Hello everyone,
Currently i have a 3 week old chord mojo with me, and i am noticing that currently the battery life last less than 8 hours after a full charge
I usually charge the mojo overnight when i sleep, and i never use the mojo while charging the battery simultaneously.
Post #3 mentioned that it should be fine but is there anyone experiencing the same thing as i do? Also i notice some sort of a buzzing sound when i charge the mojo.
Does this warrant me to file a claim to the seller?
My mojo is number 42xxx and i charge it using a sony z5 phone charger if it matters
Hello,
I think that the battery life will be partly dependant on the impedance of the headphones, and how loud you listen.
Regarding the charging noise, there are a few posts about this subject, in the battery and charging section of post #3. I have copied a selection:
I use a samsung phone charger without any problems, and apple chargers and anker chargers are popular (because they work well) with posters on this thread.
Usually a change of charger cures the noise problems, but occasionally a change of cable is needed.
So I suggest trying an alternative charger as a first step.

Also, some USB cables have high resistance, and this makes the problem worse - so using a different cable can make the mechanical noise go away. The PSU itself can make it better or worse. Don't worry about it if you hear the noise, Mojo is not faulty and will continue to be reliable.

Case 1: Virtually silent, only heard very minor hiss when ear is pretty much on the unit
Case 2: Only noticeable hiss when you put your ears near the unit
Case 3: Loud whine lasting the only the first few seconds, faint charging noise after that.
Case 4: Loud whine, and it goes on for a few seconds and off for a few (voltage drop causing charging circuit to shut down)
Combo 1: Sony or Samsung charger + Sony or Samsung USB cable + extension cord = Case 4
Combo 2: Sony or Samsung charger + Any cable = Case 3
Combo 3: Apple 1A charger + Sony or Samsung USB cable = Case 2
Combo 4: Anker charger + Sony or Samsung USB cable = Case 2, slightly quieter than combo 3
Combo 5: Sony or Samsung charger + long 6ft Anker cable (same cable length as Combo 1) = Case 3
Combo 6: Apple 1A charger + Anker cable/Chord Mojo's bundled cable = Case 1
Combo 7: Anker charger + Anker cable/Chord Mojo's bundled cable = Case 1, slightly quieter than combo 6 directly compared, with no pattern to the noise (always the same loudness)
