I bought the Boat Rockerz 255 Pro Plus bluetooth earphones about a month ago. I don't use them much and I need to charge them only about once a week.
A few days ago, I noticed that the earphones battery was discharging too quickly. One day, at night, when I switched off the earphones, the battery was at 50%, the next day, when I tried turning it on, it wouldn't start and I had to connect the charger for two or three minutes after which the battery reached 10%.
Earlier, I used to charge the earphones with the small charging cable provided by Boat. Before the present problem started, I had charged the earphones using a Samsung cable.
Thinking there's a problem with the battery, I made a warranty request on the Boat site. Then I charged the earphones using the cable provided by Boat, and yesterday night, when I switched it off, it was at 100% battery, and this morning, when I turned it on, it was at 90%, and I've been using it for more than an hour now and the battery is still at 90%.
Can a charging cable cause such a problem? I use the Samsung cable regularly and it works. Boat itself, on its site, only recommends, but does not insist, on using the cable provided by them.
