Battle of Battery Saver!

Just a question for those who having the same problem with me, please share your opinion.
Green power premium vs JuiceDefender Ultimate vs Power Max
i'm stuck on this 3, any of you have better idea which is the best for battery?
i tried JuiceDefender Ultimate before and i'm not really satisfied with the result. Please note, i'm running Exchange email for daily use and required data connections.

Don't use any of them. They all consume your battery.
Try this:
Set your display brightness to auto or dimmest. This usually consume the most of your battery.
Download a data switch widget or toggle from the market. I use the dataswitch from tomatoX. Turn off your background data when you dont use it. Turn it off at night or sleeping.
Turn off your gps or wifi when you dont use it.
If you are rooted, you can also edit your build.prop wifi scan intervals to higher number (for ex: 120)
You will find by applying some of these changes, you will extend your battery life.
have fun

I also find that using ROM Toolbox to Disable some apps that start up on boot helps too. Google Maps is a battery killer for me (at least thats what I find) it seemed to start up on boot and eat all my battery so I disabled it.
You might find disabling a few more useless apps helps too.

Just curious if you've actually tried these for yourself or if you're just quoting "common knowledge"? The reason I say this is I've been using Green power for about 6 months now and it gives me a noticable improvement in battery life. Yes, I know I can manually turn off wifi and/or data when i know I won't need it, but green power does that for me automatically. I tried juicedefender for a little and didn't really like it, and I've never used the third choice. Green Power has the best free option that I've seen, it gives you full functionality while Juicedefender free is a limited function app. And if you're wondering yes I've tested my phone both with and without green power enabled, several times. Each time results are the same, at least a few hours extra time at worst and at best it's nearly doubled my usage time.

Here was my original post...I do use it daily
http://forum.xda-developers.com/showpost.php?p=19925664&postcount=26.
recheck the thread.

Not really sure what you're saying to me? You give good suggestions in you're first post, my point is that using green power will do all that for you automatically and definitely does not use more battery power.

if that works for you, then that's fine.
green power is loaded into memory and may actually consume battery as it is running in the back ground.
my point is that many programs with data syncs are unknowingly shorten your usage per charge.
turn off your back ground data..saves data and battery usage.
try this: use your green power for a few days..see how long it lasts
then try the dataswitch on the green power and without the green power and see what it does...
carry a spare battery also works

[Q] what is sleep state?

As the title asks, what is it? I know that turning off the screen with power button is not sleeping. I believe it is the state when it takes more than a second (lag) to unlock the screen. This means that the phone was in sleep state and I woke it up. But the question remains, that what is it? How and when is it activated? What happens when the phone is sleeping? Effect on battery (I believe it's positive)? The notifications like sms and call? Is only the screen asleep or are the other functions sleeping as well? Final question, Can I activate the sleep mode with the help of an application if it helps save the battery?
Note that I don't want to use battery saver apps because I don't want anything on my phone to stop. I paid for the whole phone, "including" gps, wifi and things like that. Smartphones are for us, we are not for smartphones.

Technically; sleep mode starts the moment the screen is switched off. With the exception of applications which can prevent the phone from fully 'sleeping'. A good and obvious example is the music application which keeps the phone awake in order to play music.
There's really nothing special about sleep mode except that the phone will execute a lot more tasks together but less frequently in order to save power, so you're still able to receive all messages, emails, calls and all notifications (from apps). Applications can also be informed about the change in power state (awake to sleep and sleep to awake) and therefore change the way they behave.
The amount of sleep time the phone gets is dependent on the apps you have installed and the amount of emails, calls and other notifications you get. There isn't a way to enable 'sleep mode' with an application as it would make little difference if your display is on. Your display is the main cause of power consumption, as is true with all smartphones.
Battery Saver apps are dangerous, by killing apps they have a negative impact on the phone. If the application is needed, the phone will restart it and add to the CPU cycles. The same goes with memory freeing apps. GPS/Bluetooth/WiFi are there for when you need them. Keeping them on when they're not needed is a waste of the phone's resources. As the more CPU cycles they use, the more power they consume.

That's a good explanation
I have read about term "deep sleep" while searching for this, but the explanations on the internet are not clear to me. I have understood a part of it, that this state comes when phone is at rest for too long. The phone pauses apps and their processes, except those who are downloading e.g games and only does basic tasks such as incoming communications (message, call etc.) and sync. Again, I could not find answer to when it state/mode starts.
About GPS/Bluetooth/WiFi: I said this because I had seen people talking about how they have to force otherwise unnecessary restrictions on them and thus have to worry too much to save their batteries. This is what I don't like. Technology is made to facilitate people and to make their lives easy, that's what I believe. On the other hand, I always keep bluetooth off because I need it very rarely. Well, you may have other preferences but I have to keep gps on in order to geo tag photos and to make it ready whenever I open maps etc. Wifi according to me is life blood of smartphones. So I can't live without it either.
When I had Nokia 5800 I had to turn off auto rotate because its menu took time to refresh if I turned the phone by mistake. That was the time when I came to know how bad it feels to go through the settings to turn it on when I need it urgently.

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!

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

Android seems frozen with black screen

Android 9 on a Samsung SM-T290 tablet.
Had used my tablet, turned off screen (click Power once), and put it down. Some unknown time later, picked up tablet, clicked Power once, screen did not come on. After clicking Power a few times, held Power down thinking somehow tablet had shut itself off completely. Instead of booting, I got the choices "Power off / Shutdown" and "Reboot". Shutting down and rebooting worked. No sign of problems.
Some time ago I noticed my Uptime seemed large -- I think 400 to 600 hours.
What would cause Android to get itself into a state in which it is still running enough to offer a Power Off menu, but in which it refuses to light up the screen?
In particular, is there any problem with running too long without shutting down and rebooting?

My guess is that in your Android the Doze mode is enabled.
FYI:
Starting with Android 6 Marshmallow, the Doze mode feature was introduced. This feature is designed to give a new breath of fresh air to battery consumption and in general battery life.

No match when I Search Settings for "doze".
Under Battery -> Settings there is an
Optimize settings​Save battery by optimizing your settings when you are not using your tablet.​It's a toggle, it is toggled OFF.
I think at the moment I turned off the sceeen, I was im a browser on an obnoxious web page. Maybe their clever Javascript tied something into a knot.
I'll try to notice when I pass 600 hours of Uptime.

If it has the doze feature, it would be a background process that you would see no controls or settings for. It is a feature in the kernel that runs at and below system level and you can't "see" it if you look for it.
Doze puts the device to sleep, it effectively freezes everything from the kernel level all the way up through system/user level and turns everything off without actually powering down and stays in that state until you "wake" it.
An example would be a Kindle Fire HD tablet that I had with doze, I forgot it was on and running a PSP emulator and I put it in a draw for many weeks, when I pulled it out of the draw and hit the power button, it woke right back up straight to the enulator and the game I had running and still had 60% battery.
