Phone starts only if connected to the charger?

Today I had the experience of having this problem
I've read in several places about it, but he is already well known
My experiences and attempts:
*disconnected from the charger it goes into bootloop
*connected to a charger it turns on and works normally
*loads very slowly (original charger and cable)
*battery percentage is crazy (for example to restart it jumps from 14% to 76% and otherwise)
*when disconnecting the charger it works for about 1 or 2 minutes and turns itself off

as well as several people have noted, it is a battery problem!
Maybe any particular type or configuration and calibration? I do not know!
among several people who reported this problem this is what catches my attention:

However I will send the set for repair (still under warranty)
any feedback is welcome!

This happened to me! My had ZL had already been replaced once and after about a month it started showing the same symptoms. I flashed the stock firmware twice just to be sure it wasn't a software issue, but the problems persisted.... So i took it to the service and now they're gonna replace it again (obviously without any charge)! It is a battery problem and hopefully I won't have to go back to the service center with the next replacement.

Yep, exactly the same as my case.
When the replaced cellphone had the same problem, I called Sony and they wanted to replace It again.
I said I wouldn't send it for replacement because the (then) third one would have the same problem and I would have to wait another month or so without the cellphone (not to mention the warranty was already at half).
I requested the refund, they did it in 2 weeks if I can remember correctly, then I waited 3 months with a crappy phone and now I'm a happy owner of a LG G3.

i had sorry for you and in some cases were in the same boat..
My battery also crazy, sometimes it went down to 14% from 92% and sometimes it's dead when it reach to 70% and below..
i know fully discharge and charge again would fix this but it wont be long.. It's gone for about 3-4 days and later.. My phone went drunk again..
in my mind, i looking for a phone with removable battery (samsung is my quick choice). But it's hard for me to leave sony and hard for me to leave "a full of memory phone", my xperia ZL..
i been using sony (ericsson) since K800i was released till now.. The XPERIA ERA was coming..

my warranty will expire in about two months
assuming he was sent to warranty I would have to have this extended period... huh?
I will make it clear to receive the product back if he face the same problems will want a refund
even if need to seek my rights
this problem needs a "recall" (since many people had this problem and was contacted)
consumers would look with brand new eyes

hi, forgive my english, is my firsth post...
This a alternative fisic metod to saved the battery,
my c6506 now work fine!!.
the problem is the battery flex, is a defect in the negative of the battery, n is solved by a fisical "jumper" to the negative terminal to negative flex terminal, as show:

great news friend, it may be helpful to me if a new problem happen in the future and certainly many others
(My conclusion so far) this problem happens when the device reaches high temperatures that eventually comes to corrupt welds trails Battery

Funny, I've been assuming the battery failure was the result of a thermal fuse getting popped by heat...
That being said, I THOUGHT mine had died this afternoon, but not it seems to be working again... we'll have to see...
Sadly, I'm unsure that my receipt from the bitcoin store included the serial# for my phone...
I was wrong, it's dead... Not cool...

My RMA is setup and I'll probably ship my phone out tomorrow...
I'm not certain I would consider replacing the battery an adequate fix as this seems to be a flaw in the design... thinking I might just try and sell my phone when it comes back and move on to something else...

thanks

HI there,
I had the exact same symtoms.
RMA and battery replaced by Sony. I droped the phone at a Sony store to save shipping and they sent it to the repaid depo.
Got the phone back in 10 days.
works great (except for 4.4.2 play services bug)
Bonus, sent it in with:
Boot Loader Unlockable: No
SIM lock: Rogers (in Canada)
Got it back:
Boot Loder Unlockable: Yes,
SIM lock: NO
thanks again Sony!!!
if you still have warante, then send it in. My screen has a small scratch, so I know Igot my original unit back.
Good luck...

Thanks man, excellent tip... I was able to save my battery :laugh:duh

I found it interesting when I got mine back from the repair depot, they'd replaced ~ 4 screws, ~ 3 strips of glue tape, the battery, and the grounding strap...
I need to roll back to 101 and test - I don't seem to be getting DC connections in places where I didn't get LTE... in fact, at this point, I seem to either get LTE, or no data at this point... which is very strange...

Battery Reporting/Phone Dying Suddenly

Update 2: I've had requests for links for the parts I used. I purchased the battery, a back cover, and all the additional accessories they suggested for removal.
Battery:
http://www.witrigs.com/oem-battery-for-sony-xperia-z1-compact
Back cover (this comes in different colors, but the link is for the black one):
http://www.witrigs.com/custom-back-cover-for-sony-xperia-z1-compact-black
---
Updating the OP. Thus far the only reliable way that myself and others have fixed their batteries has been by replacing them or having the phone repaired by Sony. Fixing it yourself involves purchasing a replacement from witrigs (or another parts supplier).
Flashing stock roms, custom roms (aosp or cm based), or factory firmware may temporarily give the illusion of being fixed. Battery repair apps don't do anything either (you can test this by 'fixing it', clearing app data and then 'fixing it' again).
I'm back to KitKat levels of battery life, using stock 5.0.2. Here's a recent screenshot for you.

Original post:
So for the past few weeks my phone has really been acting up. I'll try and make this an organized question/post.
Here's the symptoms:
-Phone drops from 30ish % down to 1%, then powers off and wont turn back on due to low battery.
-Phone occasionally reports fully charged at different levels (such as 80% or 50%), upon reboot, it is listed as 100%.
-Some days I can watch it drop 1% every few seconds once it reaches 35%, literally like it's counting down.
-Other days it just works fine, I can use it to 5% and then charge with no problems.
Phone information:
-Z1 Compact
-Problem persists between ROM flashes and android versions. Have experienced issues on stock 4.4.4, stock 5.0.1, AOSP 4.4.4 and AOSP 5.1.
Really, any sort of help or places to start would be greatly appreciated. I don't even know what to try anymore and I'd really like to avoid trying to replace it (warranty expired already).
Attached a screenshot illustrating it happening. I unplugged my phone last night after charging it to full. Made it to work, put it in airplane mode, turned wifi on. Updated some apps and restarted it. Rebooted to about 10%. Charging again now.

HI There,
i got the same problem with my z1 compact. its all start when upgrade to lolipop...
some say our battery are dying...or got problem. are they ?
downgrade to kitkat, wipe everthing, battery calibration also still the same problem appear...

I've tried the same thing. Wiped data system etc and nothing helped.
Sent from my D5503 using Tapatalk

Same problem here. 4.4.4 stock rooted. It started about two weeks ago. I had done nothing except some play store upgrades. Haven't found a solution and I don't even know how to diagnose the problem. Various battery calibrations and/or deleting that battery data file haven't helped. Did a factory reset from recovery (almost accidental swipe while a bit drunk, gah...) - nothing. Battery level drop and shutdown occurs in random situations. Sometimes while taking a picture, sometimes with data on, sometimes off, gps on/off or whatever. Sometimes from 70% to 0, sometimes from 50%. Sometimes I can restart without charging after waiting a while and then it stays of for some time.
Yesterday I just did a reboot myself and when it came back on, the battery had dropped from 70 to 20% and then it stayed like that for some hours. Then I let it run to 0, charged without turning on to 100%. Then, when I turned the phone on, the battery level dropped to about 80% really fast and after that I got 20+ hours until it died again at 55% battery. I do see some small temperature spikes on Gsam battery monitor graph during those sudden drops, but never above 35 degrees Celsius and I don't think overheating is the issue here.
Again, I hadn't flashed any roms, updated android or messing around with the system or system settings before it started. Just normal everyday use, some websurfing, listening to music, taking occasional photos, reading blog feeds, taking notes.
Now I don't know what to do and I would greatly appreciate any help.
Haven't tried software repair yet, but what software could be still left broken?
Should I try unrooting via flashtool (does it lose all traces of root?) and taking it to warranty repair?
Right now the phone is practically unusable.

Hey, did u checked the Service menu Batterie test?
*#*#7378423#*#*
*#*#SERVICE#*#*
What does the test say?

I did check that yesterday and it was good.
And at the moment batt health status is "good, no need to replace it".
(Actual batt uAh: 2407000. Battery gauge at 74%.)
Yesterday after recharging and watching the battery plummet to 83%... It stayed there for some time despite data and GPS being on, using camera and an app. Should have dropped by a couple of % at least during that time.
13+ hours uptime now, very little use at night and at work.
That's what I'm afraid of. If the service test is good and at a glance everything seems to be fine then I won't get any help from warranty.

when test mine also in good condition. but the problem still happen. it kind makes me to conclude possible a battery hardware problem. need to change it, but it aint that cheap...

I've also checked my battery in the service menu. It reports good/healthy with the actual uAh being 2407000. I plan on wiping everything on the phone later today (system, all data, caches) and seeing if that helps at all, but I'm not very hopeful. Like you guys this pretty much just started happening for no discernible reason. Phone doesn't appear to be overheating either. Could the SD card being messing with it somehow? It seems implausible, but at this point I'm willing to try anything.

SOLVED (for me at least)
So I bit the bullet and wiped everything except for my SD card about 2 hours after my last post. Installed the most recent KK version of DstrikerZ1s ROM with the Doomlord v22 kernel. Ran it hard all day till now. Still at 50% and I've rebooted to check and make sure it's accurate multiple times. I'll report back if it happens again, but the performance thus far seems much more consistent than what I had before.

So need to format sdcard?
Sent from my D5503 using XDA Free mobile app

Yeah, I backed up both my internal storage and SD card and then formatted both.

wow, i have the same problem and i don't want to go back to KK. doees anyone have any solution that keeps lolli on?

I've been having the same problem since February. First it turned off at around 14% (when the warning pops up), but it's already been turning off at 20+ and finally 30-something percent, which wasn't bearable. No amount of wiping or up/downgrading would help so I bit the bullet and got a battery exchange (not directly from Sony who wanted to charge ~160€). Problem is fixed for the time being.
As much as I love this phone, it'll be the last one I get without a user-replacable battery.

Unfortunately my "fix" didn't work forever. I'm back to the same problem. Might as well suffer through it on lollipop. Where did you get the battery replaced?

Sent from my D5503 using XDA Free mobile app

exactly the same problem only since Lollipop update.
it'll just shut down about 30% battery now, no going into battery saving mode or anything, i'll just be messaging and get "shutting down". Also I've had 53% battery, rebooted and then have 80%ish, its completely messed it all up.
I've factory reset and cycled the battery (run down, charge full etc) more than once. I'm suprised peoples batteries actually need replacing, how can a software update damage the battery?
I remember with a previous rooted samsung phone you could delete a battery data file with root explorer or something, is there a similar non-root way to fix this problem?

Huge battery drain - Mondrianwifi

Hi guys, my tablet has been showing some significant battery drain lately. When idle, it drains around 5-10% per hour. At first I thought something was preventing it to go to sleep (according to GSAM the battery is mostly drained by the kernel), but then I started noticing that also when I was using the device the battery drained significantly (20-25% per hour).
I tried the common fixes such as wiping the device, turning off any energy-consuming apps and services (e.g. Google Now, GPS, etc.), battery recalibration and reseating the battery; nothing helps.
I'm running a stable nightly from CM13.0 (I asked in the CM13.0 thread if anyone else has this problem but it just seems to be me), but the issue was also present in other nightlies and in 12.1.
The last option I can think of right now is buying a new battery, but since that would be pretty costly and since I'm not sure that would solve my problem I wanted to run this by you to see if anyone here would have an idea of what could solve it.
Thank you very much in advance for your help!

Not ROM related. I am running CM13 and was having the same issues. Take apart the tab, and lift the battery connector vertically. There might be some tape, take that off first. Let tab sit for 5 min, then reconnect. Fixed my issues

Someone just disconnect and reconnect the battery to fix the problem, the white connector has loose connection,
this one needs to be fixed too by adjusting the opening tip of battery cables
Samsung fix the issue of loose battery connection by using this silver conductive glue
This is a repair from Samsung center, they soldered battery cables directly to the connector to fix loose connection,
without knowing this, an average user will damage the mainboard and battery connector while trying to remove the battery.

What you need to do is take the back cover off the tablet and look for the battery connector, it's basically a few bundled wires that connects the battery to the tablet. You need to disconnect these (I used a pencil to wiggle it a bit, make sure you do it carefully) and let it rest for about 5 minutes. After that, reconnect it and turn your tablet on. That should fix the issue that you're having.

Stupid question maybe, but could this loose connection also be a solution for the drain I'm having?

Your fix does seem to improve battery life a little bit, but unfortunately I'm still stuck with a pretty big drain. When totally idle it drains 5% per hour, so it dies after about 18 hours of being totally idle.
It should be able to last longer than that right? Any suggestions from anyone are welcome!

You should fix both battery connectors: black male connector needs to be re soldered, white female connector with 6 wires needs to be adjust the opening of battery cables.
Some may need to fix one, not both, but for sure, both need to be fix, the same procedures Samsung repair center will do: fix both connectors.
Regardless what model you have, the same fix applies to Samsung 10.1 and 12.2.
I have been fixed Samsung Note 2014 10.1 ( LTE and Wifi ), Samsung Note Pro 12.2 ( LTE and Wifi ) and Tab Pro 12.2 tablets, they all have the same problem of battery connectors.

how does it cost to fix it without warranty at samsung

It may cost you over $100 for a round trip to Texas.
Anyone or shop who can do the rework can help you with little charge as much as $60. It takes only 5 to 10 minutes to get it done.

Just outta interest, which 'Mode' are you using?
I've found the stock 'Balanced' Mode (cm-13.0), drains my T325 alarmingly fast.* Unless I switch over to the 'Efficiency' Mode, which seems (for me), to work like the old 'Balanced' Mode from cm-12.1 had.
*Alarmingly fast here would be a compleat drop from ~100% to Dead with in 90 minutes. Note I'm less sure if that's the nature of that Mode , or if it's just the stress of coming off a clean install, and the rebuilding the OS up again. But, since moving to cm-13.0 I've been sure to change up to the 'Efficiency' setting. And, so have been enjoying upwards of +7H of use.

Battery connector problems are not related to software or firmware; quick discharge, battery capacity fluctuations, long charging or never get full charge are all common problems of Samsung tablets regardless whatever you're running or settings

I was really hoping that that would've been the problem but unfortunately I had already set it to efficiency mode thanks for your reply though!
Although I trust my software capabilities more than my hardware know-how, the issue is getting so frustrating that I'll try Beut's solution. I will report back after I tried it!

[*NEW*] Nexus 5 Battery Upgrade! BL-T19 2700mAh Mod (nexus 5x battery)

The Nexus 5 was produced a while ago, more than 4 years!
But this phone is still fast and I'm using it as my daily device. But there was one problem, the battery!
If you want to replace it you still get an (if you're lucky) an original used battery. If you're unlucky it's a fake one or it was just lying around, loosing all capacity and is at least as bad as the battery you already have.
In 2013/2014 a lot of people managed to press an Lg G2 battery inside the nexus, the BL-T7
BUT this phone and it's battery is very old, like the nexus 5
I tried the BL-T7 Mod, after receiving a lot of fake batterys, I finally got an original one, but yeah, still a 3 years old battery, that was lying around - so it was not good at all, and I lost NFC and Wireless charging
See here: https://forum.xda-developers.com/google-nexus-5/accessories/3000mah-battery-mod-lg-g2-battery-t3651460/post73284739#post73284739
#############################################################################
Here is what I got for you:
On Ebay, I was looking for a new phone (because of bad battery life) and I found a perfectly fine looking Nexus 5x for 20€, the seller said it won't turn on. I ordered it and i did not manage to repair it, the seller just lied, bc he didn't say it was damaged by water
What I did: I saw the battery, thought about, "hey this is a 2016 battery, original and it may fit"
I ripped it out and really managed to swap this 2700mAh BL-T19 battery with my Lg G2 3000mah BL-T7 battery that was inside my nexus
And holy, THIS BATTERY LIFE! - 5hours SOT under heavy load!: https://imgur.com/a/sOdT0
https://imgur.com/a/HAm8e "normal load"
https://imgur.com/a/x2kXO min brightness, not doing much (only whatsapp), I know that is unrealistic, but at least, it's achievable!!
Benefits:
it's a new Battery (produced in 2015/2016)
NFC working!
Wireless charging working!
The nexus 5x had a lot of problems, a lot of dead phones, and if you're lucky you can buy a defective phone (like me) and get a fully functional battery!!
#############################################################################
NOTE: Use Tape, this is a powerful battery, if the wires touch each other, it may start burning
I won't take any responsibility if your phone get's destroyed!

and this is the one in the nexus 5 (BL-T9):
as you can see, the nexus 5x's is longer, but it's the same width. It's longer than the lg g2's one so i had to make space
I won't make pictures of my mod because i already did it, closed my phone and I really don't want to reopen it did it, see below (5.)
1. Completely disassemble your phone, you need to remove metal from the frame
2. Search a dremel to make space: I have no dremel so I used a DC motor and put sandpaper with zip ties on it (https://imgur.com/a/O7SIU)
3. Now remove metal from the frame, I have here some pictures on my testing phone frame: https://imgur.com/a/53tbX
4. Replace the battery! Do it exacly like here: https://imgur.com/a/Yj7ww
I won't decribe it any further, you may ask for help here or in older threads (Lgg2 battery replacement)
5. Here are some other Pictures I edited for you, the 2nd and third are the important ones! https://imgur.com/a/lpz8W
here are Pics of my mod, don't worry, mine looks a little different because I used another batteryboard because I broke my original one: https://imgur.com/a/8BLVj
6. You're done! try to bootup, close the phone, and be happy about a big battery NFC and Wireless charging!!!
Note that you may have to remove some plastic from the cover that goes onto the mainboard,

Did that mod yesterday, so I don't know yet
Update: I did my first full charge 2 hours ago, have 1h sot and still 91% left, holy moly
Update 2: 77%, 2.5h sot: whatsapp, browsing and youtube half brightness and an slight overclock to 2.35Ghz (elementalx kernel)
Will report tomorrow after a full day usage because for now i'm gonna load it overnight

Okay my test results are here!
https://imgur.com/a/sOdT0
My display brightness was maxed out most of the time.
5h Sot for an intensive workload is very impressive! I tried everything except gaming to stress the hell out of that battery, and it lasted so long!
I'm gonna test a normal workload and upload pictures here if you want.

wow great work!
I'm still using the hammy as my daily driver and using the first original battery.
will try your mod if I have time and the technician

https://imgur.com/a/HAm8e 7 ****ing hours!

https://imgur.com/a/x2kXO Wow.

.... That seems a little crazy for a battery that has only 400mAh higher capacity than the original 2300.. so.. a 20% boost?

Well, I undervolted and my screen was on low brightness
But my core clock is at 2.35Ghz
It was not a worst case, but it's real
and it's not only 20%, because the original battery is veeery old, you are very lucky if you get one with more than 1700mah left

I doubt any of us were getting 5-6 hours SOT even 4 years ago.. maybe, though. It has been a long time. I'm not doubting you, just wondering out loud how that works out since the math sounds weird.

Mostly it's because I really tried to get the best Sot, with using it not much. So my phone was a long time on my desk with whatsapp open, and I was only texting.
That's no usual usage, my usual usage was 7 hours Sot, still impressive

Looks difficult to replace mate

sure, it's not the easiest swap.
Bit if you can use a dremel and solder 5 cables there should be no problem
I did my mod in 2h
expect 1h because theres no need to try and error anymore

I picked up a 5x battery and was going to attempt this but holy cow, you have to make about 1cm of room from cutting the frame/plastic covers. That's far more material than I'm comfortable doing... I'd say keep looking for a similarly sized battery since you're manually wiring the electrodes to the mainboard anyway...

I think you didn't take a look at my pictures, you have to remove everything around it, and reassemble the battery board on the side, if you need one more centimeter, you did something realy wrong
I have an original 5x battery, and I can confirm that theres enough space to fit it in
EDIT: I reopened my phone to fix something up, I made Pictures: https://imgur.com/a/8BLVj

Poor device, looks fried

Ah I did miss that. Once I peeled the battery and swapped boards it appears to fit with trimming just the top and bottom borders.
That said, it still didn't work for me... I must've fried my board because it just keeps booting to the battery icon over and over, even when I remove the battery connections.
Also, in your pics you seem to only have two wires directly soldered to the three pads below the battery connector then another wire going into the battery connector itself... is that right?
Anyone know if there's a way to recover from the battery icon reboot sequence? I'm able to get to the fastboot mode, but if it tries to boot into recovery or system it'll just shut off and go back to the battery icon.

That's exactly the reason why I now use another battery board. I killed my original one and had the same battery icon reboot problem. And yes one wire is going to the battery connector itself because I broke the pin on the board, but don't worry, It's the same connection. So you can either use the pins or the connector or a mix between
To 'recover' your phone, try to just disconnect the third pin, this is the thermal sensor pin. It's on the board the very left one. Here's a picture with just the + and - connected: https://imgur.com/a/GVPMt

Great mod! I may try it when i get a nexus 5x battery. Btw, how are this golden "wires" called? (The ones that goes from the positive and negative to the board)

@234herobrine432
What wires did u use?

Not charging after battery and port replace.

Update:
Try clearing USB Settings cache, wipe cache in recovery mode nothing work but what makes some improvement was following these steps (us.community.samsungcom/t5/Note8/Note-8-Died-Unresponsive/td-p/235388) that refers to charge stacking I did plug it and unplug it many times like 100 without holding the buttons, first like 20 tries I got the charging symbol with the yellow warning, after 50 it star flickering like if the cable had a lose contact it was at least showing the %, after like 75 it start showing as if it charges normally will go up 3% and then like 65% 66% 67% and the over and over again 65% 66% 67% and after the amount of time past so the battery discharge 1 % will keep doing the same now like 64% 65% 66% that's where I am at the moment.
Tonight I will heat it up to try replicating the first fix trying to melt the USB port connectors looking for a temporary fix so that I can make a backup if not will do the backup with 60% the battery I have left from the new battery. :fingers-crossed::fingers-crossed:
----------------------------
Hi everyone
Like a month ago, my A70 (one of my best phones so far in terms of value for money) stop charging.
At first, I thought it was the cable, the adapter, so I try different adapter, plugs, and cables until the point that my phone battery got discharged.
Confident that it was not the battery I bought the charging port part and start heating the phone to disassembly and replace the charging port while doing that I receive an important call and left for a meeting when I come back I was preparing my self to start the heat process again. Still, for no reason, I connected to try one more time before surgery, and voila, it starts charging.
My only explanation was that the heat must have melted the USB-C connector soldering and reconnect, so now it was working. I save the part, knowing that eventually, the problem will come back. And it did, one month later the same happen the phone stops charging, the battery got discharged, and then I open and replace the USB-C port part. Still, it didn't work I connect the cable get the thunder icon but not charging, so I say it must be the battery get a new battery today replace it and is not charging just showing the thunder icon for a few seconds then the screen goes black, but the phone is not charging.
I turn on the phone, and all is working perfect, the new battery came with 80% charge, so I know all is good. I even try safe mode to discard possibilities without success.
So I don't know what to do anymore? I don't even understand what can be or even to what the problem may be related to. I start thinking maybe I should buy a new port part because the new one was faulty?
I will appreciate any ideas or help.
Thanks, and have a good one!

i have the exact same problem, and we are not the only ones , i should've brought a k20 pro instead , can't believe it passed tests

So sad to know we are not the only ones, I guess that it the price to pay for buying a 2019 phone is like using the last update of windows we are the ones that will end up solving and reporting all the problems.
I will keep searching if I find something I will post it here please let me know if you find something. In the meantime, I will try to check the port part with magnifier to see if I get some clues and heat it up.
Thanks for your reply at least knowing I am not alone makes me feel a bit better or worst I dont know right now. :crying:

This one is my firmware

Do you think it is a firmware problem? Then what is firmware that don't have this charging problem? That would be as easy as installing new firmware.

I start to believe it is the motherboard because if it was the charging port it would have worked just by changing the USB port board. I will try to put the original charging board in the oven to see if that works but it looks to me like a motherboard issue.
Thanks for the reply.:good:

i found out it wasnt the usb port the problem since even the jack port stop workig when the issue occurs , dont go higher temps or components could start to melts.

how do you lay it down? USB port touching the ground or like in the picture you upload?

i put mine on a metal cooking plate , also put something in the jack port like an old broken jack so the port keep his form even if heated too much.
tell me how is it going for you

As you can see, everybody is having this problem with this phone , because who hasn't used an after market charger/cord before.
After looking carefully about how people approached this, I am trying a method that I thought of on my own, to try and resolve the issue with the solder not contacting well enough for the phone to charge and possibly having some moisture in there as well.
This is a gentle method and I will report success if it prevails of course!
First take all protectors off the phone. Remove some/memory card. Place phone in a bag of rice so that the screen faces up with little rice on the surface. Aquire a magic bean bag from the local pharmacy, and heat it for 2min and 30 seconds. Place it on top of the phone /rice mixture. Set a timer for 12 minutes. Half way through heat the magic bag for another 1min. Place on too for the remainder of the 12min.
Once done. Keep phone stored in the rice for 2 days in a dry, cool room.
I will be reporting whether this is a simple back/fix for this terrible problem with these phones. Thanks !

Hi, I think I have the same issue you are describing.
My A70 refused to charge early January, would also no longer connect via ADB, but would connect via Mobile Odin.
I returned it, and they repaired it by changing the charging circuit. About 1 month later it happened again. But this time It started working again after about 1 day.
After complaining with my supplier, I got the response that is must be fine since it started charging again.
2 weeks ago, again. After it discharged it started charging again after about a day.
Now last week ago, 4th time, and no luck getting it to charge this time.
Again Mobile Odin sees the phone, and could even flash a new Rom.
But No joy charging.
Supplier accuses me of using aftermarket chargers, and that it's my fault. Does not want to extend warranty "again".

i dont have that problem i bought a wireless charger stand it fits on back hidden by case and it works great i wonder if your phone might charge that way
