ASUS Zenfone 12 Ultra vs Google Pixel 10a

ASUS Zenfone 12 Ultra

A big, bright 6.78-inch 144Hz AMOLED that's very good in practice — but it's FHD+, not the QHD some expect from an 'Ultra'.

• It's a 6.78-inch LTPO AMOLED at 144Hz, HDR10, with 1,600 nits HBM / 2,500 nits peak at 1080x2400 (20:9), with an always-on display — unchanged from the 11 Ultra.
• Peak brightness hits 2,500 nits with a real-hero ~2,200 nits at 20% APL — though minimum brightness is a bit high at almost 6 nits.
• It's an LTPO 1–120Hz panel with a boosted 144Hz refresh mode available during gaming.
• Calling it an 'Ultra' but shipping no QHD screen is a recurring criticism among buyers.

Google Pixel 10a

The 6.3-inch 1080×2424 pOLED with 120Hz refresh is identical in resolution and panel tech to the 9a, but Google bumped peak brightness 11% to 3,000 nits and finally replaced the ancient Gorilla Glass 3 with Gorilla Glass 7i. Reviewers agree it is good rather than great — bright enough for outdoor use, sharp, fast — but the bezels remain noticeably thick by 2026 mid-range standards, and the panel still ships with 120Hz off by default.

• The Gorilla Glass 7i upgrade from the ancient Gorilla Glass 3 might secretly be the best improvement here, bringing the screen's protection and feel closer to the base Pixel 10.
• After two weeks of use I can't see a single scratch on the Pixel 10a's screen — the Gorilla Glass 7i upgrade noticeably improves on the older Gorilla Glass 3.
• The display is fast, responsive, vibrant, and the on-screen fingerprint sensor is in an easy-to-reach spot toward the middle of the phone.
• Display brightness climbs to 3,000 nits at peak, matching the iPhone 17 Pro — readability is excellent even on sunny days outdoors.
• Slimmer bezels than the 9a, but still pretty thick — only a 0.8% increase in screen-to-body ratio, and noticeably thicker than the OnePlus Nord 5 or Honor 400.

ASUS Zenfone 12 Ultra

Snapdragon 8 Elite plus ROG-derived cooling makes this a fast, stable performer with no thermal drama.

• The Snapdragon 8 Elite provides excellent burst performance.
• Paired with up to 16GB RAM and UFS 4.0, load times are fast, app switching is seamless and gaming performance is rock solid.
• The most demanding titles held a steady frame rate with no lag and no overheating, impressive given the slim 8.9mm body.
• It carries thermal controls (limit CPU boost, dim brightness, disable 5G when hot) so you can tune sustained performance outdoors.
• Its gaming result was slightly better than the 11 Ultra despite the overall battery regression.

Google Pixel 10a

Google broke A-series tradition by reusing the Tensor G4 from 2024 instead of pairing the 10a with the current flagship Tensor G5. Real-world performance is fine — Pixel UI is fluid, animations are smooth, light gaming works — but benchmarks confirm what reviewers expected: the 10a is closer to a mid-range chip than a flagship. The 8GB of RAM cap is the bigger long-term concern for a phone that will get updates through 2033.

• Same Tensor G4 chipset as the Pixel 9a, same 8GB of RAM — there are essentially no performance gains this year, which you might notice when switching between many apps.
• The Tensor G4 isn't bad at all for a $500 phone — Pixel animations are smooth, apps open quickly, and the move to an Exynos 5400 modem brings Satellite SOS plus better thermal behavior.
• Even with average gaming sessions like Diablo Immortal at high settings and 60fps, the phone stayed cool to the touch for an hour straight — thermal management is solid.
• Trusted Reviews measured 4,551 Geekbench 6 multi-core, 1,753 single-core, and 2,608 in 3DMark Wild Life with a 91% stress-test stability — solid mid-range numbers for a flagship-tier chipset from a year ago.
• The 10a's 1700–1750 single-core Geekbench score lags the Pixel 10's 2,300+ by a meaningful margin, and multi-core drops to ~4,500 vs ~6,000 — measurable, but rarely felt during everyday browsing.

ASUS Zenfone 12 Ultra

Strong real-world endurance from the 5,500mAh cell with fast 65W charging — though lab testing shows a regression versus the 11 Ultra.

• The 5,500mAh battery delivered an easy 10–11 hours of screen-on time across a mix of socials, YouTube and light gaming.
• 65W wired charging takes it 0–100% in roughly 39–45 minutes, with 15W wireless and 10W reverse wired charging.
• GSMArena's testing showed a regression — the 11 Ultra hit ~17h14m of battery life versus ~14h11m for the 12 Ultra.
• It carries an IP68 rating and a large 5,500mAh cell — strong stamina credentials for the class.
• One tester reported no wireless charging on their unit, though most sources confirm 15W wireless is supported.

Google Pixel 10a

The 5,100 mAh cell is identical to the 9a's — Engadget measured 28 hours in their video rundown (matching last year), and most reviewers report comfortable all-day life with two-day endurance on lighter use. Charging is the bigger story: wired jumps from 23W to 30W (~50% in 30 minutes, full in ~98 minutes), and wireless from 7.5W to 10W. The non-negotiable disappointment is the lack of Pixelsnap magnets — every single reviewer flags it.

• The 10a ran 28 hours in Engadget's video rundown test — exactly where the Pixel 9a landed last year, putting it middle of the pack for 2026 flagships.
• After a heavy workday — off charger at 8am, messaging, snaps, scrolling, evening event — the 10a still had 26% left by midnight. Two-day life is achievable on lighter use.
• Battery life has been OK — the 10a lasts a full day with average use but still requires daily charging, and heavier travel use pushes me to top up in the afternoon.
• The 10a actually outperformed my personal Pixel 10 on raw battery life — and on lighter days I squeezed two full days of use out of a single charge.

ASUS Zenfone 12 Ultra

It undercuts the big flagships on price and is excellent value used — but a thin software commitment and a so-so camera mean stronger options exist if those matter most.

• Although it's an Ultra with Ultra features, the price is significantly lower than a Samsung Galaxy S-series Ultra.
• It's expected to deliver Qualcomm's latest chipset, a large display and a price tag that undercuts a lot of the competition.
• New, the 16GB/512GB model sits around $1,039–$1,099 via import (not officially sold in the US); used units in mint condition go for $750–$850.
• If you're buying new at $1,000+ and cameras or long-term software support matter most, there are stronger options out there right now.
• The Zenfone line has been called an unremarkable big-screen smartphone that does nothing wrong but is eclipsed by stronger competition.

Google Pixel 10a

Holding the price at $499 in a year of RAM shortages and broad consumer-electronics inflation is itself a small win — Samsung's Galaxy S26 line all saw price increases this cycle. But the elephant in every review is the Pixel 9a still on Google's store at the same price, and on retailer sale for ~$100 less. The iPhone 17e's MagSafe + A19 upgrade, plus the Nothing Phone 4a Pro's telephoto + 50W charging at the same $499, give the 10a real same-price competition for the first time. Reviewers split: about half explicitly recommend the cheaper 9a; the other half argue the flush camera, Gorilla Glass 7i and Satellite SOS justify the new model for first-time A-series buyers.

• It's probably still the best $500 you can spend on an Android phone — but if you can pick up a Pixel 9a for even a few bucks cheaper, you should do that instead.
• The Nothing Phone 4a Pro at the same $499 poses tough competition with a bigger and brighter screen, a Qualcomm processor, a dedicated telephoto lens, and 50W charging — making the Pixel 10a a tougher sell.
• The Pixel 10a is still $500, the same price as the Pixel 7a from three years ago — against the backdrop of RAM-shortage inflation, flat pricing is more remarkable than it sounds.
• Apple's iPhone 17e is the same price as the iPhone 16e but adds MagSafe and a class-leading A19 chip while doubling base storage — making Google look lazy by comparison.
