Literally all Certaphone low battery videos i've seen are really low effort. This video actually has some effort put into it. The battery percentage isn't big as heck and the interface looks acceptable. The only flaw is the startup sound (unless you're able to pick whatever startup sound you want, I'm pretty baffled by it). This is by far the most detailed Certaphone low battery/shutdown video I've come across. I'll make a shortened one for the little kids who don't understand English too well; this is the best low battery video I've seen.
