I bought my iPhone 12 in March 2021. I use both 5g and wifi for over 2 months. After I updated to IOS 14.5, I noticed that my battery health went from 100% to 95% in just 2-3 months. After that, I stopped using 5g and just used wifi. But it is still draining fast. I only use my phone for social media and use it for gaming sometimes. I also use Apple’s 20watt charger. I also don’t let my battery life go down to 25%. Now, my battery health is at 92% in just 5 months of using it. What exactly is the problem and how can I prevent my battery health from draining too fast? Is my battery defective?
