Tips to minimize the battery health degradation on iOS 18

Like other phone batteries, the iPhone battery degrades over time, irrespective of how you use it. However, if you use faster charging speeds, the battery will degrade more quickly, since fast-charging heats up the phone—which is bad for battery health.

Here are a few tips to conserve battery life:

• Use a slower charging speed to maintain a lower battery temperature. This will slow down its health degradation.
• Use the Apple original or Apple MFI-certified adapter and USB-C/Lightning cable. An uncertified adapter or cable may not send the correct voltage/Ampere needed for an iPhone, which will decrease battery health.
• Turn on "Optimized Battery Charging." This slows the charging speed after reaching 80% to extend its life.

Note that you may see a big drop in battery health percentage after updating to iOS 18, which is completely normal. When you install a big iOS update, various components on your iPhone will update and/or refresh, including battery health percentage. Therefore, there's a good chance you may see a drop there.
