Battery drain when on WiFi - Huawei P20 Questions & Answers

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

[Q] Cell Standby?

Hey, I was wondering if anyone that is on Verizon if their Cell Standby has been going crazy and draining all your battery over night?
I had no problems with the phone at all until 2 days ago where i left it off charge over night and the cell standby was beyond crazy high.

I was wondering if there could be anything from an app that I downloaded (I seriously have maybe 5 apps downloaded) or that Verizon has been doing cell work over night which is trying to find data? I'm not sure and it's really bothering me.
Anyone else having the same issue?
Unless your battery is really draining faster, it is a display bug.

Well it's been happening for a few days so I don't know what to do. I just factory re set the device and hoping the cell standby isn't high again. If it is I'm just going to go replace the phone.

Battery Drain, but NO Wakelocks

I have an odd issue that happened twice so far over the last couple months.
I'm well aware of the common issues that cause battery drains, such as app wakelocks, Google Play Services, wifi scanning, location etc... Sometimes my phone's battery just tanks @ idle, dropping like 5-10% per hour, with nothing causing wakelocks at all. Normally, my phone probably drains < 1% per hour, so obviously it's an issue.
I was able to fix the issue after going into recovery and wiping cache/dalvik and what not, but it's really odd. It seems like the phone sometimes just can't measure the % correctly.
And again, my phone generally drains <1% per hour, and when the issue occurs, I check my phone and I see it tank to like 40% after 5-6 hours idling when settings were not altered.
Does anyone else have similar issues as this??
As you stated above, there are wakelocks. I don't know how you would lose 10% every hour on idle mode. Normal loss is 1%- 4%. Please install a wake lock app such as betterbatterystats and report back with a screenshot or look up what the wakelock means. Majority of the time, it's just a app sucking your battery. If this is a major concern to you however, just factory reset.

Anyway to not have everything off in airplane mode and get less than 1% drain an hour?
I think thats substantial battery drain lol

I posted about what I think is the same issue I've seen here: http://forum.xda-developers.com/showthread.php?t=2589036. Look familiar? Happens more frequently to me than it does to you, but I reboot often due to kernel updates, Xposed module updates, etc.
I hope it's a software bug, but honestly, I haven't seen anyone else complain about it. Until now. I find it impossible to believe nobody else has noticed it. It's impossible to miss.

I've been on Cataclysm rom for a while now and it's very random. Only experienced twice and I preordered my phone (so however long I've had it).
And as to the other posts above, like I said, I'm not a novice to identifying wakelocks... I'm well aware of the typical wakelock issues this phone has, and my device generally doesn't experience this drain. Unfortunately I don't have any screenshots, but basically everything looks normal in BetterBatteryStats, but the battery % just tanks in a linear line with hardly any awakes.
I'm personally thinking it's a bug with the software regarding reading battery %.

Not on this phone no. When I had my HTC one I would regularly get around 0.4% per hour standby drain. That was the best I've ever gotten on any phone except the iPhone.

My HTC One was at about 1%/hr. My Moto X on it's best night lost only 1% over 8 hours but I usually lose 2-3%. My Nexus 5 is at 3-4% overnight. I've seen it do less though. I have to leave wifi off (on both my X and my N5), otherwise the drain becomes more substantial. As long as it's on LTE, when it sleeps, it SLEEPS.

I did last night for the first time, and a friend of mine had it a few times too, but it mysteriously fixed itself... At least it's a while that it doesn't happen anymore

1: Your cell coverage seems to be kind of bad sometimes, it cna cause battery drain
2: Your phone is awake most of the time even with screen off, you should check your wakelocks

Hi thanks for the reply yeah my network is bad in this area never more than 2 bars of signal, I was running wakelock detector on 4.3 but obviously Google stopped the user from being able to read process data. I do have gsam battery monitor installed I will see if that turns anything up. I hope Motorola fixes the battery drain issue soon thanks for your help.

Notice how your battery drain is bad after GPS is used. See the link posted above by the other poster. My posts in that thread refer to GPS as being the culprit. It seems it may be the same in your case.
When you notice the bad battery drain try a reboot. It should fix it until GPS is next used. BTW I have noticed GPS doesn't always cause the drain to start, but it does quite often.
Are you on non-gpe device or gpe.

Hi Scott thanks for the info I didn't notice that I will fully charge tonight and then use the GPS for a little while and then stop using it to see if that causes the drain by the way my phones a standard g non gpe.
A quick update this is today's total battery life with some GPS use and Bluetooth on from 5pm connects to my car stereo.

actually with that signal level I think this is the normal drain, you got quite some screen time as well.

Ah thanks I would have got more but the phone powered down at 10% seconds after i'd posted that, calibration issue I'm guessing.

Did a bit of a GPS test this morning Scott was used for 15 mins then maps was turned off along with data so I had no other battery drain.

My personal experience is that I only get the drain when I have used GPS but I do not always get it when I have used GPS. Basically to me it seems like some intermittent GPS issue that causes the drain. I had it yesterday and rebooted. But today I have tested gps and all fine again - no drain.
Also have noticed after the latest KitKat update (the tiny 9MB update) that at times GPS can't get a lock.

Battery Drain Issue

Hi,
I am facing a lot of battery drain issue. My phone is only a month old . I have updated toemui 5 with nougat. The battery doesn't last for more than half a day. May a little more than that. I'm losing a lot of juice even when the phone is on standby.
I keep closing all apps when I get the message for power using apps. I have disabled most of the apps too from using my battery..
Someone please advice. I also feel that the charging is very slow on my device
Do you use GPS location? Data? Wifi? Do you have strange signal on your SIM?
I found these things that they consume most of the battery.
Do not close just apps but what drains the battery in standby is a lot of wifi, data and cellular..
Try to disable that settings every time you are not useing it.. evan if two sim.. disable the one not needed.. this should help..
But then again I never disable anything and still can go up to 2 days..sometimes one day and having still 40% .. are you on the latest noughat 7??

GPS is rarely on. WiFi is on all the time. Data is usually off..
The phone is a bit quirky when it comes to battery for me. Some days, the power drain is unreal and will lose 10% per hour during standby. Other days, it will sleep all night long and only lose 2-3%. Even stranger, the days when the drain is very high, the stock battery graph shows the phone with minimal awake time. And on the days when the battery is not draining, it will show constant system wake ups when the screen is off for hours. I've only had mine for a few weeks, so I'm hoping it's just reacting to all the apps and settings I keep adjusting and will settle down over time.
I think this issue came with Nougat update... Noone complained with A6..

Many, many users complained about the battery issue on noughat 7. So me to was thinking should I risk to update to N7 or just stay on MM
Couse many users tried it and than did the roll back to MM
So I tried it to and was not having any battery drain
And with the latest noughat version like the B381 I am having or depanding on model it is the B385 or the B387 it not just adds more features like better camera options and functions but it also gives the battery drain fix many already reported that the drain is now gone.. and for me it is evan better battery on B381 then it was on B360.. much better.. like 30% better

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.

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.
