Battery over heating

Battery heats up when charging. Very hot
Sent from my Nexus S using XDA App

What charger are you using?
Go to your dialer and dial *#*#INFO#*#* then select Battery Information.
What temperature is it showing when it's charging?

Its normal for the batt to heat up when its charging..but to an extent

I got the rockfish from best buy. It only heats up some times

Yes that's normal, but you said it gets very hot, and again, read my first reply to your post and tell me what you see, then we can tell you if your heating is normal or not.

make sure you turn off WiFi when you are charging the battery on your SNS
else it heats up really really fast and hot
that was the same on the SGS

Dude at bestbuy told me that chargers other than stock were frying the batteries

i wouldnt even listen to someone at best buy even if it what he told you seemed favorable

It seems common behavior on the Nexus. My NS got up to 105° F last night (to be fair, it was under my pillow). I've simply taken to turning it off when I charge at night, but seeing as my NS is a glorified PMP (and therefore I don't have to worry about texts or other notifications on it), you might feel differently about simply turning it off.

It's interesting to note that the adapter for the Nexus S actually charges at(and I'm sure I'm getting my terminology wrong, sorry electricity guys!) .7AMP vs the 1AMP that other smart phones charges at such as the Nexus One.
This might account for the seemingly longer charge times we've had reported, and why you might be seeing increased heating from using a third-party more generalized charger. Whether or not there's any truth to the idea that it may cause permanent damage to your device, I don't know. I would greatly appreciate it if someone more knowledgable about this kind of thing would post, as I'm considering buying a second charger/car charger. In any which case, I personally take what Best Buy/T-Mobile/anyone's first level support tell me with a great big grain of salt.

google maps heating phone up
I just had a similar experience with my Nexus S getting really warm while using Google Maps this morning. I usually use Google Maps in Car Mode with traffic overlayed as I drive to and from work (~30-40 min. drive). This morning I noticed the phone got really warm by the end of my commute, which did not happen the previous 3 or 4 times I have used Maps in this same fashion. I will take nxt's advice and check the temperature on the phone next time it heats up again. Does anyone know what is a "safe" upper temperature limit for the phone or battery? I've read that higher temperatures are detrimental to the life of a lithium battery.
Other than this one time, I have not experienced any other high temperature issues with my Nexus S in the ~1 week that I've had it.
Thanks ahead of time for any help/advice. This is my very first smartphone and I am eagerly trying to absorb as much information as I can about it so I can determine what is normal/abnormal behavior. I am loving my Nexus S so far!

I don't think third party chargers are to blame. In fact, I'd go as far as to say the opposite is true. I read that the shorter data pins on the official charger cause the device to enter a faster charging state, as compared to the usb cable or third party chargers.

I've yet to feel my nexus s get warm at all... during charging w/ wifi on. Using samsung wall charger, using LG wall charger, using computers w/usb cable.

My NS gets hotter to the touch than my Vibrant ever did, but when I check the battery temperature it is never as high as my Vibrant used to get.
When charging in the car and running Navigation + streaming music the Vibrant would hit almost 125F whereas my NS tops out at 110F.

Well that kind of sucks if you're using it to Wifi tether and want to charge you SNS while you're doing it.

Bump.
Today was the first time I've felt my Nexus S get super heated when charging. Never happened before. I've been charging the same exact way since owning the phone back in December.
Odd.

it depends on the usage
when i download TONS of stuff via 3G or WiFi it heats up a lot, only if i have it plugged in to the charger, else it does not heat up
However! if you check carefully, or better yet, if you take out the back cover
you will notice it is not the battery that is hot, but the area beneath the SIM card that is hot, which points to be the CPU

I see, thanks. Will keep in mind.

FWIW, I have been charging my Nexus S with the Nexus One charger (1 amp) since day 1 - I can't stand how short the stock charging cable and wall adapter were. I haven't had any unusual temperature spikes when charging at all. I don't even really notice it getting warm under heavy load - unlike the Nexus One with the aluminum casing that conducted heat very well. Edit: I also leave WiFi on with a No Sleep policy when I am at home and I've not encountered any warming issues either.

I would be careful if I ware you.. high heat is dangerous for the battery, it might swallow and even a leak if you will keep using your device constantly at high temperatures.
I Have never had any problems with heat and I have been using it a lot.
btw, I use stock rom..

[Q] Help, Please! Changing is soooooo long.

To full chagne the battery, need more than 10 hours. Tried different ROMs, Batteries, changers, cables. the same result.
It looks like a hardware issue...... but....
when I used a DC power supplier(5.2V, limit to 1A) and plug in the cable, it appears the DC current is 0.5A, and after 10 second, fall down to 0.1A. at least, in the first 10secend the hardware worked all right...

Do you use the original OEM charger ?
Have you tried a different charger ?
How old is your Note ? Have you tested a different battery too ?

I was quite surprised when I switched to the Note from the Dell Steak. My old phone would charge much quicker. The Note takes about six hours to fully charge I'd say. As a result I plug it in pretty much whenever I can.

Yeah, Mine can take around 5+ hours too if im charging it from <5%
Bear in mind that it is a bigger than normal battery, 2500mah.
But if it is like you say, Taking 10+hours to charge, Id get it looked at, Maybe send it off for repair or something.

Isn't it bad to constantly charge your phone even when it still has battery?
I heard it reduces the battery's life span.

I dont believe it is, I often charge mine even when its got plenty of juice left.
It may reduce life span, But the battery will live longer than the time you will own the phone so i guess it dont matter

No one can help. feel bad.
I saw sevral links saying same problem, but no solutions... poor us...

From what I've read, it's what you're supposed to do with the current generation of batteries. But then there's so much crap floating about about batteries it gets hard to figure out what is reliable info.

And this is with the original charger? If it's not an official charger, there's a big chance the phone will draw only what's usually allowed across USB. Which isn't much... In fact, with USB, the power draw of GPS/screen on/games can make your phone discharge even with the charger on. So try the official charger, on AC power.

Same problem...
I have the same problem.
At the beginning, about 3 months ago, my SGN works fine, battery are charged to 100% in 2 hours maximum.
I'm buy the phone from a Samsung Store, all accessories are originals. Today I send my phone to the technical assistance and there's no problem with battery or the charger.
My problem stars about 3 weeks, with an alert about different voltages after a full charge, the problem was solved only removing the battery and waiting an hour. At the technical assistance, the answer was to charge the phone when it's shutdown.
I already try that, format the cache, rebuild the system, everything using the ICS LQ3 from Baltic.

Is the problme solved after remove the battery for 1 hour?

paddyzou, the problem with the wrongs voltages, yes, my steps to solve this:
- Full discharge
- Shutdown of the phone
- Remove the battery for 1 hour
- Full charge with the phone hang out
The problem with the low charge I think that was okay, it's seen to be happen in random times, I just flash another LQ3(France) version of ICS yesterday and seems to be working fine.

appreciate you so much. Hope it works.

Mine takes around 2 hrs to fully charge the battery. I use supplied samsung charger.

This is correct, a chemical reaction takes place while the battery is discharging and is reversed when charging(changing). The chemistry of the battery changes how they hold energy. The Lithium ion batteries in our phones can be charged any time, they have no "memory" characteristics like previous rechargeable batteries (NiCd).
OP, it sounds like your charger is going. My stock HTC charger (2-3 years old) now only charges at about 40% the speed, which means the phone will discharge while its plugged in. I recommend grabbing one of those tiny square usb chargers (1A 5v, not 0.5A). I got one for like $6, as long as its 1A it will be quick.

What a cluster this thing is to charge...

The note is a disaster for me when it comes to charging.
If your battery is low and you start charging it but using it at the same time, it doesn't get worse, but it doesn't get better either i.e. actually charge the thing, it just holds its own.
I have got to say I am not impressed with this!

I am not facing such problems. Charging takes pretty long yes but not as bad as you said. A larger battery will of course need a longer time to charge. But I wonder sometimes too if it's the battery problem or the charger output problem and if there's a way to speed up the process.

I think it is more to do with the actual charger, seems like a trickle charge or something.
Yes if charging and using at the same time you would not expect it to charge as quick, but mine doesnt really charge at all, just stays the same.
My acer iconia will charge like lightning even when i am using it, smaller battery or not it still charges!
This was one of the things i was looking forward to with the note, but this slow charge seems to make it more or less the same as what I am used to.
I have the usb plug which comes with the kindle, might it do a better job?

If anyone manages to find a proprietary charger which can produce better charging I will like to know too

That is common the charging is very slow and if you are playing HD games then the charging is almost in negative. May be its because of the voltage of the charger inputs and it is to low. Samsung must have done it for a reason may be its because of the proprietry port or the battery itself we do not know but we need to live it

Agreed, charging this thing takes a long time. Keep in mind that the battery is 7000 mAh and the charger is most likely a 2 amp charger, pegging the charge time at around 4 hours with no other losses. So if you're using it, it should take even longer.

No such issue here. I charge to full capacity while using all the time.

I get what he's saying. Because it draws so much power when you're using it; having it charging at the same time doesn't move the needle much. For example, if you're watching a movie while it's charging you'll probably be at the same point battery wise when the movies over. People complain about this all the time when their using their devices as a GPS. In some cases not only doesn't it charge but it actually continues to drain so you're worse off from where you started. We're using 21st century toys powered by 20th century battery technology.

This is a better way of saying what I mean, thank you.
I also have to say one thing I do not like doing is turning the screen brightness down. After all we all get these things as they look so good, so I am not going to make it look worse when I am using it, what would be the point in that? Its a bit like saying yeah my battery life is 14 days but actually it is on standby for that time lol...
Anyway, I still believe it should be better and the primary cause is the weak charger for what ever reason sammy decided to make it that way, but its not a good thing.

It seems like I remember someone recommending a charger that was more powerful so the note would charge faster. Can anyone confirm this?

What a fail thread. If you know ANYTHING about charging, you would know why this happens and why this is NORMAL.
But why even search or educate oneself, let's post a thread on XDA and whine a bit.

It could be worse. It takes six hours to charge a N10.

I dont face this problem i charge mine when surfing the wep

On a slightly related side note, doesn't it suck that the brightness just turns down completely when the battery is low?

The zslower charge rate protects the batteries life ,reduces the possibilty of heat and battery damage trickling insures a full charge

if you don't want your screen to dim don't use the power saving setting.

For all those facing the slight unresponsive screen please change the source of power, I had mine connected to UPS power supply as soon as I changed and connected it direclty the problem was gone.
Even if you read the user manual of Samsung Note its says thats one of the reasons

How Manhattan hours per day do you use the note? With a 10hrs battery life I find an overnight charge is sufficient

Wow! many friends?
Anyway moving on.. so i just got my note 10.1 about a week ago, loving it but saw that while plugged in it was not charging at all while i was using the tablet and never quite getting to 100% overnight. By not charging while using, i mean to say that it was actually discharging. Yes of course i am using the stock charger and cable.. and even stock note.
so just tried something silly. Unplugged and plugged the usb from the block repeatedly about 5 times. Now its not only recognizing and charging, but charging relatively quickly even while using. To test, i unplugged for about 20 min and plugged back in. Same great results.
Just thought i would share instead of hoarding my new found knowledge like others..
Quick update: it charged about 10% in 20 min.. Nice

I don't charge mine - I paid cash for it

Faulty battery?

I've had my axon 7 for 4 days. Good phone BTW. But this morning I woke up to charge my phone only to be woken up by the disconnecting sound. Battery at 30 and it refuses to go any more. Defect? I think so! Damn! Right when I thought this phone will be puuurfect. This happens I waited a long time to get this phone and now I might have to send it back

The AC charger is bad. No wonder for a 400 bucks phone they'll go after the cheapest brand they could to get us 3.0 chargers. Plugged it into my car this morning and it worked. Can I used the fast charger off my s7 edge? The input Is the same the output is obviously higher because it's 3.0 and Samsung one is 2.0. Will ZTE send a replacement charger? Or will I have to buy another. Says on the manual I can't use 3rd party charges too long or I can damage battery, guessing 20-40 cycles. Do I have to purchase another?

you can use any charger you want, but a Dash Charger from Oneplus because it's proprietary.
I personally use an Auckey QuickCharge 3.0 charger and it works great: https://www.amazon.com/AUKEY-Quick-...2-spons&keywords=aukey+quick+charge+3.0&psc=1
and the portable one too.

Ok .. wait... you like the phone ... the phone is perfectly ok ... it has a bad 5 dollar charger so you are going to send back the phone and buy a different lesser quality phone for higher price and .. well .. you may get a faulty charger on that one too .. or maybe even a faulty phone.... why take the chance .. just have ZTE replace the charger since the phone isn't defective. You do realize that you can charge it without QC and it is actually better because no matter what ZTE or anyone says .. QC will kill your battery faster than normal charging so QC should only be used if you need a quick boost and not to charge your phone on a regular basis. .. just use the little adapter they give you and your computer or an old charger you have laying around from your old phone and have ZTE send you a replacement for the bad charger you got.
When things are mass produced there is always a chance for a faulty component... and since the faulty component was the charger not the phone .. it seems kind of a foolish move to replace the phone if you "like it" .. I guess you don't really like the phone if having a charger go bad makes you want to switch out phones.

I'll just use my fd s7 edge till. I will be returning this device. It should work great out the box. No problems I will not buy another charger just so it won't work with this phone either. No AC charger works. Not to mention Wi-Fi has less range. Like I said I like this phone but I mostly like it for its sound. Wont keep it just because it sounds awesome when the battery wont charge. Not even going to deal with this sht I'll just get with a company I know makes quality products. Samsung never failed me, HTC either. Good luck guys.

Quick charging produces more heat than standard charging ... heat is what kills the battery. I have done more research and found that the heat caused by QC 3 isn't as bad as it used to be with prior fast charging methods and shouldn't really cause too much degradation of the battery. So if you are one of the people who replace their phone every year or maybe every 2 years .. then I guess QC3 isn't too bad.
If you are like me though, who doesn't replace their phone every year ... then QC3 may impact you if you use it for every charge. LOL .. my last phone before got the Axon 7 for replacement was a Samsung Galaxy S3 ... lol so I keep my phones for a long time .. The only reason I actually replaced the S3 was because I finally dropped it and broke the glass on the screen.

lol no offense but Samsung never failed you ???? you are lucky .. you bought a S7 edge instead of a Note.... Samsung .. a huge company failed a lot of people. But its obvious .. you are pissed off because a mass produced part went bad ... you are pissed because you had bad luck and got one of the bad chargers out of the 100000 chargers sent out. ... You act like the charger that came with it is the only way it can be charged and the phone is a paperweight because of this one small glitch that happens all the time and there is no way to control it.
No company can test every component they sell before it goes out the door... that would cost way too much and raise the price on the components way too much to be useful to anyone. As Samsung proves ... even big companies can have problems. Yes you got a bad charger .. just have ZTE replaced it .. im sure they would replace it without any problems at all. Until you get the replacement use either the cord from the Axon charger and plug that into your computer to charge it .. or use the adapter supplied with a charger that has a micro usb and charge it that way...
At least ZTE will deal with your problem ... I mean I have a Corsair AX760i Power supply .. it was over 200 dollars .. and supposed to be amazing quality .. well .. guess what .. it has a design flaw ... yet they still sell it even tho it has a known design flaw... they just don't care... at least with this ZTE .. its just a mass production issue.... its just a bad luck issue. .... they aren't selling defective products .... you just happened to get one out of thousands that prematurely failed and that happens to every product.

OK. So I've tried to use my s7 edge charger with it and it didn't work. Ironically it works with the car charger and it says AC charging but the phone displays a message to use the included charger for faster results. I come back from break and it don't work on AC, so in all honesty I would like to keep this phone but I think it's a defective unit. Not just the charger. So I'll contact ZTE to get a replacement because the phone is 4 days old. I will have more problems with a device like this if they can't do that I'll just get my money back. Thanks for your comments

Ironically it works with the car charger and it says AC charging but the phone displays a message to use the included charger for faster results. I come back from break and it don't work on AC, so in all honesty I would like to keep this phone but I think it's a defective unit. Not just the charger. So I'll contact ZTE to get a replacement because the phone is 4 days old. I will have more problems with a device like this if they can't do that I'll just get my money back. Thanks for your comments

yeah it may be an issue with the phone then .. I can plug my phone into my computer using the cord supplied with the original charger and it charges fine through my computer .. I can take my Samsung S3 basic non QC charger and plug it in with the adapter they supplied to convert it from micro to c and it will charge.. yes not fast but it will charge.
I would try plugging it into the computer and see if it will charge ... maybe the QC2 charger from Samsung just isn't compatible with the phone. .. for testing purposes tho .. i would try what I mentioned above .. using the computer with the supplied cord .. or using a basic micro usb charger with the adapter they supplied with the phone and see if it would charge... I guess if the only charger you have is the Samsung QC2 one .. I would try the computer with the supplied cord. I'm lucky I have a bunch of basic chargers lying around and they work to charge the phone without any problems .. yes its not quick charge but it still charges the phone.
If it wont charge when plugged into the computer ... or with a basic non QC charger and using the adapter to change from micro to c, then it may be something in the phone too ... but again ... these things happen with all mass produced products ... if you even have to do a full exchange ... hopefully you wont have bad luck with the replacement. My phone was fine out of the box ... as is with many others who bought it .. but ... again with all mass produced products ... it is always a crap shoot .... you can never say that each and every person is going to get a fully working product. Again to guarantee that they would have to test each phone and charger before packaging it and selling it.... and that would take many man hours and a lot of bucks so if they were to do that ... this phone would cost probably about 4000 dollars instead of 400.

I have to say I've had this phone now for a couple of months and I've had the s7 edge and s6 edge before that. I don't see the need for rooting the phones since i got the s6 edge onwards. The phones perform well out the box. But on all the Samsung's I've had from the original s series then the note series... There would be some sort of lag somewhere.... Though the Samsung's have improved recently... Still there is lag every now and then. This Chinese version Axon 7 i have is just totally lag free. It's on stock I've not done anything with it and it's working perfect out the box. I've got 2 sim and a 64gb sd card in it giving me a grand total of 188gb with dual sim. What can i say..... If they invest in some other features for the software... This phone can take over the smartphone market in a big way.

I'll just use my fd s7 edge till. I will be returning this device. It should work great out the box. No problems I will not buy another charger just so it won't work with this phone either. No AC charger works. Not to mention Wi-Fi has less range. Like I said I like this phone but I mostly like it for its sound. Wont keep it just because it sounds awesome when the battery wont charge. Not even going to deal with this sht I'll just get with a company I know makes quality products. Samsung never failed me, HTC either. Good luck guys.

WiFi less range??
My WiFi is so fast at home, it's really amazing:

Coming from the HTC M8, the only difference that I noticed in wifi performance between the M8 and this phone is that the A7 takes twice as long as the M8 when connecting to a wifi source. When I say longer, mind you, I am only talking about ten seconds or so vs less than five for the M8. So, still not bad and totally acceptable. Once connected, the connection stays solid though. I am really happy with this phone. It is better than the M8 in every way. Beautiful design(esp. the front compared to the M8), newer and faster processor, bigger and better display, 4K recording, fingerprint sensor, USB-C, QC 3.0, dual SIM/microSD up to 256GB, Tmobile Band 12 support and, of course, the awesome audio/speakers. All that for almost $300 less than what I paid for the M8. This is without a doubt one of the best values in the high-end smartphone market right now. A premium phone but without a premium price.

What was the charging temperature? I think over 44°C it shuts off. I sometimes have big lags when I download or stream stuff while charging. I had two other devices so far, this newer device has a larger actual battery capacity than the previous one but has this heating behavior. I think this is due to having different voltage settings to ensure larger battery capacity since it is still directly correlated. The other device didn't have this issue and felt more fluid overall but battery was depleting a little bit faster.
It may be that your device has too aggressive voltage settings and it stops charging because of overheating. But it is strange that it happens while you don't use the device at all.
Can you install accubattery and check your charging stats, estimated battery capacity, temperature, etc.?

I received mine a few days ago and it won't enter quick charge and I have to jiggle the charge cable to keep it connected. Tried multiple chargers and cables. ZTE tells me it's a bad charge port or battery. Too bad it's a great phone otherwise. It will have to go back though. 15 hours to charge from 0 is not helpful.

I am. Sure replacement will be great. I had 4 devices and they were all great, so you were just unlucky. Compares to other brands I had before, quality has been very consistent from device to device.

Thanks. Sadly, though, it started out great, but then started suffering from the same issue as the first. It's not quite taking 15 hours to charge, life the first, but a solid eight or nine. Also, there is the additional bonus of white flashing horizontal lines every so often, until I restart the phone.
I wonder if B&H got a bad batch. I noticed two other people, in different forums that got there's from B&H, had the exact same charge issue. Strange.
I've been living with it, until I can get a LeEco to play with, then it's getting RMAed. Hopefully the third will be the charm!

Which version have you been using? This is something strange. Do you think B&H may be sending returned faulty devices to their customers? You seem to be amongst a tiny minority of people who have issues - such a level of faultiness cannot exist for any manufacturer, it just contradicts the principles of manufacturing smartphones.

First I had a gold A2017U. Then a silver one. I have also heard some people that bought from Best Buy and had strange issues. I can tell you both got a big shipment in right before Thanksgiving. I almost didn't buy the phone because they were both out. The suddenly that week they both had them in stock. As a side note the tech support person at ZTE mentioned he had a few people with similar problems and was going to swap it out without hesitation. Instead I just returned it to B&H for a new one.
My tinfoil hat theory, and I have a background in manufacturing as an engineer, is that they cranked up production to meet holiday demand and didn't pay as close attention to QC (ie what parts their suppliers were providing). But I have no idea. It's just heresy and anecdotes from people. ::shrug::

I should mention, I still love the phone, and have no I'll will towards ZTE. It's an amazing bargain, and the best no contract phone I've had, aside from the issues. I looking forward to getting a replacement.

Op5 won't charge past 70%

The past couple months I have had some charging issues with my phone. The first few times it just didn't want to recognize the charger or would only slow charge. A couple times cleaning the port helped. Then it seemed like the cord might be the problem so I ordered a new OEM one. The problem has gotten worse and happens the same with the brand new charger.
The last few days it will fast charge to 70% and then stop charging altogether. I can't get it to take any more than 70%. I had the accubattery app which had a feature to stop the charging at a preset value to prevent wear of the battery. I only used this for a little bit and turned it off. Then I uninstalled the app in case a glitch was causing it to keep stopping the charge.
I have a new OEM battery ready to install if the battery is indeed faulty but even starting at 70% I can't kill the phone in a day so I'm not rushing to replace the battery yet. I'm just not sure that is the problem.
The phone is not rooted and is completely stock. It hasn't been wiped or anything since I bought it new over a year ago. Anyone have any ideas?

Update: I powered off the phone when it was refusing to charge at all and it was down to 56 percent. While powered off it charged all the way up to 100% no problem and since doing that it will charge without problems. Seems like this fixed it.

Update: the problem is still there. Still not charging above 70% while turned on. Not sure if the battery is failing or if it's a software issue.

Does anyone know of any other forums people might be discussing issues with the OnePlus 5? This forum is looking quiet these days and/or people aren't having a lot of hardware issues with this phone (hopefully).

The op5 forum isn't quiet. If nobody has an idea or any possible solution for you, you won't receive an answer. Seems you're the only one who has this sort of problem.
If you have warranty, just claim it. That's the easier way. Cause when it's the logic board or parts of it, it can be expensive.

It's already over a year old so no more warranty. I'm just going to try replacing the battery when I get a chance. If that doesn't work I'll try a new charging port (already tried a new charger).

Have you tried using the Ampere app? It does not make any magic, but it can give you and idea of what the problem may be.

Yes I installed it the other day and discovered when I was plugged in above 70% it was actually charging but very slowly. But this isn't always the case because when I first discovered the problem I kept waking up with a phone at 70% that had been plugged in all night.
I'm not sure how long ago this started because I typically try to charge it in the morning after my alarm goes off since dash charging is so fast. Eventually I noticed it never getting above 70% so I plugged it in overnight and still didn't get over 70%.
Accubattery says my battery is now 82% healthy. Despite not being able to charge above 70 I can still get a heavy days usage or a couple easy days. So maybe the lost health in my battery came completely off the top of the displayed percentage of my battery?
Occasionally it seemed like my phone wouldn't charge at all no matter what the percentage so the problem could be worse, but I may also be dealing with a worn out 1 year old charger cable and a new one I got a month ago that is defective because when I couldn't charge at all with the new one the old one charged fine. So I'm still trying to figure this out.

i am facing the same issue, i keep plugging the charger in and out till it works ... don't know why

Now that I've gone back to the original charger it seems to be making it to 100% every time and no longer seems to stop at 70 but if I move the phone a little while plugged in it sometimes stops dash charging and starts slow charging. Before when I heard it stop charging and start charging again randomly while I was in bed (it makes that little sound when dash charging starts) it was sitting on the floor unmoved.
So I think my possibilities are 1) 2 bad chargers
2) 1 bad charger and a bad charging port
3) bad charging port
4) bad battery + 1 or more bad chargers.
Or any other combinations of those problems. I think I'm dealing with 2 issues and that's why I can't figure it out.
