Hello
Back in the days when I had an s3. I remember that the power saving mode had a significant effect on the battery life as well as performance.
Can anyone explain how the battery saving helps in gs4. I notice no performance difference here. Are the a15 cores still getting used when the mode is turned on?
Also, can anyone report better battery life with powersaver turned on vs off on i9500?
Thank You.

Does anyone know what does the power saving mode really do? Does it really save the battery? Feedback is most welcome. +)

i guess the most noticeable feature is lowering of brightness when battery level is at 15/10 % and below.
and the battery notice when below 15%?
turning off display ?
Has anyone done back to back tests of using Power Saving mode through a whole charge vs. not?
I have done this, I was able to increase my battery life by more than 1 hour. I did have to disable the background screen setting however, it didn't work great with the stock email app, and my emails appeared blank, because it would change the text to white, but not change the background to black.
I'm in the process of doing this
it worked reasonably well, probably about 20% or so improvement. I then uninstalled a bunch of bloat and lowered brightness more and have it at 2 days with light use.
I'm trying to figure this out as well. Although I can very easily tell the difference with power savings on, it DEFINITELY takes a performance hit. If it nets less than an hour improvement, totally not worth the performance hit.
I was able to make it all through today and finished with 28%, all with power savings off. I think the auto brightness tends to keep the screen a little too bright for indoor settings, so I turned that off and went with a nice low level.
I might try power savings without the CPU limit option checked. What power savings is applied to the screen? Is it just refresh rate and brightness?
I noticed a difference when using screen power saving. The description says it causes slightly lower frame rates which I haven't actually noticed. But I did notice lower battery usage from the screen.
I didn't want to touch the CPU savings because I don't really want to sacrifice performance to save battery.

Well today I started using juice defender and battery life is looking great.

I kept my phone standby for 9 1/2 hours with Wi-Fi ,sync opened and in that time my 10% was drained......then I kept the phone on standby for the same time period and this time power saving mode was on and Wi-Fi and sync were off but the battery drained was the same 10%........... so does this power saving mode really works or is it just........

For me is working just fine, I get like 15-20% more battery time with Power Saving mode ON
You can't possibly notice it when your phone is in standby whole time. You can notice your battery drains slower when you actually you using your phone. For example it lowers max cpu clock, which means if you use your phone, your max cpu clock will be lower than default values. in standby its always low so it doesnt affect battery drain.
* it depends on your power saving settings.

that's the reason it craps out when playing dead trigger or asphalt7. That time I switch off PS mode. Other than that it helps in the sense that it allows the battery to drain slower.
I really haven't found any use for the power saving feature. It slows down games a lot and it doesn't have any use when the device is idle. Dilemma, dilemma.
Power saving works wonders for me.
Try having endomondo recording workouts and listening to music with power saving off and on and then come back and tell us it doesn't work
Is my battery drain normal or do I need to change my battery

In standby battery uses 0.5%-1% per hour is normal.
No m8 your battery is fine. Gone are the says when I could get 6 days outta my old Nokia 8800

Power saving mode is awesome everyday at work before i start my shift i leave my phone on power save mode. I make calls and use whats app with power save mode on. Whatsapp i just switch on data but leaving power save on. Anyway my battery is still 70 to 80 percent by the end of my shift..
So maybe it's just your phone for me this is the best feature ever.
Power saving is crap slowing the device as hell
even the app drawer become slow and its stutter as **** with PS :silly:
but its good if someone need to save some battery
Power saving mode does not work for me too.
My S3 was slow as hell and lag most of time.
Yeah same here

If your device was slow it means that PS is working just well, doesn't you think? Mine is fast enougb, even with power saver turned on. Most of time I have it enabled.

Only problem I had with power saving and auto brightness on at the same time is little flicker/stutter of screen after wake up,for which I can't find anywhere weather is it normal or not. Other than that it does miracles.
Hi. Im using an HTC One M8 Internation Version clocked at 2.5ghz
This thread is to know if current users of the M8 toggles the power saver ON by default or OFF and do not use it at all.
This thread aims to discuss what are the difference between the two especially the options within the power saver (conserve cpu usage, lower brightness, vibration feedback, and sleep mode)
But as for some using Greenify + Amplify, this power saver might not be needed anymore. What I am concerned now is the "conserve cpu usage" function of the power saver. Does it greatly affect the battery life when the screen is ON? Using max power all the time does affect our SOT?
Thanks for responses in advance. Good day!
Well first thing first... I know if you are running a custom kernel the power saving cpu conserve didn't do anything for me... The kernel runs at its own max speed and everything.
I haven't checked how it affected the stock kernel
I did some tests when I first got it.
The saver limits your CPU at 1.2 GHz. This is the biggest save except the brightness but it doesn't translate into too much battery use. At most you go from let's say 10% per hour of screen time to around 13%.
If you really need the battery I say stick with the extreme version.
Used the power saver at the beginning. The phones battery life wasnt that much better, on the other hand the performance didnt get worse either. I dont believe that it really helps that much, ...
if you don't really like your battery life, you cand consider changing your rom.. some of them have huge improvement in battery life
When I was on stock when I bought the phone used, I tried power saver and it did help battery life a bit but I never measured it. Performance drop was barely noticeable either though. I ended up just using it at night in case it helped deep sleep. Now I'm using VoIP for phone and text so there really is no deep sleep anymore on my phone with that stuff running and data always on, however I still get through a day no matter what rom or settings.
So I did some benchmarks with my new 6p(stock and unrooted) and for some reason the phone got better results from 3dMark with battery saver on compared to battery saver off. (1609 with battery saver and 1491 without battery saver.) Is there a reason why battery saver helped the phone get better scores?(I can't post the picture since i'm a new member. If anyone wants to see the results I can pm.)
