Is it safe to mine Monero while my phone is plugged in?

You can mine Monero while your phone is plugged in, but it is not a good idea for long, unattended sessions. Mining and charging both produce heat, and that extra heat can wear out your battery faster or make your phone stop charging to protect itself.

Why being plugged in changes the risk

Mining makes your phone’s processor do repeated calculations to help secure the Monero network. That work uses electricity and creates heat. Charging your battery creates more heat, especially during fast charging.

Connecting a charger does not automatically mean your battery is resting. Your phone controls how power reaches its parts and battery. Depending on the model, charger, and workload, it may charge more slowly, pause charging, or even lose battery charge while plugged in.

Some phones offer bypass charging, which can power the phone without actively charging its battery. If your phone supports it, check the manufacturer’s instructions. It may reduce battery-related heat, but it does not remove the heat produced by mining.

What can happen to your phone

The most likely problem is faster battery aging, rather than an immediate failure. Keeping a battery hot, especially while it stays near full charge, can gradually reduce how much energy it holds.

Your phone may also:

• Slow its processor to cool down. This is called thermal throttling, and it reduces mining performance.
• Dim its screen, pause charging, or show a temperature warning.
• Become uncomfortable to hold or shut down.

Built-in protections help, but they are not a reason to leave mining running overnight. A damaged battery, faulty charger, or trapped heat can make the situation more dangerous.

If you try it, keep it brief and supervised

Treat phone mining as a small experiment, not a round-the-clock job.

• Start with the lowest workload. If the miner lets you limit processor use, keep it low.
• Stay nearby. Check the phone regularly and stop if it keeps getting hotter.
• Use a hard, open surface. Never mine while charging under a pillow, on bedding, inside a bag, or in direct sunlight.
• Use a compatible, reliable charger and cable. Avoid damaged cables and questionable adapters.
• Avoid stacking heavy tasks. Gaming, video calls, and navigation can add more heat.
• Use charging limits if available. A manufacturer-provided battery protection setting can reduce time spent fully charged, though it does not make continuous mining harmless.

There is no single safe temperature number for every phone. Follow your model’s guidance rather than relying on how warm the case feels.

Stop mining and unplug the charger if you see a temperature warning or notice unusual heat. If the battery swells, the screen lifts, or you notice an unusual smell, stop using and charging the phone and arrange professional service. Do not try to cool it in a fridge or freezer.

The bottom line

Brief, low-power mining while plugged in may be manageable on a healthy phone with good ventilation, but continuous charging-and-mining is not worth treating as risk-free. Browser mining still uses your processor and produces heat. Phone earnings are usually tiny, so protecting your battery is likely more valuable than keeping the miner running.
