Extensive battery drain on OPO

tomoqv commented 6 years ago

Device: Bacon
Channel: Devel
Build: r205

Steps to reproduce

Charge the phone
Watch the battery drain really fast

Expected behavoir

Battery drain of <5% per hour

Actual behavior

Battery drain of 7-10% per hour, with light use or idle

Logfiles and additional information

I have wifi, cellular (2G/3G/4G), bluetooth and location on, but the battery lasts shorter than it used to. I get about 11-12 hours until battery reaches critical level of <10%, sometimes shorter.

Flohack74 commented 6 years ago

Can you connect via adb, let "top" command execute, and then lock the device? See the processor load, is smth there using more than a few percent?

tomoqv commented 6 years ago

Hi @Flohack74 , sorry, I got tired of the battery drain and switched back to devel again after I posted this bug report. It seems battery performance is a lot better now, albeit not excellent - about 5% per hour. I'll let you know if I return to stable again. Thanks!

Maybe It will be a good idea to add the pidstat tool or sar tool to the next OTA this will allow people to find rogue processes the uses too much resources

NeoTheThird commented 6 years ago

I switched to my Oneplus One as a daily driver, and it usually gets me through the day. Since i didn't use it before OTA-2, i don't have anything to compare it to, though. Do you have apps running in the background?

tomoqv commented 6 years ago

Not that I am aware of. I thought that normally UT didn't run apps in the background. Here is what top looks like on my device a minute ago:

RomBuch commented 6 years ago

I also experience with normal use 15% akku drain with the N5 per hour (OTA2 stable).

The phone gets also quite warm (which is not the case with LineageOS) in the upper part, which indicates strong chip activity.

Example screenshot (30% in 2h): photo_2017-10-20_19-29-03

With LineageOS on the same device battery life was 24-36h (depending on usage, normal mode in Android, with the "energy safing mode" of Android it would last much longer), but regarding internet reports the LineageOS seems to be one of the most modest battery-usage ROMs available for the N5, so it seems to be "kind of maximum possible".

tomoqv commented 6 years ago

Title of this bug could maybe change from "extreme" to "extensive". Battery on my OPO usually does not last me through the day even with light use. I get about 12-14 hours, which averages at about 7% per hour drain.

Flohack74 commented 6 years ago

@tomoqv from your screenshot I see there is too much activity on upstart. Is this on stable 15.04?

tomoqv commented 6 years ago

Hi @Flohack74 , I am on Devel r205 now and can't even adb into my OPO now. I get the error: device offline, which is probably related to this #13. However, running top in terminal on the device itself shows similar data as above, i.e. a lot of upstart* stuff.

My battery now is at 44%, only 6+ hours since fully charged.

Now adb shell worked. Here is top:

BlueKenny commented 6 years ago

On Stable and Devel I habe no problem like this

PhoenixLandPirate commented 6 years ago

RC-proposed if I unplug my phone, and dont use it, by the end of the day its dead, but I dont know if thats my battery getting worse.

Dantali0n commented 6 years ago

Device: Bacon Channel: Devel Build: r128 (Ubuntu 16.04)

I experience the same heavy upstart & dbus cpu usage, the percentages seem to be much lower when I have the phone disconnect from usb / adb (around 5-10%).

Flohack74 commented 6 years ago

Guys we need to make sure to separate 15.04 and 16.04 properly. From this report I cannot tell whetever it appears on either of them or both.

Dantali0n commented 6 years ago

@Flohack74 Maybe its a good idea to add an 15.04 and 16.04 label so we can easily see to which Ubuntu versions the problem applies, Right now we are adding "[xenial]" to issue names I think that adding labels is an improvement over that.

tomoqv commented 6 years ago

My original bug report was for 15.04 and I must say battery stamina is still an issue on my OPO running OTA3 now. Very rarely will it last me through the day, even if I am not doing much calling or surfing.

Flohack74 commented 6 years ago

I have the OPO now as daily (15.04 r281), and I got still 30% after 24hrs, so it seems to be not easy to pinpoint the source of these issues.

tomoqv commented 6 years ago

I am still on OTA-3 and have these battery issues more or less every day. Today for instance, my OPO went from 100% to 55% in just 4.5 hours. Not much use, but all the radios on and bluetooth connected to my Pebble watch, but still...

Flohack74 commented 6 years ago

I got BT turmed off all the time, but use wifi and network daily. I am moving approx 1.5 - 2 hrs a day with public transport, the other time I am in wifi...

tomoqv commented 6 years ago

Battery performance is better today, 88% after 3 hours of very light use. But yesterday was horrible, I charged the phone to almost 100% around 4pm. At midnight battery died. Only a couple of sms in that 8 hour period. sftp://phablet@192.168.1.202/home/phablet/Pictures/Screenshots/screenshot20180211_004423162.png

Flohack74 commented 5 years ago

@tomoqv How is your battery ;)

tomoqv commented 5 years ago

@Flohack74 My OPO with xenial is idling for the moment and I am using my Pro 5 as the daily driver, so I can't really tell. Battery isn't great on the Pro 5 though, but I usually make it through the day with maybe 15-20% battery left.

jfrederickson commented 5 years ago

I recently started using a OPO with 16.04 and a brand new battery from iFixit. It does generally last me through the day, but battery drain during idle is pretty inconsistent. Sometimes it will drain much faster during which the phone will be warm to the touch.

I've looked at top output through ADB while this is happening though and nothing seems particularly off, so I'm not sure what's going on. I did notice at one point that my phone seemed to be disconnecting/reconnecting from wifi while this was happening; I don't know if that's causative though.

jfrederickson commented 5 years ago

...and I've just had wifi turned off entirely today and so far haven't felt the device heat up. So seems like it may be related.

RomBuch commented 5 years ago

I noticed that with my FP2 and UT the battery lasts much longer when the phone is without WIFI (and mobile data) in standby than with WIFI. I assume that maybe the Dekko app is also a reason. As far as I know it "wakes up" from time to time and checks whether there are new emails to show a notification (even when I have deactivated it for all my email accounts). This theory is confirmed because sometimes the Dekko icon "appears" at the unity launcher bar by itself (I assume when it found a new mail, but I don't open Dekko so often on the phone to really know it for sure).

Flaburgan commented 4 years ago

There is a big battery drain with data sharing, see https://github.com/ubports/ubuntu-touch/issues/42. Can everyone here confirm if they switched on data sharing at least briefly before the battery drain?

Flohack74 commented 4 years ago

What is data sharing? My OPO is doing very well on devel now, except of:

You have Dekko 2 installed and you are connected to either network or wifi, but cannot reach the internet. Dekko will go crazy trying to download mails and drain your battery
Sometimes on boot a process has a race condition and starts draining battery. This is not device-specific. Just reboot and its fine again. Except for that 2 cases I have my OPO as daily with an endurance of more than 1 day. Roughly 1.5 days of use.

Flohack74 commented 4 years ago

I also will close this issue now as it is very old, and we never got confirmations on that. Please try latest devel channel and compare your results. With OTA-12 this will come to all users.

Flaburgan commented 4 years ago

What is data sharing?

Sharing you 4G connection with a computer, turning your phone into a Wi-Fi hotspot. I don't know the english term for it.

Flohack74 commented 4 years ago

Ah well its called... hotspot :P - ok I would rather vote to open a separate item for this. Also, hotspot on OPO has other issues too so its not the best feature there.
