So, here's the deal. I have a Motorola Backflip, it has been rooted and now runs 2.1 instead of Android 1.5. A few weeks ago, I woke up after charging my phone all night and it was very hot. It wouldn't turn on, I panicked, then later I tried and it was fine. Now, it happened again this morning when I woke up. It was very hot, I waited for it to cool off, and tried to charge it again, because it wasn't charging all night. When I plug it in, it recognizes it's plugged in with a little vibration, does the white screen with the Motorola M for a bit, then shows the "0%" screen with a charging battery. Then, it vibrates to show it's plugged in, shows the white screen with the Motorola M for a bit, then once again shows the "0%" screen with a charging battery. It keeps doing that, and won't charge. I obviously can't turn the phone on since it will not charge, and the battery is dead. I am using a normal wall charger, but I will try charging it through the computer to see if that makes any difference. Any suggestions? Is my phone okay, or should I give up?
U need a new battery

Just woke up to the very same thing with my backflip. It may have something to do with the amount of current going through the connection. I had mine plugged into the back accessory port on my old Blackberry Bold dock. The one that has a spot for the bold upfront, spot for a bluetooth headset, extra battery charger and an extra USB port on the back(I use it and my old Bold as a bedside alarmclock/internet radio now .) I had been playing a bit of leaf green on gameboid last night with it plugged in and woke up to a feircly hot Backflip that would not power on. it was on until I picked it up then turned off. i hit the power button and it just kept cycling through the moto M logo and then returning to the 0% battery screen and then off. i disconnected it from there, plugged it into my laptop where i could only get the micro-usb led to blink... it would not power on at all. I then got my Blackberry Torch's little usb wall adapter and tried that out and it worked like a charm. phone loaded up the way it was intended to.
Now as far as amperages go, for the dock i am unsure, it states on the wall plug it has an output of 1600ma, but for up to 4 devices... i am unsure as to how much power is restricted to each port if any. I only had the bold and backflip connected to it. My laptop has powered USB ports which deliver 550ma's each which is typical and in my experience often not enough to start a device from 0%. My BB wall adapter is 750ma's which has to be my personal preference. I actually refuse to plug my Torch into a USB port until i know it does not supply over 750ma's for fear of ruining my battery like had before on other phones not designed to use a 1amp charger. I am assuming my Backflip has the same idea.
Hi, All,
I was charging my phone in my car using the original charger cable but the car charger was not OEM. At some point, the phone stopped charging and it was still on. By the time I reached my destination, the battery died out and the phone switched off and hasn't switched back on ever since. I think the charger slot has stopped working.
1. Could that be it? Will a simple charger-slot change fix my phone? Or could it be something serious (motherboard, battery, etc)? I personally think that it could be the charger slot since the battery died out and then the phone switched off and it wasn't abrupt—which would be the case if there was an issue with the motherboard.
2. If it is bad news, is there any way to access my data? I have some important documents and photos in the phone that I don't want to lose so any way to extract the data from the phone would be useful.
I tried holding vol up + power button, tried connecting the USB cable to PC and switch it on, tried leaving it on charge for 4 - 5 hours and tried switching on, but all in vain. However, if I connect it to the charger and leave it on, the camera part will get heated up. The LED light indicating that the phone is charging will not light up though.
Do let me know if you guys have seen a similar issue. TIA!

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.

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.

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.
So from the beginning of story, my wife discharge phone to 0% and it turned off, after it turned off it wont charge any more, so i think she killed the battery. Bought new battery, replace and it's ALIVE, but when i connect fast charger xperia turning off ( puff black screen, on normal charger is showing it's charging and after 10 seconds puff same result ) and red light is on at the top ( new battery is 50% charged ).
So i connect old battery to Xperia Z1 and charge, old battery is working, connect to Z3 and it working without charger connect, when i connect charger phone turning off, and place where is connected battery to phone board getting really HOT when charger is connected.
I don't see any water on phone-board, and white marks near the place of connection with battery.
Have someone same problem, and have a solution?

Your charging module might be damaged. Try charging using the magnetic charger, it should work.
I have the exact same problem in my Xperia Z3 D 6633 . this is how the problem started. original battery started swelling but charging while it was alright and had charged but I saw the risk in keeping a battery that is swelling all the time so got a new battery and that second battery lasted for about 2 months after which one fine day it used to discharge in just under 20 seconds from hundred percent 20 and after that gradually it will not take any charge but at least I could make it pretend charging when I connected to AC and the phone was on as long as there was external power either from the AC or Power Bank. next this second battery was changed to a third battery . with the third battery in place all I could he is a red light there is no charging at all and no charging icon and phone is totally dead with a red light.
some other place I read that there should be a voltage difference of at least 4.2 v for a battery to work in that phone and III battery initially did work but when it was discharged it will simply not charge again.
when you say the charging module is not working what exactly does it look like and can it be changed easily please help me out thank you
I have replaced the screen but the cable flex of the battery has broken. The phone don't respond NOTHING plugged to charger or the pc.... NOTHING.. (edit: red light only for 1 minute or 2)
I don't want to buy a battery if the phone is broken, or the new screen is not working....
Z3 must boot plugged to pc without battery connected?
Thanks
