Hey guys and gals
this is my first post here. although a lot here is about rooted devices with custom ROMs, I hope you can help me out - you sure have a lot of expertise here compared to many other forums.
For the past two days I've been running into some of the weirdest problems with my Galaxy S2. Before i go into detail, here is the summary:
1. Screen time-out doesn't work while device is not plugged to a charger or computer
2. Notification shows 100% charge for a very long time (hours after heavy usage)
3. Not sure if charging actually works
4. Booting up seems to fail when not connected to a charger
it started yesterday when I noticed the phone light up and say it was charging. The problem is it wasn't - it was in my pocket.
Then I noticed that the screen didn't time out. I changed the setting, nothing - it remained on. I could push the power to make the screen turn off and on again but it wouldn't time out itself.
The charging info went away... at some point. I left it to charge over night and in the morning it indeed showed 100% in the notification bar. The problem is it remained 100% for A LONG time. In the settings menu under the battery it says it has been running on batter for 0 secs and showed 100% charge. For hours... There were no info about any apps or function using the battery. that part was clear.
Then i discovered that the screen time out problem goes away while connecting the charger or via USB to a PC. Then it times out. As soon as i unplug the charger it never times out....
I'm actually not sure if the charging works. Indeed it shows charging but sometimes it magically reaches 100% rather quickly.
Because I suspected a battery fault I used another battery. let it drain completely and then tried to recharge. Can't - when booting it shows a battery icon with question mark and then goes to show that the battery is 100% charged. Then the question mark and then 100% again. Seems to be in some sort of loop.
I've done the factory reset, I had a new firmware installed via Odin just in case. The problem still remains.
Booting the device seems to be an issue and only work with charger or USB cable attached. Ot it will be in that "what battery" and "100% charge" cycle...
I've searched high and low today but couldn't find anyone with the same problem.
Have any of you an idea? Really down't want to get a new phone! Seems to be a very bad month going on because a few weeks ago I had really serious issues with my brand new hybrid camera which i have to buy ... again! sold it for parts for pocket money....
Any help would be really appreciated! thanks!
That's really strange....try getting out the battery,charge it to max va an external charger,or borrow a friend's Galaxy S2.Leave the phone withou battery for an hour.Then when you put it in,go to recovery,and "wipe battery stats"(Root it if it's not).See if that works.

How long have you had the phone? The usb flex cable has issues over time. A symptom of this is the charging when not connected to the charger.
If it is this issue the part is cheap (around 5$ I believe).
Hey Folks,
I have a Samsung Galaxy SII (SGH-i777) that I used a couple of years ago. It was my first Android phone and I loved it very much (until corporate made me an iSheep).
The phone was retired to a shoe box for the last 1+ years and I recently dug it up so I could get it set up for my little bro who somehow recently fell on his phone with it in his pocket and shattered the screen (don't ask... I don't get it either).
Anyways long story short -- the phone sat idle for a long time, when I pulled it out it wouldn't boot up at all. Assumed that the battery had discharged so I plugged it in to see if it would start up. The battery logo would intermittently flash on the screen and show a drained battery logo but even letting the phone sit for a day did not provide me any results.
Fast forward 3-6 months. Today I replaced the charging board thinking that there was some issue with the USB connector on the phone that was preventing it from getting power. Once that was done I discovered that I was able to get the phone to boot into Odin mode. Great! No boot, no recovery, but download mode seemed to be better than nothing.
I have tried, in vain, to flash stock firmware to this phone via Odin, and even though all indicators point to it being successful, once I finish the Samsung logo comes up on the screen, goes off and that's it. I can see the 4 LEDs on the buttons at the bottom of the phone flash every 5 seconds as well as a faint flicker on the screen staggered between the LED flashes.
Looking for any further suggestions as to what I may be able to try. I have searched various sources on XDA and other sources but I haven't quite found anything that matches my exact symptoms.
Furthermore, I can't be sure what Kernel/ROM I was last running on this phone. Maybe Siyah kernel, maybe CM 10,1 with Flux kernel. Idk.
Any input is appreciated!
Seems I should mention this other detail --
With the battery in, I cannot get into download mode -- it just states 'Low Battery!! Can't Download!!" This is presumably due to the fact that the battery is completely discharged -- maybe incapable of holding a charge but perhaps this is indicative of a more serious hardware failure.
I'd guess the battery is completely shot.
I bought a replacement battery from here: http://www.ebay.com/itm/111014533334?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
No problems with it.

Very likely --
Since you got me to shift focus here, a quick search is telling me that it won't boot without a battery due to a feedback circuit. This would explain the ability to go into download mode but the lack of boot / flashing LEDs I guess.
Can someone confirm?
If the phone was working normally when it was put away, I would expect it to be working normally when it was pulled it back out. Your story is a little confusing, but did you ever try booting the phone with a fully charged battery? In the circumstances you describe, that would be the first logical trouble shooting step. And if you haven't tried that, then it is still the next logical trouble shooting step. Also, you can't assume that the original battery that you left in the phone is still able to hold a charge. It still may be good, but you can't assume that for testing purposes. Incidentally, the battery should have been pulled from the phone before it was put away.
I do not get any indication that the original battery is actually charging. Charging icon just flashes on the screen briefly in between LED and screen flashes (again, presumably due to the battery being completely dead/incapable of holding a charge since I left it in the phone this entire time).
I guess I'll go ahead and buy another battery and see what happens.
It is my understanding then that this phone will not boot on the charger without battery due to a feedback circuit. Correct?

Even if the battery is good, but fully discharged, it may not charge in the phone. You would have to have an external charger. Phones are not consistent, and many phones probably would charge a fully discharged battery, but I have seen a number of people report that a fully discharged battery would cause the exact same behavior as you report. If it were mine, I wouldn't throw the battery away yet.
If you know anyone with an I777, you could borrow their fully charged battery for a few minutes just to see if your phone will boot.
You are correct that the phone will not boot on the charger when the battery is out, although you should be able to successfully flash firmware through Odin with the battery out, and the computer supplying the power, but still, as far as I know, it will not boot after the flash without a working battery.
The battery was indeed at fault. Ordered a new one on Amazon, popped it in and voila -- we're up and running.
Thanks for the input guys! Much appreciated!
My phone is having issues charging even with three different cables. If I plug the phone in while it is off, it turns on and says it's charging. But it doesn't receive a charge. If the phone is on and I plug it in, it says it's charging on the lock screen, but the icon doesn't change to the charging symbol and it doesn't receive a charge. I have tried wiggle the cable a bit while it's plugged in, but that doesn't help. It doesn't seem like others are having this same issue either. Am I screwed? I also unlocked my phone. Does that mean I am double screw and Huawei won't help me?

Hey all, here is a quick update. I spoke with a gentle from Huawei and was suppose to get a replacement sent out. However, I believe I was under volt charging the device and that's why I got those strange issues. It recharges every time from my car and my computer, but not from my wall. Kimtyson, Huawei said the exact same thing as you. Good call!
With the phone running, go to Phone Manager and then go to Power Saving and then Consumption Level. Is Cell Standby draining your battery? It is on mine.

For me, it's only 2.94%. I have to say though, going from 4.3 to 5.1 was a huge difference in life battery. For the worse. I went from one charge every 3 to 4 days to once a day.
However, I believe the USB port might be broken. I don't know why though. I haven't been rough it or charged it at a angle that would put extra pressure on it.
It might be worth doing a factory reset and\or reinstalling. Could be a bad flash or something. Also, try returning to JB. Just make a TWRP backup or something so you can get back to where you are now. See if everything is working back in JB. If so, it's not the USB port.
Dear all,
I hope there is someone here, who can help me with my issue. I lost my hope after trying almost everything found in the internet.
So here is the problem: I was using my phone as a navigation in my car. The battery was low, so I used the car charger and kept it plugged, while driving. I observed, that even though I was charging my phone via car charger, the battery continued to get low and finally the phone turned off. After reaching home, I plugged my phone with an original quick charger from Xiaomi. Unfortunately I was not able to charge my phone and it got stuck in a bootloop, with a phone showing Mi Logo, vibrating and switching off repeatedly.
When I connect the phone with the laptop, it is shortly recognized (when it is booting) and then disconnected and again and again. I can go to fastboot mode but I cannot flash my phone using MiFlash, because I get an error: Failed. Low battery.
Does anyone know the solution? I would really appreciate any help.

Are you on miui or a custom rom?
I think I know what problem you are facing, your device's battery is actually drained of all the power, like it empty. So drained that it doesn't even have the energy to turn on the phone to get power. I had a lenovo a560 last year, and it had the same problem, so what i had to do was either leave it for charging and pray that it begins charging (and sometimes after 3 or 4 hours the battery started charging as normal when it got 1% battery), or the second method was that i took the removable battery out and charged it externally using wires. The second method worked since the battery got enough power, to keep the phone on during charging.
Now the problem is that redmi note 4 doesn't have a removable battery, so either you can leave the phone for charging, and actually forget about it for a day, or the only other thing is that you have to visit a service center.
Not joking about the charging process but that is the only thing you can do.

But wait, if the phone is able to stay in fastboot mode, why not charge it there? Like just open fastboot mode, and connect the charger. It will atleast charge some percent.

Hi, i thought about it before, but the phone was staying in fastboot mode for a very short time, to short to charge any resonable amount of power, and kept rebooting quickly. I left the phone for two days without trying to fix it and I tried just now to go into fastboot and try to charge. It stays now for quite a time in fastboot so I will keep my fingers crossed that I will be able to charge. I will update here if it was a success or not. Meanwhile, thank you for all your ideas! Lets see what happens...

Unfortunately, no good results. I kept my phone in fastboot mode multiple times, but I was not able to charge my phone. Turning off fastboot is only causing phone to stuck in bootloop.
I also had an impression, that the phone was not warm at the back, where the battery is. Now I am starting to think that the battery is completely dead and I have to change it. But how is it even possible, that after 8 MONTHS the battery is completely f***ed up?
Can I somehow check the state of the battery? I would like to be sure, that there is no way to bring the battery back to life and I really have to go somewhere to change it. I am really reluctant to have a battery from some unknown company. :crying:

Are you rooted?
This is really a kernel fault man, I had the same issues with mediatek Chipsets before, but you are saying in "8 months", so that means you are well covered in warranty. You can send an e-mail to Xiaomi customer care or visit a service centre with the phone bill. I am pretty sure a faulty battery or such happening can be covered using warranty, plus I would suggest NOT to get the battery changed from a 3rd party store.

Sorry, I actually don't know much about the phones, so I don't know what 'rooted' means. I never did anything with my phone, software or whatever more than required.
With the warranty there is a different problem in my case: I bought my phone in China when I was there for my business trip and I live in Europe (yeah I know, my own fault, I should have bought it at home). I have bill and everything but I guess it will not help. Besides, Xiaomi gives 6 months warranty for battery (in case this is really the battery).

Knowing that you are not rooted is a positive thing when regarding the warranty, ok so here is the thing which you should do. But first of all please stop the battery charging process, since this can now be harmful and can damage the components. Ok so here's what you should do -
[email protected]
Send an email to that address regarding the battery problem. And provide the details including about the drainage of battery, and the methods which you tried. Plus attach the bill also. It doesn't really matter where you bought it, because the bill serves as to give them information that the device you own is actually bought by you, and it contains details about device like IMEI etc. If they respond and say that you can send your device to them, (in this case they will give you an address) you should do that. If they say they cannot help it, then consider getting a repair from a local shop.
I just checked my phone's inside and found out that you cannot externally charge the battery, so this means you need a repair, unfortunately.
Before ending this reply I just wanna clear the fact that,
The battery isn't damaged, it just isn't able to get power,(here it is because of the device) this means that if somehow some energy can be provided to the battery, the battery need not be replaced.
I wish you luck , may you be able to fix your phone again.

I am still waiting for the response from Global Service. If nothing happens, I will go to local 'mi center', where I know they can repair xiaomi phones, but not on warranty.
Apart from that, phone is still dead, but I have not tried yet anything else. I found this: https://xiaomifirmware.com/guides-and-tips/fix-bootloop-redmi-note-4-mtk/
But I am not sure, if this should work. Anyone have tried?

I did not try anything from this yet, I have my phone at home, but maybe it will help some of you.
btw. the previous method from the link (deep flash mode) is not working for me.
PEOPLE I FIXED MY PHONE!!! I used again and again this method, which I have already posted before: https://xiaomifirmware.com/guides-and-tips/fix-bootloop-redmi-note-4-mtk/
I didn't work at the beginning, so I left my phone and actually wanted to wait till I go back home to my country for the weekend and visit Xiaomi service, but FINALLY IT WORKED!!! I cannot explained what was the reason that this time it clicked. My phone was completely drained, left for long time without touching. As a result I have a battery icon now and it is charging, no bootloop anymore. Hope this method would help someone. Be patient and try multiple times!
So it is not software problem causing the bootloop
So it is not a software, but only hardware - the battery - as the only problem in this case. I am facing a very similar case with my Redmi Note 4x Mediatek (4/64 Memory) just starting Friday morning (9Feb). I thought it was charging overnight, but in the morning found the power totally drained, and stucked not be able to recharge for hours. This phone is still under warranty (9month use) but ridiculously the Official Service Agent said they need up to 40days to fix this phone. This is worst experience comparing to other phones I ever had.
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.
