Why is my battery draining so fast

[eonstein377]

I have a android tablet. Just lately i have noticed a very rapid battery drain on facebook. I have isolated the problem but have not been able to fix it. When i open facebook the main page opens but the column on the right with various ads etc will not open, the load circle just keeps spinning. Battery is flat in less than 1 hour. Have tried uninstalling facebook & reinstalling still the same. Have reset to manufacture. Still the same. This problem was not always apparent. the tablet is 1 year old and has only appeared in the last week. Hope someone has an answer
