I, as well as MANY others, have the same problem as AntZoo but Microsoft and Nokia appear to not give a crap! Uninstall apps? Why in the world did the update add all these wonderful apps if you have to disable everything to get the battery to last more than a few hours? I charged mine all day yesterday and took it into the bedroom last night. Woke up this morning to a dead battery! Before the update, the battery would last almost two days if I didn't use it hard. THIS IS NUTS! BACK TO ANDROID AS SOON AS I CAN!
