Hi, I don't have much issue initially when I bought my Samsung Galaxy Buds+. However recently, the battery in my left ear bud will usually drain much faster than my right ear bud. In fact now, the battery in my left ear bud is 0% and already turned itself off but my right ear bud has 98% of battery left.
Thank you for reaching out. I would be happy to assist you further. Are you using the original charging cable that came with the Galaxy buds+?
Can I please have your full model number and the serial number on the bottom of your Galaxy buds charging case in a private message: http://bit.ly/2JH2rq2
No, I've been using my 5V charger and 5A charging cable from Huawei to charge the charging case.
On a side note, I already dropped you a private message, please check.
