If your Samsung Galaxy A14 battery is draining fast after a recent update, you’re not alone. Many users notice sudden battery drop, overheating, or faster percentage loss after installing a new Android update.
The good news? In most cases, this is a software issue — and it can be fixed.
This guide walks you through 9 proven solutions that work on Samsung Galaxy A14 running Android 13 or Android 14.
Why Battery Drains After a Samsung Update
After a system update, your phone:
Re-indexes apps and files in the background
Re-optimizes system processes
Resets some battery usage behavior
May cause app compatibility conflicts
This temporary system activity can increase battery usage. But if it continues for days, something else is causing it.
Let’s fix it step by step.
Fix 1 – Restart Your Samsung Galaxy A14 Properly
After an update, a simple restart often fixes abnormal background processes.
Steps:
Press and hold Power + Volume Down
Tap Restart
Wait 2–3 minutes before opening apps
This refreshes system services and clears minor glitches.
Fix 2 – Check Battery Usage for Problem Apps
Sometimes one app is responsible for heavy drain.
Steps:
Open Settings
Tap Battery and Device Care
Tap Battery
Review which app is using the most power
If one app shows unusually high usage:
Force stop it
Update it
Or restrict background usage
Fix 3 – Update All Apps from Google Play Store
After a system update, some apps may not be fully compatible.
Open the Google Play Store and update everything.
Steps:
Open Play Store
Tap your profile icon
Tap Manage apps & device
Tap Update all
Outdated apps are one of the biggest causes of post-update battery drain.
Fix 4 – Clear Cache Partition (Safe & Recommended)
System cache conflicts are common after updates.
This does NOT delete your data.
Steps:
Turn off your phone
Press and hold Power + Volume Up
Release when Samsung logo appears
Select Wipe cache partition
Confirm
Reboot device
This removes corrupted temporary system files.
Fix 5 – Restrict Background Usage for Heavy Apps
Some apps continue running aggressively in the background.
Steps:
Go to Settings
Tap Apps
Select heavy battery app
Tap Battery
Choose Restrict background usage
This immediately reduces drain.
Fix 6 – Disable Always-On Display
If Always-On Display is active, it constantly uses power.
Steps:
Open Settings
Tap Lock screen
Tap Always On Display
Turn it off
This alone can improve battery life noticeably.
Fix 7 – Reduce Screen Brightness & Refresh Rate
Screen usage is the biggest battery consumer.
Do this:
Enable Adaptive brightness
Reduce brightness manually
Lower screen timeout to 30 seconds
Small adjustments can add hours of battery life.
Fix 8 – Check for Another Software Patch
Sometimes Samsung releases a quick follow-up fix.
Steps:
Go to Settings
Tap Software update
Tap Download and install
If an additional patch is available, install it.
Fix 9 – Factory Reset (Last Resort)
If battery drain continues for more than 5–7 days even after all fixes:
You may need a reset.
⚠️ Backup your data first.
Steps:
Settings
General management
Reset
Factory data reset
This clears deep software conflicts.
