Hey,
So I used to have the Titan. Often I would take out the battery and just use the phone without it in *edited* while plugging into the wall, in order to save the battery for later....or to avoid the battery from over heating and shutting down services on the phone.
Pretty simple:
Is there anyway to program the phone to stay on with the battery out *edited* with the wall charger in? Seems like if on the Titan you could do it, here you should be able to as well?
Edited for xander
just because you were high and seeing stars doesnt mean you can operate a phone with no power unless you have a wall charger. although you failed to mention that so this thread should be kaput.
the above reply was almost as bad as the original thread post.
giggly
I definitely should have read over what I was about to post.
anyhow, any solutions?
Mine works just fine without the battery in if I plug it in......... no mod needed??
You do realize that once the battery is completely charged it is no longer charging. Just about EVERYTHING Li-Ion is "smart charged."
The batteries would burst into flames if continuously charged.
I have had a VERY low battery (5% or lower) and plugged into a 500ma power supply (typical USB charger, not HTC factory) and while really taxing the phone (streaming skyfire flash videos back when Hulu worked) and it would only charge the phone 10 percent in about 20 minutes. Sometimes it seemed it wasn't charging at all. The phone is really sucking some current, cellular radio downloading large amounts of data, processor is blazing running skyfire.
Now with the HTC factory charger being a 1000ma (1A) power supply it could obviously supply enough power for the TP at "full demand."
Goes back to the original question.
WHY?
It isn't serving any benefit. Li-Ion does not have a charge "memory" like old NiCd batteries or NiMh. Yes there are a certain amount of charges the battery can take but again, the phone is a smart charger. Once the battery is at full capacity (you want a charged battery right?) it no longer is charging. There is no battery degredation occuring.
to simply answer the op and not beat him to death with words, there is an easy answer to the question... no, there is no software to be able to do what you want for 2 reasons. one, there is extreamly low demand for the application. people here don't generally spend a week or 2 making a program to make one person happy. they'll do it for a hundred people though. two, i could be wrong about this reason but i don't believe that the hardware will allow it. it's designed to have the electricity run to the battery first, then the phone draws the energy from the battery for use. to my knowledge the phone doesn't have a way to be able to use the energy from the charging port directly. sorry champ, the only way that you are going to get this done is with an electrical engineering degree, soddering iron, and the circuit blueprints themselves.
to simply correct the poster aboive and still think about beating him to death...
yes it is possible, no you do not need extra software... and yes the hardware supports it... Im sorry I personally don't know how to do [email protected]: But if you post over @ PPCGeeks im sure they'll figure it out for ya.
I know it's possible for two reasons... If your phone is plugged Via USB in the bootloader, you may take the battery out. Also, on a ROM that I had installed previously my phone froze for about 2 mins and the battery was blazing so i took it out... To my surprise it was still on (i was tethering) and working perfectly! ZOMG...I love people who answer unknowingly...
For the person who said the smart remark about the lithium battery, im sure the OP knew that, but requires the phone to work with the battery off after he was done charging it... This would let him tether or do what it is that he needs endlessly without worrying about the battery overheating...
In other words, if you're not here to help, then sthu... Dont ***** about his question, dont insult him... Either help, or move on...

Uh, I tell you what there buddy. I'll take your post seriously when you can learn some grammar. For all I know I'm talking to a 12 year old know it all who ALSO doesn't know how to keep his mouth shut.
I WAS offering help, by telling him that there is NO POINT in removing the battery. I implied NO disrespect with my post.
If you are referring to problems with certain software causing the phone to overheat and restart/lock up... again that has NOTHING to do with the battery. For example WMWifiRouter, or streaming high kbps video.
The wifi/cellular radio/processor is what is generating the heat.
If you're not charging the battery (IE battery=100%) then there is NO HEAT GENERATED. The heat is not coming from the battery.

haha whatever...
what a poor redneck duck
Double Post...
Ok smartass.
Explain to me how tethering your phone with a charger plugged in and the battery already being charged causes the battery to heat up.
Think long and hard about your answer. Go ahead and post with your "mAd tyt3 h4x tyP1ng s|<Illz DAWG!"
I'm a ****ing electrical engineer, with a Masters. Take your poems and books and literature discussion groups and go **** yourself.
Only way that is going to happen is if the phone is consuming more current than the charger can provide.
IE: The phone is consuming 650ma, but a typical USB charger can only supply 500ma. In that case then the even simpler answer is NO you cannot use a charging adapter with no battery plugged in.
If you're a car guy here's an even better analogy.
Your car has an alternator (generates current) and a battery (stores current).
If your car's alternator is rated at 100A, then at a specified RPM your alternator generates 100 amps of current.
However, at idle your alternator may only be generating 40A.
If you're sitting at a traffic light and your headlights are on, heater blower fan is going, window wipers are on, heated seats are on... you're consuming more power than the alternator can provide. So the car is pulling current from the battery. The second you leave the traffic light and accelerate and your engine is spinning fast enough that the alternator can generate enough current to supply the demand and charge the battery.
Easy buddies!
We all are here to share knowledge we have to each other right?
Plz. don't let a small thing cause big problems!

as hippy-rific as navi_mappers statement is, i have to agree with him. people are getting a little too angry about this. it was a simple question. unfortunatly it has been answered in contradictory ways. one thing has remained true in most posts though: there is little reason to do what he was trying to do. i believe that he can take that and walk with it. there's no reason that we (as educated and intelligent people) need to resort to name calling and slander. i'd like to think that we are a little better than that. so shut up, stop *****ing and answer the mans question with intelligence damn it! i'd expect this kind of stupid crap over at crackberry.com, not here.

Thanks for those that replied in an appropriate way.
yeah,some may need therapy in this thread...
haha yea i was havin a bad week... my bad guys
First of all, hello to everyone. I have been reading through a lot of threads here in the last few weeks after getting my HD2, especially the ones about battery life.
I have never owned a smartphone, so I have no comparison but I'm barely getting through 1 day of use when fully charged! And I'm not even using it that much yet, Wifi is off, no data transfers, just some texting and calls. I have installed Bandswitch and Battlog, didn't really help though.
Got the phone brand new (T-Mobile US) and haven't done any major tweaking yet, it's still pretty much stock with a few programs that I installed so far.
Do you guys have a similar experience or is it completely different? I love the phone, but if I dont even get through one day of use (and I want to use the phone in the future, not just for surfing but for music streaming or web browsing), I would have to bring it back.
Any help appreciated!
It's just something you have to live with, buy a spare battery, or the extended battery, flash a lighter ROM, adjust screen brightness turn off push e-mails etc etc.
I can get 2 days battery from very light use. i.e. a few texts and calls a day, no Wi-Fi, bluetooth or internet browsing. That's just how smartphones are.
So how do you do it on a daily basis?
My battery is fully charged in the morning and lets assume I'm using the phone for what I bought it for - some music streaming, gps here and there if I need it, some web browsing, calls and texts etc.
I haven't even started using most of the features of the phone and my battery has died twice on my already while I was out at night.
How can that be normal or acceptable? I can't charge my battery every 6h...

Maybe you shouldn't have a smart phone? Battery technology is ****, it's a shame, but it's true. The only thing I can suggest is a spare battery, I carry one everywhere.
I generally watch an hour and a half of video a day on my phone, text, call, use the internet and I can still make a 9 hour day with 40%+ battery left, and just incase I am out and about in the evening before I have a chance to get the phone on charge I have the spare.
But with that said half hours charge from the mains will give you a good 30% topup I very seldom have to swap the batterys and I use a pretty juicy ROM.

or maybe not
Given his kind of use, 2 days should be normal. Right now I'm squeezing 3 days out of this battery, and that's only because I swap it out when it's at 10%, otherwise it could be a little longer... and a few calls here and there is not the only thing I did with it... it's still my work pda after all
Since it's pretty much stock, unless it gets better with time (the first recharging cycles are the worst) and even after a hard reset it won't get better, it probably is something wrong not software related.
Install battclock and check the standby battery drain, shouldn't be much higher than 4mA, up to 7mA could be normal, any higher than that, especially if significant, and you've got something wrong, and found the cause to the short battery life.
First off, buy a couple of cheap oem batteries from here...
Now, these eBay batteries have performed slightly better than the original battery...
Some of us smartphone users are so used to poor battery life we have power charging cradles at home work and car just to keep the charge up... And have spare batteries every in case of emergency...
I take my phone off the charger at 6am to go to work... My avg day is 6-10 calls, 20 reminders, an hour of UNO, an hour as a wifi router and I return home at 5pm with 50-60% battery life...
they are trying to make batteries smaller and thinner so they can make the phones thinner and smaller so battery life is compromised. But you do need to give it some time to settle in.
Back up batteries and cradles to charge them are cheap and an easy solution. So are extra chargers to keep at work, in the car, etc. Most people can charge their phone at least an hour during the day and that should give you all you need.
The only smartphone that I didn't carry an extra battery for was the moto q9c, because it came with an extended life battery. But on these phones, that probably isn't the best option.
So what did you guys do to improve the battery life of your HD2? Are there any specific programs (I heared about G-Profile) you are not supposed to use or did you guys just deinstall all the T-Mobile Apps?
If I can just get 1 day of actual use out of it I am OK with that. I just dont want to have die every second or third day if I use more often than normal...
Any suggestions or may tests I could do? I feel like I could stream music on Slacker for about 90 Minutes and the battery would be dead...
EDIT: Just did Battlog for about 15 Minutes, my phone uses between 15ma and 31ma when in standby. So where do I start, how do I find the culprit?
I love huge screen HTC devices and Im a power user, so my solutions for power issues are:

Software and the end-user are the cause behind battery drain. I've got 2.5days out of moderate use so I don't think it's the hardware at all.
Methods for testing battery consumption and proof it is typically software related
Hi,
At the risk of looking like I'm trying to hijack this thread, I started a discussion on this particular subject a while ago as feedback on my finding after reading almost all the threads I could find regarding battery use on the HD2. Lude219 is 100% correct, the issue is always software related (yea, I know there might be exceptions to the rule) and my phone was a prime example of that.
See the thread below that explains how to measure your battery consumption, has logs and screen shots from users you have high consumption and also people who have systems where battery life is more than 48 hours so that you can compare your results.

I'm also sure it's software related. My phone would use app. 2% overnight with all connections closed. This i tested over months. Then suddenly without me changing anything drastic software wise, it pulled 5% per 3-4 hours. So after going thru all the cleaning routines nothing helped exept a good "ram cleaning" . Somehow or other the phone starts processes over time wich consume alot of power. One would have to look into it with a process manager to find out what exactly it is. WinMo seems to be quite sofisticated looking at all the running processes. So my view is , keeping the system tidy might be the only way to save the extra power.This is where the huge diffrence to other platforms seems to be, it can take quite a while until you have configured your phone the way you need it. I am useing the stock rom 1.66 German
thanks you guys for participating and sharing your thoughts.
But now, here is a thinker:
Last night, I let my battery drain all the way to zero and then recharged it at night. The only other thing I did was installing BSBTweaks and Touch X Taskmanager. I also changed my Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before).
And I couldnt believe what I was seeing, I took my phone off the charger this morning around 8.30am and now at 7pm I am still at 84%!!! I did not use the phone heavily but sent and received a few texts, made 1 call and played around with it for a little bit. Similiarly to what I did in the beginning after I got the phone, but then the battery had almost died at 7pm!
I am super happy and hope it stays like that but cannot explain why all the sudden it is that different...
Hi everyone,
This is a very usefull thread, for me it is, thanks to everybody that answered.
regrding the last post, a noobish quesition is
”Bandswitch Settings to turn off data when not used and put it at 60 sec (instead of 500 sec before): how do i do this?”
I remember stumbling upon this setting the day i got the phone and started viciously going through it.
Somehow it didnt store in my memory the path i went that day so i can try doing what the man sugested.
So if anyone can lay a hand, much obliged.
Regards
i lost 12 pct over night in 9 hours with my radio turned off last night and only gmail and texts were open...
with battlog how do i do the test so it stays in standby? it keeps turning the screen on and off when i run benchmark
You may want to flash a new radio. Try a new one each day and measure battery life. I use radio 2.12.50 and have had a good experience.
yeah but with my radio turned off the radio shouldnt affect it shoudl it?
i use blackberry to stream pandora radio thru aux for about 8 hours a day and it still has 2 bars left after that.
HD2 just sits there and kills the battery lol
what kind of phone is that when you have to disable all its functions every time you dont use it?
seriously this is called unfinished product or poor design, that is beeing sold to customers as a next best thing.
you guys can argue with me all you want. i heard many excuses from users advocating the companies. such as. if you dont like this than pay more for a better product. well HD2 is a better product, its a 500 dollar phone damn it.
but you dont realize that even the "better" products suffer from same underdevelopment syndrome.
companies spend millions on consumer research and consumers spend millions on **** they dont need every year. cows eat grass, consumers eat garbage made by big companies.
where are the better products? they dont exist because it became "normal" to have a faulty OS or for your phone buttons to fall off, or battery to explode.
companies worked long and hard to make consumers get used to the idea that garbage is just a part of life, and worked long and hard to minimize costs of production, and cut corners.
which corners?
the final QA testing that is not beeing done by a company, so they can release the phone 3 months earlier, the consumers pay for the phone and test it.
we work for the company and we pay for it instead of getting paid.
the phone breaks oh how sad ,
company takes note(dont use this cheap glue or the buttons fall off, get a lil more expensive glue next year)
so they use better glue and cut another corner and we buy another "new and improved phone" and this time screen goes dim oh dang not again...and it continues.
do you disconnect your car battery every night so it doesnt die? or when you buy a lexus do you drive with your AC off because it cant pull the car around when ac is on same time as the stereo?
Did HTC change the way devices operate when plugged in?
With the original evo 4g, it would run off the battery even when plugged in. Is that still the case with their newer devices (including the lte)?

I don't know the answer, but a fascinating question. Laptops don't run off the battery when charging (at least I don't think any ones I've ever owned do). So why should phones? They're basically little computers now anyway. I suppose we'll need a manual to know the answer, or an HTC rep.
While I agree with your assertion above, that was not the case with the original evo.
As is recall, this is demonstrated by using battery monitor widget or similar, with history enabled. The data would indicate that once the phone reached 100% charge, it would begin to discharge until about 90%. At this point it would start charging up again (until 100%) and the cycle would repeat.
If the phone is running off the charger while plugged in, the battery level should remain at 100% the entire time. Sure there were kernels available that would change the charge rate or thresholds. Anyone with an evo 3d care to chime in?

That seems rather silly - what if you grab the phone off the charger when it is just down to that 90% marker? It will show up as 100% I presume, and then drop rapidly down to 90%? Hmmm... No wonder those SBC kernels are so useful!
It's the same reason most new laptops give you a battery health option that only charges to 80% if you keep a battery at full charge for an extended period of time the cells will overheat and eventually lose some of their charging ability kinda like when you use a float charge on a lawnmower battery it's on a constant charge and discharge to keep the battery healthy same rule applies here.
Whatever they do/did, I hope it's well thought out, considering the battery is not removable. Once the cells degrade,...phone is shot. A bit disappointing. I'm not here trying to fight about nonremovable battery and how long it will last, and ability yo swap out batteries. But the idea that battery degradation (which is inevitable) = shot phone DOES give me pause and concern.

Even after a year, there is noticeable diminished battery capacity. I've had the seidio 3500 in my original evo since about feb or march of last year. Fast forward to same time this year. I'd say it easily lost 20-25% capacity. With my typical usage, I could go for up to 4 days without having to recharge (yes, light user). Now, it's 2-2.5 days. I was bothered by it enough that I did an rma. Seidio said that's normal wear and tear. Fortunately, the credit card I used had an extended warranty feature too, so that's what covered it.
There will likely be a tear apart video/howto posted eventually on the evo lte. Although the battery may not be typical user replaceable, i'm confident it is possible to open the device with minimal damage.
I'm sure there will be a way to switch batteried, you'll just have to go to a phone tech probably. I'm not worried anyways, I'm still using my stock evo battery and it's still going strong

I'm sure you can fork over some cash and get the battery replaced. I wouldn't lose any sleep over this. iPhones have survived with non-removable batteries for many years (although I always used that as a "con" in my comparisons between Apple and Google's respective phones).
My Evo 3D will discharge to 95% then back to 100% and repeat. It is done to keep the battery in good health longer.

Bump since no one has given input after "release". Very interested if we will still need to do that "turn it off, charge, unplug, charge, repeat" thing.

This is true, But iPhone users have no choice. So they get used to it.
Android, at least for now, has choices regarding removeable batteries.
IPhone users also have a 3 1/2"? size screen, which they got used to.
I'd Never purchase an Android device with that size screen, even if it was available. I highly doubt they'd sell many of them with that size screen.
Reminds me of when I thought my HTC Touch Diamond's screen was so large, compared to my previous clamshell devices prior to that lol!
It was such a nice screen for its time, just like the iPhone was a nice screen for its time, but that time has long passed, except for iPhone users :-(
I've heard several different opinions on this. Condition or not to Condition the battery.
Do we need to condition this thing?
How are you doing it?
What kind of results are you getting?
Thanks in advance.

Li-ion
The battery is lithium Ion so you really shouldn't have to from my understanding.
People do even tho is not necessary, for some reason I don't but after a few day battery has gotten better
Sent from my SGH-T999 using Tapatalk 2
I mentioned this earlier -- I know it's a li ion that shouldn't need conditioning but when I first got mine my battery life was absolutely horrible. I went through two full discharge/recharge cycles and it seems to be much better now.
Currently 11 hours on battery, 50 minutes screen on, played a couple of games, downloaded a couple of apps, 15 minutes of voice calls, and battery is at 80%.
The way it was when I first got it, I'd probably be at 40 or 50% right now, if not even lower.
I'm also running juice defender and have stopped using the gmail app because you can't set the sync interval on it. Instead I've been using the built in email app and have it set to sync every 30 minutes. Not sure if any of this is doing anything but my battery life is definitely better than when I first got the phone. At first it was so bad that I came very close to just returning the phone.

That's true for me as well now that you mentioned it. First day, I got about 4 1/2 hours with it before i was down to 10%. I was shocked! Each day it has gotten a little better. Over the last 36 hours it has last a full days before a charge. It doesn't really make much sense to me that they are li-ion which shouldn't need conditioned but it seems that we do need to do this. A friend suggested I condition it when I got it and before I started heavily using it, I guess he was right.
Li-ion batteries don't need conditioned. Any signs of conditioning you see may be some sort of conditioning/learning of the OS.

See this kinda stuff freaks me out. I had one decent charge so far, had the phone a week, have been doing full discharge/charge the whole time. Sitting at 38% right now on 16 hours, about half of that was asleep with power save on (its been dropping 20-30% overnight) and only 48 minutes screen time. I dunno how long it should take to improve but it seems like its not taking this long for anyone else.

How long do you usually sleep for???
Seriously though, 20 - 30% overnight sounds like a lot. I tested mine and it dropped about 8% in roughly 7 hours of zero use while I was sleeping. I think even that is a little excessive but I can live with it.
Have you tried running something like Juice Defender? It seems to have made a difference with mine. When I got my S3 last week it was about the same as yours. I did a couple of complete discharge/charge cycles, installed juice defender, and have been going into the task manager and app manager and turning off all the crap that doesn't turn off automatically. It has made a difference.
Oh, and I also did the APN trick to disable LTE. Not sure if that has made any difference but with everything combined the battery seems to be doing a lot better than it was at first.
Don't "they" say that you should not use task managers as they don't work well with the phones? I'm no expert here, so don't quote me, but my understanding is that the One S and Siii owe a lot of their excellent battery lives to their own internal task managing.
Correct me if I'm wrong here.

The internal task managing is the reason you shouldn't use 3rd part task managers. That's the whole point. Android has done this since 2.0
Having said that, there's nothing inherently wrong with killing a task that is misbehaving... most things that say not to use task managers really mean to not (a) turn on auto task-killing, or (b) kill tasks across the board, albeit manually, under the false impression that freeing up RAM is a good thing.
When you guys say full discharge do you mean draining the battery till it shuts off or going down to 10%, I was under the impression that fully discharging would harm the battery.

I discharged it till zero. Then I turned the phone on and let it shut off again. I did this until the phone wouldn't even try to turn on any more.

Doing this enough times has the potential to damage your battery. Leaving it at 2% - 5% will not make a difference in the "calibration" compared to completely killing the battery.
Killing the battery may work for you, but I want others to be aware of the potential of damaging the battery.
Just my 2cents for the day.
Here. Is a link to battery charging for Li-ion. I have another site that is great in explaining these things. I have a couple of R/C trucks and this info is great to know and have. The same applies. To our phones charge rates. I would hope that when a dev makes up or mods a kernel that they have a basic knowledge of charge rates and the rest of the equations. Foe our batteries this is literally. Life and death. It could also cause a phone to burst into flames. Especially. If we use after market batteries that have poor protection circuitry in them.
I will find the other link later and post it up here to give a possible better understanding of these things. But, try not to rely on me as I tend to forget things a lot. Car accidents will do that to you when you crush your skull. Any way, GIYF.

You basically only need to do the "calibration" once. And the phone has limits set that will neither undercharge nor overcharge them.
edit I think heat is your batteries worst enemy.

This is the WORST thing you can do to a Li-Ion battery. I mean literally you can lose 10% of its life from doing this or even cause the battery to stop charging at all.
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.

Seriously everyone should spend a couple hours on that site at some point. Half the information will probably be way over your head (or at least it was mine) but there's enough good information that even half of it is definitely worth learning.
Here is the other site that I was talking about. Though it is for R/C battery packs it should still grant a measure of understanding to the workings of these batteries.

Take into account though. These batteries have circuitry. Built into them to prevent you from truly discharging. It all the way. That doesn't mean that it can not discharge all the way. Things like humidity can play its roll in taking a Li-ion or Lipo battery past the kill zone point. If you know that you will not be using the battery for a good period of time or it is strictly an in case of an emergency battery. Place it into a plastic bag and suck out all of the air that you can and seal it. A zip lock bag works best. Place it in the refrigerator or freezer. There is very little moisture. In there. And what ever moisture makes its way in when you open the fridge. Or freezer will not have time to get into the zip lock bag. The lack of moisture slows the discharge process down especially in the summer. Also the chilling of the battery's chemical. Compounds slows the molecular interactions down. Its a helpful two fold process.

I have a Tasker action that does this automatically 5 minutes after rebooting.
If only there was a way to use that without root :-S
What would be the purpose for this.
I always charged to a 100% and never had issues on my devices.
I use the adaptive charging overnight and think that will help with battery life.

If you do some reading you will see that charging over 80% and draining under 20% will significantly shorten the lifespan of your battery. This is important for those of us that have devices not sold in our country so getting replacement batteries would be very difficult and expensive. I have phones that are more than 9 years old and still going fine if charged like this.

If you would have read the correct information on this subject. You would know that this not true for today's battery technology.
This is nothing but a myth.
You will have a better chance looking for Bigfoot.
Why waste 40% of your battery use....

On the contrary. The most recent phones attempt to limit the time that they spend at 100% exactly because it's so bad for battery longevity. Having options like the OP's approach just gives users more flexibility, should they want more control than, in this case, Google's adaptive/AI approach.
And it's not 'wasting' 40% of the battery. Keeping between 80% and 20% just optimizes battery service life during those days you only actually only need 60% of it's possible capacity. When working from home that's often the case for me. I actually tend to use ~30% of the battery in a day. Better to charge it up daily to about 70% than all the way to 100% and let it go down to 10% over 3 days. If it's easy to do, why not?
Not quite the same, but EV design also has their batteries normally operating in the middle range so as not to compromise their service life...
Definitely not myth. The only myth is that lithium cells exhibit a memory effect and need to be deep discharged and fully recharged periodically to maintain their capacity. It's actually bad for them to do this! The only reason to do this would be in an attempt to recalibrate the software for the battery level gauge (at the cost of a little damage to the battery each time you do that).

Most folk don't notice reduction in battery capacity until it becomes severe. For example, a friend claimed it wasn't a problem charging his iPhone to 100% ritually. When he checked the OS, it said his battery capacity was 80% of what it was when new. He said he hadn't noticed it affect how long the phone lasted.
If your usage is such that you can predict how much capacity you need, you can choose to charge to 100% only those times you will actually need that capacity. Other times you can look after the battery so it's able to actually give near on 100% for longer, those times it's important to you.
Others who keep their phones a short time or are comfortable with the cost & inconvenience of a battery replacement, or simply don't care, don't have to worry....

This all maybe good if you are planning on keeping your device for a few years.
Most people buy a new device every other year. If not once a year.
... and if you really want to knacker the battery, heat it up too!
Worst case scenario - using a sat nav app on your phone in the car on a hot day with the phone plugged into a car adaptor. It's going to be sitting there at elevated temperatures, possibly with the sun shining on it, whilst being kept at 100% battery....
I'm only a customer (and have no other affiliation) and like to tinker, so I got one of these for use in the car to limit temperature when charging and limit max charge. Not cheap, but ok compared with the cost of the phone https://chargie.org/
I'm sorry, but at the snails pace this phone charges I'd be very surprised if charging it to 100% every night will make any noticeable difference in the long run. I had a Xiaomi Mi10 Ultra with 120W fast charger. That phone used to charge from 0% to full in like 20 minutes. Now that's one way to quickly kill your battery.
The Pixel uses your alarm to adaptively charge the battery so it should never overcharge it anyway. I'd much rather us all of my battery than use it only between 20 and 80% just for it to last a little longer.
The files are overwritten on reboot so I created a Tasker task to write the values on reboot each time.

On what basis? All the research and tests are based on charge level not charge rate. Fast charging potentially just makes it worse...
But at the end of the day it's your phone. You'll charge it in whatever way works for you.
I feel like this post sort of misses the point. It clearly is aimed at those intending to keep their phones >1yr, it is stated explicitly.
I'm not rooted right now, so I've been using the AccuBattery app. One of the things it does it gives a notification every few minutes when the battery is at 80% or above so that you can physically unplug the phone from the charger. Obviously having this done automatically would be better, but I've been surprised at how well the notifications have worked in my case. Plus, I can always leave the phone plugged in if I know I need a full battery for some reason (ie a long day away from any charging source).

Dumb question but what did you use to write values into those files? Did you use a text editor (with root access) or just termux or something? I tried with the built in MiX text editor but it seems to choke once I open up the file.

I used FX File Explorer (root option). Look for the #. SYSTEM (Root).
I was wondering if changing the file permissions after writing to them to read-only would make the changes stick, but I am sure the OS could still overwrite them...??
I wonder if there's a similar variable to tweak at what temperature the phone considers the battery is too hot and stops charging?

Did a bit of testing and it works fine. A few things I noticed:
1. Doesn't survive reboot. Now that I've set up MiX with pinned folders, I can make the change in seconds. Need to sit down and read through the acc documentation because AccA doesn't work. Would love to have an automatic solution. Miss my old Battery Charge Limit.
2. charge_start doesn't seem to matter. After all, if charge_start is set to 75 and the phone is at 70%, it shouldn't charge. But it does. I've kept mine at 0.
3. Point #2 is kinda beside the point, though, because charge_stop will stop at the set value and stay there. No noticeable increase in temperature from what I can see. Definitely less than when charging.
4. Still shows as charging rapidly when it hits the level. Is it rapidly cycling charging on and off? Or in a kind of micro-current state? Or this may be a true battery idle situation where all power is drawn from the adapter. Ampere and AccA just show "not charging".
Edit: With a bit of use today, it does seem to act like a normal min/max charge deal, so I set it at 75 start/76 stop. Not sure what was happening at first...maybe something to do with the adaptive charging since I still have that on. Either, way, no complaints. With my use case working from home, I have it plugged in most of the day and it'll only take me about a minute to change charge_stop to 100 when I'm planning to go out all day somewhere away from chargers. Not ideal, but still a big improvement. Changes my rating of the thing from maybe 3.5 stars to 4.5.
