it wont charge past 50% and it takes hours even to reach this. also when i come on here or facebook i have to log in everytime. both problems seam to have started at the same time. are they connected?

Have you loaded any new apps or updated any existing ones?

i put on a new app the other day to rotate my screen but didnt like it so took it off. also got spotifiy. all my normal apps update automaticly

Bit of a nightmare but try a full reset??
