[Q] Battery life for Note 2 - Galaxy Note II Q&A, Help & Troubleshooting

This is a question for the new owners of the galaxy note 2. Have you noted the "screen-on" time for battery to go from fully charged to drop dead? One of the biggest problem with the Super AMOLED devices is the (relatively) abysmal battery life when web browsing as they do quite well when playing video. Let's say if you were to primarily browse the web on the device how much screen-on time would you get?

im on my 3rd day now without a charge with heavy use.

ummmm - wow...
Can you post a screenshot showing your battery life and screen-on time?

Yes please... that seems insanely good. Pics or it didn't happen!!

Sorry! I don't believe Note 2 can do like that. How about your heavy meaning?

On my original Note1, I got 4 hours max of screen-on time while browsing/facebooking.
Hopefully the note2 will be an improvement over that!

I got my Note 2 today, brand new and box-fresh. At 09:30 this morning I fired it up and it had 55% battery, so I logged into my Google account, did what you do with a new Android smartphone, downloaded a bunch of Apps, really put it under some heavy load, made a few calls, SMS, plenty of multi-tasking etc. At 15:30 it was showing 6% battery life including 2h50m of screen time.
For a fresh battery and heavy use, I think that's pretty good going.

My stats at this moment:

So about 6 hours of screen on time per full charge. Not bad, actually, its about a 50% improvement over the 4 hours of the note1.
I might still consider investing in an extra battery for those long days...

Moved To Q&A​
Please post questions in the Q&A section.​

thats odd as phone arena tried a battery test and found they would get around 9 hours continous video playback at full brightness and they say with half brightness they would come close to razor maxx at 14 hours screen time?
but still ill wait till others have tested it properly
http://www.phonearena.com/reviews/Samsung-Galaxy-Note-II-vs-Galaxy-Note_id3136/page/4

Video playback doesn't consume much battery on AMOLEDs, web browsing is more battery-consuming due to white backgrounds. Also, phone Arena said clearly that the phone was on airplane mode.

very good battery life... for almost 2 days (I used S3, S2 before and this is a very good phone)

The mains adaptor that comes as standard with the Note II has a 5 Volt 2 Amp output that should be good at charging the battery as many existing power supplies are 1 Amp or less.
If you plan on using a car adaptor, don't buy a cheap low current one - most are only 500mAh or 750mAh.

looks like battery looking good so far from you guys..i say give it a week of cycles. still needs braking in...does the back get really warm when charging? is charge time fast?

After few more cycles the battery life is just CRAZY
And I wasn't even using battery-saver mode !

Just found that:
Set to playing a video file at full screen, with Wi-Fi and 3G switched off (this is out standard test for tablet battery life) and screen brightness set to 50 per cent, the Samsung Galaxy Note 2 lasted for just under 12 hours.

Here is my Note II battery usage.
First day
Out of box without charging at all. Used it from around 49% to 3% for around 5 hours+ Screenshot attached.

Second day
The night before charged from 3% to 100% with my Note II power on for around 9 hours. Then unplugged and heavy using from 100% to 10%, it stayed more than 14 hours. I am saying this is pretty good juice. Screenshot attached.

How long are you guys putting this on the charger? Normally put my phone on charge when I go to bed and when I wake up it is fully charged. This phone was on the charger for 7.5 hours and went from 7%-63%. WTH????

Yesterday I charged it from 10% to 100% in about 2h30

That's probably what I'd get out of my NS if I used it fairly heavily... the display is a battery killer on that too. So about average, then.
Don't know what happened to the quality though,looked OK when I took them!
Hoping when this mobile data problem gets sorted battery life may increase as my phone was all over the place today!

Ouch, thats some serious drain. I was hoping for at least 18hrs. Still not a deal breaker for me.

2H 55 of screen time looks to be pretty lacking if I'm not mistaken?
The Galaxy S II video run downs get like 8H or 4H on web browsing.
But yea, diff situations
Your pictures are broken can't see any of them.
Edit: 3h screen on sounds pretty normal to me. Depends though on the brightness of the screen.

Those are completely different. They start with a full battery and just play videos or browse the web for that amount of time. With this he was using for the phone for random things and still had the screen on for 3 hours.
On that note, how is it possible to have the screen on for 3 hours of a 12-hour day? You literally spent 1/4 of your day looking at the screen? Do you not have a job? My phone sits in a dock on my desk, but I probably use it around 15 minutes per day while at work, and then another 45 min or so after work (so total screen time, if it wasn't sitting in the dock, would be around 1 hour for an 18 hour day).

Those run down tests are from 100 to 0 doing 1 thing. This is throughout the day. The phone is still draining when the screen is off.
yea i understand.....but basically the screen time is how long the screen has been on throughout the day correct?
I had a galaxy S and it used to get like 4-5 hrs of screen time throughout a 12hr day. With the extended battery i could get about 6-7hrs of screen time.
Now on the iPhone 4, i get 2hrs of screen time with 80% battery left and had a standby of 6hrs. But yea....its iOS
Idk, 3hrs of screen time seems ehh to me. Im still probably gonna get the phone though, tired of iOS once again. Went from 3GS to Galaxy S to iPhone 4 and now possibly Galaxy Nexus....or wait for GS III
Wifi radio power on all day?
Several people who've had the phone for a few days have said the battery life gets better after a few charging cycles.
Calibrate the device, leave it off then charge it till it's full. Then use it till it is dead, then charge it again while switched off and keep doing that for the first week when you buy a device any device that uses a battery. I've always done this to my phone and my wife's sometimes friends too. After that the battery is calibrated, then if something goes wrong with the drain you would know, or if the battery life actually sucked Case 'n point EVO 4G.
yea, 3 hours used 56% of the 85% of the battery that was used. so really should be able to get 5 to 6 hours of just screen on time.
I uninstalled my virus protection yesterday and turned off sync and wifi whilst at work today about 11am and battery stats better today. Haven't been in a low signal area today so no problems or slowdowns caused by 2g/3g.
Taken off charge about 9.30am
Wondering if its the virus protection taken off or disabling sync and Wi-Fi or the fact I was in 3g area all day that's improved it.

Signal strength is usually the main problem I have...
Is there a native ability in ICS to disable WiFi scanning? ie - Leave WiFi on, but disable scanning for networks...
OP, I'll bet your batt life would be 3x better with something like Tasker managing your Wi-Fi connection.
IMO, BEST.ANDROID. APP. EVER.

[Q] How many hours do you get before you charge your HOX?

I did not see a thread similar to this for HOX. People have been saying that HOX battery is not as good as SG3 but I just wanted to get an idea how much other users are getting.
MY HOX White is giving me an awsome backup for 48 hours average with 2 hours screen time and 45 minutes talk time. I think it is awesome. Post your hours here.
Not to bad almost 3 days before I had to put it on the charger 5 hours screen time. Running Charmeleon v5.0.0 with stock kernel.

Hey man;
Sure the battery life in SGS3 is better, it has lighter processor (which doesn't help in heavy gaming, very fast in normal use though), more energy efficient AMOLED screen (which has less quality, but better brightness), and also the simpler TouchWiz UI (which is a bit childish in my opinion, but does the job well)
I get about 8 hours with heavy gaming (near 1 hours continuously) and web surfing (actually downloading, almost 500MB in total) and something like 1 hour watching music videos...
I get 2 1/2 - 3 hours screen time max! In the battery drain test my battery reaches 84% by the end of the hour, which I thought was great, but then again that test requires you to put your phone in Airplane Mode. The screen is a battery-hog imo, but its beautiful even with the stuck pixel I have haha.
LEt us get some more people to answer this one before we reach any conclusion.
Results are inconsistent for sure. Few people like me are getting 2 days average and few 2 hours!
For me it depends on what is running.
Normally I get about 14 hours of moderate use with 2-3 hours screen time.
Today I'm at 10hrs with 1.25hours screen time and I'm down to 11%. But I believe it is due to having wifi and viber running.
Personally it's my wifi that is really killing the battery. But given how I use it, it is perfectly acceptable
Is it true that non-rooted HOXs have poorer battery stats as compared to those that are rooted? If so, why?
I'm not rooted and am on stock everything.
How exactly do I go about testing the battery on my HOX?
Any tips for better battery for non-rooted devices?
I get about normal usage ( 3G-1 hour, Tegra games- half our, Music- 2 hour, SMS and Calls) 10h, just SMS and Calls about 30h.
The number of hours i get varies from time to time . On normal usage including listening to music, messaging, playing games and talking on the phone i get approx 4-5 hours max.

How were you able to replace the battery icon with a number?
Its normally there in the tweaks of the rom ur using .

@Skywalker, I am all stock. How do I go about making the tweaks in the Rom?
Very frankly after receiving OTA 1.28 my battery lasts 2 days after every charge . some tips.
1. While you are listening to music keep the screen off as screen sucks up most of the charge.
2. I do not let my battery go below 15 %, I have read that letting them go below a particular level reduces the actual life.
3.Try these small steps, it resolved the issue of low battery life for me as I had read it somewhere:
> Turn Wifi and then 3G off
> Turn either Wifi or 3G on again
> Do not keep both "On" at the same time.
4. Kill the Maps process by going to the task manager ( If not using it all the time).

I think turning off the screen while on a call or when listening to music will also aid in less battery drain. No?

I charged it up during the day yesterday, but then hammered it syncing my emails, sms messages and other things.
So, last night was my first real charge. I took it off the charger at 6am this morning, and right now, at just a few minutes less than 5 hours, I'm at 83% with 70% use being cell standby.
I'm sticking with HSPA+ today, because I know that will drain the battery more than WiFi (at least that was the case on my Atrix) and I'm trying to get a feel for the battery life when away from WiFi.
Now, full disclosure, my phone has 6 email accounts setup for push. An Exchange account, two Gmail accounts and three Imap idle accounts using k9 mail. Still, I would say it's burning battery at a little higher rate than my Atrix with those same six push email accounts.
5 hours and down to 40%.
:-(
I'm seeing a significant increase in battery life whith the s3 over the s2

I'm a bit of a light user, but a little heavier than average given new phone.
7.5 hrs @ 57%.
I'll post screens when I can.
5 Hours, 45%, screen on 2 hr, 12 min.
Interesting thing: I have a Pandora Widget on my screen, have not used it at all, and 13% of my power, and show son for 22 min.
9.5 hrs @ 29%.
I am using the default juicedefender profile.
Cell standby hogs the battery more than other phones like US One X with same SoC. I think kernel devs can work on this since this is not normal.
To get a good idea on battery life, everyone needs to show their screen on time as it should be the biggest drain.

^^ I had power saving off for the first 3 hours of the day, and screen was set to 1/4 brightness. I changed screen to auto brightness, disabled wifi network scanning/notification, turned on power saving mode (all options), and it's been like that since about 3 hours into the day. I've done some driving with Slacker Radio streaming via bluetooth to my Jeep.
Seems like cellular standby eats juice. I am in an LTE area.
is the a way to turn off LTE?
This is mine so far, don't really run any battery saving appsetc. Cell standby is a bit too much.

It is for me because I use the thing everyday. My Transformer Infinity would last a couple of days on a charge because I never used it since there was so much lag. The G Pad is so good that I actually look forward to using it over my G2 whenever possible. That wasn't the case with my Infinity.

Same here! The best way I describe battery life is as follows:
Other tablets I've had: 99%, 73%, 49%, 31%, 11% Charge Battery
G Pad: 100%, 100%, 100%, 96%, 89%, 84%, 79%, 76%, 69%, 61%, 53%, 48%, 39%...etc etc etc : )

The new iPad mini comes with a even bigger battery that the old one, reason why it is slightly thicker and heavier.
I have all sorts of tablets, iPad last longest when it comes to browsing and standby, nexus 7 use is 2 days my lg g pad is one day, I find each has their selling point and sometimes I sacrifice battery for other things.
Battery life ok
It is off course difficult to say since consumption is very dependent on use.
In my case it is the screen that uses by far most power - around 70-80% I think.
I have light on auto and 50-100% on the slider and it generaly uses 10% pr hour of use.
When I don't use the tab and wifi is off it uses virtualy nothing and I think it would run for days
And how fast it charges...
Slow as hell, 4 to 5 hours from empty to full.

Charging Time line while sitting on my desk
9am - 5% start
9:30 - 20%
10am - 44%
11am - 75%
Looks like a full charge by 11:30am. So from 5-100% in 2.5 hours.
5 hours screen on for me for GPE
I just got it, first day I got 5 hours screen on time in 24 hour period and it was down to 10% when I charged it. Then it charged about 12% in 2 hours so I unplugged it and right back in and it started charging faster after that. Once charged it seems to go from 100%-90% fairly quickly then it levels out.
I'm not complaining about idle time...
I almost always use my tablets and phones with the brightness under 25 percent of maximum; that being said, I cruised through an entire weekend with the G Pad without searching for a charge, and that’s pretty impressive.

Screen on killing battery - 5% over 10 minutes!

I'm getting such bad battery drain when the screen is on its ridiculous. I've taken some screenshots from Gsam and as you can see at times I'm losing 5% battery over ten minutes of screen on time. I'm not gaming or doing anything cpu intensive and the screen brightness is set to 25%.. What sort of battery drain are others experiencing when the screen is on?

I am pretty disappointed. I had a Z2 then Z3. IMO you haven't experienced great battery life until you've used one of these phones. It's really unbelievable. I couldn't kill it in a day, period. It's really hard going backwards. I don't care how fast a battery charges or whether it's removable, there is simply no substitute for a phone you take off charge in the morning and run all day with zero thought to the battery until you plug it in at night. For me with the G4 battery is crazy bad with screen on and almost as appalling screen off. With the Z2 and 3 if I didn't use my phone much say during the morning at work it would have 90% left at lunch time. Or even streaming Pandora all day barely touched it. Same for this phone I'm already down to 70% without using it by lunch. In this reply I've lost 6% so far. I think all the comments talking about turning off WiFi, and lower brightness etc are all BS. To me, that's not using the phone. It's not making my day and my business easier if I'm constantly worried about battery life.
I've found that the avg screen time no matter what is 3-4 hours. I get 19hrs on my battery on avg and always get between 3-4 hrs of screen on time. Having that spare battery is a major help.
I miss my turbo for it had minimum 5hrs sot and over. Still getting used to this battery life on my g4
Mine has gotten better after a few cycles. The screen off drain is extremely low, which makes up for screen on drain in my case.
On my Z3v, I was amazed at screen on time - but the battery would just drain at 10%/hour pretty commonly - so even though i could get 5hrs of screen on - it would still only last for a day. With the G4, I use it all day when I need to, and then after two days I need to charge it. Not to mention I got 5hrs SOT yesterday.
I wonder if anyone will develop a 4k Mah battery that fits in roughly the same size back? I've seen 6k already... but I dont need that much. Just a bump more will help.

What do you count as a cycle? Mine is still crap after owning the phone for weeks.

Recharge cycles, letting it get low enough that It needs to shut down and then charging it back up with the stock charger.
Others have reported similar, and others have also mentioned doing a factory reset if you haven't tried that.
Overall I agree with the barely average life. Especially with this phone - I'd rather they make it .5mm thicker and put a bigger batter to allow for real all day phone use of calls, email, etc.
