Hi all,
I recently bought a pair of H9i and really got amazed from the sound and build quality.
However, I noticed that while using them over Bluetooth they are draining my iPhone X's battery pretty quickly (about 20% in 1 and a half hour of music).
While my phone is connected to the cars multimedia system with bluetooth I don't see any extra-ordinary battery drainage.
Anyone experiences the same issue or has some tips?
