Choose the Lenovo Tab One over the renewed Tab M9, unless metal matters more than support

The winner is newer, not faster enough to brag about

The Tab One uses a MediaTek Helio G85, while the M9 uses the closely related Helio G80. That gives the newer tablet a modest platform advantage, but not one that changes the class of work either device can handle. Reading apps, email, streaming, light browsing and casual games are reasonable; demanding 3D games, frequent split-screen work and constant app switching are not.

Storage is another near draw. Each listing provides 64 GB of eMMC storage and a microSD slot, so downloaded films, books, music and personal files can live on a card. Neither should be mistaken for a 64 GB device with 64 GB free, and Android may not allow every app to move to removable storage. Our guide to choosing tablet storage explains why a microSD card helps without fixing slow internal storage.

Two coarse screens, two different kinds of disappointment

The Tab One’s 8.7-inch panel and the M9’s 9-inch panel share the same 1340 × 800 resolution. The smaller Lenovo therefore has a slightly higher pixel density, but neither produces especially sharp small type. Novels with comfortable font sizes and video viewed at arm’s length are acceptable; technical PDFs, detailed comics and cramped websites reveal the shortage of pixels.

The M9’s Nook branding deserves particular skepticism. It is not an E Ink reader and does not become one when Reading Mode changes the color treatment. It remains a glossy, backlit LCD tablet that runs the Nook app. That versatility is useful for color books, recipes and video, but it cannot provide the paper-like surface, outdoor legibility or distraction resistance of a dedicated reader.

Laboratory work on the 4 GB and 64 GB Tab M9 found respectable brightness and contrast for its class, no detected pulse-width modulation and visibly soft detail at close range. Separate testing of the M9 also found reflections troublesome outdoors and pixel response slow. The screen is serviceable indoors, not a reason to buy the device for long reading sessions.

The M9 wins the materials contest and loses the ownership argument

Lenovo gave the M9 a metal rear panel, and that makes it feel more substantial than the Tab One’s plastic construction. Its 9-inch size also lands neatly between cramped 8-inch tablets and larger 10-inch models. If these were equally current new devices with equally clear warranties, the M9’s chassis would be a meaningful advantage.

They are not equally current devices. This M9 is renewed, and the listing does not establish who refurbished it, what cosmetic grade it must meet, how much battery capacity must remain or exactly which charging accessories arrive with it. New-unit battery tests cannot tell you how a particular renewed cell will behave. A return window helps only after the buyer spends time testing the uncertainty the seller should have resolved.

The Tab One’s plastic body is less luxurious but better suited to the reason for buying a small tablet. At 320 grams without the case and 4.91 inches wide, it is easier to carry and hold in one hand. The supplied folio protects the screen, provides a handhold and folds into a stand, although its shallow retaining groove can let the tablet slip when the display is tapped.

Battery claims favor both devices until renewal enters the room

Lenovo advertises up to 12.5 hours of YouTube streaming for the Tab One, and independent tests support a full day of restrained reading, browsing and video as a realistic expectation. Continuous maximum-brightness use shortens that result, while charging tops out at a modest 15 W.

The M9 was also capable of long video endurance when new, but this exact product is not new. Remaining battery capacity depends on its prior use and the refurbisher’s standard, neither of which is supplied. It also charges slowly at roughly 10 W, so a tired battery would be inconvenient in both directions.

Android support turns a close comparison into an easy one

The Tab One began with Android 14 and can update to Android 15, with a stated two-year security-patch commitment attached to the product. That is not a long support promise, and buyers should not assume Android 16 will arrive. It is still the more defensible starting point.

The M9 listing advertises Android 12 on a platform released in 2023. Some units received Android 13, but the available record does not justify expecting Android 14 or a durable future stream of security fixes. That makes it a poor choice for banking, sensitive work accounts or a family device expected to remain in daily service for years.

A narrow offline-media role lowers the practical stakes without repairing the support problem. Anyone seeking a device for school, personal communications or long ownership should consult the broader small-tablet recommendations rather than choosing between two compromised support policies.

Our ranked choices

The Lenovo Tab One is the compact tablet most buyers should choose.

Its newer software, lighter body, Google Play access and included folio create the more coherent package for travel, reading and streaming.

The low-resolution screen, slow eMMC storage and modest Helio G85 make sharp text and fluid multitasking unrealistic expectations.

The renewed Lenovo Tab M9 is only defensible as a limited secondary screen.

Its metal body, 4 GB of memory, 64 GB of expandable storage and ordinary Android app access suit indoor video and occasional color reading.

The aging software, coarse display and unstated refurbishment standards leave too much uncertainty for a reading-first or long-term purchase.

Choose by the job, not by the fraction of an inch

Specs & Screens treats the M9’s exact customer record as a warning rather than a calculated defect rate. Some owners describe smooth basic use, comfortable reading and enjoyable video, while another received a nonworking unit and a reading-first buyer reported troublesome page turns and movement-related glitches. The sample is too small to predict failure, but it is enough to make a clear return policy essential.

The final call

Buy the Lenovo Tab One if a genuinely small Android tablet will travel more often than a larger, better-equipped model. Its pauses and coarse text remain real, but the lightweight body, newer software position and included folio give those compromises a purpose.

Walk away from the renewed Tab M9 unless its metal build and secondary-screen role matter enough to justify checking the refurbisher, battery standard, warranty, accessories and return terms yourself. The Nook label is not a shortcut to a good e-reader, and an older renewed Android tablet is not the place to gamble on years of secure daily use.
