This is annoying me so much. I swear I charged my battery to 70% took it out, by 1 hour of using it my battery just decreased to 35%! Why? I have to charge it every 2 hrs or just use it and keep in the charger.
Has anyone experienced the same? Is there a way to increase battery life?
And if this helps, my iPhone is actually jailbroken. But ever since I updated to 5.1.1 my battery has been a total nightmare.
Thank you (:
