When should I replace my phone?
Replace a phone when reliability, security support, repair cost or daily limitations outweigh the value of keeping it—not simply because a new model exists.

Short answer
Replace your phone when it can no longer do essential jobs reliably, no longer receives needed security updates, or costs more to repair than its remaining value. A weak battery alone may be cheaper to replace than the whole phone.
Why
- Security-update support matters for banking, work and personal data.
- Battery, display and port repairs can extend useful life when the rest of the device still meets your needs.
- Storage pressure, poor cellular compatibility or repeated crashes can become practical replacement triggers.
Important conditions
- Physical battery swelling or severe overheating requires immediate service, not a wait-and-see upgrade decision.
- A phone used for critical work may justify replacement earlier than a secondary device.
- Trade-in value and repairability vary by model, condition and market.
What to do
- Check update status, battery health, storage and repair quotes.
- Compare repair cost with a suitable replacement—not only the newest flagship.
- Back up, sign out and securely erase the old phone before trade-in or recycling.
