I think we will improve this a small amount in kernel updates we already know we can do, but how much I don't know. We already know we waste current with bad GPIO levels in suspend and can fix them (I have a list here to do). Also I "derated" these estimates somewhat just in case since I did not verify them.

I personally don't know this yet, but people are starting to use the frerunner A5s here as real daily phones, so there will be a feeling about this soon. But much more (software) work is needed to make suspend totally reliable and trivial to do all the time, which will alter the figure for this scenario hugely. So I would advise not to expect great battery life at the start, but that it will very likely make great improvements as the software matures (since we took some care about the hardware side to allow it). - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFHygrGOjLpvpq7dMoRAq44AJ9Hhq7MPchmkvB98Zejd+MJSD2mGQCeNdzF Bco/d0u0kFe37WN8+QEXq2o= =qjcE -----END PGP SIGNATURE----- _______________________________________________ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
