iPhone14 battery health issues

The measure of battery health deterioration/drainage is subjective and can vary depending on individual usage patterns. There is no universal standard to determine whether the battery health deterioration/drainage is normal or abnormal because it heavily relies on how the battery is used and maintained.

I have visited Apple twice regarding the battery issue with my iPhone 14 Pro after updating to 16.6 these issues started happening. The first time, they suggested that the problem might be with my charger and recommended I buy a 20W block. I followed their advice and purchased the new charger, but it didn't improve the battery life.

Feeling frustrated, I went to a different Apple location a few days later, and they thought it could be a software-related problem. They had me perform a hard reset on my phone and set it up as new, hoping it would resolve the issue. However, even after trying this, the battery continues to drain rapidly. I used to be able to go 10-12 hours without charging my phone. Now I find myself having to charge it fully two times a day. Now I have to remember to bring a charger when I head to campus.

I requested a battery replacement, but Apple refused, claiming that my battery health is still at 100%. Nonetheless, I am convinced that the battery is faulty, especially because I never encountered such problems with any of the 12 iPhones I owned in the past.

I'm unsure of what to do next, as I've exhausted the troubleshooting steps suggested by Apple. I want to find a solution to this battery drain problem as soon as possible. I'm glad that I'm not the only one facing these issues. I don't feel alone.
