- John, I think your confidence is misplaced. My S3 is always set to update when
- I press the System button. My machine also slows down occasionally for while.
- The more CPU intensive your activities are, the longer the slow period. This
- is a separate phenomena to the 'Updating Lists' slowdown. I have always assumed
- , as does steve@geosys.co.uk, that the S3 is performing some sort of garbage
- collection/memory defragmentation.
-
- On a similar subject, I have seen my S3 switch itself on for no apparent
- reason. I think this has been mentioned before, but has anyone spotted any
- pattern to this? More importantly, is there anyone who thinks their S3 does not
- do this? I have seen it happen to several S3s, and I have a nasty feeling that
- if they aren't set to auto power off they will stay on.
-
- Perhaps someone should ask Psion?
