I just got my SGS2 replaced (RMA) and the brand new piece arrive with a completely dead battery. I had to charge to for like 15 mins before I could turn the phone on. I am concerned as my first S2 arrived with a semi charged battery which is usually how L-ion batteries are usually shipped with most electronic devices. Is there a way to check if the battery has been used previously? Any app that will help check the cycles to determine if it is a new piece? UPDATE: I have plugging in the AC Charger and I see a large battery icon with a circle in the middle that blinks every few seconds. This has been happening for the last 15 mins. Any help would be much appreciated.
