[Q] Custom Rom Thermal Management - Xperia Z Q&A, Help & Troubleshooting

Hi!
I noticed that (at least the) custom roms I tried on my XZ make the device run way hotter than the stock rom.
Is there a rom out there, that already integrated the sony thermal manager or can someone recommend a rom that has good thermal management?
I am currently running Beanstalk 4.4.
Best regards.

In simple terms stock based roms will use the Sony skin and many of Sony's apps - typically the developer will have tweaked the build to improve performance or used the most recent version of Sony apps from higher end devices (the Z1 for example). They may also add some extra features - (using the volume buttons to skip music tracks/advanced reboot menu).
Custom Roms won't have any of the Sony features and generally will be closer to unskinned AOSP (Android Open Source Project) in appearance. They will mostly have some unquie features and be more options for customisation than a stock based ROM. Developers can also release higher versions of Android than Sony, allowing the user to experience Kit Kat long before Sony release a build. They tend to perform better than stock builds because they are less bloated. Sony has significant facebook integration within it's builds for example, similarly whilst it's possible to ignore it, there is a lot of secondary marketing within a Sony build trying to get you to use their music/video/games services. Most of these apps are heavy, slowing down the device. The SP copes fine, but their are definitely smoother custom roms out there.
Ok thanks !

Which is the current best stock-based rom for an update

Hi,
I've been on 6.0.1 with kernel 3.10.84-OM5Z (rooted) for about a year now, but would like to update to the current best rom for fully functioning camera (with DRM patch), battery life and heat.
Have been watching and waiting regarding Nougat. What's the opinion? Which is the best stock-based rom/patched kernel combo to go for at the moment?
BR.

Custom Rom with best battery life

Hello guys!
It's simply impossible for anyone to try out all ROMs and find the best one for his needs. I'm not different. I just wanna know which ROM is best in terms of battery life for Redmi 4x?

For me its rr Luis build, and anonymous 3.5 kernel, give bestest battery backup, but but but anonymous 3.5 kernel didn't support nougat roms and after flashing that kernel my video play back got broken, so I flash all the kernel for nougat and all have almost same battery backup, clarity, Gabriel and anonymous v2 kernel etc, but if gaming is not your priority then I can give you best setting for anonymous v2, because only this kernel currently have cpu underclock with nougat support,
Mokee rom has best battery backup

Custom Kernel to increase battery life with original or GPE firmware?

Hello,
I have 2 HTC M7 with slim rom 7.1.2. build.2.0 and GAPPS pico. One of them is S-OFF with GPE firmware (6.04.1700.19). Clean install via TWRP, no further apps installed, so far. Both phones lose about 1.5%/h battery in stand-by - thus more than twofold compared to stock firmware+rom, before.
Can anyone tell me, what are the reasons for this higher battery consumption? Forums on custom roms mostly give information that battery consumption will be improved with custom rom.
I think of installing a custom kernel to improve battery life. Where can I find a compatible kernel to my custom rom and different firmwares? Or would it be sufficient to install a kernel tweaking tool (eg. kernel toolkit) to adjust settings for the current kernel? In Slim Rom, kernel information is 3.4.113-g9776217([email protected]) (gcc version 4.9 20150123) prerelease).
Thank you very much.
There is only one custom kernel for N Roms and this one doesnt have any improvment for battery or kernel tweaks, there is no way to extend the battery life except for dont use gapps. You will get the best battery life with gpe rom and elementalx kernel, but this is android 5.1, but this is the only way to underclock the cpu/gpu with all adroid versions higher like 6.x undervolting allways caused system instability. If you want to have a bettter battery life with android 6.x or higher the only way is to use nanomod microg (or the new name of this magisk module "nanodroid") instead of gapps. It will replace everything what google services do for you with opensource programms, you will be able to use your google account as usuall and being able to use the play store but without the high battery drain gapps are causing. If you want to know more about this you can read everything here https://forum.xda-developers.com/htc-one/help/tips-standby-time-t3661814
Thank you, I will try it. As I have seen this should still allow for using paid apps from play store if needed.
Though I don't understand why battery consumption with custom rom nougat is that higher than with stock rom lollipop. I also tried clean installing custom rom without any GAPPS, but battery drain in standby and with flight mode was still considerably higher (0.9%/h) than in stock rom incl. Google services and no flight mode (0.5%/h)?
Hm, now I have
- 1 M7 S-off, GPE firmware, Slim rom 7.1.2 build 2.0 + microG
- 1 M7 S-on, HTC firmware, Slim rom 7.1.2 build 2.0 + Gapps pico,
- 1 M7 S-on, HTC firmware, HTC stock rom.
So far, no further apps running, GPS, NFC and bluetooth deactivated. Hourly battery drain in stand-by is almost identical on phones with slim rom (1.5% per hour) - and more than twofold compared to stock rom (0.6% per hour). Since I have tried several custom roms before, I noticed that other Android M+N roms (lineage, AICP, xenon, tesla) all have battery drain comparable to slim rom.
Seems to me that there is no way to get low standby battery consumption with a custom rom Android M/N. Within a 16 hour day I loose about 15 percent battery more than with stock rom Android L only due to standby. Am I the only one with this issue (or the only one interested in this)?

If you have identical battery drain on both devices with slim rom (one with gapps one with microG) there is definitivly something wrong on your side. Every user i have ever read from using microG said the same about better battery (about 10% more at the end of a day compared to same rom with gapps). And for me it was the same, with aicp and gapps i had only 15% at the end of a day, with aicp and microG i had about 25% left.

best custom ROM

Hi guys,
I am currently using miui9(android7) custom ROM on my z2pro, and looking for a good ROM to switch to because of latest software/security features.
My main criteria for an ideal ROM is the one with full hardware support and comparable battery life as in Nougat ROMs.
so I would be thankful if you share your experience regarding above criteria of latest ROMS.
