We only care what you'd notice.
Most phone reviews compare benchmark scores and spec sheets. We compare your phone with a newer one on the things you'd actually feel on a Tuesday afternoon — and then we tell you honestly whether it's worth it.
Not sure which iPhone you have? Check Settings → General → About.
Three possible answers
- Upgrade.
- You'd feel a real difference in at least three parts of daily life — like the screen, the camera and battery life. A tired battery doesn't count, because you can fix that. Or your phone no longer gets the latest iOS.
- It depends.
- There's one real difference (or a few small ones), and whether it matters comes down to you. We list both sides.
- Keep it.
- Day to day, you wouldn't notice much. Keep your money.
What counts as a big difference
We group big differences into areas of daily life: screen, camera, battery and charging, speed, storage, signal and updates. Several improvements in the same area count once.
- Battery life — when a newer phone is rated to last at least 50% longer than yours did when new.
- A worn battery — below 80% health. This one is fixable, so on its own it never means "upgrade".
- Screen smoothness — going from 60Hz to 120Hz. You notice it every time you scroll.
- Storage — moving up from 64GB or less.
- Memory — moving from 4GB or less to 8GB or more, so apps stop reloading when you switch.
- A zoom lens — getting one, or a zoom at least twice as long.
- Signal — moving from an older Intel modem.
- Updates ending — when your phone is expected to stop getting new iOS versions within a year.
Everything else — Apple Intelligence, USB-C, new buttons, satellite features, MagSafe — counts as a nice extra. Plenty of extras can make it "It depends", but extras alone never make it "Upgrade".
Why a battery never makes the decision for you
A worn battery is the most common reason phones feel old. It's also the cheapest thing to fix. So if your battery is the only real problem, we'll say so and show you what a replacement costs. We'll only say "upgrade" if you'd still feel the difference with a brand-new battery.
Where our numbers come from
- Specs: Apple's tech-specs pages for every model, region by region (US, UK and Hong Kong models can differ).
- Memory (RAM) and battery capacity: Apple doesn't publish these. We use figures found in Apple's developer tools and regulatory filings, and mark them Reported.
- Battery life: Apple's video-playback ratings. Real life is shorter for every phone, so we use them to compare, not to predict hours.
- Prices: Apple's own prices and battery replacement fees, plus trade-in quotes from Apple and one or two well-known buyers in each region. We check them every month and show the date.
What we guess (and how to fix it)
We keep it to one question — which iPhone you have — so we fill in the rest:
- Battery health: we assume you bought your phone at launch and estimate normal wear from there. Your real number is in Settings → Battery → Battery Health; enter it on your result and the answer updates.
- Condition: trade-in values assume your phone is in good shape. Cracks or a faulty Face ID fetch much less.
- Your region's model: we assume your phone is the version sold where you are.
- Launch dates: when we mention upcoming phones, the dates are expectations until Apple confirms them. We say so.
What we don't do
- We earn nothing from your decision. No ads. No affiliate links. No commission if you buy, sell or trade in.
- We don't collect your data. Your region and screen calibration are saved on your device only.
- We're not Apple. We're independent and not affiliated with Apple. iPhone is a trademark of Apple Inc.
