This is just a couple of things I noticed about the G2X you might find useful.
1. When running multiple apps while charging you can still get a battery drain. When I was driving the other day I had the phone charging while using the GPS and listening to a show on Beyond Pod. When I arrived at my destination an hour later my G2X used over 10% of battery and was very warm to the touch. (This is not the first Android phone I've owned that has done this.)
2. The day I bought my G2X I dove in head first tinkering. I ended up loading the software from the Optimus. Now that I had it on I installed a kernel that would overclock to 1.4GHZ. The processor on the G2X really came alive. The one thing I noticed was my quadrant scores were great! Then I plugged the phone in to charge. While it was charging I ran quadrant again. This time my numbers were even higher. I was pushing scores close to 4000! The nVidia processor in the G2X is a power hungry beast (in a good way).
I hope this helps the smart ones out there who are going to start pumping out the roms for us.

Different car chargers provide different amounts of current. Some only put out 500 mA, which is definitely not enough for a phone that's running GPS and the display and streaming over wireless. I have one that is rated at 1A (1000 mA) and it was almost able to keep up with my Nexus One's power demands (I don't have enough experience yet with the G2x to know how it fares). My general practice when running GPS and streaming Pandora, which I usually do on trips, is to turn off the display when I have more than a few minutes of a straight shot ("stay on Interstate 95 for 59 miles"); the Nexus One was definitely able to charge on my 1A adapter with the screen off, even running GPS and Pandora, and since Google Navigation gave me a heads-up a couple of miles before the next exit or whatever, I had plenty of time to turn the display back on to see the road configuration, etc.
With respect to heating, that's not uncommon either, especially if the phone mount is exposed to sunshine. My mount has hooks for attaching it to a ventilation grill (I normally use it with a suction cup on the windshield), and I think I'm probably going to use that when driving during the day in the summer; the A/C flow should keep it cool enough, I imagine.

On #1. I had GPS on and was also on the phone a lot at the same time. It held its charge + maybe a few percent charge. I was using a self contained GPS map though, so it did not have to constantly update the map.
On #2. - You did what - did your phone still work? Thought those ROM's had different baseband settings, so were not supposed to work on the G2X (unless Paul has tweaked one already).
Can the kernel be flashed on the G2X stock ROM, or only on the O2x ROM?
Am hoping to see a 2.4 ROM down the road. Everyone is focusing on 3.0, but it is not optimized for dual core - only 2.4 and 3.1 are.

You have an OC kernel working successfully on the G2x???
Waa? You flashed an OC kernel for the 2x?
My thoughts exactly ^^^^^^^^^
Please share the link. Does the phone portion function properly? I thought O2x kernels would screw up our cell radios
Out of everything the OP said, the OC kernal was the only thing important it seems lol.
Not charging + on a car charger is normal. Same as with computer USB charging. If your doing something intensive on the phone such as wireless tether / GPS + stream data + using voice minutes then wall charger is needed. This is almost common sense.
+1 for OverClock kernel information.
Little skeptical of the OP claims about overclocking. The baseband should get messed up unless there were some changes made today or late last night.

Mine does it randomly. I had it since April 20, and it has shutdown 3 or 4 times. Still don't know the cause of it.

Funny no one is stating their OS they are running?
The only time my phone randomly SHUT DOWN was running the leaked Gingerbread rom from LG. Stock was fine as were CM7.
Of all the roms I've tried, I've never had reboot problems or finding the phone off outside of the leaked GB.
This happened to me all the time with the stock FroYo ROM. I think it is caused when the phone runs out of free RAM (due to playing a game or running lots of widgets) I flashed CM7 with the ext4 Trinity maxmem firmware and it fixed all of these types of problems. Also, the stock battery seems to have major issues because when I replaced the battery with a third party one it fixed lots of problems with battery life and also the HDMI instantly drain the battery.
I still believe it could be a combo of questionable batteries and chargers. Purchased two the first week out. Mine started the reboot dance the first night. My wifes phone has had zero issues as has my replacement.
Probable fix
Hello,
So we’ve been working on this issue for quite a while. And have come up with a semi-practical solution. This might interest some of you, who have this issue.
Issue:
Both I and my friend opted out to purchase the new and wonderful LG g2x phone. After receiving the phones we came against a very similar issue. The cellphone unit would shutdown/turnoff during the charge [car or wall]. The shutdown would occur around 95% of battery charge. In addition the phone would get hot. After the shutdown to start the phone would require pulling the battery out of the unit and reconnecting it again, otherwise known as: Perform a battery pull.
Trials:
So after doing some research and funding out that LG is literally doing nothing about this issue, [great testament to their corporate integrity] we decided to take on this issue. At first we also believed that it is, indeed, the battery that gets heated and goes offline after reaching some temperature. After recognizing the poor quality of the battery, I’ve decided to purchase a better quality one online. No surprise really the phone would still lockup at 95% charge.
At this point I took it upon myself to resolve this issue with what resources I have available. I am an MIT student and have a high tech engineering lab available at my disposal, in addition to some free time with a winter break and all. Anyways, I pulled the phone apart and this is what I’ve discovered…
Discovery:
So inside the phone right next to the 4 connecting diodes that connect the battery to the cellphone unit are 2 semis [semiconductor hubs] that are responsible for providing battery charge information to the cellphones cpu [central processing unit] in addition theres also a line running to those semis that probably carries some sort of information [current] that the semis are also responsible for.
The first approach that we took was through the hardware, and killed that additional line and allowed the semis to only be responsible for the battery charge. The results were somewhat positive. Although the phone would freeze and glitch like crazy it would not shutdown with a subsequent necessity of pulling the battery.
We also noticed that it was the two semis that would get hot actually and lockup shutting the phone up and requiring a battery pull. The reason you need to pull the battery is because the iodes would overheat and completely glitch out, also even though the phone was now powered off there still was a current running between the battery and the phone. Only the battery pull would allow the diodes to drop the charge and reset to the position for the phone to be functional again and able to power up.
Solution:
So the idea was to find a software solution, which would free up this one line running into semis and allow them only to carry the responsibility for reporting the battery charge to the cpu. Believe it or not the first thing that came to my mind was the solution.
The app called Advance Task Killer (ATK) [available free on the market] proved to be useful. I do understand that this program is not very effective and only kills running progs in the foreground. However, that single line is also not very important to information transfer and becomes useless after you clear the cellphone’s foreground information transfer.
Basically when you run atk the line becomes inactive and you can charge the phone without any lockups. I’ve been doing that for about 10 days now. Discharging the battery to about 17% and charging it all the way up again and the phone has not yet turned off once and required a battery pull, nor has it been getting hot.
The idea is to clear the line prior to putting the phone on charge [car or wall]. So what you do is run atk few times [twice at least] then plug the phone in. this worked for both me and my boi here @ mit. After a week plus of testing we decided to release this onto the public.
We both a running stock lg g2x gingerbreads and have not tested it on any other roms, however, I suspect that it will have a similar effect on more leaner and cleaner roms like CS7.
Hope this helps those who are still struggling with this issue.
P.S.
In addition I would like to add that we did pull the battery apart in the lab and found that the stock battery was complete SHAYT! Some of the cells were cracked and overall it was just poorly manufactures. Cracked cells inside the power unit diminish its capacity to carry charge by a factor razed to n^power. Also may cause the battery to heat up during the final stages of its charge process [around 95%] due to the fact that to go the last 5% it will require higher resistance also in n^power. I suspect that in this great economy LG is cutting corners whatever place it can so there’s prolly very minimal quality control in power unit production. To those who think that they lose charge too quickly, that the battery gets too hot during charges, and possibly causing the phone to lock up: If you are using the stock battery, you may want to consider replacing it.
P.P.S.
Overall it is a hardware issue, in our opinion, that could be fixed with the use of the software, by rendering that extra line inactive for example. However, I would like to NOT compliment LG as a corporation and organization in general on their moral standing and responsibility that they carry to their customer base by doing completely nothing about this issue!
Thank You LG, I am no longer your customer.

Mine used to only shut down during phone calls. This only happened about 4 or 5 times and it got very annoying but eventually it just stopped and hasn't happened since.

I had my phone reboot during calls a few times a day after I got it. I OC'd my phone with Setcpu and was running Juicedefender. Ever since I clocked it back down and uninstalled those two apps (mind you I just got rid of them without doing any research if it was a problem really either of them cause). I'm going to get replacement batteries soon in hopes to help but it's good know a technique finally so my phone wont crap out during the night.
Seperate story kinda, I once put my phone on the charger. I placed the phone on my bed but with proper air circulation. It sat there for an hour or so. I walked over to use it and the thing was extremely hot. I pulled the battery and checked the phone. The battery was hotter then the phone so you could tell it was the thing over heating and not the phone. I put the battery back in the phone and booted and went straight to spare part's battery stats. It said the battery was overheating. So I pulled the battery and held it and the phone in front of a fan. 5 minutes later it was running cooler then any other time I looked at the battery readings (about 28c) and my phone charged fine for the rest of the night. Also yes when it did over heat the phone wouldn't turn on the first time I got to it.
Hey guys,
This last week has been absolutely brutal in the northeast us. We've had high 90s pretty much everyday. [Especially in the car] my g2x has been suffering from "random reboots" running fauxs 1.2.8 and kernel 0.3.2. It was a new phenomenon, I thought it was the DS kernel I had rather than CM7, but all that did was affect battery life.
I finally was using my device when it decided to "turn off" and the screen just kept turning off ( less and less time being on, fractions of seconds.) Then it just stays off and the battery temp reads 100+° at turn offs.
It requires a battery pull to turn back on ( and I guess turn off) but the heat doesn't seem to come from the battery, but behind the camera, im thinking processor.
Could it be from the OC/UV kernel. I had on? It's on standard now.
Sent from my LG-P999 using XDA App
OC'ing can easily overheat/fry the processor (hence why there's always large warnings around it), especially if the kernel hits a race condition or similar.
The phones are passively cooled. and the radios in the phone heat up the phone when used heavily. I have not had anyphone that didnt get extrememly hot while it is using the radio when its in above 80 degrees ambient temperature and overclocking would just add to this. luckily most have a feature ot turn off the phone at a certain temp to protect the hardware. But I dont think this is a specific g2x problme my old droid does the same thing.
I took mine to a pool in Vegas. It was probably about 90 degrees. I had it under my lounge chair shaded listening to music. It had a heat stroke after about an hour.
I understand why/how overheating can be caused by oc but honestly if its not running at stock (or benchmarking) I have it set to 800mhz by default- its still fast as hell. It hasn't overheated in the last few days, but the problem was that even if I don't use it, it'll overheat.
I use juice defender to keep my radio off when the screens off, so I can't even lay blame to that.
I haven't really dove into undervolting, but in theory wouldn't lower voltage equate to less residual heating?
Sent from my LG-P999 using XDA App
mine does this running stock. Mostly when I have the charger plugged in and am still doing something. It will be taking a charge but the batery level will still slowly fall, once it gets below a certain point it gets really hot behind the camera and the screen starts locking and unlocking. faster and faster until you finally have to pull the battery and let it cool down a while.
YES!!!! I have 2 G2x that do this, and a guy at work has one. All stock phones, and can be doing NOTHING - gets hot near the camera lens, and LOCKS!!!! Have to pull the battery. I pull the battery for 1 second, re-install, and G2x works fine. I know of 3 G2x, and all do this. I can't believe I don't see more of this on this forum. T-Mobile has a "discussion number" on this: 265747. LG claims ignorance. I'd love to know how to "fix" this. I'd also like to know if GB fixes this.
The occasional re-boots are live-able - this lock up is NOT.

I can verify this is an issue with my phone as well! It was happening all the damn time in both stock Froyo and EaglesBlood Froyo, but as soon as I went to CyanogenMod 7 RC1, I haven't had it happen once.
And to those of you who haven't had this happen, it's like the Sleep of Death + your phone gets REALLY hot by the camera lens and it keeps draining the battery and putting out TONS of heat until you do a battery pull. It brought my battery from 100% to 25% in like 30 minutes of doing this.
But CM7 seemed to solve the issue. No more SOD+heat!
This problem has been driving me absolutely insane. My wife and I both got g2x's at the dame time (new from tmobile), and hers rarely does this, while mine does it continually. I was wondering if it was related to the case we have - but we both have the same case - the speck one sold at tmobile.
My wife and I both have the little rubber buggy baby bumper condom case thing that does cover the back - that would reduce heat dissipation. I often carry mine in a belt case that came with the phone from CostCo - she almost never uses that case.
I am getting tired of having my phone getting hot every time I use it for more than 5 minutes... You charge it - it is hot, you use it - it is hot, you lock the screen and put in in the pocket with some apps running to it - it gets hot. The only way to keep it at a normal temperatures, do not use it at all....
I originally blamed it on 4G LTE - so i forced it to 3G for a week without any success... Since it does not heat up on during phone conversations, my theory is that it has to do either with the processor or possibly the battery, that overheats during charge/discharge...
Coming from Fascinate - this has never been an issue to me which makes me miss it a lot ....
I have two of 2 weeks old Charges (brand new ones that I unwrapped myself). It tells me that this is not an isolated issue with particular phone or a battery. I experienced it on a full stock and voodoo kernel.
To all guru's that are out there - did you find any solution to a "hot potato" Charge?

Still could be bad hardware. The only time my Charge gets hot is when it is on the 1amp charger or if I leave the screen on for a very long time. Like 40 minutes or more.
Other than that mine is cool all the time, 4G or 3G

mine doesn't get CRAZY hot but here's how you can fix it, flash the OTB kernel and underlock/volt to 800mhz, the only thing that will slow down is your browser when playing videos(like youtube) through it. It will solve your heat problems, it definitely solved mine for the 2 weeks that i was underclocked.
I've gone to using my spare xperia x10 mini pro now cause I've found while i'm out an about with my sidekick it will randomly get really hot an I don't mean like kinda hot i mean like feels like someone poured a cup of hot coffee onto thigh! The device hasn't been abused or dropped an its always had a tendency of getting warm at random it seams on all firmware versions. The only thing I can think of is possibly a issue with the phone connecting an unconnected often with the Bluetooth in my kia soul.
Now before you ask why I'm bringing this up now I had a none android samsung memoir befor this phone an it would get warm while GPS was enabled. Though in the sidekicks case it does it no matter what things are enabled or disabled x.x
So anyone else notice thier sidekick getting warm? with mine it seams like its something in the actual phone getting hot that in turn heats the battery up cause its around the DEL key on the keyboard.
are you running a 1.2 ghz kernel?
are their any wifi connections/bluetooth connections or any data transfer in the background that could cause your phone to clock itself @1ghz or above?
do you have any apps that run in the background (beyond the stock rom) while you are not using your phone?
your cpu could just be getting hot from background app usage while running @ the max cpu clock speed or overclock speed if you're on a overclock kernel.
The phone has never been overclocked an its done it totaly box stock with no wifi,gps,bluetooth activated an no data being used an has done this aswell with any connections enabled or doing transfers over blue tooth though since day one i do get a FC buzz when it first starts up but doens't say whats FC'd also notice when its getting hot that the battery amount is getting discharged by 10/20%
Hopefully it never got overcharged, or undercharged...
Have you ever turned it on after it turned off from 0% batt (or done this multiple times), I know that Lithium Ion batts have issues (I think it is 15% on the battery, but as 0% to the phone) if they go below 15% (0% in the meter) they will loose the ability to work correctly from then on out...
Calibration ever done at "NOT 100%", so it might think that 100% is 90% (or more) and try to keep charging?
Do you not charge it every night? (I have always charged all LiIon batts every night [mostly] and I have yet to run into issues with ANY batt.)
best to charge the battery with the cover off takes heat away from it
the odd part is that the battery never is warm while charging stays at normal operating temp for a happy battery. Now what I'm thinking is the battery is actually getting warm from something in the phone itself an transfering the heat towards the battery. An this phone has gotten warm like this even when it was less then a month old on box stock none rooted firmware of all types x.x
Hi All. I've been a lurker for a while but have never posted. I can't post in the beans thread until I hit my 10 post count. So here's the deal:
Verizon GS3
Unlocked bootloader
Rooted
Beans Custom ROM 10
Imo's .6 Kernel
I've run Beans version 8,9, and 10, and haven't really noticed these issues until recently. I haven't been able to fix them after trying and searching the forums, even though I've noticed a couple people with similar issues.
1) Slow Charges - I can go to sleep and plug my phone in, wake up 6 hours later and it still won't be fully charged. I could maybe get 50-60% charge. Phone will of course be off and in standby while charging. (have tried resetting battery statistics in CWM)
2) Fast charge doesn't work - I've tried opening the terminal emulator and typing in "ffc." It will tell me fast usb charging is enabled, but I will see no decrease in charge time at all. Someone on the beans thread mentioned going from 59% to 77% in 10 minutes on fast charge. I will make sure it's unplugged, run ffc, then plug it back in.
3) Overclocks won't stay. I'll run something like SetCPU and bump my max clock up to 1900 but as soon as I go to a different app or run a benchmark, I will come back and even though 1900 MHz is highlighted, 1512MHz will be the "max" setting. I've tried Antutu and quadrant. Antutu will tell me my clock is 1500 MHz after the test is run and I look at results.
4) Benchmarks suck. Now I know benchmarks don't necessarily mean anything, But it's a decent way in my opinion to compare how my phone is running to others, when they're running the same phone, rom and kernel. People running beans 10 are in the 5400-5700 range with Quadrant, while i'm in the 4000-4500 range. I ensure RAM is dumped and nothing is running while I do a benchmark test. (others are getting Antutu scores around 7500-7800, i'm getting 6600)
5) Occasional rapid battery drain. This one is a bit hit and miss, It doesn't happen all the time and I haven't been able to pinpoint a cause with it. But I will occasionally get very rapid battery drain, eg, I can just be surfing the web and lose 10% battery life within 10-15 minutes.
If anyone has any information on these, please let me know. I do apologize if fixes are common knowledge, but I have searched and haven't seen any. Although I've used droid for a while, my GS3 is my first dive into custom ROMs and the like.
Thank you for your time.
1. Any time my phone charged very slowy(turned on), all I had to do was reboot it. Now it seems different for you since you're charging it while its off. I've also found unplugging it and then plugging back in has helped when charging.
2. Never have used this so I don't know
3. Again not sure, 1500 mhz is fast enough for me lol
4. I say as long as your phone is running quick, responsive, who cares about benchmarks. They are meaningless.
5. Download either better battery stats(paid) or GSam(free) and see what is using up your battery
I haven't had any issues on Beans 10

I have this same problem and i don't think the Rom is your issue. I have mine rooted and that's all that I've changed.
Yesterday i had my phone plugged in charging for literally 8 hours and barely hit 60%
I got pretty pissed because I've noticed it for awhile. I ended up trying an old cell phone charger i had laying around. I think from the incredible. A different wire and wall plug. Within about an hour i was at 100%
Rapid drain i just have no idea. I use battery saving mode and still the battery lasts like 4 hours with light use. It's so frustrating. It looks like "android system" uses it all but i really don't know why. I've been tempted to wipe the phone and see it didn't seem to happen til i rooted.

Yeah guys those definitely aren't normal results. I would full wipe and try again.
I have actually exclaimed at the speed in which the battery charges on mine. And get around 12-14 hrs with moderate use. But I'm on synergy.
I will say there seem to be some bunk batteries getting shipped with the S3. I work as tech support for Asurion, and that's an issue I have seen more than once. And these are people that have no idea what rooting.. Or even android is. So any rom or kernel combination can be ruled out.
