Last week i updated my Samsung S25 Ultra to the latest software version, and since then, I’ve noticed significant battery drainage. The battery is depleting much faster than usual, even with minimal usage.
Please advise on how this can be resolved or if there is a fix planned in an upcoming update.
You're not alone—many users have reported faster battery drain after updating to Samsung One UI 7 (based on Android 14). This can happen due to background processes, optimization delays, or app compatibility issues. Here's how to fix or reduce battery drain:
Quick Fixes:
Restart your phone Sounds basic, but a restart often helps background processes settle post-update.
Clear cache partition This can fix issues without deleting personal data.
Power off your phone. Hold Power + Volume Up until the Samsung logo appears. Use volume buttons to navigate to "Wipe cache partition", and confirm with Power. Reboot when done.
Check battery usage
Go to Settings > Battery > Usage since last full charge. Identify any app that's unusually high. Force stop or uninstall/update it. Settings Tweaks:
Enable Adaptive Battery & Power Saving
Settings > Battery > More battery settings > Adaptive Battery Turn on Power Saving Mode if needed (customize it to still allow notifications).
Turn off Always-On Display, 5G, or high refresh rate if not needed:
Update all apps App incompatibility after an OS update often causes wakelocks (background battery drain).
Open Galaxy Store and Play Store, update all.
Battery Calibration (optional) Let the phone drain completely to 0%, charge to 100% in one go, then restart. Do this once after a major update to reset battery stats.
Wait a few days Post-update, Android reindexes files and learns battery usage, which may drain power for 1–3 days before settling.
If it still drains heavily after a week, consider a factory reset (after backup), or contact Samsung Members app support for diagnostics—they might patch it soon.
