Network 3G and H swapping problems...

Hi
I have this problem and i think ive come across a few people with the same frustration.
Which is the constant switching of our galaxy s fone networks frm 3g to H.... Happens so constantly it disrupts and keeps me in limbo so many tyms i cnt even tether properly with this problem!!!!
Please olease is there any fix for this out? Ive looked everywher!!!!! And if not. . . please as a humble request can a dev please create something so that only H frequencies are chosen and are prioritized so that it doesn switch to 3g please?????

Ha.
Yeah mine does too sometimes.
A way I get past it is to tap back button and select again and it quickly loads up in h.

Could be a problem with XXJVS radio? I go back to XXJVR to compare results.

HSDPA is an extension of 3g. It uses the same frequency. The reason it is switching is to save power for better battery life. It switches to H when you are using the connection, but than switches back to plain 3g when it is idle.

Mate. What's with your logs obsession????
Too much hassle to log. Hardly ever happens and when it does its an easy fix.

user experience is well problematic
one will see 3g changing to H and call it a bug or so =)
i belive only on what is there in logs

Yes ofcourse its an extension from 3G to H .... But i am still using the dam network n it still keeps changing to 3g and H is there no way to keep it on one of em?

That's just how dataconnection works. .if you want to keep your connection in H-mode constantly, you need to make your phone to ping something for every 3 seconds...like ping -t 3 8.8.8.8 in windows (if I remembered it correctly).
In short: connection is in H-mode as long there is traffic. .

In my experience (from reading stuff here and observing my phone) it seemed that constant switching between H and 3G drains battery faster than if we could force the phone to use only H. From your post, I understand this is not the case. I never thought that 'switching' was a battery save feature...

I'm using CM7, and although it switches to 3G for a short period of time very infrequently, most of the time I have an 'H' displayed, even when it's idle. I also don't notice any significant battery drain. Maybe my phone is just crazy, though.

I've had this since day 1 with my phone, through many different roms... it's frustrating as all hell and really hurts my battery life and my patience

The switching from 3G to H is not the problem and not the cause of the problem here - it's just the symptom.
It's because data is lagging and stalling further upstream, so the phone is simply returning to idle as it should.
The solution is to change carriers to something that gives more reliable data.

Take a look at http://forum.xda-developers.com/showthread.php?t=837716 for a guide to disable HSDPA for better battery life.

Very useful info .... I asked for a solution to stay on H i get a reply to disable to SAVE battery life which is clearly not most the prioritized issue here... But thank u.... Any one else with a solution to either stay on H or 3G????
i had a sony x10 mini pro and problems were similar... But then from control panel i selected 3G only ( only options were 2G and 3G) and when it was onnit it NEVER gave up H ... Constantly stayed onnit so if its possible on a fne **** that m preetty sure we cn do it on a galaxy s

Wouldn't the most likely cause of your phone switching back and forth be because you're losing connection? My phone stays in H when I need it, and leaves it when it doesn't. So...

Nope i have constant network on full bars... Keeps working only until the H starts swapping is the time my phone enters limbo and i lose connectivity

The problem is that it literally hangs between 3g and H changing constantly without loading anything. If I say for example on xda, touch a thread and it does this, it may stay in a changing to and fro for minutes and not load. But if I select thread again as soon as it starts doing it it opens to thread quickly and normal.

Battery drain with 3g on terrible

Hi guys,
Is anyone else get terrible battery life with 3g and data on even on standby? I believe the phone function drains the battery and it lasts only 2 days or so on standby. I constantly have the tab on flight mode with wifi enabled and battery is much improved to about 1 week standby. Anyone else? I am on stock 4.0.4.
Thanks

Wtf r this guy even serious? I wish i had 1 day standby, what a joke

Hi Iong. We are talking about a tablet here, not a phone. Tablets should have 1 week standby at least. The battery drain with 3g and phone on is unacceptable. I think the reason is the connection to phone signal which is constant.

Mate 1 day pr 2 day standby is a lot, given the fact you install many program and it constantly connect to tinternet to check for updates notifs etx. You dont have 1 week standby whatsover, forget it. Big tablet big baterry big screen. Ot all goes scaling together

So 'l2_hsic' and 'batt_work wake lock' are the 2 processes keeping my table awake for 5 hours in total since yesterday. Any idea of what these do?
Thanks

tcdscr places
most likely is that one or more of your apps is causing the problem. try a reset and see if the problem goes away. if it does, install apps one by and and check which one is the problem

Use juice defender ultimate in tablet mode. I can go several days idle time and lose almost no battery.

Still having issues

I'm still having huge battery issues no matter the ROM and kernel I use...
I have tried looking at battery apps that determine what's sucking up the battery but half the time it just says screen or WiFi. So it got me thinking, is it WiFi? I leave WiFi on, which was never and issue like a month ago or ever on my previous androids...but now all the sudden it seems to be the cause? I woke up to find my phone at 50% from 100 within 5 hours...of no use just WiFi turned on and set to only stay on when plugged in...so I could really use some help guys...

Simple solution - turn Wi-Fi off and see if it fixes the battery issue. Possible it is but to draw 50% that quick you'd have to be far away from the Wireless AP. In most cases that's very unlikely.

ya look at that.....but when you have small charges in between that dosent fully charge you.... you can make it run for ever...... the timer dosent reset untill you hit full charge. i agree with garwynn but ide also check your battery for swelling. ive had my wifi on all day (didnt realize it) and ive not had but mabey a 15% drain from it (5h28m to be exact).

Phone Idle Battery Drain (Deep sleeping & no wakelocks)

Does anyone know why this is happening? My phone deep sleeps but loses ~10% per hour. I tried replacing the battery and restoring to stock but nada

uuuhmmmmmm quite weird... I think that must be a hw issue.. did u contact google? does this happen with every kernel?

I got my phone from a carrier in Canada and they will not honour the warranty because I bought it outright. I have tested stock and franco

Install BetterBatteryStats and see what the other wakelocks are.
Sometimes WakelockDetector does not show every wakelock that is happening.

And look what i said, WKD does not seem to be able to see all the wakelocks, install BBS and see if you get any extra wakelocks.
If that doesn't help, i would suggest you to do a complete reflash to stock and see if it still happens on stock.

turn off your wifi when you are not using it. there is a constant drain with a wifi connection.

Drain is STILL there with wifi and everything off (airplane mode)
I installed BetterBatteryStats and everything seems normal. In a 1 hour period the largest offender was msm_hsic_host and sns_async_evwakelock and suspend_backoff with a total of 4 min.
It seems to drain the same whether I use the phone or not.

Anyone have any ideas? Here is more info

I was after a red light I bought a new battery because I wanted everything back. but after replacing. the phone loses all the time very fast.i think is battery fault. I tried all the ROM and the kernel and does not help

Seems like the exact same issue. Have you tried using another battery? I am being sent another battery to replace the one I bought so I will try that when it arrives.

I not tried yet. I wait for the 4.4 ROM and if not help i buy new battery but from someone else

I have a question. as you put the batteries you put blue tape too? It's a bit strange but maybe this is the reason because I threw my to the trash.it is called blue anti-electrostatic discharge tape

What blue tape? Do you are exepriencing usb connection problems too? I have all those symptoms after I've replaced my battery, and also the usb stopped working

I doubt the tape is the issue.
Have any of you tried using another new battery?

Battery issues....

So I'll start off by saying my battery only lasts 8-10 hours from 100% to dead. So fair I have pinpointed the issue but I don't know how to fix it. I'm using an at&t d800
When my WiFi is on, no or unknown signal and no data connection start ticking and killing my battery. If I never turn my WiFi on my battery will last 19 hour or more.
Has anyone less encountered this issue and/or know how to fix this.
I have had this on bone stock 10o and on gravios rls 4.
Please I really would like to use my ac router and to get better battery life.
Thanks for your time.

get betterbatterystats and look into wakelocks, check kernel, then partial and google the living daylight
turn wifi off when no signal, not that complicated really.
lobby with your provider for better coverage in your area.

all of that dont work, then warrantee, or get an Iphone so you dont need to worry about silly wakelocks and unfriendly way of managing phone that Android requires

lol, just bring it back to a lg dealer
if that doesn't work, buy replacement battery, there are threads here how to open the phone.
or root it, twrp recovery it, wipe the bagesus ( not the sd card) out of it. so its clean. Then reinstall stock or good custom.
then condition battery, a couple times full charge down to zero and up again.

LG Dealer? also its not the battery not holding a charge its if my wifi is on the battery drains like crazy because my phone thinks there is no siganl so its boosting the cellular radio. with out wifi on it doesnt do that so the battery lasts a long time.

well good news it is software related. i installed cm 11 and wifi on is not causing the no signal wake lock.

Conditioning is only good for Ni-Mh battery's but bad for Li-Poly battery's. (which g2 uses) 0% and 100% are bad for them. The best is to charge them from about 10% to 95% if possible.

I dont understand why my battery if I charge it past 100% grants me an hour longer screen on time. I did notice a different span when using till 50 and then charging it again. Once I went from 100 to zero and back up it seemed it reset itself.
weird battery I guess.

Bad calibration is all. Its that magic 1% @100 and crap 5% bottom end. Noticeable across all devices. Evens itself out, never ends. Seems at 100% starting, its not really fully charged.

actually it doesnt cause all that does is lose network when network reception is low. It doesnt affect battery like your battery is affected.
