Keep up the good work !!!

Great work Anker on an outstanding product

It's been working great although the battery usage showing on the screen is somewhat conservative.

I can however tell you how well this battery has worked for me and my Samsung Galaxy s4

It was working great until recently

Keep up the good work

Because it is working so like my old 2600 mah battery, I have cleared the dalvik cache and my user data, just to discard that my phone were thinking that my old 2600 mah battery were still in the phone
