So my phone is acting really weird. When i go to plug it in to charge either from a wall outlet or my computer, it says its charging but when i unplug it it, the battery bar has no bar left in it. It was charging fine up until yesterday but now it says that the phone is about to die even though its been on charge for 12 hours. Has anyone had this problem and do i need to take it back. Its very agrivating cause i really was liking my focus and the WP7 hardware.
