What is considered “good” battery life ?

[Turtle69Turtle]

is there a certain standard we all should follow or is it just based off the user ?

My rule of thumb is that if I have about 30% battery when I get off from work and get home, then the battery is good with me.

What is your opinion? I have some screenshots from my first full 24 hours with my iPhone X. I think it’s pretty decent in my opinion. Just got the phone yesterday and I’m really liking it .

Generally speaking, if you are happy with whatever battery life you have, then it is good battery life.
Technically, if a battery can power a certain device a certain amount of time consistently under one usage scenario as per specification, that battery is good. The corresponding time is good battery time.
