Since 2 months, i am facing this issue where the phone dosent allow the battery to charge, thinking that the phone's battery is dead - i replaced it with a new one, but the phone still dosent boot, what happens is that when i press the PWR button on the phone i see the first screen with the red light blinking, and then turns off, but when i try to pwr on the phone with the PWR cable plugged in it works fine,
can any help me on the possible issue on the phone,
Looks much like an internal failure but check for any charging voltage at the battery spring contacts - also make sure they're physically ok.
I'd think that if the charging light only comes on when the battery is inserted its a sign the phone recognises but cannot charge the battery.
It's not unknown for a brand new battery to be faulty.
Last night i was using my phone right before going to bed. The battery was at about 18% or so left. I got up to get a glass of water then came back to plug the phone in to the outlet only to notice that the red led was not on. I pressed the power button and nothing would happen. The phone completely shut off without interaction. So I panicked a little and plugged to PC USB cable that was attached to my PC and nothing. wasn't detecting or anything. so I press and held the power button and plugged it in at the same time and it powered on again. Anyone know what could have happen?
Only time i faced this problem was when i tried to drain my battery completely. it wouldn't shut down on its own when it reached 0%, so i turned it off myself.. The next moment is wouldn't boot or charge also. Then i held the power button and it came back to life.. Don't know what the exact cause is though

Yea it kind of turned me off on the phone. But I still love it. anyone else have a similar issue like this? I'm hoping that it is the power management issue that some people are having as there is a quick fix with that. I was avoiding rooting or modding my phone, but I might just have to now.
i'm a noob so i don't know much about most of this, but this really sounds like the way my ipod functions if i let the battery "die." i can't imagine that any manufacturer making a phone with a non-removable battery doesn't have it set up to be rechargeable upon plug in.

Ye, furthermore i've read that this is cause but letting the battery ''die'' indeed, it takes time to charge it back up because when you let it die some kind of undervolting protecting is kicking in i guess and soon after it will start to charge
Hello XDA members. I have a very troublesome issue with my galaxy tab 3 7.0 inch tablet. It will NOT turn on at all, no battery charging, no device power on, no comp recognition, nothing. I have already tried:
Letting it charge overnight (factory charger along with others) with several known working cables
Unplug battery for 5 minutes
Press and hold power, Vol Down, and home for 10 sec, 30 sec, and 1 minute
Press and hold power and vol down for 10,30,60 seconds.
I sent it in for repair and they wouldnt fix it because it's rooted. When I got it back it briefly turned on to the battery charging, but nothing since. I'm thinking there must have been some way they got it on.... All proper drivers are installed on PC and it's never been dropped, water damaged, etc.
Would anyone be able to provide insight as to why and provide a fix?
My 8 inch tab 3 wasn't coming on either a few days back, I got it back on by holding home and the power button for a while. I was about to give upwhen the battery charging image came on. I think I did the same again and it came on normally.

Was that from computer or wall?
From wall, it was about 3/4 charged by then

Still no luck... I can feel the tablet getting hot down at the charge port so I know it's charging, and i know the lcd isn't damaged.
Mine is in the same condition. Anyone know how or why this happens and how to fix it?

Not sure if this will help, but just like with phones, sometimes android tablets just need a battery pull. My kids xo tablet went dead and before I tossed it in the trash I took the housing off and had to clip the + wire since it was soldered to the board. Twisted it back together to check and sure enough the tablet powered on like normal. Ive had to pull the battery on an Sm-t217a and it was a lot easier. They have a removable clip that attaches to the board.

I think it might be the battery itself. Just for giggles I left it plugged in for days and i just checked back on it and the Battery charging screen kept flashing on and off. Won't hold any charge. Probably will just order a new battery and see what happens. I pulled the battery a couple times and nothing happened. Closer inspection found that the tech that looked at it damaged the battery cord (unless it came with the copper on the wiring already exposed...)

You might be right about the battery being dead, although they usually don't just go all at once like that. The charge indicator flashing is odd. The only thing close I've seen is an "x" over the icon when there aren't enough amps (my tab needs 2 amps. 1 amp chargers and some pc usb ports give me the x.
If you have an old cable you can cut, you could try to charge the battery itself to see if it takes a charge (or at least use a multimeter on it to check for voltage). Then you could narrow it down a bit to whether it is the battery or possibly the charge port/hardware..... I saw a bit of exposed wire just before the clip of mine too, made me extra careful pulling the clip up.

I wouldn't even know where to start with the wiring. Multimeter isn't something I have access to, and it seems a little complicated for me to spend time on.
When I say it's flashing, I mean the device powers on to the battery charging screen, then dies, wash rinse repeat. If I go into recovery, same thing. It all happens within a couple seconds, so it's hard to describe.
My dad has one that I can pull the battery from, I might do that. Batteries are like 20 bucks on amazon, so I think I'll test with my Dads and if it works just order a battery and report back here.
similar problem here

My daughters tab 3 7 inch T210 also refuses to start. First time it was fixed by opening the device and disconnecting the battery. Now that doesn't help anymore. If I attach the original charger and measure the voltage when the device has rested for some months I can see that the voltage slowly rises so it seems to do the charging even if there is no sign of charging on the screen. After some hours of charging I measure 3,78V on the battery, after disconnecting the battery.
If I attach the battery and turn on the device I measure 3,76V before I push the start button and 3,74V directly after pushing the button. After about 15s the voltage goes back to 3,76V. Nothing happens on the screen... Tried with different combinations of pushing on-button and volume up, volume down, menu....
So -the best thing would of course be a quick visit to local shop to buy a new device of another brand but for some reason I refuse to give up.
Any advice would be appreciated.
(I Have made no significant modifications but the 4-year old daughter may have contributed in an unknown way )

The better way to test if your tablet can turn on: buy a new battery, under $15 on Ebay since your old battery is dead or completely drained.
Use the new battery to turn on your tablet. If it's on, check the build number of your device after go to About My Device: if it's not end with OB1, the latest firmware which fix charging issue.
It's more likely your build number is MK1 to NI1, the build numbers count by alphabet order. Upgrade the software via Wifi, battery must be at least 25%, otherwise your tablet won't allow you to upgrade. Bring the firmware to the current OB1, your tablet should take charge normally, otherwise the USB charging port is defective or damaged. This micro USB is cheap, around $2, but it need to solder to motherboard to replace the defective one.
Hi all, my Nexus 5x wont charge but Red led is blinking and then nothing happens, I broke the originale LG type c cable and I left the phone discharged for 5-6 days until the new cable come, and now It wont boot nor charge with no cable or Wall charger combination, searched on web and found people saying to let It in charger overnight then try booting and similar things but nothing is working.
anyone here got this problem?:crying:
Hi, I had the same issue... and charging overnight will not fix your problem....
it happened 5/6 times to my phone, the only way to make it works, was to pull out- pull in the original charger, and after 10/20 times you do this, it will work again.
I bring it to LG assistance and they told me that sometimes, all the updates and the full memory (mine was not full, but 17gb over 32) made this. I didn't believe that, BUT an hard reset of the phone and it never happened again in 3 months
Hope it will work for you too

Thanks, I will try, but how much time do I have to wait before pulling out and pull in again the charger?
Can anyone help me please?
I had the same. I forget about phone and left it with TWRP running. It drained all my battery and phone wont turn at all. I had this same red LED, so i plugged phone to charger and after maybe 2 hours it turned back on (charging screen), wnother hour and my nexus was fully restored with full charge.
Also i recommend you to get original charger and original usbc cable. Also before it you can hold power button for 30 sec. In some Xperia phones even a few days can do a trick.
Finally understanded the problem Thanks to "Dusan Milanovic"
In my case it was:
- 50% Battery problem
- 50% Qualcomm Power IC Chip
How I solved it:
I AM NOT RESPONSIBLE FOR EVERY DAMAGE YOU MAKE TO YOUR PHONE, HOUSE, GRANDMA.
REQUIREMENTS:
- Alluminium foil (biscuit metallic paper) not plastic
- Hairdryer (It seems stupid ahah)
- Chronometer
- Attention!
- A bit of patience
BATTERY PHASE
- Open the Phone and remove Fingerprint board.
- Remove the Battery.
- Put the battery on an universal charger.
(do this only if you are sure that the battery is discharged and don't want to charge)
Let it charge for an hour more and less.
POWER IC CHIP. PHASE
- Remove the metallic protection between the camera and the battery slot.
- Look for a black chip surrounded by little grey chips. (POWER IC)
- Protect everything in the motherboard with the Alluminium foil except for the black chip.
BE VERY CAREFUL, PROTECT EVERY SINGLE GREY CHIP NEAR THE POWER IC CHIP.
-Prepare the Chronometer 1 minute.
(NOT MORE THAN 2 MINUTES OR YOU MAY SERIOUSLY DAMAGE THE MOTHERBOARD)
-Use the Hairdryer to heat the POWER IC CHIP
(DO NOT USE HEATGUN). The chip needs to reach around 100°C
-After you heated the chip let it cool down for a minute or two
-Remount the metallic protection.
LAST PHASE
- Put the battery on the phone
- close everything
- Try to boot it
ALL DONE?:highfive:
POSSIBLE PROBLEMS
- always shows 100% battery. → buy a new battery( this one is Dead)
-Doesn't boot.↓
→Are you sure your battery is charged?
No: charge it externally (BE VERY CAREFUL THIS COULD BE VERY DANGEROUS)
Yes: then try to heat again the POWER IC CHIP (2 MINUTES MAX)
→Still nothing?
- Buy a new Battery, this is the best choice.
- If even after you use the new Battery the Phone doesn't boot , just heat again that pain in the ass of a ic CHIP.

HARD RESET instructions or link you followd that worked drop below
I just had the same thing happen. Using the original charger I kept on charging then trying again and again. I would leave it overnight unplugged from the charger. I think the battery was draining due to screen not coming on but phone booting over and over. Finally after about 6 times, I saw a battery symbol, then pressing power it came on as if everything was just fine.
I found another way, though be careful. Repeatedly unplugging/replugging did not help. Disassembled phone (lots of guides), unplugged battery. Measured 2.96v - too low for lipo. Used lipo charger (100mah) to boost charge to 3.2v. Reassembled, and it charged OK.
Cause is probably voltage dropped below the low charge threshold for lipo charging cct onboard. Lipos are very tricky to charge - lots of papers on this. In theory Nexus should have shut itself down before voltage dropped that low - but it didn't. Design flaw.
i had red blinking but battery was empty.
since in bootloop it will not charge, after i repaired reflow and patched the boot
to 4 core it worked perfect.
so if someone comes here and wonders, it might not be the charging chip
just the battery empty
So I have got this Nexus 5x, I was able to purchase it cheap because it was a return.
When I received it, it wouldn't boot up. So I stripped it down to look for the obvious signs. Battery problems, water damage etc. Nothing like this was present so I thought id disconnect the battery for a few seconds and plug it back in. It still wouldn't turn on.
I didn't realise, but I still had it plugged into a power source when I disconnected the battery. Please keep in mind that there was no skin to board contact, all tools were plastic so there was no problem there. When I disconnected the battery the phone vibrated and presented me with the 'Google' screen.
I thought this was strange, and every time I would connect the battery it would shut off, weird huh?. I thought it would just be a dodgy battery, so I ordered an official replacement battery which arrived yesterday. It's still doing the same thing.
I would like to think that it's a system issue, so I was going to flash official/custom rom to see if it fixes the battery connection problem but the power coming through the USB isn't enough to keep the phone alive whilst going through the flashing process.
Does anyone else have any thoughts on what could be going on?
