Edit:
From what I have gathered from those that have provided info.
Around 120*F is normal for heavy use, around 105-110* for medium use, 100-105* for light use. This is with cell data enabled, wifi lowers temps 5-10*, also temps are for extended use scenarios. (over 10-15 min)
Heavy use= 3D game or graphically intensive 2D game, streaming videos especially HD
Medium use= basic games web surfing sites with lots of images or some flash content
Light use= sending SMS, basic fooling with settings or other basic functions, streaming music with the screen off
I think we need to get a bit more scientific about testing this overheating issue out. I need help from a large group of people. I need those who think they have overheat issues and those who do not for the info to be useful.
First off... I believe these temps are just the battery, not the CPU. I think the CPU is running relatively cool as the rest of the phone does not heat up, or it seems what heat is felt is coming from the battery only.
This would explain why people claim that the extended battery does not have this issue. As batteries with higher mAh ratings are able to handle the higher power demands with less heat.
We need to do comparison tests using the same apps across tests and the same use times as well. Also no over or under-clocking and using the same CPU governor. (and between everyone participating where possible)
I have Minecraft and Sleepy Jack, they both produce similar temps after 15 minutes of play time. (around 117-120*F) I do not know if it gets any hotter with longer use because I rarely play longer than that at a time. I am at about the same temp after only 10 minutes so maybe that is the highest it gets.
I know for certain that enabling WiFi has a big impact on the temps. My fiance's phone would only get about 95*F, (according to the SetCPU widget) but when LTE is enabled it would get to 115*F. Mine hits 105* on WiFi.
I want to do at least two tests.
Lets use the following steps to test:
-For all testing the test time will be 15 minutes of play time.
-Lets all use Minecraft since there is a free version and I know the app causes the phone to work hard.
-No over or under-clocking
-On Demand governor
Test 1) Airplane mode enabled
Test 2) 3G enabled (not everyone lives in a LTE area, if you do, data from LTE enabled would be useful as well)
Now some optional tests. I did some rudimentary testing and there seemed to be an impact on temps.
Optional 3) Using interactive governor or Lag free governor
Optional 4) Use a different kernel... If you are on stock switch to ziggy's and vice versa. (this may be the most promising test as since switching to ziggy's I have had a few lockups where the old Android logo pops up on the screen and I need to do a battery pull to fix it. This happens to the fiance's device as well)
If you do these tests, please post the results, and what ROM and kernel you are using. I will keep track of the results and update as appropriate.
Lets see if we can find some consistent data and narrow this heat issue down.
Edit:
Running Ziggy's kernel I hit 108*F kept playing and shortly after the phone did the odd crash I mentioned.
Nice, had the same idea to do one of these over the weekend - you just beat me to it
I've done alot of research/ testing heat wise, and the pseudo-scientific conclusion that i've come to is that in a room temperature environment something like 75-85F idle & 110-115F netflix is normal for this gen of phones (Rezound, Galaxy Nexus, Galaxy S II, etc) - Give or take another 5F if you're using 4G. Seems like some devices are luckier than others & stay slightly cooler, but i'd gauge that they aren't the typical use case. IMO, (along side battery) data is a huge reason we've seen some of the face melting temperatures people have been reporting.
One thing I think would really help this thread is to set an easy to follow format for posting results. For example, here's a few tests I've done:
### Phone Info ###
ROM - Stock
Kernal - Stock
CPU Speed - Default (1.5)
Battery Type - Standard
Case - Generic TPU
## Test 1 ##
Charging - No
Data - 4G (4 bars)
App - Field Runners

Start battery temp - 85 F
End battery temp - 112 F
Total Battery Drain - 20%
## Test 2 ##
Charging - No

This extended battery will get just as hot as the stock, just takes a little longer.
Edit-not quite as hot as the stock, but pretty toasty.
if it's the battery, then isn't the only parameter we need to test is current draw from the battery? no matter what radios/apps are enabled/disabled. It's bottom line is, the more we're drawing off the battery the hotter it's getting? I'd have to bring a pro in here on how Li-ion works in this form factor and why it gets hot, or what corners the battery manufacturer cut to make it possible!
The only time my battery gets hot is when I am in a weak signal area and the phone is searching for the 3G-4G signal. During daily use in a good signal area it never heats up.
My phone (and wife's also) heats up most notably during charging, especially when the battery is around 99% and going 100%. Usually the temp goes to ~ 45C (115F). In some rare cases, it was too hot to touch (dunno the exact temp). But some other times it would stay cool at all time.
Wife's first phone went into bootloop and her current phone is a new replacement. I kind of believe the overheating was the main cause of the bootloop problem.

It's more than just the battery. Also: feel free to post a test - the more data we get from everyone, the better.
One important variable missing: ambient temp.
I was just playing words with friends for ten minutes:
Ambient temp: 67, Screen brightness: 50%,
4g: ON
wifi: OFF
my temp went to 105F, it's NEVER gone to 105F when playing before... and I play it every evening. It was hooked to the USB charger at the time, and when I felt it getting so hot, I looked at battery monitor and my net charge was negative, so it was using more than it was charging off the usb...
maybe something in some of those apps triggers something that causes the temp to rise? a loop? something?

Good layout... and I think you are right about 115-120 degrees is normal for heavy use with apps that really stress the CPU or radio.

A pro huh... good thing I'm here.
Ok I'm not a "pro" as it were, but i know a thing or too.
Its not going to be simply the battery, but I think it is a big culprit, and most of these devices only provide battery temps, not CPU or internal temps, this limits our overall knowledge of what is going on internally. The battery getting hot causes the device to heat up as well so a bad battery that overheats can cause the device to overheat.
All batteries will convert some energy draw into heat. This is caused by the internal resistance of the battery. Li Ion batteries have fairly low internal resistance compared to other types, but battery design an affect power output handling. Pulling more power than the battery can handle or near its limit and you get more heat than normal. The heat to output ratio stops being proportional and becomes exponential. So that means the real kicker is the actual amp draw on the battery. How much power the battery can handle is related to both the capacity of the battery and the manufacturing process/ design of the battery construction. I bet the new devices are straining the battery more than the current design can handle. There are better battery manufacture processes for better power handling, but that increases the cost of the battery.
(BTW battery is a misnomer for these, they are cells, specifically one 3.7/8V Li Ion cell. The difference is that batteries are made up of 2 or more cells. This goes for AAA, AA, C and D cells as well. Car batteries for example are made of six 2V cells, 6V lantern batteries are made of four 1.5V cells and 9V batteries are six 1.5V cells)
This is one reason I want to do a test with airplane mode on. This helps lower the power draw and allows us to get a better overall device temp, this helps us know if there is an issue with the CPU getting excessively hot vs just the battery being stressed to hard.

I assumed most testing would be done at room temps of 68-72 degrees. If anyone tests in temps that are much higher or lower, then that would throw off the measurements.
I switched back to stock kernel, going to check for lockups and issues like I had before.

Charging always causes heat. You are forcing power into a small space.
Charging via USB should only get the battery a little warm to the touch. 95* or so at most.
Charging with AC should get it a few degrees higher. I would think over 100* is odd.
as you reach 100% is when the heat should spike to the max temps I mentioned, before that it should just be warmish.
I will check mine to see how it behaves, but all my R/C batteries behave that way.
Replacing the kernel with stock lowered my temps quite a bit. I was around 110-115 degrees after 30 minutes or so. This was with LTE enabled.
Nobody else have anything?
noticed most of my heating issues when 4g was on (even when idling on 4g). Leaving in wifi and 3g keep the stock battery cool...on the extended I never really notice the heat, even on 4g.
I realize that you're trying to keep things as similar as possible, but I had an issue today listening to the broncos game in the NFL app while charging. It got so hot it boot looped. After getting it back up and running I started monitoring battery temps and even with the screen off and just listening to the game, it would get extremely hot. Btw, I have 4G 4 bars. A couple of times I ran to the freezer and put the phone in it for a couple minutes to cool it down as the temps got above 117°F.
From here, I thought it might be the CPU, so I set the maximum setting to 384 in antutu and then let the phone sit there with the screen off just as before listening to the game and still charging. Same thing, phone got extremely hot, 115°F. Although, what I find strange, is I can watch Netflix while charging and even tho it gets warm, it never gets above 115°F and never goes into the boot loop issue. Same exact location, charger, ambient temps, signal, the works. So I'm wondering if an app is just poorly written and causes some sort of excessive use of the radio.
On another note, I had a rezound battery in my thunderbolt and never had any issues what so ever with heat.

What temperatures are you people expecting to see just out of curiousity? I mean if we run 3d intensive apps, videos, extreme web browsing we're going to see high temps since we are stressing the devices. We do have to remember these are compact devices and they are limited to what type of heatsinks/cooling they can add. From the multiple posts form this thread and others like it, we can see the majority of our devices run at same temps while under load. If it hasn't already been done maybe we should contact HTC and see what they say? Just a thought.

I am trying to find the norms and what is too hot.
I am thinking 115 is normal for heavy use. But we need to be sure, if someone says they only hit 100 under similar conditions as someone that hits 120. it may be that 120 is a problem temp and that 100 is normal. It may also be that the person only hitting 100 is just lucky.

Go play an app that is heavy in 3D, lets see what temps you get. If you go much over 120 it may be an issue.
Running Gun Bros for about 20 minutes gets me up to about 105°F. Right now after the phone had been sitting for 5ish hours doing nothing its at 98°F.

I think it is Ziggy's kernel I have never got 125f when tethering for 30min or playing GTA for 30 min. I am going to try another kernel.
Hi,
I've had the Galaxy player for a few months now, and I'm generally very happy with it. Although I get pretty decent battery life out of it, I'd say normally about five to ten days of idle time with roughly six hours of screen on time and about as much wi-fi on time, with maybe an additional three hours as a music player, one issue relating to battery drain appears to be constant. I'm currently back on stock, but this also happened on Eryigit -- I get very slow drain from about 100-80%, then it seems like the battery goes into freefall, going down from 80% down to 25% in a matter of an hour to an hour and a half of regular use, then slows down again until the battery dies. I tried calibrating the battery several times with no difference. I'm guessing I'm getting pretty good use of the battery overall, but this erratic drainage pattern makes me feel like I'm too often close to running out as the device spends around half the time I'm using it at 25% or less. I've read somewhere that the battery level measurement on the Galaxy Player 5.0 is highly inaccurate, and in fact is only a guess based on the voltage output of the battery. I still have to wonder though, is this a normal pattern for this device?
Thanks, Nir
Hey. I've noticed a similar pattern via battery monitor widget, tho nowhere even close to ws prononced as yrs. I generally monitor the mA rate and it goes from -2ma steadily until 80%, the rate then speeds up. W moderate usage, i get roughly 2 days out of the sgp before charging, when there's roughly 30% or less left.
I also remembr some folks mentioning that the battery wont report greater than 80%; i imagine that 80% acts a sort of border where he readings r concerned.
Try out that program i mentioned to monitor usage. Personally, im on entropys kernel and chips rom (occasionally switching to paranoid android), have undervolted it slightly, and added a few init.d scriptsl aiming for optimal battry life. Also, try out watdhdog lite to monitor any apps that might be wakelocking improperly and Gemini app manager to disable ann0ying apps from starting on boot.

Bah, I think I might have gotten a bum battery. Any idea how much screen on time/wi-fi on time you're getting with a full charge? I use BetterBatteryStats to measure, which also helped me diagnose GPS-related drainage issues (those kernel wakelocks went away when I stopped turning off the GPS, but I'm pretty sure it's a stock kernel issue). I'll try out battery monitor. Thanks!
Well, given that you can have it on idle for 6 days, it might not be thay persay
Actually, onnsecond thought Powertutor is prolly better suited for your issue. It can monitor power use per application
High display brightness; wifi that doesnt sleep even w screen off (it never sleeps by default); apps that enable things like gps, that makes requests and sends info w.o yr consent thru wifi- these, among 0ther things, drain battry life and are other things to consider

And cant say. I usually do 2-3 days before i recharge; i rarely go under 20% and dont game
Also, just caught this- gps is a huge power suck. Like huge. That may be yr problem.

It was same for me on stock rom and every other rom..70% of time from 100 to 10 it is staying on 75% and 25%..and when its on 25% it can last all day with moderate usage dont moving from 25.Its because device only measure voltage which is innacuare ,voltage dont drop linear like mah.

well i had that prob with my old SGP but since i messed it up andgot it replaced it doesnt stop at 80% for like an hour it just charges straight through tht was before i had enthropys512 kernel flashed....now the battery is faster to charge
Well, I suppose another plug for Battery Monitor Widget-
It provides a handy estimate for discharges/recharges that's proved pretty accurate. After entering the actual battery capacity and a few cycles, the app estimates charge and discharge time based upon that as well as the readings it receives. The discharge estimate isn't as accurate as I'd like, but that's probably due to my sporadic usage. The charge time, however, should be accurate since charge times are charge times are charge times.
Jeez- I should like contact the dev for a commission on the app at my rate.
Re-flashing the kernel might help, if A) killing GPS (except when, obviously, you're actually using it) and B) getting rid of those wakelocks (try Watchdog Lite-free) don't work. Eryigit's ROM, from what I remember, already has the Entropy kernel baked in
If you do some search through the past threads, you will find some discussions on this very topic.
Even though the battery performance of the device seems to be quite on par with other Android devices I have used, the amount of battery charge that is being reported is, a general guess at best. As it is, it only shows the charges and discharges only at 5% increments and on top of that, as OP stated, it seems to jump around a lot.... 100%-80% normal drain... jump down to 30% and hold... etc... heck! My device will show full charge and the moment I take off the charger, it drops to 80%... I have 4 5.0 devices and they all do that... I have stock GB, ICS and Custom GB roms and all are showing the same thing. I believe it has to do with the way the charge state is being reported... It must be a hardware glitch and I guess that is why no matter what rom you are on you will see this erratic battery % report.
I have stopped worrying about it since it does not seem to actually affect how the battery is performing.
Oh yes, I saw that post when I was skimming search results, but got fixated on the not charging above 80% part and didn't realize it was the same issue. I guess this is normal then. Thanks!
Regarding GPS: It actually doesn't seem to affect my battery life unless I'm using Google Maps, in which case the GPS flashes in the status bar and yes, the battery drains much faster. Confirmed regarding Eryigit and its custom kernel not having the same GPS wakelock issues. I went back to stock because I wanted something really light, what I ended up doing is using Titanium Backup to uninstall anything that showed up in the apps drawer or task manager that I didn't need. That made everything really nice and fast. Of course you could do the same thing with Eryigit. That might be my next move. Or maybe just try the custom kernel with the Stock ROM.

Yeah. I'm currently using Paranoid Android and it only charges to 80%. When I unplug and plug in the device it starts charging again.
I love the Galaxy Player 5.0, but it really bugs me the way Samsung so often completely abandons its customers past the point of purchase. Charging problems, bogus battery level readout, GPS off battery drain, screwy unusable GPS compass... and forget about Android updates. The US version never even got 2.3.6. I really wish there was a viable non-Samsung alternative to the 5.0, but there doesn't appear to be anything else out there that's like it.
I've had my G5 (RS988) for 3 days and my biggest issue thus far has been battery life. I looked at which processes are draining the battery, and to my surprise "Phone Idle" is the #1 offender, consuming over 20% of the battery.
Besides calls/texts, I mainly listen to music (media player, not streaming) on my commute to and from work, as well as browse the internet.
I fell asleep with my battery at 50% and woke up to it at 25%.
I'm running OS 7.0 and Software Version 21c.
I was checking out aftermarket batteries last night and there are several choices. Most of then are rated much higher than the stock battery. Has anyone tried any of these with positive results?

There are no batteries with greater capacity than LG's original one. These are cheaters claiming 4300mAh etc!
Original battery is 2800mAh, that is all that can fit in that physical size, that is the energy density that's possible right now. LG would have loved to put a higher capacity battery if it was possible.
Most possibly you will get much less than 2800mAh from those who claim the ridiculous high capacity than those who sell batteries as 2800mAh (even these are probably less than stated).

What's aod?
I was able to cut the phone idle battery usage by like 60%+ thanks to someone on Reddit. They recommended resetting the permissions on all the apps. The reason being that all the permissions got grandfathered in on the OS 7.0 update and it was somehow causing insane battery consumption. Hopefully I'm explaining that correctly. If you haven't heard of this fix and want me to find the link, let me know.

Hello guys,
So the other day I was messing with thermals and I flashed a thermal that basically removes entire thermal throttling. Because of that, I was able to charge my phone at 33wat constantly for about 20 mins. The charging speed was super awesome, but I'm wondering is it safe to do so constantly? When I was back on stock settings, the charge speed would randomly fluctuate b/w 10-18 watt but with no throttling it just constantly remains on 33watt.
So again is it safe to keep charging my phone on these higher voltages constantly?

Not knowing enough about this, I'd assume it's not safe and that heating of the battery would be the issue and would lead to your battery being cooked over a series of charging cycles, but I see your point temperature was not excessive (34°) - I'd advise using an app to record moment by moment charging temperature
Assuming you didn't have your phone in a pool of cooled mineral oil during charging I'd assume that you've just become a test pilot. Let us know what happens... [consider also the possibility that your house might burn down]

OK thanks for your insights. Yes I did some research on my own. Particularly from battery university (yes that's a thing, a whole website..) and I learned that as long as your battery temp doesn't hit 50c you can do whatever you want because in the end your phone only ever draws enough power that its circuitry was designed for. So that information was enough for me to continue my journey into hotter waters.
So far, during charging from 49% to 80% my poco only took about 17 mins to reach there and right when it reached 80c that I saw it start to throttle a bit so by the time it was 82, the watts came down to 25-28 range. So I guess that's hardware throttling in effect since I have already got the software ones removed? And anyway during these 17 mins, while the ambient temp at my place was 32c, the battery temp soared as far as 43c. I believe I would frequently hit the same temp even when I had all thermal enabled running on stock setup. So we can safely rule out that it didn't happen because of not having thermals but just because the ambaint + charging had their own way.
Lastly, I would continue doing this for few more days checking under air-conditioned room next and see how it goes. For now I'm sticking with 20-80 battery rule because that's supposed to be the safest thing in the world of li-on batteries.
Normally quickcharge will keep stuff safe so it will adjust accordingly.
If temps would get over 40-45 deg. c. over a long time it would take a hit on the 'life' of the cell.
Charging slow and between a range of 10 and 90% will help cell life for sure.
what kind of adapter were you using to get 33 watts? most i've seen on my phone is 22 or something watts
also, what font is that if you don't mind me asking
mine does 33 watts too ??

Whats the deal about f2fs I keep seeing this pop every once in a while but never got enough details on it. Since you are using it, can you educate me what it's and does it even make any difference?

It's a file system for android, and yes it does make quite a decent (not like huge) difference when you load up apps (f2fs is usually used in the /data partition) basically apps open faster and it makes the phone feels snappier.

But, how long does it take to reach 49% from 0% or from 20% as you say you follow the 20-80 rule?
Removing thermals is not a good idea, I'm not an expert but I get more fluid experience playing CODM , capping the max speed of all proccesors to 1.7ghz , and keep the phone charging at low voltage. I can play for hours at 60fps and the battery never hits 44c. Removing thermals and processor's cap, I would have a great 15 minutes of game and then it would be very hot and hardware throttle, to the extreme of even get only 20 frames /sec or even less.
All that heat is bad for battery and the components. The battery will go bad faster, inflating in worst cases, and the IPS panel can get permanent ghosting. I know this from previous devices poco included. I do gaming for hours. Removing thermals + gaming at high brightness is bad.

Um, you don't just remove thermal limitations and charge like yesterday.
That is useless and in some cases counter-intuitive.
You highly decrease the temperature to 14 degree Celsius to 26/28 Degree Celsius and charge in that.
However as you say, if you're doing high intense activities that use a lot of hardware, which generally heats the phone, then having a heated phone for extended periods of time *might* be bad for the battery, well having any electronic device heated is bad for the internal circuitry. I have a personal experience with this.
That said, as long as you're using your phone for mild to medium intensity activities like watching multi-media applications and surfing, calling, etc removing thermals will have no significant issues and not reduce the battery life because your phone is mostly never going above 35/36 degree Celsius.
Or if you can, remove thermals whenever you're charging and put them back on whenever you're not.

alifarhad said:
Hello guys,
So the other day I was messing with thermals and I flashed a thermal that basically removes entire thermal throttling. Because of that, I was able to charge my phone at 33wat constantly for about 20 mins. The charging speed was super awesome, but I'm wondering is it safe to do so constantly? When I was back on stock settings, the charge speed would randomly fluctuate b/w 10-18 watt but with no throttling it just constantly remains on 33watt.
So again is it safe to keep charging my phone on these higher voltages constantly?

Hi,
So I've been using an app called Battery Charge Limit from the Play Store (https://play.google.com/store/apps/details?id=com.slash.batterychargelimit) to limit my battery charging upto 80% using root access. This was to increase the longevity of the battery.
Worked fine on Oreo, but now for some reason it doesn't seem to stop the battery charging at 80% on Pie. I was wondering if anyone else has encountered this issue and has found a fix/workaround?
I know its probably better just to ask the app developers, but I was just wondering if anyone else is having this issue as I also have access to an S7 Edge on OneUI Pie and it doesn't seem to have any issues.
Thanks

I do not see any sense in such charging settings, the V30 with 100% notification is still charging for 30 minutes with low current and then only reaches a physical 100% battery which is to save the battery. As the program disconnects charging at 80% it will be physical about 70% = 2/3 for battery use. You probably don't discharge the battery less than 30% because you will "damage it". Then use 1/3 charging it 3 times at the same time as I do ... So think about whether after these 4 years you won't have a more dead battery than I, kids, I charge 15> 100%.
Yes, the answer is simple, charge up to 100% and disconnect immediately, just like LG limits charging to physical 95% so that the battery does not lose capacity.

Fair enough. I simply limit it to 80% as from what I understand the majority of battery wear happens between 80-100%, even if it is charging at a much lower voltage and current.
Even if the phone doesn't show the true values of physical charge, a physical 70% charge is enough to get me through the day and I don't worry too much about how much battery I drain so only put the phone back to charge when it's at ~5%. So only charge the phone once a day.
Even if it may/may not make a difference to longevity it's worth a shot. At best it'll improve the lifespan of the battery, at worst it'll do nothing with normal degradation.
Maybe in a year or so when 80% charge can't get me through the day I might drop the limit. For now it seems worth a try.

Just for your information, deep discharges are also not very good for Lion batteries. Discharging to 5% regularly is as bad, if not worse, than charging to 100%. The optimal is to always keep the battery level between 40%-80%.
I am not so sure if that will make any visible real world difference since most people don't tend to keep their phones for too long. And since that limits the effective battery capacity too much, I would suggest that you don't worry too much about charging/discharging too much.

To answer your original question, the same feature works as intended on a different app (AccuBattery) on my phone, stock unrooted open EU H93030b. So it looks like your problem is not the OS but the app.

Yeah I am aware that discharging to 5% can be just as bad for the battery. But even if I charged to 100% I would still use the phone till there was only 5% left. So I just thought might as well try to limit the charging and see if it makes a difference on the long run, since 80% gets me through a the day anyway.

Thanks for your help! I did try out Accubattery and yes it detects when the battery is at 80%. Just wish it could set limits with root access as well.
In any case, I seem to have found a solution now. There's a Magisk module called Advanced Charging Control (ACC). This seems to work well and limits charging to 80%. It also has a companion app that you can use to set your own preferences and limits.
I've linked the relevant thread below, might be useful to others.

Your doing more worse then good letting the phone go to 5%. That app will not do ANYTHING for you.
Sent from my LG-H932 using XDA Labs
I find ACC works well at stopping the chargeing at a certain % level.
Hoiwever then while still connected to usb it draws power from the battery - not good.
Battery charge Limit on Oreo stoped charging and used then power from usbb onwards while still connected.
I wonder how ACC stops the charging on Pie, i.e. with what control file. Has anyone got an idea?
I foudn out that the switch is /sys/devices/platform/lge-unified-nodes/charging_enabled. This starts/stops the chargi8ng.
Unfortunately, on Pie, when this is set to disabled from then on power ist not drawn from the charger but from the battery.
Is there any other switch / wax to prevent this?
Ich want charging to be stopped and from then on power to be taken from the charger while connected to it.
Here are the paths to the CTRL files that I've found to work with the two ROMs that I've used recently:
Havoc-OS wired and wireless: /sys/devices/platform/lge-unified-nodes/charging_enable (no 'd' on the end, unlike what bladecgn gave)
Lineage OS wired: /sys/class/power_supply/battery/charging_enabled
Lineage OS wireless: /sys/class/power_supply/dc-wireless/charging_enabled
One quirk that I've noticed is that, on wireless, the app ignores the "Recharge below" setting and starts recharging as soon as the percentage drops just 1% below the max (ex. if the max is 80% and the charge drops to 79%, it'll immediately recharge back to 80%, even if "Recharge below" is set at 76%).
For the record, the ROM that I'm using is LineageOS 17.1, so the app definitely still works on Android 10.

Were you able to figure out how to use only power from the charger instead of the battery, @bladecgn?

Stock Pie doesn't have the /sys/class/power_supply/battery/charging_enabled file, but it does have /sys/class/power_supply/battery/battery_charging_enabled. Would that work?

I don't know. You'll just have to try. It's a process of trial and error to find which path works with which ROMs.
