Soundcore P40i

Battery life and what the numbers mean

Soundcore claims 12 h per charge and 60 h with the case, and 10 minutes of charging gives 5 hours. Its own fine print drops the per-charge figure to about 10 h with ANC on, and independent testing at high volume with ANC landed around 9 h. A full case charge takes about 3 h over USB-C, about 1 h longer on a Qi pad. The case holds roughly four extra charges and props a phone horizontally, lid open, at a fixed angle.

Noise cancelling and sound

The P40i carries adaptive ANC with manual levels, multi-scene modes and wind reduction, but independent measurement puts its isolation at about -8.81 dB, with only about -1.25 dB in the bass. RTINGS calls the noise cancelling “nowhere near as effective” as Soundcore’s own Space A40 or Liberty 4 NC and says it barely touches low-frequency rumble. Mezha’s review found the ANC useful but imperfect: occasionally one earbud stops cancelling until you toggle it. Out of the box the Soundcore Signature tuning runs bass-heavy (about +8.9 dB) and bright (about +4.7 dB); the app EQ is what fixes it.

Fit, calls and the app

The stemmed design has no wings or stabilizers, and RTINGS reports a loose fit that needs periodic readjustment; five ear-tip sizes are in the box to compensate. Mezha found the fit comfortable over long sessions, so it is ear-dependent. Call quality is the other weak point: RTINGS rated the six-microphone system 5.6/10 and described voices as thin and distorted, though background-noise suppression is decent. The app is a strong point, with EQ presets, custom EQ, the HearID hearing test, a Safe Volume limiter and find-my-earbuds. Bluetooth 5.3 adds multipoint, but only SBC and AAC are supported, with no LDAC.

Repairs, upkeep and running costs

These are sealed true-wireless earbuds, so the battery is not user-replaceable and there are no user-serviceable parts. Ear tips have built-in grilles and five sizes are included; IPX5 handles sweat and splashes but not submersion. Soundcore advertises a hassle-free warranty, a 30-day money-back guarantee, lifetime support and a 30-day price match, though the exact warranty term was not fixed on the page read. There is no subscription; a Qi charger is optional and not included. One owner on Soundcore’s own review page reports the case getting quite hot after prolonged wireless charging, and the tested unit had a pungent chemical smell when opened.

Is it worth it?

At around $60 the P40i is easy to recommend for battery life, app depth and features. Soundcore lists it at $79.99, and Newegg has listed it at $59.99. As the price climbs toward the list figure the weak ANC and sub-par calls matter more, and if noise cancelling is the priority RTINGS points to the Space A40, Liberty 4 NC or Nothing Ear (a). Buy it for battery and features, not for strong noise cancelling or calls.

Which model this is

This page covers the Anker Soundcore P40i, model A3955, sold in Black, Oat White, Navy Blue and Purple. RTINGS tested the Black unit on firmware 01.61 and says the colors should perform similarly. Do not confuse it with the P20i/P25i, P31i, P30i, Space A40, Liberty 4 NC or P42i, which look similar but differ in ANC, case size or charging. Check the model number A3955 on the box or listing.
