The three issues all may cause detrimental heat.
- Rapid charging from 30% to 90%
- Charging overnight for hours once it’s reached 100%
- Discharging fast and below 40%
New features are always nice. As long as you have the option to use it or not.
I personally don’t need it, but I think it’s good if something like this is installed.
I wouldn’t. Better install it first on a spare phone to see how much you like it.
NEVER do it on your main phone or without having some fallback.
And beware: Flashing ROMs can become an addictive habit!

So you think flashing can become addictive ? 
Why is that?
Thanks for the warning though, so I won’t install another Os.
Btw: For everyone concerned about the data-protection-non-google-aspect IODE offers:
I found a way to miminize trackers by installing the new tracking-protection app from DuckDuckGo.
That blocks all trackers and tells me which are the worst apps
(so I usually deinstall them again).

I almost never charge below 40%, and almost never charge above 80%. Has worked pretty great for me so far. AccuBattery can tell you how much “damage” your battery takes charging from one number to another. Might want to check it out.
I use RethinkDNS for that. The positive is that it also blocks ads, and it encrypts your DNS which may or may not be something you want. A bit of extra security for potentially hostile WiFi if you don’t want to go full tinfoil by using a VPN.

The real important thing is to not completely discharge if possible, to avoid deep discharge, and the rest is max. nice to think of. Dont let such dictate your life

Hi.
Well I can see from a graph of values taken from my phone an FP3 with a 2.5 year old battery that the difference in voltage and the SoC below 50% is clearly not consistent with that above 50%.
This indicates that the charge drops rapidly although the voltage doesn’t
The power available, watts{W} is a product of voltage{V} times current{I} W=V×I
Batteries product heat depending upon efficiency, so forced charging or draining is a issue of efficiency.
If the SoC drops quickly whilst the voltage doesn’t it means it means the battery is not performing well which indicates, wear, stress and heat and hence further damage.
But the caveat is that is this battery some 2.5 years old and the onboard monitor says the battery is good.
I will test with a newer battery, but I’m not overly concerned. I often allow it to run down to 30% or lower, whilst I have a friend who has an issue if ti drops below 60%
It’s just a battery 
If you have easy access to charging all day and a cable it make sense to keep the battery above 50% and maybe 75% but then you only have a 25% capacity.
If you are out and about for a day or more then charge to 100%, try a slow charge but be wary of going too low 15% I think has a built in warning.
The QC3 charge system is supposed to have a built in slow charge around 90% but I haven’t seen much evidence of that happening.
My main reason for the post is that charging to a specific level is not the overriding factor. Stress caused by rapid charging is more damaging 78% that a slow charge at 99% but it all depends upon the heat generated.
Apologies if you feel that 20% may not be optimum.
20% is a common low for the user that doesn’t want to pay to much attention and the Fairphone company does recommend that 20% to 80% to limit the extremes.
10% to 90% will suit some better.
The battery is guaranteed for two years without any caveat and should still provide 80% of capacity. Clearly this applies to enough users not have to replace batteries under warranty. heavy users can burn out a battery in a year, others maybe 4 or 5 years.
I’m still using an 10 year old Samsung with original battery, it works and can a few hours doing bluetooth music to a Marley.
Why? Trust me, I have been down that road
Nothing wrong with that, not at all. Just don’t brick your only device. Seen enough people doing that… but considering your blinking, I guess you are safe

Just a heads up recent Apple MBPs (not sure which OS version) allow to charge to 80% based on device usage. So for example if it knows its gonna run a long time on battery on say every Thursday it will ensure device is 100% Wednesday night but otherwise it would stick to 80% while on power. For mobile smartphones (which are usually running on battery throughout the day) this see.s a bitmore complex, but if the user can make the day on 80% to above 0% after a day (minus night of sleep) it .makes sense to stick to 80% there as well. I don’t know whether modern iPhones on recent iOS have a similar feature but relying on third party like Chargie is not ideal in my opinion.

N=2. Here’s 2 more. My wife’s Pixel 3a was abused as well (to the point where battery life was a reason to look for a Pixel 6), and for work I had a refurb which went from 40 to 0 in no time. I replaced the battery with iFixit kit and presto issue went away. So there ypu have it. Two data points where Pixel 3a ended up with battery issues.
Research shows it matters, but a battery on the way out would otherwise be also on the way out a while later. So you are merely postponing required action for a little while, ie. a couple of months.

I notice in both the above posts you mention going down to 0%.
My view is that going to 0% is far more damaging than going to 100% and charging from 0% can also be a challenge.
It depends upon the force being applied that creates the heat and the batteries control of the voltage.
Pixels are known for poor battery performance. Tweaking background processes and widgets can go a long way. I don’t know if the Pixels got better after the Pixel 3 though, didn’t own those. But too small batteries with powerful hardware was a thing back then. Also the reason why I kept my Pixel on that wireless stand all the time.
There was also a meme back then about Pixels. Takes great pictures at night, but the battery will only last till noon 
Also one of the reasons the main camera dev left Google after the Pixel 4 or 5 was released.
But I didn’t deny it could help to be anxious about charging. I just noted that the netto benefits are not worth it. The other persons battery was just as bad. There is probably some benefit, but just not worth stressing about on a daily basis.
I’ve posted elsewhere on this forum that I started using AccuBattery when I got my FP4 and I use the 80% alarm feature to unplug when charging. What has taken longer to change is the nagging feeling in the back of my mind that “I need to charge my phone to the top!” It’s taken some months but I find I am not getting so anxious about ensuring that I have enough charge at a given time of day.
I drive a lot with work so the phone is on a mount and connected with USB-C cable for Android Auto (for Spotify and Sygic Navigation). I usually start the day with 20%-40% battery, rising to 60%-70% by early afternoon and then dropping back to 40% or so by the end of the day. It’s frequent small charges rather than one big charge. AccuBattery reckons I’m losing roughly 1%/month in battery capacity. Assuming that drop is linear, that still gives me 3-4 years of good usable capacity.
I think that big point is that we don’t need to stress about our battery condition too much. It’s good for years, and even if it does conk out quickly, we’ve got a phone that has a replaceable battery.

I started with AccuBattery, too. Now I am using the ACC module in Magisk, that can actually stop charging when reaching a value to be configured. If you have root, ACC is worth having a look, IMHO.

At least on the FP5 there’s a 80% charging limit configurable and also Eco (slow) Charge vs Fast Charge. So there may be hope for FP3 and FP4, too…

FP4 supports charging limiter (native on Lineage OS) AND bypass battery charging if the limit have been reached!
Which means it uses the power from USB directly instead from the battery

By 'supports’ you mean the hardware is capable of it, right? I don’t think the latest stock FPOS provides any configuration options with regards to that on the FP4 yet.
Maybe in october, when Android 13 based FPOS is released for the FP4. Let’s see…

No charge limit under Android 13 
Too bad that this option was not added.

Although you’re right, I think there’s still hope that this function will come with some update as it’s available in FPOS for FP5.

Every day I hope they release this feature. Maybe with A14?
