Don't buy the phone with the biggest battery; you'll regret it, and I know this from experience.
In the age of smartphones, when running out of battery can ruin all your plans, charging speed is now more important than battery life and energy storage capacity. We'll tell you more about why fast charging is so beneficial.
While manufacturers compete to offer the highest battery capacity (mAh), the real value for the user lies in the ability to charge a phone in minutes. Below, we explore four reasons why fast charging is far more valuable than simply having a larger battery.
Reasons why fast charging is better than a large battery capacity
- First reason
One of the main reasons is that a few minutes of fast charging can restore hours of use, avoiding the long wait at the outlet for a large battery that takes hours to recharge. User perceptions change when a 10-minute charge guarantees half a day's battery life, making a fast charger a true lifesaver. Furthermore, models equipped with 45W charging significantly reduce the need to constantly wait for a power outlet.
- The second reason
Another reason is design and ergonomics, which also play a crucial role today. Every additional 1000 mAh adds about 5-10 grams of weight and makes the device thicker, hindering comfortable handling. For example, the Samsung Galaxy M51, with its 7000 mAh battery, weighs 213 grams and is 9.5 mm thick, far from being as lightweight as some of the most compact phones. In contrast, a 4500 mAh phone with 65W fast charging maintains a weight of around 185 grams and a thickness of less than 8 mm without sacrificing battery life thanks to its all-day fast charging capabilities.
- The third reason
Advances in charging technology have boosted available power: Realme unveiled a 320W charger in 2024 capable of charging a 5,000mAh device in just 5 minutes and a 240W charger in a single, compact unit. This trend is leading the way: manufacturers like OnePlus, Xiaomi, and Oppo are already equipping many of their phones with 80W to 150W chargers, reducing standby time without resorting to bulky batteries that would increase costs and size.
- The fourth reason
The fourth reason relates to battery health. Fast charging is ideally regulated using thermal control chips and protection algorithms that prevent overheating and overcharging. Studies indicate that the accelerated battery degradation caused by fast charging is minimal when using official chargers with integrated thermal management. Although excessive and improper charging can generate internal heat, various tests have shown that modern systems automatically shut off power when the battery reaches 100%, reducing the risk of chemical damage and ensuring that your phone can benefit from fast charging as safely as possible thanks to recent technological advancements.
