You might be tempted by the iPhone 15, but if getting a new phone isn’t urgent for you, it’s smarter to wait.

Even though Apple hasn’t set a date for their big fall event or said a new iPhone is coming, signs point to a new iPhone 15 coming out in September. So, it’s a good idea to wait before getting a new phone, even if your current one is almost done for.

Apple’s planning an event on September 12. Reports say they’re likely to reveal new devices, including the iPhone 15. The new iPhones will have quicker computer chips, new charging ports, and some will even have a fresh look.

If you’re not bothered about new features, think about the cost. New iPhones are pricey, but older ones get cheaper. Right now, you can get an iPhone 12 or 13 for less than their original prices. When the iPhone 15 comes out, expect the iPhone 14 to get cheaper, too.

The idea of having the latest iPhone every year might be tempting, but it’s worth considering why you might not actually need to upgrade so often. The financial strain of an annual purchase can add up.

Additionally, the improvements in new models are often incremental—think slightly better cameras or modestly faster chips—so you’re not usually missing out on revolutionary features. Also, continuously buying new phones contributes to electronic waste, which is a growing environmental concern. Lastly, today’s iPhones are built to last and often receive software updates for many years, so your current phone is likely sufficient for your needs.

All in all, unless you have a compelling reason, skipping a year (or more) between upgrades can be a smart choice both for your wallet and the planet.
