Why does my phone only work when its charging
it starts up and then goes off repeatedly.
Is this a good question?
If your phone only works when connected to the charger, most probably the battery is failing to hold its' charge and will need to be replaced. Even rechargeable batteries have a life span.
Here is the Ifixit guide on how to replace the battery.
Here is a link to just one supplier of the battery. If this supplier doesn't suit you there are others, just go online and search for Samsung Galaxy S5 Active battery.
