Battery draining fast on iPhone 15 Pro

Second day with the phone and had to charge it twice today and it’s back down to 19% after normal use…No apps running on background or extended use, battery health at 100% 🤷🏻‍♂️🤦🏻‍♂️

When you first activate it or do an iOS update, the iPhone always tend to drain the battery faster and this is due to the background process iOS does to optimize, including, but not limited to, syncing with iCloud, re-indexing your file system, photos, etc. (for faster search). This is normal and usually ends quickly, depending on the amount of data you have - the more data, the longer it takes.

Same here,In Greece. I have my 15 pro max a week now.It came with ios 17. Since first day the battery was lasting about 7-8 hours with normal use.apple made me do a reset and set as new. AGAIN THE SAME. The way they treat you in Greece is horrible. I gave 1.800€ for this iphone and now they ask me to go to a service to open it amd maybe replace a hardware issue. WHY I HAVE TO KEEP AN OPENED IPHONE AMD REPAIRED while i gave 1.800€? I cant symc with my icloud so they can test it. I m losing money from my work,and they ask me to stay without iphone for several days. Thats unacceptable Apple… Thats really embarasing. 15 years apple owner,first time i want to throw it away. They should check if thats ios problem or hardware.the strange is that 2 friends bought it,and have no issues. Battery lasts for whole day.me on the other,i cant even use gps so i wont stay without battery. Ps.as long as i type this,battery went from 85 to 82%……. During night that i sleep,it will fell 10% more. APPLE DO SOMETHING…!!!

I have been having issues too with my iPhone 15 pro max. I noticed that my battery suddenly went from 48% right down to 38% after turning it off once and turning it back on, then I turned it off and turned it back on and I physically saw the battery percent number drop form 38% to 33%. I looked up videos to fix this issue but nothing seemed to have fixed it.
