Can you mine Monero on an Android phone?

Yes, genuinely. Monero's RandomX algorithm was designed to resist ASICs, so ordinary CPUs are its intended hardware — and a modern phone's big cores are real CPUs. With Primo ARM Miner you install a free APK (or run one Termux command) and mine at roughly 700 H/s on a modern 8-core phone, no root required. It's hobby scale, not income, but it's real mining on the real network.

How much Monero can a phone actually mine?

A little — think cents per day at current difficulty and price, before electricity. ~700 H/s is a tiny slice of the Monero network, so this is for spare hardware, learning, and supporting the network, not for income. Anyone promising more from a phone is selling something.

Do you need root to mine Monero on Android?

No. Both paths work on a stock, unrooted phone: the Primo APK runs as a normal sideloaded app with a foreground service, and Termux is a regular app from F-Droid. Root only helps with one thing — escaping Android's background-app throttling — and there are no-root workarounds for that (keep the screen on, or mine from an SSH/adb shell).

Why does RandomX need so much RAM, and what if my phone doesn't have it?

RandomX is memory-hard by design — full-speed fast mode builds a ~2.1 GiB dataset. If your phone can't spare that much free RAM the miner automatically falls back to light mode, which uses a 256 MiB cache instead and runs about 5× slower (~160 H/s). The app picks the mode for you; nothing to configure.

Is mining Monero on a phone safe for the device?

RandomX is the hottest-running algorithm this miner supports, so the phone will get warm and Android will cap the clocks if it gets too hot — it won't cook the device, but sustained heat is the main wear factor. Mine plugged in, keep the battery cool (a small fan helps a lot), and don't run 24/7 on a phone you rely on.

GUIDE · MONERO ON ANDROID

Mining Monero on Android has never been easier

Not long ago, mining Monero on a phone meant installing a compiler toolchain in a terminal and building XMRig on-device — an hour of downloads that often failed halfway. Now it's a free APK you tap through in two minutes, or one Termux command. Same real RandomX, same real network. Here's both paths — and the honest numbers most guides leave out.

1 · Why a phone can mine Monero at all

Monero is the one major coin where a CPU is the intended mining hardware. Its RandomX algorithm was built to resist ASICs and GPUs, so the network is hashed by ordinary processors — and a modern phone's big cores are ordinary processors, the same ARM designs that power laptops and servers. You won't out-mine a desktop Ryzen, but you're not fighting datacenter silicon the way you would on Bitcoin. That's what makes phone mining on Monero legitimate rather than a gimmick. (If you want the fastest coin for a phone specifically, that's Verus — but Monero is the classic.)

2 · The easy path: the app

Download the Primo ARM Miner APK from the downloads section and sideload it. No root needed — the screenshot walkthrough covers every tap, including the Play Protect "unknown developer" notice.
Configuration → Algorithm → randomx. Pool URL stratum+tcp://pool.supportxmr.com:3333, wallet = your XMR address, password = a worker name. Threads and fast/light mode are picked automatically.
SAVE, then START MINING. The dashboard reads 0.00 for the first ~15 seconds — that's the RandomX dataset build, not a problem.

3 · The terminal path: one Termux command

Prefer a terminal? Install Termux (from F-Droid, not Google Play), then:

termux

$ curl -fsSL https://primolab.dev/install.sh | sh
$ primo-arm-miner -a randomx -o stratum+tcp://pool.supportxmr.com:3333 \
      -u YOUR_XMR_ADDRESS -p worker1

The installer downloads a prebuilt ARM64 binary and verifies its SHA-256 — no compiling, no toolchain. The full Termux guide (including the screen-off throttling fix) is here.

4 · Wallet and pool, briefly

Use the official Monero wallet (getmonero.org) or Feather, not an exchange address. pool.supportxmr.com:3333 is a solid default pool (or port 443 with stratum+ssl:// for TLS). For a slow worker like a phone, a fixed-difficulty suffix — YOUR_WALLET+50000 — makes shares arrive at a steadier rate. Full pool details are on the Monero page.

5 · The RAM thing (fast mode vs light mode)

RandomX is memory-hard by design. Full-speed fast mode builds a ~2.1 GiB dataset — fine on a phone with 6–8 GB of RAM, and worth ~700 H/s on a modern 8-core. If free RAM is short, the miner automatically drops to light mode: a 256 MiB cache instead, about 5× slower (~160 H/s), but it runs on almost anything. The app decides for you; in Termux you can force light mode with PRIMO_RANDOMX_LIGHT=1.

RandomX is also the hottest-running algorithm here — mine plugged in, watch the temperature tile, and give the phone airflow. A small fan genuinely helps.

6 · Keeping full speed

Android throttles apps that aren't front-and-center: backgrounded apps get fewer cores and capped clocks. The APK handles this by running as a foreground service and keeping the screen on while mining. In Termux, run termux-wake-lock first, or — the full-speed trick — mine from an SSH or adb shell, which stays unthrottled even with the screen off. Details in the Termux guide.

7 · What you'll actually earn

Cents per day, at best. ~700 H/s is a real contribution to the network but a tiny slice of it. If a video or app promises meaningful phone-mining income, it's lying to you — usually to sell something. We'd rather tell you now.

What you actually get: real XMR accumulating on a pool from hardware that was in a drawer, a working understanding of how mining fits together, and a phone that's doing something more interesting than depreciating. That's the honest pitch — free hardware and learning, not income. The miner takes a 1% dev fee on RandomX (60 s per 100 min, logged in the console).
