Wifi issue

Sorry if this has already been covered in another forum.
My wifi on the samsung mesmerize is not working properly, 3G works just fine. I try and go online from my wifi connection it says server problem, if I go to my wifi settings it says it's connected. Help would be much appreciated, I have a very fast internet and would like to take advantage of it, especially considering my psu just blew on the pc! I have pulled 10 mbs on this phone using wifi before. Haven't installed a new app that would prevent anything with the wifi that I'm aware of, just wiped my phone the other day, saturday actually. Again any help would be great.

We're going to need to know what you're currently running.
As far as I know, no one is having issues with Wi-fi on either 2.1 or 2.2

My wifi sometimes won't turn on and I have to reboot to fix it, try that?

Yea if that don't fix it try pulling the battery.
Although since the phone is telling you i'ts connected I'm now thinking this is probably app related...(which a reinstall or reflash may correct)

I also have wifi issues with my fascinate, running froyo. I turn wifi on, and it works until the phone sleeps. Then at some point (seem to be a different amount of time each time) I lose my connection to the net. It still says the wifi is connected (wifi symbol at the top). But if I attempt to use google talk, or pull up a web page I do not have access to the internet. If i turn wifi off, and then right back on, all is well (until the next time it sleeps).
There is an app called wifi keep alive. If i check all the options on that app it helps. I see the issue far less often, but it still happens, and using this app my battery life suffers a little.

[Q] Rooting Other's Phones / GB Update

My Mom recently got the G2X per my advice, and is complaining about the battery. I can root her device, freeze bloatware, install juicedefender/setcpu, but since she lives out of town, I'm afraid if she wants to exchange the device, it would be difficult to talk her through the unrooting steps.
Should I wait for the GB update and hope the battery gets a major improvement w/o needing to root, or go ahead and root it?

One fix you could have your mom try is setting the network preference to WCDMA ONLY. If she is in an area that has good/great 4G coverage, she would not have to worry too much about it losing all bars and trying to reduce to 2G as it does by default when set to GSM/WCDMA AUTO.
It's goes against all logic because WCDMA ONLY (4G/3G only) should eat up more battery, but there seems to be some sort of bug that makes it conserve energy when not on auto and not trying to switch back and forth.
Again...maybe give it a try if she has good 4G coverage where she lives, works, plays etc. Since yesterday morning when I first tried this, my battery life went from an average of 5-6 hours, to an average of 12-14 hours. All with fairly heavy use of GPS, WIFI, Web, Calls etc.
Settings > Wireless & Networks > Mobile Networks > Network Mode > WCDMA ONLY. Reboot device....fingers crossed
Good Luck!!

Wait till GB is your best bet in that situation

I know I dont post on here often but ive had several android devices and this phone is the worst in battery life. Was getting 8 hours, max
What I did that helped was root the phone and inastalled setcpu and changed the default sync times of facebook weather bug e lite ect to two hours and finally I get a full days use. (16) hours or more I still have bluetooth wifi qnd gps on. I hope this helps.
Oh and I do toggle 4g / hspa and edge when I know I wont be around a charger this makes the battery last about 20 hours for me.

I'm assuming that's screen off correct?

I haven't rooted my phone neither have installed setcpu. I have installed only juice defender and I get more than a day of battery life. I used to get only 6 hours max before.

Set cpu manages the speed based on demand.
If your talking about battery time then its what I call moderate use of about 40 text and hour of talk time and glancing at engadget.mobile for a couple of minutes.
Not like today im using this thng like crazy and sitting at half battery now . Took off the charger ar 8 and its almost four now

Do you use SetCPU in conjunction with JuiceDefender, or should it be one or the other?

I am rooted but am running stock, I have juice defender installed and get a full day out of my battery. Unplug at 7am in the morning, moderate use during the day including games, txting, and gaming and then by the time i go to bed at around 11pm or so I am usually down to 20% or so. Juice defender is amazing. According to my battery stats I have been unplugged for 7hrs 27 mins and I am at 80%

Tmobile battery explanation

Thought you guys would get a LOL out of this... on my 3rd battery from tmobile trying to convince them to just send me a new phone.. told the rep it dies in 4 hours of idle time... His excuse "well that's because the G2x is a very powerful phone that does a lot of things so 4 hours is about normal." bahahaha nice try. new phone arrives tuesday.

I was told the same thing at the store after my 2nd replacement.
I feel bad for those who are not tech saavy and fall for that BS.

Was you phone rooted???
I had the same problem until I flashed a Rom and Kernel and now have 8hrs with Moderate use...

Rooted with cm7, tried battery calibration, turned off everything, no change.. Really think the phone is faulty

Talked to them about this today. I have been losing about 20% an hour while plugged into USB (while using the phone). They just read the steps the computer shows them.
First I was told that I need a task manager to kill apps I am not running. I was also told if I have a lot of apps that could cause this too. I mentioned that apps in memory aren't using the processor, and therefore not causing battery drain. I was then informed that having a lot of apps could cause the phone to run slowly. I mentioned I wasn't having issues with the phone running slow, but an issue with battery drain. They then told me that the processor has to work harder when there are stalls due to having many apps. I then asked why there was so much memory on the phone for apps, and mentioned that working in development myself, have no idea how this could be. There was no more discussion about this.
I was then asked how much I charge my phone. I said I charge it over night to full, and then while I am using at my desk I usually have it plugged in to the computer by USB when I use the phone, which equals to about half to 75% of the work day. I was told this was too much and there was no response when I mentioned again that this was during use and it was still draining. My only other option was to let the phone die.
A few more things to check and they finally said they were going to send out a new one, but that they were required to go through those trouble shooting steps first. At that point it is obvious they repeat what they are told.

More people need to emphasis this. I'm so very tired of 'tech support' telling folks to use task managers and killers on Android.

so far running cm7 and now cm7 xboarder v1.0.1, I am getting anywhere from 17-23 hours of battery life on a daily basis. I am texting throughout the day, regular phone calls with at least a 45 min call every noight and regular pandora use for around 5 hours a day. After rooting, my battery life tripled and then cm7 and its variants are making it even better. just my 2 cents

X boarder?

id say my battery life is pretty good, cm7 RC1 and fauxs kernel. lasts me all day maybe more. moderate use too.
Ehh whenever im at the t-mobile store and they're always speaking nonsense, complete idiots.

I spoke to an escalation Rep at LG and she told me LG is okay with 25% drain an hour. Ha! L

My pet theory concerns the charger. Did a battery swap and still had issues. This was the week the phone was released. Started using my hd2 chargers and have had zero issues since. In reality there are probably several issues, but this is what has worked for me.

make sure you guys turn off led notifications...kills the battery in no time

Any idea how to turn it off? Looked everywhere for that setting

Battery related...

Hi guys. I am the proud owner of a Galaxy S 2 Plus (GT-I9105/P). Wonderful device. I had no problems with it so far. It's an upgrade from Wave 2 Bada platform . But still can not believe how quickly the battery is depleted. To be more exact, when 3G is OFF, battery lasts about 3 days and when 3G is ON battery lasts no more than 15 hours. Can someone help me with this problem? I want that when 3G is switched ON the battery to last at least one day. Is there an app for this? Is there any setting that i should do? Mention that the phone is not root!

Try Factory Reset For Once I Am Sure It Will Solve The Problem

I did that by pressing vol down+power...no change . Is there any other way? Or should i try factory reset from Settings?

Yeah Try That From Setting I HOPE iT WORKS because Even I faced the same problem Bt Now its Battery Is Working Well

When not usung 3g try switching only to GSM mode instead of GSM/WCDMA drains battery a lot, for Me it does.
Specially when there is a poor network coverage.

This is the problem of 3G man.
Most of us allways work on 2G (enough for whatsapp, tapatalk, email, games, facebook, etc...) and we're online almost 3 days.
In 3G all of this change... (maximum 1 day)
How to fix it?... easy... we must wait for an custom kernel (with the correct governors and schedulers, we're able to support at last... 1 day and a half xD in 3G)
Or... you can change to 2G.
greetings from spain

I got pretty much the same:
-where I work there is very poor network coverage... whenever I have 3G on... battery lastes for about 1 day, while on 2G more then 2...

Huge battery eating when cell connected (Not data) - MM fw.163

Hello.
I don't know why, but since I bird this phone I got huge problems with battery life. Since the phone was LP-powered, it was hard to get more than 2h when using normally. Now I'm on MM, and with both Stock and Custom (RomAur) roms I can't get more than 3h. But the thing is, if I go into Airplane mode, my phone gets really good in battery. But if I only turn the data off, it still drain the battery...
I've heard of something called "fast dormancy" by another thread. Is it the problem ?
What should I do ?
Thanks in advance. Daniel aka. _cab13_

what I do before is I set my network type to GSM if I am not using the phone for internet (like if I am on wifi). try to see if this helps.
I think your problem has something to do with mobile radio active bug.

No it is not. Radio active bug is related to Data. But data is not the problem. It's cell and calls connection. If I turn my data off, it still eats battery, but if I start Airplane mode, it's okay

I installed BBS and it shows me that PowerManagerService.Display and PowerManagerService.WakeLocks are the most eating wakelocks...
Any idea ?
