I've had too many phones came broke on the charging port. They are very sensitive. My last flip phone the whole port came out when I unplugged my phone that morning. I got dressed and when to the Verizon store immediately.

It really sucks nowadays, because for a lot of phones, there's no other method of I/O outside of possibly bluetooth and hopefully wi-fi. Charging and data are handled by the same port, and all of that plugging in and out just wears out the port at some time.
