Battery life?

Hi all lucky owners of lg optimus 2x,
I want to ask you a question about battery life of optimus 2x . Is it really better than single cored ones or same, i m not expecting better life really
Sent from my HTC Desire using XDA App

There's a good review in the optimus 2x forum:
http://www.optimus2x.net/index.php?topic=156.0
Conclusion:
30mn YouTube HD (wifi)LG Optimus 2X: 9% battery​Google Nexus S: 7% battery​30mn Neocore (3D graphics)LG Optimus 2X: 12% battery @ 74FPS​ Google Nexus S: 9% battery @ 54FPS​8hrs of stand-by LG Optimus 2X: 2% battery​ Google Nexus S: 3% battery​

Wow, quite good !!!!!!!!!!!!!!!!!!!!!

I think that test is a bit flawed... PaulOBrien reported that the Nexus S exaggerates it's battery % quite seriously...

You are used o2x. What can you said about battery life of subj? On sleep mode? On used mode?

Here is an interesting test of battery life of the lg o2x.

my battery life blows :/

Well, mine has a pretty good battery....you know now I have time, so I just keep playing with it all day, so with auto-brightness and WiFi always on, playing pretty much all-day I got through 1 day without my charger. Without wifi and less playing I think 2-3 days could be easily achieved.

I am using V10d rom unrooted.
It happended several times now. I need to change SIM cards often as I travelled to different areas during my work. Before I pull out the battery,it is at 50%. After I change SIM card and put back the battery, it drop to less than 17%. It takes me less than a minute to change the SIM card. What happened to the battery??

Use juicedefender

I managed to get 3 days+ out of it under average use. Could probably easily manage 4+ with setCPU or something underclocking the processor and turning off data, etc.

i'd like to know too. My battery life sucks. Barely make it through a day now. On MCR FR17..

This is one of many threads about this.. But i'll respond anyway.
I had same issue, after some tests, i found out its GSM part of phone thats draining the juice. With airplane mode on it was about 3% in 8h. I was on BlazingDragon, with some apps, normal phone use It lasted 24h on standby without any use, no more.
Yesterday, i tried to flash (lastest for central europe) stock firmware, including baseband, simply i got the phone into factory state. And well, during night with data off it was 1% (yes, you are reading it right, i woke up with phone on 99%), now 10h later with lighter usage (some mp3, not much, a little of tapatalk, gmail push on) i'm at 78%.
I dont have any software except tapatalk installed atm. Dont think my problem with with BlazingDragon rom thou, i suspect some application caused it, but dunno which one
I think it will last 2 days with current usage, and several days with data disabled (using it as plain old phone only for calls )
PS: I dont use any JuiceDefender etc..

Iam using slicks rom, if i only write sms and surf sometimes, i have to charge every third day, but if i playing THD games, i have to charge after 3-4 hours

+1
the stand by time is really nice but gaming sucks out everything from my battery

Other than the battery drain during standby, my current observation is that, say if my battery was at 50% before I pull out the battery (say if I need to change SIM card), after I changed SIM and put the battery within one minute, it suddenly drops to less than 17%. Why the battery loss 33% in no time?
People keep saying that the phone can last a week if it is on airplane mode, or by turning off data 3 days, but then why we need a smartphone of such build?
Has anyone compare the other dual core or tegra2 phones in the market how they perform battery life? Do they have such awful battery drain standby? LG said the battery drain was due to incompatibility of tegra2 and android 2.2. Why sell the phone in the first place? This problem starts from day 1. LG no QC or just want hiding this problem from customer?

it looks like a calibration problem. Either 50% or 17% reading was false.

Just did two full days after reflash with MCR.

Battery Life- An experiment

Anderson Did an experiment to see how far the battery life can last on normal usage.The battery power was monitored using the app "Battery Monitory Widget"
And he came to the conclusion that The battery life could well last more than 2 days if you use just the communication tools (whatsapp, Facebook, sms) on a 2G network. With heavy data usage, the battery power got zapped out rather quickly.
You can have a look at the full experiment
optimus2x.net/index.php?topic=907.0

I'm kind of experimenting in this too..
Today i unplugged my phone this morning (6am) and its dropped to 97% now @ (3pm).
So thats only 3% in 9 hours..
I use Facebook widget which updates + Twitter widget same setting (both auto update every hour)
I sent about 10 text messages (also received about that amount) and made 1 phone call (about 3 minutes)
All this on 3G network, i dont save on 2G/3G setting

2G coverage is very suboptimal in Switzerland, especially if you are using a Sunrise.ch contract. Their 2G performance with Edge is about 100kbit/s for download. This is a joke. I am not able to use a phone with 2G and enjoy it. Therefore whenever possible I have to switch on 3G (which is of course also not great, but at least it is much faster).
Therefore, 2G is not an option at all for me.

I am running stock on mine and I seem to at least have found some form of "battery" drain. Trying to reproduce the usage.
But I charged my phone fully, and then restarted it and "at the moment" it is holding its power sorta alright. But when I use it normally it lasts like 7-8 hours before needing a recharge, even if its just laying on my desk and not being touched.
Ok testings done. These figures are after a reboot and where I have more or less left the phone laying on my table only having a short call, and otherwise reading a few emails and responding to a few texts. The entire time autosync was on, as well as 3G Data.
1H30M -08%
5H30M -30%
8H20M -50%
11H00M -68%
12H15M -74%
13H08M -79%
14H15M -85%
15H20M -93%
At which point I stopped the test and then put my phone in the charger. Tomorrow once it is done charging I will start up all the stuff I normally run on it, charge it to full and see how well it does there when I am not using the phone at all. Quite frankly I expect a large difference simply because that is what I have seen, but starting program and then exiting said programs and leaving the phone on standby "should" not impact consumption in my view at least.

I think there is something bad with my battery, because Battery Monitor Widget says that my battery is a 1200 not 1500, without doing nothing at all it lose 1% per hour and suddenly in 10mins drops like 6%, so in 8hs aprox from 86% goes to 68% (the phone doing nothing)
I have 3G always active, whatsapp and gmail, just that. Will try to do the test again with 2G, but what I don´t understand is why it says 1200 instead 1500.
Should I get a new battery? could be deffective this one?

You define your battery size in settings, 1200 mAh is default.

CM7 is the best for me

CM7 seems to be really good for me, i used 28% of it with medium-heavy use (no games, but wifi always on and a lot of playing about with) in 5 hours and at night i lost 3% in 7 hours sleep with 3G on. Not fully stable but seems better than sacrificing the smartness of my smartphone.

Lost 0% 2 days ago when sleeping for 9-10 hours i think
Today i lost 1% when sleeping for 9-10 hours
I am using 2g since i don't have 3g connection in my house.
It's a bit unstable but battery improvement is more important for me then some little bugs

No problem .
The O2X does not have good battery management, so it will drain.. getting usable results with mcr r15

Battery use

Can somebody help me out here? My battery life is really bad, today I lost about 10% battery indicator 4 hours with the phone lying in my pocket! When I use the phone its even worse. I am on cm7 nightly 09302011, and it seems like everyone brags about the battery life, just not me. 3g always on, bluetooth off, background data on, autosync off, no live wallpaper and å clock widget. What could be wrong?
Sent from my Optimus 2X using XDA App

Are you using a custom Kernel? Since installing the NeoBlaze kernel my phone has started using power on idle.. last night it used 40% charge while completely idle and not in use..
I don't really care because I carry 2 batteries around with me at all times, but it does seem changing around roms/kernels messes with battery life. Perhaps you just need to hit up eBay, batteries can be had for $2.80 shipped.

Without Juicedefender, 10% in 4 hours with no use is actually pretty good for this phone.. I'm jealous. I get that kind of battery life with data OFF most of the time.

No custom kernel. Thought I read in the forum that ppl got like 3% loss overnight. Maybe thats without data...
Sent from my Optimus 2X using XDA App

get widgetsoid and turn your data on and off (and 2g/3g) on and off quick and easy.
who on earth needs data running over night anyway ?
same as watching full hd videos on 480x800 screen..... thats just dumb

3g always on

I think this would explain why

I guess 3g is the sinner. Installed JUiceDefender and went from 11h to 32h battery life.

Not sure what happened to my phone, I'm getting 4 hours off a charge now with relatively light use.. just some web browsing and screen off idle half the time.. Going to try topogigi rom and see what happens.

Me too

hp extreme sr2 battery drain

Hi guys.
I have installed in my lgo2x the kernel hp sr2 and HP PerformancePack V8 Lite.
I realized that the battery consumption is very hight.
For example this night the percentage battery is passed from 100% to 94% with only 2g turned on.
My phone mount rom stock v20l and BB823.
it is normal?
solutions?

If night you mean sleep for 8hrs and it drained from 100% to 94%... I think that is normal.

but before, with stock kernel, i did not have this consumpion, i found the battery to the 100% or 99%.
is the neoblaze kernel better than hp kernel regard battery drain?
sorry for my english

1% per hour is a fact of life. The phone still has to communicate with cell towers to ensure it's on demand ready to accept a phone call/text message/email push.
Put the phone in an area with better reception and it wont have to try so hard to make a signal.

When i turn on 3g and surf,,, battery drains very fast lyk if its 90 in 1 hour it gets 30
Can i place a replacement for the battery???

Draining 60% battery while surfing over 3g for 1 hour is a bit too much, are you streaming video? try to calibrate your battery.

That's not normal. If you believe your battery is faulty hit up eBay and get one of the $2.80 ones to test.
But try a calibration first.

Sent from my LG-P990 using XDA App

You can clear battery stat from cwm or download app called battery calibration, charge your phone to 100% and press calibrate and use your phone till the battery is fully depleted, till it shuts down by itself. Then charge it up again and use it normally. Monitor is there is any difference after 2-3 cycles, if not, you have a bad battery.

Use [ROM] Rebuild of Leaked V20o Gingerbread Update , my battery take +24 hrs to get off.

[Q] Bad Battery Life?

Is the O4X's battery life as bad as gsmarena is saying? Just a little over 4 hours of video playback and 4 hours of web browsing?

If you read the comments of the blog article on it, you will see that there is a lot of discussion over the brightness.
By comparison to the SGS3 and One X, the Optiums has a much brighter screen which will mean a lower battery life. Of course if they set all the phones to the same actual brightness (not percentage) the numbers would be different.
I am currently waiting delivery of my 4X, but after I have conditioned the battery (let the handset configure itself to the battery), I'll definitely be seeing what its capable of.

Alright thanks, I hope you'll be able to get back to this thread when you find out more.

I've had mine since friday and I think I've charged it about 3 or 4 times now and the battery life is getting better. It lasted only about 2 hours when I first charged it and started it for the first time. But I was using it constantly.
Today I started it in the morning (fully charged) before going to work and now, 10 pm, it's been on for about 16 hours and I have 40% left. Data have been on all day and I've been signed in to Google Talk all day, I've browsed the web for a total of aprox. 1 hour, used the camera, tested the GPS and been chatting with a friend on talk. So I'm pretty satisfied so far.
It's better than my O2X.

That's good to hear. How many hours was the screen on?

I'm not sure unfortunately. But i would say between 2-4 hours.
Edit: okay it was a little less than I thought. The. Battery usage in settings says the screen have been on for two and a half hours. And that's including the time I have used after 40%. I'm down to 25% now.

My Battery lasts after a few cycles all over two Days with medium Usage (No gaming - WA, FB, eMail)........

i ca go for 1 day, with a bit gaming and usual use.

I have slightly longer battery life on my 4X HD than on my Nexus S when using the phones in the same way (casual use). But I think there is room for improvment on the battery life with more optimized software either from LG or when we start seeing custom roms for this device.

I charged mine to 100% and just dropped 8% in 25 minutes, 20 minutes of that was driving and not using the phone, no Bluetooth or anything like that. The battery life is shocking and can't wait for extended ones to become available. Besides that I truly love this phone

How many complete charge cycles have you done?
Sent from my LG-P880 using xda app-developers app

When I got my p880 I did 3 battery cycles, and I could only get about 8 hours of standby alone, no other use at all. I then did a factory reset and formatting of the memory card, which I hadn't done when I switched from my old SE X8. Now my p880 can easily go more than a day with some gaming, calls, browsing etc. My guess is that old android files on the memory card was the reason for the bad battery life. No expert though, maybe someone else has a better idea.
Today I tried the Chrome browser, and it really drained the battery. Something like 20% after browsing for 15 mins. Anybody else have experience with this?
Overall I'm really happy with this phone, great screen, fluid operation, good battery.

I've had battery drainage issues with the chrome browser as well. Even in stand-by the browser would drain the battery. It has only happened like two times for me in the four weeks i've had the phone, so not a biggy but still something you should be aware of, if you experience battery drainage issues
