[Q] Battery cold/not charging & phone won't boot - T-Mobile LG G2x

Went to sleep last night with phone running perfectly fine, battery around 35% when I put on charger, woke up this morning phone was off and would not boot up even though it was on the charger. I took the battery out and it is quite cold for some reason, it is 85 degrees in this house but the battery feels like its been sitting in the refrigerator. I have been trying for about an hour now to get the battery to charge or the phone to turn on with no luck any ideas anyone -_-

Plug into computer does it get recognized, plug in without battery and try to get it in to software mode...

It gets recognized only if it plug it in without the battery. I don't really know how to boot it into S/W Upgrade without the battery inside unless I'm flashing a recovery, which I still seem to be able to do.

Bad battery then, try holding the battery in place firmly against the prongs just in case.

Red and Green blinking light. WTF does it mean?

Happens randomly when charging. What does it mean?
Charging fault. Happened to me when my battery was way too hot.
Your phone is overheating.

Could also be faulty voltages coming from the charger.

So best course of action is simply un plug? I get this too during heavy gps usage or heavy streaming via flash.

Yea unplug and let it sit for a while. If you are in your car, best thing that I found you can do is hold the back of the phone up to an AC vent for a couple minutes. If you are home or somewhere with a charging port this I found worked.
ONLY TRY THIS IF YOUR BATTERY DOESN'T FEEL LIKE ITS OVERHEATING.
This happened to me about 2 weeks ago, phone said overheat but the battery and the whole phone was cool to the touch. What I did was turned the phone off, popped the battery out, plugged my phone in to the wall outlet, then popped the battery back in. Started to have the solid amber light that it was charging. After 20-30 minutes of that, booted the phone up and it charged like normal and said that temp was back to normal again. If you follow this and boot the phone up right after you pop the battery in, you will still get the charging error.

Bump Charging has helped!

ok, so I'm running faux's rom and I have run CM 7. I have tested this a few times and each rom and it seems to help improve battery life.
Since the drivers are screwy I noticed when I charged my phone it would say 100% but I would unplug it and it would drop down to 97% right away. I think the lower number is the accurate one, So the battery really isnt getting fully charged because the phone thinks it is so of course it will die sooner
So what I did was let it charge to 100% then unplugged it, it went down right away. I plugged it back in and it started charging again, in a few minutes it showed 100%, I unplugged and it showed 97%, so I kept repeating this then eventually I unplugged and it was 98%, then eventually 99%. After doing this my battery lasted a lot longer. I usually have keep an extra battery on me and usually have to switch but for the first time my g2x lasted the whole day! So give this a shot.. it could help if you suffer from really bad battery life.
Off topic.
Im From Southern California...be visiting New York on Monday. Good stuff...small world some times.
could unplug, then turn off, plug in and charge while off for a while, the unplug and turn on, then plug back in and let charge. then wipe batt stats and unplug. works for me.
I have one extra battery. I never charged my phone through the charger it came with. I always charge my battery with the portable charger. No doubt the portable charger takes 6-8 hours to fully charge my battery, but on the upside my battery lasts for more than a day.

I noticed a similar thing recently. I generally charge my phone overnight while I'm sleeping and use it for an alarm clock. One morning I decided to reboot my phone (my experience is that it needs a reboot every couple of days or various things stop working) before I got up, so I powered it down, still plugged into the charger. I then tried to power it on, but instead of the boot screen I got the device-off charging animation, indicating that it wasn't fully charged, even though it had said 100% before I powered it off. After letting it sit and charge while off for another hour or so, I booted it, and I think I got exceptionally long battery life that day (although my days are all so different it's hard to compare one to another).
I think bump charging does help, but its not good for your battery in the long run

well hopefully they fix the driver issues so we wont have to do it too much longer One can hope right? hahaha

Weird battery glitch.

So, got this weird glitch. I'll have say 30% of my battery left and I'll power cycle and suddenly I'll have something like 4% left. And power cycling doesn't help or anything. And plugging it in just charges it from that 4%. Anybody got anything?

Just thought about this. I should probably let you know I'm on the latest official stock.

Im runnings the official Roger's GB ROM on my Infuse ATM and I've had similar issues. Mine goes a bit deeper though.
When I first got the phone, it wouldn't charge to 100%, whether it be on or off. When the phone finally charged to 100%, the second you unplug it, the battery widget I had and the built in battery meter on the phone said it was at 80%.
While using the battery, it would drain, sometimes suddenly dropping from 40% to 10%. The only way to get the phone to charge to 100% while its off is to charge it for about 8 hours or overnight. Even then, upon bootup, the phone read anywhere between 80%-85%
This is the OEM battery. Im going to try my luck with a battery off eBay that claims to be "OEM", but so far charging for 7 hours straight with the phone off, it wasn't able to reach 100%.
So im hoping it's not the phone itself. Ive charged the phone with various charges, usb cords, and used juice plotter to keep track of things. Definitely something fishy going on because my graphs always show a sudden jump from 85% to 100% in a span of less than a minute =\

I don't think it's b/c of the rom your on, happened to me when my phone was stock. I tried to let it die, but once it hit zero percent, it just kept going till the "true" battery percent was drained. Im on S7 now and it still happens occasionally..

Dead battery symbol? Phone wont boot

I have a regular samsung battery and an extended battery for my infuse. Throughout the day i will be using the phone and it will shut down and then flash the ibfuse charging wheel and then show an empty white battery with no charge.
I have found other posts online that say to pull the battery and when you put it back in to immediately plug in a charger and it boots up. This works for me every time however it is very annoying when it does this five to ten times a day. And it happens with either battery. Both batteries do this when fully charged.
I am getting a new phone soon and blowing this one up with a stick of explosives. But any known fix would be appreciated until then.

Have you tried wiping the Batteries' stats? I have no clue if that will help since they do it when fully charged, but who knows... It may help/work.
I have a similar problem, though the phone doesn't seem to shut down much anymore. wiping battery stats did not help. It's slowly gotten better, but far from perfect.
When the phone is on I can charge it and the phone will recognize that it is charging... but if i unplug it and plug it back in it doesn't seem to recognize that it's being charged. It's been the same on several different ROMs.
If I shut down my phone it will absolutely not start without pulling the battery and plugging in the charger.
My contract is up in May or June... As much as I enjoy all the work that's been done for this phone my particular phone seems to be getting a little long in the tooth.

Phone keeps shutting down unless plugged in

Hi guys. I have a weird problem with my htc one x that started recently. I got it about a year ago but from like last week, it keeps on shutting down (not restarting) and then I have to wait a bit before I turn it back on. This is because if I turn it back on straightaway it starts to overheat and then turns off. When I manage to turn it back on it shuts down after a bit of usage. The only way it works properly is when it's connected to a charger which basically means its unusable. I'm thinking that maybe I just need to change the battery but since it will take some time and effort, I wanna get some opinions and be sure. Thanks in advance. The phone is on official stock and I've tried factory reset.
The fact that it doesnt overheat and shut down when plugged in leads me to believe its not the battery since the battery gets even hotter when plugged in. Also, since you are able to turn it back on, that means theres still a charge.

It does get extremely hot when it's plugged in and sometimes turns off but that's only when I'm using it for web browsing or something. If I'm not using it when it's plugged in that much then it's ok. And whenever I turn it on it keeps giving different battery readings. Sometimes it will say 80%. Then if I restart it it will say 30%. And sometimes it will have an exclamation mark where it's meant to say the battery reading :/
Hmm well you can certainly change the battery then. Have you taken this phone apart before? Be gentle or you could end up breaking the screen and also, you have to take the whole thing apart to change the battery wince the battery connects on the underside of the mainboard
