short battery life on OPO (Bacon) with OTA12

joolz

Hi all,

Since a short while (maybe unrelated, but it could very well be since OTA12) battery life seems much shorter than it used to be. Yesterday evening it was 55%, this morning almost empty. Wifi was off, phone wasn't used during the night. In the background a terminal and Sturm Reader were running. I don't know if ubports has a way to see the battery usage per app.

Could be that the battery is getting old, but I never noticed this before. The graphic show a steady decline during the night. This also happens whenever the phone isn't used. I haven't tested yet what happens when nothing is running, or how long it takes for a full battery to get empty. Does this look familiar, anyone has the same issue?

TIA,

Joolz.

I'm seeing short battery life too (also on Bacon) but

I'm new to this so I did not know what to expect
for now, I have WiFi always on, which I normally don't do.

But yes. One day is what I get and that's short, compared to the same device on LineageOS. There, I get three days or so.

I also notice shorter battery life of my OPO since OTA-12.
My subjective feeling is that the battery life is approx. 30% shorter now.

You could try moving to RC channel in System settings, updates, update settings and see if there is an improvement or even Dev. You can always move back again when you want.

Last night did another check: 23:00, I put the phone into airplane mode, no apps running except a terminal (with nothing running in it. It's just a habit to always have one at hand), battery percentage 38%. That night at 4:30 I got a low battery alarm signal, so that's 5.5 hours of doing nothing to use up about 1/3 of the battery.

Thanks @Lakotaubp. I will think about it, this is my main (and only) phone

I'm starting to think that the device simply has a battery that's not too great. I've ordered a fresh one and will report back.

Did you try switching network from 4G to 3G?
My phone last more than 48hrs iddle in 3G, no more than 24hrs iddle in 4G (MX4).

Hi,
also me have the same issue. Suddenly the phone overheats and the battery starts to drain faster. Before OTA-12 it rarely happened, now it happens very often.

@Keneda I did even better than that , I switched to airplane mode. Still whole lotta draining going on.

@Moem thanks for keeping us posted. This might rule out the hardware, although I don't think it's that. Seems that too many people are having this after the upgrade.

The same thing, really short battery life, after full charge with no Internet connection (WiFi or phone data), 2 voice calls less than 2min each, battery lasted 5 hours.

The problem of overconsumption is not related to OTA 12 (unless the problem has been amplified).

My experience with overconsumption (shortened...) and remedies :

The first indicator for OPO that will identify over-consumption of energy is for example when you switch it on and you find that it stays warm without using it because :
In the OPO if certain 'bad' (race) conditions are met the phone will start up badly. You can see that, :

the Bluetooth is switched on without having asked for it;
an absence of the wifi button seen by scrolling through the indicators menu;
the wifi button is ON (green) whereas it had been closed before switching off the phone...

What I advise: after an abnormal start of the phone, close everything that shouldn't be turned on, and restart the phone. Then re-check that everything seems OK. If necessary restart the phone again...

A phone that is switched on and not in use should not be hot. This is what happens to me with the OPO when it is working normally.

Hi @domubpkm,

I assume that when Bluetooth, Wifi etc. are onasked on, the indicators in the top of the screen will say they're on, is that correct?

The phone gets drained with everything off (airplane mode on, all indicators off) without getting warm. It might not be OTA12 related, but it's been happening since I upgraded.

Best,

Joolz.

@joolz As far as I'm concerned, I've never noticed any overconsumption on an OPO that didn't heat up more than normal for an unused phone.
so I can't enlighten you any further.
You can always open a new bug report here if your case is not already referenced:

My home WiFi seems to kill battery now, and its probably because of my IPv6 enabled internet. UT is not yet able to use this, so it prints an error and tries again. Leading to a device that wont sleep properly.

I can assure we did not change anything in those parts willingly, so its either a strange side effect of something unknown, or its just a thing of what happens in your WiFi. Because traffic will wake up the phone too, it needs to see if a packet belongs to it or not.

I'm seeing the same result on WiFi, too, and we too have IPv6 enabled internet. Now that I've switched the WiFi off, I'm getting an immensely better battery life. I don't know how long yet, but it looks like several days instead of 7 hours.

cliffcoggin

Moem, did you fit a new battery, and did it make much difference?

Moem

@cliffcoggin I didn't yet, it's on the slow boat. But this gives an impression of current battery life of my OpO on UT:

@Keneda Things got much better after changing to devolpers channel and build 51.
