The reason is that the sensors are sometimes programmed to read 100 percent as FULL capacity, but if you start using it at 70% it may send a message to the system that 70% is the optimum, so anytime the battery gets to 70% it will indicate FULL and you won't be getting complete value for money.
That's why the manufacturer will always indicate charge before use. Just say calibration.

All these kids on Nairaland, I am engineer with several years experience, this is the most basic thing you should know, for you that knows so much about Tech.

Personally I don't think it is compulsory. I think it's just a gimmick by the sellers and manufacturers, looking for someone to blame if the device doesn't work well. How can you tell me to charge my power bank for 24hrs before use? Would I be buying a power bank if I had 24hrs electricity?

vickthourh:
Charge wetin..

It's not compulsory

RaymondHarmony:
After buying a new phone or power bank, why is it compulsory to charge it first before using it ?

Its also called calibration

Sermwell:

Nobody tells you to charge for 24hrs! Stop lying

Do you think the white Man that manufactured the phone and advised that you charge it to 100% before usage is a fool? Smh.

The problem with Africans is that we don't learn, we don't listen and we feel we know too much. But truth be told, we know nothing.

I have come to understand that whatever these White people do, they have a valid reason for it. There are some things you may think doesn't make sense, find out well, you will notice there is a reason for it.
