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.

Thanks a lot Minho. I have another questions plz :
For example : On Iphone 6 Schemetic Capicitor c1530 , I find 25V.. My question Is :
25V its a max voltage this capicitor support? Or when i check it with multimeter (when my phone is turn on) the value will be 25 Volt?
Thanks Again.

Hello

It means the capacitor max support 25V.

Thank u Palle.. but when my phone is On, which voltage have this capacitor (c1530) if i test it With multimeter ??

Pallle · 09-26-2017, 13:41

With LCD and backlight on: about 15V
Without LCD: about 4V (VCC_MAIN)

Thanks a Lot.. Palle.. sorry for question.. but i m new and learing about reparing

How can i know the real voltage will be..
I explain better. I have a schematic and also ZWX Dongle. Where i found this voltage before verify...?? i mean to say.. how can u know the voltage will be 15 with lcd and 4 without??? thanks

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

umer23mar · 09-26-2017, 16:42

you are great Dude

There is also very number on left and right of voltage value : like :
10 12 14 15 16 17 23 31 39
48 51 52 In the right and in the left : I64 ?? what does it mean..?

On the right, pages where you can find this line.
