Battery drain & WQHD+

I've heard that the display doesn't come set to wqhd+ out of the box. Do you think setting it to this will cause a huge battery drain?

If the S7 and S7 edge are any indication, it should knock about 30 minutes off of its usual 14-15 hour estimates.
The main reason, IMO, not to use QHD+ is that it's pretty much useless for every day usage unless you're using VR. And if you're using VR, your battery's pretty screwed anyway, lol.

Don't you wish thy we could hear from Samsung about this directly. Argh

I hear the new display are more efficient than the S7 displays according to DisplayMate. FHD and QHD+ doesn't have a big difference on drain either.

That's true, also a more efficient SoC and new battery tech that should hold charge better over time. It should balance things out. Software optimisation also helps.

this has already been discussed in another thread.
independent results put the SOT battery life at 42 minites MORE than an S7E, and i believe the tests were run at QHD

S8 Plus battery drain
Hello,
I am using S8 plus (Exynos) with dual sim.
SIM 1 -GSM only- totally for voice calls
SIM 2 - LTE only - totally for data and rarely for calls
QHD+
Location Off
AOD ON
Bluetooth, NFC , smart sensors etc- OFF
No apps run in the background.
I do not use power saving mode.
Moderate user - Mostly texting, Facebook, Online games, Youtube, sometimes reading.
The stats show around 24 hrs remaining after a full charge.
The SOT experienced is around 3 hrs- 3.5 hrs which I think is less, considering that I am not a heavy user.
What I want to understand is, why are some users reporting ridiculous SOT (7-8 hrs) even with heavy usage?
Am I interpreting these stats incorrectly? Is my battery not good?
I have tried to clear cache partition, even formatted my phone sometime back, but still, it hurts to see a lower SOT and battery draining rapidly.
I don't intend to troll, just clearing my doubts.
Kindly suggest.
Thanks
Sahil

You should probably start a new post since this thread has been inactive for a few months and is specifically about battery drain and resolution settings.
On a side note I'm in the same range you are, my cell reception sucks at work so I'm assuming that's part of my battery drain too.

Post your Battery life!!! S8 only

Please post your battery life.
Mention model and carrier.
This thread is for S8 only. S8+ users use this one https://forum.xda-developers.com/galaxy-s8+/how-to/post-battery-life-t3587865

I'm not using the aod.

No screen shots right now, but about 5 hours of SoT with moderate use, and up to 7 hours of lightweight usage.

1st day FHD+
Second day WQHD+

please do mention SOT.

I didnt have AOD on during this day of use. T Mobile S8. Also, resolution set to FHD.

I do really like the SOT but the op3 was a lot quicker with charging than the s8 with standard adapter :/

Battery on my s8 exynos is just as good as the s7 edge was last year at launch. At least 12h stby with 7hrs SOT on FHD setting with some 4g and very light gaming. This is my 4th charge.
I would say this is great for only 3000mah.

Someone post with cellular only plz

T-mobile S8
AOD on during the day but decided to turn it off overnight to see my overnight standby.
Moderate use
Maybe an hour or two in poor reception and actually i streamed instagram live in the poor reception area for like 10 minutes or so too.
Light to moderate snapchat videos
Only thing to note is that the last 40 min of SOT was min brightness viewing these forums before bed.
This is pretty good considering the usage though!
I wonder how well it can be if I disable Facebook and snapchat

Hoooly cow
Only LTE, no WiFi, all sync

Ok. So it looks like my battery is getting better and better

Extremely pleased

I'm happy, big step up from my N6.

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Honor 9 before depleting the battery.
Then, drop a comment if you have anything to add!

great device, get 5hrs of SOT under moderate usage

Wow, 8.5h sot is a lot! Maybe I need to check the battery guide out. On the other hand I was playing with the Honor 9 all day because I have it the second day and got 7 hours sot with 5% left. More than enough for me normally!

So, how does it compare to honor 8, is the additional 200mAh makes any noticeable difference?!

That's all I need to know

I think the battery life of the Honor 9 is ok but could be better. I am used to Samsung devices with OLED display technology where you get better SOTs. In my case with my Honor 9 I get around 7 hrs SOT and 1.5 days of usage without charging (with some battery tweaks and screen brighness to 50%). In comparision with my old Galaxy A3 I could reach easily 2 days which was perfect.
If the Honor 9 would have OLED display it would be amazing. Maybe the next Honor will get one, then I definately would buy again.

Sounds interesting. I don't have any experience with Greenify but 10 % drop sounds less than normal. Which screen brightness do you use? In chrome do you also use it in data save mode?

Rommco05 said:
Yes I will reported when 50% of battery gone. Brightness is on 25-30% and no data saver in Chrome. You use data saver? Is it discutable if this can help improve battery, better to say not much tested data savers. I think android must work more if want to save some data...
Click to expand...

Yes I use data saver in Chrome. I think it does a good job and it even tells you how much data it saves (in percent). For me it is around 15-25% less data for different websites. Less data exchange means also less battery drop and faster site loading. I would recommend it.

My honor 9 only gets about max. 4 hours of screen time with battery saving on and it doesn't last me a day with average use. I play one game but it's not a heavy one (clash of clans) but only for about max. 30min/day. My battery even drains faster than my galaxy j5 2015 (who is 2 years old) which is dissapointing. I lose about 5-8% battery for Facebooking for 10minutes.
Is there something wrong with my device or is it just my usage?

I go my phone on thursday the 8th and I'm currently I'm getting about 3-4h of SOT.
I would say I'm a pretty heavy user, a lot of Podcasts, Spotify and Youtube (I've installed the Vanced version of Youtube).
I'm also not running the phone on 2k but 1080p settings. I have yet to enable batterysaving mode but I might try having it on medium where it limits CPU power to 70% and decreases background tasks.
Over night when its not plugged in i'm loosing about 1.4% per hour, during the day when I'm using it about 10-11% per hour.
Not really that impressed by it to be honest.
Although I'm coming from a Mi MAX that was designed for batterylife and that I modded to be as efficent as possible.
The phone is not rooted but I've just installed SABS, BK Disabler so I'll be disabling some bloat (I don't use SHealth, GearVR etc) and I'll see if it Improves when the phone stablizes over the coming days.

I'm getting about 3-4h of SOT with an unrooted Galaxy S9+. No power saving modes enabled and a lot of use such as Podcasts, Youtube, Spotify and such.

I am a heavy user. Today is my first full day with the phone. I restored the apps from Samsung cloud, and the messages from other phone using dongle. Yesterday I managed to fully charge the phone after restoring and configuration and it seemed fine as I achieved around 4hours sot and plugged the phone with remaining 20% battery. Today the battery went dead in below 3hours of sot and it was before 17:00, phone was unplugged around 8:00. This is not bad. This is shocking. I will maybe factory reset and restore everything from cloud, if the battery life won't improve, I will be giving the phone back..I have 6,5h of SOT on Pixel 2 XL which is satysfying. I was hoping to get around 5, but 2.5 is unacceptable.

Samsung is always like that at the beginning. Leave it to do it's thing and then check in a couple of days.

That's not my first Samsung, and I've never experienced that big battery consumption

Started of on my first charges with around 7hr sot, ended with the last two on around 3-4hrs, super confusing. I feel like the phone is draining so much in the background, so if i dont use it i wont get good enough SOT.
s9+ btw. Heavy user, snapchat/reddit gifs etc.

Are you guys using the exynos or snapdragon version of this phone?
Sent from my SM-G920T using Tapatalk

Exynos in my case. 7% batt with 3,5h SOT. That's a huge disappointment

23% with 5hr 18min screen time, 10hrs since charge. Also 3hrs of apple music and 1 hr YouTube over cellular.
I'm really happy with that.

Unplugged for 16hrs 9min. 19% battery. Screen Time 5hrs 42mins.

No complains here. The battery life is not outstanding but it is definitely acceptable.
When i turned on the device it had like 50-ish % juice and it managed to hold for like 6hours. Obviously not 6 h of SoT but just was using it on and off, installing apps, moving data, playing some media, etc...
Now its my first cycle since fully charged and i'm sitting at 50% with 4 hours of SoT. I did not do any gaming tho.

First cycle on my AT&T S9 Plus SOT over 4hrs and 52% battery life is amazing so far.

Well at 11% and got over 7hrs SOT for first cycle not bad at all battery life seems outstanding for first cycle will see how it goes once it settles after a week should get even better.

Early SOT Results
I received my Unlocked S9+ a little over 24 hours ago (US version). After setting it up last night and some this morning, I am finally on my first cycle of normal use. I am currently at just about 4 hours of SOT with 50% battery (see photo). I know it is way too early to measure the real battery performance, but thought i would share my early results. This is definitely on par with what I have been experiencing with my other phone (Pixel 2 XL) and the settings/apps are almost identical.

Standby battery drain
Charging the phone (S9+ Exynos) before bed, removing the charger and letting it drain the battery during the night, with wifi on, viber, WhatsApp & gmail syncing, I get a battery drain for the last couple of nights of 0.6% per hour, without AOD.
At least for me it's a bit better than my Exynos S8+ could manage.

Could it be, based on this post, that the SD845 version has better battery life than Exynos?

Not sure but it's all over New Snapdragon is battery friendly compared to Exynos , Which Exynos eats more battery. Snapdragon has got to the point is better in different ways from Exynos.

I think this theory could be correct from what I've heard.
Someone mentioned having 4 hours SOT and they're at 50% on the Snapdragon. I'm on an exynos and I certainly would only be able to get 2.5 hours to 3 hours max on about 50% battery.
The question is, can the software be tweaked enough with updates to make the exynos more efficient, I wonder?

I am on exynos and have 4 hours en 10 minutes screen time when i am on 50%
The day before yesterday my phone was up fot 1 day and 10 hours and my screen time was 7 hours and 35 minutes.

AT&T S9 Plus Snapdragon as you can see SOT 2hrs and 1min on 72 % ,so battery life is is gonna keep getting better by the time i go down to 10% pretty sure i will hit 7hrs and half to 8hrs , I also get this type of SOT on my AT&T Note 8 Snapdragon , So not sure why Exynos is having battery issues.

hi guys, would like to know if you are happy with the battery life or not.. can you get a couple of days battery life with moderate usage and 4-5 hours sot maybe? that's what I use to get with my xz2c... i know experience may vary from people to people and usage etc but with moderate usage it should be pretty clear what I mean... (messaging, browsing, emails, no games, and such)
and AOD turned on please!

I rarely look at sot but in general, after 4 days, the battery life is perfectly fine. Not stellar but I haven't hit 50% yet after all day use. I'd say easy 5 hours sot simply because I use Strava which is a battery hog while biking and running. With my P2 I'd come home with about 75% or less. With the P3 it's mid 80s and I still last the whole day without a charge. I tend to look at overnight drain AOD but face down so I guess that doesn't count, but I'm either getting 0.5% / hour or 0.6. On my P2 it was about 1.2% / hour. I'll check sot today and edit.

thank you very much sir for your reply so appreciate!
if someone can post also the overnight drain with airplane mode ON and AOD always ON too (that's how I would use it at night), that would be fantastic!

I got just over 5 hours of screen on time yesterday with heavy usage. 6:30AM to 11:30PM.
Adaptive screen brightness set to favor higher brightness. AOD enabled (this turns off when in a pocket or face down on a table, BTW). No gaming. On Wifi for ~70% of the day. Did not top off the charge at any point.

5 to 6 hr on lte. 6 to 7 on wifi. Like the pixel 2

I have only had it for a couple days, but I would never expect it to outlast an Xperia device. Those things go forever! I use LTE all day at work and then WiFi in the evenings at home. The phone stays on vibrate mode from 8am-5pm, and is primarily issued for occasional texts and checking XDA. I leave work with about 70% battery.
YouTube handles the rest of the load from 6pm-10pm. I don't track SOT but the battery percentage drops below 20% regularly with this routine.

Saturday when I put it on the charger at bedtime, it was at 51% with 4 hrs & 10 mins SOT. I thought that was outstanding.

I have super light usage and I get about 4 days. I didn't take a screenshot sadly.

Better than pixel 2 was...6.5hr sot on lte and 7 to 8 on wifi

That is normal. All of these high sot numbers are on WiFi only with special use cases, probably no cellular calls either.

Lol, then you have no worries because you are clearly a light user. ?

It's still early days since I'm doing all the set up still which means more screen time than normal, but the fast charge is ridiculously good, even when connected to a PC.

Battery life is okayish. With normal use like browsing, some videos, light gaming, fb, insta, WA..etc it will go through till the end of the day. I get around 4-4.5 hours of SOT with WiFi, AOD off. I'll test it out more, probably.
