I could be wrong but I'll take a guess that you mean how to get better battery? You could have a play with your settings to automatically shut down apps which haven't been used in a while or restrict some from using background data completely, which would both save battery. You could also change your screen settings to a lower resolution. I won't go into too much detail as I'm not entirely sure that's what you meant. But if it is and you need more help let me know
