How to Win iQOO City Battles
This is NOT a normal hackathon. 55% of your build time you can ONLY use the phone. Your strategy needs to account for Red Light (phone only) and Green Light (both devices). Here’s how to win.
The Scoring Rubric (Know What Judges Want)
| Criteria | Weight | Source |
|---|---|---|
| End product quality | 30% | Jury |
| Novelty and impact | 20% | Jury |
| Creative phone use (camera, voice, on-device AI) | 15% | HackTracker device data |
| Technical depth | 15% | Jury |
| Office Kit usage | 10% | HackTracker device data |
| Demo and presentation | 10% | Jury |
Key insight: 25% is measured from DEVICE DATA, not your pitch. HackTracker records your actual phone usage. You can’t fake it.
Strategy for Red Light (Phone Only – 55% of time)
- Pre-plan your Red Light work – know exactly what you’ll build during phone-only time
- Use Office Kit for everything – screen mirror, clipboard, files. This IS your bridge and it’s scored.
- Camera + voice in your app – 15% of scoring is creative phone use. Build features that USE the camera, microphone, on-device AI.
- Practice Office Kit before the event – remote control, file transfer, shared clipboard. Be fast.
Strategy for Green Light (Both Devices – 45%)
- Heavy compute during Green Light – complex model training, large builds, dependency installs
- Keep the phone in the loop – even during Green Light, use Office Kit to keep phone connected
- Polish and debug – use Green Light for the tricky integration work
What to Build (Maximum Score)
Build something that:
- Works on the phone (30% – end product quality, demoed on iQOO)
- Uses camera/voice/NPU creatively (15% – device data proves this)
- Has a local/open-source model (earns brownie points per rubric)
- Bridges phone and laptop meaningfully (10% – Office Kit usage)
Preparation Checklist
- Download Office Kit for your laptop (pc.vivoglobal.com)
- Practice screen mirror + remote control workflow
- Research local LLMs that run on Snapdragon NPU
- Plan your app with phone-native features (camera, voice, sensors)
- Pick your track and prepare your idea for screening
