As far as i can tell i have not had an shutdowns or lockups etc.. while using the LG charger that came with the G2x. I had been using the one that came with my Nexus One and it seems that almost every time i have used it, i would get a shut down or a reboot or black screen of death etc... usually at a full charge. ie i would wake up in the morning to a unresponsive phone.
Has anyone bought an extra wall charger or a Car charger that did not cause any issues? If so where? Did anyone buy the ones ("They call it a Universal charger" ) directly from TMobile? Since technically in the manual LG says to use their own charger..but i thought all manufacturers say that.
I am wondering if the one that came with the Nexus One has the built in circuitry for not letting it get to much voltage or whatever they are supposed to block. I have seen some online that say they have something built into the charger...which not having it may be the issue.
I thought the phone does ..switches to trickle charge when almost full. At least my Nexus did... but i get lock ups sometimes no where near full... with the G2x. And i get it every so often with my Car charger too.
Thanks
I've been using the ones from my HD2 no problem yet.. :knocks on wood:

Before you go out and buy a generic charger from Ebay, make sure you check out the miliamps on the chargers. The G2X AC charger is 1000 mA which is pretty high. My previous Samsung phone was 700mA which was less. If you buy anything that has a low mA rating it will take longer to charge. I bought a cheap generic charger from Ebay before and it was rated at 300mA!!! That's barely enough to keep the battery level the same while you use your phone or have it on. Don't use your USB plug from your computer because the mA is very low and you will run down your battery having your phone on. A good 2nd home charger is the Blackberry AC charger. They are under $5 from Amazon and they are 700mA.

For the car buy this Motorolla charger. 950mA! and about $6

Thanks for the input everyone. I will look into grenademastas suggestions.
Just an FYI... still
...as far as I know, i have not had a "self reboot" (well no lockups for sure... self reboot you have to look for i guess...) since i began using the charger that came with the G2x as my primary charger, for overnight charging.
I also started rebooting my phone once a day when i take it off the LG charger.
And also since i did this, I have not woke up to a "unresponsive" phone where i had to do a battery pull. I was using my Nexus Ones charger as the primary charger.
And i had switched from Launcher Pro to Zeam. So i will try going back to Launcher pro for a few days and see what happens. As i thought original it was Launcher pro causing reboots and lockups. Zeam is pretty fas so if no lock ups , i am not sure what i will stick with.
Thanks for the link, I ordered one for each car. Ive seen a few Micro USB chargers locally for $10-$15 but they never list the ma on the package.
My current charger can only keep up with the N1 when not running GPS. it barely keeps the G2X steady

Trust story. I found a micro usb charger in my closet and started using it the same day I got my phone because the cored was longer. It was taking FOREVER to charge and when it was at 100% if i started using it while plugged in it would still drain to like 97%. I was like wtf everyone said this phone charges faster than others. Then I checked the specs of the charger and realized it was the charger for one of my old bluetooth headsets and the output was only 150mah .

When using in car, playing music from Pandora, and using google navigation phone uses more power than what charger can provide. Ive got it on a fast charger, so its supplying more current than a standard one,....its not overheating because when it does the charge light blinks green then red. Screen is on all the time during navigation and set at 30%. Anyone have same experience? My Droid X would keep charging in same situation. This is going down in charge %. I was using das bamf rom, just switched to Perfect Storm 1.2, maybe will make a difference?
Also when plugged in to power its underclocked to 768mhz.
Would switching kernals make a difference?
What is the amp output of your car charger? I'm pretty sure you need at least 1amp to feed this device while using GPS and data. maybe 750ma will do it, but most recent phones, tablets, mifi devices, etc. require at least 1a.
Same thing is happening to me, I dont think the charger puts out enough juice. I've ordered a verizon 2amp dual USB adapter, hopefully it will put out enough to charge the device.

But I am using GPS with screen on the whole time, curious if you are too?
Turn your screen off. Navigation and Pandora will keep playing and your battery will slowly charge.

I guess your right,...it must be more of a power hog than my X was using the same charger.
I've used Last.fm streaming with GPS navigation and screen on for multiple hours at a time without any battery drain. I don't know what car charger I'm using (an unofficial one that I bought for my Moto Droid), but I've been running the Das Bamf kernels for the most part. Even before I installed any of those kernels I never noticed any battery drain while plugged.
Same problem here.
I have a Belkin micro-charge 1A. Can't use navigation and Pandora without losing charge. I had the same problem with the iPhone before I bought the 1A charger, the 500mah wasn't powerful enough.
And turning off the screen when you're in navigation mode defies the purpose.
Do you turn off the screen of your Garmin or Tomtom while navigating? I didn't think so...
Let us know if a 2A charger does help.
Thanks for the feedback.
I called Rocketfish to try and find out just how much powa the charger I posted earlier put out. They didnt know, lol. They said usually its posted in their system, but that one wasnt.
But, after thinking about it, I had the screen on 100% brightness because of glare I was getting. Will tone it down and went to utkanos kernal and see how that rides out.
You need to get a charger with more power. I got one made for an ipad. It has 2 USB ports. Made by scouche or something like that. Had this issue with multiple chargers even on my droids.
this is completely normal for other phones too, like the nexus one. using NAvigation with the car dock pulls more power than the charger can supply, so the phone slowly drops while charging. not much can be done about it. i bought a 1.3 amp car charger. helps a bit.
So I was wondering if I could find the original G2 wall charger, the one that came in the box. I bought my phone from craigslist and that guy didnt have the charger for some reason. I've been using some motorola one and very happy with it cause it didnt have rapid charging and battery life was great too (not sure if the charger plays a role). But couple weeks ago the wire got loose and wouldnt connect properly, so I bought this: http://cgi.ebay.com/ws/eBayISAPI.dl...331986&ssPageName=STRK:MEWNX:IT#ht_1184wt_950
Ever since I've been using that my phone goes to 100% from 10% in two hours, and battery life has been bad too since using that. I have used the phone the same was as before, I even calibrated it again, tried it with setcpu and no setcpu, used edge only also, tried different roms, used just wifi only etc, and battery life still not same as before. I mean it has to be the charger right? Otherwise it wouldnt have made a difference in using a different one. So I'm trying to find opinions from you guys to see if I can find the original one ( I have no idea what it looks like) or a similar one from ebay/amazon. Thanks for reading!
What is the rated Output on the charger that you have? The stock one is supposed to put out 1 Amp (1000 ma). It isn't uncommon for it to go from 10 to 'full' in 2 hours, but just because the phone shows it full, doesn't mean its there. Are you charging overnight or just for that 2 hour period?
Yes I am charging overnight. Output says 5V, 1A, so I'm guessing thats 1000ma/1Amp?
The G2's cord is rounder at the USB end and the Plug- in end, but I would think it would not make a giant difference since I use a Motorola one since I don't know where my original one went.
OEM HTC charger
I'm not sure if your still looking, but i bought a Brand New OEM HTC charger from eBay. It was the same thing that came with G2. I'm pretty sure by the time you see this it will be sold but they list them everyday so just look at the sellers other items.
Since I'm a new user i cant post links, but the item number is 160619103766

That is the maximum current supported by the charger, but the device may request a lower current. Use something like Battery Monitor Widget or Current Widget to see how much current is actually being drawn over the USB port. The most accurate reading will be taken when the screen is off, the CPU is idle and underclocked, all radios are off, etc.
I had a cheap no-name AC adapter for my DZ, but it caused the touchscreen to go bonkers. I ended up buying one of these adapters:
http://canadacomputers.com/product_info.php?item_id=039726
Inexpensive, and having two USB ports is very convenient. One goes to my Mugen DZ charging cradle (phone + spare battery), the other to my BT headset. Any standard USB cable will work. It does not cause problems with the touchscreen, so I can continue to use the phone even while it is charging.
The best I've seen on a DZ is about 650 mA net charge, which means an empty 1800 mAh battery should be fully charged in about 3 hours.
I've seen logs of my dz charging at 680-780mA, so long as you have a 1A output charger it should charge the same. The output is the max rated output, not what its feeding to the phone to charge.
On that note most moto chargers I've seen are 700mA max out and same with a lot of samsung chargers I've owned. I use my original that came with my g2 as well as an old htc diamond wall charger with a sony usb cable lol, I get the same charge from both.

Hi guys, I got 2 subject so I thought I'll just make one thread for this.
I'm from EU so I used my US charger with an other plug. Seemed to
work great, doesn't complain like it does with my HTC phone charger.
But now the charger gets pretty hot, along with the USBplug that is in the charger. Should I be worried? I would say its about 50-70celsius.

Sure? Does your get hot?
The charger should handle ~220v as we got here. So I don't get why this shouldn't work.
Isnt there a way to find a compatible European charger without paying 30$ for the travel pack?
Pretty much any micro-USB charge will charge the Touchpad, it is just some will be quicker than others. I am charging from the USB port on my laptop at the moment and it has upped the charge by 8% in the last hour or so with the screen off.

Yeah but the normal one gives about 30% on that time. But as I said, it should work, no problem. I don't think its uncommon for it to get hot but I'm not sure tho
My official charger gets quite warm, together with the USB plug. Clearly that is the only device that will charge at full speed and without a warning on the screen. However, as I was trying to point out, you don't have to go down the official charger route if you are prepared to either accept the on-screen warning or a slower charge rate. The Blackberry Playbook charger gives 5V 2A and although it comes up with the on-screen warning charges almost as quickly as the official unit.
I bought one of these http://www.mymemory.co.uk/iPod---iP...s-USB-Charger-and-Socket-for-iPod_iPhone_iPad the other day, rated at 2.1 amps (though the unit shows 3 amps). I get the dire message about not enough voltage or current but it works fine and quickly. Obviously I don't use the supplied Apple cable...
This weekend I went on a trip and decided to try out using my Skyrocket as a GPS navigator using Google Navigation. I had my phone mounted and plugged in the whole time for about a 2 hour trip. The screen was on the whole time usually at high brightness (it would dim every once in a while.) When I removed my phone from the mount I noticed the power was down to the low 60's, which struck me as slightly odd since it was plugged into the charger the whole time. The next day I tried to use it as a GPS system again, but even as it was plugged in, this time I literally saw the battery gauge draining. When I turned off navigation and the screen the phone would finally start charging.
Is this a common thing or is there an issue with my phone or possibly my charger? Does doing all those things really drain the battery faster than it can charge it? One last note is that I was not in an LTE area during this, or at least not the whole time (I only noticed it was LTE at one time during the trip.) When I saw my battery draining in front of me I definitely was not in an LTE area.
Might be your charger. I'm having no problems using it as my primary driving, hiking and general outdoor GPS unit. When on car charger, it's charging faster then it drains.
I believe my charger is an old Motorola car charger that came with my wife's old dumbphone. It's actually not even a Micro-USB charger, but rather a Mini-USB with an adapter.
This may be a dumb question, but the actual charging port shouldn't be the issue right? I'm assuming those are always the same standard.
Check the car charger amperage output. I have an old car charger to USB that only puts out 750mA and another thats puts out 1A. Anything less than 1A with the navigation running (which means the screen and GPS stay on, of course), and it'll still drain the battery (and even at 1A it may still drain).
I've been putting off getting a powerful enough car charger myself. You'll need one that puts out 1-2A I would think. Most of the common ones off the shelf are 1A or less, and I've heard that some chargers reported max output is not as good as reported.

i second this...my phone won't even charge on some wall chargers, unless 700mAh or higher. let alone do any battery heavy functions like GPS. get something with at least 1a output
I'll try swapping the chargers. I have an overpriced AT&T one that I got for free that is collecting dust.
If the charger has 1A output then it should be OK
I'm having the same problem with my Skyrocket and cheapy charger that I bought at Fry's. Use the navigation with screen on and my battery is less than when I plugged it in.

When I was looking for a more powerful option, I saw that one on Amazon as well. My only hesitation at buying it was why it was so much cheaper than all comparable options at local stores, or even online...I've heard that the cheapie chargers may not actually output what they say...though for $4 plus shipping, I guess it's not much of a gamble. Let us know how it performs!
P.S.-Pulled up the reviews...not too many positive ones (though 1 or 2 were good): http://www.amazon.com/GTMax-2-Port-...iewpoints=1&sortBy=bySubmissionDateDescending
Its actually more than just the charger output that is a problem. If the center two pins on the USB connection aren't shorted, the phone will treat it as a USB connection to a computer, not an AC connection from the wall, and only draw a max 500mah. I had bought a 1amp and 2 amp charger for my car and would get the same results as the 500. I started to think it was my car limiting my output!
But I then found an article detailing this problem that I've since lost the link to, but the method worked. Pop open the charger and solder the 2 middle connectors together and all is good.
I don't know why the charger manufacturers don't know this... Or maybe this phone is doing something new? Maybe someone makes a USB-> micro USB with the center pair shorted in cable?

Just Google "Solder USB Car Charger" and you'll find plenty of tutorials about how to do that. Personally I'd rather just buy one that out of the box works.
Tried out my AT&T charger (which can be found here) and it worked perfectly. Set up the GPS and everything and now it will charge even while doing all that stuff. Thanks for the help
I have the same issue with my SkyRocket. LTE makes no difference. If I'm using Google Navigation or Waze and the Screen is on my charger/phone can't keep up with the battery drain. If I turn the screen off and keep the GPS app running the battery either doesn't drain or doesn't drain as fast.
I've checked my car charger and it's one of those dual usb ones, with a 1 amp port and a 2.1 amp port. It has no indication of which port is which, so I don't know what port I'm using at any particular time. I've tried both and the effects are the same.
Regardless, when the phone is plugged in to that charger the phone reports that it's an AC charger. Supposedly that means I'm getting at least 1 amp, right? So why is 1 amp not enough?
I don't like the car charger you guys suggested because it has the curly cord. I'd rather use a car charger that doesn't come with a cable so I can plug in my own usb cable.
Any suggestions?

Will it be ok to buy it or will it harm the phone and I should just stick to 1A charger?
It will work without any issues. I am using Nokia charger that is 1,5A without any issues.
Just want to make sure there's no chance its gonna fry my phone phone somehow, 2A is still 25% higher then 1.5A .
I bought a 2.1A dual charger from Fry's last night.
Freakin thing is even worse at charging than my .7A single charger is.
I'm not buying anymore chargers unless they have written reviews from people stating they work properly.

If you run into a good charger pm me. If I'll buy this charger and it works out to be good I'll let you know.
Having a power supply greater than what u need is actually a good thing, it'll provide a more stable. current, assuming its of decent quality. Your phone will only draw as much power as it needs, in this case 1A.
I will say that cheap DC power adapters appear to wildly vary in actual current delivered. I am a little skeptical of a charger sold from Hong Kong.
And, in my experience, you WILL need a full 1A of power when doing something like GPS navigation since my 750mA (well, thats what it says on it) charger can't keep up with that level of power draw.
Anyone who is good with electronics know a good way to test the output of these chargers directly?

So I just got my charger today, had 1 drive with it so far with gps on and the phone actually got charged without exploding ^^
This is the charger for the lazy people http://www.ebay.com/itm/400281723676?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
It come without a cable and from first impression it looks pretty good.
Thanks, I just bought one. Hope it doesn't take ~30 days to get to me like it did you.
A little update:
Yesterday I had 2 drives with the phone the charger connected and the gps on, first was 50 minutes second was 35, both times everything worked great and the phone got charged.
Today as I was driving back home after the phone on with the gps and the charger for 10 minutes I received a "battery temperature too hot, stopping charging".
I can relate a few factors to this, first when i entered the car it was scolding hot, second probably the car mount was also hot and 3rd my case is really cheap and chocking.
I downloaded a battery temperature widget and I'll check the battery and the charger in a few different situations, with and without the case when the car is hot.
Edit: I checked the current the phone takes while being connected to the wall and the cat charger and they are both approx 860mA so the issue comes to the phone itself.
Overheating
When I had my Nexus One I had overheating problems.
It happened when doing all of the following together:
- connected to car charger
- gps
- navigation
- screen on full brightness
- on dashboard on very hot day
The phone was never the same after the first time it overheated (unstable). Eventually got HTC to replace the motherboard to resolve the issues.
My point being that when you do all this stuff at the same time you have a lot of current flowing through a pretty tight space with very little cooling.
I am paranoid about my i727r getting fried this way as well ... so I am constantly checking to see if it is getting too hot when I am navigating.
I'm guessing at our hot summer I'll have to cut back on the charger or the gps.
Still now before it's really hot its a good time to experiment with everything icluding pointing the air conditioner on the phone ^^
