Overall Score
- OnePlus 15 – ( 9.5/10 ) Winner
- Samsung Galaxy S25 – ( 8.4/10 )
The OnePlus 15 dominates the scoring sheet primarily due to its sheer hardware superiority. It features a significantly more powerful processor variant (Gen 5) which is reflected in its massive AnTuTu lead (3.6M vs 2.1M). In the battery category, the OnePlus is leagues ahead with a 7300 mAh cell and 120W charging, whereas Samsung’s 4000 mAh and 25W charging feel dated for a flagship. Camera-wise, the OnePlus offers a consistent high-resolution experience with three 50MP sensors, compared to Samsung’s mix of 50MP, 12MP, and 10MP.
However, ratings aren’t just about big numbers. The Samsung Galaxy S25 scores highly in display quality relative to its size and builds trust with its 7-year update promise. While it loses the “Value for Money” battle against the specs-heavy OnePlus, it remains a premium choice for users who prefer a phone that fits easily in the hand. Ultimately, for the price, the OnePlus 15 delivers substantially more technology per rupee.
