Interesting, yes. But is there such a difference in Xperia X and Xperia 10 memory that requires 3 times higher power consumption just for refreshing the DRAM? 3-4%/day of 2620 mAh battery in Xperia X, 10%/day in Xperia 10 of a little bigger 2870 mAh battery.
About the Wifi power drain.
According to some threads on xda, one can tune that by editing WCNSS_qcom_cfg.ini
I have bravely tried that, and I think disabling 5GHz might have improved power usage. It has also deprived me of internet usage on the balcony and in the garden.
So if you feel particularly daring today, it would be interesting to hear your results.
The setting to change is called BandCapability, the default is 0 which means either, 1 for 2.4GHz only, and 2 for 5GHz only.
The file to edit (have a backup!!) is /vendor/firmware/wlan/qca_cld/WCNSS_qcom_cfg.ini
DONâT play around with this file, do some research what the switches mean before changing anything.
Thereâs plenty of info out there, but as usual also plenty of bullshit advice.
That being said, i have successfully NOT bricked my device by twiddling:
hostArpOffload=0
gEnablePowerSaveOffload=5
gMCAddrListEnable=1
gEnableLpassSupport=0
but can not say whether they make any difference.
REboot required obviously after changing any of those.

Iâve got the feeling that battery live is significantly longer since the last update. Before the update, with 100% charge in the morning, the battery was empty in the evening even when phone was barely used the whole day. With new system update, in this case, charge level is still 85-90 % in the evening.
I investigated again my brotherâs X10.
Findings / Reverted back to stock Android 9;
current drain measured with AccuBattery app: about 140-250 mA consumption
Findings / After re-flashed to SFOS 4.4.0.68;
current drain measured with Battery Buddy: 4.1.1-1: about 330-400 mA consumption
(same figures as before the re-flashing)
All of the above: NCF off, BT off, WLAN on, Mobile data off, screen brightness Android: mid, SFOS: lowest
Now⌠there is something âfishyâ with Sailfishy here.
Can it be that cores are programmed wrong, not letting some of the cores go to rest/sleep mode?
Related to these topics possibly maybe:

It might be just a conspiracy theory, but feels like AOSP device configs have so many flaws and misconfigurations that Sony is either doing them on purpose or donât care about AOSP at all and doesnât give a **** about it to get it rightâŚ
Two thoughts:
- Hanlon's razor - Wikipedia
- For doing it on purpose, which costs money, there would need to be a business case for it (otherwise you wouldnât pay developers to do it). Which I doubt.

Yep. Like I said, just a conspiracy theory and a feeling⌠Thanks for the interesting Hanlonâs rule!
Xperia 10 uses interactive governor, which is not a bad choice. Newer devices moved to schedutil which is something widely used on linux, instead of Googleâs interactive , but I think the kernel is so old for X10 it probably is the best choice.
Could the AOSP sources by Sony be better? Sure. Are they made by really few developers and often differ from stock configuration? Also yes. But in the end Sony is the only manufacturer that does that. And even imperfect configuration, but done by the manufacturer is better than starting from scratch.
Also, I donât think those sources are that bad, they are decent.
As a user of X10 immediately from the moment it started being supported by SFOS till last months⌠it is a really shit device. Probably one of the worst phones I had in my life. Reading user reports from Android have similar problems to SFOS.
It seems other Sony devices work better, and I just moved to 10 III and minus a few bugs on SFOS side (cameras and sound) and after fixing that one bug in Sonyâs config, the experience is really great. Even the battery life is surprisingly good. Yesterday and today survived full day of a roadtrip with one charge.
Sorry but X10 is a flawed device, or maybe its config too, all Sonyâs are but this device in particular.
Iâm quite happy owner of X10III myself too.
Well, wasnât my original meaning to start ranting Sony here, big thumbs up that they have AOSP at all. Iâve never understood why Google allows AOSP to exist.
Anyhow, X10 with airplane mode on, only program on is Battery Buddy⌠330mA drain, doing practically nothing. I donât know where that current goesâŚ

Turn on the Battery-Safer mode, did you notice any changes?
Thanks, Iâll try this when I have the phone with me again
