Camera brightness - HTC U Ultra Questions & Answers

Can we reduce the brightness without root or unlock bootloader?
It drains my battery like mad when I try to use for long filming

Are you using 4k as that will drain but you can download Lux lite

Nope not four k
I am wondering if we can crank down the brightness like in iPhones, so that the display doesn't eat so much battery when I am using the camera

Screen Filter

Maybe a useful post for some. I found this the other night, mainly because I was bored So if you use the app Screen Filter (which, by the way, is awesome for night time viewing in bed while the wife is asleep, you wont have to hear her say stop playing on your phone, because the screen is so bright!), but if you turn up screen filter all the way up to 100% brightness AND turn up your regular Android display setting up to 100%, you are basically getting your display level at 200%! And let me tell you...It is BRIGHT! I know this may be a useless post to most, but I found it to be actually very helpful in viewing my screen in direct sunlight, when the normal display brightness just wasn't enough.
Been using this app for months.

I am having problems enabling and disabling it consistently, but when I do enable it at 100% with my Android brightness at 100% I don't see any further brightness.
Also what is the advantage of this over the regular manual brightness?

I don't use it for brightness, I use it to dim the screen to a lower point that what you can do in the settings.
I've been using this app for a few months now. I love using it at night to watch a video in the dark, since the lowest setting for the brightness always seems to hurt my eyes in the dark.
That sounds unbelievable yet I believe it. I'd be concerned though that doing this might shorten the screen's life or damage it. As for that app it's been on my homescreen for a long time. Pretty essential.
Only problem is soft keys ofter are too bright for night veiwing

Automatic brightness better on or off ?

What's best for battery life, automatic brightness on ? Or set to a certain % ? Like at home if at 40%-50% that's good enough, but outside, or in bright area, hard to tell, much higher, or even auto.
Some phones do better or worse on auto brightness. Some phones can adjust quickly and actually do auto brightness very good, other phones I've had suck at adjusting the light level on auto.
What do you recommend ? And which is easier on battery life ?

Try lux. It can give you the best of both.

Personally, I never put my brightness on auto. I always put it at a certain percentage up to the point where I can see the icons on my phone and such. Putting it on auto will make the phone fluctuate between low and high brightness setting according to the lighting of the environment. When I'm home, I always set my brightness level at the very lowest. Also another thing I notice is that when I'm outside I need to turn up the lighting to about 10-20 percent and I good to go. When I'm indoors, the screen is quite bright and so I just turn it back down. (You get the point.)
I don't think there are phones that perform better or worse on auto-brightness. I don't even think it has any effect on performance. Anyways, to answer your question about battery life. If you can't see the phone while you're outdoors then you need to turn it up and thus it will use more power. Personally, I suggest that you set it at a fixed percentage rather than auto.
Was looking into this question myself. What I was able to turn up amounts to the following.
Setting the brightness manually or through the use of the auto brightness makes no difference if its the same percentage/ brightness setting.
The difference comes down to using auto brightness will cause the cpu execute to make the setting changed according to the polled data from the light sensor. The will cause minimal additional battery drain I suspect, but the exact number I haven't been able to identify. So this is the downside. The upside is that if the brightness settings are compatible for you, its very convenient.
As for the manual, you may gain a little due to the lower cpu use. More importantly, you can tune the brightness to what you want. If the auto setting for a certain outdoor environment is too high, if the manual setting is lower that the user prefers this could also save battery. Of course the opposite is also true. Same for indoors, etc... Being manual it requires you to change it, but using certain ROMs, quick setting tile or apps make this a lot quicker.
I'm personally running Xylon + Nova Prime + Brightness widget
Set the gesture swipe up, to execute the widget
Set 0,20,45,80,auto percent brightness in the widget
Swipe up to cycle through when indoor or out, home...

If you really need to conserve the battery I don't recommend having your screen brightness
at more than than 10%, most of the time I run at around 5%.
Asking others about their Auto Brightness experience is not very useful because a user
in Brazil will have a different result than a user in Norway.
If you charge your phone often and can read the screen at auto brightness just run it at that.
Otherwise you should always manually adjust your brightness for your own threshold of
readability.
A curious thing about LCD screens is that blacks and whites draw similar amount of power.
(As opposed to other technologies such as OLED). So ROMs with high contrast text that are
easier to read can actually help you save battery if you manually adjust brightness for readability.
I agree with using Lux, once setup and you have linked several light readings to screen brightness settings and set to dynamically adjust its great. The paid version allows you to dim the screen alot more then you can do normally and makes reading in bed very easy on your eyes.

Screen Brightness

Is everyone here satisfied with the screen brightness? It looks somewhat nice when the brightness is at 100% but then that drains the battery faster.
I have never used the 100% brightness - outside I'm not using the G Pad, inside I'm somewhere near 50-65% brightness, and for night reading 10-20% brightness. About battery draining, I haven't keeping an eye on it. When the battery goes near 30%, I automatically put in on the charger (I got one sexy thin 4m. USB cable here so I can keep using the tablet anywhere in my room)

50-65% for me seems somewhat dim, almost too dim to enjoy the HD screen. Are there any additional settings other than the main brightness setting? I do not have auto brightness turned on at all
Indoors i hardly ever raise brightness over 40% i have no complaints. In fact 100% brightness is damn near blinding.

Agreed. Brightness isn't an issue. The problem is that the gamma is too high resulting in darks being too dark.

So can we change the gamma in the kernel ?
yes, I find the ugly screen (very dark) with the brightness below 60%.
by 100% against beautiful. But ouch battery !!
No, you can change the gamma (and saturation, and brightness and stuff) in an app, someone mentioned it here on xda, but I can't remember it's name. Take a look around

I downloaded screen adjuster but it does not have any gamma or saturation settings. Only red, green, blue, brightness, and contrast. By the way, does anyone know how to take screenshots on this tablet?
hold Unlock + Volume down
I recommend using the app LUX. It does a terrific job of managing auto brightness. Way better than the built in logic. https://play.google.com/store/apps/details?id=com.vito.lux

I'm slightly ahead with this advice because I haven't even looked into rooting yet. But I can tell you if Franco kernel comes out for this baby that's what you want. It fixed the gamma settings and the color settings on my Nexus 4 completely. Made it like a brand new device with beautiful accurate colors and amazing battery life to boot. I will be keeping my eyes out for Franco kernel.

[GUIDE][CONDOR]Get the best battary life out of your device

Hi guys welcome to this thread and today I will tell you ways on how to get more battery life out of your device/1. don't constantly use you're device as this can lead to battery problems. Med-High use at max //2.If you're using a custom rom it can overheat the device so be warned, this can also lead to more battery problems, for example cyanogenmod. But the problems are fixed on that rom I believe/ /If you do these two things then you should be ok, good luck guys and try not to brick you're devices if you downgrade from lollipopto Kitkat/Hope this has helped and click the thanks button is this thread has helped you if you have had any issues on you're Moto E device.

This is your battery saving tip!!!
Ohh man we never knew that.
Great observation.
infinite battery life
Try using the infinate battery life script, if you are rooted. This can help increase the battery life by far. Hope this helps.
If you want more battery, root you're device and install a battery life script. If anyone wants to link I can give it to them. If this does not help and you done to root the device install a external battery life booster from the play store. Hope this helps if not pm me or reply. Good luck, if your device does not last at least a full day without charging turn down the brightness settings on the device as this will improve battery life. Another way would be to close any unwanted apps and 3g/wifi as this can drain battery usage. Hope this helps?
@ANDROmodderHD, I have just one "noobish" question: Why are you spamming? :'3
You are just asking us to just keep the phone on standby, turn off everything, even the apps we are using even those we need to be kept running and even turn off the internet, pull down the brightness to zero so that we can't see anything out under the sun. Then what do we do with the phone? Throw it away into the storeroom or sell it?
You could sell it if you like. I know where you are coming from but if you just turned up the brightness when you are using it then you can turn it down when you are not. This could help.

Don't you think the phone will be on standby with the display *off* when I am not using it? How will the brightness level matter then?
PS. You are damn interesting
I found out the battery lasts more then 24 hours when on a low to medium brightness setting. Even when you are not using it. Why don't you take a test to see if the battery would last more longer if it was on a higher or lower brightness setting when you are not using the phone. My battery life can last more than a day. So see for yourself.

I can't imagine how battery brightness can affect battery life when screen is off, I mean, no matter if you have brightness at maximum because screen is off.

C'mon man. We don't need to test because we know the phone is not stupid. What you are experiencing is called a "placebo" effect dude. Use your brains and don't act so noobish, no offense but this is getting irritating. I too made the battery last for 2 and half days when I did not use the phone at all because I was damn sick.
For improving battery life, try keeping the CPU clock to lowest (300MHz) when the phone is on standby. By default, the minimum freq. on LP is set to 787MHz unlike that of on KK which is 300Mhz. Just revert it back to 300MHz as min and set the governor to interactive. Or, ever heard of "deep sleep?" That's the best battery saving technique.

Exactly..!!
Stupidity ᕙ(⇀‸↼‶)ᕗ
Btw guys u can use GREENIFY app for saving battery and also xposed modules like Boot Manager.
Or flash a custom kernel which can sometimes make the battery last longer. This depends if you are already running cm or any other Rom with a custom kernel.
O.O
.... *slowly walks away*
Is this thread still going on??
Yes, if you want it to be on. Anyways this might be slightly of topic but is anyone running a custom rom. I know this may be off topic but has anyone got LP working on their device? Hope the update is good, what does everyone think about LP? Do you like it more than kitkat?

In this mod it increase the sensitivity of sensors and reduce power consumption used by screen or LED's in phone and use electrons present in battery according to an selinux algorithm which gives system ability of using less battery even in maximum brightness it is a screen based mod so it does not affect performance of phone hope you Satisfya with this explanation
