This might come as a shock, but most of you have been charging the phones and tablets the wrong way.

You must have heard or read on WhatsApp about phone on overnight charging blowing up causing injuries to the user while the person was asleep.

Don't worry, overnight charging wouldn't do that to your phone. But it is also not recommended, according to the findings of Cadax , a company that offers devices that test smartphone and other batteries.

Battery University, which is run by Cadax, suggests these tips to improve your phone's overall battery life:

Charge for shorter duration

It doesn't matter if you only charge up 10 per cent or 20 per cent as, according to Battery University: "Partial charges cause no harm."

Don't hit the red zone

Also, if you want to lessen the wear and tear to your battery, do not hit the red zone, which is 15 per cent in most of the phones.

Try to keep the device between 65 per cent and 75 per cent -- "the sweet spot", according to the website.

Use a power bank

If you don't have a desk job and have to travel a lot, invest in a power bank.

Never charge your phone up to 100 per cent

The experts have also recommended that never ever, never ever, never ever charge your battery fully.

Try to keep it around 95 and you are good to go.

Today's modern lithium-ion batteries do "not need to be fully charged, nor is it desirable to do so.

The website states: "In fact, it is better not to fully charge, because a high voltage stresses the battery".

You don't need to remove the charger when it's full

Yes you are right.

But, if it so happens that you have left your phone on charging and it has hit the cent per cent mark, then the charger, according to the website, will automatically turn off.
