The 25W Standard for the Base Model: A Practical Compromise
The rumor that the base Galaxy S22 will stick with 25W wired charging is significant. This is the same speed found in the Galaxy S21, and while it may seem modest in the current market, it is far from slow. A 25W charger can typically take a 4,000mAh battery from 0 to 50% in around 30 minutes, which is a substantial improvement over traditional 10W or 15W chargers. For the target audience of the standard S22—users who want a powerful, pocketable Android flagship—this level of charging is more than adequate for daily top-ups.
By keeping the S22 at 25W, Samsung makes a deliberate choice. It ensures that the device remains accessible in terms of price and thermal management. Faster charging generates more heat, requiring more sophisticated cooling solutions and potentially impacting long-term battery health. By capping the base model at 25W, Samsung can focus on other areas of improvement, such as the processor efficiency and display technology, without pushing the thermal envelope of a smaller chassis. We believe this is a calculated decision to maintain the integrity of the user experience across the board, ensuring that even the entry-level flagship performs reliably without compromise.
The 45W Advantage for S22 Plus and S22 Ultra: Power for the Power User
For the Galaxy S22 Plus and the S22 Ultra, the shift to 45W fast charging marks a crucial upgrade. The S21 Ultra was officially rated for 25W, despite rumors of 45W support that never fully materialized due to thermal constraints. For the S22 Ultra, Samsung appears ready to deliver on that promise. A 45W charger represents a near-doubling of power delivery, which could translate to a 0-to-100% charge time of approximately 60 minutes for a larger ~5,000mAh battery, compared to the 70+ minutes required for 25W charging.
This enhanced speed is critical for the Ultra model’s pro-grade features. The S22 Ultra is expected to be a powerhouse, potentially housing the most advanced camera system in the lineup, a brilliant 120Hz Dynamic AMOLED 2X display, and the integrated S Pen. These features draw significant power, especially during extended camera sessions or note-taking. The ability to quickly replenish the battery with 45W charging means less downtime and more productivity. Furthermore, the S22 Plus, with its larger screen and battery compared to the base model, will also benefit immensely from this faster charging, bridging the gap between the standard S22 and the Ultra in terms of raw utility.
