Sometimes when plugging my phone into a charger it will not charge at all despite the charging symbol appear. This is usually solved just by unplugging and plugging the phone back in.
However, just now I had it plugged in while watching YouTube videos when it become hot to the touch. So I unplugged it and continued watching videos. After 10 minutes it was still hot, so I downloaded a battery temperature app that said it was at 49C. Figured I would just turn off my phone and since it's cooled off.
Should I contact HTC about this? Was it just heavy processor load that could have caused it?

I'm still relatively new to the whole android platform. Evo being my first. Why does the evo not sleep when charging? I have the issue of rapid battery drain when I unplug the phone from 100-90 in a matter of minutes. This bugs me to no end. The only way I am able to get around that is to watch for the phone to ding 100 and immediately unplug it and turn it off.
I believe that, and (correct me if im wrong), if your phone is awake, it is being used to its full capacity all of the time. CPU is running and doing whatever it does that drains the battery like it does when its unplugged and being used by the user.
Since the phone doesn't trickle charge it stops charging at 100% until it gets down to ~90% (all the while still reporting that it is at 100%). It stands to reason that if the phone doesnt sleep while its on the charger, its using this cpu power and this is the culprit of the rapid battery drain, and to that end, the culprit of a lot of people's battery woes.
food for thought i guess. that's my take on it.
There are numerous discussions about the charging thing. Search, or at least Google. The most intriguing answer I ever saw to this was that the charging system was set up to protect the Li-Ion battery from degradation by not cramming it full of charge all the time. (The OP on that was a bit more technical, but you get the idea.)
If it bugs you that much, you could root your phone, flash a ROM that is undervolted and compatible with SetCPU, install that, and then set a profile up so your phone is underclocked when it's charging / charged.
I searched xda prior to posting specifically about sleeping while plugged in. My query isn't neccisarily about charging bit rather the sleep function and awake state of the phone while its pretending to charge.
I'm curious as to whether this is hardware related or not. For example when the phone reaches 100% and stops charge could the phone then actually begin to sleep. Unless its physically impossible for the phone to sleep while there is a usb chord plugged into it.
A little test I did with this over the past two days. At night I charged to full and took the phone off the charge and went to bed. I woke up and only lost about 4% all night and was able to use the phone on the way to work never going below 90%
The next night I left the phone on charge all night. Wake up take it off the charger and within 10 minutes I'm down to 92%
Keep in mind I'm not blaming charging on this. The first night lasted longer off of the charger than the night on the charger simply because the phone was allowed to sleep through the night.
I could be wrong
you can set the options it will say 'screen stay on while plugged up' or something to the like
or when you plug it in, just push your lock button (the top power key)
also you can get a brightness widget and put it on your home screen. that way you can still have your screen on while charging but it will be dimmed or whatever setting you set it too.
hope this helps!
Your screen being on vs off while charging does not factor into the asleep vs awake time of the phone.
for an example of this, a freshly rebooted phone on the charger, with the screen off for 5 minutes, will have an "up" time of 5 minutes and an "awake" time of 5 minutes.
this is true while the phone is plugged in and the screen is on or off.
simply put, your awake time on the phone is always going up as long as the phone is plugged in, double this with the fact that the phone stops charging at 100% and you have constant drain even when plugged in.
the phone shuts off at 100% to protect the battery. If you want your phone asleep then turn it off at night. that is the only way to put the phone to sleep try searching app market. Other then that the only other way is to push the power/lock button at the top
Mobile internet fail. Sorry double post
Hi guys,
I was playin Temple Run and the battery was about 5% or however close to be fully discharged. Suddenly the display was flickering, or like something this. The phone suddenly powered off.
I tried to charge the phone with the charger in the plug, but after some seconds the animation disappears, then reappears in few seconds and disappears (about when the charger animation goes to the top for the second time).
The GN is connected to the PC, and does not power off: but the charger indication is stuck at 0%
What's happened? I doesn't made something wrong!! I used to discharge my battery often!
I also wiped Battery Stats in recovery, it does not helps.
The ROM and the Kernel are inte signature. I never made overclocks or something like this. Please help me
When I detach the USB cable from GNexus it power off (like when it's normally discharged)
EDIT: Suddenly the % went to 2%.
With lithium-ion batteries like the one in the Gnexus 'like' being charged. They do not have a memory like ni-cad batteries. Severely discharging or overcharging our batteries can physically damage them. If you store the battery for extended times, leave it at 30% charge.
As to why you experienced the freaking out from your phone, when batteries get low on charge, the voltage and amperage output drops. When your phone has a low draw, you won't notice this. Under high draw like gaming, it may not be enough to power your phone. Turn it off and plug it into the factory AC charger. Let sit for at least 30 min or so. Then try to power up.

Temple Run sucks battery like a...you know.

Yeah. In 30minutes of game the battery went down of about 10%. Web browsing in 3G is less battery expensive
Your battery might be damaged if its acting up when it gets low. Try not to run down to zero.
zippity doo da.
Whenever you get a chance, plug that phone in.
In the car on the way home? Plug it in.
Sitting in the office? Bring your charger and plug it in.
If its under 70% that is. A small charge will always be healthier than 0-100.

i just experience the same thing i thought i burned out the phone home recharging it will help its look like it stuck on 0%
EDIT : its start recharge also
the way the screen flicker and the sound its made was just the scary
I've notice since day one that the charger gets excessively hot. So much so you can't hold it longer than a few seconds before you have to let go. Is that normal? Lastly, I noticed it would charger much slower, at times. If I let it cool off. Reboot and start the charge again, it goes back to charging normally.
Question guys... I just got my Moto 360, and I love it. For the past two nights, I';ve gone to bed with the watch being around 50% battery. I put it in the charger, it shows it's charging, and I go to bed. I wake up and the watch is off, and cannot turn on. I take it off of the charger, wait a couple of minutes, put it back on the charger and the white charging light comes on, and it shows completely drained.
Why is my watch draining while in the charger?
Is it paired with the phone?
Maybe some app is draining the battery...
Yes, it is paired with the phone and remains in the charger all night. Even if apps are draining it, it should still be charging as its in the charger, correct?
qi charging is like usb charging. its slooowwwww, so if a rogue app is on board causing mischief, the charge of the wireless charger may not keep up.
Make sure the light on the bottom of the charger is on. Because if it gets too far away it drains.
I had this issue the first night I got my watch. It was quite disconcerting watching as the battery level decreased while it was on the charger!
I solved it by restarting the watch, switching to the default watch face and putting it in theatre mode while charging.
It hasn't had the problem since and I've now got the 500px watch face (it's beautiful!) and the watch charges in around an hour from <10%.

Thanks for the tips all. I"ll try all of this and report back.
HI,
I am having this issue, however I had my watch at 90%.
I then try to charge my watch and basically it does not charge and it seems like it is discharging. I still get the charging screen with the blue circle.
I have try the charging on both the standard dock charger and another Qi charger i have and I get the same issue.
I have factory reset my watch and it doesn't work. I cannot charge my watch now and now I cannot set my watch as I am not at the 80% needed to set it up
I have turned my watch off and I am at around 40%. I have left the watch on the charger when off and I can get like 1 or 2% charge in per hour... Anyone has this issue?
I am on the newer 5.1.1 update.
I'd bet that's down to a bad lead
Update to my problem, the device can only charge when it goes down to around 25%. Anything above that it would refuse to charge.
I have informed Motorola and will be sending it in for repair or replacement.

Good luck with that! My battery is starting to act up like that as well.
I have the same issue. My watch charges, I can see it going up. But, if I leave it on the charger over night, I assume it reaches 100% and by morning has depleted and shut down. The charger as well is shut off (no light on the bottom). I have to unplug and plug it back in to get it to start charging my watch again.
I find this from time to time; I absolutely double check to see whether the light is on at the bottom of the charger every time I put my Moto 360 in the cradle. If it is off, I unplug everything, replug everything back in and make sure I have the LED lit. This seems to be a problem with some of the chargers. Also, I typically put the watch in airplane mode when I put it in the charger overnight. There's not point in it "talking" to the phone while I'm not awake. (I don't know what they'd talk about anyway).
Previously coming from S8 & Note 8, while playing power demanding games plugged in it would hold and charges just fine but now it's barely gaining any. It says "fastcharge" but doesn't feel like it at all... anyone having similar issue?
I been on 4% past 30mins or so while playing Lineage 2 Revolution. Sometimes, I would lose 1~2%!
I have the same issue. I am charging S9 via cable with quick charge 3.0 adapter in my car. Some times it charging fast but sometimes it discharging even in idle. I found that it can be related with phone heatup. In sunny weather phone is warm (battery temperature about 40C-42C) and phone not charging. If I put phone in shade then it start charging in 5 minutes
