I have a Nexus 5X
Good: It’s a nice phone. Good features, screen, size etc. I like the finger scanner for unlocking. You get the new software quickly and it doesn’t have weird menus/colours etc – can’t stand Samsungs for that
Bad: Battery life is dire. Runs out about dinner time. Has a USB-C port which while it charges quickly means you need special cables and noone else ever has one you can borrow.
My particular one has a bug where one day the battery meter stuck on 50%. Never changes. Tried everything including hard resetting the phone and doesn’t fix it. With its awful battery life and no idea of how much juice its got you play a weird game of will it/won’t it turn itself off
I did get one app that shows battery voltage on a widget. 4.3v = fully charged. 3.4v = shutdown imminent.
Drop me a line if you want to buy it. It’s green and 32gb and has a wee dent in the plastic on the back.
