3. ENABLE Cellular data (3G) all day > Battery will be empty at ~16h

1. System Settings
2. Cellular

Hi!
I was testing the battery drain with the all available options and I think it's not right. I used the same brightness and there weren't new messages, then the mobile use in all modes was the same.

Please, take a look at the attachment screenshot.
My behavior was:
Charge the battery all the night
 8:00 Unplug the adapter.
 8:00 - 11:00 Airplane mode
11:00 - 13:30 Only calls (Disabled Cellular data)
13:30 - 16:00 Calls & 3G (Enabled cellular data)
16:00 - 18:30 Calls & WIFI

As you can see, the battery drain was really similar, but in airplane mode has to be less drain that in by example 3G, with calls less drain that with 3G, etc.

Thanks in advance!

summary: - Ubuntu Phone: Same battery drain with 3G and without 3G
+ Ubuntu Phone BQ: Same battery drain with Airplane mode, 3G, no 3G and
+ WIFI
