How much XMR can a smartphone mine per day?
A smartphone will usually mine only a tiny fraction of an XMR per day, and mining in a web browser may earn so little that you never reach the service’s payout minimum. There is no reliable fixed daily amount: your result depends on your phone’s sustained mining speed, the Monero network’s mining activity, and any fees.
How to estimate your daily XMR
Your phone earns a share of the mining rewards based on its share of the total mining work. Mining speed is called hashrate, measured in hashes per second, or H/s. A hash is one attempt at doing the calculation needed to help secure the network.
Monero produces a block roughly every two minutes. Its ongoing reward is 0.6 XMR per block, which works out to about 432 XMR per day across the whole network, before transaction fees.
A simple estimate is:
Daily XMR ≈ (your phone’s H/s ÷ network H/s) × 432
For example, suppose your phone sustains 100 H/s and the network runs at 5 billion H/s. Those are illustration numbers, not current measurements.
Your estimated share would be:
100 ÷ 5,000,000,000 × 432 = 0.00000864 XMR per day
That assumes uninterrupted mining for 24 hours, before fees. Running for six hours at the same speed would produce about one-quarter as much.
Why your phone’s real output is lower
A short speed test can make your phone look better at mining than it really is. As your phone heats up, it usually slows its processor to protect itself. This is called thermal throttling.
Your daily total also falls when:
- Your browser pauses mining after you switch apps or lock the screen.
- Battery-saving settings limit processing.
- You use fewer processor threads, meaning fewer mining tasks run at once.
- Your connection drops or the mining service stops accepting work.
Monero uses RandomX, a mining method designed to favor general-purpose processors. Its fast mode needs a roughly 2 GB dataset, a large collection of working data. That is demanding for a phone, especially inside a browser. A phone’s advertised processor speed alone cannot tell you its daily XMR output.
Measure earnings, not just a speed counter
For a useful estimate, check your sustained hashrate after the phone warms up, rather than its initial peak. Then use a live Monero mining calculator with that speed and your actual daily running time.
Check what the browser service is measuring, too. A displayed speed does not necessarily mean your phone is doing native Monero mining. Some services perform other work and convert the proceeds into XMR.
Look for:
- Clearly stated fees and reward calculations.
- A minimum withdrawal amount.
- A record of accepted work and credited XMR.
A credited balance is not the same as money you can withdraw. Divide the payout minimum by your estimated daily earnings to see how long withdrawal might take.
The bottom line
Treat smartphone mining as a small experiment, not dependable income. Your likely XMR output is tiny, while heat, battery wear, and electricity are real costs. Stop if your phone gets unusually hot, and be wary of services promising large daily returns or asking you to pay to unlock withdrawals.
