Samsung Phone Battery Issues Surface Post-Update
29 Jul
Summary
- Samsung Ultra phone owners report severe battery drain post-update.
- Devices also overheat and charge slower than usual.
- Users cite issues particularly with WhatsApp after the update.
Owners of the Samsung Galaxy S24 Ultra and S25 Ultra have reported alarming battery issues following a security update released in July. Users on platforms like Reddit and Samsung's forums have detailed substantial battery drain, with one user noting a drop from 85 percent to 5 percent within two hours of screen time.
Beyond rapid battery depletion, some users have observed their devices running significantly hotter than normal and experiencing slower charging speeds. These issues appear to have surfaced after the recent July security patch, leading to user frustration and speculation about the update's impact.
As of late July 2026, Samsung has not officially commented on the widespread complaints. Concerns are mounting that this July update may be the root cause of these multiple, simultaneous problems affecting the high-end Ultra models.
