Everytime I reboot my phone my battery drops a significant amount. I tried charging it in full, unplugging it, & doing it again & then wipe battery stats but its still the same. Anything else I could do?

There are different theories/methods for this. I charge to full, unplug, wipe battery stats, plug in and charge to full again, wipe stats then let it run down to about 15% and recharge and wipe one last time. People will say my way is crap but it seems to help. Also, just letting the battery run down and charging back up seem to condition the battery to your new setup. There are several little tweaks made by devs in pursuit of better battery life so it may read inaccurately at first. Let your battery settle in. I say in a day or two, you will see improvement

Dunno about the "best way", but this is a convenient way without having to boot into CWM.

My battery indicator never shows 100% when fully charged. Highest it ever gets to is 98% (when blue indicator light shows full charge). I tried calibrating the battery using "Battery Helper" from the Market, followed the instructions, but still no change. Anyone able to point out what the issue is or how to fix?

The battery doesn't charge to 100% to prolong its overall
lifespan.

You can wipe battery stats from a file, I just don't remember what it is. My question is if I want to switch to a new rom, can I backup and restore it and not have to calibrate my battery?

From my understanding, what youre saying is that you have a current rom now. And if you back that up, flash to a new rom, and then go back to the rom you backed up do you still have to calibrate?
I believe your battery stats are saved when you back up, so I doubt you do, but for best results calibrate it .. especially because your phone dies different every day because you use it differently, so once a month, even with the same rom wouldnt hurt to calibrate.
There is an app called "Battery Calibration" by Ne'Ma that does exactly that. Its free. You have phone plugged in charging and when phone gets to 100%, you press it and it wipes the stats from the file

Wipe battery stats from clockwork then recharge to max then turn on phone
Sent from my SPH-D700 using XDA Premium App
No, lets say I'm already calibrated. If you switch to a new rom, the stats are wiped, right? If that's so, couldn't "/data/system/batterystats.bin" be backup up before flashing a new rom, and restored after flashing it so you don't have to re calibrate the battery?
my battery drains fast and i dont know what to do.
ive installed juice defender and did everything else to limit the battery drain as much as possible.
one thing ive noticed is that my screens brightness is set to low, but on my battery stats it says Display 64%
and recently my system says 30%
i left my phone on the charger overnight. and it got unplugged from the charger, when i woke i looked at my stats and the display was at 64%
the phone signal bar was filled and it was bright yellow.
and my system said 34%
can anyone help me?
When you plug it into a wall charger, can you confirm its charging AC and not USB
How old is the battery? Have you checked all the software that are automatically sync ?
I think that you must dig deep on what's your battery being used and consider the age of the battery in there too

There are battery monitoring apps that you can find to monitor unusual activity.
Now your display is at 64% which is very peculiar.

Try System Panel, it's in the market. Best app I've found for monitoring battery consumption, especially when you need more details than the About Phone section under settings provides. It is a premium app, but cheaper than a new battery. Hope you find a solution quick! Battery problems are a pain.

Have you tried calibrating your battery? Charge to 100%, then boot into recovery and wipe battery stats (or you can use the Battery Calibration app). Let the phone discharge fully - don't plug it in until it dies - then charge back to 100% without breaks.
It could also be an issue with your usb cable or charger. Sprint can run a test on the battery to see if it is the problem. Try calibration first to rule that out, and never wipe battery stats unless you're fully charged.

try charging it while its turned off then repeat the steps plainjane said. i was in the same boat as you when i flashed the evolved rom, now my battery life is pretty good.
What I just did was downgrade my radio one. My battery has been so much better in life. I am at 7 hrs right now at 66%. I have been using 4g, texting, and sending emails. Currently running Decks 1.3, SZ 2.2.1 CFS Havs.

I lose 10% an hour (sometimes more) doing absolutely nothing with my phone. I check battery stats and like 98% is screen.
Question: how can that be possible if the screen isn't even on ?
I have tried everything. I'm running CM10 stable (which is supposed to be good for battery life)
10% an hour? This is a joke right? I have like no apps running. I even tried using apps that put the phone into DEEPSLEEP as soon as the phone/screen shuts off -- meaning every app is closed.
Nothing.
Any ideas? please help i love this phone but im going through 2 batteries a day and im not even using the phone that much.

Hi, this is a probably already answered. I am new with root and flashing rom. After i rooted my galaxy note 2 N7105 and using jedi x16 rom. Start to drain my battery fast. I already read many post about cpu governor and tweaks. I tried different governor but it has no help. Still my battery drain fast. Any suggestion why i encounter this battery drain? Sorry for my bad english.
Thanks!

My advice, better stay close to ROMS close to stock. Plus, turn off sync, google back up, motion if you don't use/need any of those features. And explore the settings, there are things that you can turn on/off to save your battery.
Thanks!another question. Is it true that i need to wait a couple of days to so that my noye 2 can adjust to the new rom? Because. I rooted and flash jedi x16 last thursday only.

Since it is recommended by the devs, yes.
Also try charging your phone til 100% then wait for a half an hour at least then unplug it, then go to recovery mode(CWM recovery) and under advance, wipe battery stats.
And you can try DisableService app from playstore, it can disable unnecessary services of any app. Less services running, less battery drain. Be careful though with what services you disable. Here's the link for the app https://play.google.com/store/apps/details?id=cn.wq.disableservice
Okay i will try that. Thanks! By the way i have 2 diffent battery. Do i need to charge 100% and go to recovey mode? I think this is a noob question. XD
Thanks for your reply sir.

Yes charge it until 100% and wait for it to charge a little more, at least half an hour. Cause sometimes 100% isn't really 100%, that's why this procedure is needed for the phone to know what's really a 100% charge. It's like a calibration. I think you can do it only on one battery since every battery is not exactly the same.

Are you using a white theme on your rom? Better change it to black or stock theme. White colors makes the pixel on your screen light up and drain battery.

Install battery calibration by nema from the play store. It will do the same job.

No offense but you know, I used to do all this battery stat wipe stuff. Calib...etc. Then I started seeing articles about battery crash and low burn in. On top of that I read increasingly more about how chain fire himself said wiping battery stats is placebo if you think it is healthy or has any positive effect ...I really wanted not to believe it. Lol but hey that was couple years or so ago. I Dont mess with the stats unless I'm testing my work.
