Android vs iOS

The first step when searching for a new phone is to pick which operating system you want to use. These come pre-installed, and can vary depending on the make and model of your device. Currently, the most well-known operating systems are iOS (developed by Apple) and Android (developed by Google). But which system is right for you?

If simplicity is what you're after, you may prefer iOS over Android. In true Apple style, the interface for iOS is characteristically minimalistic, however this does mean it’s less customisable than its Google counterpart. While you can change minor elements to your Apple iPhone, you can reconfigure almost every aspect of your phone’s appearance with Android, provided you download the right launcher app.

Speaking of apps, when you buy a mobile phone with Android installed, you get far more programs to choose from than if you go for an iOS phone. There are almost 3.5 million apps on the Google Play Store, compared with 2.2 on Apple’s App Store. However, due to frequent iOS updates and stricter inspections on apps, many people believe that iPhone apps are more secure than those on Google Play. So, if security is a determining factor for you, we’d recommend choosing iOS.

How to choose the right phone for you

Once you’ve chosen your favourite operating system, it’s time to pick the make and model. Our sellers have an amazing selection from the biggest smartphone brands, including Samsung, Huawei, OnePlus and Google. But with so much choice on offer, how do you choose between them? The best way to choose the right phone is to think about what you’ll use it for the most.

Are you a certified show binger? Buying a phone with a large screen and a super sharp resolution will let you see every detail. If you want to use your phone all day without needing a charging top-up, look for one with a high-capacity battery and a smaller, more energy-efficient screen.

If you want to hone your photography skills before buying a full-sized DSLR, or you want every candid night-out photo to look great on the ‘gram, you’ll need a pro camera phone. The best camera phones have extra lenses for ultrawide and close-up photography, and photo improving algorithms that make blurry photos sharper and light up photos that are too dark.

How you use your phone will also affect whether you should buy a SIM free phone or get a contract. Buying a phone with a contract has less upfront cost, but you’ll likely be restricted to the amount of data and minutes that the contract allows. If you chew through gigabytes of mobile data a month (or if you rarely use 4G at all), getting a SIM free phone lets you find the perfect contract later.

Used and refurbished phones

Want to pay less for the latest tech? Check out our used and refurbished departments to find the best mobile phone deals! Showcasing everything from the latest releases to slightly older models that still pack a punch, you’ll find quality phones at an irresistibly good price - treating yourself has never been so guilt-free!

Wondering what the difference between a ‘used’ and ‘refurbished’ phone is? While they share some similarities in the fact that they’re both second-hand, it's important to know the difference when making your decision. To be considered ‘refurbished’, a phone will have been rigorously tested and repaired to like-new condition, while a ‘used’ device will often come directly from the previous owner.

While you can get a great price on a ‘used’ phone, if you want the benefits of a like-new phone with added peace of mind that it’s been tested, repaired, and wiped of previous data, we’d recommend choosing a ‘refurbished’ model. Browse our full selection to find top phones from brands like Apple, Samsung, Huawei and more!

Protect and personalise your phone

To keep your smartphone in prime condition, you'll need the right mobile accessories - and we have everything you need to kit out your device at OnBuy!

If you want ultimate protection, look out for tough mobile phone cases with trapped air pockets to cushion your device and a rigid plastic outer layer to prevent cracks. Or, for a more sophisticated look, try out one of our wallet cases instead. Not only do these cases look chic and sophisticated, they protect both the front of your phone as well as the back, and usually contain handy card slots as well. Don’t forget to explore tempered glass phone screen protectors - after all, you don’t want to be driven to distraction by a hairline scratch!

That's not all, we can also ensure that your smartphone never runs out of charge with our extensive selection of power banks. It’s chock-full of high-capacity batteries that will give your device a couple of extra hours of juice - no matter where you are! Equipped with cables to suit any kind of charging port - from USB-C to Lightning - it’s never been easier to keep your phone topped up while on the go. Explore our whole range to find all the accessories you need to keep your phone in top condition for longer.
