Interesting battery consumption with wireless

I thought I would share my recent findings with all of you as it appears battery consumption is a hot topic. First of all I've never had a probem with battery consumption on my DHD, I've always been happy and I'm still happy. This is just an observation.
In my house I have a good wifi signal everywhere except in my bedroom, when I'm lying in bed it can lose connection every now and then, this has not really been a problem until 2.3. It's as simple as this, if I leave wifi on with a fully charged battery next to my bed the next morning there is 10-15% battery left, if I turn wifi off then the next morning there will be 75-85% battery left.
If I'm at work with wifi on all day even though it's not connected to a wifi connection when I go home there is still at least 60% left. Clearly if you leave wifi on connected to a network and the signal drops out every now and then or if the signal is poor expect your battery to be exhausted in no time. Leaving wifi on is not the problem, well in my case it isn't, it all depends on the signal strength of what you connecting to.

Same here . and if you have a good wifi signal the battery life is much much way better than using 3g connection

This is normal behaviour, when wifi is on it will try to reconnect if it loses network, hence in your case it is continually reconnecting to the wifi and draining the battery, if this is a new issue with 2.3 it may be curable by flashing one of the older radios as it may be an issue with the new radio?

same probllem
i have the same problem with my DHD, i have stock rooted rom 2.3.3, and my bettery is draining at an alarming rate, cause it always trying to reconnect to wifi network. but the main prb is that wifi signal is strong, as my laptop has excellent signal, but my phone is strange, sometimes it has full signal, sometimes it drops and completely disconnects from wifi. as i move it arround a bit it reconnects. if i flash an older radio will it resolve this prb? and how do i flash an older radio?

You need to be Radio S-OFF to flash the radio, but if you didn't have the problem previously just try downgrading with one of the RUU's listed here
which will re-flash the older radio which should put you back to before the upgrade, a work round for now is to turn wi-fi off when not actually using it at least for now. BTW this problem doesn't appear to be present in the GB custom rom's so must be some tweak by HTC that has gone awry.

i've searched trough the forum and found some answers. htc made gb drop wifi connection when the signal drops bellow -88dcbl. cusom roms have a drop limit of 101dcbl. i was on stock (only rooted) GB 2.3.3 . I've downloaded kingdoms custom rom v1.7 intalled it but i get blank screen, only wallpaper, and can't get any further. like unlocking screen and getting in to the menu. would you recommend a custom rom that's most stable for DHD? btw my phone is rooted and all OFF. i flashed like... 4 radios all the same problem, so... stock roms are no good.

Do not need to change a custom ROM, and there is a wifi connection fix (decrease the drop threshold) flashable patch zip.
Sorry I have forgotten where is it, but I think you can search and find it among the forum.

CM 7 all the way for me, and if you must have sense ARHD is supposedly very good

Use wifi timeout app so phone can sleep properly, without significant drain.

[30/09/11] [Q] [DEV] Reception problems during movement and in general

Hello everyone,
Since the beginning of the Android period, I've been experiencing reception problems, as well as a few friends of mine. The phone is continually searching for signal and losses it quickly, jumps from HSDPA to other means, and also has the problem of regaining the signal after going through a tunnel etc.
I am not a developer myself, but was wondering if anyone else was experiencing the same problems and if there is anything to be done about it.
I know there was a slight fix introduced not too long ago in Tytungs kernel, but for me things still pretty suck.
If you have something to say about this, please do. Otherwise, a mod can handle the positioning of this thread. No need to start flaming if you have nothing to say.
All Hail XDA!!
Cheers,
Chovav

Thread reported to forum mod, Why don't you realise even after placing [Q] in the heading that you need the Q&A forums.
As for your concerned problem, i havn't faced that till now except for the fact i have data drops seldomly.

I have the same problem. I've tested several ROM, radios, Magldr clk...
I always use the *#*#4636#*#* trick. But I always have to return to 2G only.
I think that there must be different kind of hardware that avoid getting a decent signal level.
I tried the Probable Hardware Fix For HD2 Poor Signal too. I have better reception but no as solid as with 2G
I love the phone but when I use only 2G I want to cry (almost everytime).
Thanks in advance, Paco

Just something I would like to throw out there, I also have reception issues on ANY rom, but its occurrence seems to be like the original iPhone 4 came out, terrible reception if you squeeze the whole phone with your hand. I prove that theory by doing that in my room, if i dont touch the phone (just the screen) and browse the web, I do it with full bars. But as soon as I pick up the phone and browse, it will drop very quickly to 1 or no bars (from 4). See if you can trial this yourself, put phone down and browse web, and then hold the phone and try it. See if that makes a difference. Does for me.

There was a thread a while back about this and it showed a screen that you can get to that shows how long you have had signal and I remember looking at it in mine and it showed that I was without signal at least a third of the time the phone was powered on. I don't remember how to get to it any more or I would show you a screen shot of it. I have constant full bars of H where I am and even not moving the phone still shows this same behavior of dropping connection to the towers.

Weak wifi signal

Not sure if anyone can help.
For some reason, I noticed a couple of weeks ago that my phone alerted me as normal for some app updates, but when I checked them, practically every app on my phone needed updating.
Shortly after that, I was in the bedroom browsing the net and noticed that the wifi icon was only on the dot and floating up to about 1 or 2 bars - always used to be full.
Sat here now in front my router and its was the same, although strength is showing good and 65Mbps. My partners Desire S is showing full strength along with my work iPhone. Was also in the bedroom last night and it was hopeless, kept dropping out and unusable, although iPhone again was full - never used to be like it.
As far as I can see, the software hasn't changed
Android 2.3.5
HTC Sense 3.0
Software number 3.12.405.1
Hope someone can advise

Pull your battery cover off and clean the contacts, possible it's just a bad antenna connection.

yep thanks Darunion.
I was just logging on to reply and say that I've done that and seems to have done the trick.
Stoopid phones lol

Yes, I had same problem with, wifi signal. I pulled battery corer off and cleaned the contacts. Since then everything is fine.

HD2 weak wifi signal ALWAY!

I have tried this fix, it still doesn't work.
http://forum.xda-developers.com/showthread.php?t=1190180
Raising the top right 2 flaps, according to this image. http://forum.xda-developers.com/attachment.php?attachmentid=668981&d=1311865226
Basically I raised everything.
Any idea what else I can try?
I am using 2.09 HSPL

do you have any objective measure of how weak your signal is?
mine isn't so great either; certainly less than a friend's iphone.
if you go into wifi/ advanced (in winMo), you get a signal quality bar. Mine only registers 100% when i'm literally within about 750cm of my router. beyond that, it drops to about 80% for another 2 metres, then drops to 60%.
i've done the same test on my old tytn II winMo phone and it's about the same, so maybe that's just how it is.
what this means, is that free wifi in bars/ hotels etc. mostly work OK but can be marginal where others are getting a good connection 100%.
i haven't tried taking off the back to bend the contacts up yet as I remember the royal pain it was the last time I had to open my HD2 (to clean a fingerprint off the inside of the lens cover left by a HD2 tech after an RMA).

Perhaps test a couple of the favourite radios & see if get any better wifi reception.
HD2 wifi is not the strongest but if hardware & firmware up to scratch it normally usable even on low registering signals.
My HD2 signal compares about same to a Desire, Topaz & Touch Pro.

my WiFi signal is about ok.. Though Network signal ain't that great.

I have bad wifi signal strength too My friend has 3/4 bars in his LG Optimus One P500 and downloads a torrent with 200kb/s and I can barely see the connection with 1/4 bars and keeps disappearing.
I haven't tried the antenna fix though.

[Q] GPS suddenly almost non-functional? Is this possible/software fixes?

Hello,
Recently noticed my GPS barely works. If I'm out in an open field it can get medium strength locking from satellites in GPS Status. My wife has identical phone and gets the type of GPS signal I would expect to get. Side by side my phone simply cannot get much. Indoors forget about it. It use to be so good. I certainly have dropped this phone here and there but in the past it never influenced GPS. Is there any possible software/firmware side of things that could be causing it? I may have installed apps or updated apps but I didn't do any tinkering with the GPS specifically or with flashing roms or whatnot since this summer--and it worked fine then after any tinkering---this is a recent development.
Can anyone provide any ways to troubleshoot this? Possible the GPS chip is partially broken? I mean.. it can get signal.. just piss poor and struggles mightily. Almost can't get it in the car, loses GPS lock under tree cover, etc. Very temperamental.
Seems a little bit like 4G has also degraded but a little more unsure of that.

bump! Any help, methods to trouble-shoot between hardware/software. I tried to erase modemst1/2 see if that would jog anything, no effect.
thanks

It's freaking Christmas, just buy yourself a new phone
Sent from my HTC One using XDA Free mobile app

tempting..and I will in a few months when my contract is up. But this was a spectacular GPS for navigating in the backcountry with downloaded maps. Would love to be able to retain that use after it is no longer a primary phone.
please, any troubleshooting suggestions would be appreciated!

I've had very few problems since switching to Waze and SlimKat. It was horrid under CyanogenMod no matter what I used.
I had been having similar problems under stock KitKat. Here's what I noticed, maybe something will help you:
Resetting aGPS data and re-downloading wouldn't help.
Sometimes GPS would never give a location with plenty of satellites locked to. I modified some build.prop stuff to give me a horribly inaccurate lock in these cases. It was also usually fixed with a reboot.
GPS status would show TONS of satellites overhead, but never be able to lock on to more than one of them. Making sure I had wifi turned on (even if I was in the middle of nowhere with no wifi signals) eliminated this problem.
Something would randomly disable the GPS while I was using it, when it turned it back on a short time later it wouldn't lock (usually due to one of the above issues). I eventually concluded it was how Google Maps and some of the new location stuff works these days. I assume it's trying to save GPS power, other programs were much better. Solution: F Google maps; I only use it as a fancy yellow pages these days. I had stuck with the old, old, version (that still supported Latitude), but had to update when I went to KK and that's when my problems started. This is just another thing that pisses me off about it. I use Waze for navigation now (though I miss lane guidance and using my own text to voice software).

Some GPS bugs can be resolved by flashing to stock firmware, getting a GPS lock and while locked on GPS, reboot straight to recovery and flash your new ROM. After doing that once I have flashed (too) many ROMs with no GPS locking or accuracy issues.
Also make sure your GPS is set to high accuracy and not battery saver.

ezdi and kronik.. thank you for suggestion. unfortunately to no avail even with full reset.
sometimes really seems like my general phone reception, wifi, gps, and data (1x/3G, 4G) are all haywire. Certainly they all work. But the data is never as strong as it should be. Often seems like it needs to be jogged (airplane mode on, then off)/dead areas--while my wife's phone is solid (same razr m but rooted with unlocked BL and stock rom). Likewise on the GPS. it can certainly find and lock satellites but in GPS Status only ever reach 'half bar' strength green.. they use to be able to lock multiple sats at max level.
It's odd...we are talking about the 'radios' of my phone, no? or mostly? I generally consider digital electronics to either function, or not. That they function at all--can receive pings from a satellite, can transmit data to and from towers... tells me the electronics are functional and this is software side. UNLESS there is some radio hardware component that is an amplifier of sorts. If that electronic was broken it would make sense why things function but appear weak/spotty.
thoughts?
aside from my contract being up in a month and what the hell next phone I should get from verizon... haha. But no I'd love to get my phone back to where it was and have a dedicated backcountry/hiking/skiing GPS... which it wouldn't be capable of now (it was..when it worked).
Cheers
