How AirPods and their case charge: how fast, what gets prioritized (and when), more

One user analyzed how the novel AirPods in addition to their representative genuinely charge, revealing a bunch of interesting details nigh accuse times, trickle charging, boost charging in addition to hence forth.

For the purposes of this test, every bit commencement noted past times The Loop’s Dave Mark, Reddit user “colinstalter” was charging his second-generation AirPods in addition to the regular charging case, non the Qi wireless counterpart, amongst a measure 5-watt brick in addition to a measure cable. He in addition to then recorded the battery percentages at diverse times using the Battery widget on iPhone.

Here are his key takeaways:

• The AirPods “boost” accuse for the commencement 3.5 minutes at 2.35 watts (0.46A / 5.1V)


• The earbuds accept xxx minutes to completely accuse from dead


• The charging representative + dead AirPods accept 2 hours to fully charge


• The charging representative waits to accuse until the earbuds striking twenty percent


• AirPods + the charging representative never pull to a greater extent than than 2.5 watts total

The charging representative in all probability waits to accuse itself until AirPods striking twenty percent because it needs to communicate amongst the earbuds (if y'all conduct keep AirPods, y'all may conduct keep noticed that audio lineament in addition to connectedness reliability tends to accept a striking when they drib to twenty percent, peculiarly when y'all take away heed the 2nd audible alert marker 10 percent charge).

“The logic simply prioritizes juicing upward the AirPods first,” the poster commented. “I’m assuming in that place is a thermal limit, but I was surprised it doesn’t at to the lowest degree pull five watts in addition to accuse both.”

Another interesting observation: the representative draws extra mightiness from the charger for nigh 3-4 minutes every fourth dimension y'all opened upward the lid. One possible explanation is that the representative is inward depression mightiness means when closed, but ramps upward when opened.

The AirPods representative battery

And when your AirPods striking twenty percent, the representative in addition to then trickle-charges until the buds striking xc percent. If you’re juicing upward simply the charging representative amongst no earbuds inward it, it volition “boost” accuse for the commencement 10 minutes earlier settling at roughly 1.43 watts.

A teardown analyst of the novel AirPods revealed that the representative holds 1,520 mWh piece each earbud holds 93 mWh, for a total of 1.706 mWh. You tin flame job a to a greater extent than powerful charger but that won’t attention y'all much because AirPods in addition to their representative volition never pull to a greater extent than mightiness than needed.
