Crypto mining on a phone: does it work?
Can you mine crypto on a phone? Technically yes, practically no: a phone is millions of times slower than an industrial miner, so the coins it could mine are worth less than the battery it wears out. That is why app stores ban real on-device mining and most "mining apps" are reward apps in disguise. Here is the math, what mining apps actually do, and how to try mining on a phone without harming it.
The math of phone mining
A modern phone computes a few million SHA-256 hashes per second. A Bitcoin ASIC computes around 200 trillion. The whole Bitcoin network does about a zettahash, a 1 followed by 21 zeros, every second. A phone's share of that is so small that it would take far longer than a human lifetime to find a single block, and even pooled mining would pay fractions of a cent per year. Coins designed for CPUs, such as Monero, are more phone-friendly, but still earn less than the electricity and battery wear cost.
You can compare devices in the mining calculator, and see how mining works in what is crypto mining.
What "mining apps" really do
| Kind of app | What happens |
|---|---|
| "Tap to mine" token apps | No real mining; you collect points that may or may not become a token |
| Cloud mining apps | You rent hashrate on someone's farm; frequent scams, see cloud mining |
| Reward apps called "miners" | Pay small amounts from ads and tasks |
| Real CPU miners | Mine for real but earn almost nothing and heat the phone |
| Mining games | Simulate mining as gameplay, sometimes with small real rewards |
App store rules
Google Play and the App Store do not allow apps that mine cryptocurrency on the device itself. Apps that manage mining elsewhere, such as remote dashboards or cloud services, are allowed. So a store app that promises to "mine Bitcoin with your phone" is either not mining or not playing by the rules.
Hidden miners and fake apps
Malware sometimes mines crypto on infected phones for the attacker. Signs: the phone gets hot and drains the battery while idle, apps run slowly, data usage jumps. Avoid APK files from unknown sites, check app permissions, and remove apps you do not recognise. A fake "mining app" may also ask for a deposit to "upgrade your miner": that money will not come back.
Android vs iPhone
On Android, you can technically sideload a CPU miner, but it will heat the phone and earn almost nothing. On iPhone, background limits make continuous mining impossible for normal apps. Either way, real profit is out of reach.
Mining as a game
If you want to see mining work on your phone, a game is the honest way. In TotalHash, a free game inside Telegram, your phone computes real SHA-256 hashes while the game is open and closes blocks of the game network, which pay the in-game token #TH. Real rewards come from tasks and short ads: small amounts of USD₮ and GRAM withdrawable to your own TON wallet from 0.1 GRAM or 1 USD₮. No install, no deposit, and your phone stops mining when you close the game.
Mine blocks on your phone inside Telegram, for free.

Can you mine Bitcoin on a phone?
Technically yes, but a phone is millions of times slower than an ASIC miner, so it would earn less than the electricity and battery wear cost.
Are crypto mining apps real?
Most are reward apps, tap-to-earn token apps or cloud mining services. App stores do not allow apps that mine on the device.
Is mobile mining bad for my phone?
Continuous mining heats the phone and wears the battery. Hidden miners in malware do the same without your consent.
What is the safest way to try phone mining?
A mining game that runs only while open and needs no deposit, such as TotalHash in Telegram.
