[Q] Is this normal battery drain?

Ok guys, I keep hearing people ranting and raving about this phone's battery, however I feel that mine is either faulty or everyone else is exaggerating. On a typical day, of normal usage, heavy web browsing, occasional 10 minute game session, I can get about 4 hours screen on time, and about 14 hours total time before it's dead and I need to charge. I have minimal wake-locks now that I've figured the majority of them out, and keep location services on device sensor only. My device is deep sleeping more than being awake, and will last quite a while while asleep, battery doesn't seem to abnormally drain while asleep. Every time I've been able to track it down to a wake-lock issue if it has.
It's draining very fast (it seems) while screen is on though. Wifi calling is almost always on the majority of the time.
Any ideas? Is this way off? Or is this the norm?
I've done the usual factory restores and all that, and still no improvement.
Thanks!
Example:

Are you using a custom kernel? You could try dorimanx's and heavily skew the CPU towards a lighter load
I used to get 4h on screen time for quite a while, but k realised that it was cos of 4G @ and the way I used my phone. If you read a lot and hardly launch or close anything the battery life gets better very quickly

That seems about right.
On stock I get between 4 and 6 hours screen time and about 24 hours on battery. Being on WiFi rather than 3g helps a lot and turning down the screen brightness.

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.

Battery drain

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?

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.
