It depends

Too close to call outright

Value Score: Galaxy S26 Ultra 76 · 17 72 methodology

Who should pick which

Beyond the scores — our take on each phone and the buyer it actually suits.

Samsung Galaxy S26 Ultra

Samsung's 2026 flagship pairs a built-in S Pen, a 200MP camera and faster 60W charging with the longest support runway you can buy — March 2033 — but the gains over the S25 Ultra are incremental.

Pick it if

  • Power users who want the S Pen
  • Long-term keepers wanting the maximum update runway
  • Zoom photographers who want dual telephoto reach

Skip it if

  • You own an S24 Ultra or S25 Ultra — the upgrade is thin
  • You want a compact, lighter phone or a lower price
Xiaomi 17

The Xiaomi 17 skips the unlucky '16' entirely, pairs the first Snapdragon 8 Elite Gen 5 with a 6-year security promise, so buying at mid-2026 still banks nearly six years of patches through February 2032.

Pick it if

  • Compact-flagship fans who don't want a phablet
  • Buyers who want maximum years of security patches from a 2026 purchase

Skip it if

  • You need a US carrier warranty and support
  • You want the bigger battery of the China-market variant

The lifespan decider

When specs are close, support length decides it — this is what each phone costs per month of safe use.

Frequently asked

How long will the Samsung Galaxy S26 Ultra get updates?

Until March 2033. Samsung promises seven generations of Android OS upgrades and seven years of security updates for the Galaxy S26 series, counted from its March 11, 2026 release. It launches on Android 16 and should reach Android 23.

Is the Galaxy S26 Ultra worth buying in 2026?

If you want the longest-lasting flagship and use the S Pen, yes — at the ~$1,099 street price you are paying roughly $13 per month across its 81 remaining months of support. If you already own an S24 or S25 Ultra, the year-over-year gains are too small to justify the cost.

How long will the Xiaomi 17 receive updates?

Xiaomi has committed to 4 major Android/HyperOS version upgrades and 6 years of security patches for the Xiaomi 17 series, putting end-of-support around February 2032 for the global model. Buying in mid-2026 still leaves roughly 5.5 years of safe ownership.

Why did Xiaomi skip the '16' name?

Xiaomi jumped straight from the 15 series to the 17 series to align its flagship numbering with Apple's iPhone naming cadence, a marketing move with no technical significance -- the 17 is a normal successor to the Xiaomi 15.
