Connect the charger without battery

Is it possible to connect charger without battery so that i can use device all day and avoid over-charge or possible battery damage?

Beautiful just Beautiful
Guys i have another one for all of you
"Is there a way that i can use my Phone without connection so that i will have no bill charges ?"

Batteries in Tornado can (even should) be charged often Don't worry about it

Yeah, over-charging is no problem. It'll stop charging when it's full.
This does raise an interesting question, one I haven't really bothered to try but have just now become curious about. Can you plug the phone into the wall, sans battery, and use the phone still? Or will it only function, plugged in or not, with the battery installed?

Phone turns off when you get battery out :/

LOL, I just tried that last night, and... ohh Noo it don't even turn the power light on w/o a battery... so @Amaric: Keep charging it!

I am aware that phone is not working if you take out the battery and connect it to a charger. I was wondering if there is some kind of a workaround.
My plan was to have phone switched on for months with wireles ON too. That just can't be good for battery and it could even be dangerous.

Do these tests, and post results
Turn off power savings on Wi-Fi and leave phone ON, doing something over the internet, just idling, so that the LCD is off. Say for example: acting as router.
Conditions:
1. Phone w/full battery -
2. Phone charging w/full battery -
How long did he battery last? How did the phone temperature change? What would you guess would happen in 48hrs of usage?
EDIT: My experience with Wi-Fi is that it drains more power than the charger output. Temperature raises substantianlly w/o LCD, gets extreamly hot w/LCD on. So what would be the options?

when im booting linux and the phone is charging you can take the battery out but the phone will still be on nice

Is this a joke? If not, then some change to a software (OS) could do the trick.

my opinion? If it does stay on after removing the battery, then it'll do the same if you have the phone on while running Windows, and charging and remove the battery. Battery charging is not handled by OS, its handled by Hardware.

Does anyone else think this is true? I think it would be unlikely that having the screen off but wifi on would use more power than the wall adapter provides.
I suspect that you could jumper the battery connections to mimic a full battery, but I am not going to try.

I think you can put resistors to mimic the internal resistance of a battery, but I wouldn't recommend it. If anything goes wrong you might burn out the charging/power control circuit which probably would turn your phone to a brick.
Oh, and the whether it charges when plugged in and using WiFi depends on your charger. I've got a 6V 2.4A (15W) charger for my phone, good luck using up all that juice with a Tornado. That thing easily charges my TyTN with HSDPA (3G), WiFi, Bluetooth and screen active.
15W is more or less what my laptop uses under normal load

UNI get trun OFF on 66% Battery

Hello,
anyone have solution for Uni Battery
My Uni is getting Turn off when battery power is 66%,
I tried the procedure defind in wiki page, but still same
Regards

Sorry man but no help for your battery
I have same problem and tray everything possible and impossible but nothing help
Best solution is to charging your battery in AC charger not on usb PC connector
cheers

My Dear, Thnx for replying,
I always use AC Charger, i use USB just for Sync nothing else

Or buy a new battery...

I had this problem, but my solution was a tad risky.
Try discharging the battery COMPLETELY, so letting the Universal die at 66%, then trying to turning it on after that until it simply will not turn on anymore. When you get to that stage, take your A/C charger and plug it into the Universal, allowing it to charge for 9-12hrs (overnight is good). Once it's fully charged (green light where the orange once was) take it off charge and see if that 66% goes any lower. Mine goes to about 12% before it dies now, which is a good day and a bit of charge for me on the stock battery. Not bad, considering I top it up everynight anyway.
The reason it is risky is because I've heard the batteries the Universal use don't like being completely discharged. Not sure on the technical reasons why, they just don't. So I'd consult another before trying this.

go universal's wiki and read the how to fix battery issues!
you may need to recallibrate your battery!
if you update your latest rom, with the battery not fully charged, you need to charge the battery to 100% and flash again you rom....

dont mess! for the cost, buy a new battery. Batteries do wear out. If it is a fake one, they wear out even quicker.
Had the same problem myself, tried loads of stuff. In the end I also bought a new battery.
One thing you could do, is run your uni with out your SD card.

Thanx to you all for replying,
I think new battery suggestion is good, instead of taking nay risk.

[Q] Does not recognize battery

Hello everybody!
I have a tranformer tf101 with + / - 6 months of use. After being stopped a few weeks (drained battery) it no longer charge and the system does not recognize the battery. When I plug the charger he starts the boot and not charge the battery. In settings with the battery status is "unknown" and a question mark on top.
I've given a factory reset and nothing. Has also has opened the tablet and unplugged and plugged the battery again. I did a test trying to turn on the device without battery and it turned on like before, like when connected (interrogation and status unknown).
The charger is apparently working, coz is charging dock.
I can not send to warranty because I live in Brazil...
Can anyone give me a light? Have researched a lot and found nothing ...
Thank you all!

Try plugging it into a USB port on your PC and leave it plugged in overnight, turned off.

thanks for the reply! I've done it, one entire day on energy and other day directly to the USB... But nothing!

Well... It might be possible that the battery is busted from being discharged for so long.
Although... Does it work on battery or does it instantly die when you unplug it?

When I disconnect die instantly! But if is on dock, he stay on

Yeah sounds like the battery is busted then. It works from the dock because the dock acts as a charger for the tablet, just like the 'real' charger.

Strange how a battery with six months of use given problem.
Would if I try to put a higher charge on it (20v) and force her to reactivate might work?

Batteries only last so long, and yours sounds like it is shot.
It's very strange that yours went bad after such a short amount of time.
If the charger charges the dock but not the Transformer, then it's not the charger.
You could possibly buy a replacement battery and perform the surgery yourself.
Other than that, RMAing is the only thing that can be done.

Software should not be the problem, right?
I'll try to overload the battery to see if she resurrects.
Then post the result!
thanks all for now!

It not that strange. Its not the age per se thats the issue here - its that it was discharged for so long. Once a battery reaches a certain level, it simply wont charge anymore.
Applying 20v will just blow the fuse in the TF, or worse - fry the whole thing... Dont do that
I read somewhere the fuse blows at 17v or something.
And even if we ignore the tablet for a second, applying higher voltage to the battery will just kill the few cells still alive.
And, in worst case, it can even cause the battery to explode, possibly starting a fire and/or damage a person. Although thats not likely with such a low over-volting as 20v. Im just trying to tell you not to put more voltage on a batter than its designed to get
The only way to 'possibly' repair a dead battery is to trickle-charge it, meaning applying a low voltage over a period of time.

Hello Goatshocker!
This charge 20V must be made directly to the battery and not in TF, it really would kill him! And it would be just a "scare" the battery in about 2 seconds only, the rest of the charge would be normally done after (15v). I've done this with cell phone battery several times!
As the battery is dead it seems, think it's the only option.
But before doing so I'll take you on an assistance to make sure it is the battery.

Ah yes, you are quite correct about that. I completely forgot about that method.
Yes, that might indeed work. But I would only do that as a last-resort, although you seem to be quite out of other alternatives

I took him in an assistance yesterday. Tomorrow should tell me the problem. Depending on the result already do the "scare" on battery.
then put the result here!

I had a similar problem. I tried connecting it to different sockets and it finaly charged.

whath kind of sockets you used?

Unfortunately, the overcharging did not work! The battery was completely dead, not sure how this is possible! But it's a valuable tip! The battery dock is the same tablet. So I changed them and I was working with the tablet and dock only works on energy.
Can anyone advise me a reliable site to purchase this battery? The model is ASUS C21-EP101

My HTC One X Is Dead??

Hi dudes I have a big problem with my htc one x, my cell phone doesn't charge anything (the red led dont turn on and the charge dock doesnt get heat) It didn't crashed or something, it was with low battery and I took borrowed his charge dock (I was in his house), but it didn't charge anything, as I said my cell phone wasn't crashed or hitted by nothing, It just stopped charging, what can I do to revive it? Please help mee :crying::crying:

Did u let it fully die? Sometimes power cycling is not a good idea...shooot.. Doing it isn't good period. Let it stay in charger overnite.. What ROM you running ?

Yes the charge fully died, and turned off, I let it in the power plugged last night the whole night charging and nothing happend, It was working well untill I pluged it with my friend's charger, his charger is 5v 800mA, since I plugged it on, it stopped charging, that might damage my phone? I mean all chargers are the same but , seriously that charger could kill my phone? is weird

Not all chargers are the same. Have you tried using your own charger?
Sent from my Evita

Yeah I tried with 2 diferent chargers but nothing happend, since I plugged in my friend's charger my cell phone doesnt want to charge anything :crying::crying:

What happens when you connect it to a PC? Do you get a connect/disconnect sound at all?
Sent from my Evita

Nothing happens, the red led is off always, dont even't flashes

How often did you power cycle (let it die completely) the device?
Sent from my Evita

ummm that's really weird when it happends, I'm always with my phone charged but yesterday I wasn't able to charge up and it ends with the battery charge

That doesn't really answer the question, how often did you let the phone die completely?
Sent from my Evita

maybe once every 3 weeks or 1 month

Ok. I'd keep trying to charge the phone, but unfortunately this kind of thing does happen with electronic devices from time to time. There's no real way to say exactly what's happened but it's very possible you have a brick.
Sent from my Evita

the last 2 weeks my cellphone was automically rebooting, the bottons of the cell phone (back,home,and the other) start flashing and automatically rebooting, I don't know If that says something what do you think?

Could he possibly hold down vol and power..for a long time...maybe it could get to boot loader,,,,?

I tried but still dead x_x

Power cycling shouldnt bother a mobile phone battery to be fair, unless it's left in a low state for an extended period of time (8% discharge per month roughly) so it's a bit of a misnomer. Lithium batteries should never be fully discharged but as a safeguard you will find when the battery reaches 0% as displayed on the phone the battery is still more than halfway charged to prevent this kind of thing happening. (Most phones register 0% at 3v but the safety threshold is around 2.2v, absolute battery death is 1.5v. Bare in mind at full capacity a cell is 4.2v so your pretty safe when it gets to 0%)
What is more likely an issue is using a faulty charger, there are dozens of cheap chargers which will trash a battery. It is disgusting what gets through the borders from places like China, these things don't have adequate power regulation or filtering. At best you reduce the phone lifespan, at worst it burns the house down. Never ever use a charger than costs less than $15 as there's a reason, decent components cost money unfortunately..
Now, if the device won't charge (a usb 3 port on a pc is ideal as it provides a stable 5v at 900mA or more if a genuine HTC charger isn't available) or switch on you can try removing the battery (be careful as the HTC screen is delicate and there are special tools you need), there are guides on the net or if your not confident then take it to a service centre and they should replace it for you for a fee.. if you buy a new battery off eBay then don't bother with the high capacity as they're fakes, if HTC could cram extra mA into the same size they would - but it's against the laws of physics to get double capacity.
I'm sorry your phone appears dead. I hope it's just the battery, just be very wary about unbranded docks/chargers as they're evil.

Check the Charging port and switch the cable
Maybe the charging port is broken.
On the other side maybe the cable is broken did you try charging another divice with it?
The solution may be simpler than you think.

Friends when I plug in my htc one x to my computer, my computer made a sound, but it didn't detected my cell phone (just made a sound when you plug-in any divice), and my cell phone doesn't charge is there any I can do? Or is dead

You might be able to get a jtag repair done.

Try Another Charger

you have to jump start your battery if you dont even get any feedback from EDL or fastboot. just plug in c type connector, then repeatedly plug in and out your charging adapter. this once brought back my old xperia xa ultra from being completely dead to back to life. also dont drain your battery past %15-20.

I'd like to know your findings from the service center or if you were able to revive your phone. Same thing happened to me. new phone arrived and the battery was drained. LED Lights flicker when plugged in but won't turn on.
the phone is expected to recharge even from a flat 0 battery.

Hi, of course the same thing happened to me. I didn't notice the battery and it ran out to zero. Then I can't charge the phone anymore. I tried different cables, different chargers and nothing. After connecting the charger, only the LED flashes and that's it. I left the phone on the charger for a few hours and something didn't change. Don't have new information on how you ended up in the service? thx

This thing worries me a lot!
Also because I have seen that it is a very common problem among Poco phones.
Even with a lot of attention it can happen, inadvertently ... at that point what do you do?
What if it happens out of warranty?
Is it possible that there is no solution?

Has anybody found a solution to this problem? Which I think is a software/coding problem.
I had the exact same issue in April (phone bought in January) where I didn't notice that the battery had gone flat and plugged the charger in and left it to charge, only it didn't.
Now I was in the position where my son also has the same phone so to diagnose the issue, i took mine apart and removed the charging port and swapped it with his. No change, his phone charged mine didn't.
I then swapped the batteries, his battery would charge in my phone and weirdly my battery would charge from '0' in his phone. So the charging ports and cables were now known to be fine and working, but also the batteries were both able to be charged so it seems it is a software issue.
I now have a new battery on order because he's not got his phone any more
