[HOW-TO] Battery saving tips

[dchawk81]

Wifi seems to suck A LOT of the battery even if it's idle. If I'm playing a simple game, there is no way that wifi should be using more battery than almost everything else combined. Unless the battery stats are incorrect....

I believe those stats are relative. It's not necessarily using a lot of battery, it's just using more than other things.

It indeed may be relative but Infinity's WIFI is indeed battery drainer. My reasoning is the followings:

Facts:

1. The battery drain was approximately 10%/hr when I was playing local video or reading ebook WITH WIFI on.
2. The battery drain becomes 20%/hr when I use browser.

Hypothesis:

The way ASUS handling WIFI unit is either giving too much power to it so it won't have the WIFI issue it faced with Prime (as if fixing with part plastic cover wasn't enough) or somehow while it is in browsing mode it unnessary dissipates power by constantly supplying power to wifi.

One potential alternative explanation would be browser is extremely CPU intensive. Though this may partly be true, I sort of doubt from couple reasons. One I did not see much difference of battery drain among different browsers. If it was application related you would think different browser application requires different cpu usage. My current device Galaxy Note 10.1 would not show any difference in battery drain between constant browsing vs. non-browsing activity.

I believe this is fixable by some software though.

What do you expect when you're actually using it? All radios drain the battery when active...on all devices.

Hi

Same here. Battery life on deep sleep with WLAN is great!

But I think the Infinity needs a lot of power while reading news, tapatalk, Reader HD..
Not more than 4 hours Screen On Time!
And that with balanced mode and 50% brightness.

Any problems with the fifth companion core?

PS: Is there an app which shows the activity of the different cores?

Wi-Fi should use very little power in standby, however this depends on the Wi-Fi access point supporting power management options. Most do, some may not, and if not then power drains quite quickly in standby.

These tips have been really helpful for me. Before I would have to charge every night with just minimal use during the day. Now, after recalibrating the battery, using SetCPU for a few rules and stopping the cpu from getting stuck at 1500, freezing bloatware, and changing the startup apps I only have to charge every other day or so.
Wifi still seems to be the biggest drain, hopefully Asus will do something good in a coming update.

Great, I'm glad it helped! Perhaps a new kernel will do something for us in this department too (although there've been various reports on the JB in that matter). I think we need to start whining to ASUS more about these things if we want new proprietary drivers/modules though.

I watched an internet streaming 90 minute movie today and it used about %25 of the battery. I think Asus should have put a bigger battery in this tablet.

nice tips

enjoyed reading it

Juice defender is no good. It disables Deep Sleep.

Great read with a lot of useful tips. Managed to pull off more battery life than before.

Google services is killing my battery while it is sleeping. 40% of battery use in just over a day while left on standby. Battery settings say 96% for Google services and wifi the other 4%.

 

[d14b0ll0s]

Now that sounds like a bug...
I'm aware this is not the favourite choice for most, but have you tried factory reset? Also, does your device (and CPU specifically) go into deep sleep with screen off at all? For most of us WiFi is the first battery drainer and with screen off it's probably sth closer to 1% drain every 4 hours or so...

Great write up and tips.

I have tried some of them already and it really helps!

Thanks!

Question..

I'm near an electrical outlet 90 percent of the day. If I always have the device "plugged in", will that harm the Infinity
or the battery's life in any way?

i think it can shorten your battery's lifespan

Battery stats app shows the culprit is network location services from Google framework. This is keeping partial wake lock and Wi-Fi running most of the time. How do I solve?

You can try using Auto Airplane Mode from Play Store. It shuts WiFi off right away and should also prevent all network services from sucking battery while screen is off.

Thank you, I will try that. Is this common on the Asus?

Personally, I keep wifi enabled all of the time and get very little battery drain while the tablet is sleeping. I'm talking 1% loss every few hours, even with wifi enabled 24/7. If you are getting much higher drain than that, I'd suspect that you have an app loaded that is causing the tablet to not go into deep sleep properly.

Try this - load CPU Spy, reset the timers and let the tablet sleep. Check CPU spy after an hour or two of non-use and make sure the tablet is deep-sleeping properly by looking at CPU Spy - it should be in deep sleep for at least 75% of the time while not being used. If less than that, I'd guess that there is an app causing it to stay awake longer than it should while sleeping.... Then comes the hard task of identifying the app that is causing it... Better Battery Stats can possibly help with that....
