Discovered amazing battery saving application: Deep Sleep Battery Saver

[Nick H. Supervisor]

Not low at all? Jeeze, I steal free stuff :|

...I honestly have no idea how that works. How can you steal something that is free?

Anyway, it's all beside the point. The problem isn't that I don't have the money to buy the app, it's just that my details aren't on Google Play and at the moment I don't plan on doing so. If I wanted the app badly enough I would buy it.

There are a ton of these apps out there and there is nothing amazing about it. You sacrafice push updates/notifications, background data transfer, being able to see the screen etc. What good is crippling your device just so it lasts a few hours longer.

There's not a single app out there that does what this one does (and it does something simple). If you want to compare it to something, the closes thing is iPhone... but better. Better because it actually doesn't disables background syncing functionality when your screen is off. It limits it in a configurable manner to your need. Read the description: "During deepsleep mode, Wifi, 3G are turned off, background apps are stopped. Therefore, most apps are not working, including Facebook, Google Service, etc,. It then constantly wakes up in order to download email, sync Facebook status, etc,. It's defined by deepsleep frequency and woke up duration"

Or just look at this pretty picture:

And really, not just "a few hours". Check the screenshot I posted in the second post.

might be useful for some but I kinda agree with most other people here it somewhat ruins the point of having all of your push apps which is the main thing smartphones are used for.

I just don't understand you people. How does this ruin it for you? Don't want it to shutdown your twitter app? Just white list it and let it run in the background, draining your battery while twitter itself is configured to sync every 30 minutes by default if you haven't changed it. Leave the better option of this application turning the twitter application off while the screen is off and then let it turn it back on ONLY when it's time for the sync function to be executed :rolleyes:

Intrinsica, go to that xda link, he provides the apk for the pro trial right there, so you don't have to enter any bank details into the play store

The best way to get better battery life without using a separate app is to just root your phone then find a good custom ROM and be done with it.

I'm using an international galaxy note with cyanogenmod nightly and I get 2 days between charges.

Deep Sleep that is built into Android is good enough for me, just make sure you don't have any apps configured to cause a wake lock and you should be good to go, you don't need to buy extra apps. I have Galaxy Note that can go for at least 24-48 hours without charging even with massive screen.

But doesn't that phone have like a laptop size battery in there?

How does one make sure they dont have any apps configured to cause a wake lock?

I've got the Rezound as well and I can get some great battery life on it. Not sure if you run custom roms, but if you are rooted, one trick you can do is get SetCPU and create a profile to seriously underclock the cpu when the screen is off as you probably don't have much of a need to get things done quickly when the screen is off.

my phone is completely stock. For some reason, today, my battery is <15% after 9hrs. i havent even used the phone today, aside to look at a couple emails.

I get the same thing with CM10.1 aka 4.2.1 without tewaks ... think it is called deep speep ...

also keeping your phone screen off helps a lot

I've used JuiceDefender since getting my phone and find that's helped me well enough. :)

I use BetterBatteryStats to monitor wake locks.

I use BetterBatteryStats to monitor wake locks.

i use that too, but what do i do after monitoring?

Check what process wakes up the phone the most and see if you need it. If not, disable/uninstall it.

I'd rather leave everything on and still have acceptable battery life - like with my iPhone 5. WiFi and Bluetooth on all the time, and push notifications enabled for every app. Battery easily lasts the entire day.

i just checked my phone - in BBS, i chose "partial wakelocks" and "since unplugged". it says the top 2 offenders are "AlarmManager" and "SyncLoopWakeLock" taking 8.4% and 5%. Im not sure what these really are. i assume the latter has to do w/ syncing email and the like.

if i change to "Kernel Wakelock" and "since unplugged" it shows - "vbus_present" and "battery_daemon" taking 45.7% and 45.7%. Anyone know what these mean?

[Gaffney]

My HTC 8X can last 2-3 days when location services and data connection are turned off but leaving the wifi on so e-mails or any other notification can get through.

I use to have JuiceDefender, but battery life was WORSE when the screen came back on. I mean, I literally saw my battery level drop blocks at a time for no reason. Therefore, I'm hesitant to try more of these things. However, I do use CPU profiles to automatically underclock the CPU when the phone is asleep. I could probably get more juice if I disabled WiFI/GPS/syncing, but then I wouldn't be using a smartphone anymore...

[Sir Topham Hatt]

I used to use JuiceDefender but decided it wasn't that great. I found when turning the screen on, sometimes it too a while for JD to turn the 3G back on.

Since un-installing I haven't actually noticed any difference, my battery still lasts about 2 days.

I like the idea of my phone disabling everything when the screen is off, then every hour, 30 mins or so, checking and syncing everything.

I might give this a go :)

Seems some of the permissions are strange. It needs permission to make a phone call?
