It takes about as much time to mine 1 Bitcoin on a phone as it does on a computer. The main difference is in the amount of electricity that is used.
On a phone, you are typically only using the battery, which means that there is much less of a carbon footprint.
Mining Bitcoin on a phone is not recommended, as it can be difficult and time consuming. Mining Bitcoin requires powerful hardware and a substantial investment of electricity, both of which are difficult to come by when using a phone. Additionally, phones are not designed to handle the intensive calculations required for mining, so attempting to do so could damage your device or significantly reduce its battery life.
Thus, it is strongly advised that you do not attempt to mine Bitcoin on your phone.
The other main difference is that you are not able to do much else with your phone while you are mining. This means that you will have to give up your social media, gaming, and other activities that keep you occupied.
In conclusion, it takes about the same amount of time to mine 1 Bitcoin on a phone as it does on a computer. The main differences are in the amount of electricity used and the ability to do other things with your phone while mining.
