What OnePlus Announced and Why It Stands Out
OnePlus has introduced a new smartphone accessory called the Magnetic Ice Cooling Clip alongside the OnePlus 15T, positioning it as the world’s thinnest magnetic phone cooler. The headline claim is its thickness: it measures just 9.8mm at its thinnest point, which is unusually slim for an active cooling accessory.
Phone coolers are becoming more relevant because modern phones generate more heat during gaming, video recording, and long streaming sessions. When a phone heats up, performance can drop due to thermal throttling, and the device can feel uncomfortable to hold. A thin cooler targets a simple user need: better sustained performance without carrying a bulky accessory.
OnePlus has priced the cooler at $26, and the company is emphasising portability by saying it can fit in a pocket even when attached. That combination—thin build plus lower pricing—suggests OnePlus wants this to be a mass-market add-on rather than a niche esports gadget.
Design and Build: Size, Weight, and Magnetic Hold
The Magnetic Ice Cooling Clip uses a compact, power bank-like design. It measures 87.6 x 62mm, with 9.8mm thickness at the thinnest point and up to 11.9mm in thicker areas. The unit weighs 68 grams.
In everyday use, weight and thickness matter as much as cooling power. A heavy cooler can make a phone feel unbalanced, especially during long gaming sessions. A thin profile can also reduce the “bump” effect that makes some coolers awkward to hold or hard to fit into a pocket.
OnePlus says the body uses PC and aluminum alloy materials and includes an indicator light system. Materials choice matters for heat transfer and durability. Metal parts can help spread heat, while plastic sections can reduce weight and make the device more comfortable to touch.
Attachment is magnetic, with a claimed holding force of up to 10N. The practical point here is stability: a secure hold reduces slipping during gameplay and keeps the cooling plate aligned with the phone’s hottest area, which is usually near the chipset.
Cooling Hardware: TEC Module, Air Duct, and Two Modes
The core cooling system combines a thermoelectric cooling (TEC) module with a curved progressive air duct and a pressurised low-noise centrifugal fan. TEC cooling is commonly used in phone coolers because it can actively pull heat away from the contact area rather than only moving air around the phone.
OnePlus describes the airflow path as top intake and side exhaust. That design matters for comfort. If hot air is pushed directly toward the user’s fingers, the cooler can feel unpleasant during long sessions. By expelling hot air from the side, OnePlus is aiming to keep the hand zone more comfortable.
The cooler supports two modes. Silent mode is positioned for lighter tasks like streaming and photography, where you want less fan noise. Performance mode is designed for maximum cooling during gaming and heavy workloads, where sustained performance is the priority.
Noise ratings are listed at 22dB in silent mode and 36dB in performance mode. In simple terms, silent mode aims to stay subtle in a quiet room, while performance mode may be more noticeable but should deliver stronger cooling when the phone is under stress.
Compatibility, Power, and Controls: Android, iPhone, and Bluetooth
OnePlus says the Magnetic Ice Cooling Clip supports both Android and iPhone devices through its magnetic attachment system. That cross-platform approach is important because many cooling accessories are built around one ecosystem, but a magnetic solution can be used across devices if the phone supports magnetic mounting or uses a compatible case.
The cooler also includes Bluetooth connectivity, which allows settings adjustment through ColorOS X mode. This indicates OnePlus wants users to treat it like a smart accessory rather than a simple on/off fan. Bluetooth control can make it easier to switch modes, monitor status through lights or app controls, and tune performance depending on what you are doing.
Power is delivered through USB Type-C with a maximum input of 5V/3A. That is a common power profile for phone accessories and suggests it can run from a charger, a power bank, or a compatible USB-C port. Because active cooling draws continuous power, the main practical consideration for users is how they plan to power it during long sessions—especially if they also want to charge the phone at the same time.
Overall, the Magnetic Ice Cooling Clip is aimed at a simple problem: heat. By focusing on a thin body, a TEC-based cooling approach, and flexible compatibility, OnePlus is trying to make phone cooling easier to adopt for normal users, not only hardcore gamers.
