I usually disable the data connection, disadvantage is that I'm not able to recieve mms but do get notifications of them and can download them later.
Don't get much of them either so really no big deal for me.
I use ca one-two hour wifi a day, mostly to get new apps to test.
Half an hour I guess is used to play games each day (few minutes here and there).
Ca 1 hour in the phone and around 30-40 sms a day.
A couple of pictures taken the last few days as well.
Alarm turned off, not in standby as I think that "pulls" the phone and drains battery.
And for the moment not in use untill I can manage to lower the volume.
Call Meter NG used to track calls/data traffic, so that's draining battery all the time.
Screen auto-off is sett to 1 minute but I usualle turn the display off when done.
So, I'm no heavy user of my phone, but I get around 3-4 days between charges.
