Does the FP2 have a little cell battery like the FP1?

[Stefan]

Continuing the discussion from FP2 kills some SIM cards:

The FP1 has a little cell battery, which is in charge () of advancing the clock, when the normal battery is taken out of the phone. Unfortunately this cell battery went dead after only about a year for most of FP1-owners and there is no way to replace it.

This story is about the FP2 though:

@tkos

I […] tried to switch off and let the battery out of the phone for some time. …by the way, ther seems to be another bug: i switched back on the phone […] and i was hours back in time.

Actually I think this is not a bug but expected behaviour. If you remove the battery, the FP has no way of advancing the timer, so inevitably the clock will be off the first time you start.

Is this true? Does the FP2 indeed not have a cell battery to help keeping the phone’s clock up to date?
