Lumia 830 Standby time

[rodbostock]

The Lumia 830 Specs state a Standby time of 22 days max. Now I know this is under ideal and most likely unrealistic conditions. However I notice my 830 charge will drop by a bit under 1% per hour when not used (WiFi & Bluetooth on) so if it was left just sitting turned on the best I could hope for is about 5 days.
Do other 830 users note something similar? Note that I'm happy with my battery life under normal use, I was just curious as to the theoretical and actual standby times.
On a side note I have noticed by standby drain will double if I'm in a poor cellular reception area.

I suspect it is quoted with Airplane mode on - I.e. all radios off and so pretty much lowest power use.

I know a 635 I have here lasts 12 days with cellular off but Wi-Fi on and no use.

Battery drain in standby highly depends on signal strength and the type of network (2G/3G/4G) you're connected to. 2G should easily last twice as long as 4G, and the better the signal the less amplification aka power will be required.
