The Apple spec says battery life is up to 10 hours. There are too many variables of use to state an exact life. There's really no reason to run on full brightness, since it reduces battery life. The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter.
The iPad Air 4 offers all-day battery life, going 10 hours and 29 minutes on the Tom's Guide web-surfing-based battery test.
It lasted for 37 days in our standby test. It achieved a One Charge Rating of 10 hours and 43 minutes, which is decent for a phone with a 2650mAh battery and a 5-inch HD screen, but it could have been better.

Apple says the test involves browsing 25 popular websites using Wi-Fi, with screen brightness set to “8 clicks from bottom.” Under these conditions, the 16-inch MacBook Pro fails to beat even the M1 MacBook Air — it only gets 14 hours of life compared to the Air's 15 hours.
From my personal experience as well as a poll I ran on reddit, the average MacBook Air battery charge will last a few hours short of what's advertised from Apple (12 hours). Apple calims “all-day” battery, but the truth is it depends on what your using your Mac for.

The iPad Air may be smaller and much thinner than any full-sized iPad before it, but Apple still promises the same great battery life. That translates into up to 10 hours of web surfing or video watching on Wi-Fi, 9 hours on cellular (if you have a cellular model), and a whopping 24-hours as a personal hotspot.
The iPhone SE 3 and iPhone SE 2 include 2,018mAh and 1,821mAh batteries respectively. Apple claims that the 2022 iPhone can play 50 hours of audio on a single charge.
