OnePlus 11 vs Samsung Galaxy S23 Ultra: Which Phone Wins The ‘Battery Performance’ battle

2023 is off to an excellent start for smartphone lovers, as we already have two flagship smartphones from Samsung and OnePlus. The OnePlus 11 and Galaxy S23 Ultra are the latest top-end models to hit the consumer platform.

OnePlus 11 and Galaxy S23 Ultra are the latest flagships that have finally excelled in battery performance. Yet at some point, the OnePlus flagship Galaxy S23 Ultra wins with the ability to charge the smartphone, and the performance deserves praise. 

Battery life and charging:

 Both devices are known for their amazing features and specifications, with the OnePlus 11 charging capability surprisingly higher than the Galaxy gadget. OnePlus 11 and Galaxy S23 Ultra pack a 5000mAh battery for excellent battery life. With the increased efficiency of the Snapdragon 8 Gen 2 and its larger battery, you can expect two days of regular usage. 

Samsung’s device can charge using a 45W wired charger or 15W wireless charging. It also has the capability of reverse wireless charging. Whereas, OnePlus completely skipped wireless charging this year but includes an 80W SuperVOOC power adapter (100W internationally). 

Moving on, it can charge the OnePlus 11 in a jiffy. It takes about 30 minutes to go from dead to full power. While the Galaxy S23 Ultra 45W fast charger charges up to 68% in 30 minutes. So with charging capabilities like these, we can say that the OnePlus 11 has won the ‘battery performance’ battle with the Galaxy S23.
