If you use them carefully you can easily get 5 years of use, just buy a rugged case & don't charge over 80-90% & avoid discharge under 10-20% for prolonged battery life ~This brings the question who is using a 10 year old device especially cell phone when they're outdated after 4 and battery is crap after 2 maybe 3 at best
I haven't had batteries fail in recent times with some phones over 4+ year old. It does take some doing but you can carefully manage their usage & usability over a good amount of time.
