How do I stop my phone from throttling while mining?
You usually cannot stop your phone from throttling completely while mining, and you should not disable its heat protection. Throttling means your phone slows its processor to keep temperatures safe; the best approach is to reduce the mining workload and help heat escape so it can run more steadily.
Turn down the mining workload first
Mining keeps your phone’s CPU—the processor that runs your apps—busy for long periods. Unlike a quick task, it gives the phone little time to cool down. Most phones have no cooling fan, so they cannot hold their top speed indefinitely.
If your browser miner provides controls:
- Lower its CPU usage or intensity. Start at the lowest setting, then increase it slowly.
- Use fewer mining threads. A thread is one stream of work running on the processor. More threads can produce more heat without adding much useful mining speed.
- Take cooling breaks. If the phone still becomes hot at a low setting, stop rather than pushing through.
After each change, let the phone settle for several minutes. Watch its sustained hashrate—the number of mining calculations it completes each second—not just its speed immediately after starting. A lower setting may deliver steadier work than repeated bursts followed by heavy slowing.
Give your phone a cooler setup
Small changes can help your phone shed heat:
- Keep it out of direct sunlight and away from heaters.
- Put it on a hard, open surface, not a bed, cushion, or blanket.
- Remove a thick case if you can do so safely.
- Lower screen brightness.
- Avoid gaming, video calls, navigation, or other demanding tasks while mining.
- Use gentle airflow from a nearby fan if available.
Do not put your phone in a fridge or freezer, or press ice against it. Sudden cooling can cause condensation, which can damage electronics. Never keep mining after a temperature warning.
Avoid adding charging heat
Charging while mining can make throttling worse because both activities generate heat. Fast charging and wireless charging can add even more.
For a short test, try mining while unplugged, with enough battery remaining. Stop before the battery gets low. This is not a recommendation to repeatedly drain and recharge your phone: that adds battery wear too.
If your phone offers a manufacturer-supported charging limit or bypass-charging feature, check its instructions. These features vary by model and do not remove the processor’s heat limits.
Stop immediately if the battery swells, the screen starts lifting, or the phone becomes unusually hot. Do not continue charging a swollen battery; arrange professional service.
Check whether heat is really the cause
A speed drop does not always mean thermal throttling. Your phone may also slow or pause a browser miner when:
- Battery saver is enabled.
- You switch to another app or browser tab.
- The screen locks.
- The browser limits background activity.
If mining pauses only when you leave the page, cooling will not fix that. Avoid installing unofficial “throttle unlockers” or rooting your phone to bypass safety limits. Apps promising guaranteed mining speed can also be scams.
The bottom line
Aim for a cool, modest workload—not maximum speed. Phones are generally poor choices for sustained Monero mining, and battery wear can outweigh any reward. If yours keeps getting hot even at low intensity, the safest solution is to stop mining on it.
