Hi ubedulla777,
Thanks for coming to Apple Support Communities for help with your iPhone today. It sounds like you are concerned about the battery, screen brightness and temperature.
At 99% the Maximum Capacity is still well within spec. Please see this page for further explanation: iPhone Battery and Performance. A replacement battery isn't recommended unless the percentage is around 80%. However, you should still check for any battery messages in Battery Health.
There are also a few reasons the iPhone could be getting warm: Keeping iPhone, iPad, and iPod touch within acceptable operating temperatures.
For the brightness issue, see: Adjust the brightness and color temperature on your iPhone, iPad, or iPod touch. Is Auto Brightness on?
"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 the brightness slider on your device moves according to changing light conditions.
You can turn auto-brightness on or off in Settings > Accessibility > Display & Text Size. To reset the auto-brightness settings, turn off auto-brightness and then turn it back on. "
Have a fantastic day!
