What phone is this? This forum is specifically for Redmi 8a so that might be why your phone is messing up

First of all, this forum is for redmi 8a and that phone does not look like redmi 8a. But you might have turned ambient screen always on while charging. Maybe havocOs is not stable or there can be other problem like in charger. So try changing the rom or charger or usb cable.

[Q] My tab can't power on, battery charging also fails

All of a sudden my galaxy tab can't power on. It works ok last time and power off successfully, but today when I try to open it, the splash screen just don't show up. I tried to enter recovery mode, but also failed.
When connect to the cable for battery charging, the screen is as the following, without any motion.

How long has it been since you powered it off? Some of these devices have safeties to prevent power up if it doesn't think it has the juice to boot all the way. How long have you had it on the charger?
I have seen this on my Tab.
When the battery was drained to 0%, and I started charging it. It's like it it need 1-2% before I can boot.
If you can't boot after having charged it for a while, I beleive either your charger is gone, or more likely the battery itself or something regaulating the charge.
Yes, I didn't charge it for a long time when this screen appears, will try and let you know.
WORKS!!! It return to normal after charging for a while. I suspect that for some reason it is not completely shut off last time, so the battery is drained to exhaust. I think Samsung should put this battery indication icon to their user manual to avoid confusion.

i9100 starts charging even when disconnected, random reboots

Well, as the title says I have a Galaxy S II i9100 (Int'l Exynos Version) that thinks that it's charging even when its disconnected from the charger. It also heats up sometimes. When I connect it to the charger I never know if it's actually charging or not. the battery level indicator itself is problematic. For example, if it shows 90% battery level, when i reboot the phone it'll be at 70%.
Phone: GT-i9100 Exynos
Battery: Stock 3.7 V li-ion 6.11 Wh
OS: Android 4.2.2
Root: Yes
CM version: 10.1 Nightly (2013-04-23)
Kernel: 3.0.31 CM [email protected] #1
Thanks in advance!
Try dif nightly or clean usb port. Battery drop after reboot...dose it go Bk to right% after a while or drops and stays dropped?

Tried diff nightlies, no idea how to clean usb port(it connects to pc/probably charges, so i think the port's ok)
As far as the batt level goes, it sometimes begins to rise without charging
With 100% alcohol and ear bud. Be. Careful and make sure its powered off. Better still take battery out before you do it. If its rising after its ok. Reboot will cause battery to drop them go Bk up. Have you tried a different battery to see if yours is faulty?
Earbuds won't fit. Too big, port too small
Something sim would do. You get the idea
i cleaned it with a dry mini-brush thing, still problematic. Also, i found out that if i connect the charger without the battery inserted, phone shows charging animation.
Pass mate sorry
Happened to me to. I got a new USB port on ebay real cheap.

Easy to change.
flashed Samsung stock ROM(I9100XWLSW_I9100XXMS2_I9100XEULS5_HOME.tar) now. No difference. Hoping it isnt a hardware issue because I'm out of warranty and probably will sell this later for something newer so trying to avoid spending much to repair this.

S2 results always active while charging

Hi, I know there are already many threads about it but I think I have a slightly different problem: while charging the phone is always active (as if he was doing something in the background) resulting in an extended charge time.
First thought: there must be an active process (developers opts-> show cpu usage) and ... nothing
Second thought: maybe "dmesg" can tell me something more and...
...well, that seems something

The "adc" value of the battery significantly increases when connected to the wall charger, so even if the "adc_chg" value is high it is compensated by the high drain of the battery.
Am i wrong? Has someone any idea about the cause of the problem or about how to find it ?
Thanks (going mad, yet changed battery, charger and multiple USB flex ports )
You do know that our phone never deep sleeps when it is plugged? There is a specific wakelock for charging, which will keep the freq to 200mhz. As for battery drainage, nothing much can be done because our phone's charging capability is not advanced compared to newer phones and hence it is easy to drain the phone battery even when plugged. Doing simple things like closing all unused apps, keeping the screen off, turning off Bluetooth or WiFi may make the phone charge a little faster.

I did know it, it was stated somewhere in the previous threads. What I forgot to mention is that, actually, I'm talking of an s2 with Greenify activated, no third party background process admitted except Telegram & Whatsapp services but charging in offline mode, screen always off. And still says it will take 2h 45m when charging starting from 65%, math can be done for when starting from 1%.
Time ago it only took about 1h 45m to charge completely, so it seems strange.

Note 3 Pro- can't charge,it shortening the charger/PC USB and charging wire get Hot

Hi all,
My father's Note 3 Pro stopped working yesterday. He left it while charging and in the morning the smartphone was dead.

If I try to charge it the wire gets hot really fast, tried all different chargers/wires(only got high quality chargers/wires).
The charging port is clean.
I have taken off the back cover and all seemed OK- it never got wet!
If I disconnect the battery- still shortening
If i disconnect MB flat wire - not shortening.
SO the MB is fried?
If I can't fix it I will send it back to china to use the warranty.
Thanks in ahead!.
there's a high chance that it fried your motherboard. the cable gets hot because the positive potential of the cable meets the negative one, together they generate heat.
Yes, that what I thought. Now I am waiting to the store in china to reply me How/where to send this device, hope they gonna fix/replace it.
So no I can see how smartphones cause fire and burn damage, it's crazy that all good for almost 6 month and suddenly it can get hot and cause fire.

I have tried with my Samsung's phone charger (it is also 5V 2A), but charge rate remains same. Maybe my phone's battery going weak. But it's not even 2 year. It will in Nov.
And one thing more, actually it get fixed today after updating device. It charged at normal speed (an app showed 45% per hour), I usually don't use that app but I use it now to check charging status.
But now, it became again that slow. (App showing 12% per hour. 7hrs to full charge)

i don't think is a battery issue. also my battery is two years hold. i suggest you the original xiaomi cherger with a new cable. a more power charger is not compatible with mia3 tecnolgy. maybe the result can be a slow charging. are you on stock or custom rom? if you are on a costum rom probably is a software problem.

i'm agree with you
same problem here, but seem resolved with last update. I think it was a loading kernel module problem. the charger is good and the battery too. this is a kernel bug
