The Nokia N810

The devices, in order: the N810 appeared in 2006, the N810 WiMAX followed in 2007, the N800 came in 2007 as the slimmer successor, and the N900 in 2009 as the final, most complete form of the line. Each step reused and extended the Maemo codebase, and The Nokia N900 is the device most former N810 owners moved to next. The Nokia N9 is a later and different story: a 2011 MeeGo handset with an optical trackpad instead of a keyboard, and it belongs to the next chapter rather than this one. The full thread of Maemo and the Nokia Linux line is mapped on its own page, so here the focus stays on the N810 itself.

The Nokia N810: release

The release of the Nokia N810 set it apart from every tablet before it. Nokia announced it at the Mobile World Congress in February 2006 and it reached European shelves in May 2006 at a street price around 600 euros. That put it below the US$1,000 line that laptops held, in a class of its own: the closest contemporary rivals were the 2005 Apple iPhone, which lacked both a physical keyboard and a real web browser, and Windows CE pocket PCs, which ran a different operating system family. The N810 was an open, Debian-based machine, and the developer community around maemo.org ported applications to it within months of the launch.

The Nokia N810: case

The case of the Nokia N810 is the part of the body an owner actually holds, and it is where the device ages most visibly. The front is a single slab of matte plastic around the 4.2 inch screen, and the back is a removable door held by a small screw at the bottom, which is the only fastener a battery swap ever needs. The sides carry the volume rocker, the power and lock switch, the headset jack, the USB port, and the slot for the microSD card, and none of them wear in any way that a 20 year old unit cannot still tolerate. What does wear is the case itself: the plastic yellowes where the light hits it, the screen bezel cracks along the corners of units that lived in a pocket, and the latch that seats the back door grows loose after years of opening and closing. The magnetic contacts under the keyboard are part of the case, and a case that no longer seats the keyboard flush is a case whose magnet or its steel plate has shifted, a repair that takes a small screwdriver and a steady hand. A replacement case for the N810 circulates on the used market as a single piece, and a fresh one resets the look of the machine more than any other swap does, because the case is what the eyes meet before the software loads. The 180 g of the body without the keyboard is the weight of that plastic, and it is light enough that a 2006 case still feels like a toy rather than a tool in the hand.

The Nokia N810: specifications

The specifications of the Nokia N810, in the figures that still matter to an owner today, read like this:

The 412 MHz PXA270 and 128 MB of RAM are modest by 2026 standards, but they carried a full GNOME-derived desktop, the Epiphany web browser, and a terminal emulator, which no phone of the year offered. The keyboard is the part people remember: 45 keys in a QWERTY layout, magnetic, detachable, and the typing surface that defined the device more than any spec. Two hardware generations shipped from the same mould: the standard N810 carried a 2 megabit GSM modem with GPRS, while the N810 WiMAX edition swapped that modem for a 1.25 GHz WiMAX radio, at a price of no phone calls at all. The WiMAX version appeared in 2007 for markets where WiMAX networks were live, and it remains the rarer of the two to find.

The Nokia N810: battery

The battery in the Nokia N810 is a single 1,500 mAh lithium-ion cell, and it is the first thing owners of a used unit should inspect. Nokia rated the stock pack at 8 to 10 hours of typical mixed use, with roughly 11 hours of continuous video playback, and that rating held on a fresh cell in 2006. Twenty years on, the honest figure is different: most surviving cells have lost the bulk of their capacity, and an N810 that dies mid-evening has a tired battery, not a tired motherboard. The battery seats in a door at the bottom of the case and holds a single small screw; it comes out by sliding it free, and it goes back by sliding it in until the latch clicks. When a used N810 arrives, the test is simple: fully charge it, note how long it actually lasts, and if it falls far short of the 8 hour floor, budget for a new cell before anything else.

The Nokia N810: kali

The Nokia N810 with kali on it is not a phone story and not a mainstream story. Kali is a penetration-testing distribution of Debian, and the N810 ran it in the way it ran anything else: as Debian packages on the same Maemo kernel, through the same package manager, on the same 412 MHz PXA270 and 128 MB of RAM. The community thread that carries the title is what an owner searching for it actually wants, and the honest summary of that thread is short. The device is a Debian box with a small screen and a great keyboard, so it runs the usual audit tools fine for lab and class work, and it is no faster at them than any 2006 hardware is. It will not be a daily field rig: 128 MB of RAM caps what the analysis tooling can hold open, the 2 GB of storage fills fast, and the Wi-Fi is 802.11b/g at best. As a teaching machine and a curiosity, though, an N810 that boots kali is a piece of the same open line as everything else this page describes, and it costs nothing to try on a spare unit with a charged battery.

The Nokia N810: battery life

The battery life of the Nokia N810, measured the way owners measure it, breaks into four modes. On video playback a fresh stock cell ran about 11 hours, which is where the marketing number came from. On web browsing with Wi-Fi the real-world figure was closer to 4 hours, because the 412 MHz PXA270 and the Epiphany browser burn power on every rendered page. In standby the device idles for days on a charge, since the GSM modem on the standard model sleeps cleanly and the Wi-Fi can be switched off entirely. And under the WiMAX radio of the 2007 edition the life dropped below the standard model, because a 1.25 GHz radio transmits harder than a 2 megabit GPRS link. The pattern matters more than any single number: an N810 that once held a full working day and now holds an afternoon is following the expected 20 year fade of a lithium-ion cell, and the remedy is in the next section, not in the settings.

The Nokia N810: battery extended

The battery life of the Nokia N810 extends in three ways, in order of effect. First, the settings that the community manual lists: drop the brightness, switch the Wi-Fi radio off when idle, and let the screen time out in 1 minute, and a tired cell regains a meaningful share of its day. Second, the cell itself: a 1,500 mAh replacement from the used market, fitted with the single screw and the sliding door, is the only change that moves the number back toward the 8 to 10 hour rating, and a healthy cell in a 2006 body still outlasts any phone battery of the 2005 year it answered to. Third, the load: Epiphany with a light page set and a terminal on the side is what the 412 MHz PXA270 and 128 MB of RAM were actually built for, and a browser that renders modern heavy pages is what empties even a fresh cell. The extended-life setup is not exotic, and it is the setup that made the N810 a daily carry for its first owners, which is the whole reason the device is still on desks 20 years after 2006.

The Nokia N810: replacement

The replacement parts for the Nokia N810 are the reason the device is repairable at all. The battery, the back door, the case, and the keyboard are the items that wear, and each one circulates on the used market. A replacement battery is a 1,500 mAh cell with the same footprint and the same single screw, and the fit is identical to the stock part. A replacement keyboard is a 45 key board with the same magnetic contacts, and the community manual for the N810 walks through removing the failed unit and seating the new one. A replacement case is a piece of plastic with a matching back door and the same two-finger clip, and it takes the yellowed, cracked, or worn unit back to a clean surface without touching the internals. Beyond the parts, the software has its own replacement: the Maemo Leste project, which rebased the whole OS on a 2021 kernel and a modern toolchain, ships a working image for the N800 and N900, and an N810 running a Leste-based build is the closest thing to a restored stock experience that exists, flashed from the project's own page, following its manual, with a charged battery and 10 spare minutes. The point of all of it is that an N810 from 2006 is not a disposable gadget: it is a machine whose every failing part has a known replacement, and that is rarer than the device itself is.

The Nokia N810: n770

The Nokia N770 and the Nokia N810 are the two ends of the same line, and the difference between them is the keyboard. The N770 appeared in 2005 as the first commercial Maemo device: an 800 MHz PXA270 tablet with a 200 GB option through the microSD slot of its 2 GB built in storage, a 4.3 inch screen, and no keyboard at all. The N810 arrived in 2006 as its successor and moved the clock back to 412 MHz, which reads as a downgrade until you understand the reason: the keyboard and the slimmer case needed a cooler, slower core, and the 412 MHz PXA270 drew less and ran the same Maemo OS 2006 kernel that the N770 carried as its OS 7.20 firmware. Owners who still hold N770 units treat them as the collectors' edition of the line: fewer were sold, the form is a pure slate, and the software ceiling is the same, since the N770 also stops at the 2006 branch. If a used N770 appears at a fair price, it is a fine second slate on the same open platform; if the goal is a daily machine, the N810 with its 45 key keyboard is the better of the two, for the same reason it won the argument against the N900 in the section below.

The keyboard: detachable, wireless, and the point of the device

The keyboard is why the N810 exists at all. It slid off its magnetic contacts, sat flat as a stand, and let the tablet work in two modes: a touch-only slate, or a two-handed typing machine. The keyboard was an external device in every sense: no cables, no ports to wear out, and a connection that survived a dropped half. Users who kept the device for a decade mostly kept it for this part, and replacement keys and shells surfaced on the used market long after Nokia stopped making them. When a keyboard stops registering, the usual culprits are the magnetic contacts, a bent key, or a cracked board, and the community manual for the N810 walks through each. The form was not without friction. The keys were small for large fingers, and the hinge wear on 2006 units makes some keyboards sit slightly loose today. Even so, the detachable external keyboard was years ahead of what the mainstream market would ship, and it shaped the follow-up design: the N900 kept the slide-out idea and built the keys into the body instead.

Nokia N810 vs Nokia N900

Choosing between an N810 and an N900 comes down to 3 hardware gaps and one software gap. The N900 is the more capable machine on every axis that a modern owner tests:

• Processor and memory: 412 MHz PXA270 with 128 MB of RAM on the N810, against 600 MHz ARM11 with 256 MB of RAM on the N900
• Screen: 4.2 inch at 240 by 320 pixels on the N810, against 3.5 inch at 480 by 800 pixels on the N900, double the resolution in a smaller body
• Radio: 802.11b/g Wi-Fi on the N810, against 802.11n on the N900, with 20 percent faster links on the same access point
• Keyboard: the N810's keyboard detaches and goes wireless; the N900's 39 key slide-out is fixed but better laid out and more durable
• Software: the N810 stops at OS 2007, while the N900 runs Maemo 5, the final official release of the platform

The N810 holds 2 advantages: its detachable keyboard, and a longer, more forgiving battery life at idle, which helps a device 20 years old. If you want the better machine, the N900 wins on 4 of 5 points. If you want the slimmest possible slate with a keyboard in your pocket, or you are hunting the rarer WiMAX radio, the N810 keeps its place. Neither device runs android, and no credible android port for either one has ever shipped; both speak Linux, and both still boot, still connect to Wi-Fi, and still render the open web with Epiphany, if slowly.

What it ran, and what still runs on it

The N810 ran OS 2006 at launch, received the OS 2007 firmware in 2007, and then stopped, because Nokia moved its Linux effort to the N800 and the N900 and closed the N810 branch. Everything on the stock firmware is open: the kernel, the X11 desktop, the Epiphany browser, and the package manager, which pulls Debian-derived packages from the community repositories. The community kept the platform alive with a few long-tail additions, such as a newer kernel, an updated web engine for pages the 2007 browser no longer renders, and the Maemo Leste project, which rebased the whole OS on a 2021 kernel and a modern toolchain and ships a working image for the N800 and N900. The firmware on the device is a snapshot of 2006 Linux, and that is part of what an owner is actually buying: not a phone, not an android relic, but a small, self-contained, 20 year old computer that still answers to its keyboard.
