Airplane mode seems to make very little difference to the standbyish time of my Android phone. Recently, I've left it non-airplaned whilst running GPS, and as long as data's off, everything's fine. Today, for example, saw just shy of 5h30 of tracking, with just over 5h of that moving. I took it off the charger when I got up at 6am, left the house at 7am, and when I got home at 12.30, the battery was still half full. I've run it for 7h before, and still had a third of the battery left. I realize this will deteriorate with an ageing battery, but I'm sure it'd just about manage 8h of tracking. It's an HTC Incredible S, BTW.
Saying all that, I'm thinking about a Garmin Edge 200 to replace assorted bike computers with probably-not-much battery left. Partly to retain the phone's battery just for comms use, plus occasional Gmap checking; plus maybe music playing. Partly for slightly improved GPS accuracy. The HTC is good, but I've missed a few 'critical' bits under tree cover in the past.
But it will be another thing to remember to habitually recharge. Oh, the stress.
