I'm building an 18650 phone charger which follows [this tutorial.](https://www.instructables.com/Homemade-DIY-Power-Bank-Using-18650-Battery/)

[![Block diagram][1]][1]

The 18650 battery is connected to the TP4056 module.  Then I have that connected to a boost converter to step up the 2.8V - 4.2V (from the 18650) to 5V.  The boost module has a USB output which I can then connect to my phone.

My problem is that after connecting my phone, I can confirm a correct 5V but it only draws like 60-80mA (confirmed with my multimeter.)

I initially thought maybe I had high wire resistance but it still doesn't draw much current.

What am I doing wrong here?
