Five Phones, and What the Spec Table Hides

Four 2026 phones are compared here against one 2024 incumbent — the Nothing Phone (2a) — because a five-way spec table flatters every newer device equally. It shows what a phone has; it never shows what a phone removes. Read as deltas instead: all four candidates degrade or delete the baseline's 50 MP ultrawide; the largest single gain in the set is a 70% battery increase, not anything on the camera; and the only like-for-like price comparison available is a NT$2,000 step between two same-family siblings, not the headline gap between brands.

The Short Answer what actually separates them

As a spec table, all four 2026 candidates beat the baseline. As deltas, they separate into three answers. The two same-family siblings differ by exactly NT$2,000 at identical configuration: the cheaper one already carries IP68, the faster memory generation, 100 W charging and a 30.0% larger battery, and is the lightest and smallest 2026 device here; the dearer one adds a 3 nm chip tier, 30.8% more battery again, Wi-Fi 7 and eSIM — and buys zero extra software support, no camera improvement and no measurable brightness gain, at 16.53 g more. The premium candidate earns its 1.50× price on one capability nothing else offers — an optical telephoto — plus the only 144 Hz panel, aluminium unibody and 32 MP front camera here. The budget candidate is capable at NT$5,890 but is no successor: it removes the ultrawide entirely and loses stabilisation.

Bottom line

Every candidate here is a camera regression against the 2024 baseline on at least one axis, and three of the four regress on the same one. A spec table shows what a phone has; it never shows what it removes.

Reframe

With both siblings present the choice is no longer one question but three: whether the zoom justifies its premium, whether the larger sibling's headroom justifies NT$2,000, or whether the difference is better left unspent.

Taiwan pricing here rests on one first-party capture rather than a mix of channels. On the manufacturer's own Taiwan store, filtered to an identical 12 GB/512 GB configuration and read the same day, the two same-family siblings are NT$11,999 and NT$13,999 — a NT$2,000 step, or 16.67%. That is the only fully like-for-like price comparison in this document. Both carry a struck list price exactly NT$2,000 above the model's launch list — a uniform uplift that inflates the advertised saving on both without distorting the gap between them, so the real cuts are NT$1,000 and NT$2,000 rather than the advertised NT$3,000 and NT$4,000. Against the cheapest authorised dealer the store sits NT$309 over on the smaller sibling and NT$9 over on the larger. The budget model sells at NT$5,890 in a smaller 8 GB/256 GB configuration, quoted by 40 separate retailers. The premium candidate is the exception: no street price exists in any Taiwanese source reached — the largest local price-comparison platform shows 無報價, no quote — so only its NT$17,990 list price can be cited.

轉 — What Every Candidate Takes Away the part a spec table omits

Device	Advance	Regression
Nothing (4a) Pro	The set's only optical telephoto — 50 MP 3.5× periscope, stabilised. Also its only 144 Hz panel, only aluminium unibody, and the only 32 MP front camera among the 2026 candidates — 60.0% more selfie resolution. Security tail 4 → 6 years.	Ultrawide falls to 8 MP and 47.6% of the baseline's sensor area. Memory stays LPDDR4X / UFS 3.1 while both cheaper rivals ship LPDDR5X / UFS 4.1. Its cell is 78.2% of the smaller sibling's and 59.8% of the larger's. +20 g. USB 2.0. Still three OS updates.
POCO X8 Pro	+30.0% battery and +122.2% charging at the lowest 2026 price here. Uncontested IP68. LPDDR5X / UFS 4.1, a 12-bit Dolby Vision panel and 3,840 Hz dimming. The lightest and smallest 2026 candidate at 201.47 g. Four OS and six security years — identical to its larger sibling.	Ultrawide −84%. Front camera −37.5%. Main sensor 64.0% of the baseline's area. The only candidate whose screen shrinks — 6.59″, up to −2.8%. No eSIM. An optical rather than ultrasonic reader, and that reading is itself disputed. Runs warm: one 3DMark run peaked at 43 °C and throttled twice.
POCO X8 Pro Max	The largest single gain in the set — +70.0% battery, +122.2% charging. A 3 nm chip a tier above its sibling, +35.1% on the one within-source benchmark. Most pixels (+35.7%). Wi-Fi 7, eSIM, an ultrasonic reader and an uncontested IP68.	Ultrawide −84%. Front camera −37.5%. 218 g — the heaviest here, +14.7%. For its NT$2,000 premium it buys zero extra software support, no camera change, and no measurable brightness gain: 634 against 633 nits. Sustained-load thermal behaviour is disputed between reviewers.
POCO M8 5G	+10.4% battery while 6.3% lighter and 14.0% thinner. IP66. 256 GB base plus microSD to 1 TB — the only expandable device here. Four OS and six security years.	No ultrawide at all. Optical stabilisation lost. Main sensor 29.3% of the baseline's area. Front camera −37.5%. UFS 2.2. Bluetooth 5.1. Charging unchanged at 45 W.
Shared by all four	Every candidate extends the security tail from four years to six — 50.0% longer than the baseline — and three of the four add a fourth OS update.	All four degrade or delete the ultrawide. Within this set the baseline's 50 MP wide-angle cannot be carried forward at any price. All three POCO models also ship manufacturer software carrying ad-serving components and 35–50 preinstalled apps.

The Arithmetic Behind It sensor area scales as (1/x)², not as megapixels

2.10×baseline ultrawide area vs the (4a) Pro's — (4.0 ÷ 2.76)² = 1.4493²
1.56×baseline main sensor vs either X8 sibling's — (1.95 ÷ 1.56)² = 1.25²; partly offset by an f/1.5 lens
3.41×baseline main sensor vs the M8 5G's — (2.88 ÷ 1.56)² = 1.8462²; no stabilisation to compensate
Nonedefensible benchmark figure spanning the whole set: scores come from three sources and versions and cannot be combined. Only within-source steps are quoted.

合 — Which Device Answers Which Question conditions attached

The zoom question comes first. Only the (4a) Pro has an optical telephoto — at 1.50× the cheaper sibling's price and 1.29× the larger one's, and at the cost of a chip tier, a memory generation and an OS update.
The NT$2,000 sibling step is the clearest trade here. It buys 30.8% more battery, a 3 nm chip tier, Wi-Fi 7 and eSIM; it buys no extra software support, no camera change and 16.53 g.
Match the configuration before comparing prices. The smaller sibling's widely quoted NT$9,790 is an 8 GB/256 GB unit; set against a 12 GB/512 GB rival it overstates the gap by NT$2,209.
Read struck-through prices against launch list, and treat deep marketplace discounts with care. Both siblings' struck prices sit exactly NT$2,000 above their launch lists; and listings well below the authorised-dealer floor are likely parallel imports without local warranty.
Verify the ingress rating before relying on it. The (4a) Pro's is disputed between IP65 and IP68 and the maker publishes no figure; both X8 models' IP68 is consistent across sources.
Weigh the support clock and the date on every price. The baseline's security updates end around March 2028 and its OS updates stop at Android 17; every candidate extends that to roughly 2032. All figures read 1–2 Aug 2026; no promotion carried a published end date.

Where it lands

Three questions, not one. The premium candidate answers only the zoom question, at 1.50× the cheapest 2026 candidate. The larger sibling answers the headroom question for NT$2,000 — and nothing at all on software life or camera. The smaller sibling answers neither and gives up least: IP68, LPDDR5X / UFS 4.1, 100 W and the same four-OS commitment, at 66.7% of the premium price. And whichever is chosen, the high-resolution ultrawide does not survive the move.

The unresolved items

Five points remain unsettled: the (4a) Pro's ingress rating (three sources IP65, one IP68, the maker publishes none); the smaller X8's fingerprint type; the larger X8's behaviour under sustained load; whether the larger X8's local retail box contains its charger; and whether the budget model ships Wi-Fi 5 or 6. All five are reported as conflicts, not as facts.
