[Q] Zenfone 2 not charging AT ALL. Now it's dead.

Hi. I got the Zenfone 2 about a month ago and hadn't had any problems with the battery until today.
I had to transfer files from the phone to the office's PC (at home I use bluetooth to transfer files so I never needed to connect it before).
This PC didn't have bluetooth, so I plugged in the phone through my USB cable to use Asus PC Link.
When the 'turn USB Debugging Mode ON' message appeared, I pressed 'Yes'.
The PC didn't recognize the phone, so eventually I disconnected it again and sent the files using WeTransfer (app which I then deleted).
After an hour or so I connected my phone to a portable charger, and the charging icon and light lit up. I realized after a while that it wasn't actually charging, cause the battery percentage had in fact gone down instead of up.
I didn't worry at the time, but as the day went on I tried different ways of charging it (another person's cable, connecting it to the PC, etc) and the battery kept draining.
When I got home it was at about 10% and I was hysterical, so I connected it with the standard charger that came with the phone, but it didn't charge either. (Though, at ALL times now, it kept showing the 'charging' icon, even when not plugged in).
Then, at about 4% it turned off, I think to avoid running out of battery completely.
I couldn't figure out what the hell happened, but then I thought: COULD IT BE that turning on the USB Debugging Mode made the USB stop working for charging the phone?
So I decided to turn the phone on and turn USB Debugging Mode off ASAP, but now it wouldn't turn on anymore and the 'empty battery' icon appeared.
Soooo, I have a phone with an empty, non-removable battery and I can't even turn it on to fix (what I THINK is, and I could be wrong) the problem. At times, when I plug it in, it has a little plus + sign beside the battery, but it still doesn't charge.
Does anyone know what the problem might be and how I could solve it?
What can I do? Besides CRYING A LOT.

Have you tried another cable (perhaps a friend's that you can verify works) and checked the phone USB port for debris?

I tried two other cables and it didn't work, but I'll keep trying. The USB port seems to be clean. I'll look at it some more, though, with a strong flashlight, see what I can find. Thanks.

Are you using the 18w Boostmaster adapter? Please note only 2.3GHz plus 4G ram (ZE551ML)" is bundled with 18W adapter, while other spec bundled with 7W adapter. Please see http://www.asus.com/us/support/Sear...5-480F-AADA-FE49EDD81C01/?keyword=boostmaster.

I bought the 2gb RAM version, which doesn't come with the quick charger, but I just charged it with the normal charger that came with the phone. I didn't need fast charging. It still isn't working, so I'm gonna send it for RMA service this week. I have a question about that: do I need to send the original box with all its contents or just the phone, usb cable and charger? Thanks.

Connect it to a computer with an USB cable while the phone is off. See if it charges that way. If it does, don't turn it on while the charge % is low.

Just so you know, activating the USB debugging mode cannot cause your battery issue.
You mentioned that you saw the charging icon being displayed while the cable was unplugged. This makes me think you may have bent/damaged the usb charging socket and some pins inside are doing contact when they aren't supposed to, but I'm not sure since I cannot see your phone.
If the charging port is not damaged, then it's a battery problem. In some cases it can be fixed by physically disconnecting and reconnecting the battery from the motherboard. Beware, this is not easy and if you are not careful you can damage your phone. Also I don't know if this will void your warranty. What you have to do, is disassemble your phone until you have access to the battery, then unplug the battery, wait 1 minute, connect it again and put all pieces back where they belong. This might have a 50% chance of solving your issue.
Disassembly guide: http://www.myfixguide.com/manual/asus-zenfone-2-teardown/ (Do all steps until they remove the battery).
If the usb/charging port isn't damaged, and reconnecting the battery doesn't solve the issue, then your battery is dead, and you have to contact ASUS to get your phone replaced.

Dear Blasterkat101,
Please do not send in original packaging as it may not be returned. For power related issues we recommend sending in power adapter and USB cable with unit. If this is a USA/Canada model Zenfone 2 and you would like me to assist with an RMA, please send a private message to [email protected] with case # N150721539 in the subject line.

Thank you so much for answering! It made everything clearer. I was about to dissasemble the phone, but I was afraid I'd void my warranty or leave it in an even worse state than before, so yesterday I sent it for RMA and I'll see if they can fix it. If they can't find problems with it or tell me they can't fix it, I'll have to choose between returning it or keeping it and trying to fix it by myself (but at this time getting my money back would be pretty useful, so..).
Nevertheless, your answer was very useful and so I thank you! If at any time I have the need to dissasemble my Zenfone again I will be able to do it

Thanks, I sent only the phone, cable and adapter yesterday. I'll wait now

I've got an RMA question if you can help. Is there any way to not have to pay the $25 for the RMA? I've got a 3 week old phone and tech support wants me to pay $25 for the process. That seems like a steep price to address a problem with the phone that isn't my fault.
Dan

On a sidenote, never use a cheap powerbank as I had charging issues with another brand phone and it eventually died. Battery charge would jump from 40 to 100. I learned my lesson to only use same brand powerbank/chargers or any quality QuickCharge certified accessories from other brands like LG, Samsung etc

I have the exact same problem. Has anyone been able to fix this or the only solution is to send it to ASUS? My phone is only 45 days old!!!!!

Apologize for the delayed response. Unfortunately the $25 is the processing fee for an advance replacement. If you would like to send in for warranty service there is no charge to you. For more details with advance replacement please see http://www.asus.com/us/support/Article/744

The phone still charges but I have to move the usb cable around a bit to get it right then set it down and not touch it. It won't charge it otherwise.

Have you tried with a different USB cable? If you decide to send in for service it should be covered under warranty but cannot guarantee it. The repair center will determine that once its inspected.

charging
Hi I'm in Mexico and bought an ASUS_Z00AD in Hong Kong, I think is the WW version, I have problems trying to charge the phone, it only charges with the charger that came with the phone (is not the one with 2 A is the 1.35A) , I have tried to charge with two different power banks and even when the light turns to orange and shows the battery icon charging it doesn't charge, the same happened if I try to charge with my computer.
The other day i let the phone completely discharge and took me very long time to power on again.
What can I do
regards

Try cleaning the charging port on the phone and see if it helps any.
With the stock charger, I have found that sometimes it doesn't want to quick charge so I have removed the cable, flipped it over and it works fine. Not sure why, but it works.
Outside of what I've mentioned, a new cable and/or charger may be in order.

S9 Moisture Detected in Charger Port message, port is dry and clean, never been wet.

SO yeah, I've seen where people have had software issues causing this on the Note 8, and S8 models, is it a bug that crept into the S9 as well? The tech at the Sprint store verified the cleanliness and dryness of the port, thinks it's the port, and they won't have parts to fix it for probably a month or so. I REALLY don't want to send it in to be fixed, so I bought a couple wireless chargers.

It it showing constantly or only when a cable is plugged in? If it's with a cable, have you tried other cables? I had my phone give me that message earlier today when plugging in an incompatible hub. The hub wasn't even connected to anything.

Have you checked with your wife?

All the time. It has a popup with sound when you plug it in. The rest of the time, it's just a notification in the tray.

Yeah, tried rebooting, wiped cache, power down all the way, multiple times. Tried plugging the cable in while booting. It looks to be charging while plugged in and powered down.
So, the message went away, and it would charge with 2 different chargers, normal speed, not fast charge. Would not work with a charger I have here at home. None are Samsung chargers, but all are QC 3.0, which will report as fast charging on the phone. Then today it charged fast in the truck, and the one at home works, but only slow speed.
I'm not going to stress over it as long as the fast wireless charging keeps working. The battery life is more than enough to get me through a day, and I'm ordering stuff to integrate wireless chargers into the vehicles.
Thanks for reading and trying to help!

I probably missed to ask before, but are you sure you are using the original cable, together with the original power charger?
As stressed by @DeadlySin9 the problem may be the cable. Try other cables.

Yeah, I had tried the original cord and charger. whatever it was effected the phone before even plugging it in. The message would be there in the notifications, then plugging the cable in would set off an "alarm" telling me to unplug it and let it dry.
A couple weeks later and it is working just fine, charging with pretty much any cord, and charger. Ugh. I hope it stays that way! LOL At least Sprint DID give me a pretty good discount on a 2 pack of wireless chargers, which is what I use most of the time, now.

Thumbs up!

So, I've had this problem with my new Galaxy s9 as well. Here's the specifics - this only happens IF the phone dies from running out of power. If I let the battery drain on accident, I plug in the device...new cord/charger, original cord/charger, doesn't matter...and it shows the charging symbol for just a second, and then warning there's moisture in the charging port. There's not... If I set the phone on top of a wireless charging pad for a few mins, it charges just fine.
All I have to do is get 3 - 4 % so I can power on the device and get to the home screen. If I can get to the home screen, I can plug the phone in with the cord/charger and no problems.
I just did a warranty replacement because this problem is real annoying. I don't let the phone run out of power often, but sometimes when I'm traveling for work or camping with scouts, it happens. So, before I sent my old phone back for the warranty swap, I let the new phone run out of power and then tried to plug it in. Same error!!

If anyone has this problem follow this trick. "connect the charger half to the charging port." that is it. works fine to me..

Quick Charge 3.0 and USB C not working

So charging is extremely slow now: max 280mA showing in Ampere app. Tried different cables and chargers(QC3.0 certified), charging speed remains the same.
I can't connect to PC anymore. Windows doesn't even make a sound when I connect the phone to PC. Showing no device.
Headphones connected to USB port are playing only one audio channel.
I've been using LOS 15.1 since last summer without problems, haven't done any updates since. The problem with USB port emerged a month ago and I am almost convinced it's a HW issue. AIDA64 indicates no temperatures over 36°C in thermal section so sensors are working fine I guess.
Anyone tried these charging ports from Aliexpress? Comments indicate that they are not the same as the original.

It really sounds as hardware problem. I asume you already tried with the phone off, and after factory reset and the problem persists.
In my experience, the original lower board have fuses which are expensive and are replaced by resistors on chinese replacements. If you dont want to lose this, try going into a repair shop and have the USB-C port replaced or desoldered/resoldered from the board. Must be done by experienced guy or it will be melted.
I'd buy the replacement board anyway. As long as you don't use crappy chargers, you shouldnt need the fuse too much, and also, the phone have another fuse in the motherboard.
If you have not tried with the phone off, try it. I got the xiaomi wireless charger and it works like crap with the phone on. it disconnects/maintains chage/stops charging A LOT, but if I charge the phone turned off it charges without issues at full power (8-10W according to my USB meter). Maybe is just the firmware being an ass

Thank you for insights. I confirm that hard reset nor charging solved the missing QC3.0 functionality. It's clearly a HW issue.
The whole situation was caused by losing my original charger on a trip and then using certified QC3.0 charger (not from Xiaomi) and unfortunately - cheap Chinese micro USB C cable. I can't stress this more... Never use cheap cables (or chargers) they can literally fry up your port. In this case it was definitely the cable eventhough it worked fine for 5 months.
It seems (from comments) that beside fuses the charging ports from Aliexpress are missing the possibility to transfer data over USB as well. Which is not that crucial because FTP over WiFi is bearable. The real problem that I need to fix is quick charging because with 280mA on Ampere app it takes 5 hours to charge this phone.
The charging port I've bought on Ali is on its way so I will update this thread in a few weeks after inserting it into the phone.

Losing data over usb is quite a problem if you are into custom roms/mods on native miui (which resets the recovery on each update).
Hope that ali's board does have this funcionality. About charging, you can get locally a wireless charger for now, though for me it only charges fast when the phone is idle, using it always just keeps the charge (probably to avoid overheating).

So how the story ends? We're you able to solve the problem?

I had the same issue with my Mix 2. bought a replacement port from Aliexpress and Witrigs.com. As posted on most forums these replacement ports don't support fast charging (in most cases) and no USB data transfer (this is the case with mine).
I had dropped a message on the witrigs.com website to confirm if their supposedly 'OEM' replacement supports data over USB (it looks much more like the original board in the phone that the 'custom' replica one that is half the price).
but I'm not very hopeful of that being the case, given someone has already left a comment on the product page indicating they bought the OEM version and faced the same issue with no quick charging or USB data transfer

Got some problem when i lost my usb travel charger on a trip.
and now my phone was too slow and cant transfer data even if i buy the new authentic from xiaomi store.
i hard reset for 3 times and but no luck.
omg -___-

I know it's old, but I'll let you in on my problem.
I have the Mi Mix 2 and it was happily fast charging until recently. Still the original plug and cable
I have tried all sorts of theories to get it fixed and one person said to charge it while turned off
So I plugged in my usb cable and turned off my phone. Only for it to automatically fire up and go into fastboot. No charging. Just fastboot on the screen
Obviously I can get out of fastboot mode again, but is mine an option change in the settings that needs addressing?
Thanks

RN5 Global won't charge

Hi all,
I have a ~2 year old RN5 Global. About 1 week ago, I noticed that it won't charge anymore. When I plug in the charger, the charging icon switches between on and off every second.
After the battery died, I was able to charge it to 68%.
I already tried different chargers and USB cables. I also changed the USB charging port.It doesn't look like the original, however, the problem remains.
Does anyone have an idea what I can try?

Update: I just replaced the battery. Still same behavior as before.
Does that also mean at the same time, that is it not a software issue?

Hi, I already replaced the whole USB charger port/board which incl.the USB socket. No luck I also tried different cables and chargers. Symptoms remain.
Any other ideas?

Hello, got any news on this? I have the same problem; replaced the USB-Port and the Battery. Still it does start- stop - start etc.
