it seems that my friends Galaxy SII gets better Wifi reception in my house than I get with my Galaxy SIII.
Because he has more bars??? Better throughput?? What is your basis for this assumption?
I had more bars of WiFi in my house with my iPhone 4 than I do with my Galaxy S3, but aside from some visual representation of connectivity, there doesn't appear to be any difference in speed or connection.
I'm basing it on the number of bars it shows lit up on the Wifi Icon, I assumed since it was the same manufacturer it would be okay to compare them that way.
Is it an unfair comparison?
I have both the S2 and the S3 witch I bought 5 days ago.
I am watching Sopcast TV in my patio.
My router is Netgear 900, with both G. and N Wifi and a
signal booster build in.
My S2 has all the bars full on N, while the S3 is 'out of range'.
I have to use the S3 on the G. to have the same stream.
So yes, the S2 has better antenna!

There are a couple posts around here about WiFI disconnects on the SIII. I am experiencing them myself. Not overly frequent, but often enough to disrupt some of my Tasker proviels, and very annoyting.
As long as I don't have a disconnect, I find it performs very well.

I would agree with you that except for the wifi (and some picky things with the BT), but I find the phone disconnects about once every two minutes on average and that means that half the time I'm pressing the send key and the app tells me there's not connection..... And I get great download speeds on Speedtest that are my full bandwidth (58/8), so it's not like my Market updates are failing.
Thanks for the tip on hoe to get into service mode stan.s and I just tried it with the wifi powersave off, there did'nt seem to be any initial boost in reception.
The download speed is significantly lower for me compared to the evo lte.

You're correct! If you re-read my post (I edited it) you'll find that that simply turning off the regular power saving off gives you the 'best' (used loosely) signal. The hidden switch with the regular power savings is only slightly better than power saving alone.
Also, that HP Touchpad is on another floor, two walls away and the GSIII was two feet from the router....
Thanks Stan, wasn't having any issues but it's only gotta be better, right?...

without hope, there's not much to look forward to.... I have two hopes right now,
1. a fix for the firmware counter and
2. a fix for the wifi (though someone suggested and I talked to Samsung about this) that the issue is a chip incompatibility issue like the old Broadcom/Antheros chip problems which might explain why some people simply don't have an issue or only on some networks have an issue.

I don't have much hope on count 2. I had similar WiFi problems on my Captivate that never got acknowledged by Samsung, or fixed. The good news for that was setting the IP address as static was a successful work-around. In the case of the SGIII, no work-around I know of. The only good news for me is it isn't near as frequent as for you.
Two strike-outs on Samsung and WiFi for me now

I was also experiencing this same issue. I was sitting 2 feet from my router and with the Wifi power save on, it was connected at 802.11b and 11mbps! After turning wifi power save off it connected to 802.11n speeds (like it should have) at 65mbps. I also get better signal at the other end of the house too.

Following many SGS2 battery drain threads, I've come to this conclusion that it is due to the rare combo of SGS2 with certain routers. This might be what the AOS bug is all about.
With newer kernels we are no longer able to see this drain easily on BetterBatteruStats. Instead, I've used SystemTunerPro to do many many recordings at 1 minute intervals to record the CPU usage with wifi on/off, with my regular set up, and with a bare rom with nothing else installed.
My findings: with a freshly installed rom or not, as soon as wifi is connected to my Dlink DIR-655, the CPU usage increases from roughly 0.3% to 1% (averaged over a 10-minute sampling period with screen off, background sync off), which drops back down as soon as wifi is turned off. More interesting, when the Dlink router is out of range, turning on wifi does NOT drain the battery.
I was puzzled by the result, so I went to a local coffee shop and connect to the public wifi access point, no increase with CPU usage whether on wifi or 3g only. So something is wrong with the Dlink DIR-655.
So, following some searches, this seems to be a somewhat recognized issue by some SGS2 owners (not too may because I bet not many would not suspect that the router could be the culprit). I tried changing from auto channel to CH8...11, changing from wireless N to G, changing authentication from wpa to wep to open, each time I change something, I made a new recording with wifi on compared to wifi off. Same thing. Only when connected to my Dlink DIR-655 does the drain occur.
Note: you cannot tell if your battery is being drained by just analyzing your wakelocks. In this wifi battery drain test, no wakelock stands out in terms of time on CPU. But if you use battery monitor widget pro, you can leave your screen off and let it plot. If with screen off your current draw is 100mh or above, here you have a battery drain. Your phone can very well be in "deep sleep" when this happens.
What to do:
I use JuiceDefender to make sure wifi is turned off when screen is off. You should set wifi sleep policy to never. Even though you could set it to turn off when screen is off, sometimes wifi cannot be turned off successfully using this method. When that happens battery drains without you knowing. This is why people have a fully charged phone before going to sleep and wake up with a dead battery.
Now it's your turn to share your experiences. If your SGS2 drains battery:
Do you have a Dlink router?
Do you have a DIR-655?
Or do you have this router by but have no battery drain.

I have the same problem with my DIR 655 and SGS2. In 18 hours with WIFI on, Android OS was top process with around 9h runtime. I also changed the WPA, channel etc. settings without result. Currently I want to downgrade the router firmware from 1.35NA to 1.21. In BBS, if I order the kernel wakelock by count I get one for about 140K, and it's active only when connected to wireless. I think the router doesn't let the SGS2 to sleep for more than several hundred miliseconds. You may play with advanced wireless settings in the router and change the Beacon Period and DTIM Interval values. I only hope that DLink will address this issue.
Cheers
Hi Sysod,
Did changing thevbeacon period solve your issue? Or downgrading router firmware to 1.21. From the Dlink changelog I don't see how it can improve our situation.
Sent from my GT-I9100 using Tapatalk
I have played a bit with beacon settings without succes. I noticed a decrease in battery drain, but also a decrease in wireless performance and I stopped tweaking. I'll see if dlink do something about it or else I'll buy a new router. The firmware to my router can't be downgraded, unfortunately, even with the russian modified one.:banghead:

Why I didn't think of this? After reading that thread, I fired up Wireshark on the laptop. I found many broadcast ARP packets originating from my 2 PCs. The culprit was the Cannon scanner software. After I disabled it, no more broadcasts and no more battery drain. Android OS is still high, but this might be a fault in reading.

This router is terrible. I have had so many issue with it as well as mobile/laptop battery drain.
I just got a new router (not from Dlink) and battery levels consumption is what I would call normal, as in what I would get at work/wifi AP.
I guess this about confirm the combination of dlink dir 655 and sgs2 is bad for battery. I was going bonkers with my battery flat out in few hours once connected to my dir655.
Without connecting to wifi, based battery usage apps, I can get about 1% for 20-23 minutes and it took 1% for 6 minutes with wifi connected.
Now that I found this thread, I will be using my older 150n linksys/Cisco, for the next few hours to check if this is really a dlink issue combo with android since my son battery on his galaxy mini and the older galaxy s also flat out in less than 10 hours.

So, did it help?
DLink DIR-615, same issue, I was about to RMA the phone!
PS:
My fix with an updated DLink DIR-615: change WPA2 Protection from TKIP+AES to AES (TKIP only did not work with my i9100). In G Only it seemed draining even less (quick test), but I got this router for N+G and it seems working now.
Changing the DTIM interval from 1 to 255 solved the issue for me.
Had a battery loss of ~4% in 6-7 hours.
Let me know if this worked for you.

I too am having this issue, but not on every single ROM that I run. I have a SII and so does my wife, running different ROMs. My phone has this battery drain problem with the Blu Kuban Kernal where I did not see it before. My wife is running Calkins old GB Rom and does not seem to have the issue. Changing the DTIM interval from 1 to 255 did not solve the issue for me, although it did seem to help. My phone stayed in deep sleep mode about 5 percent moer after changing this setting.

Hello all,
Recently i bought Razr XT910 (1 month ago). Because of failure on power button on first handset, provider exchanged it with new handset, now everything is ok except..
On both handsets comes up overheating issue when i was using HSDPA/3G network data for internet surfing. In 20-30 minutes back side and front side (LCD) comes very hot. Application for battery temp shows in idle cca 27C after 30 minutes just web browsing comes up to and over 40C.
This never happen if i play games, watch videos. Also heating is not present if i access and browse over internet on WIFI connection. And i didnt root phone yet and i already done factory defaults.
Has anyone experienced the same problem? Any suggestions?
Specific of my phone:
651.73.30.XT910.NonEFIGSRetail.en.EU
Android Version: 2.3.5
SPU: 11 M1-2
Radio Version: U_03.1C.85P
Bootloader Version: 0A.67
Webtop version: WT-2.0.0-113
Thanks
Try to use the phone at different places. Check the signal reception. Low reception means higher transmitting power needed. So, more power needed and makes the battery and transmitter circuit work harder.

Thanks for reply. I tried this at work where i have full signal HSDPA (antena is 100 meters away and signal is very good), and at home i have very good signal on 3G network. I am not sure that the signal strenght is reason for heating... What about Radio Version: U_03.1C.91P, what improvements does it have?
I am on Asia GSM , HSDPA with 85P baseband. Everyday I download several podcasts from twit.tv and it is getting warm, but it cools back to normal after the download is finished.

Normally you see high temps with heavy 4G LTE/CDMA phones. Haven't heard of many GSM phones on any brand ever overheating. May want to return it again. Sounds faulty to me, and the hotter you run, the worse your battery life will be.
@got556
I read about phones 4G LTE/CDMA with high temps, but as far as i know my phone is 3G (gsmarena). Mybe it is faulty, but this is second one with same issue.
@bahathir
can you mesure and post here battery temp while dowloanding or surfing internet for 30 minutes? Mine also cool down when surfing is finished, but meanwhile...it worries me.
I will check background services for activity.
Started at CPU temp : 31.5 degree Celsius. I am using OS Monitor app.
Opened YouTube and watched one of the clips in TheAlexJonesChannel. At the end of 7 minutes clip, CPU temperature was 35 degrees Celsius.
Next 15 minutes clip, temperature was 37 degree Celsius.
Another 15 minutes clip, the temperature was 38 degree Celsius.
Signal strength : -89 dBm. WCDMA only mode
Room temperature : 26 degree Celsius.
Now, it cools as nothing was happened.

I wouldn't call it was overheating since your case is normal. If you surf 30minutes nonstop over wcdma, any phone will get noticebly hotter but it wouldn't like you can't touch it.

What he said. An active mobile data connection will produce a lot of heat, especially when using 3G. When on 4G, your phone is using up a much smaller portion of the total available bandwidth so the radio doesn't have to work as hard, whereas over 3G your device and radio have to work much harder to maintain the necessary data rate.
This can be compounded by factors like ambient temperature, GPU accelerated applications (browser), the physical layout of the device's hardware, and even how you hold your phone while using it.
The good news is, 40°C is not a 'dangerous' temperature level for your battery. Given how high your ambient/idle temperatures are, you're really not generating that much more heat.
In general, I don't think you have to start worrying about Li-Ion batteries until they hit about 45-50°C (don't quote me on that), at which point you start running into issues like thermal runaway and damage to the battery.
Hope that helps.

Sorry, double post, but this is important:
Every Android device I've worked with will generate MUCH more heat when connected to AC power (there is a scientific term for this phenomenon, but the name escapes me). With rooted devices, I tend to account for this by creating an underclocked profile in SetCPU for when the device is plugged in.

Hi all.. My Razr XT910 touches 45° when I play games like angry birds or similar ones..is it considered normal?
Sent from my XT910 using XDA
Hi guys,
I am sorry for (very) late reply Recently i hit 44°C with active web browsing (facebook,news pages...) and i didnt watch any movies in about 20 minutes. The phone was really hot and it was very uncomfortable to hold it and touch it. In the meantime i contacted motorola support. After their advise i set phone to factory defaults and then i also exchange micro sim card (for free) just in caseif there is any problem with it. But problem is still present. So i decided to take phone to repair centre. They tested the phone for a few days and they said the phone is working normally. They also reflashed my current SW....On friday i got phone back and problem is still here...Now I wonder how they tested the phone and what is for them to normal operation. And i am also stuck at SW version. Does anyone know what are differences betwen GB,FR,DE, NonEFIGS and other versions? Is there just language difference or is also hardware diferences?
I am also worried what will happen in summer with high temperatures outside..
Well, I don't think is something unusual... Its same like your laptop - if the system is busy and the processor has lot of work, it gets simply hot..
Keep in mind that the razr has two cores and if you are playing games or watching movies or even browsing web containing some flash etc. it may get hot because the cores are running at 1,2ghz and it generates heat...
I don't think its something surprising and you will face it with every nowadays smartphone..
If the temperature don't get down after few minutes the phone is idle, check if there is some stuck process because it seems that most likely there is something running on background...
I personally use the System Tuner which gives me a great overview about the current phone's load etc...
@maarawoe
i undarstand what you are trying to say. But web browsing over WIFI does not generate that much heat, the phone gets a little warm not hot as on mobile data (aprox. 35-36°C) and also when playing angry birds or something dos not get that hot.
As i said i am just concerned what will happen on summer time.I hope that the phone will not explode
I will try that app to see more details what is happening with system.

WiFi hotspots are usually 100m away at most; but since the range from cell towers can be measured in kilometres/miles, the power needed to talk to them is much higher. Some of this power is lost as heat. All devices with HSPA and LTE radios get somewhat hotter when the data connection is used heavily.
Recently trouble shot this same problem for someone else. Try this:
1) Turn off Wi-Fi
2) Go into wireless settings and DELETE the saved profile for the Wi-Fi network you're using (make sure you know the network key first)
3) Turn on Wi-Fi, reconnect to the network.
High temperatures are common under certain conditions, such as being connected to AC power, using multiple radios simultaneously (ex: GPS + 4G), CPU/GPU intensive applications, and of course high ambient temperature.
45°C is not dangerously high, but can indicate other problems. Anything higher than 50°C and you may start experience issues like thermal runaway (battery rapidly discharges).

Hi, thanks for replies.
@JPtheSmith - high temperatures are present only browsing net over 3G (we dont have 4G..yet). Even if Wifi is turned off. If i use Wifi for web i dont get so high temperatures. And the ambient where i use my phone is around 20-25°C. Maybe there is some incompatibility between phone gsm module and provider network. I will try to get another provider sim and check it.
I had a long talk with Verizon tech support about high temperatures.
The main causes.
1. Bad signal area, makes the phone work harder.
2. Running to many apps. To many Background apps can and will over-tax your phone.
3. Last but not least, HD games will max out your phones resources.

Cell standby drain cannot be confirmed by all people and is related to the 3G setup, antennas and location of your provider.
Here the network show a very bad case of hopping when switching to/from IDLE (fast dormancy) which drains the battery in no time.
I'm currently running Juicedefender Ultimate beta with AOSP helper which switches to 2G when the screen is off and no data is transferred. Only issue is that you'll loose connectivity twice (3G->2G and 2G->3G) for a very short time but other than that it seems to work fine and has solved my battery drain problem.
I've been used to switch back to 2G as soon as I don't need 3G/HSPA with my S1 as it's drain is even worse, so it's no big change for me

i conquer on this.
i do use now 2x battery saver, which does the same thing as the juicedefender, but even before that, my battery is very well managed. I would assume that the fact of cell standby being on the top of the list when you havent been using the phone for anything else is logical to be there. That IS what will be draining the battery. I would only see the problem on those handsets that this drain is not within acceptable limits, ie, whatever people have measured as normal drain for these circomstances.
I use juicedefender and with the latest update the battery drain is less than 2% an hour, im happy with that
Ive always found by the the biggest drain in standby being data always being on
That's not totally correct. Data is not what is actually draining your battery (at least it never was for me).
It's 3G not being in IDLE due to sending/receiving data, fast dormancy not being (properly) supported by the network or the network provider having a badly configured/balanced network.
If you switch to 2G, you'll find that your phone can run 2 days with data enabled if not heavily used.
Big exception seems to be Exchange's ActiveSync which is, when an account is configured (whether enabled or not) always top-of-the-list in BetterBatteryStats. But well... Exchange sucks anyway =)
I should have typed 3g data, this single act of letting the 3g connection be managed by juicedefender doubled my battery life
Yeh i have no idea for the technical reason but managing the 3g connection makes a big difference to me
hmm i am not aware of the actual network causing problems with the drain issue during 3g/2g signal. I only knew that when the signal is bad in general or you get no signal at all, then the phone is wasting too much energy trying to log on to a network itself.
i have the 3g swap on my 2x battery saver to rotate every 5min when the screen is off. Its the smallest amount of time you can apply. However i dont know if im the average phone user, as i see here lots of people doing a lot more things with their handsets during a day.
Not so sure about the 3G data thing but I'm only using the phone on wifi with data disabled and I still got the battery drain.

Wifi is another issue, especially when you have the 5Ghz band enabled and your phone hops between both. Try checking if your Wifi's channel is crowded and configuring the router to another less crowded one.
Then force your phone to use either the 5Ghz or 2.4Ghz band depending on your setup; drain should've gone away.

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.

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
hey all
i use batterydrain app which to get battery % per hour
and always there peaks like 120% per hour and 60% randomly
and drain the battery significant
[ at first i thinked its cos the GPU, so i tested flash video, zooming moving and nothing cant make it peak to 60% BPH ]
but with airport mode there no peaks like that
the max i get is 30% the average is 22%
i don't get it
when i use GSM only and phone is idle i get mostly 0.1 BPH to 1 BPH
BPH - battery percent / Hour
really weird what is the problem guys ?
lets summarize
battery drain on idle [ gsm only ] = average 0.5% per hour
battery drain , browsing the net via wifi with gsm only = around 40-50%
battery drain ,airport ,browsing the net via wifi = 23%
23% + 0.5% != 40% doesn't make sense
sorry for my bad English
i will try it in bigger scale just put the sim in hd2 phone for while to see the different
Airplane mode disables the radios completely. Disabled radios = longer battery life + cooler phone.

THe radios are the main source of power draw and heat on the phone besides the CPU and display. By disabling the radios (Airplane Mode) you eliminate one of the major battery drainers, thus increasing your life and cooling the phone down

still not that much a different
if u see my drain at idle is around 0.5% per hour
so if u add
airport mode and idle u get = 22% + 0.5 which is much far then 40-50%
when gsm only and browsing the net

Dude, its simple, this is not rocket science. Airplane mode = less power draw. Plain and simple. Either take the correct answer or continue arguing about. Either way, you have your answer.

OK since that's over your head, take a look at this hypothetical situation. It's the same as asking why someone's car gets 90 hours per liter of fuel when its parked in a garage with the engine running, and but only 1 hour per liter of fuel when it is pulling a trailer full of obese illegal immigrants through the mountains in South America against a head wind.
It's because the car doesn't really use a lot of fuel when it's idling and doesn't have a load on it. But when someone puts a load behind the car, there's also other variables. Things such as high and low mountainous terrain, a bunch of really large, heavy people crammed into a trailer like sardines and then covered with old roofing shingles to disguise them are all things that require more power. Plus the resistance of the headwind along with the varying speed of travel and RPM of the motor that comes from having to slow down going downhill and speed up going up hill.
The moral of the story is, if you calculated your fuel consumption ahead of time and charged the passengers in the trailer at the rate of 90 litres per hour, you would be broke after one run for the border.
The car can't physically get the same efficiency sitting in that nice cold air conditioned garage as it can pulling that huge load which requires a lot of power, in extreme climates with changing atmospheric conditions and air density.
PS - Of course for the analogy to be complete, you would have to imagine that the gas guage uses a crap load of fuel to operate itself.
You get even better battery life if you turn your phone off. The battery can easily last a week or more! HTH! HAND!
I'd think your CPU and screen are using more battery than your GSM radio. When your phone is idling, your CPU can enter a power saving mode which greatly reduces battery usage vs being active while browsing. You should try browsing on GSM data vs browsing on Wifi data vs browsing on Wifi data with GSM active and see if you get similar results.
Guys, give him a break. This doesn't come easy to some people and it is our job to help them. Is that not why we are on these online forums? To help people?
Anyway, OP, think about it this way.
Your phone has to send a signal probably miles away to a tower. Walkie talkies have a rage of about 2 miles, and that is analog. Cell phones are digital, which requires more power.
Sending a constant signal miles away sucks a ton of power. Thus, by turning it off, you don't have the phone sending a signal a mile away anymore which reduces battery draw.

Great reply. I work in IT and it's really easy to forget a lot of people aren't technically inclined and to be condescending to them. If it weren't for the non-techies, people like me would be without a job.

The radio is still on and connected even if you're not sending anything.

WiFi uses less power than 4G, or even 3G, so it is better to be connected to WiFi instead of 3G or 4G if you can.
If you are on Verizon, than CDMA is only used for calling and texting, and 3G if you use it. If you disable mobile data in settings, it will cut off 3G and 4G, but you will still be able to make calls and use texting. This will greatly increase your battery life. Most people have a widget on their homescreen that will toggle mobile data with one tap.
The Rezound has a very small battery when considering what draws from it, 4G, 1.5 Ghz dual core processor, 4.3 inch screen. I you want better battery life you should take a look at the extended battery. Double the size, but seems like triple the screen time.
I bought the extended, and never looked back at the standard. Just doesn't last long enough.

Typing on the bus is impossible, especially with the freshman screaming and touching each other.
Oh, I need a car.....

The freshman on my bus aren't bad at all but I'm almost 16 so permit soon.
Doesn't the phone automatically turn mobile data (3G/4G) off when you're connected via wifi?
To the OP: The reason 23 + 0.5 != 40 is because you're assuming that all the battery usage is from the data connection / radios. But in fact the vast VAST majority is being used by the screen. And when you're making those radios work hard because you're browsing the internet, they're eating battery as well. So it's a double whammy. But when the phone is idle, the screen is off, the phone itself is operating as a lower frequency, and there's less data communication because it's only doing account/app syncs every so often instead of a constant connection.
And to you guys who were ripping on the OP for asking a perfectly valid question, let me response by quoting Ned Stark: Which one of you was a marksman at ten?
when someone ask out of the box/ system they cant understand and blame him for stupidity
