These are the changes I want made:
1) Change all the dark grey color labels to a very light blue color for better contrast.
2) Remove current weather icon from upper left corner then make all three temperatures number the sames size which is inbetween the large temperature and the two small temperature font size. Make the low temperature the same blue color as the sunset cloud icon on the right of the second row and make the high temperature the orange color of the sunrise icon on the left. Leave battery indicator as-is although I'd prefer if the icon change to yellow when the battery is at 10% or below if not very hard. (Removing the weather icon will allow the height of the second row below to be increased as the weather icon is responsible for the height of the first row)
3) Make the numbers above the AQI, UVI, WSE, and HUMI levels in the second row slightly larger. If there needs to be more horizontal room, you can take the sunrise time on the left and sunset time on the right and stack the numbers on top of each other and put them on one side and remove the sunrise and sunset icons.
4) Make the day of week and weekday font to the left of the time slighlty larger. Remove the cakendar icon if necessary.
