How do I check the battery charge cycles?
I've got an iPhone 4s, and I need to check how many charge cycles the battery has, as I think the capacity has degraded.
Is dit een goede vraag?

One of the easiest ways is using CoconutBattey from a Mac via a USB cable. That what I’ve used through the years.

I replaced the battery without checking the full charge capacity, but now when I installed 3uTools, it turned out to have 20% of the original capacity. That's less than my smartwatch.
@zizmys - So you got a bad battery then?
@danj The replacement battery works normally, I just temporarily put in the old battery because I wanted to see just how bad it was. It could shutdown at 60% when opening the camera.
