[Q] CM7 and new battery

Hi all,
Few days ago i've received a new battery for my nexus.
I'm not sure now it was a good idea, but i've reset battery stats (by recovery) and proceed to a bump charge, then reset stats again.
I've done it twice because the first time, charge process jump from 55% to 22% and was stuck at this value. (bump charge and reset)
Now, my battery life is quite good (around 20 hours) but battery indicator is crazy.
Just after being unpluged, its drains quickly to 27%, stuck at this value for a while, then drains again to 2% and do the same.
What can be done ?
Wipe and reinstall cm ?
Thanks !

wrong thread to post to mate...
but anyways try reinstalling ROM and using battery calibrator to calibrate battery if your new battery allows it...

Froyo by Laszlo

Is it me or when I charge my G1, it only takes only an hour to get full battery. And it dies in like 2 or 3 hours later? Btw, I'm using an extended battery.

probably need a new battery, is this something new when you flashed froyobylaszlo?

FBL trashing battery
I`m having the same experience.
I started with stock ROM and than used CM4, CM5, briefly CM6 and ended up with FBL 5.2
With all CM mods, charging my (stock) battery was always a pain - it took up to 5-6 hours to charge it from 5% to 100%.
After installing FBL and clearing battery stats it took under 2 hours to charge my G1 to full. I was amazed and really happy with overall FBL performance... until few months ago...
I noticed that battery endurance started to drop rapidly, and my G1 went from 3 days without charging few months ago (I'm not a heavy user + I use min brightness and 2g all the time) to 12 hours 1 month ago.
In its last days it was unable some times to sustain power when talking or watching videoclips and phone would then shut off (as if battery was pulled out, not software shutdown). Also charging time started to grow slowly again to 3-4 hours.
I bought new battery (extended capacity, 1600mAh) under a month ago and cleared stats and all. It charges to full under an hour and I`m afraid that FBL will trash it the same way it did with the previous one in half a year.
BTW. FBL creator - Laszlo - stopped developing for G1 after his battery mysteriously died.
Could it be that FBL Kernel somehow mistreats G1s battery?

No every few months you need to recalibrate your battery
Kill it...charge it fully (plus extra)...wipe battery stats....kill it

Exactly what happened to me. So, I switched to Ezgingerbread, my battery lasted longer than it did on FbL.

That's because when you install a new rom it deletes battery stats calibrating the battery
Heh I really like this rom

Need HELP with CM9.1 BaTTERY

Guys please help me!!!!
My battery DRAINS even if I don't use WIFI BLUETOOTH .... or something like.
It just drains ,I want another kernel like battery extender by libiSC but some that is compatible with CyanogenMod 9.1 (RC2):crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying:

Welcome to my world.......
Ever since i flashed nims kernel v2.2or so, my battery's been behaving weirdly: after a full charge, it goes down normally.. But when it reaches 80%, it starts dropping rapidly no matter what i do. A minute later, its 75% and it will stay there for a long time.... before dropping drastically again. at the end. i still use up my battery within 1h 30min or so with lite 3G usage... As you can see from the screenshots taken from Settings>Battery.. Another weird thing is that when i reboot my phone, the battery level increases... e.g. i was playing angry birds that day, batt. dropped from 84% to 66%. ( i played for around 5 min with 50% brightness). And when i rebooted, the batt. level went from 66% to 79%! Was very shocked.. I hope there is another battery efficient kernel for my phone. Im on unofficial CM9 beta 10 MaclawStudios. I have changed my battery and STILL no difference. I have trird to flash firekernel but my fone fails to boot... Pls help me..
...

Is my battery dies away?

I have a JB 4.1.2 rooted moded rom
after 2 weeks of using the new rom the battery started to act creazy, it shows 60%, and when i reboot it shows 30%, or the other way, sometimes when it is 30% the screen act like bad tv transmision and the phone turn off, when i reboot i find charge is still 30%
when it drops from fast and i charge it for 15 min. it jump to 70%, and so on
did wipe chach and delvik with no change, any comments¡
is this battery life time? sholud i replace it? what do you recommend as replacment?

I'm having exactly the same problem and I read on another post that have been reported that after a year of use, our batteries have a lot of problems. So I recently bought a new one (of course original).

so did all these problems disapeared after using the new battery?

Congrats.. Maybe ur battery pregnant.. replace new battery n check it out is the only solutions！

[Q] Battery draining too fast in CyanogenMod 10.2!

I flashed CM 10.2 last night, and it had about 80% battery. But in the morning found the phone's battery dead. Recharged it again, and found out that it was losing 10% of charge in 15 minutes on standby. This is the first time I had battery issues like that.
I was using HarshJelly (latest build) , over which I flashed Carbon ROM (Build 6). But the carbon ROM was stuck in a bootloop.
SO, I decided to flash the benevolent CM 10.2. But got the battery issues I just mentioned.
I checked that wifi was off and brightness was at minimum.
AFAIK, kernel might not be the problem as CM installs its own kernel, as told to me by the people here at xda.
Does somebody has a similar problem? How can I stop this?

You did factory reset and you wiped cache and dalvik cache? What was consuming your battery most? BTW CM10.2 is draining battery more than stock and CM10.1 I think.

Yes, the usual drill - factory reset, wipe cache and wipe dalvik. Each of the times I flashed a new ROM.

Discharge/full charge 3-4 times. It should make it more normal... In Battery settings, what is shown to drain most?

The top drainers are-
1. Android System - 21%
2. Android OS - 18%
3. Mediaserver - 16%
4. Apollo - 12% (listened to music for over an hour before last recharge, using headphones of course)

This is first chageing after installation? Probably Mediaserver scan something, after it is done it will not drain that much. Like I told, do 3-4 cycle of discharge/charge. After that you will have better picture about battery life.

I bought another battery and for my surprise I got the same performance. So I investigate and I installed a battery calibration. You must be root for use it. You must charge the phone all the night, and on the morning, you launch the application without unplug the phone to the charger. Once you did it, unplug it, and try!
You must do it after every ROM install.

As shut_down said, the battery pretty much figured itself out after a couple of discharge cycles. Right now, I charge it once every two days! :highfive:

I want to try this too...
It's charging until 100% and then use until 0% then charge again???
Or is charge until 100% then discharge a little and charge again until 100%??

Charge to 100%, discrarge to something about 0% (0-5%). And again charge to 100%.

there isn't such thing as battery calibration. 10.2 is a battery drainer, period

Offtopic: I remember Saint from MadTeam said that battery calibration didn't existed... And i agree with him...
Well i tried this (I discharged my phone completely) and after charging overnight, it feels good...
Still testing...
If i play n64 on my phone for 1h, then the screen time lasts around 2h30m...

fix battery drain issue:cyclops:

i guess you use greenify and hibernate some apps drain your battery
sorry for my bad english~
