irst off, I love my Evo and it has been relatively problem free with one exception, that of a very poor battery life. With modest use I would get about five hours before it is completely dead. I have tried most of the battery life tricks and applied the latest software update (successfully the first time) all to no avail. Every night, i plug in my phone at about 12 AM and take it off the charger at about 8 to go to work. I noticed that almost immediately or at most within a few minutes, the percentage drops about 10 points. I usually charge it back to 100 percent but the rapid decline to total discharge during moderate consistently persist. However I was so tired last night that I was unable to charge my phone overnight. This wasn't a concern since I knew that I was at about a 90% charge and would probably be close in the morning. When I woke up, I figured I would put the phone on the charger while I got ready, it wouldn't be at 100% but close enough I guess. I got ready and took the phone of the charger showing 98% at exactly 7:30 AM. I get to work and have sent about 7 texts, being playing with the phone awhile. At about 9:30 the phone is showing 97%. I am thinking hmmmm....but no biggie. At 11 AM it is showing 96%. I actually sent a few more texts and scrolled through some emails. While at lunch, I check the phone and at 1:15 PM, the phone is showing 92%. Normally with the way I had been using it, it would have been in the low 70s or even 60s. Then it hit me. However this baterry is calibrated or the phone is reading the battery, I dont think that WE ARE SUPPOSED TO CHARGE THE PHONE BEYOND A FULL CHARGE. I remember similar posts but I dismissed them as hogwash until I have seen it for myself. Its weird but apparently true. In the month that I have owned this phone I have never seen my battery perform like this. Anyone else can confirm my theory or add further clarification? Just check my percentage at 1:37Pm and it is at 90% after 6 hours off of the charger. That's an 8% decline in 6 hours; interesting to say the least. I am truly excited! UPDATE: GOT OFF WORK AT 11 PM. AFTER 14 PLUS HRS, BATTERY READS 82%. NORMALLY IN WOULD HAVE BEEN 20% OR LOWER.
