How do I make my battery last longer?

Kernel, Android System and Media server battery drain.

Hi,
the GSAM app on my HTC ONE M8 says that my app usage is higher than my screen and three of the main battery drainers are: Kernel (Android OS), Android System and System (Mediaserver).

I use my phone properly, charge it very well and have had 4 android phones. None were like this.
I have the latest firmware for the M8 (4.4.4).
My screen on time is not that good now, around 2-3 hours but when I first got the phone (3 months ago) it was 4-5 hours.

How do I reduce those 3 apps to make it last longer?

I have quite a lot of views but no answer? Does anyone know?

Re: Kernel, Android System and Media server battery drain.

I wish I could help you, but I am kind of in the same boat. Installed GSAM a while ago on my S3 as I was having some wicked battery draining issues...read as having to charge my phone several times a day all of a sudden despite not changing my phone use habits.

Here are my 3 main battery drainers
Android System 22.4%
Google Search 16.1%
Kernel 8.4%

The google search puzzles me. Not sure how to stop that from running in the background.

If anyone has any tips, they would be greatly appreciated
