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.

I just bought an use xl. The oem accesories were never used seems he was charging the pixel mostly in his car. Now im using the official oem charger and cable and heat up the phone like crazy. It does say rapid charging but even the time went up to 3 hour estimated time to fully charge which is crazy. Now using a galaxy s7 edge dock charge and some spare usb c cable i had the phone does not heat up,. Charge in quick charge and it take like an hour and 20 minute to fully charge..... Im i missing something here?
Charging time left is not static it changes with temperature. If your phone is already reached 42 45 degrees which generally correct it slows down charging. And also it heats up if you are using your phone during fast charging intervals which is first 20 min. Also even when you don't use it, it heats up because of wake locks (charging). Also i realize a hot climate is a factor. For oem charger it can reach 3 amps so it is normal for heating and most other chargers supply less so it does not heat up. Soo it is like a design problem you can charge your phone super fast but it will heat up so charging speed will vary but i think in the end it will still quick enough.
Why do you think they advertise quick burst charge instead of quick full charge ?
Hello!
Charging problems started to occur a month ago on my phone. The problem is that it charges really slowly, but other times normally.
I experienced that if I plug in the phone when the battery is between 20-60% it charges super slowly.
Sometimes it speeds up but more often not.
Here are some screenshots that show that sometimes it takes like 6 hours to charge and sometimes it basically just hovers around a percentage and doesnt do anything. Gets like 10% overnight.
On the second picture you can see that it charges normally till it reaches 55% then it slows down to like 5%/hour speed.
I noticed this while the phone was draining battery even tho it was plugged in while using it.
I bought a new OEM battery and its the same with it aswell. Some chargers charge it quicker, some slower, but the problem occurs with every charger.
What do you guys recommend me to do?
Thanks a lot!
is your charger 2 Ampere as it should be?
U can also try to recalibrate the battery deleting the data/system/batterystats.bin file

Thanks for the reply!
I have used many chargers since I have this problem, but mostly the one that came in the box.
Ill try deleting that file if its possible withouth root.
Edit: It seems i need root for it, so its not an option for me.

Actually brother initially same problem occured with me and it was persisting on the same way load since i come to change my charger now before i was charging it with blackberry passport charger it was really cool and even charges it faster that i mean around 50% faster than the previous charger, but now days m befitted with moto g4+ which meets to charge my lg g3 around 65% faster
But brother dont use any local company pr anypther charger as it may damage the phone display which may come to cost you at high
There are going to be 3 main factors that you want to address:
- Battery
- Charger/charging cable
- Software
It seems you have already addressed your battery. That's usually the #1 culprit, but you've already replaced it so you can rule that out.
The next is the charger and charging cable. This is often overlooked. The stock charger is 5 volts and 1.8 amps (5v 1.8a). Before more advanced smart phones were developed, almost all USB chargers never produced more than a 5v 1.0a charge (most were 5v 0.5a). So you want to ensure you are using at least a 5v 1.8a charger. (I even use my Fire Tablet charger on my G3 which is 5.1v 2.2a, and that works great too). Note that all USB chargers have their output volts/amps printed on them somewhere (usually in very tiny print). The USB cable you are using matters too. The thinner the wire gauge and the longer the cable is, the less power is transmitted. For example, if you're using a thin and cheap 6 foot (2 meter) USB cable on a 5v 2.0a charger, you may only be getting 1.0a of charge from it. If you use a thicker, shorter, and more expensive 3 foot (1 meter) USB cable on that same charger, you ensure you get that full 2.0a of charge (or close to it). The two factors to look for in a USB cable is length (length = resistance = less amps) and wire gauge (not insulation thickness).
The last is software. If you have any way to backup and restore (ie nandroid) your ROM from recovery, I recommend doing that first because it's easy. If you backup your current ROM, factory reset, and the issue persists then you know its the charger/cable. If the issue is gone, then you know it's something in your current ROM. If you do not have access to backup/restore features and/or do not have root, then next you can use the Android OS Battery stats to carefully go over what could possibly be draining so much power when the phone is on or off. There are also several apps that will help you determine where the battery drain is coming from. Note that software can not prevent your phone from charging, but it can drain power so fast, that there is not enough left over to charge the battery. This is especially bad for our G3s because they easily overheat if they are charging and heavily discharging simultaneously.
Hope that helps! Good luck! :fingers-crossed:
Hi, I have Samsung Galaxy S20+ G985F/DS (Exynos). Few weeks ago I get a new company car, which has wireless Smartlink+ for android auto and apple car play. I was used to use cable, but few days ago I decided to bought wireless charger (Baseus Cobble 15W) to my car. Since then I have problem with overheating my phone when I am using wireless android auto and wirelessly charging it. I am using Spotify and Waze together and at same time I am charging it with wireless charger, but after few minutes (usually 5-10 minutes) it disconnets with error that my phone is too hot and it will continue charging after it will be colder. When I try to take a phone its damn hot. Is this normal behaviour or my phone is broken?
Running the battery hot will cause premature aging fast; stop doing it.
Software may be using a lot of cpu cycles; wayward apk(s).
Correct this if so.
It's not a good idea to charge and use the phone.
Get a fast charger for the car; you get about 2% per minute with a 25 watt one in fast charging mode between 40-65%.
A 25% charge should last 2 hours.
Li's love frequent partial midrange charge cycles and will get hundreds to thousands more full charge cycles when used like this. Partial fast charging does no harm as long as you keep the temp in the 80-99F range.
Try to avoid charging when under 80F and especially if near or below freezing temperatures.
Been using my 10+ like that for over a year, the battery is in very good condition to spite near all day use.

Well thank you for your answer, but I don't understand you well. Your post is very confusing. But from what I understand, you simply tell me, that I must buy normal wire charger and I must stop using wireless charger because using it is not good? But that is not answer that i want. Because I don't want to plug cable to phone, because when I have wireless android auto in my car, its useless. For example my colleague have car with built in wireless charger. And from what you told me, he can't use this built in charger because its bad?
You have two issues.
App(s) that are using excessive battery.
Charging while using.
Both are best avoided and both drive up the temperature.
Of course you can do what you want but battery longevity may take a hit in doing so.
Karma Firewall is useful for finding unnecessary bandwidth hogs and some of the battery hogs. Start with that.
All wireless chargers make phone hot. Even if you use it at home and no aps are open.

Excellent point.
A damp rag can be used to reduce the temp.
Unless the charge port is broken wireless charging just doesn't seem like a good modility.
Even at high frequency and optimum primary/secondary winding gapping air core transformers are notoriously inefficient.
These batteries are power hungry critters...
Man, I know what you all are saying but imagine covering your phone with a damp rag when changing, imma die of laughter if I see that anywhere. I know it's gonna work but it's going to be funny af
Mine did the same thing, it was 5 days old when I saw it the first time. If you insist using your phone and charging it wirelessly disable the fast wireless charging option from the settings and you are going to be good to go, but don't expect the phone to charge that much, maybe 2% in 5min, something like that probably. It will not overheat, tested it myself. Be careful, if it continues to overheat even with fast wireless charging option disabled stop using the charger when using your phone. I have a suspicion I burned my coil like that, it only took 5 or so times where my phone said that it can't continue charging because too hot. I hope that wasn't the case.
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
