How to limit background process

Limit background processes to improve battery life and performance

If you’re finding that your phone’s performance starts getting a little glitchy at times, you can reclaim control over how your phone operated by accessing the developer options in settings. Here you get to control how many background processes your phone is allowed to perform. Cut them down a bit and you should see an improvement in performance, and potentially battery life too. You can choose the background processes limit right down at the bottom of the Developer Options menu in Settings.
