iPhone Battery Lifespan Dropping? Avoid These Common Daily Mistakes

17 Nov 2025 7:48 PM IST

Smartphone users usually do not realize that their everyday habits may be harmful to the battery life of their phones and that they are unintentional accelerators of battery wear. There are some practices to suggest that can help to get the most out of the battery of an iPhone.

Charging Overnight: A Big No!

When an iPhone is kept plugged in overnight, the battery remains fully charged for quite a long time. The perfect condition for a lithium-ion battery is being between 20% and 80% charge level. Charging at 100% for a long time puts stress on the battery, and this can lead to a gradual decline in the number of effective charge cycles over time.

The Deep Discharge Allowing

The battery lifespan may be affected by the practice of frequently letting an iPhone drop to 0% before charging. The battery is put under stress when it is completely discharged, and if a charge is maintained above 20%, it will last longer. Users should thus connect their device before it shuts down completely.

Using Unauthorized Chargers

There are dangers when it comes to charging the iPhone with low-quality or non-certified cables and adapters in the long run. Such chargers may provide unstable power which might lead to overheating and battery degrading. To guarantee smooth charging, Apple-endorsed accessories are the best option.

Maxing Out the Brightness

Leaving the display on maximum brightness all the time brings about the production of heat that is more than what the battery can handle. This will then lead to the battery losing its charge faster and reducing its efficiency. Therefore, if one cannot lower the screen brightness, they should at least use the auto-adjust setting.

Apps Running in the Background

A lot of apps do their computing in the background and draw power even when they are not actively used. Social media, navigation, and streaming apps are the most common ones that do so. Turning off the background refreshing for those apps that are not essential may lead to a longer battery life.

Heat Exposure

A key element in the ageing of batteries is heat. The iPhone, if left in hot places like the interior of a parked car or exposed to the sun, may have its battery capacity irrevocably diminished. It is recommended that the phone not be used extensively when it is warm already.
