Many people are charging their smartphones the wrong way.

Business Insider summarizes advice from Cadex - a company specializing in providing battery evaluation tools on electronic devices - for smartphone users.

Charge your battery whenever you get the chance.: Plug your phone in for a few minutes at a time. These small charges won't affect the battery's lifespan, and will help keep it at a healthy level.

Don't let the battery run out before charging.: Many people try to use their phones until they have only a few percent battery left, or even turn off, before plugging them in to charge. This habit is not good for battery life.

Always keep the battery at 65-75%:Batteries last longest if kept between 65% and 75%, so it's recommended that users regularly charge their phones as soon as possible.

The second ideal level is 25-75%: It is difficult for users to ensure that the battery is always around 65% to 75%, however, the battery should not drop below 25%.

Never fully charge, especially when starting at a low capacity:When the phone battery is below 25%, if the user charges it to 100%, it will reduce the capacity and shorten the battery life. In general, in any case, charging to 100% is always harmful to the battery.

Do not charge overnight: As mentioned above, you should never charge your battery to 100%, so charging overnight is a bad habit.
