The iPhone 13 range is fast approaching, so if youre in the market for a new iPhone you might be wondering whether Apples next flagship is worth waiting for, or whether you should just buy an iPhone 12 now.To help you answer that question weve looked at the key considerations, including how much of an upgrade the iPhone 13 range is rumored to be, how long youll actually have to wait for it, and how differently the new and old phones might be priced.Ultimately, theres no definitive answer as to whether you should wait or not, but with the help of this article, you should have a clearer idea of which choice is right for you.The iPhone 13 isnt far awayThe iPhone 12 range won't be Apple's newest phones for long (Image credit: TechRadar)The most obvious argument in favor of waiting for the iPhone 13 is that its really not very far away now. The exact release date hasnt been confirmed, but based on Apples past form and the current rumors, were expecting the iPhone 13 range to land in September, with an announcement probably in the first half of the month and the release of the phones in the second half.So at the time of writing were talking a few months, which isnt much considering theres a 12-month gap between each model.At this point wed always advise waiting for the new model unless you can get a current one at a significant discount – which in the case of the iPhone 12 range youre unlikely to, as they hold their prices well. Though you never know, there could be some discounts on Amazon Prime Day.Upgrades could be minorThe iPhone 13 range might not offer much more than the 12 Pro Max (Image credit: TechRadar)On the other hand, this year more than most it sounds like the new iPhone might not be much of an upgrade.While nothing is certain yet, leaks point to a similar design and screen (albeit with a 120Hz refresh rate on the iPhone 13 Pro and Pro Max and a slightly smaller notch), plus a fairly modest power upgrade, marginally bigger batteries, and slight tweaks to the camera, including a LiDAR scanner for all models, rather than just the Pro ones.We may see some bigger changes, but at the moment this sounds more like an iPhone 12S than an iPhone 13, so you might not miss out too much by opting for the older model.Long-term supportExpect years of software updates whichever model you choose (Image credit: TechRadar)The iPhone 12 range likely still has many years of software updates left in it too, so you wont be left behind on that front. Unlike Android where you only usually get two years of updates (or three if youre very lucky), Apple keeps its phones up to date for a long time. Indeed, when iOS 15 lands later this year it will be available for every model from the iPhone 6S onwards.Couple that with a chipset thats still arguably more powerful than any found in an Android phone, and youre looking at a handset with a lot of life left in it.Prices will dropGet ready for the iPhone 12 to get cheaper (Image credit: TechRadar)Even if youve decided you dont want the iPhone 13 though, it could still be worth waiting for the new phone to launch, as prices of the iPhone 12 range are sure to drop when it does.As an example, the iPhone 11 started at $699 / £729 / AU$1,199 when it launched, but now Apple sells it for $599 / £599 / AU$999, so well likely see a similar drop for the iPhone 12. Some models of the iPhone 12 range might be discontinued with the launch of the iPhone 13, but even then third-party stores are sure to still have stock that theyll try and shift at a discount.Plus, by waiting, youll be able to make a more informed decision, as youll know exactly what the iPhone 13 offers, and how much cheaper the iPhone 12 could be.Wed suggest that a wait-and-see approach is best, as its hard to recommend paying full price for a phone that will be superseded in a few months, even if the new model isnt a huge improvement.But if you really cant wait then you wont go wrong with any of the iPhone 12 models – theyre all great phones, and probably will be for a long time.
