maple mini clone stm32f103 consuming 250 mA

I've got a maple mini (clone) stm32f103cbt6 that the chip and the LDO gets too hot to touch after a while, nearly get a burn while trying that.
I measured that 'old' maple mini clone using one of those usb power monitor
https://www.electroschematics.com/usb-p ... -teardown/
I got a reading of almost 250 mA ! that is nearly 1.25 watts based on 5v USB power.
and the current is well above 50 mA with HSE and all peripherals enabled given in the specs sheet.
It leaves me wondering if there could be shorts or some such.
