Tips to Protect the battery inside your smartphone

Protecting the battery inside your smartphone – be it an iPhone, Samsung Galaxy, Nokia – is key to the longevity of your device.

If you leave your smartphone plugged in and charging overnight, you might be doing more bad than good.

This is according to battery company Cadex, which issued some important battery health advice to ShortList magazine.

It said: “Li-ion (lithium-ion) does not need to be fully charged as is the case with lead acid, nor is it desirable to do so. 

“In fact, it is better not to fully charge because a high voltage stresses the battery.”

In a nutshell, once your smartphone has reached capacity, it will start to administer “trickle charges” to the battery, to prevent it from getting too low

According to Cadex, this can put the battery under unnecessary stress.

To prevent this, you’ll need to unplug your device from the mains as soon as it hits 100 per cent charge.

Granted, this can be a little tough to do when you’re fast asleep.

According to Cadex, the preferable alternative is to charge your device intermittently throughout the day rather than in eight-hour burst overnight.

That’s certainly not as convenient, but the battery firm believes it could help your battery life go further in the long run.
