Droid gets very hot when plugged into cigarette lighter in car

That does sound very extreme, but I too have noticed the phone running somewhat hotter than normal. I realized this is probably because the phone is actually has the sun glaring on it, I'm not running the AC, and the cigarette lighter port is prolly a tad different volts than outlet and USB.

I dunno, just a thought. I notice the same with heat, but nowhere near the issues you are having.

Perhaps your charger has gone faulty?

 

Hot battery with car charger

My Incredible battery gets hotter then what I think is normal when it's being charged using the car charger. The house or charging through the computer USB port it's temp. feels normal. I am hoping the over heating won't damage the battery, but I suspect it will.

 

I wasn't seeing mine go above 40c that much... if yours is the same this should be normal, especially for charging

 

Cigarette lighter not working?

For the last couple of weeks I have had the same issue Vulcan, sometimes my phone will get VERY hot and stop charging when its plugged into the car charger. I too have the Verizon car adapter. Mine will usually cool down and charge after I've done a battery pull and restart.

I haven't found a "cause" yet, it just seems to be random, sometimes it happens, sometimes it doesn't.

Sorry I cant be more help, but at least you know your not alone.

 

As far as it not charging when your running navigation, I read somewhere else once that this is caused because the navigation app draws more power than is going through your charger. This doesn't explain the other issues though. IMO if you've had your phone for a while, start by replacing the battery. This could explain/solve both the heat issues as well as the short life. Before replacement (I don't think it will help much, but its worth a try) drain your battery completely; then recharge again and see if it clears it up even a little. If if clears up the issue even a little then you know you need to replace your battery. If not, then replace the battery anyway

More than likely its not your charger, there are hard failsafes that if too much throughput goes through, they trip, and the thing will just give out. I have heard horror stories about charges giving way, and melting the battery out of something...but thats very very rare.

Also, if your rooted and running over clocked; I would adjust your CPU settings as far down as managable for you during charging. The phone naturally gets hot during charging, so adding more heat by over clocking your CPU is just adding fuel to the proverbial fire.

 

Another thread with some info on the issue: (It's almost certainly the sun... get a vent mount maybe.)

Is it the battery or the CPU that's getting hot?
