I was just wandering what level most of you set your backlight to and how it affects battery life. Also, do you have auto-backlight set to 'on'?
Just trying to find a good balance between brightness and battery and so thought your experience would really help.
Thanks,
S.
Set to Auto here. No problems with battery life so haven't tried adjusting manually. I personally like the way it manages the back-light depending on ambient light
So I just got Tasker and I've been playing around with the light sensor and I've noticed something strange. If I set the display brightness is below 12% (12% is the lowest brightness setting in display settings), the light sensor stops working. Has anyone else noticed this?
It would be nice to be able to set the display brightness to 0% to save battery and still be able to use the light sensor. I'm running Perception 10.1 with glitterballs OC/UV kernel.
(I'm using Extended Controls to set and see the brightness %)

The lowest I could go is 8% using brightness level widget. If I am not wrong, 0% would be screen off. U could use "screen filter" app to further reduce brightness at night so it does not strain eyes. This lets u go as dark as u want, even upto literally where u cannot see anything on screen.
Hi,
How can i disable auto-battery save option that decreasing brightness when battery lower than %5-10.
I'm bored to check & uncheck auto brightness button.
Is there any solution ?
ROM: Overcome
Thank you.
Can anyone also confirm this please? If you go to settings > Display > Uncheck "Auto" brightness setting > set the slider all the way to 100%. Then, go to Settings again > Battery > Optimize battery usage. Let it analyze and then read the first row. Does it also say "Screen brightness set to 96%, set it to auto to save power?".
On my previous P10 LITE, it says "Screen brightness set to 100%, set it to auto to save power". It's either a bug or some weird setting I don't know of that can let you select full brightness.
Show's 96% for me too.
Weird, but makes no difference to anything!
I was thinking that the phone never actually goes to 100% brightness and it might make a difference in very bright places. We can't find out for sure if this phone has a locked brightness for battery saving purposes or if it's some sort of bug. I've emailed them but I don't have high hopes of receiving an answer.
Ok, so I received an answer from Huawei. They said that if I turn off the Auto check box and turn the slider all the way up, it is at maximum brightness. I am not sure if they understood what I meant but that wouldn't be the first time .
Also, on a side note, they mentioned that if I use apps with white background, the brightness changes automatically in order to improve battery life. I thought it only did this when there was bright light outside. The strange thing is that this in-app brightness fluctuation happens even if I uncheck the auto setting, but only when I use a custom brightness setting and not full brightness.
Such a strange feature, I guess the "disable" option nowadays means only what they want it to mean...

What is your current battery performance? Is your device affected with the fingerprint sensor bug that locks the CPU at highest frequency?

About 6-8 hours in moderate-high use, I guess. I don't think it is, how can i know?

Install a hardware monitor app like CPU-z or DevCheck. If you CPU frequency is not coming down from the highest value (for 4 small cores: 1843 MHz and for 4 big cores: 2208 MHz), you are most probably affected by the bug. You can disable fingerprint sensor to conserve battery in that case.

If you are talking about SOT, it's quite normal.
You can't really improve SOT.
It depends mainly on two things : Brightness and Kernel settings. Kernel you cant tamper with without rooting/unlockin your phone, so the best improvement can be achieved via auto brighness.
If you are losing too much battery while phone is idle/screen locked, here are some steps you can follow:
Limit background use of an application from Settings/Battery (Even google play services, notifications still come through)
Disable background data use of apps from Data Usage (Especially facebook/messenger ones, notifications still come through via GCM - use to your own likings though)
Clear Google Play Services cache, as it somehows causes battery drain
Disable location and google location tracking
Disable "Data always on" at developer settings. No point of keeping an active connection while on WiFi
Change network to 3G Only, if your 4G coverage sucks, so it drains all your battery

When i quit the app and come back, the frequencys are at the maximum value for a milisecond then goes to 1401MHz(CPU 0-3) and 1113MHz(CPU 4-7). So, I don't think I have that bug. What do you say?

Auto brightness? Really? I thought that was a battery killer. My brightness is in about 25% most of the time, so, I don't think that is the bigger problem, do you?
Well, thanks both of you guys for the help, and I will follow your instructions(but not the auto brightness one, I don't really like it), Reptant. I will try to remember and report the results at the end of the day.

Yes, that's right. Disable auto brightness, and keep the brightness at around 10%. It is more than sufficient in indoor conditions. Further, disable high accuracy location settings and set it to battery saving or off. You should also turn off WiFi and Bluetooth scanning in location settings.
I personally use a rather far reaching way of force stopping every social media and other news apps after using them (I have never observed any 'misbehavior' as they warn, but it saves a great deal of battery life.). As you can see in the screenshot the battery has lost 7% of charge in 2 hours and it still expects to last for 1 full day.

Min freq should be 633 MHz for the little cluster,it a bug with the 2nd October update, many users are affected,and so i!

Hello, any better result if phone is rooted ? Or any other solution? Thanks a lot.

The suggestions from Reptant above are still valid.
Other than that:
1. Greenify. Set non system apps to shallow hibernation. Try Amplify if you dare.
2. Disable ads. The image/video ads may not occupy a lot of your screen, but they use much more data than text. disabling those ads will reduce the amount of data that the modem needs to download, hence reduce battery consumption. this will have big impact if you surf the web a lot using phone.
3. Change CPU governor to powersave and/or disable some CPUs, reduce GPU max clock speed (you may not like this since it will make the phone laggy)
