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.
Anyone experiencing random screen brightness?
Every once on a while when I turn the screen on I notice the screen is brighter (kind of washed out looking). If I put the screen to sleep and then turn it back on it goes back to normal. Don't know if it's a defect or what. Just wondering if anyone else had noticed something similar. (Smart Actions are not on so I don't think it's that)

I've had my Razr for about 16 days now. So far, this has happened once. I always use the phone with ambient light sensor off, and brightness set to lowest setting, but one night when I turned I the screen it looked like it was on the highest brightness setting, and the screen had weird colors. The reds had turned to purples, if I remember correctly. I turned the screen off then on, and that seemed to fix the washed out colors, but not the excessive brightness. At some point later that night, the brightness fixed itself without intervention.
yeah I get that too, been getting it probably once a day for the last week or so. I have mine on auto brightness and I can get it sitting in the same chair in the same light conditions a couple of minutes apart from no issue.
Switch on from lockscreen and the brightness is through the roof, hit power button to suspend and its fine when I go to open.
Yesterday I had it the other way, was really dark at first
Has anyone else had issues with their back light faulting? I've searched and have seen that other sprint evo lte users have had issues with screen flickering, but my problem seems to be more serious that that. when i wake up in the morning the screen is blank. thank god i have a custrom rom installed and can manually mess with the status bar slider to get the backlight to turn back on. It just needs to be tweaked here and there. the backlight seems to only like to work on full brightness, if not, it will flicker like crazy. if i press with more pressure on certain parts of the screen the backlight turns off completely until i remove my finger. I dont think its a proximity issue since it'll just flicker sitting on a desk. Do I need to replace the screen? is this worth it? i havent dropped to phone or anything for this to default. I can upload a video later. gonna use my OG evo for that which is still kicken by the way
I realize this thread is incredibly old, but did you ever find a solution to the flickering problem? I just started seeing the exact same behavior, including the screen going dark when putting pressure on certain areas of the screen.
Thanks!
I have a PJ75100 doing this, but the screen does not function at all. I get the orange/green light while charging, and if I power it on it acts as if it's doing it's regular startup, but nothing shows on screen.
I did update the stock firmware with the latest release ruu, but still no screen.
I'd really like to get this one going as it's not the normal Jewel, it's the white and silver one, and my girlfriend wants it to replace her iPhone 5c.

Just received my Gear S and love it so far. I have one small issue though. When I turn my wrist to turn on the screen, it comes on yet is a little dim and i have to swipe or touch the screen before it becomes responsive or is fully lit up. Is this normal behavior to save battery?

Figured it out. If you set it to wake to last screen it will wake up to full brightness.
It is quite bright, especially at night. Is there a way to control its brightness?
My Xperia 1 III is rooted if that's needed.
Thank you.
I just put the phone screen facing down
This is a technical forum and expects technical response to the asked question.
That's weird. My xqbc62-v notification LED is dim and has a narrow viewing angle. I can only see it at night.
I think there are multiple hardware revisions of this phone. My first phone was purple and crashed constantly. I returned it and bought a new one later. It's purple, but so dark that it looks back except under direct sun.
I see what you mean now. The BC62 notification LED used to track ambient light and it was always relatively dim. Starting with the Android 12 update, it's max brightness all the time. It's annoying at night.
Yep I can confirm that the LED is much brighter after A12 update. I charge the phone wirelessly at night beside my bed so putting it face-down is not an option. ;-)
What I have found to work is completely unscientific but works every time for me. I use a cable so not sure if it will do the same for wireless. After I plug it in I too notice that the LED is too bright. So I wait a minute or more and unlock the phone with my fingerprint (while the charging cable is still plugged in) and then double tap the screen to relock the phone. I use Nova Prime as my launcher which allows me to double tap to lock. Usually doing this makes the LED dim down considerably. Sometimes I have to do it 2 or 3 times but it always ends up working. YMMV
Anyone knowing a 2ay to disable the LED while charging? Maybe via adb command?
