Best Battery save app

Hi Frndz i came across this app n it really really cool... a must try for all battery savers and it works like charm
https://play.google.com/store/apps/details?id=com.eugene373.cpu.sleep&feature=search_result
NOTES BY AUTHOR
### Attention, Root Required Application!! ###
What is it?
Its a fairly simple App that will put CPU 1/2/3 OFFLINE when the screen turns off. Once the screen comes back on, it will allow CPU 1/2/3 back ONLINE.
How does it work?
Since we have Dual & Quad core CPUs, we have a CPU 0 and a CPU 1/2/3, core 0/1/2/3, while the screen is off we really only need to have 1 core active "CPU0", this App will make sure CPU 1/2/3 shuts off while the screen is off, then resumes normal usage when the screen comes back on.
Compatibility?
Works with any Dual Core & Quad Core Devices!
Battery Saving?
Battery savings all depends on Usage & idle times.

Trying this. I'll post my report later.
Thanks for the info

thank y:good:
have by it :angel:

The sgs3 already shuts off the other cores. That's what hotplugging feature of the kernel does.

looks promising but can someone report back to see if this app uses up much battery itself in BetterBatteryStats, if it doesn't ill certainly purchase it.

I have WiFi and Sync on and my battery do not seems to discharge (I don't know if it was already like this before, but it's impressive)
I'll deactivate this, try the same experience, and post a screenshot of the result
I don't really like the power saving mode, but I'll try these options

Well does it still sync all the stuff it is supposed to with this tool enabled? (Gmail, Twitter and what not?)

Its important when testing this app, to ensure you do not use powersaving mode.... I bet powersaving mode is actually doing ALL the work and the app, nothing.
OR, first use powersaving mode without the app.
What the OP is suggesting is you use the APP and powersaving mode. Well of course powersaving mode saves power (the clue is in the title) so how can anyone tell how good this app, (that simply turns off the cores like the SGS3 already does) really is?
It costs money too?
What?!

Oh THAT eugene. These threads have been locked countless times and it has been proven several times it has been useles son teh SGS3 as it already does this.
Here is our thread we already had on this:
http://forum.xda-developers.com/showthread.php?t=1745493
Lots of technical reasons given by a kernel developer as to why this doesn't work and even why it is bad for your phone.
Yes, but this is the best response from the dev.
http://forum.xda-developers.com/showpost.php?p=28161249&postcount=13

It was just an illusion.
This app did nothing on my battery life, the S3 has just a huge battery life. I noticed that during this short period (~4hrs) my battery life is rather a little bit worse with this app activated.
This app is definitely useless

Thanks for reporting back, i shall not be purchasing this app

Reccomendations for a good battery saving app

I have noticed there are so many battery saving apps on the Playstore but do you have any reccomendations for a good one
Sent from my GT-N7105T using xda premium

Just install greenify. I have tried plenty before I had Note II, they've had little effect and I often had issues with many of them. If needed use power saving mode + greenify. Why, are you getting crappy battery life?

If your rooted install Redpill Kernel no need of any apps ,
Again for Greenify you need root but this is also suggested app ,
If your not rooted , You could try Juice Defender Ultimate from Playstore.

I'm not actually the battery life on the Note II is very good probably one of the best out there on a mobile phone, was just enquiring
Sent from my GT-N7105T using xda premium

Yes just use greenify and maybe fast dormancy toggle for disable it. It was the 2 best thing for a rooted device i done.

All these apps are a bit useless to be honest. The most important thing is just to set your brightness manually, enable/disable all the functionalities like GPS/W-FI/BlueTooth etc only when needed. Also setting your mail-account to sync once in the 2/3 hours, instead of 15 minutes helps alot also. If you are rooted, you could also remove some Samsung/Android Apps that basically do nothing apart from using battery.
A app to close the processes of application will help also. But if you want to try a battery-save app. JuiceDefender Ultimite for Rooted Users, GreenPower Premium for non-rooters.

Greenify.
You won't need anything else.

What does juice defender except turning off the data when screen is off ? If it's only that you can also do it manually.
Greenify is useful for lot of user and app which use data or process even if you disable synchro like facebook.

i installed greenify the other day and hibernate fb. but it was draining my battery when the phone was supposed to be sleeping. i then removed it and its back to normal.
just my 2 cents. xD

I was so lazy to say this. Good thing. Thanks!

Well another point of these Battery-Saving apps. They could make your phone unstable. You can set manually the sync times for Facebook, E-mail , Weather Apps etc. Greenify works pretty good. It is basically a program to put the processes on the background on hold. When you use that application , it restores fast the proces (where it was). Handy for FB etc yes. Although sometimes you can see a small delay (hick-up) when you open a app that was Greenified.

If i have 2g on, i barely lose battery when the phone is in deep sleep. when i leave the phone at nite and wake up in the morning i lose like 1% or 2% max. but with greenify every time i was leaving the phone in deep sleep, i was losing like 2% per hour.

i will try uninstall greenify

Ok looks like Greenify will only work with rooted phones so looks like I cannot use it

First two points are not disadvantages. They are just features not added by Sony.

Disadvantage is only 1080p recording for me.
Battery life is amazing so no need for stamina: http://forum.xda-developers.com/showpost.php?p=42046505&postcount=1646

Only disadvantage is 1080p video recording, and shutdown time which is a bit slower than before. Everything else is improved compared to ICS.
The camera has always been like this. Learn to use the advanced options to take better pics.

No Encryption Support
ICS did not have encryption at all. With JB, my corporate email required phone to be encrypted confused not sure why. But the damn thing does not work. No progress.

stamina mode it's there on my xperia s,it's called extendended standby mode

On my Acro S same, 1080p is WAYYY too laggy
Backup and restore app didn't restore SOME OF my games' progress, like Temple Run 2... anybody here with the same issue?

That's not Stamina mode, that's Extendended Standby Mode. [You'd think this was obvious.]
As the names would suggest, they're different things

Nope. The fundamentals are the same. Extended Standby Mode blocks all data to your apps after 10 minutes while Stamina Mode let you choose which apps to block or not block. Other than that, there's no differences.

Performance wise the firmware is great, but they did not fix the bugs that we found on the first leaked version.
For e.g. Default keyboard settings does not hold up after reboot, i have to set up SwiftKey everysingle time i restart, also, admin privileges for a specific app are also not being saved, my kaspersky antitheft simply does not work because of this.
I do not understand why myXperia was not added.
When the leaked version came up i really thought sony did a nice job, but the more i use, the more it seems that they released it just to shut our pie holes
Do you guys think these are fixable on a custom rom?

WIFI Problem In Iran
Beside all of the mentioned bugs, there are two regional bug for Iranian users!
1- Wifi does not work except you switch to Airplane mode (or remove your simcard)
2- Mobile data netwrok does not work at all!!

[Q] [Battery Drain] Android OS sucking a lot of battery

Hello,
From the last 2-3 days my phone's battery life reduced by 4-5 hours. Upon checking I found that Android OS is taking a lot of battery (Image attached). I have just a couple of sync settings on. Its also keeps the CPU awake. Please suggest any way to stop this.
Thanks

When did this happen? What did you do anyway that made your Android OS blow up the roof?

Thanks for the reply, I ain't on CM11. Just the stock rom with gravity Box Mods.

44% is too much. Which FW you are using? And are you rooted?
If yes set lower CPU when screen off, that saves battery a lot, n did you turn stamina mod on?

Thanks for the reply. I am using Stock 4.1.2 Build 15.1.C.2.8 (Fully Rooted with busy Box). How to set lower CPU? Also, I don't use Stamina mode as I get a lot of Emails and I need push notification to work for that. Any other solution that you can suggest?

You can use Stamina mode with push notifications, just whitelist the apps you need working with screen off...

Go to stamina mod and add apps you want,like gmail,whatsapp,etc,and then turn on stamina mod
Am using du battery saver pro there you get option to lower CPU frequency when screen is off,
And also I recommend install greenify and put apps which you use rarely,

i am generally using lowest brightness. gps/nfc/bluetooth closed all time and i am rarely using 3g. but i couldnt see 2 days and if i play games etc. even not 1 day. when i look a games informations, force close button always clickable.(to after reboot.)(death moto,chess free in fact almost all apps.) what is the problem ?
edit: my phone is rooted.

Did you enable Stamina mode? You could also try Greenify...

i am using low battery mode.(second option). when i activated stamina battery is finishing so faster. i couldnt understand. for example from night to morning %20 using battery.. with just second option %2-3 .
and i am gonna look for greenify. looks good.
can you suggest a cpu controller ?

You can't control CPU with the stock kernel. Something is really wrong, check running processes, something may be running constantly in background...

I've a solution which you could try....
Root is must
#First convert fb app to user app via titanium backup
#add it to list of greenify
#keep stamina mode on I am getting 1 day backup easily
