Maybe this was talked about long while ago. But it doesn't look like a common complain here, which is good. I use my Ally mainly as phone/email device and do just about 10 mins of browsing web a day. Under this kind of usage, battery level goes to about 50% after 12hrs from unplugging the charger. With some more browsing, it can get down to 33% easily in 12 hours. I guess it will be dead by 18 hours this way. I wonder how you guys batteries are doing compared to mine. I wish it lasts a bit longer than this.
