Just for posterity, with a wipe and a reinstall as suggested by lappydk
I appear to have solved the battery issues I was having (as reported here
). On wifi with 3G on, calendar, tasks and reader widgets I get about 20 hours. I turned off autorotate based on comments here, but not sure if that makes any difference. With 3G and no wifi I would probably get about 12 hours or so in a good reception area, which is about what I was getting before. My GPS signal is also much more reliable now.
I am still have a couple of problems:
1. Still can't change voicemail number. In the telephony settings, I try to change the setting from the default and press ok, but it reverts back to the default after I press ok.
2. Wifi tethering. If I have 3G on and enable tethering, then take a call, I will lose the 3G network and have to toggle airplane mode to get it back. An even easier way to see this is to have wifi on, enable wifi tethering and see that you won't be able to get on the 3G network.
Can anyone replicate these or have a fix?

One more thing, what is the maximum screen on time that people are getting with CM10.1? (i.e. doing something that isn't too CPU intensive but using screen continuously). I struggle to get more than about 4 hours these days, but using an OEM battery.
