Bose SoundDock/iPhone 4

[tomtendo]

I have a Bose SoundDock that is 2 years old and when I got my iPhone 4, one of the first things I did was see if it charged my iPhone.

It ended up being able to charge my iPhone, however the website actually doesn't show it compatible with my iPhone 4 and I did call them and they said if it says its charging it should be good.

Will having it charge my phone while listening to music harm my battery?

Also, another question - Is plugging your phone in at like 50% or whatever and charging it a little bit than taking it out of the dock bad for it?

(My 2 year old iHome iH9 does the same thing)

No, partial charging is not bad. That was a problem with the old nickel-based batteries. What's bad for lithium-based batteries is regular, deep discharges. You should normally plug it in before it's completely discharged.

The device keeps an electronic "battery meter" that can go out of sync. This can be reset by an occasional complete discharge and then your device will charge to 100% again.
