just had a thought, my g2x just started rebooting like crazy i.e it would get to the tmobile g2x android start up animation and after it finishes it would reboot. my battery was around 30%-35% at the time i was thinking maybe the battery cant maintain a decent voltage and it falls below the g2x voltage threshold while under load and boom instant reboot. this could also explain why some batteries heat up to hot as well, they dont have a high enough discharge rate to keep up with the demands of the phone.
this can be solved one of two ways get a larger capacity battery of the same discharge rate. or get a higher discharge rate battery of the same size. both of those will allow the phone to draw more power without overtaxing the battery and would keep the battery cooler as well.
I wouldn't be surprised if the battery drivers are the culprit for all our issues. The phone can't properly read the battery charge and so the battery overheats or the phone reboots itself in hopes of getting a better reading on the battery.
i noticed my phone starts to heat up when the battery level hits around 40%. i never really understood why.
Mine once rebooted when it was plugged in and 100% charged. I think when it's plugged in it draws power from charger not the battery. So your theory, if true, only explains some reboots, not all.

I may be mistaken, but if it was in fact 100% then it was probably drawing from the battery at that point. I believe that once they reach 100% they will cycle between battery usage and charging.
well i know from using lipo batterys in my r/c planes and cars that if you draw them below 3v it can damage the battey im not sure what Li-ion low voltage is but its near the same basicly once the battery hit around 3.6 volts at rest its empty and will not hold voltage at all.
and for the 100% full charge if the battery drivers is fubar it could be overcharging your battery and damaging it so it has less capacity so when it pulls a draw it cant keep up and reboots
I plug my phone in every day before going to bed, and unplug it in the morning. If G2x doesn't have overcharging protection my battery would have been damaged long ago.
Also, I used the phone several times when it was charged 100% and still plugged in, never saw battery percentage went to 99% then back to 100%. So I believe when 100% and plugged in, it won't cycle power source through battery and charger.

I will add a little information that may or may not have relevance. I have 4 batteries for my G2X (This is my solution to the short battery life). The LG battery, $25 AceSoft battery, and two $6 generic Chinese batteries. None of them including the dirt cheap ones cause my phone to reboot. Conclusions can be drawn from this information but I'm going to leave that up to someone else. If you want to test the battery hypothesis I suggest you buy some of those cheap batteries off of eBay and see if something changes. Would be a rather inexpensive experiment.
I agree, ever since I started using a 1900mah battery from ebay, the random reboots and freezing issues have disappeared completely, and I have been using the phone for almost a month now. Please try a different battery to get rid of random reboots and overheating issue. Hope it will help someone.

you know what, I bought 3 ebay batteries so I can swap them around if i don't have a charger. none of them did the black lock screen. weird.
I had random reboot issues using some of the custom roms + original battery.
Then I bought a charger + batteries off ebay, and reset to original rom, and havn't had a single reboot/freeze since.
i just had my second reboot in cyanogen with my battery at 32% after if rebooted it went back up to 45%. i was playing galaxy on fire 2 when it rebooted. and according to battery monitor it was pulling 931mA when it rebooted.
i think the battery discharge rate is substandard for this phone this is a high performance phone and you cant just stick a normal cell phone battery in and expect it to work. this is in part why some of the reboots are happening and why when people got new battery they problem went away for them.
You might be on to something. Everytime my phone restarts it is because it is overheating.

i wish we had more info on the batterys lg used like the discharge rate and everything. i bet they are .5c or 1c discharge that would be why they overcheat when under heavy use or charging
I got a replacement battery from T-Mobile this past Tuesday, and had two random reboots within an hour. However, since then, I haven't had one issue. 4 days and counting going strong... Knocking on wood. Phone is stock and rooted.
well i know cm fixed the battery should be in his next build also data speeds with gingerbread, should be build 54 not 53, something is wrong with 53 and root access so they are going to have it fixed im pretty sure in 54, here peep this via twitter.........
@CM_arcee RC
My dark magical powers have beaten the G2x's radio into submission. Starting tonight, p999 gets a battery meter and twice the data speed
3 hours ago via web
while that is awsome news i dont think the battery meter for the phone is really the problem it happens when the draw on the battery pulls it below 3v under load the batterys low voltage cutoff kicks in and shuts the phone off and then the spings back up and the phone restarts
I think it could be the chargers causing issues. My gf pulled my g2x charger out of the box and said it made her phone whacky and died after a few hours.
Her comment made me think about it.
I never had battery issues but I use my old nexus one and zune charger.

I have now had this problem twice this week. I have read other posts that sound similar but the issue seems different.
Twice I have shut down my phone at night. With FULL battery. The next morning, I could not turn the phone on. It would vibrate when I hit power button but not come on at all.
Both times I plugged it in and saw that the battery was COMPLETELY drained. I have seen threads where people post about some battery drain overnight, but this was an entire drain, with the phone off.
This is a major issue obviously as both times the next morning I was on the go and had zero battery life.
Any ideas of what this can be? Does it sound like a physical battery issue? Is the phone maybe not actually shutting down and getting caught in some battery draining process?
Help please.
The best way to test the shutdown issue is pulling the battery after it seems to shut down. Try pulling it for a few seconds and replacing it, but leaving the device off. If that produces the same result, try leaving the battery out overnight.
This seems to only be happening if I leave the battery in the phone.
It happened again last night. Complete drain.
Im not sure but I feel like there may have been a buzz as it turned itself off (not sure if its always there need to experiment further). I picked it up and hit buttons to make sure it wasnt just in standby. It wasnt. it was OFF.
Next morning, no battery.
Any ideas? Id love some help as this is becoming a pretty big problem for me.
Have you ruled out a hardware issue already? If not then call the carrier.

This actually happened to me a night before last as well - twas the first night running Smooth Ice 5.1. Are you on that by chance? Not knowledgeable enough to really comment on whether or not that could be it, but it'd be something to eliminate.
I switched to the new leak last night and the battery life has been excellent off charger all day, for what it's worth.
I am on stock everything.
I am still trying to diagnose the problem.
It seems that when I Power Off, occasionally at the end of the power done I will get a Vibrate. When that happens, I think it is draining while switched off.
When the Power Down happens and I dont feel the vibrate, so far I have not experienced the drain.
Does that perhaps give anyone ideas about what might be happening? Some kind of locked in Process or App? Any likely culprits? Any diagnostics that can show, if it does drain, what drained it?
In the past when it drained I plugged it in to charge and checked battery stats, but it showed Display as the largest consumer. Does the About Battery stats reset each time you plug in and start charging?

It always vibrates when you power off, at least mine does.
The battery stats reset after a full charge has been achieved.
I have no idea what would be discharging it while off besides a bad battery.
Put the BetterBatteryStats application on there. The stock Battery Use GUI interface that is built into the firmware will not show you details enough, it will just show what application used the cpu for X amount and caused the battery to go down X amount.
Put BetterBatteryStats on there to find out what is causing the phone to get drained so quickly. Seems like its not going in deep sleep mode and there is some partial wakelock that is keeping the phone from going into deep sleep. That app will tell you what service or application is holding the largest wakelocks and amount of time it does it for. This helps to determine the issue. Without this, you are just speculating on the problem with the built in Battery Use stats/graph in the Status screen.

Something else I noticed...
Over the last few data, sometimes when I power down the phone, it goes through the powering down process usual, but as soon as its done, the phone vibrates and powers right back on...
Anyone experience this or an idea why that would happen?
Just a thought; If I'm charging my phone with a generic charger (500 mA) and shut it off, it will reboot.
If I'm charging with either the factory wall charger or a 12 volt that triggers AC charge it won't.

The reboot happens when I shut down and am not plugged in to a charger at all....
My galaxy S has been doing this too lately (loses all charge when off overnight). It always buzzes on shutdown.
One thing that mine has is a problem with the usb port, it slowly stopped working and now I can't charge it anymore through the port. I'm wondering if there is a physical short there that is causing the battery to drain. Possibly you have something similar going on, or a short elsewhere in the system.
I've noticed that you cannot shut the phone down when charging from certain chargers too, especially in the car. Very annoying.

Hey guys,
Im still having this issue and wanted to hear if there is a known fix or solution?
Honestly, the severity of battery drain you're describing sounds lije more of a hardware issue than anything else. I would contact yoir carrier as mentioned above. Beyond that, trying out a custom ics like sky or embryo might be your best bet if you prefer the tw interface. Im on embryo 5.1 right now and am experiencing better battery health and longevity than ever before with the skyrocket. But the issue does sound like a bad battery.

This happened to me on one of my i777s.
The phone would even not boot up. It will just vibrate. Turns out the battery was bad. Changed the battery. It was still the same.
Then tried another charger, same thing happened.
So then I changed the whole charging port part in the phone.
Voila! Phone worked like a charm.
So if you have warranty change the phone. If not change the charging port. At least in my case.
I came to a conclusion that even the battery went bad because of the bad charging. Might be a coincidence too.

I have 3 S2 phones that I bought as defect and played around with. Two I could fix but I could not resolve the battery issue on the third phone like by buying a brandnew USB charger part (and trying the ones from the other 2 phones. It has nothing to do with the ROM or anything software either. I narrowed it down to be an issue on the actual mainboard. The weird thing is that the battery discharges way faster when the phone is turned off than when it's in use.
Last night I charged my new nexus 5 with the charger my wife always uses with her galaxy s3. I noticed the charging icon turned on (lightning symbol) before putting the phone under the pillow.
I woke up this morning realizing the phone is extremely hot and it seemed like it hadn't been charged at all.
I charged the nexus 5 again with its original charger and everything wad just fine.
Anyone has this problem before? Will the extreme heat damage the phone or the battery at all?
Thank you
Please don't put your phone under your pillow.

Absolutly... and do not use other wall chargers I would say. Especially if you haven't tested it with your phone yet.
But... that still sounds strange imo, it obviously should be hot while charging under a pillow, but why would it be discharged and still hot way after the normal end of the charging ? I'm thinking of a black screen of death i'm afraid..
Happened in the past with my optimus 2x until i got a kernel which fixes it.
And so, exactly the same situation was happening sometime before the fix ; put on charge during the night and in the morning, got a very hot powered off phone with an empty battery despite beeing still pluged...
Just my 2 cents

Thats normal dude...if you use your phone while its charging you are using the energy from the charget to use your phone and to charge your phone...Faux kernel has the ability to lower you cpu speed to avoid heat but its pretty normal for the phone and any other device you have to heat while charging!!!

This, everything gets hot while being used
Like a engine it gets hot while being used
Your phone should get warm, but not hot. If it's getting hot, then there's a problem.
If you're not sure whether the phone is warm or hot, then it's simply warm. You'll absolutely know it if it's hot. Also, try letting it cool (as you've done), then put the phone back on the charger at as close to 100% charge as you can. Once you're at 100%, touch the phone, then wait 10 minutes. If, after 10 minutes, it's significantly hotter than before, then something is probably wrong, because your phone didn't go into "trickle" mode, like it should. If that's the case, I'd be more inclined to look at replacing the charger, than the phone.
My phone barely gets warm to the touch solely from charging. In fact, the battery temperature usually drops and holds at about 26C when I plug in.
Are you using the phone heavily while it's charging?

Its very normal case for every smartphones. However,
Try plugging in another charger if one is available and see if the issue persist. If the charger is defective you can process you should discard immediately or process for a warranty return if still under warranty.
Remove the battery door and battery from the device, inspect the battery and battery connections. Ensure there is no damaged to the battery, battery pins or contacts on the device. If you have damage to the battery or charging pins, please discontinue use and submit the phone for repair.
So out of nowhere my phone has stopped fast charging both wired and wirelessly. I'm using the same wall charger and cable and even my car had a fast charging adapter and also does not work anymore. I tried my old LG phone and it still fast charges using the same chargers/cables that used to work with my pixel 7 pro.
What could be wrong?
Try toggling the fast charge setting on/off 3 times. Try a hard reboot.
If intial battery temperature is too low or high at start of charge fast charging will not engage. Best start temperature is 82F.
A battery failure will skew fast charging.
Any recent upgrades or updates?
Possible firmware corruption or a hardware failure. Use DeviceChek to view the temperature sensors to see if their readings are nominal. A false low or high can disable fast charging.

Try cleaning out your charging port. You may have debris in it. It's surprising how much lint and dust gets into the charging port.

It does but the fast charging speed increase is more modest than with cable charging.
Personally I never use this because it's inefficient and generates more heat. The C port can withstand (or should) many thousands of use cycles. They are fairly robust compared to the old micro ports, they seldom fail.

Try toggling adaptive charging. Pixels power settings differ from Samsung's it seems. Fast charging originates from Google Android... different flavors.
Try a different outlet on another electrical circuit. There may be a wiring fault.
Try replacing the Google brick and cable with a new pair. Always good to have a backup. It may seem like overkill but it's also the easiest and most obvious solution.
Shoot no luck. Turned off adaptive battery stuff, shut the phone off, booted it back up, switched adaptive stuff on ...still no fast charging.
Major bummer
May have to speak to Google about a repair

It's not the phone, it's physics. Fast charging generates a fair amount of heat.
In ambient temperatures of 90-95+°F cooling is needed for fast charging; a fan and/or a damp microfiber cloth. Fast charging will disengage if the battery temperature reaches approximately 102F. Charging will disengage completely at about 106F to avoid damaging the phone.
Charging beyond 82% in high ambient temperatures isn't a good plan for battery longevity...
I just checked my battery temp and it's just above room temperature at 23C (73F)

Thanks for lecture from physics. No, its phone.
I am not talking about issue, that it wont fast charge for very long.
Iam talking about how fast charge never even engage, even when phone is low on battery.
And I never keep my phone on sunlight, also never game on my phone. Thermal management on pixel is just crap.
