Daily 习惯 to Make Your iPhone Battery Last Longer

Fri, 29 May 2026 11:00:00 +0900

iPhone batteries are consumable parts. After a year or two, most people notice they don’t hold a charge like they used to. The good news is that small changes in how you charge and use your phone can dramatically slow battery degradation.

Understand Your Battery

iPhone uses lithium-ion batteries. A few key facts:

Keeping the battery at 100% or 0% for extended periods accelerates wear
Heat is the #1 enemy (anything above 35°C / 95°F is dangerous)
Apple rates the battery for roughly 500 charge cycles

Check your battery health in Settings > Battery > Battery Health & Charging. If Maximum Capacity drops below 80%, it’s time to consider a replacement.
