Mine has been great. Two nights ago I did a test, checked the batt level 93% set airplane mode put it on standby & went to bed. Got up & waited a full 12 hrs, turned on deactivated ap mode & checked 93%. By the way I also have Juice Defender set on standard mode. I have no complaints. I noticed even before I started using ap mode very little drain. What gives ? I've read all the threads on problems people are having & not experienced them. This is my 3rd a500 after having problems with the first two, one was my fault after accidentally knocking off my desk, landed on the charging pin which broke after trying to straighten . Second Amazon sent me a return which wouldn't charge. I've had the new one for about a week & it works flawlessly knock on wood.
