Help HTC Evo 3D Voltage/Heat Issues

[bobby2478]

I have occasionally noticed my phone getting very hot too. Sometimes when I'm talking on the phone I can feel the screen get very hot against my face, even though the screen is not lit.

I've also had times where it was in my pocket and it got really hot, only way to get it to cool down was pull the battery, let it cool off, then put it back in and reboot. I've only used my stock wall charger and a motorola car charger.

I have since done a hard reset (hadn't been done since before I updated to ICS) to try and fix Swype, and I'll pay attention to see if it gets warm again. I've also setup an alert if the temp exceeds 104 degrees F using the battery monitor I've been using for awhile.

I noticed my 3D got warm again last night, so I checked the temp using my battery monitor app and I saw it was around 99-100 degrees F. So it definitely was getting warm, but didn't quite hit the 105 degree F threshold I set for my alarm.

This started when I was using my 3G connection to try and find a webpage, while I also had Bluetooth and GPS on (which they are always on usually). So not when I was talking on it, but using the data connection. It definitely was warm enough to feel it in my pocket.

Is 100 degrees F unusual (possibly indicative of a weakened battery)? Or is that pretty a pretty common temp for new smart phones if you're using a bunch of stuff at once?

That's fairly common. Body temperature is just above 98 and the phone was made to be held.

evo 3d becomes very hot in normal use,when not charging. When battery is fully charged, i turn on my phone without sim, all apps turned off, but the phone getts extremely hot and battery discharges in 40min. Battery is new, 3.7v 2450mah. After that i can't charge battery using wall charger via micro usb port. Then i pullout the battery and charge it with universal charging dock (stand). Can anybody tell me where is the problem? Thanks

I wonder if your new battery was defective.

Did this happen with the old one?

i just bought used phone without battery. Then ordered new from one of china web shop. When battery is fully disharged, the phone doesn't charges. Just red dimmed light blinking. When i charge the battery with universal charger and turn on the phone it gets extremely hot. Maybe there is problem with hardware or software?

You can verify the software by doing a factory data reset.

That will clear off all information, your settings, apps and let you set it up clean, like a brand new phone.

I recommend just setting up the basics to begin, your account information, and use it a day or two. If reception is good and performance seems snappy, then I'd trust the hardware and software.

If the problem persists, I'd replace the battery, sorry.

Blinking red means that the battery has been run down too far and needs some charge before allowing it to turn on.

It's better to not run the battery all the way down - they last longer if you charge them before that.

the same after factory reset. the phone heats up when it's turned off too.

That really does sound like the battery .

That really does sound like the battery .

Definitely.

Safety circuit is in the battery, part of the charging circuit.

Heating while off - battery.

Thanks for help. i'll try to change battery. I'll post reply after replacement

Also keep in mind the 3vo has know to have battery issues when the battery starts swelling, check to see that I had to change mind once because of that. Battery still worked fine but but hot on or off the charger
