Fairly new user. I like to listen 10-6, full shift.
Nope.
One earbud (rt). Lasts till ~ 1500. Swap to lft.
This one dies after 2 hours… or at least disconnects.
Fairphone ‘shop’ shows no stock.
My usual battery supplier hasn’t got any?
I assume you are talking of a pair of Fairbuds here (Fairphone used to sell “TWS earbuds” before, but as you say you’re a new user, it seems somewhat certain yours are Fairbuds).
Concerning the earbud batteries, their shop entry indeed creates a wrong first impression of unavailability. I just tried it myself and you need to pick your colour first before the “Coming soon” label disappears.
If I understand this correctly, you are listening from 10:00 to 18:00, which would make it 8 hours? Instead, the battery only lasts up to 15:00 which is 5 hours?
If that is correct, then there is no problem with the battery. This is roughly within the stated capacity of the product. From the shop site:
Up to 6 hours of listening in a single charge and 20 additional hours with charging case.
To my understanding 6 hours is the best case with neither ANC nor ambient mode active. Both reduce runtime. I never listened for 6 hours straight, but 4 were certainly not an issue. I did not check battery level after that, so no idea how much longer they should have lasted.
That the second one only lasts 2 hours is strange, though. Are you keeping it in the case while not in use? Is the case battery charged?
I agree with @urs_lesse. Before ordering any parts yourself, please contact support and state your problem to them.
