Mobile FAQ

Does running Gemma 4 drain my battery quickly? +
Running inference is compute-intensive, so yes — expect noticeable battery drain during active use (similar to gaming). For short conversations (a few minutes), the impact is minor. The model doesn't use battery when idle.
Can I run the 26B model on my phone? +
No. The 26B MoE model requires ~15 GB of RAM just for weights. No current phone has enough available memory. The Edge models (E2B, E4B) are specifically designed for mobile — they're smaller, faster, and optimized for on-device inference.
Is the mobile version as smart as the desktop version? +
Edge models are smaller and less capable than the 26B/31B models you'd run on a desktop. They handle basic conversation, translation, and simple Q&A well. For complex reasoning, coding, or long documents, use a desktop with the full-size model.
