Is my Note Pro Lte losing power too quickly?

[hajime_android]

Hello, two days ago I closed the lid of the cover and put my Note Pro LTE in a bag. I just took out the device and found that there are about 81% left. Is this normal?

Depends on what you're running in the background.

Mine looses about 1% every 24h when in deep sleep. I've got everything turned off, including sync, gps, wifi, mobile data (I'm not using a SIM yet), most of the bloatware including touchwiz.

So, even I closed the cover, apps were still running and the power hunger ones continued to consume power?

Just check the battery stats...

Power hungry, no; but background processes still run like email checking and other sync services.

Considering you probably have sync set up for an email account and Google play services is likely running as well getting about 0.5% drain per hour seems reasonable to me.

Turning the screen off doesn't disable Sync. With Sync enabled, it keeps actively checking for new emails and the lot. Think of it like going to sleep, and waking up every 5 minutes to check your mailbox.

It temporarily pauses games and videos, but it doesn't quit the app. You have to do that through the recent apps menu.

Is there an app that also put those sleepless apps such as sync to sleep when the lid is closed?

When it comes to battery life the first thing to do is get a handle on what your current drain is.

Monitor your battery stats page, look at the times that the device wakes up and at the rankings of applications to see what's using the most power. Third party applications can help here like Better Battery Stats or GSam Battery Monitor.

From a fresh clean boot with a full battery let the tablet sleep unplugged while on WiFi without ever opening any applications or turning on the display. Let it sit like this for at least a few hours and determine your average hourly % drain. Use this as your baseline and see what applications rank near the top. Repeat this with WiFi turned off and the tablet on LTE. Compare the two and if you see higher drain on LTE take a look at your signal strength. Most likely if LTE signal is weak then drain will increase as the radio tries to compensate.

If you see more than a percentage point of drain in deep sleep while on WiFi then chances are an application is keeping the tablet awake or waking it frequently. Those applications will likely rise to the top in the default battery stats page. If not, the third party applications can assist you in figuring out what's wake-locking the device.

Thanks, I will try the test under wifi. I haven't used LTE yet. I bought the LTE version because it has faster processors and quick charging.

Do the tips mentioned in the article also apply to our Note PRO? Do Airport Mode turns off those apps we talk about?

Since 4.3 Samsung OS has a process called Index (from indexing files) draining a lot of battery juice from its first start till completed process (just for 2 days i think).

I had noticed this since Note 2 update to 4.3, and now with 12.2.

But I can be wrong......or not.

Seems fairly logical when you think about it . . if you're trying to fill a bath tub it will fill much faster if you close the drain at the bottom . .
