Tecno Spark 40
By Muhammad Tahir · Updated July 2026 · how we review
The cheapest Spark 40 gets 45W charging and a 120Hz refresh rate for about $115, which is genuinely generous — but a 12nm Helio G81, a 720p panel and one expected OS upgrade make it a phone for right now, not for keeping.
Is the Spark 40 still supported?
Our estimateSupported until July 2028 · Buy-by July 2026
✓ Yes — the Spark 40 is expected to be supported until July 2028, roughly 1.8 more years.
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the Spark 40 should be supported until around July 2028. Buying it today still gets you about 1.8 years of safe use, and Apple's written legal minimum is 5 years (verified July 2026).

Should you buy the Spark 40 in 2026?
Pros
- 45W wired charging at $115 is exceptional; a full charge takes about 55 minutes
- 120Hz refresh rate keeps the interface smooth despite the basic panel
- 5,200mAh battery with a low-resolution screen delivers long life
- microSDXC expansion and an FM radio, both increasingly rare
Cons
- Helio G81 is a 12nm chip — old silicon that limits both speed and efficiency
- 4G only, with no 5G option at all
- HD+ 720 x 1600 resolution looks soft on a 6.67-inch screen
- One expected OS upgrade means it will be on outdated Android quickly

Frequently asked questions
What is the Tecno Spark 40 update policy?
There is no published policy. Tecno does not commit to update windows for the Spark family in writing, so our figures are estimates from observed behaviour: about one Android version upgrade and roughly three years of security patches from the July 2025 launch, putting the end of support near July 2028. At this price point patches are usually the first thing to quietly stop, so we would treat that as the optimistic case.
How many Android updates will the Tecno Spark 40 get?
We expect one. It shipped on Android 15 with HiOS 15, so realistically it reaches Android 16 and stops. Entry-level phones carry the thinnest update commitments across the whole industry, and Tecno's cheapest tier is no exception — if running current Android matters to you, this is not the phone for it.
Is the Tecno Spark 40 fast enough?
For messaging, calls, social media and video, yes. The Helio G81 is a 12nm chip that first appeared years ago, and it shows under any real load — demanding games, heavy multitasking and large app installs are all slow. The 120Hz screen papers over some of this in everyday scrolling, but the underlying silicon is entry-level and feels it.
