Is it just me or does 3.2 eat batteries for breakfast, lunch and dinner?

My usual pattern for the past few days. All of that without actually using the phone (J1), just background tasks such as the phone checking for emails every 30 minutes. No new apps, just a system upgrade (and patches when available):

• Evening, around 22:00. Take the phone off the charger. Battery level 100% or very close (sometimes I take it off to plug in something else before I reach full 100%).
• Morning, 05:30 to 07:30, depending on the day. Battery level around 75%. Put it on a charger again while I do my morning routine.
• Mid afternoon. Battery level around 40%. Sometimes as low as 9%.

In addition, any period of no radio signal speeds up the battery drain by a factor of at least 3. I frequently move into an area where both WiFi and mobile network disappear for a while which makes it easy to notice the difference.

EDIT:
I wake up more than an hour before anyone else in my house and use the phone as an alarm clock. I used to keep it under the pillow so as not to wake up my nearest and dearest, but after an upgrade to 3.2 I very quickly learned not to do that because the phone was very hot and the battery below 50%, despite being full before I went to sleep.
