Battery life and charging
Callum · Updated 3 November 2026How long your ZoomiTag lasts between charges depends mostly on how much time it spends using GPS. GPS is the biggest drain, so anything that cuts it down makes a full charge last longer.
How long a charge lasts
| How you use it | Typical battery life |
|---|---|
| Normal 5-minute updates with Home WiFi set up | Up to 21 days |
| Normal 5-minute updates, no Home WiFi | Around 14 days |
| GPS Boost on walks | Each Boost uses noticeably more than normal tracking, depending on how fast and how long |
| Lost Mode (every 5 seconds) | A full charge lasts a few hours |
Weak mobile signal also uses more battery, because the tag works harder to stay connected.
Set up Home WiFi. It's the single biggest thing you can do for battery life. While your pet is home, the tag pauses GPS completely.
Where to see the battery level
- Health tab: the battery chip at the top of your pet's Health screen shows the level, and Charging while it's on the charger. If you can't see it, swipe across the row of chips at the top.
- Daily brief: the battery level also shows on your pet's daily brief.
- Boost sheet: tap ⚡ Boost on the Track tab to see the current level before you start a Boost.
The tag reports its battery over its own mobile connection, so you don't need to be near it, or connected by Bluetooth, to see it.
Low-battery alerts
You'll get a notification when the battery drops to 20%, and a more urgent one at 10%. If a Boost is running when the battery hits 10%, it switches off automatically to save what's left.
Make sure notifications for the Zoomi app are allowed in your phone's settings, and that Low battery is switched on under Account → Notifications.
Charging
- Use the magnetic charging cable that came with your tag. Its connector has 4 pins. Other magnetic chargers can look similar but won't charge a ZoomiTag.
- Plug it into a USB wall plug or computer, then let the cable snap on to the back of the tag.
- A full charge takes about 90 minutes.
- While charging, the tag's light flashes red. It turns solid red when fully charged.
If the light doesn't come on at all, check the cable has snapped on fully with the pins lined up, and try a different plug.
Getting the most from each charge
- Set up Home WiFi.
- Use Boost for walks, rather than leaving it on all day. Pick 1 or 2 minutes if you don't need the 30-second detail.
- Save Lost Mode for emergencies, and mark your pet Found as soon as they're safe.
- Top up once a week or so, for example on the same evening each week, so it never runs low before a walk.
The tag's NFC and QR pet profile doesn't use the battery. Anyone who finds your pet can still scan it, even if the battery is flat.
