I honestly can't believe the complaints about the Inspire battery. Granted I am coming from the Captivate and well, 6 hours max of battery life was just unbareable, but I can get over 12 hours or more on one charge with my Inspire battery with moderate use. I took my phone off the charger this morning at 7:10 am. It is now 9:44 PM and I am still rocking 58%.
Now, let me say that I have had very very lite use of the phone today, exactly ZERO phone calls, 2 SMS received messages, background data sync turned on for Twitter and Facebook, and just 80 exchange emails. I also have had WiFi on all day since I have been home a bit under the weather except for one trip to the store.
As a test, I also had my captivate on all day with basically the same settings, minus the emails and SMS messages. The battery on the Captivate died at about 7.5 hours. (about 5%)
I am starting to believe that some of you have received crappy batteries. I have read some many complaints on the battery life on here and XDA forums that its hard to believe.
I am getting the Atrix tomorrow. I am going to decide which phone I am keeping in the next week or so. If I decide to return my Inspire, I am willing to trade batteries with someone having issues with theirs before I return it so maybe someone can improve their experience. Of course, I would need you to send me yours so I can return my Inspire properly.
