Battery capacity, battery life and charging time of the Oculus Quest 2

Oculus Quest 2 battery life

Some articles in the blog are simply created because I was interested in certain things myself and I would like to summarize the information I found in one place. So also this article, which contains all information about the battery of the Oculus Quest 2 - also a few tips on a power bank or at least on the power bank capacity, which I would recommend if you want to have longer fun with your Quest 2.

Quest 2 battery data in detail

Battery life and charging time of the Quest 2 VR glasses

In order to get practical values ​​for the running time and the loading time of Quest 2, you only have to try Google briefly and you will find the following information very quickly:

  • Battery life: approx. 2 hours (depending on the game, sometimes up to 3 hours)
  • Consumption: approx. 5,6 watts
  • Charging time: about 2,5 hours
  • Charging socket: USB-C

I left out the controller of the quest here. These are fitted with standard AA batteries and can easily last 100 or more hours.

Which charging cable can I use for the Oculus Quest 2?

The Quest 2 is charged via a USB Type C port. However, the charging voltage is only 5 volts (no USB PD). Because of this, you can have both USB-C cable one that has a USB-A connector on the other end, as well as one that has a USB Type-C connector on both ends. I would recommend a straight but angled USB-C cable and then use a matching power adapter with it.

Why an angled cable? Because you can then run the cable along the head mount if you want to play with the power bank in your pocket while the Quest 2 is charging. I find the set of 2 by Ugreen or the 1,5m cable from ULT-WIIQ good, but you can too rummage here at Amazon and see what suits you. But pay attention to the length, because it should be 1 to 1,5 m. For me (1,88 cm height) the 1 meter cable is just too short so that it is tense when I turn my head to the side.

Power bank recommendation for Quest 2

I only had one a few days ago Intenso Powerbank with 5000 mAh bought to use it to load Quest 2 while playing. This is also practical because it has an input and output with a USB-C port, but unfortunately 5000 mAh is just enough to fill the Quest 2 to a quarter when it is almost empty and you can use the Powerbank is charging.

Update: Don't play and charge, just plug in the power bank beforehand!

Today I plugged the Quest 2 fully charged into the power bank and then played and I was able to gamble for about two hours until the power bank was empty and the internal battery of the Quest 2 was tapped. Seen in this way, the Intenso power bank is a practical little thing that can be recommended. Update end.

If you want a decent gain in playing time, you should consider a power bank with 10.000 or even 20.000 mAh. A flat design is also an advantage so that the power bank fits in your pocket and, last but not least, I would rely on a power bank that has a USB C port, through which you can both draw power and feed it in for charging.

The Intenso power bank with 5000 mAh is nice and small and brings about 2 hours more playing time if you plug it into a freshly charged Quest 2 (Photo: Sir Apfelot).

So here are my power bank recommendations ...

For about 2 hours more playing time:

If you want to add more than 4 hours to the Quest 2 runtime, you will find recommendations for larger power banks with 10.000 mAh and more ...

The luxury variant is certainly the Zendure Powerbank, which even supports USB C Power Delivery:

If you are looking for the good & cheap variant, you can take this here:

Incidentally, I got the Charmast with 26800 mAh because I have large pockets and have problems with the additional weight. If you want less weight, you can maybe take two 10.000 mAh batteries and plug them in one after the other.

Oculus Statement: Do not load Quest 2 while playing

There is a statement from Oculus that you should not play while the battery is being charged in Quest 2.

Do not use or wear your headset while it is connected to the AC adapter or while it is charging. ( )

The reason for this is that it can overheat. To minimize the risk, I always do it this way: I charge the Quest 2 completely and then plug in the power bank while playing. This means that the battery is kept at 100%, so to speak, which generates much less heat than actually filling it.

Battery replacement on the Oculus Quest 2

I found some interesting information on the subject. There is one at iFixit Instructionshow to disassemble the Quest 2. But that looks pretty fiddly. That is why the practical solution that has prevailed for most people is that you simply leave the old battery in the Quest 2 and instead have a power bank connected to the Quest while playing.

    Good job, good article. One of the few on this subject, so thanks.

    Sir, the math doesn't add up. I suspect that your 5000mah Intenso Powerbank actually does a little less. 5000mAh at 5V is 25 watts. How do you get only 2 hours with a device that only requires 6-7 watts? Are we to believe that there is a 50% conversion loss? That seems exaggerated to me. What do you think?

      Hi Dan! I didn't measure the time exactly and it could be that it was 1,5 hours... then it would be in the range of 70-80%, which should be there.
