Just got my Google Pixel phone, feel excited!Used it for some days, the battery life is amazing. It takes forever to get this Google Phone to fully discharge it's battery. I streamed 1080p HD Video for maybe 3-4 hours, and that only knocked off about 1/3. I then turned the GPS, WiFi, Bluetooth, and Google Maps on and starting zooming all over the world in Satellite mode with the screen turned up to full brightness - trying to stress the phone and the battery. No luck. After leaving it to sit all night, it was still only down to 29%........1 day 21 hours later.But as a crazy Android fanboy dependent on smartphone, I still think it is essential to get an external battery pack for travelling on the go.I searched on Amazon and got one, used it to charger my Pixel, screen showed charging rapidly, max power nearly to 5V/3A with ampere App. Extremely fast, it only takes 70 mins to juice up the phone from empty to full.
