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.

    Custom ROMs are a thing, do your research before to get a phone that is well supported and you can have unlimited* software support. I can get an Android 9.0 ROM for my Moto G 2013.
    And if you buy the right phone, something like a Pocophone from last year or a Xiaomi Mi 9 variant now, you can get a top of the line specced phone (S855, 6 GB RAM, 64+ GB ROM, 1080+ AMOLED, 48 MP tripple cameras etc.) for half the price of the entry level iPhone 11, get good custom ROM support and even decent normal support for a year or two and if you don't anymore, you can buy the newest thing from them and have paid less than one iPhone for 2 phones in the end. You can even get their entry level phone with a slower SoC and if you don't game you won't notice the performance difference in Facebook or Youtube, and then get 3 phones for the price of one iPhone.

    I'll take 3 years of support on my OnePlus device for roughly 1/2 to 2/3 of what an equivalent-spec iPhone would have cost. The battery's already tired after that length of time, and even if you keep your iPhone a year or two longer I'm still winning on cost.

    Well, what?
    Google only released latest security patches along with updates to all their pixel phones on 5th of nov and does this each month.
    It's a rarity that some OEM pushes those before google does, essential only does simultaneously.
    And when other's do, they still get 1st of each month .

    The Galaxy S7 I am typing this with received 2 full OS upgrades, and is running the Aug 1 2019 k installed in Sept). It has received security updates every other month for the past year, so I'm expecting the next one in the next or so.

    My wife's Galaxy A8 (2018) has already received an OS upgrade and gets security updates every other month as well. We've had it for just over a year now.

    Our old Galaxy S6 received OS upgrades, and the last security update it received was for late 2018.

    IOW, Samsung update process has greatly improved the past few years. You get 2 full OS upgrades and at least 3 years of security updates.

    Um, OnePlus?

    For me, the real choices haven't changed much since the beginning. Samsung, LG or Nexus 4/5/HTC Desire/OnePlus. Either the latest flagship, or a decent Google-only device. Not a cheap plastic mid-tier phone (unless that cheap phone is also a Nexus5-type phone with at least flagship CPU.) Pixel 4 should be $400 total.. So should be 50% off.

    You missed OnePlus in your final assessment. They don't do much to the OS, and I've found the small things they do very useful. They don't do Qi either, but their Dash charge and superior battery life serve the same practical function.

    I consider them to be an ideal replacement for the Nexus line that Google ditched.

    Back in May of this year I bought a pixel 3a just to give it a try and I so enjoy the experience I sold my iPhone 8 plus and waited for the pixel 4 to come out and I've been watching reviews and I have to say up kind of disappointed in this phone. Recent review I watched was YouTuber by jerry-rig which tested the durability of the pixel for it failed miserably cracks in 4 areas...yeah I know I know I'm going to stick it in the case but you know it's a back pocket and you sit down in your car forget to take it out take it out after you sit down and madewell cause a problem but after watching that review I don't think I'm buying a mix before going to keep my pixel 3 a.... In the battery was the first thing I thought what a disaster

    Underwhelming, but some of the feature decisions can be explained. 64GB base storage encourages people to make more use of cloud alternatives so Alphabet has greater access to perform analytics on user uploaded information. It's hard to pilfer information from over someone's cellular data plan without that catching attention and motivating the IT security types to go poking around at what you're doing. Encouraging users to put information out there of their own free will means analytics will attract a lot less attention.

    Face unlock is downright alarming stuff that would do Eric Schmidt's decade-old walk right up to the creepy line (his own words back when he was the CEO of Google) expected justice. All that sensor equipment can capture a significant amount of data and put facial analysis of other photographs from other sources into a more useful context. Alphabet is leaning forward here and I would expect the mothership's repository of highly personal data to increase somewhat from this and the addition of Fitbit biometrics collection -- but it's all beneficial to society so it's okay, right?

    As for RAM, I don't see a significant disadvantage in only including 6GB. I rarely see utilization go beyond 900MB on my current phone. Maybe being a bit behind on OS versions has something to do with it though. The only problem here is that Google is offering less memory and less storage for a similar price after showing up late to the party.
