Sometimes, when we are in the mountains, at a sporting event with a lot of people, etc., we have little coverage, which is not only a problem for getting an internet network, but also for our battery, which degrades much sooner due to it.
This is due to something very simple, but that not everyone knows, because they believe that, without coverage, the iPhone should spend even less batterysince it is not sending or receiving anything, but it is not, although we can fix it.
How to prevent the iPhone from draining battery when it has no signal
First of all, we are going to see the reasons why this happens, since, as we said, logically, we think that it is precisely the other way around, and not having internet should not generate consumption, however, it is due to the following:
- The phone modem works at maximum power: the chip that is responsible for mobile communications (2G, 3G, 4G, 5G) increases the energy it uses to try to “reach” any nearby antenna.
- Repeated network scans– Every few seconds or minutes, the phone does an “active search” for signal towers, which consumes quite a bit of power.
- Switching between networks– If there is a weak or intermittent signal, the iPhone may be jumping between different bands or technologies (for example, between 4G and 3G), which also drains more battery.
- Additional processes– Some iOS apps and services try to recover connection for updates, notifications, emails, etc., and this generates even more activity.
For all this, not having a signal could imply a very high battery consumption, leaving us without it in a few hours, which is a problem, especially if we are waiting for the connection to return, as happened to us in the blackout, however, it can also happen on a mountain, or inside a cave or town where we know there is none, and then we can avoid it in a simple way.
How to avoid excessive consumption? It is very easy, to do this we will only have to activate airplane mode, thus preventing it from searching for new signals, moving between them, and sending the necessary information to the apps that there is no connection, so that they do not try to synchronize anything for now.
We can deactivate, occasionally, from time to time (about 20 minutes), the airplane mode, thus being able to check if the signal is already stable and functional, or if it is still going around trying to get it. If so, we can activate this mode again, or leave it already removed, being able to navigate again with normal energy consumption.
And you, did you know the reasons why An iPhone that does not have coverage uses more battery What one that does have? Now you know it, and the method to maintain, during the time that you know you are not going to have the network, the maximum possible battery. We could also turn it off, but logically it is more tedious and we would not be able to use apps like Maps with GPS that would work just as downloaded, for example, as well as play something if we are bored and we already have it installed on the phone.
