Android :: 100% Time Without Signal Ruining Battery
Jul 7, 2010
I have had the LG Ally for about a week and was expecting my battery to not last more than a day. When it wouldn't last for more than a few hours with light use I figured there must be something wrong. I have an app killer and make sure only the programs I need are running. The standby time is the problem. It is always taking up at least 65% followed by display which takes up less than 30%. When clicking on standby time, the time without signal is ALWAYS 100%. Doing research I haven't heard of anyone having 100% all the time. Things I have tried so far are airplane mode, turning the phone on/off, and dialing *#*#4636#*#* to change the radio thing multiple times. Nothing will take it below 100%. Strange thing is that I can still receive calls, texts, and use the internet. It seems unlikely that after only a week of owning the phone that I would already have to do a reset. Could there be a new bug different from the 50% TWS bug?Please let me know if anyone has had this problem and/or knows how to fix it.

My droid x signal pretty much always between -92dBm and -87dBm with 1-3 3g bars. My former droid eris would get -92dBm with 1 bar and also drain incredibly fast.
On the droid x, if I go into google maps, the circle of the cell tower appears and the place I live at is half way within the edge of the circle and the other half is outside of the circle. I always seem to be connected to this tower. Bad luck I guess that I'm on the outskirts of the circle.
Does anyone know how cell towers are distributed? Do they overlap sometimes?
I run pandora with the screen off for a half hour with the screen off and my battery is down to 70%. I have about 15% screen brightness and battery saving mode on.
yesterday, I was on meebo for an hour and 45 minutes and it was down to 60% from a full charge.

I've had a Desire for two weeks now. I was in love with the phone... until this problem came up.
I use Outlook and Microsoft Exchange -- and had read all about how Android synced easily. And it did at first. Then, 10 days ago, the calendar stopped syncing. I got a "Client/Server conversion error," and no sync. The problem only effected my calendar -- mail and contacts were synced just fine. After reading a few forums, I did a "Remove account," re-installed the account. It worked fine again. No big deal.
Then it happened again today. I did the Remove/re-install thing again, and again it was cured. Until six hours later.
Is anyone else having this problem with their calendar/exchange sync? Any solution guesses?
Without being able to sync my phone to Outlook, the Desire I love so much is somewhere between frustrating and infuriating.

Has anyone run into this, like with the other Android phones out there? Does toggling the airplane really fix this?

What exactly are these things and what do they mean? I tried searching and reading threads I see them but no explanation on what they are. Can you guys hekp me out here. I was having battery trouble after froyo update so I did the hard reset and the cdma only trick to see if this helps.

So I installed froyo like everyone else and started to experience bad battery life. Just like everyone else I did a hard reset and did away with task killers, etc.... I checked to make sure Facebook update was uninstalled and then did the auto CDMA prl check. Problem is that I am still experiencing bad battery life....6-7 hrs max on light usage. I noticed that my "time without signal" was ticking up even though I have clear signal and so forth.

All this talk about 3G/4G speeds, hotspot, etc.... I was thinking just how much time everyone spends away from a WiFi connection they can use? My normal day consists of getting up, going to work, and coming home. I spend maybe 2-2.5 hours away from the house while driving to/from work, picking/dropping off kids, going to the grocery store, etc.So usually when I want to access something on my phone, I will be around a WiFi signal I can use (Home or Office).I would think with WiFi on the EVO, thats where most of my data usage is going to be.
When using android apps, they use WiFi (if available) correct?

I seem to have a poor signal alot of the time. 1 or 2 bars is not unusual in places my old phone used to have full signal strength. It went on roaming for some reason in the shopping centre today. It is always on H or nothing. My old phone used to drop onto edge and GPRS if it didn't get a H signal. And what about 3G? An all singing all dancing phone is no good if it cant perform its main function.

I cant figure out why my girlfriends x has the wifi and the 3g signal on the status bar at the same time. When my wifi is on, my 3g Indicator disappears. What is supposed to happen?

I've noticed within the past month or two my Eris has been having a hard time searching for a gps signal. I'm on the Leak v.3. Sometimes it takes a matter of a min to lock on other times much longer, and this past weekend I had an indecent where it never found the signal for about a 1/2hr or more.

My thunderbolt is acting up. It keeps losing signal and takes a long time to boot up. Will Verizon allow me to upgrade early even though I'm not due til November? ADR6400L

I want to reach out to others here before I take my Moment back to Best Buy to exchange it for another Moment.
My signal strength fluctuates wildly just sitting in the same spot. With the Hero I got a constant 5 of 6 bars, but the Moment will vary between 0 and 5 of 6 bars. But it's more complicated than that.
It seems that whenever the EVDO data kicks in, it causes the signal strength to drop to 0 or 1 bar. Once the data is idle, the EVDO indicator turns grey and then changes from EV(^v) to EV(D). At that point the single strength will return to 3 or 4 bars.
At times, though not as consistently or often, the EVDO connection will fall back to 1xRTT and will switch between them every few minutes. This will occur even when the signal strength bars are in the 3 to 4 range.
So, the my questions are...
Does the signal strength apply to the data signal or just the voice signal?
Is there any legitimate reason for the signal strength to vary wildly like I've described, even when sitting in the same recliner where the Hero had a constant 5 bar connection and data service that never wavered?
Is anyone else having signal strength and/or data service issues?
Should I exchange the Moment for another Moment or will I likely experience the same issue?

So I'd been wondering why my battery at work doesn't last that long. I knew signal strength was an issue, but then I opened up Spare Parts and checked battery usage. Normally ebuddy is only running when it does quick message checks and has a pretty short partial wake time. Out here where it keeps having to reconnect, the phone has a 100% running time, and ebuddy is always on! Fair warning to all my instant message addicts.

First I want to acheive battery status and signal strength instantly. For Battery Status, we can use SystemProperties.get ("status.battery.level_raw") to get current battery level. This class is not in SDK reference, but we can see this function is used in BatteryService and other fields. I use it successfully But for Signal Strength, I only find the way to use onSignalStrengthChange(int asu) which only gives us an "asu", new version seems to support onSignalStrengthsChange(....). But now, is there better ways for exact signal strength?

I'm wondering if this is a common verizon thing or a phone thing.Every time the verizon signal is lost or detected my music pauses for a split second. this becomes very annoying while commuting to and from work everyday underground where the signal is lost and gained about 17 times due to the depth of the subway. how can i fix this? this is not an email sync issue but a carrier signal detection issue.

I had a motorola droid that I recently sold on ebay in order to purchase the Incredible and I was just wondering did anyone else here go from a droid to a incred. Is everything pretty similar other then the speed/camera of course? I know the complaints against the droid were battery life and signal which are the same Im hearing for the htc model but I figured out a way around those.

I just downloaded a free program called "TimeSignal." All the program does is run in the background and cause your phone to briefly vibrate on the hour, perfect for when I am in a loud place and have the phone in my pocket. It's great for when you get involved in something (like right now when I am playing on the computer) and completely lose track of time. You set set the program's hours of operation and it has a few other settings that I haven't played with. The program seems to have no problems running on my Droid.

I'm sure many of the "poor battery life" reports were pre-mature, as people didn't realize their new rechargable has to condition itself, but today I ran into a new situation. This is my second Droid, since replacing original, due to wanting to confirm a faulty antenna, and trying to solve the 3G->1x issue.
Reception at my house is a crap shoot, where moving my phone 6 inches on my desk make speed tests go from 1.5Mb to 300k. So today I'm at mom's, 2 miles away, and we are both equidistant from the VZ store, which is also 2 miles away. However at her house, I pretty much get (0) bars. I left my house with about a 95% charge, pulling it from the plug before I left. I used it maybe 15min to try to resolve her router issue. After 6 days, my battery was good for a at least 18-24hrs of light browsing and mail checking. Well today, It was down to 50% after 3 hours, while flipping back and forth from 3G ->1x. I had (0) bars most of the time and noticed that the battery was warmer than usual. Signal strength was between -95dBM and -110dBm. Now "almost" 5 hours after pulling from the plug, I'm down to 20%. If my hypothesis is correct, I bet the charge will last the night now that the channels have stabilized.

As of the last 2 weeks or so I would say, a few problems have come up with my D1.
The first is the GPS never can locate my phone anymore when im in maps. It just continues to say trying to locate, and does nothing else. It used to locate just fine, and basically has just stopped.
Second is I loose all of my signal bars and then have no service according to my phone.
Third is my battery life has just turned to complete crap. I had it fully charged this morning before I left at 10:30, and it was dead by 4. Did a few occasional texts, nothing else and it was done.
All of these things literally came out of no where, didn't change kernels or anything else that I can think of. I am running CM6 with one of P3's kernels.

So I know it's usually best to place your phone in airplane mode when your phone doesn't have signal; however, are there any alternatives to this if you're in an area that constantly gives no reception? I live in the first floor apartment and I'm guessing the materials of the building completely kill my cell signal because I barely ever have more than one bar of signal if any signal at all. For example, my cell standby is usually about 50-55% time without signal during a given day.
I'm wondering if there is another setting or perhaps an app that will save some battery.

how to change the icon of its battery, WiFi and signal bar. I was able to successfully root the phone..I wanted the phone to look original by changing those icons. Even if i try to apply different themes those icons wont change. And another problem is Phone Coverage Signal weak or lost, another phone can receive 50% or full coverage signal.

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.

Edit: Well, it looks like I found what the problem was. Apparently the time without signal being stuck at 50% is a known android bug that a lot of phones have. Tried the fix posted at the bottom of this thread FWIW: New LG Ally has 50% Time Without Signal Bug
and it seems to be working for me, phones been on for 10 minutes and my time without signal is reporting at 0%
Original Post. Am I just not understanding what it means? I looked at the cell standby information about an hour ago, and I panicked when I saw that it said the phone had been on for 1d 5 hours since I turned it on, and the time without signal was 50%.
I rebooted the phone to get a fresh reading tomorrow before running back to the at&t store to get my money back, and after the phone had been on for a few minutes I went to check the info again, and saw that the phone had been on for 8 minutes, and the time without signal was 50%. Now service isn't amazing in my house but I generally get 3 bars at my desk, with it fluctuating between 2-4. If I pick it up and hold it, it'll drop to 1-2, sometimes losing signal completely very briefly (thank you antenna design). But, the phone had been sitting on my desk untouched, so it seemed really strange to me that it would have been without service 4 minutes out of the 8 it had been on.
Went into my display settings and set the display to stay on for 30 minutes, and have been sitting in the phone status screen now watching the bars (going between 3-4 now for the time I've been watching it) and the signal strength (going between -97 dBm 8 asu to -81 dBm 16 asu). I haven't been sitting here staring at it, but I've been glancing at it often enough that I feel confident in saying that the phone has not lost signal in the last hour. However I can go into the cell standby details screen right now, and it's reporting the Time on as 1 hour 9 minutes, and time without signal.....50%. Am I missing something, is it trying to say that it's been without signal for 30 minutes of the last hour, or am I misunderstanding what "time without signal" means (though it seems pretty straightforward).
Anyone else noticing this on their phone?

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 was looking through the market this morning and found an app I had not seen before "Signal Status". It allows you to show the signal status in dBm on the status bar. Has anyone tried it. It seems to work great but I wonder about battery drain?

I'm writing because I've recently removed the HtcLockScreen.apk file from my phone to get the vanilla Android lock screen, which I like a lot better than HTC's. However, someone mentioned that it could affect my battery life and to keep an eye out on my up time and awake time. Well, before and after a restart, the up time and awake time are exactly the same. Does this mean the phone isn't sleeping? If so, how can I fix this? I'm running a rooted EVO with 2.2 and no custom ROM's.

A little history: Had the phone since launch. Did most of the battery "tricks" when they came out: GSM fix, stop GTalk auto login, tried the on-off-on charge thing, but never ever got more than a minute of red LED before it turned green again, turned auto-sync off, etc. I usually have what I consider pretty good battery life. I've almost never run out of power during the day, and the few times I did it was because of pretty heavy (for me) usage. When I try to see how long I can go without charging I've usually gotten through 28-30 hours before I had to plug in. (please spare me the "your battery suxxx! I've gone 7 months since my last charge and I'm at 98%" posts)
So last night I charged to full battery, unplugged cause I had to charge my BT headphones too, then went to bed. 7+ hours later I wake up and my battery is around 10%. Usually when I unplug I lose less than 10% through the night.
So here is the obvious culprit: I've recently gotten stable 4G in my home and I forgot to turn it off when I went to bed. Easy game.
But....................
I went to look at a few settings to confirm that it wasn't something else and I see something really odd.
Up Time was 120 hours
Awake Time was 117 hours?
Now, if I am understanding this properly, this means my phone was booted up 5 days ago and of those 5 days my phone was only asleep for 3 hours? Is this possible? (I am no techie so I very well could be misunderstanding it)
I have not been having battery problems for all 5 days, only last night, but these numbers seem to indicate I should barely have been able to get through half a day without the battery dying for this entire period. I looked at my "running services" and there were a ton of things that had been running for the entire 120 hours. I have checked this in the past when reading battery threads, but since I have been satisfied with my battery life in general, it's not something I really check regularly, so I have no clue if this is a recent development or not.
The battery usage showed around 42-43% for both Phone Idle and Cell Standby since I unplugged last night.
I also noticed that I had turned off auto-syncing, but still had background data "always on". But again, this is something that would have been the case for the entire last 5 days (and more, really), so it should not be the cause of last night's drop.

How much time it takes for your battery to drop 10% when you're on 4G doing no downloads, no streaming, no Youtubing, nothing? In my case just 30 min. Complete discharge in approx 4 hours The temperature is very hot too. Do not put it under the pillow.check it out, this is ultimately just a 30 min test, and post it here (say to voice dialer "Open battery Info" for battery numbers and temperature instead of bars)
