Galaxy s4 update

[llhumphrey13]

I updated my Galaxy S4 2 days ago and yesterday it was fine but now the battery drains really fast and in charges insainly slow and sometimes the charge goes down instead of up. Is this happening to anyone else?

I know this is not what you want to hear, but doing a factory reset after an upgrade usually solves most issues, especially that one. Fortunately there are plenty of ways to back up your data, apps, etc.making the process less painful. Check other threads for precise instructions on how to do a factory reset the proper way and for info as to why this is such a popular course of action. I personally have done it several times and it has resolved some issues. Well worth the effort.
Good luck
