A new breed of batteries that will change world of smartphones
At the heart of the OnePlus 13 series lies Silicon NanoStack battery technology, which is set to change the game in mobile power. Both models pack a 6,000mAh battery, offering a significant jump from the 5,500mAh lithium-ion battery in the OnePlus 12R. The new technology allows for greater energy density, making these devices slimmer yet more powerful—a testament to OnePlus’ commitment to innovation.
What’s So Special About Silicon NanoStack Batteries?
- Higher Energy Density: Traditional batteries use graphite in the anode, which can only store a limited amount of lithium. By integrating silicon nanoparticles into the anode, the Silicon NanoStack design boosts energy storage without adding bulk. This means you get a bigger battery in a slim and ergonomic phone.
- Less Heat, More Safety: Charging can generate heat, which is a major factor in battery wear and tear. Silicon NanoStack batteries, however, generate significantly less heat during charging. This not only makes the OnePlus 13 series safer but also extends the lifespan of the batteries over time.
- Greater Durability: The layered structure of Silicon NanoStack batteries reduces mechanical stress during use, minimizing capacity loss over time. This means that even after years of use, the OnePlus 13 and 13R batteries should retain most of their original performance—a big win for those who like to hold onto their devices for the long haul.
PhoneArena OnePlus 13 Battery and Charging Test Results:
The OnePlus 13 doesn’t just sound great on paper—it performs admirably in real-world tests. During our battery life testing, the device lasted:
- 21 hours and 30 minutes in web browsing tests (with the display manually set at 200 nits), beating the Galaxy S24 Ultra and Pixel 9 Pro XL, and nearly matching the iPhone 16 Pro Max.
- Over 8 hours in 3D gaming, though it fell short compared to its main competitors.
- It excelled in video streaming, performing better than the Galaxy S24 Ultra but trailing behind the Pixel 9 Pro XL and iPhone 16 Pro Max.
These results showcase a phone that can easily keep up with heavy daily use, though our expectations for the combination of a 6,000mAh battery and a 3nm processor were a bit higher in some scenarios.
How much battery does the OnePlus 13 have?
The OnePlus 13 comes with the astonishing 6,000 mAh battery capacity, which is well above the average for modern flagship phones. This is also a 10% increase over last year's generation, which came with a still pretty large 5,400 mAh battery.
How fast does the OnePlus 13 charge?

OnePlus phones have always been known for their incredible charging speeds, and the OnePlus 13 is no exception. Here’s what you can expect:
- Wired Charging—the OnePlus 13 supports 100W wired charging, allowing it to fully charge in 43 minutes. While this is fast, it’s not quite as quick as the OnePlus 11, which took only 32 minutes for a full charge, although that's to be expected considering it had a 5000 mAh battery.
- Wireless Charging—OnePlus has introduced the AIRVOOC 50W Magnetic Charger, a new wireless charging solution that attaches magnetically to the back of the phone (similar to MagSafe on iPhones). This accessory, sold separately for $80, fully charges the phone in 65 minutes, making it the fastest wireless charging solution in the U.S.
Keep in mind that while the OnePlus 13 supports 100W fast charging, it can only go up to 80W when used in countries like the United States. That’s because of differences in power supply standards. The U.S. uses 110V sockets, which deliver 80W charging, while regions with 220V sockets, like the EU, can achieve the full 100W.
What charger does the OnePlus 13 use?

Just like with previous flagship OnePlus phones, the OnePlus 13 comes with a 80W charger inside the box. In order to utilize the full charging speed of the OnePlus 13 you need a SUPERVOOC charger, which is developed by OnePlus' sister company Oppo.
As for the wireless charging, you don't get the AIRVOOC 50W wireless charger when you buy the OnePlus 13. That one you have to purchase separately, as long as you want the 50W of wireless charging. The phone will still charge with less powerful wireless chargers, it will just be significantly slower.
