TECNO has another Slim phone in the oven, and this time it is wearing Camon colours.
A new device labelled the TECNO Camon Slim has shown up on multiple certification databases over the past week, including the FCC, TΓV, and TECNO’s own Carlcare after-sales portal. The listings, first spotted by Gizmochina, give us the first real look at what TECNO is cooking up for the next chapter of its Camon line.
The phone carries the model number CN6c. It comes with 8GB of RAM and ships in either 128GB or 256GB storage configurations. Those are sensible numbers for a mid-range device.
But the headline is the battery.
According to the FCC filing, the Camon Slim uses a battery pack identified as BL-68DX, with a typical capacity of 7000mAh and a rated capacity of 6840mAh. The same documents confirm support for 60W wired charging through TECNO’s U600TSA power adapter.
If that pairing sounds odd, that is because it is. A 7000mAh cell is the kind of battery you normally see in a gaming phone or a chunky budget device, not in something a manufacturer is calling “Slim.”
Why this is interesting, and a little confusing
TECNO has been on a Slim crusade for about a year now. We already covered how the original Spark Slim launched in Kenya at KES 27,999 with a 5.95mm chassis and a 5160mAh battery. Earlier in 2026, TECNO took it further at MWC with the Spark Slim 2, a 5.49mm concept that managed to pack 6150mAh inside a ceramic body.
So a Camon Slim is the next logical step. TECNO is moving the Slim sub-branding out of the Spark family and into the Camon family, which has historically been about cameras rather than form factor.
The confusing part is the timing. TECNO only just launched the standard Camon 50 series at MWC 2026, and the Camon 50 Pro already carries a 7000mAh battery alongside 80W charging. So if the Camon Slim also has a 7000mAh cell, but with slower 60W charging and a slimmer body, where exactly does it sit in the lineup?
The likely answer is that this is not really a fourth Camon 50. It is a design-led variant. Same battery capacity, slightly slower charging, much thinner profile. Buyers who want the long battery life but care more about how the phone feels in the pocket than how fast it tops up.
How do you even put 7000mAh in a slim phone?
This is where the bigger industry story lives, and it is worth understanding.
For most of the last decade, smartphone batteries have used graphite anodes inside their lithium-ion cells. Graphite is cheap, stable, and well understood. But it has hit a ceiling on energy density. Once you want more capacity, you need a physically bigger battery, which means a thicker phone.
The workaround that has taken over flagship Android in 2026 is silicon-carbon battery technology. By replacing or supplementing graphite with silicon, manufacturers can store significantly more energy in the same physical volume. According to Tom’s Guide reporting on the shift, brands like Honor, OnePlus, and Oppo are using silicon-carbon cells to fit 7000mAh-plus batteries into phones under 8mm thick. Oppo’s Find X9, for instance, packs over 7000mAh into a 7.99mm body using its third-generation Si-C cells with 15% silicon content.
TECNO has not explicitly confirmed silicon-carbon chemistry for the Camon Slim, but the math more or less requires it. A 7000mAh battery in a genuinely slim chassis is not really possible with traditional lithium-ion. Either TECNO is using Si-C cells, or the phone is not actually that slim, in which case the “Slim” branding is mostly marketing.
The 60W charging spec is also a tell. Silicon-carbon cells can handle higher charging speeds safely, and 60W is the level at which a 7000mAh battery can realistically top up in under an hour without cooking itself.
What this means for Kenya
No pricing, no launch date yet. The certifications suggest an announcement is not far off, probably within the next two to three months given how quickly TECNO usually moves from FCC filing to retail.
For Kenyan buyers, the Camon Slim should land somewhere in the KES 30,000 to KES 40,000 range, sitting between the existing Spark Slim and the Camon 50 Pro. If TECNO can genuinely deliver a slim Camon with two-day battery life at that price, it will compete more with itself than with anyone else in the local market. The closest external rivals are the Infinix Note series and the Redmi Note 15 family, neither of which has matched TECNO’s thinness push.
The thing to watch is the actual thickness number. TECNO has not disclosed it yet, and the gap between “marketed as slim” and “actually slim” can be wide. A 7000mAh phone under 8mm thick would be genuinely impressive. A 7000mAh phone at 9mm or 10mm is just a normal phone with a Slim sticker on the box.
