Hi,
My wife's S5 mini seems to have developed a nasty habit of not even fully charging overnight.
When using a USB powermeter, I see the current fluctuating between (roughly) 200 and 800mA. Other devices on the same multiport USB charger have no such issues, so it is not the charger.
When using the OEM charger and lead it will also charge very slow, to the point where it may not even be full the next morning.
I downloaded the Galaxy charging app (very informative on my S4), but it always shows 1mA chargingcurrent, so I assume it does not work on the S5 mini.
I cleaned the USB-port on the phone and removed some lint, but no difference.
Wiggling the micro-USB-plug makes no difference, nor do different charging cables.
We switched the phone OFF and removed and reseated the battery: the problem persists.
What I did NOT yet do is swap the battery (we have two same-age S5 mini's in the house and only one has the issue). If I can pry the second one from my daughters hands, I will try this and report back. Obviously if the problem moves with the battery, it is the battery. If not, it's the phone. Or if the problem is gone, then it is just those darn Gremlins again.
What I also did not do is boot into safe mode (or whatever is sometimes adviced) as the phone does not go through its battery fasst, it just charges very slow. An inefficient app would also not explain the fluctuating currentdraw (certainly not it dropping below 500mA when battery is 80% empty), so atm I don't consider an app to be a likely culprit.
Any ideas are welcomed.
Ideas:
1. Install and use the free app Ampere to check both cable and charger;
2. Turn phone off and plug in charger, even off it shows the percent charged, so you can check if it's system software problem or not.
Check if the micro usb port is dirty. You can't imagine how much dirt can get there, specially fibers from clothes. Normally I use a needle to clean it, maybe there is something more appropiate.
Got the same problem after 3months use.
To avoid this problem:
1- Plug the charger
2- After 5 seconds connect micro-usb into the phone
If you connect first the phone to the charger it will not charge properly

hi, new member here.
bought my tilt on 10/4/07. has been flawless since that time.
used the nav quite a bit during a road trip, used a cig lighter usb charger.
got home and my battery was at roughly 40%.
put it on the charger at night went to sleep. in morning disconnected it at 8 am. shortly after i arrived at work i got the critical battery low chime. checked and it had like 7% battery life.
figured i didnt plug it in right, or it got knocked loose some how and didnt get charged.
put it in flight mode to minimize battery usage. left work at 2 30 pm (4% battery life) and put it on the car charger. got home and put it on the HTC supplied wall charger. light turned amber, so i assumed it was charging.
checked an hour later and turned phone on, it said 0%, and immediately died. left it on the charger for a few hours and the light was still amber, turned it back on and again 0% and phone immediately died and did a soft reset on its own. i turned the phone off and left it on the ac charger, took out the sim card and put it in an old blackberry to use while the battery was charging.
its been on the ac wall charger for the last several hours, i checked and the phone is totally dead, cannot turn it on, and the LED at the top is now RED.
what is the problem here? why wont this thing charge?
thanks in advance, i have alot of critical info on this device and any help would be greatly appreciated.
i cannot hard reset because i cannot turn the flippign thing on....
Does it charge when you connect it to your computer? If it does, then your charger is toast. If not, then it's probably the phone itself.
I'd try a different charger first. If that makes no difference then a different battery. If that still does not make any difference then time to exchange it.

connected to either the computer or the wall charger, the LED thats normally amber when charging, and green when charged, remains red.
I had something very similar happen to my wizard.
And as weird as it sounds, the only fix was to charge the battery in a friends wizard on his charger. I'd check the battery if possible.
Could be the battery. Know any place or anyone that will let you try a charged battery? If not, you might have to go in to an AT&T store.
i think i got it working. did some reading/browsing...
took a usb wire and cut the mini usb head off. dissected it and found the the red and black charging wires. took out the battery and held the leads to teh battery while the other end was plugged into a USB/AC adapter wall charger from a old blackberry. after manually charging the battery for several minutes, i put the battery back in the phone and the phone started up. now it seems to be charging off the wall charger and the led is now amber from red.
thanks for all your help/suggestions.
well it worked briefly. the amber light has gone back to red and it seems that the battery is not charging.
dont know what happened to my perfectly functioning phone.

Repeat this proceedure but this time do not turn the phone on, just plug it in to the wall charger once you have zapped the battery again.
Turning your phone on probably just caused the already recovering battery to die whiles it is trying to take on a charge.
It is mentioned quite a lot on the boards that Li-Ion Batteries do not like being over disscharged and there is usually a little protection circuit in the battery to provent complete disscharging although this circuit may be on board the phone. Completely disscharging a Li-Ion cell will kill it stone dead and it will need replacing.
When you took the battery out and so called jump started it with your flying leads, this possibly reset the little protection circuit in the battery so it can now take on a charge. I feel that once you turned on the phone, this was to much for the already depleted cell to take and possibly re-tripped its inbuilt circuit.
If you do manage to recover you cell, in future it is good practice not to let the battery go below about 25%. Li-ion cells are generally happy being top off regularly.
I hope this helps buddy
Do let us know!
Cheers

thanks, that was very helpful.
ive tried defibrillating this battery out of the dead several more times to no avail.
ill try it one more time when i get home from work, if its a no go i will go to teh att core store. the phone is 6 weeks old, dont know what they can do for me if the battery is toast...
That Sucks! I hope they'll give you a new battery.

I had exactly the same problem with my battery. It came on though after a day. Although the battery life after this happened went down to 10hrs max on standby. I sent the phone back and got a new one and now all is fine.
This is a problem that affects almost all makes of phone. There are three (main) causes of the problem:
1.
The battery charge drops too low to allow the charging circuit to recognise a battery is even in place (red no charge light stays lit)
possible solution:
http://forum.xda-developers.com/show...22&postcount=6
(in the end very similar in the end to the USB wire used in post above)
2.
A faulty battery (but if you can charge it using a cut usb cable or using a couple of AA batteries this may not be a faulty battery.
3.
A faulty charger OR a charger not delivering 5v at 1000mA as the OEM one does. Many chargers that are used for other phones or generic chargers only deliver 500mA. This is not enough when your battery drops very low. (these chargers are OK for occasional use but I do not advise using them regularly particularly if the no-charge syndrome has shown itself)
4.
A faulty USB connection on the phone. I have now seen a couple of reports where the fine wire connections in the phones USB port have become bent out of place.
Number 4 above is at least possible for the OP as it seems the battery will charge using a cut USB cable but not when either the PC USB cable or mains charger is connected. A USB port on the phone with a a bent internal contact would explain what's happening.
A previous poster was able with a needle or similar to bend the contact back into place.

i had the same problem with my phone.
put it in the charger overnight and woke up in the morning and couldnt turn on the phone with blinking red light. I don't know if my battery was over-drained though. I went to AT&T and was playing around with their charger and new battery and somehow the so-called dead battery started working again. They changed the SIM card on my phone there and then i haven't been able to use the phone since. I've changed the network to GSM instead of Auto setting under Phone Options which allows us to make calls; but now I can't connect to 3G network.
Charging thru mini usb
My phone started to exhibit similar problems...plugged in but no charging of the battery. I finally realized that my mini usb connection on the phone has been compromised (bent, distorted=not functioning properly) Now I have to prop the mini usb connection up at a slight angle to engage the charge. I think the plastic/metallic connector on the phone is somewhat fragile ...I had similar issues with my hermes.
called customer support.
they are sending me a new phone and battery.
how do i know its not a refurbished one? any clues?
before u send out your defect phone, have u check if your phone's mini-USB connector has bent or misaligned pins?
yeah all the connectors visually are fine.
Without knowing what it was, I encountered the RLOD on my phone after leaving it on USB overnight. After reading the first two or three pages of two different threads I tried the little lucky "fixes" and found that none of them worked.
I have a backup phone and need my phone for work, so I put my SIM in that phone only to find it was dead. Went to my local AT&T store and they said the SIM is fried. They replaced the SIM and everything is working now.
I replaced the battery in my TyTN and now I'm recharging my original battery. The phone works without problems, or heating up, or shortened battery life.
So here is my theory:
The phone has a similar monitor as the offgrid solar system does. It's job is two-fold: don't let the battery overcharge -and- don't let the battery every discharge to 0.
I suspect that most problems may happen when the phone is connected to a laptop or desktop computer via the USB port and left on when the computer goes to sleep. At this point, the scenario is similar to a monitor on an offgrid solar home. The monitor decides when to pull from the batteries and when to fire up a generator. But if the monitor is set incorrectly, it constantly flicks between charge/generator and the end result is a huge draw on the batteries (rather than a charge going into the battery).
Now with the laptop asleep the trickle charge is way lower than normal. Activity on the phone may also actually flick the laptop in and out of sleep mode. The basic end result is the phone starts the same type of draw between battery and trickle charge, causing a higher than normal draw on batteries, and finally it heats up the chip on the SIM and fries it either partially or completely.
If you have "resuscitated" your phone, but still have problems, simply replacing the SIM should fix it. If you get the RLOD I'd say get the SIM replaced as it is fried. Once you get the SIM and any SDHC card out, very tentatively try to recharge the old battery on the wall charger. (In other words, don't take your hand off the charger when you plug it into the wall) If you get a yellow light, breath easy. If you get the red light, UNPLUG IMMEDIATELY and throw that battery away!
My research on offgrid solar has been going on for almost a year and I began this theory when I noticed a few things:
1) I saw posts from people with not just HTC phones getting a red light.
2) I saw a few posts where people mentioned they used the USB overnight.
3) I have seen firsthand what the constant toggling can do to a 24V 1500 kilowatt hour battery system and the heat it generates.
Except...
There is no USB power when a laptop is shut down except for a few newer models which are designed intentionally to do so. And USB activity does not wake the laptop, particularly not "in and out" of sleep mode. If it does, your laptop has problems.
Final point.. Hasn't it been ground in to use the supplied charger? Most people who report failures admit they were using third-party chargers.
That said, a USB cable should be a more reliable charge source than a cheap AC charger due to the fact that a laptop has to have clean power itself and cheap AC chargers can fail in many fashions and often result in excessive DC voltage or AC voltage winding up in the source.
Hi,
I have a new and flawless Note, the USB connector is OK.
At night I connect the Note to the charger and I put some music on to fall asleep. Playback is configured to just play one album once.
Normally I put the phone in Flight Mode, in order to sleep without unnecessary radiation next to me.
On some few occations (it happend to me for like 5 times now), in the morning, the phone is not charged at all! But I am 100% sure that the battery status icon on the top bar signaled the charging mode.
This morning it happend again and I noticed that I left the Flight Mode off (because my wife is away and I want to stay in contact if needed).
Also, I noticed that I have been using a ZTE charger specked with 750mA, while the original Samsung Galaxy Note charger is rated 1000mA.
Can it be, that I was using the ZTE charger on its limit and that having apps running, or maintaining flight mode off, was enough to actually not being able to deliver that extra juice to charge the battery?
The other reason could perhaps be a software problem, like some app draining the battery as much as the charger is able to charge, so in the end the battery stays more or less the same.
I am positive that the USB port is not broken. I.E. I tested by unplugging and plugging the charger from the wall socket instead from the phone and all is recognized OK. Also, no issues when connecting to the PC.
What is odd: on previous occations I think I remember that I just plugged the phone back and it charged.
I swapped the chargers, but still I have this odd impression, fearing that the device might have an issue.
Anyone had similar problems?
Cheers,
vma
Yes, looks like a weak USB charge problem. You get similar behaviour if you try to charge the device from a PC - sometimes I have mine plugged in to my PC at work all day and it barely charges. Get home, put the official charger from Samsung in from a walk socket and it charges in an hour or two max.

So... Yesterday my battery decided to drain really fast. Checked the mA and it was -1137 and when I plug in my charger it decreases still to-500 or more than -2000. When im not using my phone the phone will charge about 5% per hour and stops charging at times. Leave it over noght and it might charge 10%. Same gies for when the phone is turned off and charging. So, is it the usb port or the battery.
The battery drains real fast. The port is clean and the board looks fine when i dissassemble. Usb cable holds tight, when i pull the connector part up then it disconnects.Used multipll cables, sockets, and chargers.

I've just posted my solutions to some very similar problems you've described. Not able to to post links but it should be easy to find, just search for [solution]usb port / charging issues.
Have you checked the two copper plates on the under side of the removable plastic unit just above the usb socket. Adjust / manipulating the connection there has solved my charging problems.
Hope this helps. I'm not an expert by a long shot, but if this is not the case, and you have replaced / renewed everything, then I at very least would recommend trying a new battery.

lately, somewhere after update to one ui 2.0 I started to have some problems with the fast charging.
as for now, the fast charging won't work unless it plugged to type C port in my PC that supporting QC3, and even that for like 1 minute max and that shorting my WHOLE pc's USB ports.
tried many bricks and cable supporting QC3 though the phone supports QC2, and nothing sadly made any change, tried as well on using the original brick and cable and still the same.
I've also been trying for like a week to clean the port with cotton and 70% alcohol and nothing changed
I tried to measure the Amps coming from the charger and got like 2 Amps max, although I remember when the Fast Charging did work, it gave like 3.3 Amps(all measured by ampere app)
I'm thinking it may be the port itself, but not sure about it
what do you think?
any help will be appreciated
Edit: I tried to wipe cache and charging in safe mode
Try wiping the Cache Partition in Recovery Mode.

This is a well known issue with all Samsung phones. They use the cheapest USB connectors on the market and they short out very easily. I lost fast charging over a year ago when my phone said the port was wet even though the phone had never been anywhere close to any water ever. The only way to get it back is to replace the USB port. With the phone being so old its not even worth the money to fix. Same ship happened to my wife's S9+ . I'm not buying another Samsung phone.
Thanks. I can see how a cheap port could be the problem. I've had this problem with my note 9 since day one. I can plug in a brand new cable that works great with somebody else's phone into a Samsung charger and randomly it will max out at around 750 ma or 1040, 1425, or up to 2275. This is even when the phone is at less than 20 percent, and the phone is not warm at all. I have wondered if a faulty temperature sensor has been to blame.....
What's odd is that i can take it off a QC or Samsung charger, stick it on a battery pack and it hops right up to 1200. Got a temperature sensor app and all is around 120 degrees F which I'm pretty sure is normal.
Do Not use 70% isopropyl alcohol on electronics, it's 30% water
Only use anhydrous isopropyl ie 99%
Use a OEM fast charging brick and cable. They're cheap, $20 for a Samsung 20w brick and cable.
Erratic fast charging and a rapid drop in battery capacity may indicate a battery failure.
Any case bulging is a battery failure; replace asap.
