Usually doing 2-3 charging cycles does the trick (fully deplete battery and then charge until full).

[Q] strange battery behavior

I have problems running CM7 ROMs on my device. When battery is about 50%, it suddenly runs empty. When rebooting battery life is still at 48%. I haven't found an answer to that problem by searching yet. Is there someone with same problem?

I wiped batzery stats from cwm, I calibratet battery through an app, didn't change anything...

OP you need a battery calibration:
First link on google http://forum.xda-developers.com/showthread.php?t=1616598
Googling "battery calibration android" and your O2X will tank you !

As I said, I loaded battery to 100% and wiped battery stats from CWM. But even right after the following boot I couldn't get the battery empty, because suddenly the battery stat ran down to 0, after reboot it was back to 38%.
I only have this problem with CM7-based ROMs. At the moment i'm using Modaco, battery works fine!

I flashed my device again:
- battery fully loaded
- full wipe
- wiped dalvk cache
- wiped battery stats
- flashed Gueste 3.6
Battery was at 100%. Last time I looked on the battery status it reached 26%. About 30 min later the phone was off. Turned it on again - 25% battery.
So calibration didn't help.
Any ideas....?

i did an experiment - changed my phones CPU minimum frequency to 300 mhz. it is one step from default value. now i'm testing third battery lifecycle without instantaneous battery discharging problem. You can try too

Ok, I will give it a try.
If it works I will not flush my phone in the toilet. Otherwise....

Semms to work, I changed the CPU-frequency and didn't have a shutdown yet.
Thank you for your help!!

Maybe you just need to replace your battery for a new one. Batteries don't last forever, some time ago I had to change my nb battery

If anyone else has this problem: it always occurred when I had bad network connection.
I changed Baseband and RIL from 218 to 725 (v10d), didn't have a shutdown yet.

Does my device needs battery calibration?

My device battery is draining very fast so i wanted to calibrate the battery. I downloaded battery monitor and i get 4300++ when its on 100%. So do i still need battery calibration. Im planning on trying zeppelinrox battery calibration.

Battery calibration is a myth.
Will do nothing other then wipe battery stats and make a new one.
It can be done by charging the phone till 100% and disconnect it from charger

Instal good battery monitor like gsam etc. You will be able to see what is draining your battery. Also do not use full brightness all the time.
P.S. What is fast for you? Can your battery stand a day?
Sent from my GT-I8190N using xda app-developers app

Its like when i leave my phone for about 2 hr. The battery drops from 70-50% on wifi. And i used to be able the last the whole day with 3g on and my phone is only 2 weeks old.

You're not alone bro. Same here!

well i agree with the battery saver is a myth statement... I see you have used battery very bad way and now battery has depleted its life span. So still battery is on good side... Just try to do one charge cycle and close all unwanted apps and processes/features so it will conserve battery that way you can keep your battery safe or if you are really unsatisfied try this http://www.mugenpoweronline.com/zas...tid=5&sortby=sortid&orderby=desc&type=carrier
Good luck!
Hit thanks if i helped :good:

yes, battery calibration is a myth, so you must try install a fresh rom (try light by somin, its very battery friendly), use your brightness always low, and your wifi always off when you dont need it. you will see that your battery (if its not broken) will last for at least 2 days (depending on your phone usage)

and the best "calibration" is to drain your device to 0% (it will shutdown) and then charge it to 100% without using during charging. Do this 2 or 3 times and your battery will be very well.
this http://www.mugenpoweronline.com/zaspx/product_details.aspx?file=pr&productno=1640&PageNo=4&ccatno=5&csubcatid=5&sortby=sortid&orderby=desc&type=carrier is bullsh**

If you're rooted you should also download DU Battery Saver PRO and tick the option "low cpu frwquency while screen off'. Just that little option changed my phone's whole life style It really does work so give it a try, you won't be dissapointed.
and yes battery calibration is a myth and doesn absolutely nothing which may help your battery life (i know from 1000s of personal experiances with the calibration thing )

[Q] Phone is always awake (battery drain overnight)

So I got my One two days ago and installed some apps, running on stock 4.1.2.
According to the system monitor my phone is ALWAYS AWAKE, even when I turn it off and only plug in the charger.
How can I solve it, how can I find what app is keeping my phone awake? I am losing like 50% battery overnight while in airplane mode
Thanks, BBLN.

It's difficoult found the app.
So try with an hard reset or see in dev settigs if there is the voice selected

Nope, it's like my phone is draining while being idle (On battery usage: Phone Idle - 50%).
I closed some running services, seems like now he is finally really idle.

Charging Problems

When I let my phone charge over night, once it reaches 100% it starts to go up and down in percentage. This started happening after root and some app freezes/ disable
Sent from my LG-P880 using xda app-developers app

It might be helpful to name the "some" apps you froze (the "disabled" should not matter). Apart from that: At the second half of your screenshot, the device was permanently connected to power? So it goes down as far as 94% while connected?

Yes that's when I left it on the charger throughout the night. And when you see the slight decrease near the 50% range is when I got a text.
Here are the apps I froze:

I have the same problem using jellybeer and iodak kernel v7 (but also had this problem using optimus prime)
Percentage drop is inconsistent, 92-93-96-98 %, depends on the days
Battery stat reference points are created on power unplug so it's hard to know what's draining battery...while on power, it's not easy to troubleshoot

I'm glad I'm not the only one.
So have you tried to do anything ?

I'm heaving the same problem.

At least nothing special about the frozen/quarantined apps. It's about the same stuff I froze (except for "Smart Log Service", "SystemBackupService", and "Talkback"). What ROMs you are on? Maybe that might shed some light (I'm on stock 4.0.3, v10h, and do not have that issue).

I'm currently on stock everything
Sent from my LG-P880 using xda app-developers app

Well, "stock everything" is not detailed enough. There have been several "v10" versions (with Android 4.0.x), and now there are also "v20" versions (Jelly Bean). You need to be a little more precise
