I imagine it's OK to leave it plugged in. Every phone I've owned I plug in at night right before bed and unplug before I go to work. So they sit on the charger for a good 7 hours. My wife does the same with her iCrap and we've never seen any ill effects.

I get amazing battery life...stock rooted plugged it in 3 times to transfer a file for less than a min on usb
[Sprint Samsung Galaxy Note II] teco2010:
Damn... how did you get that? I got a maximum of 33 hours and only 2 hours screen on. I'm on stock unrooted. Maybe due to my phone being new still the battery is not optimized?
[Sprint Samsung Galaxy Note II] kwazytazz:
My phone is new too. Less than a week old so im pretty sure its not optimized neither. I didnt do anything special on the phone to obtain better battery life all stock and just rooted
[Sprint Samsung Galaxy Note II] teco2010:
Are you using CDMA only or is it on CDMA/LTE.. do you have LTE?

My area sometimes 3G is really fast and sometimes really slow.. I think they might be upgrading this area to the new network and messing up with the towers, I don't know. North and south to where I am LTE can be picked up. This could be affecting my battery cause my weather widget was refreashing for a good 2-3 minutes..

Today thgough. I lost 25% in 2 hours mostly in idle... but my signal was really poor even going to roaming sometimes... this was at a friends house.
[Sprint Samsung Galaxy Note II] kwazytazz:
CDMA only, dont have lte where i live yet but even with CDMA service is spotty as i was in a area where sandy hit

This. Screen on time is the only relevant information.
[Sprint Samsung Galaxy Note II] theoner1:
Screen on time doesn't mean anything either. Let say someone just turn the brightness down to 10% or lower and all they do is read book on their device, just saying. Don't get me wrong, this phone blows all others out the water when it comes to battery, I absolutely love this thing.

[Sprint Samsung Galaxy Note II] XxLostSoulxX:
i assume stock battery correct? and screen on time?
[Sprint Samsung Galaxy Note II] asrebel:
Is 20% remaining after 11 hours good or bad (assuming usage was 80% wi-fi, listened to a couple songs, and read a few e-mail messages). In my opinion, it's not that great. I'm on de-odexed stock with the multi window app hack, but I'm not sure it was better before those changes....
[Sprint Samsung Galaxy Note II] DarkManX4lf:
Doesn't sound too good. How long was your screen on?
[Sprint Samsung Galaxy Note II] dtugg:
Yeah not too good unless the screen was on most of the time. I get like 6 hours of screen on time. That will include a lot of web browsing (white uses a lot of battery) and streaming Netflix over 3G.
[Sprint Samsung Galaxy Note II] JPLOWZ:
Update Change for the worse???

I agree ever since I did the update definitely noticed battery change for the worse.. Im not rooted.. I have the same apps I had b4 the update. Lastnite it was 100% at 830pm woke up at 530am dropped to 90%. How can it go down 10% when not in use.. B4 the update it would drop 2-3% overnite.. I noticed android system increased.. I tried to reformat sd card.. Not sure of any results. But in 2 hrs since 100% after reformat its at 96% android system at 17% and android os 12% which seems like its still on the same course but im using it so i can understand the loss in battery..But what do you guys think.
[Sprint Samsung Galaxy Note II] DarkManX4lf:
That looks much better.
[Sprint Samsung Galaxy Note II] asrebel:
Great question. I'm not sure anymore. I can say I'm at 80% right now after 3 hours, and my screen has been on 29 minutes.
[Sprint Samsung Galaxy Note II] madsquabbles:
i've noticed terrible life too. somehow it says i've deep slept most of the time but the drain is crazy! it's about 1% per 5 minutes of doing nothing. i tried downgrading the modem and it fixed nothing. also tried different kernels with no change. i've reverted back to JB 4 and gonna check if it's still acting up.

JB 5.1 has been installed fresh 4 times already. once going completely from stock. i've not run the update stock, so i can't compare the results with it.

update - after 30 minutes i lost 6%. so, something else is screwing with my system. gonna do a odin back to stock and start over again.
[Sprint Samsung Galaxy Note II] yellowman82:
Well I just put my phone to charge right now and this was my result since yesterday.
[Sprint Samsung Galaxy Note II] intelli78:
I am on rooted stock LJC and having the same issue - unreasonable battery drain even when the phone is of and supposedly in deep sleep. It wasn't like this when I first got the phone. Any theories? Wiping and reinstalling does not seem to help.
[Sprint Samsung Galaxy Note II] madsquabbles:
just a guess, but maybe the battery calibration just goes wonky sometimes. today, after doing nothing, it's back to normal. i was planning on wiping the battery calibration but it doesn't seem like i need to now. nothing in any of the monitors showed any app messing with the phone going to sleep. deep sleep was only 30 min less than up time.

maybe the samsung cover with the nfc support may be draining the batter for some reason. the next time the drain starts up i'll swap covers and see.
[Sprint Samsung Galaxy Note II] mxl180:
I notice my phone wouldn't sleep when off... issue was wifi being on and constantly searching for signal.
[Sprint Samsung Galaxy Note II] KB112:
I've been very pleased so far. I had to charge my Evo and my 3d by lunch time or it would be cashed out. Currently at 8% with 11hrs run time and just shy of 5hrs screen time. That's amazing for the signal I get at work.

Edit - I have no wifi at work either.
[Sprint Samsung Galaxy Note II] bill323:
I am very happy with my battery life. No more worrying about the phone taking a crap mid day. I keep everything on too, GPS, Bluetooth, WiFi and I update my emails every 5 minutes. The only oddball thing is I lose about 13% of my battery life overnight even though its cruising on WiFi.
[Sprint Samsung Galaxy Note II] intelli78:
Any updates? My severe drain also resolved, seemingly idiosyncratically, but I'm not sure it's really back to normal. I posted a longer account in the thread "what happened to my battery?", where someone else reported the same problem.

There is definitely something going on, just don't know what. That's always the problem with battery issues, nearly impossible to isolate cause by changing one variable at a time...would take forever and a day...
[Sprint Samsung Galaxy Note II] DarkManX4lf:


I've got the same problem. I only got the phone yesterday so it already had LJC. I am also on rooted stock rom.
[Sprint Samsung Galaxy Note II] Skripka:
If you can live with it disable Google Maps...it issues thousands of partial kernel wakelocks IME. Means that just sitting on the shelf while you sleep you burn off 12-15% more battery tjan you need to.
[Sprint Samsung Galaxy Note II] madsquabbles:
nothing yet. everything is back to normal. when i first got it, it was draining incredibly fast no matter what rom i used. i blamed battery monitor widget pro because it seemed immediately after uninstalling it would go back to normal. tested that 3 times with the same results. i'm using bmw again with no adverse affects. there haven't been any changes to bmw but i did update the firmware/radio/baseband.

i'm just guessing there's some occasional screwiness with the calibration.
[Sprint Samsung Galaxy Note II] DarkManX4lf:
Tha ks for the advice but I shouldn't have to disable Google maps. At the rate I'm going, I'm getting the same amount of battery life as I do with my Galaxy S3.
[Sprint Samsung Galaxy Note II] Skripka:
Install BetterBatteryStats. Go look for what is issuing tons of kernel wakelocks. For me didabling Maps made the difference of being 100% charged going to bed and 75% left when I woke up, and 95% when I woke up.
[Sprint Samsung Galaxy Note II] intelli78:
As an update from me, I too disabled all location services this morning, and battery life is one again excellent, like when I first got the phone. Also, Iam finding that being in a poor Wi-Fi area seems to contribute a lot to drain.

I wouldn't say we have a definitive answer yet, and there seem to be multiple causes, but these factors at least seem to be big contributors to drain. Hopefully whatever is going on with maps is resolved in future software updates.
[Sprint Samsung Galaxy Note II] loveshinesthru:
I noticed when I am away from the house, my battery drains quicker. I will have to remember to turn the wi-fi off when I leave.
[Sprint Samsung Galaxy Note II] decke003:
Very impressed so far

This was all on LTE. Most of it either surfing the web or watching YouTube.

[Sprint Samsung Galaxy Note II] theoner1:
Stock or rooted?

That is pretty impressive pal. This phone have the best battery of all phone over cellular data.
[Sprint Samsung Galaxy Note II] DarkManX4lf:
Ok I'll give this a shot. Do I just install better battery stats and leave it alone? Then just wait a day and check the records? Or do I have to setup something in the app?
[Sprint Samsung Galaxy Note II] Skripka:
Needs root. Run it once...you'll occasionally see notes about it being granted root permissions. Let it run in the background and check it after overnight for partial wakelocks in particular. I remember seeing similar bad wakelock behavior draining the battery on my evo4g long ago.
[Sprint Samsung Galaxy Note II] theoner1:
root is not necessary for bbs, need root only to check alarms and network status.
[Sprint Samsung Galaxy Note II] DarkManX4lf:
Ok, I'm rooted. The weird thing is once I installed this app I was getting a lot of random reboots. I flashed back to LJ1 stock and rooted again. I lost all my backups and data sucks here to download anything from the google play store. I'll have to try this tonight. Hopefully it wasn't better battery stats that was causing the random reboots.

Should I reset the phone?

Other info:

Never rooted either and new one runs hotter which explains the faster drain. Using same battery on both. Keeping other sealed for now.
[Sprint Samsung Galaxy Note II] emeraldayotte:
Getting RIDONKULUS battery time using wifi over 3G. The other day I was on pace for 23 hrs and still had about 15-20% left (didn't take screenshot unfortunately).

I just realized that today have abnormally heavy use, that I got the 15% low battery indicator for the first time since owning this phone. With the OG Evo, this was happening by lunch if I didn't have a charger and 1/3 of the usage.
[Sprint Samsung Galaxy Note II] intelli78:
What ROM?

Screen on time?

Better battery stats log?

If you can provide these, it will bring us closer to a solution. :)
[Sprint Samsung Galaxy Note II] loveshinesthru:
stock unrooted, im not sure I didnt look- estimate 2 hours? dont have better battery.
[Sprint Samsung Galaxy Note II] intelli78:
Really, the more I research this, the more it seems jelly bean just has a problem with maps killing battery life. I am increasingly doubting any Note-specific issue. Seems Google needs to refine the Now suite and other gps based apps. Just look at what Google turns up. ..

https://www.google.com/search?hl=en....0.0.0.0.0.0..0.0.les;..0.0...1ac.ROqgK3arJz4

so, Loveshine, on second consideration I would actually suggest you try turning off location services _before_ worrying about BBS. Uncheck all the boxes in settings-> location services and let us know how your battery is tomorrow. I have a feeling it's going to be greatly improved.
[Sprint Samsung Galaxy Note II] loveshinesthru:
I also hate how google just picked a random place for my work. I dont work and it was always telling me how much time it would take to get to work. now if I go into town it tells me how long it will take me to get home even though I am not ready to go home yet. It drives me nuts! I couldnt just clear out the address for the work, it wanted an address.

I will let you know how it does tomorrow.
[Sprint Samsung Galaxy Note II] Skripka:
It is only Google Maps IME that issues crazy amounts of partial kernel wake locks...before I just took to disabling gmaps, one night while I slept for 7 hours it issued 3000 partial wakelocks just as a background boot process. In disabling gmaps app I go from unplugging with 100% at 10pm and going to bed and waking with 75% battery to 95% battery. Apples to apples, stock ROM a ll elsr equal.

I remember similar gmaps behavior on my old evo4g. All the othe Google Now apps behave fine IME. Location services otherwise aren't a problem, , battery life wise.
[Sprint Samsung Galaxy Note II] intelli78:
Interesting. So how do you disable maps while leaving the location services running? Do you mean freezing it with titanium or sth?
[Sprint Samsung Galaxy Note II] Skripka:
Apps manager in settings. First all updates need reverted there before the disabling option pops up. At least I'm remembering it that way for the stock ROM. All location services seem to be indifferent to whether maps is disabled. It is gmaps itself that does it rather than location services.

Since we're talking about battery life here... out of curiosity, how long is it taking everyone to get a full charge on their device?

I've been charging now for about 7 hours and am at 85%.....
[Sprint Samsung Galaxy Note II] Skripka:
I'm fairly certain the 2A rating of the stock charger is not accurate...my 2A Touchpad charger can fill my n2, powered off, from zero to full in about 2.5 hours.
[Sprint Samsung Galaxy Note II] loveshinesthru:
It only takes about a couple hours with the stock charger.
[Sprint Samsung Galaxy Note II] mideastbeast:
Loveshinesthru, go to settings, applications manager, Swype from right to left till you get to "All" then go down to the "Talk" app ( which is Google's instant messenger). Click on Talk then click disable if you don't use that app . That app seems to be a battery killer.
[Sprint Samsung Galaxy Note II] Savoy2001:
Guys just a fast question. Why would my stock gallery app be taking up approx 7 hours awake time in my batter use list? Phone was off the charger yesterday for 15 hours and 7 of those had the gallery with awake time? I've never seen this before on this device or any other Android device I've owned. I'm running completely stock. No odd ball picture apps installed etc. I did install 2 picture apps from the pay store but they are un installed and have been since before yesterday. Ideas?
