I realized a while after sending this that I forgot to mention that this 
also happens when the phone isn't suspended, e.g. if it's unplugged from 
the charger while it's still charging.

While the backlight changes within a couple seconds, it usually takes 
closer to ten seconds before the battery indicator adds/removes the 
lightning bolt and the charging LED turns on/off. (Since those happen at 
the same time, I assume they are connected somehow, while the backlight 
isn't.)

If it was locked, it sometimes ends up going back to sleep before it 
turns off the charging LED, which means it doesn't turn off until the 
phone wakes up again for some other reason...

That would fix the part I actually remembered to mention, and (assuming 
they are connected) also the charging indication problem if the phone 
was suspended when charging stopped/started, but not if it was awake at 
the time... I suppose that part might require a second fix though, if 
one fix can't easily handle both cases.

There wouldn't happen to be some event (from the kernel or otherwise) 
that we can listen to for the charging start/stop, would there?
(Since the backlight delay is variable, I suspect not, and that it is 
simply using a shorter timer - but I could easily be wrong.)
