Slower charge with 2A charger than car charger.

So for the past 2 days my Note 2 has been charging extremely slow with the factory charger. I get maybe a 5-6% charge per hour when plugged in at home but on my way to school this morning, I plugged it into my car charger and it charged 7% in about 25 minutes. Is it my charger or my phone? When I noticed slow charge I rebooted phone and left it over night without opening anything

Well, since I purchased my Note 2, I kept facing this slow charging problem. Now what is slow charging some of you will ask? Well, it's simple. The device is taking more than normal time for charging. Now how do you know the default/should be rate for charging? Simple again. The AC adapter clearly says output rate as 2000 mA or 2.0 A. So with that calculation Note 2's monstrous 3100 mAh should be fully charged with 2 hours. But as we've seen steady 2.0A is not the output case in some/many scenario, so add another 30 mins to it. So whatever it is, from 0-100%, the device shouldn't take more than 2 hours 30 minutes.
And for me, it was taking around 5 hours! Sometimes 4 hours 30 minutes, and if it's very fast then 4 hours. Well I was never gonna wait 4 damn hours before going to my office and irritate myself, and I don't have the habit of charging overnight, unless I absolutely need it.
So I kept calling my retailer, asked for replacement, and they did, well, you won't believe, they replaced three times actually, so I had three different Note 2, with three different charger. Well, each of them acted absolutely fine at first 3-4 charge, then the problem was back again and again. I in fact turned off the device and put it into trash once.
Then I thought let's try some different USB cables, I tried my friend's Galaxy Ace cable. Charging current kept fluctuating between 1000-1200 mA. Which was better than those faulty stock cables, which provided steady 900 mA. Sometimes it even was detecting the AC current as USB, which would provide a mere 460 mA and would take God knows how long! Then I found my piece. I went to my retailer, frustrated and angry, asked them to give me the thickest and shortest possible cable, and they provide me one from a Samsung phone's box, but I can't recall which device was that! And then I sat there for half an hour, kept plugging and unplugging, and the current rate was rock steady at 1800 mA. I took it, paid just 10$ and came back.
Since then I have charged my phone almost 10 times and the current rate never went below 1800 mA / 1.8 A.
This is the cable I am using, do notice that it has 5 pin set up against stock cable's 4 pi, if that matters in any way, and it's about 10% thicker than the stock cable and also about 9" shorter.
And how will you monitor the charging current, three ways are there,
1- Battery Monitor (yet I don't know how to exactly use it)
2- If you are rooted (which is a must anyway), then just go to, /sys/class/power_supply/battery/current_avg
3- Use the app from the link below. It basically reads the current value just exactly as above but it saves the time to go into that file every time. A big thanks to Deadvirus.

[Q] Tab Pro 8.4 (stock, unrooted) not charging properly. Worked fine for months.

Did anybody get issues months after they'd purchased the device?
My 8.4 Pro worked perfectly (6-8h SoT, 100% charge everytime) for about 2 months, but hasn't been charging properly since yesterday. I tried combos of all my charger/cables - they are all giving 1A+ rate on my other devices, but not even being measured on the tab (vis Ampere). Battery has been stuck around 50% for ages. I'm in India, so no easy way to get this back to the US for warranty replacement. Besides, by the time I return to NJ, the tab will be out of warranty.
Please note that I have also factory reset it. The problem, unfortunately, persists.
What should I do? This may not be a software issue: I use this tab while I'm on a stationary cycle, so maybe that motion somehow 'knocked' the battery out of whack somehow? Should I open up the tab and do a battery reset? Is there any, less dangerous, solution?

You need to use a 2A rated charger and really there is only a few that qualify, I suggest you only use the Samsung charger as they seem to have a certain way to charge it, chargers do go bad sometimes so look for an official replacement (they cost like $5 on ebay), beware of knockoffs though since they look identical, I suggest searching for the same model number on the charger. IE : EP-TA10JWE
anyways here are some things to try in the meantime
1. drain the battery down to 15%
2. hold the power button down and choose the Power Off setting, wait until you feel it vibrate, now let the tablet sit for an hour in this state. (do not hook it to a charger)
3. after an hour or two, plug the charging cable into the table and let it charge (do not turn it on), you should see an animated battery screen show up a few times, see if it reaches 100% in this "powered off" state.
if it does then that could mean there is an app running in the BG when it is started causing a lot of cpu load or keeping it awake..
I've so far had my tab 8.4 for almost a year and the battery is still holding up with 8-10h of runtime (depending on what I do). and it always charges to 100% using the samsung charger.

The chargers I tested were rated 2A, and their cables were 28/24 AWG. On my Dell Tablet, the same setup was giving me around 1300 mah. On the pro, most of the time the current didn't even get measured.
Tried the other things you mentioned. It charges, overnight, to 100%, but despite the factory reset, weird battery behaviour is observed: slow recharge, jumping from 93% to 100% the moment i connected it to the lappy to transfer data, etc.

You are using the Samsung charger?, I noticed with other chargers for some reason when the battery gets near full the mA drops to under 200mA and stops charging the battery or its just enough to keep the tablet running, this does not happen with the Samsung charger it mostly charges the tablet at 1880~mA, when its in the 90% range drops to about 600-800mA so it can still trickle charge the batt and provide enough power to keep it running.
I have tried other chargers like the 2A HP Touchpad Charger (was supposed to be the best charger out) and some 2A powerbanks - and they all fall short near 90%, just don't pull enough amps, I think the samsung charger has a higher voltage too 5.60v where the others are around 5.30v
btw I have an actual hardware mA cable that shows the current in realtime, I'm not sure how accurate the battery monitor programs are for android without root access, since without root I don't know how they read the system files.

Getting a slow current with the 5.3v samsung charger and cable as well. But yeah, using software (GSM battery, Ampere) to get the charge.

Hm I suppose the battery could of went bad if it wasn't being charged properly by some chargers for example if it was never reaching 100% then the system never shuts off the charging mechanism and will essentially cook the battery causing it to die faster then normal .
If you had root access you could check the status of the battery and it would report the battery info in stages - very good (brand new), good, bad, fail ..etc I am not sure if non root programs can access this info.
I guess there are a few extra things to try.
1. A new Samsung charger, it might be possible yours went bad.
2. re-seat the battery, though this requires opening the tablet possibly voiding the warranty or causing other damage - maybe take it to a repair shop if you have difficulties, from what I have read on this forum it has solved numerous cases like yours, not sure exactly what it does perhaps removing voltage from the hardware causes and glitches to reset like from accidental static electricity shocks or if it just re-calibrates the battery like it was replaced..etc, it might just be the connector comes loose, anyways it sucks Samsung didn't included a reset button since it's a needed feature for sealed tablets)

This is a fairly common issue on this device. Its a defect, I'm thinking its the "smart battery" circuitry on the battery itself (my understanding, at least some of the metering is done on the battery by this circuitry). Its been discussed at length on the following thread; with the suggested fix being to open up the tablet and "reseat" the battery: http://forum.xda-developers.com/galaxy-tab-pro-12-10-8/general/reseating-battery-wonder-battery-life-t2944610
I've had this problem for a while now. The issue was non-existent or rare at first, then got more common after owning the device for a few months. Haven't used any apps to measure the mA, but this is across 3 or 4 different chargers, 2 of which are original Samsung 2A chargers (had another one left from my broken Note 8). The issue also persists whether on stock ROM, custom TouchWiz ROM, or custom AOSP ROMs.
Sometimes the tablet will charge fully, no issue. Sometimes it will stop somewhere along the way (well short of 100%) and doing a reboot will usually get the charging "going" again. Sometimes I will need to reboot 3 or 4 times to get it charged to 100%. I've also tried factory resets, but its hard to say whether this helps or not.
Short of rebooting while charging, there isn't much I've found to help. I haven't tried opening the device to reseat the battery.

Maybe the usb port in the tablet has some debri in it. Try blowing it out with some cpompressed air. The symtoms sound like a faulty usb cable but if you have tried different ones it might be the port.

Slow Charging Issues

For the past few days, I've noticed very slow charging on my Pixel even if it says "Charging Rapidly". However it would say it will take around 3 hours to fully charge. When fast charging works, usually clocks at 1 hour and 30 minutes.
I really don't know what can be causing the issue. It's the original charger, and cable. Normally removing the cable and putting it again would fix the issue but it's becoming a common thing for it to take 3 hours.
I remember a similar issue on my Nexus 9 and cleaning the cache would completely fix the issue, but the Pixel XL is missing the Wipe Cache option in the recovery.
Any similar experiences?

On the OEM included charger?

Yup.

Could try a factory reset.. probably the only software related solution. I can't remember, but Chainfire may have said that the cache.img was one of the things that got removed in 7.1 so I don't even know if you could wipe it if you wanted to. You could also hit up Google support... maybe they'll send you a new charger to try. Make sure you're using the OEM cable too, at least for now, until you figure it out.

I had this exact issue with mine, factory reset / charging in safe mode didn't work.
Turned out to be a faulty usb cable but Google insisted on replacing the entire package (handset etc) Replacement works fine

Well, thanks for the heads up! What sucks though is that it's type C to type C, I have some Type C to regular USB, I guess I'd have to buy one.

If it makes you feel any better, Google exchange process is amazing.
Raised the return on mine about 4pm and the replacement was on my desk 9am the next morning, they also give you 14 days to send your old one back so you're it without a phone.

I use ampere to see what the charging rate is and I don't feel like the fast charge is that fast.... My 6p charged at a faster rate and my pixel charges at a faster rate using my Choetech smart charger. I'm going to have to drain the battery and see how long it takes to fully charge with the stock charger

When I checked mine it was charging at something like 2600-2800 but i only watched it for a few minutes, might have gone higher

Some phones ie lg v10 do not "fast charge" while screen is on (while youre looking at it) to avoid overheating. Ampere cant show max charging rate. I use a usb sleeve (usb doctor) that displays that info or turn on notification display
EDIT: Supposedly Pixel do not fast charge while in use either.

I think I can confirm this. Last night mine showed 27 minutes to charge from about 50% but after keeping the screen awake for about 30 seconds, it went up to 51 minutes.

I also find my Pixel charges very slow as well even though it says Charging Rapidly (OEM charger, cable). The GSM Arena review said they went from 0% to 46% in 30 minutes, I get more like half of that at most. I used Ampere and it said i was only charging at 710 mA.....

If you charge it from almost empty it charges very quick, but slows down once it gets nearer to full

Yes i started charging my phone when it was 4%, and when i looked at it about 20 minutes later it was only at 16%. I think it took about 3 hours to fully charge. The only modification I've made to the phone is unlock the Verizon bootloader and flash the P software (which was subsequently updated to V). I'm seriously wondering if the charger or cable is defective.

Quick Charging Power Adapater

Since the 17th every night when I charge the phone it makes a very low humming noise and its at its louldest when the between is low. at 25% if become a little better and after 40-50% its not so noticable however I just wanted to check if this is normal as i am getting mixed views from Razer Support.
Is it normal for the charging block to make this humming noise?

I've got the same issue. I have posted all the details on my other post check it out. I think razer have flopped with these wall chargers and/or usb c cable. Its not quick charging although it states rapid charging and having gone through two wall chargers already, first one was quiet and this new one i have has that humming noise your on about.

I've got 2 phones, neither charger hums, 0-50% in about 30-40 mins, 50-90% in about 40 mins, 90-100% 30 mins. 0-100 takes about an hour and 50 mins. (well, it was at 4% to start)

That's fine I'm glad it wasn't just me being that fussy guy I've read online it's not much to worry about as I had a coiling graphics card which made the same sort of hum but eventually that went away or I got 1-2 months older and my hearing couldn't pick it up anymore.
Razer have now said they will send me a replacement charger out to test and will give me a self address package to return the charger - so let me keep the one that works better.
Shipping from HK they still want it back to make sure I'm not claiming a free charger from them.

I finally got the replacement charger from them which did fix the problem i was having with the noise coming from the charger block.

I also received the replacement charger, seems to fix the noise issue. However I am yet to understand the Quick Charge on this phone. It says charging rapidly but it definitely does not charge rapidly. Charging at 1900mA throughout is not quick charge technology.

Got some more info here:

apart from the noise issue i had with the original charger the charging time itself im failry happy with along with the all day battery life even with a little gaming and netflix/youtube streaming.

Odd. I plugged my phone in at 15% when I got the warning, and I am looking at it now and its fully charged. I want to say it wasn't even a full hour but... I confess I didn't look at the clock.

A70 "Super fast charging" ! Really ?

Hi guys,
For those having the A70, does the "Super Fast Charging" feature work for you ?
With the original provided charger (with the "Super Fast Charging" logo on it), I need 3 hours to go from 9% to 100%.
So that is 1% every 2 minutes...
I do not consider this a "Super fast". I think it is "Decent" but would not go above that...
For me, this a severe disappointment... Unless of course I am doing something wrong
Anyone else can share his results for Super fast charging here ?
Regards.

Your phone must have an error. Mine lasts about 1:20 to charge from about 15% to 100%.

Hi,
Thanks a lot for your answer.
The phone... or the charger maybe ?
Is there something to enable to have that "Super Fast Charging" ?
Or something to not disable ?
If I can solve battery drain (not really lasting as I expect) and this, I will think again about keeping the phone.
So far, it's more a non keeper

Hello . Do you charge it with the screen closed? Only then fast charging works! IF yes then something is wrong with either the cable or the charger .You could also try a factory reset !

Hi,
Thanks for the info => Super Fast Charging only with display off ?
So if I leave "Always On" it will not work ?
Maybe that is why...
Anyways, I did as you suggested : I have done a full factory reset, and I have installed the bare minimum of Apps.
We will see about battery drain an battery charging.
I'll keep you posted.

Hi Sufyan3D,
Thanks a lot for that info...
I've made sure that the fast charge is enabled.
So far, the device is still at 100% so I can't say if the problem is "solved", but I'll make sure to report if now it charges as it should
And also about battery drain...
Regards.

That's correct! OK check it now and tell us! No battery drain, this thing is a beast! Keep us posted!

Hi,
So far, I cannot tell about the Fast charge.
But the phone is almost idle (really gently used) with "Always on" enabled.
It's been idle since about 3hours and battery is at 98%.
I consider this a rather good result.
Hope it'll stay as it is once I install all my apps...
If not, I'll try to track the culprit for the high battery drain.
Regards.

I have same problem, after reading your post, I drained my battery to 9% and charge, it so slow while charging.

Hi guys,
Well I think it is confirmed that my phone has a problem.
The battery drain is more than acceptable.
I drove my kid to school yesterday. It is a 80 minute trip to go there and come back.
While I drove her, I used the A70 as a GPS whilst it was connected to car audio with Bluetooth.
Battery drain in 80 minutes was a little less than 10% which is quite good I think...
Then I played a bit with the phone and went to bed.
This morning it still had 84% battery.
So that is about 2% battery drain overnight.
Not stellar but acceptable.
So I decided to hook it up.
The battery panel reports "Fast charging plugged in".
But after 40 minutes, I am still at 98% charge.
That means 40 minutes to get 10% battery.
I am aware that the last 10% are the longest, but still... 40 minutes for 10% ?
I will test with another charger to see if it is the phone or the charger...
Regards.

Download a free app called "Ampere" from the Play Store, to measure your charging current. Plug the phone into the charger then open the App to get the measurements. Post your result here and compare with other A70 owners.
App shows that my charging current is around 1100mah (with the 25w charger)

I landed here as I was surprised how slow my A70 was to charge. It takes around 3 hours to get from 15% to full, using the included Samsung 3A charger & original cable. Ampere shows the current trickling in at around 850mA. Super Fast Charging is enabled. My previous phone was a Xiaomi Mi 8 Lite which charged at around 2A according to Ampere.
PS I found this link which suggests most of the fast charging happens early in the cycle https://www.sammobile.com/2019/05/02/how-fast-is-samsung-25w-super-fast-charging

The Charger is rated at max 2.77 amps and 9 volts for fast charging. It will vary through the charging cycle though. Towards the end, above 80%, the charging will slow. How long does it take from 15% to 80% and what is the measurement in the middle of that?

Will need to measure that the next time I charge it as it's now at 100%! How long does yours take from 15 to 80%?

I've never tested it. I have fast charge turned off. I charge my phone over night. The battery lasts me all day every day.

Samsung A70 Failed!!
I think A70 is failed in all fields.
No porper GCam. And now batteries.
My device getting charged in around 4 hours with original cable and charger.
Now I think I invest 27k in wrong item. OnePlus 7 or realme 3 pro was far better than A70.
It's just name Samsung, nothing else. Blank box with tag of Samsung. Really disappointing with this.
Sorry to fans of Samsung devices. But I don't like this. After 2011 (Samsung Galaxy Y s5360), I think Samsung is better nowadays but I was wrong. I will never buy Samsung phone again.

I am not facing such issues in my device. Regarding development, for a device like a70, development is always slow. We have the source codes available. The only thing missing is developers onboarding to support the device. If at least 1 dev puts the kernel and device source codes and tree in github, I bet development will start soon after.

I took some readings with Ampere during a charge:
0 mins 8% battery 4050mA
30 mins 38% battery 1060mA
60 mins 52% battery 1050mA
90 mins 66% battery 1020mA
120 mins 81% battery 1080mA
150 mins 91% battery 1000mA
180 mins 100% battery
So 3h from nearly empty to full which is not exactly fast. Is this in line with what others get?
