Two Day Battery Life?

Inside the Xperia Z3 is an 11.78 Wh (three,100 mAh at three.8 V) not-removable battery, which Sony claims on their website is adept for ii days of bombardment life. And so, to exam that merits, I pledged to but plug in the Xperia Z3 to a wall charger in one case every two days throughout the period of the review. To my surprise, the handset held up pretty well with this penalisation that would make other smartphones weep.

During my time using the Xperia Z3 equally my daily driver, and only charging information technology once every 2d day, the device never died before day ii was over. This is with my typical smartphone use that includes reading websites, sending emails, social networking, messaging, photography, calls and more than each day. Most phones require a accuse every night, just the Xperia Z3 seems to be an exception.

In the above three benchmarks, the Xperia Z3 boasts battery performance that's relatively the same every bit the Xperia Z2. With like hardware and a slightly smaller battery, this isn't also surprising to see.

Information technology'south with these benchmarks, the well-nigh of import in our suite, that the Xperia Z3 sees significant gains. This is cheers to new brandish management engineering that only refreshes the screen when the content on information technology changes. When displaying static imagery, like when you're reading a webpage or viewing photos, the Xperia Z3 conserves its juice and provides improve battery functioning than its competitors.

You might think that the refresh technology is merely useful for some circumstances, merely throughout your day-to-mean solar day usage of a smartphone there are many cases where content on the screen is not changing. Even if these cases are but a fraction of a 2nd long, not refreshing the display continuously improves bombardment life, as tin can be seen both in these benchmarks and in my full general usage of the handset.

However, the engineering science is not advantageous at all when the screen needs to constantly refresh, like in a game or when you're watching a video. This is why in that location is not a significant battery life comeback in the commencement gear up of benchmarks.

The Z3 also comes with several battery saving features that tin be enabled to extend its life. There'southward Stamina mode, which extends life past turning off connectivity features when the display is off. Yous also get location-based Wi-Fi, a standard low bombardment mode that disables some functions when the battery dips below a certain level, and Ultra Stamina mode. The latter disables nearly every characteristic of the phone, restricting information technology to basic functionality like the ultra power saving modes of the Z3'south competitors.
