[Q] Wifi, or 4G?

I just got a sensation and I absolutely love it! I just have some questions.
First off, I have a great connection with My Home Wifi and T-Mobiles 4g network, so what should I be connected to at my house? What saves the most battery?
If it is wifi, how do I disable the Wifi Calling Notification that just tells me "Wifi Calling Ready" Like I get it.. I don't need the ugly notification reminding me. I can't find out how to disable the notification, without disabling my calling....
Thanks!

WiFi, would be better. I don't know the second question, I don't have a sensation.

Uh, yeah you can. Turn it off.

Turn off wireless LAN unless you are using it. But for web browsing, cellular data provides better battery life than using WiFi.

WiFi is easier on the battery and in some cases faster than your mobile network:

Dude, battery life shouldn't be your main concern when it comes to WiFi vs. mobile data. You should be using WiFi whenever possible so as to save as much of your allotment of data as possible. As pointed out, WiFi can be faster than mobile data. There's no reason to be using mobile data when WiFi is available unless your battery is extremely low (which shouldn't be an issue when you are at your house).

The JuiceDefender app is good here also, as you can configure it to turn on your wifi radio when you are at a known location such as your home (it learns and knows where you are based on which cell towers you are connected to), the wifi then gets turned off when you are out and about.

Also, it depends on the strength of your wifi - if you have bad wifi signal in some you might be better off with using your 4g network so that you don't drain your battery by having your wifi radio on all the time

wifi definitely saves the battery at least in my case. keeping phone on tmous signals is a big battery drain. also i will recommend using juice defender to prolong your battery life even more.

Wifi saves battery and data. No one likes being throttled lol

Best Battery Saver App Ever!!

Ok so i have tried many battery saver apps and have come to the conclusion that most of them are a joke. Until i tried BatteryXL. With a bit of setup this app has give me over 20 hours of life with use. I am talking about web surfing, texting, gaming, calls and some picture taking. I use my phone a lot and it just would not make it half the day. I even tried an extended battery. But even that sucked. Juice defender isn't bad if you buy the pro version, but BatteryXL is free. There have been a few glitches , as it is still in beta, but they are very minor and didn't effect its usage. So if anyone is looking for an app to help with battery life try it and see how it works for you. I am no way affiliated with the creators of this app. I am just a big fan of it and i know how many evo user complain about battery life. Also if you want to know i am using Sinister rom version 7 and anthrax kernel 009. The rom and kernel you use will affect how much this app helps.
Again i have no affiliation with the make of this app so don't ask me if you have issues. Submit then to the maker.
EDIT: If you don't have an intelligent thing to say, then do the world a favor and keep your mouth shut. The air is polluted enough as it is

Guys, please do not make me close this thread. Stay on its original purpose instead of attacking each other.
Consider this a warning. There is no point on either use so much exclamations marks, replying in such way to it and then attacking back in the same way.....
I am telling you the nicest way, stay on topic.
YOU ARE WARNED!

Thank you D.O.C. I just wanted to inform others about this app because i know battery issue is a big problem for most of us Evo users. And i am sorry for the off topic spat

BatteryXL has saved my battery.. i've been under 50% for over 4 hours already and still have 39%..
thanks for sharing...

Interesting

I switched over to an ICS rom and it still is getting me around 15 hrs or so. I love this app.

Been using it since the 28th and been able to go a full work day without a charge....on my normal high use day....thanks

I bought jd pro a while back but this one seems so much easier to set up. We shall see how it goes.

One thing I hate about this app is it shuts down my 3g when I programed it to shutdown everything else lol
Sent from my PC36100 using xda premium

Yea I've tried using this app but it just doesn't work like juice defender... this app doesn't auto sync 3rd party email apps or twitcaster... juice defender makes it possible to sync specific apps during a specific time frame to resync information while the screen is off.. I haven't seen this app (battery XL) do that at all...

Yeah, I'm a bit leery of it myself, after reading all sorts of comments about people having issues getting various radios to come back on. Would like to see more feedback about it, though.
Sent from my PC36100 using xda premium

Only issue I have had is every now and then it won't turn my mobile data back on. I will take that since I can get almost 20 hours of use every day. I will post a screen shot of it later today to prove it.

Yeah, I enjoyed this app until I too had problems with it randomly turning off my data, other than that it is great at saving battery life.

Here is a screen shot of my battery status s of right now. 12 hours and still over 60%. Not as much use today but still, about 1 hour of web and games, and lots of texts.

What does this app do exactly..? In what ways does it save battery... does it lower cpu usage or does it disconnect wireless connections when not in use or what..?
Sent from my SPH-D700 using XDA App

Like most battery savers out there it controls connections and other features. But unlike most others this one actually does help get you more battery life. Before using this app i would only get about 12 hours total before I needed to charge. Now as you can see from above I get about double that.

@OP.
prior to using this app, were you one of those (like me) who always turn off unnecessary radios and services manually? Cuz I've always done that, and if this app makes an effect beyond that, I might be interested.
But I prefer to do it manually, myself (not to mention, due to OCD, I would always turn off radios manually). Are you not in that camp?
Sent from my PC36100 using xda premium

No. I can't say I am. I never remember to turn them off so this app is great for me. It does have some other cool stuff. Check it out is all I can say. It is free. So if you don't like it you aren't out anything.

Simply put, the app sucks. Sucks bad. The concept is good, but the app, it sucks

works fine on HTC one, somewhat its like the HTC power saver but better .

think probably the best battery saver out there at the momonet

Why is my battery dying so fast?

It seems like my battery is draining very quickly. Android is the highest on my battery list. I don't have anything weird installed or syncing and my screen is set to 50% brightness. Any ideas?

If you have root access you can install Better Battery Stats (Free here: http://goo.gl/EjdB8) and choose partial wakelocks since unplugged. That will tell you what's keeping your phone from deep sleep.

Nothing is standing out in partial wake locks. Every bar is pretty much empty. And that app isn't free anymore according to that post.

Op, are you rooted? I noticed my battery goes a little quicker since I rooted and flashed cm10. I also noticed you are on 3g, did you disable 4g, is 4G available in your area? Maybe the phone constantly searching for 4G is draining. Not sure how that would show up in battery usage stats though.

Yes I am rooted. I noticed the battery draining faster after I flashed Google Wallet. I am stock rooted though. I turn off NFC when I don't need it, and the app doesn't sync often.
I'm not in a 4G area, but that has never drained my battery before. I can't imagine Wallet would be draining my battery..
I should also note that my brightness is set to full at all times. What's of interest to me is the fact that it isn't draining so much when the screen is on, it's when the screen is off is when it drains the most it seems. I'll leave the phone off for at least 20 minutes and when I turn it back on it'll have lost a few points.
Can't seem to figure it out. Like I said, it seems like I started noticing the battery draining quicker after I installed Google Wallet.

[Q] Screen absolutely killing battery

Hi, so ever since ICS, or at least SCv7 (not sure if it did it stock, I switched right away), my screen has bee completely killing my battery
I still get perfectly fine life with the screen off, but it just drops right down with it on even not doing anything to heavy. Definitely a problem not normal.
Anyone have any ideas? Is this happening to anyone else?
P.S. Thanks for the new Q and A section by the way.

What are your screen settings at (levels, auto on/off, etc)? Screen is by far the biggest drain on battery. Check my Battery Guide, last Page for an app mentioned to lower brightness more than the stock settings will allow for- maybe that would help in certain instances. I haven't tried it myself, but will be doing so over the weekend, and if beneficial I will update the OP with it.
My SGS3 is the same as my A2 being that the screen gobbled up battery like crazy. So, I suppose you're not alone, at least with what I've experienced.
Not sure if any of this is helpful, but thought I'd share my thoughts...

I keep it on auto or low all the time. this is definitely a real problem, because it was nowhere near as bad on GB. now I know they fixed the cell standby issue, but I can literally see the battery go right on down when I turn it on. 3-4 hours on would kill it.

Maybe try with auto off for a while, see if you notice any difference.

Turn auto off and get a widget to adjust yourself. Read an article one time how on Android system auto brightness is more harm than good.

Looking at your battery's discharge rate graph, looks pretty normal. There's no drastic drops in battery, it's fairly linear in discharge, and even if the screen is using most of that. However, there could be other culprits. What about sync, or haptic, or any of the other things I outlined in my guide? WiFi is off, from what I saw, but might not just be the screen. Have you tried editing build prop for "deeper" deep sleep or edits to other things? I'm going to update my OP with a few more things I thought of for improving overall battery life this weekend. Maybe some of the new ones will help...

I'm sure that the display is eatin more than GB ....
i didn't see display going >50% in GB ..... now on ICS its like always >=70%
i have 2nd system as MIUI from "rdavisct" when i switch to it & come back to ICS
then my battery calibration scrambles ... i did switchin yesterday & it showed me
30% far early than expected

Same problem here..my screen draining 57%

Why don't you try the app betterbatterystats it's here in xda:
http://forum.xda-developers.com/showthread.php?p=15869868
This may help to see the real problem of the fast battery drain you said, also you can install the app rootDim from the playstore to custom your screen brightness.
I hope this helps.

If YOU are noticing degraded battery life after kitkat update, post here!

Are you noticing worse battery life after doing the kitkat update? I am, and I want to know if you are too.
Post in here, take the poll, and lets figure out how to track down what is going on.
Requirements: Try to post a screenshot of your battery stats, wakelocks (if possible) and how many hours you were getting before on a charge.
Here's my input:

I will get some screens soon and try to track it down but I have been noticing that on days I use my Bluetooth after I turn it off. See a drastic.decrease in battery and my phone gets hot. I was have seen others say there was a Bluetooth wakelock as well and it's very random when it happens

My two main reasons for me rooting are ad blocking and greenify. I just learned that greenify added support for non-root users. I have greenified every app I don't use on a regular basis and am noticing significant difference in battery. The only thing is that after you use a greenified app you have to re-greenify manually.

Greenify and tasker work great, I had tasker auto hibernate all greenified apps upon screen on. Its basically the closest you can get to automation without rooting.
Greenify has saved my battery issues.

More often than not, a factory reset will take care of battery issues after a major OS upgrade. I'm not sure if it's left-over system files or something about the "upgrading" of existing apps during the process, but I've had to do it with both my Galaxy S3 and Nexus 7 2012. Not every upgrade, mind you, but with one or two.

I do notice my system battery monitor jumping around all crazy, this is after a factory reset.

Sent from my LG-D801

Bout the same for me. Only thing I notice is that before my wifi was always running in background according to bbs, no matter what I did to change settings. Not anymore after update.

First cycle on the update I lost 35% or so in a couple hours with little use. I checked battery use and Instagram was the primary hog. Uninstalled and reinstalled the app and getting awesome battery life comparable or better than before the update. Not sure why instagram went crazy but works fine now

The update fixed a serious wakelock issue caused by wifi calling for me. A lot of wakelocks seem to have disappeared with the update for me.
Nothing leaps and bounds, but notice a bit of an improvement for sure.
