2025 has been the first year in a long time that has brought important changes in the autonomy section, with some manufacturers incorporating silicon-carbon batteries that greatly increase the capacity without increasing the size of the battery or, by extension, that of the device. In this context, the study carried out by CNET is interesting, testing the endurance with a single charge of 35 mobile phones launched between 2024 and 2025.
The absolute winner has been iPhone 17 Pro Maxwhich is the most expensive model among those analyzed and the best in autonomy, despite having a relatively modest capacity of 5,088mAh. Call it efficiency, call it the biggest battery ever in an iPhone, but with the chip A19 Pro and iOS 26 has achieved the best result.
In the second position they tie the iPhone 17 and the OnePlus 15. The Chinese model has one of the largest batteries of those tested (7,300 mAh), while the iPhone 17 has the smallest (about 3,692 mAh) and still ranks among the best, which is a testament to the efficiency of the hardware and software of Apple.
OnePlus, on the other hand, remains with three positions in the top 5, all with silicon-carbon batterieswhile the rest use traditional lithium-ion ones.
Apple and OnePlus lead as brands with the best global autonomy. Motorola and Samsung They follow closely in third and fourth position, with very close results between the two. Google is fifth. It is striking that Google controls both the software and the design of the processor, just like Apple, and, Even so, their phones continue to lag behind in battery performance.
The top 5, due to ties, covers 9 models:
- 1st) iPhone 17 Pro Max.
- 2nd) iPhone 17 and OnePlus 15 (since there is a tie, CNET does not count a third position).
- 4th) iPhone 17 Pro.
- 5th) (tie) Motorola Moto G Stylus (2025), Motorola Edge (2025), OnePlus 13R and OnePlus 15R.
When comparing the 2025 models with the 2024 models, the improvement is modest, just one 0.78% on average. CNET recommends that, if you hesitate between a phone from last year and this year, choose the cheapest one, since the difference in autonomy will not be dramatic.
