> Fitbit Ace LTE has been tested with hundreds of families and is designed to get 16+ hours of use from a full battery.

Fail. Adults struggle to recharge their devices every day and my kids certainly won't remember to. Garmin Kids watches, while drastically different in functionality and connectivity, last 12 months before a battery replacement is needed and are wildly more suitable for young kids.

Garmin Bounce[0] for kids, which is the watch which directly competes with this, has a 12-24hr battery life on LTE, although Garmin claims 2day battery.

You are absolutely right. I'm certainly not pro-Garmin here. Just anti-12 hour battery life for kids watches. It's just not compatible with the way young kids work.

Reading the comments to dcrainmaker's review, his kids' Bounces were getting 36 hours of charge whereas several commenters state they were barely getting 10 hours, certainly less than 24 hours of charge.

Seems like the energy used to keep the LTE connection up is the main problem, if all the users have the similar settings to minimize battery used by the Garmin Bounce.

If Google/Fitbit says the ACE LTE only lasts 16 hours, I'd hope their estimate is much more conservative than Garmin's and has a lot less variance. Otherwise, I can't see the ACE LTE lasting until end of school day.

I only have to charge my kid's bounce every 2 days, 2.5 days usually. I do not turn on the "Live Tracking" very often but location updates, boundary fence notifications, voice/canned messages work great.
