Do not Let the Battery Drop to 20 Percent

Many people are letting their smartphone battery drop until just 20 percent or less before charging. They think that charging the battery when it still got some power will harm it. Actually, it is totally wrong. the truth is it will be broken easily if we often charge it when the power is dropping to 20 percent. It is better if we do charging when the battery is still at 40 or 60 percent as it will keep our battery’s lifespan.

Use the Original Charger

We often use a charger from the other devices or not the original one when we forget to bring theirs. Sometimes we also use a power bank when we are traveling.  Actually, doing both ways are not recommended since it can harm our battery. In some cases, a smartphone that is charged by a different charger often blow up because the charger is not suitable for it. That is why using the original charger for our smartphones is safer and it the battery will not easily be broken.

Do not Use the Smartphone While Charging

While charging the battery, we often still using our smartphones such as playing games, socializing in social media, and etc. Actually, there is nothing with that. But, it would be better if we let the battery gets recharged until it is full. If we still playing it, we will force the battery to work twice and it will take a lot of time until it is fully recharged. At the end, the battery will be leaked and its power will drain quickly.

Remove the Protective Case

A lot of people are using a protective case in order to protect their smartphone from an impact and to beautifies it as well. And the fact is that people are still using the protective case while they charge the battery. In fact, keeping the case while charging will give a bad effect because the battery will be heated up since the case is blocking the battery to maintain or cooling down the temperature.

Never Leave the Smartphone Charging All Night Long

We must ever experience charging our smartphones in the middle of the night before we sleep but, we often forget to plug it off. As the result, it is charged for hours until the morning comes. This will break the battery itself because it gets too many power and if we do it very often, the battery will get low easily although we have charged it until its full. Then, try not to charge our smartphone when we are about to sleep.
