Google is betting that a smarter chip, not a larger battery, will finally solve the Pixel's persistent power drain problem. The upcoming Pixel 11 series, set to launch on August 12, is expected to include a Tensor G6 processor with a significant hardware change: a switch from Samsung's Exynos modem to MediaTek's M90 modem. This swap directly addresses what independent testing has identified as a core weakness in recent Pixel phones.

Why Did the Pixel 10 Battery Disappoint?

The Pixel 10, released last year, introduced an unexpected step backward in battery reliability compared to its predecessor. Android Authority's testing found that the Pixel 10 performed worse than the Pixel 9 during demanding tasks like video calls and camera use, even though it improved in lighter activities like web browsing and video playback. The inconsistency revealed a pattern worth understanding: the phone drained power faster in weak cellular coverage and experienced gaming power spikes that hadn't appeared in the previous generation.

This wasn't a one-time stumble. The Pixel line has a documented history of battery struggles. The Pixel 3, 4, and 6 all faced endurance issues, with the Pixel 4 becoming particularly notorious for poor battery life even in its larger XL model. The Pixel 8 and 9 largely resolved these problems, only for the Pixel 10 to reintroduce the inconsistency.

What's Actually Causing the Power Drain?

The root causes appear identifiable rather than mysterious. Low cellular signal drives up power consumption as the phone works harder to maintain a connection, and gaming can trigger unexpected power spikes on the Pixel 10 Pro XL that weren't present on the Pixel 9 generation. This pattern is roughly the inverse of what a newer, more efficient chip should deliver. A more efficient processor ought to help most under heavy load, where power draw is highest, not under light load where there's little strain to begin with.

The distinction between different types of battery testing matters here. Android Authority ran two separate kinds of tests on the Pixel 10. Its standard battery-test suite measured video calls, content capture, browsing, and playback across the whole series. Separately, the outlet ran low-level power-drain tests specifically on the Pixel 10 Pro XL against Samsung's Galaxy S25 Ultra, and that's where the weak-signal drain and gaming power spikes turned up. One test shows the phone underperforming; the other reveals why.

How Will Google Fix Battery Life Without Bigger Cells?

• Modem Efficiency: The MediaTek M90 modem is expected to handle poor cellular coverage more efficiently than the Samsung Exynos modem used in the Pixel 10, attacking the weak-signal problem at its source rather than masking it with a larger battery.
• CPU Architecture: The Tensor G6 is rumored to include new Arm C1 CPU cores in a 1+4+2 configuration, which could shift power draw in ways that improve efficiency under demanding workloads.
• GPU and Image Processing: The chip is expected to feature a new PowerVR GPU, an updated TPU (tensor processing unit), and a new custom image signal processor, any of which could reduce power consumption during gaming and camera use.

Leaked battery capacity figures suggest Google isn't trying to solve Pixel 11 battery life by simply making the cell bigger. The reported minimum-rated capacities are 4,840mAh for the base Pixel 11, 4,707mAh for the Pro, 5,000mAh for the Pro XL, and 4,658mAh for the Pixel 11 Pro Fold. Even reading these leaks generously, nothing points to a real jump in battery size.

This approach is consistent with Google's historical strategy. Battery capacity across four generations of Tensor-powered Pixel Pro XL phones, from the Pixel 6 Pro through the Pixel 9 Pro XL, moved only within a narrow band of 5,003mAh to 5,060mAh. Four chip generations, and the cell barely budged. Instead, Google has consistently tried to buy more runtime through chip efficiency rather than bigger cells. Battery efficiency, measured as runtime relative to capacity, jumped 35% from the Pixel 6 Pro to the Pixel 7 Pro, stayed roughly flat between the Pixel 7 Pro and Pixel 8 Pro, then rose another 11% from the Pixel 8 Pro to the Pixel 9 Pro XL.

Will the Modem Swap Actually Solve the Problem?

The modem swap is notable because weak cellular signal was specifically flagged as a driver of Pixel 10 power drain in independent testing. A modem that handles poor coverage more efficiently would attack the problem at its source instead of masking it with a bigger cell. Swapping out core silicon suppliers is also unusual for Google, a point worth noting directly, as it doesn't happen super often.

However, recent history counsels some caution before assuming the modem swap fixes everything. The Tensor G5's move to TSMC's 3nm process was supposed to close the efficiency gap with Apple's and Qualcomm's chips, according to independent testing from the previous year. The results were mixed, suggesting that architectural improvements don't always translate to real-world battery gains as cleanly as marketing suggests.

The real test will come once review units ship. Pixel's battery problems aren't a one-off issue that can be solved with a single hardware change. The pattern of worse performance on video calls and content capture, combined with better performance on browsing and playback, suggests the problem is deeply tied to how the phone manages power across different workloads and network conditions. Two Pixel 10 owners can have very different days depending on how much time they spend on Wi-Fi versus fighting a weak signal.

Buyers aren't asking for novelty or cosmetic features at the Pixel 11 launch. They want the specific failure modes documented on the Pixel 10, weak signal and sustained gaming, addressed directly. The only way to confirm that happened is to run the same kind of testing again once review units ship and independent reviewers can put the Tensor G6 and its new modem through the same rigorous battery tests that revealed the Pixel 10's weaknesses.
