What's a reasonable battery discharge rate for an iPhone 6
that's powered on but in airplane mode with WiFi off?
 I expected one or two percent per day, but it seems quite
a bit faster. After two or three weeks it's ~50% and falls
a percent every couple of minutes when used actively.
 The battery is about six months old, replaced by a local shop.
Maybe I got a dud? Is there a simple test?

My question is why carry a cell phone with its power on in this condition? The only connection left is Bluetooth.
First turn off Bluetooth besides Airplane Mode.
Second go to Settings > General > Background App Refresh and shut off what you do not want running when ever the iPhone is powered on but off.
Then recheck battery usage over time before the drastic step of low power at all times.
