It started out well - when I took the watch off charging in the morning I activated the phone, WiFi, bluetooth and paired my bt headset, and turned off cell data. I played around with the phone a bit (installed an app, played with that for a few minutes, checked settings and tried some new things there for maybe 10 minutes or so, and so on). I recieved two calls that lasted about 5 minutes each, and checked mails, facebook and such a few times. After lunch the battery showed 78% remaining, which sounded very good.
I decided to take a walk, so I turned off WiFi, enabled cellular data, and turned on GPS. Listened to podcasts through BT headset for the entire walk. One hour walk with RunKeeper, where I checked mail and facebook a few times during the walk.
After returning, the battery was down a lot, to about 25%, ie 50% battery drained in one hour. I checked the battery stats, and it looked like this: (not a link as I can't post links yet due to forum restrictions): imgur.com/WPQJNd4
I'm not surprised about WiFi and BT consumption as I had those enabled and used them quite a lot during the day, but what surprised me is the cell standby adding up to almost 50% of the battery usage, most of which seemed to be drained when I enabled cell data. Is GPS drain included in cell standby as well? Is this to be expected, or what's causing the excessive drain when using cell data connection? Any tips on how to improve this?
My cell coverage during the walk was decent, as I was outdoors and had at least 3-4 bars of reception the entire time.
