Google Pixel 10 Vs. OnePlus 15 has a decisive battery winner: the OnePlus 15. In comparable 2025 testing, it lasted 25 hours and 13 minutes against 13 hours and 13 minutes for the Pixel 10, while its 80W charging reached 81% in 30 minutes. The Pixel costs less, but it cannot match the OnePlus for endurance or charging speed.
Which phone has better battery life?
The OnePlus 15 has substantially better battery life than the Google Pixel 10. Tom’s Guide recorded 25 hours and 13 minutes for the OnePlus 15 and 13 hours and 13 minutes for the Pixel 10 in its comparable 2025 cellular web-surfing tests, giving the OnePlus a 12-hour advantage.
Battery life is the operating time a phone delivers between full charges under a defined pattern of use. The testing conditions matter because screen brightness, cellular signal strength, gaming, navigation and camera use can change the result.
A concrete calculation shows the size of the difference. The OnePlus result was about 91% longer than the Pixel result in Tom’s Guide’s 2025 testing: 12 additional hours divided by the Pixel’s 13.22-hour runtime. Put another way, the OnePlus ran for roughly 1.9 times as long.
Future Labs testing published by TechRadar told much the same story in 2025. The OnePlus lasted almost 22 hours, while the Pixel reached 13 hours and 15 minutes. TechRadar’s September 2026 best-phone guide still reported the OnePlus result at almost 22 hours, more than one hour beyond the best iPhone or Samsung Galaxy model tested by the lab.

| Tom’s Guide web test | 13 hr 13 min | 25 hr 13 min | OnePlus: 12 hr longer |
| Future Labs test | 13 hr 15 min | About 22 hr | OnePlus: about 8 hr 45 min longer |
| Charge after 30 minutes | 52% | 81% | OnePlus: 29 percentage points higher |
| U.S. wired charging | Approximately 30W | 80W | OnePlus: up to 50W higher |
Why does the OnePlus 15 last longer than the Pixel 10?
The OnePlus 15 carries a 7,300mAh battery, compared with the Google Pixel 10’s 4,970mAh battery, according to their 2025 manufacturer specifications. The 2,330mAh difference gives the OnePlus approximately 47% more nominal capacity, although capacity alone does not determine real operating time.
The laboratory gap is even larger than the capacity gap. Tom’s Guide measured approximately 91% more runtime from the OnePlus in 2025, indicating that power management, display behavior, the processor and software optimization contributed alongside the larger cell.
Battery capacity isn’t a direct promise of screen time. Two phones can consume energy at different rates, and a weak mobile signal can drain either one faster. Still, a 7,300mAh cell provides a large reserve that software efficiency alone is unlikely to erase.
There’s one overlooked consequence: a long-lasting phone can reduce partial charging during the day. Fewer emergency top-ups are convenient, but no supplied evidence establishes that the OnePlus battery will retain a particular percentage of capacity after a set number of charge cycles. Buyers concerned about long-term health should avoid assuming that greater capacity automatically means a longer service life.
How long do the Pixel 10 and OnePlus 15 last in daily use?
The Google Pixel 10 generally provides about one day of ordinary use, while published 2025 reviews put the OnePlus 15 at more than two days under mixed use. Tom’s Guide logged 2 days, 11 hours and 5 minutes from the OnePlus without power-saving mode; TechRadar reported nearly three days.
Those mixed-use reports aren’t controlled head-to-head tests, so you shouldn’t treat 2 days, 11 hours and 5 minutes as a guaranteed result. Your screen brightness, signal quality and time spent recording video can shorten it. Even so, independent laboratory and daily-use results point in the same direction.
Android Authority’s staff obtained approximately five hours of screen-on time from the regular Pixel in 2025. Google’s own 2025 specification claimed more than 24 hours of normal use and up to 100 hours with Extreme Battery Saver, but manufacturer estimates and independent continuous-use tests answer different questions.
OnePlus claimed up to 31 hours of video playback for its flagship in 2025. That figure is useful within the company’s stated scenario, not as a substitute for mixed-use or cellular browsing tests. Honestly, the larger model makes the most sense if you travel, use hotspot service or routinely finish the day near empty.
Software can also alter consumption after launch. Owners following Google’s platform changes can review the September 2026 Android update changes, though no recent update in the supplied research produced a new authoritative battery test for this matchup.
Which phone charges faster?
The OnePlus 15 charges faster than the Google Pixel 10 by both wired rating and measured 30-minute progress. Tom’s Guide reported in 2025 that the OnePlus reached 81% after 30 minutes with 80W U.S. charging, while the approximately 30W Pixel reached 52% in the same period.
A 29-percentage-point lead after half an hour is meaningful because the OnePlus is filling a much larger battery. Based on nominal capacity, 81% of 7,300mAh represents about 5,913mAh, while 52% of 4,970mAh represents about 2,584mAh. Those 2025 calculations are simplified because charging losses and voltage curves prevent battery percentage from mapping perfectly to delivered energy.
Wireless charging is another clear separation. The OnePlus supports up to 50W proprietary wireless charging, while the Pixel supports 15W Qi2 wireless charging, according to the 2025 specifications cited by Tom’s Guide. The Pixel’s Qi2 support may appeal if you value the broader magnetic accessory standard; reaching the OnePlus maximum requires compatible proprietary equipment.
Check the complete charging setup before buying. These are the practical details that change your result:
- Use a compatible 80W charger to pursue the OnePlus 15’s 2025 U.S. wired rating.
- Use compatible proprietary hardware for the OnePlus model’s 50W wireless maximum.
- Use a suitable Qi2 charger for the Pixel 10’s 15W wireless rating.
- Expect both phones to slow charging as their batteries fill or become warm.
Is the OnePlus 15 worth paying more for battery life?
The OnePlus 15 is worth its higher launch price when battery endurance and rapid charging are purchase priorities. It launched in North America at $899.99 for 12GB of RAM and 256GB of storage in 2025, while the Google Pixel 10 entered U.S. stores at $799, a difference of $100.99.
That premium bought 12 additional hours in Tom’s Guide’s 2025 web test. Dividing the $100.99 launch-price difference by those 12 hours produces a rough cost of $8.42 per additional tested hour. It’s not a universal value metric, but it makes the trade-off unusually clear.
The Pixel remains the less expensive purchase. If you can charge nightly and normally finish a day without anxiety, paying more solely for battery life may be unnecessary. Shoppers whose budgets matter more than flagship endurance should also compare new and refurbished budget phones in 2026.
For battery-focused buyers, though, the extra $100.99 at their 2025 launch prices is easy to defend. You receive much longer tested runtime, faster wired charging and a higher wireless charging ceiling. Wider platform differences still matter, so the broader Android 17 and iOS 27 feature comparison can help if your decision extends beyond these two Android phones.
Google Pixel 10 Vs. OnePlus 15 battery FAQ
Can the Pixel 10 last a full day?
The Google Pixel 10 generally lasts roughly one day under ordinary use, based on 2025 reviewer findings. Android Authority reported approximately five hours of screen-on time in mixed use, while demanding camera, navigation or cellular activity can reduce daily endurance.
Does the OnePlus 15 have a two-day battery?
The OnePlus 15 can exceed two days in mixed use, although results depend on workload. Tom’s Guide recorded 2 days, 11 hours and 5 minutes in 2025 without power-saving mode, and TechRadar reported nearly three days in its 2025 review.
Does Extreme Battery Saver make the Pixel 10 competitive?
Google claimed up to 100 hours for the Pixel 10 with Extreme Battery Saver in 2025, but that restricted operating mode is not comparable with a normal-use laboratory test. The claim doesn’t overturn the OnePlus 15’s large advantage in independent testing.
Are manufacturer battery claims directly comparable?
Manufacturer battery claims are not directly comparable unless the test conditions match. Google’s 2025 claim of more than 24 hours for the Pixel 10 and OnePlus’s 2025 claim of up to 31 hours of video playback use different scenarios, so independent tests provide the fairer comparison.
