Why is my battery life on my S4 draining so fast?

[AC Question]

I charge my phone and is 100% charged only to be down to 20%(or less) in less than 2 hours....Atimes without making calls!What do I do?
Is it because of SME regular updates "somewhere" or what is exactly causing the battery to drain so fast even after switching on the "power saving" indicator.

I need help!

Welcome to Android Central! Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).

Hi all, thought I would ask here rather than start a new similar thread, posting on behalf of a friend.

S4 100% charge lasts a couple of hours even when in pocket and not being used. Attached is a screenshot of the useage.

Hopefully someone can help.
