I have charged the phone to 100% 19 hours ago. I am at a 60% charge when I set my phone on my desk. All programs I was using prior to setting the phone down were closed out. Within 5 minutes, the red light is blinking indicating I need to charge the phone. I plug the phone in and the charging screen went from 5% to 60% in 10 seconds.
This issue is not new to me as I have another droid that does it as well. I can't say it's a bad batch of phones as mine was made in week 39 and my wife's was in week 42 yet they both do the same thing. This does not happen every day, it is very intermittent to say the least. It could be two days, it could be two weeks. I have contacted Verizon about it and Motorola. Moto sent me a new battery under the assumption that was the problem. Well it wasn't and I just had it happen using the new battery. I really think this is software issue.
Here's what to look for if you think your battery is dying too soon: red light begins to flash telling you to charge it up as it was now at 5% or less. Once plugged it in, do not walk away and make sure the phone doesn't go into standby mode. Watch the charging % jump from 5 to 60 in about 10 seconds or less..
Once this happens there is a chance that it will take longer than usual to fully charge your phone. I had mine sit for 3 hours at the 70% mark before ticking over to 80%.
