How much battery power is left in a mobile phone when charging it?

As more and more mobile phone software is used, the standby time of mobile phones is getting shorter and shorter. In the past, a fully charged mobile phone could be used for three to four days, but nowadays, many people need to charge their mobile phones once a day, and some even need to charge them once half a day.

Therefore, many people now have such a question: how often should a mobile phone be charged? For this question, we should not judge by how often a mobile phone is charged, but we should shift the question to how much power is left in the mobile phone before it is best to charge it.

For me, I think it is best to charge the phone when there is 10% battery left. We all know that every mobile phone has a battery protection mechanism. When the battery is low, the phone will automatically prompt us that the battery is low and please charge it in time. At this time, the battery will be in a protection state. When the battery of the mobile phone is less than 3%, the phone will be forced to shut down to protect the battery of our mobile phone.

Therefore, we can estimate how much power is left in our mobile phone battery according to the battery protection mechanism of the mobile phone, and it is best to charge it once. For many mobile phones, it is enough to always keep the battery level of your mobile phone above 10%. This can ensure that our mobile phone battery does not work when it is low on power, thereby extending the battery life of the mobile phone.

Of course, when charging the mobile phone battery, the power should not be too high. Keeping the mobile phone battery in a fully charged state for a long time will accelerate the internal aging of the mobile phone battery, and eventually lead to worse and worse battery performance.

For our mobile phone batteries, the most ideal state is to keep the battery level between 10% and 90%. Therefore, if you want to charge your phone, just keep it within this range.
