iOS 9 prevents the screen from turning on when receiving notifications, the Apple company designing this system to reduce the energy consumed by our terminals in daily use. The new system intelligently detects if an iPhone terminal or an iPad tablet is placed in a pocket/backpack or is placed with the screen down, blocking the screen from turning on to display notifications.
The initiative of those from Apple is called Do less work, the statement referring to the internal components of iDevices, which have less "work" in the moments when we do not use our terminals.
In this idea, if you keep an iPhone in your pocket for a long time, then until you take it in your hand you will not see the notifications received from your applications, iOS 9 taking care not to consume a lot of energy to display them.
Apple's idea is great because users don't see the screen lit anyway when their terminal is in their pocket or in a bag, or when it is placed with the screen down on a surface, so playing a sound is the only way to alert necessary.
To make this detection, the company uses the accelerometer, the gyroscope and the ambient light sensor of the iPhone terminals, so information is taken from multiple sources and everything should work extremely well for us.
Apart from this extremely great functionality, the Apple company has also implemented new ways to reduce the "awakening" of the processors, so that they will run at the minimum frequency most of the time.
Dynamically and implicitly increasing the frequency of energy consumption will only be done when it is really needed, but of course Apple does not reveal much information about this.
Having said that, iOS 9 is meant to seriously improve battery life, but we told you today that, unfortunately, iOS 9 battery life it is very bad in the first beta version.
