Check out these charging tips on how you can maximize your iPhone’s battery life.
If you want to keep your current iPhone going for as many years as possible, one of the best things you can do is to protect the life span of your iPhone’s battery.
Battery life span, not to be confused with your battery life, is the length of time your battery has before you need to replace it. The rechargeable battery in your iPhone should work at optimal capacity for (hopefully) a couple of years at the very least, but that depends on a variety of factors, like environmental temperatures, how you charge your battery, drop damage or a faulty battery. ("Battery life," on the other hand, is the amount of time your battery can power your phone before it needs to be recharged.)
If you aren’t quite sure what to do to help prolong your iPhone battery’s life span, who better to advise you than Apple? Below you’ll find a few tips directly from the company that’ll help keep you from having to replace your battery sooner rather than later.
First, make sure Optimized Battery Charging is enabled
Though you can’t overcharge a battery, you can put your battery under a bit of stress when you charge up to 100%. To help limit that strain, Apple introduced a feature called Optimized Battery Charging in iOS 13, the idea being that when the iPhone is hooked up to a charger for extended periods — specifically overnight — that controls the charging so that the device is fast-charged to 80%, with the final 20% added in time for when you wake up.
This can help reduce battery aging, and though the setting should be enabled by default, it’s still good to check if it’s on. In Settings, go to Battery > Battery Health & Charging and make sure that Optimized Battery Charging is toggled on.
Keep your iPhone away from extreme temperatures
If there’s one thing that rechargeable batteries do not like, that’s getting hot. According to Apple, iDevices are good operating in a range of 0 degrees and 35 degrees Celsius (32 degrees to 95 degrees Fahrenheit), and the company warns that using its devices "in very hot conditions can permanently shorten battery life." Fortunately, the fix is simple — keep your iPhone out of hot temperatures. If you’re at the beach, don’t leave your iPhone on your towel in direct sunlight. Instead, toss it into a bag or put a shirt over it for protection. Also, don’t leave your iPhone in the car for an extended period of time, especially if it’s a hot day.
Apple does have a few settings to prevent overheating and damage, like disabling your phone or preventing further charging when your phone is too hot, but you don’t want to rely on these features to save your phone’s battery health. It’s better to take preventative actions than wait for your iPhone to overheat.
You may need to take your iPhone out of its case
If your iPhone gets hot any time you charge it, you may need to take off your case before doing so. Certain cases, especially the bulkier and more protective ones, can trap heat and make the iPhone overheat, affecting the battery’s life span.
Apart from removing the case, consider avoiding processor-intensive apps, like games, when your phone is charging. Using these apps while charging could also cause your phone to overheat.
Take these steps to protect iPhones in long-term storage
Maybe you got a new phone and want to stash your old iPhone for a bit. If you want to maintain the battery’s life span, you should do the following before putting it away:
- Keep the charge at around 50%. You don’t want your battery to be full or empty before you turn it off, or else it could stop holding a charge (if full) or lose capacity and have a shorter life span (if empty).
- Turn your iPhone off. This prevents your phone from using up more battery.
- Store your phone in a cool and moisture-free environment. Ideally, the temperature should be less than 90 degrees Fahrenheit (32 degrees Celsius).
- If you’re putting your iPhone away for longer than six months, turn it on and charge it to 50% every half a year.
If you store your iPhone for a long time, it may be in a low-battery state, which just means you may need to charge it for 20 minutes before it turns on.
