Endurance
LG has pulled out several techniques to extend the battery life. They have succeeded reasonably well. For example, the frame rate is screwed down or up if necessary. The same goes for clocking (processor) and timing (operating system). This combination is called '3 Adaptive Optimalization'. Fortunately, as a user, you don't notice much of it, except that the battery lasts for more than a day. Even with very intensive use, we still managed to get the end of the day by 20%.

There is an energy saving mode available that you can automatically switch on from 50, 30, 20 or 10%. Once turned on, things like synchronization, WiFi, Bluetooth, the vibration function, screen brightness and screen time-out can be turned off. You can choose what to turn off and what not. In the end, we didn't need this mode at all, so we can't say much about how it works. This is a compliment because it means that the LG G3 will last a long time.
Call quality
We had no problems with call quality during our test week. Conversations are crystal clear and we also received no complaints from our interlocutors. There is still an option to turn on voice enhancement while calling, but we could not notice a really clear difference. And maybe that's a good thing too. Finally, the sound can be turned really loud, so be careful.

The interface to dial a number looks familiar and simple. Also the overview of the call history is more than fine. It is possible to set up a filter so that you only get missed calls.
