How does the battery usage statistics in iOS 8

One of the innovations of iOS 8 is the ability to keep track of which applications are using the battery. This feature is in Settings → General → Statistics → Battery use.

It is obvious that those applications that spend the greatest amount of battery that is not right, right? And here and there. There are several reasons that an application can consume the battery, and we'll talk about them later.

The use of the battery, there are two tabs: one to monitor applications for 24 hours, the second - 7 days. Applications that spend the greatest amount of charge can do so by 4 reasons:

1. You too often use the app (Twitter, reading, messengers)
2. The application remains active in the background.
3. Weak signal or other technical difficulties.
4. Problems in the application itself.

The first reason is very standard and there is nothing to worry about. You sat there for several hours on Twitter, then be prepared for the fact that the application is going to eat a significant portion of the battery.

The second reason - a consequence of any activity. For example, you want to Dropbox unloaded made photos in the cloud in the background. So long as he unloaded them, it will have a battery. Tweetbot or will load tweets in the background, the consequences will be the same. Customize your applications in the background may be in Settings → General → Content Updates. Be sure to check this tab, there may be a lot of unnecessary applications.

The third reason not depend much on you. Due to the weak cellular signal, antenna devices need more energy for the connection. In addition to the cellular signal is weak may also have WiFi and GPS. And if the first in this case, almost no impact on the battery, the weak GPS can eat all the charge right before our eyes.

Finally, the fourth cause of most unpleasant. For example, you can see that in the first place by the charge flow is worth a Skype, but just remember that you are running it for 5 minutes. In this case, the problem is already in the application and you should either shut it down or restart your device.

And most importantly, do not panic ahead of time. If you have an additional 80% charge, and you see that YouTube ate 50%, which means that he spent only 10% of the battery.
