We have been testing the Tecno Camon 40 Pro (the 5G variant) and wanted to share our battery life findings. The phone is equipped with a 5,200mAh battery (with 45W wired charging) and features a curved 6.78” OLED display running at up to 144Hz. It’s powered by a Dimensity 7300, a 4nm chip from the TSMC fabs.
Battery life test
The Camon 30 Pro from last year has a slightly smaller 5,000mAh battery but a higher-end Dimensity 8200 Ultimate (which is fabbed on the same 4nm node as the 7300). The extra performance helped in the gaming test where the old model lasted an hour longer. It also had the upper hand in the call test, while the web and video tests are quite close – this gave the 2024 Pro an extra 40 minutes of Active use score.
The recent Motorola Edge 60 Fusion makes for an interesting point of comparison – the global model (which is the one we tested) uses the same Dimensity 7300 chip and the battery has the same 5,200mAh capacity. The screen is a bit smaller, but it has a higher resolution – 6.67” 1220p+ for the Motorola compared to 6.78” 1080p+ for the Tecno. It has an advantage of over 2 hours in the video playback test, which was enough to outscore the Tecno by a small margin.
Tecno Camon 40 Pro
The Infinix Note 50 Pro+ also makes for an interesting comparison – it has a 6.78” 144Hz display, just like the Tecno (it’s flat but that doesn’t affect power usage) and the same 5,200mAh battery. However, it uses a Dimensity 8350, which is built on a more advanced N4P node. Unlike with the Camon 30 Pro, the 8000-series chip fell hard in the gaming test. The web and video tests are noticeably lower than the Camon 40 Pro too. This puts the Infinix two hours lower than the Tecno.
The Poco X7 runs on the Dimensity 7300 Ultra (a minor variation of the 7300) and 5,110mAh batteries (just 90mAh less than the Tecno). It has a smaller, sharper 6.67” 1220p+ display that has a 120Hz refresh rate. While the hardware appears close, the X7 is down 2 and a half hours in the Active use score with worse results across the board.
Charging speed test
The Tecno Camon 40 Pro supports 45W chargers – it even ships with one in the box. That’s a lower rating than the previous model, the Camon 30 Pro, which supports (and ships with) a 70W charger.
The Camon 40 Pro is off to a slow start – it doesn’t help that most of its rivals support higher charge rates. Sure, some of them have smaller batteries, but the 90mAh difference with the Poco X7 (the only other phone with 45W charging in the list) isn’t enough to account for the 8 percentage point difference at the 15 minute mark.
X7’s lead extends at the 30 minute mark. Meanwhile, the Infinix Note 50 Pro+ has essentially crossed the finish line at this point. The Motorola Edge 60 Fusion (which has the same 5,200mAh battery) shows the advantage of its higher 68W rating. Interestingly, the Tecno Camon 40 Pro beat the Poco X7 to 100% – just by a minute, but it’s still unexpected, given that it was behind at 15 and 30 minutes. The Motorola got to 100% 20 minutes faster than the Tecno. The Camon was also beaten by its predecessor by 15 minutes.
Verdict
The Tecno Camon 40 Pro has very good battery life compared to its peers and charge speed is okay if you charge to 100%. Quick top-ups are not so quick however. It’s hard not to notice the downgrade compared to the Camon 30 Pro – the 2024 model lasted longer (with a smaller battery no less) and charged faster. Those are not the only downgrades either, in the review we will go over performance and cameras too (the 30 Pro had a 50MP ultra-wide, the 40 Pro has an 8MP module).
