The battery is one of the biggest (literally) advantages of ZenFone 6. The capacity is 5000 mAh, which is why charging the battery takes over 2.5 hours – and with an 18 watt charger! Half an hour gives slightly above 30%, and a half will appear after the first hour. We cannot bend the rules of physics, but the long charging time is fully compensated with lifespans. Two days of an intensive work? Not a problem!
With a normal usage three days of work is a norm, and if the phone is used seldom – four days will be normal. Placed aside and working only in the standby mode, ZenFone 6 achieved six days. Battery results are pleasing – especially that we are talking about a smartphone with a top specification. If it only had wireless charging, I would have drown in ecstasy.
Asus ZenFone 6 can please us when it comes to the sound as well. It has two speakers that play loud and clear, but are they stereo?
I have a feeling that the receiver plays a bit quieter than the lower one, and in addition – it transmits lot less lower tones… Still – we can listen to it without disgust, and the power of the smartphone proves to be enough to listen to it in an average room, tent or while camping.
Earphones added to the set are decent as well, though it could have a bit more bass. For those added to the set – they are positive, I will remind that the smartphone has a minijack – so we can connect something better.
In the software we can find Audio Wizard, thanks to which we can enhance the sound using a few predefined settings – or our own, manual sound correction, unfortunately unavailable for the speakers of the phone – we can only use it for external devices, like earphones. In addition, there is the DTS:X device and the Outdoor Mode – that enhances the power of speakers on the expanse of the sound quality.
Asus ZenFone 6 has of course a recorder and an FM radio, which does not have an icon in the tray, we can only find it in the switches panel. The Private Listening is an interesting feature – it automatically switches the sound between the receiver and the speaker, depending on how we hold the phone. Lifting it up to our ear will launch the Private mode…
When it comes to the sound quality during calls, I do not have any major concerns, besides one: the receiver is a bit small and we need to place it exactly on the level of our ear, in order to hear our interlocutor.
Holding the smartphone with our arm will not work when it comes to ZenFone 6. Besides this – the sound is good and it has enough power for a comfortable conversation.
The microphone works great as well. The camera app is enhanced with the possibility to record calls, while the text communication is entrusted to the classical Google keyboard. All communication modules worked appropriately during tests, I will add that there is NFC.
