Chosen Solution

I bought a Pixel 3 XL that won’t charge (for 45 USD) in hopes of repairing it. Nothing happens when a wired or a wireless charger is connected and I need to know if it’s the battery or the motherboard before I buy a replacement battery.

On Pixel 2 and Pixel (2016 live ), if you see a red light, your battery is fully discharged. If the red light is flashing, there isn’t enough power to turn on. Charge your phone for at least 30 minutes before you restart it.
