Hi,
I’m facing the same issue, mostly around 40% case battery falls 1% after placing buds for some time.
I checked this following scenario based on what Nothing promised on the battery hrs for this buds as below(bolded). This is regardless of Case battery %
I just run a test run by charging the case at 100% and usually switched between ANC on/off and dual connection. Then, I watched movies in ott, music and youtube with the buds and waited for the case to drain 1%. I checked my phone screen time for these apps to calculate the actuals hrs of buds usage.
my average usage of buds per day is around 3.50 hrs for 6 days which is nearly 21 hrs and also have 100% batteries remaining in both buds which may add more or less additional 5hrs. so a total of 26 hrs, which is somewhat closer to the hrs said by Nothing (with ANC on and Dual connection on). but it is still weird this steep drain to 1% in the case after 40% .
I also tried charging the case upto 30% and used buds for 2hrs after some minutes case drained to 20% not 1%.
The charging cable i used was normal fast charging cable charging source is laptop. Case got fully charged as they say around 2hrs.
from these scenarios, I’m not sure the case is purposely draining the battery for some reason after reaching a hours of use which may be around 40-50%, not sure if it is due to software issue?. hope they will fix in firmware update.
Perhaps you can check the hours of usage if it matches the ones below:
Hours promised in Nothing website:
Earbuds plus charging case
35.5 hours of playback (ANC off)
24 hours of playback (ANC on)
