My DX2 suddenly sucks for battery life. This morning I took it off ther charger at 100% and used it for 20 minutes looking at twitter. I got the 15% remaining message and 2 minutes later I get the 5% message and it immediately shuts down. I go to plug it in and the larger battery graphic comes up (the one it shows when you are charging it while it's off). And it says 80%. So I unplug it and turn it back on. Once it went through it's boot up and aquired signal and all that, my battery widget shows 50%. I plugged the charger back in and in about 10 minutes, it said 60%. A couple days ago, I left the house with 90% and turned on GPS and navigation. I got 8 miles from my house and it shut down due to dead battery. Is the battery going bad or is something else the issue. Whenever I check the battery usage, it either shows DISPLAY or IDLE as the number one battery user.
