Tip 1 of 37: Tips for keeping your iPhone or iPad’s battery running all day
One of the inescapable truths of modern technology is its penchant for regularly sucking from the national grid, like some kind of crazed electronic vampire. You might consider your iPhone or iPad to be the most amazing technology in the world, but they’re little more than metal-and-glass slabs when out of juice. Thankfully, it doesn’t have to be like that.
In this giant tutorial article we’ve got some brilliant battery-saving tricks and tips that will help you keep your battery running all day long, whether you’re on a tiny iPhone 4s or a massive iPad Pro.
These tips will also help you to get your iPhone to last a little bit longer when you’re away for the weekend without your charging cable; during a power cut; or when you’re pootling along on a slow train, trying to coax your iPhone into surviving what would otherwise be a long and boring journey home. Follow these tricks to give your iPhone, iPad or iPod touch enough power to last those crucial extra minutes – or even hours.
Bear in mind, of course, that there might be something wrong with your iPhone’s battery. In 2014 Apple recalled a number of iPhone 5 units, after it determined that some iPhone 5 batteries were faulty, and in November 2016 it announced a free battery replacement programme for the iPhone 6s.

Assuming that’s not the case, here are the best ways to improve your iPhone or iPad’s battery life, from system-wide settings worth tweaking to third-party apps that you should stop – or start – using in order to preserve battery life. We’ve updated this article for iOS 10, but many of the tips work for iOS 9, iOS 8 and iOS 7.

Step 2 of 37: Improve iPhone & iPad battery life: Don’t bother quitting apps
Let’s start by dispelling a battery-saving myth.
iPhone users tend to quit apps we aren’t using as it seems like a logical way to stop them sucking away at the battery. (To quit an app, double-tap the Home Button and swipe up on the app you want to close.)
But apparently, this isn’t such a good idea after all. Apple Store Genius Scotty Loveless explains that when you close an app you take it out of RAM, this means that when you open it again the iPhone has to load it back into memory. “All of that loading and unloading puts more stress on your device than just leaving it alone,” he writes.
Indeed, Apple itself – in the person of software chief Craig Federighi – has confirmed that closing apps doesn’t do anything for battery life.
Tim Cook was asked in an email, “Do you quit your multitasking apps frequently and is this necessary for batter life? Just wanting you to put this controversy to rest!” And Federighi stepped in to reply “I know you asked Tim, but I’ll at least offer my input: No and No.”
Loveless adds that our fears that apps are draining battery life even when we aren’t using them are unfounded, as they will only update in the
Step 3 of 37: Improve iPhone & iPad battery life: Turn on Low Power Mode
In iOS 10 (and iOS 9), there’s a feature called Low Power Mode that reduces overall power requirements and makes your battery last longer. Apple claims the mode will allow you to gain three extra hours of battery life from your iPhone.
Low Power Mode isn’t a default option that happens automatically in the background. It will be offered automatically when you hit 20% remaining power: you’ll see a warning flash up and the option to turn on Low Power Mode. Do so and you will notice that the battery indicator turns orange rather than red (or the green it would be if you had plenty of power). The mode will be switched off again automatically when you charge past 80%.
Over on Birchtree they have run tests and found that “on average, my battery was at 17% at midnight in normal mode, but 49% in Low Power Mode.”
If you want, you can enable Low Power Mode without waiting for your iPhone to reach 20%. Go to Settings > Battery and turn on Low Power Mode.
When Low Power Mode is on it will reduce power consumption, stopping Mail fetch, Hey Siri, background app refresh, automatic downloads, and some visual effects. We actually have all those features turned off on our iPhone already, and yet the Low Power Mode still seems to have an effect.
background if they are set to in Background App Refresh.
“Unless you have enabled Background App Refresh, your apps are not allowed to run in the background unless they are playing music, using location services, recording audio, or the sneakiest of them all: checking for incoming VOIP calls, like Skype. All of these exceptions, besides the latter, will put an icon next to your battery icon to alert you it is running in the background,” he explains.
