The way that I understand power saving mode is that it saves juice by changing backlight based on what is on the screen. However in order to do this it.means cpu would be constantly used. So does power saving mode really save juice? Is the amount of battery saved by changing backlight more than the battery used by constant cpu usage?
That's a good question but I highly doubt that they would add the feature if they didn't test that it actually saved power. But, stranger things have happened.

I assume you aren't basing that statement on recent events of failed quality control on high-end phones
No, it does not.

And this is based on???
From what I have read, having power saving mode on is another process the cpu has to worry about therefore possibly causing more battery drain. Personally I have disabled power saving mode and auto brightness and have experienced a slight improvement in battery life. I use the slide on taskbar feature to adjust brightness manually.
I have both Power Saving Mode and Automatic Brightness on, 3G off, and I get over 40 hours in normal use! I hope that tells you these settings don't drain the battery and you shouldn't worry about having them turned on.
It is NOT putting an undue burden on the cpu, and small amounts of CPU usage have MUCH less effect than powering the screen.

I have to ask what is normal use for you? Cant imagine getting 40 hrs on any device besides a BBerry.

I find that the 'auto settings' takes away from a session - screen dimming and back again. Swipe to adjust brightness seems to work fine. As far as I'm concerned, the Vibrant is running normal when usage puts Screen at 83% or so.. After all, we bought it for the display to begin with

They released the phone without doing adaquate testing on the GPS.
HTC released the G2 without turning it upside down & seeing the hinge go a flyin.
Just because they threw a feature in doesn't mean that it's been tested.
We're the testers

He keeps is 3G off, thats what's saving the battery. That and he probably was sleeping for 16+ of those 40 hours.
Just an FYI, I have been running my phone on automatic brightness + power saving mode for the past few days as opposed to my usual lowest brightness + no power saving mode; and usually I would get inbetween 3.5-4 hours of screen time (depending on what I did) but now I am getting 4-4.5 hours (same usage). Obviously the automatic brightness does not improve battery life over lowest brightness all the time, so power saving mode must be doing something right -- something aside from just lowering screen brightness as needed.
That is a feature of 2.1 that is intended to help people with LED backlit screens by turning off LEDs in areas that are black. We have SAMOLEDS, which are lit by pixel, and we get battery battery life by using black themes. That is why Fusion 1.1 is nearly all black, and gets insane battery life.

Actually, that doesn't tell us anything. What is your battery life like with Power Saving and Auto Brightness off?
Here is how I have set up my radios to save power .
First u need llama and secure settings app from play store both are free apps
Basically there is 2 parts. Refer to the screenshots
1) HTC Power Saver. This mode is under power saver not to be co fused with deep sleep mode .
The Power saver terminates data connection after the screen goes off for 15 minutes . Now we want this to immediately go off instead of waiting 15 minutes .
So this is how I have set it up
Open llama create a new event condition screen off action run a local plugin - secure settings - custom Rom actions - HTC Modes . Make sure it is enabled , press save and back to llama , save llama event
2) extreme power saver mode .
This is new mode in sense 6 roms
However this only works when the battery reaches a low percentage or u have to manually turn it on. Now we want this to turn on by itself after xxx minutes . In this case I have set it to 40 minutes .
So i have created another thread as this
For this pls refer here for the steps :

Ok...just report in later
I have seen that Extreme power saver mode consumes more battery than normal mode. HTC have made a mess of extreme power saver mode in last update.

Hmm why do u say that.....
Which update and Rom are u talking about
Stock ROM Sense 6.0 4.4.2.
If I keep the phone in normal mode overnight battery drain is 0.6%/hour. Roughly it looses 4-5% overnight. I enabled extreme power saver mode couple of times before going to bed and both times I have seen my phone lost 10-11%.

Try LeanDroid, it does a great job of scheduling data to reduce battery usage.

I guess try app state disabled
I can't find an automatic power saving option on my S7 Edge on Nougat for when the battery drops below a certain persentage (eg. 15% or 5%).
All I can find is just a notification (for 30%, 40% and 50%) that prompts me to "tap there" to enable power saving which then opens another window with power saving options, I need to tap one, it takes a dozen seconds for it to change the power profile.. it's a drag.
So I'm wondering if there's anything automatic for power saving (like in all Android phones since lollipop) or maybe I somehow turned it off?
My phone was on 13% battery and still didn't switch to power saving (just the notification to tap there to turn it on).
Same here. I also can not find the automatic power save setting on Galaxy S7 / Nougat. How lame if Samsung took default Android feature out.
I see power saving mode on mine just fine.

Quite rude when people are trying to help.
So here's is a partial answer to my question: there is automatic power saving, it kicks in at 5% battery.
Anybody found an option to raise that 5% to 15% or 20%?
I checked everything battery and power saving related in settings and couldn't find it...
Device Maintenance> Battery.>App power monitor. There you can choose the apps you want to set power saving for and choose "Save Power".
It is not exactly the same as in vanilla Nougat, but if you want vanilla, Samsung is the wrong device.

No, that's not at all what I'm asking or looking for.
I know about this list, it is also present in vanila android, and it is completely useless...
I'm looking for an option to set the automatic power saving mode to kick in on higher battery percentage (20% or 25% or 30%), basically anything above 5% what the default is.

Right!? It's weird that auto-power saving only kicks in at 5% battery, but then again the battery is pretty impressive.
I'm getting used to manually turning on the power saving mode and tweaking the brightness if needed.
Yesterday I achieved 9 hours of screen on time, manually tweaking the phone as the battery drained.
Maybe they forgot the option with the 30/40/50% notification to also activate medium power saving.. a simple toggle is missing there :/
I hope they add it in a future update...

Yes the battery is pretty impressive and maybe they'll fix it like you say, hopefully!
I've not been one for power saving settings before but I like how this works, except for the one bug I've noticed is annoying me slightly.
When turning off the power saving and the resolution changes back from FHD to WQHD my keyboard (SwiftKey) size changes to really small so I have to adjust it each time; not sure if it's a bug or because the resolution is changing.

Yes, it looks like they have added a short way to reach the power saving setting screen, but avoid an automatic activation of the mode, rather then at 5%.
To activate it easily and using that fast activation, you have to wait until you get a notification for low battery, then click on the notification and select manually MID or MAX.
I just loved the old fashion automatic power saving....
I noticed the same right after updating. It is extremely annoying. It's frustrating when useful options which used to exist are removed. "Updating" is meant to make stuff better after all...
I liked the 2 power saving options before the update. One decreased performance a little & my screen didn't change. It was a little slower and not as bright. It was perfect and it's gone. The other was Ultra Power Saving. Apps were very limited. It was great when I was in a crunch & couldn't charge it right away. The new "improved" Power Saving is horrible & I hate it!
Updated my S7 to Nougat, couple days and regretting the decision more and more everyday. Yesterday I've noticed hey I'm at 10% and not in power saving mode like why? Oh we thought it be great idea to kick in power saving mode automatically only at 5%.....
There is suppose to be a Battery Saver option that lets you choose between 15% or 5% when to automatically kick in power saver mode. But apparently Samsung removed this option?
Yes, I also hate this change...
If anyone has a link to a petition or something please post it. I used to go powersaving at 50% and kept my phone topped off, I hate even seeing 2x%.
And I dont see an ultra saving mode, you basically flip the customization options each time? I understand the concept -- but we all like to have the phone at full-everything at least for the glorious first 10% after charge.
Then OK for the next 40%.
Then frugal mode kicks in. Being frugal all the time is just no fun.
S7 user here, the same thing happened with android 7.0 update. Really miss the auto power saving feature... I had set it to kick in at 20% and it was what I needed to have my battery last for a whole day. Now with Nugat update the battery doesn't hold for whole day anymore because of this, what a shame!
So there is no option to set it to say extreme power saving when battery drops below 10 % ?
Nope

My s10+ is with me since 2 or 3 weeks now
Now the adaptive power switches to medium power saving at just 68%
Is this correct?

It was at 25% exactly when the phone was new
Now it switches randomly
From couple of days it switches at around 50% then today it switched at 68%
It switches based on your usage, if it notices your usage is lazy in certain apps or during certain hours of the day then it will enable power saving, it's nothing you have to worry about and it gets better with time.
Where are you seeing this information? The only thing I'm noticing is that my screen resolution keeps changing from the highest to medium. I'm getting great battery life and I'm never in a pinch so why it keeps changing is annoying more than anything.
Edit: I found it and turned it to high performance. Then I hesitated but turned on adaptive too. I'll watch it for a couple of days and may turn it off.

You are seeing change in res and the phone switches to medium power saving mode and the default settings for this medium mode is FHD+ res
You need to change that then choose optimized again

Turn off adaptive power saving, that thing automatically changes your power mode depending on your usage. When you turn it off it won't change your power mode anymore. View attachment 4735427

Don't think so, I think it just monitors your usage and changes the power mode accordingly. Annoying this is that it changes the resolution too which it says that it won't do.

There's another adaptive power mode feature integrated in Android, they work well together.
If you set your Medium power saving resolution to the one you use by default then there's absolutely no reason for you to keep Adaptive power saving disabled, you won't feel any performance loss yourself, launching a game or app that is known to need the full performance will automatically switch back to Optimal, I recommend you keep it on.

Not at all just it affects overall smoothness of the ui
And it does not really conserve my battery as I don't use the full CPU power even in optimized or high performance modes

Well yeah, badly optimised apps are going to feel the lower frequencies, I personally don't use those two and everything else has been fine.
The 'adaptive power saving' mode is resulting in higher battery drain overnight (about 8-10%) compared to optimized mode (2-3%). I have tested this for a few nights and the results are the same. Disabling the adaptive power saving helps but this is not the solution as it defeats the very purpose of the feature. It's a similar issue with 'Medium Power Save' mode. Enabling this makes no difference to standby battery and overnight drain is anywhere between 6-10% compared to optimized mode. I dont have the screengrabs but I'm sure of this issue. Not sure if its just me or is this an Android 10 issue. (S10+ Exynos here).
