I've had a Galaxy S23 Ultra for about a year and a half. Everything is okay, and I'm satisfied, especially with the great camera, which allows me to take nice, high-quality photos. There is one problem, however: the terrible battery. Unfortunately, for the past few months, the battery has been draining quickly, and its health has deteriorated. A full charge now lasts less than 10 hours, even though it lasted over a day just a few months ago. I've tried to protect it by turning on various power-saving functions, but not only did this not help, the battery life is getting worse.
What should I do to protect my battery? Is a battery replacement necessary in this condition?
