Hi,
I just bought a Sony Tablet S, amazing device. The only problem I'm having is that when the tablet is idle, or the screen shuts down, the WiFi gets disconnected and it doesn't reconnect untill I open the WiFi panel in the settings app.
Now before you guys jump to conclusions, yes, I changed the WiFi disconnect policy to "Never (uses more battery power)". That hasn't helped at all.
Any ideas? Is this just with Sony S or a generic Honeycomb thing? Tablet hasn't been rooted as yet.
Try Advanced Wifi Lock Free. It works well with my tablet.
This issue seems to be a bug in Tablet S. I hope they'll fix it in the ICS release
Yes, already discuss here...
You need to install a must have application...
Advanced Wifi Lock
https://market.android.com/details?...DEsIm9wb3RlY2guYWR2YW5jZWR3aWZpbG9ja2ZyZWUiXQ..
Worked
Thanks for the app recommendation. It's working...so far .
I bought my Tablet S 2 days ago.
Though I have heard of this issue before, my new tablet does not have this problem, maybe Sony has fixed the bug.
p.s. I changed the wifi disconnect setting to Never.
I started using wifi advanced lock a couple weeks ago and it works great! Much better than making sure the screen stays on during all your downloading
...Although I've noticed a massive change in battery life. Typically I was always getting 7-8 hours of screen on (gaming) time out of it, with up to an additional 24 hours of time with it on standby.
Now I got about 13 hours standby and 4.5 hours screen on time with wifi constantly on.
All I'm saying is to have a widget for turning on/off wifi quickly, and leave it off when it's not in use. I didn't think that wifi made THAT much of a difference..but apparently it does lol (and that was still without autosync on either)
I uninstalled that and use spare parts instead. Advanced wifi lock was horrid with my battery grrr
I think is normal, because if you put your tablet in standby is because you're not using them so why you need wifi on?
When you turn on again the wifi will reconnect auto again
WPS Wifi Lock
I had the same issue when connecting at my house, If you have a WPS enabled routter, connect to you access point using WPS. At keeps the signal locked.
1. disable auto sync'ing on all apps such as email. I'd rather manually refresh when I use the particular app
2. Force Stop Google Maps from the Downloaded Apps list, not just stop it on the Running list. This stops Maps from restarting itself
3. Set wifi sleep policy to "Never when plugged in". All battery tips say to set wifi sleep policy to "Never". I don't think it's right for tablet. Let wifi sleep when not using it, unless you are downloading movies or tv shows then plug in the power.
The change is I used to recharge every other day, now I recharge every 3-4 days. Hope you get good results with my suggestions too.

thanks for the tip. another one is not to use auto brightness and try to keep brightness around 25% or less.
I actually froze maps with TiBu. I'll use it on my phone if I need it. It seemed to help a ton. Also, I turned ips+ on and turn brightness all the way down instead of leaving ips+ off and turning brightness up a little, I don't know if this actually helped battery or not but it kind of seemed to to me.

If I've helped you in any way... hit the "Thanks" button.
I find that not using my prime helps to preserve battery life..... C'mon guys, android is not a day old, and all these tips are more common sense nowadays than acquired knowledge. Meanwhile, I commend OP for trying to help.
OP, point no2, it depends wherever you allowed Google to use location at setup (you can change it in settings), you can shut it down all you like, but as soon as you use an app that needs location service is going to restart.

If your WiFi turns off when your tablet is sleeping, I don't think it is necessary to disable auto syncing of apps, since they won't sync without a data connection anyway.
Also I don't know what force stopping Google Maps is supposed to accomplish. Again if there is no data connection it isn't downloading or sending information it most likely isn't using any CPU.
The most important setting here is to disable WiFi when the tablet is sleeping. That is the only setting I have changed and I also get 3-4 days of battery life with moderate usage between charges.
How I cut down battery drain when I'm not using my TFP:
- Power it off

I don't have the option that says "never when plugged in". Mine says "only when plugged in".
I still get crazy good battery idle when undocked. I wont lose a percent for over 10 hours of standby. when it is docked I lose 1% every 2-3 hours. I've tried every setting but it still occurs

What standby setting are you using that you aren't losing anything in 10 hours???
I've been thinking about this for a while

Same here.
Which got me to thinking, and this is only my common sense here.
On standby it's clear why the dock's battery shouldn't be draining, but when in use the dock needs some sort of power to run. The trackpad needs power, the keys themselves need power, when you push capslock it has a light that turns on which also needs power.
It seems that using it's own battery instead of the tablet's for power consumption while in use is the right way to handle this, and that would also make sense for a higher battery drain when not is standby mode as apposed to standby mode.
Just some of my thoughts.
Sorry you are right. "Only when plugged in"

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

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:
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.
Someone started a thread a while back on this, but I wanted to start my own hoping that this issue may get a little more attention, and keep a detailed thread for future use. I love this phone, but this is the one significant issue that I have.
I spend most of my day and evening on wifi since I have it available at work and home. I've noticed since day one that I wasn't getting my notifications on time specifically in Gtalk, and still exists to this day after the latest 2.13 OTA update. When I hear my phone get a notification, I will check it, and the notification has a timestamp in the notification drop down, so I know I got it just then, but then in gtalk the timestamp on my message is several minutes earlier. I have seen it as much as 45 minutes late. It is very noticeable whenever I turn on the screen that instantly I get a notification. The issue exists with all push notifications. Gmail notifications will arrive late as well as exchange notifications. I've seen reports about it happening with WhatsApp messenger. It has been theorized on other forums that the wifi radio goes too deep into sleep for the notification to wake the phone up.
My wifi policy is set to stay on always. I've tried factory resetting. I know that the wifi stays connected while it is sleeping and is not disconnecting. I've tried multiple wireless networks. I've tried 2.4ghz vs 5ghz. It has nothing to do with smart sync disabling data as this is happening during the day and not between the hours of 12am and 7am.
I have done a lot of searching on Google about this issue, and I've determined that it is an issue with the entire line of HTC One series phones. People have reported this issue on the One X (International and ATT), the One S, Incredible 4g, and of course many other reports on the Evo LTE.
I have compiled many of these reports in a thread I opened on HTCs support forum site here: http://community.htc.com/na/htc-forums/android/f/222/p/15183/62995.aspx#62995
Please feel free to test this yourself. Connect to wifi, turn your screen off, send yourself a gtalk message from a separate account. If it comes in on time, wait about a minute and try again. If it doesn't come in, wait as long as you can stand or just turn the screen on, and see your notification come in. I tested this on a friend's Evo LTE who insisted he wasn't having the issue, and I was able to duplicate this. It seems that most people must not use wifi as much as I do, and maybe just haven't noticed.
Current solutions / workarounds:
Turn on Best Wifi Performance in the advanced wifi settings - kills battery
The best solution that someone found on another forum was to use an app called REGPON Wifi KeepAlive. It is an app that puts a partial wakelock on the phone in order to keep it from going into deep sleep. Check both boxes included in the app. The first starts the process, and the second will turn it off when wifi is disconnected. This doesn't have a huge effect on battery as I thought it would since it is putting a wakelock on the phone. I actually get very good battery life still, and can last through the day with heavy usage. It's nowhere near the significant drain that you get with the Best Wifi Performance option.

That could be considered a workaround, and I have tried it, but wifi doesn't go to sleep until after several minutes after you turn the screen off when you use that setting. Then of course mobile data kicks in and notifications come in on time.
Hi guys, my mom have a D618, she's old so dont know much about Android. She want a long battery life so I rooted her phone, installed Greenify and disabled some bloatware app.
But sometimes I check the phone and notice that wifi cant turn on. I mean it seems to be turning on (wifi icon in quick setting blinks) but it can not turn on. I have to reset phone to fix it but this issue still appears after some days. I couldnt check her phone always so that it even if happens day by day make drain battery so much. I dont know what causes it, and how to fix it completely.
Is there anyone also get this issue like me? Fix experience? Thanks
No one can help?
