I think it does. I've been interrupted more than once mid-flow while programming to recharge the battery. Or say, you're in the middle of a presentation. There are lots of mission-critical uses, which can't easily tolerate an interruption. You can't stop to recharge, and it's silly to compulsively check the battery, or carry multiple mice to avoid that situation. When the system was new, there was a reasonable warning ahead of time on the battery level, but now the warning is not sufficient for a work around, and the mouse much be charged within a minute or two.
