Battery Life

Battery life of the Pixel 4 series was a concern from the very first moment we had confirmation about the phone having a 90Hz panel, yet doing nothing special or even regressing in terms of the battery capacity of the two models. I put the Pixel 4 XL through the paces in all three display modes, testing the battery life at 60Hz, 90Hz auto, and 90Hz forced refresh rates.

Unfortunately, as expected, the results aren’t too fantastic. The device that we should be comparing things to is the OnePlus 7 Pro – both devices feature 1440p 90Hz displays with the same SoC, it’s just that the Pixel 4 XL has a smaller battery at 3700mAh. While the Pixel 4 XL is lagging behind the OP7Pro, the interesting thing is that Google’s 90Hz seemingly uses less of a power hit than OnePlus’ implementation, degrading by 7.7% versus 8.7% when comparing full 90Hz versus 60Hz.

Given the results and the fact that Google dual-sources with LG, I very much doubt the Pixel 4 XL is taking advantage of Samsung’s newest more efficient OLED emitter generation which is said to be 15% more efficient.

In PCMark, the results are also average to bad. 60Hz to full 90Hz incurs a 12.3% penalty, which is again slightly less than the 13.6% of the OnePlus 7 Pro. Naturally we can’t come to a conclusion of saying Google’s 90Hz is more efficient, maybe OnePlus’ 60Hz power management is just better implemented.

Battery Life Conclusion - Average to meagre, still useable for the 4 XL

Overall, the Pixel 4 XL’s battery life isn’t very competitive. It’s amongst the worst results we’ve had for a 2019 device. I have to be accountable to myself here as whilst the phone has worse battery life than the OP7Pro, it’s not that much worse. Having said that the OP7Pro battery life was still completely useable, the Pixel 4 XL is also still very useable as it is. The problem again is that the Pixel came 6 months later, and in the face of a new iPhone generation which brought immense leaps in battery life, the Pixel 4 XL doesn’t seem to be that wise a purchase.

I really find it unfortunate that we weren’t able to test the battery life of the smaller Pixel 4. This model’s 2800mAh battery is 25% smaller and also comes with the wildcard of having an LG panel which historically have always been less power efficient. I can easily imagine that the battery life of that model is outright disastrous, and given coverage by other reviewers, it seem this would be an apt description of the situation.

    I dunno if they're smurfing to not upset their partners or genuinely just don't give enough time and thought to hardware development, but Google perpetually seems stuck in the mode of "maybe next year, they'll get really serious about hardware". I'm starting to believe it'll never happen, apart from the Pixel 2 camera catching everyone by surprise.

    At 100 dollars more than the iPhone 11, this phone is a hard stretch for me, the 90Hz OLED is nice but the battery life is correspondingly worse.

    Nokia, I remember, were kinda out of step with the hardware too.

    Look where they went...

    Nokia leased their name to a bunch of people and capital from Foxconn who now formed HMD. Reply

    HMD is a Finnish company I think, not Chinese?
    They have decent mid range devices, but they just don't launch a top of the line device.

    HMD is formed in Finland, mostly by Chinese or by Finnish working for Foxconn. Reply

    Not sure you can lump the literally $400, and very good, 3A that is often on sale in with the other two there... Reply

    I will never understand how come OnePlus price is double vs Xiaomi Reply

    There are phones with "Nokia" labels on them but Nokia doesn't have anything to do with them other than collecting royalties. Reply
