I picked up my new Droid Razr Maxx on Sunday afternoon and I made the mistake of using it right away prior to hooking it up to the charger. I probably ran it down to about 10-15% that night and charged it fully when I got home, without shutting it off however. Monday night I ran it down to about 20% and charged it fully again, also without shutting it off. I didn't do a complete charge with the phone shut off until last night (after I finally read these forums). My question/concern is, have I potentially ruined the long lasting battery potential based on what I did the first 2 days of owning the phone? Any feedback is greatly appreciated.
