I bought the Samsung S24 Ultra approximately 8 months after its release and used it happily and without any issues for about 1.5 years. In September 2025, I also purchased the Galaxy Watch 8 as soon as it was released and started using it in sync with my phone.
For a long time, I was extremely satisfied with the battery performance. However, the sudden battery drain I experienced in recent weeks pushed me into a serious research process.
Why Am I Writing This Article?
As a Samsung S24 Ultra user, I’m writing this not as a review site, but as an actual user.
Because this problem:
- I didn’t just read on a forum and move on
- I didn’t notice in one day and magically fix
- I didn’t guess by saying “I think”
I personally experienced it, tested it, and solved it. I hope it will guide you as well.
I’m a user who spends the day on social media, listening to music, checking notifications, occasionally watching movies, and very rarely playing games. My battery easily lasted 17–18 hours (sometimes even longer). I am absolutely not exaggerating. There were even days when I could finish the day and still plug it in the next day.
But suddenly, I started charging my phone 2–3 times a day. The battery drain I experienced in recent weeks seriously frustrated me, and I said to myself: “Alright, it’s time to roll up my sleeves and research.”
The Battery Started Acting Like It Was “Melting”
I’m really not exaggerating:
- 100% → 30% in 4 hours
- Not touching the phone → 10–20% drop in 10 minutes
- Screen off, in my pocket → battery keeps draining
That’s when I thought:
“There’s no freezing or overheating. This phone simply cannot behave like this. Something is wrong.”
First Suspect: Battery Health? No.
The phone is:
- 1.5 years old
- No overheating
- My charging habits are regular
At this point, I considered whether battery health had dropped, but the device simply wasn’t old enough for that. So I focused entirely on the software side. In other words, the possibility of hardware battery degradation was extremely weak.
While I wasn’t 100% certain, I immediately shifted my focus to software.
I was going to find the problem.
(And I did.)
THE TURKISH VERSION OF THE TEXT –> Samsung S24 Ultra Pil Sorunu ve Çözümü
Research Process: Trial & Error and Forums
What Did I Do?
- Foreign forums
- Turkish Samsung & Android forums
- Checked system settings one by one
- Uninstalled unused applications
- Tried deep sleep / sleep modes
- Consulted Samsung users around me
Result?
None of these provided a permanent solution. I couldn’t find a clear, definitive fix.
Samsung Good Lock Battery Issue: The Real Culprit
During my research, I came across numerous battery drain complaints related to Good Lock, Samsung’s official application, on foreign forums.
What Is Good Lock?
An official Samsung app downloaded from the Samsung Store that includes modules such as:
- Interface customization
- Lock screen
- Task manager
- Animations
Where Is the Problem?
Good Lock itself and its installed sub-modules:
Technically:
- Constantly running background services
- UI customization modules
- System animations and triggers
- Processes that do not enter deep sleep
All of these continuously create micro-loads on the CPU and RAM.
My Solution: I Removed Good Lock and All Its Modules
What I Did:
- Completely uninstalled the Good Lock app
- Removed all installed modules
- Cleaned unused Samsung system apps
- Used the phone for 3 days with full 0 → 100% charge cycles
- Closely monitored background behavior
Result (Clear and Measurable):
- Only 5% battery drop in 30 minutes
- Almost zero battery drain while idle
- Return to the old, stable battery performance (I can’t even describe that happiness)
At this point, I can say this clearly:
On my device, the issue was not hardware — it was Samsung-originated software.
What I suspected turned out to be true. Thankfully, I found and fixed the issue.
Additional Tests and Recommendations (May Not Apply to Everyone)
Testing with Safe Mode
If you want to be sure:
- Run the phone in Safe Mode
- Observe battery consumption
- Check recently installed apps
- Go to Developer Options → Running Services
- Monitor active background services
These steps help determine whether the issue is app-based or system-based.
Galaxy Watch, Bluetooth, and Battery Relationship
If you use a smartwatch connected to your phone, I recommend reviewing this as well.
My Preference:
- Turn off Bluetooth connection between phone and watch
- Use the watch via Wi-Fi
- Receive notifications over Wi-Fi
This way:
- The phone is relieved from Bluetooth load
- Watch battery performance also improved
Overall, it provides a more stable battery experience.
Screen, AOD, and Other Battery-Draining Details
What I Turned Off:
- Always On Display (AOD)
- Unnecessarily high screen resolutions (I use HD+ 1560×720)
- Samsung Pedometer feature
The pedometer feature:
- Continuously runs sensors
- Consumes battery in the background
Since it runs 24/7, it causes noticeable battery drain. I noticed this through testing.
Network Changes and Signal Strength Impact
After switching my carrier:
- Weak signal
- Reduced call quality
- Frequent call drops
I still experience these issues. (I assume 99.9% of this is infrastructure-related.)
Weak signal:
- Keeps the antenna constantly active
- Increases battery consumption
This is mentioned in many sources.
It may not be the sole cause, but it’s a contributing factor that shouldn’t be ignored.
Power Saving Mode: Not as Innocent as You Think
Based on my personal experience:
- Power saving mode doesn’t always save battery
- It can cause the CPU to behave more aggressively
My Preference:
- Remove unnecessary apps
- Keep the system clean and minimal
This way, I don’t need power saving mode at all.
Final Recommendation: Device Care and Optimization
- Run device care every 2 days
- Restart your phone periodically
- Monitor background apps
- Disable unnecessary system services
These small steps provide serious battery gains in the long run.
Another thing I found during my research is that Microsoft Authenticator (used for two-factor authentication) has reports of high battery usage. However, I personally did not observe excessive battery drain on my device.
If you use it, it’s still worth keeping in mind.
Conclusion: The Issue Is Solved on My Phone
This article is based entirely on my personal experience, research, and hands-on testing.
- Trial and error
- No exaggeration, no assumptions
It may not produce the same result on every device. However, I solved my Samsung S24 Ultra battery issue by uninstalling Good Lock.
I hope this personal experience helps others facing similar problems.
If it helps even one person, it has achieved its purpose.
