What do you look for first when picking out a newfangled smartphone?Android or iOS ? The central processing unit chip inside ? The size and resolution of the screen ? How many cameras ? You probably have your specification of option , but do n’t kip on these less - consider differentiators .
Internal modem and antennas
Every phone can make and receive calls of course , and manage the stream of information to and from your gadget , but they do n’t all do it equally well . The modem inside your smartphone is responsible for all this wireless dealings , and it ’s one of the specification that ’s deserving see out for , especially as we set out moving to 5G.
The choice of modem order the maximum upload and download speeds you may expect on and off wireless fidelity , and which web you may link to while out of the country , and even whether or not a earphone is able-bodied to include duple - SIM funding or not . Better modem can work well on less baron , meaning more assault and battery life .
Also look for the number of antennas included : a 4×4 MIMO ( multiple input , multiple output signal ) phone has four feeler for four co-occurrent information streams , for instance , while a 2×2 MIMO phone has two . This is one of the conflict between theiPhone XR(2×2 MIMO ) and the iPhone XS and iPhone XS Max ( 4×4 MIMO ) that might not have been at once apparent on launch day .

More antennas typically equates to faster speeds anda stronger sign . Of course , the top - end phones will only get the top - end cellular amphetamine if they ’re also hold up by the networks they ’re connected to , which take us back to 5G — you only really take a 5 G phone once there ’s a 5 thousand web worth tie to .
Unfortunately , modems are n’t all that easy to compare , and maker — Intel , Qualcomm , MediaTek , and others — aren’t always forthcoming about the detail of their products . Do yield attention to the modem and the antenna inside your phone anddo some researchon the model numbers though , as it ’s one of the differentiators between handsets that can have a actual impact on day - to - day use .
IP rating
The IP military rating on a phone ( or any other piece of gadgetry ) refers to how well it can snub junk and water . IP simply place upright forInternational Protection(or sometimes Ingress Protection ) , and is manage by the International Electrotechnical Commission .
The first digit after the IP is “ solid particle ” ( dust ) protection . As far as smartphones are concerned , it goes from 0 , which is no protection at all , to 6 , which is rubble loaded and means no mote can get inside the casing at all .
The 2d digit care “ smooth entering ” ( water ) protection . For telephone , you ’re looking at anywhere from a 0 ( no protection ) to an 8 ( continuous immersion in water ) . Higher numbers are sometimes used ( 9 K means protection against gamy temperature water system gets ) , but for headphone , IP68 is the gold standard .

However , manufacturer do have some tractability in defining what the “ 8″ in IP68 really means , beyond continuous immersion : On every phone spec sheet you should see a reference of a depth and a sentence limit that the earphone can withstand . So thePixel 3 , for case , can last for up to 1.5 meters for 30 minutes .
Smartphone Lord are under no obligation to designate informatics valuation , and may just use terms like “ splashproof ” or “ waterproof”—check the small print to find out precisely what this mean . The good news for consumers is that most new phone now offer rubble and waterproofing criterion .
Charging speeds
If you but plug your speech sound into the wall every night and forget about it , you might never have given much thought to how quickly its electric battery is fill up again — as long as it ’s on 100 percent by the good morning , you ’re good to go . It ’s when you ’re dashing from piazza to office or perhaps only have a speedy 10 minutes to juice up your phone that charging velocity ( and wireless charging stop number ) protrude to weigh .
How fast a phone bang depends on the agency the phone is built , and the superpower of the briny or wireless transcriber you ’re using with it . You need both afast - charging phoneand a fast - charging adapter to get your handset juiced up as speedily as possible — as you ’ll sleep together if you ’ve ever tried to charge your phone from a laptop computer ’s USB port .
Look for the power of your charger , measured in watts ( W ) , which is the current ( often list as ampere or A ) multiplied by the potential drop ( V ) . Also take short letter of the charging charge per unit list on the phone ’s specs . manufacturer like to deploy a bunch of proprietary dissolute charging standards , andthis infographicgives you some idea about how they liken .

Unless you ’re using a wily courser from some unidentified brand , you ’re not conk out to bodge up your earpiece by using a charger that ’s too potent : Today ’s handsets let in safety measures to stop that from happening .
AI engine
If you watched any of the major phone launches of 2018 , you ’ll have date acknowledgment to CPU silicon chip augment with additional hokey intelligence powers — and AI is indeed something that ’s worth looking out for the next metre you ’re choosing a phone .
The internal computer architecture vary between producer , but the basic idea is the same . These AI chips ( or subsets of cow dung ) are design to handle the sorts of calculations needed for machine scholarship , in the same way that graphics chips are design to handle the sorts of calculations needed for pushing pixels to a display .
One of the prosperous examples to understand is image recognition : tell apart which of your picture include a hot dog , or being able-bodied to tell when you ’re shooting a close - up of flowers ( so the photographic camera app can intelligently adjust the camera options to cope with ) . Being able-bodied to quickly know your voice through AI is another model .

All the top chipsets from all the openhanded public figure now admit some kind of AI processing , like the Neural Engine on board the A12 Bionic mainframe insidethe 2018 iPhones . One area where you should see the difference , besides the ones we ’ve already mentioned , is in the fastness and smoothness of augment reality apps .
While it ’s difficult to compare one AI engine against another , it ’s an extra reason to go for a newer , more powerful flagship phone : More of the machine learning processing expect can be done on board , rather than being offloaded to the cloud . And as more apps are build for these chips , your sound is more probable to keepy up with the tech .
HDR support
HDRbrings with ita broader scope of color , a full-bodied picture , and more detail in the unaccented and dark parting of a display . To view videos and photos in HDR , you need an app that can exhibit message in the right data formatting ( like Netflix or Amazon Prime Video , as long as you ’re on the right architectural plan ) and a telephone set that offers HDR support .
And there are now many of them . You ’ll often see mention to HDR10 , one of the most democratic HDR formats ( chiefly because it does n’t be anything to licence ) . There ’s also the wide supported Dolby Vision take on HDR , which brings with it more color and unspoiled direct contrast than HDR10 .
The SamsungGalaxy Note 9 , to give you one deterrent example , uses HDR10 . TheiPhone XSfrom Apple , meanwhile , plump for both HDR10 and Dolby Vision . As you could see , it can get rather complicated rather quickly , but it ’s still worth calculate out for on phone glasses sheets .

To add to the confusion , you need a phone specifically supported by your preferred apps . HDR - enable Netflix wo n’t work on every HDR - enabled telephone set , although most raw models are covered : you may check out the lists forAndroidandiOS .
HDR is now fairly well launch as a standard on phones and television band likewise now , so chances are if you ’re purchase a young French telephone it ’s plump to do with HDR musical accompaniment . Pay attention to mentions of the tone of the display panel and its resolution in reviews as well , as these factors will be just as crucial for a good viewing experience .
