Battery issues

[CallMeBlurr]

I have the Samsung Galaxy S4 and recently the battery life has been shocking (no pun intended!).

As of yesterday (Monday 3rd August 2015) I have a new battery; in the hopes it could help. I've found the results to be mixed.

Before the new battery my power graph was a sharp decline. Percentage could be at 10% by 8pm. With the new battery I'm 10% or so higher.

The statistics I'm supplying are with normal use. Though sometimes I'll use Spotify, YouTube or the game Hearthstone.

Bear with me as I try to upload photos.

Also if you need any info I've missed, then call me out on that please.

You can see in the first image, that sharp decline was my battery life for a few months. The graph highlighted is the best it's been in months but I'm still concerned.

Does anyone have any advice?

Use DU Batery Saver. Some hidden app should be drain your battery down. And DU Batery saver control your phone even it's sleep And automatically shut down this hidden app. And there is so called "White list" too of course, where you can put apps which can't be shut down for ever.
