This is what I did after numerous charges, drains and factory resets after getting the phone Wednesday:

- Rooted phone

- Installed ClockworkMod

- Did Titanium Backup

- Did Nandroid backup

- Wiped phone

- Installed Eagle's Blood GB 1.0.4

- Charged to 100%

- Ran battery Calibration

- Turned off GPS satellites

Then since this was at 1 AM last night, I let the phone sit idle all night until I took it to work at 10 AM. By 7 PM after texting, making phone calls, using youtube a lot and doing facebook stuff, I was at 15%. I drained it to 2% and then put it on the charger where it is now.

Did I miss anything in this process or is it just more charge cycling? What does "then 2 X top up with it off, followed by another full charge overnight with it on" mean? Am I supposed to be charging with it on? I'm turning it off each time.

Edit: Ack, I picked up the charge 3 hours in and it's at 67%. Why does it take so long is it really meant to be left overnight? This was left off charging.

I have done everything in this thread. I have even charged the battery to 100% using a universal charger for cell batteries. The battery did not get hot. As soon as I put the battery back in the phone turned on and told me I had only 54%. I am running the cm7 nightlies btw. I have tried power cycles several times. Even after the phone said 54% I rebooted when it dropped to 43% and the phone wouldn't reboot on its own. When it finally turned on from me powering it on, the new % was 4! If I leave the battery in the phone overnight and charge it grows to maybe 88%, but that's it. And it won't stay on while charging. It will eventually turn itself off and I have to power it back on in the morning. I was having the same problems before root and cm7. Battery wipes does nothing. Any wipe for that matter. I want this phone to work so bad. Also, I have tried running the phone in airplane mode for all my trials, and it won't charge past 45% while screen is on. Phone gets very hot, not just warm. This is not normal behavior. Congrats to you if you don't have this problem. I have not gotten a full hour of use from this phone. I hope it is just a battery issue that I can replace. If it was software I assume it would have been fixed after everything I have tried. I want someone to post that has had the exact same problem and has found a fix. Oh, and I have put a sim card in only once. It did not change the battery life with it in or out. Same results. Just to say again, I have tried everything in this thread, no steps skipped. I would love to be able to use this great phone. And I hope this helps for a diagnosis. :(

Mine is dying each day before 8 pm. Im about to lose it now. Been using web, txting, bluetooth headset. This is crazy.
[T-Mobile LG G2x] Erislover:
This is awesome info! I'm going to repost as a thread...let me know if you want me to remove it.
[T-Mobile LG G2x] j2eubank:
My battery story is just strange. I never had real battery issues. When I first got the phone on stock ROM it definitely wasn't great but not horrible, I could get 8 or 9 hours of normal use before feeling like it needed plugged in. I have had several android phones on several roms and experienced battery life like that time to time and I think the stock froyo rom was pretty bad all the way around.

I moved onto CM nightlies right away and honestly the battery was way better and was not at all an issue for me. That is until last Friday. All the sudden after an update to whatever # nightly it was for 5/20 and boom.. my phone went nuts. with regular use I lost my entire charge in about 3hrs, phone was warm on back near the top. So I wiped, dalvik, and formatted /system and reflashed and the same thing happened.

At this point I have tried a few more full wipes, a couple nandroid restores of CM going back to the beginning of May and still have the same issue. Last night I fully recovered my very first CM build after a wipe, system format and dalvik wipe. The phone seemed less warm but the battery would spike up on mA from time to time. I left it on overnight and it died in 6hrs idle.

Now I know the battery driver issues and have experienced those issues as well.. if I ever reboot my phone comes back at a much lower level but what I'm experiencing now is totally different.

So for now I'm back on my N1 and charging this dang thing again (this phone is on my charger now more often than not) and will restore my stock nandroid and see if that helps. I'm running out of ideas at this point.
[T-Mobile LG G2x] raz1337:
Left house this morning at 9 at full. Been texing, going on net, using bluetooth in car and watching youtube. Im at 27% at 1 pm wtf. Another guy says to buy extra batts but why should i have to.
[T-Mobile LG G2x] regP:
the screen and 3g radio are the biggest battery drain on smartphones. web browsing and YouTube use both of these. you cant use your phone as a computer and expect it to last 24 hours. what is your screen on time?
[T-Mobile LG G2x] raz1337:
What do you mean by screen on time? I understand the phone can't be used as a computer, but I just find it odd after switching from a touch pro 2 that handled making it through the day without going kaput halfway through. It's not like I don't understand that a variety of smart phone apps are battery hogs, but when I've had better performance with other phones, I expect more. I'm willing to accept that it's just "it's a new phone so it'll take time for drivers to optimize."
[T-Mobile LG G2x] regP:
touch pro runs a 528mhz cpu, a different operating system, and I'm betting a less powerful HSPA radio. cant expect a phone with completely different hardware and software to perform the same in any department. that includes battery life.

settings -> about phone -> battery use -> click display.
[T-Mobile LG G2x] Deth Becomes You:
Thanks for the response TWiiTCH :)

I have done absolutely all combos and roms and kernels. I really think it is the battery. After that post I originally made I had the battery on its own charger and it charged for ~7 hrs until it was 100%. I pulled the battery and plugged it back into the charger and it started charging again as if it were fully drained. I took it off the charger again after another 8 hours and put it in the phone. It started up and had a 32% battery charge. After the battery hit 30% the phone shut off. So, and this is why I believe it is the battery, the phone was completely off and the the battery slowly got hotter and hotter. That means the battery was trying to discharge and there was no reason to. The phone was OFF. I ordered a battery that will be here in a day or so and I will repost my results. It seems that those who replaced their battery got the phone to work properly. I am hoping for the same results. My first LG device and I am disappointed. But if the battery works then I will just blame the battery manufacturers that supplied the OG ones inside the G2x. Here's to hopin' :rolleyes:
[T-Mobile LG G2x] j2eubank:
so while running the n1 today I had the sim out of mine and in airplane mode.. battery was just fine holding around 81% (never charges past 91%) after 3.5hrs. Back wasn't warm at all everything seemed good. I powered off, popped the sim back in, powered back on and battery @ 24% phones warm again.

Not exactly unexpected but interesting none the less. (and lame :cool: )
[T-Mobile LG G2x] Horsey:
I left the phone on with very minimal usage for about 13 hours and only ~25 percent battery usage until the phone rebooted itself then the phone used about 25 percent the next two hours with very light use.
[T-Mobile LG G2x] raz1337:
2 hours 20 minutes out of 7.5 hrs on battery
[T-Mobile LG G2x] regP:
that's pretty standard. the longest I've gotten was. a little over 3 hours. I ask because screen on time pretty much represents actual phone usage not idle time. your battery life is fine. if you want longer life you'll have to use the phone less, plug it in, or buy spare batteries.
[T-Mobile LG G2x] raz1337:
So, basically, I traded more more phone function for more battery usage?
[T-Mobile LG G2x] rauelius:
I don't know how, but recently my battery has been pretty darn good! Beating my Nexus One! I accidently did a system restore on my G2X after completely draining the battery. The phone stopped booting so I used a battery for an Optimus 2X I got off ebay. That turned on the phone but that battery was dead too. I left the Optimum 2X battery in the phone and let it charge overnight. By morning the phone was wicked hot to the touch. Thinking I ruined the phone I turned it on and it had a full battery. That day I pulled it off the charger at 2pm and when I got home at 1am I still had 43% left, I was very pleased. Today I charged both my Nexus One and G2x and pulled them off at the same time and ran them against each other today. Finally tally at this time is:

Nexus One: 56%

G2x: 58%

I installed Battery Monitor and Cpu Monitor on both and have been keeping an eye on that. The G2x seems to use less power than the Nexus One from the readings.

Also the Original G2X battery is working fine too now, infact that's the battery I'm testing today, the Optimus 2X battery is in my wallet incase that battery wanted to give up. Glad I didn't need it.
[T-Mobile LG G2x] rauelius:
I ordered three Optimus 2x batteries off of ebay, very well priced and if the once I received is anything to go by definitely the real thing, check it out:

http://cgi.ebay.com/New-3x-1500Mah-...118203?pt=PDA_Accessories&hash=item5199594ffb
[T-Mobile LG G2x] oOo B0XeR oOo:
Yep exactly... I did the same thing. That way if I'm gonna go out somewhere important and dont want to worry about my battery I'll pre-charge 2 of them and go. Or if I'm traveling overnight somewhere etc.. It's not much money and once they fix it (if they do) I'll just sell these back on ebay for like $3 or something.
[T-Mobile LG G2x] j2eubank:
Well, pretty sure mines the battery. I wiped again last night, changed to eagles blood and finally got a charge all the way to 100%. I needed my phone this morning so I powered it off overnight. When I woke up the phone was completely dead, 100% - 0% in 6hrs while turned off. The battery can't hold a charge even when not in use at all.

I called tmo this morning and they are mailing out a new battery. I also placed an order from eBay as well.

Hopefully it's the battery only.
[T-Mobile LG G2x] Deth Becomes You:
TWiiTCH,

And that's what I want! :) The reason I have this phone and any other Android os phone is to use it's abilities. What would be the point of having all that tech in your hand and reduce all the features so you are basically running iOS? You wouldn't. You would use it to its fullest potential. I want the G2x to work like it's supposed to. I believe getting the new battery will help, plus the change in the update if they would finally release it. St00pid Tmo/LG red tape. Now we play the waiting game...
[T-Mobile LG G2x] Deth Becomes You:
j2eubank, please update your success or fail with the new battery when you get it. Thanks :)
[T-Mobile LG G2x] j2eubank:
Definitely will. If your having the issues like I was (too warm while unplugged, way warm while on the charger and excessive drain, mine would die in 3-6hrs) then I would try and charge it all the way up and turn it off overnight and see what it looks like in the morning. If it can't hold a charge while the phone is powered off it's definitely the battery. I guess there is the possibility that the phone killed the battery but we'll see on that.

My battery was fine for almost a month... this came on really quick last friday for me.
[T-Mobile LG G2x] Deth Becomes You:
Yeah it has got to be the battery now. If it wasn't originally it is now. The battery heats up even when the phone is off. On a universal charger the battery will charge fully and drain on its own quickly without even being plugged in. :-/ I am getting a new battery today or tomorrow. I will post with my results after the new battery. Thanks for your response.
[T-Mobile LG G2x] raz1337:
What doss the blinking target icon in the top bar mean?

Still trying to be more conservative and use video and bluetooth less and still 25% in 6 hrs. I gotta figure how to get through a day without charging till bedtime.
[T-Mobile LG G2x] j2eubank:
That's GPS assuming you're on gingerbread.
[T-Mobile LG G2x] raz1337:
Okay. I tried going through and killing each service, but should I be using a third party program for it?

What are other apps I could use to monitor the battery, cpu, etc on the phone? The battery widget pro looks cool, but is there something just as good that's free?

I charged to full, then ran calibration, used it until it went empty, charged to full while on, let it sit all night, and it was at 80%. I charged to 100% before leaving the house at 12 PM and it was dead by 6:30 PM.

I guess I'll look into a screenshot app also.
[T-Mobile LG G2x] regP:
what was your screen on time during those 6.5 hours?
[T-Mobile LG G2x] raz1337:
I lost it, phone got turned off. I should be recording this.
[T-Mobile LG G2x] j2eubank:
just remember that its been stated many times that the battery driver is very bad.. its being worked on by cm a probably many others. meaning you probably can't trust what the phone is telling you.
[T-Mobile LG G2x] oOo B0XeR oOo:
So this is a great factor to bring up. BTW, you know the phone has a built-in screenshot feature right? Simultaneously press "power" and "home" light key. If you hit them together you'll here it clack... files will be saved into your Gallery > Captured Images folder.

Anyway, the app thing is a very real issue. I've noticed that 3 and 4 apps that I have had all do the exact same thing... and I think thsis is a common trait amongst a lot of these "home cooked" apps. The Dev just adds one or two features and before you know it you have 7 differnet battery monitors running crushing the battery. I'm not a fan of excessively weird battery monitors and task-killers and auto-gps/wifi off etc... These just all run and jamb things up and consume power. Truth is, for most, if I sent you an extremely detailed log of battery performacne and health... and you were able to calculate percentatges and usage........ what are you going to do now that you know the numbers? Nothing right? haha What else can you kill and so forth... if youre going through that kind of trouble just turn your phone off, keep it in your pocket and when its time to call just use it. Thats how you save battery! ;)

Wrapping up here, I have noticed that after installing any Example app everything may work but the OS is processing slow and extrememly cached out and sluggish. I started FC'ing the app & Uninstall the app, reboot if needed, and then check it out, you can download again even if you purchased it. I found several apps although they seem compatlble are just leaching. I only use 3rd party apps for like the off-label stuff like mod'ing and testing etc.. As far as the system goes, if you install Extended Controls you'll have an a nice widget to use the regular system controls from your homepage (mine has a UI applied to the GB 2.3 OS but you get the idea. You gotta be rooted obviously and SU applied the Extended Controls and as as Device Admin permissions. The shots i took show screen by screen (I live in these screens, not sure about others). Use as much onboard equipment as you can.
[T-Mobile LG G2x] j2eubank:
Well...got my battery today. Got home, charged to 100% in about 1.5hrs. Unplugged and left it pretty much alone. 2.5hrs later and 50% of the battery is gone. I turned it off completely again so we'll see if it holds overnight. Not looking promising... I'll test it over the weekend but if it doesn't perform better then it has to be the phone...
[T-Mobile LG G2x] donbeth:
Thanks for that tip on the screen capture! Worked perfectly.

I have been monitoring this thread and trying out tips here and there. The battery is getting worse. Less than a month on the phone. This morning fully charged at 100%. Drove to office with phone plugged in to car charger while I made 2 calls. Since at the office, no calls, very little use of the phone and now sitting at about 2.5 hours since it was charged I am down to 76% of battery. Blue tooth is on, WIFI off, GPS off.
[T-Mobile LG G2x] j2eubank:
ok.. just to report back. I completely powered the phone off last night with the new battery in @ about 50%. woke up this morning tried to power it on and the battery was beyond dead. something is wrong with the phone itself. called tmobile this morning and they are sending me a new one..

back to my n1 for now.
[T-Mobile LG G2x] camelflage:
I am on the stock rom, rooted, uninstalled my account. I have done almost all the battery drain fixes (battery cycle/optimizer, turn off wifi/data/sync for majority of the day, low screen brightness - less than the low setting on the power control widget) and taking my phone off the charger at 7am, it will last to 10pm with about 10% left. The only problem is I do not want to have to shut down all services for the entire day just to barely make it through the day with 1-2 calls @ 5min each, 50 texts, and light web browsing on wifi when I turn it on. Am I asking for too much on this phone? Anyone have success with switching the battery out?
[T-Mobile LG G2x] tackleberry:
its 1515, i removed phone at 0800. so thats 7 hours, 15 min on battery, and sitting at 38%. made a 25 min phone call, sent about 10 sms, and about 15 google talk messages or so, played with facebook and made about 20 or so posts, checked XDA about 20 times, downloaded an app, played with some ringtones and settings. GPS was on standby the whole day until about 1400hrs. wifi was also on almost all the time, performed 3 reboots.

its the first day after flashing new rom late last night.

33% is cell standby

33% is wifi

28% is phone idle

7% is display.

it did say earlier that 2% was from simi clock, but thats no longer there.

my battery did run up to almost 105 degrees, and not sure if thats too hot or not, but it was hotter than my overclocked G2 ever got.
[T-Mobile LG G2x] raz1337:
Well, I left the house this morning at 8:45 like always with 100%. I work in a dept store and I tend to use my phone for texting or random web browsing, or using facebook app during the day. During lunch, I turned on bluetooth on my headset and listened to music and installed a weatherbug app. It didn't work well. It was around 50% battery at 2 PM. I continued to text through the day and left work at 6 PM at 15-20%. I played a few youtube videos for a friend, made a few phone calls, played a trailer for a show on a website, and now at 8 PM, it's at 2%.

Personally I think that's light usage of my phone through a typical day. I had to intentionally avoid Youtube on my lunch because I knew my battery would continue draining throughout the day. I get the whole, "don't use your phone as a computer" thing but I expect more.
[T-Mobile LG G2x] tackleberry:
now its 1730 hrs and im at 17%. since then tho i was using the phone a lot looking at xda CM7 threads, a few texts, and 2 phone calls.
[T-Mobile LG G2x] donbeth:
I stopped by the T-Mobile store today and complained about the battery. Showed the guy that it was at 26% at 4:30 pm. He gave me a new battery, no discussion, just pulled it from a boxed phone and swapped my battery!. Will see what happens now.
[T-Mobile LG G2x] tackleberry:
i may do the same, i noticed that my battery has a mid april build date, but my device has a may 9th build date. wondering if they swapped it for someone else. i pretty sure tho my box was still sealed when she brought it out from the back
[T-Mobile LG G2x] raz1337:
Here's my battery usage graph for the last day:

Just to double check....is advanced task killer worth using or should I avoid it?
[T-Mobile LG G2x] oOo B0XeR oOo:
The battery issue is NOT going to go away until a new kernel for the 2.2.2 stock ROM is developed (if ever). My feelings are a new kernel will be released under the 2.3 GB update (either packaged or shortly after official push). In some cases, just like anything, you may have a faulty phone or battery... that's different and unrelated to mass issue.

There is no set of magical combinations that will suddenly make the battery amazing. As I've voiced a few times, I don't believe in shutting down services such as wifi. I use wifi calling at home because my cell reception is terrible at best. The only service I do disable is Bluetooth and thats just because I only use it once every few days... otherwise I'd leave it enabled. Its clear that the issue is global and I too take it off the charger when I leave the house and by 3pm I have a silly amount of battery left and thats not using the phone for any voice and light data... we all know that its unnacceptable. The determining factor is "are you going to deal with it and wait it out or return the phone". Just to be clear, there is no remedy for this issue right now, all these tips are just damage control and trying to make the best out of a rediculous situation.

The kernel HAS to be updated in order to even have a shot at fixing this... or it has to be altered by a 3rd party Dev. The kernel is the manager of resource allocation right, it prioritizes cpu time and dictates the process between hardware and software interaction... thats where the problem is stemming from. That is why so many people are flashing so many ROMs already... this one is just not good. I've been tracking those and it seems like Bionix, Eaglesblood and the newly updated CM7 are the most stable thus far... and all have matching kernels to OC and UV. So if thats what you want to do for now then track on some of those threads. Otherwise you can either install the 2.3 GB Leak or just wait it out. The 2.3 doesn't fix the battery because its ROM only, no new kernel but it is stable aside from a laggy keyboard (pop-up OFF helps) and a few minor quirks... thats what I'm running but I think I'm going to hop on the EaglesBlood or Bionix train now since Trinity kernel looking legit. All of those ROMs and Kernels can be found HERE at the G2X Dev entry pages... just be sure READ carefully and do your homework if you're thinking about flashing one of these ROMs/Kerns... a mismatch WILL brick your phone. And ALWAYS be sure to backup ROM+Apps first and I always move it to my SD then pull a copy onto my PC.

-raz- to answer your question I dont think appkillers are good nor do they help much at all, you can manage this manually but will need to checkmark some additional options if you reboot a lot (to save manually doing it everytime). THe choice is yours though and if you personally see improvement without the loss of fuctionality than it makes sense right? I haven't seen it yet and THIS article is a good supporting doc (props to NikolaiT for that link).

one more...

Oh, also wanted to point out these services DO consume a lot of resources/power as you can see on your device (screenshot below), but what are you gonna do, something is obviously using that power and I need it. As you can see its shows the 'up' time and yes thats the whole screen, no calls 2hrs standby and at 75%. This is native on the G2x... go to Settings > About Phone (very bottom) > Battery Use... fyi.
