When is it best to change ur rom?

On full battery or still plugged on the charger.... I know if u change your rom on half or low battery it really screws up the battery...

I've never heard of such a thing. I've switched ROms many times while @ 30% or below. Regardless, I think it's best to be above 50% and on wireless.

Why would it screw up the battery? I've installed many roms on many occasions and my battery was not fully charged. I'm gettng excellent battery life on CM7 right now (yesterday/today's uptime is almost at 19 hours and still at 40% with moderate usage).
I have the stock battery, mind you.

It really doesn't matter at all, just don't do it with 5-10%, don't want the battery dying while you are in the middle of a flash.

When u recharge the phone when recalibrate does it have to be off or on

This is all you need to worry about man. This goes for updating radios and recoveries through bootloader aswell. If your batt dies in the middle of something it could turn into a brick

Make sure that it's just charged enough that it wont die in the middle of a flash. You don't want that expensive of a paperweight. Other than that being said, i've flashed roms with under 40% battery before.

If you are talking about wiping battery stats, that really doesn't do much.

Battery Help

How well is the battery supposed to be while running the universe V1.4. All I get is about 5hrs with everything usually off. Is that normal. Should I get an extended battery? Can someone like me to one? Thanks.

While I cant speak for universe V1.4 that seems to be extremely poor battery life, i am currently on Blazer 4.1 GB, and with Wifi on, and moderate usage getting a whole day or more on a single charge.
have you wiped your batteries memory recently or just flashed the rom? it usually takes 4-5 full charges and discharges after a flash for the phone to re-learn the battery.
I would reset battery data in the recovery and then charge the phone to full and then fully discharge the battery, do this 4-5 times and see how your battery life is then.

Thanks but how am I supposed to reset my battery stats?
Edit:Nvm Got it.

besides going into recovery to wipe battery stats there is an app called battery calibatiion (market). does the same thing.

Battery life

Not sure what I am doing wrong but my battery life is horrendous. It's not the battery, I have three OEM batteries. Here is a screenshot from this morning:
I'm running Whitehawkx AOKP, build 8-16. Also have bad battery life on FreeGS3 with Trinity kernel. Not sure what I'm doing wrong. Any advice would be greatly appreciated.

I haven't tried that ROM, but using Stock Debloated or CM10 I easily get a full day of use. I listen to music while at work, read on the subway, and make about 2 hours of calls with about 40% left at the end of every day.

I don't think it's the ROM. I've been getting less than average battery life. Flashed a new theme last night and it definitely worsened. Even on FreeGS3 battery life was not up to par.

Jeez that is some really horrible battery life.
What you should do is a factory reset and flash the new wicked v2 rom with trinity kernel 43b. Make sure to wipe cache partition, dalvik and battery stats wipe.
Also after you do that odex your rom.
I am at 59 percent with 3hours of SCREEN ON time. This is with heavy use.

I'd prefer to keep AOKP as my dd. I know it's working well for people. I just don't know what's wrong with me.

Try to exchange the battery. If you got the phone at a physical store they should just give you a new one.

he already stated that he has THREE OEM BATTERIES.

i too has been having the same issue...even if my screen is on the dimmest setting on my battery stats, its still eating 60% or sometimes even more of my battery. ive tried different stock roms and made sure i factory reset/ wipe cache/battery stats and still no luck. any other suggestions?

battery calibration?

I did that a few flashes ago...maybe I'll try again.
Sent from my SGH-T999 using xda app-developers app

Battery calibration does nothing. Screen will always be the highest consumer of battery unless you don't use the screen and/or you're in an area with ****ty cell service. That's just how it is. The screens are power hungry. It doesn't mean there's a problem with your phone, that's how it is.

[Q] Weird Battery Issue!..

Hello all!
I got my GNote2 two days ago everything was fine until i've noticed that my battery level doesn't change for hours and hours. The battery level was 66 when i first look, and after hours in the and it was still 66 and the phone suddenly closed then i realised that battery drained. Does anybody have something like that before? And what is the problem's source? What is solution? What should i do to fix it? I'll add two pic to illuminate you about the exact situation.

Any idea comments?

Something must be defect. Regular unmodified Note 2? Then just send it for service/repair. Or even get it replaced.

Even I changed the stock rom to a custom one there is no difference and I've noticed that too when I pullout my battery and replace it shows the real battery rate but that is all.. Do you think is it battery or phone?

maybe because of your phone system board, better get a replacement phone.

I agree. More probable that it is a bad phone rather than a bad battery.

Guys before jumpong to the conclusion that the phone is bad why not see of some app is causing it
Simply install BetterBatteryStats and check the problem.
Also see if you have your phone rooted?
Have you applied any mod?
If problem still persists and is not solved then simple. Simply flash a newer firmware (ALJ3) from Odin and youre good to go

As i said before i have tried both stock and custom roms and there was no difference. Secondly i have just stock apps and casual normal apps i mean it couldn't be about an app. Actually there's no defect about phone's abilities just battery rate sticks what is was firstly when i replace battery. i wanna try with another battery to figure out is it about the battery or not but i don't have any chance for it.
Sent from my GT-N7100 using xda premium

Try to fully uncharge your phone, after when is dead put on charge. And wait until its full charged. Than reboot to recovery and make a full wipe (if u don't want to just do battery wipe) restart phone. Now check how it works aftery battery calibration.
If it will be same ****, change you phone true warranty. If you can't do that. You need to buy new original battery from samsung.com
Regards.

What would happen if i try my old SGS 1500mah battery on GNote2? I wanna see is it about just battery. Well it is kinda gift from abroad and it seems i have no warranty in my country or i'll have to pay it.

Bad news

[Q] kernel for best battery?

Hello all I was wondering if anyone had any suggestions on which kernel helps save the most battery. I am a high school student and by the time I get out at 2:15 my batter is at like 30 or 40 percent (even know I don't get that good of service and shouldn't be using my phone In school anyway lol) but im using the infamous 3.9.2 rom... Any suggestions would be great!
Sent from my SGH-T999 using xda premium

Well to be honest no kernel is gong to be the "best" is more like you need to be conscious what you have on. You have to give more info like what percentage you have brightness on, how often you have data on or gps. Also syncing takes battery away so having those on will take big chunks. Really battery shouldn't be that bad because technically I would guess your not using it as much in school.

I normally have the brightness the lowest it can go. I never have gps on.. I use juice defender to turn off my data when I'm in rooms that get no 4G and im assuming synching is off when my data is off to.

What's your typical usage - the screen on time ?
If it's average use and nothing is wrong, you might want to consider buying either an extra battery or an external battery to charge with. Or an extended battery. Battery battery battery.

use one of the several methods to find out what is using the battery...i use betterbatterystats then i find out whats waking my cpu and go from there...
after that i use titanium to freeze the problem...I do this for several phones and normally can get way better battery life from them

Just make sure you don't freeze something important that's going to cause problems. If it's a app you can always uninstall..I'd your screen time is about 4 to to 6 hours expect like 9 to 10 hours max of battery life. Extended battery will make the phone look bulkier and having a case is a issue. If anything get an external battery possibly with charger too.
