Bigger 500mAh Battery Confirmed in FCC Filing
The Amazfit Active 3 Premium smartwatch is making headlines once again. After being spotted in the backend code of the Zepp app version 10.0.5, the upcoming wearable has now surfaced in an official FCC filing, revealing key specifications — including a significantly larger 500mAh battery.
Although Amazfit has not yet made a formal announcement, these leaks strongly suggest that the Active 3 Premium is nearing launch. With upgraded battery capacity, Bluetooth 5.3 support, and signs of a global release, the smartwatch could become one of the brand’s most competitive models in 2025.
Let’s break down everything we know so far.
FCC Filing Confirms Model Number and Battery Upgrade
The Federal Communications Commission (FCC) listing identifies the device under model number A2559. The documentation includes a packaging sketch clearly displaying the name “Amazfit Active 3 Premium.”
One of the most important details revealed in the filing is the battery capacity:
- 500mAh battery
This is a major upgrade compared to some of its predecessors.
How It Compares to Other Amazfit Models
To understand the significance of this upgrade:
- Amazfit Active 2 (Round & Premium 2025 models) – 270mAh battery
- Up to 10 days of typical use
- Amazfit Active Max – 658mAh battery
- Up to 25 days of battery life
- Amazfit Active 3 Premium (leaked) – 500mAh battery
With nearly double the battery capacity of the Active 2, the Active 3 Premium could potentially offer significantly extended battery life, possibly in the 14–20 day range depending on usage.
Battery life remains one of the most searched features in the smartwatch market, and this upgrade could make the Active 3 Premium highly attractive to users who prioritize long-lasting performance.
Bluetooth 5.3 Support: Improved Connectivity
The FCC documents also confirm support for Bluetooth 5.3, the latest low-energy wireless standard.
Bluetooth 5.3 offers:
- Improved energy efficiency
- More stable device connections
- Faster data transfer
- Reduced signal interference
For users, this means better syncing with smartphones, smoother notifications, and more reliable pairing with wireless earbuds or fitness equipment.
Signs of a Global Release
The packaging sketch included in the FCC filing shows multiple languages and certification marks. This strongly suggests that Amazfit is preparing for a global launch, not just a limited regional release.
As with previous Amazfit smartwatches, the box is expected to include:
- The Amazfit Active 3 Premium smartwatch
- A standard watch strap
- A magnetic charging puck
Amazfit typically maintains consistency in packaging, so users can expect a familiar unboxing experience.
What This Means for Amazfit’s 2025 Lineup
Amazfit has been expanding its smartwatch portfolio aggressively, targeting both fitness enthusiasts and everyday users.
With the recent release of the Active Max and updates to the Active 2 series, the Active 3 Premium appears positioned as a balanced mid-to-premium offering — combining:
- Strong battery life
- Modern connectivity
- Likely advanced health tracking features
- Competitive pricing
Given Amazfit’s history, we can reasonably expect features such as:
- Heart rate monitoring
- SpO2 tracking
- Sleep tracking
- Stress monitoring
- Multiple sports modes
- AMOLED display
- Water resistance
While these specs haven’t been officially confirmed yet, they align with Amazfit’s current smartwatch ecosystem.
Why Battery Life Matters More Than Ever
In today’s smartwatch market, battery life has become a key differentiator. While competitors like Apple and Samsung focus on app ecosystems and advanced software features, Amazfit has built a reputation around long battery endurance.
A 500mAh battery suggests Amazfit is continuing to prioritize:
- Fewer charging interruptions
- Extended outdoor activity tracking
- Reliable travel performance
- Consistent fitness monitoring
For users who dislike charging devices daily, this could be a major selling point.
Expected Release Timeline
Although Amazfit has not confirmed a launch date, multiple leaks in a short period typically signal an upcoming release. Many industry watchers expect the Amazfit Active 3 Premium smartwatch to launch within the next few months.
FCC certification is usually one of the final steps before a product enters the market, making a near-term announcement highly likely.
Final Thoughts: A Promising Smartwatch Upgrade
The Amazfit Active 3 Premium leak paints a promising picture. With a 500mAh battery, Bluetooth 5.3 connectivity, and signs of a worldwide rollout, the smartwatch appears ready to compete strongly in the mid-range wearable market.
If Amazfit combines this larger battery with its proven fitness tracking technology and competitive pricing strategy, the Active 3 Premium could become one of the most searched and best-selling smartwatches of 2025.
Now, all eyes are on Amazfit for the official announcement.
