I've did some more "measurements" with my Q10 - i.e. systematicaly recorded the times of usage. Here they are:
# 2G + 3G, Wifi off, unlock only via Power Key
# Do 4.7. 12:20 fully charged - Sa 6.7. 10:00 yellow blinking, empty
# Sa 6.7. 12:30 fully charged - So 7.7. 22:00 turns off (lots of pictures taken)
# Mo 7.7. 09:00 fully charged - Mi 10.7. 11:30 turns off
# 2G only, Wifi off, unlock only via Power Key
# Do 11.7. 08:30 fully charged - Di 16.7. ~10:00 turns off
# Di 16.7. 17:00 fully charged - Sa 20.7. ~18:00 turns off (incl several downloads through Wifi)
# 3G [three!] only, Wifi off, unlock only via Power Key
# So 21.7. 09:00 fully charged - Di 23.7. ~21:00 yellow blinking, 0% battery
# Mi 24.7. 09:00 fully charged - Fr 26.7. ~15:00 yellow blinking, 0% battery
As I wrote before, I'm more of a classical user than a geek. I'm using the phone to make and receive a couple of usually short calls per day, check my mail maybe 3-4 times per day, have a look at my calendar maybe 1-2 times per day. Overall active usage of the Q10 is most likely somewhere between 45-60 minutes per day most of which are phone calls.
To sum up the results
Hope this information may be useful to someone who is sufferung from unacceptable standby time.
BB should probably invest some brain power into their network selection / polling algorithm. When on 2G the phone is reachable and as long as you are static it can even retrieve small amounts of data (like email headers or calendar updates) with reasonable delay. When the user launches a browser or attachments need to be fetched the phone could switch to 3G or 4G. Can't be that hard to implement given that BB has complete control of the sources unlike most Android "producers".
