When buying a mobile phone, be it refurbished or new there are the usual forces that will push a shopper to choose the smartphone model such as brand loyalty, OS (operating system) loyalty or model upgrade.

Many people will, hence will move from say iphone 6 to iphone 7, or indeed Samsung Galaxy from 6 to 7.A mobile phone will generally improve with each incremental iteration as it builds on the previous model and brings in new features and raise technical specifications.

Many people looking to buy a smartphone will investigate the detail of the tech specs so we thought that we would explain the various, seemingly black and white, minutiae which can lead to a mobile purchase.

Tech Specs Explained

DISPLAY – the main things that people are looking for is screen size and pixel density, Recent models of both the iPhone and Galaxy have not changed screen tech of late though the Samsung Galaxy S8 is almost phablet in size with a 5.8″ screen with 1140x2960 pixels.
Also of note is the type of screen which bears relation to how resistant it may be to scratches and cracking and also how responsive it will be to touch and affect its likelihood of attracting grease. The iphones and the Galaxy come with oleophobic coating. The Galaxy series have Gorilla glass which is considered more durable.

CAMERA – although mobile phone cameras have had a tendency to increase the pixel size with each new model HTC lead the drive to release lower pixel size cameras with larger receptors, hence giving better pictures in low light without the use of flash.
This has, to some extent, slowed down the “numbers game” with more of a focus on ‘real’ picture quality than boasting about the number of pixels.

STORAGE MEMORY – mobile phones come with an array of on-board memory sizes ranging from 4gb to 256gb – with the complexity of the operating system and the amount of ‘bloatware’/ preinstalled and uninstallable apps one can quite quickly find that the memory gets full.
Many Android phones have the facility to expand the memory using an SD card which does, indeed bring greater freedom than that of the iPhone. The iPhone’s pricing structure has been criticised in some quarters as one can pay a large amount for a model with a relatively small increase in memory.
That said, it is possible that, with services and apps moving to the cloud, on-board storage will become less of an issue as music and movies are streamed via Spotify™ and Netflix™ and photos and documents can be stored on Google Photos™, Drive™, Dropbox™, Onedrive™, Apple Storage™ and many other such cloud based apps.
Further the reason some devices (notably iPhones and Nexus )do not have expandable memory is that a greater efficiency in file system look up is achieved with just one storage block, leading to better security and speed of operation.

RAM MEMORY – larger RAM sizes mean that a mobile can think faster, or perform more operations per second. This means that programs or games will render, open and act much faster – making the user experience so much the better. The iPhone 7 comes with 2Gb of RAM, for example. The Samsung Galaxy S7, 4Gb. Of course refinements to operating systems may make his discrepancy less important.

BATTERY – increased RAM, brighter and larger screens have led to more and more being demanded of the battery. It seems, these days, that the mobile battery is always playing catch up with the rest of the phone and, as a result, relative battery performance is not improving.
Recent models may well sport 3000mAh ( the Galaxy S7 ) power, but still may not last a normal day without a recharge.
Some Android phones, unlike the iPhones, have removable batteries so a fully charged spare can be kept in hand which can be useful. Many people also carry a battery pack for recharging their phone whilst on the move.

OTHER FEATURES – there are other features that draw some people such as waterproofing, speaker positioning, fingerprint unlocking and more. Who knows what will come next.


It was interesting to read that consumer / potential buyers searching for the latest models could quite easily be divided into two parties. Google released data based upon searches which showed that whereas potential iPhone buyers ( brand loyalty! ) searched for colour and memory options it was the Android searchers who were more inclined to investigate the more technical aspects of a mobile phone before purchase.

Similarly – many of the numbers bandied around by the manufacturers do not compare directly between models and or operating systems. Basically if you buy a smartphone, be it Samsung Galaxy, iPhone, LG, Nokia, Huawei, Xiaomi, Sony, OnePlus, HTC, Motorola or any premium manufacturer that has been made in the last two or three years you will get a great phone.
