I also saw faster battery drain on my Qtek 9000 after I installed TOMAL V8, so decided to check the actual current drain on the ROMs.

I used BatteryStatusExt.1.05.CAB to show the current in mA. I installed a ROM, reset, then installed the BatteryStatus app and set it to show power consumption as a Today plugin, with 1 second refresh. Then I waited for the backlight to turn off and the number (mA) to settle. I did the test with a 4Gb card inserted, with a SIM card in a GSM network. All other radio was off: BT, WLAN, IR. I used radio 1.10.3 (incorrectly labeled 1.09 on xda-dev's FTP!).

I didn't check standby figures - they can be seen by checking the number immediately after getting out of standby, as the BatteryStatus plugin takes a while to refresh

rdosti v11

140-160mA but in 3G mode !!! I couldn't get it to switch to GSM

TOMAL v8

~120mA

SHIVAM310

80-100mA

minhanhtran (ROM UNI G3 OS 5.2.20270) :

~128 mAh

So there is a difference! And that's with no additional apps but BatteryStatus, and with backlight off.

With 120mA, a 1600 mAh battery will drain to 0% in 1600mAh/120mAh = 13.3 hours, with 80mA it will go to 0% in 20 hours....

So with my oldish battery I will wait for rdosti to fix the "Notes not working" bug on his SHIVAM release :D

I think the difference could be noticed also with applications running, but it is harder to test.

With Ranju 7.7 and 3G my battery drains in just a few hours, never lasted a whole day. 13-odd hours - I should be so lucky. New battery, BTW.
[JASJAR, XDA Exec, MDA Pro ROM Development] cenarius:
Confused

I used batter status and show my drain is 642mA but my battery last for about a day (4-6) Hours of actual using.

Battery 1600 mA

Rom Tomal 8

Radio 1.15
[JASJAR, XDA Exec, MDA Pro ROM Development] blazzr:
I'd check the drain in mA and compare it with another ROM - SHIVAM310 for example (comparing a clean install of both ROMs + BatteryStatus + waiting for a few minutes with backlight off). Backup the entire system to a card first, of course.

Also, try a task manager to see if a process is keeping the CPU busy.
[JASJAR, XDA Exec, MDA Pro ROM Development] orb3000:
No with all versions

I´m using v7.6 and my battery, which is the original since aug 05, last me aprox. 24-30 hrs. Using wifi and surfing 1 h, gprs, 4 h, bluetooth 2 h and ocasionall music.

I must say that tested v.7.7 and noticed a faster drain of my battery and return to 7.6!

And is the perfect combination of stability (Performance) and speed

Congrats Tomal! so far the best ROM

Cheers to all
[JASJAR, XDA Exec, MDA Pro ROM Development] robsno:
I have tried several 6.1 ROMS all flashes done with battery at 100% and tested with several ROMS that was the same whichever battery I tried. For example tomals 7.7 would eat 18% of a 1600ma battery with it closed and idling overnight for 8 hours, this reduced to 14% if cache was disabled and the performance application options removed. This compares to the best battery consumption I got from Shivam 310 with office, SPB shell and voice command added that lost 3-4% in the 8 hours overnight. Needless to say I am sticking with the latter as it is more in line with the quoted life in the manual for all activities.
[JASJAR, XDA Exec, MDA Pro ROM Development] Jmp_3f8h:
I've installed BatteryStatusExt.1.05.CAB to test the current ROM I'm using (minhanhtran ) but I alway get 181mA, this is independent of the configuration e.g. GSM on or off, WiFi on or off and so on, so there is something I'm missing or what the hell is happening... :confused: any hints?

Marco.
[JASJAR, XDA Exec, MDA Pro ROM Development] cenarius:
Same here only 181 and sometime 642
[JASJAR, XDA Exec, MDA Pro ROM Development] rod555:
radio version for power consumption it's important
[JASJAR, XDA Exec, MDA Pro ROM Development] orb3000:
You make a very important point here

Would be good if some knowledge member of this forum adivise us which radio has better battery performance

Cheers
[JASJAR, XDA Exec, MDA Pro ROM Development] kotabunga:
pls use different radio version

anybody had tried different radio version for battery consumption ?:confused::confused:

I don't have the meters but, 1.09 last my battery longer than 1.11

:p:p
[JASJAR, XDA Exec, MDA Pro ROM Development] robsno:
I tried 1.04 1.09 1.15 and 1.18 with the T 7.7 rom and it didnt make any real difference to battery at all I also tried 1.09 and 1.15 with shivam 310 and both gave me 3 times the battery life of tomals rom with the same radio so i am of the opinion the key thing is the right rom flashed while the battery is at 100%
[JASJAR, XDA Exec, MDA Pro ROM Development] orb3000:
I´m using 1.08 and my battery (the original since 2005) lasts 24-30 hour

I can´t ask more of my old battery so I suppose this radio is a good one
[JASJAR, XDA Exec, MDA Pro ROM Development] fuoco:
I 've the Tomal's one. With a normal use my SPV M5000 is up for 3-4 days.

Every time a cooker distrubutes a new rom there is someone yelling for an abnormal power consumption. :rolleyes:

Real! :eek:

With new Rom the battery goes down very fast... cause the owner is testing everything, install all utilities & inutilities, and after 4-6 hours the battery line is down. After some days, with normal use, the Universal is going good again.:)
[JASJAR, XDA Exec, MDA Pro ROM Development] ftoz:
my consumation is about 180mA in batterystatusext105

I tried nev pdaviet 20273 rom and original 20270. It is nearly same. I have brightness on 2 degree and 128 MB ram. I think, ram is more depend on power consumation
[JASJAR, XDA Exec, MDA Pro ROM Development] sl9:
The reason Tomal's ROMs seem to use more battery power, is because they come with the CPU overclocking option enabled to 624Mhz by default, and some of the power saving options in Schaps advanced config are disabled.

If you reverse the above, they should be the same as the other ROMs in terms of battery consumption, if not even better.
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Hi All,

I also experience the touch screen issue on my Galaxy S20 FE.

I have created a short video on how to check and reproduce it: Galaxy S20FE touch screen issue - testing and reproducing

Please share your comments if you also experience it.
[Samsung Galaxy S20 FE Questions & Answers] maderos:
Did that experiment and i think my device is "ghost touch free".

Sent from my S20 FE 5G
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Yes, if you don't experience this, you unit is issue-free. I have also asked others to test, they have no issue at all.

This is why I think that *might* be a hardware/production issue.
[Samsung Galaxy S20 FE Questions & Answers] jtOttawa:
Yes, that's what it would seem to suggest - and it's discouraging, I was really hoping this was a software issue. Would the 120 Hz refresh be a factor in this? That is, do you get the same result at 60 Hz?
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Nothing. Either under charging or not, either 60Hz or 120Hz, no matter if Touch Sensitivity is set to low or high, it happens.

But as it doesn't happen for everyone with the same software, it tends to be a hardware issue or a production defect.
[Samsung Galaxy S20 FE Questions & Answers] jtOttawa:
Very interesting, and helpful - thank you.
[Samsung Galaxy S20 FE Questions & Answers] spacemanvt:
Tested mine with no issues but I had a bit of red tint on the screen as I have posted in another thread.
[Samsung Galaxy S20 FE Questions & Answers] SuperLGE:
I just checked mine and I have the same issue, would samsung rma for this?
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Thanks for the feedback. It seems not all users are having this issue. If you cannot reproduce the issue following the video instructions, then you are touch error-free. But then, it shows that it is not a general issue, but some manufacturing defect. For the red tint, I have seen your other post, I also have a barely visible greenish one, around where the camera is, and around the bottom 1/3 mark. But as it was stated, it is somewhat "normal".
[Samsung Galaxy S20 FE Questions & Answers] spacemanvt:
Do you notice a red tint when looking off angle at the screen?

I notice it somewhat when looking directly at the screen but very visible off screen, when using a white screen though.
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Good question. I spoke with Samsung Support and they wanted me to visit the Service Center. I told them that I will not spend that much time on it, this phone is too expensive for having this kind of support. I will just return it and ask for a refund, then wait 1-2 months if the problem is solved.

I was just thinking yesterday...

This phone has Gorilla Glass 3 on the display, which is a way different structure than current GG6 (or GG4). GG3 is much thicker and more acts like a glass (breaks easier). Since GG4, newer Gorilla Glasses are more flexible, thinner, and more durable, too.

What if Samsung has just put a thick glass on top of a modern digitizer (touch panel) which was designed for a different structure and much thinner glass layer, and this causes the touch problems?
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
I notice it under normal circumstances like browsing, while straight looking at it, when the page background is like pale yellow/orange. It is only a bit visible, but when you read text and scroll, it is disturbing that the greenish tint remains on the screen. But honestly, this is not that bad. On a white background, I don't even notice it.

When I look from a bottom angle and moving the phone's angle, the tint bars move as well.
[Samsung Galaxy S20 FE Questions & Answers] spacemanvt:
where are you located? I was thinking about doing this too for my red tint issue. but sounds like a lot of trouble. I would agree that you definitely need a new phone

---------- Post added at 01:06 PM ---------- Previous post was at 01:02 PM ----------

You mean are referring to the green tint correct? Are you saying that you have no reddish/pink tint at all on your phone?

I notice it very clearly when looking at it at angle or even normal position. And I can see it move when I move the phone to different positions.

the XDA review has the same issue actually (nothing on the touchscreen): https://www.xda-developers.com/samsung-galaxy-s20-fe-review/

"The viewing angles, though, are disappointing because the display still features visible angular color shifting to blue as well as a rainbow out interference effect at extreme angles. Newer Samsung OLED panels have eliminated the rainbow out interference effect, and also reduced off-axis color shifting by a significant amount. The Galaxy S20+’s viewing angles, for example, are much better because the color shifting is much lower. Strangely, even the cheaper Galaxy M51 (review) doesn’t feature the interference effect issue (that is likely caused by the polarizer)."
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
EU. I bought the phone in the official German Samsung webshop. If I would be out of the return period, I would of course take it to the Service Center even with the red tint, but this way, I will just return it.

True, I have no reddish tint, I have some greenish one :) When looking straight at the phone, it is around the opposite side of the camera, and about a thumb tall. But really, not that visible, I just see it because I know it is there :)

I read the quoted article. This can also easily happen because of Gorilla Glass 3, maybe it has different inner reflection that causes these bands.
[Samsung Galaxy S20 FE Questions & Answers] jaseman:
That sounds reasonable...however, what about all the phones using GG5, 6, or above that have a tempered glass screen protector on them, which would certainly make the glass atop the digitizer much thicker, and that do NOT have any touch issues? It seems to me that the thickness of the glass...up to a reasonable measure that I do not know what it may be...is not the issue here because my S20 FE does not have the touch issues. But mine does always turn on in my pocket. So it seems as if the proximity sensor is faulty. I wonder if this "bug" is somehow related to the touch issues. Though they appear to be different problems...they are related to how the screen works. Clearly something is wrong and I am not sure that any of it can be fixed with software. SMH
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
You are right, I also thought of it, but not only the thickness, but also the material structure can cause problems like transferring more static electricity to the digitizer that cause ghost touches. And the glass screen protector is on top of the screen which is far enough in distance from the digitizer. I can also imagine that combining this digitizer with GG3 would require less manufacturing tolerance than they used, and that causes just too much defective units. Just guessing...

But as you also stated, problems are mostly with the screen and touch panel. Ghost touches, incorrect finger recognition causing jerks, pocket wakeup, reddish/greenish tint on the screen. And +1: not all users have this problem.

If this would be a software-related issue, all models would be affected more or less. If some units are fine, some are wrong, with the exact same software, then it should be a hardware-related problem. Question: do they used different brand of digitizers for different units, or there is just a huge ratio of defective units coming out of the factory because they had to put as many units on sale as they could because Pixel 5 and iPhone 12 has arrived and they wanted to catch a lot of customers? Just guessing, again... :D
[Samsung Galaxy S20 FE Questions & Answers] spacemanvt:
So strange, every one of the phones I looked at in the store has these bands. Surprised yours does not.
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
If watching from bottom angle, I see the bands, but in straight view, I only see some greenish tint. It is not very disturbing for me. I mean, I have a LED TV, which has some of these typical IPS clouding effect on the screen edges. 99% of the time, it is not visible because the content is bright. But when watching a movie that has a night scene and there is no ambient light in the room, it is awful. But in general, I like the TV :)
[Samsung Galaxy S20 FE Questions & Answers] spacemanvt:
Interesting, thank you for the response. I see the red tint straight on and at angles too, so maybe we have a similar issue but a different color? :)

I also have a LG OLED, which can look quite bad in some very dark scenes because of banding.
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
That might be the case! Different color, but the same tint / band.
[Samsung Galaxy S20 FE Questions & Answers] xnappo:
Yes, apparently it has more to do with number of glasses of wine consumed than screen brightness. Sorry :P
[Samsung Galaxy S20 FE Questions & Answers] www1:
Same here.

After reset all return ok.

Ithink it's a software problem related to protection for not voluntary touch

FWIW, I recently bought a S20 FE unlocked from Amazon:

SM-G781U1/DS

ATL3 baseband

Dec 1 security update

HW rev 1.1

MFG Vietnam, Nov 13 2020

No screen protector (yet)

I haven't swapped my SIM over and made it my daily driver yet, but have been using/testing it for a few days with the visual tap and crosshairs turned on in dev ops. I haven't had any issues in regular use yet at all.

I do see the double dots as opposed to single when swiping quickly, but it hasn't seemed to effect use. IMO, it might just be how the digitizer polls, as I've read some weird things with high refresh rate displays previously (i.e. possibly intended behavior or cheaper parts). It is also ever so slightly more stuttery near the start of pinching to zoom than my Note9. It is very slightly more eager to merge two lines into one than the Note9, but I have to put my fingers are so close together, I wouldn't expect it to sense two lines. I've only notice these issues in the test app, not regular use.

All that said, I get pretty nitpicky, and I would've never noticed anything weird had I not read these threads. I went crazy on the touchscreen test app and in regular use trying to replicate all the different complaints I've heard, luckily to no avail. Maybe I've got one of the good units, or they changed something in HW 1.1 or the newest software that mitigates the issue. I'll put a screen protector on it since that will be my normal use case, and update if anything changes, but so far mine has been totally fine in regular usage.

(S20FE 5g [781B] Touchscreen Issue)

I bought it in May of this year and after the October update I realized that the touch screen was totally flawed, I never dropped it on the floor or was exposed in humid places. It's under Samsung's warranty but I have my doubts with the post-purchase service in my region, ratings on Google below 4, I would like to know if I could fix it myself with some custom rom or my only option is Samsung tech support ?
[Samsung Galaxy S20 FE Questions & Answers] xphyle1971:
Tried the touch test and my screen is VERY bad. Jaggy lines all over the place.
[Samsung Galaxy S20 FE Questions & Answers] xphyle1971:
Over on the Samsung forum they state that if you use the Samsung debloater app from the Play Store and disable the game optimization service, it fixes the touch screen issues. Here's the link.

I was able to replicate this issue actually. I tried the debloater app and it seems to be better.
[Samsung Galaxy S20 FE Questions & Answers] KageBeast:
If disabling those services really helps than it must definitely be a software issue which is good. I just got mine yesterday and although I've had the touch screen hiccup here or there it's only a minor issue for me. I see some people have it worse than others. I have the mint color.

[Samsung Galaxy S20 FE Questions & Answers] tofo17:
I got my S20 FE on Friday and noticed that games (multi-touch/two thumbs) would occasionally not respond. Ran the test per your video and have the crossing lines you got.

Have tried many of the proposed solutions (though not a full factory reset) and nothing fixes it, including the package disabler for the game optimization services, etc..

It seems like the problem falls into a few categories, either intermittent unresponsiveness with multi-touch or phantom crazy touches. I only get the first and I only notice it in games, pinch to zoom in things like Google maps is fine.

I've logged the error with Samsung through the member app. I've only got the September security patch, and given the issue is quite intermittent for me, I'll keep my fingers crossed this can be fixed in software.
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Cool, thanks! Show them the video and ask them what it is. I really hope the will respond somehow to this issue.
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
I have the October security patch, I installed it 2 hours after it appeared, but didn't solve the problem. Either it was a quick fix that didn't work, or they couldn't solve it with software. Which means, physical replace.
