I can vouch for doing a "clean" install to fix battery life issues.
Its a PITA getting the apps you want again.. but write down the important ones first. I didn't let google restore either. And the only thing I did restore from Titanium was only the data for angry birds.
My issues seem to have been resolved. Tho I haven't had a "normal" day yet. we'll see tomorrow.
Seems to be working fine... sounds weird.. but could you install focused again without wiping data/cache to see if that makes a difference?
Did you quote the wrong post? lol I thought of that tho. I'll give it a try.
Only "mods" that I've done are blue juice for 1.6 and a couple meta morphs ill give it a go and see what happens.
