I have wifi set to NEVER sleep. But no matter what I do, the phone keeps turning off wifi every time the screen is off for more than a minute. Why? I tried doing a hard reset, it didn't fix the issue. I saved the Advanced Settings after I changed the sleep policy.

1. check ur battery profile
2. check to see if any other app is doing this. i had 'super power' on mine doing this for me; got this app when I restored my data from captivate to this phone. I had to disable the option in super power, and since then its not doing this.
Huh. I'll try performance mode.
But that still doesn't explain why it would turn off the phone's wifi capabilities completely after a certain time.
And the info for the battery profile doesn't mention wifi.
Whoops. posted twice accidentally
i've had wifi sleep issues rom day one with a wpa2 enterprise network. It refuses to join after the first time, and eventually sets the network to disabled. I'm far from impressed. I wish a hotfix for all 2.2 installs would be released
Well, that was it. The battery profile was the problem. Thanks.
Now if only I could figure out why the phone absolutely refuses to download apps from the market faster than around 200 kb/s, on 3G, 4G or on wifi.
Even on 'performance mode' I am facing this issue. It just keeps disconnecting from wifi. Even if I turn it off and on from widget it doesn't connect. I need to go through settings and to wifi, and then it says "connecting..." and connects.
Ok today I got massive battery drain, nearly empty after 8 hours.
The culprits are
Datacounterwidget (26% - used to keep track of amount of data I use each month)
WiFi sharing (18% - what is this? I dont think Ive used this before)
Openwatch (14% - bluetooth connection app to my bluetooth watch - didnt use it today)
Display (14%)
Android System (9%)
These numbers seem pretty strange to me, usually it will be screen about 45% android system about 30% and the rest split over the other things.
I have noticed wifi sharing pop up before and take a sizeable chunk out of the battery and I am thinking that may be the cause of the massive battery drain. Datacounter widget has never been up this high before and I think is just a by product of the wifi sharing.
Anyone know how I can prevent this from running? Or what it is?
Thanks
WiFi sharing is that not letting others use your WiFi connection as a free access point .

That's what it sounds like to me but I haven't set that up :S
Can't even see an option for it (well I see options for wifi hotspots but this and tethering are disabled)

My observation is that WiFi sharing and WiFi sharing manager will start in the background as soon as a WiFi connection has been established. They remain in the background even after you've turned off the WiFi and continue draining the battery. I've formed the habit of manually stopping both WiFi sharing and WiFi sharing manager every time I finished using the WiFi and they no longer appear in the battery-eater list. I've been wondering whether this could be automated and even better, when the WiFi-sharing battery drain will be fixed.
I have turned off the positioning by network option and now wifi sharing dosent appear on the list anymore. ... so i think it has something to do whit this

use Titanium Backup and "Freeze" Wifi Sharing... bam! not eating battery anymore. plus if I need it I can just unfreeze it.
Hello, everybody. Newb here (only have had the HTC Evo View 4G for a couple of days now). I have a question about the battery and screen. Is it regular for the screen to use up about ~60 percent of the battery? (According the usage stats). I find that the screen is bright, even on the lowest setting.
Also, I have a question about the battery. It seems to be draining a little quick (I am using lowest brightness and WiFi only). Could some people share how long their battery usually lasts for regular usage? I don't think it's a hardware issue. Like I've said, I've only had it for 2 days, so I don't know if I still need to wait a little.
Thanks!
The screen is one of the biggest battery drainers (if not the biggest) on tablets. So if you are using the tablet a lot, and the screen is on for long periods of time, then 60% seems normal. I don't have my Flyer with me right now to check what my % for screen is.
Battery drain is going to depend a bunch on how much you are using your View, and for what. With moderate usage, I can get around 2 days on a charge. I'd say that is about average for me. But if you are downloading big files and gaming, and/or have the screen on a lot, it can be significantly less.

Okay, that makes sense. The battery life seems to be getting better. One more question. I want WiFi to turn off after a certain amount of time once the screen timeouts. Is there any way to do this in the settings or with an app? The settings (official 3.2) has a WiFi timeout policy that gives three options:
Switch from WiFi to mobile data when screen is off
Never switch WiFi off
Never switch WiFi off when plugged in
I live in Canada and don't have a plan. Would using the first option drain more battery because it is looking for a connection? Or should I use the third option?
Thanks again.
Hmm, not sure. I have the WiFi only version of the Flyer, and on mine the first choice is just "When screen turns off". The first choice on your View is weird. Mobile data always uses more power than WiFi, if both are available. I don't see why you would ever want that.
BTW, I'm at home and have access to my Flyer now. Battery usage for screen is 52% for me. So I'd say 60% you mentioned is pretty normal.
You should also take into account, unless you've taken steps to turn it off/remove it, Cell standby might also be causing your battery life to take a hit. Since the View is set up to also be able to receive text messages, out of the box it's constantly trying to connect to Sprint's cellular network, even if you have mobile data turned off. This thread discusses ways to deal with it. Cell standby used to be one of the biggest users of my battery. Now, it's no longer a problem and I've seen a major increase in battery life.
As for the WiFi issue, the first choice in the settings actually says "When screen turns off (uses more mobile data)." That doesn't mean that it automatically switches mobile data on if you've turned it off in the settings by selecting that option. It's worded that way because the View is designed to be used on Sprint's network, so under normal circumstances it is assumed that if you turn WiFi off, you'll have a data plan and automatically connect to the mobile data network. If you don't have an account with mobile data from Sprint, and you've turned off mobile data in the settings, it won't be an issue because you have nothing to connect to.

That makes much more sense.
Okay, thanks everybody. I really appreciate it. With heavy usage (basically using it all the time) I'd get about 6 hours and 10 minutes. Is that normal for everybody else?
Also, I have a couple of more questions, if you guys don't mind.
First of all, could rooting my device boost my battery life? Would it give me more access to settings like screen brightness?
And, do apps running in the background use battery life or are they 'frozen' until active? This sort of leads me into my next question. Is having 400-500MB of RAM always being used normal? Is the OS using all of it?
And I notice that when I put my tablet in airplane mode (to kill the 4G radio) I lose access to Bluetooth. Is this normal and will turning off airplane mode for a minute be a battery drain?
Thanks again, guys.

Answers:
Rooting won't necessarily boost battery life, but does give you ways to access more system items if you want using apps that take advantage of root.
Android attempts to keep non-rumming apps in memory so that it can load them faster in the future (Ram is much faster than SD memory). 80% Ram full is typical.
Airplane mode turns off all radios, BT, Wifi, GPS, 3g.
There are apps in the market that can turn various things on / off based on your environment / time / conditions

You don't need root access to adjust screen brightness. Settings -> Screen -> Brightness.

Airplane mode turns off all radios initially, but then you can turn almost all of them right back on (except for the cellular radios). I run mine in airplane mode all the time to keep the cellular radio completely inactive, but I still use WiFi, GPS, and Bluetooth when I need/want them, and they all work great. Are you running Gingerbread or Honeycomb? I do seem to remember some mentions of not being able to use Bluetooth in airplane mode on Gingerbread. It works perfectly fine on Honeycomb.
And you can turn off the 4G radio and all data service without turning on airplane mode (Settings -> Wireless & networks -> Mobile network). Doing this turns off all radios that receive data from the cellular network, but it doesn't turn all cellular functions off since the View is also set up to receive text messages. That's what airplane mode or any of these options address.
What I meant by adjusting the screen brightness was being able to control its range more than I can right now (I feel that even the lowest setting can be too much). But it seems that rooting/installing a custom ROM wouldn't do too much for the battery.
But my issue with airplane mode is that I can't turn on Bluetooth with it (Bluetooth is 'grayed out'). I am running official Honeycomb.

Did you try tapping on the box for Bluetooth in the settings even though it looks like you can't, and did you try using a widget to turn it on? I'm using stock OTA Honeycomb, and Bluetooth works perfectly fine for me while in airplane mode. I can turn it on in the settings (the box does look a little "grayed out," but you can still select it) or via a homescreen widget. If you can't turn it on with either of those, then it would seem that you've got some other type of problem. It works fine for me. I just tested it out again.

I just tried it. It seems to not be working for me, but it doesn't seem like a glitch but something built into the OS (I tried with a widget and it did a little 'no' animation). It's alright, I rarely use Bluetooth anyway.
Thanks for all of your help (plus everybody else, too)!

I'd venture to say it's not something built into the OS. If it is built into the OS, then there's a glitch that allows me to use it under the same circumstances, and glitches rarely enable functionality. They almost always cause a device to lose functionality like you're experiencing. I'd be curious to know if anyone else is having the same issue you're having.
Last time I have ran battery test on my Flyer I ran it for almost 11 days on one charge. Yeap, 11 days. I mostly used Flyer as a notepad, checked orders on website couple of times a day, read emails. One day I played a game for about 20 minutes. At the end I set up and tested Plex and Google Music. I stopped the test at 11% charge. Overall screen was on for a bit over 4 hours (40%). Wi-fi on for 16 hours (only 4% ??) according to stats. That's pretty much it. Tablet idle 43%. Fairly light usage, but I mostly was testing how much of useable time I can get out of it. 11 days is a pleasing result.
Please explain me, I just dont understand the settings. What's the difference between 3 options: always, only when plugged in, never? I see that regardless of either option WIFI stays on during sleep. It is clearly seen from statistics. So what's the use of it?
Come on people, I can't believe nobody cares. Did I ask something stupid?

well perhaps no one have seen your post.
anyway, i just saw that feature a while ago, and i think what it means is:
when your phone screen turns off (your phone is asleep because you're not using it), wifi connection gets disconnected -- to conserve battery.
the options are:
always (default) - will keep wifi connection turned on, no matter what
only wen plugged in - well, wifi connection will keep on ONLY when the device is plugged in.
never (increases data usage) - as soon as the device sleeps, it will disconnect from wifi, and possibly conneted to data network, hence the warning.

1. Always on even if screen is off (DS WiFi ON)
2. Only when charging WiFi is still on (DS WiFi ON while connected to USB or AC charger and DS WiFi OFF when disconnected from external power source)
3. Never online while in deep sleep - disconnecting WiFi in Deep Sleep (DS WiFi OFF)

Dear friends. Thank you for your replies but I suspect you didn't get the point. Again, regardless of one of these three settings WiFi is still ON during sleep. Try to set it to "never" (given that global WiFi switch is on of course, thus it should go to sleep along with device), disable your mobile data and run Skype for example. After your phone has fallen asleep you still online in Skype and available to receive calls. You're still on WIFI! It doesn't switch off when phone sleeps!
I know this is an old thread but did you manage to figure this out? This has recently been bugging me too. Thanks!
If wifi doesn't disconnect when it's set to "never", maybe your phone doesn't go to deep sleep properly.
It'd be good if we could read somewhere what this "deep sleep" really is..

I agree! phone may not go in deep sleep even after switching off screen.
And also also this question is really not stupid, but I say google is stupid, that he assume we have a data plan active always. I have wifi at home and office, so am not activating data plan. So I was having the same question/confusion about this option!
Keep wifi on during sleep -> never, so how come it increase data usage?? data means not data transferred through wifi but sim card internet!! Ha ha ha..
Google should clarify it that when phone is connected to wifi, it will not use sim card internet, but if wifi is off and mobile data plan is active, android will use sim card internet.
Also I'd like to add that wifi signal itself is not eating much memory, but in most of case, fb/gmail/google+/twitter etc which are always internet crazy (hungry) will not let your phone asleep. and they eat memory. if wifi is off then we can have two option, 3G and 2G phone internet. 3G signals eat more battery, and 2G internet use more battery because of slow speed.
Background activities option came in picture with invention of smart phone, but always misused by google+ and facebook!!!!
I always hate fb android app, it is too slow in 2G and surfing site in Opera mini is way too fast and handy, anyway that was my taste.
Take a look at green power app as this handles 3g/WiFi connectivity very well. Much better than juice defender

So whenever I left wifi area or turn off the wifi soon after the mobile data gets automatically turned off, the icon of it shows not just for specific app.
Even when I turn off the data saver, it doesnt help.
This is very bothersome as I will miss alot of stuff.

Anyone experiencing or heard such problem with Huawei Phone? Need help.
Are you talking about missing notifications?
If you enable Developer Options (settings/system/about phone...then press build number 5 times) then in Developer Options there is an option you can tick to always keep mobile data active. I use it for faster network switching and it doesn't have much of an impact on data use or battery drain.
But if you are talking about missing notifications that might not solve your problem.
You want to remove any apps that need timely notifications from battery optomization in the power settings. Make sure after you choose to manually manage the apps that they are allowed to run at startup and remain running in the background. (All 3 options should be allowed).
If that doesn't solve your problem then you might also need to remove Google Play Services from automatic power management since that service is normally responsible for syncing Android phones.
Huawei has more aggressive power management than most Android phones which provides great battery life but also annoys many people because they can miss important notifications.

No, the entire data just cut off after leaving wifi even thou the mobile data was on prior to leaving the wifi spots or just turning off the wifi. Does that make sense? I have had so many different phone this has never happend to me. I even turn off the data saver mode too.

If I turn that option on in dev mode "always leave the mobile data on" even when the wifi is on (even when wlan is active) does that mean it may sometimes suck up my mobile data while wifi is on, i dont want that.

Ok after tons of digging found the problem. a function i have never seen on previous phones.
basically you go to mobile data setting and go to more and then (wlan/mobile switcher) go in there and thats where the problem is.
I now select switch to mobile data.

I don't see that setting. Does this fix the fact that when you use hotpsot the phone is incapable of any data? I can't use hotspot at the same time as data on the phone itself.
