Hi, I am hoping someone can help. I have had the 5s for about 18 months. it has been great and working fine for running, cycling, pool and sea swimming. over the last few weeks the charging started to be a bit weird so did the rubbing alchohol clean and then replaced the cable for a new one. still running a bit weird but working. last week i went into the sea (it was pretty cold) and the unit died. got home cleaned it up and left it on the side for a bit then plugged it in and it started up and said it was 60% charged. as soon as i removed the charger it died. plugged it in again.. same thing. a few days on it now turns on and says 100% charged but again dies as soon as the cable is removed. tried various usb plugs and different computers but it seems like it might be a battery issue? HELP!!! i love this watch and want it up and running again.
