"Stay Healthy" GUIDE - 2G, EDGE, 3G, whateverG

An issue not much spoken of around PDA enthusiasts is health.
after Menneisyys's most wonderful guide on how to switch between networks I would like to develop his idea in another direction which regards to your brain staying cool.
btw, here's a reference to Menneisyys's guide.
http://forum.xda-developers.com/showthread.php?t=345524
As cellular generations evolved we got the gift of fast transfer rates.
This of course, doesn't come for free, and the higher the transfer rate, the more our brain boils.. whether we're connected to the internet or not.
This is not ALWAYS true, but let's assume that the 1 in 30 cases state is negligible.
In most cases, when you're connected to the 2G network, your device will consume less battery power than when it's connected to the 3G network.
We can refer to 2G,2.5G,2.75G,3G,3.5G.. and so forth. the main issue is not the EXACT difference between these network types but how much does each of them effect your brain.
Our devices' batteries consume power. they also radiate Electromagnetic waves which, if were visible, would create a most complex web, preventing us from doing anything since we would not be able to see.
that wasn't true in the past. the amount of energy radiated was much much much lower.
When you're connected to the 2G network, for instance, your phone tries to retain a fluent connection between its receiver and the (usually) closest relay point. this requires power. this power is also reflected into your brain.. and while a small % of it is dissipated into the air, a lot of it creates unnatural (we'll leave it at that) heat in your brain. it's something like the heat emitted from laptops (which you should also keep a good distance from.. using coolers and stuff.. or you'll get all kinds of pains.. like i have right now typing this on my laptop).
Every provider plants relay points in different places.
though it's a common belief that those relays are not healthy for you and you'd want them as far away as possible.. i'd say you don't.
it's true that having a relay 15-25m away from your window isn't exactly a vladnik carnival but there's a certain distance from the relay in which your phone wouldn't work too hard to retain a signal, and the relay (edit: not the actual relay but the effects caused by having a close relay) won't keep your neurons busy until they burst. It is obviously impossible to individually control the distance.
As 2G and 3G have different requirements, they also have different power consumption. It doesn't require much more than common logic to understand that since 3G needs to transfer more data during a short period of time, it would use more resources than 2G, which needs less during the same period.
As an introduction to the concept of "power" i'll begin by saying that 2G requires something about 3-5 times less the power to keep a live connection than 3G does. as it's not completely true, it wouldn't be wrong to say that 3G creates about 3-5 times the heat than 2G does. a fireball to your brain.
Rough numbers are averaging from 0.043mW/kb in 2G to 0.23mW/kb in 3G.. while using EDGE for instance... is much closer to 2G than to 3G.
Power dissipates by 1/r^2, r being the distance, so i'd say it's certainly fitting to use a headset rather than talking straight to your device.
of course, the best thing to do is to use your speaker.
1. You will be wise using 2G only for phone calls and use your speaker as much as you can to keep yourself away from long lasting brain damage.
2. You will be wise to use NOT MORE than the EXACT data connection you need for your applications. (i.e. if EDGE is fast enough for you, DON'T use 3G)
3. Actually, you will be wise NEVER to use 3G... but that's a bit hard for people who download porn on their devices and want 1.8-14.2MBPS
4. Cancer isn't a joke. BELIEVE me..
5. Cancer isn't a joke.
I'll finish by helping you understand how bad the whole issue is.

the power formula is P=I*V
in the 2G case, P=0.091*3.9=0.355W
in the 3G case, P=0.239*3.9=0.93W
the relative power is 0.93/0.355 = 2.62
this means that at my house, where there is almost maximum signal strength, 3G requires about 2.6 times the power 2G requires.
these are really rough numbers as the current also contains other factors... but you can see the general ratio.
now when the signal is low, 3G requires like 3-4 times more than required when there's a strong signal.. but 2G only requires like twice.. maybe less.. since it has a much lower transfer rate.
it is true that this is the power used and not the radiated power.. and it's true that there's distance between the battery and your brain.. but roughly..
3G is HORRIBLE. don't kill yourselves. use your phones. wisely.
- never use more than 2G unless required. 2G supplies EVERYTHING you need but video calls and internet services at the same quality.
- never use more than EDGE unless required. EDGE supplies about 300kbps which is good for surfing..
- never use 3G unless you really need a very fast connection.
you are invited to use the below tools to check how your phone acts.
Hope this helps you realize what's good for you.
EDIT: now just to clarify this issue so that i don't get clobbered, i am NOT refering to electromagnetic waves THEMSELVES (thus canceling the effect of distant electromagnetic radiation emitting devices). all i am refering to is the heat generated by your device. electromagnetic waves have yet to be proven harmful since their frequencies are too high to harm us(that's the current assumption). the heat generated by those waves tho, is known to "fry". that is, and as i mentioned before, like the heat generated from your laptop which causes inflammations.. and .. other things.
There IS a link between the electromagnetic radiation to the heat generated in our body as the higher the frequency, the higher the particle velocity, causing higher friction which causes heat. this effect is negligible when discussing distant electronic devices, since, as i said ealier, power dissipates by 1/r^2.
what i'm trying to say is, that whether it is proven you can be harmed from electromagnetic radiation and heat or not, we should just be cautious. just in case..

Well.... first of all I do not agree on all your points or think everything you say is as serious a factor as you describe it to be. However, I'll not 'bicker and argue' on these points, less radiation is always better, after all.
In fact, you just gave me an idea for an awesome new app, I may or may not write soon
The whole reason for my reply however is this simply tip that will make a lot of difference for a fair number of people, I'll bet:
Do NOT place the phone next to your head next to your bed when you go to sleep!
This was actually in the news here either past week or the week before that. Seeing as you'd be in that position for like 8 hours, you can see how it can make a difference

You are correct. this isn't as bad as i made it sound. but making something sound worse than it is always makes people take it more seriously.
I would say that the problem isn't really in the short run.
In the long run, it can be devastating.
and you're right. it's a good tip to not leave the phone close to your head while sleeping.
this actually creates unwanted brain activity. again, in the short run.. it doesn't really matter.. but having more current going thru your brain EVERY night.. will damage it.
and by all means.. argue. this is a forum after all

Surely it's your gonads that are in more peril from 3G as I don't surf/videocall with the phone against my head?

I guess yeah your gonads may be in trouble
Personally I don't even have phones in the same room as where I sleep, and whenever I'm not walking somewhere they aren't on me either. In the car they're either on the passengers seat or in the glove-box, and at home or work they are in their desktop cradles
Dont carry them on you unless you have to.

Interesting read...nir36!
One thing is for sure, numbers don't lie. As you know, my thread question whether 3G is worth it on a battery front, but more importantly on a health front.
It would be great to get an APP to allow Communication Manager to speak to the different Networks (2G, 2.75/Edge, 3G, 3.5G, etc.) in order to give back power to the people...instead of power going to their heads!
Yes, I know people use the internet away from their heads but most use the 3G network for phone calls. I don't......switch to Edge immediately.
As mention previously, it would be great to have a "Network Switcher" allowing users to make wise choices.

I leave my data connection running downloading stuff a lot of times when I am at work. I have found I can amp the juice down a LOT by turning on my speakers and listening to the crazy noise then moving the phone to a spot where the noise goes away or gets very quiet. For instance. On my desk they go crazy. If I put the phone on the window they go silent very where as moving it in the other direction the same distance does nothing. My conclusion? my head and the speakers which are only about 2 feet away from my head are getting much less radiation. Can do the same thing with my headset for a more accurate placement BUT for some reason it barely picks up the signal to begin with. Not to mention the cold metal window sill cools the phone! bit torrent gets the lil bugger warm.

hey and what if i disable GSM module for night? i use my pda also as alarm clock so is it also so dangerous when it is disabled but still near my head when i am sleeping?

if Phone, Wifi, and Bluetooth are off in the wireless menu I cant see of any reason it would emit any radiation. Unless someone else knows something I don't.

Putting it in "flight mode" would indeed kill 99% of all radiation.

as Chainfire said.. it would kill about 99% of the radiation.. or even more.
radiation levels are caused mostly by the fact that you have an antenna fixed in your device which emits EM waves heretically while the phone is on. when the Bluetooth, Wireless and Phone are off... the device only runs on a few mA... while in sleep mode... so the heat levels are dissipated at about 0.05 (or so) cm from the battery. even if you put your phone right next to your ear while all comm services are off.. there's almost 0 chance that something would happen.
to answer your question... a pda in flight mode acting as an alarm clock can be placed next to you. still, just in case.. keep it 20cm from your head.

Wouldn't it be great if a manufactuer built a phone with a small parabolic reflector behind the antenna that very quickly rotated based on the direction of the tower. Increased battery life. Increased signal. Decreased radiation through your head. Sounds difficult at first but when you think about it, it would be pretty easy and cheap.

great idea... but what would happen if the closest tower created a straight course between the middle of your brain and the device?

Just a bump (as people should read this topic!) and a good spot for some shameless plugging (spam police where art thou?):

I did spend some time on cooking something up that will reduce power usage for GSM-based devices when you're not 'manually' using the data connection. Not nearly done yet, but I have to be off for the weekend so it'll be a bit longer too.
When it's done it will result in your brain (and gonads!) being cooked less, as well as longer battery life. So longer life for both you and your battery - you may place your bets on what it will be called now!

I think it will be called, "Chainfire's Gonad Savior"

Nope, wrong guess, and here it is (pre-alpha, proof of concept): http://forum.xda-developers.com/showthread.php?t=478519

lol. good idea. if only we had x-ray vision

Given that the OP here mentions cancer and 'brain boiling' and all sorts of other horrific stuff but doesn't appear to have any real science backing these claims up, isn't this thread just rampant scare-mongering?

Its highly overstated to make a point. This just proves you didn't get that point
Besides, how radiation works and what it can do is widely known. If you have to provide scientific proof of every widely known thing whenver you talk about it ...

wired tether?

If wired tether was working on any of the roms would the phone run hot. If I use wireless tether for much more than about 30-40 mins its crazy hot.

I guess this hasn't been addressed enough. *Cough* Search *Cough*
The Wired tether app, though loosely based on our phones pieces, doesn't work for us. We think the commands it uses are wrong.
The MNS stuff works in 2.1 Roms for some people.
Your phone wouldn't get hot. The phone gets hot now due to the battery having to run both the CDMA Radio and the WiFi Radio and the processor for the phone, its a lot of strain on the battery which = heat. Using MNS or Wired tether is like you were syncing and can actually charge the battery while you use it as opposed to loseing battery power like WiFi Tether.

How to tether Sprint Hero
I thought this was posted here. i found this info a few days ago but i forgot where, so if your the source or you know it just let me know.
\Steps to do wired tether with sprint hero (i dont think root is required)
Step 1 - Go to Settings>Wireless Controls and take of Mobile Network
Step 2 - Go to Settings>Wireless Control>Mobile Network Settings>Mode of operation Change this to 1x ONLY
Step 3 - Go back to Settings>Wireless Controls and Turn on Mobile Network and Mobile Network Sharing (in windows it ask for driver, the htc sync drivers will work posted below)
Step 4 - Check connectivity by going to a web site.
Step 5 - To get EVDO working just go back to Settings>Wireless Controls>Mobile Network Settings and change Mode of operation to Hybrid and EVDO should come up.
Step 6 - Enjoy the EVDO tether
I am pretty sure that it doesn't use phone as modem. i don't have that service and it works.
If you get Error 67, it probably because the phone is in evdo mode, must be in 1x to initiate connection.
also phone doesn't get hot.

That's the MNS race condition. It doesn't use PAM, but it is a ***** to time just right.

i havent had many issues timing it, i just do them one after the other. when im in the car on my way to AC from NYC i have rev a the whole way down. its nice.

although i will say this is the 3rd/4th thread about this (I made the first, and am always asking about it in the dev threads)

[Q] Wireless tether speed slow(er)

Im wondering if anyone noticed a speed difference between wireless tether speedtest.net results and the speedtest app results?
Im able to get 20-25mbps on the app but only 5-8mbps down when tethered to my fairly new laptop. Im wondering if there is a remedy to this, kernal or whatever or if it has to do to the fact that its connecting on G instead of N.
Dont get me wrong, 5-8 is pretty fast but if I can get more than 2x that speed by doing something different I want to do something different.
Thanks
Brandon

I am experiencing the same slow down.

Don't forget the wifi card in your laptops can make a huge difference. Remember that Wireless G tops out at ~13Mb/s. I was able to get the "full" 13Mb/s on my laptop though that is only G. If I had a wireless N card I'm sure the numbers would be the same as the speedtest app.

Stop believing the Speedtest app, go to the actual website on your phone and do the speedtest from there. That will show your actual speeds.

It has been stated for a while now that the speedtest app is inaccurate with LTE

still getting much better results in the browser. 15-20 down
Ive had no trouble getting high speed tests on other networks with the card in this laptop either.
The little sticker in the lower right corner says I have a Acer Nplify 802.11b/g/n and Im only connecting on G, so I guess im only broadcasting on g.
The tether I downloaded was on googles website.
The one in the market isnt showing up for me.

And the whole internet isn't run off of that server. You got that speed, from that test, on that server, on that site, at that exact time. That doesn't mean you are going to get that for everything. It's a speedTEST, keyword... test.
Yes, VZW has blocked the viewing of any wireless tethering apps in the market. Because they don't want anyone tethering if they aren't paying for it. And after the free trial Mobile Hotspot is up on the 15th of it is up they may be monitoring it much more closely.

yea sure, but shouldnt testing that same server through the same connection yield similar results?
I can test it from my phone and then my computer or visa versa and consistently get lower results on my computer.
Also im wondering why its broadcasting on g instead of n
If you say it will only broadcast on g then Ill just take that but on my dink I would always get consistent results when doing this test

Really? Don't get me wrong but if you can post a picture of a transfer rate of 54Mb/s I would gladly retract my statement.
That's like saying you get 300Mb/s on N, just because it's rated at that, doesn't mean thats what you actually get. Under perfectly ideal conditions, a wireless G connection will get you ~25Mb/s...thats perfectly ideal. Now take into consideration not sitting within 5 inches of the router, other wireless frequencies in the air, and plenty of other things in the air to disrupt the path of the wave, and you get a "ideal" 13Mb/s.
Nonetheless, the new speedtest app did fix the upload issues with the massive send buffer of the thunderbolt, so they are as accurate as the web version is.

As for this you will always get more consistent results from a landline as it is a fixed connection, and is always connected to the same host (your isp). Your phone on the other hand is always going to be vastly different especially when you select different servers to test your speed with. Some servers I get almost 30Mb/s, others I top out around 9-10...it all depends on a lot of things.
All in all your speed shouldn't be a big issue with tethering unless you are torrenting which god help us all you better not be
For general browsing, anything over 5Mb/s will be hard for the general user to see a difference in. If I had to put a surefire number on my throughput on tethering, I get around 1.5MB/s on LTE, which is equal to my comcast line in my apartment.
As stated earlier, wireless G is 2.4Ghz which is a high frequency. High frequency waves have a much lower skin depth than lower frequency waves (such as LTE running 700Mhz). This means that the waves will be much more susceptible to things in its path such as your body
If you are getting at least 5-8Mb/s on your tether, you should be happy. Think of where you were before on 3g

I actually just had the same issue, WiFi tether only yielded 3-5 mbit down. On WiFi mobile hotspot I got 11-13 mbit down, so I believe there is something going on.
Sent from my ADR6400L using XDA App

I'm wirelessly tethered right now, ran a speed test on my laptop and the browser on my phone, and got almost identical numbers. 10Mb/s Down and 1.2Mb/s Up.

I've been saying this for a while.
Even on Easy Tether (wired USB connection) on laptop and desktop I'm getting 3 down 1.5 up. Verified on Speed Test sites and actually downloading files.
When I first got the phone (Mar. 18th) I could use Easy Tether OR Wifi hotspot and get the same LTE speeds I got on my phone (using the site, not the app).

Terrible Tether Speeds
I bought this TB specifically to tether and my tether speeds are about 1/10th that of the phone speeds. On the phone I get ~8m/13m however on PC and I tried 3 including windows 7 and xp i get ~1.2m/800k. So let me ask a couple of questions.
1. I used the speedtest.net app how much can it be off? I will try the website and see if its that much different.
2. This is a new phone and the software status is blank is this normal.
3. It was explained to me that my area is a 4g EXT area and not native which they said may cause a difference (but how can that be if the phone has good speeds).
Is there anything I can do? If not i'm sending it back.

Same story here, large slow down on wireless tethering.
Barnacle and Wireless Tether for Root Users act similarly. Running the pre-alpha CM7 (RC0.6) on my Bolt.
Perhaps there is some kernel optimizations needed for this type of "pass through"?

Just wanted to reiterate that the speedtest app is innaccurate to say the least. If you run the app you will get far different numbers than if you go to speedtest.net via the browser. Also I'm assuming everyone is giving these results on 4G? If not, we need to set the bar a little higher

Use this site for your metrics:

I've found speedtest.net to be grossly inaccurate.

Unusable WiFi

The wife and I just switched to Sprint and got two GS5's. Her wifi access is tolerable, she can play a youtube video. I can barely even load a facebook feed. My wifi is total garbage, so I went and installed wifi fixer:
https://play.google.com/store/apps/details?id=org.wahtod.wififixer
And the alerts say that it's constantly having to reassociate the Wifi. Even with this in the background fixing things up, I can't use my wifi. I also googled the problem a lot, and found that someone manually switching the IP type to a manual IP gave them better luck. Did not help me out.
The Sprint Spark data is incredible, it actually beats my home broadband internet. But I'm in the basement so I can't just use my data :'(
Background on the phone, BOTH are stock out of the box rom, but with TWRP, Root, 4 Way Reboot Menu, and unlocked hotspot flashes.

What WiFi setting are you using and what model router?

Before I tried the setting on the advanced it was stock out of the box DHCP, then I switched it to Static to lock an IP, with little difference. Back to DHCP for now.
I can ask for better details because the router is in someone else's room, but it's the one that Century Link (DSL ) Gave us.

LMAO LOOK AT YOUR LINK SPEED. THAT IS TERRIBLE ALMOST NON EXSISTENT. You need to modify some settings or add a capable router to that. Here is what a decent link speed looks like on this device and this device is capable of more than this.

To add to my previous post is my guess that WiFi you currently have is not mimo meaning multiple people can't be connected at the same time with sufficient link speeds. Your wife was the first to connect and it is giving her 90% of the link speed which is why she can and you cant. Only a new router can correct this more than likely. You can disconnect everyone else from the WiFi toggle your WiFi off then on and go check your link speed with no one else connected just you and I'm gonna guess you will have around 5 MBPS link speed. FYI on link speed it's not that you need a huge number for the link speed to browse the Internet but a minimal of 30 MBPS is needed to have an ideal Web experience especially when it comes to viewing images on Web pages.

I know that century link is worthless but I doubt it's the problem. I can stream youtube, Hulu and all that kinda stuff pretty decently on my laptop, decently on the wife's phone, worthless on my phone. Any hour, when everyone is asleep, I still have a piece of ****.
Last night I remembered that when I did the hotspot unlock I accidently did the NC1 or whatever it is Hotspot fix file, then corrected it to be the ND2 file. So I went and fully reloaded the phone back with the stock TWRP backup and didn't help

Oh I'm sorry, I thought that's what the link speed was referring to. We used to have cable but our neighborhood doesn't have new cabling or something so they can't work here.
It's just weird and frustrating that it's just MY phone. The other 4 GS5's in the house do fine.

Link speed is from the WiFi router itself. what happens is your WiFi starts at (for example) 52 MBPS with one device connected. Then that gets split each time a new device connects. When you have a new router that's more capable it does not split the link speed as much with each connected device. Link speed is the speed in which the device is communicating with the WiFi router
,

My phone gets 5, the wife's gets 117. My best I've gotten was 39mbps on this phone, but at 4AM when everyone is asleep I still only get 5mbps.

You can try forgetting the WiFi network then add it back and see if that makes any difference

Also, check whether the router supports 5 GHz over 2.4. If so, try switching to that.
You may find with the cable wireless gateways that you're better off buying your own.
Comcast's isn't bad but get more than 10 feet away and you start seeing it drop off.

Wifi problems

has anybody else had WiFi problems with their 7pro? I had WiFi problems with my 6t as well it'll say connected no internet and the Wi-Fi is very slow opposed to data when there is no other problem with other devices using the same Wi-Fi connection. sometimes the Wi-Fi won't work at all even if my phone says it's connected apps will not load. I am on a t-mobile variant flashed to international since the day I bought it a week ago any insight to this would be great because I see that people have this issue a lotk

Yeah WiFi "speeds" on the 7Pro are abysmal. I have around 1/3rd to 1/4th the speed compared to my previous 5T. Something completely unexpected, thought the phone would be as least as fast if not faster.
Same thing on 9.5.5/9.5.7 and with various kernels

Yeah I'll vouch for that too. My WiFi speeds and connection strength for that matter are terrible! I came from a 6T that honestly had no problem with WiFi whatsoever, so this is annoying. Well, I hope the next update addresses WiFi, because the 7 Pro is a nice phone! It's a shame!

Add me as another for this list. My speeds are absolute crap, seemingly capped at 15mbps across all networks I've tried. My sons Pixel 3 on the other hand flies on the same. So not a router or ISP issue. So disappointed as everything about the 7 Pro is awesome but can't live with such poor WiFi, have a feeling it affects the HotSpot capability and speed too whatever the issue is.

Hi all!
I had that too - a simple wipe cache of all the phone's resources fixes the problem (turn off the phone then hold volume down and power button till the recovery mode kicks in and then just go to wipe cache and reboot, e voila!). I had some 10 MBps (lol!), now it is almost 80 Mbps, which is what I should get given my old WiFi system. Never settle!

Along with wiping the cache as the previous poster said...another thing that sometimes works is to reboot your router while at the same time doing a network reset on the phone. This way all the connections are fresh and new. I know this has been a solution for many different phones over the years. YMMV

T-mobile variant flashed to International
Same problem here. I have the T-Mobile variant and flashed international prior to 40 day unlock. It shows I have WiFi and or data but nothing loads. I rest my phone and all is good. It happens 2-3 times a day. I've tried wiping cache and it still happens. I vaguely remember having network issues before I flashed the international software but, I'm not sure if it's the T-mobile variant phone or if its international software. Any ideas?

Are you sure it's the phone?

seeing as i have now tried multiple locations and wifi's yes. and my work phone can connect just fine to all the ones including my home, just the oneplus can not.
it stopped while in use like it just died.

Does anyone know how to solve this issue yet? Can't seem to find any fix

I wonder why I got this slow, I used to have 100+ on my old iPhone X (same 5g wifi)

My wife and I both have this problem as well. Fortunately we have truly unlimited data, or tie would be unacceptable. Sometimes it's super fast, sometimes it's so slow apps decide you're offline. I've never seen any sort of fix; it's probably an OS/kernel level issue.

Same issue!!!
I have also created thread on onePlus official forum!

In Houston, I have no wifi issues with my 7pro on ATT!!!!

Router settings are going to play into this. Many variables beyond "my phone doesn't work" I can get over 200mbps on a fast router and connection properly configured for N or AC. Even on 2.4ghz, 60-100mbps works.

I just got this phone coming from a Poco F1 that decided to stop charging unless turned off and I've gotta say that this is very disappointing. First problem was that the phone wouldn't go above 10 Mbps. Changed my AC router config from 80 Mhz to 40 Mhz and that helped increase it to > 100 Mbps but if I go into Wifi settings the max the phone ever sees as receive/transmit speeds is 192 Mbps. It doesn't matter if it's 5 Ghz or 2.4 Ghz. Tried changing settings in the router and even tried a different router, same thing. Reset network settings, same thing. Reset the entire phone, same thing. This is the t-mobile unlocked variant of the phone.
Is there anything that can be done? Would a custom rom or converting it to the international version help?
EDIT: lol this is clearly either a hardware issue or some OS limit. I enabled hotspot and connected my Poco to it and the Poco also sees 192 Mbps max. This sucks...

I have the same problem with my op7P.
after downloading and installed an update, my WiFi could not be detected anymore....
it just could not find any WiFi
Needless to say, hotspot also failed.

I was able to fix my above problem (stuck at 192 Mbps max) by switching to the Pixel Experience ROM. Unfortunately, battery drain was excessive (and fingerprint stopped working out of the blue) so rolled back with MSM tool and upgraded to 10.3.3 using local upgrade. Back to stuck at 192 Mbps so this is definitely a rom problem.

I never had wifi problems with mine OP7 pro. Maybe a router problem!
I'm using 5Ghz and wifi rocks on Op7p.
