Holding On to Your iPhone for as Long as Possible? Make Sure You Keep Your Battery Healthy
We may be gearing up for the iPhone 16 reveal, but not everyone is in a rush to upgrade their phone. You probably won't miss out on many new features if you already have an iPhone 15 or iPhone 15 Pro, and even devices that were released in 2018 -- like the iPhone XR -- will be able to enjoy the new iOS 18 update. If you do want to keep your iPhone as long as possible, one of the best ways (along with getting a good phone case) is to protect and maintain the health of your device'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.

And now, on to the battery tips...
First, confirm that 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, your iPhone has a setting that learns from your daily charging routine (say you always plug in your phone right before you go to bed and then unplug it in the morning). It then waits to finish charging past 80% until right before you need it, instead of just quickly charging the battery all the way to 100%.
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
The life span of your iPhone battery can be affected by extreme temperatures. A higher temperature increases the speed of chemical reactions inside the battery, which forces the battery to work harder and faster, thus also causing it to degrade faster.
According to Apple, it's important to avoid exposing your iPhone to temperatures higher than 95 degrees Fahrenheit (35 degrees Celsius) to avoid permanent damage. 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 might 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.
How to protect the batteries of 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.
