Cell Standby

Not sure if it's just me or not but has anyone noticed a cell standby issue too? My phone gets up to around 20% while I sleep which is weird because in my room I have four bars... so is it my device or does anyone else havt the same issue?

I did notice this myself. I would go to sleep with 95% and wake up with 70%.
So went to Settings/Accounts and Services/ and turned off Background Data.
Went to sleep last night with 97% and woke up this mornin' (nah na na nuh) with 94%. The gmail app seems to hammer the data. And I have found no scheduling within that app. Stock app has scheduling gonna try that and report back.
btw: with background data off and you go to the market it wants it on so I'll turn it on and back off after.
good day.

My cell standby floats around 11% at all times.
I find this to be acceptable.
My battery life has been satisfactory.

As long as this means my gmail/text/gtalk works automatically, I figure I may as well leave this off.
I don't use any syncing apps like Facebook, our anything like that.

I should have thought of this before. Turning off now, we'll see what happens. Also does anyone else notice flaky 3g connection mine is weird, a lot of the time my 3g bar just says 3g with a d under it instead of arrows and my signal fluxuates quite frequently verdict for you guys?

Ah, screw this.
Market doesn't work without it turned on and neither does the Yahoo Mail app.
That wouldn't be such a big deal if I wasn't bothered by Yahoo with a notification tray icon telling me to turn it on.

Use Gmail?

I use both and can't justify getting rid of my Yahoo just yet.

The d under the 3g bar is like a 3g "idle" icon if u will. But i have had a lot of issues with service and 3g. I rarely get above 2 bars and if i do its only for a short while. I lose 3g more often than i would like and get the dreaded 1x though it usually switches right back. I absolutely love this phone but the constantly having weak signal is killing my experience. Am i the only one struggling for service?

Nope, same here. Just left the Verizon store for the second time for this issue & connection errors with the Samsung email app. Their fix for this? "No one's having these problems that we know of. Let's try another PRL list."

I've encountered problems with the stock e-mail app on several Android phones.
There's seemly no answer to why it works and then doesn't work.
You'll find numerous threads suggesting you use K9, or some other 3rd party e-mail application for many POP3 e-mail addresses.
My main e-mail is a GMail, so that's a convenience for me.
I also use a Yahoo and before the Yahoo Mail app from the Market, I would also have trouble with the Android e-mail application from time to time.

According to the battery monitor, Cell standby is using a lot of my battery. Seems like this started happening more once I flashed the voodoo kernel and overclocked to 1.2 GHz, and put the "kickstand" case on my phone. I'm going to run fora few more days and see if it's consistently bad, and if so, I'll try taking the case off first to see if it gets better.
For instance this morning it says Cell standby has used 33% of my battery, it's been on for 11 hours, and I haven't charged in about 6 hours. I've dropped to 62% battery capacity, with the screen mostly off and not using the phone in those 6 hours. It says my time without a signal is 23%, I've seen it as high as 40%... I don't get very good signal in my apartment, but this seems wayyyy worse than it should be. I did a *228 update yesterday but that doesn't seem to have helped.

thanks, was wondering why battery drop 20% even when i set to airplane mode before bed.

Sounds like a background process is hogging. See this post. Hope it helps find your problem.
good day.

When I wake up my phone, it's connected to 3G, but I am on wifi.

Anyone else having this problem? I don't remember having this happen on my MT3G.
It's really eating up the battery.
I am on JI2, and I never experienced this until last night after using Odin.

you have to change the wifi sleep policy in the wifi settings. Got to settings, wireless networks, wifi, then press the menu button and select advanced.

OMG! thanks, you're a real life saver.

Sorry to bring up an old thread. I have it set to never sleep but it still does. Any ideas? Seems when the display times out, it switches off wifi.

I have wifi on all the time at home and it's set to never sleep. Sometimes I see both the wifi and 3G icons. I know my wifi signal is strong, so no idea why the phone sometimes also seems to need a 3G data connection. One example is when I test GPS at home the 3G icon will pop up briefly. Another is following a reboot. But I see other times as well, and sometimes it stays for quite a while, but eventually goes away. I wonder if perhaps some ports get blocked by my router and the phone uses 3G communication to get around it. Bit of a mystery, but I don't see any other negative symptoms.

Here is something I have experienced. This is regardless of what ROM I am on.. Stock, Bionix, whatever...
I have wifi turned on at work. Sometimes I would see wifi and 3g on at the same time.
Now today, while texting, I noticed that my Wifi connection dropped to nothing, and at that point my 3g kicked in, which I expect it to. But when my Wifi reception kicks back up again, my 3g didnt turn off. I turned off Wifi and turned it on again, and my 3g turned off.
Anyone else getting the same experience?

samnada/ELStiko, That's what I'm really seeing too as I thought my wifi was just going to sleep.

I'm pretty sure my wifi isn't going to sleep. The wifi icon is on all the time with at least 3 bars. My cell signal is definitely weaker in my location. So, if it's seeking the strongest signal my wifi will always win.
Besides the possibility that my router is blocking some ports the phone wants to use, there's also a possible security issue. I know at one point the TMO My Account app would force a switch to cell communication versus wifi and I believe it was due to security concerns. Maybe some apps do the same thing.
I just did a GPS test, got a lock, stopped the test, closed the app, and the 3G icon stayed up for a couple of minutes then went away. Just one example.
Does seem odd, but I've just assumed there's some rational explanation. Could also be a bug...

your lucky you wake up and you have 3g. i wake up my phone is always on edge. lol

leaving 4G has always bogged my CPU

Have you guys ever noticed your phone slowing down as it constantly switches between 3G and 4G? Living in Austin, I probably make the switch a few hundred times a day, depending on what building I'm in, and where my phone is sitting.
There are plenty of times where I pull my phone out of my pocket, and it's very warm, and running horrendously slow. I typically notice the 4G icon, so I disable it altogether. Usually within about 30-60 seconds, my Evo is responsive once again. I have used every stock ROM, and about 6 custom as well. All behave IDENTICALLY.
I really have had only one instance where 4G was useful, and that's when I was at a restuarant, and I wanted to tether my laptop. I was able to get a solid 4G signal, and it seemed to work great. I did find out, however, they had free WIFI, like almost every business does these days.
Not so sure I'm really sold on the 4G stuff, even though almost everywhere I go in Central Texas has good signal. It seems to waste far too much CPU as it switches back and forth, enabling/disabling radios, or whatever. If I'm in Dolphin browser, and it switches radios, the phone appears to lock up sometimes... quite annoying... happens all the time.
Anyone else with similar issues? I know most people aren't even in 4G areas though.

Well in general I noticed this cpu spike on my sense roms even when it was turning 3g back on after leaving a wifi spot. I really blame HTC's inneficient code, since CM6 handles this so much better. I did try 4G out in my area and thought it was better on my cpu than 3g was though.

After you use 4g, you need to reboot your phone. The 4g icon may go away but the phone is going to keep searching for the 4g signal. Known issue/bug. You can ssearch the forums and find lots more info on it. Free app called alogcat will show you this by conintuing to try and connect to winmax.
I live in Austin, too and use the 4g toggle quite a bit, especially closer to town, while at concerts or football games.

That explains why when I leave 4G on regularly, I have to reboot my phone at least once a day from slowdowns... If I leave 4G off, I tend to last almost a week before I get frustrated enough to reboot.
Really disappoints me, and I was hoping I was an isolated example. I had done several searches for this, and didn't see any results. I guess because not many people have 4G, and those that do probably toggle it on specifically for use when they are in a 4G area. Seems to me that 4G is only useful when you are sitting still... if I am in the car and I leave it on, my phone get sluggish as hell, and my battery can be dead in under an hour.

I believe the bug only occurs if you have a 4G widget on one of your home screens. You may be able to remove it and turn on via settings as a workaround.

Correct. Don't use the widget to toggle 4g. Go into settings and turn it on that way and you wont get the lag.

I had a ROM a few weeks ago that didn't even have a 4G toggle... I think it was AOSP. Didn't like it much and came back to Sense-based. No effect on the CPU bogging.

I live in houston and not in the city, I get this every day....i stopped using 4g a while ago...it'll get better with time though

Only turn on 4G when you are actually going to use it than turn it off. Most web tasks do not require 4G and it will improve battery life.

theres a couple guides out there for editing your 4g in and out times, signal requirements log in delays, ect. those will help big time, and you should be resetting your phone once a day anyway for good usage, also it helps to if your using 4g, turn off the mobile network because its pointless to run both radios at the same time [helpful if you have myns with the data in the notifications menu for easy chaning]

Can you confirm that turning off the mobile network from the power-button drop-down menu actually does anything? On my phone, when It detects 4G or WIFI, the 3G icon disappears for a bit, then turns into the new one. That leads me to believe that it automatically does that for us...

I use 4G every day. I have "mobile data always on" set to on demand, so when I turn on 4G via the Extended Controls widget I use, 3G automatically turns off. Haven't had any phone slow down since I started using this method. When I turn 4G off, 3G automatically restarts, so one or the other is always on. I keep 4G always on at home, and only turn it on while out if I'm watching using large amounts of data.
At some point I made some changes in how long my phone will try to stick with 4G when there's a strong 3G signal, and that helped with streaming music/data while on long drives.

The only time you should see CPU usage is when the radios are toggling on, and off. Also when you turn 4G off, yes if you look in logcat you see that WiMAX is doing something but that's about it. IIRC it is checking the status of the 4G radio to see if it is on. The radio is off though, verified by monitoring the current drain in almost real time. The 4G radio draws about 200-300mA itself. The "4G Toggle for EVO" app by Jason Calhoun (see Market) so far has given me the least amount of hassle of the 4G widgets out there, and most of the time I don't have to worry about turning off 4G after a reboot.
On average with my current configuration I draw about 254mA (3G /display @26%/doing nothing), 188mA on WiFi. The lowest I've seen was 89mA (just coming out of sleep), and the highest I was ever to draw was 996mA (everything on, turned up, playing Angry Birds).

Under 4G settings make sure network notification is unchecked, if not the phone is forever scanning for a signal, especially if you're toggling bad. If you have it unchecked even when you use the widget it will only search the initial time when you turn on the widget. Can't say this will solve the issue, but at least stop the phone from continuously scanning for a signal should help. You can only uncheck network notification while 4G is checked. Hope it helps cause i'm in the centex area also(Waco). It helped for me when told to me by EVO owners.

I've also noticed my Evo seems really sluggish when 4G is on. Like, to the point that I always leave it off, because it makes my phone barely usable sometimes when it is on, even when I am standing right next to the 4G tower. I read through here and I'm going to try removing the HTC widget for 4G from my home screen, maybe that'll help.

But until/unless you reboot the phone, the WiMax continues to check the status of the 4g radio. So that would make the phone sluggish. Even with no toggle on a home screen or any screen, just doing it manually, when turned off it keeps scanning. Right Thats what alogcat shows until the phone is rebooted.
I have turned off 4g and gone about my business and been fine - went almost 30 hours on one charge and had 4g on for about 2 hours of that, so it may not be a major battery drain amp wise, but it appears to continue to scan even when turned off.

From a 2-day trial I can definitely say that my phone seems much more responsive since I removed the 4G widget. I replaced all the HTC radio widgets with the stock android one (which, of course, doesn't have 4G) and my phone seems very responsive. At the same time, I turned on 4G via the settings menu and I've left it on. It seems to be working well.

battery tip,

Here is a battery tip
Disable Data on ur phone, If ur not surfing the web (turn on data when u need it )
Calls and Text still go thru
Hold down power and the menu will come up then click on deactivate network
OR
This also can be done in extended controls Or Quick Settings
MAKES A BIG DIFFERENCE !
so far i got
14h 44m unpluged and i have 46% Left on Axura 2.2.5.9 ( i knoe 2.2.6 is out i just find 2.2.5.9 better)

Wow. You're a genius! Haha. This has been known for awhile due to obvious reasons. In fact there are apps that will turn your data off/on whenever your screen is sleeping/awake.

i knoe but do u really need data when u make a call ?

No, just turn it off manually. Those automatic apps are pretty pointless imo. You don't use data every time the screen is on, they just use more battery by constantly switching and giving the user no freedom.

dunno about anyone else but when I push send to make a call my data icon turns off and disappears until I hang up.

I don't think GSM supports simultaneous data and voice.

I think powering off the phone when not making calls will save even more battery.
Seriously, I use my phone for a lot of things that require background data. Seems silly to me to turn off something critical for me using my phone just to save some battery.

so far on nero 5 i havent even reconditioned ( im going to do it anyways later) , but its given me over 16 hours of battery, and thats all i need, i just need 10 hours max, from the time i wake up to the time i go to sleep, if it can give me that im good.

Hey if u deactivate ur phone it will save your battery life.
Seriously though I am using juice defender on my evo and it basically turns data off while ur screen is off. It has worked pretty well. It was off the charger from 730am yesterday till 11pm last night and I still had 55 percent. Of course I worked all day and my phone saw very little use yesterday.

issue regarding constant network switching.

OK got my galaxy however got some concerns regarding the constant network switching from H to 3g. I know am in a area of very good network coverage so that is not the issue but I have noticed my phone keeps switching between the H and 3g. It seems to change to H when the a connection is required for instance now as am typing its on 3g, however when a data connection is required it then changes to H, however as am typing it sometimes just switches to H even though am not using the data connection. I can probably see the logic here for the phone to switch to H when a data connection is needed but am thinking all this constant switching must somehow impact on the battery. Av, always used the app by Philip Mangelow the network app, to set the phone to gsm auto prl, which apparently is the best setting to use as it stops the radio from constantly searching for the network, however the same app, won't work on galaxy. Is their any code or tweek required to enable gsm auto prl.?

Yup, this happens on all phones I have( DHD, Nexus S, SGS2).
It will show H or H+ (if you have HSPA+ coverage ) when its actually downloading /uploading data. There was an article on the web that explained why its done. I will search for it again as I didnt bookmark it. But this actually increases the standby time of the phone and reduces battery drain.

Cheers matey looking forward to seeing that article cause have used quiet and few android phones and never had this before, and if it's good for battery then fine but would still prefer to set that gsm auto prl setting so if anyone has any suggestions please.

Exact same problem here! the strange thing is my SGS1 was always on H.

getting same, mine goes on 3g then changes to H, I think this is draining my battery, i full charged phone overnight and took it of this morning on 100% i went on XDA app for about 20 mins and i used 6% battery life just using this and nothing else. that to me seems like a huge drain

I set a toggle switch to turn off data when not needed? This may help in battery life, but im not sure why it keeps witching from H to 3g?

I suppose its not a big deal i guess, it doesnt seen to affect my battery life.

ok, surely this cannot be good for the battery, i have noticed, whenever, i unlock my phone, it shows H high speed, but when unlocked it goes into 3g. Surely, the phone is supposed to be on 3G when screen of the H, when i turn screen on to use it?.
