When I check what has been using my battery, I see that 32% has been used for "Battery used by cell radio". Does anyone know what that means? Does it refer to the FM radio? Because I made sure that was not turned on.

How can I turn off "Cell Standby"
Battery used by cell radio?
I recently purchased this Tablet cum Phone Device (Asus Fonepad) in India. I found this device very impressive with decent battery backup along with great standby time. Everything was allright. In morning I found heavy battery draining during standby.
Next day I uninstalled that Black market application and Uninstalled Exdialer with all downloaded themes. I got full signals and everything was working fine. But the Battery Drain in standby remain same. I observed the situation till next two days. I searched to forums and did following things:
1. I made factory reset to my fonepad. which was haviing 4.1.2 Android after updating through OTA. Which remains same after Reset.
2. I didnt install any other applation
3. I turned of all battery comsuming services like GPS/ Location reporting/ Data/ Wifi/ Uninstalled Google Play Service Updates etc
4. Installed Wakelock detector, Better Battery Stats etc All are showing that phone goes in deep sleep no prblem but Wakelock detector show that Cell Radio wakes up so much time when phone is on sleep mode. Default Battery monitor of Android Showing "Mobile Data" as most battery comsumer.
One thing I want to mention here the device is supportive to mini sim only. I was not having mini sim so I went to market and mobile shop keeper cutted my Sim to adjust into that slot and it woked. I was using same sim from Day first. It's Vodafone INDIA.
I have not rooted nor flashed anything from my fonepad. I am reached to the conclusion that There is some problem with Exdialer installation and applying new/old theme combination to it which made me device with no signal. And now The Cell Radio has been changed which is attempting to achive something in standby mode. Which is causing heavy battery Drain. Standby time is reduced to almost 15-16 Hrous
I've ported a Hero ROM to a HTC Magic.Here's my problem:
Problem: There's a great battery drain when you're connected to the network (no data but just mobile network for calls/SMS)
Ported ROM: Sandwich Deluxe 4.0 .
Original ROM: Hero ROM
Kernel: carz-2.6.34.4 (fast and stable)
The mobile network drains battery.I'm not in a low signal-area. Everybody who uses the ROM has a drain.I'm using a 2.x.x instead of a 3.0 kernel for an ICS ROM, can it be that this mismatch creates the drain?The phone displays a singal strength of 0dBm 97 asu. (Not normal?)
What doesn't cause the problem? In airplane mode there is no drain at all. So it is unlikely that some apps causes the drain.Wifi, GPS, sync, ... are all disabled.
What do you expect from xdamembers?
- Confirmation if the kernel is the issue of the drain. If not, I would like to know which files (in ROM) are responsible for network signal.
Is it possible to turn off JUST the cell radio? If so, how?
View 21 Replies View RelatedI've read all the threads I could find in here about turning off the cell radio but none have addressed this particular configuration. The reason I want to do this is because I don't use my Incredible for talking, I just use it as a computer. For talking I use a cheap little "dumb phone" so to conserve battery while i'm out n about all day, i would love to be able to have the cell radio off while 3g is on. If anyone knows of any way/app to achieve this.
View 8 Replies View RelatedI would like to know if I can turn off the cell radio on my HTC Magic but keep the WiFi on. I live in an area where the cell signal is very poor for all carriers (I'm with Rogers). So when I'm at home I have my phone set to call forward to my landline phone and use WiFi as my connection to the internet for e-mail, MSN, etc. I know you can put the phone into "Airplane Mode" but this disables all radio including WiFi. The reason I want to disable only the cell radio is that my phone is constantly losing and reacquiring the signal from Rogers which eats up battery.
View 6 Replies View RelatedIs there a way I can get access to the following information from the cell. I know that it uses a Qualcomm MSM7201A chip. I know qualcomm unleashes a boat load of information such as: Pilots-Channels PN offset Neighbours Searches PN Codes Power Control-TX and RX Slot DRC Signal Noise Ratio Carrier to Noise Ratio Energy to Noise Ratio
So the question is can I get access to all this information and are there APIs from Android that I can use.
So far the closets I have come is in telephony/PhoneStateListener telephony/NeighboringCellInfo telephony/CellLocation telephony/TelephonyManager
When I am at school I can barely get a signal. I constantly get notifications for going in and out of service and it's MURDERING my battery! So I was wondering if anyone knows how to completely disable my cellphone usage WITHOUT disabling wifi?
View 10 Replies View RelatedAnyone know if there is a way to have the Nexus automatically go to Edge when WiFi is enabled? Seems like that would be a smart way to try to maximise battery life...
Maybe it's already doing this, I don't know, since the WiFi symbol blocks the 'E' or '3G' symbol...
But if it doesn't - I propose it as a feature for a future update...
Is there a page that allows Nexus users to propose features? iPhone had this way back...
What uses more battery, Wi-Fi radio or 3G Radio ? I'm using an Eris.
View 7 Replies View RelatedI charge my evo while I'm sleeping. Last night I went to sleep with it at 100% and woke up 10 hours later to find that I had lost 50%. Battery indicator told me that it was 48% cell standby and 48% phone idle and only 2% Android system. Is this usual? I didn't know just leaving my phone on the table would kill so much.
View 5 Replies View RelatedIm trying to figure out the consumption issues with my battery and cell standby. it is currently responsible for 39% which is at the top of the list just above phone idle. what really concerns me though is my time without a signal is 49%!! but everytime i look at my phone it has 3bars! how can this be? and im assuming this is whats killing my battery? it should be noted that i dont think i have the "bug" others seemed to have.
View 5 Replies View RelatedI was just wondering if anyone had the same issue as I do, with about 44% of my battery use coming from the notorious call standby.
I heard some speculation that this is akin to the issue with the Eris 2.1, so it would be solved by the Airplane Mode trick, but I have not found any results favoring that remedy.
A cell phone is a transmitter just like a radio tower, and higher power is required to send the signal farther. Every modern cell phone automatically adjusts its transmitter power based on reception. Fewer bars means faster battery drain when you are using your phone. Switching to 2G will not necessarily save battery. If you have a 3G tower nearby, then your battery will last longer. And if you have a spotty 4G connection, you'd best plug in, or don't use it. However, given equal signal strength, a 4G signal is MORE efficient per byte than 3G.

About 3 months ago something changed overnight and my battery went from 20 hours to just a 6 hour battey life. After a week I did a factory reset but the same. Took it to HTC in Saigon to be tested but they said no problem YET when I was there battery lasted longer. The problem was in only in Can Tho where I live UP to this month when the problem is now in Long Xuyen. I travel, to Cambodia a lot and usally when I leave Can Tho Battery life is better. I am now in Cambodia and battery life is 40 hours on a CamShin SIM. For a test in Can Tho I went to a phone shop and used a Vinaphone SIM for an hour and got a 40 hour life. This is a joke! Is there any application that can control the Radio or at least tell me what's going on? I tried a few but they do not say anything different between Vietnam or Cambodia. MobiFone did something but refuse to tell me anything. Back of my G1 with 1.6 is cool now but in Vietnam back of phone is very warm. Tried to reflash the Radio but phone will not let me. I rooted but still it will not let me. think I must load a new recovery program.
View 4 Replies View RelatedI'm about to retire my trusty old Epic 4G and whats the best way to store my battery on it. I will be removing it but I'm not sure whether I should store it fully charged or half way charged. If I remember correctly, I read somewhere that you should store your battery with 50% charge for it to have some life if you ever need to use the phone months or a few years time. Storing it fully charged can pose a threat due to the battery blowing up?!?! Not sure if this is correct or not. What to do to preserve your unused batteries in your old phones?

I get horrible battery backup because of cell standby which takes 50%-60% battery...How can i reduce it???
I just have 13 apps intalled namely xda,dolphin and uc browsers,jetaudio,titanium b,es file ex,es task mgr,link2sd, lucky patcher,soundhound,holo plus and dictionary
I tried doing the Airplane trick...I am not sure this is the 50% issue others have mentioned because when I go to view my battery statistics, it doesn't show the 2 lines of information like it did before (i.e, 50%), but my phone idle and cell standby are Both hanging around 36%...seems kind of high in my opinion.
View 3 Replies View RelatedJust yesterday my phone was getting more than 14+ hours of battery. Now it's draining really quickly even when I'm not using it (I left it on while I was asleep). It's not facebook because I already downloading the fix and rebooted. My "time without signal" is 0% so I don't think that's the problem. I did download Quickpedia yesterday but a quick search tells me that's not the problem either.
The only other thing I did differently was switch from ADW to LauncherPro yesterday, but if that was draining the battery wouldn't it be under Android System and not standby or idle? Regardless, I switched back to ADW just to see if that works
First off, I read these forums like every day for 2 months (nearly drove my wife insane!) leading up to the release of the X. Stood in line and bought one in the store on the 15th. Had nothing but iPhones until now - loving my DroidX!
BUT
As of right now my battery is down to 60% after having been unplugged (when I unplugged I was at 100%) for 1hr 46m 9s!
It shows display at 93% and cell standby at 7%.
I'm running smart battery mode, auto screen brightness, not that many widgets, and I rooted it and have autokiller running on Aggressive.
Do I just have a bad battery? And if so will Verizon (or Moto) give me a new one?
I think I figured out why sometimes my Droid stays on for 1.5 days and sometimes after 6 hour of just being idle the battery is drained.
When wifi is turned on an connected to a network, the cellular signal is way low and it just drains the battery.
I'm writing an android application that collects cell signal strengths.I am having trouble getting the "current" cell signal strength, but I don't have any problem getting the "neighboring" cell signal strengths.To get the current cell signal strength, I created a PhoneStateListener and implemented the onSignalStrengthChanged callback.It works, but not very well.It seems like the signal strength hardly ever changes, and resolution jumps to only a few numbers.I would accept the answer that the resolution of the signal strength hardware is coarse, but when I use the TelephonyManager's getNeighboringCellInfo() method, it works much better.The signal strength readings from neighboring cells change frequently, and they have much better resolution.So, how can I get the current cell signal strength in the same way that I am getting the neighboring cell strengths?It seems odd to me that the functionality of the neighboring cells is better than the current cell.

If anyone knows how, please let me know.

View 5 Replies View RelatedI currently have code that creates rows in a table that hold a string in column 1 with a RadioButton in column 2. There can be a variable number of these rows. That all works just great, but I want to add them to a RadioGroup so only one button can be toggled at a time. When I tried to add the dynamic RadioButton to the RadioGroup AFTER I added it to the table row, I got an error saying that the child (the RadioButton) already had a parent. I agree, it does have one, the TableRow.
can you have radio buttons tied to a radio group inside of a row or, should I just code my own toggle mechanism and avoid RadioGroup all together? I mean, I could code the onClick to unclick all other radio buttons, but I would rather not do this if I can use the build in RadioGroup.
<ScrollView
android:id="@+id/ScrollViewModifyGroups"
android:layout_width="fill_parent"
android:layout_height="fill_parent".............
I have multiple radio buttons which I want to layout using a table but also include them in a single radio group. I have the following xml layout:
<RadioGroup android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:id="@+id/Group1">
<TableLayout android:id="@+id/RadioButtons"
android:layout_width="wrap_content".........
But unfortunately the radio buttons inside the table seem to ignore the fact that they're inside of the RadioGroup tags and because of this you can select more than one radio button at the time. I noticed that by removing the table and just having the radio buttons it works just fine. How can I overcome this? Would it be as simple as declaring the radio group inside of the table instead of outside?
I turned on my Droid this morning to listen to MSNBC and I heard the last 5 minutes of Keith Obermann (5:55 am est) and then all of my news and talk channels disappeared! Channels like CNN, C-SPAN, MSNBC and NPR are all gone from my favorites and the channel line-up. There is nothing in the "News and Public Radio" category.
Has anyone else noticed this? I'm thinking this must be a temporary glitch but I would hate to lose all of these channels. If you have the Sirius/ XM radio app, would you please check this on your Droid?
I currently have code that creates rows in a table that hold a string in column 1 with a RadioButton in column 2. There can be a variable number of these rows so I cannot just create it in the layout xml as radio1, radio2, etc. My code displays the table with the string and RadioButton pairs just great, but I want to add them to a RadioGroup so only one button can be toggled at a time.
