Samsung Galaxy users report battery drain and overheating issues after July 2026 update; complaints pile up on forums

Samsung Galaxy users are increasingly voicing concerns over battery drain and overheating issues linked to the July 2026 security update. Reports indicate that devices such as the Galaxy S24 Ultra and S25 Ultra are experiencing significant battery loss, with some users noting a drop from 85 percent to 5 percent within hours of minimal use.²⁴⁷⁹

One user reported, "The device is draining roughly 5% to 7% of battery per hour while sitting completely idle on a flat surface." This alarming trend has led to complaints of battery levels decreasing by 5 to 7 percent per hour even when the phones are not in active use. Additionally, many users have observed their devices running hotter than usual, with some stating that charging speeds have also diminished.⁸

Despite the growing number of complaints on forums and Reddit, Samsung has yet to publicly acknowledge the issue or provide a timeline for a fix. Historically, fixes for such problems have been addressed in subsequent updates, leading users to speculate that a resolution may come with the August update.

While some users have attempted to find temporary fixes, the effectiveness of these solutions remains uncertain. One Reddit user attributed their battery drain to WhatsApp, suggesting that specific applications may exacerbate the issue. As complaints continue to mount, Samsung faces increasing pressure to address these critical performance problems.¹⁰¹¹
