WHOOP 4.0 Battery Life – Is 4–5 Days Enough in 2025?
Why Battery Life Matters
When it comes to wearables, battery life is one of the most important features for users. Nobody wants to charge their device every night, especially when tracking sleep and recovery. With the release of WHOOP 4.0 and now WHOOP 5.0, one of the most common questions has been: how long does the WHOOP 4.0 battery last?
WHOOP advertised 4–5 days of battery life for the 4.0 strap. But how does that hold up in 2025, and is it enough compared to alternatives like Apple Watch or Oura Ring? Let’s find out.
WHOOP 4.0 Battery Life – The Reality
- Advertised: 4–5 days on a single charge.
- Real-world average: Most users reported 3.5–4.5 days depending on strain, workouts, and usage.
- Charging style: Unique on-the-go battery pack lets you charge without removing the strap.
This means WHOOP 4.0 was designed to minimize downtime—you could charge while wearing it, ensuring 24/7 tracking without gaps.
WHOOP 5.0 Battery Improvements in 2025
While WHOOP 4.0 gave solid performance, WHOOP 5.0 has improved efficiency:
- 5–6 days battery life on average.
- Faster charging with the latest battery pack.
- Same convenient wear-and-charge system.
If battery life is your main concern, upgrading to WHOOP 5.0 makes sense in 2025.
How WHOOP’s Battery Compares to Apple Watch and Oura
| Device | Battery Life | Charging Experience |
|---|---|---|
| WHOOP 4.0 | 4–5 days | On-the-go battery pack |
| WHOOP 5.0 | 5–6 days | Faster charging, same pack |
| Apple Watch Series/Ultra | 18–36 hours | Daily charging needed |
| Oura Ring Gen 3 | 5–7 days | Ring removed for charging |
Verdict: WHOOP beats Apple Watch by a wide margin in battery life, though Oura remains slightly stronger for sleep tracking uptime.
