can i9000 power up without the battery inserted? - Galaxy S I9000 General

can i9000 power up without the battery inserted?

I'm assuming you mean without the battery when it is plugged into the wall or a USB socket?
I can't say for sure but I've never seen a mobile that does work this way and can't think why you want to (after all it is a mobile). Having said that, laptops do allow you to do this so I could be wrong.

why don't you find out ?
it's easy, just remove the battery, and plug in the power cord
try to turn on the phone
and the result is....

All Nokia phones ive had could power of without the battery.

What?! Nobody tried this?
It took me 1 min to try this on USB connction and power plug and it did NOT power up, so the battery needs to be inserted.

My Nexus One could do that.
I didn't try with my SGS.

my old HTC Athena will not work properly without battery using stock ROM
but if flashed with a custom ROM, then it can work without the battery.
I hope we can do the same with SGS
because using stock ROM is no go

This is a weird thread.
Why just don't try it yourself? As someone already pointed out, and I will include myself here, the answer is NO.
On a side note, my old HTC Hero could power up with no battery but I cannot see any use for that, unless you are hot swapping batteries and don't want to restart your device?

Experia: Battery status doesn´t update when inserting fully charged battery

Hi everybody,
I almost always managed to find answers on xda-developers to problems or wishes I had when tinkering with my phone.
Unfortunately, I haven't been able to find a solution for this one and hence my first post:
I always keep a fully charged spare battery with me just in case I run out of juice and I can't recharge.
However, when I exchange the run down battery by the full one, my battery status doesn't change and the phone switches off after a short while.
So far the only thing that works is briefly plugging in the phone with the replaced battery in it which will update battery status to 100% charge.
Obviously, this defeats the purpose of carrying a spare one around.
Is there a way I can force winmo to reset the battery status or another way to resolve it?
I don't mind if I have to rummage around in the registry if necessary.
Thanks in advance.

tat is the case with some batteries.. i have 3 batteries and only 1 that is acting that way.. all u need to do is carry a usb plug.. just plug it in when u are at work or anytin just for 30secs it will update to its full status.. or u can buy another battery so u get at least 2 battery that works..
Thanks Cutefox,
That sounds like a simple but effective solution.
I will try it next time I replace my battery.
the weird thing is that it does it with Ericsson's original battery.
Nevertheless, I may not always have such a plug on me.
There must be a trigger though when the USB plug is inserted.
If we know how WinMo recognises a USB plug has been inserted (maybe a switch in the registry), we can fool it into thinking it was inserted, and I wouldn't have to carry a plug around.
Any other suggestions?

nah.. its not about the plug.. its more of the voltage.. there is a trigger sumwer in the battery that switches on when you charged full. the thing is if you use a non-official charger like battery clip charger which im using, it is not as smart as the official SE charger/usb plug.. i think its due to the battery being charge outside of the phone too.. in the beginning it was always doing it so i thought my battery is faulty.. but after awhile, even charging it through the battery clip charger i sometimes come up with full battery.. so i got no idea why this happen.. another thing that could help is once u boot the phone up and it says its empty battery/low battery, do a software softreset.. that sometimes trigger the switch and turn on the true battery power for me.. only on stubborn times that i need to use the usb plug.
Thanks Cutefox.
I understand that in this case WinMo can't change the battery status without at least a minor external charge.
Let me ask you this. What eventually switches off the phone?
Is it the battery's power management chip that cuts further power to the phone, or does WinMo cut the power when the battery status reports 0% remaining charge.
In the letter case I could write a script telling WinMo to ignore the power warning for a predefined time, which should allow me to reach a power outlet.
i never tried tat b4.. but usually if its 0%.. there are times when i used xperia for extensively heavy usage and it suddenly shuts off on me while battery is still abt 20%.. i cant remember if its this battery as well.. since i always bring more than 2 battery it does not really bothers me as i got another battery to sustain.. but from what i recalled is not the windows mob status report warning that shuts it off.. more of the battery power itself..
Thanks Cutefox,
I guess I'll have to get one of those penlite powered emergency chargers to kickstart my battery for now.
In the mean time I'll continue looking for alternative solutions and report them here if I find them.
Does anybody else have ideas?
excuse my curiousity, but how the hell do you guys get the phone to stay on while you swap the battery? As soon as I take my battery out, even if the phone is in standby, it loses all power and cold boots upon putting it back in and powering on...just wondering as it sounds like a more viable option now to carry a spare batt!

of course you power the phone down in the first place before you swap it. you cannot swap it while its on. well u can and it will turn off but that is pure stuffing up the phone. never do it to any fone as per advised by a sony ericsson repair guy as it stuffed some of the IC chip inside. always power down before changing battery likewise any other electronic device..

Just keep it plugged in for 1-2 hours and then try booting in to try color screen bootloader and go from there.....
If you have MAGLDR installed then you can not charge the battery when the phone is off.
You should try to charge the battery using an external charger.
Edit: If you have a friend with HD2 and windows Mobile 6.5 then you could use the phone to charge you battery.
Wrong, you can charge it while it's off.

really? are you sure? because there are a lot of references to the magldr bug that wont allow charging (or even powering on without pulling the battery) if you try to charge with the phone turned off.
well i tried to charge for the last 2 hours nothing tried to remove battery nothing. Iam going to try and find a charged battery to see if the phone mite turn on or something. ill post later to let yall know what happen tho. thanks for the help.

what are you guys fighting about man, they just updated the magldr v1.3 and yeah we can now charge the phone while its off

Wrong x2.
1. No one is fighting.
2. With new magldr, phone turns itself on when plugged in. Charging when off is not possible. The battery requires management which is only implemented in software. It may hold a small charge if you have magldr installed, but it won't charge fully, or properly. Also, it's not likely he's got the new magldr if he's returning back to windows.
Lastly, for the OP, what method did you use to return to winmo? And which winmo rom did you use?

Read? Phone turns itself on if you connect a charger. Phone has NEVER charged while off with nand. This way at least you don't have to pull the battery to turn the phone on.
Sent from my HD2 NANDroid using XDA App
Just in case: If you on same situation that described on first post try this:
Q: If you completely run down the battery, would you be able to charge it with the phone again?
A: If your battery is dead, press and hold Vol Down and plug in USB cable / charger at same time. Phone will boot into bootloader and charge there just fine. Leave for 20 mins, pull battery, reboot and charge normally. If phone has just run down, plugging in the charger will usually turn it on.
Its found on one NAND thread and goals goes to g.lewarne
Actually i was on same situation and this helped on first try.
check the connection between battery and phone , the metal things i mean.
Perhaps, it is off the subject, but...
Poster #1: why do you want to get rid of this beautiful phone?
Just curious...
ok i bought another phone and i took out the charged battery from it and put it in the bricked HTC and it does nothing. now i know it was almost reverted back and i think the battery ran down but Iam not completely sure but maybe it could have been in the reverting software i used and maybe it just like lock up or something cause at that point you couldnt see the battery indicator. now i guess ill just have to sell on ebay for parts but it would be cool to try and un-brick it or try and figure it out.

Tutorial how to recharge phone when battery is drained!

So we all know the major problem with the WP7 roms.
You can not charge your phone when battery is completely drained!
Now here is the solotion. This requires no apps, no mods. Just your own handeling!
So what to do when battery depletes?
1. Plug your phone into a powersuply.
2. Turn on the phone and keep the power button and both volumes buttons pressed. (this is called a hard reset.)
How to hard reset HD2, view the first 17 seconds. Ignore the VolUp!.
3. You will receive an message saying:
''This operation will delete all your personal data, and reset all settings to manufacturer defailt. Press VolUp to restore manufacture default, or press other keys to cancel.''
Click to expand...
Click to collapse
4. Do not press anything. Let your phone be for a couple of minutes. I keep my phone laying for a minimum of 10 minutes.
You won't see the phone charging (no orange light in upper left corner)! Believe me it is!
5. After 10 minutes restart the phone. If ''press any other button to cancel'' does not work. Take out the battery, keep battery out for 5 seconds. Restart phone.
6. Phone will start. After windows phone loading screen you will see the phone is charging. If you kept it on power. If not, you didn't follow my instructions.
Tip: to avoid battery drainage!
When the phone is making the bleep noice warning for critical energy level, turn off the phone and keep it at a warm location. Ideal is to take out the battery and keep that to as warm as possible. Batterys barely drain when they are in warm enviorments.
I am not responsible to any damage done to the phone!
I done this multiple times, all times it worked fine for me!
If it helped, Thank me and leave a comment
when i'm on the road there is only one warm place i could think off, besides my armpits...
but your method works, have faced it once.
Thanks for the conformation.
To bad the HD2, is kinda big... doesnt sit that well.
magldr works as well
whats not clear is if the battery controler is in use with this method, so be warned, dont leave it too long, if you charge it for no more than an hour it will be ok
mains power adaptors usually give out 1Ah, take in to account that the screen is on full, this should give you around 700mA, more than enough to get in to windows to charge propperly
USB charge will be half that, most USB ports only give out 500mAh so an hour will give you approx 200mA again, thats enough to get you in to windows
Overcharging a battery can have some side effects, firstly is reversed polarity, meaning it wont take as much charge in the future, or it could heat up a lot, which isnt good for anything, the life of battery or the device its self.

That is true, but I recommend trying it for a minimum of 10 minutes keep it on charge. and as soon as windows pop on it recharges normally.
And didnt knew magldr did the job as well, the only problem is if you deplete it to badly it doesnt go past the HTC screen in the beginning.
all this is completely unnecessary.
easy fix solution:
1. Pull the battery out and USB cable out (if connected and charging)
2. Plug the USB into the phone and allow it to charge without a battery (it will not, duh!)
3. Put the battery in while the HD2's connected to the USB charging.
4. Observe that you can boot all the way back into WP7.
enjoy.

I did not know that.
Well thank you. Although I am not such a big fan of taking out the battery when its not needed. I mean the change is short circuits with the connecting points when taking out, when powered or putting in when powered it larger. Now I heared from a comment above that MAGLRD does the trick as well. Now that is far more easier then all the others given above, Yours and mine
good tutorial on this. I cant believe the battery wont charge when dead thought this was a faulty error of the phone.

theres 3 methods on here,
bootloader charge
magldr charge
remove battery charge
all three will benifit frm heating up the battery, do not cook it, or it may blow up
there is a 4th way but i dont recomend it unless nothing else works
take a usb cable mini or usb printer cable
cut off the end connector
strip back the wires and seperate them all, you want the red and black ones
make sure all the wires cant touch each other, cover the 2 unused wires with tape i
then connect the black wire to the (-) negative and the red wire to the (+) positive
tape them in place
the 3rd contact point on the battery isnt used in this method
finally connect the other end of the usb cable to the computer
dont leave it too long and when disconnecting remove the computer end first

It bypasses the system somewhat. Don't know what happens when battery is entirely drained, but it is worth a try.

If it does not help. You can buy a new battery.

Thanks for this timely post Lemonspeakers. completely drained the battery listening to music on loudspeaker and didnt hear any warning. Couldn't hard reset then checked this thread.
On putting in the battery after charging the empty phone, the screen kept cycling between mgldr and HTC splashscreen so booted into sd android and the phone is fine.
I assume I didnt charge the empty phone for long enough (30 secs), I didnt warm the battery and I suppose I could have left it cycling until it charged up a bit more.
Thanks again

That might work.
Otherwise maybe a phone repair shop, there is equipment that can charge your battery outside an phone. An emergency charger its called if I am not mistaken.
you could inform there.
its showing symtoms of it bring bricked. cause it doesnt charge, it doesnt turn on without the battery, and yeah conclusion is that its dead!

HD2 dead !!

Hey folks, i have a HD2 which isn't turning on. I received a call and it just switched off. Now there is no activity in it at all. No led when connected to a charger. I had MIUI installed on the phone.
The repair people say that the motherboard needs to be replaced which would cost approx 12000INR.
Any way i could revive it back?
Please suggest. Thank you!

You can try the the freezer trick, put the device in a zip lock bag and put it in the freezer for a few minutes and then see if you can turn it on or charge it. You can also take a old USB cable and cut the mico USB end off and strip the wires back then touch the read to the + on the battery and the black to the - on the battery for a minute or two and then try to boot the device. I sorta souds like you were using MAGLDR and the battery died. You can not charge the device while it is off with MAGLDR. So I would try charging the battery first.
Thank you for replying. You're right i was using Magdlr. I'll try what you said
Sent from my ST25i using Tapatalk 2
I've got the exact sam prob, the HD2 was using MAGLDR, and now it won't start (except for a few times it did), but I honestly can't figure how - since once it had been charged on an external batery charger, and then it turned on and worked for a while, but now it won't work with a charged battery...because I tried using it with another HD2 phone's battery which also has MAGLDR and which works (even with my phone's battery).
The pins have been changed, and it worked then also for a while I've been said, but it's not working again now.
Any help please?
TIA
P.S. I've tried ziplock...15min...nothing :/ How to try the USB? Which wires should I connect to which pins please?

or mini usb, or even an old usb printer cable, with the chunky end, , it doesn't matter which type.
Thanks samsamuel,
Seen the +/- signs on the back of the battery late, after having meassured the voltage, which is 4.14V (should I do the USB charge then even and how long is it safe since my battery powers up another HD2)?
TIA
if teh battery works in another device, then no, theres no point, its not that.
4.14 is fine, i think it goes up to about 4.2/4.3 when full, drops to the low 3.x when drained.
If the freezer trick didn't help either, then its gotta be either hardware, or something totally catastrophic, so if its an option for you, id try JTAG, failing that, id be considering using it for parts, , buying one with a cracked screen perhaps, and swapping your screen into it, ,
dont take my word for it, though, read learn and try things, you never know.

HD2 Help . Doesn't turn on

Hi,
So i Had this Htc HD2 . I got it as a gift from USA. I've used it like 2/3 month. I installed MIUI rom on this device. And then i hot another phone and didn't used that phone anymore. But today i found this phone and i tried to turn it on. Then I saw that the phone isnt turning on. It just stays black and just vibrates. I dont know what is wrong with this. I live in Bangladesh. We dont have any HTC customer service stores here. So i need help with this. If anyone can Help please let me know. and by the way its TMOUS HD2.
Check battery pins are contacting correctly.
Check battery voltage - lower than 3.2V try charging the battery externally & not in the HD2, if you do not have an external charger you can use a USB cable & cut mini/micro usb plug off then touch the red+ & black- wires to + - battery terminals for about 1 minute or bit longer if battery completely flat then put it back in HD2 & see if can boot.

Are you sure it's not just out of battery? If it had NAND Android installed on it via MAGLDR and you didn't bother turning it off then it could have just run out of charge. Since you can't charge the phone when it's off in MAGLDR, you'll have to cut open a USB cable which hopefully @samsamuel will come along and tell you about since I always forget what has to be connected where.
If you know it isn't the battery, then can you boot into the bootloader (hold vol down + power)? If you can get to that then you can try flashing a WinMo stock ROM to confirm it isn't some sort of hardware issue.

I wasnt sure if it was battery or not. And then i recharged the battery with a external charger and tried to turn it on. But no luck. it stays just the same. and i cant even get into boot loader (tri color screen). NO nothing. it just vibrates.
