Okay, I don't know how this is happening. Just got my X, battery came at 70% and I charged it to 100% (only took about an hour) before playing with it. Battery life on all of my droids has always been pretty bad so I wasn't surprised when it was at 20% after about 4 hours but I hoped it would improve since that was its first charge. Then I drained it completely until the phone shut off.
Plugged it back in and charged fully, then took it off the charger at 11:20 am yesterday (Thurs). I didn't use it much, but a few people played around with it at Thanksgiving, it was still at 80% when I went to bed last night, 12 hours later. Fidgeted around with things again today for about 45 minutes, and now, 24 hours later, it's still at 50%!! (I have it on the nighttime saver setting, not even the maximum).
I'm so surprised I'm starting to wonder if the battery manager is accurate...lol
That does sound very good. It seems that the DX has great battery life. As you mentioned it does all depend on how much you use it. I could go all day (15hrs) and only be at 70% if I hadnt used any 3G but was only texting and calling.
From the newness of your battery, it should only get better still.
Anyways welcome to the Droid X family. You will love it here.
I dont use any of the moto blur crap, that seems to eat up a lot of battery. I have the screen on min brightness and use wifi when ever I can, other then that I dont do anything special. Weather app refreshes every 2 hours, facebook I update on my own (plus I get email notifications)
