Abnormal battery drain

[userpojeebF2lP]

I'm experiencing abnormal battery drain courtesy of "downloads" and.I can't figure out why this is going on.

Anyone have ideas as to potential solutions?

Sorry you're experiencing this.

You may have downloaded an app, malicious or otherwise, that is continuously downloading files to your device in the background. Are you able to see the downloaded files in your file manager? That may or may not be able to help you identify the source.

You could try booting into Safe Mode to see if the issue persists. If the issue resolves in safe mode, a third party app is the culprit and you will need to identify that app so you can delete it. If it doesn't resolve, there may be a deeper issue.

Assuming the issue resolves in safe mode, start by uninstalling any questionable apps. anything that isn't from a well-known, reputable developer.

If you are unable to locate the culprit, you may need to attempt a factory reset.

How can I find the downloaded files?

[CEParsons]

Open the "My Files" app and navigate to downloads. You may or may not see the files there, depending on what the specific issue is.

If there are files there, it may help you identify which app is causing this.

I've only downloaded some videos from Twitter using TwitterVideoDownloader.

I am not familiar with that particular app, and I am not an X/Twitter user, so correct me if I'm wrong... video downloading is supposed to be a paid feature, correct?

I would be suspicious of any app that serves to circumvent paid features. Apps of this kind often offer some kind of utility and do what they say they do, but also hide unsavory/malicious things underneath.

Personally, I would recommend deleting that particular app, as well as any others that are not from reputable devs such as Samsung, Google, Microsoft, etc. until your issue is resolved.

That's a website, not an app.
As I said in another comment, this issue seems to have started not long after my phone got the One UI 8 update, which happened for me on 09/28/25.

See my comment above if you believe it is directly related to the update. 🙂

[userpojeebF2lP]

From the looks of it, I think this battery drain issue started happening around the same time that my phone got the One UI 8 update.

If you believe it is related to the update, Have you performed these steps for routine maintenence?

☆ Follow Samsung’s Best Practices Guide

In particular, clearing device cache is an important practice in order to clean up junk files and keep things running smooth.

See the guide here: https://us.community.samsung.com/t5/Tips-Tricks/Best-Practices-After-an-Update/ba-p/3200871?src=Shar...

☆ Use Samsung’s Good Guardians

Download Good Guardians and run its various modules. These modules optimize performance and can identify unusual behavior.

Additionally, Galaxy phones have an adaptive battery feature that uses machine learning to optimize battery consumption based on your usage.

After a major software update, this feature resets and needs to relearn your usage patterns. You may notice diminished battery life for a week or so while this process takes place.

The increased battery consumption may or may not be related to downloads associated with the update.

At any rate, I would still recommend deleting any questionable apps from independent or unknown developers until the issue is resolved.
