iPhone 15 pro battery health at 93 percent after less than 7 months

i first used my iPhone 15 pro in November 2023 and the battery has been drastically dropping since late March. at the start of this month, my battery health was still at 96% but dropped to 95. soon enough three days ago it dropped to 94%, now today it’s gone down to 93%. i’m starting to think that there’s a problem with my 15 pro’s battery. my phone is at 305 cycles with less than 7 months of usage. i have to charge my phone at least 3 times a day even when i constantly have low power mode on. i can’t even get the full experience of high refresh rate with low power mode constantly being on. im very disappointed as i expected this phone to last me 3-5 years but at the rate my battery is dropping it won’t even last 2 years before going below 80%.
