How long should a phone realistically last?

Four to six years is now realistic for a flagship. Major makers ship 5 to 7 years of software updates on recent models, and hardware generally outlives the battery. The practical limit is usually battery degradation — most lithium batteries drop to about 80 percent capacity after 500 to 800 charge cycles, which is roughly two to three years of typical use.

Is a battery replacement smarter than an upgrade?

If the battery is your main complaint, almost always. An official battery replacement costs around 50 to 100 dollars and restores all-day life to a phone that otherwise works fine — versus 800-plus for a new flagship. The exceptions: your phone has stopped receiving security updates, the screen or port is failing too, or an app you rely on no longer supports your model.

When is the best time to buy a new phone?

Right after a new model launches, last year's flagship typically drops 15 to 30 percent and trade-in promotions peak. Buying the one-generation-old model new, or a current model lightly used, is the consistent value play — the year-over-year differences are mostly camera tweaks and a faster chip most people never max out. Avoid upgrading mid-cycle at full price.

Big purchases

Should I upgrade my phone?

Is it worth upgrading my phone now, or should I keep my current one another year?

Flagship phones now cost as much as a laptop, while year-over-year improvements have become incremental. Whether an upgrade is worth it usually comes down to three things: your battery health, your software-update status, and whether anything is actually broken.

Short answer

Upgrade if your phone is running out of security updates, something beyond the battery is genuinely failing, or one purchase would fix several tired parts at once — and even then, last year's model or a refurbished unit is usually the smarter buy. Keep your phone another year if the battery is the only complaint: a replacement restores all-day life for a fraction of a flagship's price, and the year-over-year gains are mostly ones you will never notice.
