Battery use depends on:
Shorter measurement intervals, GPS use, active route tracking, and brighter LEDs can reduce battery runtime.
How long does the battery last when its settings are optimized? Or how long on average?
Hi @KB123 - on the highest measurement frequency, the battery lasts around 12 hours. The lower the frequency is, the more the battery will last. On lower measurement intervals, it can go over a week or mote.
How long does the battery last when its settings are optimized? Or how long on average?
Hi @kimkomnb, please refer to Altairâs reply to the same question above.
Feel free to let us know if you have any other questions. Thank you.
A couple observations on battery lifeâŚ
It doesnât seem to charge past 90-91%, not sure if this is on purpose to optimize battery longevity?
When on 1 hour measurement interval and GPS on âon when trackingâ, the battery life appears to be only about 1-2 days? (Unless the 1 hour setting is not sticking somehow-- it does show as â1hâ on device in the settings)
EDIT: Confirmed the sensors are updating at the set 1 hour interval
I just charged as much as I could (91%) yesterday and a little less than 24 hours later sitting on the table without interacting with it, itâs at 34%.
Also-- is the app set up to update sensor readings on demand? Is that what it means by âUpdated XX/XX/XX, XX:XX:XXAM/PMâ? Or is it just confirming that itâs reading whatever the device last measured, at whatever interval itâs set at? (If itâs the latter, this is a little confusing for me, my first assumption is that whatever date/time it says is the date/time of the sensor readings displayed)
Hi @vlotty, according to the app, when you connect your AirGradient Go with the app via BLE (running the Go in Portable Mode), the air quality readings shown on the mobile app are synced in real-time with the AirGradient Go (depending on the set measurement interval on the Go).
However, you may see âUpdated xx Sep 2026 xx:xxâ on the mobile app, and the incremental time changes every minute. This indicates that the AirGradient Go and your phone are still actively communicating with each other, while the air quality reading shown on your mobile app remains the same, depending on the measurement interval set on the AirGradient Go.
For other questions, please let me observe my Go, and consult the team on this for an accurate answer, and I will get back to you.
Thanks!
My suggestion would be for it to say âSyncedâ instead of âUpdatedâ, as âUpdatedâ suggests the sensor readings were updated. and then maybe below another line that says âReadings updatedâ and the date/time?
And as another update to battery life, with the setting at 1 hour update interval, the battery died at about 1.5 days. (unsure exactly when because it happened while asleep)
Hi @vlotty, thank you again for your suggestions! I will report this to our mobile app developer.
By the way, regarding your update on the battery life. May I ask if the Go was connected to your phoneâs Bluetooth all the time when it was running?
Thanks!
If the Go doesnât automatically disconnect bluetooth, then perhaps it was connected the whole time? (or trying to connect)
Did not realize we needed to manually disconnect, though perhaps by default it should not stay connected?
Hi @vlotty, it should be fine to keep the connection. I just would like to know the condition that your Go was running on.
Our team discussed your reported case in our yesterdayâs meeting. We are currently trying to simulate that condition with our Go and observe its battery life in the latest firmware (1.1.2).
I repeated the battery life test, charged as full as I could (it still seems to max out at around 90% charge), the update interval is 1 hour, and made sure to disconnect from bluetooth. Looks like battery life will still be somewhere between 24-36 hours. In about 24 hours it looks like itâs down to 20-25%.
Hi @vlotty, I tested with my Go (itâs kind of a pre-production unit anyway). I got a similar result to yours. We will discuss this further and see what we can do to improve the battery life. Thank you so much for your report!
Please feel free to let us know if you have anything to share with us. Thanks!
Hi @vlotty, I hope you donât mind if I ask one more question from our team about the issue that you observed where your AirGradient Go didnât charge past 90-91%. Did you see the plug-in icon appear, but it never reached 100%? Thanks!
Hi Tai,
I received my AirGradient Go two days ago and have been testing its functions. Overall, itâs a great device, but I have encountered a few issues that I would like your help with:
Auto-Wake on Charge: When the Go is powered off and connected to a USB charger, it automatically wakes up after about 10 minutes.
Charging Limit: The battery will not charge past 92%, even after being plugged in for over 20 hours using the original USB cable and a modern 65W PD charger. I also noticed a flashing icon inside the battery indicator.
Connectivity Issues:
Initially, my iPhone 16 Pro Max (iOS 27) could not pair via Bluetooth or Wi-Fi.
After several attempts, Bluetooth connected, and Station Mode successfully connected to my local Wi-Fi router. However, the AirGradient app still cannot connect to the Go over Wi-Fi.
Sometimes I have to hard reset my iPhone just to get the app to reconnect via Bluetooth. On September 26, the Go disconnected again from Power OFF, requiring me to manually reconnect through my iPhoneâs Bluetooth settings before the app would recognize it.
Power Button Responsiveness: Occasionally, pressing the unlock button does not trigger the expected functions (ON/OFF/UNlock/Lock).
Hardware Test Discrepancy: During the hardware check, the Front LED test fails to turn the light ON (only the Touch 2 LED lights up). Is this because the front LED was removed in this hardware revision?
Question: What is the âDisplay LEDâ setting supposed to do? I tried turning it ON and OFF, but I donât see any visual change or LED turning on/off on the device.
Sometime hard to understand how to select the operation mode, if there is a details operation user manual for reference?
Could you please review these points and let me know if these are known bugs, hardware limitations, or if I need a replacement?
Thanks for your support!
I think so-- Iâm charging now and the plug-in icon is there. Will see what happens when it stops charging.
Hi @Alan_Ng, thank you so much for your feedback.
Auto-Wake on Charge: This is normal in the current firmware. The AirGradient Go will automatically wake up when the USB-C is plugged in.
Charging Limit: The issue you observe looks similar to @vlottyâs report. Please let our engineer investigate this further.
Connectivity Issues: Could you please provide us with more details on
Regarding your question about the âDisplay LEDâ, they was supposed to illuminate the display, but we ultimately decided to get rid of them. Hereâs what the âDisplay LEDâ looks like:

Please feel free to report to us if you experience any issues. Thank you!
Hi @vlotty! The engineering team wanted to know if by âbattery life testâ you meant that you fully ran the âFG Learningâ hardware test?
No, it was just by fully charging as much as I could (to about 90%, then the device stops displaying the plug/charging icon), then just seeing about when it says âbattery level criticalâ.
