After the light blackout in Spain, many people have seen how their iPhone, without coverageI lost a lot of battery, something that worried them, because they also had no way of loading it, at any time the data and telephony network returned.
This is due to something very simple, but 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 so, although we can solve it.
How to prevent the iPhone from spending battery when it has no signal
In the first place, we are going to see the causes for which this occurs, since, as we said, logically, we think 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) rises the energy it uses to try to “reach” any nearby antenna.
- Repeated network scans: Every few seconds or minutes, the phone makes an “active search” of signal towers, which consumes enough energy.
- Change between networks: If there is a weak or intermittent signal, the iPhone can be jumping between different bands or technologies (for example, between 4g and 3g), which also wears more battery.
- Additional processes: Some apps and iOS services try to recover connection for updates, notifications, emails, etc., and that generates even more activity.
For all this, not having a signal could imply a very high battery consumption, leaving us in a few hours without it, which is a problem, especially if we are waiting for the connection to return, as has happened to us in the blackout, however, it can also happen in a mountain, or inside a cave or town where we know that there is no, and then we can avoid it in a simple way.
How to avoid excessive consumption? It is very easy, for this we must only activate the airplane mode, preventing it from being looking for new signs, moving between them, and sending the necessary information to the apps that there is no connection, that they do not try to synchronize anything for now.
We can deactivate, in a timely manner, from time to time (like 20 minutes), the airplane mode, thus being able to check if the signal is already stable and functional, or if it continues to go around trying. If so, we can re -activate this mode, or leave it already removed, being able to sail with a habitual consumption of energy.
And you, did you know the reasons why An iPhone that has no coverage spends more battery What do you have? Now you know, and the method to maintain, during the time you know you are not going to have a network, the maximum possible battery. We could also turn it off, but logically it is more tedious and we could not use apps such as maps with GPS that would work the same, for example, as well as playing something if we are bored and we have already installed it already on the phone.
