My ‘Samsung Galaxy Tab 4’ is loses charge too quickly and when it’s left charging for hours, it only comes out with 20 percent. Even after 8 hours of continuous charging it will only have 40%. The problem started around 6 months after it was bought and it’s still fairly new at 1.5 years. I suspect a battery issue or a faulty charger. What do you think is wrong and is it worth fixing. I appreciate if you could reply. S. RM
I’d get a new battery. Maybe the battery has failed and start trouble shooting with a known-good battery.
