XA2 Ultra [h4233][3.0.2] battery runs flat over night

The drain caused by WLAN (while device mostly idling) has been measured to be about 3-4% (battery capacity) per hour. So a full battery should last for about 25-30 hours.

wifi is not the only reason! turn wifi off and the battery will still drop significantly.With such battery it should last for at least 2 days with average usage.I cant understand why on android, batteries last much longer than with sailfish installed.Im still supporting Jolla but im surprised of how much they're disappointing in return

In addition to WiFi drain, 4G also drains the battery significantly faster. I mainly use 3G and WiFi only when needed. I have 50-40% battery left by the end of the day (roughly 6:30 to 22:30). And I have Android support on all the time.

Nope, Wi-fi nor 4g can be the reason for the drain. I have disconnected both and still lose at least 20% over night (which means within about 8 hours). The new battery saving mode also does not seem to work as relieable as the one from one guy whose name i forgot on OpenRepos. That one redueced the drain, at least on my Xperia Xa2 Dual-SIM to under 10% in the same time.

@Robberey, if you are referring to this: https://openrepos.net/content/coderus/jolla-powersave-settings then it does exactly the same as the native powersaving settings (at least if I understood the code correctly: https://github.com/CODeRUS/jolla-settings-powersave). At least I don't think that there's multiple instances of powersaving options in SFOS.

20% during 8 hours is 2,5%/hour, so it's not that bad for SFOS, regarding that the power consumption is (what I've understood) generally higher than when using Android on the same phone model. I get roughly 4-5%/hour with 4G/Wi-Fi (when used) on. So there must be something that's draining your battery significantly.

That somehow does not explain why the battery drain is so excessive during night time. With 3.0.1 I used to go to work at 7am with around 70-80% charge and get back home about 5pm including commute and still have around 30% left. Then i charge it back up to 90-95% and leave it over night. That has not changed at all with the exception that the battery no goes dead over night in just a few hours which it did not do before the update. oh yes, i d use Aliendalvik but there's just a hand full of Apps, the most power guzzling being Whatsapp. All other android apps i use do not have or need background services.

I tested it for one day with aliendalvik turned off and it is unchanged. The battery on the android in idle condition (standby) without the sim card after 24 hours took about 2% and the sailfish (also standby) without a sim card and on Airplane mode 7-8%.

That's a good point, i will try and change that. Even though i did not change anything prior to updating.

on my case i couldn't see directly that situation was involved. but i noticed that it happened mostly if i had it on working. Then tried, couples of days without situation. and no problem. then i make my observation with situation on working and noticed that happened a drain with 2 situations in parallel with same setting-point with different values between each situations.
Then i realized, that currently the app don't detect some "parameter-settings conflicts" and secure the phone from this.
That's point that is relative new for me (since less a week), i still don't communicate it to the app-devs. But i have it on the scope... ;-)
Thought that may eventually a point for you... maybe not....
Please give feedback from your future observation.

I did a couple of things, first off, i changed all Situations rules so they would not conflict each other. Then i installed the new vendor binary 17B. The issues appear to be gone now and i even improved battery consuption during daytime. I'm still losing around 15-20% over night, which i consider quite a bit much but it's way better than before.

hmmm interesting things.... i ask me if it's possible later that the sfos update could apply a binary upgrade. (i'm too lazy to flash my device again and apply settings and backup back, that's my main usage phone).

After installing the vendor binary 17B Advanced camera does not work anymore. But i never experienced excessive battery drain by that app before.
