Motorola phones are frequently purchased for value, which can make replacement more appealing when repair quotes climb. Using 2.5 years as a conservative average lifespan baseline (per a Statista-cited summary) helps keep decisions realistic: if the phone is already near typical upgrade age, large repairs may not be a good investment.
Repairs under the threshold often make sense for high-impact items like a battery or screen replacement, especially when the device otherwise runs smoothly and has adequate storage. Replacement becomes the safer choice if the phone has water-damage symptoms, unstable charging consistent with board issues, or repeated crashes that suggest deeper hardware faults.
Also consider software and security support; if updates are limited, repairing may extend hardware life without extending safe usability. The replacement price benchmark uses Apple's published iPhone 15 starting price as a mid-market reference; many Motorola models cost less new, so treat this threshold as conservative and err on the side of replacement when multiple repairs are needed.
