Description
This is a homescreen replacement that has an Ultra Power Saving Mode for your phone to help you extend battery life when you are running out of charge. This launcher allows up-to 4 apps on the home-screen.
What this app does:
1. Kills all running apps and services.
2. Disables WiFi, Data.
3. Shows Missed Calls and Missed Messages.
Ultra Power Saving Mode:
4. OLED Mode for AMOLED devices.
5. Changes governor to Powersave mode. (requires ROOT Access)
6. Disables 2 cores of a Quad core phone. (requires ROOT Access)
7. Reboot during exit. (requires ROOT Access)
When your phone goes below 15% battery, the app shows alert to clear the defaults for your current launcher. After clearing, set SOS Launcher as the default homescreen, and the app would take care of the battery. Once you quit the app, it would clear itself as the default launcher and you can start using your favorite launcher back.
Please post in features that you might like to have on the app.

not a bad idea.
can the alert at 15% be turned off?
I'd use tasker / secure settings to make this change on my own at a lower battery percentage

Couldn't this be done with Tasker?

And from the screen shots, it will not save you any power. Amoled only save power when they display BLACK, not greys. I don't want to get into the science, but only complete black saves power, like the status and navigation bar. Don't bother with this app, because it will not save you power, and it kills tasks. Killing tasks is bad in Android. Just avoid this app and similar apps.

You are right and I should have tried before commenting. But my second point still stands. Killing services in android does not save battery, processing power, time, space, ram, anything. If anything, it uses more power restarting essential services. Android is based on Linux, and Linux is the best operating system for managing ram. It does not need any third party apps to help it. Killing processes in android is only bad. It was bad in froyo and eclair when we saw the huge influx of "task killers" on the market. If anything, it is worse on JB and KK, because the ram management has only improved. You would get a much more tangible benefit by installing greenify and greenifying your apps. This actually fixes badly coded apps rather than killing them. Killing tasks just aggravates the problem more.
Other than that, it looks like a nice app. It seems to do what it was made to do. I personally will not be using it because I would rather fix the problems with my battery life rather than stretch to the next outlet, but the concept is sound. Please note that the market screenshots are very badly done. In apps that have a setting to change the entire UI of the app should definitely have screenshots of all or most styles. Screenshots are the first impression a user has of your app, and first impressions should always be good. As a very "technological" user, I understand that I am a minority in your userbase, but it is not good or fair to exclude any parts of a group when it would be very simple to include them.

Honor 6 EMUI Power Saving Actually Worsens The Battery...

I've generally been happy with my Honor 6, but one thing thats irritated me is the inbuilt power saving - how it's constantly informing me that certain apps are consuming power, or how it causes conflicts with actual working power savers like Greenify and Amplify.... even when they are whitelisted I still have problems (with Greenify especially). IMO It's fairly obvious that all that background management is actually going to have a negative effect on the battery, not just when it's constantly checking for 'high power apps' but when you need to reopen the closed down ones again. And with how Android actually works, there's actually no need at all for battery saving apps that are constantly freeing up memory in the background!
Yes there''s the ultra saving mode, but that disables much needed features and (for me) can't be switched off without fully rebooting the phone. And yes, you can switch the power saving to 'normal' but I'm not sure if that still means it's trying to do background management?, so last night I decided to find out if I can fully disable it. and it turns out it's called 'Phone Manager 3.30.20' (you may have a different version depending on what you're running) and that it can be frozen via Titanium Backup... it causes no negative effects when disabled and just disappears from the settings menu altogether without needing to reboot.
In the attached image... after the dip around 55-60% where I disable it you can see that although not making massive improvements to the battery life it has improved it somewhat :good: Worth a try if you're OCD like me when it comes to battery life!

Isn't permissions manager part of phone manager?
Do you still have control over apps permissions?

Well all apps which i constantly use and don't want power manager to notify, i turn off the power notification for that individual app. And then removed much of the annoying part.

Interesting app. I installed it on my tablet. Look up how it will work. Pity that application is not in material design...

Can I say dodgy app here full of ads and nothing as you say it is. Gives me to play games and full of ads. Avoid

Looks very Good though

Full of ads, nothing like advertised. Avoid.

i want to prevent apps to auto start to save battery and ram, which app should i use, grrenify or autorun manager or any other?

First, you need not concern yourself with free ram on an Android device. Android manages resources better by itself. As for the apps that launch on startup, you can got to menu>settings>apps and select the "running" tab to show you exactly what is really running. Then, the easiest way is to uninstall the app in question.
Automated task killers do nothing but cause more problems than they can potentially solve.
You might find this thread enlightening.

The task killer discussion gets old. I think there is risk of oversimplifying both sides. ie on one side people want to treat it like pc...not correct. On the other side people seem to imply any discussion of memory management considerations is irrelevant/rejected because "android will handle it all"....which is not always entirely correct either. The latter may be closer to the truth especially for new devices, but there is still room for middle ground. Not all programs are equal, some launch "services" which takes priority over other app processes. Too many of those services can eventually crowd out cache and slow your phone down. Maybe most people with newer phones will never get there, but there are still people with older phones (including the op for all we know) and also some folks with new phones who (if they listen to the oversimplifications) may get carried away on the number and type of apps they install over the life of their phone
---------- Post added at 12:47 AM ---------- Previous post was at 12:43 AM ----------
Even so, killing off those services is not the answer. If an older phone has too many running services so it taxes it's resources then it's either time to uninstall some or get a device that can handle it. If it's a problem with the app itself hogging resources, then let the developer know and find an alternative.
If you try to tow a boat with a bicycle, the answer isn't to throw away the boat's engine to make it lighter. Similarly, a task killer may make the phone's performance improve briefly, but over time it will make things worse. And it fixes nothing.

An app preventing another app from "auto-starting" is a task killer. Look at it this way: The phone boots up and runs it's processes. The auto-start blocker detects an app it doesn't want to run, so it kills it. Now, depending on what app it is, the phone may call for it again and thus running it later, which defeats the purpose of an auto-start killer, unless that app is a task killer which again kills said flagged app to keep it killed.
The way to properly manage an app you don't want to have enabled on the phone at bootup is to disable the app on the system manager (newer phones have it AFAIK), freeze the app via Titanium or similar apps, get into the app settings and disable certain features like auto-sync and set everything to manual.
However, the OP did not specify what phone and which apps. It may be apps which the phone requires to run at some level, like Maps (which several apps call for), or maybe the apps he is seeing are just RAM cached, which really don't matter at all.

Adjusting with app settings is preferred if you can, but does not always solve the problem (I referred to wakelock/battery drain problem with a certain version of Maps on my previous phone ... many people we having the same problem at the time and the only way to stop it was to block the app from starting as indicated in link below, or else to freeze it). Freezing has the disadvantage that you cannot run the program easily (requires you to launch TiBu to thaw the program). If you have blocked the program from autostarting, then it does not start at boot or other automatic time, but it remains available to manually launch the normal way (clicking the program icon). At that point (if it's a program like Maps), it will probably stay running until next reboot. It was my preferred solution when maps was giving me wakelocks and battery drain on my phone. Maps didn't run automatically on boot and never started until I manually started it. After that point I could live with the battery drain or reboot

Rom Toolbox Pro is a great app with many features and of course, there's an auto start manager that allows you to disable various receivers off the apps that start on boot. There's also a freeze/deep freeze feature as well. Great app

App optimization - What is it & why does Smart Manager change settings UI?

Most of you will be aware that a new "app optimization" feature was added to a recent 5.1.1 based firmware update.
I've been trying to research exactly what this does because Samsung have not updated their user manual (you can access this via the user manual widget) to cover this new feature. After searching online, I've come to the conclusion that I'm not the only one who isn't sure what this feature does and there's a lot of incorrect information out there.
Below is some examples of what I've read:
It's Samsung's implementation of doze - I think this is incorrect as doze is a system wide state that uses sensors and screen off information.
Someone on AC forums was told by a Samsung employee that for example, it will make taxing games black and white so they don't require so much processing power - I really don't think this is the case.
It's Samsung's implementation of app standby - I think this is the most likely.
Does anyone have any concrete evidence as to what this setting actually does?
Furthermore, I've noticed that the "app optimization" implementation will change depending on if you have Smart Manager enabled or disabled. Not only that, but the battery sub menu layout (settings > battery) is also different depending on Smart Manager running or not. Has anyone else noticed this?
From what I can gather, the "app optimization" feature is there regardless if Smart Manager is enabled or disabled, but you can only manually select wether an app is optimised or not. Smart Manager appears to only provide automation of the process by monitoring which apps have not been used for x number of days and then changing the optimisation setting for each app for you.

Based on your screenshots, system apps can now be optimized by default?

Second screen is the 'Optimization Screen' under Setttings > Battery > Battery Usage > Battery Optimization. First one is from the 5.1.1 update, and the second is only present in Marshmallow Beta.
I don't think it's exactly an App Standby, as this keeps the apps 'unoptimized' if they have background services. Samsung's optimization only takes days since last usage for determining if an app should be optimized. Also, I think Samsung's optimization is more aggressive, like Greenify, an it shuts down apps shortly after user lefts them.
Oh, and it seems that you can't explicitly turn App Standby for an app, like you can do it with the Samsung alternative. Putting an app on/off on App Standby only activates App Standby for that app (If conditions are met) or disables it completely.

You're not quite correct on the screen shot front. All screenshots were taken from Android 6.0, the reason they're different is one was taken with Smart Manager running and the other was taken with Smart Manager disabled via Package Disabler.

What it does is that after an app has not been started for 3 days (this is configrable), it freezes (disables) it.
This is really problematic for small apps acting as unlocker of a main app and not supposed to be launched by user, as it prevents the main app to communicate with the unlocker app (bindServices() fails), preventing license verification to work.
This cancer acting in the back of apps used to only be possible on root devices, but Samsung generalized to mainstream devices.
