Oppo details how it doubled the Find X5 Pro’s battery life

Written by admin

THE Oppo published this week how it managed to achieve the number of 1,600 battery recharge cycles – double the industry average of 800 cycles – with the launch of Oppo Find X5 Pro.

Announced at the end of February, the manufacturer’s high-end mobile phone combines advanced algorithms, developed over 3 years of studies, with ingenious technology implemented in the battery cells to ensure greater durability.

Oppo explains the Find X5 Pro’s double battery life

Oppo’s most powerful smartphone, the Find X5 Pro stands out not only for its powerful hardware, with Snapdragon 8 Gen 1 and MariSilicon X chip dedicated to camerasas well as the battery: the phone has a 5,000 mAh tank, with 80 W fast charging and 30 W wireless fast charging.

Such high numbers still raise doubts about the durability of the smartphone’s power system, but the giant includes a bold promise with the launch of the flagship, guaranteeing that the device would retain 80% of its battery capacity even after 1,600 recharge cycles.

This is double the industry average, normally set at around 800 cycles.

To achieve this milestone, the company has developed the so-called Battery Health Engine, which brings together two technologies designed over 3 years.

The first is the Smart Battery Health Algorithm, an intelligent algorithm that assesses the electrical potential of the negative electrodes present in the battery in real time. Its function is to maintain recharging electric current at values ​​that reduce the incidence of lithium death while maintaining high speeds.

As Oppo explains, dead lithium, resulting from excessive current or charging time beyond 100%, is primarily responsible for reducing battery capacity over time.

The Smart Battery Health algorithm prevents this risk while adapting to ensure an even longer life.

Battery that regenerates with charging

With the dead lithium issues resolved, the company then embarked on the development of the second part of the battery health engine – battery healing technology.

As the name suggests, this is a technology that regenerates damaged parts of the battery as the charging process progresses. The mechanism takes advantage of adjustments to the chemical composition of the power cell.

Very briefly, a battery provides electricity by allowing electrically charged atoms (ions) to move from the positive pole (cathode) to the negative pole (anode). The medium through which the ions travel is a chemical solution called an electrolyte, where Oppo’s technology has been implemented.

The company has developed a solid electrolyte in film form, with a new, more stable and durable formula, calling it Solid Electrolyte Interface (SEI), or Solid Electrolyte Interface.

SEI is formed by reacting with a chemical compound – a polar solvent – which regenerates the structure as ions move from cathodes to anodes and vice versa. In practice, this means longer battery life, which thus reaches 1,600 charge cycles.

In addition to Oppo mobile phones, the Battery Health Engine is also expected to be used in 150W and 160W charging systems across the entire BBK Electronics group, including OnePlus, with OnePlus Nord 3really, with Realme GT Neo 3and more versions to come.
