The HTC 10's battery condition seems to be fairly well-accepted now; some people have no issues whatsoever, the rest have a phone that calls it quits at 50%, goes into bootloops (because it dies. because it pumps the screen at full brightness and fires up every component and - if you're lucky - plays back a provider video. genius.), and overall just gets worse and worse.
Mine starter with the 40-50% death. Then it was a matter of half an hour, and it'd die, sometimes displaying a battery with a red circled exclamation mark indicating - I presume, since there's no manual to speak of - the battery being crap (which is great, given how easy it is to replace /s). Eventually just a few minutes with screen on would mean it'd turn off.
And then there's the past week. Unplugging is an exercise in turning it off real quick, and if I got real unlucky, plugging it in would just make it instantly die again as the screen would turn on and the charging circuitry takes a moment to switch to fast charging... culminating into tonight: it's plugged in, 'charging rapidly' (who knows if QC3 played its part in all this), but in reality the battery level is slowly but surely dropping. Not that that level can be trusted all that much, but I presume it can at least still take relative readings.
I'm well past 2 years on it, so in modern society I'm overdue for replacing it, but I really rather enjoyed this phone while it was still doing well, and it's a shame that the only reason I might have to sell it for parts - or just trash it entirely - is because the battery is behind a dozen layers with fragile screens and connectors.
The last post here that mentions actually having it replaced by a service center is from April. Is 'cellphonerepair (dot) com' still a good bet? I know I can request a quote, just seeing if there's other alternatives people have successfully used recently, seeing as I'd much rather have it around either as a daily driver while looking for a replacement, or at least as a better stand-by than my current stand-by.
