Phone won't charge 100%

[UFreefer]

Three days in a row now my Droid hasn't been 100% charged when I wake up in the morning. The phone was on the charger for about 7 hrs each time. It's been charging to 70-90% only. Anyone else have this issue or any ideas to what could be causing this?

probably a malfunction on the charging slot, make sure the light is on ALL THE time, if not, exchange your droid at your provider!
