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

Low battery life

Hello,
Since I bought my cell (about 1 year ago) I've been experiencing low battery life. I've used different roms, tried about almost everything to decrease battery consumption (2g, no wi-fi, etc) but it still lasts about max 8h (moderate usage). While using continously it lasts max 2-3h. So is this normal, what could I possibly do about it or should I just buy a new battery?
Currently running Nova Hd RC 21-39 with Supernova pre RC-3 kernel.

No that's no where near normal. Could you get a screen shot the battery usage ?

Not sure if you ment those stats, just tell me if it are not the right stats.
Translation:
Signal mobile network
Wi-fi
Turned on
Screen on
Charging

Other stats are:
Screen - 92% (on automatic though) Wi-fi - 7%
Mobile stand-by - 3%
Yes, it makes 102% kinda weird ^^

don't sorry about screen percentage, its heaps inaccurate.
Could you install system panel from the market and tell me what the cpu's are doing on idle?

Nothing really special, it varies tho sometimes it goes to max instantly and drops back within 2s

same issue here..
running nova hd RC22-41..

I'm pretty sure the battery if screwed. You can pick one up off eBay for a steal.

Your cpu is at 50% all the time, how is that nothing special?
Install os monitor and check whats using the cpu.

Looked at OS monitor and only thing that consumed cpu is android system (5%) and system (2%)
Sent from my LG-P990 using XDA

I'm running CM7.2 RC1
Worked fine for a while and now th phone looses 10% per hour (idle). Checked OS monitor and System panel but there is nothing eating CPU or something that shouldn't run.
Only thing that changed between the two phone states (fine / annoying as hell) is some experimenting with GetRIL. So I re-installed the RIL (v20l) that worked fine before but it didn't help.
Also I have two batteries. The original LG and the Andida, both give crappy results. Think I'm going to try to go back to the stock ROM, see if it helps.

i just did that. having two batteries will probably confuse the calibration unless u calibrated them the same way. either way, from what im guessing, not fully discharging the batt will mess the readings as 1 constant battery ?

According to my earlier measurements the Andida is also about 1500 mAh in real life. So it shouldn't differ much. From what I read clearing the battery stats doesn't do much, said some Google developer. I'm back to v20r now and it looks much better.
40% in 7 hours, before it was 10% per hour idle.
Today it was even better, ~30% in 8 hours. This looks more like I was used to.

[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?

yes, I have same problem and do not know how to fight with it.
here http://forum.xda-developers.com/showthread.php?t=1834028 something said about clocking down CPU and undervolting. because this stuff sounds like rocket science for me, i have not tried.

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....

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.

Bad Battery performance on my OB.

Hey folks! I have recently started observing that my phone is consumimg excessive battery. I really cant seem to understand the cause, but for sure, I know there is an issue unknown to me. As I can see and observe, the situations I've faced are as follows:
1. When fully charged and unplugged, usage on wi-fi, screen on and some music leads to empty battery in almost 2 hours sharp.
2. When fully charged and unplugged, wi-fi off, sync off, GPS off, data off and literally everything off including the screen, then from 100% charge to 25% charge in 8 hours.
3. When I use the phone, as mentioned in point 1, suppose the phone discharges from 100% to say 60% in 40 minutes, the thing I do is turn the screen off. Then as soon as I do this, the battery level rises up until I turn the screen on again. Funny! :/ xD
4. Now the final case is this. When I turn of the phone at suppose 20%( probably unreal charge stats), connect it to a charger, and then while connected, switch on the phone, the phone gets charged up to like 50% or so. Epic fail!
5. Oh I almost forgot, battery usage charts show Android OS consuming 40-85% of the charge at all times in which the wakelock stats are an alarming 3-4 hours as per the 2nd point. Screen consumes 30% of the charge and Android System follows
I am posting my battery usage screenshots here.
1. The first screenshot was the one before I rebooted at 20% charge. Look at the roller coaster battery stats. XD
2. The second screenshot is the one showing all the stupid processes consuming excess battery.
3. Observe the difference towards the extreme right of the third screenshot and the first one. The third screenshot was the one after I rebooted. There is a long white line at the right end of the third one which shows the rise of battery charge from 20% to 56% precisely. Bloody hell!!
:/
Kindly, anyone who feel that they can help, look into this matter and suggest me good options to follow.

Two more screenshots!
Just look at the time at which each screenshot was taken and compare the stats Yourself. This **** is freaking me out each day.
LOL and the charge was at 19% at 00:33. At 56% at 00:39 and now at 82% at 01:15. Highly quick charge and discharge. what do I do?

Mention your rom and kernel.

Umm the screenshots are from the Xperian UI ROM. I dont know which kernel it is, but the screenshot here can help You maybe. But but but, I faced the same problem of excessive battery drain even on the official 2.3 ROM of LG. Every ROM is having the same effect more or less.

I think ths is because of the xperia apps. I remember when i used optimusZ by eminent. The drain was high, even when i removed it. Check your wakes with betterbatterystats
Sent from my LG-P970 using xda app-developers app

Well You are right about Xperia apps. The Facebook inside Xperia extensions suck up the battery. But that is just a part of the story for me. I've been having the same amount of consumption in almost all the ROMS I've tried so far.
