Indeed.
I was running update-cm-7.1.0-RC1-V9-KANG-signed-20110717.zip for three or for months and with Airplane mode turned on and tablet just laying untouched I was loosing like 5% (or less) percents of battery over 24 hours.
Finally my tab gone crazy, so I did a full wipe and installed update-cm-7.2.0-RC0-V9-KANG-signed-20111129.zip a few weeks ago. Now I'm loosing 50% of battery charge over 24 hours (same conditions, no tasks running, airplane mode). Battery usage stats over such period are showing "Phone Idle" to use 90% of battery, with rest 10% splitted between "Android System" and "can't remember what"
.
But anyway, thanks for the excellent work with these firmwares
p.s. I'm using (and was using with old firmware) min cpu 122 max 748.
p.p.s. Sorry for english. But at least I was able to solve "random registration question" quiz
