Sony SRS XB-21 Battery drain issue--Speaker not holding charge(low battery warning)check descriptio

Sorry for the low volume The issue that I was originally facing was that my Sony speaker(SRS XB-21) wasn&holding charge not even for a minute...As soon as I would disconnect it from the charger...it would blink for a second or two and then would go "Battery low please charge" and I had seen people with the same issue post videos on Youtube so when I finally did find a solution the inclination to post this online rose. TRUST me I really did try to RESET it about a freakin&GIZILLION times...but all that the Sony guide told me do had no effect even charging it for 12 hrs straight The part two of this is only to show that things are working great now...since originally I didn&intend to post it online ... WHAT I DID: Step 1- Open the speaker up totally...which obviously I didn&record cuz "I am noob"... but trust me it is easy only that you require a small phillips head screwdriver and if you really need help opening it up...here yo go Step 2- Next go ahead and disconnect the battery from the main logic board...or motherboard..(its a small white four contact pin)and you can easily notice wires running from it to a 18650 battery(blue) Step 3- Now connect the charger to the port as you see in the video and let it remain till it actually resets...try it once or twice and plug in the battery later... or plug in battery while it is already connected to the charger switched on(THIS is the MAIN STEP) Step 4- Reassemble...seriously I did this since its fun to open things up and see...
