Ok I just checked my phone and its been unplugged for 15 hours and now at 40% so I guess that is good, Lol
Sent from my DROID RAZR MAXX
I have my screen brightness set to 20%. Just doing that decreased my screen useage of the battery from 40% to 18%. I do not use any smart settings at this point. I use my phone constantly through out the day. 8am to 11:30pm and have never killed the battery. Closest I came was 20% at the end of the day which was with 3G on the entire day, BT on for 4 hours as well as GPS for 3.5 hours. Push mail for Facebook, yahoo and google on all the time, 90 minutes of cell calls and updating numerous spreadsheets that reside on drop box. Fantastic phone. Glad I did not get the Galaxy Nexus which would have required me getting an extra battery and charger to do what my Razr Maxx does in the same day.
I just received my Maxx yesterday morning around 10am. It came with about 40% battery and I used it non stop from 10am to about 5:30pm before it died. I charged it to 100% overnight and unplugged it at 7am, now I have barely used it at all today and it has dropped to 80% with very little usage, that doesn't seem right to me...I hope it gets better in a couple of days.
Your's sound like mine. I've been working all day with my Maxx on my desk. I checked the battery and its at 70%. I am using Smart Actions- Battery Extender. The signal here at work has always been bad though. Once I go outside or down on basement level its fine. I was told it will get better so I am hopefull!!!
I can easily pull a 15 hour day pushing the battery hard. I couldn't ask for better really. Today is a modest use day (including sleeping for 5 hours) but I am at 20 hours off charge with 51% battery remaining. I have done everything I usually do, just not tons of it. (This is with wifi and 4G but 25% display which is perfect for me unless watching Netflix)
