I woke up to find my SDA powered off and unable to power on, which was odd considering it was plugged in to a (Motorola) charger.
Since the orange charge light doesn't come on at all, I suspect it's just a dead battery. I've touched the battery contacts to a battery tester with no response - as if the battery is totally dead, which is promising. However, I can't be sure I'm doing it correctly since I've never tried this on a battery I know is working.
There are 4 contacts on the battery, and I'm wondering if there's more to it - like needing to have 2 contacts touching the positive lead and the other 2 touching the negative lead.
Can someone try testing their battery and see which contacts give a live (charged) result?
Thanks

Normally you shouldn't try to use chargers not designed for your phone. What has probably happened is that there wasn't enough current output in the charger, and it completely drained your battery. Your battery is probably fine. Get a proper SDA charger and try charging it again. You can even take it to a store and ask them to plug it in for 15 minutes while you browse the new phones.
Yeah - I lost the original charger, but I've been charging with this Motorola one (output 5V / 550 mAh) and via USB for the past 6 months without problem. I still think it may be the battery because it was at 50% when I went to sleep.
What are the output specs of the original charger?

The stock HTC charger (model ADP-5FH K) has output of 1A at 5V. But if you had no trouble charging before it shouldn't be a issue, unless the charger/battery is faulty.
If you have a multimeter you can verify this. To check if your battery is charged place contacts in (+) and (-) contacts on your battery and it should show ~3.7V. I just tried this.

Thanks, silencer. I don't have a multi-meter, but I was using the battery tester as a way to gauge whether it was putting out any current at all, and it sounds like it's not. You were testing the 1st and 4th contacts?
I have read elsewhere that if your battery goes below 10-20% you won't be able to charge it with anything but the stock charger, so I think that's the problem, but I'll probably order a new battery as well just in case.
Yes I check the voltage between first and forth contact. What sort of battery tester are you using? Is there a digital read out display?
You can also try a USB to mini-usb cable to see if the battery get charged. From what I can remember USB ports are designed to give 500mA at 5V, but I have charged my phone when it was flat using a USB cable.
To follow-up in case anyone has this problem in the future: I ordered a new original charger (ADP-5FH) off eBay and with it, the phone's orange charge light came on right away and after giving it a full charge my phone is back up and running.
I'm inclined to think that it's not the difference in mAh of the original charger (1000mAh) vs USB charging (500mAh), but that there is something unique to the original charger which can "turn on" the charging when the battery is completely dead - perhaps something communicated by one of the extra pins in the mini-USB connection.

got an SDA with no prior knowledge of its history other than "it wouldn't power on" well when I got it the battery was completely dead "0 volts". Since I didn't have an external charger I did a little work to my external MPx220 charger "uses a 3.6v LiIbattery" to fully charge the SDA battery. I put it in and tried the key sequence to get the bootloader to appear.. no go. Tried camera button while I plugged in USB with and without battery.. nothing. So I left it plugged in while I was searching the forums last night for more information the screen turned white and all the keys lit for about a minute then it turned off again.. and I haven't been able to get it to repeat this since.. is there any hope at this point? Thanks!
now I'm confused.. I've seen yet another method for entering bootloader on the Tornado's http://wiki.xda-developers.com/index.php?pagename=HTC_Tornado the camera + botton on opposite side and power.. this doesn't seem to work for me either.. but which one is right? does the battery need to be in or out? usb plugged or unplugged.. I can't believe this device would be so "dead" as to not do anything at all.. will T-Mobile honor the year warranty of these new phones?
Is this model just so new that not much is known about it? I'm surprised that I haven't gotten any type of input yet.
the same problem

i have the same problem, please if you have found the solution, tell me or send me an E-mail [email protected]
To me it seems like the battery is not charging at all. I've seen this with Motorola Li-Ion batteries. Unless there is enough amperage in the charger, the battery won't charge, regardless of what it looks like. If you really want to go forward with this, one idea may be to get an actual SDA charger, or replacement battery.

Or maybe a Motorola charger? USB cable is 5v, Motorola charger w/USB connector is 5.9v. Motorola phones can charge from PC USB port/hub, but only if the phone is turned on. If phone cannot be turned on because the battery is dead, you need the wall charger...
help people....
dropped my SP5m two weeks back and ever since it is not powering ON
ne idea what I could do to check what is wrong?
tried switching on the phone minus the battery, but it does not switch on (correct me if this normal)
I even tried get the voltage checked of the battery, but it also shows zero, maybe there is no left in it.
Checking voltage on the phone four pins in the back also shows no signs of any volatage, even when charger adaptor is connected. (I use Moto razor charger)
any help/idea is welcome....

Have you tried powering up with USB plugged to a PC? Also, try powering up in BootLoader, sort of to make sure the motherboard is responding. Can you get a loaner battery from a friend? Your battery might have just broken internally(seen that happen on other devices).
I don't think it would be a hardware failure though. Trust me, If you only saw what I did to my SDAII, literally squezzed it between the 5th door and frame of my Van. Broke screen lens and LCD, warped housing, broke D-Pad(joystick) and, i pulled out battery, placed battery back, turned on phone, and re-dialed using bluetooth and it was working fine
For one thing, don't use any other charger except the one for the SP5m!! There are several posts in this forum that refer to problems using other chargers. If the battery is more than 50% charged, then your charger might work. Otherwise there isn't enough current output in the Motorola charger to kick-start a dead battery. So test with an OEM charger!!

Really? My experience is that Motorola chargers will charge HTC devices but that HTC chargers will not charge Motorola devices so I always assumed the Motorola devices drew more power.
Motorola charger have approx. 0,5A when HTC chargers got 1A.
Hi everyone,
My first post as I haven't been able to find an answer. My Photon Q was probably about 30% charge when I last checked with it on. An hour or 2 later it was a little warm and was off. So I went to charge it using the car charger with 500mah charge rate. I came back about an hour later and the phone was really hot and no charging screen so I unplugged it. The green led light is lit when the phone is plugged in.
I tried holding the power button and volume down button, but it won't boot. If I have the usb charging cable plugged in from a PC or charger adapter when pressing those buttons, the green light will flicker off for a fraction of a second.
I then proceeded to dismantling the phone as I suspect a battery issue and the one in this phone is stupidly non-removable. After taking the back cover off, I tested the battery posts and received 0 volts. I still don't know if the battery caused the drain or if there's a short in the phone. I then took off the inside cover that holds the battery in. A few T5 screws later and the battery was removed. I connected the battery to some AA batteries in series to see if I could get a charge. A few hours later I got it up to 3 volts which held for several hours. So I connected it to a few more AA batteries in series to try and raise the voltage. I got it up to 3.67 volts and the battery is listed at 3.7 volts.
A day later and the voltage is still at 3.67 volts so I put the battery in the phone. I went to try and power it on, but nothing. I then connected it to a usb cord and received the slow flashing red led light a couple times before switching to green. The battery started getting warm again connected to the usb charger. After 20 minutes it was approaching hot so I unplugged the USB. The battery read 3.54 volts. 30 minutes later, 0 volts again.
Does anyone know what the actual voltage range is for this phone, as my old Samsung M320 is also 3.7 volts, but when testing the battery I get 4.10 volts? I heard it's pretty specific on minimum voltage. Any ideas for a temporary battery or way to boot the phone before spending $50 on a replacement battery and then find out there's a short in the phone. Is there another key combination to boot the phone, I'm trying to boot it to at least get my pictures and other data off it.
Thanks a lot in advance
Matt
Not the battery, seems to be an electrical short but where
I bought a new battery for the phone which had a 0 volt charge when I received it. I tried putting it in the phone as is to use the phone charger to charge it, but got nothing. So I charged it using 2, then 3 and then 4 AA batteries in series to get it up to 3.7 volts. I then put the battery in the phone and noticed the 2 large chips and the chip centered above them located by the camera get a little hot. I tried with the charger connected and not connected, but same thing. Power button doesn't turn the phone on. Just the green led lit when the USB power cable is attached. So now it seems there must be a short in the phone. Anyone know where I can look to check for a short, blown resistor or something in this phone? Or at least where the rom chip is located so maybe I can turn it into a usb drive to get my data at the least.
Anyone? I still haven't been able to find a solution. I don't see pins touching, but if some pins are touching in the usb port, would that cause the heat issues when I put a battery in that I charged externally? I do get the green led light when I plug the phone in to charge so figure that means the usb is ok?

did you try a other charger ? do you have oryginal photon charger ? for me its not a reason of battery
regards
(in situation like that charging with normal usb cable when you plug phone to pc dont charging battery, you need motorola usb service cable to make it work)

Yep used the motorola cable that came with the phone (plugged in the wall and just the cable in multiple computers, another motorola house charger (the same as the one that came with the phone), a motorola car charger, and a samsung house charger.
When you say motorola usb service cable, I assume you're not talking about the motorola cable that comes with the phone? What usb service cable are you referring to?

factory / sevice cable ( i make my own from below tutorial)
http://forum.xda-developers.com/showthread.php?t=1077414
if you buy / make this cable , you will be have posibility to use RDS lite and flesh firmware this also make help (if you have low battery flesh with normal usb cable is not possible )
and second thing... maybe try some car charger ?
I have had my Verizon Galaxy S4 since February of this year. I've been using the stock Samsung AC charger that came with it. It's always charged the phone pretty fast if I wasn't using the phone. It would charge about 15% in 20 minutes. Now it's only charging about 3 or 4% in 20 or 30 minutes. Now I didn't do anything different to my phone. I've been on this same ROM for over a month and this is just now a problem in the last week. My wife has the exact phone and charger that I have and when I use her charger it charges just as rapidly as mine used to, so I know it's not the usb port on my phone itself. I haven't dropped or damaged my charger at all in any way either.
Does anyone have any ideas about why this is happening?
If it charges fast on you wife's charger you've pretty much answered your own question.
Try using her cable with your charger, if it still charges slow then get a new charger.

Ok, I'll give that a shot. Thanks.
I had the same problem too ! Did a full battery reset and everything is going good now !
You have to charge it for 12 hours and drain your battery until your phone don't boot. Charge it and here you are !
Yeah these devices act funky every blue moon. My wifes didn't even recognize ANY oem charger for a week. Only detected others as USB devices causing slow charge rate. Removing dust, component cleaner, fresh install, all did no good. Eventually it just resolved the issue itself. All chargers work normally again.
change the usb cables
I also had the same problem before. I'd been using the original charger and usb cable and noticed that charging takes a lot of time than normal.
I found that it's on the usb cable. I accidentally found it when I used gsam battery monitor. It displays the current being received by your phone when charging. Using the original usb cable, it only gets around 600mah. I tried another usb cable (from a previous Samsung device) and now my phone gets 1,900mah (closed to the charger output of 2,000 mah).
Every since I changed the usb cable, my charging is fast now. Hope this helps.
I would try a new cable and Charger that is rated 2.1 amps or better if will be charged real quick

I noticed that using the Pure Nexus rom my charging time became significantly faster. In fact I can get a full charge from nearly dead in just over an hour. This is using the charger and cable that came with the phone.

How do you make full battery reset?
The charging rate is based on the output rating of the charger, which is determined by the resistance value between the Data+ and Data- USB pins. If you use a cheap cable with high(er) internal cabling resistance, that will throw off the detected charger output capacity rating, and knock you down to a lower charging current and longer charging time.
Also, one time, even with the original charger and original cable, I couldn't charge at anything more than the default USB 500mA. I ended up having to power off the phone, and power it on again, which fixed the charging current and speed problem.
Install this app & check if it is getting charged at max current; anything less than 1200 mA when screen on & 1900 mA when screen off, you need to change your cable or charger

I read somewhere that if you activate airplane mode the battery is charging faster.
My nexus 5 went to 0% battery one night and died. I tried charging it with 4 different chargers, some with usb some outlet and a wireless charger to no avail. I then purchased 2 new batteries and the phone was able to turn on with the replacement ones. However they would not charge. On the battery status screen it would go from saying Charging (on AC or USB depending on how i was trying to charge it) for 5~ seconds to saying Not Charging. The charging icon was still on the little toolbar battery icon but it would not charge. So those two new batteries are dead :good:. So I thought maybe software issue, I had enough juice to get in the bootloader and flash back to 4.4.4 which would still not allow it to charge. Then I started flashing to other versions and eventually back to 5.1.1 to no avail. I replaced the charging port with one from my brothers nexus 5 and it still would not work. My battery and charging port worked in his phone however.
Now I don't know what to do! This is the first phone I've really had to research about bootloaders and roms and stuff so I'm fresh.
TL;DR: Phone goes from charging for 5 sec to not charge with different software versions (4.4.4, 5.1.1 +more), with many different chargers (including one that came with phone), with new battery and new charging port.
Thanks.
Mine did that with a new battery also. The new battery was a dud--I contacted the seller, who sent me another battery, and that one does charge.

I've tried 3 different batteries including my brothers nexus 5 battery which charges in his phone so I am confident its not a battery issue now.

if the actual USB port is working on ur brother's and so is the battery, i am afraid then u have a bad Motherboard...
theres a Texas Instruments BQ24192 I2C controller chip, that is what regulates charging, such as voltage, etc...
if it doesnt even respond to wireless charging, that may be bad https://www.ifixit.com/Teardown/Nexus+5+Teardown/19016#s53734
that would be my guess....
Well technically it responds to it but it only lasts for a few seconds. Wireless charging and wired charging get a response from the phone by changing it to say charging on ac or usb or whatever but it just goes back to saying not charging after ~5 seconds. Is this still a bad mother board you think? Is it worth it to try and purchase a motherboard or just get a new phone?
Any solution for this? Came later but did come to this problem.
