Did anyone notice that during the call, the screen isn't actually turned off, the backlight is still on, it just shows blank screen. You can see this if you are in a dark ambient because of the backlight bleed on the screen.
So, while you are talking, you will lose battery charge on call and on screen backlight. I don't think it is an economical way of spending battery juice.
So actually the screen is on the whole time during the call, you just can't see it because there is nothing showing on the screen...
Or is this just my device?
X10 2.1 nordic.
I noticed that, anyway during a call, it obviously drains the battery even though the screen switched off & the use of the Proximity sensor is to switch off the screen during a call to prevent the screen from touching than the economizing the battery
I noticed a big improvement of the battery with the 2.1 Update.
I've noticed it too, I think this would waste more battery? or is it the opposite?
Of course it uses more battery power. I can't rememeber if the same situation is in 1.6. Can anyone check?
It does use current, but i think its a minor amount. The reason why they leave it active but black for example, is that if you need to quickly access the dial pad you can do that, without waiting for a second or two for the screen to power on.
I recall back on 1.6 at times it felt like eternity that it would take to bring up the dial pad during calls. I'm not sure but check to see if the screen does in fact turn off completely after a certain duration, since that would be ok.
Nope, it doesn't turn off and I wouldn't say it's a minor amount of power, because the screen is one of the most power hungry components in our phones. So if you are in a call for say 30 mins just think how much battery that would suck out. And for me, for no good reason, when I'm on the phone I don't need the screen, that is why the proximity sensor exists, to turn the screen on and off
I understand, but you have to understand how the lcd works. Producing colours or tints cause the device to use more power. The brighter the colour the more power. Since white is the brightest tint or colour, whichever you prefer, black being the opposite would use the least amount of power for the screen being on. Unless this is a type of lcd matrix that uses most power with black I read about that before somewhere. But I highly doubt SE would do that. But considering its a concern of yours there might be an dialer app that negates this hmm.
At the Sony Ericssons products Blog there was a video about the new features at 2.1
It tells also that you could press the Power-Button to turn off the light during calls.
I´ve not testet this yet, maybe of you could test this. ;-)

It does not take a second or 2 for the screen to come back on. Just test it yourself by pressing the power button, it comes on within 1 second. On a side note, in the 1.6 days the screen would stay on completely and if you press the power button it hangs up. That was a terrible implementation.

Im on 2.1, cant check it anymore. It was rather sluggish for me on 1.6. The difference may be that I had pictures for all my contacts. I like it just fine.
Yes, you can turn the screen completely off by pressing power button, I've just tried. I don't understand why do I have to do it with my finger when I have proximity sensor that works just fine when it wakes up the screen from complete power off when I move it from my face. Seems like a bug to me.
LCD screen consumes the same amount of power no matter what image it is showing, black or white, so as far as I'm concerned showing black screen during a call does absolutely nothing for me, especially not for my battery. This is so trivial that I can't believe they missed it. Or maybe some SE engineer thought X10 has AMOLED screen so it doesn't consume power when it's displaying black...
Personally, I prefer the screen turn off compared to the screen lock in 1.6 as I had a hard time unlocking the screen lock when you need to use the dial pad when on the phone.
So when you are on the phone, the screen turns off and when you move your phone away from the ear, the screen turns on.

You are 100% correct, my mistake, lcds do use the same amount of power due to the backlight. I was just on the phone for 50 minutes and my battery went down by 5%, so i think its not bad at all. I was even on wcdma/gsm.
Drop SE an email to inquire on it maybe?
Well, maybe I'm exaggerating, but this kind of screen backlight beahaviour just isn't logical to me. You say you lost 5% on 50 min call? Hmm, that really seems low...
Where can I send inquiry to SE?
i have the same problem guys.....any solution yet?
working on a more accurate solution atm.
Posting here after MANY hours of searching various forums.
I have a rooted s-off mytouch 4g, with Dark Unicorn JellyBean installed (4.1.1, I hope I remember the names right).
A few weeks ago it got wet. Worked great for two days after and then seemed to die. Would only go to the white HBoot screen, buttons didn't respond. Left it turned off several days, trying once in a while, and just as I was about to go sell it for parts - magic! came back to life. after 24 hours of regular and rather heavy use, suddenly the screen faded out. Double pressing the power button brought it back up, but after 2 minutes it faded again, then after one minute, and gradually got to the point where I can wake it up but it fades within a second and goes black. The phone is still on, I can answer calls, and if I double press the power button, for a second I can see my home screen, can unlock it, if I press the volume up I hear the sound it makes when it hits max volume, touching the screen at the right places produces the vibration of touching keys, etc...
When I take the battery out and put it back in, it turns on and at the beginning the screen is bright and clear, with the mytouch screen looking good. Then it goes to the screen with the wheel turning around the unicorn, still bright and crisp, but after 10-15 seconds, still with the unicorn, the screen fades to black again, and as described above can only be brought up for fractions of a second.
I'll be sooooooooooooo grateful to whomever can help with this.
Thanks,
Roy
Bouncing, please help
Stuck here, would be very grateful I'f anyone could help
hey, everyone...
quick question to see if anyone has come across this particular issue.
i've been running dirty unicorns, toast kernel alex uses for that rom.
woke the phone up yesterday am after spending the night on the charger.
still plugged in, i checked the time.
pushed the power button again to put it back to sleep.
nothing...the screen stayed on, but frozen.
unplugged it from the charger, screen powered down.
haven't been able to get the screen back on.
strangely, the home, menu, back and search buttons do manage to light up, though.
oddly, enough...the phone still works normally.
i can guess as to what my security pattern is, hit the magnifying glass to power up google now and ask it questions.
i can also receive phone calls and swipe to take or hang up the call as usual.
once on the call, i can guess as to where the red bar is for hanging up.
phone works like normal...as long as i can guess as to where everything is.
also, when in lock screen mode i can side swipe to get to the camera and take pictures.
so, essentially, screen doesn't work...but, it still recognises and accepts touch input.
i just can't see a damn thing.
any idea?
took it to a sprint corp store and they changed the housing for me...for free.
changed the screen, top housing, etc.
they said it looks like it might be the board.
any ideas beyond that?
thanks again, everyone!
also, on a weird note...my battery is bulging in the middle.
i guess it's on the way out...with everything else.
I've had this phone for years and am having this issue too. Anyone have an idea?
yeah, it turns out that my screen's fried.
at least that's what the sprint tech told me.
pretty much everything works perfectly.
impeccably...i just can't see it.
i guess that's it for the phone unless i want to replace the screen.
they're rather inexpensive...depending on where you source it from.
Hey guys,
I am not sure if this is the right forum to ask, I am desperate and I need your help.
My navigation buttons started to push itself, so I disassembled my phone (gently of course)
I found out that the digitizer flat cable is torn like.. 3/4 of its width so that was probably the problem.
I ordered a new digitizer and it arrived yesterday, so I put everything together, started the phone and the LCD doesn't work.
When I start the phone it vibrates as usually, then the LCD screen turns on for couple of milliseconds so I can just barely see the HTC logo and then it turns black, the navigation buttons are lit and I've heard notifications after I let it run for 30 seconds.
What could be the problem? I checked multiple times if all the flat cables are plugged in correctly. It's weird that the LCD runs for couple of ms and then it turns black.
Thanks a lot for your answer,
Adam K.
How bright does the LCD get? It is possible the lighting element went bad.
It gets bright as usually, but just for half a second, then there's just black screen.
Hi!
My one month old S6 Edge fell down last week and the front glass broke. However I used the phone normally until today when I got the display replaced in a store. With an original out of the box display from Samsung. After that I noticed that the back and app key (the lowest touch buttons one the front) did not light up at all, although they did work. When I put the phone in the flip wallet cover it went dark and did not respond anymore. I could here it getting emails or phone calls but the screen kept black. I pushed Volume Down and Off buttons until it restarted, with normal screen (the touch buttons also lit up for a second) but after loading normally the screen went black again. If I took it out of the wallet cover it lit up, the two keys also lit up, but the keys did not work at all. Again forced restart. Without the wallet cover the phone starts normally and works except that the touch buttons stay black, but they work. The moment I insert it into the cover it goes black.
It must have something to do with the magnet sensor?!
I took it back to the store, the guy put back the brocken screen and it acted again the same. Then he ordered the USB Board (the part with the charging port) just in case he may have broken it himself but actually he doesn't know if that will help.
Do you have any idea??
Thanks!
