slow charging speed - Xiaomi Mi A2 / 6X Questions & Answers

Hi, since a week or so my phone is charging very slow. Anyone faced a issue like this?
With custom rom the speed is really slow, with stock is a little higher, but still slow.

[Think Tank] Modify Kernel to fix charging

I haven't actually looked at the battery driver or even the kernel for that matter, but does it specifically state the cutoff voltages for charging the battery? If it does, we should compare those to what the phone is charging the battery to when the phone is off and make them match. Hell if you want to live on the wild side bump it up another .05 - .075V or so...
Just a question.....but do you know what you are talking about??
Froyo seemed to solve the charging 'problem' for me, then again I never had a charging problem.

Erm, how did it fix it? We still have that problem.
I believe what he is talking about is modifying the kernel to allow the battery to fully charge when powered on rather than leaving the "buffer" which requires the bump charge to get the extra 10% or so out of the battery. I'd definitely like to see this as well, but I've found performing the recalibration did help a bit.
Disclaimer: I'm a noob and don't know ****!
However, it would seem if htc (or google), put code in the kernel to prevent the phone from charging to 100% while turned on, I'm sure they had good reason. My guess would be to keep the phone from over heating.
It would seem that if the phone is on and draining the battery, but at the same time you're trying to charge the battery, achieving that last few percent might be difficult and could take considerable more time, and thus getting hotter.
Just a guess though.

I'll look at the battery driver when I get home (currently at work), but I have seen devices where charging limits were invoked directly in the kernel. These could be modified if they are.
On the issue of heat, manufacturers play it VERY safe. It looks bad if someone is charging their phone in their car during the summer and the battery cooks off in the passenger seat. I'd be fairly comfortable pushing the battery to a little bit higher voltage than it is right now.
What about the charging SPEED? Myself and several others have noticed that Froyo ROMs charge at a much slower rate, plugged in to ac power, compared to 2.1 Rom. For me, it takes about twice as long to charge. Is this something that could also be addressed with a kernel fix? I literally went from being able to charge from ~10% to full in about 90 mins, to now taking about 4 hours on Froyo.

The 2.15 radio probably broke the phone's ability to differentiate between the wall-charger (fast) and normal USB (slow). The reason I say "radio" and not "kernel" is because it charges slowly when powered off as well. Hopefully the radio included in the upcoming OTA will fix this.
I had the slow charging problem on the 2.05 radio as well but doesn't change much about what's being said about a potential fix.
Anyone able to confirm that this (something in the radio) is the reason?
Hope the OTA comes soon so I can get back to recharging in a timely fashion.

Apparently you are one of the users that were lucky enough not to have this issue. This thread is not for you. Move on. And btw, Froyo did not fix this problem. Again, nothing for you to see here, move on.
For the rest of us who are interested in solving this issue we will continue to put ideas out there in the hope that a smart one figures this out. Until then, we will keep reading about how fortunate some people are and how some other unfortunate people are willing to work on this. Thanks OP.
the difference between bump charging and not never really affected me because the phone charged so damn fast, that just plugging it in for a few minutes helped out a ton. but now with froyo, it literally take 5 to 6 times longer to charge to 100%. its ridiculous
i got sick of letting my phone charge overnight then 10 min after i unplug it in the morning its down to 92%. and unless you charge it while the phone is off it rapidly drops all the way down to like 80% before it starts decreasing normally, at least for me. so i started turning it off and topping it off in the mornings for about 30-45 min before i would leave for work, doing this i noticed a HUGE difference in my battery life through out the day. that got to be a pain because sometimes i just don't have time to do that in the mornings, so i ended up buying an external charger and an extra battery. this way charge the extra battery overnight on the external charger, pop the fresh battery in the phone in the morning and i'm ready to go. but all this could be avoided if the phone would charge the battery as good as the $2 wall charger, so if you could find a fix for this battery problem it would be awesome.
I had slow charging with 2.05 and 2.15 radios, unfortunately...
Did any of you that are having this issue root and install froyo immediately after buying the phone? a friend of mine is having a similar issue. Have you tried battery recalibration? Also I would recommend checking your up time and awake times in battery info and see if there's something keeping your phone awake while charging . One last thing, try installing battery save mode toggle from market.

I've been messing with the slow charge issue all night tonight, and as far as I can tell, it is not the 2.xx radio, and it must be the .32 kernel.
Slow charging started for me when I installed the first 2.2 leak which had the 2.05 radio, and remained on the the 2nd 2.2 leak and 2.15 radio. Before that I had the 2.05 radio on 2.1 and charging was normal, tonight I rolled back to complete stock 2.1/1.0 radio and charging was normal again, I kept the 1.0 radio and installed a 2.2 rom, charging slowed again, changed to 2.15 radio, still slow, so I installed the old CM6 test 8 rom which was used the old kernel with the broken camera, and sure enough, charging was fast again.
I'd really love to figure this out, if any of you get on IRC and want to discuss this, /msg digi

Great work. on testing at least...
Is there anyone out there who can help fix this? I hate these slow charge times.
I thought the issue was that the phone starts running off battery one its at 100%, not that it can't charge the last 10%...am I misunderstanding that?
I've tested this by taking it off the charger as soon as the light turns green...seems I get much better battery life this way.
This doesn't quite explain why some of us have had no problems at all either. Maybe an issue with newer devices but personally my device has been up for over 31 hours since charge and haven't noticed this issue but a friend of mine has complained of it, and he recently bought his device. Tomorrow after I charge my device I'll post with findings after charging.

this has to do with 2.2 and new kernels. not stock 2.1.

I pre-ordered my phone and I have the charging issue as well so it can't be new phones vs old phones. I hope it gets figured out soon.

with charger in 100% charger out 97% recently

did not have this problem befor flashin jvs but now when im charging it indicates 100% battery and directly when i unplug it it goes down to 97 did not do this before flashin 2.3.5 and I even flashed 2.3.4 now! I managed to get 98 by disconnecting and connecting charger many times. Why?
I have darky's 10.2 Exrtreme or final - can't remember
I have the same problem. But even worse mine sometimes only charges to 60 or 65%. I can get a full charge after several unplugs and re-plug but it takes a while.
The big problem is once it fully charges it seems like the phone stops charging completely and then begins to drain out - should it not maintain the full charge even if left charging at full?
Any help please.
Thanks

my phone is using build jvq -not sure if that makes a difference. I am new to all of this. Had a friend help me with the flashing. Anyway I didnt think my issue was normal - its a pain because when I charge my phone overnight - I cant simply unplug and take it away with a full charge.
Any ideas how to rectify this?

Well dude 97% is normal i m just asking to guys who hav 65%.

I did some more reading. Apparently my problem is a bug with respect to SGS and gingerbread. Once the phone reaches full charge - it stops charging and even though its still plugged in. At this point the phone drains (presumably like normal depending on what you have running in background).
At this point the only fix is to flash back to froyo or I think charging the phone while powered off would work too. Not much of a fix but at least when I wake up in the morning its fully charged.
For others with the same problem as me see this thread:

If anyone else has a better alternative I am all ears.

Le 2 slow charge issue

Hello everyone.
My Le 2 has been acting weird for the past two months. It takes more than overnight for a full charge. I've checked with the charger, wire. It's all fine.
The issue must be with the phone itself.
Please let me know if there's any fix.
TIA
You can use any custom ROM bcoz they have fast charging enabled while screen on also which is not possible on eui

I have faced the same issue with RR 20170220 build...the same issue faced even on lineage 13....so returned to eui now i can feel the speed...But should mention that L14's is much better compared to eui's fast charge..
I'm facing the same issues. My le2 is also charging very slowly please tell me if there is a fix.

Phone charging Extremely slowly... How to diagnose ? Experts Respond plz

here's what happend
I have flashed Unofficial RR rom . It was charging regularly.
Then i flashed renice kernel.
Sometimes Phone was charging relatively slowly but then it fixes by itself .
Until recently it was occurring more and more.
NOW it charges verrrrry slowly 7 8 hours and not reaching 100%, still at 60%!!
So i decided to flash Ultimate kernel to see if anything happends..
no luck
I think somehow the kernal changed the charging voltage. or It may be that battery needs to be replaced..
How do i diagnose what the problem is ??
p.s. I have tried calibrating battery multiple times both by app and manually. Also tried multiple chargers and charging cable. Even tried to charge via pc.
Mr RR 5.8.3 is having very slow charging what can I do plz give me an answer....

If the rom was not charging above 60% you should just restart the phone with a charger on and it will just jump to a 100 it's not calibrated well calibration apps don't work
Same problem.....after the first charge after fresh flash....takes me around 10-12 hours to full charge even with a proper dock and cable.....if I use the device while charging then the charge gradually decreases...

I know that's the problem of the ROM I also experienced the same problem on that ROM change it to dot os with venom kernel 3 hour of screen on time while playing pubg mobile and if you want you can push it to 4to 5hour (venom kernel has built in fast charging 2 to 3 hour max from 0) if you didn't enable fast charging 4 hour max good luck

Charging issue after porting back to stock

Hello folks,
I am facing a weird issue while charging my Moto. I have been using Pixel experience ROM for a few months now and I decided to port back to stock after Oreo release announcement.
I am facing a charging issue with the stock ROM. Fast-charging has stopped working altogether.
-The phone charges very fast if its switched off but when you switch it ON the battery will discharge at the same speed it was charged.
- If I charge the phone while it is ON it takes about 8 hours to charge but the battery drain is normal in this case and the phone easily lasts 12-14 hours with minimal usage.
I flashed the Pixel ROM again and now charging works fine.
Software channel : RETIN
Stock version I used : 61-2 (Indian Version)
I am confused as the issue is not with the phone but with the stock ROM. I have a clean copy of the stock ROM as well which I had used earlier and had worked fine.
Motorola blog says the issue is from the March update. Anyone here who is on stock ROM with a locked bootloader facing the issue??
Any suggestions/help would be appreciated and upvoted.
Thanks in advance.

Turbo charging works same way in all ROMs, and it should work in stock ROM (as it works in custom ROM).
Turbo charging stops at 42℃ temperature, make sure your device is less heated than 42℃ and use "Ampere" app to monitor charging rate and temperature.
