    Hello,

    Replaced my three years old battery in my Samsung galaxy grand neo plus duos phone (GT-i9060i) that was little swollen, but otherwise worked well with no problems.

    Problems started with the original replacement. Phone died there times in a row at 30%, upon being connected to charger showed 0% and refused to boot up. Returned this one as faulty and got replacement.

    Sadly, the replacement did the same thing. Died at 20%, next time fast drop from 30% down to 4%, again died at 30 %. The voltage held well till 30 % but dropped to 3V right afterwards, taking the phone along. Upon charging, the curve skyrocketed straight up from 65% to 100% ( when charged from zero).

    Running stock 4.4.4 but rooted (wanna use my SDcard without that stupid malware protection).

    Was I too lucky to get two faulty batteries, or is my phone simply going haywire? anything I can do? Any tip will help me at this point...

    Thank you all.

    That's a dendrite (see Lithium Battery Dendrite links if you're interested in the subject). It's another form of defective battery. (Charging burns the dendrite off, returning the battery to its actual charge.)
