. Happened to me before.
[Galaxy Note II General] reservin:
I lost 20% during the night..

No sim card and Wifi on.
[Galaxy Note II General] xFrozen:
Probably watched videos. This phone can go 15 hours or more with just video playing!
[Galaxy Note II General] therockk:
That dosnt sound right. You should install WanamLite V1.5, & RedPill Kernel. Then download and install SetCPU and set the CPU Governor to Pegasusq, and IO Scheduler to Deadline. In doing so i get approx 30 hours on battery with 7-10 hours screen time!.

[Galaxy Note II General] reservin:
Well, we can see that in the middle you charged like 50%. It wipes when you fully charges.

Anyone can see that green bar where you charged phone.

why are you trying to fool people or do you really think you made 12hours on single charge?
[Galaxy Note II General] dzontra11:
Arghjj..what you doing man....12h..with charge..
[Galaxy Note II General] imkr1:
I agreed..... I from 6 to 7 hours is the most scientific and reasonable proof

For our beloved note2....
[Galaxy Note II General] Tuffcheez:
Doh! :banghead: Apologies to the community. I honestly thought my phone had accomplished that on one charge. I thought it records from the moment you unplug from a charge, not a full charge. Sorry guys, I'll try again. :o
[Galaxy Note II General] skivnit:
U can accomplish more but that implies turning the phone into a dumb phone i.e no wifi or data. No google now no emails. Then whats the point of hsving this beast right?;) i got 8 hrs on screen with 22 hrs uptime now im at 7 hrs screen time and 27hrs uptime
[Galaxy Note II General] jauhari:
Why I can't get that numbers. Maximum that I can get is 3-4 hours screen on :(

Any clue how to get yiur awesome number?

Im all stock (Kernel + ROM), nothing special really just froze some blot with tb. If i disable googke niw im sure i can squeeze out more juice. I think u need to check ur maps, and samsung back up and google back up, those can eat up a lot
[Galaxy Note II General] msx999:
amazing.
[Galaxy Note II General] CreepyDroid:
The charger shipped with the note 2 uses 2A instead of the usual 1A. 2A chargers are usually used only for tablets. Great move from samsung, a monster battery with fast charging is a blessing.
[Galaxy Note II General] barondebxl:
Haaaaaaa thats why it charges so fast. Thanks for the info. Youre right, a monster battery with fast charging is the best!

[Galaxy Note II General] adrian_nene16:
I unplugged the wired from the the note 2 at 2:30 pm, i came back at 10:45 pm and it dropped 1% pretty good if you ask me. Airplane on and wifi always on.
[Galaxy Note II General] barondebxl:
yep this seems to be about right. This is incredible by the way. Yesterday I had 17 hours on battery with 7 hours on screen time with 11% left. Nothing beats this phone when it comes to battery life. Ipad users, watch out!!!!!

Oh man, you will be amazed I promise you that.
[Galaxy Note II General] adrian_nene16:
That's pretty amazing!

big display plus quadcore with all touchwiz features with long lasting battery life, we cannot ask for more.
[Galaxy Note II General] freemini:
I am wanted to say I failed to drain the battery completely yesterday. It charged 10% while copying music so technically it would've died at 6h30m screen on. That's pretty damn good, I would accept that from a tablet but barely. As a phone, it's leaps ahead.
[Galaxy Note II General] barondebxl:
To give you an idea on how good this is, here is the nexus 7 tablet screen time thread

I wouldn't get a 7 inch tablet now. This has the same resolution, it's pocketable and lasts about the same.
[Galaxy Note II General] amg009:
Wow reading through the whole thread im so tempted to buy one..:D

Development 'l be my next concern.,
[Galaxy Note II General] tom369:
Guys you say it's amazing that the battery charges so fast at 2A, but isn't it so that at the same time the battery overall durability will be affected? I've always heard higher charging current diminishes total battery life, I don't know if this is still up-to-date info though.
[Galaxy Note II General] barondebxl:
Nothing to worry about. Its gonna be a great development community, we already have great devs like Indie who has released a rom for the note 2, same dev that has the most downloaded rom on the S3, omega. This phone is only 5 days old so lets just give it some time. Its gonna be awesome.
[Galaxy Note II General] mg35pt:
Both battery chemistry and charger intelligence have been improving. Notice, for instance, how the battery does not get very warm while charging or, also, how it goes from, say, 20% to 30% very fast but takes comparatively longer to go from 99% to 100%. So, done properly, fast charging is no longer such a big issue.

Number of charge cycles, on the other hand, still has a negative effect. With a good battery life we won't need to keep charging it so often. I'm sure this more than makes up for the fast charging effect. With minimal care, a battery like this should last longer than the average upgrade cycle for most users.

If not, we still have the advantage of a replaceable battery and a popular model. I'd bet getting a second battery a couple years down the line won't be very difficult.

Can anyone tell me if anything stands out here please
[Galaxy Note II General] skivnit:
U need to give us partial wakelocks
[Galaxy Note II General] hannsz:
I use data in and out to send messages and web browse. Only time I use wifi is to update apps.
[Galaxy Note II General] MohJee:
Your phone has been awake for more than 8 hours. What is the "Screen On" stats? The screenshot doesn't show it. If it's something like ~5 hours then you might be worried... that means the phone has been awake for 3 hours whilst the screen was off. If the screen on is 6 hours and the awake is 8 hours then the phone has been awake for 2 hours whilst the screen was off etc. It's simple math..

Then you compare that with your usage of the phone to see if it's normal. For example, I use the music player while the screen is off, so it is normal for me to see ~2 extra in the awake state than the screen on state.

If you see there is a wide discrepancy between the awake and the screen on, then check partial wakelocks and kernal wakelocks to see what has been keeping the phone awake. For example, in my partial wakelocks media player and audio is taking up more than ~2 hours for me, but I know that that is normal, since I listen to music whilst the screen is off.
[Galaxy Note II General] craigels:
I had used my phone for about an hour with music screen off. I don't see how some people get 5 or 6 hours screen time should I change some other settings I have my screen set to dynamic instead of standerd would that affect battery
[Galaxy Note II General] craigels:
How do I freeze apps
[Galaxy Note II General] Tuffcheez:
Did you charge it in between out of interest? Your graph is showing an upward peak like mine, which apparently means it was charging at that point.
[Galaxy Note II General] MohJee:
Your kernal wakelocks indicate that you've been using data network for a considerable amount of time. All people who get 7-8 hours screen on have used Wifi instead of 3g. 3g consumes much more power than wifi, so you can't expect to reach those results on 3g.
[Galaxy Note II General] EvoYas:
No I couldnt charge it at all i just to9k the phone and left because I wasnt planning on going for the whole day so I didnt charge it in between.
[Galaxy Note II General] EvoYas:
This is the setup but the main reason why I get good battery life is because mostly I am connected to wifi.
[Galaxy Note II General] hannsz:
About 9 hours of my 10 hours screen on was on 3G. Wifi kills my battery much faster.
[Galaxy Note II General] Tuffcheez:
Then could the people who told me that I had charged my phone in between please explain these results?
[Galaxy Note II General] MohJee:
That's strange. It's the opposite for me. Maybe it differs from network to network.
[Galaxy Note II General] craigels:
I use data when out of home and in work as I don't have access to wifi should I just turn off data unless I need it then
[Galaxy Note II General] sohebq:
Finally decided to test out the power saving mood, I turned it on when phone was 80%, so here are results. I feel I got 1 hr extra screen on time but on the other hand it slowed down the phone as well, I can, t play graphic intense games.

2hr full hd video playback

40 mins facebook browsing

30 mins xda app

Downloading, played games for a short time as well

Hi,

I have used the power saving in these days, i played about 2 hours with 3d games (gta3 and nova 3 and max payne) and still i was able to reach over 1 day uptime and 8 hours of screen on with apparently no slow performances on graphics, just a very very little less smoothness on home and drawer transitions, but ingame really no differences with full power mode.

[Galaxy Note II General] sohebq:
Actually I only played NFS: Most wanted, it was lagging, hence I said this. Yes, the app drawer scrolling was a bit laggy too.
[Galaxy Note II General] emprize:
what did u use in power saving mode? just cpu? all checked?
[Galaxy Note II General] Tarzan-:
I assume just the stock power saving option (Toggles/Settings)

On the side note. The beast got an excellent battery and screen. I managed to get 17 hrs without charge with 6 hrs screen on, NFS for 2 hrs and a Live Wall Paper.

Will post screenie later.
