The battery life of our smartphone is a crucial aspect to ensure its performance and durability. Apple, aware of this need, has introduced a feature in its iPhone 15 and iPhone 15 Pro models that allows us to control how much we want to charge our device.
Why limit the charge to 80%?
Lithium-ion batteries, like the ones used in iPhones, have lifecycles determined by charges and discharges. By consistently charging our device to 100%, we may reduce its capacity over time.
Limiting this charge to 80% helps avoid the stress that a full charge can cause on the battery, thus increasing its lifespan.
Unlike previous models, where only the “Optimized Battery Charging” function existed, which intelligently delays charging beyond 80% based on the typical charging schedule, the iPhone 15 has introduced an option that prevents the device from charging beyond 80% under any circumstances — with some exceptions.
How to activate the charge limiting feature?
This feature is especially useful for those who want to have stricter control over the iPhone charging process. The process to activate this charge limitation is quite simple:
- Open the Settings app on your iPhone.
- Go to Battery.
- Tap on Battery Health.
- Enter Battery Optimization.
- Select Limit to 80%.
That’s it. With these simple steps, you can limit the charging of your iPhone 15 to 80%, which, along with other good practices, contributes to better long-term battery health and performance.
Let’s keep in mind, though, that the battery will still occasionally charge to 100% to ensure that performance measurements remain reliable. Except for those cases, and considering that the battery life of the iPhone 15 is longer than any previous iPhone, we now have an additional tool to ensure lighter and more efficient battery usage.
