(assuming the claims on the site are correct, since I have no first-hand data on it) You really don't get that some people think apps like alarm clocks, sleep tracking, GPS logging, ... are useful and should be allowed to run if the user chooses them? To me, a phone that can't reliably run an application for a few hours is fairly useless.
My alarms go off just fine (although I vaguely remember it not going off once or twice a few updates ago), my activity tracker works fine[0] and syncs periodically. I don't use GPS constantly. Signal notifications were also delayed a few updates ago, but now everything runs smoothly.
I find it a worthy sacrifice to make for a sturdy Android One phone with solid performance and a battery that can last two days on medium usage. My activity tracker lasts weeks without charging (comparable to a Kindle).
[0] Worth pointing out that my activity tracker was also developed by Nokia (before they've sold their health division to Withings), so it may receive some special treatment.
I read a comment on Reddit [0] from a Nokia user that had a large file transfer using Solid Explorer killed twice because he left the phone unattended and the screen shut off. It worked when he kept the screen on.
Would you mind testing if background file transfers work as standard and with manual battery optimization whitelisting?
This is the best thing for me. Iam fed up of the notification loop of apps that I have to eventually delete.
Thank god for telling me to buy a Nokia next time.
