Your Samsung phone or tablet suddenly started Galaxy only charge to a maximum of 85 percent? Is this a bug or something broke? No, it's a feature called Protect Battery. And you can turn it off or on if you want.
You could have turned on the function yourself by mistake, someone else could have turned it on for you, it could have been activated even after a system update. But the result of all steps is the same - you will not get more than 85% of the battery capacity into the device. But why is that so? Simply to extend the life of the battery, since the last part of the charge cycle is the most demanding on the battery, so Samsung thought that if you want to keep the battery in the best condition for the longest time, you should be able to just skip this.

Does it have any real effect at all? Is it worth it if I change my phone every two years? Because losing 25% of the battery on such a small capacity is not very positive for me...
Purely technical - it's 15%, not 25%.
Simple help. Just turn off the phone for a period of time from 83% and then it will charge to 100%. Then turn it back on. Sometimes the Pixel 5 does this to me too, .
On new Samsung models with new updates, in the next battery setting in the settings there is an item "protect the battery" where 85% is mentioned as the upper limit. Check if you have this item active.
