Cell Standby battery drain WiFi only

I've had my p8 max for about 3 months and after a few updates I've noticed I get huge battery drain by cell standby if I leave WiFi on in standby mode. I have the new update BO26 and while it seemed to solve the issue for a while after one charge cycle its back again. Wanted to know if anyone else is having this issue and if so what can be done to resolve it besides waiting on another firmware update. I've cleared cache and factory reset numerous times only to find out the problem returns. Thanks in advance. Oh yea, my phone isn't rooted which probably will also be a solution but as of now I want to avoid rooting.

MT7-TL10 Battery Problems

Hi,
I owned a Huawei Ascend Mate 7 Gold 9 months ago, and I was very happy because I could use the phone for more than 2 days withouth charging. But recently, the battery started to drain VERY FAST .
For instance, if I go to sleep with the phone at 100%, when I wake up (8h later) , the battery is at 70% or less. With my investigation, I tried/found that:
-The problem is not caused by deep sleep mode, or at least "CPU Spy" shows that the phone is able to do it.
-I tried wipe (factory reset/partition/cache) with no results.
-I calibrated the battery but the problem persists, also I tried charging with 1A charger.
-"GSam Battery Monitor - Root" shows that 47% of the battery goes to "Android System" and another 20% goes to "Kernel (Android OS)".
The issue started at the last week, and the first thing I did was updating Lolipop (I was using it for more than 4 months) to Marshmallow 6.0 (B561). I don't know what do to now, ATM I'm underclocking the CPU, but that's a temporally solution. I always take the battery with a lot of care, I don't know why is happening this.
If someone could help me, I will be very thankfull .

same here
i have exactly the same situation with u and couldn't find a solution yet.

battery issues too
what firmware you running? I have an EU version of the phone, updated to 5.1.1 and it was dying fast. I then updated to 6.0 Malaysian rom from their website and it started to do the 2 day life. However the phone seems to just freeze and sometimes just switch off, so I am thinking of downgrading and then see if its the software or its a hardware failure. I have warranty

I couldn't find any solution yet, so I'm going to downgrage to the 4.X. I don't see benefits from Marshmallow update, also I can't hide the taskbar, so...
Actually I think I'm using CH version B561.
Edit: Fine, I can't find a downgrage pack for my version.

Insane Idle Battery Drain

Hi,
I'm getting some insane levels of idle battery drain recently. A bit of background,
- US Stock
- Rooted
- SuperCID
I was having this battery drain everyday for about 2 weeks, so I wiped my phone and started fresh. Since I did, I've been slowly introducing only a few apps everyday, and the battery was perfect until today.
All I did since yesterday when it was good, was tether to my laptop for an hour, and when I noticed a few hours later that the drain was back I removed the Bluetooth pairing completely. But the drain remains.
My phone sits in an awake state with the screen off for 99% of the time.
Here are some screenshots from Better Battery Stats and Wakelock Detector which don't seem to show much apart from a Google sensor.
http://imgur.com/a/eKqjl
Desperate for help because as much as I love this phone, with this situation it is barely usable.

Some more screenshots. Wakelock Detector and Android Settings.
The only red flag I can see is something called "Significant Motion(12)" which was awake for almost 7 hours. But I've been googling this and not finding anything about it.

Another screenshot now that I am at a computer - this is from a Google Historian report from a bugreport I just generated.
Something labelled "Abort:noirq suspend of c171000.uart device failed" woke the kernel up 89696 times. Wonder if this is the "significant motion" sensor that BBS is reporting?

I have the same problem.
It's started 3 days ago and i don't know how to fix the problem.
I hope that htc would fix this problem on this weak.
If someone know how to fix this problem until htc do something, please reply.

I don't even know what the problem is - so how do you know you have the same problem?
I'm not sure this is a problem for HTC, because my phone was perfect for 3 days after resetting it. It only started again last night. If it was great for 3 days and started on the 4th, odds are that it is something about my set-up rather than a problem with the stock firmware.

I have not changed anything on my phone and the problem is surprising.
Last week I did not install apps or add files.
I also have Watsapep at the top of the table in the utilization of the battery.
android 8.0.0
software number 2.42.617.1
not rooted
stock rom

Try disabling google apps one by one
also try using your phone without wifi

I already tried disabling app by app when it first happened, and did this over 2-3 weeks basically going through all the main suspects and Google Apps.
About to go to sleep tonight, I am going to try,
1 - turning off wifi and Bluetooth and charging the phone to a decent charge level
2 - force restarting the phone after removing it from charge
3 - leaving it on the bedside table untouched until I wake up in ~7 hours
Someone with a U11+ said they need to force restart after charging, so it’s worth a shot right?
Also just posted this about the sensor in another thread. Anyone else having trouble, would appreciate if you could also try these steps,

The ways I stumbled on this were,
1. Better Battery Stats
Under Sensors, you'll notice Google Play Services with a high percentage. Click/press it and you'll see a listing for "Sensor: Significant Motion". This to me indicates that the device thinks it is being moved and refuses to go into Doze mode.
2. Google Battery Historian
Charge your device and let it drain for a while. Then connect it to your computer and take a bug report using ADB - adb bugreport bugreport.zip .. visit an online version of the tool here https://bathist.ef.lc .. then upload the bug report. Under "kernel wake up reasons" you'll see "Abort:noirq suspend of c171000.uart device failed" with an abnormally high number.
3. Take a dumpsys of battery stats
Using ADB, after running your battery down a little, run - adb shell dumpsys batterystats > batterystats.txt .. read the file and you'll see the line I pasted above in my last post.
Would be interested to see if someone suffering from the same symptoms could try this and see if they get the same things. U11 or U11+.

With the associated battery drain I assume?
I did this overnight which actually seems to have worked,
1. Switch off Bluetooth and WiFi.
2. Charge phone (it got to 76% when I decided to sleep).
3. Remove from charger.
4. Force restart with vol down + power
Today I’ll experiment to see if I need to do the same 4 every time I charge, or if maybe it is related to only a few of these.
Overnight my battery lost only 5% in 8 hours.
When I get to work, I’ll do a battery dump to see if the noirq error is still present.

Guys today I update my google apps and the problem gone!
how your phone after the updates?

Still there. Seems to be related to charging my phone whilst Bluetooth is on.
When I disconnect from charge, I get battery drain until I charge again with Bluetooth first turned off, then restart the phone.

Found my culprit to be related to Garmin Connect, Fenix 3 watch BT connection.
Could be related to bad firmware.
Edit: Found this same error in my logs a week or two ago when I was trying to track idle drain and lack of deep sleep.
Seems to have disappeared when I disconnected my Garmin watch.

Last night I just had the first occurrence that wasn't related to Bluetooth.
The drain happened despite having Bluetooth turned off when I charged the phone, however I didn't reboot either (and haven't been doing so unless I was trying to get rid of an ongoing battery drain).
I think until we hear of a new firmware release, I'm just going to go through and turn Bluetooth off whilst charging and then restart my phone when I unplug. A minor hassle but at least a working fix.

I had the exact same problem (Significant motion) not allowing my phone to go into deep sleep. For me, just a restart helped from what I remember. Haven't seen this issue since past 4-5 days since it last happened.

I have the same problem with battery drain since the last security update. I am able to fix it temporarily by disconnecting from my huawei smart watch. I will try disconnecting BT while charging and restart after it.

Got a security update today. Hopefully this will fix the drain.

Hello
the u11+ 1.24.401.7 update was just pushed, it is said to address standby issue, my battery dump after reboot no longer contains any reference to, Abort:noirq suspend of c171000.uart device failed
Also early this week a Chrome web view update was pushed in playstore which address issues from Google's side

Severe battery drain on s10e. Any suggestions or solutions?

I've been using the phone for two weeks now and the battery drain has gotten pretty horrible the past week. I charge the phone up to 100% and leave it off the charger as I go to sleep from 1am - 9am.
I wake up and my phone has 70% battery left with wifi/data off. [Battery drain](https://i.imgur.com/VkAcAqd.jpg) [Google battery drain](https://i.imgur.com/qjxMkN2.jpg)
Does anyone know what I can do? Is there an app with which I can check on what's draining my battery?

You can check which apps is draining the battery.
Just go Setting, then search for "Device Care", then hit "Battery" -> Battery Usage

All S10 phones have a bug that is causing them to not deep sleep when screen is off, causing poor standby performance. This is caused everytime you receive a VoiP call, so after you receive one, just restart the phone. Being caused a proximity sensor bug.

Try off Biscuitby feature

Try to wipe disable Google app and check battery consumption. If problem persists, try to wipe cache from recovery and if necessary do a factory reset, 30% battery drain in a night without network connections is not normal. If all attempts fail better go to Samsung assistance to change the battery

7hrs: 10% when sleep, wifi on. Not good but I think it is not too abnormal. I think, samsung still have a lot of bloatware!
But on screen I thnik is OK: 5-6h mixing, 3000mA battery on a strong SOC, it's normal. My back up Huawei GR5 2017, 3400mA, it is the same time!

This solution was posted on the S10 forum and certainly helped me.
There's a bug that stops the phone from going into a deep sleep mode post making a call (audio/video) on apps like WhatsApp, Skype et al. The solution for the time being is to reboot the phone once before going to bed. I tried a lot of other things but had a ~2% hourly standby drain which reduced to <5% overnight after figuring out this solution. I have both WiFi and Bluetooth on at night.
You may try to play around with the battery saving tweaks in ONE UI but nothing worked as well as this has. Hopefully there'll be a more practical fix to this soon.
Cheers!

Being as this affects voip calls, does this mean wifi calling is affected too? I mean, that's technically voice over IP.

I tried to debug battery drain using Battery Historian. I noticed that the phone does go to Doze mode completely, but for some reason, CPU stays awake. I'm still new to the tool, will try to find out more about why CPU is kept awake all the time.
I get battery drain regardless I make any VoIP call.
Another issue I noticed is PUBG lags horribly on the phone. I tried different combinations of graphics settings, the game was still lagging.

Just tried pubg...hdr +ultra runs ok for me. No lags, maybe sometime stutters for a sec.

For the first launch, the game runs very smoothly, lag starts after that. The more I play, the more lag I get.

Putting the phone on battery saver mode barely drains any juice (Medium Power Saving mode), seems like it's just a software issue and not hardware specific issue.
By the time Samsung releases any fix, we might have to live with this one.

Since the update this last day or so, my battery is lasting way better than previously.

Which region you are from? Is your phone unlocked? Is it Exynos based?

Europe region, unlocked with Exynos.

What update? Can you share the info that came with it? My SM-G970U1 is still on Feb. 1, 2019 patch. Although I don't have any problems with battery drain, pulled out two screenshots lately, both over about 12hrs period, one was with cellular radios on and the other just an airplane mode:

It's mostly Exynos people or the Sprint USA models \ service. No one else is having it really.

Got the March update. Exynos version. Battery drain seems a bit better at first glance. But it's not been long since the update. So not completely sure.

Got the phone today and the battery sucks lol and got an update today as well

My Snapdragon S10e never gets less than 4 hours of SoT under the heaviest use (I am constantly messing with settings, installing\closing\uninstalling apps, etc etc)
If I use it "regularly" just browsing Reddit and such, with a normal phone signal, I get 6 to 9 hours every time.
I don't use dark mode until Sunset.
I leave NFC/Bluetooth/Location on at all times.

Battery drain when on WiFi

Hi!
My Huawei P20 is draining very fast when connected to my wireless network. I get like 20-30% drain overnight, which is huge. When using mobile data I lose like 4-5% (when I first got the phone I was having this percents on wifi also, after some time the drain started to happen) which I think it's pretty good.
Has anyone else encountered this issue?

Same problem here. I am on firmware 9.1. 0.325

I still didn't find a fix for this. There are some times when the phone works well, and others when the battery drain fast. If the phone runs out of battery and closes, when I charge it, the next couple of days it drains fast on wifi, after this it works well again.
It is a software problem for sure, but don't know what is causing this. My firmware is 9.1.0.371

I think the optimiser switches off WiFi and there is a reason for that
