Do you continue to swipe from the android task manager to close apps you do not need anymore?
Do you always waste your time wondering why your battery do not last a bit more?
Well I may not have an answer for the second question but I have a solution!
With OnLock Killer you can select which app you want to kill when you press the lock button on your smartphone! No more wasting time in closing apps!
This app will run a background service which will kill all your "sentenced to death" apps.
Your android experience will not be affected... it will be improved!
This app require ROOT permission but if they are not present OnLock Killer will try to kill your selected apps but the results may not be as well as on a rooted device!
Remember : Use this app at your own risk! Choose carefully which apps you want to kill!
