Galaxy Nexus won't charge past 89%

Hey guys,
I've tried Googling this problem but haven't found any real info or a solution. I have a Verizon Galaxy Nexus with the official 210o mAh battery. For the life of me, I can't get it to charge anywhere close to 100%, not even 95%. It seems to stop right at 89%. I'll leave it on the charger at night and when I wake up, it's always showing 89%. If I go into the battery info , it will say 89% not charging. Is there any way I can get it to charge into the 90's? I'm sure it's not a software issue since I've seen this on AOKP b40 and M6 as well as Jelly Belly 3.4 and 3.9.

Wipe battery stats, re calibrate the battery, it could be a kernel problem, completly drain battery and recharge to full with phone turned off. These would be my course of actions. If all else fails maybe replace the battery.

Thanks. I've tried different kernels (faux, franco, trinity, lean) and I still see the problem. I haven't tried wiping battery stats/recalibrating since I've read it doesn't really do anything, but I guess it's worth a shot.

If this phone is anything like the SGS2 wiping stats does nothing.

It might be. I might put in the standard battery tonight, charge it up and see if it hits 100% (or as close as it will get to 100%) when I wake up in the morning.

You can't calibrate a battery and wiping stats does nothing...

try a different charger?

OK, so I'm seeing the same issue with the standard 1850 mAh battery. Stuck at 89% on the charger and the battery stats says "not charging" while it's on the charger. I've tried the standard Gnex OEM charger, my wife's SGS3 charger and my old Droid X charger and all say the same thing. So strange...

Maybe an issue with the connect port? Do you just rip the cord out?

No, of course not. Plus, if it was an issue with the micro USB connection, wouldn't it simply not charge altogether?

I had an old Droid X that wouldnt charge past a certain point but I could fully charge my battery in my girlfriends X with the same charger so i dunno

Tested on different phones
Here's my issue I got since I rooted and flashed JRO03C Jelly Bean Rom.
Since then I've tried many roms, battery calibration (that I learned, does nothing), tried many "fixes" like disabling everything while charging, realingning the usb pins...
The fact is that : My battery is actually charged 100%, but shows from 74% to 86% (depending on the rom).
If I take my battery and put it in another Galaxy Nexus that hasn't been rooted, it gets 100%.
If I take a 100% battery from that unrooted Galaxy Nexus and put it in mine, it shows only 74% to 86%.
Sometimes, the battery gains % while I use it (It's a 74% when It's not charging anymore, half an hour later it shows 76%)
I don't seem to have lost any life time, but here's the problem as I see it.
Either my phone cannot properly analyse de output of the battery, or there is sont slack connectors inside the phone that actually dont get 100% output from the battery.

Take it to Verizon, show them, and they will give you a replacement.

I'm having the same issue as the OP, my battery was fine until about a few weeks ago. Nothing changed as far as ROM or kernel go. I have the Seidio 3800 though. My phone just refuses to charge completely even when turned off and charging. The animation for charging that last little bit literally stays on forever. I left it on the charger for almost 8 hours after this really started to bug me, and upon turning it on I was greeted with 88% and it quickly dropped to the mid 70%'s where it floats out for a long while. This is my second battery from Seidio, the first didn't work with NFC and charged too 100% just fine. The OEM battery will no longer charge completely either.

Yeah, as relevant as your post is, no. My batteries have all been NFC capable, one was defective and didn't work. I don't even know why you posted all of that, the last two links weren't even relevant to your point. I think the whole NFC token thing is fooey anyway.
The issue at hand here is my battery life being miserable and reported very incorrectly for virtually no reason at all.

Relevant because it also has to do with chargers used if they don't have same voltage as original or it messes up the nfc. Just saying the batteries, phones, and chargers have to be the ones they can with. Also same info on Samsung site, fine print at bottom. Anyway, just trying to help because I had same problem and don't anymore.

I'm using the OEM charger and cable, always have.
Your first link goes to a Verizon image talking about a possible less than stellar experience with NFC on the Gnex with using other batteries. The second link talks about compatibility of batteries between the GSM and CDMA version of the Gnex. The last link isn't even about the Galaxy Nexus, it's the GSII. None of them mention chargers/voltages/messing up NFC.
Edit: Back to the task at hand, I was just wondering if the OP ever got his battery life figured out, or if he just replaced the thing.

[Q] Note 10.1 2014 charges very slowly

I just bought a new Note 10.1 2014 edition, everything works fine, except the battery takes 30 hours to charge to 100%!
The screen was off the entire time it was charging, but the device was still on, in airplane mode, with power saving mode on and the gps was off.
I'm using the stock samsung charger I got with it, but with a american-european converter, although I don't think that should matter, because on the box it said it could take over 10A, and the stock samsung charger is 2.0A.
The device doenst register the charger as a USB or anything, it realizes that it's charging via AC.
Is my cable, samsung charger or converter just dirty/broken? or is there something wrong with the device?
ps, I have Cleanrom 2.0 installed, and use some Gravity Box tweaks
Thanks

If you have the Snapdragon P605 , then this should take around 3-4 hours for full charge from 0%, while Exynos processors P600/601 normally takes 5-6 hours charge time.
So probably you have a defected or malfunctioning charger or cable , try charging without the converter & see if the case is still the same , then that will be either a faulty cable or charger.

It does if you have a P-605 with Qualcomm's QuickCharge feature. See the pretty little stylized "A" in the upper left corner of the graphic I posted? It's the AnandTech logo. They don't lie and have been performing objective standardized tests on mobile devices longer than you've been an XDA member (2007). If my choice is believing their 7 hours and your "4-5 hours tops" guess who I and most people here are going to believe? And my P-601 does take about 7 hours to charge which is a hella long time especially when you're traveling.

LOL, I'm literally timing mine as I type this - I will report back the exact time it takes from 5% to 100% - Using the standard wire and socket Samsung provided. Curios if people timed their devices if they would all be the same time frame - I know my first tablet took something around 6hrs to fully charge will see what this one is like.

mine charges at 21-24% per hour up until 80% where the trickling starts. at that point it constantly takes 90 minutes to top it off. i doubt that anand lies, but he's only testing one sample and he's reporting what he gets from it. mine takes 4-5hrs depending on how frisky the tablet feels in taking some juice.
i don't have any logs so bmw pro but if i ever remember to let it drop down so i can get a long charge logged i try and post it.
it's not like any of us are gaining any internet fame by reporting a 5hr charge or getting any pay.
cables do affect the charge rate a lot. so if you get less than 5hrs then check another cable. this this is very pick on the cable for some reason.

mine takes 3-4 hours....its a p605 probably you have a defective piece or try another power outlet

Holy crap. Just like the Exynos/S-800 N3, the Exynos/S-800 N10.1-14's use different charging circuitry and get very different results. AnandTech tested an Exynos P-600. Like my Exynos P-601 it takes 7 hours to charge from 0-100%. People with S-800 N10.1-14's have been reporting getting a full charge in 5ish hours which is about the percentage difference between the two different N3's. You'll also notice the second runner up in longest charging time is the Exynos-based N10 which, like the N10.1-14, uses a microUSB port to charge. If you adjust for the smaller battery, the Exynos N10.1-12 with a 30pin connector charges about 20% faster than the N10.1-14 with a USB charging port. N10 owners that bought the optional pogo pin charging module have been able to shave about 30ish% off their charging time which means it's not the battery or SoC causing prolonged charging times via USB on the N10.1-14 and N10.
Conclusion?
The P-605 is one of the fastest (if not the fastest) large format tablets.
The P-600/1 are slugs which is probably as much due to microUSB as a charging port rather than what the battery/SoC can handle as evidenced by the N10's improved performance when using pogo pins.
P.S. - Here's the N10's charging graph (via USB) and it's pretty linear. So Samsung (who builds the N10) may have done something in terms of faster charging mid-charge for the N10.1-14 but if they have that power they certainly didn't apply it on the N10.

P.S.S. - P605 owners go away. "Slow charging" has nothing to do with you and you're just muddling the thread which admittedly should (re)titled "Exynos N10.1-14 Takes Forever to Charge."

Their belligerently calling people liars and making it seem that people posting different result are daft. If you can dish it out you should be able to take it. But seriously, this thread's very poorly named as it doesn't identify that only the P-600/1 are slow charging. I knew that from other discussions already had on this forum. So, while maybe a tad belligerent in their approach, people that didn't know there were differences between the Exynos and S-800 versions of the N10.1-14, could have assumed they were the same.
Here's the difference between a device using Qualcomm's P4981 dedicated charging module (QuickCharge) and a device using standard charging circuitry. Pretty impressive. Numbers below are for a 3,300mAh battery. And the dedicated charging circuit is what makes charging via USB mute on S-800 devices.

Okay here are my charging results which I have timed.
Started charging 16:20 @ 5% - https://www.dropbox.com/s/yeoup9hafrmw93q/Screenshot_2014-01-13-16-17-41.png
Finished charging @ 21:25 @ 100% - https://www.dropbox.com/s/gxmcpp0aq9od5l2/Screenshot_2014-01-13-21-24-28.png?m=
So charge time of 5 Hrs - like its been said, it charged very fast till 85% then slowed right right down!
Mind you I did not use the tablet at any point apart from lifting the book cover to see progress. Personally I think the charge times is alright.

Here's a little food for thought from the SGS4 forum. It doesn't matter if the device being tested is Exynos or Qualcomm since QuickCharge was introduced with S-800.
spark001uk said:
With the advent of the S4, and its higher capacity battery, one could understand a higher charging current. However, I seem to have uncovered some findings that the charging system on the S4 is a bit more complex than first thought!
This is a bit techy, and assumes you have a basic amount of electrical knowledge, ie voltages, currents, resistance etc., but I'll try and keep it as simple as possible for anyone who may not!
To explain: The mains charger supplied with the S4 is a model number ETA-U90UWE, rated 5V @ 2A. However, the phone will ONLY charge at full current (which as I have measured so far, depending on what the phone regulates it to, typically sits in the region of 1.2 - 1.5A), when using the supplied charger (or possibly one of equal or higher current rating, depending on how it's configured internally), AND the supplied usb cable, OR any other usb cable, provided its shielding (the metal outer surface of the connectors) is connected at BOTH ends of the cable. Use a cable that doesn't have this shielding, and the charge current drops, regardless of whether there is plenty of current available or not. Use a different charger with an unshielded cable and the current drops even more, again regardless of whether it can supply plenty more current.
My assumption on this, is possibly an effort by Samsung to avoid the scenario of sticking 1.5 amps down a flimsy cheapo cable, the wires of which will likely be too thin to carry it.
After doing some probing around with a meter, I have managed to find a slight difference with the charger itself, compared to a generic one. In a generic one, the two data pins are usually just shorted together, which tells most phones that it's a mains charger rather than a USB port. On the Samsung one on the other hand, the pins appear to be shorted together, and also connected via resistors across the supply line (known as a potential divider), which holds these shorted data pins at a certain voltage. This is what tells the phone what sort of charger it's connected to.
Attached are a couple of diagrams to show the difference between the two chargers. There are in fact various setups of resistors that different manufacturers use to set the charging current, so it's quite easy to run into compatibility issues!
To make this a little less confusing I have done some preliminary experimenting, and I set out my results here.
For the test, I used combinations of 4 different usb style mains chargers: an apple iPhone one rated at 1A, an iPad one rated 2.4A, an HTC 1A one, and the genuine S4 one. With these I used two cables - the supplied Samsung S4 one (which is shielded), and a cheap generic one (which isn't). I started by measured the charging current directly with a meter, by using a very short usb breakout lead I've made, enabling me to interrupt the 5V line. However, I soon noticed that the use of any extension cables, even shielded, can lessen the chance of maintaining a good shielding connection, so I continued the exercise relying on the "galaxy charging current" app to get a reading.
Charger.................... Cable................ Current (A)
=====================================
HTC 1A.................Generic..................... 0.5
HTC 1A.................Samsung S4..............1.0
Apple 1A...............Generic......................0.5
Apple 1A...............Samsung S4..............1.0
Apple 2.4A............Generic......................0.6
Apple 2.4A............Samsung S4..............1.3
Samsung S4.........Generic...................... 0.8
Samsung S4.........Samsung S4...............1.3
So as you can see from these results, the original charger makes a difference, and the supplied cable (or a good quality shielded one) makes a further difference. If you have any further findings please feel free to add them here.
I can see that this is going to confuse some people, as it has me, as I'm sure some will inevitably try charging up their phone on generic chargers/leads at some point, with potentially long charging times resulting!

http://forum.xda-developers.com/showthread.php?t=2274321

that's been my experience. i've gotta make sure that i have the right cable AND charger to get the full blast - using p600. the fastest charge comes from the stock charger and a car charger i have (powergen 2.1A). no charger has ever reached 2A and the highest i've ever seen is 1.6A.
regardless of the fact that one's tablet may charge a few hours faster than someone else's - five+ hours for a charge is waaaaaaayyyyy to freaking long! my samsung ativ 500t has about the same battery capacity but charges in 90min. the 700t charges in 2hrs. of course using 12V 3.3A charger is giving a lot more juice than a 2.3A 5V charger is, lol.
one thing i noticed is that occasionally, the trickle ( charging past 80%) would sometimes drop to 300MAh instead of the normal 600 to 900. if i catch it, i just unplug it and replug it and it's back to normal. dunno what causes this though.

[Q] Battery takes more than 6 hours to charge???

I have bought a brand new p-601, since the first installation it takes more than 6 hours in battery charging.
Is it normal or there is something wrong with the battery/tablet.
Is it possible reset the binary counter to 0, cause I have rooted it twice?

Yes its normal, all Exynos Note 10.1 2014 take a long time to charge, My P600 takes 5 hours however others have said it takes them 6-8hours to fully charge.

Same here
Think it's because of USB 2.0
Note 3 with USB 3.0 in roughly 2 hours
Someone could calculate the theoretical time by comparing how much power USB 2.0 can put through vs USB 3.0. Should be roughly 2 times more.
So maybe there will come a Note 10.1 Pro with USB 3.0 and NFC

It's not USB 3.0. Only the Tab/Pro 12.2's have USB 3.0 anyway. Here's how Samsung implements USB 3.0; at least on the N3.
The Galaxy Note 3 ships with USB 3.0, unfortunately at least in its current state it doesn't seem to get any benefit from the interface. Although the internal eMMC is capable of being read from at ~100MB/s, sustained transfers from the device over adb averaged around 30MB/s regardless of whether or not I connected the Note 3 to a USB 2.0 or 3.0 host.
Update: USB 3.0 does work on the Note 3, but only when connected to a Windows PC with USB 3.0. Doing so brings up a new option in the "USB Computer Connection" picker with USB 3.0 as an option. Ticking this alerts you that using USB 3.0 might interfere with calls and data, but then switches over. Connection transfer speed is indeed faster in this mode as well, like you'd expect. It only appears on Windows as well, my earlier attempts were on OS X where this popup option never appears.
Charging is an interesting story on the Note 3, but primarily because of what doesn’t change. The Note 3 continues to use Samsung’s tablet charging specification and charger, which has 2 amps of maximum output. The Note 3 draws 2 amps over a considerable amount of the charging curve, like other Samsung devices (in the linear part of the charge curve). USB 3.0 doesn’t change things up here quite yet with the new supported charge voltages that are coming eventually with the power delivery specification.

The p600 has a battery capacity that is 2.56 times bigger than the note 3 (3,200 vs. 8,220mAh) so its not a fair comparison.
.

My P605 My P600 takes 4 hours.. don't know about the exynos version.

It is obviously slower than any tablet or phone. Very boring and annoying. The question is how to differentiate between motherboard failure and normal slow battery charging?

Try a different cable
I was having this problem a few days back but found a hint on one of the threads I found on the internet. I was using a USB extension cable with the Samsung charger. It was taking 1 hr just to charge 1%. Then I tried not using the extension cable. It's now charging 10-15% every hour. It's likely the calbe you're using is the problem. If it's not the original cable that came with the tablet, try that cable.

I just got mine for xxxmas, and it takes about 6 hours, give or take, to go from ≈5-10% to full charge, maybe less when I don't use it; and I guess I get about the same life most have mentioned (is there a way to track charge/discharge times?).
That said, I just plugged in at 15%, and I just crossed 25% in about 20-25 minutes. I use the stock charger and cable plugged into an extension cord as thick as my arm... okay, my forefinger--hey, I like having a good extension cord that can carry the juice, the precious juice!

Thanks for your feed back. But I have tried this solution before and changed the cable with a good one.

P605 here, and yes, it's normal, . It takes even longer if you're using it while charging. My philosophy is: "I sleep, he charges". Not perfect though, due to the amount of time I sleep, not much.

So my P600 Note 10.1 normally takes 5 hours to charge from 5% to 100% and the last 20% usually trickles and takes 2 hours. I remember someone on xda mentioning to unplug and then plug back when it hits 80%, so that's what I did yesterday and it took a total of 4hrs10mins from 5% to 100%. No idea how it made it charge faster but hey it worked.
P.s I use stock cable and plug.

Mine Note SM-P605 takes 5 Hours to charge and doesnt matter if have it turning off charging. Shouldnt it suppose to be around 3 hours charging time with qualcomms quickcharge 2.0?
0-100% 5-6H
10-100% 5H
How do peoples manage to get around 3H charing time with LTE version?
Im using battery monitor widget to monitor the charging, from start its around 1600mah and from 80-90% it start to drop to 1500mah-1000mah. From 90-100% it tickles down with 100mah for each 1% charge.
Is this normal? Im using Samsungs charger that comes with the box with EU adapter plug, since its HK version I got and if it does matter.

@dt33 i guess the EU adapter plug is the cause of slow charging. P605 should not be taking 5hours.

Id doubt that EU adapter is causing it and also tried with 3 different adapter. Since they just make HK 3 stick plug to EU 2 plug and doesnt convert electricity.
If any have SM-P605 version and can confirm with battery monitor widget.With history stats, how much mA does it charge bewteen 0-100% and is it same as mine does?
With sceen of:
0-80% - 1600-1700mA
80-90% - 1500-1000mA
90-100% - 900-100mA for each 1% it reduce with 100mA.
Does Qualcomm tickels down charging from 80-100% as Exynos version does?

It isn't the charger or the cable, it's something to do with the battery. I've had two different units in the past week or so that have taken over 7 hours and sometimes the charging stops before it is full and the discharge varies so much from 3 hours to 10 hours with the same things open and this happens on different chargers. Samsung agreed that both units were faulty, so enough is enough, I'm going to try something else.

After reading here and elsewhere about the GN 2014 charging time, I checked mine this morning. I wanted to do that before my 15 day return is up at Bestbuy. Yesterday, I ran the GN 2014 until it came with a screen and said to connect to charger. I think it was about 3% left.. This morning I put it on the charger at 7am.. at about 11, it was almost full, I unplugged it, and then plugged it back up again, and at 12 noon it reported 100%..
I have read that at about 80% on charging, it is real slow, and to un plug and re plug at that time helps..Anyway, 5 hours to 100% is normal, so I am okay.

Thanks for u offering, but it doesnt matter now and Im tired of Samsung. Too many buggs and none fixes and theirs customers support is none existens.
Now I also got black screen, waking it up from sleep, touch stopped responding or superlag (whatever its), cant swipe between home screens bla bla and couldnt either click on oki to reboot the device. A long press on power button for reboot is only choice.
Also suddenly battery drain from 100% - 97% just in 3 min for scrolling around home screen, appdrawer, open apps.
This tab just have too many issues and not worth mine time or buy.
Today at work, mine friend told me that his Note 8 LTE that he bought for 2 months ago, have also screen shaking problem as its with Note 2014.WTF is this?
Waiting for 4.4 and see if it resolves any of the problems. Or else, I just sell this **** and forget about Samsung.

[Q] Battery Jumps from 42% to 100% while charging

My battery jumps from 42% to 100% while charging.
When i had first noticed this problem my battery used to jump from 75% to 100%.
but after trying numerous ways to calibrate the battery , everything resulted badly and now it jumps from 42% to 100%.
Please share your experience regarding such an issue and if u have figured out a way to fix this.

so many people facing that problem, we still don't know what cause it, is it software problem or hardware problem, but in my country (Indonesia) someone from Indonesian asus forum facing that problem and he brought his phone to ASUS service centre, he waited for about 1 week, and after he got his phone back asus had changed the motherboard and the battery, so I think battery jump is caused by hardware problem.... cmiiw

How long does it take for battery to jump from 42% to 100%? The 2.3GHz plus 4G ram (ZE551ML)" is bundled with 18W adapter which has quick charge. Please see the following link regarding quick charge: http://www.asus.com/us/support/FAQ/1011185

I had the same problem with an lg G2. If it jumps that much in a couple of seconds then it is really hardware, can be the charger but most of the time its the battery and internal power supply. You just had a bad luck, it can happen anytime to anyphone, Asus have excellent support. Contact them by phone.
p.s: Nice to see Asus staffs posting on xda.

from 0 to 42% it takes around 1 hour after that It jumps instantaneously. to 100%
Yeah i use 18W adapter.
I get battery backup of around 3-4 hours only.

My problem is different my problem is fast charging no working takes ages to charge says 2 odd hour charge or 1 hour 52 and it still takes ages plugged it in 2day 2 charge it said 7 hour I thought wtf anyone know how to help please

I cannot be 100% sure as it never happened to me with this phone but with my old g2 cellphone , it was hardware and I had to replace it. Your best bet is to call Asus by phone.
@kumarsaurav11, 0 to 42% should take much less than 1h. It should be 0 to 60% in ~38 min with that 18w charger. Same advice here.

Mine goes from 40 to 0, 3rd time in a row, brand new, just received it this morning, ZE550ML, if problem persists by the end of the week, I'll be returning it first thing this monday and getting a Mi 4i instead.

Mine is jumping from 78 to 100..
It charges to 60 like at quick charge and then after that it gets super slow..like takes hour+ to get to 78 or so..is purely software related cux in getting around 5-6 hours of sot similar to any user with no jump problem..hope it fixes tho
Plus its happening to half of the users that cant be all hw related..

We are mostly running 2.19.40.22. Never had it with my zenfone 2 4gb ZE551ML, I don't know about the 550.
Yes, quick charge is programmed to only charge up to 60% 18w 9v 2a, then it will charge at a lower than other phones speed at 7w 5v 1.35a, specs are printed on battery heatsink. Charging is 2x slower after 60%. It could be for safety as quick charge will heat the phone fast.

I know but it cant be a hardware problem if all of sudden after v2.19 ALOT people start complaining about battery jump issue..im on 551 tho..

To really know if its hardware, reboot in recovery, clear data&cache, then flash the original firmware from asus website. Start with earliest firmware and try to pinpoint with which one does this issue occure or not.

Does anyone know if cyanogen mod fixed this issue?

I had this problem too, battery jumps from 70% to 100%, so i did a calibration and now the battery is perfect (I got double autonomy also).
For calibration:
1) Discharge the battery under 10%
2) Switch off the mobile and charge it 2 hours more from a full charge
3) Unplug the cable for 10 seconds, then plugin again and charge the mobile for a few minutes
4) Switch on the mobile with the cable plugin and when the android system is fully loaded, unplug the cable
All of this for 3 times

Question What's the typical charging speed for Poco F3?

So I charge my phone today from 32% to 100% in 1 hour and it seems like from the videos other guys get a 0-100 charge for that time. So I was thinking that either I have slower because I am using a UK-to-EU adapter for my charger (got it from UK) or that this speed is the typical one. What's your speed guys?

I like to charge my phone slowly (less than 10W - 3-5H charge) overnight which helps improve battery life.

1C charge means 1 hour charge from ~0 to 100%.
2C charge means 30 min charge.. Why would you want to do that to your battery (half capacity at 500 recharges)?
Overnight at C/3 to C/5 does great things for the longevity.

The state of the phone also matters. Wifi, bluetooth, mobile data, music, video, apps, brightness, photo, camera, sensor, power save, battery temperature, surrounding climate, ... etc.
Adapters may also have their maximum output capped. Check on it's spec.

The adapter doesn't have any specs unfortunately. I just bought a EU charger from Aliexpress. Hopefully it charges faster.

Root with Magisk and use Advanced Charging Controller (acc) module.
https://forum.xda-developers.com/t/advanced-charging-controller-acc.3668427/
Or use old USB charger with the ampere lower, like 2.0A or lower.
That is achieved with slower charging.
PC USB socket most likely will charge VERY slow, to the point that you want it to charge faster.

You will likely need to buy chargers made by Xiaomi if you want even faster charging.
Some technologies will need to match if you want them work at fullest.

Yeah this charger is supposed to be legit. Will wait and see when I get it.

Just like the Redmi Note 10 Pro and Poco X3 Pro, among other Xiaomi phones, the Poco F3 battery supports 33W Mi Fast charging and the phone ships with a 33W adapter and a 3A-rated cable.

It has the ability to control and lower the current (unit in mAh default). To make the current controled, you apply the set current and then reboot.
You can read the README in github for more info.
You have to test it though, I can't.
Use app Ampere to confirm the charging speed.

As correctly said by pl1992aw, I use an old 1A adapter that goes from 20% to 100% in under 5 hours.
With the same strategy my Tab Note 10.1 (not 2014) still has a working battery although it's of no use anymore..

Hahaha that's really overkill I don't want this kind of treatment.

Also charging speed changes based on battery percentage to make battery last longer

The idea with a low power charger to extend the battery life is really nice, cause i usually charge my phone over night and don't want to stress my battery for nothing.

Yeah nobody should want this. I used to mess in the kernel & alter the charge controlling voltage & current values. Soon I realised and concluded that charging a lithium battery with high voltages(9v fast charging) or high current significantly degrades the life of the battery. In addition, charging the battery upto 80% increases the life of battery by 4x in comparison to charging it upto 100%. Phone brands play a trick on us keeping their planned obsolescence marketing in their hands. Now I happily charge my phone with old 1 amp charger. It does slow but the battery wear data is really satisfying.

To add, fast charge is for convenience and emergency eg. forgot to charge at night and need to rush in the morning.
