Google Pixel 3 vs Pixel 3 XL: battery life

Google Pixel 3 vs Pixel 3 XL: battery life
The new Google Pixel 3 and Pixel 3 XL are the product of a seamless integration between hardware and software, a showcase of how fast and smooth an Android phone can be, plus they feature two of the best phone cameras out there.

How about battery life though? The smaller Pixel 3 features a 2,915 mAh battery and comes with a 5.5" OLED, 2280 x 1080-pixel screen, while the larger Pixel 3 XL sports a larger, 3,430 mAh battery, but also has a 6.3" OLED screen with a more taxing resolution of 1440 x 2960 pixels.

In an age of growing battery sizes, these batteries are actually smaller than what the competition offers, so you might be worried whether they are good enough.

That's where our proprietary battery test comes to help: we now have the Pixel 3 and Pixel 3 XL battery life results and you can compare them to other phones below:

Battery life (hours) Higher is better
Google Pixel 3 8h 22 min (Excellent)
Google Pixel 3 XL 7h 39 min (Good)
Google Pixel 2 8h 40 min (Excellent)
Google Pixel 2 XL 8h 57 min (Excellent)
Apple iPhone XS 8h 37 min (Excellent)
Apple iPhone XS Max 9h 34 min (Excellent)
Samsung Galaxy Note 9 8h 56 min (Excellent)
Samsung Galaxy S9+ 8h 5 min (Excellent)
OnePlus 6 8h 10 min (Excellent)
LG V40 ThinQ 6h 21 min (Average)

Interestingly, the new Pixels both score lower than last year's models in our test, but what's even more interesting is that the larger 3 XL model has a lower score than the Google Pixel 3. This is strange because the larger Pixel has a bigger battery, but what comes into play here also is the higher resolution and bigger power draw from the larger screen that obviously takes more power.

And in comparison to the rest of 2018 flagships, the Pixel 3 series are also slightly below the average.

Charging time (minutes) Lower is better
Google Pixel 3 113
Google Pixel 3 XL 123
Google Pixel 2 111
Google Pixel 2 XL 152
Apple iPhone XS 185
Apple iPhone XS Max 209
Samsung Galaxy Note 9 109
Samsung Galaxy S9+ 105
OnePlus 6 80
LG V40 ThinQ 109

There are no surprises when it comes to the time it takes to charge up these phones from 0 to 100%. Both come with fast, 18-watt chargers in the box and both wall chargers support the new Power Delivery fast-charging standard.

The Pixel 3 and 3 XL both take around two hours to fully charge, with the XL being slightly slower due to the larger battery cell.

Are you surprised by these results? And are they good enough for you? Let us know in the comments right below.

This in deed interesting. In your test do you go from 100 to zero percent. iPhone historically starts off well but then depletes rapidly once under a certain percent (false representation when first off the chatger?). Not saying that the XS Max has bad battery life, it is excellent, just wondering if you were taking batteries down to zero or performing a calculation based on percentage of use after a few test.

Oh, I hope the XL has better battery life than what you have stated, but I have heard that the battery drains rapidly while "sleep", so a fix may be required.

So, yes, we account for that. We do a full run from 100 to until the phone is dead and it's true what you are saying that historically the iPhone battery percentage seems to go down faster towards the end of the test. One thing that we do that many others do not (especially YouTubers that are often quoted in the comments section), is that we set the brightness of the screens on all the phones at 200 nits, to ensure that the results are actually comparable because if there is even the slightest difference in brightness levels, you could get a big delta in the end results. And for many phones, we double and triple-run the test to ensure the results are correct and reliable. Over at the page with all of our benchmarks, you can read the full description of the battery test that we do: "We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness."

Victor H. Really? "We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness." First of all running any web-script is not designed to replicate the power consumption of a typical real life usage. That is complete BS. Second of all running a web-script on both Android and iOS will not run the same on both platforms. Third, since it's just a web-script (text files). How about posting the web-script so everyone can see what is actually running for your test, and how it is running. Especially since this is NOT replicating real life power consumption.

The fact you just run a web-script explains why your battery tests are so woefully inaccurate and the Phonebuff test that used a robotic finger and tries to simulate actual daily usage showed that the iPhone Xs battery life wasn't anywhere as good as your test claims.

Well, you can pick the one test that endorses your phone and call it a day, but then if you look at other YouTubers' tests, then why not mention the last test by Mrwhosetheboss where the iPhone wins? Look, I am not defending the iPhone, I don't care and I actually prefer using an Android phone these days, but battery life depends on too many variables. What I am saying is that the script that we are running is fine-tuned to stress the phone in a way that is similar to real-world use. And in creating it, we are emulating exactly that: 1 hour of social, 1 hour of gaming and so on. The script is designed so that it mimics typical phone use. So yes, you could look at different tests and see different results, but as far as our test goes, it's been the same reliable and proven method that we have run on all smartphones in the last three or four years, so you get really truly comparable results and you can see how a phone from 2018 compares to a phone in 2015. Naturally, this is impossible to replicate by using a combination of apps that constantly get updated and changed, so this is the one big advantage of using a script that is carefully fine-tuned to reflect real-world performance. Is it perfect? No, but it produces consistent reliable results that we think are indicative enough of real-world performance.

The results are what they are but for some reason you're putting the label "consistent and reliable" on it. You could put that label on any standardized test and each standard could give you wildly different results.

Yes. A battery test should be broken down into various things. Video playback Web browsing Taking photos Messaging Gaming These are the five things that nearly everyone will do on their phone on a near-daily basis. This should also be repeated at maximum brightness, a fixed brightness, minimum brightness and at auto brightness.

This just confirms my suspicion that LG really doesn't give a damn about battery life.

Where did Lg come in it ?

He's referring to the LG V40 ThinQ coming in last place in battery life.
