1: Smartphones with quad-core and octa-core processors are faster
All every one believe the higher the core number the faster the device will be which is not true. Apple’s iPhone 6s with a two-core processor is way faster than any 8-core processor Android smartphone in the market.
If your smartphone has multi-core processor then it is not necessarily going to be the fastest phone. The quality of the cores is what matters, we all know that quality is always better than quantity. Processor speed forms only a small part of smartphone speed and it depends on so many other factors.
2: Killing Apps with Task Killer will speed up your smartphone
It is a fact that you try to kill App which you are not using hoping it will free more memory space. Actually, apps are cached in RAM which only helps you to get to the apps more quickly.
Your Android smartphone actually allows apps to run in the background with fewer restrictions. The apps in your background are usually frozen and use minuscule memory.
3: More RAM is better
iPhones work fine with just 1GB or 2GB RAM while Google’s Nexus 6P with 3GB RAM is considered fastest Android smartphone available today. But believe it or not, if you are an Android fanboy, you will always look out for more RAM while buying your next Android smartphone.
The fact remains that your smartphone will hang even if it has 6GB RAM if you have not optimised your phone correctly. Try opening and playing 10 videos in Google Chrome in different tabs on your 6GB Android smartphone and you will see what I am talking about.
4: Only use smartphone manufacturer’s charger
I believe smartphone manufacturers are using this one to make people buy there product. The truth is you could use any charger built that matches the battery specs of your smartphone. Yes, using the original company manufactured charger is always best but you can use other compatible chargers without much difference.
If you carefully notice different time results with different chargers, you will find that there is not much difference in the company made charger and a different compatible one.
5: More Megapixels, Better Camera
This is a "big lie" as some people will describe it, smartphone manufacturers are just using this to make you buy their products. The quality of photo mainly depends on how much light the sensor is able to take in.
Better cameras actually have bigger image sensors. Sometimes even a 5 megapixel camera with better sensors gives better photos than ordinary 13 megapixel camera.
