Apple releases a new iPhone almost every year, usually in September
Apple typically announces a new iPhone model in mid-September, with devices arriving in stores about two weeks later. The company sometimes releases a second wave of models in October or November. The exact date shifts year to year, but September has been the pattern for over a decade.
When a new model launches, older models usually drop in price. The previous year's flagship model typically falls by $100 to $200, and models from two or three years back may fall further or disappear from Apple's official store entirely. Carriers like Verizon, AT&T, and T-Mobile often run trade-in promotions around launch week, offering extra credit if you turn in an older phone.
The announcement itself happens at Apple's headquarters in Cupertino, California, streamed live on Apple's website. The company shows off new camera features, processor speed, battery life, and design changes. Pre-orders usually open the Friday after the announcement, with shipping beginning the following week.
Key Takeaways
- New iPhones launch in September most years, with pre-orders opening about a week after the announcement.
- Older iPhone models drop in price when a new one releases, sometimes by $100 to $300 depending on age.
- Carriers offer trade-in deals during launch week, but the offers vary by carrier and change frequently.
- You do not have to buy a new iPhone when one releases — your current phone will continue to work and receive software updates for several years.
How to know what changed from the previous model
Apple's website lists the technical differences between models: camera megapixels, processor name, screen size, water resistance rating, and battery life in hours. These specs tell you whether the upgrade matters for how you actually use your phone.
If you take photos in low light, a camera upgrade might matter. If you use your phone for video calls or gaming, processor speed affects performance. If you keep your phone for five years, battery capacity and software update support matter more than this year's new color. Apple publishes how many years of software updates each model receives — currently five to six years for most iPhones.
Tech review sites like The Verge, CNET, and Wirecutter test new models against older ones and explain which upgrades are real and which are marketing. Reading one detailed review takes less time than scrolling through Apple's spec sheet and tells you whether the new model solves a problem you actually have.
When to buy: launch week versus waiting
Buying during launch week means you get the model you want without waiting for stock to replenish. Demand is highest in the first two weeks, so if you want a specific color or storage size, ordering early reduces the chance of a three-week delay.
Waiting three to six months means prices drop and reviews accumulate, so you know whether the model has widespread problems. You also know which colors and storage sizes are actually available, rather than guessing. The trade-off is that you miss carrier promotions, which are usually strongest in the first month.
If your current phone works fine, waiting costs nothing. If your phone is broken, slow, or no longer receives updates, buying sooner makes sense. If you are on a carrier payment plan, the monthly cost is usually the same whether you buy at launch or later — the carrier spreads the price over 24 or 36 months either way.
What happens to your old iPhone
You can trade it in to Apple, a carrier, or a third-party service like Gazelle or Back Market. Apple's trade-in value depends on the model, storage size, and condition — a working iPhone from two years ago might be worth $150 to $300. Carriers often offer more during launch week as a promotion, sometimes adding $50 to $100 extra credit.
If your old phone is broken, trade-in value drops sharply or disappears. Some services still accept broken phones for parts recycling, but you will not get cash. Selling privately on Facebook Marketplace or eBay usually brings more money than trade-in, but takes more time and carries more risk of scams.
If you keep your old iPhone, it still works. It will not receive new iOS versions after a certain point — usually five to six years after release — but it will continue to run the last version it received. Apps may stop working as developers drop support for old iOS versions, but this happens gradually over years, not overnight.
Carrier deals and financing options
Verizon, AT&T, T-Mobile, and regional carriers run promotions during launch week. Common offers include bill credits spread over 24 or 36 months, or a flat discount on the phone's price. The catch is that these deals usually require you to keep the phone on that carrier's network for the full payment period — switching carriers early may cancel the remaining credits.
Financing through a carrier is not the same as a loan. You own the phone immediately, but the carrier owns the right to the credits if you leave. If you think you might switch carriers within two years, read the fine print before committing.
Apple also offers financing through Affirm or its own Apple Card, spreading the cost over 12 to 24 months with or without interest depending on your credit. These options work with any carrier and do not lock you in, but the interest rate depends on your credit score.
Storage size and color decisions
Storage size matters if you take a lot of photos or videos, or download many apps and games. Most people use 128GB or 256GB without running out of space. If you stream music and video instead of downloading, or use cloud storage for photos, you can get by with less. If you edit video on your phone or keep years of photos locally, 512GB or 1TB makes sense.
Color is personal preference, but it affects resale value. Black, white, and silver sell faster and for slightly more money than unusual colors. If you plan to keep the phone for five years, color does not matter. If you might sell it in two years, a neutral color is safer.
Availability varies by color and storage size during launch week. Popular combinations sell out first. If you want a specific combination, pre-ordering on launch day increases your chances of getting it within the first shipment.
Software updates and long-term support
Apple releases a major iOS update every September, usually compatible with iPhones from the past five to six years. Security updates come out monthly or as needed. Your phone will receive these updates for free over Wi-Fi or cellular, and you can delay them if you want to wait for reviews of any problems.
Older iPhones stop receiving major updates at a certain point, but they keep getting security patches for a year or two after that. An iPhone that no longer receives updates is still usable, but it becomes riskier to use for banking or passwords because security holes will not be fixed.
If you keep a phone for more than six years, plan for the day it stops receiving updates. At that point, you either accept the security risk, use it only for offline tasks, or replace it. This is one reason buying a new phone every three to four years makes sense for most people — you stay within the update window and avoid the security gap.
Frequently Asked Questions
Do I need to buy a new iPhone when one comes out?
No. Your current iPhone will continue to work and receive updates for several years. Buy a new one only if your current phone is broken, too slow, or no longer receives software updates. A working iPhone from three years ago is still a capable phone.
Will my old iPhone still work after a new one launches?
Yes. Older iPhones keep working indefinitely. They stop receiving major iOS updates after five to six years, but they continue to run the last version they received. Apps may gradually stop supporting old iOS versions, but this happens over months or years, not immediately.
What is the best time to buy an iPhone?
If you need a phone now, buy now. If your phone works fine, waiting three to six months means lower prices and more reviews. If you want the newest model and do not mind paying full price, launch week is when stock is most available. There is no universally best time — it depends on your situation.
Can I use my old iPhone as a backup or second device?
Yes. You can keep it as a backup, give it to a family member, or sell it. If you keep it, make sure it still receives security updates. An old iPhone without updates should not be used for banking or passwords, but it works fine for music, photos, or offline tasks.
How much will my current iPhone be worth when I trade it in?
Trade-in value depends on the model, storage size, and condition. A working iPhone from two years ago might be worth $150 to $300 at Apple or a carrier. Broken phones are worth much less or nothing. Selling privately usually brings more money than trade-in, but takes more time.
