The iOS option to charge battery to "80% Limit" shouldn't just be for iPhone 15
- LaSombra 3y agoI found this strange as well and have been wondering if there is a hardware constraint that no one is aware, yet.
- metadat 3y agoI have an iPhone 13 mini as my "work phone "and it's indisputably a fantastic, efficient, small phone. However, I am kind of OCD about keeping it between 40-80% charged, which is a lot of manual toil. Conversely, I also have an Android Galaxy S22+ for my personal phone. The "Battery Protect" feature limits charging to 85%. Life is easy with this device and it causes me a lot less anxiety. Really now, why can't Apple enable this for older phones? I don't believe there's any good reason to force batteries to excessively damage themselves. I had a previous iPhone 13 mini I was less careful with on the over-charging front, and the battery performance was markedly worse. Hence the OCD. I acknowledge my neuroticism, but try to curb it within the realm of evidence.
- lukestevens 3y agoFellow OCD-ish charge watcher here. Has worked great for my aging iPhone. What grinds my gears though is the AirPods. I have AirPods Pro that I want to last a long time, but out of the case the earbuds are always 'on' and drain battery relatively quickly (much faster than a phone left idle); put them in their case and they're almost always* charged to 100%. I want to be able to leave them out, off, and disconnected. I almost never need 100% battery in my day-to-day use and there's no replacing the batteries in them once they're worn out. An 80% max charge limit would be great. *They do offer 80% overnight charge protection, but that's irrelevant as I don't keep them plugged in overnight
- geoffeg 3y agoFor a while I had my phone charger plugged into a smart power outlet and a shortcut to turn that smart power outlet off when the phone's battery hit 80%. It would then turn the power outlet back on at 2pm the next day for it to be ready.
- w-ll 3y agoAre we not spose to fully charge our 13 minis? I ask cuz i used to run to like ~5% and then charge but not unplug till it was back at 100% this worked well of my last SE even tho people said i was "doing it wrong". Why cant the phone itself know the best defaults, or is it planned obsolescence? Serious question.
- infecto 3y agoI am mostly speaking from experience with EV batteries. The most wear happens in the top and bottom of the battery state. The battery will last the longest if it sits around 50%.
- arcanemachiner 3y agoThis is true of Li-ion batteries in general.
- lotsofpulp 3y agoIt is not planned obsolescence, just that in the case of a phone, having it at 100% when you are out and about might be worth a shorter life for the battery.
- kryptogeist 3y agoI also use the shortcuts app, but since I dont have a smart outlet it just send me a notification (on my apple watch) when battery charge is above 80%. I also have another shortcut to notify when battery is bellow 20%.
- orev 3y agoMany people charge overnight while sleeping, so that would be really inconvenient.
- mistyvales 3y agoMy Pixel 6 doesn't seem to have this option.. I never looked into third-party apps for it though.
- powderpig 3y agoI highly recommend AccuBattery for Android. I have been using it for a few years now and I saw a noticeable difference on my Pixel 3a XL compared to use on previous smart phones. I now have a Pixel 6 and its nearly 2-years old and the battery lasts well beyond 30-hrs with combined use. https://play.google.com/store/apps/details?id=com.digibites.accubattery https://play.google.com/store/apps/details?id=com.digibites....
- jrockway 3y agoMy previous phone was an iPhone XS and its battery was also completely fine for 2 years. Year 5, I definitely noticed a drop in battery life. If you're planning on keeping your phone for 5+ years, definitely do the 80% thing. If you're on a 2 year upgrade cycle, it probably doesn't matter.
- abdullahkhalids 3y ago> This app may collect these data types Location, Personal info and 3 others
- lazycouchpotato 3y agoI don't think there's a way to manually limit it to 80% within Pixel's settings. If you turn on Adaptive Charging, it'll charge it to 80% overnight and bump it to 100% just before you unplug your phone in the morning. https://support.google.com/pixelphone/answer/7106961 https://support.google.com/pixelphone/answer/7106961
- op00to 3y agoI just use my phone. The battery can be replaced.
- metadat 3y agoSure, as long as you don't mind messing up / sacrificing the IP69 waterproof seal integrity. Ask me how I know *cries softly*.
- bigstrat2003 3y agoI actually don't terribly mind that, mainly because in almost 15 years of owning a smartphone I've never dropped one in the water. I feel pretty comfortable not having waterproofing as a result.
- metadat 3y agoWell, I really like a nice bath at the end of the day. Different strokes and all that, more power to you bigstrat.
- bigstrat2003 3y agoI guess I'm genuinely surprised someone would even want to bring their phone into the bath. I do enjoy a bath rather than a shower on occasion, but I'm just enjoying the soak all by itself. But hey, like you said, different strokes for different folks. I certainly understand why the waterproofing is a concern for you if you're regularly using your phone over water.
- SirMaster 3y agoWhy does it mess up the seal? Are you saying Apple doesn’t re-seal it properly?
- Loggias 3y ago[dead]
- dc3k 3y ago> I am kind of OCD about keeping it between 40-80% charged Why?
- Loggias 3y agoHaving the majority of your usage / charge cycles being based on a 50 to 80% total charged will increase the total cycles (and the battery’s total life).
- gnicholas 3y agoI realize this is true, and sometimes I will charge sooner or stop charging earlier to keep my phone in this range. But most of the time, I just use my phone. After all, what's the point of optimizing the total battery life if you aren't ever going to actually use the battery to its capacity?
- dc3k 3y agoArtificially limiting yourself to 40% of your battery’s capacity to extend its life seems like an enormous waste of effort My last phone spent like 8-10 hours a day on and off a wireless charger and had 88% battery health when I sold it over two years after I bought it
- Reason077 3y ago> "I am kind of OCD about keeping it between 40-80% charged, which is a lot of manual toil." You shouldn't worry too much about going below 40%. Regularly draining it to zero might shorten battery life, but going down to 10-20% won't. > " I don't believe there's any good reason to force batteries to excessively damage themselves." From Apple's perspective there is. Selling replacement batteries is very profitable.
- grepfru_it 3y ago10-20% will definitely reduce cycle life. you would almost double your cycle count by keeping your battery above 40% vs 20%
- Reason077 3y agoThis has far less effect than limiting charging to 80%. If only because you usually spend a short time down at 10% before noticing it's low and finding a charger. Where as phones regularly spend long hours charged to 100% because we tend to put them on chargers and then leave them overnight.
- stealer0517 3y agoCycle count is virtually meaningless. I have a MacBook Pro with almost 1000 charge cycles and it’s got ~93% battery health after 8 years. Lithium batteries are happiest around 40% state of charge. The closer you can keep them to that magic number the longer they’ll last. But leave them fully charged, or even worse, fully dead and that’s the quickest way to kill them with “normal” use.
- Reason077 3y agoThat's very impressive! My Macs are usually down in the 80-85% range after 500 cycles. Do you use any tools to limit charge state other than "optimized battery charging"?
- numpad0 3y agoBattery charging is often controlled in "hardware" and OS don't have full control(else a software crash could easily cause fire). Some hardware implementations can be instructed to stop charging immediately or stop this time at specific voltage, but implementation varies and the feature is often ignored.
- Dylan16807 3y agoWe know the older hardware has that, because the software already controls it on a schedule.
- em-bee 3y agoi barely get through the day with a fully charged phone, and i don't get enough runtime if my laptop is not fully charged. so i'd like to know more about the science behind this. how much does the battery life actually improve by doing this. is the trade off worth the inconvenience of a shorter runtime before i need to recharge?
- HWR_14 3y agoHow is that possible? Even charging my phone to 80%, I can still use it for at least a day. Although my laptop does get a lot more use.
- em-bee 3y agoit depends on how you use your phone. when i am outside all day running errands, checking messages, calls, web searches... by the time i get home my phone is usually on the last % before shutting off. i tend to buy cheaper older models of phones though, that may not have the strongest battery to begin with.
- doix 3y agoI buy cheap android phones with large batteries, it's pretty much my only criteria nowadays because everything else is good enough for me. The only time I get close to running out of battery is when I'm watching YouTube videos on a long bus/train/plane ride.
- whycome 3y agoFull brightness screen is your biggest killer
- Izkata 3y agoIt's for people who only use like 40-50% each day. Going from 50% to 100% puts more strain on the battery than going from 30% to 80%, so limiting the total charge allows the maximum capacity to last longer (in terms of years) than otherwise. And if you do ever need all 100%, just turn off the limit the day before. For me it's a no-brainer: 85% on my current (brand-new) Android phone lasts around 50-55 hours.
- gloryjulio 3y agoThat's the point. Apple wants other models' batteries to degrade fast so that the users can upgrade to 15
- nrr 3y agoDo you have anything other than context clues to go by when making this assertion?
- Gigachad 3y agoThese discussions are always baseless. Could Apple have enabled this feature for all phones? Maybe Would it have provided any use to older phones? Maybe How much lifespan does it actually add? No one knows Did they do this as planned obsolescence? Maybe. There we go, the whole discussion finished.
- gruez 3y agoBut apparently they don't care about future sales from iPhone 15s wearing out?
- lttlrck 3y agoPerhaps they didn't implement this in their BCM, maybe they were so caught up in the cleverness of "optimized" charging they thought it would solve the problem once and for all. Unlikely? Yes, however it's not impossible.... and not the only alternate explanation :-)
- whartung 3y agoMy X (bought new phone in December when it was released) was at 85+% on the battery. I replace it with a 15 because it was dropping off the OS bandwagon, needed more storage, battery life, lightning port getting fiddly. The OS support was the stake in the heart. If not for that I would have looked into getting the phone serviced with a new battery and port, and cleaned up some storage.

- adastra22 3y ago> The difference is that Optimized Charging kicks in only when your iPhone is normally idle, typically overnight. The new 80% charging feature (that’s limited to iPhone 15 models) doesn’t try to be as smart, and simply works all day long. That’s not how the Optimized Battery feature works, according to the help text displayed right next to the feature in the Battery Health settings. I question the whole premise of this article.
- spenvo 3y agoAuthor again, “I question the whole premise of the article” What? You got tripped up on my wording, sorry. But the article's premise is valid, and it's not cool that the top comment on this submission for its first three hours on HN has totally lacked curiosity and come to a sensationalist conclusion. Do you have any actual problems with the article? Could you list them? (You responded to others but not my previous comment)
- adastra22 3y agoDo you have any evidence to back up your claim that there is no hardware or inaccessible firmware difference between the iPhone 15 and 14 which might suggest a different charging strategy and/or limit their ability to roll this out to earlier versions? Or are you just spitballing here?
- spenvo 3y agoHey! (thanks for expounding on your concerns). The claim from the article is that a fixed 'charge to 80% feature' is "likely possible on earlier models". I asked Apple to comment and am curious what they say. We do have evidence for the article's claim: iPhones dating back to at least the iPhone 8 support a feature that limits charging to 80% for multiple hours per day already. It just only occurs during hours Apple chooses via its learning algorithm. I never claim that the hardware is/is-not different; you simply have to look at what is already supported to understand what the devices are capable of.
- spenvo 3y ago
- TheMiddleMan 3y agoRelated: for MacOS, AlDente allows you to set a battery charge limit. https://apphousekitchen.com/ https://apphousekitchen.com/ I've been using it successfully for around a year. It works pretty well sans a couple quirks due to hardware limitations e.g. if you plug in with the screen closed (sleep mode) it will charge fully to 100%.
- timrichard 3y agoThat's true. I evaluated it, but it wasn't of use to me as I keep my Macbook plugged in with the lid closed. I eventually tried this instead (for Intel Macs) : https://github.com/DevNulPavel/osx_battery_charge_limit https://github.com/DevNulPavel/osx_battery_charge_limit I use it to keep my battery level indicator pegged at 70%. Often doesn't persist after a system update, but it's just a quick terminal command to reapply the setting. I use my Macbook in clamshell mode, and I use sleep mode when I'm not using it - receiving power from a Thunderbolt dock. It's handy to pick up exactly where I left off on resume. Plus, I use two LG screens where one of the two doesn't switch on after a cold boot, and it's annoying to unplug and replug to activate it. Sleep mode gets around that.
- mistyvales 3y agoThis happens under Asahi Fedora KDE too.. I think it's the battery controller that works outside of the OS?
- artdigital 3y agoWondering if third-party software like this, when not baked into the OS, will have other longterm side effects. Since it can't really put a hard-stop on charging, can it?
- 1123581321 3y agoAl Dente just sets the charge target via SMC and lower level software handles power draw negotiation. It’s the same thing the OS uses to set the target to 100% or 80%.
- aldebran 3y ago
- spandextwins 3y agoThanks Tesla for bringing about lithium battery health awareness to the masses. Without it I would be charging to 100 every night. And blowing out my battery way too soon.
- KerrAvon 3y ago[flagged]
- hedora 3y agoArguably, it’s a misfeature of Teslas. My BMW i3 has a hard charging cap of 90%. (The UI scales the charge percentage and displays 100% between 90 and 100%) It’ll regen charge up to “really” 100%, but that would require something like a 5,000-10,000 ft continuous elevation drop, where you just ride the regeneration brake the whole way down. Nissan took a different approach. The batteries on the old Leafs died really prematurely because they didn’t have decent battery management. They fixed it on later models. Anyway, this stuff is mostly a solved problem these days. It would be nice if device manufacturers were compelled to provide an 8 year, 80% capacity parts and labor warranty on all non-replaceable batteries (like the car manufacturers do in the US).
- kccqzy 3y agoIt's very different when you are dealing with a $1000 object versus a $40000 object, where the replacement of the battery could cost $300 and $20000 respectively.
- gnicholas 3y agoAre we talking about phones and cars here? What phone costs $300 for a new battery? I assumed Apple would be on the high end, and they charge a fraction of this ($100ish, IIRC).
- kccqzy 3y agoThat was only an example. My argument is only strengthened when you use the actual cost of battery replacement.
- artdigital 3y agoI have this feature enabled at all times, but my iPhone 15 Pro (with always-on display) usually can't make it through the day. Still wondering if limiting always to 80% will actually increase longevity of the battery
- velohifi 3y ago[dead]
- wredue 3y agoDeep cycles are also bad for batteries. Honestly, I’d suggest trying to use your phone less. A new 15 pro has a pretty ridiculous screen on time even at just 80%.
- kccqzy 3y agoIf GP is like me where I always run an app tracking my location (with my consent) in the background, even using the phone for 1 hour per day would drain the battery from 100% to 30%.
- Eisenstein 3y agoGo into the shortcuts app and create a shortcuts that turn off wifi when you leave areas where you use it and turn it back on when you return -- this will prevent the wifi radio from searching for APs constantly. Go into settings and check all your apps for background refresh -- there are probably a bunch that don't need to be constantly for new content when you aren't using them. Switch to Brave Browser instead of Safari -- the built in ad blocking will save CPU cycles on websites. With all of these set you can probably get another ~1hr or maybe ~2 if you have some egregious apps refreshing and a whole lot of APs you can't log into that keep coming in and out of range.
- hedora 3y agoOn my 13 mini, I just set a shortcut to turn on power save mode when power save mode is turned off. I also set a geofence around the cell dead spot at my house to enable airplane mode. The latter spams notifications due to an (anti-stalking?) “feature” of shortcuts that doesn’t let you disable geofence notifications. That bug can then be fixed by exploiting another bug by enabling screen time, the creating a custom app shortcut that produces a notification. Run the custom app a bunch and screen time will decide it is spam, and force-enable the “disable notifications” toggle for the shortcuts app. (Apparently this doesn’t work on some of the newer/higher end iPhones. My guess is they copy pasted the policy logic for each model, and forgot to backport a bugfix). The above greatly increased battery life and did so transparently. Now, all I need to do is buy a smart plug and have it toggle the power on a low-speed charger when the iPhone battery is above 80% or below 60%. After that, I’ll do the same for my watch and iPad. Couldn’t be simpler. /s
- voisin 3y ago> I also set a geofence around the cell dead spot at my house to enable airplane mode. How?
- jostmey 3y agoCould the decision to support the 80% charging limit for only iPhone 15 be related to changes in battery chemistry? Does the iPhone 15 use a different battery chemistry? I ask because I have noticed my iPhone 15 charges to 80% way faster than my other phones and devices
- Panzer04 3y agoUnlikely. Virtually all lithium batteries display similar characteristics with respect to charging. Charging faster is something that can be variable between chemistries, but typically batteries are fine with charging quite quickly in the first 80% regardless, and can be made to tolerate fast charging (though usually you sacrifice a little bit of lifespan or total capacity to increase that tolerance)
- purjolok 3y agoFor rooted Android phones, there's ACC: https://f-droid.org/en/packages/mattecarra.accapp/ https://f-droid.org/en/packages/mattecarra.accapp/
- Semaphor 3y agoThat is AccA though, the unofficial frontend. You still need the actual acc app: https://github.com/VR-25/acc/ https://github.com/VR-25/acc/
- ewoodrich 3y agoIt's also a setting supported natively on Samsung devices.
- imp0cat 3y agoI suspect it's mostly because of the exploding Note fiasco. But it's a great option to have.
- pipeline_peak 3y agoThis reminds me of when water bottle companies reduced plastic by 30%. Of course unlike Nestle and Coca Cola, Apple is too hip to be known for its environmental impact…
- soultrees 3y agoI have an 11 pro as my main workhorse. Multiple years old, constantly running the battery to 2 % then charging to 100 and it still lasts all day for me. I feel like the concern I see going on in this thread might be a bit misguided.
- stealer0517 3y ago[dead]
- seemaze 3y agoMy 11 pro was the same way. And then I got a 14 pro.. it has noticeably worse battery life, I suspect in part due to 5G which I have since disabled. I tend to keep it on the charging stand on my desk for video calls as it now has magsafe (or whatever it's called). It's constantly charging to 100% and I'd love to have a way to stop it from charging without having to remove it from the stand like a cave person.
- NikolaNovak 3y agoIf we are sharing anecdotes, my wife and I got iphone xrs same Xmas. She regularly fully discharged hers, whereas I charged mine throughout the day. My phone very very rarely goes below 40 or even 50 percent. After couple of years, her battery life was awful and mine was fine. Basically, I find individual stories vary, but statistics may show overall trends
- falsenapkin 3y agoGlancing at some comments here mentioning the overnight charging feature working for them, am I in the minority by charging randomly whenever it needs it? My charger isn't even in the bedroom. Curious how my random on/off habits compare to overnighters in long term battery health. I try to take it off around 80% so I was interested in this feature and confused when the update didn't include it. I don't like that it's in my "pros" column for upgrading when it could be available to everyone, would rather not reward them for that.
- zootboy 3y agoThe world of lithium-ion battery chemistry is quite complicated, but in my experience, the top contributors to battery wear-out are, in decreasing order of severity: - Charge cycles (including partial cycles, e.g. 100% -> 50% is half a charge cycle) - Depth of discharge (deeper discharge cycles are worse) - Extended periods in hot conditions (over 40 degrees Celsius) - Extended periods of being held at 100% state of charge In essence, your charging behavior dings the first two items: higher number of charge cycles, and deep discharge cycles. If your goal was battery longevity, keeping the phone plugged in as much of the time as possible would be the best strategy. Bonus points if your phone supports a "stop at 80%" mode, but still the winner even without this feature.
- publicmail 3y agoI think another huge killer of lithium batteries is charging them when below freezing. I bet most phones probably wouldn’t allow it though - or at least would limit it.
- zootboy 3y agoI left out things that a typical battery management system will prevent, like over/under charging, or operating outside safe temperature limits. But yes, charging a typical cell below 0 degrees Celsius will immediately and permanently damage it. Here's a ref with some details on why: https://www.bonnenbatteries.com/lithium-battery-low-temperature-use/ https://www.bonnenbatteries.com/lithium-battery-low-temperat... Li-ion chemistries that are tolerant of charging at low temperatures are a subject of active research.
- r2vcap 3y agoI am a user of Samsung Galaxy and Apple MacBook Pro M1 Max. Both models offer Battery Limit/Battery Protect features to protect the lithium-ion battery. I first realized that other iPhones, except for the iPhone 15, don't have such a feature. Maybe it's a good idea to include it?
- byyll 3y agoApple doesn't really care about their iPhone customers. They prefer milking them for more money by forcing them to buy a new model instead of adding a feature that would actually help the environment which they often lie they care about.
- justo-rivera 3y agoI can't imagine caring about this honestly. The way i feel it is like constantly caring if your white shoes are dirty, i only trust my shoes to help me walk. Technology should be as transparent as possible in my opinion and not bring us back to thinking about said technology, just what we can do with it. It's tiresome enough to worry about having a charged phone, i couldnt bring myself to look at battery percentage or even phone charger options just because i am calculating how long will my phone last in the long run.
- Reason077 3y agoThis is just an optional feature, nobody is forcing you to turn it on, or to care about it. Personally I rarely need a 100% charge: my iPhone 13 easily gets through a typical day with 40% remaining. But I do get annoyed when a phone is 2 or 3 years old and the battery is already worn out. Genuine iPhone batteries are expensive, and limiting charging to 80% will significantly extend their life. Worn out batteries don't just have limited capacity, they charge slower and create more heat while charging due to internal resistance. I'd much rather charge to 80% for my typical day, but have the option to 100% charge on those rare occasions when I know I might need it (long day travelling, etc).
- Scoundreller 3y agoWhile not ideal, maybe we could have more trickle chargers? My worry is that the battery actually gets used often but for short periods and that could effect long-term wear. Personally, I have a Shortcut to put my phone into "low power mode" once it hits 90% (why not?). Maybe a Shortcut could do the same and turn off power once it hits 80% on your overnight charging dock and then use a small amount of power while the screen is off.
- gnicholas 3y ago> Personally, I have a Shortcut to put my phone into "low power mode" once it hits 90% (why not?). Isn't low power mode for when your phone has very little battery left? I don't understand why one would put a phone in low power mode when it's charging and hits 90%.
- SirMaster 3y agoI just do this with a Shortcut in the Apple Shortcuts app and a smart plug. Create an automation when the battery hits 80%, switch off the smart plug.
- balls187 3y agoWhy not make 80% the new 100%?
- compiler-guy 3y agoBecause there is a trade off here between ease-of-use day-to-day and long term longevity.
- harry8 3y agoBattery is at least 20% too small then. The trade off with making it bigger is not for the user it's between engineering and marketing, which is dumb.
- anArbitraryOne 3y agoI'm pissed that stock Android doesn't have this unless you charge for 4 continuous days
- Reason077 3y agoI recently had a battery fail pretty spectacularly in a Huawei 5G router, which had spent most of its short (3 years) life sitting charged to 100%. Admittedly the replacement battery was cheap, but the failed battery was a messy hassle to change since it had swollen up so much it almost blew the housing of the router apart. And potentially dangerous if it had split open or caught on fire. If Huawei had a "limit charge" feature in this device, it would probably have avoided all that hassle!
- elhenrico 3y agoThere should be an option to use the charger directly without involving the battery.
- Reason077 3y agoI would like to see this feature in Macs, too. In my experience, the current "optimised battery charging" option doesn't work well unless you have a very regular charging routine.
- artdigital 3y agoOn an iPad, is it better to keep it plugged in at all time so it switches to AC power and doesn't touch the battery, though battery stays at 100%, or do some trickery with an automated socket to cut charging once it hits 80%, then re-enable power once it's at ~25?
- Cody_C 3y agoThese kinds of features being so limited annoys me. Like GoPro can only auto clear a video from your sd card that has been uploaded on the newest model. There is no way that is limited to those devices. But, it probably isn't profitable to even crack open the code for the older models so they don't even consider it. It makes it worse because I'm even paying a subscription for storage.
- stefandesu 3y agoIt's much worse in this particular case. They purposefully had to lock the feature behind a device flag to prevent older phones (that still support the newest OS) from using it. I'd expect that they could easily enable the feature for all phones that also support Optimize Battery Charging.
- unholiness 3y agoThe Chevy Volt has the perfect handling of this: A new car never charges past 90% or drains below 10% battery. It simply reports 100% when the actual battery isn't quite full and vice versa, extending the battery life significantly. As the battery life degrades over time, it will try to keep the same useful range, and shrink those boundaries until you are using the full battery life each charge. Perhaps this works less will for phones, but I'm not so sure. Personally I never have issues with battery on new phones. It's only as the battery life shrinks that you really need the full range.
- rrrrrrrrrrrryan 3y agoI've never understood why these companies don't just add a redline: make the battery chargeable to 110%. By default have it stop charging at the recommended 100%, but let the user decide if they need that to go beyond that and are willing to damage their battery health to do so.
- theshrike79 3y ago> let the user decide Most users don't know enough about battery chemistry. WAY too many people don't even understand how USB charging work, their brains are still stuck in the barrel jack charging ages where the charger pushed power and the device just took it (or blew up).
- charlie0 3y agoI wonder what's worse for the battery, constantly getting the battery down to 5% and charging it back it to 80%, or letting it go up to 100% and never letting it drop under say 20%.
