What really bugs me is the way the battery usage can mysteriously speed up overnight. For instance, last night before going to bed the Settings told me I had 12 hours left on the battery. It went flat in less than 6 and I missed my alarm call.
IMVHO it seems to me to be a failing of the Fairphone that it has to remain on all night to work as an alarm clock. Whereas with my old Nokia I could set the alarm and switch it off, and it would automatically switch on with the alarm.
I don’t know how to reproduce the battery usage chart here, but here are the stats:
Screen 10%
Wi-Fi 9%
Email 8% (this is the generic app, which I have abandoned in favour of Outlook: Emails from Fairphone haven’t been sent )
Phone idle 3%
Google Services 1%
Mobile standby 1%
Android OS 1%
…which leaves 67% unaccounted for!
