Question about Apple btooth headset

[Y-not]

i have recently bought an iphone headset thru ebay. Everything seems ok. When i pair the phone with the headset it works ok. When connected with the phone the phone shows the btooth sign and a number next to it (like 870 or 0) is this number the charge left on the headset? If it is, then when i see zero as the value of charge so soon after fully charging, i am worried that the headsets bAttery is broken.

I have a very limited to test it fully so i would appriciate any idea about how the headset works and if seeing zero so soon after full charge means something bad

Thanks

The only thing I have seen as a number next to my BT symbol is numeric battery enabled in boss prefs. Never any numbers otherwise. Where are you seeing the numbers? In the general settings panel?

could the numbers be the name (model number) of the bt ?

Not if they change to 0. Also electronics codes include a prefix or suffix of numbers such as the HT300 headset
