Will a phone battery explode if you leave it plugged in for too long?

[hoo]

So my PC never came with an option to connect to the internet wirelessly. Since I'm a handy boi, I used an old phone and the PDAnet app to connect to the internet. Basically this makes my phone act as a WiFi router that is plugged directly into my PC to give it internet access, if that makes sense. Well I've left my phone plugged into the computer since about August-ish, (so for about 5 months) and just now I realized that the battery on the phone is bulging pretty bad. Will it eventually explode or something?

Sorry if I sound like an idiot. :v

If the phone battery is bulging it is unsafe to continue to use.  Do not continue to charge it, and dispose of the battery at a location that can recycle rechargables posthaste.  The best case scenario is that the battery just stops holding a charge all together, whereas the worst case scenario is catastrophic failure and fire.

Don't take the chance.

I agree with OneUnder, dispose of that battery in a safe manner ASAP.  You can buy a USB Wifi adapter , they're relatively cheap now.

Being plugged into the wall for an extended amount of time shouldn't be an issue by itself, but weeks or months of high currents ( from constant screen on, constant wifi hotspot, etc ) being pulled from the battery or going through the device can be bad for it. I see older phone displays at Walmarts all the time where the phones are dead and the batteries have begun to bulge.

Speaking of, as others have said, you should promptly dispose of a battery that's begun to bulge or deform.
