Thermal Phone Case,Prevent OVERHEATING in The Sun, Prevent Lower Temperatures to Extend Battery Life, Fits iPhone 8/X/XR/11 Pro/11 Pro Max, Galaxy S9/S10 and Similar Sized Phones-Silver

I brought this case to Death Valley, California for a month straight in August 2023. For you Army guys I'm talking about NTC rotation. My phone did not overheat once. I also took measures such as keeping it off at peak hot hours, putting it in airplane mode, keeping the case in the shade, and not repeatedly putting it in/taking it out during the day (as much as possible). Last time, I was here for a month May/June and my phone would show overheat warnings or tell me it couldn't turn on because it was too hot. That is why I bought this case and it worked great. The velcro becomes degraded after repeated use but it doesn't appear to affect heat protection because the phone never over-heated. I got complete service/signal with the phone in the pouch as well. My phone is a V50thinQ android OS. Lastly, it's a nice way to keep your phone safe from bumps/drops, and it makes it easier to find because of the silver color. I was jostling around all month in and out of big vehicles and running around with my phone in my hip pocket (inside this case) and had no new screen damage. Overall I'm extremely pleased with this case and I will buy a new one when I have to visit extreme temperature regions again. If it did the job here it will do it anywhere.

This pouch kept my phone from overheating during the hot days by the pool/beach in Jamaica.

So far it seems to work well in a hot car. There was one moment that my phone still seemed to overheat when I took it out.

Mine might be defective, however, the Pingketor phone case does not prevent my iPhone from overheating. I had my iPhone in the case in my back pocket while hiking and the iPhone said it must cool down before use even though the end was fastened closed. Another time I was lounging by the pool and had the iPhone in the phone case beneath the pool chair which was covered with a towel and it also overheated that time as well. The only thing I could do was place the iPhone in a plastic bag and dunk it into the pool to regain access. I’m dissatisfied.

Due to my work, I’m often outdoors, and in summer, it's especially frustrating because my phone battery drains so quickly. A friend recommended this phone insulation bag, and it’s been a great help! My phone didn’t overheat at all，and the battery also lasted longer than usual.
