The iPhone 6s and 6s Plus were designed to offer up to 14 and 24 hours of usage respectively, all thanks (according to Apple) to iOS 9's intelligent power consumption. But if yours doesn't managed, it could be because you have your settings all jacked up.
iOS 9 has added several new features that are switched on by default, and thus there are settings you can tweak to make your new iPhone go all day. By the time you've made your way to the end of this article, you'll be surprised at how long the battery can actually last.
You know what they say - every little helps.
Not using Low Power Mode
Low Power Mode is the most miraculous part of iOS 9 for people who want to stretch out the battery life of their iPhones. Pre-iOS 9, you could only pathetically look on as the low battery warning flashed up on your iPhone and power seemingly dropped all the way down to nada in a matter of minutes.
Do this instead: When your iPhone’s battery levels dip dangerously low (20 percent emergency bells), it will automatically prompt you to activate Low Power Mode. Do it and your battery will change from red to yellow. You don't even need to wait till you're down to 20 percent; should you expect a long day ahead, you can activate it at any point without crippling your phone. Just go to Settings, Battery, and tap that Low Power Mode. You’ll be surprised at how long your iPhone can last when it dials down its more power-sapping functions.
Not staying in Low Power Mode
Having said that, Low Power Mode is at your disposal 24/7. But when you start charging your phone when it's in Low Power Mode, it will automatically turn it off when battery is charged to 80%. You don't have to let your iPhone call the shots, and can stay in Low Power Mode for as long as you like.
Do this instead: When that Low Power Mode Turned Off notification shows up on your lockscreen, just swipe to the left to hit Enable Again. So you don't have to remember to enable Low Power Mode later.
Oversharing your every move
iOS 9 brings with it the ability to share your location with your friend in Messages via the little Details tab. It’s a pretty neat feature, but you don’t really need it switched on all day so your friend can track your every move, right?
Do this instead: Go to Settings, Privacy, Location Services, and Share Location From to disable it. Or choose to share your location from another device which has better battery life - your iPad for instance.
Being hands on with Handoff
This new iOS 9 and OS X El Capitan feature presents a world of convenience by allowing you to move seamlessly from iThing to iThing - you can start writing an email on your phone and then finish it off on your MacBook, for instance. But if you only have an iPhone, it’s not exactly a feature you can make the most of, right?
Do this instead: Hit up Settings, click on Handoff & Suggested Apps and turn off Handoff. Enable it when you have more battery, get more than one iThing, or actually require the function.
