the battery is drained twice as fast #1809

Open Free-Inside opened 3 years ago

Free-Inside commented 3 years ago

Steps to reproduce

I don't know what produces it

Expected behavior

the battery is draining normally (about 2-3 days)

Actual behavior

the battery is drained in less than 24 hours with moderate use

Logfiles and additional information

even with the latest RC the battery still drains fast, even with several reboots. To be sure I reinstalled UT in RC with the UBports installer without the wipe option, and it didn't change anything

mfoucrier commented 3 years ago

Since the last update, OTA-18, the battery of the Meizu Pro5 is draining almost 2 times faster! I have the impression that the BQ 4.5 has not been affected? Observation made since a few weeks in usual use.

BQ E4.5 is also affected according to a user in my family ;)

I don't think on my OnePlus One it's the same situation, but indeed on my BQ M10FHD the battery goes down in spurts, and a Kworker command comes back regularly and uses a lot of CPU like on the link pictures, I thought it was my battery

Free-Inside commented 3 years ago

On my OnePlus One there is Binder and Sensors.qc which are used all the time, I have checked several times, I even monitored it for 10 minutes and it never stops. Is this normal ? And could it be that this is what is preventing the deep sleep and therefore the battery discharge ? screenshot

p3nguyn commented 3 years ago

I have a similar problem with my E4.5. If I deactivate Wifi and mobile data and do a reboot after that the battery life is normal (ca. 2-3 days for my usage). Once I activate network connections it may take a while but at some point the battery drains very fast. I can even feel that my phone is warm. The battery emptys within ca. 10-15 hours. What happens if you deactivate network data and do a reboot? Is the battery life normal again?

Free-Inside commented 3 years ago

I did this without restarting the phone and yes the battery consumption is back to normal. I had done some testing to try and identify where the problem might be coming from.

Which does not change the over consumption :

Normal consumption :

Overconsumption cannot come from 3G or 4G research because even without cellular data with wifi and without notification the battery discharges more quickly. But there is something on the network in wifi and 3/4G that consumes the battery and/or prevents deep sleep

Flohack74 commented 3 years ago

Please try to find out the process that consumes all CPU in this moment, when the drain is high and when the phone feels warm: Open terminal, rotate to landscape and then type top and lets see what you can find :)

At the moment my phone does not feel hot but the battery drains way to wast anyways. Here is the requestet screenshot: grafik

And here you can see the battery-graph: grafik At about 17:00 I turned on the network connection.

Flohack74 commented 3 years ago

Humm that does not give much results. Maybe modem does not go to hibernate anymore? I have no clue if its not a process actually

p3nguyn commented 3 years ago

Now my phone feelt hot. grafik

This is the overview of processes right after running the top command at the time with the high power usage: grafik

A few seconds after running the top command the CPU usage drops down to something like this: grafik

I tried sending a picture via telegram with a bad mobile network signal. Telegram was not able to send the pictures. As soon as I activated Wifi telegram was able to send the pictures. Now my phone cooled down again. As you can see in the first picture the rapid discharging stopped right after sucessfully sending the picture.

Can someone confirm a connection between telegram unsuccesfully trying to send a picture and the massive battery drainage?

Flohack74 commented 3 years ago

Unfortunately we do not see the process names here. The display is simply too small. Teleports can utilize quite some CPU, but it is suspended in the background, so its not the thing that will drain your battery when you dont use it.

Free-Inside commented 3 years ago

When I do a "top" in the terminal and I lock the screen with the power button or I let the screen turn off automatically, when I wake up the phone 5 to 10 minutes later, the "top" command in the terminal continues to run instead of stopping automatically when the screen locks.

@Free-Inside you mean connected via ssh or adb?

Free-Inside commented 3 years ago

@Free-Inside you mean connected via ssh or adb?

no it is not connected to the PC, I tried several times and it does not do it every time

ghost commented 3 years ago

Well, I have some battery drain, too. Firing top via SSH shows cnss_diag as top most process (2-5% CPU) on a Oneplus 6T on devel channel. Second process is biometryd. The latter is spamming my system logs. Can I disable this process somehow as fingerprint isn't yet working anyway?

EDIT: I upgraded to 429 and it looks better so far.

SolAZDev commented 3 years ago

I happen to have a similar issue, I'm working on a port (so I apologize if Im doing this wrong) but the others with the same SoC seem to have the issue; where unity-system-compositor takes 100% of CPU.

Device: Samsung Galaxy S9+ (Other devices are Galaxy S9 and Note 9)

Flohack74 commented 3 years ago

Well u-s-c should only take CPU when the screen is active, is this the case during that CPU load?

SolAZDev commented 3 years ago

@Flohack74 in my case, it is in fact using cpu when the screen is on, and yes, its CPU Usage goes to 100%

Flohack74 commented 3 years ago

@SolAZDev and when you turn it off, it returns to normal? Still, it should not do 100% continuously, amybe spike a bit when needed.

ghost commented 3 years ago

I have to correct myself: the drain is still there. The processes cnss_diag and biometryd are slowly eating my battery (at a rate of 2% per hour if I don't touch the device). Is this device specific? Cnss_diag seems to be disabled in /android/vendor/etc/init/hw/init.qcom.rc, nevertheless it's still running. Can I somehow work around the drain?

Flohack74 commented 3 years ago

Yes thats purely device-specific. cnss_diag is a nasty thing, but I had something something seen to disable it. However, are you sure biometryd is also eating battery? It should be entirley dormant until you use your FP reader

SolAZDev commented 3 years ago

@Flohack74 Unfortunately, that is not the case. This is top running with the screen off image Edit: Should mention I'm running this via ssh

ghost commented 3 years ago

@Flohack74 Well, biometryd is crashing and respawning the whole time. I saw it in dmesg, other logs are disabled it seems. I helped myself by remounting / and /vendor rw and renaming biometryd and cnss_diag and now they aren't running anymore. I made a bunch of modifications yesterday evening and what helped the most was to disable network while the screen is off. Now it is <1% drain per hour.

Flohack74 commented 3 years ago

crashing biometryd: Do you have a fingerprint reader on your device?

ghost commented 3 years ago

Yes. Unfortunately it's an under-display fingerprint reader so I don't think it'll work soon.

Flohack74 commented 3 years ago

Can you obtain a logcat log from the Android container? We might see why the underlying API is crashing

ghost commented 3 years ago

How would I do that? Edit: will take a deeper look into it on the weekend (provided that you meant "adb logcat").

ghost commented 3 years ago

So I fired adb logcat and this is what I got: ~$ adb logcat /bin/bash: line 0: exec: logcat: not found

ghost commented 3 years ago

dmesg shows a ton of these: [ 0.000000] init: biometryd main process ended, respawning [ 0.000000] init: biometryd main process (9394) killed by ABRT signal [ 0.000000] init: biometryd main process ended, respawning [ 0.000000] init: biometryd main process (9413) killed by ABRT signal [ 0.000000] init: biometryd main process ended, respawning [ 0.000000] init: biometryd main process (9435) killed by ABRT signal [ 0.000000] init: biometryd main process ended, respawning [ 0.000000] init: biometryd main process (9470) killed by ABRT signal [ 0.000000] init: biometryd main process ended, respawning [ 0.000000] init: biometryd main process (9525) killed by ABRT signal [ 0.000000] init: biometryd main process ended, respawning [ 0.000000] init: biometryd main process (9634) killed by ABRT signal [ 0.000000] init: biometryd main process ended, respawning [ 0.000000] init: biometryd main process (9686) killed by ABRT signal [ 0.000000] init: biometryd main process ended, respawning

mfoucrier commented 3 years ago

Hello, I hope this can be useful... Since OTA18, when I'm on the move (on a train for example) the cell phone heats up much more when using 3G/4G than before, there has been a change in the 3G/4G stack. Yes, in airplane mode during the night the battery discharges a little faster than before too, but it is much more important during the day when using. Thank you for your work.

Does this remove IPv6 requests for the mobile network ? https://pad.ubports.com/p/nm-battery-experiment/timeslider#692

I've tried it on my OnePlus One for 2 weeks and I have no difference on battery consumption, but in the comments there is a person who says that it still receives an IPv6 even after the change. Does it really cut the IPv6 ? Is there anything we can do to turn off IPv6 and see if the problem is caused by that ?

donbubu commented 2 years ago

Hi, same problem on Fairphone 3+. Battery down within 27h, all off and cpu on 20%.

Edit: With connection "2g" and "2g/3g" it work over 90h , but with "2g/3g/4g" 27h and empty
