Moving this issue from lupyuen/pinetime-rust-mynewt#36

Lup doesn't work on mcuboot anymore and his repo isn't the right place for this issue.

@vbelloir says:

I'm working with @JF002 on power consumption of Pinetime watch, using Infinitime from JF.

I noticed that consumption is higher when Infinitime is booted by mcuboot than when it is stand-alone. Difference is about 500µA.

As a example, I disabled watchdog in bootloader, and add a simple __WFE loop in main function of Infinitime.
Booting from mcuboot gives a consumption of 574µA, while booting in stand-alone configuration gives 170µA.

Resources may be used in mcuboot/mynewt and not de-initialized in mcuboot, nor in Infinitime.

Do you have any idea for me? How can I identify which resource is consuming power?

Thanks for your help.
Vincent

I'm investigating this and will report any findings.
