Hi guys,
Since I made the mistake of switching to DUO instead of the Tilt (yeah cast stones on me) when I updated "that one" to 6.1 the /WINDOWS file incredibly messed up. So much so that I felt a hard reset would work and reinstall 6.1 but instead I killed it on "Download Ready". Now I have to turn in my lil' POS to Pantech so they do that themselves. Bummer and no phone for 2 weeks.
Then I pull out my good ol' trusty Wizard but this one, unless I have it plugged in or hooked on the USB, it powers off and on constantly and goes back to original config (year 2006, and such). I NEED this phone as a loaner till I get the other one back. No use to have a cell phone that you can't use without cables.
I want to know if there is a fix to this, or if you guys think if updating this dinosaur (original everything, OS, WM, radio, etc.) to your latest and best(est) would fix this really annoying thing. Heck if you guys can fix this I might put the Duo in the corner for a while after it comes back...I got that SIM card and put it here and I can make and receive calls, the problem is it turning off and on constantly and deleting everything.
Now I will go back to my corner with my straightjacket. Thanks!
Hello there fellow Wizard owner. This is my first post on the website and I think I can help you out.
1) Try and leave your Wizard connected to the wall outlet for 1 hour. Then turn it on while plugged to the wall. See it will reboot. If it doesn't unplug it and see how long it lasts without it being plugged. If it reboots when it is unplogged it could mean your battery wont hold it's charge no more and all you need to do is get a new one. I went thru the same trouble last month and after testing everything under the sun I decided to replace the baterry and .. Viola!!! no more reboots for me.
I hope this helps.
Another questinon,
My notebook is Vista; my DH's is an XP. Which OS is safer to perform these changes? I found the thread where I can update the OS and to WM6 for newbies and I will try that first on XP.
One of (if not) the main reason the Duo got screwed up is that I tried to update it to 6.1 on Vista, when I was supposed to do this on XP (but don't tell anybody that they had TWO different instructions for BOTH OS's).
Cheerio.
Lol ... Yeah on my personal opinion if you are upgrading your Operating system use XP ... for some reason Vista freezes on me. And b4 you upgrade remember to read ALL the threads about upgrading your Wizard. Pretty much you can find all the answers on the search engine. And this guys are close to Gods when it comes to modding this "dinnosaour". I have pretty much messed my phone over 100 times .. I always look for the newer Rom and hacks and they guides they have here can help you with almost any known problem.
I know...I have taken apart mine FOUR TIMES and put it back together...two times b/c my daughter decided to dunk it in OJ!!!!!!!
Good thx for the advice I will fetch for a batt then...my DH will not hear me complain any longer I hope...
It's more than likely your battery.
When mine went - from a full charge to 60 % no issues, once it hit 59 % charge - the phone would cycle on and off until I pulled the battery - or stuck in back on the charger.
New battery - haven't had an issue since
Good luck

Hi,
Performed experiment as we agreed...turned it on @3pm (let it charge for more than 1 hr) and AS LONG AS I DID NOT MAKE A CALL it worked fine. Now it is having those seizures again. I can only stop it by taking the battery off, of course if I want to do that immediately. I dialed, when I was gonna send a page to my DH it went bipolar.
Now that is a reason why I believe it is not necessarily a battery issue but a software/hardware issue. I believe I will try upgrade software on this thing.

Did yours did this when making a call? I played games, fussed with the calendar, updated email settings, but nothing happened till I dialed.
Yep - usually when making a call.
Games, settings, etc take very little battery power - but phone calls take the brunt of the battery power.
Kind of like when they give you battery ratings - you will see four or five days of stand by time - but only 5 hours of talk time.
Like I said, for me - it was the battery.
Good luck
Same here battery was my problem. But if you still want to try to update. Make sure you charge the thone THRU wall adaptor then thru USB. If I remember correctly wizards wont charge a completely drained battery thru USB. And if during the update your phone starts to do the reboot dance it is 99.9% your batery then. Again GL.
Hi,
I have now had 2 occasions where my LG OX2 were automatically shut!!
I took it of the charger this morning, screen brightened, all normal. After 5 min. when I needed it, the phone was off. Later I had one more like this. Got to work and after some hours it was off when I needed it! I really don't get it. Battery was full.
I am on 2.2.2, rootet.
Has anyone had same experince??
I had that issue aswell.
Had that aswell yesterday morning, had to take the batteri out and put it back in, to get it back on
Same here.
Hi guys. Thanks for your answers. This is indeed very strange. This could be something that I will not accept for a smartphone this price. I will contact LG.
Are yours also rootet and have you removed anything?
Cheers.
Rooted. Not removed anything at all.
You mentioned that you have rooted the phone, did you freeze any applications?
Same here.
Only happened once and it was plugged into a charger (and would have been at 100%).
Battery pull was the only thing that worked.
I'll add this thread to the bugs thread.
Have not happend to me yet. I have used it for 1 day now. And 3 charges. No problems.
Rooted and deleted some apps.

Nope.

So it seems to happens just on the rooted phones. Maybe the root its not stable yet?
No, i have not yet roted and i had the same problem yesterday. Nothing so far today though.
Optimus S ... same problem!
It seems like Optimus S have the same problem
Here a link :
http://forum.androidcentral.com/lg-optimus-s/47567-phone-shuts-off-when-charging.html
Mine is not rooted, I had around 54% battery when I left work. Phone rebooted two times during the 15min walk home, once during a call and once when all I was doing was swiping around the homescreens... :/
My o2x rebooted once today, with 50% battery left.. Edit: Mine is also rooted and I have frozen the car home app.
This is very distressing. Being that this problem affects the 2x, rooted or not, then it is def. a hardware issue. Possibly solely a battery issue, or the design to which where the battery is housed (connectors), or simply power hit/miss circuitry design. My advice is, if it occurs enough not to annoy you (meaning, you don't want to deal w/ a return/exchange & don't mind the re-booting) then keep it. I believe that no software patch can fix this & for such an expensive device, I would return it for a fresh unit.

I did withnis this twice yesterday.
The phone doesn't shut down. It is a huge lag.
It happend the 3th time. I didn't pull out the battery, after 20sec that I pressed the power button for the screen to light up, the screen showed.
So it is lagg.
Not rooted. And to make it clear i'm talking about the phone screen not turning on, so you have to pull out battery and power it on again. No reboot.
What?! 20s lag? I was looking forward for quick device since I switch my Rhodium for LGO2X. I hope that this would be fixed soon by LG...
How odd. I haven't experienced this at all, and i've rooted mine and removed apps like F-Secure from my phone (By renaming them, don't worry.)
I guess a good way to find out if it's lag is to see if adb is still working.
Had it yesterday myself, once during charging. Then the powerbutton did work. Hour later I had to pull the battery. Wanted to advanced but forgot to leave USB debugging on. Had it so far only with my replaced unit. The first few days with the original unit didn't show signs of this...
Have to say my first unit wasn't rooted until the day they swapped it. The one I have now has been rooted since day one.

Hi all,
Firstly, thank you all for providing so many answers to my many noob-questions, even before me asking them! This forum is great.
So, my setup is visible as the first attachment to this post.
Previously, I have had lots of problems with the battery only lasting 5 hours, but I have finally come across a good config of kernel, ROM and apps that have boosted that considerably. Also, I keep WiFi turned off, apps bckground syncing off, GPS off and accounting syncing off. DarkyROM rules!
And, my running services are really few (see second attachment), and I'm getting some really good battery times now (see third and fourth attachment)
And, here is my question to the forum:
I have realised that a) when the battery drops below 50%, AND b) the display is set to time-out at 15 seconds, THEN the phone shuts off, and I can see that the battery seems to have died. Please see the third attachment to this post! Does anyone have an idea what is going on, and how to resolve it?
Thanks so much for any constructive answers!

Did you try wiping battery stats in recovery mode? You could even try recalibrating. Do a search for "calibrate battery" in XDA forums.
i had the random shut down issue, after i contacted the support center they thought it was a battery app. Do you have any battery monitor apps? If so, uninstall all of them.
For me that didnt solve anything, i had to get a replacement phone. If you are still within your 1 year, i would highly suggest doing the same. Now that i got this new phone my battery life has been amazing. With the original unit it used to be tops 12 hours, now i can get 1.5 days!

sadly, my phone is more than a year
Try these things :
# Replace Battery
OR
# Resoft , reset battery,recalibrate
Try battery calibration or charge it 100% and then flash the rom and see. If this is one not helping you. I think you have to change the battery.
Try Juwe's Smart Edition !

Not the best idea!
This is happening on Juwe's ROM v5.2 JVQ.
I had a freeze after exiting a game called Paradise Island (I get that quite often!) and then I had to press the power key for 9 seconds for the phone to reboot itself.
And, NO, that charging on the graph isn't an actual charging, the battery just recalibrates itself over time. Strange!

HI
My wife has my old Touch Diamond2. She complains that after charging it overnight, the battery shows as FULL, but within a few hours it is dsicharged.
1. Does the battery need replacing
2. How can I check to confirm it is the battery and not the charger/phone.

Thanks Senax for the nice link.. That is very nice thread to read and understand

I think the phone possibly has a hardware fault.
It strange, because if I take the simm out the phone keeps alomost full charge for the whole day!!
Not sure if its worth fixing.

May be you can check what all kind of networks are working/used when SIM is in? Also make the network selection Manual instead of AUTO and see the difference.

recently I did two changes...
I Flashed the last radio
I Flashed the last Photon UX Room.
And then I fixed the battery problem...
why? I don´t know
lfallasm...
Thanks lfallasm and TD2IN
I dont want to flash the phone cos I have software (TomTOm) on the phone for which I no longer have the original CD to re-install. Also I have never flashed before.
I will try the network selection suggestion.
cheers
Network selection is already set to Manual.
I noticed something very STRANGE today.
I thought it maybe due to the signal in the new house we moved to, so I took the phone to work. Made one call and it went dead. Tried to start the phone, but battery to weak.
I took the sim out. started the phone without the sim and HEY PRESTO, battery is 75% full!!
Any ideas whats going on??
You should really flash it first, and if it fails you have a faulty phone. But flash it with HTC stock Rom, because you will lose waranty if you use anything else.
Its out of warranty. (My wife uses this phone now)
Would a FACTORY reset achieve the same as flashing with a HTC stock rom??
regards
FIXED.
The battery was faulty.
Apparently is had developed a slight "buldge" in the middle. Probably due to over heating.
Bought a new battery and all seems well.
£8 battery saved me buying a wildfire S for the wife.
Hi
Can see a number of threads about short battery life, none quite match mine:
When I got the phone about 6 months ago I took it abroad with me in the first few weeks. Battery life with normal usage was about 24 to 36 hours with fair use.
Dropped the phone, back came off, battery fell out and gold contacts got damaged.
Ordered replacement OE battery from Amazon. Looks identical to original. Battery life as before, for about the first two weeks. Then got worse and worse until down to about 4 hours. Sent it back, replaced. Replacement is going the same way.
Haven't done anything with the ROM, it's all as it originally was, albeit I've installed more apps since it was new.
Battery meter thing built into the phone (in Settings) shows nothing remarkable.
What is odd, and coincidental: if I leave the phone next to me in the house, it won't always pick up emails on ActiveSync (Exchange) unless I activate it (e.g. bring it out of power down mode). At which point you can see it's dropped Wi-Fi. The icon has gone. A second or two later it reconnects (though not before it's used some 3G data - 3G is OK upstairs, barely a signal downstairs as we live at the bottom of a hill so often drops to "G") and then brings down the emails.
This means it churns through 500MB+ of data over its own 3G connection in a month even if I don't take it out of the house, and even when Wi-Fi is available to it, it chooses not to use it. Wi-Fi reception is pretty poor, compared with e.g. our laptop (that shows excellent strength downstairs, phone shows one bar). It did not do this when I first got it. Curiously my old HTC phone did this too, it struggled to switch properly between its own 3G and Wi-Fi and just got stuck on one or the other. We are in a weak signal area.
Are these things related?
Has the phone become faulty? (Bearing in mind battery life much better with the original one)
Is it just a duff batch of batteries and I should send the battery back for a refund, and get one somewhere else?
Thanks
Mark
Typical behavior for a counterfeit battery but the other symptoms suggest that something got damaged and is stressing the battery. Try re flashing the phone. A sudden loss of power could potentially damage some system files.
Thanks rogem_kk - can I just clarify, when you say "reflashing the phone" do you mean resetting it back to its original state (I'm guessing there's a key sequence you press, I can look in the manual to find that out) or completely reloading the OS?
As regards "sudden loss of power" sadly this happens quite often, because the phone crashes now and again and I have to take the battery off the back and put it back in again. The Android OS seems able to be completely taken down by a failing application (I think Flash movies on web pages are the main culprits) quite readily but I'd got very used to that since my last phone was a Windows Mobile one (the old one not the new one) which had the stability of a damp cardboard box in a strong wind.
I mean wiping it clean and installing the ROM from scratch. Factory reset only removes your data and does not restore/replace system files.
Now may be a great time to flash a custom rom, if it all goes well then do a back up with Nitrality app or similar, while you're at it try out a modem i9000 ZSJPG, you can flash it separately via ClockWorkMod, doubled my battery usage with it, great reception & coverage, that way if you at least get a genuine SGS battery you'll get the most from it.
If you're unsure of flashing you'll need to get reading in the rom section, not too hard to learn.
Many thanks.
Down to 3 hours idle time now - it drops by the day.
Have emailed Samsung on the off-chance they can identify a counterfeit battery from the serial number, so I'll see what they say. Could make for an interesting exchange with Amazon (direct, not via a reseller or third party).
Argos appear to be the "official" resellers for Samsung products in our area but they don't actually sell batteries. As otherwise I'd be tempted to buy one there on the basis that it ought to be genuine, and compare. But haven't rebuilt the phone yet, waiting to see what Samsung come back with.
Hmmm...
"Problems like this, although seemingly severe, can occur when the
Android software on your phone becomes out of date. You can update the
software by simply downloading our Samsung Kies programme. Follow the
link below and choose option ‘save’. Then for safe installation of the
drivers, once save is complete, turn your computer off for a few minutes
and reboot the PC. Once fully loaded again, without opening any
applications on the computer, simply connect your phone to the PC with
the USB lead, and your phone should be automatically set you finish the
installation of Kies. When Kies loads and finds your device, you should
be offered an update that will iron out these issues.
If you require any further assistance, please contact Samsung again and
we will be more than happy to help."
I had one of those so called 'original batties' it was a load of rubbish. Still using original one but its no holding charge for as well after a year of use. Maybe time for a real replacement...

Forgive the curtness of the email, am at work typing one handed while chowing down lunch
First point - you dropped your phone. I know that the new battery went okay for a while but is it possible that the phone itself may have been damaged?
Secondly, Email on Activesync over 3g will absolutely smash the hell out of your battery. Especially if you have push email going. Is it on push or is it set to check every so-and-so amount of time? Too short a period will kill the battery. The "Stock" email app that comes with Gingerbread 2.3.3 or lower seems to be just a big hog over push (for me at least). I also recommend changing the email "Amount To Sync" to a shorter number of days and set the amount of data to a lower value than stock (ie, "Headers Only" or 50k or something) so you download attachments on **your** terms.
Thirdly, you state you're in a poor reception area. This will most definitely affect the battery as the phone on a low signal or zero signal will waste battery trying to reconnect to the tower. Check your "Cell Standby" and see how muck time without connection you have. If it's anything above nothing, it's draining your battery. I recommend flashing a new modem (you'll need to investigate which one is good for your region/country/carrier) through ODIN (or Heimdall). Be careful when doing this and make sure you read up on the hows and what-to-do and what-not-to-do before you do - there is a (small) chance of you killing your phone and I do *not* want you to come back onto this thread and say it blew up (I want you to say "YAY THANKS WOGFELLA" ) Doing this voids your warranty so only do it if you either don't care or you really really want to fix your issue (and by default you don't care)
Fourthly, your wifi coming on and off - go to your Wifi settings, press your menu button and click ... advanced? Can't recall exactly (on ICS now). From there you can set your "Wifi Sleep Policy" to either "Never" or the other option that I can't recall. The default is set to turn the Wifi off when screen is off which of course means you lose your Wifi connection. **For your Email issue, try this first.**
Fifthly, your Wifi signal being weak in your display does not *always* equate to an actual poor connection. Sammy does many great things, but he does mess about a bit with icons and funny business. Check step four above and if you get bad Wifi reception when the phone is off (or while using it) then try messing about with your Router settings and also with the settings on your phone (take notes before doing so, I'm just throwing you ideas here....don't come back to me and ask me how to reset your router settings either!!!)
If that doesn't help then try flashing a custom kernel (kernel controls the Wifi). As above, doing this will void your warranty.
Sixthly, you say that everything was hunky dory and then went haywire. I reckon there may be an app doing funky things.
Try installing CPUSpy from the market and check to ensure your phone is going into decently long periods of "Deep Sleep"
Also, try installing the below app from this thread.
http://forum.xda-developers.com/showthread.php?t=1179809
You're looking for high "Wakelocks" which will impact on your phone being awake instead of...well, asleep...when the screen goes off. Awake phone = cpu processing (even if it's not doing anything) = battery drain. Use Chamonix's recommendations on what is classed as a high amount of wakelock.
Facebook 1.7 for example, keeps the phone awake while checking notifications that just plain ain't there. For me, once I wiped this app, I regained about an extra 2-4 hours per day in use.
Seventhly, look over this thread:
http://forum.xda-developers.com/showthread.php?t=939752
Has a heap of tips that helped me (before I got sick of stock Sammy and jumped to CM7 and then ICS)
Eighthly, and this is one that probably doesn't need to be said - cycle your battery and (controversial) bump charge. I mean, let the battery drain fully. Take the battery out for 5 mins. Put it back in and see if it turns on, and if it does repeat. Then fully charge to 100% and then unplug and plug back in. If your phone is already rooted then you can also wipe Battery Stats from Recovery.
Lastly - have you tried factory resetting your phone? It may wipe whatever it is that's making your phone freak out (if not the email) and you can start again. If you find that the battery goes bananas again after installing that app, you've found your issue.
So...to sum up:
Check your phone contacts.
Check your Wifi sleep policy.
Check your Email update rate.
Check the length of time you have the sync set for,
and the amount of data per email downloading.
Check to see if you are going into deep sleep.
Check to see if there are any apps holding wakelock (and bugger them off)
More extreme:
Factory reset.
Mess with your router settings if your wifi signal is still weak.
Very Extreme.
Flash Modem
Flash Kernel.
One thing not specified: What version Android are you running? SGS comes from Eclair up to (once Cyanogen and TeamHackSung get it rolling properly) Ice Cream Sandwich.
Hopefully *SOMETHING* in the above helps you.
Good luck!
Thanks for taking the time.
Sorted out the Wi-Fi sleep issue, CPU Spy showed the phone was going into deep sleep when idle, so no "smoking gun" discovered with that.
Reset phone, and set it back up again with basic email and no new installed apps. Have left it on default (minimal) donwload settings. Had already got rid of Facebook.
Battery life is better. Have begun reinstalling a few apps now and keeping an eye on it.
Will report back - thanks again all.

No dramas - just be careful as CPU Spy will show length of time in deep sleep but a high proportion of wakelocks won't really be detected and those wakelocks are the ones that smash your battery when sitting "idle"
As you have reset then I think you need to let your battery calibrate first (let it drain fully and recharge fully a few times and that's all you can do if you haven't rooted your phone)
.. one more update..
Battery life is better, but not much better. It still won't last a day without charge even with very light use, 7 hours is about the maximum. I'm certain it used to be better than that when I got it e.g. it survived a whole day on holiday using email and maps quite a bit.
Have changed to 3 from O2 but will have to revert back as 3 doesn't get a signal at all downstairs in some parts of the house. Does mean the phone is going on and off network a lot at the moment.
I reverted to Samsung to tell them their link didn't work and they have sent a link to an authorised dealer for parts if I wanted to buy another battery. I'm all for buying the real thing which is why I bought an (apparently) OE one from Amazon which was about £16 not the £5 that some were.
However this is, er, forty four pounds for a tiny little battery.
http://www.4mysamsung.co.uk/cgi-bin/product.pl?PID=2986318&brand=&model=galaxy s&part=
They also sent links to repair centres.
Now I plugged it into charge earlier, and even after 8 hours, it was dead. Plugged it in again - beeps once as normal - nothing on the display - still not charging. Take battery out, put back in, repeat. Charging now.
Might make you wonder if that part of the phone got damaged e.g. the "socket" where the mini USB thing/charger goes in, but, it's always worked before. It doesn't for instance fail to detect if I plug into the PC and it's never done this before either.
Given how much the battery is and the fact it might be getting to the point of dying altogether I wonder whether to just get a quote for repair and go that way for certainty.
One might have thought it's as simple as: take the thing somewhere and have the battery tested to prove one way or the other.. but I'm really not sure where would do that other than the repair place.
I'd be prepared to try replacing the OS as suggested, but it does remain the fact that the thing worked better when I first got it and even after a complete reset it's still playing up so I feel a sort of mental paralysis over what's best to do now
I'll have a look at the wakelocks thing next when it charges again. If it charges
