On Pixel 4 battery, Google’s various teams don’t see pixel-to-pixel

Despite all its machine learning prowess, Google doesn’t learn.

Look at my Google Pixel phone reviews, from the original in 2016 and the Pixel 2 in 2017 to the Pixel 3 XL and the latest Pixel 4 XL: You’ll notice the constant pain point in every review has been battery life. How is this a hard problem to solve?

Almost every Android manufacturer has been outfitting flagship phones — and even budget devices — with large battery cells upward of 4,000mAh to keep them powered for a full day and a little more. This year, we’ve seen Huawei’s P30 Pro last more than a full day easily, and Samsung’s Galaxy S10 Plus manages to get to the end of a day with relative ease. It makes sense to prioritize improving battery life as countless surveys show how U.S. adults are spending more time on a mobile device than watching TV.

Even Apple has joined the club. The company went so far as to make its latest iPhone 11 Pro and iPhone 11 Pro Max thicker than predecessors to fit beefier batteries, and the results are glorious — phones that can still have 20% remaining at midnight after a heavy day of use.

The Pixel 4 and Pixel 4 XL, with their respective 2,800mAh and 3,700mAh batteries? Not so much. I frequently hit 30% around 5:30 p.m. with medium to heavy use, and the phone itself would often claim that it would die around 10 p.m. based on my average usage. I felt as though I needed to turn on battery-saver mode toward the latter half of most days to ensure the phone would last. Sure, I can wirelessly charge it during the day or carry a portable battery charging pack, but what if I’m not near a desk or if I forget my charger? I rely on my phone for work and so when I’m out and about, turning the phone off isn’t a convenient solution either.

The answer, in reality, is simple: Google needs to use bigger batteries in its Pixel phones.

Why hasn’t it yet? It’s unclear, but the design team told me it won’t compromise on battery life just to make the phone thin, and the hardware team said otherwise. Are they pointing fingers at each other?

Wires crossed

Ahead of the Made By Google event on October 15, I interviewed the Pixel 4 designers and got a chance to learn about the process of designing Google’s newest phone. It was fascinating, but I also had to ask whether or not the team had any influence on battery life — perhaps they didn’t want to make Pixel phones too thick?

Max Yoshimoto, director of industrial design at Google, told Digital Trends that Google’s phones are designed to deliver “beyond 9-to-5” battery life and that his team works with the hardware engineers to understand the required power draw for each device.

“We want to really get everybody kind of a full day of use,” Yoshimoto said in a prior interview. “So if it has to be a little thicker, we’ll make that call. Obviously, we don’t want it to be too thick. But once again, we do want to deliver a great experience so we’re not going to compromise that part of it.”

“To maintain a great fit-in-hand, we shrunk the battery slightly from the prior Pixel 3 device.”

Is the baseline 9-to-5 battery life? If so, Pixel phones achieve that as they most certainly require a recharge if you intend to use them after work hours. Should it be the baseline? Absolutely not. People use their phones well after they leave work.

I recently asked Google if it has any specific battery claim it provides people looking to buy the Pixel 4, and the company said, “Pixel 4 and Pixel 4 XL’s battery can last through a regular day of use.” That’s not really helpful.

Apple offers up tons more detail here on its product page for the iPhone 11 Pro, listing video playback time (streamed and local playback) as well as battery life for audio playback. Google’s claim is nowhere to be found on its Pixel 4 tech specs page, and there isn’t even a spotlight on the battery in its main splash page talking about all the Pixel 4’s features. Contrast this to Apple’s splash page, where you’ll see a dedicated section talking about the improvements to the iPhone’s battery.


Here’s the rub: The Pixel 4, a $799 smartphone, has a smaller battery than the Pixel 3 as well as the Pixel 3a, a $399 phone. Considering all the new technology inside the Pixel 4, from a 90Hz screen to radar-sensing tech, who thought that was a good idea? I asked Google why the battery capacity dropped.

“To maintain a great fit-in-hand, we shrunk the battery slightly from the prior Pixel 3 device,” a spokesperson told Digital Trends. “We then leaned more heavily on software to deliver all-day battery, and designed features accordingly.”

Confusing. One team said they reduced the battery capacity for a more comfortable fit in the hand, yet the design team said it wouldn’t compromise on battery life, even if it meant a thicker phone. That must mean all parties think the Pixel 4’s battery life is sufficient, but our testing quite easily shows otherwise (as does our history of reviewing Pixel phones). Google put a little too much faith in its ability to use software optimizations to improve efficiency; that or the hardware team doesn’t fully understand the power requirements for the phone.

And even if you look at “fit-in-hand,” the Pixel 4 is 8.2mm thin; the iPhone 11 Pro is 8.1mm, and has a 3,046mAh cell. Google isn’t even winning points here for being the thinnest.

Look, I really like the Pixel 4 and Pixel 4 XL. They have excellent cameras, slick screens, and helpful software features. All I want is to be able to use this phone — at varying levels of intensity — without having to worry about it dying. I can do that on competitor phones like the iPhone 11 Pro, and if Google’s trying to mimic features from the iPhone like its new Face Unlock system, I hope it’ll take a cue and add bigger batteries in the Pixel 5.

A new Google Pixel Tablet is coming, but it’s not what you think
Google Pixel Tablet on its charging dock.

It's been almost a year since the Google Pixel Tablet went up for preorder, leading many Android tablet fans to wonder when the inevitable Pixel Tablet 2 will arrive. A new rumor suggests that Google could release a new Pixel Tablet as early as next month, but it's probably not what you were expecting or hoping for.

According to @MysteryLupin on X (formerly Twitter), Google is planning to "relaunch" the Pixel Tablet without the charging/speaker dock included in the box. As you'll likely recall, the speaker dock is the Pixel Tablet's standout feature. You can use the Pixel Tablet on its own as a traditional Android tablet when you want, and when you're done, you throw it on the dock to transform it into a smart display. The idea of Google selling the Pixel Tablet without its claim to fame is an interesting one.

5 phones you should buy instead of the Google Pixel 8

The Google Pixel 8 is a well-received Android-based smartphone. However, there are reasons why you might not choose it and opt for something else. Perhaps its 6.2-inch display does not meet your requirements, or its camera system does not match your expectations. It could also be possible that you would prefer a phone released in 2024 instead of one launched late last year.

If you’re not interested in buying the Google Pixel 8, several alternative phones may be more suitable for your needs. For instance, the Samsung Galaxy S24 has the same-sized display as the Pixel 8 but with better internals. Alternatively, you could consider the OnePlus 12R, which offers a bigger display and better internals at a lower price. And that's just scratching the surface.

Whatever you do, don’t buy the Google Pixel 7a right now

Google I/O 2024 is just a month away. We expect Android 15 to be shown off, and some hardware, too. In previous years, Google has used I/O to show off the latest for its Pixel A-series device. This year should give us the Google Pixel 8a, and we might even get a peek at what’s coming with the next-generation Pixel Fold 2.

The Google Pixel 7a launched last May, so it’s almost a year old now. At the time, while the 7a was mostly solid, the higher price made it a bit of an awkward recommendation, considering its specs and close positioning to the higher-end Pixel 7.
