I just used once a year as an example. I’ve noticed after 1 year I no longer get 2 day battery life on my Xperia whereas for the first year I only charged it every second day. Now I charge every night.
If I had a Samsung I’d just go have it swapped out in 1 hour and be back to 2 day battery life.
If you ask most average people why they are getting a new phone it’s normally because the battery no longer lasts all day and they have to change up mid day. If they had a way to easily and quickly, and cheaply, have the battery replaced with waterproofing still in tact, many would do that and not have to get a whole new phone.
I can’t imagine using the battery for 5 years. After 2 years my V30 only gave me 2-3 hours of screen on time max. I AVOIDED using it just so I could make it through a work day in case I got a call. And no 3rd party repairer had Lg batteries…
A mobile phone without a dependable battery is a paperweight. What’s the point of having it if it always has to be plugged in to a charger???
