Can someone analyze what trouble spots I might have here? I have not had good battery life since day one no matter the kernel or firmware.

There is no calibrating Li-ion batteries.
[Galaxy Note II General] TopSOUL:
This is my current "record". I used the phone without mobile data enabled, only used WiFi when needed. I also enabled flight mode at night (from 11 PM to 6 AM).
[Galaxy Note II General] Laynee1:
The hell!!!!

Your battery life rocks.. What rom and kernel are u using? Anything else disabled on phone? Sync? Explain please
[Galaxy Note II General] TopSOUL:
Yes, I pretty much disable every radio on the phone unless I need it (this includes bluetooth, GPS, mobile data, wifi and as i mentioned before i turn on airplane mode at night) and also disable sync, they turn on automatically when i plug in (tasker profile). I keep brightness on automatic on the lowest level. I managed to have the screen on for so long by using apps that don't require that much processing power (I played some trivia games,watched some videos in the default video app). Otherwise i get around 7-8 h of screen on time per charge.

Not seems, definitely. I used to come here to post 9 hours screen on time, now I'm finding it hard to reach even 7 hours!

That's the cost of of some gimmick goodies like ink feature and Exynos Sudden Death fix I guess.

so preventing my phone to explode results in ****ty battery life? yeah that's an awesome update. could someone write to sammobile about this?
[Galaxy Note II General] jordanprudent:
Recent battery stats, 100% brightness, live wallpaper, Dropbox Facebook Gmail and Skype signed in with push active, gps, maps all features of note 2 enabled etc in other words not battery efficient at all.

It's decent considering the phone use, obviously could be better

[Galaxy Note II General] adytum:
That is pretty darn awesome, considering your usage and settings. Seriously, two days on max brightness, and still the screen on time is what other phones would struggle to achieve in twelve hours.

I am on cm10.1, finding battery life similar to omega v9.1 that I was on before.

Everything is stock
[Galaxy Note II General] kylec:
All stock. I charged a bit towards the end but otherwise not too shabby. Used quite heavily today as you can see from the awaje and screen on times lol.

Wifi, data, bluetooth, autosync, autobrightness, nfc, gps always activated at all times and all accounts (facebook, email, gmail, viber, google+, twitter and instagram) all set to push. I like to make sure that I get all my information as soon as possible. :)
[Galaxy Note II General] tyler78:
I'm at 50 percent with a screen time of 4.4 hours. Just amazing. I love this phone.

[Galaxy Note II General] MohJee:
ARHD 6.0.

Persues kernal 27.5

12% left just put it on charge
[Galaxy Note II General] xamou711:
Mohjee what il your utilisation please ? :)
[Galaxy Note II General] MohJee:
Nothing that demanding

Whatsapp chatting

Reading news etc..

Playing some chess games

Wifi on at all times except when I sleep

Brightness set to around 1/5 because I was mostly indoors

Mind you that was from 95% to 12%. I coulda had a bit better usage if I did from 100% to 1%. I recommend Persues kernal it really made a difference for me.
[Galaxy Note II General] plotinus:
What are you perseus kernel settings? Would you mind sharing them please
[Galaxy Note II General] MohJee:
I didn't change any of the settings. Just chose Persues kernal in aroma installer that comes with arhd 6.0.

What is your rom and kernel please ?

Can you explain what you do to underclocking please ? :)
[Galaxy Note II General] BullHorn7:
After a while of tinkering with roms and crap, I went back to stock and just disabled some bloatware and may Autostarts from some apps like eBay, GMaps and GTalk. I'm satisfied with the results.

Roughly 5 hours of screen time. At 12% I could either have it idle for another day or use the phone with the screen on for 40 to 60 minutes. :)

And lastly i have disabled location services, sync service when im on battery( with the help of tasker i enable them when charging)
[Galaxy Note II General] el_roy1985:
On 4.1.1 I would usually get to 14 hours with 55-60% battery left. Since the update two days ago, it seems when I get to 14 hours I am now closer to 35%. This is a considerable amount of difference and quite disappointing so far. Hopefully these last few days are just a fluke, but I don't think they are. If anything, my usage is lower then what it was when I was getting longer battery life on 4.1.1.

I guess another week or so of use will show the truth of whether it's better or worse.

I do not do all the extra steps to extend battery life. I just use the phone with wifi on all the time, gps usually off, auto brightness at full and with whatever programs that wanna run in the background, running in the background. This is how I've used the phone since I got it, because I want to test real world battery life.
[Galaxy Note II General] EarlZ:
8hrs screen time and still at 50%, thats amazing! Wish i had that kind of battery life.. Id normally get about 10-12hrs screen time at close to power off with my Note2 and other previous devices ( Galaxy S,S2,Note1 )
[Galaxy Note II General] snip3r77:
Basically I charge daily. Screentime is like 4hrs and before I sleep Battery will be left at about 10%.

I got a feeling 4.1.2 is sucking more juice than 4.1.1 .

What do you guys think?
[Galaxy Note II General] fade2black101:
Hi mate

I would appreciate it if you explain how to disable location services properly? This is causing my phone to keep constantly waking up when on standby.

Thank you.
[Galaxy Note II General] Fostil:
Simply go to Settings> Location sevices and disable all 3 options. Also dont forget set wi-fi sleep mode: Settings> Wi-Fi> Advanced> Keep Wi-Fi on during sleep>Only when pluged in. That way phone should not wake up at night when you sleep and in battery history you wont ever see any wake ups. :)
[Galaxy Note II General] fade2black101:
Thanks for the advise

It's a shame really that the location services drain the battery so much on sleep. It never used to be like that and I'd kinda like to keep them on.

Similarity I need WiFi on at all times for emails and whatsapp.

WiFi never drained much on my old HTC EVO 3D. It's a massive shame about the locations bug. I hope they fix this soon.
[Galaxy Note II General] EarlZ:
I've never had issues with the location service keeping my device up altho I turn off the GPS when I sleep and I dont have 3G on my Note 2
[Galaxy Note II General] fade2black101:
I turn GPS and data off too, and have my network set to 2G most of the time. But my phone is constantly being woken up.

Getting a bit annoying to be honest.
[Galaxy Note II General] Fostil:
Have you changed wi-fi sleep mode? By default wi-fi is turned on even at sleep time.
[Galaxy Note II General] adytum:
The culprit is usually not location services themselves, but Google plus. If you don't use Google plus, location services shouldn't be draining much battery.

What's your screen-on time? Looks normal to me if you've used the phone which you seem to have as in surfed quite a bit?

I love the battery life on this phone! Over 5 hours since I took it off the charger. I have recieved two phonecalls and looked around in the system just a little bit but not much. Battery is on 98% now when lunch is over at work.
[Galaxy Note II General] myfinalheaven:
Here is my second run of my battery. Everything on most of the time.

Nothing is off except wifi for a bit.

Sync is on for mail, have facebook push, whatsapp, Instagram on all day and music playing on the commute home.

Pretty damn happy with it. Lasts a whole work day literally without being worried at all.

Any tips on improving it? I'm on completely stock HK version but using it In Australia.

Almost 7hrs but that is with lots of downloading. Probably can get 8hrs with normal use on stock odexed 4.1.2 rooted.

Brightness on 75% all the time too.
[Galaxy Note II General] iampunX:
On stock rom 4.1.2

Minimum brightness. 2G. With data synch. Music. Some clips at full brightness. Some minutes of gaming. I'm really satisfied with the battery considering the amount of apps that's running in the background. Not to mention Skype that's always running. Wifi and gps enabled.
[Galaxy Note II General] jauhari:
Wow that's really awesome.. on me the maximum I can get is around 4hours... I don't know what's wrong... any clue how to get like on yours please?
[Galaxy Note II General] unholygid:
1.Disable sync on all apps. Eg email are on manual, camera uploaded to drop box only on wifi etc.

2.Drain battery to zero and charge it over night (done only once after flashing/upgrading rom.) After that I use it per normal.

3.Download es task manager and disable unwanted startups.

4. Removed some bloatware like chaton, samaung sync etc. You can freeze them.

Hope I helped a bit

[Galaxy Note II General] KLUVJ:

[Galaxy Note II General] Fostil:
1 suggestion: Go to Settings> Wi-fi> Advanced> and set wifi sleep to when charging. That way you will save some battery, because now your wifi keeps on even during sleep time.
[Galaxy Note II General] jauhari:
How to show up setting WiFi advanced?
[Galaxy Note II General] fade2black101:
Are you using any apps such as juicedefender? If so, what tweaks have you applied.

I've disabled and removed so many apps, but still cant get my phone to sleep consistently and it wakes up randomly when screen is off. Yours seems to wake up periodically every hour or so and then go straight off.
[Galaxy Note II General] KLUVJ:
nothing. battery saving apps are of no use mostly. i never turn off data or wifi, and screen is kept at 50% brightness. try using betterbatterystats to determine which of ur apps are doing the wakelock. my wakelocks are mostly email stuff which i like to leave on. :p
[Galaxy Note II General] fade2black101:
Well I've seriously done so many tweaks. I'm guessing it is ebay and whatsapp which are responsable fof the wakelocks.. Even though my HTC can go all night with barely losing a percent where as this will lose 5-10%

Jellybean/Samsung software seem to be the culprit.
[Galaxy Note II General] KLUVJ:
ya, my hox used to go 10+ hours without loosing 1 percent. still, really really really really satisfied with the note2's battery.
[Galaxy Note II General] KLUVJ:
not as good this time :o
[Galaxy Note II General] plotinus:
Mmm this seems so impossible! I'm not getting ever near your battery life! What tweaks have you done?
[Galaxy Note II General] KLUVJ:
no tweaks just flashed omega. however note that this is only 15 hours lol, compared to people with 3 four days and still 6 hours screen on, id say its quite normal
[Galaxy Note II General] adytum:
This, also, you're probably doing a lot of reading, which is the most power efficient way of having the screen on. I also go past 10 hours whenever I read a lot on the phone.

Something is wrong with my note 2. I just bought it off eBay. I mean I have power save on, brightness is pretty close to minimum, Wi-Fi has been on and I've been just browsing and talking on Google talk. But this is too good to be true. How do I get this to reflect what the battery life actually is?
[Galaxy Note II General] kylec:
No that looks about right especially considering you have power save on and brightness down.

So no need to change anything because that seems normal
[Galaxy Note II General] craigels:
I don't understand why I can't get as much screen time as others I have sync off low brightness power saving on and I still don't get even 5 hours
[Galaxy Note II General] jujuburi:
That power saving option has no great impact on battery life imo. You must be using 3G/H+, that's why you get low screen on time.

Hello everyone.

As I have seen on your battery stats you are not using internet browser too much ? That's right ? Because in my stats I have about 50% of internet browser and I am getting about half the battery time that you all have. Is that normal? Or I got a faulty device ?
[Galaxy Note II General] lawtq:
Hi

I'm on the stock browser ALL the time but it doesn't show on the stats strangely enough, my usage 10 hours screen time! Beautiful! Up from 9 maybe due to using Wanams custom rom and the custom kernal on the development pages.

Is your brightness set to high constantly?
[Galaxy Note II General] hudjw1:
No. I have my brightness at the lowest scale.

And another strange problem after a full charge of my phone after a restart my battery stats erased automatically and they started again from the beginning. But my biggest problem is my stock browser usage that its all the time above 40 Percent.

* I am using wanna ROM too.

mugen always bring out an extended battery for phone hence the origional note had one and s3 and s2...all depends on whether you dont mind extra thickness on a phone.

i could see one being usefull if you away on a trip for example and not near a power source and at 7000 thats a big battery :)

as i said it for people that find 3100 not enough as sad as that is :D...its out end of the year from what i read.
