6 sourced reports, with what to check before you buy. Each one links to the page it was reported on.
An owner's own words describe the April 2026 update halving the 9a's usable day, matching Google's acknowledged bug. This is a real, current cost for a buyer.
What to check. Check the installed build before purchase; if it predates the September fix, the phone may not last a full day off a charge.

Google itself acknowledged a severe idle-drain bug affecting the Pixel 9a (fix only in the September update), so a buyer today can expect battery life cut roughly in half until that patch lands.
What to check. If you buy a Pixel 9a now, expect heavy idle battery drain until the September 2026 update; verify the update is installed before relying on all-day battery.
Reported on: 9to5google.com
Independent confirmation that the 9a's fix comes only in September, and that the bug caused heavy idle drain, high CPU use and warm phones even when idle. Users in the article dispute the fix is complete.
What to check. Corroborates the battery finding; budget for poor battery until the September update and verify it afterwards.

An owner-review aggregate (18 user opinions) reports the in-display fingerprint reader frequently fails to recognize the thumb and face unlock fails in low light. This is a day-to-day unlock annoyance, not a safety failure.
What to check. If reliable biometric unlock matters to you, test the fingerprint reader in store before buying; it is a known weak point.

The same owner-review aggregate reports the phone heats up noticeably during navigation and GPS signal is sometimes lost, alongside violently draining battery. Useful for buyers who use turn-by-turn navigation.
What to check. If you rely on GPS navigation for long drives, expect the 9a to run hot and occasionally drop the signal.

A Google support thread from an owner lists several simultaneous faults on one 9a (screen not waking, glitchy notification drawer, intermittent fingerprint, dim screen). Google's reply suggests a third-party app, so this may be software rather than hardware.
What to check. If you hit these symptoms, try Safe Mode to isolate a third-party app before assuming a hardware fault.

Kriko reads a listing and tells you which of these apply to that exact product. It runs on your computer, needs no account and is free.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
