Anyone have any ideas as to why all of a sudden I have lost 75% signal strength? Everyone else is still at full strength outdoors, while I'm struggling with 2 bars. Indoors 2 bars for them will result in 1/2 bar for me...any ideas?
I upgraded the radio (as I was using my signature radio) loaded 1.14.25.35 and same results...

Does anyone else seem to have terrible wireless signal? Using Wireless N, the highest reported link speed (from android wireless settings) I have seen is 58mbps. But, averages around 35-40. Seen as low as 1 being only 20ft from the router. Wifi Analyzer reports signal strength at -83dbm from about 15 feet away. The signal seems so terrible that I normally switch to 4G just to browse the internet.
My old incredible was always pegged at 65+.
What gives?
Yeah, I don't know what's up the WiFi in the Charge. I had a Sammy Vibrant before and it always had 3 full bars of WiFi in my house, while my charge is only showing one or less. I wonder if they put that low-power WiFi in our phones, the same one that was put in the Nexus S 4G. They've had a lot of signal issues with those also.

I have a huge battery drain, and i think that is because i have low signal (look at the picture).
I tried to recalibrate battery for two times, and use it for 2-3 days, but it's alway the same.
I get maybe 7h with normal use. 50% of the time with 3G/EDGE, 50% with WIFI. screen time 1h, and turned off Auto sync.
Can someone help me? I need my phone whole day, not 7h. :S
EDIT: I'm using stock 4.0.4 with matr1x kernel
Bump?
Can't really help you as cell reception is based on the quality of the carrier. I normally experience -95 dBm and I believe it is a cause for such high drain too.
The only thing I could recommend is try flashing a different radio and see if you get a better signal?

BetterBatteryStats can let you know if it's not the radio. To test if it is the radio, try switching to 2G only.
Well, it was 3G-s fault. I switched to 2G and now there is no battery drain.
BUT, i still don't know why is there no 3G network in my house.
I have SGSII on my shelf, with the same carrier and it has 3G.
There is 3G at your house. It is just weak, much like me. A few too many concrete walls where i'm at.
Cell signals are done through waves which have to penetrate through walls and other solid objects, this vastly weakens the signal. Once you hit the ~-100dB mark your phone will start throwing more power into it's antenna to compensate, much further and it ditches 3G and goes to 2G assuming it has better coverage. Around the 100dB mark it tends to stay with 3G if data is on though which can start chewing through battery. It would be able to play around with the parameters but i don't see this happening anytime soon.
Compare the dB reading on your SGS2 and Nexus S. If it's much worse on the Nexus S, try flashing a different radio.
I have the same problem, i just switch back to 2g when i get back home and at night. for some reason, 2g networks tend to always have stronger reception
Anyone else noticed this? In areas of med to low LTE signal (-109 dBm), there are times when something locks up inside the radio and Signal Strength under Status will never change again no matter where I move the phone. During this funky mode, the battery is dropping rapidly during idle... Maybe 10% per hour. Something is wrong. During this same time android battery history shows yellow medium signal and voice calls work fine. There is also no runaway process cpu ussage or awake time. The only thing wrong and drawing too much juice is radio. If I toggle airplane mode or toggle wifi off/on the problem is solved for a while. I have VRALF2 firmware.
same problems here

I have the same problem. Have went through many sim cards and factory resets. After 5 phone I finally have one that holds the signal a little better and does not go into this "funky mode". With the previous 4 (white 32gig) verizon phone I would burn through a battery in 6 hours at work. It would start with a drop in signal strengh at around -93 or so. Nothing would fix it. I finally got a blue 32gig and it seems to hold the signal to around -99. I don't know if I got a better batch of phones. But it seems to help me get through a day at work.

That's not normal. Where I work I get 3g primarily but also 4g in the front of the building.....in the far back I get 1x. I have had my phone totally drop data for a while (like the radio sleeps or something) but never had the radio stick between 4g and 3g. I also live right on the edge of a 4g/3g line and my dbm right now is 111 on 4g LTE......If this was normal I would have had the situation your having since my signal is basically identical to yours. I would return it or at the very least contact Samsung. I'm sure Samsung will tell you to send it in for repair.
I have very weak signal at my house also. S3 switches from LTE to 3G and 1X and sometimes loosing signal completely downstairs but upstairs usually I get solid LTE with around -99dBm and ~10Mbps transfers. During this network jumping my battery drains very fast also but I never had my radio constantly locked at one frequency or signal strength. And I can directly compare signal reception to my wife's Fascinate and S3 loses this competition badly. Fascinate never completely lost signal at our house and it rarely jumps to 1X.
I did a factory reset yesterday and so far so good... I''ll update as time goes on.
As far as signal strength goes in general,my wife's Droid Charge always pulls in a few more LTE dBm's than my GS3. Based on general public feedback, GS3 is below average on signal and radio issues. It's too bad because the rest of the phone is above average.
It's been 2 days after the factory reset and no problems with battery drain or radio lock up.
The only app that I could maybe try and blame is Elixir 2's create widget feature for signal strength. This always returned bogus values and may have embedded itself at an unholy level. Simply uninstalling elixir 2 didn't fix it.
If anyone still cares... I found my radio lockup and battery drain issues returned only after I reinstalled Better Battery Stats. I again removed it and will see if I stay good.
I flashed CM 10.2 (the stable build) a few days ago and I've noticed that the cell signal has been much worse than before when I was on stock. Im getting 1 bar in areas where I used to get to get 3 or more. I've read in other threads that google changed the bar measurement with 4.3, but I'm also experiencing severe battery drain with 20% of my cell idle time being "no signal". I didn't have this problem before 10.2. Has anyone else experienced this and/or found a solution?
I just got a P7 pro and ran a speed test. I was consistently getting over 300mbps indoor, yet my signal strength was maybe one bar or two. Every once in a while the icon will fill up with white completely but always stays around one bar. Is this kind of behavior normal?
