Between the iQOO 13 and Phone (3a), the iQOO 13 comes out ahead in antutu and wired charging, while the Phone (3a) wins on weight. Overall, the iQOO 13 scores 75.3 and the Phone (3a) scores 62.5 on our Mars Score.
Which should you buy?
The iQOO 13 is the clear pick on raw spec strength, leading by 12.8 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the iQOO 13 if you push the hardware — gaming, on-device AI, heavy multitasking — and the extra compute headroom is worth the trade-offs. The biggest gaps in its favor are antutu, wired charging, ram, among others.
Pick the Phone (3a) if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight.
Both ship with comparable main camera, 5g support, front camera, so those specs don't separate the two — focus on the differences below.
Bottom line: the iQOO 13 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
