Few years ago mobile devices wasn't all that important for most people, you would go to store, choose a small, handsome phone, buy it and that was it.
Nowadays we live in the world of smartphones.
Hard to believe, but, there are thousands of different smartphone models from nearly one hundred smartphone manufacturers.
And as from only cell phones, modern phones have become smart phones and replaced a lot gadgets including music players, handheld gaming consoles, GPS devices, cameras and more, now it isn't as easy to choose right phone for you as it was years ago.
So here is your ultimate walkthrough into choosing the best smartphone that can satisfy you!
You have to choose from Google's Android, Apple's iOS and Microsoft's Windows Phone a.k.a WP.
If you want a smartphone where you're in control, where you can change literally anything anytime you want and use it for everything then Android is right choice.
Also, for mobile gamers, Android is better choice as it let's you easily install APKs, means you can download any app or game outside of official app store, letting you get games not available in Google Play and play games with cool mods.
If you want a fast smartphone with good & simple interface and more security where you don't need to think about customization, then iOS is good choice for you.
In most cases, iPhones are faster than Android phones and gives you more security from malware apps.
Note: don't make mistake, if you're low on budget don't buy iPhone as old iPhones are slower than same priced Androids, anything below iPhone 7 is a bad choice.
As for Windows Phones, I really don't recommend choosing it in most cases.
Microsoft has admitted officially, WP is dead and it will no longer receive any new features, only security updates and bug fixes.
Also, WP lacks many apps and games.
Still, if you're very low on budget, buying Windows Phone 8/10 device instead of 512Mb RAM Android phone may be good choice.
Now that you know what OS is right for you you need to think about hardware.
While choosing screen you need to look at 4 main factors:
Screen technology is quite important factor.
There are two maim screen technologies: oldz traditional LCD and new AMOLED.
AMOLED screens looks more beautiful and colorful, delivering better but less real colors than LCD.
But big disadvantage of AMOLED is durability.
For AMOLED screens "screen burn" - transparent black dots are quite common. And if you drop you phone often, it's nearly guaranteed.
Another issue with AMOLED is loss of quality over time, screen will look much less colorful and sharp after 1-2 years than when it was new.
LCD screens also loose some quality over time but it's really slightly less compared to AMOLED.
One more disadvantage, while it's quite beautiful, AMOLED screen picture is unrealisti.
If you're ok with that, then ignore it.
As for LCD, there are some major LCD types like TTF, IPS...
TTF screens requires slightly less battery power compared to other two, however it's less sharp for HD and above.
IPS has better quality with high resolution but requires more power.
Screen resolution is another very important factor for display quality.
While more pixels gives you better quality, it also needs more battery power and stronger CPU/GPU.
Try not to buy smartphone with resolution less than 720x1280px, HD.
Ideally you should buy smartphone with Full HD resolution, 1080x1920.
2K and 4K screens are usually too much for smartphone, most humans eyes can't see difference between Full HD and 2K/4K 5-6 inch screens.
More resolution = smaller pixels = better quality picture.
That's right but there is interesting factor, the bigger screen is in size, the more pixels it needs.
So, basically, one small size screen with 720x1280 resolution has better quality than much bigger screen with 1080x1920 resolution because bigger screen needs bigger, or more pixels.
That's where PPI - Pixel Per Inch comes im handy, it does not tell you total screen resolution, but amount of pixels per 1 inch.
So if one screen has bigger PPI number than other, definitely, it has more quality picture.
The most common mistake I see people make while choosing camera is looking at MegaPixels.
! MegaPixels does not decide camera quality !
MP is simply picture resolution, how big picture can be without losing quality.
If you compare 8Mp camera picture and 41Mp camera picture on a standard size screen you will see no difference at all, but if you compare them on a large 8K monitor you'll see 8Px picture has lost some quality.
But we don't take pictures for billboards with smartphone camera, right? So you can freely choose any camera with 8Mp or above, however 12Mp or 16 would be better for latest smartphones.
While choosing camera what you want to actually look at is sensor size, lenses, zoom size and software functions like autofocus, smile and face detection, HDR...
If you need smartphone with decent performance, these three hardware elements are extremely important.
Also, better quality camera and screen needs more powerful CPU & more importantly, GPU.
#CPU stands for Central Processing Unit, or as most people call it, processor.
It's responsible mostly for speed if your smartphone.
For modern smartphones, octa-core is best choice, quad-core is also quite good.
For oder devices, dual-core isn't also bad, but try to avoid single-core CPUs.
As for CPU manufacturers, there are several major manufacturers.
In modern hardware, #GPU is part of CPU, all together - SoC - System on Chip.
GPU is specific type CPU only aimed for graphical information calculations.
Your phone needs good GPU for better quality in games and more smooth gameplay.
Generally: Tegra>Adrenk>PowerVR>Mali.
#RAM is what lets CPU be fast and take ages for quick reading and writing of necessity information.
The more RAM you have, the more apps you can run at same time, or in background.
How about listening music while downloading a movie, at the same time installing new app and playing cool game?
