General Information About mobile phone Capacitor


HI Everybody. Sorry for my bad englsh
I have some question plz :
When i want to check voltage in Iphone Capacitor.
I connect the battery and Turn on my phone and then use multimeter
Or Only connect battery without turn on mobile phone?
The battery will be fully charged or its sufficient 10-20% Charging?
Its not risk to damage phone, if i check the voltage and the phone is ON??
Thanks a lot.

That depends what part of the circuit you want to check. Some functions will only activate when the phone is "tunred on". As for the battery, whether it's at 20% or 100%, it will still output sufficient voltage and current for the phone to operate.

Whenever a phone is powered, you always have to be careful when probing with your multimeter as you can easily cause shorts between two adjacent components.

On the schematics Voltage Properties section.
This is what it says 22V, but in reality it's not so much to be.
