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.

Running siyah kernel with cricklerom
Fantastic
show me your screen on time pls. i can do that with stock battery too with low use. 37% doesnt look like you touched your phone much..
that's pretty bad. I can go as long as 3 days with stock battery
That is indeed easily done with a stock battery and stock Samsung or CM7 rom and with moderate use.
Would help if you actually used your phone, anyone can get double that on standby on a normal battery
Besides, shouldn't this topic been placed in the Accessories sub-forums?
blimey and i thought that was good. Onoly get aboout 24hrs with the stock battery....ok i'll crawl back into my hole....

You don't have to do that but people here are much more interested in how much life you get with heavy (screen on) usage, me included. How much was it, if you dont mind me asking?
im not a heavey user, but with medium useage, 15+ downloads, surfing the net on and off through out the day, emails through out the day, f/b updating and numerous texting and a few calls.....i suppose for my normal use on stock battery i got just over 24hrs use so the extra 300Mah is more than welcome. Plus i can slip the original stock battery in my pocket when i go out just incase i need extra umph. Oh well im happy with it...please move to accessories if i have posted in wrong forum..infact MODS if you want to delete this thread then please be my guest....
OK... realistically though, screen on time is the real indicator, along with usage patterns (were you web browsing, gaming? what games? how bright was the screen etc). Screen on time can be found out by Settings > About Phone > Battery Usage > Display = Time on (just in case you weren't aware).
How much did the battery cost?
Oh... and what theme are you using (I'm liking those icons at the top).
besides the screen on time you should also consider the data volume transfered via radio, that kills my battery even faster than the screen although i'm living in a big city with solid coverage...
There is already a big thread on the OEM 2000mah battery.

Hahaha, your signature made me laugh, thx
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.

Since I see so much Ignorant in the Battery thread, I like to point out (rant) some things..
1. A person 6 hour of Screen On Time usage is different from person to person.
2. Temperature can have a great affect on battery life.
3. Signal strength can have a great affect on battery life.
So with that in mind, I suggest everyone try to do a PC Mark bench, it is fair and give people a much better idea of what of what they should be getting. To do this test here are the few settings you need to set
1. BRIGHTNESS AT 23-25% (EYEBALL IT)
2. Wifi on
3. do not disable Mobile data or sync
4. Clear all RAM before start
below are the CONTROL numbers from a stock rom (pictures are from greenbot.com)

Below is my stat, using arter kernel and foreverloco rom. (I DO UNDERVOLT MY KERNEL) ambient is about 20C
I get what I get based on MY real world usage. I don't need synthetic benchmarks or software to tell me anything. Why do people obsess about this so much?

To see if your phone performing at optimum settings. The problem is there is no set controls or way to bench it properly and this is the way how.
Why this benchmark is useless? Let's say we have two Edge+, under this benchmark CPU on both runs at 1GHz all the time and both last for 8h. Now imagine that one device runs program/service that keeps waking up the device every few minutes and the other goes and stays into deep sleep without any problems. Benchmark might show no difference or just slight difference. In real life 1 device will get 6h sot during 48 h usage, the other one will get 3h sot and run out of juice in less than 24h.
Good benchmark should simulate at least 24h usage with breaks to test standby drain as well.

Battery Life Discussion
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.
My S7 Edge Battery life is very strange , I use power saving mode (Mid) with Res set on FHD, and I can say, I maybe last 8 hours or so ? Maybe 4 hours screen on time. If I use the normal mode, the battery drains like hell. Yet, when I use max power saving , I can go hours without 1% dropping off my battery. Is this how the S7 Edges are or is my battery at fault somehow?
Note this was before Oreo and still is the same after.

My battery lasts 17 hours with 4 to 5 hours sot,depends as some days I hardly use my phone as much as other days
You can check your battery cycles and battery health percentage via the app "Phone info - Samsung" in the play store.
I ended up replacing the battery for that extra 5-10%+ from a new battery. Phone lasts a day or two depending on how much I use it, I'm not a heavy user but I do have Wi-Fi, 4G, go on reddit / browse etc). I charge every morning and night so pretty much only get to as low as 60% every day.
Is this original or fake guys
