The Sony Xperia Z comes with a 2,330mAh capacity battery. This may sound a lot compared to the typical 1500mAh batteries in previous Xperia phones, but the Xperia Z has a larger 5-inch display to power, all in 1080p, as well as a quad-core chipset. GSM Arena recently put the Sony Xperia Z through their battery lab tests to reveal some respectable results.
Sony’s Stamina mode goes some way in keeping the phone lasting throughout the day, but if you want to know how much talk time, video playback and web browsing time you can expect from the phone then check out the charts below. The handset managed just over 16 hours of 3G talk time, 5 hours and 39 minutes of video playback and 6 hours and 37 minutes of web browsing. Overall standby time was 48 hours (not including Stamina mode), which seems a decent result.
