Hello fsal62,
Thank you for using Apple Support Communities! I understand that the display brightness dims unexpectedly on your iPhone 6s Plus. You've come to the right place for a resolution.
Auto-brightness is a feature that is enabled by default on your iOS device, and it could be causing the brightness of your iPhone display to lower automatically:
Adjust the brightness on your iPhone, iPad, or iPod touch - Apple Support
Specifically, follow the steps in this section to check if auto-brightness is enabled:
If auto-brightness is turned on, try turning that feature off and let us know if the behavior still occurs.
Take care!

About brightness levels
iOS devices use an ambient light sensor to adjust brightness levels based on the light conditions around you. The sensor lowers brightness in dark locations and raises brightness in light locations. The auto-brightness feature is on by default.
When auto-brightness is on, you'll notice that your device's brightness slider moves according to changing light conditions.
In iOS 11, you can turn auto-brightness on or off in Settings > General > Accessibility > Display Accommodations. In iOS 10 and earlier, go to Settings > Display & Brightness.
If auto-brightness is turned on, try turning that feature off and let us know if the behavior still occurs.
Take care!
