We’ve been putting the Tecno Camon 40 Premier 5G through its paces, focusing on one area that matters most to users — battery life. While the hardware upgrades from its predecessor, the Camon 30 Premier, are clear on paper, how do they translate to real-world endurance? Let’s break it down.
Battery Capacity
The Tecno Camon 40 Premier 5G comes with a 5,100mAh battery. That’s just a 100mAh increase over the Camon 30 Premier’s 5,000mAh unit. Tecno made the shift to Si/C (Silicon Carbon) battery tech this year, which allows for a more compact cell with slightly better energy density. However, the jump in raw capacity is minimal, and not something you’ll feel day to day.
So why does this matter? It doesn’t — until you factor in the rest of the hardware improvements.
Chipset Upgrade
This is where things get more interesting. The new Camon 40 Premier is powered by the MediaTek Dimensity 8350, a chip built on TSMC’s newer N4P fabrication node. This is an upgrade from the Dimensity 8200 Ultimate on the Camon 30 Premier, which was fabbed on the older N4 process.
Not only is the node more efficient, but the CPU cores are newer too — Cortex-A715 and A510, replacing the previous generation’s A78 and A55. These cores offer better performance per watt, meaning more efficient use of power even during demanding tasks.
In real-world use, this leads to less drain during background processing, better idle power management, and smoother multitasking without ramping up battery consumption.
Display Efficiency
The display on the Camon 40 Premier has also seen a subtle shift. It’s now a 6.67-inch AMOLED panel, slightly smaller than the 6.77-inch unit on the Camon 30 Premier. Pixel density remains about the same, since the resolution is quite close. While the difference might seem minor, a smaller display can contribute to better battery performance — especially when paired with better display drivers and tuning.
Real-World Battery Usage
In our testing so far, the Camon 40 Premier 5G consistently lasts longer than its predecessor under similar usage patterns. With light to moderate use — including social media, YouTube streaming, and occasional gaming — the phone can easily stretch over a day and a half. More intensive usage brings it closer to a full-day device, but it still holds up well.
This improved efficiency is mostly down to the updated chipset and display tweaks. Even though the battery capacity bump is small, the internal upgrades help the phone do more with less.
Here’s a quick comparison of key battery-related upgrades:
| Feature | Camon 30 Premier | Camon 40 Premier |
|---|---|---|
| Battery Capacity | 5,000mAh | 5,100mAh |
| Battery Tech | Standard Li-Po | Si/C (Silicon Carbon) |
| Chipset | Dimensity 8200 Ultimate | Dimensity 8350 |
| Chip Node | TSMC N4 | TSMC N4P |
| CPU Cores | A78 / A55 | A715 / A510 |
| Display Size | 6.77-inch | 6.67-inch |
| Endurance (Usage-Based) | ~1 Day | ~1.5 Days |
The Tecno Camon 40 Premier 5G doesn’t wow with a huge battery capacity increase, but it quietly improves where it counts — efficiency. Thanks to a smarter chipset and a more refined display setup, it delivers longer battery life without needing a much bigger cell. If you’re looking for a device that balances power and longevity, this phone is off to a promising start in our tests.
