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.
I've had my T-Mobile HTC One for about two weeks now. Maybe 4-5 days ago it started to auto-dim the screen very quickly (after only a few seconds) and then a few seconds later it shuts it off, and I have to unlock it. This has gotten highly annoying. Under the display settings I have auto brightness off, and the auto sleep turned off as well (currently set to 15 seconds). Is this a software issues, or possibly faulty sensors?
I also have a couple other minor gripes with the hardware, namely the sleep/wake button is slightly depressed on the right side meaning it takes more effort if I push it on that side. I can push the left side no problem. This makes me nervous as I'm afraid this button may get stuck and it's the only way to turn the screen on/off since this phone lacks a "home" button like the GS3/4. I'm thinking more and more that I may need to just get a replacement, but I don't want a refurb. Any input would be appreciated.
hi...
well im pretty sad cause i dropped my galaxy s2 on the floor(not the 1st time)...this time when i switched it on all it shows is a white screen with crazy coloured lines.i waited a bit and i understood that it booted up.i pressed the power button and the display went off and heard the sound(i assigned it on pressing power button).then i again pressed the power button switching on the phone to its lockscreen and from my memory i pressed that jellybean locksreen buttton and slid my finger.anyways it unlocked and went to the homescreen.later i was able to switch off the phone too....everything works except the screen...
Is it just that my lcd is loose connected or is it damaged and would i need a replacement.
Sorry for the lengthy description if it bored you and my advance thanks to anyone who gives an answer and thanks to xda -for this forum.
Have a very close look at the screen under a not too bright light and see if you can notice any cracks. Sometimes you can barely see them.
If you can't see any, then if I were you I'd open it up and pray to God that it's just the screen connector that's come off slightly. It's a possibility.
Good luck..

My phone was working fine when I went to bed last night. I laid it on my night stand and this morning I noticed I couldn't get the screen to light up. The blue LED was blinking like I had messages. The Menu and Back buttons light up when I press them, and I can even hear when someone is calling me, but because the screen will not light up, I can't answer. The phone screen is in near perfect condition, not a scratch or crack on it and I also have a cheap protective screen over it.
Hoping it was just a glitch, I removed the battery and held the power button for about 45 seconds and powered it back on. Same thing, black screen during the entire boot process, no logos or anything. I also tried to boot it in safe mode with same results. There is only one time that the screen shows any signs of life and it only happens when I first power it on. In the top left corner for a split second, where the usual "Bootloader is unlocked" message appears, it displays a small rectangle of colored artifacts inside that small message area.
I assume the LCD went out, but I'm concerned it could also be related to the GPU or other hardware, and so don't want to spend a lot of money buying a LCD if it's something else. I can still connect it to the PC, so I'm hoping someone knows how I can test the hardware from the PC, or at least recommend something. Right now the phone is ringing and I have no idea who it is...this sucks!
