Many people often charge their smartphones with their cases still on, but this common practice may be harming your phone’s battery life. The main issue lies in the heat generated during the charging process, which can be exacerbated when the phone case is left on.

Batteries and heat: A troublesome combination

Most smartphones use lithium-ion batteries, which naturally degrade over time as their constituent parts become stressed. Charging your phone excessively or from zero can also shorten battery life. However, overheating is one of the most effective ways to damage a battery.

Apple’s support site warns that using iOS or iPadOS devices in very hot conditions can permanently shorten battery life, and advises against leaving devices in parked cars due to excessive heat. The recommended ambient temperature range for using these devices is between 0º and 35ºC (32º to 95ºF).

How phone cases contribute to overheating

Certain phone cases can cause devices to heat up during charging. If you notice your phone feeling significantly warmer after charging, it might be an indication of overheating, which can damage battery capacity.

Preserving battery life: Simple steps to follow

Taking off your phone’s case during charging is a good first step to help maintain battery life. Additionally, avoid leaving your phone charging overnight, as this can stress the battery’s electrodes. Huawei suggests keeping your charge percentage between 30 and 70 percent for optimal battery life, while Apple offers a feature in its settings to prevent charging beyond 80 percent.

In conclusion, giving your phone a break by removing its case while charging can help preserve battery performance and extend its overall lifespan.
