Why is my Samsung S2 charging slowly suddenly

[AC Question]

After a recent update, my Samsung Tab S2 started taking a long time to charge.......as little as 15% an hour. It seems to discharge quickly......25-30% in an hour of use. Using OS6.0.1

Is there a way to turn fast charge on?

Welcome to Android Central! Have you tried a different cable and/or charging plug?

I'd suspect the battery first. Even if it's been well-treated, it's 5 years old.

The OP's talking about the Tab S2, not the Galaxy S II. The Tab S2 is about a year old.
