I just updated my 1040 Solar to Firmware 20.19 and since then the battery runtime dropped to less than half of what it was before. After only 6 hours of navigating the charge was already down at 10%. Even in non navigating mode, where it just records the route, the battery drains extremely fast. The version 20.19 is obiviousl a major release, since it reseted a lot of my settings. Is there any known issue concerning increased power consumption? As it is now, it sucks! I do a lot of ultracycling stuff and with such a short battery runtime as it is now, it's of no use for me.
