Sony Xperia XZ Premium Features: Battery Care & Qnovo Adaptive Charging
Delivering a decent battery life is one of the biggest challenges for modern smartphones. We remain ever-connected and demanding of constant high-quality content, yet also expect devices to last a full working day.
Finding common ground between these two extremes is very difficult! Thankfully the Sony Xperia XZ Premium continues a strong Sony tradition of delivering on battery life. To do this, it utilises a few features, some always active and others you can tinker with.
There are also reports made available at all times. This lets you monitor battery performance and the expected range of the current charge. At the end of the day this is a premium smartphone and you should have access to as much information as possible about its performance.
QNOVO Charging & Battery Care
Modern lithium battery technology degrades over time. It’s inevitable and even with care, cells used every day will hold less charge after several months’ life. To make the most efficient and safe system of recharging possible, Sony have implemented Qnovo Adaptive Charging.
The full details of Qnovo are highly technical. If you’re interested, you can read the white paper below.
To put everything in basic terms, software algorithms are used to more carefully charge the cell. Rather than simply putting as much current through the cell as possible, there is a constant feedback loop as the system scans the cell and adapts to what is reported.
The result is that fast charging can still be achieved while hastening the damage done to the physical cell. The system is also much safer than traditional charging, as it can recognise and adapt to spikes in heat that could indicate a dangerous situation.
Branded as Battery Care in the XZ Premium software, Qnovo also monitors your battery while it is discharging. It checks battery temperature and pressure at all times, adjusting workload if it reaches extremes.
The same is also true if the battery capacity reaches the 10% & 90% extremes during charge and dsicharge – changing power consumption to avoid damage often caused to Li-ion cells.
This is the name given to Sony battery management suite. The most immediately useful screen is one that predicts your power levels. From here, the XZ Premium will accurately estimate how long your current charge will last. This is calculated based on your average usage at certain times of the day.
If the system thinks you will run out of power before you usually charge, then it will warn you. It will then prompt you to activate the manual STAMINA mode.
STAMINA mode reduces energy consumption. You can tweak the settings to make it very conservative (no data use, kill all background apps etc.), or just trim the edges of you power consumption (reducing brightness etc.) There are three preset power-saving levels which you can adjust.
Quick Charger UCH12W
In the box for the Sony Xperia XZ Premium you will find the UCH12W quick charger. This official Sony accessory will allow you to charge the phone as fast as possible.
