Oppo’s new charging tech decreases battery capacity at a concerning rate
- Oppoâ€™s 125W charging technology can reduce your battery capacity to 80% in slightly over two years.
- Thatâ€™s significantly more degradation than with 65W tech.
Oppoâ€™s 125W Flash Charge may be great if you want to top up your phone in a hurry, but that performance could come at the cost of long-term battery life.
The company noted that the battery capacity is â€œmaintainedâ€� at 80% after 800 full charge and discharge cycles at 125W. In other words, you may lose a fifth of your capacity in just over two years if you completely drain your battery every day. Youâ€™ll realistically last longer if you still have some charge left at the end of each day, but thereâ€™s chance youâ€™ll notice the effect. Of course, lighter users will take longer to reach that 800-cycle mark.
Either way, Oppoâ€™s new tech degrades batteries faster than weâ€™ve previously seen.
This appears to be significantly worse than with earlier wired charging tech. Oppo previously reportedÂ that its 65W charging reduced a batteryâ€™s capacity to about 91 percent after 800 cycles. Thatâ€™s still significant, but might not have a tangible effect during the useful lifespan of your device.
This doesnâ€™t come as a complete surprise. High-power charging puts added strain on a battery, and Oppo had to adopt a higher-quality battery design that could handle the whopping 12.5A of current from the 125W charger. It does, however, suggest that existing fast-charge technology may be reaching its limits.
This isnâ€™t the only new fast charging option, thankfully. Oppo is also offering 50W and 110W mini-chargers that shouldnâ€™t affect your battery as much. Also, the full charging speed only applies to phones compatible with Oppoâ€™s technology â€” other devices will last longer if youâ€™re using more universal formats like USB Power Delivery or Qualcommâ€™s Quick Charge. And if youâ€™d rather minimize recharging in the first place, there are always battery saver apps to make the most of your device.
