Maximum battery life

[NeckbeardSlayer]

Hello all. 

My wife and I have owned the S23 Ultra since April 2023, and I originally spent half the day after opening the boxes back then to carefully adjust all settings to be optimal for maximum  battery life. Including limiting the battery's maximum charge to 85%

Mine is still charging to 85% but hers has now as of today dropped to a maximum charge of 80%

Battery life diminishing is inevitable. But I'm curious what could cause hers to lose that 5% max capacity already?

Anyone have some common ideas or knowledge of issues that might affect hers? 

We can easily swap the phone for an S24 with our provider for $99 in its upgrade and protect plan, but It'd be nice to hold our for a bit longer.

If hers has been updated software to the One UI 6.1
It has changed to 80% now on the maximum battery protection

Hey there

This is correct and is by design by Samsung. Nothing to be concerned about.

80% here, s23 ultra.

I really hope Samsung brings back the 85% option. That is barely acceptable on my S22 base model as it has a small battery and I only use the 100% option when I know I will be unable to charge for a long time. 80& is not so bad for the Plus and Ultra models. But the base models are already lacking at the 100% level.
