Galaxy s 3 charging issue

[AC Question]

I have the galaxy s3 and it wont charge 100% it actually is losing battery life while charging and it will charge on a different cable but not on my own cable it came with but it doesn't stay charged 100% for more than 5-10 minutes. How can i fix it??

How long can the battery be used?Maybe you should charge it for longer.

Sounds as if the battery is at end of life. Replace it. (If the phone is using more current than it can draw from the charger, there's nothing left to charge the battery, the battery is actually being used to power the phone. It's just discharging slower. But 5-10 minutes until it's discharged? It's shot.)

Read our guide, The Care and Feeding of Lithium Polymer Batteries, so you don't kill the replacement too.
