Well I'm getting 5 hours of screen time but my battery life doesn't reach a day :(

When i play online games like Arcane or TOS i get about 3 to 4 hours.

Battery usage

I wanted to ask you about battery life on the Note II.

I am planing to buy one if it has a good battery life.

Maybe you know how much hours/days I could expect with:

- max 2 h Screen time a day with 50% Brightness

- on a clean custom Rom with good kernel

- over 90% on 2G Mode, 10 % on 3G

- Flight Mode between 00 am till 06 am (over night)

- no BT, GPS

- really less apps

- only whatsapp, Contacts, 2 Email accounts and one weather app

I searched through many pages here, but I am not very clear how battery life is for my kind of use.
[Galaxy Note II General] adytum:
You should have no problem going two days, probably three regularly.
[Galaxy Note II General] SilentEYE:
Thank you.

But at the moment I got 2 Days with my 1750 mAh battery. I think changing the phone for reasons of battery life is not usefull here.
[Galaxy Note II General] adytum:
After reading your usage again, you'll probably get more like 4 days. Impossible to guess, but your usage is probably similar to the ones getting 4 days in this thread.

I don't know if it's worth changing for battery life only, but as far as I know, hardly any phone comes close to the note 2 in terms of battery performance.

Rom : omega v12

Kernel : omega

Used phone in the night for an hour and slept it was 87 precent in the night, moving when I woke up lost almost 20 percent... And this screen shot shows media server draining more than a screen on time of one hour! Before battery backup was very sexy on stock.. Thinking about changing back to stock. Any opinions?
[Galaxy Note II General] Kojisan:
Download Betterbatterystats from Xda to check what's causing this. Never had that problem before. Even with stock omega kernel I lose about 5% only overnight. I sleep for around 6 to 7 hours.
[Galaxy Note II General] BoBBBBBBBO:
Stock rom, rooted.

Stock kernel.

Android 4.1.1.

Normal use, I live in a place where there is always Wi-Fi connection available, so I'm not using 3G that much. I think is good!
[Galaxy Note II General] timus911:
Kernel variation

First defining normal usage as Whatsapp almost every 10 mins, Firefox, half an hour of gameplay, 6-7-8 hours of Deep Sleep, (also i.e. when i sleep off.)

However, I'd say these stats are relative.

These stats are on ROMOW ROM v7(Rock solid ROM!!)

Stock kernel: 1Day 10-15 Hours

Perseus: around 20-24 hours

Redpill: around 20-24 hours

Just installed uNEAK kernel, seems more optimized than the above two, more smooth and highly responsive.

Stock kernel+Stock ROM--One sleep session of 7 hours I noticed just 1% consumption of battery.

The same with Perseus and Redpill, atleast 5-10%

Uptill now, I'd say Stock kernel is the best for battery life.

BUT, I've never had my phone as responsive and zippy as with uNEAK. Will upload its stats soon.

[Galaxy Note II General] t72e:
Here is the amazing battery life which I got on my Note-II. I was very busy for past few days and could not use my phone much, so I switched it to 2G only mode, disabled Mobile Data, Wifi, GPS and Sync. Used phone only for 2-3 calls and around 30-40 mins of browsing each day. This is on stock XXDMB2 firmware.

I'm still less than half way through! :)

[Galaxy Note II General] odehhasan:
I don't know how you guys get these amazing battery life stats. I use the phone normally; facebook, whats app, line, browsing, calls, viber... Etc. My mobile data always on, sync always on, auto brightness with the slide down to the bottom, motion and gps always on. I'm on stock Android 4.1.1. And this is my battery life as seen in the pictures.

Please let me know if this is normal or there's something wrong. I tried reducing all the settings that causing battery drain previously but the difference wasn't encouraging at all.

I reckon my screen time on a full charge would be ~10 hours, give or take.

- Brightness set at 50%

- Sync is always on

- WiFi wherever possible, HSPA otherwise

- Black wallpaper

- Dark-themed WhatsApp (WhatsApp Plus HoLo) and Messaging App (chomp sms), etc.

With the latter 2 I noticed a significant improvement in battery life!

I'm on stock DMB3, phone has been unplugged for 24 hours.

- Around 30 minutes Bluetooth audio streaming.

- This is also with Screen Filter enabled at 85% to decrease the brightness a bit more, after setting the phone brightness to automatic and minimum.

I would have loved to hit the 8 hour mark though :/ Next charge cycle I will decrease the voltages a bit more.

battery calibration?

Do we need to calibrate the battery? is there even such a thing as calibration for our Note's battery? I've read somewhere from Google (the actual site not the search engine :P) that deleting the battery.bin (not sure on the exact file name) doesn't really help with calibrating the battery as what some apps are telling us. And also, it is bad for the battery (li-on) to be discharged up to 0%, rather, you should charge when the it already reached 10%. Is this true?

Hope someone can clarify this :)
[Galaxy Note II General] dannejanne:
No. Battery stats are wiped every time you pull the phone from the charger (if you charge it to like 85% or more). When you see your battery stats in settings are reset, stats have been wiped.

Other kind of battery calibration is totally unnecessary and doesn't do a thing (other than what the system does by itself when pulling the charger after every full charge).

And yes totally discharging lithium batteries ain't good. Do it too many times and its health will be worse. The longer it sits totally discharged the more damage it will take. Probably talking days here though. Lithium batteries want to be charged often and not necessarily fully charged. Charge it whenever you want, how much you want. Do not fully discharge it. At least not often.

[Galaxy Note II General] Rhino-2-Horny:
thats true i have always been told and even read in a few battery articles thats draining fully is very bad for the battery as it reduces its life and that 5-10% should be left before charging...

[Galaxy Note II General] jonatton:
AOSP Project ROM with Perseus kernel. Battery life is more or less the same as with Stock ROM (which is good).

Never turned WiFi off, on 80-100% brightness, and used flash as flashlight (which oddly didn't show up in the battery section for some reason). Background sync on with FB, Google, Stock Mail. None of the battery saving options on.
[Galaxy Note II General] RambJoe:
I've had my screen pretty dark but I still get worse battery with less screen on time. Like the screen would have the strong majority of battery usage, with even just an hour or two on time.

I have 21% battery left, 43% is screen, and screen has only been on for 2h 53...

Has BetterBatteryStats been playing up for anyone lately? The reference points are useless now.
[Galaxy Note II General] Kremata:
I also use AllianceRom but with Persus kernel and Nova. Great Rom, great battery life.Still 66% after 21hrs WOW!

Again, none of the battery saving crap, 80+ brightness, WiFi on almost always, Sync on with FB, Google, and Email, Bluetooth transfer, used S Pen a lot too (not sure if it's taxing on the battery, but I'd assume it marginally might be). And just hit the 7 hr mark - I couldn't bring it down to drain entirely last time, so got frustrated and charged at 4% :p I'm sure of getting at least another 25-30 minutes with that, so yeah.

Love this damn phone.
[Galaxy Note II General] B3311:
Dualcore ROM, Redpill kernel with 50 mV uv for each cpu frequency, no OC. Monochrome theme, black wallpaper, gmail and Fancy Widget syncing. 50% screen brightness, wifi more or less always on except for 6 hours sleep. I'm happy. Best I've had on 4.1.2 firmware.

How much screen on time did you get? I get 1,5 day out of it with normal use, with work 2 days, when free just 1 day (6-7hours screen on time)
[Galaxy Note II General] Kremata:
Well I didn't let it go down all the way (coz I had to make sure it was charged for my work day) but when I recharge I was at 38% and I had 4h26m of screen time.

This Note2 is new from 3 days ago so I can't really say much more.

Now I already changed to Adam kernel coz I like Boeffla sound so I will see later.
[Galaxy Note II General] RambJoe:
I have pretty good reception and GPS is always enabled. I can't really tell atm what is using my battery, as BBS is completely broken.

Atm I am on 10h45m with 56%, screen is 40% of that with 1h30m. The battery life isn't that bad but I just feel that is a very low screen on time. Maybe Subway Surf might have used a bit, but I don't see how that would increase the screens percentage. I don't think that is as bad as my battery life before though. I used NEAK kernel on Paranoid Android on the N7105 with conservative governor.

I will try a day without subway surf or anything.

One thing I noticed when I was using Lux Auto Brightness was when I took a screenshot, the screenshots turned out dark, which made me think it was applying an overlay instead of lowing the brightness?

Thanks.

edit: Oo conservative must not have stayed on after I flashed ROM.
[Galaxy Note II General] jonatton:
Well GPS drains battery very quickly despite what phone you use. So for 10 hours GPS has been on and still you've got 50%+ left, that's still good IMO.

Try it out without GPS for a day or so with some heavy use, and if you still don't get at least 5-6+ hours screen time, then it's probably something else.
[Galaxy Note II General] Kremata:
GPS doesn't use battery if you are not using it. You can leave GPS on at all time. GPS is only used when you are on map. It automatically shut itself off.
[Galaxy Note II General] jonatton:
I'd assume he was using it? Not sure though. Or perhaps some background app was requesting location? Either way it does get a good slice of your battery life when you're using it.

@RambJoe I'd check background apps etc., but that's still pretty damn low - perhaps your battery's faulty? :(

[Galaxy Note II General] Kremata:
If you tether on a laptop you'd better use USB tether or plug your phone somewhere. As you saw, tethering is a real battery killer.
