Xiaomi phones are popular globally for strong specs at aggressive prices, which often makes replacement more appealing once repair costs rise. Using a conservative 2.5-year average smartphone lifespan baseline (from a Statista-cited summary), repairs under the threshold are typically worthwhile when they fix high-impact issues like a battery swap, screen replacement, or charging port repair-especially if the phone remains stable and still receives security updates.
Replacement becomes the more conservative choice when multiple expensive modules fail together (screen plus camera), or when there are signs of water damage or board-level faults such as intermittent charging, random reboots, or no-power conditions. Also consider total ownership value: if a repair doesn't meaningfully extend secure, reliable use, replacement often wins.
The replacement price benchmark uses Apple's published iPhone 15 starting price as a mid-market reference; many Xiaomi models cost less new, so this threshold intentionally discourages over-investing in repairs on older devices.
