Where to see battery health?

How can I tell the battery health? The factory capacity is 4000mah, but the battery gets weaker as time goes on. 

Apple iPhone tells you current maximum capacity and charge cycle count. Does Samsung show you any of these information?

You are welcome!

It's now part of the diagnostic tools under the Support tab of this app.

Is this showing the factory capacity or the current capacity? Mine shows 4000 mah, which is the factory capacity, doesn't seem like current capacity.

[Dan2023]

I think you may have to run the battery diagnostics first.

I bought a used S25 on the web, and after running the battery test in this app, the capacity number is the same as the factory spec for s25, so I am doubting it is showing the current capacity. Is your capacity number the same or less than the advertised?

Then you got what you paid for.

Well, I don't know if I did... As the seller promised the battery is above 80% health, and I don't know how to verify.

This is less than meaningless information!

We should be able to see exactly the same battery information that is standard information that they see in the EU by law. Date of manufacture,( important information, has it been stting on a self) cycle count, and health in the form of percentage.

It shouldn't take an act of congress to see this information that is available on iPhones and now Pixel Phones in Android 16.

It does not do what Apple can, but you can look at the battery information, see the the size of the battery as sold (like mine for my S25U is 5000mAh typical). Open settings, go down to about phone, then battery information. You will get the typica battery capacity and also an explanation of its testing In my device the explanation say it has a rated capacity of 4855mAh.
