When you are tired all day and ready to go home, you suddenly find that the battery of your mobile phone is only 5%, and this amount of power cannot support you for the next up to an hour. So, at this time, will you choose to stay and recharge before leaving, or bite the bullet and leave? I believe that there is no need to say that more than 90% of people will choose to stay and charge their mobile phones to a range that they think is safe. This is "battery anxiety disorder" .
