[Q] Problems with battery - LG Optimus 2x

I have been trying to figure out how some of you guys get these amazing battery lives and I'm struggling... I have flashed quite a few roms in the past several days (ICS, CM 10.1 , 10.2) and all of them come with the latest kowalski kernel M1 or exp 126.
with kowalski kernel M1 on TheROM build 13:
the battery lasts only 5-6 hours with about 1 hour normal usage and screen on time...
when the battery goes to 0% and phone turns off I plug in the charger and switch on the phone and it starts from numbers like 70% or 60% ! :silly: after the charging is done I leave the charger on for a few hours at 100%, then I unplug the phone and use it normally (nothing heavy, just few minutes facebook and email with some calls and browsing) the most I got is around 5-6 hours with 1 hour screen-on time :crying:
with kowalski kernel M1 norh on TheROM build 13:
same story but here the situation is worse, after about 5 hours with data and wifi mostly off (just manually switched on when I needed to check something), the battery was about 35% and then suddenly it jumped to 0% and phone shut down! I turn it on and it shows 20% and it works for few minutes then again jumps to 0% and shuts down... :crying:
I have done everything I could and followed any advice I could find related to this issue and nothing seems to help. I flashed the roms after factory reset with fully wiping everything including the internal SD, and I have done at least 4 cycles of full discharge and recharge with the phone turned on for calibration but the situation stays the same.
The battery I use is a new OEM from LG and I bought it 2 weeks ago because I thought the old battery was the problem.
I am currently using TheROM build 13
can you please advice what could solve the issue or what am I doing wrong?
I attached the logs I got using SysLog, on both kernels hope it provides some clues.
I'd greatly appreciate if you can help me out.

That is really frustrating, but... KK battery driver is somewhat intelligent and needs at least 3 full cycles of drain and full charge (100% + another hour) to be calibrated. I have good battery performance with Pengus' CM10. It is really worth a try.

@oneearleft Thanks a lot for your reply, I know about the calibration , I have done that every time....
unfortunately I have the battery problem with all of these roms
CM10 "Look Ma! No Hands!" Edition
CM10.1 - tonyp - T-Build 05
cm-10.2-20130824
Stock ICS OptiX Rom
TheROM - build 13
apart from the battery life, everything else is working perfectly with TheROM for my needs, I really hope to find a way to fix the problem
waiting desperately for KK 3.1 kernel ... hope the battery driver gets a good share of pengus' magic

How old is your battery? After 17 months, I bought a new stock battery. The difference was tremendous.

The battery is new OEM from LG, I bought it 2 weeks ago to see if the old battery was the problem...

It seems you are doing everything correctly. Have you tried the app Better Battery Stats to record what is draining battery?

High battery drain i9001

Hello,
I have a problem with the battery drain on my galaxy s plus.
When the phone is standby its using 40-60mA. When I have lucky at night it is 20-40mA.
I didn't find the problem. 4 weeks ago with my htc desire and same apps and settings the battery used 8-12mA in standby day and night.
3G and Wifi always on.
Standard 2.3.5 rom. Push apps: gmail, gtalk an whatsapp (same as on the desire).
Yesterday rooted and deleted a lot of system apps to clean up the rom. Flash this morning a custom kernel with CWM. Nothing helps
I was happy with the bigger battery but with this battery drain.....
Has someone a idea?
Are there more people with same problem?

Here is a logfile from better battery stats.

My cell standby is also very high rougly about 45% and my phone idle will be also around 40%

[Q] What is normal battery drain?

What is your normal battery drain when your phone is idle? I have an hour and 15 minute drive to work each day and my phone sits idle the entire time when I get to work I notice that my battery has drained about 3%. Is this normal or is this high?
I'm running teamhacksung build 16 with glitch beta 3, of course this has been the case for every ROM I have installed. Btw I keep wifi and gps off at all times and I'm syncing only gmail.
The reason I ask is that I was given an iphone for work and I couldn't believe the battery life, of course I could never leave android for apple...I just can't customize it...
Thanks in advance.
3 % a hour, that's high, im on kk4 based rom & kernel and my cappy drained average 1% per hour

Perhaps during your drive you are going through some areas of weak signal where the phone needs to work harder to stay connected.
You can look at Settings to see what has been using your battery during that hour and a half.
That's similar to the battery life I'm getting. I think I can get better drain if I don't overclock

^same. Its also the same if I'm running cm7. On THS ICS, at most I can get 2 and a half hours of screen time o.o

I have seen my phone idle between .5% to 3% based on strength and stability of signal, no other factors involved. Since traveling at vehicle speeds = less stability. It's probably the reason for your loss, you can try different modems to see if one talks to the towers better so hand-offs go smoother.
leaked from my ICS- FUSED SGS I897 contaminating you via XDA app.
Here are a couple screen shots I took after my phone was sitting on the counter idle for a little over an hour.

Yeah I'd say that 3% in 15 minutes is high - I probably drop 1% to 2% per hour or so when idle (but I keep wifi and mobile data disabled when not in use).
Even when I'm work though where my cell signal is weaker I don't think I've ever seen my battery drop 3% in 15 minutes.

Phone/battery problem

Hello everyone
I need help with a problem I have had since a week or two.
The battery life of my phone is drastically low (check screenshot).
I bought 2 additional batteries, one genuine battery and one 3rd party battery. And they didn't help.
I am using the latest CM7 kang from temasek with the latest Etana kernel. But I have tried to downgrade to the stock LG rom, and still the same.
I haven't got any "hungry" apps running in the background because I freshly installed the latest CM7 kang for testing.
I think it was caused when I pulled out the battery when the phone froze, I was testing my new bought HDMI cable. The battery was fully charged >95% and when I pulled out and reinserted the battery I noticed it had about 6% left.
I think it has something to do with the insides of the phone.
And I hope someone can help me out here!
In the screenshots, I left the phone untouched for more than 12 hours.

Yeah I was getting the same with CM7 some weeks ago.
I was also having the battery drain in about 8 hours from full. It all appeared suddenly, with no new apps installed and good batterylife the day before. Was using stock 20q and changed rom to wiui, wich helped. Never figured out what caused it, had similar battery history as OP.

Thanks, I will try WIUI out.
I have also used CM7 and a couple of stock based roms to and never encountered this before. It all seems pretty random to me.
Too bad... It didn't work.
I'll try to flash different roms.
Thanks again.
Have you tried to reset the batery stats in CWM? Might help...
Charge to 100%, reset stats in CWM, drain till the phone shuts down by itself hand charge again to 100%

I once had this all of a sudden with the MoDaCo FR19.
Hot battery, 8h till full discharge.
Never found out what caused it, but a factory reset, FULL wipe and reflashing sorted it out for me.
Good luck solving the issue.
Thanks for the suggestions.
I tried resetting the battery stats multiple times with no effect.
And what is the "good" way to do a full wipe?
I always format the data/cache/dalvik/system partitions. Is that how you do it?
Make sure your baseband and ril match, if not sure check stickies
Sent from my LG-P990 using Tapatalk 2
Nothing works!
I tried changing roms, kernels, basebands, RILs and I can't seem to fix the problem.
Does anyone have other tips?
When I bought the phone, my number 1 concern was the battery life. I easily reached a minimum of 24 hours of average usage after I spent a long time looking for battery saving techniques/tweaks.
But now, I am very disappointed!
I really hope this can be fixed!
Well, i think everybody has been through this... In my case drain was coming in 8 hours time, but with the complete wipe and the rom changing it got away, and I never really bored in looking for the thing that was causing the problem.
This morning i was very surprised to see that during the night ( 3G on ) my LG P990 consumed only 1% Battery per Hour .
End charge at 12PM ( 100%) , founf at 94% at 7AM
This, to me, is a great resoult!!!!

[Q] Good battery ROM

Hello people,
first of all I want to say that I know there are more questions like this one, but I couldn't find an up-to date one.
I'd prefer an ICS or later rom since.. well the GB roms are quite outdated, but if you know a rom which offers a great battery life don't hesitate to tell about it.
I'm corrently using CM10 unofficial from Pengus77:
http://forum.xda-developers.com/showthread.php?t=2058231
Here is a screenshot of my current battery life with light use (no data, little wifi for whatsapp and sometimes checking my timetable screenshot) :

Hello!
I'm using Paranoid Android and I like it a lot. Battery life is really great. I'm using my phone from morning till the night and almost always battery last long enough. I'm using it for surfing, listening music, phone calls, messages so I think that this is really nice rom.

Wise choice.
Note: Don't judge the battery too fast. Wait till it have done a few cycle charges (meaning: plug charger in at a low battery percentage, keep it charching till its 100% - repeat few times.).

Yes, I will (although a lot of people say you should only charge to 80/90% to not overcharge your battery)
What governor are you all using btw? just normal interactive?
Update: installed the rom, all my apps, filled in my preferences/personal customisation etc. and I lost about 25%
so everything seems to go quite well with this rom.
Just one question:
what is a good alternate theme instead of the xperia one?

Well, here are the results of the PA rom:
As you can see the battery life is MUUUCH better. This is at almost the same usage as seen on the other screenshot so It's a fair comparison.
Thank you for informing me about this great rom and as a token of my esteem I'll give you all a :good:.

Note 2 Extended battery Review. 7600mah

Hello guys and gals,
I have received the extended battery that i have ordered on last friday and has been using it for the past 3 days.
The model i have ordered is 7600mah extended battery with NFC and back battery cover.
I can't confirm the battery capacity is 7600mah or not but it sure have increased my standby time by double.
The back battery cover has a very tight and good fitting as good as the original and it looks good too.
The battery does add weight and bulk to note 2 but it is worth the standby time.
I am not here to promote this item but just to share out my findings.
The link for the battery is :
http://www.ebay.com.my/itm/27127178...eName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
and i have only ordered this case yesterday and i hope it will fit perfectly....

Thank you.
That battery might be a dud. I get way over 24hrs of use and over 6hrs of screen time on my standard original battery. And that's on the 4.3 rom. I used to get closer to 9-10 hrs screen time on the original 4.1.1 rom when I first got the phone.

depends on your usage bro, for my stqndard battery, usually i need to charge after 7 to 8 hours after i unplug from my charger after a full charge while this extended battery i use now doubles the time.
different people have different kinds of apps on their phone so the result may varies and very subjective.
i also can get over 24 hours of stanby time if i only have very basic apps installed on my note 2.
Cheers.
Same for me, 10h on 4.1.2 and only 6 on 4.3.
I will try slimbean this week to see if its better.

Fair enough, I'll get a full charge under and do it again. I'm estimating it was About 4-5 hours there.

I think I know why the reactions were a bit too emotional - a screenshot of the screen up time would help to prove your point. And you don't have to estimate, just when viewing the battery graph page, click on the Screen entry, the precise time is there.
