Battery Power unstable? is it 80% or 100%?

I love my head set.... it was a gift and I fully intend to use it every day. 

Straight out of the box it was charged to 40%.  I used it at work yesterday... got most of the day on that 40%.... and brought it home to charge it.  

I plugged it in... let it sit for 2 hours.... came back to find 5 lights on (indicating fully charged)  So I unplugged it and turned it on to hear the voice say the charge percentage

She said "Battery charged 80%" so I plugged it back in and left it for another hour.  I came back... still 5 lights on (nothing flashing either) and I turned it on and heard again "Battery charged 80%"   I checked all the connections and I wasnt 100% sure that it was all connected correctly so I moved it to a different outlet... plugged it all in ... and left it for 30 more minutes....  and still the voice said "80%" .   I figured I had a bad battery and I would take it back after work on Thursday (today).    So I bring it into my office (so it doesnt get stolen) and figure... Ill just use it during the day and take it back tonight.   

I turn it on to connect it with my phone.... and the voice says  "Battery Charged 100%"


My question... is my battery faulty?  should i swap it out?

It looks like there is a firm ware update... but given all the issues everyone has had with it.... I dont know if I want to go that route.

Hi nettsiebaby,


Thanks for the post, and welcome to the community!


It sounds like the charge was just between the 80% and 100% report.  Can you try charging it overnight?  Depending on the headset you just received, it may take more than two hours for a full charge.

OK... so I charged it over night... and when i turned it back on this morning it said "Battery 100%"  sounds good right?

Well ... that was 5:30am.  I have been listening to music all day.  I just tested the battery? it still says 100% and shows 5 lights

My headset has been either playing music, movies or phone calls non stop from 8am until 1:30pm.... and it still says 100%

after almost 6 hours of continuos play i would expect it to provide a report of less than 100%

which makes me wonder if I have a damaged battery in some way.
