Battery power for LG Optimus 2x

Hello all!
I am new to the forum so I hope make it without any errors.
I bought the Optimus 2x cellphone last week whith the hope of getting the good one (the one without freezes and black screens) fortunately the cell worked very nicely. I updated to gingerbread and I feel it very good. But I have the good known problem of battery consumption.
Now I have a battery related question. After the update I charged the phone and get the battery indicator stuck at 100% I rooted the phone, installed Battery Calibration and calibrated the phone (left the battery to reach 0% then fully charged to 100% hit calibrate and left the telephone fully discharge again)
The issue is that when the thelephone was at 100% the voltage indicator of the battery calibration was in 4100 mV and here comes the weird thing. When reached 0% the voltage indicator was saying 2000mV.
My question is if this values are right. Someone with good battery duration and the Battery calibration installed could tell me the correct values? I thought that the phone shut down when battery was down to 0 mV but maybe the problem is that my battery is just using "half" battery.
Sorry for my english. I am not native english speaker.
Any help will be highly appreciated.
Thanks

That is voltage, 3300mv = 3.3 volts.
Fully charged the battery would be at 4180mv, fully discharged is around 3200mv usually, or a bit higher.
The phone shuts off when the battery gets below the usable range, which I believe is slightly above 3000mv.
So yes a range of 3.3 to 4.2 volts is perfectly normal for a 3.7v battery.

Hi! Thanks for your reply. So I think I should get used to it. My battery doesnt last more than 12 hours of my regular use. A some internet browsing and some messaging. No music, videos, or games.
Someone recommends the extended batteries of 3500 mAh for this phone? That will make the phone last more time?
Thanks in advance!

Hi Reaper511989, I have bought an extended battery from HERE. It is fatter, but not ugly. And the battery lasts a lot longer. I use it when I'm travelling. I have no idea where in the world you are, but the battery was from a company in the UK.
Have fun. Anil

Huge Battery drain on DjangoManouche/Guestekrnl
Hi,
I was on CM7 kang of temasek and I decided to flash a stockbased rom.
Now I'm on :
DjangoManouche 1.2 rom
Guestekrnl V1.6.1
BB V20Q with ril
I am using Go launcher which comes with the rom
The battery drain is incredibly huge, 8 hours tops with very little use
Anybody some ideas ?

your lucky. i get 6. if im playing 3 albums of mp3's during work. nothing on. just 2g.
imagine if i turned on gps,wireless,bt 3g/4g ahhhh . (cant use fone how its sposed to be used) have ot turn it DOWN a notch. its to HUNGRY on juice. seriously lookin @ one of those MUGEN batteries.

6 hours is just wrong... in the most intense usage you should get 2 hours of screen ON time.. Wifi with 2g on trolling forums with browser/tapatalk should be 4 hrs.

6hours listening to music is pretty normal. If you want longer battery live, stop using the device.

Well in that case you might wanna repair your device since you seem to have the same issue with all roms. That should not be the case that it uses the same amount of battery without using it, especially if no app is loading the cpu....

well actually. cm7 i got about 5-6 hours batt life, cm9 i got no more than 8, GB (stock rom) can usually go from 5-8 hours. but with no bugs. so i am back on GB.
so i dont think device is broken/dodgy since the batt life fluctuates a little. depending on the rom.
my main issue is, ive been reading about ppl using froyo and going to GB and having mass battery drain. now im thinking about going to froyo.

Could you please share your findings? Since I'm having the same problem and started thinking about returning to stock as well.

[Q] Battery problems G1

Hi to everyone! I have a g1 and I decided to use it again. I replaced the battery for a new one (I bought it few days ago). When I used after charging it all night it just lasted 3 hours. Then I googled for solutions and I did all what I found (charge it full and reset battery stats and let it drain all, charge it with the phone off, etc) without results. Then I tried one Barry with more capacity (the ones that you need to change the cover) that a friend have and was the same. After more or less three hours, the phone turned off. I had cyanogenmod 7 installed with the latest radio and spl. Today I tried with stock room, unrooted with the same results.
If someone knows a solution, please let me know. Thanks

It may be your ROM, but this is very new to me, even those big ones? Try another ROM:FroyoByLazslo is my favourite and fastest

I'm checking with the stock rom, but I'm going to give a try. Thanks!

Hi,
maybe you overclocked it very much; this can use very much battery. If you want to save energy, you should undervolt it...
Hardy

Hmmm, I don't think is that. I tried with the stock room (1.6) and was the same. And this morning I tried to use the phone, but I had decided last night to turn it off to save battery and was dead! Maybe the phone has something... today I flashed the room froyo by laslo, looks good and is fast! I'm going to underclock it and see what happen. Also I read something about a draining problem when you connect it in the laptop through usb, might it is the cause of all this?

Only with some kernels, if your drain problem is due to software then flash a different kernel

Yeah, may didn't wipe during a ROM change?
PS: You're welcome!

HI, after checking all that you say. I wipe all and after I charged the battery, y wip e the stats and now is working better! With the normal one, I get 6 hours on standby and with normal use, 4..... I tried with 2200mhA and I get 12 hours with medium use, but I with this one the phone is bulky..... BUt well now is my gps!
Thanks!

No prob dude we are here to help the guys who need help, that's why it's a forum XD

TC, you must understand that all G1 batteries are quite old now. They were made betwixt 2008-2010, batteries begin losing their max charge right after they are made in the factories. It's only natural for your battery life to be poor, batteries can be damaged heavily by heat sources, my notebook's battery life became 5 Minutes b/c the wear level was extremely high. I assume your G1's battery is in "bad" condition cell wise. Either calibrate or buy an OEM battery(3rd batteries are tricky). If you calibrate try one of these...

Also if you need battery you should honestly stick with cupcake, donut. Anything past that is already sluggish and pushes the G1, which means the CPU is always at max which leads to shorter battery. And lets not forget the post donut versions have more services and what not.

What's wrong with 3rd party batteries? In my experience I've had two different ones bought off eBay and each worked better than my new OEM battery.

[Q] Battery--Please Help!

Hey everyone,
So this is my 2nd Android device. I had the Inspire and this summer I picked up the Vivid. I think the phone is fantastic, however the battery life has been nothing short of horrendous.
For whatever reason, my phone can only last 90 minutes on a full charge. The backing gets warm quickly and the battery percentage decreases very rapidly. The battery life continues to decrease even when the phone is locked.
I have tried basically every ROM out there, from Holics to Cyanogenmod. Some are a bit better than others, but none can make it over 2 hours for me.
Is there anything I can do to fix this problem?
***​
On a side note, I love the work that has been done on the development side of this phone. I never thought I would see the day when I would be running CM.
Thank you all in advance. This truly is a great community.

Uhhh...
Factory reset?
RUU?
if you still have the problem... get better battery stats... figure out your wake lock...
Or... get cpuspy and figure out what's got your processor hung up

[Q] battery saving roms?

Does anyone know of any roms for the HTC vivid that will extend my battery to 15+ hours? I have yet to find one. Please also post good kernels that will help save my battery. My battery on the HTC vivid sucks. I can't even get through the school day without my phone draining to 10 %. My vivid is completely stock with ics update. I would like an ics Rom, the only thing I do is listen to music with the screen off and the phone in my pocket. I can't imagine why my battery dies so much. Please help! I only listen to music for about 40 mins in the morning!

I would be willing to bet that your problem is programs you have installed...
Either that or excessive screen on time...
Both of those problems aren't solved by ROMs

Charging ONE

Anyone know how strong of a charger this phone will accept and use efficiently and safely without causing a problem? I haven't seen this asked but the battery life is terrible on this phone. Honestly the battery is just not enough mah to be efficient on the phone. I wonder what kind of battery life people are getting who actually have lte?

Doesn't matter if it's 'too strong' as it will only pull the current it needs. Too small is what you need to worry about.

You must be doing something wrong then or setup something that is eating away at it. I have had my one off the charger now for almost 11 hours and I'm at 92%. Obviously I haven't used my phone hardly at all today thus far, but even with moderate usage I have been very pleased. I have been losing 1% about every 45 min today. That's solid
