Screen is destroying me. (Battery)

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.

Battery stats - weird awake times?

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.

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.

I tried clearing the cache from stock recovery but it did not help me

I wish I could say I have a solution but I have almost the same problem. With my opt, Google play services also is in on the battery drain. Would really like to have some tips. I've seen cases where one of these processes drains the battery, but not 2 or 3.

Very similar to my battery life. 2 hours screen on time, 12 hours off the charger, at 20%.

Do you have fingerprint scanner or tap to wake, and carry your phone in your pants pocket? If so, you may want to try having the screen facing away from you at all times to avoid accidental wakelocks.

Not OP, but personally I doubt it's that. I have charged my phone to 100%, then left it unplugged for 8 hours overnight for testing, and it will usually be at 80% the next morning. Most phones I have had won't drop below 90% overnight.

I just got my OP2 and it was at 93% when I started the initial setup process... after 44 minutes of setting up and downloading apps and the 2.1 update, it was at 52%. My Moto X Pure has "ok" battery life, but is much better in comparison... It only dropped about 20% during the initial setup, including ROOTing and doing a Nandroid.
So, I'm a little concerned about keeping the OP2 for this reason? Plus, the speaker sounds terrible.... But I've been using HTC dual front speaker phones for the past 2 1/2 years and most recently the Moto X Pure with dual front speakers. So the one speaker on the bottom is a bit of a let-down.

Guys, ok i charged my OP2 till 94% last night and left it. In the morning my battery was down to 54% and the major eatup of battery was done by MAPS. but my location was off and maps was not there in the running apps. SOT was 5 mins.
So, i am still trying to figure out as how to kill the Maps. But from morning (7 am) till now (3 pm), my batter was down only 23% and i have been constantly using my phone with SOT as 2 hrs.
Little weird but intersting.

Terrible Battery Life on Comparison to Others. Suggestions?.

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.

What's up with the battery life and "Cell standby" percentage?

I bought this 9T a few months ago. I think the SOT I had at first was about 10 hours, which is OK but I've seen better, but now after 3 months of usage it barely achieves 5 hours and the "Cell standby" rating—which I'm not sure what it stands for—is always at the top of the battery drainage list.
What's wrong with this phone? This makes no sense.

This is the cell/modem connexion 4G network.
You made use 2 times 20% of heavy data use in very short time (check it on the curve).
Check the same application you did with a wifi connexion because it can be your network 4G that is weak and lead to this heavy drain.

There are some draining problems in Miui lately. Something is causing this, that's the reason I skipped Xiaomi this time after years of using it.
"TechTablets" review of MiNote 10 also confirmed this. Basically you buy a phone with a beefy battery, but not getting the expected battery life.
I tried everything to sort this out, but it wasn't giving me any results. This was not the case with previous Xiaomi devices, like Mi8...

You said "lately". Yes but latest android 10 eu rom have a much better behavior.
Nlp wakelock is almost stopped and standby drain is lower than 0.5%/h (without AOD)
AOD at day consume some 1% additional.
MiNote10 was reported heavy consumer because of the camera needs.
they will improve at Xiaomi, not overnight but surely.
You'll come back to MIUI.
