I’m getting chills with the OnePlus 15T’s certified 7,500mAh Glacier battery
What you need to know
- The president of OnePlus, Li Jie Louis, confirms that the OnePlus 15T will have a large 7,500mAh battery, powered by its Glacier technology.
- The company also confirms that the device will be paired with 100W and 50W wireless charging, and users can play games while charging without generating too much heat.
- Rumors suggest that the OnePlus 15T may launch sometime in the first half of 2026.
The OnePlus 15T has been an interesting feature floating around since before the flagship 15 was launched last October, but the company has now confirmed a major upgrade.
On the Chinese social network, Weibo, the president of OnePlus, Li Jie Louis, announced that the OnePlus 15T will sport a major battery upgrade (via GSMArena). Their post confirms that the next compact phone will have a massive 7,500mAh battery at launch. Li Jie Louis adds that the purpose of this development is due to user feedback.
As mentioned before, the OnePlus 15T is a “compact” phone with a (alleged) 6.3-inch display. According to Li Jie Louis, one of the biggest complaints users have about small phones is that they often lack significant battery capacity. OnePlus confirms that the battery technology of the OnePlus 15T Glacier battery, a piece of hardware will be released in 2024 (although the capacity was much lower than this).
The post adds that the phone will be equipped with 100W wired charging and “enhanced” 50W wireless power. Li Jie Louis claims that consumers can play games and charge their phones simultaneously without generating too much heat.
The Chilling Glacier
Rumors hinted at this last year, as reports said the OnePlus 15T would have upgrades that would put its flagship counterparts to shame. Not only is Qualcomm’s latest Snapdragon 8 Elite Gen 5 rumored, but a larger battery has also been highlighted. At the time, there was no number attached to that projection; However, the OnePlus 13T was mentioned, as it had a 6,260mAh battery.
That capacity beats the flagship 13 by 260mAh. Li Jie Louis talks about the OnePlus 15T battery powered by its Glacier technology, which the company first released in 2024. OnePlus says its Glacier batteries are built on a “silicon carbon anode” to greatly improve the charge (capacity) its batteries can hold. The Swift 100W wired charging was promised by its Glacier chargers, and the claim that it will retain 80% of its life after four years.
The OnePlus 15T is expected to launch this year, possibly during the first half of 2026.
Android Central Take
OnePlus is bringing the battery capacity I know I’d like to see in my current flagship—and it’s an Ultra. I understand why OnePlus’ response drove them to make this kind of improvement. I’ve used small, compact phones before—mid-range devices—and their batteries were always good. You probably attach your phone to the bill more times than you would like. This is flagship quality in a compact phone, which feels like a win. Plus, I’ve been playing on my phone a lot (just because I can) and it generates heat whenever I want to plug it in. What does OnePlus say about its 15T? I’ll take that any day.
