That's a fair point, but indeed a lot of people will kill their phone in less than 3 years. Either breaking the screen (which, IIUC, will be also replaceable/self servicable) or killing the battery. Most sources say that the battery will keep an acceptable capacity for around 500 cycles, i.e. 1.5 years if fully charged daily. (Now I don't know, because I'm very cautious not to fully charge and to discharge below 25-3…
> Most sources say that the battery will keep an acceptable capacity for around 500 cycles, i.e. 1.5 years if fully charged daily. This is what I see online, but this hasn't been my experience for any of my devices. My current phone is on year 5 with the same battery, and it's still very decent. I charge it every day to 100% and often plug it back in while it's still at 50%, so it's not like I'm being more careful th…
But if you think about it, it doesn't even work here. First of all, no one can tell you that your battery has a poor capacity, because you test it daily. And people are pretty sensitive to this issue, because we have tricked the manufacturers to create phones that have just enough capacity. (By requiring faster phones, larger, better screens and thinner phones. And not requiring a battery that lasts much more than a day.)
Actually that 'narrative' has the opposite effect: there are a lot of articles online that tell you how to enhance the life of the batteries. (Whether it's really needed or not doesn't make a difference.)
Regarding charging it from 50%: this is not something that hurts Li batteries. Actually it's better than allowing it to drain (or go into some unspecified low percentages, probably below 20 or 10). Charging to 100% is said to have a negative effect. I mean it probably wears faster than if you charge to just 85%.
