How Can You Tell If Your iPhone 6S Battery Needs Replacement?

You can tell if your iPhone 6S battery needs replacement by observing signs such as rapid battery drain, unexpected shutdowns, decreased performance, and swollen battery casing.

Rapid battery drain: If your iPhone loses charge quickly compared to when it was new, especially during light usage, this may indicate the battery’s capacity has diminished. Apple states that batteries naturally degrade over time, typically losing around 20% of their performance after 500 complete charge cycles.

Unexpected shutdowns: Your iPhone may turn off suddenly even when the battery indicator shows charge remaining. This occurs because older batteries may fail to deliver the necessary power for the device to operate, particularly during demanding tasks.

Decreased performance: If your device runs slower or apps crash frequently, this could stem from an aging battery. In 2017, Apple acknowledged implementing a feature that reduces performance to prevent shutdowns in devices with aging batteries.

Swollen battery casing: A physically damaged battery may swell, causing the screen to lift or become unresponsive. If you notice this, you should address it immediately as it poses safety risks. Apple advises against attempting to remove the battery yourself.

If you experience these symptoms, it is advisable to have your battery evaluated or replaced by a professional. Regular maintenance can prolong your device’s lifespan and performance.
