Apple provides 4 ways to extend iPhone battery life.

Battery life refers to the amount of time a battery can be used before needing replacement. iPhone batteries typically last a long time, but this depends on ambient temperature, charging methods, damage from drops, or battery defects.

If you're unsure what to do to help extend your iPhone's battery life, here are four tips from Apple that will help prevent your iPhone from needing a battery replacement sooner.

First, the iPhone battery can be "stressed" when charging to 100%. To help mitigate this, the iPhone has a setting that learns from the user's daily charging habits, such as always plugging in the phone before bed and then unplugging it in the morning. The device will then wait to charge to 80% until just before you need it, instead of trying to quickly charge to 100%.

This can help reduce battery aging. Although this setting is enabled by default, you should still check if it's turned on. Go to Settings, select Battery > Battery Health & Charging, and make sure Optimized Battery Charging is enabled.

Apple claims that its optimized charging feature helps extend the battery life of iPhones.

Next, limit your iPhone's exposure to high temperatures. High temperatures accelerate the chemical reactions inside the battery, forcing it to work harder and faster, which leads to faster battery degradation.

According to Apple, it's important to avoid exposing your iPhone to temperatures higher than 35 degrees Celsius to prevent damage. If you're at the beach, don't leave your iPhone in direct sunlight; put it in a pocket or under a jacket or hat for protection. Also, avoid leaving your iPhone in a car for extended periods, especially on hot days. Apple also has several settings to prevent overheating and damage, such as turning off the phone or preventing the iPhone from overheating while charging.

If your iPhone gets hot while charging, you should remove the protective case before charging. Many users prefer a slightly bulkier case for better device protection, but this can trap heat and cause the iPhone to overheat, affecting battery life.

If you've bought a new iPhone and want to store your old one away but still maintain battery life, Apple recommends charging it to around 50%. This is because a full charge will stop the phone from charging, while a completely depleted battery will reduce its lifespan. Additionally, you should turn off the phone and store it in a cool, dry environment. If you're storing your iPhone for longer than six months, turn it on and charge it to 50% every six months.
