Other When will iPhones start lasting at least a day or 2 days with heavy usage ?

As performance of the phones increase, the apps that support these devices become more demanding. Apple hasn't shown any desire to make a phone that lasts multiple days. Apple targets an average all day usage. If they really cared they would have included larger batteries ages ago.

whats heavy usage? there isn't a phone out there thats gonna allow you to play heavy games for 5 hours without killing the battery.

but with the a12, apple easily could've put a huge battery in it (all other manufacturers have been able to) and just absolutely wipe the floor with all the other phones in terms of battery time. they just choose not to b/c they just want to do enough to keep up with the competition and maximize their profit margin.

Not really gaming but using the phone constantly.

I know mobile gaming kills a phone's battery life quickly.

again what do you consider heavy usage?

i feel all the flagship phones from everybody can last all day. no way any of them would last 2 days with heavy usage though.

I don't know.

I guess 1 hour of mobile gaming, facebook, email, light photo editing, surfing the internet, and calling/texting

The A12 with 7nm CPU, running at a slightly lower speed in order to keep the GeekBench4 score at least the same as the iPhone X/8, could likely have pushed the Xs battery performance past most Android phones, and much further than the 2017 iPhone X. Maybe that could allow us to have enough power to surf the web and post to facebook or watch movies for longer periods of time.

On the other hand, maybe the low-power cores are already handling this for us. One way to be sure would be to set the iPhone into low-power mode and then use it constantly to surf the web and read email, and then see if it lasts longer than in full-speed mode after we have already turned off background app refresh and push email.

I still feel like we should have more options to extend battery life than just low-power mode, such as giving us a "mid-power" mode that lets us throttle the CPU but without turning off background app refresh and email fetching. However, with all of the low power cores, maybe it's already doing that?

I really need to test my Xs max and see how it compares to what my X has been like for the past year. i tend to drop my phones onto a wireless charger when I'm sitting in the family room, or plug into the car stereo when I go for a drive, and that keeps them topped off. In 10 days I haven't gone full unplugged all day with the Xs max yet.

But on my iPhone X, with very little use (not in low power mode and with background app updates turned on for about 30% of my apps), I found that I can let it sit for up to 48 hours before the battery is dead. Using the iPhone X for mostly calls, texts, alerts, and emails, and my iPad for everything else, my X would have 20-40% battery left after being unplugged for 16 hours.

Reading a Kindle eBook with dark screen and white text for 4 hours during one of those moderate use days would drop the battery another 20%, so that I'd still have 5-20% battery left after a 16 hour day. Using facebook and youtube for 1-2 hours on top of that would ensure the battery was depleted completely within 15-16 hours. That's still about 2x as long as if I had just been watching movies or playing games.

Will it ever happen ?
yes. when we see a breakthrough in battery technology. when? idk. but i have seen reports of breakthrough in labs that can probably double the storage capacity.

Newer age battery tech I still don’t think is ready for the smart phone market yet. Lithium ion, even though it’s been around for quite some time, has greatly improved with efficiency and longevity, even with smart phones have become increasingly strong with power draw due to the camera and processor tech. I suspect battery tech to change the duration of how long a phone lasts is easily 3/5 years out. Lithium ion is very much capable for the future as it stands.

Probably will not happen for a bit. There are only two ways to achieve this:

1. Bigger or more effecient battery in the same size. Apple, we know will not make the phone bigger. This means that components will have to become smaller to increase battery size or their will have to be a breakthrough in battery design. The first is what they've been doing anyway and is unlikely to yield massive improvements.
2. Components have to use less power, mainly the screen and the CPU. Oled to Micro Oled will help and is on the horizon and they just shrunk the die to 7nm.

Make the phone thicker is the only way but too many factors. Hell even the iPhone XS max which i use heavily feels like same battery life as my previous iphone 8 plus... like honestly the bump in resolution (26xx by 12xx) over 1920x1080 just negates the increase in battery size so technically they’re the same...

HOWEVER, the upcoming iphone XR i believe will have the best battery life of the bunch. Larger battery, smaller than 1080p screen means less pixels eating juice. On a surface level if people want best battery life, the XR is it... plus they have the 128gb option... wished the XS max had 128gb option but nope anyways i should be fool proof for another 3-4 years. I dont expect to upgrade every two years now its redundant for a minor gain.

Apple sizes it's batteries for the average user. They expect you to charge it each night.

The average user should have enough power to last all day with some to spare.

A "heavy user" depending on how heavy may not last a full day much less two days.

Apple would have to increase the thickness of the phone a good bit to satisfy only a few users that "live" on their phones. This is not going to happen as Apple is into "thin"!

I figure one of these days phones will get their power from another layer in screen that is solar power. Or they’re powered by “air” or something better for environment than current battery lol so whenever they can “self charge” is my guess.

Have my doubts we will see this anytime soon.

I know you will claim otherwise but do not care to be around a device that can charge from distances.:confused:

Just a personal preference thing.
You may not have a choice. Every wifi hot spot will be putting out a wireless charging band. Whether you use it to charge your phone or not, you will be walking through it. I'm guessing you don't want 5G either.

I think the statement in bold has been proven wrong... the iPhone 7 was the last time we heard that “this is the thinnest iPhone EVERRRR!”

Apple will only increase the size of the phone when they feel the benefit is worth it (i.e. adding wireless charging, OLED screen, etc.)

As other people have stated, they are out to maximize profit and provide a good phone experience (in regards to battery life) for the “average” consumer.. that means making the battery just big enough to last a day and using the rest of the space for components they can use to convince people to upgrade or make it smaller in hopes that a “thinner” device will be appealing to the skinny jeans crowd.

I think apples thoughts on this subject are .. people tend to charge their phone every night anyway, so in theory they only need a battery that will last a day. (With some % to spare)

To be honest, i think I’ve had one account where I wished my battery had lasted longer than a full day. I put my phone on charge every night, regardless of charge left.

Or if I’m going on a night out and I’m on say.. 45%, I’ll top my phone up for an hour or so before heading out.

Edit. For instance on a Friday I’ll leave home for work at 6:30am with 100% in my phone. By the time I end up going to bed that evening I’m usually left with 20-30% left in the phone.
