To do that, go to Settings, tap Control Center, tap Customize Controls and tap the green plus sign next to Low Power Mode. Control Center is the menu you see when you swipe up from the bottom of the display. We recommend putting Low Power Mode into Control Center for easy access. You can also turn it on in your iPhone 6s’ settings if you need it before that. If you’re at the 10-20% mark, you should get a prompt that asks you if you want to turn it on. Toggle it on, and you’ll save yourself in critical situations. Best of all, it accomplishes this with one press of a button. Low Power Mode will allow you to stretch out your last 10-20% of iPhone 6s battery life without killing your core services. If you haven’t started using it already, you’ll want to start using the Low Power Mode that Apple debuted with iOS 9. Keep that in mind for future iPhone 6s updates. Battery life sometimes takes a day or two to settle in immediately after a new update is installed. If you just installed a new iOS update, give it a couple of days before drastically altering your settings or habits.

If you can’t find something, you can search for it there. The iPhone 6s’ operating system allows you to search for specific settings at the top of the Settings screen.
