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
Hi all.
I've over-discharged my stock battery and now it doesn't charge. It lights up green as soon as I plug the charger. I've tried different chargers but didn't help.
I've made this using short circuit so don't think it's related to Sensation. You may ask why I tought over-discharging may solve the touchscreen issues. Don't know if it's solved because phone doesn't open.
Do you have any advice to restore the battery rather that getting a new battery? I've already ordered new battery though.
Certain laptop battery manufacturers use a circuit which stores battery charge information, but is itself, "kept alive" by the residual current in (even a dead) battery.
I've seen the case on a number of times that discharging below the "allowed" level causes this circuit to fail, thus the communication between battery and device is incorrect, inaccurate or, at worst, not there at all.
(this is why there are more than just + - on your battery)
You could find the correct recharge rate for the battery - current and voltage - and charge it manually, and hope that said 'battery state circuit' comes back to life, but honestly, I think you'll be, as they say, SOL.
I've had perfectly good laptop batteries, holding a full charge, having a great discharge rate, but the laptop would refuse to accept it, just because of this little circuit.
WARNING: Charging / over charging / charging in a way other than in accordance with the original device literature can VERY likely cause the battery to fail completely, including, but not limited to FIRE or EXPLOSION! DO NOT PROCEED UNLESS YOU KNOW EXACTLY WHAT YOU ARE DOING. LiPo (and LiIon for that matter) are EXTREMELY DANGEROUS when used wrongly!
All the above said, have fun, don't blow yourself up, and let us know how you get on. Also, from a personal point of view, I'd be interested to know the 'technical reasons' behind the thought that over-discharging could solve the touch-screen problem - can you remember where you got the info originally?

wtf? did you shortcut the battery or the phone? if shortcut the battery it my be blown. Anywyas you could try jump charging it, unplug and plug it in fast, or put it in a outlet which has a switch and try toggling it on and off for some minutes, you may be able to jump it up to the voltage it needs to start charge

This is my second unit and it has touchscreen problems too. I'm not an expert but here is why I did that.
My phone was working normally and had %20 battery left. I went outside and didn't have extra battery or charger so I've used my friend's USB cable and lapto to charge it. After it reached to 44% I unplugged it and saw touchscreen issues started. I've searched and remembered some advices from XDA like discharging and charging may solve it so I gave it a try but it didn't help. Then tried over-discharging and charging but stock here.
What do you mean by charge it manually?

I did short circuit the battery I know sounds crazy but I'm sick of touchscreen issues. Are you saying that I may try connecting it an appropriate charger's output directly like + > + , - > - ?
I'm saying, chances are, it's wrecked. You shouldn't really discharge batteries by short-circuit - that puts massive stresses on the structure of the cells in the battery and probably completely ruins it.
It can also cause excessive heat, which can lead to nasty things happening.
Recharging the battery by connecting + to + and - to - is theoretically possible, however, to do this SAFELY, you would need to know the manufacturer's recommended charge rate, times, voltages etc. They differ greatly.
Do it too slowly, and you just result in a very inefficient trickle-charge, which can sometimes do more harm than good....
Do it too fast - cells in the battery become gaseous, the gas vents, and you have fiery explosions... also not good.
Seriously - I would strongly recommend against playing with it. If you want to see what CAN happen when it goes wrong, YouTube it!!

Yesterday I connected the battery which is stock 3.7 V to the my digital camera's charger which is 4.25 V, 0.25 A, 50-60 Hz with cables for 6 hours but didn't work. BTW, stock charger is 5V, 1 A and 50-60 Hz.
Can I try jump charge with this camera's charger? If I can, how fast should I connect and disconnect the cable?
That's exactly what I'm talking about.
It should be noted that the Sensation stock battery is LiIon, rather than LiPo, but the effects can be very similar, and just as disasterous if that happens when your battery is in the vicinity of.... anything!!!
I think it's dead mate =/ but just switch it on and off a couple of times in a second

Hi
I have Samsung Galaxy S Plus and I'm looking for the following information:
1. Does the phone drain power from batter when it is charging it?
2. Does the phone drain power from the batter AFTER it's 100% charged, and is still connected to the charger/USB?
cheers
Lucas
1. yes, you can drain your battery while it is charging if the charger is weak and your phone is under heavy usage
2. yes, because to improve battery life, the charger will let the battery go from 100 to 9X something, then begin charging again. (Same for laptops)
Hi Dark3n and thanks for your response.

?? Are you positive about this?
I mean, improving the battery life is charging it to 100%, and then not draining power from it, if it has an option to drain power from outside source.
ps. I have Dell Inspiron 6400, and it does not drain power from battery when fully charged and still connected to the AC outlet.
cheers

A good charger will offer something about 500mA+ of current, a weak one less.
If the current of the charger is not higher than what the phone currently drains, the battery will not becharged.

I'm not 100% sure, but fairly sure.
Also improving battery life would be to never charge till 100%.

I see. But if that was the case wouldn't Samsung doing the worst thing possible to the battery inside it's own phones?
Try to follow the logic(if the phone was constantly draining the power from the battery):
The phone is charging. It reaches 100% (so according to your article it's not good), then once it reaches, it can't go beyond that, but since the phone is taking power from the battery, the batter instantly goes below 100%, but then the charger tries to charge it back to 100%. So it's not only charging it to 100%, but it's doing it CONSTANTLY as long as the charger is connected to the phone.
If either of those information was true, Samsung would just conciously damage it's own product.
...
I contacted the Samsung Live Chat just now, and samsung employee told me this:
"P.: The phone takes power from the charger/USB when charging."
"P.: Yes, I am sure. All the phones takes power from charger/USB while charging."
"P.: Yes, you are right. The phone does not drain power if it is still connected to charger."
Any answer to that guys?
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?

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.

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.

when you run the battery down to 0, there is always the risk that it will not charge again. batteries have a safety in them, if the charge gets too low, the safety trips, and the battery will not charge again.
unfortunately, you will likely have to buy a new battery.

there is one way i have heard about, but never tried it.
basically, you need to remove the battery from the phone, then cut the end off a usb cable and expose the 2 charging wires, then touch the power wires to the proper terminals on the battery.
important note, you only want to do this for a couple minutes at a time, then let it rest for a couple minutes. prolonged charging like this could cause the battery to explode, because you dont have the safety regulation thats built into the phone.
you should only have to do this for a couple times, then the battery should be past the low safety level and will charge properly in the phone.
if you want to try it, search youtube for help, i have sen some videos on there about it before.
