The iQOO 15 is the stronger fit on listed chipset, screen resolution, battery capacity, and rear-camera hardware. The Motorola Signature is slimmer and lighter, supports a display refresh rate up to 165Hz, lists a 1TB storage option, and carries Motorola’s stated commitment of up to seven years of OS upgrades and security patches. In India, the prices cited here are snapshots rather than a guaranteed like-for-like deal: iQOO’s official store showed ₹85,999 for its 12GB+256GB model, while 91mobiles displayed ₹62,899 for the Motorola Signature.

Which phone has the better performance?
On the named processor specifications, iQOO 15 has the higher-tier platform: Snapdragon 8 Elite Gen 5 versus Snapdragon 8 Gen 5 in the Motorola Signature. That distinction does not establish how much faster either phone is in real use, or which will sustain performance better during extended gaming. The cited specifications do not provide matched tests, so choose based on the chipset tier only if that is a priority; look for comparable independent testing to judge sustained speed, thermals, and gaming.

The iQOO 15 lists a 6.85-inch AMOLED panel at 3168 × 1440, compared with the Motorola Signature’s 6.8-inch AMOLED at 2780 × 1264. iQOO therefore prioritizes higher pixel resolution. Motorola lists a maximum refresh rate of 165Hz, which may appeal to buyers who value a high refresh-rate specification. These figures alone do not establish brightness, color accuracy, or the experience in particular apps and games.

How do the cameras compare?
iQOO lists three 50MP rear cameras: a main camera, an ultra-wide, and a 3× periscope camera. Its listed front camera is 32MP. The Motorola Signature is listed with 50MP rear cameras, while 91mobiles reports a 50MP front camera. The hardware gives iQOO a clearly specified periscope option and Motorola a higher listed front-camera resolution; neither fact proves which phone takes better photos or videos. Megapixel counts do not substitute for matched camera samples, stabilization details, or testing across lighting conditions.
Battery capacity and charging differences
The iQOO 15 lists a 7,000mAh battery and 100W wired charging; Motorola lists a 5,200mAh silicon-carbon battery and 90W wired charging. Motorola lists faster wireless charging at 50W, versus 40W for iQOO. These are manufacturer-listed capacities and charging rates, not measured endurance or charging-time results. Capacity alone cannot establish which handset lasts longer: screen settings, workload, network conditions, and software all affect runtime.

Which phone is thinner and lighter?
Motorola lists the Signature at 162.1 × 76.4 × 6.99mm, and comparison sources list its weight at about 186g. iQOO lists thickness of about 8.14–8.28mm depending on finish and weight around 216–221g. On these listed figures, Motorola is the slimmer and lighter choice. Confirm the exact finish and regional variant when comparing a specific retail unit, since iQOO’s figures vary by finish and the weight figures come from comparison sources.

Software support: the clearest long-term distinction
Motorola Support India states that the Motorola Signature receives “Up to 7 years” of OS upgrades and security patches. The iQOO product page consulted lists OriginOS 6 based on Android 16 but does not provide a comparable support-duration claim. That absence is not proof that iQOO will provide no updates; it means the available product information does not establish an equivalent term. Buyers who prioritize a stated long-term update commitment have a documented figure for Motorola to consider.

India price difference and what the listings mean
The official iQOO India E-Store displayed ₹85,999 for the iQOO 15 with 12GB RAM and 256GB storage; it showed an MRP of ₹92,999. Separately, 91mobiles displayed Amazon-labeled price snapshots of ₹85,999 for iQOO 15 and ₹62,899 for Motorola Signature. On those comparison-page figures, the Motorola listing is ₹23,100 lower than the iQOO listing. This is not a verified like-for-like offer comparison: the iQOO store figure is for a specified configuration, and the cited Motorola figure is a third-party retailer snapshot, not an official Motorola price. Bank offers, exchange values, sales, stock, and configuration can change the amount payable. Check the live listing and exact variant before buying.

Which one should you choose?
- Choose iQOO 15 if you prioritize the higher-tier named chipset, a sharper listed display, greater battery capacity, or a 3× periscope rear camera.
- Choose Motorola Signature if you prioritize a slimmer, lighter build, a display specified up to 165Hz, a listed 1TB storage option, a higher-resolution listed front camera, or Motorola’s stated update commitment.
- Compare independent reviews before deciding if your choice depends on actual gaming performance, camera quality, or battery endurance; specification listings do not settle those questions.
