What is "deep sleep"?

[Joe113]

What does this term mean? And how do I know if my phone goes into it?

During the night when I am not touching my phone, the battery stats shows my phone randomly being awake.... so does that mean my phone does not go into deep sleep? Thanks.

It likely wakes up to sync.

"DS Battery Saver" can change that--> https://forums.androidcentral.com/e...m.rootuninstaller.batrsaverpro&token=MAEAeJtA

99.999999% of "battery saver" apps, kill your battery even more LOL, so I'll pass.

While I usually agree, this one had me go from 8-9hrs without it to 11-12hrs with it after 10days of testing both cases.

Cool. I already avg 52 hrs per charge (Hyperion ext. battery). So I don't need an extra 2 hrs, I just wanna know what "deep sleep" is.......

It's likely what he said your phone is waking up to sync and stuff.

The term deep sleep just means your phone isn't awake so it's using the littlest amount of battery to stay running. It wakes up to sync an email or if it receives a text.

After reading the app description, I'm not surprised it saves battery. But it also means you won't receive most notifications when the screen is off. I'd rather charge my phone a little more often and have it work like it's designed to, with real time notifications when an event occurs.

Whether your phone is "asleep" or even turned off, you'll still receive all your notifications when you "wake up" or turn your phone on. That goes for missed calls, as well.

Umm, yeah. But that's not what I said. I want to be notified when I get a text, or email, or some other event is triggered. I don't want to have to remember to take my phone out of my pocket and check to see if someone is trying to get in touch with me.

I agree with you Meyer. I don't have a smartphone so I can remember to check what I got every hour. I like when it notifies ME.

What's the fun in having a smartphone if you are worried about battery insanely? I could maybe see if your away from a charger for very long periods of time.. But if it's a few hours... And your battery drains... Well... That's why the battery is there.. To be used

Used it for a day, messed up my WiFi and mobile data signal so that sometimes when my screen was on, the mobile data would cut off

Saved me 0 battery and and had to uninstall

To save a little battery you just turn off sync when you don't need it. There is a background sync toggle in the pull down settings.
It works!

In a way no one ever answered your question.

Deep sleep: turns your phone CPU *central processing unit ie brain* to the lowest clock cycle speed. On mine it is 200mhz, where max is 1600mhz.

it also disables some sensors it figures you might not be using, such as *dependin on phone* camera, gyro, etc. some of it gets shut off to save power.

When you wake up your phone *depending on governer*, it rams cpu clock cycle up to 500mhz, or 800mhz, or 1600mhz, and re activates the sensors, sending power back to the camera, cyro, magnet, etc that your phone may have *proxi sensor*

This is more or less what deep sleep really IS. program, to save power, by disableing unused sensors, and clocking cpu way down to minimum.
