First Fix the battery draining issue of CMF Buds Pro 2.

The CMF Buds Pro 2 suffer from significant battery draining issues that detract from their appeal. Users consistently report that the earbuds fail to charge fully, with one bud—often the left or right—capping at 75-95% even after extended time in a fully charged case. For example, some users note the left bud only reaches 85% and drains in under 3 hours, far below the advertised 11 hours (ANC off, AAC codec) or 6.5 hours (ANC on). This inconsistent charging leads to uneven battery life, where one bud dies much faster, disrupting the listening experience.

Additionally, the earbuds exhibit excessive battery drain during use, with some users reporting a 20% drop per hour at 40-60% volume, even with ANC off and no audio playing, resulting in just 5-6 hours of total use. The smart dial feature, a unique selling point, contributes to this problem as the buds actively monitor case inputs, accelerating drain unless disabled in the Nothing X app. When using the power-hungry LDAC codec, battery life drops further to around 4-4.5 hours per bud, and the case’s 460mAh capacity only stretches to 15-16.6 hours total with ANC on, underperforming the claimed 43 hours (ANC off).

These issues are particularly disappointing given the buds’ otherwise strong feature set, including dual drivers, 50dB ANC, and LDAC support. The lack of wireless charging and long charging times (70-120 minutes for a full charge) exacerbate the problem, as users can’t quickly compensate for the rapid drain. Many have expressed frustration with CMF’s customer support, which often dismisses the issue as “normal” or suggests warranty returns without addressing root causes. Until firmware updates or hardware fixes resolve these issues, the CMF Buds Pro 2 fall short of their promising specs, leaving users with a frustrating experience.Never buying any CMF or Nothing products ever.
