[Q] Crazy high cell standby killing my battery life?

Help!
I'm running the 81xx firmware on a direct-from-dell unlocked Streak.
My battery life has so far been abysmal, and looking at the battery usage screen, my cell standby is usually over 60% while idle is less than 20%, everything else like 2%. This isn't from weak signal, though; I am in a well-covered 3g-only area and my phone has reported only being disconnected about 4% of the time.
Another strange thing is, my data indicator is constantly switching between the H symbol and the 3g symbol.
Anybody know what's going on?
It might be that while you are well covered for 3g, you are marginal for HSDPA and that constant switching back and forth is using your battery. I have not tried it but have a look and see if you can disable HSDPA in settings somewhere and see if that helps.
i'm usually around 40% cell standby.. do u have any task killer apps installed? although people think those are useful they usually do more harm then good.
I have the same problem, and I used another Android phone in the same location (hence same cell coverage) with no such problems. I just took my phone off the charger and had the display on since then non-stop. Cell standby used as much battery as the display!! There's no way that is appropriate.
I'm running build 8102, but it was the same with 6941 before. Can't tell about 1.6 as I bought my streak used with 6941 on it.
What Android version are you guys running? Maybe we can find common denominators.. :/
Edit: here's a screen shot of the battery usage after a while off the charger with the screen on constantly:

Do you think your antenna might be loose or defective?
I can't imagine the antenna to be loose really - but who knows, I bought mine used. If so, I think there is a signal strength value in " about phone" somewhere, no?
What signal strength are others getting? I'll post mine later, I'm on airplane mode right now so that I get some battery life.. :/
For signal strength, I am getting -75 to -95, and 9 to 12 for the two values while riding the train (not subway).
It also appears my battery life is quite good when my phone is in standby and not doing anything... the problem seems to come from net browsing or anything else that uses an active connection... Just browsng XDA is taking about 2% a minute!
Oh and my android is the 81xx 2.1 version with the modaco tweaks
Sent from my Dell Streak using XDA App
I had really high cell stand-by too. then i installed juicedefender, now my cell standby is down to about 29%.
I think the main thing is that it disables data connections while your screen is off and only turns it back on when the screen is on and unlocked. It also has a setting where it enables data connection periodically to allow background syncs and whatnot.
I'd recommend you guys give it a go, it had almost doubled my battery life!!
Mine shows,
cell stand by 50%
phone idle 44%
it seems quite common on the streak as I read in all the forums. I am on 2.1 stock rom? what's 1.6 like?

Battey drain due to radio?

Hey, I am trying to figure out why my battery drain is so high. Part of it is the display (trying to work on that too) but I see that my "phone signal" is quite bad. I have a feeling that this is draining my battery.
I have attached my battery stats. Do they look normal. And does the phone signal look normal or below normal. I think it is worth noting that I almost always have 4 bars of signal so I am not sure whats going on. I use my phone in Canada on the fido/rogers network (i believe it is the same as At&t in the states). Is there another radio I can flash or something if this is not normal (which will still work with my phone/network)?
Thanks a lot
Reports are that using 3G a lot drains the battery immensly.
Try switching to use 2G only and see how that affects your battery life.

I dont think it is worth it to pay $30 a month to use 2g networks. I will try to turn off the 3g radio when on wifi though. And maybe only turn on 3g when i need it. As for the phone signal bar. Is it the same or worse than what you guys are getting?

It already works this way. Wifi is going to be your best bet to lessen drain if available (both in standby and when using data - just make sure you have the sleep policy set to never).
If you have poor signal you are going to murder your battery - no way around it. The radio will boost power (Gain is adjusted automatically) in an attempt to get a better signal - and constantly search for a better one. So if you are bouncing between no service and 1 bar or even with just a weak 1 bar signal you are going to see atrocious battery life. There's not much you can do there except potentially switch to SIP in those times if you use a SIP provider.
If you are sitting with 4 bars then you should be seeing decidedly better battery life. What is the actual time the display was on in that screenshot?
I use 3G and its fine. What radio are you using?
the choices are: JK8, KB1, KB3, KD1
you can find them on the dev forums

that looks pretty normal for that kind of usage. id say that you were a moderately heavy to heavy user.

I usually have about 3-4 bars. The time on for the display was probably just over 2 hours (judging from what it is now).

I have KD1, how does that stack up?
also, I am using netarchy bfs kernel if that matters.

I agree. you're a pretty heavy user So far different radio doesn't drain battery, but only the difference of data connection speed cap.

Yes I do love android (been tinkering around since the g1). I do realize that I am a heavier user than the average person but it might also be that I recently got this phone so I am using it more.
Aside from that, does everything else seem normal?
"Android System" should not be taking such a high %. It should be about 1-2%.
There is (was?) a bug that causes high cpu usage (and shows as Android System) when wifi is on, but not connected to a network.
Another thing I can think of and is something I've experienced, is that sometimes you get an IP address from the mobile network that has a lot of noise, that is, it's an address someone has likely used p2p programs with and there are lots of connection retries. You can see it because the green arrows don't stay dark for more than a couple of seconds, and it kills your battery quite fast. Reconnecting to get a different IP address is the only solution...
Also, bluetooth may be a factor...

Blutooth is always off unless I need to use it (which is rare). I am not sure how to make my mobile network connect to a different IP adresse, would turning it on and off do the trick?
Being in area where there is low/no signal also causes my battery drain to increase by a lot! Which sucks cos where i live i get either 1 or no bars of signal.

[Q] Wifi signal

I was high heavy problems with wifi signal...
Even after making a "windsurfer" to redirect my signal it still was unpleasant.
So I took a battery size foil paper and put it above the battery.
Indeed my signal got better. It is not stable (I don't get 3bars all the time, i get mostly 2 floating around -80-70 dbm and sometimes 3 bars) but its not getting dc all the * time.
If anyone could try this to see if it works...
Also, is there any harm doing this?
When the battery heat up, any damage?
Thanks!

900f reception and battery life

Hello, so i have had an internationally unlocked 900 f for a while now, and i am currently on the latest phoenix rom with ktoon kernel, and i have noticed that in canada, the reception is always poor, 1-2 bars and it might spend a couple of hours without signal at all, and i believe it is why my battery only lasts for 10 hours with only 1 hour of screen on time.
Can anyone help me fix this please, i have tried only gsm, and wdsm( or whatever is in the options) and lte, and they all yeild around the same except lte, which is almost nonexistent reception. I have went through all my wakelocks and they seem harmless, at the 10% level of batter, i have 5 min wake locks, whic seems fine
