Samsung Galaxy note 2 battery life - General Topics

After upgrading my note 2 from 4.3 to 4.4.2, my phone's battery life is suddenly downgraded.
before upgradation, DU BATTERY app shows battery run time for more than 26 hours, but afterwards suddenly shows 15-16 hours.
I gave my phone to service station but the problem is still unsolved.
So if there is any solution kindly post it.
Thanx

Android OS battery Drain on 6210

I don't know why this is happening... and I am doing quite a bit to try and alleviate it.
When I first got this tablet the battery was fantastic and it maybe used 2% over night when I slept. Now in one hour it can use 3% to 4%.
I have done the whole 9 yards of flashing back to stock, factory reset, all of that.
I sent this in recently to Samsung since I was having SOD issues and told them to fix this problem too but they fixed my SOD problem but not this one.
When in the battery use area in setting android is using any where between 12% and 40% of my battery with over 10 minutes of CPU time. When I first got this tablet android OS MIGHT have used 5% on a bad day.
I am saying this is the problem in terms of my battery but any input would be appreciated.
Edit:
Here is a screen cap of my battery usage (ignore that white line on the graph that was when I flashed LA3 back on to the Tab)

You may want to look at what is draining your battery under battery statistics. If nothing there is abnormal, it may be the battery. I was experiencing a similar issue with my GSII. It would be down to 80% in a matter of minutes. I tried underclocking my CPU and everything, then it dawned on me to check the actual battery, sure enough it was starting to bulge. I replaced it and over the weekend I went 21 hours without having to charge my phone once!

iNew V3 MTK MT6582 - Battery Issue

My iNew V3 Battery is insanely draining. Earlier it was working fine for 3 or 4 days, then suddenly it was not charging up to 100% and discharging rapidly in few minutes. I have tried to charge more than 3 hrs but no use. its going to 1% and switching off and showing more than 30 -70% when ever I keep charging in off mode.
Code:

I have checked with re-sellers support, they have suggested that firmware update will resolve battery issue. I have updated firmware from cxq_v3_v1.0.6T02 to cxq_v3_inew_v1.0.4. after updating firmware now mobile is charging to 100% but immediately with in 1 or 2 hours, some times in few minutes its going to below 4% and switching off. some times it will charge to 100% with in 30 min.
I have checked battery with multiple battery calibrate apps and find no issue, all are showing healthy and good status. There is no Physical change in appearance/size in battery (like expanding in size). its good as new one.

Face the same thing here. Rooted mine to freeze some of the bloats but Android System is still at 91% consuming my battery. HElP
From what i understood you need to wipe the phone when updating to firmware 1.0.4 - then this problem should be resolved.
my inew v3 is on the way so i cannot tell from personal experience,
but i read on a different forum that this seems to have fixed the problem.
also, check the other thread here about how to get a THL W8 battery working (2000mAh)

[Q] Battery problem

Hey guys I am a long time Android enthusiast. I have one of the most popular Samsung devices which is the Samsung Galaxy fit. The problem with my Samsung Galaxy Fit is the battery. Earlier before any tweaking battery used to be normal. After I installed CM7(official build). My battery started draining randomly. At first it was ignorable but then the problem became severe. From 100% it would drop to 88% in just 2 mins use and then from 88% it wud drop to 70% in another 5 mins and the entire phone would be dead in just 3 hours at best. When I would charge the phone again the battery will also be charged randomly going from 5% to 20% and then 20% to 40% all this in just 10 mins. In no less than 20 mins would my phone be 100% charged but that's fake as the battery would drain from 100% to 0% in three hours.
Following are the solutions are tried
Changed the batter,used a brand new original battery(FAIL - DID NOT WORK)
Flashed stock Rom (FAIL - PROBLEM STILL PERSISTS)
Changed Charger (FAIL)
Recharged battery on a different phone and then inserted the battery in fit (FAIL)
If anyone has any solution please let me know. I AM ALSO WILLING TO DONATE IF PROBLEM GETS SOLVED.

You could try Battery Calibrator.. The app is available on Play Store.

Hope this will help you..
1. after flashing custom ROMS, back to recovery or CWM then wipe the battery stats.
2. calibrate the battery while device is on, i ussually use Mugen Power app (install app, choose the standard battery, charge until 100% then click calibrate, after that use the device until the phone is dead then charge until 100% again while device is off).
other Calibration apps ussually have the same steps like the steps i mentioned above, so just use one app..
3. if you still having the battery drain, maybe you should go check the hardware in some technician, coz it could be the hardware that has the problems.
