ASDAWN for Samsung Gear Fit 2 Pro Battery Replacement (Large)

In this review the focus is on the ASDAWN replacement battery for the Samsung Gear Fit 2 Pro SM-R365, aimed at owners who need to restore reliable run time without replacing the whole watch. The bottom line: this is a straightforward, cost-effective replacement battery that matches OEM performance claims, offers about 200mAh capacity and safety protections, and is best for people comfortable opening a fitness watch or who can follow repair guidance. It is not suitable for the smaller Gear Fit 2 SM-R360 or other models, so verify the watch model before you buy.

Key Features

• Model compatibility: Specifically compatible with the Samsung Gear Fit 2 Pro SM-R365, so buyers get a direct replacement when they confirm the old battery part number.
• 200mAh capacity: The higher-capacity Li-ion cell is intended to restore typical multi-day use and claims up to roughly 48 hours of run time under normal conditions.
• Safety tested cells: Grade A battery cells and a built-in microchip provide protection against over-charging, over-discharging, short-circuit and over-heating for safer operation.
• Performance guidance: ASDAWN recommends using the original charger and cycling the battery 3 to 5 full charge/discharge times to reach optimal capacity and longevity.
• Quality control and support: Items are inspected in automated workshops and the brand offers replacement or refund support plus access to professional engineers for repair questions.

Who It's For

The ASDAWN battery is best for Gear Fit 2 Pro SM-R365 owners whose watch still functions but suffers from degraded battery life and who are willing to open the device or have it replaced by a technician. It suits users who want a cost-saving alternative to buying a new watch and who will follow the charging and break-in instructions for best results.

It is not for owners of the smaller Gear Fit 2 SM-R360 or Galaxy Fit 2 SM-R220, as the product is incompatible with those models and will not fit. Also, anyone who needs a preserved waterproof warranty or plans to frequently submerge the watch should look elsewhere because the replacement voids the original waterproofing.

Pros & Cons

Pros

• Restores battery life to near-OEM performance with a 200mAh Li-ion cell and Grade A components.
• Built-in protection circuitry reduces risk of over-charge, over-discharge, short-circuit and overheating.
• Manufacturer support and clear advice on break-in charging cycles and using original chargers.

Cons

• Replacing the battery destroys the watch's original waterproof seal, limiting use around water.
• Installation requires opening the watch or a technician; not a plug-and-play external accessory.

Our Verdict

The ASDAWN replacement battery is a practical, value-oriented fix for Gear Fit 2 Pro SM-R365 owners who want to restore run time without buying a new watch.

For those constraints it represents a good compromise between cost and performance.
