NANOPI R1

The NanoPI R1 RTC have a huge comsumption of power.
On day 22 I put a panasonic cr2032 battery in the RTC, with 3,229 volts.
On day 25 the battery had 2,915 volts.
I measured the consumption current: 155uA

Is there anything I can do on the board to solve this, or something that friendlyelec can do on a new version of this board?
Or some hack to solve this problem?

At 155uA you should be able to get at least 50+ days out of the 240mA rated CR2032. In saying that, the standby current is still too high for an RTC in standby.

What ambient temperature is the device operating in?

PS. I used this calculator.
