Battery draining
-
Hi @giampy
Axolotl is probably the cause.
It requires to prevent suspension in order to get notifications working.
So it drains battery a lot faster.But it should have been the same before OTA16
-
@applee I had not this problem using axolotl before ota-16.

I bought my phone as a new device about a year ago, and flashed it to UT right after the Android update. So the battery is not preloaded.
On my Xperia (F5121) are only the official apps (12) installed and additionally the app Tagger.
(Where I have to take a photo first for the focus to work, and then load and process the image via gallery access, in the app. Works fine.)
I need the Xperia primarily as a cell phone, then I use the following apps: camara, calendar, calculator, weather, and occasionally the morph browser.
(As soon as the phone call via the car handsfree (bluetooth) works, there's money for the UBports community in the form of a donation).
So, the device is not used intensively, and that's why I notice the difference in battery consumption so clearly.
So it must have a connection with the update OTA-16, from my point of view.Translated with www.DeepL.com/Translator (free version)

Perhaps this can help, yesterday, in the afternoon, a pylon with the telephone antennas broke in the eastern part of the city where I live and therefore the phone does not work with the sim. From that moment the battery lasted longer, I was only connected in wifi.
-
@giampy Same issue with my xperia x, the battery drains faster now, after ota16.
-
@hsabun I wonder how you use your phones. I have my xperia X connected to wifi all day and I don't notice difference in battery. I usually charge once day and get around 18-24 hours per full charge.
-
@kugiigi If you used the phone with the sim card you would notice the pain. My Xperia X is for daily use on stable channel.
-
@giampy Yes, I have a sim card. It's my daily driver too. I don't use mobile data though, just wifi since I'm always at home these days I'm not a heavy user but I use from time to time for browsing, email, and telegram.
-
@kugiigi Apparently we have found the problem, the data connection with the sim card.
-
@giampy
Mobile data is known to drain the battery faster than WIFI (especially 4G) but that doesn't explain how OTA16 may have changed something.
The power consumption for the modem should not have changed... -
@applee said in Battery draining:

Is that specific to this particular phone or does it apply to all of them?
-
@cliffcoggin
This is the same on my phone, that's why i run most of time on 3G and only switch to 4G when i need more bandwich (more bandwich = more energy).
Wifi consume less because you are near source (most of time at home), so power needed is lower for same bandwich.This probably also has to do with frequencies used in each case.
-
@cliffcoggin
I would say the same as @Keneda
Of course depending on your hardware it could be mitigated, but in overall yes 4G uses more power than wifi. -
@kugiigi my Xperia x i don't use it as a daily driver, but it does get a sim and always on wifi. Prior to otp 16, I easily lasted for more than 48 hours, but now it's like 30-34 hours.

I also estimate the higher loss at about 30%.
It's not a big deal for me either, but in the blog <the release of Ubuntu Touch OTA-16> an improvement in battery life on the Xperia X was announced.Translated with www.DeepL.com/Translator (free version)

Maybe it's related to the latest kernel changes (Jan and Feb):

@c4pp4 This sounds like a clue, because I changed directly in the <stable channel> from OTA-15 to OTA-16. So without fluent update in the <developer channel>.
-
@mario-ch Look how many changes was made in a couple of days so I think fluent update wouldn't help.
-
@c4pp4 I meant that I noticed the difference, between 2 Dec 20 to 15 Mar 2021 better than if I had done the small updates week by week.
