So I just ordered this charger and it charged my phone from 4% to %100 percent in exactly 3 hours!
http://www.amazon.com/gp/product/B0051ZJA64/ref=oh_o00_s00_i00_details
Wow, what a great improvement over stock which takes 6+ hours. This makes me believe, that even though the stock output is rated at 1000ma and this charger's output is only rated 700ma that this charges works correctly!
If you have a 1800mah battery and you charge it at a rate of .7A, it should take it exactly 2.57 hours to charge, (1800/700). With stock it should take less, because 1800/1000 = 1.8 hours, but it takes 6+ hours to fully charge! Something is f'ed up with the stock charger or phone's software...
Yeah. About that. I just got my E4GT yesterday and noticed it does charge extra slow compared to my O.G. Epic.
My wife stayed with hers, maybe I will try charging my phone on hers. I wonder if that would make a difference...

At first my charging was extremely slow but now it'll charge from 2 to 100 in under three hours

I use the Palm charger from my TouchPad. Will go from dead to fully charged in about an hour and a half.
What's you TouchPad charger's output in mah? I think I might have to splice into a spare USB cable and check how much current is actually used by phone when on stock charger...pretty sure it is nowhere close to 1000mah.
2000mah is the output from the TP charger.
According to BatteryMonitorWidget, it estimates avg mA charging at 270mA using the stock charger that came with this particular phone.
I have my original charger from my Evo 4g and have noticed that it charges my phone a lot faster then the stock one that came with the phone. :-( weird

That sounds about right! I'll see if I can test this with my AMP meter tonight and tell you all for sure on stock vs new samsung charger that I've got.

Yeah, at 2000mah it should charge in less than one hour...I would say your actual charge current to be around 1200mah...
i would be careful with these chargers.
i have dealt with a lot of Li-Po's in the past and there was a formula to how fast you should charge them.
i imagine it is the same deal with Li-On.
charging outside such formula could kill the life of your battery or worse.
Seems like i must have gotten lucky as a ton of people are having problems with their phone or chargers.
I just charged my battery from 0 to 100% off the stock charger in 2 and a half hours and i also havent gotten any of the dodgy input problems using the phone while charging.
I went back and took a longer look at the battery history when charging. When starting the charge at 65% it starts off around 828mA, then 540mA, then 360mA, so it looks like (as expected) the phone knows how much current to pull to charge the battery safely and it adjusts based on how full the battery is. Not saying it does this for the charger included with your phone, but that is the behavior for the charger included with this phone.
These are all estimates provided by Battery Monitor Widget because there is no real-time mA current meter in this phone (according to the author)
Ordered one of these. Stock charger takes a lifetime to charge the phone.
My GF got Nexus S 4G and it's stock charger also takes 6+ hours to charge, so there's something wrong with the chargers I guess...
The pins on this charger must me different than the stock charger. Just because the stock charger is rated up to 1Ah doesn't meant the phone or batteries circuitry allows that much output. The resistance and length of the USB pins on the cable are what determines the output of the charger. Simply using a different USB cable with the stock charger will get you faster charge times.
Using a 2Ah charger will get you nowhere, the circuitry doesn't allow that strong of a current. Just a bit of an FYI. Save your money and save your phone, use a different USB cable.
Also, how is the charge time holding up? I doubt you're getting a saturated charge with that charger.

Ive dealt with 1,2, and 3 cell lipos ranging from 150mah to 5000mah, and every one of them either say to be (or ive been told its recommended to do so) charged at 1C. so a 500mah battery should be charged at .5A, 1000mah at 1A, 5000mah at 5A, etc...
my lipo charger displays a bunch of info as the battery charges and it definitely drops the current as the battery gets closer to being fully charged. if its the same with li-on then I would imagine that .18A should be the most you would charge this battery, but Id rather it take a long time because unless things have changed recently, doesnt the slower you charge the battery prolong its life cycle as well as extend how long it lasts each charge? I only charge mine at night when I am sleeping so who cares if it takes longer than an hour. if I get into an emergency situation I have the cig lighter charger and in the worst case I even have one of those crank flashlights I can use to charge the phone in the event my car battery shorted out or something...
I'm curious if anyone has been using Qi charging with their TabPro? Anyone's comments would be appreciated.
I used a micro-usb Qi coil receiver between my TabPro 8.4 and the Poetic case for a few weeks without issues.
But then something happened to cause the Qi charging pad to overheat. I ended up having to have the TabPro 8.4 replaced by BestBuy as the TabPro would no longer charge at all, even trying different micro-usb cables and 2.1 amp power adaptors. What was even stranger, was the battery continued to drain even after powering the TabPro off! I'm puzzled as to what was damaged, but the end result was the battery went from 41% charge to 7% charge overnight even though it was powered off (not sleeping, but powered off) and not connected to a charger. When I discovered it was at 7% I removed my account info, but even with the charger plugged in, the battery went down to 3% while working on the TabPro. When I checked on it an hour latter it was dead. If I plugged in the charger, after about 20 seconds it would flash the green battery for about a second, then it would go out. No boot, no charging, even after leaving it charging for 24 hours.
So I'm very reluctant to try to use Qi wireless charging on my replacement tab. I suspect the Qi charging pad failed and overheated. There is a spot about the size of a dime where the plastic partially melted on the charging pad. The Poetic case and the TabPro look fine, and the charging pad still acts like it is working. Very puzzling. Any ideas or cautions?

The only thing I can think of is maybe the Qi charging pad failed to deliver 2.1 Amps to correctly charge it (I don't think they even make 1 Amp coils yet? - though I could be wrong.) , maybe the tab went into charging mode but it was really discharging since not enough current was going in that it needed to charge + keep the tablet running so in the end maybe it destroyed the battery since it went completely flat which is usually a bad thing for l-ion battery's
Usually when android says the battery is at 0% the battery really has about 20% remaining for protection of the battery and preventing it from going completely empty (l-ion can really be drained to 2.5v but android reads 0% around 3.4v or 3.2v if i remember correctly as protection from flat-lining the batt), however if it was under charging mode I'm sure it would override this as it thinks it's plugged in so it's not paying attention to the battery, but really the batt is draining to compensate for the underpowered charger, that would be my guess maybe constantly using the Qi charger the battery circuitry changed the battery status from lv 2 (good) to ~ lv 4 (bad) since it wasn't receiving the current it was supposed to and the circuitry thought something was wrong with the battery cells or the battery just went bad since it was always under a charging / discharging state never reaching 100%.
on a side note
I found this tablet to be very fussy when using other chargers then its official one, I have tried several chargers and they just dont function like the stock one for example
HP Touchpad charger 5.3v - 2.0A - Very high quality charger and even won some awards for beating out other chargers - I found this would sometimes not fully charge the tablet to 100% it would idle around 98% (I have two of these chargers) - Charge current starts around 1800 mAh drops to 200 mAh when battery gets full don't think its enough to top it off. (charges at 5v)
10,000 mAh Power-bank (5v , 2.0A), found out this would not fully charge the tablet either it would get to 80%, upon further inspection the 2A port was only delivering about 1 Amp of current according to my amp reader (voltage drop to 4.98)
Samsung official charger (5.3v 2.0A)- though seems to start at a pretty high 5.60 volts (higher then other chargers) , and charges at about 1870 mAh , always reaches 100% with this charger. (I have two of these chargers since I bought another one as backup - both do the same thing)

That could be the case. Yet, for two weeks, the Qi charging had no problems taking the charge to 100%. It would charge a bit over 15% an hour. The Galaxy Charging Current app reported between 670 and 750ma charging current using Qi charging.
At this point I'll likely never know, but it could be the battery itself simply failed on the tablet. My question is mainly to see if anyone else has used Qi charging, and what their experience is. How can I display the battery status (you referenced lv 2 (good) to ~ lv 4 (bad))? The battery app from the Play Store does display "battery health" but I've only seen it say "Good".
On your side note, I occasionally plug the tablet into the USB port on my computer (measures 5.10V), and it charges at about 10% an hour while sleeping, and has repeatedly charged the battery to 100% when I leave it connected. I have an EnrePlex Jumper Prime 4400mAh that measures 5.18V, and charges at 1.5A. It has charged the battery to 100%, though will run out of juice if the battery is lower than 40% before I use it, it measures 5.18V.
I have an old Galaxy Tab 2 10.1 that I often charge via the computer's USB port, although it takes a long time, and it's battery is still fine after almost 3 years.

The battery app from the play store probably does the same thing just shows a status as a replacement of the health, you can see the status with logcat occasionally you will see something like this ---
you might need root for some of these commands., you can use Terminal Emulator , adb shell, or sshd to access these commands.
Logcat::
1.
"D/BatteryService( 934): level:83, scale:100, status:3, health:2, present:true, voltage: 4091, temperature: 234, technology: Li-ion, AC powered:false, USB powered:false, Wireless powered:false, icon:17303447, invalid charger:0, online:1, current avg:-378, charge type:0, power sharing:false"
2. (shell)
dumpsys battery
will output something like this
Current Battery Service state:
AC powered: false
USB powered: false
Wireless powered: false
status: 3 < - unplugged
health: 2 <- health:2 would translate to good , health 1 would be excellent (though I have never seen a 1 status , 3 poor, 4 bad
present: true
level: 83
scale: 100
voltage: 4114
current now: -140
temperature: 248

Hi.
I have owned my SM-T700 for about a year now and its a beautiful tablet! But after updating my firmware to 5.0.2, i have had a problem that really messes up my time with the tablet.
My tablet has slow charging. Like extremely slow. After the update, it usually took around 9 hours to charge completely when at around 30% of battery. Now when I charge it, It only charges around 5% per hour!
I used the app called Amperes to measure my charging rate and it was at 750mA but then dropped to 30mA. I tried resolving the issue by switching to 4.4.2 but I cannot find the XAC version of it unfortunately. Also,
I am not using the samsung charger that came with the device, I am using the samsung charger for my broken s3 but it says that they take in the same amount of mA. I also tried with my cousins tab s charger to no avail.
Thanks! I would be grateful for any help!
Are you using original or hi-quality cables with a real 2.0 amp charger?
I've a Tab S 10.5 LTE updated to Lollipop from the first day I bought it, so I'm not sure if the charging speed differs from KitKat.
When using the original 2.0 amp charger and cable I've noticed that the charge is slower while I'm activelly using the tablet, but that means about 12% hour rate.
If I try with another Samsung charger rated at 0.7 amp it can recharge the tablet slowly and only when it's idle, or just slow down the battery discharge if I'm activelly using the tablet.
I consider this normal, as the tablet can easily surpass 1 amp discharge rate when the display, cpu, radios are all busy.
To get full charge rate of 1800mah , I normally see 1500mah/1600mah you need to use the original Samsung 5.3v 2amp charger and original cable as a lot of third-party charger will only charge slowly as the Tab S cannot recognize the charger is powerful enough, so it only uses a slow charge so not to damage the charger, even with the original charger after the battery reaches 80% fast charge stops and it is normal for the charger to use lower and lower ma as it reaches 100%
John.
Just put 13 stable on my phone and charging my phone Takes forever I mean it's slow as hell..Wasn't the best on Android 12 but hell on Android 12 it was way faster.. That's the one thing I hate about this phone the battery life sucks an charging the battery is so damn slow..I got all the Adaptive crap turned off.
I'll have to pay more attention to the charging speed on my P6P and let you know what I experience. I try to never use fast charging, never charge overnight, try not to let the battery go below 25% and don't charge past 75%. That 50% range lasts me about 24 hours, but I might use my phone less than you.
I had no complaints about the charging speed on Android 12.
Edit: I'm happy with how much my phone has charged in the last 45 minutes, given that I don't use fast charge methods.
I am having the same issue. Installed 13 stable on my 6 pro. My battery got down to 4% so I plugged it in. I continued to watch YouTube and after an hour it was only up to 8%. Something is def wrong. The battery sucked before but now it's even worse
Updated yesterday and seems ive now got an issue with wireless charging. My phone stopped charging at 81% overnight. Its very intermittent whether it starts charging now on the two wireless chargers i have and seems to stop randomly, not getting to 100%. Charges fine using a cable.
Have the same problem since upgrading to android 13.
According to AccuBattery is the charge current around 900 mA. Way too slow and really annoying!
Didn't have the problem with android 12.
I'm using an Anker Power Port III which can charge with up to 25W. It's the same with other cables and charging devices.
Edit: Attached some screenshots
To clarify one thing for a number of users, you will not get adequate charging speeds without the official charging cable, the 30W Google branded wall brick and good temperature conditions.
The temperature conditions are generally the hardest to control whilst using the device - so I always charge with my phone powered off and have never had an issue. Heck, I generally charge with a 5W wireless pad and it always reaches 100% overnight (usually takes about 5 hours with my minimal wattage charging pad).
*Edit*
In the end - with the official cable usage - my charging speed hasn't changed between A12 and A13.

I think you didn't get my point. I did a comparison between android 12 and android 13. Since the charging speed is reduced dramatically it doesn't matter which cables or charging devices I use unless they are the same.
So we don't discuss absolute charging times here but the fact that by upgrading the OS of our Pixel 6 Pro the charging behaviour changed ceteris paribus.
I charge slowly over night, the charger i use normally charges at 1.5A max, now on A13 it is charging at 800mA
I have ESR magsafe ring. My car charger is working for about 2 minutes and stops. Battery temperature reach 43°C within 2-3 minutes since I upgraded to android 13.
All of the magsafe accessories stopped working. All of the normal QI chargers stopped working. I absolutely hate this phone. First 3 months - no reception in buildings. Still no 5G in my country even with root and signal guru. Now it's not charging wirelessly and only slow charing with cable.
My new guess is it is due to the overheating problem with the update to Android 13.
A lot of people complain about the high temperature. Therefore the phone reduces the charging speed.
Maybe that's also the reason for the problem with the wireless charging. too much heat = no wireless charging. Just guessing...
ATM I rebooted my phone to safe mode. Let's see if this helps.
Somehow I solved the problem. I booted into safe mode. Then I clean the temp files with Google Files. And now my phone is charging with 2mA and above again. Also the temp of the battery is down to 36°. I still think that is the root cause.

well we know for one you dont need that
just a cable capable of the current and a charger that hits PPF standards
and even with/without official chargers it will only peak 21w
im using a £5 Gan charger and a USlion 2M long magnetic 60w cable that can do data aswell and it is doing 20w peak for me on A13 which is what it did on A12 aswell. Both which i bought before the official charger came out

Nope, still charging like a piece of [crap, so,] not sure what Google did with A13 , I use official charger for fast charge, considerably slower than on A12
But yeah 3rd party Chinese charge and magnetic cable no issues. Charging issues are not a13 related it will be some defining factor like an app or hardware

I am having the same problem
I updated my pixel 5a to 13 stable. It's charging speed decreased a lot . Firstly it took around 1hr 50 min to get 100 now it's lot
more than 3hr. Gets lot of heating while charging.
Sometime it shows "6 hr to full charge" even at (30-40) battery level, and that's really bad .
After 13 Device is heating ( not just warm) so much even in normal uses (No gaming).
My own testing found out as long as battery reach 41 degree C, the P6P will charge at 3.5W only... (While still displaying fast charging). It you put the phone in front of air conditioner vent to lower the temperature to 25 degrees C, then it charging at full 20W.
The P6P easily get into battery y 41 degrees C by just charging at room temperature higher then 32 degrees C. On A12 its pretty difficult to get this... Somehow A13 drive the CPU while charging which I suspect affect the heat dispatching. I used a charging wire with watterage display so its easily see how P6P limiting the charging wattage with temperature.
It was considerably slower for me too. I was in Spain, coming from UK, so had to use adapter. I thought it's the case, but it has also been something with temperatures, I couldn't backup the pictures because the system showed me it's too hot. I hope that was the issue.
I just swith to Android 13 there are ossue with battery . please fix it .you guys are doing great work
Hello!
I have been using RM8P for the past 2 weeks and everything was fine, the 65W EU adapter charged it really fast, however today I noticed something. I noticed that when I plug in the adapter to charge, the Maxcharge logo appears and the percentage displayer starts to rise fast, however after 1-2 seconds it slows down to normal charging speed, like if it was only a 20-30W adapter.
Why? How can I fix it? Restarting the phone did not help. I am on the latest OS for EU (3.19) .
Maxcharge logo is displayed but the speed drastically descreased ...
I checked several times while charging and I noticed that sometimes it speeds up and sometimes it slows down... why? Why is it fluctuating ?
What is the battery level when you plug in? My understanding of charging tech is that it is not always full speed from min to max. If you're sometimes plugging in above that throttle level it may go slower.
Then again, I'm not 100% on new charging tech. My RM8 has yet to arrive.
In my experience, it's not the phone but the charger. With my old op9pro it happened more than once, the charger started failing, you could get another 65w rated charger and check with accubattery the power delivered by both chargers. Down here they shipped the phone with the eu charger and a standard American charger rated "65” the eu Nubia charger goes to 64/ 65 watts without issues (I use an adapter to connect it) , the bundled one even though is rated 65 only gives 45w, sometimes 39, which is a bit annoying but it doesn't bother me, as long as I can charge it while having a shower or when I'm having breakfast before taking off, it does the trick, this thing is so good, battery lasts me 2 days
