In 32 minutes, your screen has been on 30 minutes of that time, hence the high percentage... Nothing looks odd about that. If you think it is killing your battery, you should probably look elsewhere like not going to deep sleep, or constant syncing. Need to see better battery stats or cpu spy... If that is the concern.

Well, from your pics, it seems that your screen was on for 30 of the 32 minutes that your phone was on battery. Takes a lot of power to light up a display. Most folks can get by with a days worth of battery with 3-5 hours of screen on time. Some do better, some do worse.

I just don't think you realise how much of a battery eater our screens are... that is perfectly normal and the way it should be....

There is nothing wrong with your phone or battery. It seems like your screen has been on around 2 hours. 50% battery loss is about avg. with 2 hours screen time.
There is also about 100 other battery threads. You should have posted there.
Yeah I know sorry. I'm just at work and didn't have time to search it

5 hour display time!? sick battery life
Lol um yea I usually last about 13 hours total outer charge with moderate/heavy use and using juice defender to disable data while screens not in use..
Sent from my SGH-T989 using XDA App
No about 2 hour display time.
Sent from my SGH-T989 using XDA App
I thought juice defender drained the battery?
Sent from my SGH-T989 using XDA App
Well you thought wrong lol it gives an extra couple hours with use and it'll last about 4 days if I barely use out
Sent from my SGH-T989 using XDA App
so you get 2 hours display time at 50%...
so you get about 4 hours display time total?
Well all i can say is...
WELCOME~! you have average battery life for the t989! other devices barely break 3 hours! congrats!
2 hours of display time (also depending on how bright you have had it) with 50% left is pretty good.
I'd have to disagree that 2 hours is good, I'd call it subprime. Do some searching on XDA. There are plenty of wonderful tutorials and guides to small things you can do to help it out quite a bit.

i need help reading battery graph

So i would like to learn how to read my battery graph also this is the rom im running atm...
Also my question is how do i fix this?
Sent from my SPH-D710 using xda premium
fix what?
It looks like your battery took a steep dive. The graph shows at what rate your battery discharges. Since youre on ics, battery life isnt going to be phenomenal. What are you trying to fix?

Confused

Does this mean my display has used 84% of my battery. Its been off the whole night.
Sent from my PC36100 using xda premium
No, your battery is still at 97% so out of the 3% consumed, 84% of that 3% was used by the screen. Those percentages represent which apps have used the amount of battery used since off charger. Savvy?

I thought of putting this topic up because i saw how crazy the battery Life is. I put it charge at the time when i was not thinking to put the topic up(for about 2 minutes when the battery was at 32% or so). And thats why it says discharging!

8 hours of on screen time is not reasonable. The percentage is not of the battery time, it's how much battery was used by the display.
He needs to show his on screen time by actually clicking on Screen Display.

Correct, his estimation was simply outrageous. There are many factors that determine how much battery the display consumes. The biggest is the brightness at which the display was at the entire time, 0% brightness obviously last much longer than 100% brightness. Also the types of colors being displayed, dark colors on a OLED display drain less battery than bright colors.

I find ways to have better battery life. Obviously if you have brightness at 100% it will kill battery unless you have a better battery regardless

Again....display on time? People always want to show off the best battery reports but never know how. That screenshot means very little, my guess is your phone was deep sleeping 3/4 that time.
