Protectm Revolution Cool Pad 2.0 for Smartphones (Pack of 1)

First things first, I hate long reviews so I'll state my points and GTFO.This works simply like any Heatsink/CPU combo does. The graphite actcs as a heatsink and the tape is also heat conductive so by slapping this on the back of your phone near the processor, you increase the surface area of which the heat dissipates and how fast it does.It works pretty well if you put it over the processor area of your phone. I have a Z5 Premium House heater and while it still gets hot, I don't lose performance due to intense gaming sessions.The surface area is kind of small, I wish it spread out more.The "Cool Pad backing" lasted like 1 day before starting to peel off. After week 1 I just peeled it off to expose the graphite underbelly. It didn't lose any performance, but 1 Star for uglyness.It came packed well with ... instructions...? I mean it's a sticker, come on people.TL;DR:Overall I'm happy, but I wish it didn't look so bad with the back off. It's just a graphite square now on the back of my phone. I may just buy a not clear phone case and deal with it, but I shouldn't have to. Sorry I don't have any stats but honestly I believe in the "eye test" over "Well studies say..."Disclaimer: By no means is this a miracle worker. If you want a phone to work great inside of a sweatshop while running benchmarks on your phone or playing any graphical intensive game - its not going to work. It will help though if you put it on a cool surface with this attached. I have a Stainless steel "odor bar" which is always cold I lay my phone on during intense sessions, and with this it helps transfer the heat from my phone to this bar, which then makes my phone cooler. If the bar gets hot, I flip it over.

Doesn't work, blocks GPS signal. If anything it makes the phone hotter. Also not a graphene sheet, it's a foil sticker with powdered graphite and then a plastic sticker on top.

did not help at all.. my phone did ok with them. but my husbands phone did not help at all.

Ok, I've only used it for one day, but I can tell that it's making a difference. I just put it on the back of the phone, not inside. I don't now what 5 degrees C feels like, but this seems like more.

it works, but wish it was larger. it's only 2 inches tall, too small

Worked to keep my phone cool when the battery got to hot from apps

There should not be a market for this kind of product at all. It's up to the cell phone manufacturers to use safer, better built batteries that won't catch fire or have a melt down than for us as customers to dismantle our phone to put a sticker on it to make them "cooler"

The product fell apart within a month of having it. I placed it directly on the battery and it did not offer a significant change in temperature.
