So i was actually researching about the proper way of charging my iPhone. And most of the people from forums are saying that they'll start charging their phones at 30-40% point until it reaches 80 and then unplug it. I'm not sure if it's the right way but I'm planning to do the same. I just want to ask if anyone could explain why they do that and will it be okay if I do that too? Should I stop at 80% or it'll be fine if I top it up up to 100%? I'm really confused. I just dont want to brick my battery again. P.S. I JUST HAD MY IPHONE 5 battery replaced sinced I murdered it too soon because apparently my charging habit is wrong by draining it to zero and then fully recharging it again.
