Introduction
Use this guide to re-apply thermal paste to your phone.
The processor in your phone might be small, but it generates a lot of heat. Thermal paste helps transfer this heat from the processor to another part of the phone where the heat can dissipate over a large surface (usually the frame or a cover). When you disassemble your phone, you can often find the goopy opaque thermal paste above or below the motherboard.
Your phone will usually work without thermal paste. However, it will overheat faster and may slow down to keep itself cool. Reusing thermal paste is better than nothing, but should only be done if you don't have access to thermal paste for the moment. Apply new thermal paste to keep your phone working safely and at full capacity.

Your phone is less demanding than a full-size CPU in terms of heat transfer, so you can use any regular compound thermal paste.
