Hi,
I jumped a few days ago on a bright day and I noticed that it was hard to read my altitude. In the system info I saw the screen brightness was at 70%, with no way to increase or decrease it. In 2018 someone posted about this same issue. If the altimeter’s battery life drops too quickly when its brightness is at 100%, I don’t think the solution is to force the brightness down. I would way rather have a bright, readable screen during my jumps than to have a dim screen that allows me to go an extra hour without needing to charge. Maybe set the brightness to 100% when in freefall mode, but program it to go to 70% on the ground. Or give us the control and let us suffer if the battery dies quickly.
