Hello all .
I have a standard non rooted S3 on I9300XXEMG4 in the UK.
Everything on the phone is standard .
I have now started using the ZeroLemon 7000mh extended battery.
Now since the last over the air update to the above rom I noticed the signal strength wasn't as good ... then I started using the extended battery and now my signal drops out every now and then .
I have even noticed a difference in the wifi strength received since using the big battery .
Is this solely because the bigger battery covers the antenna's in the phone or am I imagining things ????
I have checked mobile masts and works in my area and all are fine but im definatly experiencing worse signal strength since using the big battery ... is this the norm or known about or experienced by anyone else so I know its not just me or my phone.
My signal in the area isn't the best and never has been .... I can only get "G" as the best data but now its worse .....
Use original battery and test .

Hello everyone!
I received my Vibrant from the US a week ago and noticed that when 3G is on, the reception is 1/2 bars at most. While it's connected, the device gets hot in the top part and the battery drains like a F1 racing car.
I though I could see how good is the signal and it's about (-90) - (-100) dbm.
I never had reception issues with my previous phone that is 3 years old (HTC Touch Cruise) whose reception is quite good. My company's antenna is about 1 Km far and it's emitting 3G in the WCDMA 2100 MHz band.
Could any setting improve the reception to avoid heating and battery consumption?
Thanks a lot!!
You may want to try to set it to 2G only if you want a good battery life.

Maybe somebody knows an application that switches from 3G to 2G when the reception is not good. It might be very handy.
Also, I wanted to know what levels are acceptable in dbm for a 3G connection that doesn't drain the battery like crazy.
Thanks for your reply!
Generally speaking I'm in good coverage but I'm having this weird issue. Some days after charging over night I unplug the phone and have great battery life that day. Looking at the battery status everything looks as you would expect, cell standby appearing pretty low in the list and showing maybe 1 or 2% 'time without signal'
Then other days, for no apparent reason, my battery life will be terrible and cell standby will be the highest battery drain on the list (40% or so) and showing 100% 'time without signal'. However, and this is the bit I don't understand... I do actually have good signal in both cases. I've tested by sending and receiving texts and calls.
I guess my question is, does anybody know why my phone might 'think' it has no signal even though it does, and why it consumes more battery when this happens?
Something I've noticed also is that 'settings>status>signal strength shows that i do have a signal in both cases (pretty much same values in both too). But, when doing '*#*#4636#*#*' it shows '-0dbm 0 asu' if my phones having the 100% thing.
Same issue here, I have 100% time without signal however I have full 3-4 bars of signal. Charged before nifht, unplugged and lost 25% of battery over night because of this, as if the phone had no coverage at all.
Usually setting it to offline mode and back to online helped, but today it does not help...
Same issue here. Even if the sim card's not in. Too many issues with this phone. Will end up on ebay!
Omg, don't panic dude. Just wait patiently on firmware update

I've got the same issue, well atleast mine says "time without signal 100%" eventho I do have signal most of the time..however my drain seems to small in comparison to yours..it usually takes like 10% - 15% of battery in a full charge, so quite normal.
wonder why it shows 100% time without signal tho....
i have the same problems on my phone. i got the '-0dbm 0 asu' reading working once and the time without connection went down from 100% to 99%. but i was so happy i can't remember what i did :S i tried all different kinds of firmwares. but i'm tryin to get it to work again. :S it had something to do with the cdma or gsm mode on my phone.
let's hope we get it fixed it really drains my battery
In the same boat as you lot. Cell standby battery use is very low but getting reports of "Time without a signal" 99%, even though I have full 4 bars most of the time and make and receive calls with no issue.
Running XWKE7 for what it's worth, are any of you guys on different firmware?
i knew something was odd, i spent today wondering why over 2 hrs my battery dropped from 80% to 50% and even when I try to reboot and recharge, the 'cell standby stats' say its been on since recharge and at 100%.
i'm on XXKG1 with litening rom v 2.2 flashed earlier.

I have a galaxy S3 but the signal strength is awful compared to other phones I have tried side by side. Its fine if there is a strong signal, but cannot cope if the signal drops a bit, so poor reception and dropped calls. Its not hardware as I've had replacements. I've compared to HTC desire and One X. One X had 14-16 asu where this had dropped to about 3-4. At home it hovers around 0-2 asu so it is no good for me.
This isn't just me - a google of galaxy S3 signal problem brings up a few results.
So .. is there anyone on here who knows how the radio ROM is designed on these phones. Does the reciever work low power at the moment and can it be increased in a new ROM, or is this likely to be an inherrent design issue? I want to keep this phone but my 7 days are nearly up and I can't be stuck with a phone that doesn't work as a phone for 24 months.
Both network (vodafone) and Samsung are burying their head in the sand.
Thanks
Just realized that that thing I had to climb up to get to my front door is actually a Verizon Cell phone tower!
So, just noticed this condition today and thought I'd share. I have a Smart Action set up to enable my Home Wi-Fi based on location - Trigger is my location; Actions are to turn on Wi-Fi, turn off Data and Max Ringer.
While home this afternoon I just happened to look at my phone and noticed that my battery seemed to be dropping a little quicker than normal and my cell signal strength was max bars which NEVER NEVER happens at home - kind of on the fringe in my house and I'm lucky to get 3 on a good day. I checked network strength and my 4G was 2147483647 db. Gotta be a world record, right? oh wait . . . is more db bad?
Just got me wondering if, while on the fringe, the radio actively looks for a signal (like it does between 1X, 3G and 4G) and maybe gets stuck in some type of high output state. Would explain some of the intermittent hi-temp, unusual battery drain I experience occaisionally/intermittently. Just so we're clear - I'm not complaining at all about my Maxx battery.
Running stock .211 rooted.

I thought after 120 db it actually means you've lost signal.....optimal is between 80 to 120....
I could be wrong
I saw that exact same thing on my Maxx the other day. I also noticed battery declining due to it. Not sure what it means though.

It means your have no signal, and your battery is dying from your LTE radio trying to find signal. dbm between -80 and -120 is not optimal, that is the range where verizon techs will tell you that you may experience data connectivity issues. The lower the dbm the better signal you have, however most extended 4g service areas are at this quality. I have seen some locations, closer to the towers, where I have gotten signal around -60dbm, which gave about 38mbps down and around 16mbps up.
I ordered a sleek 4g signal booster from wilson electronics, which will get here tomorrow, and will let you guys know how much improvement I get in areas with different signal strengths.
i've seen it countless times on my razr. I think it's just a bug
No signal but my signal bars show as full? That makes no sense whatsoever. I think I have to agree that it is just a weird bug.

I'll tell the truth. Wilson electronics sleek 4g-v is not going to improve SINR signal strength (that's what you need for better LTE speed), however it will improve RSSI signal, but this is not going to help for LTE. If you want a good LTE amplifier, you are looking to spend about $500 that includes outdoor, indoor antenna and SINR amplifier. SINR is more important then RSSI or DBM for LTE
Hi all!
When I'm at home, I get about 3 bars of 3G signal. I have had this phone for about 3 days and the battery life is really bad, using basic apps drains my battery really fast. Should I change the network to 2G? Does the poor 3G signal affect the battery life significantly?
Much appreciated!
If 2G is enough for you, change it. It uses less battery even with good 3G signal...
And yes, a poor signal always uses much more battery life than good signal, no matter GSM/2G/3G/4G...
Yes, I have noticed that in areas where signal is poor (1-2 bars), battery drains significantly faster. It's quite irritating since this issue is non-existent on iPhones. I wonder if a software update can fix this.

It's the technique of every phone, even on iPhones... the amount sure can vary, but it's not inexistent...
I have about 1-2 bars at home and over night it takes about 2-3% of charge, very similar like iPhone I had before...
it does on mine. at work i get full signal and though i use it a fair bit, it doesnt seem to use too much battery but at home where i get terrible battery life it seems to use more battery
