"Google has confirmed that its Battery Health Assistance feature can't be turned off on the Pixel 10 phones," reports Android Authority:

Google introduced a Battery Health Assistance feature on the Pixel 9a earlier this year. This feature gradually drops your phone's charging speed and battery voltage in the name of battery health. This tool is mandatory on the Pixel 9a but optional on other Pixel phones. However, there's bad news for the Pixel 10 series. Google confirmed to Android Authority that Battery Health Assistance is mandatory on the Pixel 10 series and can't be disabled. That means your phone's charging speed and effective battery life will drop over time...

All smartphone batteries degrade over time, resulting in shorter and shorter endurance. Google says the Pixel 8a and newer Pixel phones can withstand 1,000 charging cycles before their batteries drop down to 80% effective capacity. However, this Battery Health Assistance feature essentially reduces the phone's battery capacity over and above standard degradation. This is particularly disappointing as users aren't given a choice in the matter.

It's also disappointing as some rival smartphone makers address battery health concerns by offering more durable batteries. For example, Samsung's top phones can withstand 2,000 charging cycles before dropping down to 80% effective capacity, while OnePlus and OPPO's lithium-ion batteries offer 1,600 cycles before reaching 80% capacity. So there likely wouldn't be a need for a Battery Health Assistance tool if Google's batteries had similar longevity.

"The issue also comes after several older Pixel A series models suffered from major battery issues in 2025..."
