Power problems-dead battery

[tedd]

Hi ,well I ve bought a 9 month old sx56;I charge it for a few hours ,and when I reconnect the phone fm the crandle,after 20 seconds switches off.I try to switch it on but doesn't respond to the button ,soft reset nor hard reset.What should I do?Now f.e. the sx56 switches on only when you install it to the crandle ,when I reconnect lasts on for a few secs.

Thanks guys.

Thank you


Take care.

But I'm thinking that ,even if the battery is dead it will notify me or at least swich on for a m.second .Dunno what to say.

[tedd]

Hello ,
The battery indicates 100% but the device switches off.Even if I uninstall it from the crandle it lasts a few secs ,but when I push the on/off button doesn't switch on again.

I too have exactly the same problem. Let me know if the new battery fixes it.

Hope it works out

Thanks

[tedd]

Ok,will let you know ,and where to buy the battery ;if that fixs the problem.By the way ,is your xda a 2nd hand too?The battery costs $80 +$24 for shipping.

Cheers

Yes i brought it off ebay! Not sure what the problem is!

If you can post what fixes yours that would be appreciated :D

Thanks tedd, good luck!

-With the new battery used to work perfect for many hours but the same day died(after I left it charging for a few hrs).
- When I first installed it , the on/off button didn't respond so I had to switch on by plug it instantly to the crandle.
I first unlocked it by using the rom kichen from Yorch.net. maybe it's a software or hardware matter,who knows...

THANKS!!!!

I actually desoldered the SIM door switch and bridged a wire across the terminals! The switch was broken you see! The XDA now thinks the door is always closed 8)

Still wouldn't work properly though so I'm going to order one from the same place as you. Hopefully it will then work!

Thanks for your help :D

[tedd]

Everything seems ok .For instance,went out and was working perfect for many hours.
When I got home charged it for a three hours.Then before I go to sleep uninstalled it fm the crandle and opened the reader to read a book,and guess what :switched off by itself!.

Tedd: I just sent you the email with the pic in.

For everyone else this is what is did to stop my XDA from resetting all the time!

1) Desoldered the sim door switch and binned it because it was broken!

2) Used one strand of copper wire and bridged over both terminals to trick the XDA in thinking that the door is closed!

3) Remember to tin the wire first as the terminals are very small!

4) FINALLY! Don't take the sim card out when the XDA is switched on!


My XDA still won't hold charge though! Must get a new battery and hope nothing else is faulty!

Here is the pic!

[tedd]

Thank you,Mark for the email. I 've tried everything.

I bought a new 1800 mAh battery but the problem insists.Don't buy another battery yet.

Guys I think that is not up to our hands anymore,we must send it for a repair.I have to ship it to TX .Will post you back again when the diagnosis comes up. Will take some time.

But I insist that the 2 day new battery,I bought, DID NOT solve the problem.Think about it ,which battery does not last even to switch the ppc on for at least 1/4 of sec?


Regards,

Tedd

My battery lasts a few seconds!!!! Had all the same problems as you!

It works fine when the XDA is connected to external power, but when it is removed it dies!

It also used to reset alot, even with external power! The switch fix has solved that now though.

My power feed to the XDA is from a PC via a BRANDO USB cable. I measured the output from it the other day and it is kicking out 350mA. I don't know if this is even enough to charge the XDA battery!

Someone said between 500mA and 1A is needed to charge the XDA, so this might also be the problem.

[tongben]

I get the same problem with dead battery. If it has a power source, it works nicely. If unpluged from power source, it dies after 20 seconds. I use the original T-Mobile power adapter 1A and it does not charge the battery. I also use another adapter 600mA and does not charge battery neither.

I would love to know how to fix this problem.

My problem started when I upgraded the RS from Tmobile from 6.24.0 to 6.24.1 . The upgrade failed at 1% and then the battery drained and never recharged. I have not try to solder or replace the battery yet.

There have been many posts now with this problem and one thing has become apparent - no-one knows what causes this fault.

After alot of thought i now believe that either upgrading the rsu/ruu or unlocking the xda may cause it not to charge. Many people have reported that failed installations which hang on 1% result in the battery never charging up.

One thing that wories me is that i perfomed an upgrade to 4.21 and that failed at 1%. Thing is though my phone actually still works and recognises it is running the 4.21 version, strange! It still does not charge though - it only runs on power from the USB sync cable.

When i brought my phone off ebay the power button didn't work or the battery wouldn't charge so i couldn't test my theory out :(

If anyone knows what is going on here i would be glad to here your views cos this problem has got me stumped for sure!

Hello guys. The fault is very expensive to fix it.At least on mine unit.
The special technicians couldn't fix the unit.
They said that I have to replace the whole motherboard for $200.That what the diagnosis showed,a faulse motherboard omg!And they tried many different sources and batteries to charge it.
The phone is useless now.Donno maybe I will pay for it.Maybe not,sell it as it is or for spear parts.

I think one final solution to go for an SD card copy of the ROM and GSM through the bootloader from a new working XDA1 then flash it into your non working XDA
otherwise as mentioned in another thread telling that the service for the device informed the user that there is a damaged motherboard due to radioStak failure, so he had to purchase a new motherboard for about 300$ as I remember.

Peace

Good idea!

Has anyone got or know where to find a copy of a working ROM and GSM that i can try on my xda.

Currently running

3.17 ruu and 4.21 rsu

Failing that i am going to link the xda up to some high power AA batteries and fool it into thinking that the battery is full. This should allow me to install a new rsu.

I still believe that the non charging fault is software related as i have tried everything! I even bridged a wire across the fuse F0 like aquasesh did! Still not charging though.

If none of these work my xda will surely be dead forever :cry:

[lbazil]

That won't work either. I've tried to fully charge an external battery on a different XDA, then connect it to the one with failed RSU upgrade, and it still didn't work (failed at 1%). Some RSU corruptions are just not possible to fix without a serial cable and ceratin software. A user from Russia has observed technicians in a service center fixing failed RSU upgrades using some terminal emulation software, but could not get them to share a copy.

This is definatly a software problem. My Xda was working perfectly when tried to remove the sim lock with Specail ROm and there onwards the battery is not holding the charge, Reinstalled the GSM and Orignal ROM.. nothing works..
Any Ideas

[PHB]

I'm getting exactly the same issue on a completely stock, never-been-modded in any way XDA.

I had identified that the unit would start ok when on external power if the battery [well, the rear of the unit] were removed if I depressed the switch near the sim card slot.

In my case it may be a totally dead battery; this XDA was given to me by a work mate who has hated it since about 3 months after he got [the same time I got my original one - about 14 months ago] and has used it intermittently ever since. I don't know how long it is since it was charged but with Li-On batteries, once flat [truely flat] always flat... so I've read via Google; might well be misinformed.

Anyway, getting to the useful bit of info, I noticed that someone in a previous posting has removed the switch and soldered a fine wire across the points. To me, someone more comfortable with an axe than a soldering iron, this seems overkill...

So, instead, I removed the actuator arm from the back casing; a small flat bladed screwdriver will pop it off in seconds. I've then used electrical tape to force the switch into permanently closed position. If this stretches over time [which I doubt] I'll simply put a wedge of paper in there; now that the arm is removed there's nothing to foul it if I do.


Phone has booted and is now [I hope anyway] charging up the battery]

Hope this is of use to someone,

Cheers,
PHB.
