How to extend the battery of our device is the war of every day. Our iPad and, above all, our iPhone, have a limited autonomy, less than we would like, and you have surely read countless sites that promise extra hours of autonomy following advice of all kinds. At MacWorld they have tried Nine of the most popular tips to see which are fact and which are fiction. We tell you.
Calibrate the battery: something true
Apple recommends that we calibrate the battery of our devices from time to time. This process consists of letting the battery drain completely and then fully charging it. Although it is a recommended process, it serves above all to take care of your battery in the long term and so that the estimation of the remaining battery that the system makes is reliable, but in reality, does not increase the autonomy of your device directly.
High brightness means a higher expense: very true
The screen brightness is one of the aspects that most influences battery life, and not only in a few minutes, but in hours of duration. Setting the screen brightness to half can lead to a battery life of your iPad that is twice as long as it would if it were at full brightness. Such a simple detail can prevent your iPhone from leaving you lying in the middle of the afternoon without being able to use it, so keep that in mind.
Sharing Library from iTunes drains your battery: very true
Watching a movie that is stored on your device involves a much lower battery consumption than you would if the movie is stored in iTunes and you watch it via streaming using the "Share at home" option. In the test, the iPad lasted 5 hours 34 minutes playing video stored on the iPad, an hour longer than when it played via streaming.
Doing AirPlay drains your battery quickly: false
Unlike what happens when we stream from a computer to our device, do AirPlay from our device to Apple TV does not consume excessive battery consumption. In the test, the iPad sent HD video to Apple TV for 13 hours 45 minutes and still had 82% of the duration left.
Turning off the equalizer during playback increases the duration: false
Contrary to what Apple itself and other applications say, turn off the equalizer while music is playing does not improve the battery life of your device at all. In the tests carried out, the battery consumption after several hours with the playback activated with and without the equalizer was practically identical.
Specialized apps improve your device's battery: false
There are dozens of applications on the App Store that promise to increase the battery life of your device. In the test, three of the best known were analyzed: Battery Doctor, BatterySense and Sys Activity Manager Lite, and the reality is that by themselves they do nothing to increase your battery life. They can give you useful information about battery life, or tips to take care of it, but nothing more.
An external battery increases battery life: very true
Well ... there is little to say about this, right? Obviously, getting an external battery, either in the form of a case for the iPhone, or in the form of a "flask" for the iPad, will help you have more autonomy. And obviously, the higher the capacity of the external battery, the more autonomy it gives you.
Location and Maps suppose a high cost of battery: very true
Next to the shine, another of the functions that drain the battery of your device. Any application that makes intensive use of GPS (TomTom, Maps, Google Maps ...) will drain your iPhone's battery in about 4 hours, a little more on the iPad. Do not forget to close the application completely once it has been discontinued to avoid unpleasant surprises.
Airplane mode increases battery life: very true
It is also obvious that if we turn off all the radios of our device (WiFi, Bluetooth, GPS, data, 3G) the battery will last longer. It can be useful to use this mode when we are about to watch a movie and we do not want to be disturbed during that time, in the test they got 30 more minutes of playback in airplane mode on an iPhone 5.
