Battery wont accept a charge - Xiaomi Mi A2 / 6X Questions & Answers

My A2 no longer accepts a chare and continuously drains its battery.
The issue is my own fault, as I used chargers that did not have the same specs as the phone.
Im wondering if anyone else ran into this issue and how they solved it.
I took my phone into a shop. After their diagnosis, it turns out its something wrong with the mother board, and not the charging port or battery.
It would be cool if there were some sort of software fix for this, but probably unlikely.

[Q] Salsa touch response works weird while charging

Hi,
I have this strange problem happening since yesterday on my brand new Salsa. When I put it on charging and leave it on a wooden table, the touch screen responds weird to my touch. The ring lock will not open all the way or shortcuts will work weird. The soft keys at the bottom too go absurd not responding or giving different options.
If I pick the handset (probably providing grounding), everything works normal thereafter. I'm using only the original charger provided with handset.
Additionally even the sound into my car's auxillary port is behaving as weird filtering or dimming the vocal frequencies but allowing the music to get through.
Does anyone know why this is happening?
Only incident to have caused this I guess is when the sales guy I went to plugged the phone onto a blackberry charger yesterday for a few seconds.
Could it have caused some damage to some internal part - diode or something that is leaking AC voltage onto the capacitive screen ? Can I have it repaired at HTC ?
Since it's not even a week old, I'm too distressed about the weirdness. PLEASE HELP!
does seem like it could of done some damage as blackberry's do take a lot more juice than the salsa, personally i would take it back and tell them about the problems you have had only since the dude abused the phone lol
I will surely be taking it back but want to confirm if its the problem with the phone or charger, because I do not see this problem when I charge from my laptops USB.
And I want to know what it is before I take it to them. Its much safer to find the problem and tell them rather than allowing them to figure it out themselves and in turn damage something else.
Thanks
your laptop will deal 5v 1a max before the computer will cut off the usb supply due to risk of overload, new blackberry chargers deal a lot more than that due to the juice the device needs to charge, almost like different laptop chargers the difference in the supply would kill your laptop, i don't have any problems with my device regardless of surface it is resting on.
I have the same problem
I have the same problem, but it was observed from the time of purchase. So do not worry and take the phone in hand))
Resolved
With some searching I resolved this problem or I can say I at least know why this is happening.
It is the charger that is faulty and not the handset. I changed it with another HTC charger I had and the problem disappeared. I figured the most logical explanation is what I read in one of the post elsewhere in this forum.
The charger could be faulty to be leaking some AC voltage along with the charging DC juice. This leaked voltage interferes with the sensitive capacitive touch screen. If we hold the handset in hand, we are providing a natural grounding and hence the problem disappears.
I personally would not like this to continue and so I'm going to take it back to my vendor for replacing the charger or if the need be, buy a new one.

Try using another charger and see the difference. Hope you can get your charger repaired or replaced!
Take care.
this is due to a grounding problem or/and leaked ac current....
This problem occurs when your charger supplies more power than required by the phone to charge.The only solution for your prolem is changing your charger.

I had once another problem, that my Salsa overheated (red-green blinking) when I charged it and my Wifi was on. Maybe a background-process could be responsible.

Phone repair Batter or Charge port problem?

so basically my phone stopped charging after two to three days because it would just charge slow but then charge fast again then charge slow again I don't know if it's the battery or the charge port but yeah that's what I'm trying to find out also whenever I did check the battery capacity it would say that it's at 2800 and then it would just say like in th system settings it would say Null Mah. If anyone knows what it could be it be nice to know and also best place to get replacement parts fast.
i have the same problem
Apparently its a common problem for Xiaoi Phone. Trash company. Chinese trap.
Did you finally find solution?

Hardware defect - Battery or Mainboard issue?

Hi guys,
I had to change both display incl. frame and battery because a barbell fell on my Mi9. This bent the phone at the place of the battery and completely destroyed the display.
I was able to repair the phone quickly, but unfortunatly I did not glue the new battery. Now I was mountain biking and due to the vibrations the battery was torn from the mainboard and parts of the battery cable got stuck in the connector. I had these parts removed carefully by a watchmaker and he assured me that the connerctor looks undamaged.
But now I have the problem that the phone won't start when I insert the old (minimally) bent battery. It does not respond to any input. Only when I charge it, the LED is blinking slowly and the MI Start logo appears for 1/4 second. This process is repeated continuously. The battery also warms up slightly, showing me that it is being charged and that the connection is basically established.
Can you detect a defect on the board by this error description or is this a "typical" battery problem? Or does this error description look familiar to you otherwise?
Thanks for all suggestions,
Mike
Well I'd say that will be a hard problem to diagnose without knowing what to look for, and I definitely don't know but what I'd suggest so you can rule out the battery problem is to try a different battery in the phone and see if you get the same response. If it works happy days problem solved. If not it is more than likely a main board problem or charging connector.

Wireless charging stopped working 4 XL

I see on some sites that users are reporting this and some think that it's related to the security update in March. That seems to be when mine quit charging wirelessly on known-good chargers.
On mine, it intermittently will never handshake with the charger, start to charge then lose connection or never charge beyond a certain point.
Wondering if anyone here is having this problem.
This sounds like the issue people have had with battery connector. There seems to be a faulty battery connector or easy to break small piece. Many have reported this and have had to either fix it themselves, get another unit or pay to get it fixed. Search around you will see what I mean. I haven't heard anything about an update causing this. I have heard that there is a piece that connects battery to phone that breaks easily. I've read quite a few reports of this and how a slight drop can cause it to break and cause charging issues... Read one person put a piece of electrical tape on it and fixed it that way.. idk. That probably doesn't help much. I hope you get it fixed. If you think it's March update and want to rule it out install April update.

Check for a swollen battery. On mine the glass started to separate near the volume buttons. I didn't find it until I took the case off and inspected it carefully. I was able to get a free replacement. There was extended coverage for 4XL battery issues... maybe still available. My issue was not the same as the battery connector issues also documented on XDA.
Erratic wireless charging and swollen battery
This issue is related to the battery, but not the connector issue others are having. About 3 weeks ago I started experiencing erratic wireless charging. Sometimes it would be fine, other times it would just stop for no reason, or not even start...

That was it exactly.
I talked to them and they escalated me to the "product safet6y team" and I'm waiting to hear back from them to see if they will replace it.
I was heartbroken when it lost wireless charging because I really wanted to keep this phone as long as possible and hated that something was broken. It's almost perfect in every way (and no notch or punch-hole.)
I also had the Soli unit go bad and they replaced my phone early on under warranty. I think LG did a great on these as the ODM, but it looks like their component sources were the problems.
Thanks again for the excellent help.
So I was having the same problem. I had to pop the back off my phone. You can see where the wireless charging pad has a spot where it contacts two pins on the phone side. I bent those two small pins slightly upward and put the back back on. YouTube how to get the back off I only used a small pry tool and my fingernail to bend the pins. You don't need to unhook the back. You can do everything with it connected.
Go slow be careful Good luck

suddenly stopped charging

Yeah as the title says, my a71 suddenly just won't charge.
last night I had a smooth charging experience. I was even watching Netflix with this phone in my hand, and it was charging. nothing's loose. no disconnections.
but today, I'm trying to charge, nada. Tried restarting etc. still nothing. even went to safe mode, still won't charge. there was no issue with the charger too, I checked. And yes, the charger and the cable were original ones, not replacements.
I'm worried right now because it's almost dying. It's not even a year old.
Pls help. Thanks.
I really don't know about this one you should contact the store you bought it from and tell them that and they should send it to service for free, from what you said i think somehow the charging board died or had a short circuit somehow.
your charging port is dead. happened to my A70 as well. had it fixed under warranty.
