I can't believe the battery life on this phone!!! Completely amazed!!

I have nothing on over clocked or under volted. I am rooted running a custom ROM. Completely amazed
[AT&T Samsung Galaxy Note II] DJHile:
LOVING the battery life! That's the main reason I haven't flashed any ROMs yet. I'm afraid of the battery getting quirky like it did on my Atrix after flashing. I'm sure I'll take the dive sooner or later. Holding out for an official OTA for now but who knows how long that will take.
[AT&T Samsung Galaxy Note II] alexninjam2:
I'm a heavy user... I use the navigation (since I have to travel for work), I receive tons of emails from work, take a lot of calls since a lot of my reps call for questions, text all the time, have 4gLTE on and use all day... thats just my main stuff I use it for but I do play games (need for speed most wanted), watch YouTube videos, and listen music using Play Music....

Conclusion- AMAZING!!

Strange battery stats

When I do not use my Note II much I observe strange power usage pattern. Here is an example:

The phone shows that most of the energy was spent by Maps which I did not even start. I assume that Maps might be used as a service by other applications (like weather widget) to get current location from time to time. But the numbers do not quite add up. After about 29 hours from last charge, the battery is at 61% (which is obviously good). The screen ON time is just 1 hour 11 minutes. The Maps CPU time is 2 minutes (and stay awake is 16 minutes). Yet, the percentage of power consumed by screen is shown as 27% vs 40% for Maps. This makes no sense. GPS time (in Maps section) is displayed as 0 seconds, so it can't be GPS. Also, Android System power consumption numbers are as follows:

CPU Total - 4 minutes

CPU foreground - 1 minute 22 seconds

Stay awake - 8 minutes

This is close to Maps times (more CPU time, less awake time) and yet Android System consumed just 3% (vs 40% for Maps).

Has anyone else observed something similar?
[AT&T Samsung Galaxy Note II] Mad383Max:
Yes I have seen similar high usage on maps when it is in sleep mode for long periods of time. I have t4ied killing it a couple of times but really not off of it lont enough to say.
[AT&T Samsung Galaxy Note II] justquan2:
Top pic is day 1

2nd is day 2.

The battery is what I have been waiting for oem. I thought I would have to buy a spare yet again to make it through the day. Now I'm buying a spare to make it through a road trip(if I ever take another one). Almost reminiscent of the old blackberry days.

awesome battery life running with perseus kernel OC at 1.8 UC voltage 75. so happy with battery life on this beast!
[AT&T Samsung Galaxy Note II] skim32:
Here are my stats. I initially had a mediaserver battery drain problem and was a little freaked out. But after some research I found out that the GN2 doesn't like itunes encoded m4a files. I converted those to MP3 and i no longer had the mediaserver battery drain problem. While I am quite satisfied with my battery life, I am a little amazed at Kristoph's results. A full day and it looks like moderate usage and he/she still has 50% battery. Does it save battery to turn off WIFI and just leave on the LTE? I thought that WIFI uses less power than LTE. Also I am a littler concerned as to why Android OS seems to be taking the majority of my battery usage. It seems that most people have the screen as the number 1 consumer of battery power. Which makes sense. I wonder if an app is causing higher than usual battery drainage. I do have Android Lost installed and an app called Do Not Disturb Me. I wonder how much battery life that these apps use. I may retest my battery after uninstalling some of these apps.
[AT&T Samsung Galaxy Note II] Mad383Max:
Pos5 your screen on time. If you haven't used much screen time then other systems will end up with a higher percentage. My media player has been higher on a couple of occasios.

On a side note, what has eve4ybody been getting for 'awake' time. I have seen over 13 hours and am sure that wasn't my best. Best I could get with note 1 was 8 hours awake. Best screen time for note 1 was 6 hours.
[AT&T Samsung Galaxy Note II] skim32:
Here are the screenshots for my screen on time. My screen on time is like 2.5 hours. And the Andoid OS awake time is like 5.5 hours. Seems a little low to me since your seeing 13 hours awake time.
[AT&T Samsung Galaxy Note II] Mad383Max:
Here is screenie of the 13 hour awake time.

Need to get cpu spy to check if you are hitting deep sleep and to see what speeds you are running at. Also need some kind of battery monitor (I use better battery stats) that can giv3 you wakelok stats to see what is actually keeping your phone awake.
[AT&T Samsung Galaxy Note II] skim32:
Downloaded both apps to see what's using my battery. Only thing is better battery stats does not seem to be working properly. I get a message stating no reference set yet. Does this app require root?

Don't think it is quite optimized for JB yet but it does work. I had the widget act flaky a couple of times but just removed it and put it back on screen and it was reporting again.

[AT&T Samsung Galaxy Note II] Dr. Evo:
I must have a defective battery then. I can only get about 3.5 hours on my phone until I hit the 50% battery left mark. That's with no live wallpaper, auto-brightness, no real video watching, some downloading over WiFi, and mostly some gaming and listening to music.

I have let my battery completely die and then recharge it with the phone powered off. Right now my battery is at 81% with 8hrs and 47 mins on battery. It's showing that MEDIA SERVER is taking up the majority of battery power at 29%, followed by SCREEN (26%), ANDROID OS (14%), and other processes are single digit and under 10%. My screen-on time has only been a whopping 27 minutes!! How is everyone else getting these insane battery times with the things they claim they are doing??? Do I need to contact Best Buy and get a battery replacement using my warranty or something? Because I can't see what many things I could possibly be doing wrong to be getting such horrible battery life.
[AT&T Samsung Galaxy Note II] dnyc:
sounds about right to me, I found that when my phones on standby it drains battery really quick for no reason that i could find. actual usage though, the battery is fine. I suggest flashing jedi 3.1 rom. my standby time improved significantly. Its my first battery test on this rom and so far i lost 1% in 3 hours!!!
[AT&T Samsung Galaxy Note II] Mad383Max:
What is your awake time for that eight hours? How much time listening to music?
[AT&T Samsung Galaxy Note II] P1 Wookie:

[AT&T Samsung Galaxy Note II] Dr. Evo:
I can't remember. But I took my phone off the charger 56 minutes ago and the battery was 100%. The screen-on time has been 14 minutes and my battery is already down to 96%!

[AT&T Samsung Galaxy Note II] shadowninja23:
Can't believe the battery on this phone, it's crazy!
[AT&T Samsung Galaxy Note II] Dr. Evo:
Below I've posted the best battery time and screen-on time I've been able to get, to date. I still haven't seen the insane double digit screen-on times others have posted, but this is what I got from minimal usage over that 1.5 days almost. Does this appear to be "about right" to people who are generally savvy about this topic? I really want to make sure that either my battery or phone is in good shape. I should also add that my massive media server drain seems to have been alleviated. Before, I was easily having 24% or higher media server drain. Most times, it was actually draining more power than my screen. I tried a number of different solutions I found online, so I'm sure which one helped, but I'm glad it did.
[AT&T Samsung Galaxy Note II] yellowman82:
Theres something may be draining it but you should be able to get more screen on time. This was taken after I put it to charge and had airplane mode on thinking something was wrong with my phone not connecting to my router but it turned out I had to reset my router.
[AT&T Samsung Galaxy Note II] Dr. Evo:
There's no image attached to your post.

At any rate, I will try to reset my router (lord!) and see what happens. I literally have about FOUR different battery monitoring apps installed, including WatchDog, BetterBatteryPro, Battery Calibration, and Juice Defender Ultimate, and this is the best I can do. I'm not a pro when it comes to understanding all of the metrics and what I'm supposed to be looking for with all of these battery monitoring apps, so I can't do much. Thanks for the response.

[AT&T Samsung Galaxy Note II] Mad383Max:
One more post. This was purely lte. No wifi to see how it would hold up. The wifi was on at the end but was not connected to the router. (Not really sure how it got turned on but you can see I am on data in screen shots). From my usage style, can see no difference between running on data or wifi.
[AT&T Samsung Galaxy Note II] lude219:
+10hr of on-screen time with CPU underclock (and undervolt) to 1ghz.

For those who don't play games and use their phone for actual work, go with this route. There's no discern in speed at 1ghz vs 1.8ghz. :cool:

Running Cleanrom with Perseus stock settings.

Screen brightness 60% /Wifi 60% / Network data 40%

General use:

Tons of emails & texting

1.5 hr in phone calls

1 hr web browsing

30min Gnav

20 min Spen

Apps in sync:

Gmail / google stuff.

HD Widgets 2 hr update interval.

Apps in use:

Digital Flux live wallpaper 24/7

2.5 hr tunein Radio Pro.

1 hr Youtube

So basically 3 days of moderate use screen on time 2 hr a day
[AT&T Samsung Galaxy Note II] Garnerj013:
I think that the battery starts showing some random app using the most battery life is less of that app being a battery hog and more of the battery stays having a glitch in reporting battery usage somehow or another.

Oh yeah? I had the same problem with att locker. I disabled it just to be safe.
[AT&T Samsung Galaxy Note II] Garnerj013:
Well, it only shows the screen using a small amount of battery. That is obviously wrong. I think the battery stats are just getting a little jumbled somehow. Maybe the first update we get well fix it.

Great Battery so far

I just switched (yesterday) from an AT&T SGS3 to AT&T GN2 and I am loving it so far. My battery life is extremely better and I don't even worry about looking at the battery percentage. WIth my SGS3 I was constantly worried about battery life. I tried multiple roms and kernels and batteries and nothing seemed to help. The phone could have been defective but I was really interested in the GN2 and I'm glad I switched.

Here's some usage so far.

So far I have had about 100 Exchange emails, 100 GMail emails, several phone calls and the battery has been great.

I'm running CleanROM 3.0.1 with Perseus kernel.:good:
[AT&T Samsung Galaxy Note II] Dr. Evo:
Okay, I am finally a happy camper! I don't know what the hell was going on with my previous Note II and/or what I was doing wrong, but I wasn't enjoying these crazy ridiculous battery life stats, that others have been reporting. I reported my frustration to Best Buy—where I originally purchased my phone from—and without even suggesting it, I was offered a brand new phone. I'm not sure what I can be doing different. I am doing everything I wasn't doing with my old Note II... using live wallpapers, not really using many power saving features other than Juice Defender, not using Airplane Mode... the only major difference is I disabled all of the Google Maps apps. I was able to pull a total of 44 hours of battery life over the last two days, with a total of 5 hours of screen-on time. I'm not really in a position where I have to rely on using my phone, often, so I'm not sure if I'll ever see 10+ hours of screen-on time, but so far I am very happy with these results. :)
[AT&T Samsung Galaxy Note II] ViciousMo:
Has anyone noticed a decrease in battery performance since using HD/Beautiful Widgets?

Also, to all the people getting phenomenal battery life...how often are your e-mail/social networking apps syncing? I have mine set to 15-30 mins and I am not getting the same life as you guys. I'm on a de-bloated ROM, no location services enabled, dark/non-live wallpaper, and it's good battery life and I'm happy with it. Although, what I'm seeing on this thread blows my mind. So, there is something I am doing wrong.
[AT&T Samsung Galaxy Note II] GetPatriotized:
I barely get a day a half out of it. I've freezed/disabled most of my apps. It's pretty much debloated. Do you guys have Google Maps installed? I have it and use it sometimes.
[AT&T Samsung Galaxy Note II] KEVK:
I have my work email (Exchange) pushing email all day long, as well as GMail pushing email all day long. I don't use Facebook so I can't comment on that. Have you tried changing kernels too? Sometimes that can help.

Facebook – Every hour

Twitter – Every 15 minutes

I'm running stock 4.1.1. All of my location services are enabled except for Google Search. I use the brightest, most animated, graphic live wallpapers I can find. My lock screen has almost everything enabled (using static wallpaper) and I have the scrolling Facebook ticker going at the bottom. As I said, the only different thing I've done—besides getting a new phone—is disabling all of the Google Maps and location features, based on many suggestions from others who had battery issues. I'm not sure if that's making a difference or not. I don't really need Google Maps because I used a much superior free navigation system on my phone.
[AT&T Samsung Galaxy Note II] shadowninja23:
I uninstalled mine, along with Street View and Latitude, and decided to use Waze instead. Now I don't have to worry about wakelocks from Google Maps or anything, and thus have better battery life.

I also removed or disabled a lot of the AT&T/Samsung bloatware and background programs that I won't/will never use. Are you still on CleanROM 2.1? Why not try 3.0.1?

You might also want to try a new battery. I was going to do this on my SGS3 before I switched to the GN2.
[AT&T Samsung Galaxy Note II] ViciousMo:
AT&T /samsung bloatware is already disabled. 3.0.1 is just multi-view, won't really affect battery life. My battery is 3 weeks old, my battery should be fine .
[AT&T Samsung Galaxy Note II] KEVK:
Ah you're right about the bloatware. Been flashing my SGS3 like crazy so I forget what is/isn't installed with the ROMs. Sorry for the confusion.
[AT&T Samsung Galaxy Note II] ViciousMo:
To add on top of it. I've downloaded autostarts and disabled non-essential programs from starting upon bootup
[AT&T Samsung Galaxy Note II] KEVK:
Sorry if I missed it in a previous post, but did you post a screen shot of your battery stats/usage? I'm using GSam Battery Monitor [ Play Store Link ] and it does a great job breaking down usage.
[AT&T Samsung Galaxy Note II] UserNamer:
On battery for 1 day 12 hours, currently with 12% left.

Screen was on 6h 19m

Voice calls were 3h 25m

Haven't been running BetterBatteryStats or I'd give the application usage breakdown, but:

1. "Screen on" time was reading a complete ebook using Aldiko with "Nighttime settings" (black background) and what I would consider minimal web browsing, a heavy amount of of texting and emailing, using Flipboard for roughly 30 minutes, and having Waze open for probably around 30 minutes of driving (with some Google Nav and Google Maps for other things in there, too).

2. Most of the voice calls were using a Bluetooth speakerphone.

3. I turn off Bluetooth and GPS when not using them.

4. I disabled about 30+ bits of bloatware.

5. I *just* got the MicroCell you see referenced in the one screenshot. It's been running for several hours, but otherwise I don't usually get great signal at the house.

6. Under the "Power Saving" menu, I have "CPU", "Screen" and "Haptic feedback" enabled, but the "Background color in internet" is *disabled*

7. I have 2 POP3 accounts which poll every 15 minutes between 7am and midnight and every 4 hours between midnight and 7am. I do not sync anything else.

8. I leave WiFi off unless I am downloading huge files, in which case I selectively enable it. (I have found, anecdotally, that WiFi drains my battery much more quickly than having a poor AT&T signal.)

I think that covers everything. I absolutely love the Note 2 and am constantly amazed at how much usage I get out of a single battery charge.
