Based on reviews posted on popular review sites as well as from Nest Protect's website, Nest Protect performs very well in terms of battery performance relative to other smart smoke detector brands.
The review site trustedreviews.com gives Nest Protect excellent ratings for battery performance in a review posted on its website. From this review:
Battery life on the AA-powered model depends on usage, but it should easily see you through five years. When batteries are low, you’ll receive a notification – you won’t have to hunt around your home looking for that beeping model. Nest Protect is designed to last 10 years, after which it should be replaced; the same is true of all smoke detectors.
The review site expertreviews.co.uk gives Nest Protect excellent ratings for battery performance in a review posted on its website. From this review:
Protect is available in wired and battery powered versions - if you're building or renovating and can hide the cables a wired model makes sense, as it will save you replacing the six AA batteries in each detector. It still has three AAs which kick in should you have a power cut. Nest expects the wireless model to last up to five years between battery changes.
The review site techadvisor.co.uk gives Nest Protect excellent ratings for battery performance in a review posted on its website. Here's a brief quote from this review:
It's now on its second generation (which is slightly slimmer and curvier) and there are two versions available: mains- or battery powered. However, unless you're replacing existing mains versions, it's easier to install the battery model, as the batteries (and both versions of the alarm) are said to be good for 10 years. That's three years longer than the first-gen model.

Based on reviews posted on popular review sites as well as from First Alert's website, First Alert performs very well in terms of battery performance relative to other smart smoke detector brands.
The review site pcmag.com gives First Alert excellent ratings for battery performance in a review posted on its website. Specifically, this reviewer pointed out the following:
To test the alarm or silence it, use the Test/Silence button on the side of the device. This button can also be used to reset the alarm to its factory defaults. There's a quick connect power jack on the base of the alarm, along with a Discharge button that drains the internal battery. This is used when the alarm reaches its end of life after 10 years of use. The power jack is compatible with other First Alert alarms, but the Safe & Sound comes with two additional adapters that will fit most popular third-party power connectors. It also comes with a mounting plate and screws, an Alexa quick start guide, and a user manual.

For the First Alert Onelink AC10-500 to work properly, you must hardwire it into your home’s electrical grid, which serves as an uninterrupted power source. The device also comes with a 10-year sealed battery that functions as a backup if there’s a power outage. There's also battery-powered version, the DC10-500.
The online review website productreview.com.au, gave First Alert slightly below average ratings when it comes to battery performance versus other smoke & carbon monoxide detector brands. See the full review on productreview.com.au's site. From this review:
Bought 4 of these from Bunnings, advertised as having a battery life of 10 years. Literally only had them a few months and from the time we purchased them they have been nothing but trouble. First one unit started beeping randomly, got rid of it thinking it was a dud, and then another one did the same and then another. What a waste of money given these were expensive per unit compared to a standard smoke alarm. Wouldn't buy this brand again.

Based on ratings published by trusted online review sites as well as information from First Alert Onlink Safe and Sound's website, First Alert Onlink Safe and Sound performs average to better than average in terms of battery performance compared to other smart fire alarm manufacturers.
Based on a review posted on amazon.com, First Alert Onlink Safe and Sound was rated as fairly average for battery performance relative to competing smart smoke detector brands. Check out the entire review here. Specifically, this reviewer pointed out the following:
The company reduced the battery life on their next model below this one (which we also own) Their stated life expectancy got cut in HALF, basically because there's less battery inside. The older version of the next model use to be TEN years; now five. I think the problem is because, like ours, the battery died in less than 1 & ½ years.
