When I charge my phone it gets very hot. The temperature gets up to 110. I left it charging overnight and this morning the phone was still hot at 110.8 degrees. It never stopped charging. When i unplugged it the battery indicator was full.
Try an app called SystemPanel Lite. and see if your processor us being maxed out.
Sounds like something is running the processor pretty hard and consuming a lot of power, which is causing the heat.

Has anyone noticed that their 3D drains while it is plugged in? I plug in my phone for charging. It charges completely and the LED turns green. Then it begins a slow drain (as if it weren't plugged in). I notice the behavior on system panel. It shows I have it plugged in, but my charge is slowly going down.
What's going on here? Is this normal?
I read somewhere that once it is fully charged, it stops taking juice till it drops down to 90 percent and draws juice again while still plugged in.
I think this is from the intelligent charging that most new phones have. In fact in every android phone i have had...i put it on charger at night, wake up and it shows full charge, but if i unplug and replug it will drop down to 94ish and start charging again. I believe it is a form of governor to prevent over charging and heating.
Looking at my Battery Monitor Widget information, charging overnight, the battery gets to 100%, then is allowed to drop to about 95%, then charges up to 100%, then drops, then charges, repeating the cycle between 95% to 100% until unplugged. It looks like a saw tooth pattern.

noticed this as well
I love Battery Monitor Widget Pro.
I checked my log file from over night and noticed the same pattern. Goes from 100 to 95 percent. Pretty cool.

seems HTC tweaked it since the EVO 4G, it would drop to 90 not 95. I been using that widget, too, to monitor it.
anyone notice when it starts to cycle back to 100 it stays 99% for a while longer than what would seem normal?
I read that the battery in the EVO 3D shouldnt be charging at any more than 4.2v, according to battery indicator my phone is charging at 4.331v right now. Should I be worried?
From car and hvac experience I would say no. Cuz voltage is always jumping around a little bit around specifications. For instance a car battery is supposed to be at 12 volts but jumps between 11-13 volts. So i would say that your have nothing to be worried about. Just watch the temperature when we start overclocking.
What have people's phones been charging at? Also the battery can get up to 41 C
When idle my phone is @ 3.75 V and while charging its @ 3.98 V. That's using battery indicator from the market with battery at 100 degrees Fahrenheit and @ 49% life.

Using Battery Monitor Widget, mine is charging at 4.34v right now. I don't think my Evo 4g charges that high, I thought it was around 4.1v. I will check when I charge that up later.
On the charger while using it, my phone got to 42C, and above 4.3V. Has me worried
I read something on here a couple days ago that said its normal for new cell phone batteries to become hot during the break in period. Didn't say how long that period was but I would guess a month. And why are you using celsius? That's just making this harder.
Update : 25 minutes charging now @ 4.1 V, 103 degrees F and 60%

I wouldn't be too concerned with the temperature getting to 42C. For it being on the charger, and you also using at the same time...that's not too bad. I've had mine up to 45C when charging and using it. With my Evo 4g, it would get up to 47C sometimes while charging and tethering over 4g at the same time. I never had an issue. The phone has safety features implemented so that it will stop charging if it overheats. I'm not sure what the set point is for that, but when it's activated, you'll get an amber and orange flashing led light. That's letting you know it's too hot.
Haven't looked in to this issue at all on my phone, but come to think about it I do have something weird when charging.. Once the phone fully charges up and hits 100 percent it stops charging. I know this is a safety feature kinda thing but it would hit 100 and then the battery indicator would just show normal while it is still plugged in, and also the battery percentage would drop while still plugged in. Is this normal or no?
A few thoughts here:
1: 43 (Even 45) celsius is NOTHING for electronics. Hell, 50C is 122F. That's about how hot a car will get sitting in the sun on a 95-100 degree day for about an hour. Your cars electronic parts don't get cooked, do they? I read somewhere Lithium Ion batteries can handle up to 60C internally (140 F), and that's safety restraints, which means it's been lowballed. Your phone wont melt from the battery.
2: Yeah, it takes a few charge cycles to set your battery in. It'll run hotter than normal till it does. Think of it like a trampoline. Fresh, brand new, it's hard as hell to bounce on it cause it's so tight. However, after a while, it stretches out, and it's much easier. (Dirty minded people can stop laughing now) Same with car engines, subwoofers, etc. They all have a break-in period. The battery takes about a week to settle in, from what I've noticed. Mine ran hot for the first few days, and it's fine now.
3: 4.325 volts is within 3% of the stated 4.2. It's within the margin of error... But it should also be within engineering tolerances. If the guy who designed the phone/battery didn't allow for a 3% margin of error, he should be given an award for "Worst Engineer of the Year"... It should be 100% fine. Like the poster up there said, 12 volt batteries in cars can range from 11-13 (Id go so far as to say 10-14) and still operate the car 100% effectively. Also, you would NEVER get a full charge into a 4.2 volt battery if you put 4.2 volts into it. You've gotta have a higher voltage on the outside to force a charge into the inside (High school stuff I learned, so I may be a bit rusty)
4: To :Winning:, Yes, it's designed to charge like that. It gets to 100%, and sits there not charging. It will then drain down to 90% or so, and charge back up to 100, over and over. The OG Evo did this, (Albeit not as well) but the battery widgets wouldn't display it. That's why the Evo would drop 4 or 5% in the first 5 minutes of use. You would unplug it, and then the phone would query the battery and figure out that it was really at 95%, and display it correctly. It wasn't really draining 5% of the battery instantly.
5: Yes. Red/yellow flashing light = overheat. You can probably make it do this by sitting it in a parking lot on a 110 degree day in Arizona while charging it and leaving it face down on your dashboard for an hour. You won't fry it in your house unless you have a bad charge cable. A bad charging cable is the ONLY potential source of worry I have about overcharging/overheating/etc. 2$ Chinese chargers don't have any fail-safes installed in em usually. You have a 500$ phone, don't skimp on the thing that connects it to 120 volts of instant electronics death. (Or 12 volts, in the case of car chargers. But that's more like a slow, smoldering, smoky death)... It'd be like not using a condom with the one night chick you met at the bar. You don't plug your you-know-what into ANYTHING unless you know it's gonna be safe
Thanks I've mostly been using the HTC charger. I guess I'll stop worrying
Sent from my EVO 3D
Interesting observation.
Wasn't concerned about the voltage, but was watching the heat level.
With live wallpapers: +10C addition.
My charge temp is 33.9C without.
My charge temp was 42.8C with it.
Guess it'd be kinda hard to cram in a cooling fan for the graphics chip!!! hahaha
Since Sunday my Aria has started heating up weirdly. When charging and while using, there is tremendous heating in the area right behind the optical touchpad.
Also the battery is not charging properly and discharging quickly.
I first thought it may be a battery problem, but wanted some genuine views regarding this.
Will changing my battery remove this issue? Has anyone faced anything similar?
There will always be heat around the touchpad whenever you are charging while using it. Happens to me all the time at least. Unless your battery exceeded 45 degrees Celsius, then that's abnormal.
You can track your battery stats for example, heat with apps in Market.
You said it discharges awfully quickly. Mind telling me, how long does it take for it to discharge from 100% to below 10%?
Really quickly.
For example, I charged the phone whole night from a wall charger, while switched off.
In the morning, I turn on the phone, it shows me 19% battery. I rebooted: 8%. Rebooted again: 2%. This all happened in about 5 minutes after taking the phone off the charger.
The phone used the 2% battery for about 15 minutes on standby, with no internet, before dying.
Now it does not even turn on. The battery is definitely gone, since it has bulged a bit. But I want to be sure before buying a new battery, if the new battery will face the same fate or not.
For now, I have given the phone to my brother who will test the battery in his phone. Let's see.
There's definitely a problem with the battery. It is advised you do not charge a faulty battery. It may damage your device or worse, explode depending on what the fault may be.

New battery should fix the problem. There's no reason to suspect that the phone is causing the problem.
So I heard that the reason why when you unplug your phone it immediately goes down to 98 or 97% is because the phones are designed to charge as fast as possible. Is there a way to program the phone to slow charge? (like overnight) so that it will get longer/better battery performance?
I am not sure where you heard that.
The reason that you unplug it and it is at 97% is because once the phone charges the battery to 100%, it slows down on the voltage. It lets the battery drain a bit, to about 95% and then trickle charges up to about 99%. It does this cycle until you take it off of the charger. So, you may unplug it at anywhere from ~ 95%-99%.
Well, wolf is probably correct, but I believe it is the charging circuitry in the phone and battery that regulates the charging rate. The charger voltage output will be the same at all times.
What I would like to know is how the charging system works and what aspects can be modified by the kernel.

You can make it charger faster in the kernel, but not too much.

The actual reason is that it's "bouncing" the charge in the background, and due to the way the OS set up to report, you don't see it happening. Li-ion batteries are happiest when they are either charging or discharging. The fastest way to wear one out is to hold it at a single charge for a period of time. To combat that, the kernel lets it get to full charge, and then switches off charging so the phone is operating off of battery for a bit. After it discharges a bit, it switches charging back on and tops it back off. That way, you have a full, or at least a nearly full charge when you unplug, and the battery is kept in a constant state of charge or discharge so it doesn't wear out as fast. The OS plays a little psychology with the user. Most users are going to expect that the battery should be fully charged when they unplug it, so once it hits 100% the first time, it no longer displays the actual percentage...it just keeps displaying 100%. After it's unplugged, it rapidly (over the course of a few minutes) scales down to the actual number before it's starts showing the real number. That makes people think it's starting at 100%, and it lets the battery longevity be maximized.
There are certain battery monitor apps that let you actually see the bouncing effect. The one build into Android Tuner is one.
Thanks for the info everyone!

That's what I said.....
I know it sounds weird but it's hard for me to ignore the fact that whenever I charge my phone early in the morning, battery temp - 26C usually, around 4 AM it charges like all hells gone lose. From 20 to 100 in somewhat an hour or more.
Note, my phone is a standard non fast charging/dash charging phone which Ampere reports the maximum current the chip let's into the battery is 820 mA.
If I charge the same phone after some usage when the battery is at 37-40 C it takes around 2-3 hours to charge from 20 to 100.
Does any one here had a similar experience?
