If you are searching for a new smartphone chances are you will ultimately have to make a choice between iPhone or an Android handset.
Apple's iPhones have long been among the most popular devices and the newly released iPhone X has created a buzz around the high-tech new flagship handset. But there are still a number of brilliant and popular brands to choose from if you don't want to go for an iPhone.
There has probably never been a better time to look at buying an Android phone. There are only a handful of choices when buying an Apple phone, but devices running on Google's Android operating system offer far more choice and variety and some of the best phones of recent years come from the likes of Samsung, Google and OnePlus.
Relentless announcements of new smartphones can be quite overwhelming, so there are key things to consider when looking to upgrade.
Should I buy an Android phone or an iPhone?
Although there are plenty of great reasons to buy an iPhone Apple's phones are not for everyone, and given that the new iPhone X costs up to £1,000 many people will be looking at other options.
Android is used by more phones and tablets, giving you greater choice when picking your phone and models such as the Samsung Galaxy S8 are market leaders in the technology they offer.
So if you want a bit more choice or a cheaper option, as well as the ability to share data easily across other Android phones and tablets, this operating system might be the right one for you.
What should I look for in an Android phone?
Key technical specs you should be looking for in your smartphone include basic choices such as screen size and battery life to performance indicators such as processing power and storage.
- Screen size: Current sizes range from just under 5 inches to close to 6 inches for screen size, which can be quite large to hold in the hand.
- Battery life: Any phone with significantly more than 24 hours is considered very good. Many manufacturers will judge battery on "talk time", but the phones will actually last days if left on standby.
- Storage and memory: Lower spec smartphones will have around 2GB of RAM, the memory space which makes the phone run more quickly, although better models will have closer to 4GB or better. Expect at least 32GB of storage, look for 64GB or more for a price.
- Camera: Most smartphones will take great pictures and high-end models compete to offer the best cameras. Megapixels (MP) are not everything, but they can create shots with greater close-up details.
- Operating system: Look for models with the latest Android 8.0 operating system for the most safe system, although some still come boxed with Android 7.1.
What should I look for in my phone contract?
While you can simply break down phones in terms of handset price, many providers in the UK offer great deals to pick up new phones for far less.
Many smartphones are available for free if you agree to a two year contract. From there, you will be charged for the number of texts, minutes and the amount of data you use.
Phones that are a year or two old may only set you back £20 a month over a two year period for basic levels of minutes and data. The latest flagship handsets, however, will probably cost more than £40 a month, and may also include an upfront cost for the phone as well.
How much should I pay for an Android phone?
The cheapest decent Android phones will cost from £100 for most of the major brands. These will phones running on Android can still be high quality, just with less power and storage.
Mid-range phones will cost between £250 to close to £500, phones from OnePlus, Nokia and Motorola tend to fall into this category. High-end phones will have the latest dual cameras, huge storage and powerful specs will push you to part with £500 or more. £500 or more.
