Awful G3 Standby time

So ive been using my G3 for about 10 days now and have been getting pretty bad battery life at work with airplane mode on and only wifi and wanted to really test out the battery last night by leaving it unplugged overnight. I usually keep my phone plugged in overnight but since it was the weekend i was home on saturday and it was in the charger for basically the whole day i decided to test the battery. I unplugged the phone at around 2:50 and took the screenshots below at around 8. I lost 29% of my battery during that time and i was SHOCKED!!! my phone was on 4G however i have really good service where i live and was on 4-5 bars all night. the phone didn't have bluetooth, wifi, nfc... ect active. The phone was on 15% brightness (if that even matters since the screen was off all night). Before i took the screenshots i went into battery and saw that an app called "lyft" was said to use 70% so i uninstalled it before taking that screenshots. I really don't know what i should do because i am rooted and have already installed a tempered glass screen protector. Please help if possible!
Screenshots: http://imgur.com/j3kbWyJ ; http://imgur.com/EZekrFw
Edit: Its 9:37 now and around an hour and a half after i uninstalled lyft. I am now at 68% which is better than last night however still pretty bad considering i had a screen on time since last night of just 6 minutes and 29 seconds. Here are the screenshoot updates: http://imgur.com/azs4SWK ; http://imgur.com/DNZu8n9 ; http://imgur.com/qrz4nrx
Edit #2: Battery life continuing to drain fast i have 59% which means i have lost 9% in less than 2 hours of virtually no screen on time. I am very concerned and don't know what to do? If anyone has had this issue please let me know. Screenshots: http://imgur.com/8nOgVgj ; http://imgur.com/lSywjj4 ; http://imgur.com/KqGYAVK

Looks like wakelocks only. my G3 has a great standby time, overnight with WiFi on i lose 3% or so for 6hrs. SOT is not that good, but the phone Deep sleeps well.
Try removing unnecessary bloat.

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 Sony Xperia XZ Premium'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!

damn no reviews for this lol im just here letting you guys know that the standby battery is amazing went to sleep yesterday at 12am with 69% of battery woke up today at 7:30am with 67% damn my old lg v20 couldnt do that lol

It's quite bad here with standby drain as well. "Phone Idle" is always on top of the battery usage apps and it's probably a few percent an hour, depending on charge of course. >90% it's 1-2% an hour, but that increases when the charge level drops.
Stock .145 rom with storm//'s hack and have greenify running

Standby drain 0,2-0,4 %/h. locked BL, .145, Greenify.

phone idle coming top 3 with 6% took from 100% in about 4 hours! what could be causing that??
phone idle 4:11 hours
screen time 1:50 hours
36minutes of sniper 3d
7minutes playtube player while screen on (plus 20 minutes screen off)
I am on 57% just after 4 hours of use! while only 1:50 hours of them screen on!
phone idle for 4:11 hours took 6% which is a ratio of (1.5% per hour)
not good at all, what could be the problem??
I tried draining to 0 then charge to 100 on a straight charge while phone is off, phone is factory resetted, locked, not rooted, stock rom .119 oreo
what else can I do here?

I don't know but I have the same issue for months... Usually 2,4-2,8% per hour (when screen off!!) and battery stats not showing anything relevant.
I have everything stock, and I am using Greenify since a ~week, now I have 1,5%-1,8% on standby (which is still a lot, but improved compared to the previous situation).
Is really bad because if I detach my phone at 7 in the morning, at 14 I am already at ~80% without doing nothing! That's also means that using it, specially a lot with maps or things like that, I am not able to go farest than 17-21 :crying:

i noticed that factory reset didnt work for me, neither does software repair
so what I did was, flashed .179 firmware, fresh flashing, wiped every thing!
battery life was almost still the same, it got a lil better.
BUT, I am now using stamina mode any time I dont use the phone much, in my pocket, or even if im slightly using it (whatsapp, instagram etc...), I only turn it off when im gaming or watching some thing which is getting me to lose 1% every 4-6 minutes when using the device, and not losing anything when the device is off (as I activate the stamina mode) this should get me around 6:30-8:00 hours of screen time!
also I noticed I had viberation on navigation buttons, I also had face detection unlock and "ok google" unlock, and google feed and a lot of widgets and a live wallpaper, and avg running in the background.
so I disabled all of these useless features as I really dont use any of them (maybe rarely) and i can feel a slight improvement. (still slight improvement over slight improvement makes a noticeably improvement)
so now I unplugged my device at 17:00 at 90% more or less and now its 22:07 and i still got 56% so in about 5 hours I lost 34% while 2:14 hours, screen was on so its very impressive!
I can get to 6:45 hours of screen use which is very very good! im still testing though.

Nah i know its too late to write this but,.
For you all who have a problem draining battery even at sleep try Greenify Donation Package + Powernap xposed module
Even now my xzp still have sot around 6 hours with 15% battery left. With everything enabled like x-reality, auto brightness, mobile data.
Btw i'm using existenz v10 cusrom + DT2W Kernel

Battery drain - device idle - any solution?

Hi all
Had my S9 for a few days now and noticed that I keep losing around 10% overnight while the phone is doing nothing.
I have AOD switched on (Like I used to on my S7 which was fine with battery) and have the phone on flight mode.
If you look at the green line on the far right of the graph is where it is draining at night (image attached above as a link since the image itself is huge to fit in here)
Any ideas what's causing this? Any logs or apps I can use to figure out why it's happening?
Thanks!

Might be worth fully charging the phone (to reset the battery monitor). Then using it very briefly and leaving it overnight. Then see which apps are at the top of the battery drain list?
Mine definitely doesn't drain that bad. Here's a screenshot of mine overnight. I maybe had 5% max.

It should settle mine seems to have done first few days I could see the battery drain I have had the phone uncharged since 0630 this morning and with loads of use I'm on 53% the other day I was losing artery rapidly hopefully update on Friday will sort out any bugs

Ok I'll try that. I have a feeling it's something to do with flight mode since I don't see a drain like this during the day but only after I've switched it on. Weird...

Swipe down on your home screen and where it says power saving. Long press it instead of press it.
Or in device management click battery.

Try the same with Aeroplane mode off?
I dont use aeroplane mode and mine drained 4% in 8 hours last night.

I'll try tonight with "do not disturb" rather than airplane mode. Seems like this is a common issue with the S8 too from googling. I'm guessing it's some sort of software problem. I've disabled location permissions with some apps and did a system update not long ago... tbc!

I have also the same issue with my S9 using airplane mode and lost around 12% overnight...
I have AOD disabled during the night and have a S9 Exynos version.

this must be a bug with the modem or something. some german users are reporting this as well.

Same here, cell standby and AOD seemed to be biggest culprits.
Couldn`t get 3hrs of SOT in a 28h usage period.
A phone restart seems to have helped with the AOD drain, and disabling VoLTE with cell standby drain.
And i just got the update (SEE) so we`ll see how it goes from now on.

So guys to give you an update I manually installed the new system update yesterday and tried to use do not disturb rather than airplane mode.
It drained only about 5% this time which is a lot better! Also I've done around 4h24m SOT so far with still 38% battery remaining which is pretty amazing!
I'm not getting carried away though it might just be a one off. I'll try airplane mode again tonight.
One other thing I also did was to block a lot of apps from using Location apart from Google play services. It's in the app settings then permissions. This might be the main reason why it's better along with the system update.
Again this might just be a one off but hopefully not!!

Hello,
I think the airplane mode is actually the culprit. I didn't enable it last night and the s9 only lost about ~4% over the night. I don't know where we could report this issue to samsung.

Yep defo is. Tried it again last night and lost around 12%

I unplugged my Galaxy s9 plus at mid night. It is now 8am and I have been using my phone for about 20 minutes, my battery is at 94%. AOD is off, battery saver is on. My e-mail did sync during the night several times, so I guess that is not bad. It is about the same useage as my LG V30.

After receiving March update and due to some issues, I did reset my S9+, @01:15 hrs activated Airplane mode and unplugged the charger when the battery reached 100%, AOD is active as well
Woke up @07:30 hrs to find that I lost in 6 hours 12%, the battery is 88%
According to the battery usage, AOD used 4% and Phone IDLE used 1%

There is a problem with airplane mode. I would advise you to switch to do not disturb instead. I read somewhere that it's something to do with the modem software since the issue is also happening with the s8.

I use 2% overnight on airplane mode ( 9hrs - and uses 0.2% per hour as reported by GSAM battery monitor) , I also turn location services off as well.

How do you guys switch on do not disturb mode? I went to sleep around 1-2 am battery at 68% around woke up at 9 am with 46% left, that's some awful drain

Have crazy issues with Oreo.

Basically, got this phone from Amazon UK when they had black Friday deals.
Got the phone, used it... battery was going down really fast. tried to update etc, factory reset. I have the goodix fingerprint sensor and my cpu usage is always at the max. android system, gfmanager etc is draining my battery really fast! I'm lucky to get 4 hours SOT.
Anyone else?

I get 4 hours SOT, BT always on with constant heart measure with band 3. (about 5-15k heart measures per day) And i get about 2 days battery life.
(wifi always on, 1hours weather update on band3 and every time i unlock screen weather update on phone)
If I use only phone on wifi without BT, i get about 5-7 hours SOT, and 4-5 days battery life.
(most of SOT is used by playing games, so most intensive)
i haven't tested only browsing or video watching SOT

^ Still doesn't help me.
I've turned off bluetooth, connected to the 2G tower and Oreo is still terrible with the battery. everything I can tweak to help battery life I have done, nothing seems to be working.
"Android System" and "GFManager" are consuming the hell out of my battery!
Surely I can't be the only one.....

I think GFManager has something to do with the fingerprint sensor, maybe try to turn it off for testing purposes.

I've tried and I can't disable "GFManager" it just won't let me.

Question Battery Misbehaving (Is it just me?)

Just bought this phone brand new and had the sense that the battery was draining pretty quickly. I noticed some weird behavior when charging to full and turning the phone off for some time and wanted to ask if it might just be a software issue. Also had a few more questions.
So the first issue is I saw happened after attempting to calibrate the battery by charging from 0-100% and past 100 until charge current was zero or negative (note I didn't bump charge it). I turned the phone off for an hour and turned it on again and it showed 97% despite me charging it to what I thought was actually 100%. To see if something was draining the battery I turned it off overnight again and when I turned it on it only went down 1% over 7-8 hours. Leading me to suspect a software issue. I used the 60 watt charger that came with the phone.
Another thing I did was try to get a battery health with accubattery. Using the 60 watt charger I'm surprised to see it estimated the capacity as 4400mAh and not 5050mAh. Can anybody confirm if they are getting the same results? (Charged in airplane mode with the internal fan off in a cool ventilated place).
Finally did the Netflix video test to compare the 6s to 5s and they are around the same with the 5s slightly ahead on playtime. Despite me matching brightness close enough that it was indiscernible which display was brighter. I played the exact same video synced and looped on both with audio off and the 6s hit about 14.5 hours at roughly 33% brightness.
Was wondering if somone could run some accubattery tests with the stock charger and see what you get?(you'd have to reset accubattery and charge from 0-100% and past 100% until charge current is negative).
Anyone else having battery wonkiness like this?

Can anyone please do me a solid and check average and max battery discharge rate with accubattery? I'm trying to figure out if I got sold a lemon.
With brightness set to the following at 60 Hz and wifi off.

And does anyone know if accubattery directly reads discharge current or only estimates it?

Hi. Maybe i am not really

This is from my rm 6pro global version result for your reference. Hope it helps for the comparison purposes. Tbh, i never crack my head off thinking about this overnight. But if you just bought the 6s pro and installed this apps to the phone, let it study your usage behavior maximum for a week to get a better result.

I've been using for months and this part is what i am concerned the most. Looks scary though?

Hey man. Thanks so much for looking into this for me . This is quite helpful
What refresh rate is your display set at most of the time? And do you usually have auto brightness on or is the brightness shown in your screenshot around where it usually is? Do you game heavily daily?
Your battery usage seems a decent bit higher than mine. But I'm glad to see our capacity estimates are in the same ballpark.

Also. I noticed if I charge my phone with the bundled charger. After I turn it off for a few hours and turn it on again the battery % is always suddenly 5 to 9% lower than it was when I turned it off. Does yours do this too or is my battery a dud?

That's not how batteries fail.
Something in the background is draining it.
The charge current draw can vary widely depending on charge state and temperature.
Real time charging current readings are only valid for the first second on Accubattery as once it updates with the display on that will skew the reading. You have about 1 second until Accubattery refreshes so have that window open and look fast.
The power controller won't/can't use the same charging curve with the display on... and will charge much slower. It ramps down the charger current draw to protect the battery when the screen is on. Avoid using while charging.

Most welcome. It is coincidence that i taking a walk in this forum and saw your post, so it is like my responsibility to respond at least as for your reference. Really glad that i can help you on that.
Refresh rate 99.9% of my usage will be 60hz to get my phone on long marathon for whole day. But i am charging the phone quite frequent as I am addicted to Asphalt9 and i have to settle down with the addiction.
Most of the time i would prefer auto-brightness but would make some adjustment depending on my surrounding. Dragging as your brightness level on your post for your comparison with mine.
Yes. I am addicted to Asphalt9 and keep playing for almost 10 hours per day. And forcing me to keep my charger set standby in my bag to be use whenever it required.

Just for my own theory. Our phone is like car. Whenever it started, it will trigger all system around the 'engine' and forcing some energy to launch all the applications at the same time before you start to use it. But it side effect is painful to see you battery getting drop that much than giving you a little pleasure for a kickstart of the day. I tried once or twice to check on that kind of situation earlier, it dropped within 1-2% only. But the stranger thing i observed, after it got fully charged, and you unplug the charger, you may see it drooping 1% after few seconds. Still be a mystery to me.

I am totally agreed with you as to test the charging speed, the apps does remind us to turn off the display and check after few moments then you can see the charging process is functioning based on when the charging started & for how long was the screen being asleep while charging.
Psst~~ i have a bad habit by using my phone while its charging as i did right now to reply your comment here.

It's better to do brief midrange power cycling (40-72), Li's like being cycles like this. It reduces the wear on them a lot. Only takes 10 or 15 minutes.
So when you take a break, let it charge.
You can listen to music on bt with Poweramp with the screen off and not effect the charge curve.

Another thing i would like to seek your advice, does the 'charge separation' is really useful while gaming? Does it affecting our battery life if being enable frequently for a long hours gaming?

High discharge rates and back to back fast charging is hard on the battery.
Best to give it some rest breaks especially when you start using more than 10%@hr.
Expect a battery lifespan of about 1-2 years on a heavily used device.
I watch a lot of vids on my N10+ and will replace the battery after about a year, sooner if needed.
It's simply not worth the risk of damaging the device over a $16 battery.

I see..and hell yeah to look for a rm6 pro battery is not an easy thing and not always ready on stock.
Fyi, i have some OCD symptoms which i could not see any less than a full charged battery capacity before i am going out. Is it affecting to our battery life span if it keep full charged even my battery still got more than 50%-80%?

Watch a tear down for it to see how bad it actually is to replace the battery. Availability will hopefully improve.
In the daytime if the battery has 70% or more of a charge on it, I don't top it off.
At night if it's at 50% or more I don't give it a partial charge until I wake up.
I can charge whenever I need to, so I take advantage of that.

My battery drops when the phone is off (not screen off, literally phone is turned off) it drops the most after a fresh charge and if I repeat the process it drops very little. Its almost as if it thinks it's charging more than it really is and then drops quickly to the real value?? But here's the thing. It also happens when I do a complete 0-100% charge and then overcharged it until it shows negative charge current. Like the battery should be full at that point shouldn't it? Or is android thinking it's full when it's not and completely cutting current? Is this just a software issue as I suspect?

Ah

Most welcome. It is coincidence that i taking a walk in this forum and saw your post, so it is like my responsibility to respond at least as for your reference. Really glad that i can help you on that.
Refresh rate 99.9% of my usage will be 60hz to get my phone on long marathon for whole day. But i am charging the phone quite frequent as I am addicted to Asphalt9 and i have to settle down with the addiction.
Most of the time i would prefer auto-brightness but would make some adjustment depending on my surrounding. Dragging as your brightness level on your post for your comparison with mine.
Yes. I am addicted to Asphalt9 and keep playing for almost 10 hours per day. And forcing me to keep my charger set standby in my bag to be use whenever it required.

Ah I see. Asphalt 9 + auto brightness explains your fast drain. Still it make me worried my 9% per hour drain is too unusually high.
It baffles me that the Redmagic 5s wins the Netflix endurance test vs the 6d

That's not normal. wtf?
Lol, it has a negative attitude
No idea what's causing that but the battery percentage indicator sounds useless.
Return it if you can. May be a mobo failure in progress...

I did it again this time at 63% and my battery went up to 65% while the phone was off overnight. Only to drain to 62% over the course of 20 minutes with the screen off .
And whenever I fully charge and do a voltmeter hard reset the battery always drops about 7% after the reset.
I think something is very wrong with the battery meter calibration.
Why do you think my mobo is failing?
