[ROM-MOD]Radio Voltage Regulator (increase signal/save battery)
Hi all!
I am looking for a mod or software that will allow me to regulate the voltage amount to my Raphael's radio.
The idea:
- By increasing the voltage I increase reception/signal but use battery more (good for emergencies and areas with bad signal).
- By reducing the voltage in an area with great reception/signal I save battery power.
I am technically on the verge of developing it myself. I just wanted to check if there already is one before I do.
Also, any information that can help me get closer would be greatly appreciated.
great Idea, but it should be automaticly reactink by checking the reception, or when a intrnrt connection is build. otherwise it's not going to be much helpfull.
s.
Afaik, that should already be done by the phone itself...
@s.zamani
Yes an automatic mode is definably a must, I agree.
@Rumpel78
If it did, then why do I have areas with no signal or lost calls? and even if it did, I want to test how far past the default variable I can go. But I don't believe it does.
Can anyone confirm this?
Or point me in the right direction to read documentation on this?
With my old nokia phone battery drain was much higher with bad reception than within areas with good reception.
And at work we use Siemens and Telit GSM-Terminals where you can measure the supply-current is much higher if the reception is low.
I must check if this also applies to windows phones - but i cant think of a reason why not.
I will look into this.
@Rumpel78
Thanks for looking into that, that data will help.
Think of it like this though. Even if phones adjust power distribution to radio automatically... Manufacturers know (for example) that their radio can't take more than 1.2v (lets say). So to be safe they set a cap variance at 1.0v. Now obviously when its running at cap it will drain the battery quicker. However, there are times when even that is not enough and I can be stuck with whats known as 'no signal' or even get a 'dropped call'.
In other words, we would be "overclocking" the radio.
How would it be beneficial? while there are plenty reasons for one to have such control over their radio I will go with the obvious ones. Emergencies. What if I am stuck in an elevator with no emergency response? or am in an underground surgery facility and I want to text my family that a loved one came out of the surgery well?
Normally I would be in the hands of g-d or would have to wait until I surfaced and possibly even exited the hospital (respectively to the situation aforementioned)
It just happens to be in my life that flawless communications plays a big role. This is the main reason I am pursuing this. Even if minute, this type of control can come in handy if not life saving for some people.
This is assuming phones (and in-particular the raphael models) already are adjusting power distribution to radio based on a min and max (cap) variance.
If they aren't, this is a major improvement.
If they are this is a situational improvement, used deliberately in particular situations where, normally, communications would not be available.
I'm not trying to overcome cellphone signal jammers, but wouldn't it be nice if you could try?
Also I can think of another situation. Many countries enforce their own electronics safety policy.
So going along with my last post. What if the radio could take as much as 1.5v but was set at a cap of 1.0v because of electronic security policies of the country we live in?
In a situation of emergency, i don't care much for those policies and will use speaker-phone/headset for my safety.
This is so true that when we really need a good reception or even good enough signal to establish connection. Just once of your life time, it can be beneficial.

By that definition, I would like to specifically clarify, that I mean the part of the Radio that handles reception/signal and GPS. I see no need in adjusting voltage to sound or camera so unless someone specifically asks for it, that type of control will not be embedded.
P.S. Anyone who has knowledge in this field and can help me with the development please send me a PM as, at this point, I could use all the help I can get.

How about...
Windows Mobile Software Development
hm..
as others have already said... this is already done by the phone's internal hardware, and the radio ROM. maybe even some on the windows mobile side.
Also, based on the sort of questions you are asking, adjust radio amp voltage sounds like a bad place to start learning how to do windows app development...
This is really not needed. The best solutgion for the outer 3G ranges where the device keeps pinging. looking, for 3G service & hence burning through the battery faster is to turn off 3G in the Comm Manager. That way it is forced to use Edge or GPRS & won't bother at all looking for 3G. There is no way to amplify the device reception (short of an antennae in the car/home or integrated into a cowboy hat), So forget about that.
Just go into the Comm Manager or the Settings & simply select to not use 3G in or to use only GPRS/Edge in Network Settings. Either way will save battery & you don't really need 3G unless you are surfing heavy sites or downloading/uploading files.
is it a hardware issue? software problems?
I don't know how such a problem could persist for such a long amount of time, I really hope the Nexus S doesn't have this and I would likely shell out money for that (though the lack of HD video recording disturbs me)

Ever since JI6, the GPS has been able to "lock" in, but it gives terrible accuracy. It's accuracy that's important.
JK2 had choppy accuracy, JK6 made it slightly better. JL1 has been dead on for me, it even tracked my accuracy up to big bear (snow mountains in california). I went twice, once with JK2 or JK6 the first time, which sometimes listed me as off road during the trip, but when I went back with JL1, it went without a hitch.
I'm not familiar with these terms, but my accuracy has been fine, it's the speed which bugs me (takes as little as 10 seconds to as long as a whole minute before locking)
JK6? JK2? JL1? modem firmware?
Yep, modem firmware.

I agree, it is unnecessary and if this doesn't help consider an exchange.
Outstanding GPS Performance After Warranty Exchange!
I recently had to get a replacement phone from Tmobile due to a problem with the haptic feedback. I received a new (not refurbed) phone in original Samsung packaging with a mfg date of 10/20/10. The phone already had JI6 installed.
Since I've had good GPS performance on my previous Vibrant I was a little concernced about what might happen on an exchange. My concerns were definitely misplaced.
The new Vibrant's GPS locks up virtually instantly, faster than my old Vibrant ever did and with higher signal strength and more birds. I've used the navigation extensively and have yet to drop connection while navigating.
My first experience with the phone's GPS was by accident. We were shopping and I needed to get around a plugged freeway on surface streets I wasn't familiar with. I went into the Navigation app, spoke my destination and was INSTANTLY provided with my location and directions. Subsequent testing has also been 100%.
I've never seen GPS performance this fast and powerful with my previous Vibrant although it worked well enough to get me from point A to point B. The previous phone on occasion would take a minute or two to find my location.

These are typically rom build / version designators. The confusion comes from using these terms to refer to the individual components (kernel, baseband / modem, etc) that have been pulled from any given rom such as the modem. When the a proper context is present, it may not be too hard to tell how the terms are being used. That's not always the case though.

I realize now that Project Nero has JL1 already installed, so that's not it.
also, I have yet to see an answer to my question, what is the issue that causes the GPS to fail on these samsung vibrants?
If we truly knew, we would tell you. Or you would have searched and found the theory/answer(s).

JL1 was horrible for me. Constantly running on edge, and GPS sucked. Back to JK6 and everything is running great, back with strong 3G signal and GPS is acceptable (although accuracy is still off).
Best 2.1 modem JI6
Best 2.2 modem Jk6
Just my opinion

Samsung says the hardware is fine and that it is a software issue.
A few people believe it is quality control issues with the build of the vibrant (could be a loose connection and so forth)
so no one knows for sure, although most people do see changes depending on the software used, both for better and worse.
Not everyone seems to get the same results. (for some people, newer software fixes gps completely while for others it does nothing at all or makes things worse)
and then there are people that have had no real trouble from day one (they are rare, but there are some)
that's all anyone knows.
I think this question has been asked quite a few times already (there's even a few threads on this very page), you might check some of those threads for more info.

Probably multiple issues. Agps and status reporting were clearly busted originally, but that's fixed in later firmware. The accuracy issues on the other hand persist, for me anyway. Some people claim that they have no such problems, even with the exact same software, and if that's the case I can only assume sample variation in the hardware is to blame.

Do any of the available ROMs have optimal power consumption when tethering compared to others? Is there any way to crank down the Wifi strength so that the range is shorter but the battery lasts longer?
Thanks

I'd like to know this too. It doesn't seem necessary to have serve wifi from a phone at full strength, since the usage are usually done within limited range.

Yep, still looking for a solution...
Here is a ss..
any news on this? I also use stock rom and I wan't to control the wifi signal power.
Try this. (It is for stock 2.3.3 leak, not tested on 2.2.x). The settings are done in /system/etc/setwifi.sh, so you obviously need to make it run somehow on boot (like, via install-recovery.sh or whatever) or you are stuck with running it manually.
Flash from recovery (toggle signature verification first).
To test, just run this from terminal emulator (as root):
Code:
/system/xbin/iwconfig wlan0 txpower 16
(can replace the value with whatever you think will be best )
Just wanted to report, that flashable zip does seem to make WifiTxPower happier. I don't know if it's actually reducing the TX power but I'll find out next time I try tethering.
It really does seem to be working! Tethering to two devices with the screen off, at lowest power, it only used up 12% in the first hour.

I have seen many Threads regarding this. Some say it works some say it doesn't. Well it seems to save battery for me , but i have a question.. as it disables/enables your wifi and data(3G/4G) ..does it affect the hardware ..can it damage the hardware..the wifi/data adopters, etc.
From what I understand of it, being that jd runs in the background. As long as ur not a heavy user and u keep ur screen off most of the day. The system works. But as for damage, maybe. It gave me a load of connection issues. I still have some after I uninstalled. Even after an RUU to stock the issue still present. So, maybe. Maybe not

MAYBE !! .. sounds scary ..hahah ..dont want to brick my hardware due to the constatnt enabling/disabling ..now wondering if i shud disable it (i had bought the premium version)
You will get connection issues and very good batterylife. I'm hoping someone can find a solution for the issues by using a tweaked profile or another app. It is not harmful, just annoying. Any usage of your phone will shorten it's lifespan, and I don't think turning radios on and off is any worse than lets say your screen.
Sent from my GT-I9100
I have been using JD for over a year now on different handsets (Moto Milestone, HTC Desire, SGS2). The current version seems (mostly) stable and claims to extend my battery life by a factor of roughly 1.8. Hardware damages are unknown AFAIK. Connection issues can sometimes arise (very rarely & I don't know whether it's actually JD). Usually it restores a connection (3G or WLan) within 2-5 seconds which is fine by me. Note that connecting speed to eg WLan not only depends on JD or the phone itself but also on the router.
Earlier versions of JD did indeed have grave problems with restoring data connections. But this was around version 1.8 (I think). The current version 3.5 works just fine. Try the free version & if you like it I can only recommend the paid version. Once trained properly, the location aware switching of WLan works well.
(I'm in no way connected to JD, just a satisfied user.)
thx for the responses.. will start using it again.. it did save battery for me ..was just worried it might damage my radio hardware..

Well after the WOW effect wore off my phone, i am starting to HATE the flaws.
I bought this phone outright for a hefty $600 and hoping i did not waste my money switching over from blackberry.
MY problems
Bluetooth disconnects every 15 minutes, plus sounds like garbage, i did some reading on this and its a common problem yet appears to not be addressed yet? i am using a Jawbone Icon by the way and its dual connected to my work BB
Data(HSPDA) randomly disconnects at least once every 2 days and requires me to pull the battery to get it back going.
Battery drain is beyond crazy, i cant get 5 hours out of the phone with moderate use.
This thing heats up like crazy!!!
I know the last two things are software related, and people say upgrade to KG2, well my phone had 2.3.3 and KG2 and this is what it shipped with, so what should i go to?
Or can i just solve all of these issue by rooting the phone? if so, i will go that route.
Thanks.
Dustin
if you want to go that way(rooting,FLashing Roms)
Think twice, the SGS2 has a binary counter that counts how many times you flashed unofficial software on the phone,
if you brick it or something happens, screen breaks etc, you might ran into some problems @ samsung if they check the counter
you can reset it yourself by buying a JIG, google it!
I've had no issues with my bluetooth headset (logitech freepluse). i'd guess it doesnt like being dual connected
I've had no issues with losing my data connection (i did on galaxy s though). how strong is your signal before you lose it?
as for the battery drain, make sure you're exiting your apps + all the usual other stuff (turn off sync, wifi, bt, set to autobrightness). 2.3.3 does have the drainage issue for some people. i'm on villainrom 2.3.4 and have no drainage issues
rooting won't help you out.
HSDPA disconnects? if you have H always on that means you are either downloading or uploading something most of the time, H only turns on when there is data being pulled or sent, you should see the 3G icon MOST of the time, if you are streaming music/video then you'll see the H kicking in.
I have a Jawbone Cruiser and have no issues whatsoever I have 2 devices paired to it but only 1 at a time, A2DP works flawless and it even sounds better than the original Galaxy S.

Rooting will not solve these issues, but I can maybe enable you to start solving it.
However, before you start messing with kernels and firmwares I would really try to find out if some of the problems might be hardware related or not. If so, you could use your warranty to get a new one or get it fixed. Once you start messing with custom software you're never sure if they will grant you the warranty or not.

not sure where you get that from? i actually hate apple and take that post as quite an insult, one and only thing i ever owned from them was a ipod way back, and it got stolen 2 mths after i bought it and i never replaced it.
that aside, i came from a Blackberry Curve 8330, although it sucked, it did have good bluetooth connectivity,decent battery life, and did not heat up, keep in mind it was a CDMA phone.
so i know i have some changes to expect with a new network, but it appears lots of these have been fixed by people and i am just trying to understand the software and device, KG2 KY this,etc is all new to me, so i have been reading lots but find it confusing since its so vast.
needless to say it will be kind of disappointing if i cant connect 2 devices to my jawbone icon at the same time and work flawless, as this is huge for me.
Also i NEVER see 3G data show up on my phone, its always the H with up and down arrows, should i see 3G? im up in Canada(Saskatchewan to be exact)
It appears i should update from KG2, yet KIES shows no update, i have not dove into Odin to try that out, maybe i should?
Any help is greatly appreciated.
Thanks.

Rooting doesn't solve anything, just gives you access to hidden files. You need to flash a newer rom(kh3 or kh5) and hope it fixes those issues.
I agree with the above poster, I've been using android since inception and I don't believe in rooting a phone to mask the issues you are having, upgrade the software, there are many roms to choose from, get the device running well before you think about rooting.
People are giving new android users the impression that rooting is the answer for phone issues, it is not.
Rooting is for advanced users who want the extra access to explore the power of android.

I don't understand why everyone seems to be pushing the USB JIG, it's like there are people making and selling them here or something.
@BrokenPixel, H or H+ doesn't drop to 3G as fast, if your Telco doesn't support Fast Dormancy, or you have Fast Dormancy disabled.
I like Blackberries, it is lacking as a end-user smartphone, however for companies, I still like the privacy with point to point encryption. Android does not have that unless you purchase a 3rd party application which means both parties have to have it as well. Again, it really depends on what you are using the phone for. I still recommend using the right tools for the right job.
@Gustopher, calling Blackberries a "second cousin of a minor demon..." is like calling a screwdriver the bane of our existence, or a hammer "the killer of thumbs..."
peachpuff is correct, instead of rooting your phone, perhaps you should try changing the modem to something else instead, try KH3, KG6, KF4, KE4. Perhaps in the mentioned order. It really covers most regions, since we don't know where you are at!

If your problems are related to your settings, flashing newer firmware (KG5 for example, works fine with me) will only really help if you do a complete wipe/factory reset. See the guides for that.
That would be done best by rooting with CF-root, going into CWM-recovery, doing a backup there, do all "wipes", reboot straight into download mode and flash the fresh firmware via Odin. The guides are all there.
Just make sure to play with some settings like gsm/wcdma in your network settings first.

Have you never heard of BB's? He came from a Curve..basically a glorified pager. He could probably go 3 days on that thing with a single charge. Kind of like going from a Commodore 64 to a high end laptop.
One thing I haven't heard mentioned about rooting is the fact with root you can install Titanium Backup..and with the Pro version..freeze apps (instead of deleting) which allows you to fiddle with perhaps some rogue apps that are draining your battery.
As usual with most Androids..make sure you don't have FB or Twitter syncing crazily (and if you're running multiple tweet or FB programs..be sure they aren't syncing as well). I'm not familiar with Touchwiz..but if they have their own "social networking" apps that you don't use (and you use the actual apps themselves instead) be sure to check those and make sure they arent sync'ing either (and better yet freeze them with TiBu).
