I'm not an incredibly advanced android user, I am smart and experienced enough to optimize some settings. I've got stock rom and andrew did. I do not have any application killer maps or anything stupid like that. I do you use elixir 2 widgets with all lots of widgets showing - like 32 of them. They are all set to refresh relatively frequently. However in not certain this is what is eating my battery as elixir has never been a problem on 4 other devices.
I also use very low brightness setting - 8% mostly and 23% or 65% very infrequently.
I'm seeing high 70%s of screen battery usage. Overall, I like the battery life but I'm concerned that if I do much more than I have been - which isn't much - or if I decide to get some gaming or put this screen up to real brightness, I'll have negligible life.
Summer question, what am I doing wrong, or what can I do including nonstock roms or further settings modifications to make sure I get the most of my battery life/screen use?
Obviously I'm about to remove elixir widgets and letting it run for a while to see if there's any change.

Uh, I'd say that 47% used with the device on for 9+ hours and 3+ hours of screen time is really good. There's nothing wrong with your Nexus and the high screen percentage is normal.

43% total.
But anyway to the point - really 77% screen usage is normal? I have seen lots of screens from other people where their screen usage is in the 45% range. I thought things wrong. Especially considering that I'm working at such a low brightness.

Seems normal to me, around 70% is pretty much what mine gets for Screen usage, unless I'm gaming a lot and then it drops to 40-50%.

Of all the battery you used, the screen used 77 percent of that. If you play a graphically intensive game, that percentage will decrease, but that doesn't mean it is using less battery, just less in comparison to other apps.
People who have screens using 45% are using MORE battery than you, other apps are balancing out that ratio. Basically, you want the screen to have the largest percentage, and there is nothing you can do to decrease screen drain other than turning brightness down as low as you can tolerate.
Having send thought about it for quite awhile, now I understand thanks for all the help.

Hey guys. I'm having a bit of a strange situation with my epic 4g. Basically, when I check my battery use %s, I'm getting in the upper 90s for display. Is my display really using someting lik 98% of my battery usage? Isn't the OLED screen for saving power?
Thanks!
SAMOLED is really power hungry when displaying white colors. Here's a picture leaked from LG. B is LG's, S is Samsung AMOLED (doesn't say if it's SAMOLED), and R is the iPhone 4's Retina Display.

Ok, so the display is using the most of the power, but the question is, what kind of battery life are you getting? If it is fairly decent, then dont worry about it too much. Just because the display is using the highest percentage of your battery, that just means everything else is using that much less of your battery. To really put it into context, you need to also supply the overall battery percentage left, time unplugged, and the screen on time. Otherwise, it is 98% of what? 10% of total battery used (9.8% used for the display)? 50% of total battery used (49% used for the display)? and that isnt even saying how much the screen was used...
If you're not getting acceptable battery life, then you can try a few things, like lowering your screen brightness, choose a darker wallpaper, or reducing your screen timeout setting (if you have it set to something other than the default 30 seconds)
Hmmm. I'd say its kinda decent, but it's still a bit lower than expected.
I have it set on minimum brightness and 30 second timeout, and my background is mostly black with no icons and a few grey widgets I'm my homescreen.
The usage % is pretty consistent even after most of my battery is empty.
What I find weird is tat my cell power usage is usually only a couple percent at most.
What is the deal with the awake times in 4.2.1? My phone shows that it is barely ever "awake" on the battery stats, despite 4 hours of screen usage today?
It's probably like me for the first couple of hours every morning then
I'm noticing the same thing. I would presume that the phone should be awake when the screen is on, but it show as sleeping. I think the awake stats are messed-up.
Sent from my Nexus 4 using xda premium
The battery seems to be the main annoyance with this phone. I have odd awake times too. I disabled everything in wireless, sync and Google now etc and still get odd readings. Its drains overnight more than any other Android phone I have used (S2 just flat lines overnight)
Then in use the battery can take a real dive. Youtube and Chrome are very battery hungry yet I get decent results from games like Asphalt?
I think they need to sort this out.
My Galaxy Nexus would easily go 24 hours on a charge. This phone won't make it 9 hours with light use.
I thought it would be as good or better than its twin, the LTE Optimus G. The fact that it only lasts half as long is insane.
I should clarify - I am not having problems with battery LIFE as opposed to screwy battery stats claiming my phone is rarely actually awake. This phone flatlines for me when idle as well as any other has - I rarely lose more then 1% an hour.
I never had this issue on my Galaxy Nexus, but I never bothered to update it beyond 4.1.2 since my Nexus 4 was en route. For example:

I've seen this in a ton of other screenshots as well and always thought it was peculiar behavior. Shouldn't the stats show "awake" when the screen is on? That's how all my previous phones have done it, and it's the way things make sense. With these stats, how are you supposed to tell when an app is waking the phone up as opposed to you waking the phone up by turning the screen on?
Unless that's what these new stats are representing? Maybe now instead of sowing ALL awake time, they only show awake time for when it isn't actually YOU waking up the phone, it's when something other than you wakes up the phone, like a rogue app. In which case this would be extremely handy.
Interesting theory, but it's a bit hard to prove. It's amazing no one has really discussed this yet.
Bump.
Mine looks the same... :S
im confused with the "keep awake" times of android OS and google services in battery stats. clearly eating battery while the phone is sleeping but i've tried turning off everything and still they show long keep awake times.

14 odd hours is pretty decent battery life? Even with the steep appearing drain. I can only average 10 hours and that's without touching my phone at all. if i moderately use it, it lasts 5 hours tops.
You're probably seeing a steep drain through sync apps, screen brightness, or a combination of a few other small things. If you're that worried about it, download better battery stats and monitor your phone for a few hours to check no apps have gone rogue.

These are my battery stats: Link
Obviously battery analysis is relative to the handset and user, but I honestly think your stats are above average.
Collect a battery stat of one full cycle and compare that, so the charging doesn't skew the results.
@ you dude: it could be yr wifi that causes yr battery to drain, by looking at yr stats.
anyways, get better battery stats like what ChrisRHolstein mentioned to look for the culprits.
and not forgetting, do a 2-3 battery discharge cycles.
WTF is going on with my battery? I have the S7 Flat snapdragon version (G930v) running the G930u software unrooted which removes all carrier bloat. Screen brightness is set to a little past half way. I have all setting provided by stock software optimized for maximum battery life other than running AOD. I am running a black Wallpaper/Lockscreen/ and an All black theme from the Theme Engine.. I Repeat, I have all stock firmware options Optimized for battery. Every single one. Wth hell is going on here. My battery time is looking Rediculous in comparison. Someone help me out here.

I feel asleep around 3am I guess with 89% and woke up just now close to 11. Heres battery over that 8hr period. 5% during that time. Standby drain is not bad it seems. But only 10hrs on 100% is crazy low compared to what some of you guys are getting.
End of Trial:
What can I do to get this increased.?
4.5 Hr of SOT is very Good. I am on the U firmware also and get 3 SOT. When you make comparisons, compare to SD Soc not the Samsung Exnos. You can download Gsam Battery and give it more permissions thru ADB and monitor. I noticed my proximity sensor (2) are giving high wakelocks.
The SD vs Exnos makes that much of a difference? I'm seeing people get 5.5-6.5screen on time in the main s7 thread. Granted not many relay the information as to weather they have SD/Exnoys or Flat/Edge.
4.5 hours when compared to 6 average over there, eh to me that's on the low end. I'd be losing my mind if I was only getting 3SoT.
I miss removable battery functionality.
Do you guys leave your screens on 24/7 or something? I use my phone quite a bit, but get 24 hours to a charge.
Is this ok?
At this brightness level plus I have turned off buttons backlight.

I get around 4 hours sot when I get home, here is my day with my phone.
730am start streaming audio books through Bluetooth facebook sms email.
4pm stop streaming books 75% battery.
5pm games facebook email sms.
10pm bed time, end the day with 330 to 4 hours sot and 15%battery remaining.
Can someone explain to me, please, what is going on with my S8. The drain is crazy.

Is that not normal? lol Mine pretty much looks the same. All my apps are at the bottom of the list but iam getting great battery life
what is your SOT?
i get same system usage as you but i 5-6 sot
4-6 SOT, actually, I thought Android battery life has evolved when I bought galaxy s8. But no, it keeps sucking my battery life even when it's in my pocket.
Unfortunately this issue is present on all samsung galaxy phones i've owned recently (s6 edge, s7).
I can't understand why the battery life is so bad and inconsistent.
No matter if all day wifi or mixed (data 4g/lte & wifi)
The background usage is pretty minimal. I don't understand why people complain that "something" however small is going on with the phone when the screen is off. The system is still alive, after all. Notifications need to get through, sensors need to be active to wake the phone (fingerprint, accelerometer, etc), apps need to be kept in memory, not to mention the always on display. Is it that surprising that if battery went down 10 percent during sleep 20, 30 or even 80 of that drop is due to these things? (that's what that reading indicates after all, 9% is not from total battery capacity, but 9% out of the amount drained).
Sorry for the rude rant, but people "expect" too much of the standby times.
Can the battery be improved? Certainly. Can the power drain be improved? Of course. But never to the point where it consumes absolutely nothing at all during sleep. Except if you turn the phone off.

20 hours on battery, 30%left. OP must be trolling.
Normal
I noticed finger print loves to break deep sleep.
4-6 hours of SOT? That's pretty good though... Same with what most people are getting including me. If I drained it all the way down I could probably reach 7 hours SOT. Totally beats the 3 hours SOT I got with my Note 5.

Did your previous phone with a 3000mah battery and a bigass screen get 4-6 hours of sot? I thought so...

Did you realize that when you total up the battery usage, you won't get 100% of battery charge?
