You can always have too much of a good thing – this applies to cake as well as charging your phone.

iPhones and Android devices use lithium-ion batteries, which can “theoretically” be overcharged, according to Ritesh Chugh, associate professor of information and communications technology at CQUniversity Australia.

“That can lead to that Security risks for example, that the battery overheats and catches fire,” he warns in a recent report The conversation.

“The good news is that most modern phones have built-in protection that automatically prevents the battery from charging further than 100 percent – ​​preventing damage from overcharging.”

“However, every time the battery level drops to 99 percent (due to apps running in the background), a ‘trickle charge’ occurs.”

Trickle charging is when a device begins charging again to maintain a full state of charge.

In theory, if a phone reaches 100 percent and stops charging, the percentage will eventually drop to 99 percent and charging will begin again.

But this process is terrible for the overall health of your battery.

“trickle charging can wear out a battery over time,” explains Chugh.

“That’s why many manufacturers have control functions.

“Apple’s iPhones offer the ability to delay charging by more than 80 percent.

“Samsung’s Galaxy phones offer the option to limit the fee to 85 percent.”

While you can ensure that these features are enabled on your phone, Chugh recommends avoiding this by not charging your device overnight.

Instead, Chugh recommends charging your phone up to 80 percent and not allowing it to drop below 20 percent to better extend the life of your battery.
