I recently purchased a Logitech K750, and it works great. I pushed the button for the solar app today and realized the batter was at 85%. I hadn't ever seen it drop below 100% before. Well, I decided to throw it in the window to charge up for the first time. I live in Phoenix, so not a cloud in the sky. Just blistering hot sun coming in the window. I went to the movies, watched Godzilla destroy Mothra X2, and now I come back to see... it charged to 86% in 3 hours... The keyboard was hot to the touch from the direct sunlight for 3 hours. Is this normal?? If the charge is this slow, this keyboard will absolutely not work for me.
Has anyone else had that issue?
