I know a women in family who is a mother, when she got a new iPhone 17 Pro she passed her 14 Pro to husband, who then gave his 13 to their older daughter, and the daughter handed her old Android phone to her younger brother.
That moment made me smile. As someone who’s been following iPhones for years, this kind of “iPhone family chain” is surprisingly common.
And it got me thinking — how long can a basic iPhone actually last before it feels outdated?
A short answer: you can keep an iPhone for at least 5 years, easily. If you no drops, no water, and regular battery swaps, most iPhones last 6 years or more — some people are still using the iPhone 8 today.
iPhone 8 — The Loyal Veteran That Just Won’t Quit
Nine years old, still rocking that Home button nostalgia. It runs the A11 chip, and while it’s far from a speed demon, it still handles chats, music, and light video playback.
You can buy one now for a few hundred dollars — and for students or backup phone users, it’s an unbeatable entry into iOS.
1. Still works for essentials
2. Struggles with heavy apps
3. Expected lifespan: 9 years and counting (if treated gently)
iPhone XR — The People’s Choice
A “legend” among full-screen phones, powered by the A12 Bionic chip. If you need a phone for LCD screen, selfies, and durable build, this phone is the perfect fit for you, and If you’re not a gamer or camera perfectionist, this phone still rocks in 2025.
- Used price: $140
- Lifespan: 6–7 years with care
3. iPhone 11 — The Last Great LCD
The iPhone 11 is beloved for one main reason: that LCD screen. Many users prefer it because OLED can cause eye strain. It also brings an A13 chip, a decent camera upgrade, and incredible stability. This phone is not flashy, but ridiculously reliable.
1. Lifespan: 7+ years
2. Used price: $210–280
iPhone 12 — The 5G Pioneer
The A14 chip and OLED display made the iPhone 12 a true leap forward. Scrolling feels buttery. But this phone always criticized for feeling “too light” and having weak battery life. But if you replace its battery and avoid cheap refurbished units, it’s a sweet mid-tier option in 2025.
- Price: $240–20 used
- Lifespan: 6 years solid
iPhone 13 & 14 — The Sweet Spot
These two are the current crowd favorites. Both use the A15 chip, offer excellent battery life, and stay buttery smooth. The 13 has 4GB of RAM, and the 14 has 6GB — but iOS manages memory so efficiently that it doesn’t matter much.
- With a new battery, these can easily last another 4–5 years.
- You could buy used one in range of $280–$400
If you’re buying today, these are the most sane, future-proof, and value-rich options.
iPhone 15 — Elegance Meets Overkill
This one’s pure beauty. Rounded edges, a matte fused glass back, and the A16 chip built on TSMC’s 4nm process — an absolute powerhouse.
But its price-to-performance ratio is weaker. But more for those who plan to keep it for the long haul.
1. Design: Stunning
2. You can keep this phone for 6+ years
iPhone 16 — The Smart Choice
The A18 Bionic chip, built on a second-gen 3 nm process, adds massive AI computing boosts. It even gets a new camera button, but the design divided opinions — some joke it looks like thermal underwear.
Still, it’s a beast that could easily last you six to seven years.
1. Fast, efficient, slightly overpriced.
iPhone 17 — The Future Flagship
The iPhone 17 with its A19 chip and upgraded 48MP rear + 18MP front camera combo, and a monster in both performance and photography becomes the choice for everyone specially when comes with narrower bezels, a 120 Hz refresh rate, and Ceramic Shield 2.0 glass.
But if you’re eyeing one, wait a year. Prices will dip once the 18 releases are out.
Summary Table

The iPhone 13 or 14 is your safest bet in 2025 — powerful enough for years, yet affordable. And remember — every iPhone has a story.
