tmobile htc hd2 wifi/battery problem

hey you guys, i was trying to turn wifi on my phone off today and when i went into settings, the wifi icon was on the "green on" switch, but it was kinda grayed out so it wouldnt let me turn it off. do any of you know what the problem could be? thanks, also my hd2s battery dies really fast, it only lasts a few hours and drains really bad when im listening to music , even with the screen turned off, i know that battery problems have been posted all over the forums but has any fix been released? or should i just get a new battery? thanks

You Battery is Dying fast because of the WiFi being left on. Try to re-install the ROM. Also please give more info regarding the ROM you are using. So I could help you further.

The wifi icon being gray means it's turning on or of but in your case I believe it's simply stuck. If reboot doen't do a trick, reinstall ROM or install another one.

Battery Drain, almost solved. Need help from Dev.

Hello Everyone.
There is a battery drain issue in in cell standby and I think I just solved the issue. Let me go back to when I last experienced such an issue. It was when I flashed a ROM for my SGS1 Captivate called Cognition. There was a bug that left wifi not only on but it was active during sleep mode.
http://forum.xda-developers.com/showthread.php?p=12294219
It was later solved by the Dev and the draining went away.
What is different here is that the SGS3 only has this bug when wifi is on. Look at my battery charts when I have wifi on and wifi off. The red area shows the slope with wifi and the blue area shows it without wifi. This is during standby times.
So is this due to the wifi dual banding just taking up more battery? Or is the phone not properly tuning the wifi down in standby? Solving this issue is out of my hands now and I will have to hand this over to someone else.
For now, change your wi-fi sleep policy to shut off when in sleep mode.
EDIT:
So I think i figured out why the wakelocks are happening. Other people have the problem with dynamic IP addresses.

I don't know why these other fanboy war threads are bumping and so popular but a serious problem doesn't even get a response or a second look. Does anyone else have any comments on how we can get this fix? We need Samsung to fix this problem too.

I will make this post for two reasons;
To bump the topic
To say that i would also like this "bug" to be solved

hi slim,
I agree with you here as well. However I've not noticed any battery drain. I've got about 35% left after good full day of use.

I'm experiencing some kind of battery drain too with sgs3, but mine it's not wifi related. I have as first voice in battery stats page Cellular Standby. I mean, it's almost impossible it drains more then the screen!
Anyway, giving a look at your screenshot, I can clearly see some areas you didn't red boxed when wifi was on, screen was off but battery drain was not terrible at all.
How do you explain them?!

Yeah, I mean my battery life is still good, but I know it can be better. Now that I made it turn wifi off when it's asleep the battery life, the slope you can see there in blue, is a lot better. It's not so slanted and draining as quickly.
A lot of other people that complained about bad battery life I noticed the same trend, it's their wi-fi also. If you notice the long blue line on the bottom, that's when wi-fi is active and those extreme slopes have to be caused by wifi. Cell standby shouldn't be draining the battery more than the screen I don't think.
It's either wi-fi, the radio or both.

I don't know, I guess that is when the wifi properly shuts itself off.
When I look at my screen while I'm not doing anything at all I can see the orange arrow on the wifi on, and it stays on even though I'm not using the internet or anything. What can that mean? Is the orange arrow "uploading" or "downloading?"
EDIT: It's downloading. And I set the wifi to shut off if the screen shuts off. The Wifi sometimes shuts off. But right now it refuses to turn off even in sleep! And the orange arrow is lit up!

How do you get the wifi to shut off when the screen shuts off?

It's there in advanced wifi settings.
Did any of you people tried flashing different modems to resolve this?
《tapatalked from galaxy s3》

If you turn off the wifi then wont it just use the normal data connection and so use more battery? I was led to believe that using wifi was less demanding than say 3g.

Yes that is correct, but read my OP and the thread I posted. A wifi bug is the wifi not powering down in sleep mode. It stays on at full power during sleep and drains your phone.

No, some turn off the wifi radio if the phone goes to sleep

I tried a couple of modems, but in vain. Cell Standby is always much too high. Wifi is beyond good and evil.
I would by now also lean towards a bug. Unfortunately I'm not a Android dev. My knowledge ends at developing apps.

I am satisfied with mine

ive noticed smth:
with Droidwall blocking everything -> still wlan sends smth & causes traffic
hows that possible? u guys can experience the same?
under 3g/edge and droidwall everything blocked: no traffic anymore -> everything is ok!

Have any of you guys tried easy battery saver? One of the features is to disable radios when screen is off. I wonder if it is more successful in doing this than the built in setting.

I got the same cell standby problem so I went ahead and flashed Omega ROM, yesterday was my first day full with that ROM and the result was quite good. I ended up with about 45% battery after about 15-16 hours. Well I'm on wifi for like 3-4 hours though.

Drain caused by exchange sync process. Kill this process and see how battery life will change. Sorry for my english.

Curious, which F/W are you on? I was getting oddball WIFI battery drain using an older LE9 insecure kernel to root at first (WIFI would actually shut off and come back on after coming out of idle... even though I had it set to "always on.")
Completely went away after I flashed back the stock LEF kernel that my phone shipped with.
For reference below, no drain issues during idle with WIFI left "always on."

[Q] Phone doesn't go into deep sleep + wifi always stays on

This is very annoying, I have spent the whole morning trying to find a solution for this issue. The battery runs out already fast as it is, and now the phone is not
Battery drained about 20% at night by itself. Currently draining about 1-2% per 5 minutes when idle. What do I do? I have looked on various different threads for a solution, but did not find anything to fix this issue.
How do I fix this?
Thanks, in advance.

Also some details.
I had my phone at home, I prefer the phone to use WiFi networks when syncing and updating, but to have phone turn them automatically off when not using them, that is when the phone is locked and not syncing and updating anything. But apparently it doesn't do that, it has WiFi on at all times for some reason. And I don't know if its related to WiFi, it doesn't appear to go to "deep sleep"

For me, it was the last Google Maps update. Try to disable "Reporting Location" and "Location History" under Location settings on Google Settings app(the one with the green icon). I had around 25% drain over night and half of it came from this.
Try it and see if this can help you.
:fingers-crossed:

Like above say, disable location, especially if you keep wifi on.
Leaving wifi on while sleeping itself is not good for our health anyway, so if you have data switch to 2G, its at least enough to keep internet messages coming while saving battery. And if its wifi wise, apply pm.sleep_mode=1 in your build.prop. AND, scroll up a little, wifi_supplicant_can_interval(something like that, from its SHOULD BE 15 change to 300-600).
Disable unused apps and use greenify.

Thank you for the answer, but sadly it didn't seem to do it. My WiFi is still always on, even though I have it set to turn off when phone is sleeping at WiFi advanced settings.
Although the phone entered deep sleep mode when I manually turned WiFi off, but I'm not sure if that was the case.

I understand, but I forgot to do so, I actually have an app that turns on air plane mode at certain time. But that still doesn't fix the issue that the phone doesn't enter sleep mode with WiFi on and doesn't turn it off, even though it's set to do so.
Also I did not quite understand what you were telling me there, as I got the phone last week and it's my first android phone. The app you suggested could cut it, but that means that whenever there will be an auto check for news sequence I will be downloading it with mobile data? Is there an app that could cause this?

I was about to update on this, but I just got notification about 4.3 update. :laugh:
I will update this post, if this problem still exists.
UPDATE : Of course, still the problem persists, Phone goes to sleep when I have Wi-Fi turned off. But when on, even though I have it set to turn off during sleep mode, it keeps the phone wake and drains the battery.

How is it related to my router exactly? My iPod disconnects from Wi-Fi no problem.
Thank you for trying though.

I had left my phone this night with Wi-Fi off, but mobile data and 3G was on, Lost 7% in 7Hours from 47%. Does this seem okay, or a little bit too much? By the time I answered 2 emails and made 1 short phonecall and checked on battery logs from 2 different apps, and changed my wallpaper, battery has dropped to 33%. I'm not proud.

The answer to your problem is JuiceDefender Ultimate, available from Play Store.

Unfortunately this is normal, the battery life is not the best feature of nexus 4. How many screen on time hours do you get averagely?

This fixed the Wifi always on issue for me.
Turn WiFi on: Settings, WiFi, Menu (3 dots upper right hand corner), advanced, uncheck scanning always on.
Hope this helps.

Cell Standby Battery Drain

Hey everyone,
I picked up a T2 on Thursday morning coming from a Maxx, and after the first day I felt I wasn't getting quite the battery life I should. After watching the battery stats and doing some research, the issue seems to be due to Lollipop's well-documented cell standby bug. Coming from KitKat I have been pretty frustrated by this, as my T2 will sometimes drain 5% or more in an hour of idling if WiFi (or possibly Bluetooth) is on, and seems to drain much faster with use if WiFi is on. (Note that all of this is taking place in areas with very strong 4g and WiFi signal).
When WiFi is turned on, Cell Standby tops the battery consumption chart by a large margin and my unscientific eyeball test suggests that the battery drains much faster.
Is anyone else having this issue? I'm considering taking the T2 back, but honestly there aren't any other new phones with comparable battery life, and it would be hard to give up the shatterproof display. Other than this I'm loving the phone and Lollipop.
Thanks!

I'm not having that issue at all and I leave my WiFi on pretty much all the time. I just checked mine and in 13 hrs my cell standby was 8%. Honestly idk if that's good or bad.

I guess I'll just keep an eye on it. Over this past night Cell Standby was on for 10 hours and had the Mobile Radio on for 8 hours while the phone was idle. Not sure if this is intended or not. My battery woes could just be in my head.

cell standby has been near or at the top of all 3 of my Verizon Lollipop phones so dont believe its a Turbo 2 direct issue.

I guess I'll just be patiently awaiting marshmallow then!

Try this, idk if it'll help or not but under WiFi settings under keep WiFi on during sleep, choose only when charging.

Thanks, I'll give it a shot!

I've also read this cell standby time is related to WiFi and possible fixes are as follows. Turn off allow Google to scan for networks even if off, keep WiFi on during sleep charge only, LTE instead of global, and then go into recovery and clear cache. This is what I did and my cell drain is very low. Hope it helps.

Thanks for the tips - I changed all the settings but I'm having trouble getting into recover. When I try to launch from the bootloader I just get the dead Android with "No Command" displayed below it. Is there something I'm missing? FWIW I have dev mode on and unlock oem bootloader on.

I wouldn't turn on unlock boot loader this disables some security features and unless we have a way to truly unlock it. It's better to leave on. Dev mode doesn't affect drain issue at all. Here's link for booting into recovery.

Got it. Thanks for the help!

Mine drains fast while sleeping at home. In my case, the signal is poor so the phone has to crank up the radio power, draining the battery.

UPDATE: For anyone interested, the fixes suggested in this thread seem to have done the trick for me. After changing settings and wiping cache I am getting even better battery life (7-8 hours of screen on time up from 5-6 in similar conditions). This could, of course, be due to other factors - but hey, it's worth a shot if your battery is draining quickly!

Which lte did you pick? There is 2 options. Also how do you get into recovery? Thanks

LTE/CDMA

I personally have noticed that turning off mobile data when connected to WiFi helps. I have done this with previous phones

I experienced this the other day after spending the weekend in an area with spotty service. To fix all I did was reboot the phone.

Random Reboots and Battery

Hello
In few days i met with BLOD. I couldn't unbrick my phone until i get my heatgun, and fix it.
Now i have pretty similar problem but dunno how to solve it. Actually i am using PixelExperiece 30.12.2018 and phone sometimes just turn off and can't get up until i heat it up. Its turning off randomly but as i noticed mostly after pluging into charger or pc.
With battery is something strange because when im outside and has left 20% battery phone is turning off and after boot up i see 1-5%, does only changing battery can solve this problem?
Edit:
Tried On StatixOs, AOSP and AOSiP, it still get bricked but as i noticed only when screen is off.
Now im checking when AlwaysOn is enabled, if this wont work, will try with another Custom kernel and at the end on the FullStock
Edit 2:
Better but still shutdowning
