Question: Battery health
I got my phone for 3 months already. But its battery health is already at 93%. What should I do?
If your battery's Maximum Capacity shows a value of 80% or less than it has gone through its lifecycle and therefore should be replaced, according to Apple. A battery, under normal circumstances, will last performing well for about 2+ years.
Your battery health is at 93% on an iPhone that was probably first placed for retail sale 20 months ago. Did you buy your iPhone secondhand? The reason I ask is because it may have been 3 months with you however in reality it is 20 months old.
Your battery health is fine and is undergoing normal usage. Here is some more reading on an iPhone battery and its performance-->>iPhone Battery and Performance - Apple Support
