Doesn't recognize the battery 0% - Xiaomi Mi A2 Lite Questions & Answers

Hello everyone,
I have a problem and it is that my phone does not recognize the battery stays at 0%. When I connect it via cable with the disconnected battery it starts up and on the home screen I have to connect and disconnect the battery quickly for continues the start up. Once started, it dials 100% because it has the cable connected and when I connect the battery the phone still works but dials 0% and does not charge.
Once the mobile is switched on I have set the development options, I have set the USB debuggin, I have unlocked the bootloader and have I stalled a stock ROM vía Mi Flash.
All this has been made perfect but to start the mobile I have to perform the same operation that I explained at the beginning and still marking 0% battery.
The truth is that this is crazy, what do you think it can be, a failure on the motherboard?
Do you recommend that try something else? Thank you very much in advance.
Regards.

Tried replacing battery on it? I think battery failing than motherboard.

Sorry. I didn't say that the first thing I did was change the battery and keep doing the same.

I better look at an electronic forum, right?

Touch Pro2 battery doesn't charge

Hi,
My Touch Pro2 is connected to AC adapter for many hours and led is on (red), but the battery indicator doesn't increase or decrease, it's always %80, I tried to charge it while it's turned off, and I tried to charge through USB, but problem persists.
I own this device for 9 months.
What's wrong?
Please help.
Thanks
It may be worth it to try the battery calibration method described here. even though it is for android, it's worth a shot. I know it wont pass the first step, but maybe somewhere in there it will kick in.
It's also worth powering off, taking out the battery, hitting the power button a few times, then put the battery back in, power on, then try to charge. If that doesn't work, repeat the previous but try to charge without turning back on.
If all else fails, it may be time to try a new battery, or a warranty exchange. I think you have a year to do that as long as it was not purchased as a refurbished model.
good luck!

Thanks for replying.
I tried to power off, take out the battery, hit the power button a few times, but didn't fix the issue.
I've been using my device without charging for the whole day and battery is always 80%, never decrease.
I'm trying to use my device until the battery is totally empty, then charge it.
Sorry that didn't work for you. I just noticed the intended link for the battery calibration didn't make it to the post. Don't know if I forgot, or it just got stripped b/c I miss-formatted the hyperlink. But here it is if you want to try it (assuming your depletion experiment doesn't work):

This was different from my second recommendation that you already tried...
Also, have you installed any battery drivers (such as the 1% one?) Could be a corrupted driver that needs to be replaced.
I formatted my device, nothing changed.
The recommendation mentioned in the link says that I allow the phone to charge until the notification LED is green, but the LED can't turn into green because the battery indicator is always %80, and doesn't increase at all.
LED is turned into green when the indicator is %100.

Yah, I was thinking it might work if you skip that step and move on to the next part. Granted, I'm just shooting in the dark here. The fact that it is not changing at all (up or down) seems to indicate it is a software/hardware issue rather than the battery anyway. Maybe someone else where have some better ideas...

try to install a new battery driver or reinstall the one ur using if you are using a cooked one such as the 1% driver
one more suggestion: have you tried charging it while its turned off?

Hi,
Any problem with the mini usb port? I had a similar problem and had the port replaced by Dr. Cellphone. now it works perfectly.

It's unlikely, but still possible the driver for the battery was corrupted in a way that even hard reseting does not fix it. Its worth it to try a new driver even though you have not messed with the one that came with it. (not like it can get any worse, right?) You can find the 1% battery driver at the top of the rhodium general subforum.

TP2 won't boot or charge either!!

Hey guys, I got a real big problem.
I've got a Rhodium100, but it won't charge nor it'll boot.
When connected to original charger or pc the phone starts. Then I can see the HTC logo and it dies again. The battery seems to be totally dead
What I've triend so far:
1. Pulled out the battery
2. Multiple cabels for the charger
3. Soft reset
4. Hard reset (won't complete because the battery is dead)
5. Checked the on/off button (on top)
What else can I do to fix this problem? I'd like to try anything before sending the phone to HTC (did that 2 times before, but with other problems).
This is what happens: MOVIE
Thanks in advance

Buy a new battery and see if that helps. There are some cheap ones on ebay.
I just found another cable and it seems to be he's charging again. But after 5 hours of charging it's still on 40%.
When the battery-level is around 45% it goes downwards to around 38% and then to 45 again..
This is circulating..
How can this be?
You shouldn't let the battery completely die in the first place. A deep discharge of any Lithium Ion battery is not recommended because of this. If you've tried to do a hard reset and it did not complete, you may have destroyed the ROM image. If it doesn't turn back on, flash a stock ROM.
Always try to charge the device before it gets to 5% remaining battery. 10% is recommended, but 5% is the lowest the battery should ever be. Having a second battery is always a good idea. I have two of them and an external battery charger. This way, I can always have a battery able to charge without needing the device just in case something goes awry.
Make sure you do not turn the device on. Leave the battery in the device overnight on the charger without turning it on. If it still does not function after this, you might try purchasing another battery and charger.
If you have time left on your warranty, this is covered by it. Simply call your carrier or HTC and they will fix it for you. It's generally faster to go through your carrier if you have the option to do so.
Thanks for the tips. I followed them and it seems to be my phone is fully working again!

I have the same problem since august 2010. I've do the same as you flashing some ROM's also restoring original one(T-Mobile), buying new akku ang external charger- but nothing helps When I place battery in phone it switches on by self(seems like power button abridget but I've checked it with testing device), starting showing T-Mobile logo "Stick together" then shows windows logo then backlight fading then device restarts, so it happen infinite till battery fully goes empty. Now on phone is installed original ROM and I can't install any other- in bootloader I can install only SPL's, but other ROM's not installs (flashing process freezes on 0%). I haven't any ideas, somebody can help me? Thank you all.

It's a dead battery. If it powers on by itself, then you'll either want to get a new battery or an external battery charger. Make sure you're charging from the wall, and not a USB port.

Yes, I do as you suggest - bought new battery and wall charger, but no result. I doubt that new battery or charger is destroyed, but anything is possible... What actually kind of problem if phone couldn't do hard reset, not upgding ROM, also switches on when battery is placed into? 100% fault (discharged) battery?

I mentioned that you may need to charge the battery externally if it is powering on when you insert the battery. You'll either need a friend's phone to charge it, or buy an external charger. With the external charger, let it sit on the charger overnight, pop it in the phone, and then try again. If using an external charger does not work, then you may want to send the device in for repairs/replacement.

[Q] Charging Problems with GN I9250-XXLFA

Hello,
I bought a GN, I9250, European model, made in China 4 days back from a vendor online.
I am having problems charging the phone.
When PHONE is ON
1. When plugged into the included charger/cable, the battery status shows CHARGING (AC) for a few minutes and then changed to NOT CHARGING. Removing the USB plug or switching off the mains and restarting in a minute takes the status back to CHARGING (AC) but again for a few minutes.
2. Tried with multiple chargers and cables with exactly the same results
3. When the phone is connected to USB port in laptop, the charging happens, for a longer duration. The laptop also detects the phone immediately and I can access files etc. After say 20-30 minutes odd the status again goes to NOT CHARGING. However, while the phone is not charging, I can still access files on the phone. This implies the USB connectivity is still perfect, only the charging has stopped.
4. Under no circumstances does the charge go beyond 50% odd, irrespective of the duration of charging
When PHONE is OFF
1. The phone shows the battery icon with bolt for a few seconds and then shuts off. If I click the power button briefly I can see the battery charging icon.
2. I kept the phone in charging with the wall adapter all night, and got 49% charge only, starting from about 10% when put to charge.
The battery indicator graph shows the phone is has never hit a charge level above 65% types.
I have not seen the other charging issue of the phone showing a bolt in the battery icon even if the phone is not plugged in ! (thank god!!!)
I bought it "as new" condition, and performed a factory reset immediately on receiving the phone. So its running stock applications, with almost everything except voice and 2g data on. No applications except Whatsapp are running.
All other aspects of functionality are working well.
I have read hundreds of posts across the web and am not sure what the problem could be with my phone. I am in India and since the phone was bought off the net, its unlikely that it will be provided warranty etc here. In fact I'm not even sure if there will be servicing competency in the technicians here.
I have tried to puch the micro USB tongue by pushing it upwards gently, but cannot really say whether or not it did bend or i was just too fearful. Have tried removing battery etc and all other soft methods written everywhere.
Any help ???

Hello,
I do suspect it myself, but I don't know how to verify this. Can any other Samsung phone battery be put in the phone or is the phone compatible only with this one? Getting another battery is not possible in the near future since this is not available in India...
Any thoughts on how to check this?

I have the same problem, but it's not the battery's fault. My brother also has a GNex, and I tried charging my phone with his battery, and vice-versa, without any luck. I think it's the USB port's fault. Something about power not getting to the phone correctly. Luckily I bought it at a store here. I talked to the owner, and I'm going to exchange it for a new one tomorrow.

Hello,
I found another GN and did this experiment.
1. When I plugged in my battery which was showing 53% on my phone into the other phone it showed 79%.
2. When I charged the other GN with my battery inside, it charged to 100%
3. When I put my battery back into my phone, it showed 67%
4. When I put in the other GN battery into my phone it showed 49%, while it was showing 82% in the other GN.
5. I was able to charge this other battery in my phone to 60%.
6. When I put it back into the other GN it showed 94% charge.
Apparently my battery seems to be ok. Also, it seems that my phone is charging ok too. But there may be a problem with the phone detecting the battery level !!
Any thoughts?
Hello,
i have exact the same problem. I tried 3 batteries a lot of chargers and i changed the Charging Port Flex Cable.
This all without success
The Problem is, sometimes it charge to 50%, the most it charge to 75% and one time i get it to 81% yeah
So does it give any help for this Problem ?

[Q] Stock OneX switched itself off, now red flashing light.

I have used the search button and found many people with similar problems but I don't think any of them are the same as mine hence the question.
Please be patient with me as I'm new. :good:
My 18 month old factory stock OneX was switched off and on charge over night and in the morning the green light was on.
I took the phone off charge and switched it on, all was fine and I put it in my pocket and drove to work.
After about 5 mins I hear the low battery chime from the phone and when I take it from my pocket it has switched off and will not switch back on. I plug it in to a charger and get a red flashing light. I've searched for days and tried all the button pressing tricks, charging from mains, charging from usb and nothing has brought it back to life.
Thinking the battery had just decided it no longer wanted to be part of this world I bought a OneX+ battery and changed it over, it is still the same.
If I hold down the volume - and power buttons it will boot to the screen where it tells you it is ***locked*** and tell me not enough power to flash.
If I plug it in to the pc the HTC MTP device loads every few seconds.
Is my phone now an expensive paperweight or can it still be revived? Any help greatly appreciated.

What I understand you can go in bootloader this is ok! But it is strange that HTC MTP device loads every few seconds. Are you able to start the Android? Becouse only if you start the system you can see the MTP device in bootloader it is inposible.
Second download this unzip to folder and start the file chargeONEX.bat report back if the battery start charge. Dont worry the phone will start a lot of restart in the bootloader but will slowly charge.

I can only get in to the bootloader when connected to the mains charger, it will not go in to bootloader when connected to the laptop usb port.
I will try on a desktop pc and see what that does.
I ran the .bat file and it gave me a voltage of 477mV, this is a brand new OneX+ battery, I did try this script before I changed the battery and the old one was 536mV
Because the phone will not boot in to bootloader when plugged in to the laptop it only runs once, then the screen goes black, it is then that the MTP device loads every few seconds.

Just you buy your new battery empty this is bad luck for you.
in my zip have fastboot-mac rename it to fastboot and the fastboot rename to fastboot-windows. Are you manage to start in bootloader. Are you with custom recovery. If you are with custom recovery go in recovery and try to charge the phone in recovery.
EDIT: I see you are full stock will not help with charge in recovery.
The best way will be if you start the script to charege the phone but if you cant the best way will be to charge the battery manually.

Checked again and the voltage is now 550mV.
At this rate it will take weeks to reach enough charge to switch on.
I'm not sure it will ever get to full charge, I think something else on the phone is causing the issue.

i think not, the system reads the battery voltage and 3680 mV is round about 10% of charge so 550 is way undervolted. and if i am not mistaken 4200 is about full loaded.

at least that's what i read from here

I am not sure the battery is deep discharged but have 50-50% to be good. If you have battery pack but not to connect with usb to the phone The battery pack must use the pins on the back side on your phone try to wake up the battery or manualy disconnect the battery and charge it or the chipest way is to buy new battery but mesure beffore to buy.
The battery voltage is slowly rising and is now at 562mV.
I'm still not sure this reading is correct because when you start in to fastboot or recovery you can remove the charger and the phone continues to run. Surely the phone would switch off as soon as the charger was removed if the battery was as low as .5V
Any ideas?

well it may be a bit more difficult but i would look for a way to charge the battery from another source outside the phone. something like a little project of cutting wires and connect them straight to the end of the usb cable (wall charger) ...... welll something like that ?

I'll give it a go, nothing to loose.
This is a new battery I've got in the phone now, the original one read the same voltage. Only thing I didn't do was to check the voltage of the new battery before I installed it.
I'll try charging the original battery that is sat on my desk.

I've just checked the voltage of the orignal battery that I removed from the phone fully charged and it reads 4.2V, my multi meter might not be 100% acurate as it's only a cheap one. I also checked my 65% charge HTC Desire battery and that reads 3.9V.
So it looks like the batteries are fine and the phone is seeing the wrong voltage.
Do you think this would definitely be a hardware issue?
I cant say no but indeed those voltages looks fine. It could be the circuit on the mainboard not reading correct

[Q]SM-T211 battery drain problems

Hello,
I have a problem with this tablet , when i charge it to 100% and use it for like 5-10mins i'm suddenly at 1% battery. But i can still use youtube or other apps for 40mins + So i'm pretty sure the battery is at 95% or something.
Also when i charge and stop charging it can reset the whole thing and say that i have 2% battery.
I already tried to charge 100% > let it decharge 40-50% > power off 5houres > but didn't help..
Somebody said remove the battery for 5mins and problem is gone..
Anyone done this so far?
i'm on STOCK ROM , no root or what so ever.. NO battery save app or something like that.
Hi, I'm having the same issue but it's not as dire as yours. Since you're not rooted or anything, I strongly believe it's a hardware issue, try replacing your device cause it shouldn't drain that fast. I'm using nolekat rom and it takes me 10 hours to charge fully or more but half the time for it to be drained. I haven't tried removing my battery manually but you could try that too. Most likely it's a hardware issue since you didn't mess with it so much. Hope this helps.

Hi,
My tab is getting switched off frequently though the battery is fully charged, it suddenly dies down during any kind of work and im not having battery draining problem in my tab. But when I plug in a charger or battery bank then the tab works fine with out shut downing. Is this problem related to battery or hardwire or software. Kindly suggest if some one facing similar situation
Hi XDA
I have another problem, not too bad as yours, but very nagging and upsetting. What happens is that my tabet takes practically half a day for charging up the battery. It takes like 12 or more hours to charge up from 0 to 100%. I have tried unplugging the battery as you explained many times, also draining it, but nthing changes. And even worse it is when I'm just plugging my device after totally drained the battery, so when I try to boot my device it may boot up, when it does, after one minute it's turning off because of a suposedly 0% battery. Really I might get either that 0% or 1% battery, but after a minute when I just plug it in and boot up, it may turn off even though I turned off the sceen inmediately.
I think. the problen is maybe on the battery or in the USB port, I have tested many USB cables, many chargers, charging from my PC, but the problem keeps going an and on and on. I would like to know why this problems is happening, if I could fix it up by myself, for instance by replacing the battery or the USB port. This device was a gift, and since I got it I was dithering whether it was normal or not, but by asking soome mates and reading your post I realize that this is not normal.
Hope you read this quick reply. Many thanks for your advice and giving me advice on what and how I should do...

Changing the USB flex cable worked for me, try to buy one and watch some good tutorial about how to replace your tablet's components.
