My personal experience with battery drain 'issue':
I do have a lot of cell standby showing in battery stats like others or maybe more.
However, like one of the previous posters, I don't see any actual drain. To test, I undocked the tablet before I went to sleep (at 99%), and just woke up to see it at 97% 7.5 hours later. Which roughly equals to what it was on 1.8.4 or before with same settings (Setcpu 216 Mhz on screen off). So, basically, I see 60%+ cell standby but I dont actually feel it.
Please note that I'm using airplane mode + Wifi on, and data transfer is turned off under mobile networks.
To anyone reporting battery drain:
1. Please make sure you flashed at 100%
2. Before reporting, full discharge + full charge in off state + wipe battery stats in CWM
As for the smoothness... I don't know what went wrong for anyone who's posting about it, but my experience is that this is by far the smoothest ROM I had on my TF, not een overclocked. Even the browser almost doesn't lag when typing here on XDA (Im on TF right now). OC to 1.4 Ghz makes it fly.
