I'm trying to test how much power my phone is using by using a multimeter to test how many milliamps it is pulling. I have the battery removed from the phone and all three terminals wired into their respective places, I then intercept the positive terminal with my multimeter by placing the positive lead on the positive terminal of the battery, and the negative lead on the postive terminal of the phone. I then start the phone, it registers about 200 or so milliamps for a couple of seconds, and then just before the screen would light up, it rather quickly drops to about 75 milliamps, then nothing, and the phone never starts. I know its not the wiring because if, using the same set up, I connect the positive terminals directly with no multimeter then it starts up fine.
What could be causing this? What could I change so that I can test the idle power draw of the phone? Or can someone tell me the idle power draw of the phone?
I want to know because I want to put some solar cells on the back of the phone, along with some diodes and a overcharge protection chip all wired to the battery, to charge the phone. But I'm worried the 90mA my cells would put out would not be enough to effectively trickle charge the phone.
Any ideas? Also if anything needs clarification feel free to ask
