Samsung July update Causing Battery drain issues
A growing number of Galaxy users have reported problems after installing Samsung’s latest July security update. The issue appears to affect mostly the Galaxy S25 Ultra and Galaxy S24 Ultra, although some owners of other Galaxy devices have also shared similar experiences.
The most common complaints related to Samsung July Patch include:
- Battery draining much faster than usual
- Phone becoming hot during normal use
- Higher battery usage while the phone is idle
- Slower charging for some users
- Occasional lag or temporary freezing
Many users say Samsung July update overheating problems have been the most problematic update for them in years.
Galaxy S25 Ultra and S24 Ultra owners report overheating
Several Galaxy S25 Ultra and S24 Ultra owners say their phones now become warm even during light tasks like browsing or messaging. Some users also noticed their battery dropping much faster throughout the day.
A few users reported that the phone remained hot while sitting idle, suggesting a background process could be using more CPU than expected. Others even experienced short freezes after the update.
At this point, these are community reports, and Samsung has not acknowledged Samsung July update overheating issues, yet.
WhatsApp backup may be causing the issue
One pattern appears repeatedly in user reports of Samsung July Patch is WhatsApp.
Many affected users discovered that WhatsApp’s encrypted backup process gets stuck on “Preparing backup.” While this happens, the app continues running in the background, causing excessive battery drain and making the phone heat up.
Some users said that after stopping the backup, their phones immediately cooled down and battery life returned to normal. This might indicate the Samsung July update causing Battery drain correlates to WhatsApp.
Several users believe the July update may have introduced a compatibility problem with WhatsApp’s encrypted backups. However, this has not been confirmed by Samsung or WhatsApp.
Not every Samsung user is affected
Interestingly, the issue does not appear to affect everyone.
Some Galaxy S25 Ultra owners said their phones continue to work normally after the July update, with no signs of overheating or battery drain.
What users have tried to fix the problem
While there is no official fix yet, several users have shared temporary workarounds only for the Samsung July update causing the battery drain problem.
These include:
- Stopping or canceling the stuck WhatsApp backup
- Clearing the WhatsApp cache
- Temporarily disabling end-to-end encrypted backups
- Performing a successful backup without encryption and then enabling encryption again
- Restarting the phone
- Factory resetting the device (reported by a few users)
- Waiting for a newer WhatsApp version, as one user reported the issue was fixed in WhatsApp version 2.26.30.2
Final thoughts
The July Samsung update has generated a large number of community reports about battery drain and overheating, especially among Galaxy S25 Ultra and Galaxy S24 Ultra owners. While many users point to WhatsApp’s encrypted backup as the likely trigger, others continue to experience the issue without WhatsApp, meaning the root cause is still unclear.
