80% charge threshold broke on rooted US snapdragons - Samsung Galaxy Note 8 Guides, News, & Discussion

Works on s8. Figure it should work for any US snapdragon faced with 80% charge limmit from rooting.

Charging the Battery takes forever!!

It takes all night just to charge this thing, when iplugged it in the wall with the USB cable it came with it takes like 2 hours and it only went up like 15-20% and my Acer iconia charges fully in an 1hr and a half, any way to make it charge faster?
Pretty much all night. Mine takes about 6 hours to reach 80%, then it gets stuck there from 1-3 hours, then it goes to 100% in another 1-2 hours. It is a big battery, but not any bigger than laptop batteries!

Samsung is known for being a bit on the conservative side with battery charging. Original GalaxyS phones had a current limit of 600 mA. GSII phones have a limit of 650.
In addition, all CPU/screen power usage counts against this limit - so if you've got 200 mA of screen/CPU power usage, that's only 400 into a 2500 mAh battery on the 5.0.
It looks like they planned for a limit of 700 mA on the 5.0, but at some point dropped it to 600 for some reason. (There's comments in the kernel code indicating that it changed...)
Good news is that it can be changed in the kernel to charge at up to 800 mA. I'll be working on this on the US 5.0 in a week or two.

Battery Charge Limit - Preserve your battery.

Hey, just wanted to let you guys(and gals) know that this app works perfectly on our axons: Battery Charge Limit.
https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002
It does exactly as the name suggests, stops the battery from charging beyond a certain percentage, thus for example if you set a limit of 80%, your battery will preserve its health for around 1500 cycles instead of 500 cycles of charging to 100% before degrading by ~20% of its total capacity.
Enjoy the app guys, tested on B19, stock kernel, rooted.
So the way to have 1500 cycles is to only use 70% of battery at best. Because going under 10% is not exactly good for the battery either. I don't want to have an even worse battery life, so I think I'll pass, thanks though!

Don't go under 90ish as you will stop charging whilst quick charging and will damage the battery even more than if you didn't use the mod so just be carefull

Dont let them fool you, you dont need this app. The charging controller of your phone actually already has its safety margin built in. Same on the low end. This means you can not charge your phone to its physical maximum anyway, it will show 100% whipe the physical charge in fact is ~95% and will shutdown showing 0% while physically there is still about 10% of power left. So your battery is safe from this kind of damage anyway.
If you want to extend your batterys lifetime for real, try to charge it as often as you can, keep the charge as high as possible. Flat charging is the magic word. This is what your charging controller does when your phone is connected to ps for longer when it shows 100%, it in fact lets it deplate 2% without showing and then charges it back, thats called trickle charging and is the best treatment practice for our bateries.

Samdung pretty much confirmed they do this (or better) in the S8 and later (and possibly the S7). But has any other company confirmed they have battery longevity tactics built in?
Personally I use AccuBattery since I've had it for a long time as a charge alarm/monitoring tool. I use a 1 amp charger instead of the 3 amp charger that comes with it and charge my phone at low amps and voltage which prevents the battery from heating up. So low charge, low heat. I don't want a degraded battery in a year because I don't know when I'm replacing this thing.

AccuBattery is no good for giving an accurate estimate of the actual capacity when you're charging at low %s. For first 50% it'll calculate something like 3500mAH+, for the last 50% it'll estimate 2000 or lower. If I had to give you a rough estimate of what I actually think it's at, it's roughly 2900-3000mAH. When I first got it, I estimate it was around 3100-3200 a year ago. I HATE that phones no longer have replaceable batteries. That's half the reason I wanted an LG V20, I could just murder the battery and just pop in a new one every year. Sadly the V30 is sealed, following the BS trend of planned obsolescence. Thanks Apple.
Oh and I almost forgot, I typically charge my phone from 20% to 50% after it drops 30%. Then sometimes once more if I use it some more. On average I charge about 50% worth a day without going over 50%. Even with such light battery usage, keeping the battery 30C or lower 99% of time, and keeping the voltage below 4.1 again 99%, it's still degraded at least roughly 200mAH in a year. Rarely when I know I'll need longer battery life I charge it to 80%. It's a cheap quality battery. ZTE cut corners. This was my first, and unless I have no other reasonable options, it'll likely be my last ZTE phone.

can you TL;DR this for me?
-So i better keep charge between 20% and 80% yes?
my old sony phone form 2011 still works nicely, as it had Quality battery (over 2000 cycles already) yeah does not last long 2/3 but still. useable.
And i agree, replaceable batteries is must have function, My old S3 and S4 worked for "ever" because of that, every year new battery and another year of usage! (s3 still going strong since 2012 !!! )

Apple has been using enclosed batteries for like 10 years or so.
You can do better than the app by setting a lower maximum voltage on the Axon 7 instead. I posted about the discovery awhile back on that thread https://forum.xda-developers.com/showpost.php?p=74746734&postcount=1353

Essentially, yes, that's what I keep hearing whenever I dig for information. If any of the stats of AccuBattery are accurate at all then it also supports that going over 80% causes multiple times the degradation that charging up to just 80% would. These days I try not to go over 70% based on app estimates of degradation. These days I need more than the 50% I was previously charging to.

Quick Charge 3.0 Kernel?

Hi, I'm using the 4x snapdragon, with the final Resurrection rom.
Can someone recommend a good kernel with quick charge and works alongside this rom?
Thanks in advance.

No they did not, it's not kernel related but the charging board and battery that are not compatible.
Thanks for the info.
Why so obsessed to quick charge?
It's not much faster than the regular charge.
Quick charge enabled phone charge the 3000mah battery in 1.5hours... If the battery is larger 4000mah, it will takes approximately 2 hours to charge.
RN4 regular charge is about 2 hours 15mins... Its just 15 minutes longer and if we usually charge it overnight, its nothing difference... you want to take the unknown risk?

Yes!
We do all sort of things with our devices that are outside of "safe use". We overclock and overvolt them, flash stuff that could potentially brick them, etc.
As to why? I wouldn't charge the device from 0-100 with QC enabled but i sure as hell would like to charge it for 5 min and get 20-30%
If QC could be enabled it has to be tested sure, maybe it wouldn't be a good idea with an ambient T of 30C maybe the cut of point would be 60% or 20min. But yes I would like to test it.

When it comes to play the electricity, the risk isn't your phone brick but bomb...
And it will nowhere near 20-30% in 5 minutes.
LG G5 that have QC 3.0 enabled charge around 10% in 5 minutes. its with 2800mah battery, faster usb-c, etc...
What's the battery charging rate with a stock charger? My stock charger gives 1300mah at 70% and a Blitzwolf QC 3.0 gives 1700mah at 70%.

Well sure it won't be for every one, there is a real risk of the battery catching fire (bomb is a bit hyperbolic) . That's why IF it's possible people willing to take the risk have to test it out. Some might think it's worth the risk though.
My admittedly rusty back of the napkin math says it should be theoreticly possible to get 20% With 20V and 3.6A in less than 7 min.

you are wrong,
RN4 snapdragon need 3 hour 5m for fully charged (10~100%) with 5V2A charger
and the advantage of QC is they charge very fast in 0~70% (about 30min only) then slower until 100% (max 1H 40m total)

Well my sister has a zen 2 too... It's not quick charge..
Quick charge is qualcomm tech, zen 2 have intel on it.
And zen2 just have 3000mah battery on it, mido is 4000mah capacity... It's 25% larger. Its totally different...
Before using mido, I was using mi5s that have QC 3.0, with legit 3.0 charger and usb-c, its no way 60-70% in 30 minutes.
Well I have 2 mido, come with 2 different stock charger. One is RN4 global, with EU plug... Yes it will need about 3 hours to charge. One is RN4x, come with chinese charger. It need 2.5 hours to top... 2 hours will get you from 10 to anywhere between 10-90+%, the last 10% is very slow...
Will provide logs later, because I've fully charged my phone this morning and still have 78% left this afternoon.
I've measured this morning charge... Start from 17% to 90% takes 100 minutes.
Note 4 takes less than 2 hours for full charge 10-100%. Just don't use the phone while charging.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Samsung Galaxy Note 9 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
will/do the Exynos variant support faster charging than s8, something similar to quick charge 4.0 or even 3.0? as on s8 adaptive fast charge is same as quick charge 2.0 so hope it will improve

I am sure they had mentioned it if they changed it...
Can anyone who has a Galaxy Note 9 measure it using an USB wattmeter or multimeter?
Does anyone know if the wireless charger that has just been released with the note 9 (the single pad not the duo) charges faster than the convertible wireless charger released with the s8?
I looked up the specs of the Samsung fast wirless charger pads that came out with the S8, S9 and the Note 9 on the FCC, and all 3 have the same power spec, so they probably all charge at the same speed.
The Duo that has just been released can draw more power, probably due to needing to charge 2 devices.

Is the latest Quickcharge technology compatible with Samsung's 95% after 1 year battery promise? (Applicable to Note 8, waiting on confirmation for Note 9)
I'd lay odds on the feature being omitted for battery reasons at this stage.

So the Note 8 has faster charging than the 9? My response was getting at that QC has not got faster on the 9 due to Samsung maintaining the 95% promise, it might not be possible under a faster QC....

How do you check battery life?
Not satisfied with battery life and fast charging is a big joke besides my old p20 pro ???
People, don't forget, you're charging a much larger battery. It's not really comparing apples to apples unless the batteries are all 4000mAH. So, if you quick charge your 4000mAH battery, and adds 20% of battery power in 15 minutes, it added 800mAH, while charging a 3000mAH battery for the same amount of time will also add 800mAH of battery life, but will show that it charged 26% of the battery. IT'S THE SAME THING, and it didn't charge it any faster!!! A larger battery is going to take more time to charge than the previous Note 8 battery!

Question How critical is it to just charge to 80%

I keep reading that you should try and just charge your phone to 80% to help keep the battery healthy, as going to 100% can shotren the life span of the battery.
How ciritcal is this?
I know letting your phone run down to 0% is bad as it takes a fully clylce then to get back too 100% and this is not good for the battery long ter, but i must confess i usually let my battery get to around 50/60% ish then charge back up to 100%
I've always charged my phones fully and never noticed any issues. Maybe if you plan on keeping a device for 10 years, but for the usual lifetime of a phone it's just fine. My OP7 is 2 and a half years old now and still has 86% battery health. I've seen others in Telegram groups say that they never charge to 100% and when they post their battery health it's not much different from mine, sometimes even less.
I think modern batteries are fine being fully charged ... otherwise the OEMs or battery manufacturers would limit them to 80 or 90% by default.

I've seen others in Telegram groups say that they never charge to 100% and when they post their battery health it's not much different from mine, sometimes even less.
I think modern batteries are fine being fully charged ... otherwise the OEMs or battery manufacturers would limit them to 80 or 90% by default.

Hehe yea, I guess they all show 102% then because I have that as well
I like the adaptive charging, set up your bedtime and alarm for getting up (or turning over) After bedtime, phone gets trickle charged to achieve 100% at morning alarm. No excess heat etc. Phone then lasts me all day till bedtime when put on airplane mode, switch off Wi-Fi, & sleep. Works for me.
I'm showing 106%
I always charge to full, using adapting charging over night. Charging slowly and keeping temperature down is more important than keeping it to 80% from my understanding.
I just lay my phone on a slow charge Qi pad every night and when I get up it is at 100%. Nexus 6, Pixel 3, now Pixel 6. Perhaps my battery life went down a bit on my Pixel 3 after 3 years, but not enough to notice. I think 100% charge (at least slow charging) is safe for 3 to 5 years of battery life.
Li's like frequent midrange power cycling; it can extend the lifespan hundreds even thousands more full charge cycles.
Voltage and temperature are the Li's biggest stress factors. Low or high temperature charging can cause Li plating.
The higher the cell voltage, the faster it degrades.
The same is true with temperature.
Personally I just replace them every year or so as a failed Li can severely damage a phone. They tend to swell during a failure which can easily damage the display.
My Samsung S10+ is 27 months old now. I'm charging it to 80% mainly daily. Had maybe max 20 full charges and only once or twice to zero. I'm at 86% battery health (according to 146 sessions). Was 92% six months after buying brand new.
I think it helps. Also since the battery is OK (4100mah), dont need that extra 20%.
EDIT: 15W Samsung "fast" charging. As fast as that is ...

A Li is considered degraded when it reaches 80% of it's initial capacity. This signals the end of its useful service life.
Degraded Li's are more likely to fail.
Trust me it's better to replace it before it fails...
I think Better Battery Stats made that reco back in the day.
Charge to 80% and plug in at 10%.
Not so sure that really matters anymore though.
Both my 2 XL and Pixel 5 were plugged in before bed, unplugged when I got up, plugged back in when I hit 10-15% or when I went to bed.
If you plan on keeping your device for a long time (like 3-4 years) doing the unplug at 80% and plug in at 10% might make a diff.

10% is too low. It causes a lot of stress on the battery as it drops below 20% to charge from that starting point or lower.
Worse there's little usable energy after 20% because of the lower voltage. The phone uses the same wattage which is determined by V×A=W, so as the voltage drops it needs more milliamperes to make the same wattage. The discharge rate increases as the cell voltage drops.
A better low cut off is 30-40% or even higher and a high cutoff of 80% although 62% is optimum.
The Li likes frequent midrange power cycling. Charging beyond those parameters is for your convenience at the cost of battery lifespan.
Batteries are cheap and most are easy to replace... so I don't sweat it.
I expect a service life of 1-2 years on a heavily used N10+ battery.
However charging in the 40-72% range yields the most rapid fast charge in the shortest time so it makes sense to use this whenever convenient.
Well, I know things have been updated within Googles code itself.
"Adaptive Charging" / "Adatptive Connectivity" additions.
This was a real big problem for me with my HTC 10, (2016)
Battery degradation threads starting popping up.
I installed Accubattery after 1.5/2 years of owning the device and the battery was degraded to about 77% capacity at that time, IIRC. I was charging to 100% at that time, also.
So, I began charging stricly to 80%.
Compared to my HTC One M8 that to this day still has 90% capacity, and I used that device from the day Verizon released (3/2014) it until the day Verizon released the HTC 10 (5/2016).
I somehow managed to use the HTC 10 up until I bought the Pixel 5 on release day (10/2020).
I was charging the HTC 10 like 3 times a day just get through, and even went back to the HTC One M8 at one point because I had enough, but was waiting for the P5 to drop.
So to answer the question, I do believe it helps.
I do think that Adaptive charging/connectivity help, as well.
I take the view that if I don't need all the capacity on a particular day I charge no higher than 70%, which lands me around 30% end of day. Otherwise I'll guestimate what I need. Off to take some photo's tonight, so will probably charge it to 90% or so.
If you like fiddling around you can use something like Tasker to switch a smart plug that your charger's plugged into on and off at what you consider appropriate battery levels. Makes it all painless once set up. Or you can buy some extra hardware too. I use this in my car to limit the phone's max charge and temperature as, for me, I think most and fastest damage is done in a hot car float charging the phone at 100%.... https://chargie.org/ Not cheap but ok in my mind to hopefully extend the service life of the phone's battery. Less than the cost and hassle of replacing a battery anyway! (I'm not associated with Chargie other than as a customer)
OK, admittedly off-topic, but, this kind of sounds like a variation of the guidance I use for charging my electric car. Don't charge it unless it drops below 80% (so don't keep topping it up), but don't let it go below 20% regularly either. I mostly plug it in at around 60% and let it fully charge. Given the cost of a replacement battery would be more than the total value of the car, I hope this gives me 10 year of life.

EV metering is set up differently. What shows as 100% is likely a conservative 80% charge. Research for that variant.
A 35-40% low cut off is probably better as going lower generates more heat causing needless stress... unless you need that capacity.
Just downloaded the accubattery app and then fully charged but it’s estimating 6,401mah. Must be wrong and needs to calibrate over a few days.
I’ve never had any problems charging to 100% before so I’m not stopping now. I’ll be deleting this app if it keeps warning me like it has done.

Turn it off then.

Hello, I'm using a pixel 6 with two cards sim. When I go to sleep the phone is fully charged and internet/wifi is turned off. When i wake up i have 88% battery (I lose 1,5% per hour). In battery use i see Ims Service. I did a test and in...

I used to cycle from full to empty on my Pixel 2 before recharging, at about 3 years the battery couldnt last until lunch anymore. This meant more cycling, and I could fully discharge/recharge it 3 or 4 times a day. Within 6 months the battery only lasted 5 minutes, it was stuffed. Phone always hot and needed to stay on a charger 24/7, would turn off if I opened the camera without usb power connected.
Held out about 6 months on a permanent usb battery bank, was such a slog to wait until the Pixel 6 was released.
