SDA won't power on: How to determine a working battery

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.

dead SP5m, not charging either

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.

[Q] D2G "Dead". Help reviving?

I used to have a D2G before I upgraded. Well I gave it to my sister and she happily used it for about 2 months. Then, about a week ago it just "died". Its pretty much a paperweight. The way it was explained to me the battery died and it won't hold a charge. I can't boot it at all because it won't take a charge from any cable and the OEM wall charger we had was damaged. The charge light blinks when its plugged in.
The device was rooted and running CM7. Was only about 11 months old and bought through Wirefly with no insurance so any hope of replacement is out. Any opinions on if it can be revived? Not will to insvest in a new charger/battery/battery only charger if she's dead.

did you pull the battery and check battery connections
you can buy a new battery cheap
or charger
phone may just need a charged battery and do a SBF
http://droid.koumakan.jp/wiki/SBF
but will not charge until a SBF is done
http://forum.xda-developers.com/showthread.php?t=1437177

I haven't checked the connections yet. Did do a pull for 10 minutes just for good measure. Also I intend to SBF it if I can boot it but that hasn't succeeded yet. Just not really too keen on spending yet. Really tight budget.

it is possible that battery just got too low for usb charging
and a wall charger will work

I'm hoping so. The problem is the OEM charger is damaged and won't charge it. I'm hoping to borrow one from a floormate if they have one and see if it'll work.

If battery was drained down completely, you won't be able to kick off charging using low current source (USB port), you need wall charger rated at least 850mA. The more, the better. Pretty much any smart phone nowadays uses such chargers, so I am sure you won't have trouble finding one among your friends. Tablets are often 1.5-2A which is even better.
When you plug it in, it may take like 30+ minutes before phone comes to life. Charging indication will start displaying only after battery is "off the bottom"
I recommend you to try to recharge the battery before you go any further.

My Stratosphere has a 1A wall adapter. I'm trying that. I'mma also try my friends to see what'll work.

Like everyone else is saying, wall charge the battery. Try putting it in someone elses phone and charging it as well if the first idea doesn't work.
There's a chance (though I haven't seen this happen out of the blue) that the OS was erased. Without an os the phone won't charge the battery. SO either charge your battery in someone elses phone or use someone elses battery to SBF your phone.

Nexus S I9023T doesn't charge

To whom it might concern,
I have been struggling here in Egypt to fix my Nexus S phone, I purchased the phone from T-Mobile USA and It’s not anymore under warranty. I sent my phone to a couple different Samsung service providers here in Egypt, but the problem is that the Nexus S not a popular phone in the Egyptian Market and they couldn’t fix it for me.
The problem started when I first left my phone over the night charging and I went to sleep. I woke up in the morning and the phone is only at %30, I can’t charge the phone whether by using a USB or wall adapter. My phone is currently dead and one last thing to be mentioned is that when I connect the charger I only can see the power bolt symbol but if I go to the settings of the battery it does show “Discharging”.
Thanks in advance, any help will be very much appreciated.

Well I'm no expert but I had the same problem but with my battery for my laptop. Even plugged in it said Discharging so it might be the battery. Sounds plausible since you see the bolt or it could be something with the hardware with a bad connection between the battery pins and the NS pins on the phone.
But as I said I'm no expert.

Maybe it's the usb charger port of the phone, having the same issue here! Though not as extreme as you, I ordered a new charger port but I have yet to put it in, think I will bring it to an expert in soldering. Also, you can buy a battery charger on ebay so you can at least charge your battery.

I also would like to mention something extra, I did buy a new battery like a week ago. I install the battery, the phone finally turns on, battery shows around %60 i try again to connect different chargers or even my usb cable and again the battery status is "Discharging" and i see the bolt symbol. I try to turn off the phone and take out the battery and turn it on back, again the battery drained so fast to around %50.
how possible can i check if its a faulty usb port?? and where can i find it online since this phone is not in the egyptian market!!!

Well I don't think it's the battery, sometimes when you pull the battery and turn it back on there will be a jump, don't know what causes this, not an expert. You can check wether it's a faulty usb port by trying different/new cables. If you wiggle the cable around a bit do you see any change in status? If it's not the cables, did you do anything software related? I've found that coming from ICS rom to jelly bean it got a bit more responive to my cables (maybe plasebo).

xperia XZ charging problem

Hi, I am a novice in phone repairs though I have successfuly replaced the screen and charging ports on a samsung s6 and note 4.
I am requiring some expert advice on this problem, I was given an XZ from my friend with a cracked screen and charging problem, the charging port became temperamental and failing (at least I think it was that) and eventually wouldn't charge at all. The charging port was handled a bit harshly toward the end, for example the charging cable lifted up and down to try to get a charging response.
Anyway I ordered a screen/digitizer and charging port flex for it, and fitted them, following a guide. Before this, the phone had around 2% charge. After the repair, I switched it back on and conncted the charger, the screen was fine, however there was no response from the charger. The phone then ran flat and eventually ran flat enough to not be able to show the "low charge" symbol when the phone is off. Then after plugging and unplugging the cable (via USB in the pc) it would charge for what seemed a second then stop, the red charging notification light was lighting up. The same happened with a wall charger. I then stripped it back down and back together again. This time there was no response if I remember right, then I connected it to the wall charger and left it for 3 hours or so. I went back to it and it had charged up to 15%.
Now i'm at the point where the phone is working, it's on 90% now, but it charges very slowly, around 60-350 mA per hour on Ampere app. So a full charge is around 12+ hours. This is in the wall socket with a fast charger. Additionally, it takes 10 seconds for the phone to recognise the charger after is is plugged in and that is consistent each time I plug it in. The phone now isn't recognised by my PC via USB, and also won't charge that way also, it just doesn't do anything if I plug it in there. Other than that, the phone works and it holds its charge well.
Any ideas? Thank you.

pick up an original sony charging cable - no idea why it makes such a difference, but.........

Hi, thanks for the reply, I bought a sony charger but it's still the same, drawing about 50-300 milliamps from wall charger, not recognised by PC and takes 10 secs exactly for the phone to recognise it's being charged. It's just odd how it stopped charging before the "fix", now the new flex lets it charge slowly. Can a battery problem cause this? It still holds its charge well. Maybe this problem is recognisable by some phone repair experts around here? any ideas?
Thanks

Noticed the phone only draws charge from a 3amp charger, anything less isn't recognized. And the power drawn from a 3amp can be 30-1000ma but averages around 300 ma. Can anybody point me to a hardware forum maybe? I can't find any, i guess it need taking to a phone expert but it's gonna end up costing more than its worth with the stuff i have done already.

Aukey Quickcharge 3.0 is working fine. It is cheap too.

I have just purchased a aukey charger, but my XZ seems to be taking longer to charge than the UH20 charger that came with my XZ. Any suggestions guys?

Have you tried cleaning/replacing the charging port itself? As i see, you replaced only the flex cable.
There's probably extremely weak contact somewhere in the charging hardware i think, because you need 3.0 A charger to get any kind of charging response. Weaker current probably gets lost at that 'weak contact'.
Buying new chargers won't fix that if you ask me

I have exactly same problem with you
I am about to buy a new charger, yet I saw your post
At first I thought it was the cable. Then my cable work normal with other phone. So does my charger, it connect perfectly with other phone (xperia xz premium and xiaomi mi5)
It seems that our phoneis the only one who can'y charge normally.
I am quite depressed, also looking for solution. Mind if you share if you have succedeed? Thanks before

Try plug in and plug out. My phone sometimes charge a normaxl. But need a lot of effort

Solved
Use the the detect usb in the notification keys before connecting the charger,, this will solve the fast recharging issues

Did you solved problem? I have same issue. Changed battery, usb-flex, no luck

Hi,
I have bought an used XZ.
The owner sold me this phone because he need new battery. I have replaced the old one after a week of test. The old battery works only for 6/10h and drain totally during night even if the phone is turned off. The new one have the same problem. I try to solve with an other battery, and nothing same problem. 12h of standby, after is totally drained. The strange thing is that I have the same battery life even when the phone is turned off, but not only this. If the phone is in 0% he charge without problem. If we have any % of battery I need to connect and disconnect the charger from a wall plug many and many times before he start charging. Phone give me the charge icon for a second and after nothing until I disconnect the charger from a wall plug(I have tested different charger and cable). During my investigation I have found that this phone results every time a little bit hot even if turned off. I have try to disconnect all is possibile, but the heat is from CPU! Now I know that this is the cause of fast discharging in all conditions.
Now I need to know if anyone with a "normal" unit feel the phone heat while turned off and while is on wich temperature have. Mine is every time on 34/35° in standby. Let me know,
thanks

i have same problem . sony xperia xz and sony corp is very very Rubbish

Hi Guys,
I found a way to charge my Xperia XZ with the same loop problem.
Try to push upper volume pad together with power button and plug in the charging cable.
Hold the buttons for 3-5 minutes - you will feel vibrating signals like 3 short and 1 long.
so hold it and then simply leave it for a several minutes and it should start to accept the charge.
Alex Kutikhin

Yes - I had this problem...fixed it by holding in POWER UP and OFF button for 120 seconds.
Do not let go...you will feel vibration (1 short, 3 short). Keep holding for 120 seconds.
Device should now be powered down. Plug in charger cable and leave device off until 100% charged.

Still no fix for the original post’s problem? Having the exact issue with my xzs right now.

Thanks for the hint...
Old Thread, I know, but I encountered this issue today on an Sony X compact - F5321. Fixed it and want to report back for the next guy.
Same symptoms, noticed first a slow charge, phone was drawing low current and only responding to cable after 10 seconds of plugging in. I than checked for data connection, couldn’t get any. Opened it changed the USB port - BINGO - that fixed the issue, everything working nice.
TLTR: no Solution in Software, it’s a faulty USB-port. change it.
Have a nice day.
