Cell standby? Disable fast boot. - HTC Flyer, EVO View 4G

I'm bringing this up because I've noticed that as people ask about cell standby using the battery on WiFi only Flyers, this fix hasn't been mentioned as much. Sure, you can pull up the calculator, type in a code to get the tablet info screen and turn off the radio (or use AnyCut to make a shortcut to tablet info), but the radio is back on with the next boot. If you go into settings and choose "Power", you can untick and disable fast boot. Plug the Flyer in, let it fully charge to reset the battery stats, and cell standby doesn't show again in battery use. Ever.
This has been the fix I use, because it is persistent. When you power off and boot up again, the issue doesn't come back.
Can anyone explain how this works?

im curious what code put into the calculator to bring up the Tablet Info

In the calculator, enter: !+!+4636+!+!
and hit = .
Then, click "Turn off radio".
Or, just turn off fast boot, reboot, and let the battery charge and cell standby won't show in battery stats again.

[Q] phone not powering down completely

have you guys noticed that when you power down the phone it does shut off but not completely. the reason i think that its not fully shut down is because the phone boots back up within seconds of powering on....also the up time and awake time have not been reset back to 0. this actually is the only way my phone goes to sleep. any other time when i just turn the screen off my phone won't really sleep (wake lock)..ive noticed this with the blackend rom and also infected rom...the way i found to fix the wake lock issue is to do a factory reset which fixes the problem until i have to charge the the phone which everyone knows that the phone won't sleep while charging. so have you guys experienced this? and also do you know whats causing the wake lock? ive searched the forums and cant find anything...thanks!!
Fastboot, in the power menu, turn it off.
ok turned off fastboot and this fixed the up time and awake time not resetting...still having the wake lock issue tho...any other ideas to fix this?

When you reboot your phone, it does not turn completely off because you are rebooting the phone. It is a feature added by htc to speed up reboot speeds. When you reboot, it kills all apps and processes, goes to sleep, and boots up.
Turn fastboot off (menu>settings>power>fastboot) if you want it to turn completely off while rebooting.
To make the phone sleep while charging, go to
menu>settings>applications>development and uncheck "stay awake"
went to my setting and the stay awake while charging was unchecked already...actually i dont mind having wake lock while charging...just the wake lock with normal use...thx tho

[Q] Low battery - touch screen not respond

Hello guys, I just noticed strange bug/behaviour. If my battery is around 10%, touch screen is not respondig as it should (also touch buttons). I have to tap like 10 times on some tile to open it and then tap another 10 times on back button or home button to jump of from app. As soon as I connected the charger, phone is behave normal, like new
Does somebody else notice the same behaviour or its just me?
P.S. Tried to reboot phone twice. Battery saver was off.

Can you check under settings -> applications -> Background tasks?
It more looks like plenty of apps are trying to sync up or use the resources. I might be wrong, but this did happen to me even at about 55% battery. But not as bad as 10 taps. I just felt the app launching was a lil slower than normal when I had ample background tasks.
Didn't know about "Background tasks", thanks
Currently I have only "HTC Hub" there. I will go and check this setting next time when I occur this problem.
But anyway, shouldn't reboot kill all background apps?

Reboot surely will kill all background apps. But these background apps are different to other OS. They are those that will 'start on boot'. So after reboot just in few seconds, they will get to their business as usual.
I love this 'background' task feature! No other OS does it so efficiently as Windows.
The good thing is if you check that place often, you will know what apps are 'going to run'. It doesn't mean they are running all the time. It tends to indicate the capability of them to run.
So as you said you just have HTC Hub, which is same on mine. However, when you to go 'advanced' option on that same page, you will see a list of greyed out apps that are going to run in background and you can't kill them. Reason being these apps need to be told about not running in background by entering them individually.
See if that greyed out list has some huge apps. I downloaded this gMaps thing from market and although I just looked for maps once (a day ago) since then, it's been running. It's because it kept on looking for my GPS co-ordinates. Now that dint freeze my phone (1.5 Ghz, I know!) but it drained battery quicker. Changing attributes within the app, removed it from greyed list and happy days!
In a nutshell, very intelligent task management. You can choose what can run and can't run while your screen is off! + you get benefit of battery saver option if you use that so you can choose who can connect to 3g network and who can't while you are not looking at your screen!
PS: whole point of that long post was : Most likely it's not a background task that's hogging your processor, but it's worth looking under advanced and you might know what app was it.
Hey, that was a long post Thanks for clarifying. I just checked Advanced tab and there are only HTC hub and some Media something (I have it in Czech so don't know the exact name in english)
Anyway I will keep my eye on that menu and in case of any issue I will check it and we will see
OK guys, here is the update. It's still happening :/ Everytime battery drops under 10% phone cannot be almost used. I have to tap everything 10 times to get it done. Checking background task was not helpfull, only HTC Hub is running (even if I kill it its the same).
So...I don't know...maybe its a bug (some power-saving feature thats is not configured properly?). I was used to behaviour when my mobile works even with no battery left like fully charged. No change in behaviour...

As a last resort - try a hard reset. I've got many issues fixed that way.
However, can I ask how closer to the release did you get this phone? Here in the UK there seems to be two separate batches dispatched. One which was at the release - which is buggy batch. I got my new phone sorted from someone I knew at the store and so far not a single problem from the earlier handset is seen. Battery is drastically better too (it was better on earlier one already, but this is very pleasing!)
Try hard reset, if that doesn't solve it, I would recommend to swap it if you can.
Hello everyone,
I am facing the exact same issue on my HTC Titan - when battery is low (battery saver turns on), touchscreen becomes unresponsive. This is very annoying since it usually happens when i get an incoming call and i cannot answer it.
Did anybody try hard-resetting the phone in order to solve this issue?
Thanks for the answers!
Regards
Hello there... I have the same problems too. I don't try to do hard rest for my titan. It is very annoying for me. Also some time my touchscreen becomes unresponsive even the battery charging is more than 50%...
Yeah, I get this issue too, it makes the phone unusable until you get to a charger. I find that it comes in stages, it sometimes is really bad then works for a few seconds, then stops again.
I have checked all my background tasks and nothing is really running.
I have this issue too. I got this phone only yesterday, and when my battery reached 10%, touchscreen became unresponsible.
Guys I think I've mentioned this in the FAQs thread, but ..
Everyone with this issue - please tick the box under battery saver, where it says 'automatically start.... '
If you phone goes below 25% without battery saver ON, it will lag/freeze - the screen response.
However with battery saver on, you will be able to use it till you go below 5% or even 3% when it gives you the 'critical battery' warning.
This is HTC screwing with us!
mine has the completely opposite problem!! when the phone is charging, the screen becomes very unusable, in ex. i press the phone tile, the screen registers my tap, but it understands that i pressed the tile below or next to the one i really pressed. or i happen to scroll down or up, the phone hesitates for a second and then scrolls but it is very jumpy and jittery, unlike normal use. some times it doesn't even register my taps 2 or maybe 3 times in a row!!
the only workaround i've found is not to use the phone when charging
is this happening because of a faulty charger, maybe the phone is experiencing a short circuiting situation??
(i forgot to mention that i have the phone only for a week!!)
thanks

I have battery saver enabled and even with the heart icon in the info bar at the top, the screen is still unresponsive.
Same here! i thought it was just my device that was dead or something, even since it's only 2 months old!
I did a hard reset and it solved the problem, it must have been something messing it up.
Nope...I have tried Hard Rests...ROM Changes etc...but its still the same problem..
Does anyone here think its a hardware problem ? or something else?
Any geek suggestion would be helpful
Send it back to htc, let them repair it?
Sent from my HTC using Board Express
Hi, I also have a problem with non-responsive screens but only in specific areas and doesn't have to be 10% percent or lower.
Ex: It happens only when the keyboard is up and the buttons on the bottom are very difficult to press!
I'll provide pictures soon

That happened to me today. Then I did a hard reset and now my phone won't go past the carrier logo (the one after the HTC logo, and before the windows Phone logo)

[Q] Sleep/awake

Hey, at times, I have noticed that when I go to check my battery status, the "awake" part shows as a completely solid bar. That means there are lots of applications running in the background zapping my battery power. I have tried using task killers to stop those applications, but it still shows my phone being awake all the time, even though I have had my screen off for most of it. I think I read somewhere that when the phone has the screen off for a while, it would put itself in idle mode, shutting down other applications to save battery, that that never happens to me. I press the power button and the screen turns off, but that is the only battery saving I am doing with that. Is there any way I can put the phone into a sleep like state when I want? I do not want to turn my phone off all the time as I obviously need to use it, but I just do not want that much battery loss when I have the screen off. Thanks in advance for your help!
install betterbatterystats and bad ass battery monitor and find the app that sucks battery. disable or uninstall that app.

[Q] Battery test option - in Service Menu

When accessing the Service Menu on the x10, and clicking Service tests, one of them is a battery test.
When selecting this a message comes up saying it will take several hours. But nothing appears to be happening - the screen shows the battery % going down but that's about the only thing that changes. There is a "Result:" field at the bottom which just stays empty.
Then, when the battery empties the phone will just go off anyway. Does anybody know how the test works?

I believe you need to fully charge the phone while you're in that test.. upon fully charged the Result: field will show you that it is currently testing..

[Q] cobalt 80 can't fully power off to calibrate battery

i'm trying to sort out the battery on an archos cobalt 80. at the moment it has the latest stock firmware available from the UK archos support page. i restored it to factory settings from the recovery menu earlier today.
i'm fairly sure the battery isn't dying, because just a few days ago i had it working all day from a single charge, although now it will barely hold a charge at all. thing is, it doesn't seem to be possible to fully power it off, which is necessary to properly calibrate it. it apparently should be possible to switch it all the way off then plug it in so as a battery charging animation appears on the screen, but this thing just seems to go onto some sort of standby mode. if i try to charge it with it switched off, the damn thing switches itself back on again. i've read that it should be possible to power it off properly from the recovery menu, but the option simply isn't there, only reboot. it says that it's recovery system v 4.00.
is there an older/newer recovery image for this tablet that i can flash that will allow me to properly switch it off, or could i do it by installing CWM? or is there a secret button combo that will properly power it down?
