Battery lasts longer when charged with cooler.
Hi, my op12 is around 2.5 years old and now at 86% battery. In a normal day I normally get around 4-4.5hr of sot. Remember, I have never done any app disabling. All things on. Except I dont use facebook or insta.
I have alwys found this, that when I put my 18w cooler while charging battery alwys stays longer, but I always forget to take a screenshot. Today I remembered. So here it is, I seem to get around 45 minutes extra before the phone switched off.
What do you think- is my experience is correct? Did any of you experienced the same?
