battery problem....wont charge if 0%

ok, on my xda mini s, if i plug the charger in at 2% to 99% it charges fine
but, i let the battery go so dead that it wont charge. so i bought another one and it did the same
is there a software fix for this? can i charge the batteries another way? both are only 6 weeks old and charge fine in my mates mini s (one of the first ones) mine is only 6 weeks old
its now getting very annoying
thanks

What are you running? G3 or G4, IPL/SPL, ROM version??

hi mate
ipl 2.21.001
spl 2.21.001
gsm 0.2.07.10
os 2.21.4.1
so just to clarify, I think there needs to be a tiny amount of power the the device to power it enough to recognise the charger is plugged in
i have 2 batteries with 0% energy - none will charge. The 3rd battery charges fine if more then 1% is left before I stick the charger in
thanks

Actually my boss had the same problem with his 8125. He was running wi-fi & music and it killed the battery all the way dead. I don't think there's a fix. He had to buy a new battery.

Looks like mfrazzz has the answer!

wow, ok i am a nuby and you might not like the solution but, every time my battery runs out completely and i cant charge it, disconnect the charger trust me on this one, lick the top of the charger connect it back and at first it will show a red light leave it there for about 4 minutes, then disconnect it and connect it back and your battery will start chargin again. trust me on this one ive done it like 4 times.

Dude!! I just have to ask...
HOW DID YOU FIGURE THAT OUT??? I mean, where you just sitting around thinking... Hmmm... I think I'll lick the top and stick it in.. hummm... I guess I'll leave it in for about 2 min... no... 3 min... oooo I think 4 min would be perfect.. then I'll unplug it and ummm... plug it back in!! Oh yeah!! That will do it!!!
Just kidding around!!!

wow, amazing stuff thanks
can i get an external charger/docker for the batteries?
do ALL these devices have the same problem or just the newer ones? my old one didnt do it (unless it still had some power in it)
Thanks

There is both a battery charger that you stick your battery in and a cradle that charges both your Wizard and also has a slot for a second battery. I couldn't find the single battery charger, but the dock can be found by searching for 8125 twin cradle.

hi mate,
my battery does not have any markings to say + and -
do you know which is which?
thanks

Ok, on my 8125 with the battery oriented exactly how it sits in the phone, the + is the top most contact and the - is the bottom most contact.

Here's a pic of a battery I found and you can just make out the + (red) / - (black) on the pic.

im not trying to ruin this great party, but were you trying to charge your MDA with the USB cord after you drained it? cuz u have to charge by A/C....
ohh and that licking thing....it works with AA batteries, 'cept you put them under your armpits for a few minutes

Help - charging notification?

Hi,
I have just started to try my first charge on my HD. I have not got the sim card or memory card installed, just the battery.
Should I be seeing some form of light or something when it is charging? As at the moment nothing seems to be happening, do I need the sim card & memory card installed to charge the phone?

The charging light is on the power button.
You should see a tiny LED at the power button. You may refer to the manual for further details on the colour and notification of the LED.

Well it looks like the plug in charger doesn't work . The actual USB cable does work though. Bloody annoying cos I will have to return the phone to get a replacement.

Hi AFK_Matrix!
my plug in charger didn't work either. Had to hold the usb cable at an angle to make it work.
I sent the charger and usb cable back to Clove and they sent me replacements by return of post.
I guess they took those out of a new box, put my faulty one's in it, and sent it all back to HTC.
Ofiaich

Well I just hope that Expansys are as nice as Clove!! Really don't fancy returning the whole phone!!

Hi AFK_Matrix,
I hope so too, I made it clear to Clove that I like the phone and do not want to be without it. I also said I would do a factory store and ask for a full refund, because I was within the 14 day period.
Good luck

Don't jump to a quick conclusion of returning your Phone.... See my topic ' Intermittent ReCharge Light'.
It looks like you have the same problem.
The only workaround I have found is if no light comes on, power the Phone down and then reconnect the USB power charger.
Plug it into the mains electric charger and you will then notice the red charging light will come on.
I have not found out yet what is causing the error but it does appear switching the phone off followed by connecting to the charger then makes it work.
Note: Once you have the red charge light showing you can then switch your Phone back on again if you want it operating whilst charging.
Me..... I just leave it off whilst it's charging as it doesn't take long and at least doing what I said above you do get the light changing from red to green when it is fully charged.
Beards.

Thanks for the suggestion Beards but I actually had the phone off when I first plugged it in and have tried wiggling the cable and pushing the plug in more etc and its having none of it!! So I am charging it via the computer, will be on the phone to expansys on Monday morning.

So sorry it didn't work for you.
Such a shame for you....... my heart goes out to your concerns.
Beards

Just thought I would give an update.
Just phoned up Expansys and barring any problems a new Charger should be with me by tomorrow or Wednesday. I didn't have to return the broken one either!!
I am feeling very happy that I went with Expansys, sure the deal may have been a bit more expensive but the Customer service of Expansys has been faultless!!! Plus I am only on a 12month contract so can change plans, providers etc next November.

That's great..... I just hope it was the charger and not the USB cable that is causing you grief.
....or worse it's neither!
Please do let us know. If it works I will be on the phone to Clove to request the same.
Beards.

Hi Beards,
Nope definetly not the cable as it charges fine if I hook it upto the PC. Its just the bit that plugs into the wall socket.
I will let you know when I get the replacement if it works (touch wood it does!!).

Fingers crossed for you mate....

Well looks like I spoke to soon. Just had an email from Expansys saying that they can't send out seperate parts and that I have to return the whole unit .
Just gotta confirm with them about payment for me shipping it back to them.

This seems quite drastic for what is needed.
Why not try and source a USB charger off the internet.
You can pick them up on ebay for just a couple of pounds.
Beards

Hi Beards,
Well I was a little annoyed too about having to send the phone back. So was in the middle of replying to the email saying that I really wouldn't want to return my phone but if I had to then I didn't want to have to pay to return it.
Then the phone rang and a nice gentleman from Expansys phoned and said ignore the RMA email as he was sending out one of Expansys's generic chargers to me I have just now recieved an email order confirmation for this charger.
I tell you Expansys haven't put a foot wrong yet!! (Touch wood this continues)

Hopefully the generic charger should do the trick.
I remember my Mio A701's charger wouldn't work and I got hold of one of these generic USB chargers and it did the trick.
What I found was the charger that came with the machine simply did not have enough power to charge the phone......

USB connection physically dead; not charging or usb to pc connection

Hi everyone!! i'm desperate since i think i came with an expensive, unusable phone in my hands.
I read and searched thorough but there doesn't seem to be much clue on this, just one or two lost threads....
Someone care to drop a hint to help me ? ive lost all hopes.....
My x10a, after using it for , say, 1 month, rooted with latest xx23 firm (and used for a week or more , perfectly fine) ... some days ago, it stopped recognising USB port.
IT does not charge, with no existent charger or usb cord; it does not recognise usb connection of any kind, to any computer possible.
It lasted till last battery charge died, and no way to resucitate.
Afterwards, i came up with something: i bought a crappy, chinese battery-charger, drop my X10 battery overnight, and the phone then booted and worked fine.
So it is the USB connector/port/circuit. I even though of reflashing or re-rooting, but you can figure out that i can't do that anymore (no usb :S).
I can't give it back to SE or seller since it was brought overseas, and it even has some little marks on the corners (they'll just claim i dropped and so).
Any caritative soul please?
I opened following McKebapp guides, but didnt find nothing in particular.
Do you think i should risk in getting hands dirty and, say, re-solder an usb jack?
If not, i offer in sell all spare parts, almost new, or even sell it at a very good price, e.g. for bootloader experimenting....
Thanks !

Are you sure there is no gunk in the port or the cable's contact itself? Or even a bad cable?
Try this.
(1) Buy yourself a can of contact/electronics cleaner spray.
(2) Remove battery from phone to ensure you have no power going through there.
(3) Spray area clean and wait for it to dry.
Afterwards put battery back in, power up and plug in. See if that works

Yes, i tried all these... but nothing... Of course, i tried using up to 10 different usb cables, even bought new ones... but the strange thing is that nothing really happened, in order to mess or 'break' something on the phone...it was from one day to another... strange....

I wonder if the port is soldered to place on the board or is just spring contact based. I believe Bin4ry had his phone disassembled - you can ask him. If it is spring loaded contacts - there might be dirt underneath that needs to be cleaned up. If it is soldered - a joint might have broken and need resoldering.

OMG... NEVER do that to a PCB with BGAs...
You'll shorten the connectors underneath the BGA soldered chips by fluid that stays there thanks to capillary action.
@rodrigofd:
Here you can see the USB connector itself, on the very left side:

IF there is any mechanical failure, one or more of the five solder points in the middle of the connector is loosened.
But I can't believe it's a mechanical / solder problem.
Wiggle the USB charger cable a little, while having it plugged.
That way, you'll determine if there is any hairline crack.
If there is any, you can think of resolder it..
If you ask me, I'd say, some SMD fuse has blown up or there is an hairline crack between the PCB layers.
To determine that, you'll need a 3rd level schematics and some electric circuit reading knowledge.
If nothing helps:
Wait till there is a OTA Update that unroots the phone.
Then bring it to service..

The same thing happened to mine. While it was charging on my desk, and I was asleep.
I woke to find the phone on the floor but the USB cable was attached.
Using JuicePlotter (which had been running) it seemed that the phone had stopped charging around the time I had missed a call.
My detective skills allowed me to deduce that the phone was fine, but then when it rang - and started to vibrate - it rumbled its way off my desk. I believe it was not hitting the floor that damaged it - it's carpeted and not much of a drop - but the shock to the USB cable port as it swung itself off mydesk, effectively "hanging" itself.
I'm afraid I had no luck fixing it but it was only a week old so O2 replaced it immediately.
These days I ensure the phone is FIRMLY wedged somewhere when charging it.

Nexus 6P doesn't turn on

Got phone from Bell on a 2 year contract about 8 months ago. When it arrived I put a glass protector on the screen and the Unicorn Beetle (the tougher one) on right away. I've been very careful with it since.
It's worked fine until I joined the Android N (via the Beta) where I found the battery drop quicker than normal.
While the phone was at around 30% charge, it suddenly turned off and would not turn back on.
I tried following these steps to fix it. No luck.
QUESTION: I called Huion to get it serviced since it's still under the one year warranty. They said that if the phone was rooted to not bother sending it in because they would know. Based on all my research, I have no idea how they would know. Would they really?
SYMPTOMS:
Phone does not show anything on the screen.
I bought a new charger and cable and have been doing different tests and have been getting no luck.
When I plug my phone into my computer I get this error:
"USB device not recognized. The last USB device you connected to this computer malfunctioned and Windows does not recognize it. Recommendation: Try reconnecting the device. If Windows still does not recognize it, your device may not be working properly."

Once its plugged into my computer and i hold down the power button i hear my computer make a sound to indicate that a device was unplugged and replugged back in. But Nexus Root Toolkit or Vysor does not recognize the phone at all.
Nexus Root Toolkit does not detect my phone.

If your image when you turn it in is still unlocked and rooted or even locked and rooted they will know.
Are you able to get the phone to turn on?

See if you can get the phone to bootloader mode. You can try the Nexus root toolkit to go back to 7.0 stock.

I see my original post was not clear.
Nothing I do turns the phone on.
I tried every step on this site, all with no effect (phone stays black)

Recommendation: Try reconnecting the device. If Windows still does not recognize it, your device may not be working properly."

You need to charge it..
Powering off at the 30% mark is a known bug to some running 7.1.1.
It happened to me all I had to do was hook up the charger and let it charge then it will power back on.
This only happened to me once and some others as well

I had it plugged into three different chargers (including the official one), with three different cords, each for over three hours (often over night)
No luck.

You may have damaged the USB-C port. The only time I've seen that Windows error was when I damaged the USB-C port on my laptop with a slightly crimped USB-C connector that I didn't realized was damaged. After damaging the port, I changed cables to one that was not crimped, and I saw that error because of the damaged port. So I'm thinking it's possible you may have damaged the port on your phone, and it's not charging. Hard to say. Just trying to help. Look closely at the port with a bright light and see if you notice any damage.

You tell me? http://imgur.com/a/NlOxv
I have tried three different cords and chargers btw.

I can't tell from those photos.....probably no way to get a good enough shot. I was able to compare my damaged USB-C with an undamaged one, that was really the only way I could tell. I could see there was some slight but noticeable damage to some of the very thin wires surrounding the wafer in the middle of the port (best I can explain). Need a bright light to see well enough.

Nexus 4 Not powering on at all. Battery dead or phone dead?

Hello. Recently I decided to pick up my old Nexus 4 again and try seeing what happened to it.
I was using my Nexus 4 one day and dropped it from my bed, about a foot or so, and it just cut out.
I opened it up to find out that the battery cable had snapped because I had done an earlier battery repair, and forgot that I should have let the cable slack a little bit.
A few months later I get a replacement battery, and tried booting on the phone. It would get to the lock screen and say the phone is critically low, and shut off.
TWRP said the battery was at 80% charge, but the UI was flickering a bit. I asked the XDA Discord and was told it was a storage failure.
A few more months pass by to now, and I decide to try and revive my N4. I want to see if maybe the battery was seated wrong, it could've been.
I reseated the battery and tried plugging in the phone. Now, I get a solid red light, that changes to flashing, and then nothing. or a flashing light that stays flashing.
I have not gotten past this. Is the battery toast, or is the phone toast? Can I test the phone without buying another replacement battery? Thanks.

You can try getting a V+ measurement from the battery to get an idea of it's condition.
If it won't charge it's cable or connectors may be damaged.
Even if the battery failed it should take some charge. Obviously it's producing some voltage but maybe not enough to boot.
If the battery seems to take a charge allow it the charge overnight and see what it's voltage level is. If it still won't boot it's either the battery or hardware damage, but doing this would give you more information to make a call.

I've left it on the charger multiple times, and the phone seemingly doesn't do anything. never gets warm. I tighened down the connector screws and am using a cable I know works. I'll try to get a measurement from the battery.

Check the other ribbon cables, port jack/pcb, mobo etc. carefully for damage or looseness.

UPDATE:
I was able to get the phone booting, but now when i try and start android it immediately says "Power Off" "Shutting Down"
now what? bad battery? it's plugged in, it shouldn't do that.

May be the battery as it may draw quit a bit of current when booting.
More than the charger may be able to sink.

Yay!

Phones working, forgot to say this on Monday. Although the battery percentage is fluctuating after charging overnight under LOS 15 and 17, no clue why.

New battery's dead. I'll try and get another.

I know this thread's old, but i'll just update my results with this:
She's cooked.
I got the new battery, worked fine for a bit, but the battery percentage was completely jank and would go up and down. Not too long later, it doesn't even boot. I'm guessing the EMMCs fried. If I find a smashed up Nexus 4 locally i'll for sure do a mobo swap since mine's in really good shape physically.
