6 Ways To Prevent Your Android Phone From Over Heating..

This is the most common problems that arises in every android phone and tablet . This type of overheating is not at all a problem and you can control your device to produce less heat by controlling your usage of apps, the way how you use it. Follow these tips to make your android to generate less heat.
Steps 1. Uninstall Unnecessary Apps : This is not rocket science folks, the more apps you install, the more heat will be produced by your phone’s circuit board. Simple uninstall apps that you do not use, because these apps always run in background and suppose if you want to play games then these apps escalate the heat generated by the CPU & GPU. Don’t skip this crucial tip.
Step 2. Clear The Cache & Junk Files : Use clean master app to clean junk and cache files from your android phone or
tablet. Cache is the immediate data that is used by the CPU to reduce RAM access. If cache is always the CPU will have to work harder to access the data, result is unnecessary heat produced.
Step 3. Use a RAM Booster App : Use clean master app to free up some RAM/memory. High memory usage means many apps running in background. Clearing the RAM will stop the system apps that makes high CPU usage. Less CPU usage means less or no heat.
Step 4. Tips On Using 4G/LTE/3G Networks & Wi-Fi Hotspots : If you are using 3G or 4G networks on your android then make sure that the network reception is always good. Because low network signals lets the android CPU work harder and also the battery will drain faster and getting hotter as the network signals stays weak. So move in an area where the 4G LTE network reception if full.
As you know that 3G and 4G can be converted to Wi-Fi hotspots, see this tutorial . The Wi-Fi hotspot itself used along with the 3G/4G network with weak network signals will overheat the android phone very badly to an extent where you will not even want to hold the phone in your hand due to the heat produced.
So, always make sure that your cell phone or tablet is receiving good 3G/4G network signals in order to prevent overheating.
Step 5. Set Network Mode To GSM : When not required set your network mode to ‘GSM’ instead of ‘WCDMA’ or ‘LTE’. Because GSM always receives good network signals.
Step 6. Undervolting The CPU : This is for advanced users, by rooting your android phone you can undervolt the CPU, so that CPU will consume less power. But this a big procedure and I can't explain it here. Go to XDA forum and search about this.
