The latest April 2024 Security Patch from Samsung, intended to bolster security and stability, has reportedly backfired for many flagship users. Owners of the Samsung Galaxy S24 and the newly released S25 series have taken to forums like Reddit and Samsung Community to report significant battery drain and minor overheating issues following the update.
If you’ve noticed your premium device struggling to last through the day, you aren't alone. Here is everything you need to know about the situation and how to mitigate it.
The Problem: Rapid Power Loss & Overheating
Post-update, users are reporting a noticeable drop in Screen-on-Time (SoT). Devices that previously lasted an entire day are now hitting the 20% mark by late afternoon. In India, where ambient temperatures are rising, some users also reported that the Galaxy S24 and S25 series are running warmer than usual during basic tasks like scrolling social media or light browsing.
Affected Devices:
Samsung Galaxy S24, S24+, and S24 Ultra
Samsung Galaxy S25 and S25 Ultra
Why Does This Happen?
Software updates often trigger intensive background processes like file re-indexing or app optimization. However, when the battery drain persists for more than 48 hours, it usually points to a "rogue process" or a bug in the firmware's power management script that fails to put background apps to sleep.
How to Fix Battery Drain on Your Galaxy S24/S25
While waiting for a hotfix from Samsung, try these expert-recommended steps to stabilize your battery life:
Wipe Cache Partition: This is the most effective fix. Turn off your phone, connect it to a PC via USB, and hold the Volume Up + Power buttons to enter Recovery Mode. Select 'Wipe Cache Partition' (this won't delete your data) and reboot.
Update All Apps: Sometimes the system update creates a conflict with older app versions. Ensure all apps in the Google Play Store and Galaxy Store are updated.
Check Background Usage: Go to Settings > Battery > Background Usage Limits and ensure unused apps are set to 'Deep Sleep.'
Reset Mobile Network Settings: Occasionally, updates cause the modem to "hunt" for a signal more aggressively. Resetting network settings can help recalibrate the 5G/4G connectivity.
Disable Always On Display (AOD): As a temporary measure, turning off AOD or setting it to "Tap to Show" can save 5–8% of battery life daily.
Final Thoughts
Samsung is known for its rapid software support, and it is highly likely that a secondary "optimization patch" will be released shortly to address these power consumption bugs. Until then, the steps above should help you regain some of your device's endurance.
