After a release in China during October, OnePlus has finally released the global version of the OnePlus 15. And no, you didn’t miss the OnePlus 14 — in many Asian markets the number “14” is considered unlucky, so the company is jumping straight to 15 this time around.

This year, OnePlus continues to be at the forefront of battery and charging specs, with a brand new 7,300 mAh silicon-carbon (Si/C) battery, paired with 80W wired charging (100W charging with the optional OnePlus SUPERVOOC 100W Dual Ports GaN Power Adapter Lite), and 50W wireless charging.

Important note:

OnePlus has confirmed that U.S. sales of the OnePlus 15 will not begin immediately. Due to the ongoing U.S. government shutdown, the Federal Communicatio ns Commission has paused new device certifications, delaying the phone’s official approval.

The company says the OnePlus 15 has already completed all required testing at FCC-recognized labs and its certification documents are fully submitted. Once the FCC resumes processing applications, OnePlus expects approval to follow shortly.

Customers in the U.S. can register for updates at OnePlus.com/us, while Canadian buyers can purchase the phone starting today at OnePlus.com/ca_en.

Does the OnePlus 15 have better battery life?


Yes, it certainly does. The OnePlus 15 gets a substantial upgrade from the 6,000 mAh battery in the OnePlus 13, moving to a 7,300 mAh silicon-carbon pack. That’s one of the largest batteries ever fitted in a mainstream flagship phone.

The OnePlus 15 managed to score more than three hours compared to its predecessor, jumping to 10h and 44min vs 7h and 30min of estimated battery life in our Battery Score.

How much battery does the OnePlus 15 have?


It is now confirmed that the global variant also comes with a 7,300 mAh silicon-carbon (Si/C) battery, up from 6,000 mAh on the OnePlus 13. This upgrade puts it well above rivals like the Galaxy S25 Ultra (5,000 mAh) and iPhone 17 Pro Max (5,088 mAh, eSIM model), and closer to others, like the recently announced Oppo Find X9 Pro (7,500 mAh).

Does the OnePlus 15 have wireless charging?


Yes, and it’s impressively fast. The OnePlus 15 supports 50W wireless charging, the same as its predecessor, when paired with the company’s proprietary AIRVOOC charger.

That’s far quicker than what you’ll get on most other flagships. For example, Apple’s MagSafe peaks at 25W, while Samsung’s Galaxy S25 Ultra caps at 15W.

Does the OnePlus 15 have magnetic wireless charging?


Yes, but only via a compatible OnePlus 15 case.

Does the OnePlus 15 have reverse wireless charging?


Yes. The OnePlus 15 supports 10W reverse wireless charging, letting you top up accessories like earbuds or smartwatches. It also supports 5W reverse wired charging, handy for emergencies or when you want to power another device via USB-C.

What charger does the OnePlus 15 use?


The OnePlus 15 relies on the company’s SuperVOOC system and fully supports 100W wired charging. You’ll get the compatible charger and cable in the box, unlike many rivals.

To achieve top speeds, you’ll need the original charger and cable. Third-party options using standard USB Power Delivery (PD) or PPS will still work, but at lower speeds.

The phone also supports multiple fast-charging standards: UFCS, 55W PPS, 36W PD, and 36W QC, making it compatible with a broad range of high-quality USB-C chargers.

How fast does the OnePlus 15 charge?


Charging times are somewhat slower to last year's model if you use the included 80W SuperVOOC brick. That said, with the optional 100W GaN Power Adapter Lite charger the phone should take a few minutes less to completely juice up.

Even with a slower PD or PPS adapter, you’ll still get solid performance (roughly 36W, depending on the charger).

The OnePlus 15 also includes bypass charging, which powers the device directly during gaming sessions, reducing battery wear and heat buildup.

For comparison, the OnePlus 13 (the Europe version) reached 86% in 30 minutes and a full charge in 43 minutes. Due to its larger battery, the OnePlus 15 charged to 68% in 30 minutes, and it took 45 minutes to charge completely.

Wireless charging performance remains top-tier, too. The 50W AIRVOOC charger should deliver a full charge in under 90 minutes.
