The "Bufala" of the code * 3370 #
Every month compare a new amount of false information, which on occasions like this, cannot harm anyone and in other cases can compromise your security and your information or personal data.
This 'hoax' or false rumor that runs and spreads more and more among users, it is not even new, it is one of those rumors that come back periodically, taking advantage of the curiosity of several Android users, has found a way to bear.
The way to spread this false information against users is, of course, through the web, social networks, especially WhatsApp, different users will have fallen into the offer of 50% more extra battery.
Is it possible to have 50% more battery life?
Obviously, by entering a secret code on your device, as if it were a cheat for Android devices, it is totally false, when you enter this code in the phone app on our mobile device, absolutely nothing happens.
“Has your cell phone battery run out? All mobile phones have a power reserve in their batteries which when you dial * 3370 # are activated automatically, giving you up to 50% additional charge. "
This is the rare message spread on social networks and also on WhatsApp, where it is promoted that, by using the code * 3370 # we will be able to get additional battery, fortunately nothing happens after entering the code.
Other times, could cause irreversible damage to our mobile devices, if we are not careful about the instructions we follow on the apps, the instructions that reach us through the web, etc.
By applying logic we can identify many of these hoaxes, for example, having 50% more battery only when entering a code on the device keyboard, it is unreasonable to even consider it true, especially since we are talking about the part of mobile phone devices that have evolved less in recent years.
The safest thing is having this feature manufacturers would not leave it as a hidden feature (like their hidden games did) and would have a factory activated, i.e. would have the feature activated by default.
Can I save the battery?
The best thing you can do is learn to have a conscious use of our battery, so you will see a saving in the daily battery consumption of your device, this without enough information can be complicated.
Apps consume more and more battery, more RAM, i.e. they are increasingly demanding for devices, battery saving is of vital importance, battery saving mode on both PC and battery saving on Android devices has been positioned as a primary function among electronic equipment .
