How long will it last?
Our estimateSupported until July 2028 · Buy-by July 2026
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 1.9 years of safe use, and Apple's written legal minimum is 5 years (verified July 2026).

TrueCost
Street price ÷ months of safe use remaining — the number that makes cheap short-lived phones expensive, and well-supported ones cheap.
23% cheaper than the under-$300 median ($6.38/mo, dying phones excluded)
Is the Spark 40 worth buying in 2026?
With caution — only 23 months of updates are left ($4.93/month of safe use). Fine as a short-term or budget pick, risky as a long-term keeper.
Our verdict
The entry rung of the Spark 40 family pairs 45W charging with a 120Hz LCD for around $115, but the 12nm Helio G81 and single expected OS upgrade cap how long it stays current.
Pros
- 45W charging is genuinely rare at this price and refills in under an hour
- IP64 plus a claimed 1.5m drop rating for a plastic budget phone
- 120Hz panel keeps scrolling smooth despite the modest chip
- microSD slot and up to 256GB built in
Cons
- HD+ LCD looks soft next to the AMOLED Pro models
- Helio G81 is a 12nm part already several generations old
- Likely one HiOS upgrade only, with patches ending around mid-2028

Frequently asked questions
Is the Spark 40 still supported?
Yes. It launched in July 2025 running Android 15 with HiOS 15 and still receives Tecno's periodic patches. Based on Tecno's Spark track record, security coverage should run to about July 2028.
How long will the Spark 40 get updates?
Expect roughly one major HiOS upgrade, taking it to Android 16, plus about three years of security patches. That places the practical end of support near July 2028.
Is the Spark 40 worth buying in 2026?
At around $115 with two more covered years, it is cheap insurance for a first or backup phone. If you want a display worth watching video on, the Spark 40 Pro's AMOLED is the better $60 upgrade.
What is the difference between the Spark 40 and the Spark 40 5G?
They are different phones. The 5G model uses a Dimensity 6400 with a 6000mAh battery but only 18W charging, while this 4G version keeps 45W charging and the Helio G81.
