Light use endurance - Samsung Galaxy S9+ Real Life Review

Once in a while, when your significant other yells at you, you might use your phone a bit less. Rate this thread to express how the Samsung Galaxy S9+'s battery performs under light use. A higher rating indicates that the device goes a long time when you're using the phone sparingly: no gaming or video/audio streaming, light web browsing, some calling and texts, etc.
Then, drop a comment if you have anything to add!

It's looses about 1.4% /h when it's not plugged in. Its slightly better than average. Had phones that lost about 0.5% when not in use.

do you have AoD enabled?

First screenshot: of model no G-9650, snapdragon ,dual sim, available locally .
Second screenshot: of model no G-965F, Exynos ,dual sim, bought off eBay for custom ROM support .
Third screenshot: settings used on both the models and my conclusion.
Hope this helps the forum users

I never did a standby drain test before last night. When I went to bed at 11:30 it was at 100%. I left it unplugged over night, and had 95% this morning at 6:00 when I woke up. So I lost about .77% per hour., which I consider pretty good. I do have it scheduled to turn AoD off overnight so I'm sure that helps.

battery life

anyone feel as if their battery life sucks? I do have 4g on at all times but I didnt think it would make that big of a difference in terms of battery life.
See my post here:
http://forum.xda-developers.com/showthread.php?goto=newpost&t=839935
Try installing a monitoring app and see if your init process is hitting the CPU hard. I haven't heard from any other mt4g users with the same problem, but lots of.desirehd users have it.
I also have seen my suspend process eating 50%+ CPU when the phone is locked/screen off. Haven't found a fix for that yet though.
I'm getting a full 24 hours of heavy texting, moderate phone calls. Battery life is better than my magic... im having no issues.
Yes, I woke up this morning and my phone was already blinking and battery is on 8%. I left it overnight with more then 60%
A big problem also is that SetCpu cannot force the scale. If limit to 768 Mhz it still scale to 1024. So not I am sure that my ScreenOff profile with 245 Mhz DOESN'T WORK!
THAT'S SUX!!!

Weird I leave my phone at full overnight and its still at full when I wake up.
Try disabling the preflock that might help before I did that it wasnt scaling properly now afterwards it is.
Sent from my HTC Glacier using XDA App
I have frozen a few apps and use advanced task killer every time i start up 9a lot of apps come on at start-up).
The result is pretty good battery life. I have only gone dead when I had a few apps (like GPS navigation) running in background and forgot about them.
I'm having 0 issues with my battery. It easily beats out the battery life on the Samsung Vibrant I had.
I'm having issues too. My battery life today was 40% at 1 PM, and when I left this morning, it was full. I hardly even used the phone except to check email :/ I have brightness on auto and wifi off. Not sure what the issue is.
My battery life has been really good. A typical cycle is charge to full and disconnect power at 10:00 pm. Up at 6:00 AM, battery is still on 100%. Today my use has been moderate to heavy. It's now 2:30 PM and I have 68% left. I typically have around 30 percent left when I put in back on the charger. I'm happy with that.
Wifi, Bluetooth, GPS, etc., are kept off until I use them. I do however leave Background data and Auto-sync on all the time.
I turned on USB Debugging as recommended and my battery life is much better. Right now it hasn't been charged in 9 hours and is at 79%. I've downloaded 2 apps, updated 3 apps, sent multiple emails, light internet use, and 3-4 calls. I'm unrooted and don't use any task killers.

That's awesome. I'm going to turn on USB Debugging mode and see if I can squeeze a little more juice out of it.
I have had intermittent battery-drain issues too. On Saturday morning my battery went from 100 down to 76% in a matter of an hour or two with hardly any use. I did a restart and it seemed better. I've also gotten into the habit of restarting my phone once a day, right before I take it off the charger in the morning. I've turned off quick boot, which I read somewhere in the forums can affect battery life. It's been pretty good the last few days. I'm at 68% now off charger for 9.5 hrs with moderate amounts of wifi, web browsing, email, and 3G network usage. I'm new to android devices so I don't have much to compare that to, but it's working for my schedule.
heavy user - fully charged phone at 7am ... start using after 7:30am
check emails, fb, txt, barely to no calls.....phone will be down to about 20% at 1:30~2pm....
yes the battery is lame...but this is a known issue with HTC...the 3.8 screen drains a lot of battery also the constantly searching for HSPA+ and 3G...
I do notice when screen is off....this phone still drains battery !!! bad =(
left over night at about 65% left in the morning I got red blinking led saying phone is below 10% .... 50% gone!!!
I think restarting the phone after a full charge is a good idea....also maybe turn off quick boot?
*update* yes I found that when you have a bad signal and it's jumping between E and H ... this eats up battery
also installed Advance Task Killer (for froyo) this helps~ now from 8am my phone can last until about 4pm getting about 3~3.5hrs more life
Mine lasts all day with everything on, playing games, email, text, etc, etc.
It is great, best phone I have had. Not sure what the issue is unless it is root.
It depends where you live.
If you get a good antenna signal, your battery will last.
At my apartment signal is low, so phone is constantly between UMTS and GPRS, plus phone is trying to hold H, so that drains the battery.
My signal strength parameters:
between -101 dBm and -107 dBm (where -110dBm is the edge of the signal/loosing signal)
3 asu and 7 asu

P20 Sudden massive improvement in battery life

My wife has had the P20 from the week it was released in the UK. The battery life has been really poor, she is what I would consider a light user on a 4GB contract which she rarely troubles and with a tablet for use at home. She has taken to carrying a portable charger with her to make sure she got through the day. I had checked for any obvious drains, even turning off bluetooth, gps etc. But from a full charge in the morning, she would struggle to have any battery left by the evening, compared to me (a slightly heavier user) having about 40-50% left on my Samsung S9.
However at some point in the last week something has changed, she is suddenly going to bed with about 60-70% battery left.
Anyone else had similar? Has there been a significant update recently (to either the phone software or some other app)?
Craig
My mate 10 after a few updates, i actually use my phone to work, work 8 am to 6 pm get home and i forgot to charge the phone last night, woke up with 72% battery and was wondering if i should bother charging.
I think it has to do with the npu
I experienced the same after the last update. Before the update it would not last more than 4h sot with 1h voice calls. Now i can get 5h sot with 1.5h voice calls and still have like 30% remaining.
i have experienced increased temperature heat. dont know what is causing it.
Same here! But I just noticed it last night before going to bed (had it on full charge), woke up 8 hrs later and the battery only drained by 1% (only Wifi is on). Not even sure if the update was even downloaded without me knowing. But before this the battery for me was performing quite well, coming home in the evening with still 40-50% left.

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the OnePlus 6T's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
10% drop in 8 hours in this video:
https://www.youtube.com/watch?v=ZgtpvkGRr4k
Can anyone confirm? Does standby suck?
Sleeps well. I'm 21 hours and at 65% off charger. 2.7 hours screen on time.
Deep sleep cpu speed is 76%
Make sure you don't have things eating your battery with screen off
My standby has been great. Usually 5-8 percent drop in a 5-7 hour window. Way better than my V30; that thing would eat up 15-20% every night.
Mine has been at 3% drop per 7 hours I'm asleep. I don't know if it has anything to do with DND being on but I was also getting the same drop with my P2XL.
I have been noticing this everyday for the past week. And almost every single time I see about 4-5% drain in about 8-9 hours which is pretty good.
This is on WiFi. So if you're on mobile data there might be a slightly higher drain.
Current status: In deep sleep for 86% of screen off time.
I've also noticed 4-5% drain in about 8-9 hours on WiFi and DND. I'm happy.
Only lost 3% overnight, including picking the phone up and using it a few times.
Not on wifi mine went from ~40% to 3% also my alarm didn't go off. Alarm was set at 545 woke up at 630 and when I picked up my phone to check the time that's when the alarm decided to go off. Nice feature ignoring alarms to save battery.
Is it good enough?
My battery stats are messed up. Battery % goes up even when I'm not charging.

How long have you been using your phone and what's the lowest battery percentage you've hit?
Sometimes it helps to let the software recalibrate the battery by charging the phone to 100 and going all the way down to 0 and then charging back to 100.
I generally lose about 1% every 2 hours overnight. About 1% every hour in the day (When wake my phone up every now and then)

Is it one plus 6t bro?......actually last night my screen on time is 8 hr 17min or smthing.......bt not this much like urs .......what features u disabled to save the battery?
Light use on this thing is crazy. And by light use I mean still using it for over 2 hours a day I can still eek out 2 days without charging.
I'm really unhappy with my battery drain. I see about 2% per hour when I set the phone down and sleep.
I have a Gear S3 paired, two sim cards, and email notifications for about 8 email accounts. But other phones I've had would drain 1% or less per hour under the same conditions.

That's a lot of drain right there. What other phones drained less with 8 accounts syncing and a paired watch?
Mine also has worsen with the new update, and the fingerprint sensor also got slower than the previous build.

Question Overnight battery drain issue

I am totally in love with my GW4 (Classic 46mm Model) as it's my first smartwatch but there is still one thing that bothers me, the unreasonable battery drain overnight. I charged up my watch last night, put the watch on my desk, came back in the morning and saw about 10% battery drain in 8 hours! That's insane considering the fact that I've disabled everything and even enabled battery saver, I thought after all these years I can finally get a full fledged Wear OS smartwatch and be happy with the battery but Wear OS is still the same OS as it was.
I've got the same issue. I thought it was the sleep tracking but I was wrong
And the funny fact is that the battery life is reasonably good when you actually using the watch, but as soon as you put it away it starts to drink juice weirdly, looks like there is no deep sleep kicking in no matter what, even disabling everything and enabling airplane mode.

Which version/size do you have? How many times have you fully charged the watch? I have Classic 46mm. My battery drains 4 -6 % during the night. I have watch on my wrist when I sleep. I always put watch into bedtime mode before I go to bed. I don't disable anything or put on power saving mode. I think the bedtime mode simply turns off notifications and stops watch face from automatically turning on.

Oh sorry for not mentioning it, It's the same as yours classic 46mm. I have the watch for almost 1 week now but I always charge it whenever it gets to 50% so it's a half cycle charge. Do you think I should let it fully discharged and recharge it for a full cycle?
I have the non classic 44mm LTE and I have always used bedtime mode and I've tried nothing all the way to disabling everything and enabling battery saver and still lose quite a bit at night

It seems to me that the battery lasted longer after doing some full cycle charges but I could be wrong. I definitely have seen improvement in battery life since the first few days I had watch. Not sure what it is.

How do you know it was not sleep tracking?
For me, I went to bed yesterday with almost 100% battery. The overnight drain was 15%, flight mode enabled, good night mode enabled and spO2 while sleeping on.
My watch is 40mm, BT modell.
Tonight I will try only the automatic good night mode.
What about Bluetooth when my phone is in airplane mode? Will it consume more battery searching for the device? My wifi will also be disabled in the night...
I am seeing this same thing
13% drain with airplane mode, good night mode, and battery saver modes on.
13-14% drain with battery saver mode and good night mode on.
This is for an 8 hour window.
Using the watch during the day, the battery does seem to last longer and I don't see the drain, even when using it to track workouts and such.
Last night my battery used 11%. I'm not sure what the difference is. I know I have been in the 4-6% range in the past but I always do not pay attention. Possibly related to how fully charged the watch is. Why do we think 10% is bad? I did a search on-line and I have to say that 10% seems very good compared to some other watches. The reality for me as that I'm typically getting 2 days plus on a charge unless I'm heavy on GPS. Currently I'm at 50% and I charged the watch 1 day and 9 hours ago. I came from a GW1 which had significantly more battery time but I'm still very happy with the GW4.
My drain is 20% overnight - despite watch being in bedtime mode.

If your watch is on your desk and turned on, it's constantly searching for your wrist. If you are not wearing it, turn it off.
I have the same issue about battery drain.
I lose between 15-20% each night with everything off (no SpO2, no snoring, etc)
I have the LTE 46 classic model
But based on people and comments I'm guessing the issue comes because I'm not using a Samsung phone and bed time is not synced with the watch and is still "online" all the night
Geez I thought my 3-5 percent drain was horrible. I have the 44mm Bluetooth only model. The first night it drained horrible but I had every sensor on. I noticed I got much better battery after disabling location. I've had mine paired since 7am this morning (it's now 3pm) responding to texts, wifi on and using Spotify on it at 75 percent brightness and it's at 79 percent now. Maybe I got lucky or something? The only sensors I have are the step counter as well as heart rate when resting more than 10 minutes and I never like to use battery saver mode on mine
Second night and I got about 20% drain overnight with everything turned on. I got a similar battery consumption like adj998. Spotify on first place.
I will try do disable GPS tonight and see if anything changes, but I guess it's a normal behaviour. One thing I could try is to turn the spO2 sensor off.
Read somewhere that unlocked ADB is the culprit. So I have unlocked it.
Let me watch how it helps my 20% overnight drain.

Interesting. I'm betting that this drain is related to certain apps as well. When I did my post yesterday about the 11% drain the previous night I noticed the Altimeter app was listed at 4.5%. I immediately uninstalled this app. I had used it once the previous day and apparently it was still using battery. Results: much battery time last night. I would say 3%. In fact, when I looked earlier this morning I still had 41% battery. Yesterday morning I was at 50%. 25 hours and 9% battery used. I have not been very active these last couple days (long days at work). Still putting in about 5,000 steps a day. I have notifications on (gmail, texts, meesenger), use bedtime mode, spO2 sensor off, and do not have watch always on.

Read on Reddit that altimeter drain was a known issue, in earlier models as well.
With people that are having excessive battery drain on their watch: are there any apps which are listed in Wear app -> Watch settings -> Battery that seem like a high percent of battery usage?

Question Power off/Battery drops

I charge my phone to 90% or 80% each night, power off, and go to sleep. The next morning when I power on the battery has dropped 2%. I would appear the phone is doing something when the power is allegedly turned off.
What's happening? Is there actually a way to turn if OFF?
just put it to airplane mode and compare it.
Okay. First I'll do A/M with power on. Battery drops just like at night. I'll do A/M with power off tonight.
and why u not charging overnight
Uh, I don't won't to. It isn't required. I charge it to either 80% or 90%, power off, and go to bed. Why would I want to charge it all night? Last night I put it in airplane mode, charged it to 90%, power off, and went to bed. I turned it on this morning and it was at 88%. I'm just curious what it's doing overnight when it's in airplane mode and supposedly powered off. I don't know that it matters but I've had the phone since August 16th and I got it new.
than get use to it
I'm just curious. I contacted Sony Support today but since my issue isn't really a problem they didn't have much to offer. They were very courteous, though.
2% is "NOTHING" for an overnight drain. Please note that power off/on also consumes considerable power as it puts a load on the processor as it has to unload/load all the processes during that. My Sony phone loses 5% on an average per night and that is completely acceptable as it constantly works in the background (some apps keep refreshing every now and then, I also have poor network reception so that's also a consideration). I'd say: don't sweat too much and your phone's just fine!
On a side note, I also have a Samsung S22 Ultra that has an average 13-15% drain overnight.

Thanks. I wasn't worried as much as curious. Since I don't do games, music videos, or Facebook my battery isn't a worry. Just a curiosity. If I lost 15% in a night with power off I'd wonder if my phone was moonlighting as an Uber driver.
