Can I run Gemma 3 4B on Samsung Galaxy S25 Ultra (16GB, 1TB config only)?
Yes. Gemma 3 4B runs on Samsung Galaxy S25 Ultra (16GB, 1TB config only) at Q4_K_M (~3.8 GB of ~12 GB usable).
Runs at Q4_K_M using ~3.8 GB of ~12 GB usable. You have room for FP16 for higher quality.
That figure is at a 4k context and moves about ±15% as context length changes. Samsung Galaxy S25 Ultra (16GB, 1TB config only) leaves ~8.2 GB of headroom, room to step up to FP16 for higher quality.

Which quant fits
Running cost · estimate
- Power draw
- ~8 W
- Electricity / 1M tokens
- ~$0.02
- Pays for itself after
- ~3,373M tok
At ~$0.15/kWh and the estimated ~17 tok/s, a million generated tokens costs about $0.02 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$1,619 Samsung Galaxy S25 Ultra (16GB, 1TB config only) pays for itself after roughly 3,373 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.
How to run it
On Android use PocketPal AI (Polished app, download GGUF and run offline.).

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
