Maybe I'm just expecting too much from the battery, but my G2 was able to go 8 hours and be at 70% :(
[T-Mobile LG G2x] dalepa:
I did a reset yesterday, and im happy to report that it appears to work. The battery drain now appears to stop when the phone is idle. I only have a few apps to add, so if i find more I will report, otherwize we have a may actually have a solution.

Here's the before and after

Before reset

After Reset. The overnight drain(while no activiy should have been occurring) was was minimal and the drain slope is much better
[T-Mobile LG G2x] allen099:
I'm not sure whether I have an issue or not. I feel like the battery was fine during the week but right now, it's been on for just shy of 3 hours and it's already down to 90%. I have the battery monitor widget installed and it's a steady decline; doesn't appear to be a rogue application. I've had only a few text messages come in; no phone calls or email.

I did a factory reset as soon as I got the phone on Tuesday. Does this sound on par with what you guys are seeing when the phone is idle?
[T-Mobile LG G2x] Casao:
I'm seeing a drain of 10% battery life an hour, at the moment, just from sitting idle.

I'll be giving this a try tonight when I've finished some **** I need to do, thanks a lot for this thread.

Is there good evidence one way or another on rooting? I'd really like to root, but if it's part of the problem, I'm willing to wait for CM7.
[T-Mobile LG G2x] Profondo_Rosso:
Honestly, that's about normal (maybe a bit above). For reference, I went to bed with a 99% and woke up 8 hours later with a 55% with absolutely no use and wifi off. And when I actually use the phone I get a loss of 10% to 12% per hour.
[T-Mobile LG G2x] Profondo_Rosso:
I'm also losing 10% per hour. I'm going to try the factory reset I think
[T-Mobile LG G2x] allen099:
I'm now a little over 5 hours and down 31% with minimal usage still. Battery status shows cell standby is at 40% for 5 hr 24 min. Phone idle is next at 4 hr and 27 min. I've discharged it 3 nights in a row and last night I charged it up from 25%.

I did root the phone and noticed no difference. I really look forward to the CM7 ROM as well, but my experience has always been (since the N1) that their ROM ate up slightly more battery than stock. All of a sudden I'm not crazy about this battery life though.
[T-Mobile LG G2x] jink25:
I am suspicous now of the qik video chat app...it is running constantly in the background in order to catch incoming chat requests.

After my last factory reset I didnt re-enable it by entering my user ID/password...now that I just set it back up battery use appears to have gone back up. So far not as bad as I was initially experiencing but noticably higher.

Went from 2-5mA idle to nearly 18mA...not cool.
[T-Mobile LG G2x] Nivek91:
If I factory reset, will I lose root? Sorry for the noobish question
[T-Mobile LG G2x] JHaste:
Well I just killed qik and i went from 30 to 27... lol i have a lot of **** open but I am thinking this may be a phone where I need to use a task manager more frequently or on an automatic setting

I wont lie my battery life has not wooed like my n1's did... Id get 2 days of normal use out of my n1... I think more than anything we just need some custom kernels...
[T-Mobile LG G2x] shahp:
I noticed how poorly the battery life is on this compared to the Galaxy S i had for a few weeks before returning it for this one. Part of the problem is that there are simply some tasks that cannot be killed, or restart immediately, like T-Mobile's My Account, App Pack or Wifi Calling among others. Is there a way to completely kill these things from ever starting? It's pretty annoying.

I'm going to try a factory reset later, and see what that does. All else fails, I'll return and hope I get a good one like some of the folks here?
[T-Mobile LG G2x] Profondo_Rosso:
I keep finding telenav and carhome running.

That must be part of the issue. Nevertheless, I just did a factory reset and will report back.
[T-Mobile LG G2x] electric33l:
It seems that the source of the problem has been located according to this thread:

http://xdaforums.com/showthread.php?t=1047749

Can anyone who has used the fix post a logcat in the thread to verify factory reset/power cycling fixing the underlying issue?
[T-Mobile LG G2x] shahp:
I just did a factory reset also to see what would happen, but when i use Advanced Task Killer, it shows App Pack, Car Home, and a bunch of other stuff I clearly dont want running to be available. A kill command doesn't quite finish them off. They're like roaches!
[T-Mobile LG G2x] Profondo_Rosso:
Just an update. I did the factory reset, and I have to say the battery life has improved dramatically. I'm almost three hours off a full charge, and I'm still at 92%.

For reference I lost about 8% an hour last night while not touching it at all. No text, no calls, didn't even turn the screen on. And when I did use it, I was losing about 12% per hour.

This does work, though I wonder why, exactly.
[T-Mobile LG G2x] electric33l:
My guess is that factory resetting disables the ping that the phone shoots off every 1000 milliseconds discussed in this thread.

http://xdaforums.com/showthread.php?t=1047749

Some sort of bug that shipped with the phone, something they forgot to turn off, i don't know. People more knowledgeable than me will give you a more technical answer. :D
[T-Mobile LG G2x] flak0:
I

This is the thread I started, thanks for posting it here. We def need to get to the root of what is causing the gsmdatatracker to poll every 1000 milliseconds. My request is those of u who have done the factory reset, can u please post a logcat. Thanks
[T-Mobile LG G2x] jink25:
Confirmed qik video chat is a complete battery hog once you register the service on your phone. Do not start it again after a factory reset!
[T-Mobile LG G2x] aironeous:
Bloatware freezer from market. Freeze anything that is using your 4g constantly and I think that includes maps update also.

[T-Mobile LG G2x] DebauchedSloth:
I bet this is that logmein crapware.

If I were T-Mobile, and I was putting a "rescue" application on a phone which would allow me to remotely drive someone's phone (which would appear to be the purpose of that logmein crap), I'd want to be pretty damn sure it was only something *I* could activate.

The simplest way to do that is to ensure that it could only be activated over MY private network.

I'd do that by only allowing it over GSM.

So, I'd tell the logmein guys to setup a process which periodically turns on GSM data and pings to see whether it should activate itself. Then, when my CSRs want to remotely take over a phone, I'd send a ping over that GSM network, logmein would see it and take over the phone.

This would explain why GSM data is coming on even when we're on Wifi.

It would explain bizarrely short battery life.

And it's one more reason to get rid of logmein. I mean, seriously, who wants their phone to be remotely controllable by anyone? Even assuming T-Mobile got it 100% right, that's obnoxious. If they didn't, you have a remote exploit sitting on your phone, right now.

And it's maybe waking up every now and again, turning on your GSM data, sucking down battery, and phoning home.

How annoying is that?
[T-Mobile LG G2x] futty:
Will try this. Just a little bit ago my battery drained 3% within 15mins

My mytouch4g barely drains but I'm hoping that's the miui rom that it runs
[T-Mobile LG G2x] Cheeze[iT]:
Can we do a factory reset and restore from a old date it does that cancel it out?
[T-Mobile LG G2x] donutman:
What? I don't see logmein as a stock app?
[T-Mobile LG G2x] DebauchedSloth:
It's not. It's installed and running in the background.
[T-Mobile LG G2x] mdavislv:
After 30 mins of usage reading News & Weather and XDA already down 10%! Ran Where's my Droid Power and noticed that Wifi-Calling is around 25% of usage.

Wifi and Wifi Calling are currently disabled.
[T-Mobile LG G2x] hanged_man:
Like I said in the other battery thread, I've compared the log generated by alogcat before and after the facotry reset and I can confirm that the gsmdatatracker is still there happening every 1000 ms
[T-Mobile LG G2x] DeezNotes:
For me, gsmdatatracker logged every 1000ms (every 1 sec) only when the screen was on. When the screen turns off it doesn't log those messages.
[T-Mobile LG G2x] CB620:
What about the battery calibration trick? Ive done it with all my phones and it worked like a charm. I normally do it 3xs and my battery becomes more than useful after that. Once roms come out for this phone the better will be more than great. Its a project in progress.
[T-Mobile LG G2x] alex7619:
Well my battery drainage fix is leaving it on 2g for everything unless im on the net or youtube...Took it off the charger at 10:30am, its now 4:42 pm and its at 70%. This was after mild texting and calling and close to 40 min on google navigation.
[T-Mobile LG G2x] laker666:
Can anyone confirm that a factory reset cures the battery life issue?
[T-Mobile LG G2x] Prod1702:
the reset isn't what helps 100% its the power cycle that is also helping. I have done 2 full power cycles and i am seeing better battery life but cell standby is still a huge power drain on the phone. Its getting better but i don't think it is going to be what it should until CM is out.
[T-Mobile LG G2x] laker666:
Describe your power cycle process please
[T-Mobile LG G2x] TheMightiest1981:
I've power cycled and factory reset this thing 3 times and as much as I hate to admit it, this device has battery life much like the HTC Thunderbolt. I had the Thunderbolt for 10 days before sending it back, and just like the thunderbolt when 4g is active battery life is being demolished. Unlike the thunderbolt at least I had 3g once I switched from 4gLTE, with T-mobile 4g is 3g hspa+ and 2g is edge. The G2x itself is an amazing device, and quite frankly the most impressive mobile device I've come across. I'm just spoiled I guess because the Droid X has the most impressive battery life I've every experienced from a smartphone, I just wish it wasn't on ****ty ass verizon and it's ultra slow 3g. I just hope this issue with gsmdata connection tracker is resolved soon.
[T-Mobile LG G2x] hanged_man:
I have done factory reset and I confirm that I didn't see any change, it still drains about 10-13% per hour and that's coning from a moderate to low usage, I find that rather unacceptable
[T-Mobile LG G2x] TheMightiest1981:
10-13% wow your discharge rate is excellent, mine is about 15-30% per hour if I leave data connected.
[T-Mobile LG G2x] wondercoolguy:
I did the factory reset thing last night and today I tested it. My battery stayed at fully charged for two hours as I did nothing but check it. Soon as I sent a text message and did a couple of minor things the battery started to fall. in an hour it dropped 15%. I think the software doesn't know how to regulate the cores to shut them down.
[T-Mobile LG G2x] JHaste:
Ok... So when I first purchased my phone on Wednesday, I skipped the initial google setup when i first turned the phone on. I fully charged it and got good use out of the first battery drain, however thursday and friday I had horrible battery life, the thing was sitting there doing nothing and it was draining about 15-20% an hour and God forbid i turn the screen on and actually use the device as well... After that last drain I decided I would try the factory reset so I did so and started the phone with a clean format and an empty battery...

Charged it up fully while I was at work and pulled it off the charger and I have been on the thing with moderate use, about 1 hour 20 minutes of screen on time with wifi on while I have been at home and the thing has almost been going strong for 16 hours since I last unplugged and I still have 28% left of my battery...

I restored all the same apps that I had on the previous build so I am almost certain it is none of those that were causing me grief...

Just thought I would share another success story for the factory reset!
[T-Mobile LG G2x] jimbo831:
I am trying to track what is using my battery but not able to. No apps ever show up on the list of what is using my battery, just WiFi, Cell Standby, Display, and Phone Idle. On my Nexus One other apps would usually be on the list as well. Any thoughts?
[T-Mobile LG G2x] Suprah:
I don't have bad battery life but I will do the htc method previously posted
[T-Mobile LG G2x] baldwinguy77:
I'm wondering if it could have something to do with this tweet from Chris Soyars - "@baldwinguy77 don't trust the battery percentage reported, the battery driver blows"...my phone lists those same things in Battery Use FYI
[T-Mobile LG G2x] DebauchedSloth:
That's...quite some driver...
[T-Mobile LG G2x] Frank29:
I did the factory reset last night, then let the battery die and charged it. Today has been amazing improvement.

About 9.5 hours to get to 50%. I took the pic after streaming Pandora on a train for about an hour. Drained about 20% of my battery.

Can't believe the improvement I saw. You can see the difference compared to yesterday
[T-Mobile LG G2x] Profondo_Rosso:
I agree. I got about 22 hours today, when prior I was getting about 6-9 hours.
[T-Mobile LG G2x] pcchameleon:
After doing this procedure and I have still not done a factory reset, im at 59% with 11 hours in... lots of apps installed and widgets....moderate use...

so i would say it is a noticeable improvement
[T-Mobile LG G2x] blahbot90:
Anyone know the charge time for the phone? I started a little over over an hour ago and I'm already at 64%....

I did the factory reset, haven't tried the HTC method yet.
[T-Mobile LG G2x] vinny123:
is it 4g??

i see that its the 4g which is consuming lots of battery.. can anyone confirm it??
[T-Mobile LG G2x] se1zure31:
I think we need a ROM that will display either 3g or 4g so we actually know when we are on a 4g network instead of what we have right now. I know 4g is in my area but I don't know how often I am actually using it.

I have done a factory reset and completely drained the battery, working on complete drain number 2 now. Hard for me to determine the battery usage though because I play lots of games, texts, internet, phone, etc. But it seems to have lasted all day with pretty heavy usage.

And I have noticed that playing any tegra approved game that battery drain is considerably more than a normal game.
[T-Mobile LG G2x] jlevy73:
It's about 2 hours
[T-Mobile LG G2x] cbbplanet:
idk if it happens to any of you guys but when i drain my phone, i have to do a battery pull in order for my phone to either turn on or show its charging. On top of battery pull, i have to keep replugging in the charger to the phone because sometime, it just won't turn on at all even if i keep the charger connected. I don't think its a loose connection problem since it only happens after i drain it.

G2x Battery

Have had the G2x for about 3 days now and using GO launcher EX from the market. GO launcher has a handy widget called task manager. I also have advanced task manager, each time I send the phone to standby I click one of the two and have gotten around 15 hours from a charge, reasonble usage too, I mean, I have only had it 3 days, so alot of set-up and tinkering. Also what advantages are there to rooting to CM7 as opposed to waiting for TMO's android 2.3? CM's MT3G killed all, if any, performance the MT3G had.
[T-Mobile LG G2x] electric33l:
This actually just happened to me. I thought I might have bricked my phone somehow :D Thankfully, I maintained my sanity and pulled battery. I wonder why it does that? The first time I flatlined my battery, I didn't have to pull it. This was the second time. Curious.
[T-Mobile LG G2x] cbbplanet:
it did that everytime for me, i'm not sure if its because i'm not using the original usb charger or not but highly doubt it. I'll keep using it to see if it keeps happening. I might just return it.

ps. i also notice it only takes about 1.5 hours to charge my phone to 100% from a fully drained battery. should i factory reset my phone?
[T-Mobile LG G2x] jsauce75:
I've been running a system monitor for the last twenty hours trying to diagnose my abysmal battery life and the led notification app was indeed using a ton of resources. Second behind the system.
[T-Mobile LG G2x] wastingoctober:
Thanks for the suggestion. I just froze both logmein processes and am hoping to see an improvement on cell standby usage. My battery life is ok--my phone makes it from 8 to 6 with moderate usage while keeping the screen at 30% most of the day and switching to 2G when battery percentage gets low. I've tried the factory restore and didn't find any noticeable improvement. I haven't conditioned the battery, but I'm most excited about this solution, so I'm going to try and see if I can get cell standby usage below 48% before making any other changes.
[T-Mobile LG G2x] jsauce75:
Well did the factory reset yesterday. I just did a full drain and charge. My battery is at 9% after exactly four hours since it was unplugged at 100%. This is really not good.
[T-Mobile LG G2x] lobsterhead:
I posted this in the "Battery Drain Potential Cause" thread:

I rooted my phone the day after I got it and then began using Juice Defender ("Balanced" profile), SetCPU (drops to 200-400MHz when the screen is off), and Bloat Freezer to freeze "WiFi Calling" and "My Account" among other apps. Before freezing certain apps, I noticed (in ATK) that there were 25+ instances going on.

I've had pretty good battery life, but "cell standby" is always at or above 50%. Also, alogcat shows a constant stream of "gsmdataconnectiontracker."

I installed "Battery Monitor Widget" since reading this thread to get a better idea of what the battery usage looks like for real.
[T-Mobile LG G2x] blahbot90:
I dont know if anyone has posted on this but I just did a factory reset and noticed that the signal is zero bars when connected via wifi. As soon as I disconnect from wifi signal goes up. Any idea why? I haven't gone and disabled wifi calling yet the icon for it is still in the corner because I wanted to see how long the battery lasts without installing any apps or messing with it after reset.

My Battery on Lg g2x

I just wanted to share with you guys also. I to have been dealing with the battery issue. I got my phone on Wednesday the 20th when it came out. It barely had any battery, So as soon as I got to work I put it to charged. After it was fully charged, I started to load all my apps. The battery would not last much, probably about 4hrs before I had to charge it again. So I downloaded the App called Juice Defender! ( I highly recommended to all my Android friends) I enabled it and left it as default on BALANCE. After doing so, my battery lasted way longer then normal, up to 13hrs. The program controls your phone when it goes on standby, it turns off your 3g, 4g. When you enable it, your connection comes back within 2seconds and so on. I told my friend about it and he's been using it on his Vibrant and has had very good results on battery.

Also, yesterday I disabled the Juice Defender, Let my battery die completely till the phone turned off and put the phone to charge. After fully charged, I turned it on to show my brothers. They checked it out for about probably 10mins and the battery was had dropped to about 85%. so I went ahead and turned it off and charged it for another 1hr. Unplugged the phone, The phone read 100% and that was at 9:40PM. I left the phone unplugged overnight, checked it out this morning at 6:50AM and it was only at 75%. At 10:20AM and it still has 47%.

That's with 4g and everything enabled. So far so good. :)
[T-Mobile LG G2x] blahbot90:
Yea factory reset seems to have done the trick, at least for me. I'm at 69% after moderate data usage in 7 hours. Operating on edge, downloaded about 12 MBs worth of apps, which for edge is a lot.

Now just waiting on CM7 or Stock 2.3
[T-Mobile LG G2x] kampf:
After removing the phone from the charger this morning, three hours later and I've only used %8 of the battery.

I had a hard lock and battery pull yesterday, followed by a full charge, partial discharge, then full charge overnight.

I am running the Battery Monitor Widget and it's much better.

Weird, yeah, but I hope it continues to be this good.

T-minus 25 days.
[T-Mobile LG G2x] rsilva_28:
The same thing happened to me yesterday also. To use that Battery Monitor, You need to have the phone Rooted, Right??

My phone just finally died after 17hrs, I will post the pics when the phone charges up again. :) I waited till it totally just died again so now I'm charging it up.
[T-Mobile LG G2x] kampf:
It does not require root.

I don't have mine rooted, and will avoid that if possible. Went 16 months without doing it to my Nexus One and hope that I don't have to with the G2x.

[T-Mobile LG G2x] Lightning Blue:
I'm also having terrible luck with the battery in my G2x.

However, a lot of it is not the fault of my phone, I live in Farmington NM, signal is quite bad here, and on top of that my DSL Router's Wifi is crap, so I think I lose a lot of battery life to poor reception.

Relating to the driver issues however, I have noticed that it gets quite wacky. I was trying to drain the battery dead by playing music while leaving the screen on, it got down to 1% or so, and kept complaining the battery was dead, and kept going for a good 30 minutes after that!

Phone also seems to charge crazy fast with the included charger.
[T-Mobile LG G2x] rsilva_28:
Yeah! The phone takes about 2 hours to charge. It is fast.
[T-Mobile LG G2x] rsilva_28:
Kampf

I also had a Nexus One, Which I sold to buy this one. I had the Nexus One Rooted.

I had downloaded the Battery Monitor Widget yesterday but I dont see any readings. Is there something that needs to be done to the program to make the program work?? I tried something on the program but it told me something about that my device was not rooted or something like that.
[T-Mobile LG G2x] kampf:
I set mine to 1500 for the capacity of the battery and haven't changed much else. Perhaps you got a different app than the one I linked?
[T-Mobile LG G2x] gaww:
Where/how- and with what did you freeze logmein processes?
[T-Mobile LG G2x] player911:
You can just delete it with Root Explorer from /system/app/

or

Use Titanium Backup to freeze

I just deleted it.
[T-Mobile LG G2x] jink25:
Few additional things I have found.

1. I confirmed several times that qik video is a complete piece of junk and drains the battery.

2. In settings-location & security settings DO NOT enable Use GPS satellites unless you really need to use specific GPS data for navigation...when indoors the GPS keeps looking for signal and drains the battery very quick.

3. Bluetooth seems to have an issue and is not power friendly at all...I have mine turn on at scheduled times only using an app.

Other Disclaimers:

As has been posted elsewhere the battery drivers are poor at best, you cannot trust the numbers being reported back. What I can confirm is that the factory reset gave me a useable phone for a lot longer than the 5-6 hrs I started with when the phone would physically turn off....regardless of misreporting battery status. So basically do the reset and keep the offending apps/processes off until a better version comes out, and dont trust the reported battery percentage.

[T-Mobile LG G2x] Zspy1985:
I'm sitting on about 6 hours since 100% fully charged, left the house to go to work using the bluetooth with Rhapsody in offline mode with a total of 3 hours or so it being on

and my battery is at 54%.

Also, using twitter a bit to look at some new posts by Attack of the Show and such. A couple games of Robot Unicore Attack, tried playing Pocket Legands for about 5 minutes and gave up, then add in the 7-8 times I showed off my LauncherPro Plus screen with the Cube setting going back and forth showing off the power of G2X.

Also 1 text I sent to my girlfriend about dinner and checked it and besides that the often check on when my breaks are over.

All in all ....BEST PHONE I HAVE HAD!
