I believe optimum charging for battery lifespan is charging to around 80% and only discharging down to 20%. What you’re doing is basically the worst thing possible.
But a phone is a device. It works for you, not the other way around. Replacing a phone battery isn’t terribly hard or expensive.
Not really. Worst thing is running the cell dead or cooking it. Modern lithium cells are much less prone to damage at full capacity (because it’s not really full, your phone’s charge controller is using intelligent management for 4-5% of it) and it doesn’t really matter how often you cycle charging on/off either with modern anode configurations. You’re correct on the usage part though. Tools wear out. Just how it goes.
I literally kept my last phone from September 2019 to October 2025.
I also never heard that fast charging reduces battery life, I constantly discharge and connect the charger probably 30 to 40 times a day.
I sure wish that this knowledge was universal.
