Right voltage but the phone is discharging!
Hi guys, when i connect the mintyboost with my phone it starts to discharge. Nothing is hot on the circuit and i get the right voltage, 5v, on my multimeter. What's wrong?

Does the voltage drop at all when you connect the phone?Nothing is hot on the circuit and i get the right voltage, 5v, on my multimeter.

I'm using 2 rechargable batteries with 2100 mAh. My phone is an Huawei Ascend G615 which have an 2200 mAh battery. I'm sorry but now i can't do photos. My camera is broken.

Re: Right voltage but the phone is discharging!
Did you try shorting the two data pins together? Most current-generation phones work well in this configuration.

Re: Right voltage but the phone is discharging!
Yeah i tryed to short those 2 pins but it won't charge. But now something strange is happening! I made another board one and i cannot figure out why i get out 2v instead of 5v. Here's my circuit, i thought it was right.... Here's the circuit on eagle http://www.mediafire.com/view/67cmj6k80 ... _boost.brd
