All battery related data could be important for user-space.  For example
time-to-full could be shown to user on the screen or health could be
monitored for any issues.  Instead of comparing few selected old/new
values, just check if anything changed in the cache.

At least some value will change every time we poll the battery, are we
okay with having power_supply_changed() called every time?

I believe that's very bad idea. AFAICT that would wake up userspace every
5 seconds, eating power in unexpected way, and without easy ability of opting
out. IOW a regression.
