Is my battery life normal? - Galaxy Note II Q&A, Help & Troubleshooting

Hi All I just got the Galaxy Note 2 like a month ago and I've been loving it the only thing that I've been question mean if the battery life right now I'm getting like 4 hours of screen time and that's basically what I use to get with my Galaxy Nexus.
I just wonder if this is normal because I hear people a lot saying that they get several days of battery in for me I just feel like I have to charge it every day I also been monitoring the apps that I have and the background usage of them and nothing seems to be draining it.
I'm using android HD 6.0 with Perseus kernel
posting a screenshot right now..

On really heavy use, that is pretty normal. But for normal use or moderate ones, certainly not. Based on your screenshots, you have a lot of wakelocks, these are the number 1 culprits for unexpected battery drain, go get better battery stats and use the phone exactly as how you used it when you took those screenshots, then after a day or two, checkout better battery stats and find which app was actually causing those wakelocks.

I don't worry about battery life, brightness all the way up, sync on, widgets on every screen, Wi-Fi always on. I usually get about 14 hours

I'm very conservative. WiFi off, data off when not using it, brightness depends, auto sync off, no battery sucking apps like facebook

I get phenomenal battery life out of my S3 (stock).
I had an Epic 4G and was afraid to leave my desk because of the battery drain. With moderate usage (30-60 mins talk time, texting, chat, some web, exchange, ect) I can easily get 16-20 hours. Signal quality in your area will impact it more than anything. Also, wifi is vastly easier on the battery.
PS Facebook app SUCKS. Just bookmark the webpage and use that. Works better and doesn't ruin your phone.
Here how it looks like ! Lovin this screen on time..

I think it depends on how its configured. I've seen it eat the battery but also not use it much at all. Been a bit since I messed with it though so don't remember what settings made the difference.

i have betterbatterystats too but have no idea what the wakelocks affect and how to get rid of them.
Post a screen shot and I'll tell ya what could be happening.
You can improve battery life by switching to custom roms with less bloatware, and updating to more efficient kernels. (This is on a Rom/Kernel level)
Software wise, just figure out what apps are causing wake times and try not to use them. Basically whenever an app/widget refreshes/updates content, it may cause phone to wake (like weather/clock widgets for example).
I have been using cpusleep and it seems to have helped my battery life ... also using a custom rom without the bloatware is key for me.
my current setup is freegs3 release 6 with the latest trinity kernel...even though its overclocked my battery has been amazing and phone has worked flawless.
Im also using system tuner which has given me the ability to manage the cpu with on demand and other customizable settings
The only thing I synch is my k9 mail account
I also have frozen several samsung apps which helped...
Im now getting over 20 hours of basic use between charges...I dont use games/videos so might be a little skewed . I use this phone for business calls/internet/messaging/photos/navi...pretty basic
4500mah stock
Only 58% of battery
Sent from my SGH-T999 using xda premium
I have been using Gigajoule lately by feckmu and it has given me the best battery life out of all the custom roms I have tried. Even with GPS, WIFI, and screen at full brightness I can make it through the entire day with 30-40% battery left. If your looking for a rom-based solution to your battery life, check it out!

Extreme battery drain

I can only use my phone for around 5hours on time until she dies. This is super annoying because of school it dies before lunch :/. Have flashed many different ROMs, tried different radios, one or two ROMs seemed to fix this but don't remember which ones did . Phone dies 1% every 3 minutes it feels, this is retarded is there any known issues with that or fixes? Sticking with juice defender till I find a better option

do you leave your mobile data on?
also what is your cpu settings?
what rom and kernel you running
and take screenshot of battery usage page and post please
I always leave data on, yes. ROM: Jedi jelly 4, I believe that its insecure kernel because idk any other tw jb kernels. Also on the lb7 blaze radio but I constantly switch those up when I get frustrated with battery. Screenshot may not be accurate because I just flashed at like 430 today, so battery was at like 78% ish on last charge which was around an hour and a half ago. CPU settings are untouched atm

Bad battery maybe?
Sent from my SGH-T989 using xda app-developers app
Read my reply to the post here. It's an optional and known way of saving battery life for almost any Android phone and help prevent any overheating that you may experience with the phone.
Is your GPS on all the time? Account sync? Settings and data backup? Auto brightness or manual?
Always let the phone drain to 10% or less then fully charge it uninterruped, meaning dont unplug it.
CPU management always helps, especially with screen off. Also use wifi instead of data if avail at school or anywhere else for that matter

I'm betting its the battery. Place it on a flat surface. If it doesn't lay flat and it has a bulge that causes it to bounce around, your batteries screwed.

Got gsam, have ran it for a day. 100% at 6:00 am, 31% at 3:57 pm. This normal ? I flashed back to stock koodo everything , so is this just the quality of the phone? Yes, GPS is always on. Data is normally left on, although I do turn off WiFi from time to time. I used to have a nexus s and the battery would last for days, yet it's smaller and I never had to turn off things. I even get battery drain like this on cm based ROMs ?!

I went from Jedi Knight 6 to Jedi Jelly 4 two days ago and the Rom is super fast and snappy. Very little lag and no issues with fc so far. I do have a little bit of a battery issue myself. When I use the phone for anything I can sit there for an hour and watch the phone dip to below 80% after a full charge. It seems to eat battery when in use but overnight I get almost 14 hours of left untouched. I would like to get at least 8 hours with medium to heavy use. Is that a reasonable number? I have gone through three battery cycles so far.

Actually we are already discussing battery drain in this thread, so the previous poster did exactly what he should have. We don't want multiple threads for one topic.
Regarding your stats.. That's not too bad, but it's hard to say without seeing screen time, app usage, etc.

For anyone requesting input on battery life, please post screenshots of your battery screens as well as screen time. Also post a screenshot of the app sucker list in GSam battery monitor. It's impossible to say what's going on without seeing anything that's using your battery.

Does the DMA6 update resolve battery drain issue for you?

Hello All,
I just received the DMA6 update from Samsung... I know this update is new but it would be good if all of you can post your comments on the battery drain after this update.. Feel free to post screenshots of the battery..

Since flashing my battery life and deep sleep battery life is greatly improved. Very pleased with this update.
Thanks for your reply.. I just installed the update and am a bit skeptical and feel as if the battery is draining faster when the screen is on.. Might be that when the phone is in idle or deep idle the battery would be dropping less significantly.. let us wait for other users to post their comments... hope fr the best...

I had no batt issues since upgrading to 4.1.2
with this new update battery life seems better. Left my phone at 10% before i slept and woke up to it still at 10% so deep sleep is really good
Thanks Paulito.. As i said i am suspecting that deep sleep is good now... but do you notice a faster drain when screen is on.. Do let us know.. I will also keep an eye on the battery stats for the coming weeks and keep all posted.. :beer:

Guys, install Batter Monitor Widget and do a real test to see what your standby and screen on consumption is in %/hour. We need real numbers, not anecdotes.
With DLL7 I get between 0.6 and 2%/hour drain in standby. Screen on averages 10-18%/hour. Gaming is usually 30%/hour. Wifi on, brightness on auto, location on, Facebook , google plus, tapatalk and 2 gmail accounts syncing with notifications.
I'd love to see what this new firmware gets under those conditions .
I can't wait until it's available for my variant. On DLL3 my battery was terrible! I went back to 4.1.1 where I can easily go all day with 70% of my battery remaining.
I shall install the battery monitor widget and will upload my findings in a couple of days..

CPU runs at minimum speed <200Mhz is deep sleep
you need application (like better battery stats) to check it.

Nothing required to enable it,
it should go to deep sleep, if it doesn't go to deep sleep then you have to find out which process stoping it to do so.

Oops wrong forum
My battery is bad too but not as bad as yours even after I delete a whole bunch of apps I don't use ,turn off LTE (my area don't have it yet),
turn off Location scan in google map (betterbatterystats showing it checking my location every 2-5 minutes). Lets see how today goes.
Battery life has been amazing for me! I'm averaging about 13 hours of of juice from 4.5 hours of screen, in other words very heavy usage. I've been showing off to all the iPhone users at work, They now want a GS4.
I knew it. I freaking knew it was going to happen. Some arse buys a quad core "super" smartphone and then starts a thread crying about battery life. really? REALLY?!
well that's okay, i suppose. you can always post on XDA and beg for a dev to cook a kernel just for you that will miraculously give amazing battery life to your quad core super phone.
okay.... rant over. now time for a more tactful response.
IT'S A QUAD CORE SNAPDRAGON. i wouldn't get too bent out of shape on battery life. And I most certainly would not compare it to another device short of the HTC One.
Battery life is great for me. I only disabled some apps, kept most of the Samsung apps, but also disable all those Air/Smart gestures. I can go 2 days without charging with moderate use.
My battery has been alright, but I don't know why "google services" is showing such a high battery usage. I had the screen off for the last hour and google services is showing a 43 percent battery usage. That seems unusually high, no?
I did some investigating with "gsam battery monitor" and it showed that "networklocationlocator" has been causing wakelocks.

Android OS at 11% should I be worried?

Hey guys
I got my nexus 7 on Christmas day and as you can see in the screenshot its battery life is pretty good
I would have thought that the android os would go down from 11% to about 4-5% but it hasn't, I'm only on my 3rd charge cycle
What do you guys think ?

No.
With your tablet being on for so long (great battery life btw), it was doing literally nothing other than idling. If you were to use it a lot, playing games, reading stuff, etc., it would be down much lower. Don't worry about it.

That's exactly why I got a Nexus - because I knew it would be easy to root and mod, with tons of ROM choices, haha! But I think I get your point - they are great out of the box without a bunch of bloatware. Just got mine and haven't really kept tabs on battery usage yet, but it has been impressive, both stock and on CM11.
