To make it short: The software works extremely well - with minimal loss of comfort, it is quite feasible to double the battery life. My Galaxy S4 is now running 4-5 days (no, that's not a typo) before it thirsts for new power. Before the app there were a maximum of 40 hours before it came overnight to the power supply (and this I had from the default settings already at least all obvious already optimized).
After installation, you should take the time (1-2 hours in my case) and to click through the various settings. The (only available online and in English) manual pages here are very beneficial. German software or help pages is the way for me no reason for devaluation, rather the opposite, because English texts have the undeniable advantage that they are usually plagued by mistranslations.
As now this software works? The principle is quite simple. When the phone is in standby mode, and the screen is off, the app turns everything from possible, starting with the connections for WLAN and mobile data, via Bluetooth, to the permanent synchronization of different apps. The app can also generally manage GPS, but a gerootetes system requires that I not wanted to do this to me necessarily (at least not as long as guarantee on the phone is).
The settings are varied, so you can adjust Bluetooth, for example so that it is turned on with the switch on the screen and disables after 5 minutes if no known device is found. Find a place with a known coupling device, Bluetooth is switched on permanently. Here is an example of the loss of comfort already mentioned to find, because you need to connect to the phone such as a handsfree in your car to turn on the screen (can it also directly switch off again).
All mobile connections As mentioned in switched off Phone interrupted and prevented the other apps on Synchronize. In regular (adjustable) intervals the app then activates the connection for a short time, so you will be notified about incoming e-mails yet. This is also separately for day and night mode - what can be called * profit even as comfort *, because you will be awakened no longer at night by incoming SPAM :).
All in all it took me immensely personally surprised how big the savings potential of Android phones actually is ... or put the other way around, how much potential Google leaves unused. I personally recommend this app uneingeschänkt anyone who has ever been troubled by the poor battery life of its smartphones. Who will stop at the price, it may indeed initially have a go with the free version, which already has immense potential and quite clearly points to the advantages of the paid version.
