How's your battery life looking so far?

[NewdestinyX]

This is completely unnecessary; in fact depleting your battery until the device dies isn't good for it. We would do well to stop perpetuating these antiquated ideas about battery management that haven't been relevant in over a decade or more.

Zombie, you need to get yourself educated. We indeed no longer need to "condition" our rechargeable batteries as we did 10 years ago before the Lithium Ion technology came out. But even in Apple's own tech articles you can read that the battery power indicator software needs calibration at least once a month to give proper read out. It just so happens that the process is the same as the old "battery conditioning" we needed to do 10 years ago. I assure you - this has been proven again and again. You need to get caught up, sir.

And you're right that you don't want to do it often. Charging from 5% and down is harder on the battery. But once a month necessary for battery meter calibration.

Cite one Apple-written tech article that suggests calibrating an Apple device in the manner that you've proposed.

Last time I looked I was at 27.5 hours of standby with 9 hours of usage and it was at about 15 percent. The plus has blown me away in battery life.

That's true.. there is no need to do the full discharge/charge thing constantly, that was advised for older style batteries about a decade ago, to improve lifespan. In general the advice for devices these days is to keep them topped up with charge as much as you want, and not to wait for them to go flat.

However, I think NewdestinyX was correct about calibrating your battery meter, if it seems off. I'm sure I have read those instructions before somewhere. If your battery % is either never going to 100, or your device is switching off at 4% or above, then it can be worth a one-off calibration, in the manner described. It's not required regularly, but is an option if you're unhappy with what your battery meter is showing.

But otherwise, absolutely fine and correct to leave your device charging when it's on your desk, or whatever. Keep it topped up!

You can do your own homework, Pete. I did mine a long time ago and only share info here that is well backed by experience and a paper trail.

Don't tell me you've never seen your battery only reach 99% after all night on charger or sit on 1% forever? That's a calibration problem.

 

[NewdestinyX]

Here's one good article that cited several other Apple statements on the topic - though his first link to Apple doesn't specifically refer to the calibration process needed.

Read here to understand why the calibration process for modern LiOn batteries is still necessary periodically.

You're the one who brought up Apple technical articles that advise this be done on a monthly basis. The Apple battery maintenance page says nothing about calibrating the battery or the meter:

I will fully accept that I may be wrong, but I believe that you're offering outdated suggestions and am asking you to back up your assertions.

That's not an Apple tech article, and the Apple page that it links to (and several subsequent Apple battery pages) say nothing about calibrating the battery or SoC.

This calibration thing is gone from apples site. Its still on the UK one for some reason. I agree with you though. I just think apple didnt want to stress or confuse people and most may not even show %

 

[WilliamG]

No need to argue about it. No, I haven't run down my battery to zero. To be honest, I've not actually done that with any iPhone I've owned and never had an issue. But to appease the battery gods I'll make it happen to see if it makes a difference.

*edit*
Let me rephrase. I have done it in the past, and I can't say I've ever seen it make a difference in actual battery time/life. I have seen it make a difference in displayed battery %, though. Either way, I'll still do it because right now - not happy with that one aspect of the phone.

Yes apple did in fact ditch the statement. Still up on uk site though. I agree w calibration but think apple got too many questions. And most ppl dont even use %. But yes most ppl here on these boards do

 

[The Game 161]

Whats the average time you guys get on standby when asleep? i've been losing on average 7-8% over an 8 hour period.

Read again. It actually gives the steps in the article I cited. Apple is not a battery manufacturer so it's not surprising they don't undertake it more formally. In the past I've read the monthly suggestion - they must have changed their article more recently. As recently as 2 years ago with 5S the recommendation was still at Apple. But the current battery article does not.

Still plenty of evidence out there that the "remaining power left" sensor in modern LiOn batteries needs periodic recalibration. Keep reading. I assure you this makes a big difference. In 100% of the cases where people have complained questionable battery life out of their new phones. The next run after a battery recalibration gets them way better results.

Can you post the link to the UK version of the article from Apple?

I typically lose 3-4% over the 8 hour period when I sleep.

 

[sunking101]

My phone is at 100% when I awake because I leave it in airplane mode. Sometimes my 6+ used to be at 99%.

 

[imlynxy]

I typically lose 3-4% over the 8 hour period when I sleep.

Just checked mine 3 percent overnight in regular mode

 

[NewdestinyX]

Now here's a battery question I'm not as confident about. Is there any reason to worry about keeping your phone on the charger for hours and hours while you sleep? The app Battery Doctor on its readout - after all trickle charging is done after 100% - gives a message - "Fully charged - Please remove from charger to prevent overcharging"..

Most of us charge all night while sleeping. Is that bad?

Nah

most leave it hours and hours on charge it won't hurt the battery...most people charge their phones every night anyway

No, it's fine. Most batteries have circutry that will actually stop them from charging and allow them to discharge for a time before they resume charging again, so they can't be "overcharged". There used to be a problem with cheap batteries from China that you could buy on eBay for Android phones that allowed user-replaceable batteries not having this circutry and then it could be a big problem, but Apple's batteries most definitely are safe to leave plugged in. IIRC, it used to be recommended that you allow the battery to discharge to around 50% like once a month, but I don't know if this is still the case as we've seen that Apple has updated its battery maintenance pages.

 

[DPtheKid]

Tumblr is a battery-sapping app and approx 10% drain per hour is normal behaviour on the 6S+.
There are certain settings you can toggle to maximise battery life, have a play.

One last question, do you have background refresh off?

Yup!

Here's a page from Apple UK that no longer exists, but can be seen on archive.org

So this is at 1% before it died. Pretty awesome battery life. View attachment 588558View attachment 588559

How are you getting 15 hours playing games do you have any special settings? Do u use iCloud music please let me know. That's the type of battery I'm looking for

Thanks for info.. And yeah. I was very surprised to see Apple updating its battery maintenance pages. Clearly the guy in the blogspot article had a link to that page when he was writing his points about the necessity for battery calibration. Now when you click on that link it goes to the new updated page. I'm eager to see the UK page that was mentioned a few posts back showing the original recommendations from Apple for battery calibration. I knew it is still necessary. Apple wearing that it would be confusing to people shouldn't have really been a reason to change the recommendation. Now it looks like they don't believe it's necessary when it still is. I've noticed huge differences when I do this practice in my battery life. And the moment I think my battery is getting less effective I do the calibration and Bam I get the full battery specs back after I do the calibration again. So I know it's helpful. Necessary? I wouldn't go that far… but I will continue to do it and recommend it to people who feel the batteries are doing well.

But I certainly don't want to confuse people into thinking that I believe in the old nickel cadmium battery "conditioning" routine that is, as you said, Pete, no longer necessary for many years now.

Thanks! I knew it had been a long-standing recommendation from Apple. I wish they hadn't taken it down just to avoid confusion. It is still necessary on today's modern LiOn batteries and can make such a difference.
