1. This is not hardware related question, since I am using the same device for testing. It's one day with one ROM empty the battery before 4pm, the other day with DVHA it will finish the day with 40% left.

2. I am now on DVHA v22 - non-BS version. This is the first DVHA non-BS ROM. It's 6pm now and I have 40% left. This is still better than other ROMs, but worse than DVHA v21 which was BS (I am not sure this is related).

3. I am going to try PDACorner v24 big storage. This will be the first time I install BS version for ROM having also non-BS one (I hate big storage). I will try it on the first day it will be out of beta.

4. My device is JasJam, which is Herm100. Is there any differences in 3G module between different modifications? If so, it can explain a lot...

For the most part BS roms use slightly more power, and compressed roms even more so.

No, the different Hermes models are just different front facing camera's
[8525, TyTN, MDA Vario II, JasJam ROM Development] zocster:
yes I will have to agree with the BS stuff, as with non BS of pda corner and was on CRC's 11.2 I didn't experience any fast draining of what a BS of PCpro or any other roms for that matter.

i usually just view i dont post ...but i had to add in on this i only picked

pvdvh full v18

because it had the lowest idle %, and i regret every second of making this decision. ever since this rom has hijacked my phone, i have tried about 12 roms since ive gotten this phone, and none of them have underperformed like

v18

it had a "phone off" bug, where it wont let me turn the phone function on..i have to reset constantly, i have constant freezes, i can no longer use my usb connection to pc for some reason, and i seem to lose battery power at a rate of 1% every 2-3 minutes or so if the screen is lit. on the lowest setting :eek: . i believe my only option now since i cant pc connect, i have to get a card reader and load an sd autorun just to get this off of my dopod. i hope it hasnt done any perm damage :mad:
[8525, TyTN, MDA Vario II, JasJam ROM Development] veyka:
As with all roms, your mileage may differ, if that roms not so good for you, flash another.
[8525, TyTN, MDA Vario II, JasJam ROM Development] tko1:
good idea, thanks

Power consumption based on storage schema

If you run testing on different ROMs with a standard usage pattern (voice calls, SMS, Push...) using the same Radio set to 2G the difference will be the OS itself.

The part of the OS that makes a difference for battery drain is the way the storage is accessed, either directly (ROM/SDFlash) or from live RAM.

When the ROM is accessed it has to get powered and since it is slow the CPU has to be clocked longer not to mention that if data are compressed (RBSC)the CPU has to decompress the content before it's of any use. This may not be a huge difference but when you repeat this cycle half a million times it ads up to a lot more power drain - Same thing goes for the SD-Flash except these are rarely compressed.

The time-proven workaround is to set aside a region of fast RAM to shadow content from the power hungry non-volatile storage.;)

The bottom line of power drain is a trade off between Free-RAM size vs. DSK caching. The best of both world solution may be to run a cache resized automagically (HLM\System\StorageManager\FATFS\DataCache=0 and FATCache=0). The OS caches all it needs in RAM and automatically writes dirty pages to storage in the background or when more RAM is needed to run your programs.

Actually the above automatic cache schema is not the best solution for our phones. To further increase your battery life you need to hardset your cache size so WM does not have to keep resizing all its different caches non stop!

The big plus with hardset cache size is the RAM free space won't become as fragmented so WM will be less unstable.:D

Interesting Cache size settings are one of 512, 1024, 2048, 4096 in number of sectors... the RAM usage is only half that (2048 sectors fit in 1MB of RAM). Logically you want to keep a smaller FAT cache ratio for the Data it's pointing to. If it's too small you will get cache missed and data will get fetched from storage.:cool:

Now you can set your own preferences based on your needs and be your own chef: more free RAM for large programs Apps. or longer battery span.

Is that empowering to tweak your favorite ROM? :)
[8525, TyTN, MDA Vario II, JasJam ROM Development] ochakov:
After about a week with DVHA v22, I switched to PDACorner v25

It's 2:40pm now and my battery is empty.

Same device, same battery, same programs, same emails...

Everything is the same - the ROM is different. It was 40% battery left at the end of the day with DVHA, now it's empty in the middle of the day.

Any thoughts?

Arent you too smart not to cook ? :D
[8525, TyTN, MDA Vario II, JasJam ROM Development] sanfrenchysco:
Yep, I hear you mate! That's why I said:"If you run testing on different ROMs with a standard usage pattern (voice calls, SMS, Push...) using the same Radio set to 2G the difference will be the ROM OS image itself.

The part of the OS that makes the most difference for battery drain is the way the storage is accessed: either directly (ROM/SDFlash) or from live RAM."

Luckily I have some solutions ... but this will require manual reg. surgery on a per ROM basis until it gets integrated directly in the ROM builds (combination of PwrMgt fixes and ROM access avoidance for the most part).

Last weekend I spent half day poking around the UI while at the same time playing MP3 non-stop. After 6 hours I still had around 60% bat. I think I have the Reg tweaks for "long-life battery"
[8525, TyTN, MDA Vario II, JasJam ROM Development] galaxys:
Glad to have U on the Hermes forum! This sounds very interesting and Looking forward to your WM OS tweaks knowledge...
[8525, TyTN, MDA Vario II, JasJam ROM Development] sanfrenchysco:
You have a real good point :p but I don't know how to make my own sandwich...

If I am pleased with what is in the ROM, why try to cook my own when I don't know exactly how it's done?

Instead I fix the installed base ROM with my own performance tweaks. At this point I believe this is the most productive way for the user community instead of having one more cook competing for the best ROM combination of Apps.

I shall post my Long-life battery tweaks which by the way yields performance improvements through less ROM access.

On another note, the SDCard issues people are having may be caused by the SD internal wear-leveling logic relocating blocks thus scrambling cached FAT...

I will post on all the above once I can contribute sure fixes.

These days I am playing with cache size registry settings. Do you have the list of keys you are using for your tweaking?

I am already getting better results setting FAT cache to 8192 sectors. Now I finish the day with 20% battery left. Please post some other keys to play with. Thank you, mate!

Now testing just for a few minutes. Hdr doesn't work but that's not a suprise for me because most roms on this device have problem with hdr. Some animations are laggy but the speed itself is ok. I'll write more feedback after some longer testing.

Verify that I install your "rom" correctly since in the photos you can see that I am connected to the wifi, if your cell phone is blocked it may not recognize it, if your cell phone is not the model that I told you it may not work, it only works I tested and I am using in the model "j415f"

[Samsung Galaxy J4+ Guides, News, & Discussion] Didgeridoohan:
@soomin Since this is not your work I have moved the thread from the development forum (please note the development rules).

Also, since this isn't your work please make sure that you have permission to share it here on XDA and also make sure to give proper credits to the developer. Get back to me regarding this ASAP or I might have to take the thread down.
[Samsung Galaxy J4+ Guides, News, & Discussion] soomin:
I just read your supposed "retention or I don't know how to tell what you just did with the publication" but hey returning to the subject, to start nowhere does it say "it's my job" or does it say so? Another thing is that as well as in other sections of the page, different people publish apks, whether they are mods or originals .... so I said if I saw this ROM on YouTube and nobody says anything then I share it since nobody says anything, much less the publishes.

If I made a mistake then I apologize is what a gentleman does, I do not know who the creator of the rom is but if he is in the community I apologize publicly, just a detail the way you have commented the administrator and the other member called ADAM is not the correct one, no matter how much experience you have in the world of programming or any experience to make the custom of a ROM, it should be said in private since I have been a member of the community for a certain time only as a user (consumer) and not as a creator, the way they say it is as if I take advantage of the work of others and if you look at the publication nowhere does it say "MY WORK" but hey, it is your community you have the power to do whatever you want, no ?

I have already apologized publicly to the creator (if it is in the community) and to the people who saw the publication and those who will continue to see this publication until this problem is eliminated or solved.

[Samsung Galaxy J4+ Guides, News, & Discussion] Didgeridoohan:
Not quite sure what you are saying here... All I asked is if you have the permission of whomever made this ROM to post it here on XDA. And also to add credits to whomever made it.

It doesn't say anywhere that this is your work, no, but is doesn't say it isn't either. And the OP also doesn't have any kind of information about where the ROM comes from (again, credits). If you do not have the information to add credits, at least add where you found it and why you are sharing it here on XDA.

We love that people share stuff with each other on XDA, but we also like to see that recognition is given for the hard work that developers put into creating all the stuff that they share with us. If you want more details on XDA's stance on sharing and giving credit, take a look at the forum rules, section 12: https://xdaforums.com/t/xda-developers-forum-rules.4200559/

Hi Guys, could you please help me out? A few weeks ago my XZ3 started to act weird. It working perfectly, and after a random time, suddenly its losing both the wifi and mobile network connection (bluetooth is OK).

[Sony Xperia XZ3 Questions & Answers] J.M.Siyath:
issue may be in chipset so repairing is hard.

I gave it to seller then he sent me another xz3 phone.

now I don't have such issue.

I think it is a manufacturing issue, few phones has this same issue in all Xperia models like xz2,xz3, xperia 1....
[Sony Xperia XZ3 Questions & Answers] aizazkhan666:
i got it fixed from a local repair shop. The issue is caused due to some loose components on the motherboard. There are a bunch golden pins around the edges of the main board, the repair guy called them "signal boosters". i don't know what they're actually called. They're all connected to two main signal boosters right in the middle of the motherboard.
[Sony Xperia XZ3 Questions & Answers] aizazkhan666:
UPDATE: it's the plastic middle frame of the phone!! i finally figured it out.
[Sony Xperia XZ3 Questions & Answers] h.usmansultan:
I have the same issue.
[Sony Xperia XZ3 Questions & Answers] jimly_21:
What exactly did you do? replace the plastic middle frame? or repair it? how?
[Sony Xperia XZ3 Questions & Answers] aizazkhan666:
I'm sorry it wasn't the middle frame either. the issue came back after a couple of weeks, mostly when phone got hot under heavy use. i figured when i pushed hard on the side of the phone where sim card lies, the phone would lose signal for a sec or two and then come back to normal

I finally managed to fix my phone somehow it hasn't dropped signal even once in two months. i haven't been able to pinpoint what exact component is malfunctioning that's why I'm going to list every little thing i did..

it's definitely one of the metal contact points on the edges of the motherboard near the sim card tray that connect with the phones casing to boost the wifi and 4g signal. i put a small piece of medical tape on top of each contact point near the sim card tray to completely block them off. ( I've marked in the attaced pic exactly which contact points you have to block )

I've also removed the plastic dummy sim holder that sits just below sim card tray to fill the gap between metal sim holder and phones body. put a piece of paper medical tape there instead. put a small piece of paper in the top right corner of phone housing so that motherboard would stay a little above the housing when you screw it (see pic)

make sure motherboard screws aren't too tight

Don't worry it has little to no effect on phones signal reception, you're only blocking the sub antenna

[Sony Xperia XZ3 Questions & Answers] ferluna18:
So what you did at the end?

Any update on the matter?
[Sony Xperia XZ3 Questions & Answers] ferluna18:
I was able to partially solve my problem with my phone, I took out the black antenna frame and very carefully placed transparent scotch tape (because it´s thinner than medical tape) in all the contacts that are marked in red in the atached picture but now I´m thinking that I shouls have placed tape also on the places marked with green.

So what change I experienced on my phone with this method?

well the phone now has Network and wifi signal all the time and very ocassionaly it does lose the network and wifi signal for a second but when this happen the phone does not say that there is no sim card and does not freeze and restart, it just recovers signal by itself and I can continue using the phone.
[Sony Xperia XZ3 Questions & Answers] BreadWantBread:
Try open a airplane mode and then restart couple of times. And now you can use the wifi but when you turn the airplane mode off it just reboot several times. I've tried this and now i can use the phone.
[Sony Xperia XZ3 Questions & Answers] waayo69:
anyone still has this problem? i noticed that when i put pressure on the board just somewhere above the LED indicator both signals go out. issue is probably a short circuit?
[Sony Xperia XZ3 Questions & Answers] aizazkhan666:
For those still experiencing issues with their XZ3, I've included a picture detailing the specific points on the casing, near the top end of the motherboard, that need to be covered with tape. Additionally, place small pieces of paper or any material to elevate the motherboard slightly above the casing. The sub antennas are marked in the image. Avoid covering the points near the edge on the side next to the SIM card slot, as they are for wifi. You'll need to diagnose which contact point is causing the problem yourself

[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] XhibitA:
Good day folks,

I recently went to restart my Galaxy Tab today and it now no longer boots to anything but the NEXUS screen with an error: "Could not do normal boot. Invalid KERNAL LENGTH!".

Prior to rebooting it, the tablet was working just fine. I had originally flashed TWRP and Nexus_Stock_LP_T510XXS3ATB4-20200422 on to the tablet like a year ago or so. As of this morning, I cannot boot into the tablet and I cannot boot into TWRP either. I cannot figure out how to get Download mode to boot either. Everything I try returns to the same NEXUS screen.

ADB and Odin both cannot find the device since I cannot get past this initial boot error. It never even reaches the Samsung screen either.

I've seen this error on other devices and the key is getting into Download mode but for the life of me I cannot seem to do so at this point. Has anyone else run into this issue? Does anyone have any ideas on how to at least get into Download mode on this Tab to bypass this error?

Thanks ahead of time,
