- A growing number of Galaxy S25 Ultra and Galaxy S24 Ultra users are reporting significantly worse battery life, overheating, and even slower charging after installing the software.
- One owner said their handset previously delivered normal battery life before the update. After installing the July patch, however, they claimed the battery dropped from around 85% at midnight to just 5% by midday despite logging only around two hours of screen-on time.
- The same user also reported unusually high idle battery drain, claiming the phone now loses between 5% and 7% of its charge every hour, even when it’s not actively being used.
- In a separate Samsung Community thread, one user said their phone had comfortably lasted a full day on a single charge before the update. However, battery life has noticeably deteriorated since installing the latest software.
- Several users replying to the discussion threads claim their devices are also running much hotter than before, even during relatively light use.
- Others have reported slower charging speeds. This suggests the update may be affecting power management more broadly.
Galaxy S25 Ultra and S24 Ultra users are facing significant issues following the July security update, with many reporting battery drain, overheating, and slower charging. Users have noted that their devices are losing between 5% and 7% of battery life every hour, even when not in use.1
One user shared their experience, stating, "the battery dropped from around 85% at midnight to just 5% by midday despite logging only around two hours of screen-on time." This alarming trend has led to widespread concern among users, as many report that their devices are running much hotter than before, even during light usage.25
Despite the growing number of complaints, it remains unclear how widespread the issue is. Samsung has yet to publicly acknowledge these reports or confirm whether the July security patch is the cause of the problems. As users continue to voice their frustrations, the tech community is left wondering about the implications for future updates and device performance.
The situation highlights the potential risks associated with software updates, particularly for flagship devices that are expected to perform optimally.
