1. Unlocking the Benefits of Rapid Charging on Smartphones
The rapid charging technology on smartphones brings numerous advantages to users while also boosting competition among brands in the mid-range segment.
The battery has been the slowest progressing component on smartphones over the past decade. Smartphones are incorporating more features, with the number of integrated camera sensors increasing, yet battery technology lacks breakthroughs. Manufacturers face the challenge of larger battery capacities resulting in longer charging times, impacting user experience.
'In 2012, fast charging technology was a luxury, and I encountered many inconvenient situations while traveling for work. I had to seize every lunch break or coffee break to charge my phone because I used it extensively, and the battery drained quickly, especially with constant movement. At the airport, people queued for long periods to charge their phones due to limited power outlets, which was truly inconvenient,' shared Mr. Duc Trung, a moderator on the tinhte.vn forum, during the Technology Roundtable - RealMe RealTalk program.
Fast charging technology is highly praised by many experts for its significant value in enhancing user experience.
Due to the high costs involved in research, manufacturing, and integrating technology, fast charging has become a feature almost exclusively reserved for high-end smartphones.
'In 2014, Oppo introduced the Find 7 with VOOC technology, enabling a 70-75% battery charge in just 30 minutes. Since then, fast charging technology has gained more attention. Many subsequent phone models have integrated their own fast charging technology, mainly based on the principles of VOOC fast charging and Qualcomm's processor platform,' added Mr. Duc Trung.
At that time, a 3,000 mAh battery capacity was considered large, with an average full charging time of 2 hours. However, with VOOC fast charging, users only need 50-60 minutes.
VOOC fast charging has developed alongside other proprietary technologies... However, VOOC technology maintains a distinct position regarding its operational mechanism, ensuring low heat dissipation and increased safety.
Many fast charging technologies employ methods of pushing current and voltage to increase charger power. In contrast, VOOC utilizes a fixed 5 V voltage and enhances current intensity. With high current intensity, the charging cable is specially designed with a 7-pin connector instead of the standard 5-pin connector. The cable size is thicker and larger to accommodate the high current flow. Oppo states that the latest VOOC 4.0 technology operates at a voltage of 5 V, current intensity of 6 A, and total power of 30 W, yet it delivers faster charging than a 40 W total power charger from another brand.
During the Technology Roundtable, Mr. Công Hậu from The Pixel YouTube channel shared: 'I appreciate Oppo - Realme's VOOC technology because it allows me to use my phone while fast charging, ensuring safety with 5 levels of protection. With other fast charging technologies, as the device temperature rises, the current protection mode reduces charging power, sometimes causing overheating.'
After years of development with various versions, VOOC fast charging is gradually being integrated into mid-range smartphones. The Realme 6 is the first smartphone model to feature VOOC 4.0 fast charging, with a power of 30 W in the sub-6 million VND segment.
VOOC 4.0 is the latest fast charging technology, an upgrade from VOOC 3.0, equipped on Realme 6 and Realme 6 Pro. In terms of power, VOOC 4.0 has been increased to 30 W (5 V/6 A) instead of 20 W (5 V/4 A) on VOOC 3.0, resulting in a 12% faster charging speed. Using VOOC 4.0, Realme 6/6 Pro takes 62 minutes to fully charge a 4,300 mAh battery, maintaining a temperature of 35-36 degrees Celsius, as announced by the company.
VOOC 4.0 charging incorporates the VFC algorithm to optimize the charging process, providing high power and minimizing charging time. Even gaming while charging does not lead to device overheating.
