Does the hotword detection of google now always on or NFC checked on or LTE vs HSAP+ (while connected to wifi or not) or leaving wifi on even when not connected (like when out and about and not at home) affect the battery in a significant way?
Sorry if this is a stupid question I just wanted to clarify because Ive heard various conflicting things on some of these.
Thanks for any help to this question and if anyone has tested any of these and can give there feedback I'm sure it would be greatly appreciated!
LTE if you don't have a great signal will use significantly more battery then HSPA.
Hot word detection on will use a little battery but should only do so when the screen is on.

All of those things will use more battery. I've turned off NFC and hotword detection because I don't really use them. To be honest, I still couldn't tell you if it makes a significant difference, but I'm happy with battery life.
Location settings off, NFC Off, LTE off when not needed, connect to wifi whenever possible, Lux auto brightness app, Battery doctor app, and install a custom kernel. That should help you out a lot with battery life.
NFC and hotword detection make such a negligible effect on battery life.

I want location settings on with google now I dont want to cripple my phone completely or have to be switching things on and off constantly. But I will probably be switching off LTE for HSPA cause I seem to be getting a better signal and NFC off cause I dont really use it. I already have franco installed which I know will only improve in time!
How about Lux is it a low power process running in the background and do the savings outweigh that? and do you have the free or premium version?

So, it seems the default policy for wifi on this device is never to disconnect itself to save power. The Vibrant defaulted to whenever the screen was off. That makes the default wifi policy between these two devices vastly different. In fact, there isn't even an option on this phone to disconnect from wifi when the screen is shut down. I wonder how this will affect battery life. I may think twice about enabling wifi.
The first thing I did after connecting it to my wifi was go to the wifi advanced settings and set the sleep policy to never. I'm glad it was already off by default. It shows that someone at HTC paid attention to that small detail and how it affected battery life. It greatly helps your battery life in my experience (with the Vibrant), since it's not constantly connecting and disconnecting from wifi which apparently uses more power.

Really? How would that *improve* battery life? I would have it to *detract* from battery life. If I'm at home basking in my wireless network, why would I rather have the connection permanent than to have it disconnected when the screen shuts off as it does by default with the Vibrant? If what you say is true, then setting the timeout from the 15 minutes timeout, as I have it now, to full time connection (never timeouts), will actually save on battery? To me, that flies in the face of reason, but then again, stranger things I've come across.
Just hoping for a reply to the above, and perhaps someone can explain why having wifi never time-out even when the screen is off can lead to better battery life?
think about it. having to connect and reconnect everytime you turn on your screen is bound to eat up. if your screen is off its not sucking in massive amounts of data so the battery drain is at a min

Well, it's certainly not intuitive, and I am thinking about it, hence the post. In order to maintain an active wifi connection, there has to be continual pinging back and forth even with no active data connections from the device. Now, we all know that there *is* a lot of data being exchanged when the screen is off - whether it be syncing accounts, retrieving news items, emails, etc. This would all be taking place over a wifi connection by default. It is also my understanding that using your wifi radio consumes more power than your UMTS radio does. However, I'm not entirely sure of that last point.
Isn't it far more intuitive to believe (whether factual or not) that having the wifi radio powered on unnecessarily while in your pocket would consume more power than having it turn off? Even the seasoned users over in the Vibrant forums all recommend setting the wifi to turn off when the screen shuts off, which is a setting not available on the MT4G.
I'd like to believe that how HTC sets the default wifi behavior conserves power, but it sort of flies in the face of reason. I'm also of the belief that the device is set by default the way it is so that callers who use Wifi Calling can always be reached while at home on their wifi network. But, having such a wifi connection setting is actually eating up your battery life if you don't need wifi calling.
Wifi used less power that edge/g3/4g. Having it constantly on wifi with improve your battery life just because when wifi is enabled it shuts off cellular data.

When i enable the GPS toggle on my phone,
Is it really work always ? Do i really need to toggle it off when i don't use it?
Or
It not really active, just ready to be active when needed...
So if it like that i don't really need to toggle it off always.
You see, i think its not like WIFI and Bluetooth that really active when they are on.
Because when you really use GPS you see it at the notification bar ..
Hope you understand what i want to know ..
Get battery snap from the market then run a test over time. If it doesn't affect battery life I tend to not worry...

From what I've heard and read it seems that the GPS really won't drain battery unless an App is using it. So if you aren't in Navigation or Maps or something that wants to use the GPS then the idea is that it won't drain your battery.
I'm not 100% certain, this is just what I've read, and to some extent experienced.
It really drain my battery when its enable.
I switched it off, but now I'm worried that when i will lost my phone i can't track it down with GPS location... (loockout secuirty app)
Any advice ?

If your connected to wifi and using it, are you gonna get better battery life VS being connected to either 3g or 4g/hspa+?
and Why if so?
Shoot im sorry, this shouldnt be in this forum. I thought I was in the general questions forums. MY bad people. Please move mods.

This is the General forum. To answer your question, Yes it would use less battery on WiFi. On a data connection the signal is not a constant and the phone is always looking for a stronger signal.
Thanks, thats what I thought. And ive noticed that connected to wifi my battery lasts a lot longer.

yes. And 4g eats your battery.
When I am only using the phone for data, I use WiFi when available. I turn on airplane mode then activate WiFi.
I don't know about that... when I'm on wifi my battery drains like a mofo. Weapon 3.0 ICS theme faux 1.3 kernel.
On every ROM and Kernel I've tried, Wi-Fi uses much, much less battery than 4G. I haven't tried any of the toggles / battery saving apps though so I'm not sure what effect those might have.

Do you disable data when you use wifi?

He shouldn't have to. If he's draining faster on WiFi then something is screwy with his setup.
On stock, cyanogenmod 7.1, and cyanogenmod 7.1 with various other kernels I've experienced increased battery drain with wi-fi on and connected with the phone sitting at home the entire day. Turn off wi-fi and let it just use the data connection to T-Mobile and I get drastically increased battery times. I'm assuming those of you who get better battery with wi-fi on are in extremely bad signal areas. Also, if you're on cyanogenmod have you turned off the auto wi-fi disconnect when sleeping feature? If you haven't then your battery life when sleeping should be the same as that of wi-fi turned off.
Wi-fi should always be priority if your in range.
Well my personal experience has been that wi-fi eats up battery like crazy. Same thing happens to the other smartphone users I know around here so I was surprised to see that people get better battery times with wi-fi on. Are you guys completely turning off your cellular radio? I don't like the quality and slight delay of wi-fi calling so my cellular radio stays on when I have wi-fi on.
I don't usually notice much difference between wifi and 3g battery drain here (no 4G for tmo here).
As someone already posted, my drain is worst when 3g signal is poor, like when I'm at work and the metal building interferes with everything.
Have you tried checking logs while connected to wifi to see if maybe some app or service goes crazy?
Nothing fishy going on when wi-fi is on. I get about 10-14 hours on battery with wi-fi on and next to no use of the phone vs somewhere around 20+ hours with wi-fi off and similar extremely light use. I keep meaning to do some more standardized testing where I literally don't touch the phone but life gets in the way and I have to make/answer a call or txt or whatever so I can't nail down any hard numbers. Typical experience on a slow day for me is that if I forget my wi-fi is on, my battery will be somewhere in the 3-5% range when I'm getting ready for bed while if I hadn't left it on, I can go to sleep and wake up and it'll still be hanging in there.

That's true, I've always believed that Wifi eats battery faster because someone(don't remember who) always told me that Wifi uses more battery because it processes data faster, but I always noticed that when I used 4g, it drains a lot faster.
I always blamed it on the ROM, but I can see that it's not the ROM's fault.
I was just wondering this because my battery seems to go a bit too fast.
I am convinced there are things I can do to limit this drain somewhat.
I already manually change brightness.
Also the wireless charger I use makes the battery hot sometimes. (maybe related)

You'd be better served to adjust your location to battery saving mode and set your location reporting to OFF before simply turning off Google Now.
Give those a shot first and monitor your battery life for any increase.

It did a lot for me and since I really didn't use it, I turned it off.

If you turn those off, what's the point of Google Now? Might as well turn it off, right?
I will try both, but I think did turn off the GPS thing already.

Turning off location reporting and adjusting your location mode doesn't mean you have to turn off Google Now. You can still use the feature just fine w/o those extra battery draining options.
Google Now itself doesn't drain much battery but the types of cards you have it pull up for you certainly can. Weather updates will wake your phone, as will location based cards.
I use mine with Locations off just for sports updates, search recommendations and reminder support. It will never wake my phone and battery drain is minimal.
I'm using Cataclysm, ART and Franco, and I'm tempted to try out Cataclysm's Smart Radio feature to extend my battery life. However, I've read a handful of accounts that seem to indicate Smart Radio can actually hurt battery life.
Should I turn it on? What should I know before doing so?

You aren't going to blow your phone up if you turn it on. There are too many different factors that affect battery life. It's most likely case dependent. My main issue with that feature is when tethering. When the screen would go off, it'd switch to 2G and that's no good. I prefer the Xposed module Intelli3G as it has an option to disable when the Wifi AP is on, as well as more advanced options vs Smart Radio.
Long story short, try it. If it doesn't work well, or affect battery life in a good way, then just disable and reboot. Shouldn't be any lingering issues.

I use the smart radio in gravity box. I can tell you that is does save battery life but take this with a grain of salt. It all depends how often you unlock your phone and it switches the network, the usage, and a variety of other factors. Where I think it saves the most battery is when I am not using it and it stays on 2g/3g versus being on LTE all the time (maybe not having a great signal or searching for one etc). I hope you understand what I am trying to say.
