While some Apple fans have been going wild for the brand-new iPhone 15 series, there are still some of us out here just trying to make our older iPhones last as long they can. 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.
And while we’re on the subject of your phone, here are a couple of other CNET stories you’ll want to peruse: Find out everything we expect to be announced at the 2023 Apple Wonderlust event, and check out rumors that the iPhone 15 could support faster charging speeds.
And now, on to the battery tips…
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, 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.
Some cases may trap warmth and cause your iPhone to overheat when it’s charging.
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.
