I took mine off charge 12 hours ago and I'm at 49% but I only listened to music for an hour and the npr app for an hour. Bluetooth disabled. wifi sleeps never. the battery reporting is terrible it doesnt actually tell you which apps are using what.
[T-Mobile LG G2x] jsauce75:
What is the explanation for some people having this problem and some not? If it's software shouldn't they all be the same? I know usage varies for everyone, but I haven't gotten more than five hours out of mine on a charge since day one.
[T-Mobile LG G2x] EmceeGeek:
I'm sure that's what it actually gives. No telling with LG, I don't trust them.

[T-Mobile LG G2x] jink25:
The battery is 1500...the battery monitor widget needs to be MANUALLY SET to 1500, default is 1200.
[T-Mobile LG G2x] jink25:
Follow the steps I provided, do a factory reset and dont touch anything else...run the phone completely stock, dont configure anything and see if your issue goes away.

Many people have their phone configured with every service possible running as well as numerous junk programs that drain battery.

If it is still not working after trying that then exchange the phone.

My Battery Update

Yesterday my phone held up for 17hrs before it died completely!

So far after doing what I wrote on my post yesterday, My battery seems to be holding up pretty good. Last night my battery was at around 53% so I put the phone to charge overnight. When I got up this morning, The phone was fully charged.

I went ahead and turned the phone off while plugged in.

Unplugged it and then turned it on.

Checked the battery Status and it was at 100%

I've had the phone on for 2 1/2 hours and is at 87%

I've made a few calls and sent a few text messages. Outlook and Gmail running and emails coming in and 4g running at all times. Will see how it goes throughout the day again.

So Far So Good!!! :D
[T-Mobile LG G2x] mobilehavoc:
I don't get the point of unplugging it fully charged then turning it off and on. What does that do exactly? I get similar battery life and I don't do any of this and I haven't factory reset either. Not sure what's going on.

I also run a ton of crap (I admit it) in the background and keep Wifi and Bluetooth on all the time (as well as GPS). Seems to be fine.
[T-Mobile LG G2x] jbekier:
Seems to have worked

The first night I got my phone, I charged it to 100% and then unplugged it at 1:45am. When I checked the phone the next morning at 8:30am, it was completely dead. I had to plug it back in to get it turned on. I don't know when it died, but best case scenario it died in 6h 45m doing nothing but standby.

That morning, I factory reset, charged to 100%, and now it's been running incredibly. 23 hours later, the battery is at 63%! Admittedly, I only put the phone to light use yesterday (a few phone calls, some browsing, a few minutes of gaming, texts), but if this sticks then I'll be extremely pleased.

Also, I haven't had to do any battery pulls since the factory reset (I had to do it twice the first day).
[T-Mobile LG G2x] jomaxwel:
The thing I don't get is why phone idle is using as much battery as cell standby. They are both using about 43% of my battery use while at work. On my G2 phone idle always used less battery then cell standby. It seams that there is something wrong with the standby mode on the G2X. I don't think it should use that much battery while sitting idle.
[T-Mobile LG G2x] wmm:
It's not. As pointed out in another thread, these numbers are completely bogus. The battery-monitoring software is buggy, and you'll get no useful insight at all into what's really using the power from looking at this display.
[T-Mobile LG G2x] jbekier:
Remember guys, the battery use stats are what percentage each process has used OF DEPLETED BATTERY LIFE, not total battery life. As someone pointed about before, they have to add up to roughly 100% even if you still have 90% battery life left overall. So when you see cell standby using 43%, it's not using 43% of your battery, it has used 43% of that percentage of battery life that you have already used.
[T-Mobile LG G2x] mobilehavoc:
Its weird because a factory reset just deletes user data and apps. This would mean you could achieve the same results just uninstalling apps?
[T-Mobile LG G2x] jbekier:
I don't think so. I had the same apps installed both times (the market automatically downloaded them both times when I signed into my Google account.)

I don't claim to know why it works, but it sure seems to be working. In 45 minutes, I will hit the 24 hour mark. I'm at 57% now.
[T-Mobile LG G2x] aquariumdrinker:
This isn't especially helpful. If the remaining 90% of your battery gets used up like the first 10% (and if Android is reporting the correct numbers), then cell standby will have used 43% of your battery. But there is no need to wait until your phone is completely dead before you start worrying about bad code eating your charge. Under normal use, 43% of power consumed going to cell standby (whatever percentage of the battery remains) is too much.
[T-Mobile LG G2x] jbekier:
True, but it all depends on overall battery life. If it's fine, than who cares how usage breaks down. If it sucks, then you need to figure it why it sucks.

My cell standby % is at 51%, but my battery has now been lasting so long that I have no cause for concern. If one's phone lasts 40 hours based on normal use, I would assume most wouldn't care how processes share the battery.
[T-Mobile LG G2x] mobilehavoc:
Can you post your usage and what's on, off, what apps are running, email accounts,etc? - I find it hard to believe you've used your phone for 24 hours and are just hitting 24 hours. You must not use the phone at all, have nothing syncing and everything turned off.

I had an Incredible with a 2100mah battery before the G2X and even with that, 24 hours of solid use was a stretch.
[T-Mobile LG G2x] jomaxwel:
Those stats are from 5hrs use and 56% battery left with lite use. And was in reference to my past use with Android devices. My point still stands that the use is excessive for what I am doing. I have also done the hard reset and battery calibration. I am a long time android user and the battery life on this device is more like sence powered devices in battery consumption then a vanilla android device. I am averaging 11hrs with my phone and loosing about 10% an hour. Just saying it seams as though there is a larger issue.
[T-Mobile LG G2x] jbekier:
Sure. As I mentioned before, I am a light user. I wouldn't describe this as 24 hours of "solid use" by any means.

I have GPS on, wifi off, bluetooth off, 4g on. I have one gmail account that constantly syncs for calendar/mail/contacts. In the past 24 hours, I have used the phone for light texting, a few phone calls (mostly short calls), reading news using the stock news/weather app, and about 10 minutes of NFS Shift.

Without a doubt, the phone is idle most of the time. I have several downloaded apps, but I don't think any of them are hogs. I use Zeam launcher.

The phone just crossed the 24 hr mark and is at 51%. Part of me is concerned that the battery driver really is messed up, and that 51% is wrong. I'm half expecting it to completely shut down long before hitting 0%, but that wouldn't change the fact that it has been running for 24 hours now. Late yesterday, I plugged the phone into a blackberry charger for about a millisecond just to verify that it would fit, so that screwed up my "time since unplugged" stats, but I've been timing it manually.

I don't blame you for doubting me, but I have no reason to lie. I am still using this phone on a test-run, and up until this current battery run I thought I was going to have to return it. As I mentioned in my first post, when I first got the phone it died within 6h 45m doing NOTHING but sitting idle, and experienced a few lockups. I still fear I may have to return the phone if lockups continue, but I haven't had one since Sunday night.

Also, I'm not the only one reporting fantastic battery life. There are others (not sure if they are on this board, anrdoidforums, or tmobile) who are reporting 30+ hours of usage.

Let me know if you want to know anything else about what's running.
[T-Mobile LG G2x] mobilehavoc:
Don't get me wrong, I don't doubt you can do it - I'm sure you can. I just don't know if I can ever use my phone that little!!! ;)

I just have a charger at work and home. I also just bought an external 5400mah battery pack (size of the phone) that can recharge the phone 3-4 times before it needs a charge.

So I think for now I'm going to continue heavily using it and just recharge as needed. Less headache/restraint needed that way :D
[T-Mobile LG G2x] liquidblue1985:
Mine still looks pretty pathetic... :(
[T-Mobile LG G2x] mumbojumbo01:
Mine is pathetic after doing the factory resets, couple of times of the complete dead to full charge.

I even did the htc method provided.
[T-Mobile LG G2x] jsauce75:
Has anyone just tried swapping the battery out to see if there is a bad batch of batteries, or has that been ruled out. Sometimes it's the simplest explanation.
[T-Mobile LG G2x] jsauce75:
My alogcat just has webkit draw, new webkit draw, new picture message id over and over and over again. What the hell does that mean?
[T-Mobile LG G2x] Profondo_Rosso:
That's exactly like my story, however I do have bad news. I'm now three days since I did the factory reset, and haven't changed anything on the phone. Today, I'm down to 20% after 10 hours with normal use. Yesterday I got about 12 hours. Day before, I got over 20. It's progressively getting worse, which is just about the last thing I wanted to have happen obviously.

Now I'm wondering if I should think about returning it.
[T-Mobile LG G2x] wIIse:
I think I'm about to exchange my phone... been reading this awesome thread and coming from an HTC HEROCDMA, I thought this phone's battery's life was going to be superb! WRONG!!

I have done all suggested and the most I got from a charge is about 15 hours with almost no usage. Once the phone is on, OMG it drains so fast.... say 10% + an hour.

I am now experimenting with Juice Defender to see how much better it gets!

I will give it one more day, if I do not get better results I will return my phone for another one....hmmmmm, which makes me think I would need to unroot! :)
[T-Mobile LG G2x] kampf:
Returned mine.

Quad-band 3G, 2.3, and a battery resolution will make me get another one.
[T-Mobile LG G2x] wIIse:
Which one you are getting?
[T-Mobile LG G2x] donbeth:
Thanks!

Thanks so much for all the advice here. I just got the GX2 on Friday and the battery has been a huge concern for me. Today I had to charge after about 4 hours of casual use. Then it seemed to take a long time to charge.

First thing I learned from ya'll is turn off the GPS! this is my first Android.

Will drain battery and recharge as recommended. Newbie question: when i reset to factory settings does that mean I have to reinstall the apps I added?
[T-Mobile LG G2x] jink25:
If you setup a google account and have it remember your apps then it will reinstall all of them for you....but part of what I suggested with the factory reset is eliminating variables that can cause battery drain before you go nuts installing apps.
[T-Mobile LG G2x] kampf:
I'll get the Sensation and give it a try. EMP plans make it really easy to buy and return phones, and I have a pretty good relationship with two of the local T-Mo store guys, which helps.

The Samsung Galaxy SII looks impressive, but we'll see how soon it'll be available here.

Worst case is I get to try all three and they still don't match the user experience of a stock Nexus One.

I do hope that LG and/or Cyanogen get the battery issue resolved, some updates, and a final say on the quad-band issue.

Battery Update

Here's my Update on my battery

Last night when I was about to get home, my battery was at around 7%. I went ahead and started to charge it. I started charging it at around 7:30PM. at around 10:00PM the phone displayed the message that it was 100% Fully charged. So I said, I'll just leave it plugged in till the morning. I checked the phone in the morning when I got up, went to check it and it was OFF!! I would try to turn it ON and nothing, So I did a battery pull and turned it on. I checked the battery status and it was at 75%. I put it to charge again from about 6:30AM to about 7:50AM that it was 100% Fully charged. I'm beginning to think that this is a Software issue that the software gets confused monitoring the battery or something and it gives out different readings. I dont want to be doing this all the time. I got till next Wednesday to decide if I'll be keeping it or returning it. :confused:
[T-Mobile LG G2x] jink25:
Sounds more like thermal shutdown to prevent damage to the phone/battery.
[T-Mobile LG G2x] rsilva_28:
What does that mean, Thermal Shutdown??
[T-Mobile LG G2x] dagaetch:
When you leave the phone plugged in, there's a small amount of current still coming from the charger, and it builds up heat. The phone's designed to shutdown automatically if it gets too hot, since overheating can do some serious damage.

As for the battery loss, I've often found that if a phone goes to 100, you unplug it for 20 minutes, then plug it back in, it takes a very long time to go back to 100 meaning it wasn't really there earlier. This has been true for every phone I've ever seen, even back to the days of dumbphones.
[T-Mobile LG G2x] jink25:
Batteries and charging systems can sense temperature and charge rate and if either gets too high it will just shut it off to prevent thermal runaway....basically preventing your phone from melting itself.

If the drivers are screwed up I wouldnt doubt if they messed this up too...which in turn could also explain why people are seeing wide swings in battery performace.
[T-Mobile LG G2x] gaww:
I am having pretty decent battery life. earlier, i did get some high consumption incidents - like 40% drain overnight. Last night was only 5% - pretty typical now.

I use SETCPU with default set for 312/1000 and a screen off profile of 216/456. I also use a manual task manager (Advanced task killer - NOT on automatic!) to be sure I do not have anything running in background at night. Android always has things start running again, but this seems eliminate any large battery drainers overnight.

Also, I find leaving it on WiFi with WiFi calling overnight uses far less of the battery then leaving it on the network. If you don't have WiFi at home, then of course this is not an option.

I am looking forward to some OC ROM/s kernels - hopefully with LV versions and governors like smartass and Min/Max. This combination at 1612 OC resulted in better battery life with my MT4G then stock.

What drivers and how can we tell if they're screwed up??
[T-Mobile LG G2x] jeffreynew23:
That's interesting. I am on my second G2x. I am still having issues with the black screen and having to pull my battery out to turn the phone back on. Do you guys think that purchasing a new battery instead of a phone could fix the issue. I also find that when I have a live wall paper, the black screen issue decreases.

Is there an app that will allow the phone to stop charging once it is at 100%?

As always, the input is greatly appreciated.
[T-Mobile LG G2x] jcbofkc:
I do not understand why wifi calling continues to run with wifi off. I thought windows mobile was a pain in the arse at times. Android is making me crazy. There is no logic to it. I have a few more days in my remorse period to return this thing. I hope a true fix is found soon.

I have no use for wifi calling. Is there any issue with just deleting that piece of junk?
[T-Mobile LG G2x] jayohwhy:
i used titanium pro to freeze it, been two days and no issues so far!
[T-Mobile LG G2x] dagaetch:
If you aren't using it, then sure delete it. I think the reason it's 'running' in the background is so that it can detect when you're connected to a wifi network and activate automatically. Not sure if there's a way to change that.
[T-Mobile LG G2x] jbekier:
My phone is STILL running on the charge from Monday. I'm an hour and a half away from hitting 48 hours on a single charge. Instead of making me happy, I'm just becoming concerned. I can't imagine this is sustainable, so I'm beginning to think the battery is just really erratic.

I fear the next few charges won't be so good and I'll have to end up returning the phone. Luckily I'm in CA so I get 30 days, but it's still a shame. I was really excited for this phone and it sure is growing on me...it's so fast and it just plain works.
[T-Mobile LG G2x] jink25:
Hardware prevents over charging the battery, no apps needed...this is nothing new, it is in practically every battery powered device.
[T-Mobile LG G2x] jsauce75:
I have noticed that the standby time on this phone is great. The amount of time I get from using the phone on the other hand is abysmal. So compared to my n1, it will last twice as long with the screen off on a desk, but half as long with the screen on doing anything.l
[T-Mobile LG G2x] jsapp:
I have the same issue. I am on my phone a lot at work. I will be charging with usb while using it, and my battery will still drain, just slower.
[T-Mobile LG G2x] icase81:
It definitely seems to be a software issue. Doing the factory reset wipes the battery driver's history and it starts over from scratch. Once you use and charge it a few times, that's then it starts getting wonky. Can't wait until CM7 is out or the GB patch.
[T-Mobile LG G2x] Profondo_Rosso:
Amen bro. I just hope it's out soon
[T-Mobile LG G2x] donbeth:
Huge Thanks! I know there is much debate on this topic but the original author seemed to help me!

First I let the battery drain and then charged. Battery seemed better but still not able to make it through a business day, and one that had very little talk time.

last night, I drained battery again, charged until I could turn it on, reset to factory and continued charge overnight. First I noticed it charged much faster. So far today it has been running for 4 hours at 64% batter. Running bluetooth, not GPS, and little talk time. Not the best, but way better!
[T-Mobile LG G2x] spencersir2:
If anyone needs instructions on how to get your battery to last for over twenty hours goto the link in my sig I have everything I did and my phone know actually can make it past when I get home at night!
[T-Mobile LG G2x] jink25:
My battery lasts for every bit of 20 hours without rooting, adding a bunch of unnecessary programs and disabling half the stuff that makes it a smartphone.

A sound solution is never to just throw a bunch of apps at something and call it a fix...as a software engineer myself that is about the last thing I would tell someone to do trying to troubleshoot a problem.

Several of the other points are pure speculation and not shown to be valid... has anyone shown TMobile "4G" to use more power than its extremely similar 3G..I see no proof of that. 2G should show some improvement in battery life, but then why own a 4G phone? My Galaxy S 4G doesnt have any issue sitting there idle on full 4G with everything syncing and last for well over 36 hrs, so to say 4G is the issue is misleading.

...I wonder how long the battery will stay charged if I completly turn off the phone...oh wait then its not a very useful device anymore.

The bottom line is there is a software issue that should be addressed in an upcoming release.
[T-Mobile LG G2x] spencersir2:
And I one hundred percent agree, but until that day comes is it wrong for us to try and maximize what we can since, at least me personally, we don't have the knowledge to correct the software itself?
[T-Mobile LG G2x] jink25:
Nothing wront with trying different ways to maximize the battery life and I dont disagree that your approach may in fact get people 20 hours of use.

Although, for me when I get a new device with new fancy features it is not a feasible solution to disable all of them in order to get a usable product.

My point is that before people go to disabling everything and crippling the usability of the phone they need to figure out their root cause of the problem.

Installing additional software to resolve an issue only leads to further complication. For example I laugh everytime I see the PC cleaning programs and registry fixers...almost everytime someone brings me a PC that they tried to fix with one of these ends up worse than what initially caused the problem and just compounds the issue.

So in essence my recommendation is if people are having issues, run the phone as close to stock as possible for a little while by doing a factory reset.

For me a factory reset and getting the phone to where it was before is only a few minute process and re-syncing my google account which gets all my contacts back.
[T-Mobile LG G2x] spencersir2:
But in all honesty isn't that what i did?

1) I REMOVED all the Bloatware that T-mobile gave us(Making me closer to true Vanilla android like my N1)

2)Calibrating is exactly the same as Factory Reset when it comes to the battery

3)Set CPU i use to simply have less going on when the screen is off

4)And all other apps are simply just showing what the phone is doing.
[T-Mobile LG G2x] jink25:
Calibrating the battery is not why the factory reset tends to allievate some of the worst cases of battery drain such as what I was initially experiencing...unfortunately I really havnt had time to dive further into things to figure out what happened, especially since a 2 min factory reset solved the issue for me.

The battery drain issue is getting so convoluted and confused now with many people who are having issues solely due to poor configurations compounded by misreporting battery drivers that make people think their levels are all over the place and draining instantly.

Your above approach is just fine as it can be accomplished without disabling many of the advanced features of the phone and keeping 4g data and syncing going etc...

Unfortunately most users dont know what they are doing (not saying you, as your approach works for you) and end up causing more grief by trying to fix it that way rather than going back to stock and slowly determine where their problems came from.
[T-Mobile LG G2x] nextgin:
You shouldn't have to use Juice Defender to just get a full day from your phone. Something is wrong with it, so go back to your store and get it exchanged. That's the only way LG is going to find out that there is something wrong with one of the installed apps. Cell Standby and Phone Idle shouldn't be using 85% of the batter in 12hrs.
[T-Mobile LG G2x] chk230:
heavy battery drain on cell standby

I'm getting heavy battery drain from "cell standby", almost 50% of battery use is cell standby?

Anybody else had this problem?
[T-Mobile LG G2x] saxon9021:
I was having that same issue I rooted removed bloatware and disabled GPS unless using it also remove Widgets they pull a lot of battery and they aren't really needed minus Google search bar that's a life saver hope it helps
[T-Mobile LG G2x] Sk8trfred:
I think a shorter list would be is anyone not experiencing this. T-mobile says I need a new battery but they don't have any lol. I think my problem is that my phone was shipped with a dead battery and I know that isn't good for them. First phone I can remember getting that wouldn't power on out of the box
[T-Mobile LG G2x] chk230:
mine too, true, really strange
[T-Mobile LG G2x] :
I did the calibration yesterday and it seems to have made a big difference. At 8 hours and 73%. I'll have to see how it changes as I use it through the day.
