iPhone 13 iPhone 13 - battery life thread [MEGA THREAD]

Calibration is not working for me. After doing all the steps I activate the automatic brightness and it goes to 0%

You do the calibration after you turn it on in a pitch black room. Initially it will go to 0%, you adjust it after it goes to 0%. I set mine to 5% after it went to 0% in a pitch black room. After you set it in the pitch black room, you are done with the calibration. Don’t change the brightness after that. You are done with the calibration.

Before the latest update I was getting insane battery life now it’s just impressive, wonder what they changed ?

I worked it out - it’s that blooming iPhoto background processing stuff … again…

How much battery life were you getting before 15.0.1 and now on
15.0.1?

 

[George Dawes]

100% after 2 hours usage now it’s down to c 85%. maybe it’s calibrating the battery ?

still piddles all over my 8 plus 😆

that would go from 100 to 56 next day , doing nothing….

Do you guys have raise to wake on?

I have that feature turned off. Don't need it when I have an Apple Watch.

Ok I’m a bit baffled. can anyone explain how if I’m not actively using the torch, it’s saying it’s been used for 2h 7m over the last 24h period? I noticed something was draining the battery a bit more over the last 2/3 days and blamed the dark mode extension I’m running on safari, but I think this might actually be the culprit. How on earth do I stop it?

Try turning it on and then off. If that does not resolve it, a normal shutdown is the only other way to kill it off. After you restart, keep an eye on it if it still happens.

I have it on.

* 13 Pro on iOS 15.0.1 w/ 47% remaining
* Light usage today. No way I did actual 5hr 47 min screen on time though. iOS always inflates screen on time I feel.
* Apple watch is not currently paired.
* indoor wifi most of the time
* I noticed disabling cellular data doesnt really do much in terms of battery conservation.
* Phone drained about 3% overnight which is quite good.
* Lets try sticking to battery reports instead of turning this into a messaging service shall we? Thread is getting cluttered.

Well, I’m ok with my minis battery life. 6 hours SOT from 90 down to 10%. A few basic setting tweets with no Low power battery mode . I’m not saying I can squeeze out 7 but if 6 is the norm for the next year ( upgrade program ) then it’ll be a major win in my book.

edit. The portable Apple battery gives about 70 % additional juice when needed. ( still testing ) . I’d take that 10 hours optional SOT when need rather than caring around the brick Apple calls the Max. I’m not a gamer nor photographer so I don’t see the extra features as a need but to each his /her / whatever own.

Can we please stop charging our phones 3-4 times throughout the day and then posting our battery life. 🤔🤦‍♂️😂

I chuckled. Yeah, that def skews This thread

I disabled background refresh, 5G auto to 4G only - I don't see any changes. Battery was drain the same like on first day. I'm still waiting for any improvements.

 

[Taz Mangus]

Update: 18 hrs 30 mins on low power mode. About 4 hrs on-screen time. 41 mins of that was using Apple Maps (not CarPlay) with 5G. Right now I have used 23% of the battery.

EDIT: The estimate for on-screen time would be 17 hrs 23 mins using 100% battery.

Your right there is no way you did 5 hrs 47. Your on-screen time was about 5 hrs 59 mins if my calculation is correct adding up all the individual bars.

You have to post your battery usage graph in order for others to understand what you are stating. Post the graph with Activity instead of Show Percentage.

Try running with Dark Mode on all the time. That will save battery life because with OLED black is the absence of power. In other words, a black pixel means that that pixel is not requiring any battery to turn off.

heh what I'm saying is I actually did less than 5 hours 47 min, not more. throughout my usage felt like I maybe did about 4 hours or less

I use dark mode everyday

It looks like you had 3 hrs 35 mins on-screen time, used 51% battery. This is better then your last battery usage you posted. Still not great for a 13 Pro phone. You did have a lot more off-screen time vs last time, I have not calculated it but it looks to be that case. Are you using a ad broker for Safari? If you are not, you might want to look into using one. That will save battery life.

I posted this in the wrong thread earlier and should have been posted here.

Another update on my low power mode battery life extreme hyper milage test. I have done a calculation on the estimated on-screen time. Right now I have 5 hrs 32 mins screen on-time, 30% battery used. This would make the estimate of screen on-time for 100% battery to be 18 hrs 26 mins. That is insane bonkers battery life.

I can see why no reviewer would like to do a battery test of the 13 Pro Max in low power mode. I am going to wait to update to 15.0.2 until after I finish my battery test.

@Demaker I made a big mistake. When computing battery life usage, I did not take into account the off-screen time. I guess I really did not understand what that was, I had to look up what it really meant. It just means apps running while the screen is turned off. I just did a recalculation and your total battery usage was 5 hrs 10 mins (on-screen + off-screen), used 51% battery. Your estimated battery life usage for 100% battery would be just over 10 hrs. That is really great battery life for a 13 Pro phone. Hope that brightens your day a bit with that good news.

Do you think browsing Reddit with Apollo in dark mode at low brightness in 4G using 1% every 5-7 minutes is ok? Seems a bit much to me. 13P

If you continued doing that same thing until your battery reaches 0%, you would only get about 8 hrs 20 mins. And that is 1% every 5 minutes.

 

[Taz Mangus]

When we calculate battery life usage, need to make sure and include screen-off time because the battery is still being used, its just that the screen is turned off. I don't know why I had such a hard time understanding screen-off time. Its in the wording very clearly "screen-off", meaning the screen is off. 😂 😆. Sometimes, I over think this too much.

Which seems fine but also not super fine due to low brightness and dark mode. During the day it's probably 1% every 3 minutes. Will check but feels it drains very fast. But probably 4G is the really taxing variable, much more taxing than playing 3d games for example

One option would be to turn on low power mode. In low power mode, the 2 performance cores are shut down and only the 4 efficiency cores are used at 1.37 GHz/core. In low power mode the A15 only uses 3 watts of power. Even in low power mode, the A15 still can run a video game at a constant 60fps. There is s video that goes over this. I was shocked at how powerful Apple has made its efficiency cores. Low power mode does not mean no horse power.
