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

[tonypg]

The answer is neither are correct. Total screen on time is based on screen on time which is based on app activity time which are all flawed by their very nature.

I wish I would have seen this app sooner to safe you guys a lot of time.

Battery is a light weight system using shared resources to GUIDE the user to potential battery hogs. Its very generic and if nothing immediately sticks out at that time then it has nothing to offer you. You should not go diagnosing these numbers at precision levels because they will send you on a wild goose chase, they are not accurate in any sense of the meaning outside of a "quick overview". Again its a light weight system because precision tracking requires considerable resources thus measurable battery usage.

So here is mine manipulated for this thread....

Notice how my iPhones clock in the upper left is 11:11 then notice I have 1 hour of screen on time between 11pm-12am (same hour). Hour screen on time in 11 minutes....

This is because I can see seconds aren't tracked. Every app that is opened is "1m" at 1m 1s its "2m" so seconds are rounded up a minute PER APP. So merely by opening 60+ apps (1 app automatic adds 1 minute so 60+ app = 1 hour) you will give yourself 1h screen on for that hour, this will effect the total screen on for 24 hours.

Now that 60+ apps had no effect on battery so when using the app for diagnosing battery issues (looking for sudden drops in battery life) its not directing me there.

The app can be useful however we as enthusiast can easily over analyze it, those of us with battery issues can also see things that aren't there because we are trying so hard to see something.

I can type up a quick and dirty guide to using (or dismissing) the battery section if settings if anyone is interested.

I knew the battery page in the setting is for a simple overview than an actual analytic report but your explanation saves me time to drill deeper into the reasons. Thank you for that.

Unfortunately, my iPhone 13 Pro battery does not last long like others. I created a post to provide a full context: https://forums.macrumors.com/thread...-context.2315606/?post=30402094#post-30402094

Do you have any tricks that can exam the true battery-draining apps or processes? Some of us suspect the apple watch linkage may be the reason. I just unpair my apple watch and will monitor the battery tomorrow.

Has anyone done/seen a Chrome vs Safari battery test?

Its likely a combination of many things causing higher consumption in general judging by your linear battery graph.

I have a fairly large Apple ecosystem that isn't doing me any favors. Syncing with iCloud Messages, Photos, Files, etc with 2 macs and 1 iPad plus using HomeKit with security cameras, etc etc is convenient but comes at a small battery hit. However compared to do all that stuff manually outside of iCloud would use more battery via individual apps.

Apple Watch I'm sure comes at a battery expense but technically could save you battery. If you get 100 text messages everyday and read them on your watch, its likely better then opening the iPhone and using its screen to read it.

Console and Instruments on Mac can monitor activity to some extent but I don't have a good way to pull a report that is exclusive to processes that are using the most amount of energy. Instruments for example can be configured as such but only typically can monitor details with YOUR app not other devs apps.

I have a few devices signed out with no Apple ID. They get text and calls but not much else (can't download apps without an AppleID). The battery will last for DAYS. Its incredible but its nothing more than a feature phone at best.

Apple requires browsers to use Apples webkit framework so Safari will be better optimized for the iOS and the devices hardware thus better to the battery if comparing apples to apples.

However that doesn't mean you can't find an extension for Chrome (or another browser) that blocks ads better or doesn't load various things that you deem unnecessary. In that case a task no matter how well optimized won't be faster and less battery intensive than not doing that task at all...

Thanks, in theory this all makes sense. However, curious as to what the numbers show if anyone has actually tested.

Yesterday 1:20h SOT = 70%
Today 1:10h SOT = 85%

iPhone 5h off the Charger

 

[Davelfc]

I’ll put this in here.

I have been running my iPhone 13 pro now for 10 days. It still hasn’t worked out my schedule, it charges the battery to 100% straight away at night instead of optimising the charging.

I use a genuine MagSafe charger, with a genuine apple usb c charging block. I go to bed at almost the same time each night (with roughly 50% battery) and wake up roughly the same time each morning. I have never in those ten days touched my phone from putting it on the charger to taking it off in the morning.

I have a sleep schedule that silences phone and watch for most of the time I am asleep.

Weird as I have found that previously the battery optimisation has clicked in after three or four days.

And yes I do have battery optimisation turned on.

my launch day pro max is also charging straight to 100% at night and is not optimising the charging yet despite it being switched on

 

[coso]

battery optimisation never worked on my iPhone 8 either. Worked on my GF 6S

 

[The Game 161]

Certainly not had a day lower than 5 hours, 30 mins screen on time. Very happy overall and nice to know I will never need to worry about battery life.

 

[aohus]

13 pro. 21% remaining
iOS 15.0.1
Mostly indoors w/ wifi
Towards end of the night you can see usage go up, was in a room with lights turned off. This definitely elongated usage time since display is at very low brightness
Currently satisfied with battery life when not moving around much.
Phone could have easily reached 9 hr SOT if drained to 0%

 

[mackie8]

32% left

I’m impressed with the battery life of my pink 13..

Haven’t had a day lower than 8-10 hours lol.

Finishing most days with 40-50% left.

This thing is insane.

Reckon I can hit 13 hours.

 

[jsamuels]

For my 12 PM it took two weeks before battery optimization kicked in. As I recall, I received a notification when it did.

 

[xxBlack]

Restoring made no improvements. 65% and 2:35h SOT , 25 min SOT on LTE

 

[SaguaroSeven]

my launch day pro max is also charging straight to 100% at night and is not optimising the charging yet despite it being switched on

I don't know how long learning takes, but you get a notification that iPhone will be using optimized charging when it completes it's learning.

 

[Bodhitree]

In the first day I was getting App Store using 54% and a steep downwards curve from 70% … the phone does appear to do some quite intensive things at first.

Now in the second day it looks like this:

Question Im new to the whole iphone world, this is my first iphone..yesterday evening when I turned off the iphone(I went into settings, and shut down) it was at 95 percent charged..this morning when I turned it on it was at 85 percent..is that normal for an iphone to drain a little even when its off..I have twitter, facebook, text notifications but the phone itself was off so I figure when the phone is off the battery life should remain what it is when I turned it off..or is it normal to drain a little even when "off" Thanks appreciate it

i think your battery is still optimizing. i would also disable 'find my' even when your phone is off, its a new feature that was implemented in ios 15 for find my to run even when the phone is off. go to settings --> your name --> find my --> find my iphone --> disable find my network (keep find my iphone tho)

Thank you so much appreciate it..so the only thing I should disable is "Find My network" what exactly does disabling that do?
I assume by going into settings and shutting down iphone(The bar comes across the top of the screen) is how you turn off the iphone(My sister told me to hold the power the volume button) not sure which is better to do
Do you think by disabling find my network it will stop with any kind of slight battery drain?(Funny thing is now when I go to my iphone its still at 85 percent charged..I guess Im just picky since with my old phone the battery was always draining like crazy so I became overly obsessed with battery life

 

[Quarric]

13 mini
15.1
Approaching 5hr screen time.
last charged to 100% 3-4am. 50% remaining around 14:30, charged for 8 minutes to 55%.
30% remaining now.
Only had it up and running for a couple days.
Mix of browsing, audible, online banking, music, YouTube, camera, mail, WhatsApp and a couple of background things Fitbit and a nav app.

i would just keep using your phone as is since you just got it. give it a few days and it will normalize. you can always use this handy guide if you want to eke out the most of your battery life:

Thanks so much appreciate it..I realize I have been turning the phone "Off" the wrong way which might explain the battery drain. Instead of powering it off by pressing the power and the volume button ive been going into settings and "Shutting down the iphone" maybe thats why it drains a little bit so tonight will be shutting it off the right way to see if that makes any difference
Also, another question, I have the 2018 ipad pro, and it came with a charger, it looks exactly like the 20W charger apple is selling for 19.99..I was chatting with apple and the lady said I should NOT use the charger I have now, that it wont charge as fast as the 19.99 one that that one is newer and works with the iphones..is that true..I did notice when I first charged up the iphone(When I received it it was around 70 percent charged, took over an hour and a half to bring it to 100 percent charged) should I use the charger I have now(And use the cable the phone came with) or buy the charger from apple

Edit : I just looked at the charger I have now and it does NOT say the wattage..I think on the iphone charger it says 20W so perhaps I do need to buy it
