Not sure if this is the place to post, but here goes.
Anyone experience the same problems?
My tab: Stock P7510UEKME
Issue list:
1. Wireless sometimes unable to reconnect after hibernation: Only solution - Reboot
2. Randomly unable to unlock after hibernation: Solution - Reboot
3. GUI lags a bit compared to my wife's Ipad
4. Battery drains much faster compared to my wife's Ipad.
5. Random reboots
6. Installing from Market sometimes requires several attempts. It just says "ready to install" but does nothing.
These are not huge problems. But, they are very annoying when they happen.

1. This could be your router- when you hibernate the tab sleeps its wifi. So on your tab change wifi sleep to never. Reason for this is to hold your IP address in the router. When wireless devices ask for internet from the routers, they assign a ' floating ' IP address. So in this case you turn on the tab and the router gives the tab an IP address of 192.168.1.3. ( the router assigns its IP's in sequencial order. So the next one would be 192.168.1.4 and so on. ) but then say you hibernate the tab, the router sees its lost the connection with the tab and deletes that floating IP address it had previously assisnged to the tab. Then say another device wants wifi, the router is going to give it the lowest available IP address, and it might be the one that the tablet was assigned to. So say it does, now your tablet cannot connect because it is looking for the old IP address that it was on. The tablets wont ask for a new ip address, and tries to reconnect with that same IP address, without success.
You can fix this by doing and making a static IP address on the router just for the tablet. But that's more involved and I would check to see if the wifi keep policy is on never.
2. Hmmm how long is this tablet on hibernation? Sounds like you have too much going to or loaded in the bkgd and getting GUI lag...
3. Each pad has its owe inherent lags. Rooting , custom roms and over locking kernel will fix this.
4. Could be a placebo that it seems like it is. I would root and use the calibrate battery app in the market. Also don't leave your screen on full brightness, put it low until you need it. Also you may just be doing that much more than your wife, causing more drain.
5. Custom rom will fix this. Samsung has the whole system all jacked up...
6. I have had this myself, but never fret. Just reboot or delete google account and log back in and that should fix it.

I think these are all known issues.
1. happend twice to me in the ~50 day I have the Tab
2. heard of an "unresponsive to touch" issue after sleep, never happend to me
3. stock launcher is slow compared to eg. ADW EX
4. mainly depends on your settings and the apps you run in the background, especially those who keep the Tab from "sleeping". Mine loses ~2% per 24h with wifi shutting down when the screen is off
5. heard of that issue, never happend to me
6. this is annoying and we are all waiting for an update for the Market app from google

Thanks for replying.
1. No, the wireless issue is not the router. It happens outside of the my home as well. Currently on a business trip, and it happened this morning too.
2. Several hours or overnight, usually.
3. OK
4. I got some more sync activity (emails and such) going on, but other than that, it is pretty much the same. I know Android have had battery issues in the past, maybe they're not quite fixed yet.
5. Custom rom might fix this issue, but I don't want to introduce new problems by using a custom rom. The lesser of two evils, right .
6. OK, but no biggy really.
Again, thanks for your reply. Appreciated.

I had those 3 problems before (all 3 solved with pershoots kernel). Solutions that worked for me before:
1. Enable/disable airplane mode.
2. Once you press the power button (to turn on the screen) wait 5-10s. Then touch the screen to unlock it. I have no idea why, but it worked for me.
3. Check what is using the battery. For me it was 2 apps that used 60% of the battery. Once uninstalled it was all OK.

I have a couple of comments. I have had an iPad2 since it was released, and I got the Galaxy Tab 10.1 (P7510UEKME) a couple of weeks ago. It is rooted to accommodate the "Hulu" Flash library but otherwise unmodified.
It seems to me that there are some interesting tradeoffs here. For what its worth, I have not experienced any of [1], [2], or [5], not even once.
[3] I find both interfaces very responsive and have no issues with either one.
[4] Consumer Reports reported (tested? not sure) battery life and got 11 hours from the iPad and 9 hours from the Tab, browsing the web (wifi). Another review, "Tablet Shootout" from the San Francisco IB Times, was based on a test with both machines playing video with wifi on, and 65% brightness. The Samsung clocked in at 6 hours compared to almost 10 hours for the iPad. This is in line with my experience on both machines. The Samsung does have more pixels to decode - 1280x800 vs iPad 1024x768 - and it takes more power to compute those 33% extra pixels. Or it might just be a code maturity / efficiency thing. But after watching an action movie on the Tab in widescreen 16:9 HD and comparing it to 4:3 letterboxed on the iPad, I was sold on the Tab, even with its shorter battery life. Then again, I don't spend much time on airplanes.
[6] This is a known problem but it still is a major annoyance. I cannot install a new program on the first try, ever. Sometimes I have to try 5 or 6 times. This does not occur with on my Droid 2 running Android 2.2 or Android 2.3. I wonder if other Honeycomb users are having this problem or if it is a Samsung thing - does anyone know?

There is so much I like about the tablet compared to the Ipad. I wouldn't switch at all. I realize that there is no such thing as perfect software, and the Android ecosystem will obviously mature over time. Just hoping for some more native tablet apps (sooner rather than later) and if they could increase the battery life just a little, that would be perfect. I have not had the "install from Market" issue on my Galaxy S2 phone, so I think it is a Honeycomb issue, but not sure.
Thanks for replying.

1. Tried that, didn't help.
2. Will try it. Thanks.
3. I did, and it said Google maps (wth?) and Screen. The screen is set to its default settings and I haven't used Google maps at all on the tablet. Weird. I have "use location" enabled, but I didn't think it actually had to use Google maps to work.

I have a GTab runn Vegan 5.1 and it runs great. The one issue that I have is that my Wifi gets disabled each night when it goes to sleep. When I say "disabled" I do not mean this it disconnect, but rather that something is actually putting it into a "Disabled" state and I must select the connection and choose to enable it.
Does anyone have any thoughts on what could be doing this? I have dug through every setting I can think of and also looked at any apps that might be doing this. I even went so far as to remove all my battery saving apps, but no dice.
Any suggestions?

Have the sleep policy set at never and this does not change anything. From what I understand this setting will disconnect wifi when the device goes to sleep. In my case the connection is not disconnected but rather completely disabled. So it seems that there is some other thing disabling the connection.
So, to give a bit more info here, I have installed wifi keep alive to try and save the connection. This keeps the wifi from being disabled when it is plugged in, but it still gets disabled when it sleeps and is also unplugged. (I.e. on battery and sleeping)
So, I am starting to think that the setting that fixes the problem while pluggedin is settings / applications / development / stay awake. I have this turned on and it seems that with stay awake and the wifi keep alive I am good when plugged in.
So, does anyone have thoughts for a similar setting when on battery power?
I can't help to much with battery power since I almost always have mine plugged in.
It's odd that not helping you, once I made that chance I stopped having my Wifi turn itself off (not sleep, off, and the tablet would need to be reset a lot).
Sorry that wasn't much help.
Having this problem as well. Anyone know how to fix?
If you notice other weird stuff happening in the future you may need to repartition your internal memory. Mine started with similar flubs and progressed to never remembering logins online. I had to login to xda every time I turned my device back on. Keep this in mind, about 30% of people need to reformat.

can you give some info as to how one would go about doing this?
For what its worth, might help to set a fixed IP address. I often got a problem with Wifi not being able to reconnect because it got stuck on "getting an IP address" and failed to do so. I seem to remember it disabled the connexion to that AP after too many tries on my Nexus One.
On my g tablet, I was having what seemed to be the same problem, so I did the same thing and it seems stable since. Granted I didn't toy with it as much as I did on the N1, but I wouldn't be supprised if it were a general Android problem.
Anyways, its free to try.
The wireless uses a lot of power. When the tablet "sleeps", it should go into a power saving mode. Disabling the wireless is a feature, not a bug.
Either way how can I keep the wifi signal on so when i wake my g tab up the wifi is ready to go and does not have to reconnect?
anyone have anything to help with this?
I am not sure, but it seems to me that downloaded apps can play with wifi this way, as long as they have rights to "access internet, modify and bla-bla-bla".
I am having same problem after sleep. And it was not present from the beginning. It may starts after I upload some app. I will play with this after coming back home.
yes please let us know thank you!

When my tablet is plugged in and it goes to sleep, the Wifi also disconnects, so I don't think this is a feature any more than the screen angle issue is a "privacy feature." I've never had an Android device that powered down connectivity when the screen goes off, that totally negates the notification features. You basically have a comatose tablet after a few minutes of the screen being off.
I don't think the Xoom or Galaxy Tab have this problem, so there's definitely an issue. Sadly, I might be sending mine back to TigerDirect as faulty because of this.
I have this problem too. As others have said, the problem isnt that the wifi turns off when the tablet sleeps. The problem is the last connected access point gets disabled so when you wake, you have to go into settings and tell it to connect again.
In my case, it happens most of the time, but not always. My Android phone doesnt have this problem.
I did a factory reset, then used nvFlash to restore, and then did a fresh install of Vegan (thought it did the same on every other 2.2 ROM I tried). I didn't install any apps, and the problem still occurs. Tried using Wifi Fixer, and the problem still occurs (though on the bright side, it does reconnect about 10 seconds or so after waking).
I'm out of ideas. I hate to send this thing back because it's the most fun piece of tech I've had in years, but a comatose Android device is a dealbreaker Going to try a GB ROM, and then I give up.
I've got the same kind of issue. I lose my PSA key in my wireless settings every time and have to re-enter it.
I installed the Vegan GB ROM (along with pershoot's kernel), and the wifi stays on if you choose "Never" for wifi sleep (you have to hit the menu button and choose "Advanced" when you're in the wifi settings). Only problem is, the GB ROMs, while zippy, are a little raw right now, and my Launcher Pro GMail widget doesn't work
I'm going to try one of the 2.2 ROMs again today along with pershoot's Froyo kernel to see if it makes a difference.
Ok, YMMV, but I am using Calkukin's ROM with pershoot's kernel (was using Clemsyn's before), with wifi set to never sleep, and my wifi doesn't sleep any more. I left my phone and tab here at work while I went out for lunch (felt naked ...), and came back about 45 mins later, woke the tab, and wifi was still connected, without that "looks connected, oh the icon is now disconnected, oh it's back again!" bit.
I still receive notifications and email, and widgets update. Guess I'm keeping it
Hi all,
The Wifi on my SGSII is constantly scanning even though it is connected to my home wifi network (a WPA/WPA2 PSK secured connection on a G band router). The signal strength is "excellent" and I have the phone sitting right next to the router. Further, I have network notification turned off ( unchecked) and under advanced settings, my Wifi sleep Policy is set to "never".
Sprint users have reported exactly the same problem on the Epic Touch 4G" (http://forum.xda-developers.com/showthread.php?t=1272226 ). Has anyone else been experiencing the same issue on their ATT SGS2 ? I would be very grateful if someone could post a solution for this issue.
Thanks in advance

PS: My wifi setting screen looks like this genteman's ( except i have network notification turned off)

Scan rate is bumped up significantly when you're in the settings menu.
Have you confirmed via logcat that it's scanning frequently outside of the settings menu? It shouldn't be in that case - but without logcat it's almost impossible to tell.

Entropy,
What should I be looking for in logcat? I have Betterbattery stats installed and according to that, Wifi scan time is 8+ hours even though Wifi on time is only 2+ hours. That doesn't seem to make sense, but what do I know.
I am running UnNamed 1.3.1.

I believe BBS is reporting scan time improperly. I've seen that in a few threads.
Sent from my GT-P7510 using Tapatalk
You're probably right, except now scan time doesn't even show.
I have also observed this on my phone.
I have a Samsung Galaxy IIs, using a Sony Ericsson MW600 BT handsfree as well as a Pioneer car Bluetooth handsfree system.
I have not measured anything yet, but I notice that when the Wi-Fi scanning is going on, I get significant disturbances on both of my Bluetooth hands-free sets. Listening to music is without a hitch, but talking on the phone (Norwegian GSM - operator Telenor) is terrible.
i also noted this after installing the OTA update to 2.3.6 today. I just rooted mine yesterday after reading 54+ pages to make sure i understood everything. i had a cappy and loved installing new roms but have not taken the plunge yet on the sgs ii. I haven't noticed a huge difference in battery yet, but it has only been a couple of hours since the update.
What ROM are you running? You can edit the build.prop to change how often it looks for networks. It is the line "wifi.supplicant_scan_interval=xx". I set mine to 180 which is 3 minutes, some ROM's set it really low. Also the scan rate is bumped up significantly when you're in the settings menu like Entrophy said.
Hi,
I had the same problem where my WIFI was fluctuating.... I dont know if this is the problem/ solution but this is what happened...
My SGS 2 is already rooted and unlocked. I had flashed the Entrophy DD 12/23 first then I had flashed Unnamed Custom ROM. After rebooting the phone, I saw the Wifi was not stable. So I again did a "Wipe Factory Data Reset" and "Wipe Cache Partition" and then installed the Unnamed Custom ROM from the SD Card. My Wifi is pretty stable now.
I am not sure if you guys had this issue when flashing a ROM but this seemed to fix it.

I have written about this wifi-battery drain a while back here in XDA.
When I used to have my Nokia symbian cell phone I used to flash custom roms
and there were a lot of nice new features after flashing.
A couple of the really nice battery saving mods were:
#1: added option to change the amount of wifi milliwatt output from 18 milliwatts (default) to 3 milliwatts
which is more than enough if the phone is no more than 20-25 feet from the wireless router.
(the mod gave the option of 3mw,6mw,12mw & 18mw)
Saves a lot of battery life.
Don't know why none of the DEVS have addressed this issue yet.
#2: added a mod so once the wifi establishes a connection it no longer scans
at all unless the connection is disconnected or lost.
So in other words, the phone only scans for wifi until it connects.
Right now I am connected to wifi with my phone and yet in settings it displays "scanning"
non-stop-constantly even though in wifi settings it displays "connected".
Why should the phone be scanning for wifi if it's already connected? (I have no idea).
Don't know why none of the DEVS have addressed this issue yet either.
Both of these mods really made a noticable difference in battery life
for for me since I do use the wifi feature in my phone a lot.
Hopefully one of the DEVS can look into these issues soon.
Now someone mentioned wifi constant scan, I noticed mine is doing the same thing. I leave the wifi setting screen on, it re-scans every 3 seconds!

Power control - Not likely, unless there is some documented power control already in the driver it's not going to happen. We're in a bad enough state as it is trying to make the chip not fire interrupts at 1 Hz on the Infuse.
Broadcom is one of the least open source friendly chipset manufacturers on the planet - their drivers have NO comments or documentation whatsoever, and datasheets are not available.
The rescan stuff is probably only addressable on Cyanogenmod, messing with it would require source code for the userland wifi management stuff.

As stated earlier in this thread - this is by design. It is assumed that if you're in the settings screen you want to change networks and have an up-to-date list.
I also am having this problem. I am running the rooted UKK6 from entropy512. After turning on my wifi, my battery drained from 90% to 70% in 5 hours with no use. My android OS is running at 80-90%. I don't have any extra apps except for 3g watchdog and CPUSpy and BBS. I do have Go launcher and GoSMS installed. As soon as I turn wifi off, i can see my battery level off under settings. I have searched for the last 2 days for a "fix". no luck.

Try doing a clean flash using "wipe data/factory reset" in CWM
recovery and then see if the phone has normal battery drainage.
(which it will if you flash the UnNamed v2.2.1 custom rom)
Then install one app at a time so you can find out exactly which
app is the culprit that causes your excessive battery drain.
This is the best way to trouble shoot battery drainage issues.
You will see that your battery drainage issue is not caused by
the custom rom, but it is caused by a few apps which are just
not very battery friendly.
The UnNamed v2.2.1 rom is the best custom rom currently
available for our i777 phones and it has outstanding battery life.
Good Luck!

I also am having this problem. I am running the rooted UKK6 from entropy512. After turning on my wifi, my battery drained from 90% to 70% in 5 hours with no use. My android OS is running at 80-90%. I don't have any extra apps except for 3g watchdog and CPUSpy and BBS. I do have Go launcher and GoSMS installed. As soon as I turn wifi off, i can see my battery level off under settings. I have searched for the last 2 days for a "fix". no luck.

This has nothing to do with this thread - This thread is talking about wifi scanning.
Drain problems - read my known battery drainers thread. A lot of people are having problems, there is no fix, and there won't be until all the people complaining start actually collecting some data.
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.

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.
Recently I disabled the best wi-fi performance option (I enabled it on accident while messing around with settings on launch day) which obviously increased my battery life dramatically by actually allowing my phone to go into deep sleep. But now I hit a new issue.
Before I go on, I want to state that I DID apply the SmartSync fix and that my data IS working while my phone is in deep sleep.
New emails I receive with Gmail app do not get pushed to my phone as they should. They are anywhere from 5-15 minutes late if they even show up at all. If I happen to turn my screen on, automatically I get the notification of new emails.
Is anyone else having this issue with Gmail or any other app? I find it strange that while I have data (wi-fi/3g) enabled and working with the screen off, emails still come in delayed.
Any help would be appreciated. I have searched around and most of the answers I came up with (regarding HTC devices like the One X) had to do with SmartSync messing up the connection or someone not having the notifications enabled. I'm at a loss 0.0
EDIT: I tested this with Google Talk had my main account up in Gmail and in another browser windows my other Gmail account. Added both of them, talked to my self, if my device screen was off, I would either get it 1-2 minutes late or not at all. Once I turned my screen back on, the notifications poured in. I also tried the same scenario with my main Gmail account logged off (in case it was canceling out the messages to my phone, which it wasn't) and I had the same outcome. I edited the title to reflect that this isn't a Gmail only issue.
EDIT 2: Did more tests, I tried turning Wi-Fi off completely and running the same tests as above to my surprise everything worked as expected. I initially thought it might be because of my 5Ghz Wi-Fi band, so I tried it all again on my 2.4Ghz channel -- had the same problems as before. Somehow the issue pertains to your screen being off and Wi-Fi being on.
EDIT 3: I just tried streaming Pandora and shutting the screen off (maybe WiFi WAS somehow shutting off) Pandora kept playing no problem. I messaged myself on Talk, got the notification right away. This is very bizarre 0.0 But it might confirm this only happens when the phone is in deep sleep mode... Still doesn't answer why it doesn't happen on 3G or why notifications sometimes still come through.
EDIT 4: Still no fix but I have discovered that for some reason if the screen is off ANY data doesn't go through. Let me explain better:
If I have some thing like Pandora running then it will continue to run once I shut my screen off. But if WiFi isn't being used and I turn my screen off and then lets say I try to connect to it with Cerberus or ping it from my PC or something it will not even though the router reports it as connected.
Very strange behavior.
This is interesting...maybe the wifi performance toggle is associated to the smartsync, and all?.....I will say that with it unchecked I am getting some really really good battery life here compared to previous phones....but I also notice at times when emails are not pushed till I wake the screen during the day....Also the fact my wifi doesn't automatically reconnect to my house when I get back from work till I wake the screen...little things like that...
Havent messed with the best performance setting but will try it today now...

Try installing this https://play.google.com/store/apps/details?id=com.logicvoid.powersaversettings&hl=en and unchecking "put data connection to sleep." It may not solve the issue but its worth a shot.

Have it, and it is unchecked. That's the weird thing, wi fi doesn't actually turn all the way off because SOMETIMES I do get the push notifications (late, however).

what is the smart sync fix?
When I installed this app, my cpu reduction and frame rate reduction was enabled. Does that mean this is standard with this phone. Does using this app to disable those setting improve the performance?
Issue continued overnight, tried various other things and nothing seems to fix it. I want to get my notifications but I don't want to destroy my battery life xD is anyone else having this issue?

It's definitely not a hardware problem because if that was the case the phone wouldn't work with wi fi almost at all. My wi-fi connection is rock solid even when the screen is off, just for some reason it won't notify I have the messages until the screen gets turned on.
I did some tests on my gf's stock phone and she's having the same issues, I told her to do some tests on her parents wi-fi when she goes there. I wonder if sgt slaughter has any news.
Btw if you definitely need them on time and need to be on wi fi but don't care about battery life that much just enable best wi fi performance.

Actually more like a Smart Sync break ... The built in settings/app put your data connections to sleep when your phone goes to deep sleep; this is done to save battery when phone not in use for extended period.
Some folks hate losing the data connections so a flashable "fix" is available for the "problem" ... Look around; you'll find it
Sent from my EVO using XDA
its a sense problem, there's a thread in the one x forums on how to fix it. I'll post when I get home if I can find it. it shuts down to a 'power save' mode after a while plus after midnight or 11 or something.
Just wanted to update that I installed a custom rom that contains the WiFi fix mentioned and although my WiFi doesn't seem to drop how it did before (at least after one day) my notifications are anywhere between 4-10 minutes late on average through WiFi. This seems to be across the board for Exchange email, Gmail & Google Voice.

Yes my setup also had the wi-fi fix, I can even see my phone connected to the router when the screen is off, the connection is strong.
I had a suspicion it was probably the basic transfer rate of the browser and for some reason I could not adjust this on my fancy 100 dollar router with dd-wrt flashed onto it so I set up a repeater with my older router on stock settings. It seems like the notifications are coming through better now (albeit not instantly) but at least I don't have to turn my screen on every time. It might be a placebo effect or just luck (because at times it does work even with my other router).
EDIT: Ignore the italicized sentence. It was just a stroke of luck, the problem came back.
I'm out of ideas at this point xD
I am having a similar issue as well.
I am rooted and running Fresh Evo LTE 5.1.1 which has the "Disabled SmartSync deep sleep mode" already installed. I also leave my WiFi off (for the same reason as the OP outlines - messages are just plain not arriving or if they do it's after I turn the screen on).
I use gtalk as my primary form of communication on my phone and what seems to be happening is messages from my two closest friends are never arriving. It's hit or miss but seems to be ~45mins after my screen turns off that they send a message and I never get it. One is on Sprint on my family plan and the other is on Verizon. The weird thing is that if I look in my gmail > conversations the messages aren't there either.
I haven't been able to verify any SMS messages that I haven't received but I have noticed that my email notifications seemed a bit wonky but this issue may be fixed with changing my "push" hours (which is retarded to have factory set to only push email between 8am - 8pm).
Question for the smart kids in the class: When does the phone reach "deep sleep"? Is it around ~45mins after the screen turns off?

I also have the dual core mod which I BELIEVE sets my deep sleep right away which is probably why I have the problem more often than you do. One question just so we can start gathering facts large scale, if you're on 3G do you have the problem still? What if you turn 'best wi-fi performance'?

Correct - I have this problem on 3G. I run on only 3G because the problem is more prevalent on WiFi, but still very common on only 3G.
Currently I have "best wifi performance" turned off. Do you want me to test with it on or off?

On. When I turn it on it pretty much eliminates the issue, it acts just like 3G. But for me 3G is almost perfect (a couple seconds of delay but I can deal with that). Remember though that if you leave it ticked on it will destroy your battery life.
WiFi is on, best WiFi performance is on as well.. I'll run it this way a couple of days and see if I can replicate the problem.
I just wanted to say that I've been having similar issues. I have tried turning on best wifi performance, but I don't think that is helping. For one thing, when I have that turned on, when I wake the phone, the wifi is often times not connected, and it shows 3G. Then it will connect to wifi shortly after I wake the phone. On top of that, I'm still not getting notifications on time. I was notified of an email when I woke the phone that actually came in 10 minutes earlier. Hopefully HTC/Sprint is aware and working on a fix.
Still no fix but I have discovered that for some reason if the screen is off ANY data doesn't go through. Let me explain better:

Hi All I have the Mate 20 Pro and absolutely loving it apart from the below problem.
WiFi keeps dropping out. It's definitely nothing to do with the wireless router as all other devices working perfectly and my previous SAMSUNG S7 never had any issues they only started when I got this new phone.
Unfortunately its causing serious issues for me as I can't get data connection downstairs and rely on WiFi.
I've read others have problems and apparently Hawai cut corners with the WiFi and put a poor quality device inside?
Is there anything that can be done or is this definitely a hardware problem and something I just have to live with I. E. Not being able to use it on WiFi?
It shows full bars on the WiFi status symbol top left but will connect one minute and the next minute can't even load a new page, Facebook comments, or will just pause and start spinning on a video.
Bump!! Same problems! My Galaxy S7 and S8 always worked flawless with notifications and internet connection switching between wifi and 4G. Mate 20 pro drops out. Now also remembering my old Ascend Mate 7 did the same. Huawei problem, but is there a solution?
I have tried various settings in the wireless and developer settings no luck. I cant seem to find the usual android settings to keep wifi on always...
Did you guys check under Settings/Battery/More battery Settings if "Stay connected when device sleeps" is ON?
Pretty stupid to hide it there (Samsung had it in the right place under WiFi settings) but whatever.
My Wifi NEVER disconnects at home or work and I DO get emails even if the app is set to pull every 30 min (so it wakes up properly and pulls data). Plus unlike my old S7Edge, WiFi reported power drain is always below 1%...so negligible.
