so i have a samsung galaxy s3 and have been using it for 2 months now and just recently, it started to take me 8 hours to fully charge my phone. it wasnt like this at first. So , i thought there was something wrong with my battery but after a while, i realised the problem was my charger. anyways, now im using an old mobile phone charger and it charges my phone like normal but im just worried if this is okay or will it spoil my phone or its battery life? cause i read the manual and it said to only use a charger that is specified for the phone type or else the device or battery might get damaged. is this true?
here's some info about the charger if it helps.
s3 charger : output 5.0v - 1.0A
the mobile phone charger im using now : output 4.75v - 0.55A
