I'd like to offer my feedback about the battery thing.
After applying the OTA update (which we all know doesn't fix the reboot and battery drain issue) I have performed a factory reset.
Following that I had ZERO reboots.
Issues of note:
- Following the factory reset I was able to uninstall google+
- A new option appeared to disable services which cannot be uninstalled, like Asus My Zine.
So it might be that, and not the factory reset itself.
Regarding the battery:
- I have unplugged the Transformer exactly 5 hours ago. 100% battery charge, brought it to work, but didn't use it at all. Wifi was on though. In 5 hours i got 9% battery drain, which is absurd, especially comparing it with Honeycomb.
I have applied the fix specified in this thread, and I'll monitor the situation, and report back.
Thing is, if the reboot "fix" is permanent, that will save me some battery life, as having the tablet reboot itself and being stuck in a bootloop for a while ate a lot of battery. Regardless of that, ICS is a big disappointment in terms of battery life
My Transformer is a B50 unit, not rooted.
