Last night, I plugged in my Droid X to charge...a few hours later I unplugged it and tried to turn it on and nothing. I checked my plugs connections, re-plugged into a new outlet...still nothing. Few minutes of staring at it..pushing off button..taking out battery..repeating all I could think of..nothing. One more time, (about 15 minutes in by now) plugged in the charger and the phone turned on. States it had 100% charge.. Succesfully used the Kindle app for about 2 hours following as well as using it today with no problems... Any idea what this is all about? I used it a *lot* geocaching yesterday and when the battery got low, it did feel very hot...but this is my first smartphone and I don't know what to expect. Also, this takes the same car charger as my former Dare...Is it okay to use the Dare's charger on the X? Haven't tried it yet, but don't want to plunk out $30 on a vehicle charger if I don't have to.
