Google and Sony released their respective flagships back in October of last year. And although the Pixel is currently more popular than the Xperia XZ, the latter is an underrated and powerful device and is the best mobile phone Sony has ever made thus far. Read on to determine which flagship offers better overall performance battery-wise.

Google Pixel – Battery specs and features

The Pixel sports a 2,770 mAh non-removable lithium-ion battery. It delivers up to 110 hours of music playback, up to 26 hours of 3G phone calls or 19 days of standby time. The Google flagship only lasts a whole day of normal usage, which means it needs to be charged nightly.

The Google Pixel is suspect when it comes to intensive gaming, but it seems to do just fine with everything else. Thankfully, the handset reaches 100 percent in just a little over an hour of charging. One premium feature that the Pixel noticeably lacks, though, is wireless charging.

Sony Xperia XZ – Battery specs and features

The Sony Xperia XZ, on the other hand, packs a slightly powerful 2,900 mAh non-removable lithium-ion cell. That kind of battery muscle is sufficient for a device with a 5.2-inch screen. The handset can put up with over 17 hours of 3G talk time or about 25 days of standby time.

The Sony handset makes use of the X series standard Qnovo adaptive charging. The technology moderates battery damage and extends the cell’s lifecycle. While the Xperia XZ isn’t capable of being wirelessly charged just like the Pixel, it makes up for it with its Quick Charge 3.0 feature.

Google Pixel vs Sony Xperia XZ: Battery performance test

During TechRadar’s battery performance test, the Google Pixel performed slightly better than the Sony Xperia XZ. Both flagships went through a series of battery-draining tasks that included an hour and a half each of web browsing, YouTube playback, gaming and native video playback.

Following the web browsing test, the Pixel had 65 percent remaining battery life while the Xperia XZ had 68 percent. But the Sony handset struggled during the YouTube test and only had 38 percent after playback was finished. The Google Pixel, meanwhile, soared with its 43 percent battery life.

When the gaming test was done, the Xperia XZ had three percent cell power while the Google smartphone had 4 percent. The Xperia XZ ended up with a total performance time of four hours and 41 minutes. The Pixel lasted three minutes longer with its total of four hours and 44 minutes.
