Hey peeps,
Do the saving modes on Zenfone 2 actually make a difference? It seems to me that Performance mode (runs on 2.3 Ghz) and Normal Mode (runs on 1.8 Ghz) use around the same amount of juice (at least that's how it looks when I look at on screen time) and the last ones (Power Saving and Super Saving) only have network disable turned off, compared to Performance and Normal.
Did anyone test this?

I recently have bought a Defy plus.
Stock 2.3.4 ROM used so far with LauncherPro.
Doing OK with battery life so far, but now starting to look at the CPU over/underclock capabilities. Started with Antutu CPU Master and CPUTuner also.
One thing I haven't seen as yet is the ability to underclock clock below the min 300MHz.. or even whether this makes sense. I guess undervolting is the other option, but perhaps someone can guide me here.
use setvsel to oc/uv, thats the easiest and best app imo. although underclocking your phone below 300mhz may cause instability and makes the phone wake up much slower in my experience.

I agree with zakoo2: Going below 300 will not be a good idea and it will most likely not improve your battery life in any significant way:
My Defy is running between 300-600Mhz and right now the LCD screen is the biggest consumer: Changing the (auto-)brightness settings in CM7 will do *much* more to your battery life than going below 300mhz.
What really helps saving battery life: use setvsel and leave the minimum clockspeed at 300MHz, but set a vsel value of about 20 for it, then scroll down and enable "limit to vsel1 while screen is off".
Also, going below 300MHz will probably make the phone sluggish when waking up from sleep like if a call comes.

im just change from 300mhz to 330mhz lowest. 300mhz will make my defy+ lag when got incoming call. im using smartass govenor.
I heard some guy out there got 80 MHz and running, but I'm not sure of it.
As people said, clocks lower then 300 MHz would make your phone run horribly while waking up (i.e., it would take a long time for the screen to turn on when receiving a call, and you would probably miss it most of the times). Setting 300 as VSel1 and limitting to it while screen is off (2nd-init enabled bootmenu has this option, and downloading SetVSel - free at Android Market - will also do the trick if you have a rooted, but stock ROM) will help you save a lot of juice. Using a lightweight launcher (I personally recommend MetroUI or Zeam) also boosts up batt saving. Last, but not least, setting brightness to auto or minimum (using frosted/mat screen protectors will help a lot while using the phone under direct sunlight) also saves loads of charge.
Obviously, using a light ROM (I think Barebones may be a good option, though I think it's not suitable for me, but it's a personal matter) and calibrating your battery in a monthly basis (via manual calibration - you can find how to do so by googling -, wiping batt stats in custom recovery and/or using the batt calibration app included in most ROMs - but also free at AM) also help.
What does power saver do ??? like it uses only 2 cores..or what ?
i think downcloak cpu also in 1.3 Mhz.
Underclocks to like 1GHz, limits fps and controls wifi and gsm radio to save power.
also says the lowers the brightness..but my brightness stay at the same level..and also..connection data and other things ARE the same :-s.
Perhaps it is designed to be unnoticeable and it's doing good job at it.

Haptic feedback also gets turned off.
Any idea why my phone runs out quicker when using power saving mode? With power saving mode on, 17 hours with 4.5 hours screen on. Yesterday 1d 8h 5 hours screen on with power saving off.
Using cleanrom ace and adam kernel 2.5

It could be the kernel? Power save mode is nothing compared to a well built tasker profile or two. Or even a good CPU profile.

Maybe you have used your phone differently on those days? More screen on time? With higher brightness? Maybe the tasks you did were more battery draining (other games, video recording.... or something else...). Battery saver mode sets max cpu frequency @1000Mhz and that's it. If you check what is draining battery in your phone you will see that at times (full brightness) the screen eats up to 70% of energy so the savings from cpu are negligible.
I have a rooted HOX with everything in stock version. I have tried solving this issue by myself but no matter what I do, it just wont go away.
I get HUGE battery drains whenever I have my wifi on. I don't use 3G or 4G, only wifi.
I thought it's a faulty battery at first, so I ran the battery test on the "HTC Function Test" (by dialing * # * # 3424# * #* in the dialer). For someone who is not familiar with it, it is a test which checks your battery usage in full brightness, screen always on, airplane mode ON for 60 minutes. If your battery discharges below 70% during the test, it means you have a faulty battery. Well, after 60 minutes my battery was at 81%.
I have underclocked the CPU's max speed at 1Ghz and tweaked the "Ondemand" governor a little so it stays more on the lower frequencies. I have also disabled ayto-sync and GPS location options and enabled the Power Saver option. I have also changed the network mode to GSM only (not sure if this makes a difference).
I also used Gsam battery monitor to monitor the battery usage and my "App usage" is the highest battery drain with Kernel (Android OS) always up there in the most apps that use the battery.
What do you suggest I do?
Please can some one explain what are the different power saving modes on Asus Fonepad 7 Me175cg (K00Z) running android 4.3
I can see Ultra/Optimised/Cutomized mode
Please can someone explain the different between them
Do they reduce the CPU frequency or only affect screen brightness and wifi
How exactly do they help?
just what it says AFAIK ultra reduces perfomance of processor so that battery last longer.
