Enable Battery Saver with NFC? - Moto X Q&A

Anyone know of a way to enable Battery Saver mode via NFC? I know it's easy enough to go into the settings and enable it manually but just thought it would be cool if I could just tap an NFC tag on my nightstand before I go to sleep.

As explained on your AC thread you need to read up on battery saver, as it does not do what you think it does. Enabling battery saver in settings turns on savings from 15-0% by shutting down background data. Has no effect above 15%. Chris

You're right. I read in one article that you could enable it at higher percentages but that was wrong. My bad.

[Q] Does wifi turn off during sleeping mode?

Hi to everyone. I forgat to turn my wifi off during my working hours. In the nd of my shift, i check my battery and it was proximately %5 left and even i didnt use the phone during my shift. it was %50 or something before starting. Does wifi still work even on the sleeping mode?
Thanks guys
no it stays on unless you set up the power saving mode i use custom settings so that wifi etc will turn off at 40% battery
wi-fi is a big battery drainer. Always have it off if you don't need it. Same with gps, data, and auto-sync for various accounts
Try using juice defender. I think the free version always you to enable wifi control (after your phone goes into sleep mode it should turn off the wifi until you wake it up)

juice defender is in itself a battery drainer. don't use those "battery saver" apps. they're all bs. just get in a habit of turning off connections manually when you don't need them.
Are you aware of the setting: wifi settings/advanced/wifi sleep policy and set it to sleep when screen turns off?

Thanks I didn't know about that setting, but my question is once wifi turns off mobile data kicks in. Which drains battery more? Wifi or mobile data?

They both drain battery equally as much. Mobile data shouldn't kick in unless you have it toggled on.

Use Green Power to automatically disable wifi and data when the phone goes into stand by. There are lots of settings like enabling wifi at certain intervals to sync email/whatsapp/other push services.
On GB for me it's the difference between losing 25% battery overnight without it and losing only 3% when it's enabled and that's with sync every hour.
It seems that on any ICS rom wifi doesn't use any juice even when enabled in standby. Because of the kernel bug in the leaks I'm now on the official CM9 rom and after almost 9 hours with wifi turned on I only lost 4%, on every other ICS rom I tried I get the same results.

I tried juice defender ultimate but connection was on and off and time to time it took ridiculous amount of time to get the connection back :/ also I don't know why with juice defender I noticed sluggish performance phone, after uninstalling everything was much more snappy.
I have wifi on all the time and I only lose about 2-3% over night on stock, I guess it's fine the way it is for me without using all those battery "saver" apps.

I disagree. I definitely get power savings with JD compared to without it. Auto-disabling WiFi saved loads of power for a start, and my overnight drain has gone from 3-5%, to approx 1% with JD running. I'm not saying all batt saver apps are worth using, but JD works for me.
Its a lot easier to have a well-behaved app that DOESN'T use a lot of power itself manage your connection toggling rather than having to remember to do it yourself.

Wrong. WiFi uses more power. Its a separate transmitter being driven by the battery, whereas as mobile data will use the existing transmitter (phone) that's already on, but obviously drive it a little harder than if it was all off.

[Q] Battery drain from wifi on CM9?

Recently, I switched from Oat's Light n' Tasty to CM9 nightlies (currently on 20121202) which I flashed with CWM. I have noticed that the battery drains significantly faster with CM9 when the device is asleep. Looking at better battery stats I found that ath6kl_wow seems to be the culprit, which was reinforced with GSam which reported that 89% of the battery was consumed by wifi. Any ideas of what may be the problem or how to resolve the battery drain?
Thanks.
Have you gone into the advanced WiFi settings and set it to sleep when the screen is off?
Additionally you could try increasing the WiFi scan interval in the build.prop

I want to be able to get notifications from the device, so ideally i wouldn't want the wifi off when the screen is off. I haven't edited the wifi scan interval yet, any recommendations on a time i should enter into build.prop?
You could try 180, but if you are always connected it won't make a difference.

Battery issues

So I've been having some massive drain since I've flashed slim bean. I ran battery calibration, that didn't seen to help. So I checked my battery settings and this is what I saw
Sent from my SGH-T679 using xda app-developers app
What I can see is wifi on battery drains from wifi alarm on polls for times. Also Facebook apparently has instant notifications on and avast looks like it is checking on Facebook. That means 2 active apps running on wifi with clock running so system isn't going to sleep. Try limiting Facebook checks and do manual checks for between times that it checks. Smartwifi toggle app is also good as if you leave wifi area wifi shuts down saving battery. Alarm well not much goes on there but will wake device to make sure your alarm is accurate.
As a side note I am down to about 1% drain per hour on slimbean overclocked to 1612

Phone Runs at 51Mhz while charging

after update to V20a Euro Open, when i put to charge my phone at nights, it's never get fully charge, i use CPU Spy and notice that the phone, runs at 51Mhz all night, i installed BetterBatteryStats, but i don't see none application running overnight, how can i do to know what is using CPU at that speed? obviously the phone doesn't enter to deep sleep mode, but when is not charging, the phone enter in deep sleep mode normally
When it is charging it can`t enter in deep sleep because its working on 51Mhz(charger produces that frequency..)
Are you telling me that is normal? Even when the battery only reach about 95% of fully charge? When i had v20a leak that behavior never happens

How do you mean the batt only reaches 95%? You can`t fully charge your battery?
That's right, rhe phone runs all night at 51Mhz

Yeah, but with the phone running at 51Mhz, it should be able to charge completely.
Even running at a higher speed, i.e. browsing the web, playing some lighter games. It might not be the healthiest thing for your battery, but it shouldn't impede a full charge.

well but that is the problem i'm trying to find a way to know what process are running when the phone is charging and i can't find an app that show me that, the only thing that calls my attention was Audiut2 Wakelock i thought that is the problem, but i was reading and some foros says that wakelock is normal when you use some sounds like the screens sounds or lock or unlock sounds, or something like that
You have to do a dumpfile with BBS. Allow all root access and thick all options in advances settings. Leave the phone over night and in the morning do a dumpfile..

Other stats, partial wakelocks stats, and kernel wakelocks stats are automatically checked. Go into advanced settigns,there everything is checked except "private storage" and "enable while charging". Charge your phone,leave it over night,in the morning do a file dump. you have a share icon at the top,click it and then share as text dumpfile..And then you post it on XDA!

[Q] Wi-Fi on during sleep

Hi,
I changed the setting to turn off Wi-Fi when the tablet is in sleep mode. However, when I check my battery usage, it indicates that Wi-Fi is on almost 100% of the time.
Can I do anything to fix this?
Try better battery stats available here at XDA. Although it's designed to help you find out what's using your battery, the info the app produces will show you what programs are running the most. Odds are one of those uses wifi and that's what's keeping it on during sleep. Just remember that you'll need to be on battery and not plugged in or docked to gather the app usage info.
Sent from my Nexus 7 using Xparent Purple Tapatalk 2
Definitely an app keeping wi-fi awake. I have mine set to never turn off during sleep and I only lose 3-4% overnight. Wakelock Detector is another app that can identify which apps are keeping wi-fi active.
Thanks, I'll try to see if these apps can diagnose the problem.
