Your iPhone battery won’t last forever. In fact, after about 400-500 full battery cycles, the capacity of your battery will have decreased by about 20 percent. This is normal, and it doesn’t mean your phone is broken. However, there are a few things you can do to help preserve the health of your battery and make it last as long as possible.

How to charge your iPhone

One of the best ways to prolong the battery life of your iPhone is to charge it regularly. That means, whenever you can, plug it in and let it charge. Of course, you can’t always do that, so here are a few tips on how to charge your iPhone to help preserve its battery health:

-Use original Apple chargers. Off-brand chargers might not provide the right kind of power for your iPhone, which could lead to problems with its battery.

-Avoid extreme temperatures. Both too hot and too cold can damage your battery, so try to keep your iPhone in a temperature range of 32° to 95° F (0° to 35° C).

-Don’t leave it plugged in all the time. Even if you’re using an original Apple charger, it’s best not to leave your iPhone plugged in 24/7. Over time, this can degrade the battery’s performance.

Why you should preserve battery health

Your iPhone’s battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when using the built-in setting to optimize battery charging. Once the battery degrades to this level, you might notice a significant decrease in your device’s runtime between charges. You can help preserve the lifespan of your iPhone’s battery — and avoid unexpected shutdowns — by following these tips.
