Public bug reported:
When I was travelling recently I found that if I plugged into a USB
battery overnight to charge my phone, when I got up the next morning the
phone didn't have any more power than when I started.
Turns out the reason is: when the phone decides the battery is full, it
stops drawing current. The battery then decides that charging is over
and automatically switches off. The phone then decides that it's been
unplugged and turns the screen on. I had set the phone to not
automatically switch the screen off, so it just left the screen on all
night. The next morning it was as if it had never charged.
So I have the following suggestions:
* Just don't turn the screen on when the user unplugs the charger
* If the intention is to let the user know that the charger has been unplugged,
pop up a message. Just turning the screen on isn't very useful feedback.
* If you are turning the screen on automatically it "doesn't count" wrt the
user's "automatically turn off screen after..." setting. This should always be
just a few seconds.
* If the user has configured the phone to not automatically switch off the
screen, don't automatically turn it on either
* Give me a few more options for automatically switching off the screen - 1, 2,
3, 4, 5 and 10 is a lot of resolution at the low end. Where is 30mins and
1hour?
P.S. this has nothing to do with webbrowser-app but I still can't figure
out how to search launchpad for Ubuntu touch packages.
