Is this right?

Lately my battery has sucked. And I did a FDR with little to know improvement. After 8 hours I'm at 50% SO I got gsam battery monitor. This is what it shows.

What is your brightness set at? Also, 6 minutes of screen on time has you at 50% ? Maybe your battery is just going bad.

The screen is set to auto brightness and the power saver box is checked. I think jelly bean is the issue cause I was getting 15-20 hours before the update.

I think you will have to let Gsam run a bit longer to get any real useful info from it.
Battery use is very subjective and depends on so many variables. 50% in 8 hours might be very good depending on use.
Give it a few cycles with Gsam.

Ok I will let it run and see if there is anything wrong.

I agree with moset. Give gsam some time to make more accurate readings.

In regards to auto brightness and battery saver, that is the best way to go. However, consider the environment that you are in. If you are in a brightly lit room all the time and/or outside in the sun, then brightness is going to default to the higher levels and still use a lot of battery. As an alternative, you can change from auto brightness to around a 30% setting and leave the battery saver box checked. It will work great for overall indoor use but not outside in the sun.

Also, look in your widgets for the Motorola power control widget. It lets you cycle through the screen brightness settings without having to go into settings. I use it whenever I go outside to set my screen to max brightness and then back to auto when I go inside. Works great and saves lots of steps.

Finally, Consider other things running in the background that consume lots of battery such as facebook, any app that syncs or uploads photos, weather apps that constantly update and the gmail widget (not the app). All of those especially the gmail widget proved to be huge battery hogs on my phone.

You may also want to consider leaving wifi on all the time. For me it seems like my battery life is actually better when I leave wifi on.

I also leave my wifi on. As for widgets the only one I have on my home screen is the rings digital widget. Iv been using it ever since the circles theme came out. Not sure how long that's been. It does have a built in weather app and I set the auto update to every 120 minutes. I also put the power monitor widget in a home screen like you said to control the screen brightness and other things.

I'm not totally convinced yet but, the last couple of days I've turned off auto brightness. I have old eyes and auto worked well, however most of my use, I find 25% sufficient to easily read text.
I can see a reduction in the battery drain on a % per hour basis while i see little difference in the usability of the display.
If you tap the screen time listing on Gsam it will list the % of time at different brightness levels. Those numbers don't seem to have changed much, but my average screen battery use is down to around 8%/hr. from about 11#/hr.
The light sensor must use some battery. I'm leaning to that and whatever cpu time is used to manipulate the brightness is wasting some battery for my use.
I haven't figured out what the battery saver setting in brightness really does.

This is what gsam shows. Surely it's not using more battery on a dim setting.

You have to also look at the "time on" at the different levels. Your largest amount of screen on time (58%) was at the dim setting.
