How to protect iPhone battery health and avoid damage?

You may cause irreparable damage to your iPhone's battery. Here are some daily behaviors to avoid to help prolong the health of your battery.

In every iPhone, there's a series of silicon, capacitors, and little solder joints that are the battery. The battery is a consumable resource that will eventually drain and need to be replaced to continue to get acceptable battery life on your phone.

Ideally, it would take you quite a while to replace the battery. To ensure you get the longest possible life, here are some common things you can do to avoid harming your battery.

It’s getting hotter here

One behavior that can lead to reduced battery health is high temperatures. Heat is the enemy of batteries. Cold is also not a friend of your battery, resulting in shorter usage time, but this is only temporary until your battery warms up again.

Apple says your iPhone can operate safely in temperatures up to 95 degrees Fahrenheit. Beyond this, irreversible damage to the battery may occur.

There are several ways you can unintentionally heat your iPhone to too high a temperature. Leaving it screen-side up to charge in the sun, or clipping it to your car's heating vent while navigating are common moves. Your iPhone does have a built-in protection system that can temporarily disable your iPhone in these situations to prevent further damage, but it's best not to do this in the first place.

Far from Zero

Another behavior that users fall into is lowering the battery of their phone too much. A few years ago, it made sense to occasionally drain your device's battery and then fully charge it to help calibrate the internal sensors so that the displayed percentage was accurate. With modern batteries, this is no longer the case.

Taking your iPhone battery charge down to 0% is very harmful to your battery and will shorten its overall lifespan.

For optimal battery health, charge your iPhone regularly throughout the day so you don’t completely drain it.

Long-Term Storage

If you are going to store your phone for a long time, please do not keep the battery at 100%. Maybe you keep your old iPhone around to use as a backup or save for later use.

Before storing iPhone, discharge the battery to between 50% and 80%. Come back periodically and make sure the battery has not been discharged to the point of death.

Charging your phone fully is also harmful to the battery. When you return your device for service, you may find that the battery no longer holds a charge as well as it once did.

As long as you avoid these very basic actions, you can keep your battery healthier and longer. Many things can also affect battery health, but the effects are small and won't have a noticeable impact in the long run.

Be careful, your battery will be stable for 18 months to 24 months, and then the charge will drop below 80%. Luckily, when it's time to replace your battery, Apple offers affordable replacements.
