What If You Used iOS 9's Low Power Mode All the Time?

My Nexus 5 is so slow and clunky in Battery Saver mode that I seriously wonder if it actually helps. Taking a minute to do something in Battery Saver mode isn't necessarily more efficient than spending 5 seconds in normal mode.

He meant the "extreme" low battery mode some vendors like HTC, Samsung[1] and Sony implemented, which soft reboots your phone into a power save mode where all you can do is make calls and send texts.

it's definitely an issue if you have background refreshing enabled on a lot of apps.

or any of those motion tracking / gps apps

Battery life has got worse and worse though. For me it's less than a day if I'm using my phone heavily (which I often am e.g. on public transport I'll watch videos or browse the web). If I'm going out after work then it's work -> bus or train -> theatre -> bus or train home, if I haven't charged my phone since that morning then it's dead by then. So I've taken to leaving a charger at work but that's got its own awkwardness (unapproved device, other people "borrowing" it). I don't really want to carry a charger around in my pocket (if that's the alternative, I'd rather have a heavier phone with more battery life).

Pretty much. I have a 5S and it makes it through a full day of moderate use or two days of light use. The only time battery life is a problem is traveling on the road, where it seems to burn through battery roaming (I assume). But, if I'm in a car, I can probably charge. In the woods, I have the same problem, but using airplane-mode solves it - if I'm in the woods, I don't want to answer email or phone calls anyway.

I don't own a car and walk a lot. I also have a very limited amount of bag space- I carry a small bag that can't hold much more than my computer, phone, and wallet. Being able to have my phone run all day long without hassling with carrying a spare battery is nice.

Right now my 5 does okay; it usually only needs a recharge on a day when I spend a lot of time with terrible reception. But it'd be nice to not have to hassle.

And... well, I really love not having to carry a power brick for my Air any more unless I'm going on a multi-day trip. One less battery pack and cable in my bag would be a nice thing. Less is more.

When I get around to switching to iOS9 (I like my jailbreak), I'll probably use low power mode a lot on days when I know I'll be draining the battery.

If I don't use my phone (5S) it will make it three days. But if I am sitting around surfing the web, using Snapchat and Facebook, I can burn the battery up in six or seven hours. I get up at 7am and I've had days where I was at 20% by 1pm if I used it enough.

Then you have the mystery usage when the phone gets hot to the touch just sitting in my pocket and I can almost watch the percentage drop.

I completely agree. I'm either at work/home with my phone plugged in, or I'm traveling, and if I'm traveling I'm going to carry an external USB battery anyway because no practical smartphone is going to last for, say, a 7 day backpacking trip.

It seems like the only people who would be complaining are those whose required battery life is in the narrow window greater than current phone battery lives and less than the point where it's more practical to carry an external battery. I wouldn't think that would be all that common, but I might just not be thinking of people's use cases. Two obvious examples I can think of would be frequent business travelers (those with trips in the narrow window I described) and people whose day jobs are not near plugs or require a lot of moving around with the phone (i.e. not desk jobs).

It depends on where you are - cellular quality is a huge factor if you don't have wifi or string 4G – and how much you use the phone. One really big factor is the way judiciously pruning your installed / background app list: take any non-savvy user's phone and you'll probably see significant usage by things they rarely use.

People have simply been trained to plug in their phones frequently, and especially at night. They've further been trained to replace their phones after a couple of years, before the battery fully wears out. And to me it seems the typical smartphone user is compulsive about checking things. For everyone else whose behavior hasn't been formed around the ideal needs of a smartphone, a longer battery life would be nice, like the 4 weeks my feature phone gets.

My Galaxy S4 decided to melt its usb port in a car charger about a year ago. Since then, I've bought a couple of extra batteries (much cheaper than expected) and a couple of external chargers. Whenever I get around to upgrading and get a phone with a working charge port, I expect I'll continue my current practice. I'd much rather throw a spare battery that's little bigger than a credit card in my pocket than faff around with usb cabling or hope I make it through the day. Also the external chargers top a battery off much more quickly than charging through the USB ever did.

... I've got a bigger Huawei phone with a 4000mAh battery. My wife has a smaller Blu with a 5000mAh battery.

Not having to charge feels revolutionary. I only need to think about it once every two days. I can go out and never have to worry. Fall asleep whenever and never worry there phone won't be available when I wake up. It's quite a nice feeling.

If Apple had the decency to ship phones with a 24h+ battery, everyone would take it for such an obvious minimum standard there'd be no discussion. But since Apple's expensive phones don't do this, people have developed this Stockholm Syndrome where they feel fine that their high end device constantly runs down. Gift I've been thanked the most for? External 10,000mAh battery for an iPhone user.

You know, it's because of people like you (and a vast mass of people who don't care enough) that we can't have long-working phones. In short, a phone with greater battery life is a boon when you:

* travel a lot. It doesn't have to be often - but when you leave your room early in the morning for a long day in a new town, and use it a lot, it really gives you peace of mind to know that you will be able to make that last important call in the evening.

* forget to plug it in. Seriously: do I really really have to plug this gadget in evry single evening? what if I forget or don't have the means to, every once in a while? It's a flagship device we're talking about; isn't it supposed to make my life easier?

* want your phone to have extra margin of reliability just in case - either to prolong its life when the battery deteriorates over time, or use it in cold weather - I am not sure if it's permanent damage, but battery holds less charge in the cold.

The iPhone is not the worst offender - it's probably slightly above average as far as smartphone battery life goes, but, to me, saying that battery life is not an issue sounds like a blasphemy: we (the consumers) have just squeezed barely adequate battery life from the manufacturers and voicing the opinion that it's enough feels like inviting back the compromises that they (the manufacturers) are far too happy to use.

The battery pack sure solves some woes, but it's not by coincidence we call it a mobile phone: it is supposed to be self-sufficient. Do you like to carry around a second box on your body at all times, just to be able to use a smartphone reliably? I don't. Battery pack should be a bonus that's nice to have, not a requirement to last through the day.

It's still a massive issue for me. My Z3C is the first smartphone I've ever owned that pretty much always makes it through a day, even days with heavy usage and I'm stuck trying to make a call at 2AM.

Most smartphones would crap out anywhere from noon to 6-7pm - and my usage isn't that heavy on typical days, maybe 1-2 hours of screen on tops and an hour or two of bluetooth audio.

Sure, I'm often around sources of power, but that means I now have to carry cables, chargers, and battery packs around as part of my daily routine or when going hiking and biking. No thanks. With my Z3C, I no longer have to carry all that junk around, and I know I'll still be able to use it in an emergency even if I get stranded somewhere.

And even if I carry all that crap around, just because I'm usually around sources of power doesn't mean I'm always around sources of power.

It depends... in my family life (gf, live together, plan things like dinner so I tend to know when I'm home in the evening) it's no issue. But in my student life, it'd often suck. Come home from college around 5 pm and get a text from a friend who wants to eat out somewhere, alright... leave the restaurant around 7, go to a bar for some drinks around 10... if I go home at this point, no problem, but I'd already be in battery saving mode by now. If we then decide to meet some other friends for drinks and then go clubbing, around 12 my phone is dead and checking to see which bus or taxi can take me home around 4 AM is a no-no. Crashing at someone else's place for the night? Let's hope he has the same phone (trivial for android nowadays, even iPhone users tend to have micro usb laying around).

Anyway in some ways it's very much an edge case (how many people are students who find themselves in the above situation often?). Still battery issues are still something I run into and the idea of carrying a charger anywhere I go didn't fit my lifestyle for a long time. (generally went places without a bag, and even if I did have a bag I'd go to different places I didn't own in some way or stayed for long (like an office space where I could keep a spare charger and plug in for most of the day). Today it's not an issue, I spend most of my day at the office or at home, have chargers in both places and tend not to be away from either for more than 10 hours. But I still feel a bit restricted, visiting my parents over the weekend used to be jumping on the bike and going there whenever I felt like it and deciding to eat and perhaps even sleep over would be a spontaneous decision once I got there. Now I have to actually plan ahead for that or be stuck without battery on a phone I rely on nowadays, it may seem trivial but I'd still love to pay a substantial amount for a better battery, and would very much welcome modern phones to be 10-30% thicker/heavier, filled with battery. Take the first iPhone, that was 12mm, today we're at about 7mm. I totally wouldn't mind to go to 9mm and get 28% more volume which'd probably be at least 40% more battery. Hell wouldn't mind the iPhone 6 performance in the 6S, either but that's just me. Combined it inches closer to the 2-day usecase, or day, night and early morning usecase that I feel should become a minimum standard in 2016, that has the priority over dropping below 7mm phones for me. The iPhone 6 for example was 6.9mm, the 6S are now 7.1mm, nobody in the world cared their phone got thicker and is 14g heavier than the 6, which was 17g heavier than the 5S, again nobody shed a tear over that, < 8mm is good enough, < 200g is good enough, for me anyway.

Traveling in Japan over the summer, I bought a powerbank. It was useful because I was moving a lot, taking a lot of pictures with my phone, using it a lot for other stuff without charging it. Plus I always had a 4G modem with me.

However, more than 25% of the Japanese I met were using Powerbanks too. Look around you at a smoking area, in the subway,... and those numbers may confirm themselves.

You might read this article as saying "here is a new innovation by Apple that you should be amazed by," but I think a much more natural reading is "here is a hack to get a better experience from your (Apple) product if you don't mind trading battery life for CPU/brightness."

The author does mention this Android feature in passing, claiming that "it’s not like the extreme low power modes found on Android phones that basically turn everything off and turn your $600+ phone into a dumb phone."

Disclaimer: I use an Android phone. I don't use low power mode, so I don't know if his "dumb phone" claim is correct.

My phone has a low power mode (Sony Z3) which works the way he's describing the iPhone feature. It also has a super low power mode that turns it into a dumb phone so perhaps that's where he got the misguided notion that Android turns into a dumb phone in low power mode.

> new permanent mode

Do you actually turn it on manually every time?

What does the low power mode actually do?

This happened to my 4S as the battery aged, but that was during the iOS 8 era. One thing which made a huge difference was disabling background refresh. If you're not willing to go that far, use the battery menu to disable all but the most important apps. Otherwise, they tend to go things like keep the radio running, which is even worse with the 4S's 3G radio and correspondingly longer times to connect, and especially bad in areas of low signal (e.g. the building I work in).

FYI, the battery replacement on the 4s is really, really easy (back plate just slides off, versus removing the screen via suction on the later models). It'll cost you $15-25, depending on where you buy. Guide: https://www.ifixit.com/Guide/iPhone+4S+Battery+Replacement/7...

I'm happy they are kept separate, they (often) serve totally different functions. I was genuinely surprised not to see it in the control center though, seems like that would be helpful.

It shouldn't be needed most of the time, so it'd be a waste of space, but really it just emphasizes the need to have user control over the control center. I'd love to swap out some of the icons there for things I use more often.
