Doesn’t sound too bad?
- xattt 2y agoPeople typically own vehicles for more than one year.
- sroussey 2y agoIf after one year, it should have 29 years of life left but instead will last 26 then it sounds like the chips won’t last 8 years (instead of 30). Sounds bad to me.
- jajko 2y agoCan you please continue stated math for each year? You reach 0 faster than expected
- loaph 2y agoI think it does sounds really bad. After one year, 26 years lifespan. We get that by doing: 30 - (30.1 - 1) = 26. Doing that again for the next year: 26 - (26.1 - 1) = 22.4. So you now have 22.4 years of life vs an expected 28. etc...
- Kirby64 2y agoIf the math is correct, you'd have an expected life of ~10.2 years. (30*(0.9)^n - n) = 0. That said, when someone says "it reduces the lifespan by 10%", I'm a bit skeptical of the math. Either they are not properly testing it, or the temperatures are exceeding silicon parameters.
- adamc 2y agoDo the math. It's bad.
