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.
Got the E3D on launch date and I love every single thing about it. The only thing im waiting for now is root, but thats another thread & story.(BUMP, ROOTZ, I GOTZ THAT) Right before your screen gets ready to shut off, all the soft keys at the bottom would flicker letting you know that the timeout is about 3 to five seconds to hitting zero and shutting off completly. Tapping the screen right after the first flicker will cause the soft keys to flicker again letting you know you restarted the screen timeout to whatever setting you have it set to (15 secs, 30 secs, etc). I noticed this last night while reading a long article about a docter talking about 3D and the affects on the human eye. Dont worry, no damage from long term use, but reading long stories in the dark is where i see it coming in handy the most.
During a phone call, my proximity sensor doesnt seem to be sensitive enough. The screen turns off when I hold it to my ear, but when I pull away to look at the screen and interact with it, the screen either doesnt turn on or it will flash on and off again repeatedly. It seems that the phone cant detect that it is not near my head any more and should turn the screen back on.
Generally it wouldnt be a big deal since the screen does turn off when its held near my head, but when I needed to use the dial pad for a menu prompt it got really frustrating when trying to press in numbers with the screen switching on and off. (I just called Verizon CS recently and navigating through the menu was a pain with this screen going on and off).
I'm coming from the Samsung Charge which was very responsive: when you pulled the phone away from your head, the screen instantly turns on for you to press in keys or hang up. With the Rezound, it doesnt turn on most of the time and I have to press the power button (which will turn it on and then automatically off again...). The problem is alleviated if I'm in a very bright place (direct sunlight) so my guess is that the proximity sensor may not be sensitive enough to detect the difference between darkness and low lighting conditions. I'm sitting in a room with a 26W CFL lamp (so not too dark) and the Rezound has trouble turning the screen back on during a call when I pull the phone away from my ear.
Was wondering if anyone else exhibit this condition or if its just specific to my device (in which case I'll have to give Verizon a ring to get another replacement)?
I'm having the opposite problem. It unlocks itself a lot up against my head. My thunderbolt did this so bad I got a replacement thinking it was a defective proximity sensor. But it wasn't and I got in the habit of manually locking the screen on calls. But now my rezound does it but not as bad. I think htc sucks with proximity sensors cuz auto brightness is never programmed properly. It doesn't go dark enough compared to Samsung and motorola phones with auto brightness on. It only has about 3 brightness levels like in the HTC brightness widget, whereas stock Android has 5.

I'm having the same problem. The sensor would force the phone screen off as soon as I make a phone call. The verizon rep had me hard-reset while I was on the phone with her. The same symptom arises after the hard reset and the phone is brand-new.
I had to reset to get her to send me another rezound replacement.
On this replacement, however, I'm having the same issue again. My gf's rezound doesn't seem to have the issue.
I'm having a second replacement sent now. This is pretty annoying.
The interesting thing is the issue comes and goes. One day the sensor wouldn't respond, and other days it works fine. Although I would say that the issue deteriorates over time and never improves.
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
Hi everyone,
I'm sure this question has been asked by many users, but for some reason none of the ones I read seem to match the problems with my S6 Edge.
The other day I was playing music Youtube on my 3 year old S6 edge (for like 30min) and I forgot that autoplay was off, so the screen turned off, within 10 seconds of it doing so, I pressed the home button to 'wake it up again', but the screen won't turn on. the phone reboots once by itself but the screen remains off, and I know the phone's on because of the blinking LED light of messages, or the red when it is charging. The backlight lights up too, and it seems the screen's touch system works, as I am able to turn it off. I wait for a couple of minutes before hard resetting it (Volume down+Power key) and the screen lights up again and it's all good.
However, I have noticed this happening way too many times lately and noticed a bit of a trend. It usually happens when I use any app (except the music app) for 30 minutes or more, and if I manage to keep the screen awake, it works perfectly fine. The problem begins when the screen sleeps due to inactivity, or is voluntarily turned off. It also heats up quite a bit.
I am on the latest firmware, and have already formatted the phone once and tried, yet the problem persists. With that I suppose we can rule out that the problem is due to any third party app, or due to not updating the firmware. I also replaced the motherboard last year at a reputable phone repair shop, so I think it's a safe bet to say that's not the issue, but I am not 100% sure (the problems began 6 months after I 'unrooted' the phone, after replacing the motherboard).
As I kept going with it, it kept getting worse until eventually, now the phone is in a constant state of 'screen off but phone on', where it charges, plays music, can receive calls and messages, but cannot turn on the screen. I kept trying at 15 minute intervals to no avail, even though the phone is at room temperature.
Before I go blow a couple more 100 bucks on fixing this, I would like to hear all of your opinions on what the problem might be (and hopefully the solution).
Thanks in advance.
i have the same problem but i have the galaxy s7 edge. often i can unlock my phone but my screen will stay black. no aod or backlight but the vibration from unlocking with fingerprint is there and the sounds of opening an app are also there...
