You managed to create lithium batteries lasting for 100 years (meaning an iPhone user can scroll for a long time until the individual dies of old age without stressing if the phone will run out of battery). To put it into perspective: Nuclear Submarines can go on without refuelling for at least 50 years, so if you double that lifespan on a lithium battery: how would it shape modern electronics? What would it be like having a battery that can last an entire century?
That would mean iPhone & Android users don’t have to recharge every 10 hours or so (becomes every 876000 hours) meaning let’s say you bought an iPhone whilst in school it’s a full bar, by the time you are at old age living your golden years (it hits 5%) and throughout your entire life you forgotten that phones need to be recharged due to having a device that can last basically forever due to the battery being that powerful & having a long lifespan.


Given the pace of technological progress, I doubt a phone bought today will be all that useful (except as a retro novelty) in 20 years time, let alone 100.
How many people do you think are still daily-driving a Motorola KRZR? It’s not because of the battery life.
I don’t know if you knew this or not, but the KRZRs actually WERE known for having terrible batteries. Every time somebody brought one in with battery issues, we’d pop the battery out, set it down and give it a spin. More times than not, a cell had burst inside and that battery would be swollen to hell.
I thought it was funny that you just happened to pick a phone that people actually DID get rid of just because of the battery!
I did not! I actually had one back in the day and never had battery issues, but pretty funny to hear it was a common complaint.
(Still, I think the broader point stands.)
The point absolutely stands, despite the irony.
I have a friend who had an iPhone 3 until 3g got shut down 18 months ago. You don’t need to buy into the constant update cycle.
That also kind of proves OP’s point though. 3G was shut down, making an iPhone 3 pretty much useless at this point. You can use these things a lot longer than they want or expect you to, sure, but 20 years is a stretch, and 100 years is untenable.
