You would think that the massive 3000mAh battery on the Xperia Z1 would make it last longer than any other 5-inch smartphone out there, but - surprisingly - it does not.
How exactly does the Xperia Z1 compare versus today’s most popular smartphones? We said it ranks last, but it’s the difference in longevity we find particularly striking. The newest devices like the Galaxy Note 3 and LG G2 have nearly 50% higher scores.
What is the reason for such a poor showing for the Xperia Z1? We honestly do not know, but we’d assume two reasons - lack of proper software optimization and higher than average brightness.
All in all, the Sony Xperia Z1 is a bit of a disappointment, as you can see how it gobbles through your battery, especially when you use it for media or browsing. We hope that newer phones like the T-Mobile Z1 version known as the Sony Xperia Z1s or the Z1 Compact will bring some big improvements.
Sony Xperia Z1 battery life test
We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.
As for our battery test, we use a simulation of real-life usage. A smartphone nowadays is used for much more than calling and texting, so we had to take this into account. The average smartphone user actually spends most of the time on the web and social media, and you might be surprised that this average Joe of a user actually listens to music and plays games more than he talks! To get a better understanding of that average use, feel free to take a look at the top activities we do on our smartphones. We replicate this test very strictly with every phone paying attention to minute detail and even keeping the same distance between devices and the wireless router during testing to keep signal strength the same.
