[Q] Used wrong charger, battery jumped to 100%

I wanted to quickly transfer something from my laptop to my new Droid Turbo, so I quickly grabbed a USB cable thinking it was my Droid Turbo's cable. I had accidentally grabbed my 2012 Asus Nexus 7 cable instead. I plugged it into a USB 3.0 port on my laptop and after transferring some things for two minutes I noticed my battery was at 100%. I thought this was strange as my battery had only a few minutes ago been 87%. That's when I realized I was using the Asus cable.
Should I be concerned? I usually almost religiously never mix chargers.
Edit: I have just discovered that the cable is damaged and partially pulling out from the USB end.. could this have anything to do with it?

I had the same issue, connected my phone to a USB 3.0 port to backup some date and was shocked at how fast it supposedly charged up to 100%. I used a 3 y/o cable from an old Galaxy S3.

USB 3.0 has nearly double the power output of USB 2.0. So that could have something to do with it. Using a different cable or slightly torn one won't make a difference. The battery percentages also aren't the most accurate all the time. Your battery should be fine.

A USB 3 cable going to a standard USB 2 micro port? No voltage difference.

When using a standard USB cable the port does not matter.

I do think the calibration of the battery is off. I've had it go from 93 percent to fully charged on my qi charger just a minute ago, and yesterday twice, once on the turbo charger and an usb port on my laptop. I fully drained the battery the first day, Friday, and I think either it's still learning or the calibration is off. It seems to show it draining quickly the first sixty percent, then really slow down the last forty. Now I don't like letting the battery drain too low, decreases the battery life and capacity, hopefully it learns or next update clears this up.

This also happened to me on a usb3 port, but with the original cable. I jumped from 88% to 100% in about 5 seconds. This can't be right. Has to be a bug.

I don't think this is related to faulty chargers/cables. I had the same thing happen to me yesterday using my car charger for the first time (that I've used on 10+ other devices without issue) and the phone shot up to 100% in a few minutes. Ever since I used that charger all my other chargers that were previously working fine (turbo, qi, etc.), are charging the phone too quickly as well. I hope someone can figure out a fix for this, or an update comes out soon. I just wiped my device and set it up again, I'll report back if it's fixed.

I had this issue, I killed the battery thinking it would fix the issue when It charged, It did not. I factory reset and that also did not fix the problem. phone would show as 100% charged even when really only 3% charged. I ended up getting a replacement from VZW store.
Update - replacement phone from VZW is doing the same thing, only charger that I have used is a TYLT qi compliant wireless charger. (shows 100% for 6hrs)
Also are you guys on system version 21.21.12 or did you take the update?

Same issue here. Started today. Had since release. Exclusively use Tylt Vu charger. Have latest update. On Dalvik.

Mostly same here. Used the Tylt Vu exclusively, then used the Turbo charger once or twice. Phone was stuck at 100% for twelve hours yesterday, dropped to 93% after reboot. It appears confused as to what it should really be at. Seems that the Tylt Vu is the common thread here.

Fixed mine! after holding the power button for about 20 seconds the phone will shut off, I then charged the phone with the Turbo charger overnight which reclibrated the battery meter. This has not happened again since doing this.
Hope this helps!

This also solved the problem for me, thank you!! (I had also plugged into a usb3.0 port before this issue occured, hope they address this with a patch or some kind of fix).

I'm also having strange battery problems the past few days. The other day, randomly around 4pm I happened to notice my battery said 97%...just not possible since it had been off charger since 6am.. Yesterday, battery showed 35% and then died 2 mins later, powered off. Tried the power button for 20 and charged overnight, but on my qi charger I woke up to it only partially charged and not charging anymore. took off and put back on charging pad and it charged some more until morning. It seems the battery isn't calibrated and not showing the correct readings...anybody else? (oh, and it's a samsung charging pad)

unplug it from everything, hold power button till it shuts off, it will then show an accurate % reading. Plug into the turbo charger that came with it and walk away for an hour. Should re-calibrate and get you back to normal (assuming the issue you're having is the same as ours). this worked for me. good luck!

Sorry, needs to be plugged into turbo charger, I told you out of order, my bad.
plug into turbo charger, hold power till it cycles on it's own (you'll see the real %), leave plugged in and walk away for an hour.
Solved all of my problems, good luck!
(seems like this is caused by plugging into usb3.0 ports, and possibly some qi chargers. I use an lg qi charger overnight and have not had the issue. It happened to me when I plugged it into a usb3.0 port on a laptop).

great! this worked for me! thanks!

Well for me I've had this bug since day 1 and none of the fixes are permanent -- there's a bug in the software on Moto's side that needs to be dealt with. I posted a thread on Moto's support forum in hopes of raising the profile of this issue cause it's a showstopper for people like me who rely 100% on Qi.

Hi all,
I've had this same issue and I'm not sure when this happened, but I certainly noticed it immediately after using Qi charger for the first time.
Can we confirm if anyone on this thread had this issue by using a wired charging device, or whether this issue is synonymous with Qi charging?

Fast charging

Is there a set of rules that it follows before fast charging works? I'm not sure if it's that or my phone or charger is bad..
Seem like I can only get it working 30% of the time. I would have to unplug and plug in multiple times before the notification pops up saying fast charging.
I tried multi USB cables and pushed it all the way in the charger.

I haven't managed to look at kernel source yet (not yet released), but maybe charge type is not only dependant on charging source type, but current battery level. ie top off charging. Just guessing for the moment............

I have the same issue. The quick charging notification never pops up the first time. If I unplug the cable and plug it back in, then it's fine. I'm using the wall plug and cable provided by Samsung.

Don't know. I've only charged my phone 2x, but fast charging popped up both times.

Actually no, I bought the T-Mobile version. I doubt it matters but it's the 64gb model. It sucks that you exchanged yours and have the same issue.

I picked up the AT&T model yesterday. Plugged into my car charger, 2amp, works fine. Got home and plugged in before bed with samsung supplied charger, showed fast charging. Passed out and woke up to 40% battery this morning. Turns out it will connect fast charge (ONLY if i use the supplied brick AND cable), but cuts out after about 5 mins! If i use the 9v brick with a random cable, it will just say cable charging, but seems to be decently speedy and won't stop charging. Seeing how crawldit replaced his and has the same issue leads me to think Samsung really was hoping people would get the wireless pad. Hopefully its a minor software update/patch needed. Phone is a freakin winner on all other aspects. Battery life appears to be better than the note 4 even with a slightly lower mah.

Definitely a software issue IMHO, from the sound of it. Also, on my VZW 32gig I do not have this issue. Every time I plug it in (to the supplied charger) it fast-charged. Cant say if it gives the message every time though, but I know it fast-charges because its never on that charger more than 15-30 minutes and the charge jumps massively. But even on a normal charger it still charges fairly quickly.

Well... turns out my brick was bad, used the one from my Note 4 with the new note 5 cable and it works like a charm. I'd recommend checking out a new brick.

Glad you got it figured out. Mine works fine now as well. I don't know if everything was overly stiff from being brand new, but after a day or two the fast charge pops up the first time every time now.

Wirless charging

Has anyone else had or solved the issue with wireless charging on the Note 5? Mine stops charging after about 10 minutes, other times it will charge to 100%.

i have never had that issue. try your phone at a samsung store with their charger and see if it does it. compare to a demo unit. if it works and yours doesnt on the same charger get a new one..

I bought a choetech charger, charges for 10-15 seconds, then disconnects and reconnects after a few seconds.
Assumed the charger was bad, so I returned it. I like plugging a cable in anyways, charges faster and I can use the phone while it is charging.

I've read of a few people having the issue.

I am not sure what carrier you are on, but I read that Samsung has found a software change that Verizon made on their version and notifications cause the wireless charging to stop working. That post said that they are working on a fix. I cannot say this is 100% true, but after trying multiple chargers on my Verizon Note 5 without it working, I am hoping that is the case and that a software update will fix the issue.

Wireless Charging Stopped Working

Wireless charging on my bundled Wireless Charging Convertible pad stopped working yesterday and I haven't been able to get it to function again. Starting yesterday morning, the charger pad wouldn't recognize the phone at all, case off. After playing around for a while, including clearing the cache from Recovery, I can get the charger to recognize the phone, the phone now says Fast Charging, but the phone continues to drain over time vs charging. Some users in the past have gotten a Charging Paused message, by I don't get that message unless I remove the phone from the charging pad.
I've tried two Samsung Fast Charging AC adapters, the USB cable that came with the charging pad, and an Aukey cable, same results.
Has anybody else experienced any issues like this with their Note 8 or convertible charging pad?
Edit: MST also doesn't work, I'd guess it's related.

Only way to diagnose this would be by trying to charge the phone with another wireless charging pad.
Does your phone charge normally through the provided type-C cable and power adapter?

Found a non-convertible style wireless charger a co-worker had, which charges his S7, but doesn't charge mine Note8. Could it be the phone itself?

I would not rule that out. I would take your charger and phone to a local best buy and test against a display, if your charger charges other phones, then it's your note. Or try your carriers local corporate store, they probably would help as well.

Well I can verify that the phone is the problem. Note 8 won't charge on any wireless charging pad, and Samsung Pay's MST also stopped working at the same time. Going to contact Samsung and see what can be done, hope I don't have to set up a new phone yet again.

This happens to me alot. I have 2 wireless pads, 1 verizon (from my note 7) and the Samsung Fast Charge.. It just stops working randomly.. Reboot the phone, then starts working fine again.

I still use my Nokia wireless pad....I found it charged the time as the Samsung fast wireless charger.

Probably not much help but are you on the latest firmware? When I updated mine it said the new changes were for the camera & wireless charging but of course no other details.
I haven't had a problem with mine though even before the update. I don't have the bundled charging pad though, I'm using the older Samsung fast charge pad.

Good luck. Same problem with my s8+, samsung says its not the phone. But it is. Every problem with a warranty repair is like pulling teeth with samsung. I wish LG would up thier phone game just a little, and I would never buy another samsung again.
Sent from my SM-N950U using Tapatalk

is this after the 9/25 update? Mine stopped charging after that update on both Samsung fast wireless chargers I have.

I have a Note 5 that will not charge on either a normal wireless Samsung charger or a fast charger Samsung pad IF the protective case is on it. This started just this week. I can remove the protective case and then it will charge.

I don't recall getting an update on or after 9/25. N950USQU1AQI5. I did get an update that improved camera performance, but it was a week or two ago. Just performed a factory reset, no luck on a fresh install. I can also confirm MST on Samsung Pay still doesn't work after factory default, they have to be related. Frustrated I'm going to have to deal with warranty. After two Note 7's, going through another Note 8 is beyond frustrating. QA @ Samsung could really use some work.

So Samsung has agreed to repair/replace the phone, but I'll be without the phone for 3 weeks. Since I just switched to Verizon, the only old cell phone I have won't work. Since I bought from Samsung.com directly, Verizon won't help. Samsung.com refuses to provide a loaner/temp phone or to cross-ship a new one. Their manufacturing defect means I have to bear the burden of their problems. I wouldn't care too much about wireless charging, but MST is also affected, and I love MST.
Lesson learned - Never purchase a phone directly from Samsung.com, even if that means getting a discount or promotion.

I just sent my Note 8 in for the Same thing. After 4 weeks of ownership it stopped charging wirelessly.
The Samsung Rep I spoke to seemed to think it was related to the NFC, something about NFC being involved in the wireless charging some how. So MST must be the reason.
I sent my Axon 7 for warranty repair the same day. Luckily I still have my LG V20 and Nexus 6P (with is horridly degraded battery), so I have backup phones.

I'm on firmware AQI5 and wireless charging has stopped working completely. I've tried Samsung and third party chargers, all of which worked last week and still work with other phones. So I'm thinking it's a firmware bug...

Describes my problem almost perfectly. Now on my third VZW note 8. First one charged fast wireless for exactly a month. Second one, worked for eight days. Now the third, 7 days.
All four of my offical Samsung wireless chargers quit recognizing at the same time. FYI; two charge pads and two charge stands all fast wireless and purchased thru out my time with S7 Edge (went thru 2 rounds note 7). To add to that the new promo convertible quit at the same time as well.
Pretty darn sure it's in the phones. The latest phone charged wirelessly to 100%, then nine hours of driving later, no go. Pulled my UAG Monarch off, still nothing. Tried the other wireless chargers, nothing. No new apps or settings changed during my drive. Thoroughly confused.
All three of phones were put thru the ringer with VZW tech support: check this, check that, safe mode and the end all factory data reset, still no go every time. I contacted Samsung directly once, what a waste of time. Their only answer was send it in for evaluation and possible repair or replacement, you should have your phone back in a couple weeks. Second go around with Samsung, I was transferred by VZW. Their answer that time was; send the phone and the charger. Had to reply, which charger, all of them? Samsung, then told me all of my older chargers aren't compatible with the note 8 and must have damaged it. That style of charger is still readily available and advertised as note 8 compatible.
I've never used NFC or MST, so I can't comment on that.
All three phones fast charge on the wire.
Can anyone verify compatibility or lack there of with all these fast wireless chargers I own?
Willing to try anything at this point. I would dump the 8, if I didn't use the pen so much. Been using note phone since the 2.

It's the phone. Contact Samsung for warranty repair.
Just got mine back and its working fine again.

According to the rep I spoke to it was to do with NFC, as it is somehow involved with the wireless charging process.
Sound a bit strange, but others are saying that wireless or MST payments are both affected. So I guess wireless payments and wireless charging are somehow connected.

I don't think it is. I got them to do a warranty replacement, and my new phone worked fine. But, as soon as I wiped my old phone in preparation for returning it, it started working as well. Then, a couple of days later, my new phone stopped wireless charging.
Right now, I am just hoping that the Oreo update fixes it.

Device stops charging when reaching 80% in wireless charging!

Hello People,
I have read lots of posts about wireless charging issues on S10 however I could never find anything about the problem I enncounter.
About 2-3 weeks now I noticed that my device on a ZIZO wireless charger suddenly stops charging over 80%.
I have the device and charger about 3 months and the device was charging to 100% each and every time with no problem.
One day suddenly it appeared the known pause chargng issue several times and after that the device each and every time didnt charge above 80%.
When it reached 80% it stops.
The message saying how much time is needed to full charge doesnt appear or seldom appears.
I tried charging with wire and the device reached 100% with no problem.
Does anyone has a solution or explanation to my problem?
Thanks in advance

My first thought would be to try it with another wireless charger as it could easily be that charger you're using. If you don't know anyone that could loan you one, I guess you could find a seller with a liberal return policy, buy another one and if it does the same, return it. I'd almost bet another one will work.

Thanks for replying.
Miraculously after rebooting one more time the problem didnt exist anymore.
Tried charging 3 times and in all 3 times 100% was reached so probably something was wrong with the device psychology!

Sorry for reviving that old thread but I have a similar problem. Only difference is that my S10+ claims to be completely charged when on the wireless charger.
But as soon as I remove it from there, the charging level immediately drops to about 70 - 80%.
What's the most possible cause?
