I stopped focusing on battery capacity after learning what actually drives Android fast charging

For weeks after acquiring the Google Pixel 8, the reporter found it struggled to reach full charge on various chargers. The device demanded attention to battery life, which was subpar. The phone featured a 4,575 mAh battery, supporting up to 27W wired charging. The battery capacity appeared small compared to devices with 6,000 mAh cells, but the reporter understood it was slower due to communication between the charger and the phone.

The sweet spot for fast charging was between 20% and 80%. Using a 65W adapter and a 240W cable, the reporter achieved an 18-minute charge from 56% to 80%. However, the final 12% took an additional 18 minutes, with the first 8% taking only four minutes. Near full capacity, the charging speed declined significantly. Algorithmic safeguards, such as Google's battery protection and thermal management, contributed to the slowdown.

Charger manufacturers also complicated the process by creating their own fast-charging modes, which could impact charging speed. The reporter emphasized the importance of cooling the device while charging and unplugging around 80%. The reporter also highlighted that a $100 charger may not always be the best choice, as it may offer features not needed for the phone's actual charging requirements. The reporter used a 65W Yesido GaN charger for months, which worked well with the Pixel 8.
