+_Update 2023-03-14:_ The new battery has arrived. I installed it (alongside
+a quick clean-out of the fans and heatsink) and did a full charge, followed by
+a discharge to 0%, followed by a charge back up to full in order to calibrate
+it. As far as power draw, it looks like OpenBSD draws roughly 8-9W at idle and
+Linux can go as low as 1.5-2W. Battery life is roughly 5-6 hours on OpenBSD and
+estimated at 9-12 hours on Linux, depending on the workload and screen
+brightness. This makes sense given that OpenBSD does not implement a lot of the
+powersave functionality in most (if not all) of its drivers.
