I noticed my GN charges until 100% or "fully charged" (battery widget that spells it out). Shouldn't it be 97% or 98% max when charging to prevent damaging and preserve longevity of the battery? Or is this some new thing with 4.04 that it'll tell you 100% when it's really 97%? I do notice it drops down to 99% really quickly.
I'm stock on 4.04 and I'm using the provided USB cable and charger plug.
Thanks.
I take it you came from a Nexus S before? I was surprised too but I believe it cuts off the charging to prevent overdose of electricity. No worries on it mate.
It will charge to 100% of what ever value you set or as default comes.. Like you can see on the screenshot

Not everyone uses that.
The way the battery works is it charges to full, then takes itself off the charger until it goes down to say 95% and then at that point it goes back on the charger until it's at 100% again, so on and so forth.
Using custom ROM?
Maybe you need to calibrate the battery after you flash new ROM

Wiping batstats does nothing.
so basically it is safe to just leave it plugged in all the time then, the phone by default is DEFINITELY stopping charge at 100%, Correct?
because i know 2 facts about lithium batteries which i learnt today....never leave it permanently charging. and never let it drain fully all the time (the 40-80% charge rule).
im just worried that if i leave it plugged in it'll continue charging even when its at 100...
Do you know if - with that different kernel/ROM - whether you can set it so that you can leave it plugged in - and it won't charge past say....96%. And when it reaches that limit, it lets the battery drain back to say 40%. Before charging again - any software that will let you do this?

Is how phone even on the charger that long..? Something like over night won't kill your battery. The software is supposed to tell the battery when to take itself off of the charger and when to go back. You can use a kernel that will let your battery ONLY charge to a certain percentage.

You do know todays chargers have technology in them to prevent this right? They have for a while, overcharging is mostly a thing of the past, unless you buy cheap, flea market chargers.
in Recovery Mode there is an option called "battery ststus calibration" (something like this which I cant remember) . actually any percentage of battery use can be "calibrated" into 100%, the number is not important.
Okay, as long as charging up to 100% isn't damaging my batteries.
I did come from a Nexus S, and I always thought that when it stopped charging at 97% that was a good thing to prevent damage to the battery. So naturally, when I see it's going to 100% every night, I imagine it's damaging my battery.
Thanks all.

You cannot calibrate your battery. You can condition batteries. Wiping battery stats and so called calibrations apps do absolutely nothing.

That's just because that's how the nexus s battery driver was written. The galaxy nexus driver isn't written with the 95% recharge limit. Its OK though there's no danger whatsoever leaving the phone charging overnight.
i mean, the feature is included in some of the GN roms
Sent from my Galaxy Nexus
Yeah I know some devs added it in, but its nor in the stock rom from Google.
I've had my Nexus 5x for a couple months now, I bought it through amazon refurbished. (My girlfriend has the same device, she bought hers brand new. Her's is the international model though) Here's a listing of the charging cables, and chargers that I have:
Anker Quick Charge 3.0 and USB Type-C 24W USB Wall Charger http://amzn.to/2mitz3n
Anker A to C 6ft cable http://amzn.to/2lbw2HW
Anker 24W Dual Port Charger http://amzn.to/2mx16Tt
(I bought the a to c cable to be able to connect to pcs or whatever, and the charger i had for my Nexus 5 and other micro usb devices.
Standard Google Charger https://store.google.com/product/usb_type_c_18w_power_adapter
Obviously the middle item there doesn't charge at full speed, it isn't intended to. But my charge rate using any of those devices is still over all over the place within each of those items specifications. So it isn't likely that is a cable or charger issue which is normally the issue when someone has charging rate problems. yes i know the charging rate slows down as it reaches higher percentages to prevent over charging and other types of battery damage.
My phone can be down to 20% battery when I plug it in and it could start charging at 110mA or 2000mA+. Whatever rate it is though, it isn't going to stay that way for very long. If it starts low, then it might work its way up into the 700-900s slowly or to around 1000mA. If it starts up high 2000mA it'll likely start working its way down slowly into the 1000-1800mA range.
Sure charging at slower rates helps the battery to last longer, but when i have no control over this, and at times it discharges faster than it is even charging it is bad. I can actually deplete battery sometimes, if its charging while video chatting. Albeit very very very slowly, but still. The battery life and range seems to be very good aside from this charging issue. The connection port on the phone seems really quite solid as well and wiggling the cord doesn't seem to affect the charge rate as best as I can tell.
My girlfriends 5x charges in about half the time that mine does, or sometimes its even worse, i just have to pay attention to what it is doing when i plug it in. So my question is, is this a battery problem or is there something else going on with the phone? What is it that throttles the charge rate down as the battery % gets higher? Is there a chance this could be faulty and causing it to be all over the place like this? Any ideas about this would be very helpful thanks in advance.
Ps: I really do love the device, it works great, I have no issues with it beyond the charging rates that can be all over the place. I can go from 10% battery to 75% sometimes in half an hour or so. Then i get times where it takes well over an hour for that much.
(I use ampere to measure the charge rates)
Charge rate goes down with higher battery temperatures. Let the device cool down a bit before plugging in, also keep the screen off to allow it to charge at full speed.
The charge will also slows down as it fills up, the last 10% will take the longest.

I appreciate you taking the time to respond, since you are the only one thus far. But as I said I'm aware of the charging slowing down for those reasons, and I've got another device to compare to. It isn't the same, and the device isn't hot.
There is no problem with your battery. The phone is badly designed. Unfinished SoC combined with a small battery and a big screen. Your money is better spent on something else.

Personally, no issues with charging here. Always goes 15% to ~90% in 60 minutes with the stock charger.

I don't have any issues with my battery discharge rate. For what it is, and what I use if for I'm happy with it. And from what I've read about the usages from others I think I have no issues there compared to others. I'm just referring to the charging rates, the way it charges

OK, a serious question:
1. Charging speed is affected by Charger (the thing that plugs into the wall), the Cable (how long or thick it is), and the Battery (how hot, how full it is). This is the basic, moving on.
2. Sometimes the C port is buggy and doesn't correctly detect the maximum amount that a cable+charger combo supports. Download Ampere or some other current measuring tool like GSam (although I never bother with GSam, Ampere is awesome), and make sure the max amperage is 3000 mAh. Anything lower than that means you have a low-powered charger, a less-than-optimal cable, or a hot or near-full battery. I recommend plugging it in at around 50% to make sure the near-full charge speed drop doesn't affect anything during your tests.
3. If that doesn't work, replace the battery. Final line advice.

He's already using Ampere to measure and has 3 chargers to compare with.

Hi,
Is it possible to turn off the dash charge? 5T is charged only overnight cause it can last the whole day anyway.
PS: I can turn off Fash Charge in my Samsung Note. So it saves battery if I charge only overnight and don't need fast charge feature.
There is no stock option for this. Maybe a custom kernel can support it or a custom kernel that doesn't support it at all would also be a possibility in theory.
I would suggest using a normal power adapter instead of the Dash charging one. Even a normal USB C cable prevents Dash charging as it can only be used with OnePlus' own cable. So maybe get a cheap USB C cable and use that?
Use a low amperage charger. Something like 1000mah. This will slowly charge your phone overnight. But make sure you use a quality charger.
Why would you want to do this? The OnePlus dash charger works differently from other chargers in that it holds the heat in the charging block. If you use a standard adapter you would transfer the heat to the phone while charging. I would NOT recommend doing this.
Sent from my ONEPLUS A5010 using Tapatalk
I use an Anker IQ 6-port Charger with a couple of fairly good quality cables.
I personally try to avoid any kind of fast charge because it will end up damaging the battery life faster than "standard" charge, even if the heat is absorbed by the DASH charger block. IQ Charge adapts itself with the needs of the device connected.
And my unit stays cool if I touch it while its charging.
Charge however you want. But for me, dash charger while getting ready in the morning or when you have a free half hour. Forget about charging overnight. I don't know your usage but for me, this works. The phone just sits on my nightstand without connecting overnight and I lose a very minimal battery amount.

It's fine at even less than 1 amp. We have two 5Ts in the house and charge them at night at 0.35 - 0.45 amp.
I saw the dash reduce Ampare when pass above 80%.
(When not rush I use official iPhone 1Amp charger.)
Use 5V/2A standard charger to standard usb type c.
Oneplus 5t = 5V/4A
Quick Charge = 9V/2A
Dash n QC have more power!
I'm using an old 1A Samsung power adapter and dash charge cable and in addition I also use Battery Charge Limit app to limit charging the battery to 80%.

No, it does not, especially not with dash charge. The excess heat is stored in the charger and is not transferred to the phone, and the heat is the only thing that degrades the battery faster.

Your informations are not correct.
Dash (or VOOC, which is the very same technology since OnePlus is an Oppo brand) uses high current fast charging instead of high voltage charging (QuickCharge 2.0/3.0 uses high voltage) and the circuit that produces heat in phones that are not Dash/VOOC compliant is inside the phone, while in Dash/VOOC is inside the charger.
Oppo and OnePlush themselves have acknowledged that it makes SAFE to use the phone while it is quickcharging, NOT that the battery is not getting damaged by the use of a fast charging method, even if it charges at a lower voltage and higher current.
The use of any fast charge technology implies to shorten out the overall battery life.

Just because they moved a bunch of the power regulation stuff to the charger doesn't mean the battery doesn't still get warmer. If you push 4 amps of current into it, it will heat up more so than when it receives, 1 amp.
Now you have me curious though, I guess I'll have to pay close attention to the battery temp next time I charge my battery. I've never used the dash charger, but perhaps I'll have to get it out of the box, and test with it as well just to see what kind of temps I see with a more powerful charger as well. I'm curious to see how much temperature difference there is.
I know on my Nexus 5X my phone always lasted long on a single charge when slow charged (0.35 amps), vs using the factory 3 amp charger.
Constantly topping up the battery overnight for 5-6 hours (assuming your slow charger will charge it to 100% in 2-3 hours) is worse than using Dash to charge it quickly in bursts in the morning and night when you have a spare 30 minutes.
I would never leave a phone stuck on a charger overnight. Especially since even the slowest charger in the works will charge the phone to 100% in three hours or so.

How does it imply that? Heat is the only factor. Phone is not getting hot(ter than slowly charging) when charging.
What is the truth? With the rapid charging the battery deteriorates faster or better a slower charging?
Anyone knows if is any way to disable fast charge?
Dont like fast charge since is worst for battery life.
For Battery Life is fine. This model dont have any fast charge or something similar. The charger included its fine and cant damage the battery.
Do not mix stanrdard fast charging (=being able to suck more than 1A from the charger) and QuickCharge (Qualcomm charging technology, involving e.g temporarily increase of charging voltage well above 5V and charging current well above 2A). A2 Lite is able to fast charge, just use Ampere or similar software and you see how much current it takes.
To the OP: I read that some custom kernels have this possibility, but no idea if any of few customs roms for our device has this capability. By using external software you can limit battery charge to e.g 80%, which would help a bit, or simply use one of old chargers, which could push around 500-700 mA max.
I'm using this magisk module: https://forum.xda-developers.com/apps/magisk/module-magic-charging-switch-cs-v2017-9-t3668427
Basically it helps to extend battery life by limiting the maximum charge, charging the phone slowly on certain range of battery level or when the battery reaches certain temperature.

I wondered about this too. If you're not in a hurry (say, charging overnight) then maybe the slower charge will ensure optimum battery life.
I find that using a long (2M), cheap charging cable prevents fast charge!
That's understandable because the electrical resistance will be higher than a short/quality cable, so limits the charging current.

And battery was already almost 2years old. And with using quickcharger it got really bad battery in few months.

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

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
