Sony Xperia XZ3 Dual SIM


It definitely makes an impression


I had no major reasons to complain about the battery in the Xperia XZ2 model. Maybe it did not have an incredible performance, but it could last for a whole day with an intensive usage. And with a more toned down – even longer. When it comes to the XZ3 model it is similar. Here are measurements in different scenarios:

  • lifespan with the display on (YouTube, 1 SIM card, active Wi-Fi module, 50% screen brightness) - 8 hours and 42 minutes,
  • an hour of video streaming (Chrome, 1 SIM card, active Wi-Fi module, 50% screen brightness) - 11% of battery lost,
  • an hour of playing videos from the phone’s memory (airplane mode, 50% of brightness) - 8% of battery lost,
  • half an hour of using online navigation - 8%,
  • half an hour playing Real Racing 3 - 12%,
  • PC Mark battery test results – I did not manage to finish the test – at the end of benchmark the app shut down,
  • 8 hours in the standby mode - 3%.

While lifespans are acceptable, the charging time – using the charger from the set – is far from what a flagship should represent. Sony has placed in the set the EP800 charger, which parameters are 5V – 850 mAh. The cell has 3300 mAh, so it takes a lot of time to charge it – not only when we consider modern standards, but how fast flagships should be charged as well. After 15 minutes we only have several percent, after 30 minutes – less than 20%. After an hour the charge level shows 35%, after two – 71%. As you can see, fully charging the batter takes a few hours – around 3.5. Though of course we can use a faster charger.

I will add that Sony uses Qnovo Adaptive Charging technology – it is supposed to ensure a prolonged life of the cell by monitoring charging parameters. However, for most users how quick we can charge the battery in a short period of time is much more important. Xperia XZ3 can, in a longer perspective, offer a better efficiency, but in an everyday usage – it does not astonish. I will add that there is a wireless charging possibility (Qi standard).


Sony Xperia XZ3 has a lot of advantages, though it is a smartphone that costs 799 euro – and it has a strong competition. For such a price we can buy flagship models from Huawei and Samsung, and maybe even iPhone from the last year. What does it stand out with? Mainly with an attractive looks, perfect OLED display, great sound quality (both from speakers and through Bluetooth) – in other words, Sony has made an almost perfect multimedia smartphone. Why almost? Mainly due to the lack of a minijack. In addition it has the newest Google system, interesting housing colours (for example Forest Green and Bordeaux Red) and a high efficiency, for which Snapdragon 845 is responsible. Our enthusiasm is lowered by average lifespans, slow charger in the set, not entirely ergonomic placement of elements on the housing and photos, which gives way to the competition when it comes to the quality.
