Well i'm just testing different use cases now. I fully charged last night. light was green. took it off the charger, set it to 2g only and turned off wifi. checked battery, said 95%. Used the device for about 60 minutes, installin and uninstalling some progs. turned wifi back on for a few minutes to install some bigger packages, then back to 2g. rebooted the device once. chatted for 5 mins on msn. went to sleep and left it with gtalk, skype, msn signed on. also left e-mail every 5 mins, and omweather every hour, although for some reason omweather says it was last updated 6.5 hours ago just now.? looked at it just now 12 hours later, and the battery is at 46% what do you guys think?
