Six weeks of battery testing, NPU audits, resale tracking, and a $233 upgrade experiment to answer one question: is a Copilot+ PC worth it in 2026?
Your three-year-old laptop is not obsolete — the AI laptop marketing machine just needs you to believe it is. I spent six weeks running a 2026 Copilot+ PC and a 2023 ThinkPad through identical workdays, and the NPU changed almost nothing about how I worked. A $233 RAM-and-SSD upgrade changed everything. Here's the head-to-head, including the battery drain, resale, and upgrade math the benchmark charts conveniently leave out.
The Contenders
Two machines, one desk, six weeks.
The AI laptop: Dell XPS 13 (2026). Snapdragon X Elite X1E-80-100 with a 45 TOPS Hexagon NPU, 16GB LPDDR5x (soldered — zero upgrade path), 512GB PCIe 4.0 SSD, 13.4-inch 3K OLED, 55Wh battery. $1,349.
The last-gen keeper: Lenovo ThinkPad T14 Gen 4. Core i7-1355U with an NPU under 10 TOPS, which means it is not Copilot+ eligible at all. 16GB DDR5 across two SODIMM slots with one free, 512GB NVMe, 14-inch 1920×1200 IPS, 52.5Wh battery. Bought new for $1,180 in 2023; sold listings in early 2026 run $480–$560.
I also cross-checked three reference points: the Samsung Galaxy Book5 Pro (Intel Lunar Lake, 47 TOPS), the MacBook Air M4 (not Copilot+ at all, but the comparison everyone asks about), and the Framework Laptop 13, the only mainstream machine where the upgrade question has a clean, honest answer.
What We Tested
Six weeks of daily dual-machine use, roughly 60 hours per machine of Word, Slack, 30-tab Chrome, Spotify, and Zoom. Battery was measured two ways: a scripted loop (ten tabs, 200 nits, Wi-Fi on, a 20-minute video call every hour) and a real-day log I kept in a spreadsheet like a nerd.
NPU features tested: Windows Studio Effects, Live Captions with live translation, Cocreator in Paint, Recall, and Auto Super Resolution across three games. Upgrades tested: a 32GB DDR5-5600 SODIMM kit and a 2TB Gen 4 NVMe drive. Resale values were pulled from 30 days of sold listings — actual sales, not asking prices, which is where most resale advice quietly falls apart.
Design & Build
The XPS 13 is the better object. It's thinner, the OLED panel is genuinely lovely, and the CNC aluminium chassis has zero flex. But "better object" and "better purchase" are different questions, and build quality is exactly where the ThinkPad claws back ground.
Two things matter here. First, ports: the XPS 13 gives you two Thunderbolt 4 ports and nothing else, so a dock is mandatory. The ThinkPad T14 has two USB-A, two USB-C, HDMI, and Ethernet — no dongle tax. Second, and far more important: the XPS 13's memory is soldered to the board. That $1,349 laptop has a fixed ceiling, and in 2029 it will still have 16GB of RAM and no path upward. The ThinkPad has an empty SODIMM slot and a standard M.2 2280 bay.
That single design decision is the whole article in miniature. One machine is a sealed object with a countdown timer. The other is a set of parts you can extend.
The Framework Laptop 13 goes further still — mainboard swaps let you upgrade the entire compute module while keeping the chassis, screen, and keyboard. It's a niche purchase with niche pricing, but it's the only laptop I've tested where "upgrade" doesn't mean "replace."
Performance
For everyday work — documents, browsers, spreadsheets, video calls — the two machines feel identical. I genuinely could not tell you which one I was typing on without looking. The XPS 13 wins on single-core and on anything GPU-adjacent; the ThinkPad wins nothing on raw speed. But nothing in my actual job required more than either offered.
The NPU: What You'll Actually Use
The Copilot+ PC runs a 45 TOPS NPU. The requirement to be called a Copilot+ PC in 2026 is 40 TOPS. Here's what that hardware unlocked in six weeks of honest testing:
- Windows Studio Effects (background blur, eye contact, auto framing) — works, looks good, and is genuinely useful on calls. It also runs fine on the older ThinkPad via CPU, it just costs more battery.
- Live Captions with live translation — the one feature I'd miss. It translated a Spanish-language video call in near-real-time with only occasional slips. This does require the NPU.
- Cocreator in Paint — I used it once, for this article's header image, and it took 40 seconds to produce something mediocre.
- Recall — I enabled it for a week, found it mildly useful twice, and turned it off because I didn't love the idea of a searchable screenshot log of my entire life.
- Auto Super Resolution — genuinely clever in supported games, irrelevant if you don't game on a 13-inch ultraportable.
That's the honest ledger: one feature I'd actually miss, one I use weekly on calls, and three I could delete tomorrow. If you're buying an AI laptop in 2026 for the AI features specifically, you're paying a lot for a translation tool and background blur.
Battery Drain, Measured
This is where the new machine earns its keep. On the scripted loop at 200 nits:
- Dell XPS 13 (Snapdragon X Elite, OLED): 11 hours 5 minutes
- Samsung Galaxy Book5 Pro (Lunar Lake): 10 hours 20 minutes
- ThinkPad T14 Gen 4, brand new (2023 measurement): 7 hours 20 minutes
- ThinkPad T14 Gen 4, today at 81% battery health: 5 hours 50 minutes
That last number is the one nobody puts in a review. Lithium batteries lose capacity, and a three-year-old laptop at 81% health isn't a fair fight against a fresh one. A replacement battery for the T14 runs $70–$90 and restored our test unit to roughly 6 hours 50 minutes — not new-laptop numbers, but comfortably a full workday with a coffee break.
The gap is real: about 4–5 hours of extra runtime in the AI laptop's favour. If you work unplugged all day, that's not a marketing claim, it's your afternoon.
Why the Old Laptop Felt Slower (and the $233 Fix)
Here's the part that surprised me. The ThinkPad felt sluggish in weeks one and two — not because of the CPU, but because 512GB was 91% full and Windows was swapping to disk constantly. I installed a Crucial 32GB DDR5-5600 SODIMM kit ($84) and a Samsung 990 Pro 2TB NVMe SSD ($149). Total: $233 and 25 minutes with a screwdriver.
The result was a laptop that felt new. Cold boot dropped from 34 seconds to 11. Sixty-tab Chrome sessions stopped stuttering. File searches went instant. It still won't do Live Captions translation, and it still gets six-ish hours of battery — but for the work I actually do, the $233 ThinkPad is not meaningfully behind a $1,349 Copilot+ PC.
Price & Value
Let's do the math everyone skips.
| Copilot+ PC (XPS 13) | 2023 ThinkPad + upgrades | |
|---|---|---|
| Purchase price | $1,349 | $0 (already owned) |
| Upgrade cost | $0 (nothing upgradable) | $233 |
| Battery replacement | n/a | $80 |
| 3-year resale estimate | ~$600–$700 | ~$400 |
| Net cost over 3 years | ~$700 | ~$313 |
Resale Value
AI laptops depreciate faster than the machines they replace, and the reason is structural: the NPU generation number is now a spec people shop by, so a 45 TOPS machine looks dated the moment 80 TOPS ships. Tracking sold listings, current Copilot+ ultraportables are holding roughly 55–60% of purchase price at the 12-month mark. The ThinkPad T14 Gen 4, three years old, is holding about 43% of its original price — worse in percentage terms, but it started lower and the absolute dollars lost per year are far smaller.
Buy the AI laptop and you're accepting a steeper annual depreciation curve in exchange for battery life and a handful of NPU features. That's a legitimate trade. It is not, however, the trade the marketing implies.
The Upgrade Math
A RAM-and-storage refresh on a serviceable laptop costs $200–$280 in 2026 and buys you roughly two more comfortable years. A new Copilot+ PC costs $1,100–$1,400. The break-even point only comes if you'd otherwise be replacing the machine anyway.
One caveat, and it's a big one: this only works on laptops with SODIMM slots and standard M.2 bays. Most thin-and-lights sold since 2023 — including the XPS 13 — have soldered memory. Check your specific model's service manual before you buy a single stick of RAM.
Who Should Buy Which
Buy a Copilot+ PC if: you're unplugged 6+ hours a day, you need live translation, you're on video calls constantly, or you're replacing a laptop that's already failing. The battery life alone justifies the price for frequent travellers.
Keep and upgrade your 2023–2024 laptop if: it has SODIMM slots, it's under 85% battery health only because of age, and your work is browser-and-Office shaped. Spend the $233, replace the battery, and revisit in 2028.
Buy the Framework Laptop 13 if: you want Copilot+ performance now and a genuine upgrade path later. You'll pay a premium and give up some polish.
Buy the MacBook Air M4 if: you don't need Copilot+ features specifically. It's not a Copilot+ PC, but it's the best battery-per-dollar laptop I've tested this year.
Don't buy any of them if: your current machine has 16GB of RAM, an SSD under 70% full, and healthy battery. You have no problem to solve.
Bottom Line
The AI laptop is a better laptop. It is not a necessary one. If you're buying new in 2026, the Dell XPS 13 (2026) and Samsung Galaxy Book5 Pro are genuinely excellent machines, and the battery advantage is the real reason to buy — not the NPU badge.
But if you already own a 2023 or 2024 laptop with accessible internals, the smart money is a 32GB RAM kit, a 2TB SSD, and a fresh battery: about $313 total for two more good years. That's a laptop upgrade, and it costs 77% less than a new Copilot+ PC.
The controversial claim I opened with? Six weeks of testing didn't shake it. The honest answer to "is a Copilot+ PC worth it in 2026" is that it's worth it for the battery, not the AI.
Frequently Asked Questions
What is the difference between a Copilot+ PC and a regular laptop?
A Copilot+ PC is a Microsoft certification, not a new class of computer. It requires an NPU rated at 40 TOPS or more, plus 16GB RAM and 256GB storage, which unlocks on-device features like Recall, live caption translation and Cocreator. A regular laptop runs the same Windows, same apps and same Copilot chat — it just handles AI tasks on the CPU or in the cloud instead.
Can you upgrade the RAM in a Copilot+ PC?
Usually not. Most Copilot+ laptops use soldered LPDDR5x memory to hit the efficiency and thickness targets the certification encourages, so the RAM you buy is the RAM you keep for the machine's life. A few models, including Framework's, use socketed SODIMMs. Check the spec sheet for SODIMM slots before buying if you plan to keep the laptop past four years.
Do you need a Copilot+ PC to use AI features on Windows?
No. Most AI features work on older hardware — Windows Studio Effects runs on a regular CPU, and Copilot itself is largely cloud-based. The NPU-exclusive exceptions are limited: Live Captions with live translation, Recall and Cocreator in Paint. If those three don't matter to your workflow, a non-Copilot+ laptop delivers nearly the same day-to-day experience.
How long should a laptop last before you replace it?
Realistically five to seven years for general work, and a 2023 machine is nowhere near that line. The usual retirement triggers are a worn battery, insufficient RAM and a dropped Windows support window — not slow CPUs. If your laptop has socketed memory and a replaceable SSD, a modest upgrade can extend its useful life by several years.
