A phone that lasts nine years is truly a “OPPO R9s Plus Smartphone Battery life legend.” This isn’t just about a large battery; it’s a successful implementation of a cutting-edge technological ecosystem at the time. The secrets to the OPPO R9s Plus’s long battery life can be seen in the following points:
1. Hardware Foundation: A Large 4000mAh Capacity – The Foundation of OPPO R9s Plus’s Battery Life
In 2016, when most smartphones had batteries around 3000mAh, the OPPO R9s Plus went straight for a 4000mAh battery. This battery provided a solid hardware foundation for its robust battery life.
While its larger screen and more powerful processor (Snapdragon 653) increased power consumption, the improvement brought by the 4000mAh capacity far outweighed these factors, resulting in outstanding actual battery life:
The OPPO R9s Plus Smartphone Battery life can reach up to 16 hours, easily lasting a full day.
After simulating 5 hours of heavy use, the remaining battery level was still as high as 32%, far exceeding many flagship phones of the time.
2. Core Technology: VOOC Flash Charge, Eliminating Worries About Large Batteries
A large battery alone isn’t enough; slow charging can be a burden. The R9s Plus features OPPO’s renowned VOOC Flash Charge, whose core feature at the time was its “low-voltage, high-current” solution to address charging pain points.
VOOC Flash Charge’s several features fundamentally improve battery durability:
Powerful Performance: The data speaks for itself. Using a 5V/4A low-voltage, high-current solution, the OPPO R9s Plus can fully charge its 4000mAh battery in approximately 90 minutes—a true “recharging machine.”
Extremely Low Heat Generation: Crucially, compared to other high-voltage fast charging solutions, VOOC Flash Charge barely heats up the phone during charging. Heat is a primary cause of accelerated battery aging; a cool charging process is essential for extending OPPO R9s Plus Smartphone Battery life.
Play While Charging: Thanks to effective heat management, users can play games while charging without being forced to stop due to overheating, and without worrying about high temperatures damaging the battery.
Dedicated Cable: VOOC Flash Charge requires a dedicated charger and data cable.
3. Testimonial Support: Consistently Positive Reviews from Mainstream Testimonials and Real Users
Reviews from nine years ago and feedback from users still using the phone today testify to its durability.
Reviews from 2016-2017 generally considered one of the biggest highlights of the OPPO R9s Plus to be its “longOPPO R9s Plus Smartphone Battery life,” making it a standout “long-lasting device” in the market at the time. “Excellent battery life performance of the OPPO R9s Plus” is also a frequently mentioned keyword in user reviews on Pacific Computer Network.
