Since I changed the screen of my Mido, the red led is blinking when I try to charge, before that I unfortunately left the battery fully drain.
When I disconnected the battery and plugged the phone at the charger, I had the MI logo and was able to access the FastBoot. So I flashed the last official rom.
Now, with the phone plugged and the battery disconnected, I can successfully boot to system. Everything works normal, but the battery level indicates 50% of charge.
Sometimes the phone don't boot, and shows the big battery level at 50% and the green light and shows a constant green led, so i need to enter in recovery mode to boot the system again.
If I connect the battery with the system on, the battery level goes to zero and in a few seconds the phone turn off and the red led blinking returns.
Should I buy a new battery? Any other ideas to try?
Thx in adavnce!!
It is strange that everything happens when switching screens. Are the cables properly connected to the board? Any screw that makes a short? Any damaged cables?
My experience when changing a battery is as follows (I continue with the same in this example). I changed the betreia thinking that it would improve the life of the battery (the old one was inflated but it reached 100%) once I put the new one, the charge does not exceed 94%, even if I charge it. Something curious is that when you disconnect and connect the cable ... it charges automatically in seconds to 100%, it seems to be going well, right? no, since once removed from the electrical current the battery drops quite quickly to 71%, whatever the use you give it (games, social networks ...) there it stabilizes but still is not a good experience. It is not the rom as I have changed many roms (unofficial official, linegeos, pixel experience ...) and it remains the same (still need to test stock) (original battery).
With this I am not saying not to fix it by changing it but ... this can also happen to you.
I am still waiting for help me with that problem.
I hope your problem is solved soon.
Just to give the case a conclusion, I ordered a new battery and everithig is fine now!
Thx

Hey...
My Mozart seems to have stopped working. The battery run out this morning when I was in university and ive just got home and plugged it in to find that the red led is flashing up the top! Its flashes for a while and HTC comes onto the screen, it then shows an image of a battery on the screen then nothing, no lights, no charging, no booting.
Help!
i see well that happened to me, you seem to have drained the battery. the best solution is..
keep it charged for a while..
if it does not work.. remove the battery for a while then bring it back and charge again,
just let it charge until the battery regains enough power to boot the phone.
never let the battery fully down /!\
the smartphone Have to be charged before the battery nearly 30% otherwise u Will deteriorate the lifetime of u'r battery
Hi, I would like to know if the problem was the battery or hardware related? I am having this same problem and Im about to go to the phone shop to get this looked at... after being on the phone to someone who speaks the worst broken english for 20 minutes!
Thanks.
The first time I've allowed my battery to get very low since installing CM7 on my HTC Merge and I'm now having all sorts of problems.
Firstly my screen won't light up. It's just completely black. The phone is on and the 4 buttons at the bottom light up but that's all. The phone is still responding to my touch as I can load apps and hear noises if I happen to touch the correct parts of the screen. It's almost as if the brightness has been turned way down, but I'm unable to see the controls to try turning it up again. I have tried booting to recovery mode but that doesn't display either.
Secondly the battery won't charge. Since the battery is drained I can only get the phone on when it is plugged in, but the orange "charging" led at the top of the phone never lights up. It just casually flashes like it ordinarily would have done when it was running from the battery. I have two batteries and they're both doing this.
I can't be 100% sure that these problems are due to the installation of CM7 but I've never experienced it before so i'm guessing they're connected.
Does anybody have any suggestions on how I can get my phone working again.
It's also worth mentioning that it is also no longer recognised by my computer
Sounds like a hardware fault, if you have the same issues in recovery as you do in your os then its very unlikely its ROM/software related
I don't your device nor have I taken it apart so its only guesses I could give you on which component needs to be replaced, LCD or flex cable are best guesses

Want to update on this as I've just had another look at it after a while.
With the battery having completely drained, I connected the phone to charge via my PC and the orange charge light lit up and the phone went into recovery mode without any assistance from me. After about 2 seconds the screen went off again.
When the battery has charged sufficiently, I am once again able to turn the phone on and it boots up... but the screen remains blank.
If I discharge the battery and then plug it into my PC, I am able to repeat the appearance of the recovery screen, but it always vanishes before I am able to do anything.
The screen must be surely be functional or how would I get those 2 seconds of display ?
Does anybody have any ideas of what I can do to get the phone working again?
I acquired a new battery and after fitting it the phone immediately worked again. The battery was completely without charge but the phone charged it up without any problems. However, as soon as the power ran low the same thing happened; the screen has stopped working and the battery doesn't seem to charge anymore.
So I got my MX4 yesterday, opened it like a kid at Christmas. But weirdly the battery won't charge while the phone is turned on.
I left it overnight plugged in to a good charger and turned on, and it didn't even raise 1%. But when I turn it off and connect to a charger it charges with no issues.
I suspect this isn't hardware related due to the fact that it charges fine when turned off.
Anyone have any ideas?
In my case, it was a software problem that has been since fixed with OTA-5.
The battery percentage displayed used to be on the fritz but it's all good now so look for that system update in the settings and let us know if the issue remains
Thanks for the reply!
It's not just a battery % issue though, because it's actually not charging when it's turned on. Like I said if I turn it off and charge it it charges like normal and it starts from the % it was saying it was in the OS.
I do have OTA 5, but I think I might try flashing to Devel and back, or resetting the phone.
Thanks,
For me, I wouldn't see a difference in percentage until I rebooted the device :/
Don't hesitate to contact Meizu's customer service depending on the outcome
I recently picked up this galaxy s6 edge from a friend that upgraded to a new phone. It won't turn on, neither to android recovery, nor to download mode nor the android. I charged it via wireless charging overnight and i tried for around an hour with a usb cable. What do i do?
same issue i am facing, i tried original charger, wireless charger and fast chargers from many different brands. but all failed. The device only gets warm/hot while charging and nothing happens. neither download mode nor recovery mode works. I am kind pf stuck without any solution, my device was used very rarely and its like an brand new device. Doesn't know what to do, if you find any solution then please let me know too. thanks in advance
Same problem. If I press power button very long, blue light comes on. Then it's stuck and stays like this until battery is flat. Battery charging is not possible: device heats up (tried USB and Qi), but battery doesn't take any charge.
So I opened the S6 and checked the battery directly. I can charge it directly with a lab power supply and when I plug it in and press power button, the blue notification light comes on again until battery is empty again. I can also see that only ICs get hot, but not the battery when plugging in USB.
So, it's definitely some hardware fault. I suspect power IC that is not able to power up the screen. But I don't know. I will investigate further but it looks difficult. However, I have seen many YouTube videos with same symptoms, but problem was always different than mine :/
Hi guys,
This thread is 2 months old, any of you managed to fix the problem?
I am having very similar problem. My phone was on a shelf for about a year and a half. Before now it was working perfectly. Now I can't charge it via USB or power adapter. When trying to power it up or get into download or recovery mode, nothing happens. Computer does not see it. Tried different cables, USB ports, power adapters..nothing.
The only thing that is happening to the phone is the battery logo appears when trying to charge it, though the green bar does not go over battery, only the empty grey battery with lightning icon in the middle. Also the screen does not go dark after a few seconds as it should and the red/blue LED does not turn on.
Is this the signal from the phone, that the battery is to deeply dischareged and cannot be charged again? I am googling all over the web and can't find anybody talking about what phone does in case of to low voltage on battery.
PS back does not seem to be bloated, USB port was working perfectly last time used
Please try to help, you are my last stop before opening the phone and start probing the poop out of motherboard to see what gave.
EDIT: something interesting happened just about an hour after my post. The battery suddenly started showing % of charge and the green bar started running, computer recognized the phone.. as everything should be.
My FIX: leave the phone pluged in and charging for about 3days and it will start working again.
My semi professional explenation of fix and problem: the phone has a ''backup or reserve'' battery. It is actually main battery but the last I think I read somewhere it is 20% of capacity, is reserved for phone exclusively for the clock and all other electronics that need power when switched off. Now these 20% probably were discharged due to laying around for almost 2 years.
It took me 3 days of charging to fill up these ''20%'' I guess. Probably because Lithium batteries are charged VERY slow at very start and end. This is safty procedure for ALL Li batteries.
If any expert can confirm my conclusion please do so, to help other people.
To answer partialy to my question: The phone tells you battery is ''deep'' discharged when you only see the charge icon without the green bar.
In the mean time I was writing this edit I came up to 4% battery and turned it on!

So, I am having some problems to give a second life to this device.
I bought twice a battery to replace. The first one was clearly a second hand battery sold as new, which lasted 6 months, after which, it started to grow bigger in volume and its performance dropped dramatically lasting half an hour working. I tried to get a refund but no luck.
After that experience I tried a second seller who promises nothing less than 2 years warranty for the battery (wow). I bought a new original one and installed it. It seem in mint condition so I thought it would do it.
It worked everything aparently fine. I even installed a new custom room (i must admit that i am not sure if i did it right) But it appartenly worked. I had cRdroid with android 10 running smoothly on the phone. Not sure at this point if I rebooted after that. I think so.
The nightmare started once the battery ran out (I did it on purpose to calibrate de battery). The phone didn't wake up again. I started to have a blinking red notification led. It seemed not to be charging at all and indicating some problem with EDL mode or with very low battery. The fact is after trying long time charging, several chargers and cables, etc, i managed to get a yellow led light.
But what I can get by now is:
-if I plug a charger with a (sometimes) notification of a stuck 50% level of battery (wtf), sometimes bootloop, sometimes black screen
-Entering in fastboot mode with (vol- + power)
-Not able to enter recovery
-If I try to swich on it does not react to power button in any way.
I tried to flash all stock files by using xiaomimitool but it does not boot system afterthat (although i can get to stock recovery once at least after that)
i tried flashing twrp and it says ok installed but I cannot enter afterwards
and so on..
do i throw the phone away?
btw, it is unlocked and it is rn4 global sd version (mido)
I would have checked the battery voltage before flashing anything.
For me, I would have also taken the old, dead battery and used the the BMS PCB and connector off that and a bench power supply to power it up as a check.

Hello (a bit late).
I find this to be something that I should have done more than a solution now the problem is here. Even tough I don't properly understand your proposition and I find I might not possess the tools that you explain.
I never though that replacing a battery would bring this problems.
I managed to bring back to life the battery. Now is working without problems, but only because I am avoiding the phone from completely discharge the battery and I am charging it before it dies. Otherwise I have the feeling that battery will go under voltage again.
Is there something I can do to avoid this? I have checked voltage with some app and lectures seem to be normal while its working: 4.38 v and going down while it discharges. I do not have the old battery.
