When DJI unveiled the Osmo Pocket 4, the headline-grabbing specs were impossible to miss: 4K slow-motion at a buttery 240fps, a class-leading 14-stop dynamic range, and yet another refinement of its signature gimbal-stabilized design. But after spending time with the spec sheet and watching real-world tests, a quieter upgrade has emerged as perhaps the most practical game-changer for creators on the go.
We’re talking about battery life.
While the internal cell only saw a modest capacity increase – from the Pocket 3’s 1,300 mAh to 1,545 mAh on the new model – the real-world endurance tells a very different story. Something far more efficient is happening under the hood, and YouTuber MountMedia decided to put both cameras head-to-head in a side-by-side recording marathon. The results? Genuinely surprising.
The Numbers Don’t Lie: Pocket 4 vs Pocket 3 Recording Times
MountMedia ran the two gimbal cameras through a series of standard shooting scenarios, testing at different resolutions and frame rates. Here’s how the Osmo Pocket 4 stacked up against its predecessor:
| Resolution | Osmo Pocket 4 (1,545 mAh) | Osmo Pocket 3 (1,300 mAh) | Improvement |
|---|---|---|---|
| 1080p/24fps | 4h 00m | 2h 47m | +73 min (+44%) |
| 4K/30fps | 3h 24m | 2h 02m | +82 min (+67%) |
| 4K/60fps | 2h 24m | 1h 54m | +30 min (+26%) |
Yes, you’re reading that correctly. At the ever-popular 4K/30fps, the Osmo Pocket 4 lasted 3 hours and 24 minutes – a whopping 67% increase over the Pocket 3’s 2 hours and 2 minutes. That’s nearly an hour and a half of extra shooting time from a battery that’s only 19% larger in capacity.
Even at the more demanding 4K/60fps, the newer camera stretched its lead to 2 hours and 24 minutes, compared to the Pocket 3’s 1 hour and 54 minutes. That’s a 26% gain, which means you can capture high-frame-rate action sequences without anxiously watching that battery icon tick down.
Casual Shooting? The Pocket 4 Almost Lasts Half a Day
DJI’s own lab-tested figures paint an even rosier picture for vloggers and run-and-gun filmmakers who primarily shoot in 1080p. In a controlled environment at 1080p/24fps, the Osmo Pocket 4 is rated for a staggering 4 hours of continuous recording. That’s 1 hour and 13 minutes longer than the Pocket 3’s 2 hours and 47 minutes.
For context, that’s enough to film an entire indie feature’s B-roll, a full day of travel vlogging across multiple city stops, or a live event from start to finish without scrambling for a power bank.
What’s Driving the Efficiency Leap?
The modest battery capacity bump suggests DJI has made significant strides in processor efficiency. The Pocket 4 likely benefits from a more advanced image signal processor (ISP) and optimised firmware that reduces power draw during encoding, gimbal stabilisation, and wireless transmission. It’s a classic example of hardware and software working in harmony – you get more recording time without lugging around a thicker, heavier camera.
Of course, your mileage may vary. Real-world recording times depend on several factors:
- Gimbal activity – Constant panning, tilting, and following modes consume extra power.
- Screen brightness – Cranking the built-in display to max will shave off minutes.
- Magnetic fill light – The new accessory is handy for low-light shots, but it draws from the same battery.
- Wireless connectivity – Keeping Wi-Fi or Bluetooth active for remote monitoring adds drain.
That said, the delta between the two generations remains impressive even under heavy use. For most creators, the Pocket 4 is finally approaching that elusive “full-day camera” status – no battery handle required (though DJI still sells one if you’re planning an all-nighter).
Charging Speed: No Surprises (But That’s a Good Thing)
If you were hoping for faster top-ups, the news is neutral – which isn’t necessarily bad. Both the Pocket 3 and Pocket 4 charge at identical speeds when paired with a 65W PD charger:
- 0% to 80%: 16–18 minutes
- 0% to 100%: 32 minutes
That means even if you do manage to drain the Pocket 4’s larger effective capacity, you can get back to 80% in the time it takes to grab a coffee. The fact that DJI didn’t slow down charging despite the efficiency gains is a win.
Why This Matters for Creators
Let’s be honest – the Osmo Pocket series has always been about balancing portability with pro-level features. The Pocket 3 was no slouch, but its battery life often left vloggers and travellers tethered to external power banks or the optional grip. The Pocket 4 changes that equation.
Imagine filming a wedding ceremony, a hiking trail time-lapse, or a multi-hour interview without constantly checking your remaining time. Or think about travel creators who move through crowded markets and transit systems – every extra minute of untethered recording is one less cable to fumble with.

See the Test for Yourself
Numbers are one thing, but watching the battery bars drain in real time is another. MountMedia’s full side-by-side test is embedded below – it’s well worth a watch if you’re trying to decide whether the Pocket 4 is worth the upgrade.

In the video, you’ll see the Pocket 3 tap out while the Pocket 4 keeps rolling – sometimes for over an hour longer. It’s the kind of practical, no-nonsense comparison that cuts through marketing hype.
Final Verdict: The Silent Upgrade That Steals the Show
The DJI Osmo Pocket 4 is undeniably a technical powerhouse – 4K/240fps slow-motion and 14 stops of dynamic range are nothing to sneeze at. But for everyday creators who actually use these cameras in the field, the battery life improvement is the real headline.
With up to 67% longer recording times at 4K/30fps and a whopping 4 hours at 1080p/24fps, DJI has addressed one of the Pocket 3’s few genuine weaknesses. You’re getting a camera that lasts longer, charges just as fast, and fits in the same pocket-friendly form factor.
Whether you’re a daily vlogger, a travel documentarian, or just someone who hates hunting for outlets mid-shoot, the Osmo Pocket 4’s under-the-radar battery upgrade might be the feature you’ll appreciate most.
