i'm having trouble with my s4 i9505. i charge it 100% and when i unplug it and use it, let's say i've played a game for a while and then switch to doing something else like watching a video, it reboot and then it's like it's in a boot loop. but when i plug in my charger it boots up normally. sometimes when this happens it says i got like 70%+ left of the battery but sometimes it says maybe 0-5% left. when it says 0-5% left and i have the charger plugged in it charges up really fast to like 70%% then it charges normal speed after that.
i dont know what the problem is, if it's something with the phone or with my battery. what should i do?
Does anyone know if the zmax can turn on without its internal battery installed? And a plus if it turns on automatically without battery once you plug in the usb charge cable? Thanks! Trying to install this phone as more of stationary tablet. I dont want a battery in it, less hassle to deal with if in case it fails as this phone may be sitting in relatively direct sunlight or general higher than normal heat (but not enough to kill it).
Battery isn't meant to be removed. Not sure anyone's tried running it without it in there.

i tried to today with no such luck. trying to find out how to unbrick it. tried running twrp recovery and reboot into recovery mode and it has not came back on since.
My Redmi 3s can charge only when its in fastboot mode.
I tried charging when it's turned off and on, even in TWRP but without any success.
And even in fastboot the battery gets very hot after 30 minutes of charging.
It started few days after leaving it on the sun and heating it to the point where i could barely touch it so i suspect it might have caused that.
My question is why does it work in fastboot and what could i try to do with it?
I'm planning to flash a new ROM tommorow but without much hope since it doesn't charge in TWRP either.

Mine only charges In switched off mode.:crying:
Hey,
My phon rarely goes into Quick Charge mode, no matter what % of battery it is, 20 or 90. It actually goes QC everytime when it's turned off. It also does not charge from an usb port, nor lets transfer data.
Phone is recognized tho from the bootloader mode so at least I can flash a rom.
I'm getting tired of this.
Anyone?

In oreo it shows as quick charge=turbo power so it will charge as turbo power only,and to transfer data you need to allow it first for data transfer so you can transfer you data.
I can not connect to pc in android, recovery or download mode. Kinda happened out of nowhere, one minute it worked next it doesn't. I've tried all usb settings in developer's options in Linux and Windows and the device does not show as anything. Device manager doesn't refresh on plug/unplug and lsusb and #lshw show nothing at all. The tablet charges fine but not recognized even as something attached while charging. Shouldn't lshw show anything connected while charging? Hardware or software?

Sounds like a bad USB cable.

Nah, disconnected cables(tested 4) from tablet and connected to 6 or 7 more devices and they worked with all of them. Weird thing is lshw doesn't show anything even though it is charging from PC . I thought it should show something if it is draining power. Nothing

If the tablet still runs, I'd try using the Ampere app to see what the charge rate is. If the data lines are bad, the charge rate should remain low because the smart charger won't charge at the high rate if they are bad.

It varies from 1200mA to 1500mA with inline usb ammeter. Down from 1800 that used to display on lock screen but don't know how accurate in-built meter is or which ROM was showing mA. Must have been one of Luis' as LOS 16 shows only percentage and charging rapidly. Slower than normal but not like tab s2 would do, it slowed to a trickle when port was bad with no data. I don't know anymore, turn around for warranty work(if eligible) is 4+ weeks and charg port board to swap out myself is 6 to 8 weeks.

The reason I suggested the Play Store app Ampere for checking the charge rate is that I KNOW how that app rates my charging with a "smart" charger. Close to 2.5 amp. But I have no way of knowing how your measurements compare. The tablet may or may not be charging normally. As for the turn around for Samsung, I don't know where you live but I sent mine in to have the FRP lock removed and had it back in a week.
edit: Just remember to relock the bootloader prior to sending it to Samsung. In fact, that would be my next move. Relocking the bootloader will cause a "factory reset" and just may fix the problem.

Unfortunately I can't relock bootloader . It is stuck on LOS 16 and trying to revert to stock is an Odin only deal from my experience with it. I went back and forth from custom to stock the first few weeks. Restore of backup does not work because of vbmeta, TWRP backup has the modified vbmeta.img from twrp so it won't boot with stock firmware. I have tried restoring stock firmware then flashing stock recovery in twrp followed by dd if=/external_sd/vbmeta.img of=/dev/block/mmcblk0p23 from recovery terminal using .img's from factory firmware. Also tried with .../platform/soc/... and ..../bootdevice/by-name/... all resulting in vbmeta error and booting to download mode. The only way I was able to relock was on stock firmware. To get that I had to flash BL first then flash full firmware. I've done it enough times its easy now, but no data connection no odin. Kinda leery of messing with it too much because if I wind up stuck with vbmeta error there is a good chance of it being one that wont let recovery boot either. Then I will be stuck in download and surely can't send it that way. Options are getting to be fewer and fewer.
