Samsung's July 2026 security patch is designed to deliver fixes for its phones, but if you’re experiencing reduced battery life, overheating, or slower charging speeds, you’re not alone. The brand has yet to acknowledge any issues, but complaints from Galaxy S25 Ultra and Galaxy S24 Ultra owners are piling up on Samsung’s forums and Reddit. One Samsung community forum user says they’re getting just 2 hours and 10 minutes of battery life on their S25 Ultra since installing the update. This means the vast majority of my battery drop (roughly 60%+) is happening purely when the phone should be in deep sleep.” We asked Samsung for comment and will update this story if we hear back.
