Everyday battery drain

This has started recently, and I'm pretty sure it wasn't the case before - though I can't put my finger on when it exactly started.
The battery now drains pretty fast when I'm not doing any activities.

Yesterday I charged the unit to 100% and disconnected it at 14pm The time is now 7am and the battery gauge shows 86%.
14% in 17 hours means 121 hours of battery life with no activities - 5 days.

I have 24hr HR turned on and tracking steps/floors climbed.
Is anyone else experiencing this?

I'm down to 90% after 27hrs. No activity, no BT and no music. Just turned on the backlight here and there and wrist heart rate was on. I think this is better than it was before with FW 3.70.

skopek BT off means your 645 is not connected to your phone?

Yes, it's not connected.

Yes, it's not connected.

That might explain why you're draining 10% for 27 hours when mine drains roughly 1% per hour (with BT). I'm just sure this wasn't the case up to recently.
