I find my tilt sensor a little on the slow side. Sometimes it tilts horizontal when I want it vertical, so I just tilt back and have to wait a few moments. The rest of the phone is responsive and quite rapid. As this is only an occasional problem I can live with it for now. Google Sky Map worked perfectly for me the few times I tried it. If yours is worse than this then it may indicate a hardware/software fault. Depends pretty much on the ROM installed and if it needed the correct kernel applying I guess.
EDIT: Just tried Google Sky Map once again and its working perfectly. My last ROM change on my San francisco II was delete the factory/data, delete both caches, apply the Fish N Chip ROM with Nemus, apply the SanFranciscoIIkernel.zip then and only then reboot the system (phone). Since then I updated the Flash and restored APPS/data from my full version of Titanium Backup. Their is now a version of Fish N Chip that doesn`t need the kernel file applying, this ROM is dedicated to the SFII.
I`m well happy with this phone now, it maintains 4-5 days on power just using the phone (had Flu so I didn`t use it much) and 24/48 hours using a mix of all features and APPS. But I did do some remedial work to clean up the power side and use Power Manager too. I got the phone to 100% charge, opened Restore and deleted the battery stats, let the phone drain to 4% under normal use and only then charged it. So the stats built up to a good spread of data from near flat to fully charged. This may or may not have helped but I`m impressed with the power usage so far.
