[q] big battery problem please help!!!!

No matter which ROM i choose wether its 2.3 based or 4.0 based, Calks or Phantom. Even CM9, Team Dirt. I always get crap battery life. ANDROID OS and ANDROID SYSTEM hog the battery!!! Why is this. The only thing that has not changed will i have been flashing all these roms is the Modem. I am currrently running FF18 Modem. Could this be the culprit? Please help guys!

The android os usage in ICS is normal. What do you consider bad battery life?
So many things affect battery life. Low signal will wipe out a battery in no time, synching multiple accounts (email, facebook is notoriously bad...) and software you may have installed. How is the battery drain when the phone is sleeping? Since there really isn't much we can do about battery while you're actually using the phone, the next step is to improve on sleep efficiency and this will help the battery life overall.
Try installing BetterBatteryStats. There is a thread here on XDA you can search for and download and install this app. The best way to use it is to let the phone sleep on battery without using it for a minimum of 2-3 hours, overnight is best. Then view the kernel and partial wakelocks to see if something isn't allowing the phone to sleep properly.

battery battery life?
Couldn't you also use multiple profiles in an OC app to undervolt and underclock the phone when it sleeps? (screen off profile set to 800MHz and screen on 1200MHz) Just a suggestion, hope this helps.
I have to charge my phone twice a day because I am on it all the time. My ave battery life 11hr 47min. Running Badass Battery Monitor.

Turn off auto sync for your Google account on your phone and manually sync it from time to time. Before I did this android was at the top of the list in the battery. Now screen time dominates everything else in usage.

Yes I did this too, it helps a lot

Yes, synching too often is a killer.
Don't forget about the phone radio too: wifi/bluetooth/gps/data/4G all can have a negative impact if left running.
Someone recently posted that at his workplace, he had zero signal and he could barely make it through the day. He discovered turning data off entirely in that scenario saved battery in a huge way.

I guess you should try downloading any battery calibration app from the market and also try battery control.... I hope it would help you..... Or the usual juice defender :thumbup:

My Battery Life Setup

So, I know whenever I see people with awesome battery life pictures I want to know exactly what demon magic they're using to get it. Well, here's my demon magic for getting 36+ hours even with 3 hours of screen time:
FreeGS3 JB 1.0
Install the battery saver mod or use ktoonsez' kernel on ktoonservative governor (thanks Lolanerd); this one is key!
Frozen Apps:
Email
Exchange Services
Face Unlock
Favorite Apps
Favorite Contacts
Google Play Movies & TV
Help
More Services
News Daemon(EUR)
S Voice
Samsung Backup Provider
Samsung Browser SyncAdapter
Samsung Cloud Data Relay
Samsung Contact SyncAdapter
Samsung Keyboard
Samsung Push Service
Samsung SMemo SyncAdapter
Simple Alarm Clock
Sprint Connections Optimizer
Stock Daemon
That's it! This nets me awesome battery life even with autosync on and battery draining crap like Facebook installed. Just remember, if you don't have FreeGS3 installed already you'll have to give it at least 3 days (preferably a week) before you start getting consistently long battery life. Same goes for the kernel. Also, I'm not positive which of the frozen apps specifically affect battery life; this is just my setup. Oh, and this is all with power saver OFF! I should also probably note that the battery life is going to vary depending on how you use your phone; however, comparing the battery life I'm getting now to the same type of usage before it's still a HUGE improvement.
I assume you guys are going to want screenshots, but unfortunately I don't have any right now; I wont charge my phone tonight and I'll post a screenshot later tomorrow.

I thought it was common consensus that that battery mod does more harm than good.

Yeah it'd be much better to just get a custom kernel like Agats or ktoonsez's, then use a governor with hotplugging

I haven't had too much luck with agat, at least not with the jb version. The clock speeds don't stick which is really annoying. Is ktoonsez' kernel any better?

Yes, ktoonsez's kernel is my personal favorite, and you have to try out the ktoonservative kernel,its seriously awesome

I'll give it a shot, as long as it has hotplug support it can't be any worse. I'll update the first post with the recommendation

Reccomendations for a good battery saving app

I have noticed there are so many battery saving apps on the Playstore but do you have any reccomendations for a good one
Sent from my GT-N7105T using xda premium

Just install greenify. I have tried plenty before I had Note II, they've had little effect and I often had issues with many of them. If needed use power saving mode + greenify. Why, are you getting crappy battery life?

If your rooted install Redpill Kernel no need of any apps ,
Again for Greenify you need root but this is also suggested app ,
If your not rooted , You could try Juice Defender Ultimate from Playstore.

I'm not actually the battery life on the Note II is very good probably one of the best out there on a mobile phone, was just enquiring

Yes just use greenify and maybe fast dormancy toggle for disable it. It was the 2 best thing for a rooted device i done.

All these apps are a bit useless to be honest. The most important thing is just to set your brightness manually, enable/disable all the functionalities like GPS/W-FI/BlueTooth etc only when needed. Also setting your mail-account to sync once in the 2/3 hours, instead of 15 minutes helps alot also. If you are rooted, you could also remove some Samsung/Android Apps that basically do nothing apart from using battery.
A app to close the processes of application will help also. But if you want to try a battery-save app. JuiceDefender Ultimite for Rooted Users, GreenPower Premium for non-rooters.

Greenify.
You won't need anything else.

What does juice defender except turning off the data when screen is off ? If it's only that you can also do it manually.
Greenify is useful for lot of user and app which use data or process even if you disable synchro like facebook.

i installed greenify the other day and hibernate fb. but it was draining my battery when the phone was supposed to be sleeping. i then removed it and its back to normal.

I was so lazy to say this. Good thing. Thanks!

Well another point of these Battery-Saving apps. They could make your phone unstable. You can set manually the sync times for Facebook, E-mail , Weather Apps etc. Greenify works pretty good. It is basically a program to put the processes on the background on hold. When you use that application , it restores fast the proces (where it was). Handy for FB etc yes. Although sometimes you can see a small delay (hick-up) when you open a app that was Greenified.

If i have 2g on, i barely lose battery when the phone is in deep sleep. when i leave the phone at nite and wake up in the morning i lose like 1% or 2% max. but with greenify every time i was leaving the phone in deep sleep, i was losing like 2% per hour.

i will try uninstall greenify

Ok looks like Greenify will only work with rooted phones so looks like I cannot use it

Greenifying seeder or let seeder Run ?

As im installing seeder and also Greenifying many battery hog apps, the thought ran across ..do I actually wanna greenify seeder, or should it be left to run .
Would hibernating it affect it on wakelock, Obviously you don't wana have to restart seeder every time you want to use it... but id like to just have it run when the device is being used.
So if I greenify it will that be ok or render that app useless?
Sent from my SGH-M919 using xda app-developers app

First run Better Battery Stats and see if it's actually an issue. No point in greenifying it if it's not causing many wakelocks.

Im not sure what im looking at in better batt stats or what it all means ..
All I know is this is my 3rd s4
And the only one of the 3 that has stupid bad battery life... my last two were stellar.
Its so bad its comparable to galaxy s2 batt life.
Should I unroot and odin stock??
Or get a new battery the phones only 2 days old.
I watch the percentage drain like a percent every 3 min.

48hrs later.......

And I am pretty disappointed in the battery life of this thing. I used a htc one for a few months and I actually think it did better than this beast. I got to say though, the display on this thing kills everything I have ever used as far as the enjoyment from the massive size. But when I was looking into this thing I kept hearing 2 days easy with this guy. I am at 23% at 250pm when I took it off at 630am. Is there something I have set wrong or is this typical. My htc would be at 25-30% when I went to bed at night usually. I do have automatic brightness checked just an fyi because that is the first thing people will prob ask.

I can't comment on the original battery because I ordered a 7960mah battery off ebay the same day I bought my Note 2. I take off at 6:30 am also but my battery is at 73% and it's 3:28 pm. I knew I was going to abuse my battery so I replaced it before it even had a chance to let me down lol. Also, I'm running Paranoid Android 3.96 (Android 4.3) which is one of the custom roms that gets good battery life.
Wish I could be of more assistance?? Well here you go.
1) Disable daydream in your display settings
2) Flash a custom kernel for stock roms...I would suggest Saber or Perseus
3) Download STweaks after installing a custom kernel and perhaps underclock your processor to 1.2 Ghz, you shouldn't see a big difference in performance but should get a HUGE savings on battery life.
3.5) You can also allow your device to go into a deep sleep at 200Mhz while you're not using it. It's kind of like having your phone completely off but will instantly wake when you get an email, txt, etc. And afterwards after a user set time, it will sleep again until either you wake it or get another message.
4) Last but not least, if you really want to tweak your stock rom into tip top shape and aren't comfortable flashing alot of mods...download Pimp My Rom from the Play Store and let this app do the work for you.
Hopefully some of this will help you out.
**If you one day get familiar with flashing custom roms, this will be a huge savings on battery. I would recommend 4.2 roms or 4.3 roms because they aren't bloated with alot of the Sprint/Samsung junk that is running in the background, ultimately killing your battery without you ever knowing it.**

Ok found allshare cast and toggled that off. Didnt see a daydream anywhere in the display settings

This is correct. Lol. Daydream is a 4.2.2 feature, you wouldn't see that in 4.1.2, my bad.

Make sure there is nothing trying to sync if you dont have a good signal. Go to settings 》data and restrict background data. Keep facebook and other things from syncing when you really don't need them to sync.

Sent from my Kraken using xda app-developers app

I can't really say if the kernel affects the battery life that much, unless your underclocking which am overoclocked and still get great battery life but as of the smoothness saber kernel is great for me. I cant remember the last time I restarted my phone because of slowing down or just somthing wierd everything is smooth and fast all the time. Plus voodoo sound is very nice. Alot of users recomend the perseus kernel also but I personally had some random issues with it so saber is my daily driver kernel

You fail to show your screen on time. You probably have like 3hrs worth and at 55% for all we know. Which is what I actually get from this bad boy before I hit the 50% mark. On a good day I can get 6.5hrs of screen on time and I have lots of stuff syncing in the background.. 3 email accounts, Google services, Weather, Facebook, Samsung account, Skype, Tango, Twitter, ubersync, Voxer, what's app, YouMail and fring.
By the way did you get a brand new note or did you buy a used one? Battery could be faulty or another thing could be you are in a bad coverage area which drains batt.
