iPhone 14 pro severe battery drain issue (10 days after purchase).
Battery draining very fast on 10 days old iPhone 14 pro with 100 percent battery health, even faster than my iPhone 11 with 76 percent battery health. On a cellular call of 15 mins, the battery is draining 9-10 percent. All of my settings are on minimum battery usage. No widgets, always on display off, location off, background app refresh off, auto brightness on, only WhatsApp notifications are on (rest all are off). I called Apple support, and they ran diagnostics on my phone and the results were fine. Battery health is 100%. I have charged my phone only thrice since the time I bought it as my usage was bare minimum in 10 days (2 Hours average screen on time). Still, after all this, my battery is draining significantly just by basic cellular phone calls and 10-15mins scrolling through social media. Apple support asked me to visit the Apple service center. They've asked me to restore my phone through Mac and check it, I have already restored my phone and still facing the same issue. Kindly suggest what should I do next.
