Tethering fast while display on, slow while display of

Hey guys,
i have a weird problem. I'm depending on the wifi from my neighbour atm (he gave me the key - everything legit ) and i tether it via my Desire HD to my PC. But there's this strange behaviour i discovered: When the Display is turned on, i get a ping of about 30ms. When the Display turns of it rises to about 600-800ms.
I have a rooted DHD with Cyanogenmod 7.0.2.
I tried to fix the CPU speed to 1GHz - Performance with SetCPU but it didn't help and i set the wifi connection not to go in standby whilst the display is off.
Does anyone have an idea about this?
Jack

It seems that some of the DHD's Hardware does go into standby although you disabled a few options.
Maybe this could be solved with another kernel, but i guess you would have a higher battery drain then, even without tethering.
Why don't you just leave the screen on? Start its desktop clock and it'll be a nice gadget on your desk

Hi Jack,
I have a base rom or whatever it is called. I have the same problems. I tether using my 3G connection. When the device display is turned off, the tethering has speed issue, while it is turned on, tethering works fine. I haven't found a solution yet. i just keep my display on, since its connected to pc, it will be in charging state.
Regards,

Hey guys,
thanks for your replys, the best idea would pobably be (for now) to leave the phone in "desktop-clock-mode".
Thanks for your Help

Not a fix but a work-around...
Since I guessing the phone is connected to the PC, could you not set the phone to not sleep when charging (menu -> settings -> Applications -> Development -> Tick "Stay Awake")? That way the screen will stay on when ever it's charging be it mains or via USB
(EDIT: Appreciate you get this using desktop clock but this saves having to mess about every time.)

Change your wifi power saving options. The behavior you get is default, to save battery life. It's under the advanced settings in the Wifi settings, IIRC.

If you're talking about the sleep policy the OP says he's done that already.

Changing the sleep polici doesn't do it
Thanks for the hint with the display staying on while charging!

[Q] Hibernate/Standby Mode

Is it possible to have a Hibernate/Standby mode on the Transformer? Not just a screen off setting. I am used to putting my netbook into standby, hitting a key, and everything ready to use within a few seconds.
With the current screen off setting, the wireless stays on, I stay visible on gTalk and messages end up going to my Transformer instead of my phone. Also, I would think battery life would be increased.

I would check your settings as my wifi disconnects when screen off
settings located
Wireless & Networks
Wifi Settings
Wifi Disconnection policy
mines set to When screen turns off
Not sure about Hibernate state on android at all others may know

Did not know that. I had just been turning wifi off because I noticed that even withe the screen off it was draining the battery faster with with with wifi enabled.

Wi-Fi Not Allowing Deep Sleep

So I posted this in a different thread but figured I would post it here to see if anyone could duplicate my findings. I have a Note3 from T-Mobile and for whatever reason leaving the Wi-Fi on will not allow the phone to go into deep sleep mode. I noticed when I was down to 40% battery after 10 hours with only one hour of screen on time. After running some tests I had only 2 minutes of deep sleep those entire 10 hours (tested using BetterBatteryStats) I tried setting "Keep Wi-Fi on during sleep" to Never and unchecking "Always allow scanning" under advanced network settings but neither of them fix the issue. In fact, after several tests I concluded that setting never for "Keep Wi-Fi on during sleep" wasn't even functioning as my access points still showed the client connected while the phone was asleep.
Can anyone else confirm this issue is actually a bug and not just my phone being defective?
Here's my original post on the topic regarding how I found the problem and what I have tested so far:
OK so after only 2 days of owning this phone (got it late Monday night, the T-Mobile variant) I finally figured out why I'm getting such bad battery, and I suspect the same thing may be happening for the other people in this thread. Hopefully this information helps at least one person.
My battery stats was almost identical to all the other users in this thread that had bad battery, I would get barely around 10-12 hours on the phone with less than 2 hours of screen on time. After using multiple apps to track down the issue I finally got what it was.
Wireless. Yes, wireless was my cause. But the thing is Wi-Fi didn't show up at all in any of the battery apps so I assumed it was a non issue. I've had other phones and have always kept the wireless turned on the entire time without problems. The basic problem is not that Wi-Fi is using power itself but it's that by default the phone cannot enter deep sleep while connected to Wi-Fi. This is why trying to use apps like BetterBatteryStats will lead you nowhere initially (though they were useful in finding out what was causing the issue) You can discover this by turning on Wi-Fi and connecting the phone to a charger, then disconnecting it so your BBS information will reset. Then power off the screen and power it back on after 10 minutes. You'll notice in the other section that deep sleep will have less than a minute time while awake probably has close to 9 minutes, if not more. This is with everything else turned off, almost no apps, and no special Samsung stuff enabled.
Under Apps > Settings > Wi-Fi > Menu > Advanced there are two options that should help this: "Keep Wi-Fi on during sleep" and "Always allow scanning" I set the "Keep Wi-Fi on during sleep" to Never and unchecked Always allow scanning and rebooted the phone. And low and behold...nothing. Yes, these options don't work (at least not to fix this problem) The phone still won't enter deep sleep mode while the wireless is enabled. Based on my company's wireless devices I can see that even with the screen off for well over 10 minutes it still shows connected as a client meaning the wireless is not turning off properly while it's in sleep mode. Or perhaps it can't go into sleep mode because the wireless is on which stops it from going into sleep mode and turning off the wireless. My guess is that it's a Samsung bug.
The reason why there's so many people here to get good battery usage is because they're either used to turning Wi-Fi on only when needed and keeping it off. You'll also not notice it if you have more than 6 hours of screen on time because you could easily assume that it would make sense that you phone would only last 10 hours total with that much screen on time, even though it should have technically lasted 20+ hours with only 6 hours of screen on time if the phone could have entered deep sleep.
So what's the real fix for this? Unless it's by design my belief is that it's a bug and won't be fixed until Samsung/T-mobile notices. I can't test to see if the same thing happens on other carriers so if someone feels like testing this theory out it would help.
For now, I guess we're just left to manually turning Wi-Fi on only when needed and leaving it off in all other cases. For those that have the T-mobile variant, make sure you also go into Settings > General > Backup and reset > Collect diagnostics and uncheck the "Allow Diagnostics" as that will probably be the highest offender of Partial Wakelocks (it'll show up as com.carrieriq.tmobile.wakelock or System Manager Application)
If anyone wants more information on my testing let me know!

That's because the 'Keep WiFi during sleep: Never" setting only disconnects, it doesn't shut down the WiFi radio.
You're going to have to use a manager (Like Deep Sleep Battery Saver).
Or just hit the toggle yourself... If you're going to keep it disconnected in sleep anyway, just swipe down the notification bar and hit the bloody toggle.

The problem is that it doesn't disconnect, the access point 100% shows it is connected and transferring data every now and then. But the real issue isn't weather it disconnects or not but it's the fact that Wi-Fi will not allow the phone to go into deep sleep mode. For now I am fine with switching Wi-Fi off and on as needed, but with no other phone have I needed to do this before and definitely seems like a bug.
But regardless, what I'm trying to figure out if this is a legit bug that I should submit to Samsung/T-mobile or if it's just my phone and I should ask for a replacement. If anyone has BetterBatteryStats and could test this with their Note3 that would help.

My stupid phone has just started this same issue!!!! Freaking annoying, after only 8 hrs from 100% charged state, the battery is at 46% with only 26 mins screen ontime, I checked out that the phone never goes into deep sleep. What is going on and what can be causing this? Did you manage to resolve your issue?
PS I checked out wakelock detector but doesn't tell me a thing, as what program is keeping the phone awake all the time. Starting to hate this phone and miss my S3

What is your GPS accuracy setting set to? GPS, Wifi or Networks? Try setting it to GPS only.

Well, your issue looks pretty similar to mine, which I solved with this Xposed mod (you could give it a try if you're on KitKat): http://forum.xda-developers.com/xposed/modules/mod-wi-fi-deep-sleep-t2752947. I was experiencing that even when "Keep Wi-Fi on during sleep" is set to Never, Wi-Fi still was awake most of the time according to battery stats.

"Wifi off during sleep" but frequently turns on/off even during sleep?

Noticed in battery settings that my Wifi turns on and off frequently even when my device is sleeping. Doesn't seem to be affecting battery life but I'm wondering why it does this. It happens on both my Nexus 7 (stock rooted) and my Nook HD+ (CM11). I do have the "always scan for networks" settings off.
Attached screenshot is after I didn't really use my Nexus 7 for about a week.

I would imagine this is caused by certain apps requesting data. For example, your Gmail app may be set to refresh every one hour, which means it needs to use the WiFi to search for new data and download it, if needed. Other apps are similar to that as well, depending on your settings.

If it really miffs you, you can always use tasker and create a task that shuts the wifi (I have it put it in airplane mode since it does several things in one shot) off when the display goes off and back on when display comes back on...will need to be rooted.

[Q] Wifi Always allow scanning turns on automatically and shows in battery usage

Hi guys
I noticed countless times that randomly when turning on wifi and then turning it off, the "always allow scanning" under advanced options is ticked.
I noticed this because then under battery usage you will see wifi active even tho main switch is off and 99% of the time that is why.
Is it a lollipop 5.0 bug or is it some of my apps that can switch that option when they detect wifi has been activated?
Also, it seems that if i dont turn on wifi in the first place, that option never becomes active. Battery life is very good on my phone so not a deal breaker....
Anyone knows?
Thanks
