how long does the oculus quest 2 battery last? (And When Should You Charge it?)
One of the best things about VR is that it has the ability to take you away from reality into a different realm that washes your troubles away; until the battery dies. So how long does the Oculus Quest battery last?
The Oculus Quest 2 is equipped with a 3540 mAH (14. Wh) lithium-ion battery, which provides around 2 to 3 hours of battery life depending on your usage. Additionally, Enabling optimal performance features such as a 120 Hz refresh rate will consume more battery than using a lower refresh rate.
Let’s dive deeper into the subject and take a look at tips to substantially increase and maintain your Oculus Quest 2’s battery capacity that you probably don’t know.
How long does the oculus quest two battery last?
Oculus Quest’s battery should last you around 2 to 3 hours, depending on how you use your device. For example, certain games are CPU intensive and will require additional power to display the visuals; this can cause your device to last around 1.5 to 2 hours. However, using your Oculus to browse the web, movies, youtube…etc. It will require less power, thus providing 2.5 to 3 hours of battery life.
However, the main factor to note here is that since Oculus Quest uses Lithium-Ion batteries, the more charge cycles your device consumes, the less battery it can hold.
Let’s dive deeper into this subject by looking at how lithium-ion batteries work; we’ll also take a look at the ideal charge cycle for optimal battery health and a prolonged battery capacity based on a few studies.
When Should You Charge Your Oculus Quest 2 For a longer Battery Life expectancy?
The first thing you will need to know is that your Oculus Quest headset battery degrades over time like any device. And just like any device, your battery health can degrade even faster without proper care.
Here are the two main reasons why you need to worry about your device Battery health; they are your battery capacity and performance factors.
Having a degraded battery capacity means that a battery that could hold 3 hours of charge may now only be able to hold 2 hours of charge.
So how do you maintain your Oculus headset’s battery health?
Your battery expectancy is dependent on three main factors; your charge cycles, the environmental temperatures you expose your device to, & the battery percentage at which you may store your device.
Let’s start with charge cycles; Lithium-ion batteries work in charge cycles; A charge cycle is when your device consumes equal to 100% of your battery capacity. Simply put, you consume one charge cycle when you go from 100% to 0%. The more charge cycles your battery consumes, the faster your battery will chemically age, resulting in diminished battery capacity and performance.
With Lithium-Ion batteries, there are two main things you need to know: The first is anytime your battery drops below 20%, you consume one charge cycle; This is because discharging below 20% puts a lot of stress on your battery and increases its temperature. The second is charging your device over 80% also adds stress to your device’s battery, thus increasing its temperature; this is why most devices are equipped with Optimized Battery Charging, which is designed to delay charging past 80%.
So now that you understand the gist of it, let’s take a look at the studies.
According to a study done by Battery University on lithium-ion batteries, the ideal charge cycle for a prolonged battery life span is 75% to 25%; this charge cycle had the best results in the long run when it comes to maintaining battery capacity and battery performance.
Alternatively, the study shows a charge cycle from 100–25% Has a significantly shorter lifespan.
The best overall is a 75–65% charge cycle which offers the longest cycle life, but since this is only a 10% battery capacity, it’s not a sustainable or practical charge cycle.
Enviromental Tempratures & Storage
The second and third factors that impact your Oculus’s battery health are environmental temperatures and the battery percentage you store your device at.
Lithium-Ion batteries don’t perform well in extreme temperatures, whether it’s too hot or too cold. This increases stress on the battery causing it to chemically age.
Additionally, maintaining a high battery percentage while stored also adds additional stress to our device’s battery as it cause its temperature to rise.
Battery university shows the impact of battery deterioration in extreme temperatures & how the battery percentage of your stored device can have a massive impact on maintaining your device’s battery health.
The study shows that when a device is stored at 100% battery. After three months of storing that device at 100% battery at 40°C, it will only retain 65% of its battery capacity. However, if the device is stored at 40% battery at 40°C, it will retain 75% of its battery capacity.
How long does it take to charge the Oculus Quest 2?
With the provided Oculus Quest charger, it should take you around 2 to 2.5 hours to fully charge your Oculus Quest headset.
Can I charge oculus quest 2 overnight?
Charging your Oculus Quest 2 overnight will not lead to overcharging; since the Oculus Quest features a Lithium-Ion battery, the device will automatically stop charging once it reaches 100% battery. So leaving the charger plugged in for an extended period of time has no impact on the battery health whatsoever.
Can you use the Oculus Quest 2 whilst charging?
Yes, you can charge and use your Oculus Quest 2 at the same time. However, you will notice that with certain games, your device will nearly charge since it requires additional power.
If you’d like to charge your device with Oculus Link, then you will need an Oculus Link cable since it offers Dual-function support meaning it can connect your headset to your PC while charging your device at the same time.
How do you make the oculus 2 battery last longer?
The only way to make your Oculus headset last longer is by purchasing a battery strap. Oculus sells their own Elite strap, which adds an additional 2 to 2.5 hours of playtime as well as provides a more comfortable fit and enhanced adjustment features. However, the only downside is that it’s currently priced at $109.
Alternatively, you can use third-party battery packs as well as power banks; however, you need to ensure they meet Oculus’s requirements.
