I'm still conducting more tests, but we wanted to give you some of my preliminary results.
Day 1
I took the RAZR Maxx off the charger at midnight and it sat idle for 8 hours. I was sleeping so I can’t verify, but it should’ve been on 4G LTE most of that time, but it could’ve switched to 3G periodically. It lost 20% during these first 8 hours, and by the time 24 hours rolled around, it still had 5% left. I would say it wasn’t a heavy day as far as usage. I played games for a couple of hours and streamed Slacker for maybe 40 minutes. The display was on 20% of the time or about 5 hours. The display was set to automatic brightness, but I realized late in the day that the GPS wasn’t turned on. Bluetooth was on (but rarely connected) and WiFi was off. All in all, I would say the battery performance was superb, but I decided to work it a little more for day 2
Day 2
GPS on, Bluetooth on (rarely connected), Wifi off, and Auto display off and turned up to about 2/3′s brightness. I took it off the charger at 7:00am and by midnight (17 hours later) it had 5% left. A lot less, but I did a lot more with it. Other than doing a little gaming and Slacker again, I played 4 hours and 15 minutes of video. The display was on a total of 42% of the time or a little over 7 hours. It was mostly connected to 4G, but some 3G was probably thrown in. 17 hours is tremendous considering the amount of video and the fact that the brightness was set fairly high, not to mention it wasn’t officially dead yet. It might have lasted another 2 hours with light usage.
Motorola has really changed the game with the DROID RAZR MAXX. At 8.9mm thick and a 3300mAh battery, no competitive phone comes close. The DROID RAZR MAXX is the only phone I’ve used in which I don’t need to panic when it’s down to 10% remaining battery. It could easily go another 3 plus hours with light usage.
