What’s happening
The new Google Home Speaker has a bug that causes it to download massive amounts of data in the background, even when it’s barely being used. The issue was reported by 9to5Google on October 19, 2026, after the outlet noticed that one of its own review units had been quietly pulling data from Google’s servers around the clock.
Over the past week, several owners on Reddit reported that their Google Home Speakers appeared to be continuously downloading data. The numbers involved are striking: in one case, a speaker that had not been used for voice commands or media streaming in the previous day still consumed 17 GB of data in 24 hours. On October 13, the same speaker downloaded 41 GB in a single day, and over the past 30 days its total download has reached 132 GB.
One detail points to a likely cause. The affected speaker downloaded 9.99 GB at 3 a.m. PT — the kind of overnight window when smart home devices typically pull firmware updates. That timing suggests the device may be repeatedly attempting, and failing, to download a firmware package, then trying again in an endless loop.
Not every speaker is affected
It is not yet clear how widespread the problem is. Another lightly used Home Speaker in a different household downloaded only 2 GB over the past month, which looks entirely normal. The issue also seems limited to the new Google Home Speaker: the same household’s Nest Hubs and other Google Home and Nest devices showed no unusual downloads.
That uneven pattern is consistent with a bad firmware build or a stuck update routine affecting only some units, rather than a problem with Google’s backend services as a whole.
How to check your own speaker
If you own the new Google Home Speaker, it’s worth checking whether yours is one of the affected units. Most routers let you see per-device data usage. If you’re using Nest Wifi, you can check in the Google Home app:
- Open the Google Home app and tap the Wi-Fi tab.
- Tap Devices, then select your Google Home Speaker.
- Open the device usage graphs — you can switch between 1-day, 7-day, and 30-day views.
A healthy speaker should show modest usage when idle. If you see tens of gigabytes moving on days you barely touched the device, you’re likely affected.
Why it matters: data caps and battery-free consequences
For households with unlimited broadband, a rogue speaker is mostly a curiosity. But many internet plans in North America still have monthly data caps, and this bug can burn through them fast. As 9to5Google noted, if you have multiple Home Speakers and a limited data plan, this issue could easily breach your cap — and some owners have already run into exactly that.
The incident also lands at an awkward moment for Google. The company discontinued the Nest Mini and Nest Audio earlier this month, making the new Google Home Speaker its flagship smart speaker going forward. A launch-year bug that silently eats through data plans is not the first impression Google wants for the device that anchors its smart home lineup.
Google says a fix is rolling out
The good news is that Google has acknowledged the problem. In a statement to 9to5Google, the company confirmed the issue and said “a fix is already rolling out that should address this for users.”
If your speaker is affected, the most practical steps are to check your data usage as described above, make sure the device is left powered on and connected so it can receive the fix, and watch for a firmware update in the coming days. For owners on metered connections, it may be worth unplugging the speaker until the fix is confirmed to have landed.
This is a developing story — the rollout status of the fix and whether more units are affected will become clearer over the next week. We’ll update this article as more details emerge.
