For years, iPhone have allowed 2 active telephone numbers at the same timethat is, Dual Sim, all thanks to the ESIM they have incorporated, that is, there will be no need for two holes in the card tray, as one of them will be virtual.
This depends on the country, since in Asia they have two holes, while in the United States, they only work with electronic. However, whatever, we can all have 2 active lines, which has many advantages, but also some disadvantages.
Problems to use Dual Sim on iPhone
Although, as we said, this has many points in favor, such as receiving work calls and personal, using data from two different companies (which can improve the signal and speed), or register on websites where they request code per SMS with 2 different numbers, also has a very particular disadvantage, and is battery consumption.
While the Esim consumes the same as a physical cardhaving two at the same time, since both will be looking for their own tower to connect, whether from the same company or different, which has an important consumption in the total of our battery.
This is something that we can check with the airplane mode, since if we put it, an iPhone can last 3 or 4 days without going out, however, if we leave it with a signal, in 1 day you will have lost almost the entire percentage, although we do not even touch it, due to this.
Therefore, if we use 2 lines at the same time, although one of them we have it as an emergency and we barely use it, the battery degradation will be very high, and this can be a problem, especially if we need to have them.
Now, what happens if it is a secondary line, which does not receive important calls and we only have it for certain moments? In this case we can do something to, without having to remove it, reduce that extra consumption.
We will have to go to the Settings> Mobile data> Select the SIM> Deactivate the “Activate this line” section.
In this way we would do something similar to putting it in a plane mode, but only the secondary line or that we do not want to use at that time, automatically changing the data and calls to the main one, so we would not lose the connection or have to readjust this every time we change SIM, but we would get one of them not to be looking for coverage at all times.
In summary, it is a good way to avoid this battery drop if we do not need to have both active at the same time, something that not everyone knows, and that many wonder why they are so fast now now, when they do not realize that it is for this reason.
And you, do you use a 2 cards? Leave us a comment with your opinion and experience, and if you really notice when you have the active data, and when you put it in plane mode or deactivate a sim, the truth is that it does notice, and much.
