i alrleady hit thanks to the people who answered my questions about the kernet thingy. now i'm asking again on how to prevent my battery from draining so fast? i only installed DU Battery Saver (only app i installed) on my phone but every 2 or so minutes, my battery is draining by 1%. last night i charged it to 100% (without apps running in the background), and when i woke up in the morning its already 90%. what should i do?
