I still have yet heard an answer as to the best way to increase longevity in a cell phone battery. Keep it full or draw it down. It appears all hope is lost.
That is unknown to physical science.................
“I still have yet heard an answer as to the best way to increase longevity in a cell phone battery. Keep it full or draw it down. It appears all hope is lost.”
Common facts:
Keep it between 20% and 85%.
Minimize charging cycles.
About the only things you can do is don’t fast charge & don’t discharge below 20%. I think a lot of people will keep their phone plugged into a charger when it’s not necessary, which probably doesn’t help either.
I have kept my cell phone between 20 and 80% since I got it. My battery is much worse than my wife’s, who keeps it closer to 50% all the time.
There’s a setting that lets you limit charging to 80% capacity (max), and it prolongs battery life. I use it on devices that have it.
