As a long time Android user and current pixel owner I wonder about how well Android does with degraded hardware. My Pixel has not only gotten slower and slower but the battery life is horrible. Yes, I use the phone all the time but it's really bad. Aside - I wonder if the crappy boxer email app required by work is a source of pain. I don't see iPhone user's charge their phones as much as I do, or carry around an external battery pack like I do.
