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

Sorry if this is basic, but what did you look at in CB to see the idle battery expenditure? Just logging history for the battery? I wasnt aware you could use CB in real-time. Thx.

Where I marked it. For example right now with the phone idle. It’s expending .02 watts. Practically nothing. It is a real time number and changes. You can also see charging rate. Very useful if you want to test different chargers.

Used 80% now. 3 hours and 10 minutes of screen on time. It’s not terrible, but it doesn’t seem great either.

What do you think?

I think you’re right, it’s not so good (mine do better). The only way is to reset or contact Apple.

As you can see, during night my phone discharge constantly and I want to know if yours do the same. If not what should I check? I have low signal but I have wifi on and I never close apps in background.

It looks like you got about 5 hrs 3 mins, 80% battery used. Estimate to 100% battery usage, 6 hrs 18 mins. Not great battery life, more on par with what the 13 Mini would get. Is this what you are seeing for battery life consistently? If it is then maybe you want to try a couple of different things that might help;

• Reset All Settings. This won't erase any data on your phone. It will just reset all the settings back to factory. I would try the phone for a few days after doing this to see if it helps.
• Connect your phone to a Mac computer, backup the phone to the computer, do a DFU, restore while in DFU and restore from backup stored on the computer.

Thank you for your reply. I'm getting this kind of battery life pretty consistently. I followed your advice and I have reset all settings. Will try it out for a couple days and see if that helps. Thanks again!

I think it’s normal as you also have some background activity. My 13 Pro is similar and I also put in in airplane mode. 2/3% loss anyway

I’ll try to put in airplane mode, then I’ll tell if something changes.

Woa. I am confused. When I plug in I get "Discharging with..." whatever value was last shown as "Charging with..." Then after a moment it shows "Charging with..." and gradually goes up to 5W or so.

- How do you get "discharging" without the iPhone charging from Mac?
- How can you test a charger? I'm missing something here...

Ok, after plugging in, unplugging, plugging again, I briefly saw "Discharging with 0.42 Watts"... is that it?

Edit: Duh. Wifi.... With cellular ON discharges about .13-.23 Watts. Will Cell Off about 0.03-0.04. Very cool.
Maybe I need a shortcut to turn off Cell when I get home, and turn on again when I leave.

Incidentally, for anyone continuing to have battery drain: Battery Insights suggested today that High Display Brightness was consuming lots of power. I checked my Auto-brightness setting in Accessibility, and it was on. I toggled OFF/ON and the display dimmed slightly. Maybe it was stuck?

Attached the screenshot of the battery usage on day one with my iPhone. I was left with 73% before plugging in around 10pm. I guess this is pretty solid?

Today I started with 80% and lasted until 5:30 pm to 20% and I had a pretty bad cellular coverage that I think influence a lot. Not only on cellular data but also wifi.

I am trying to run down my battery to shutdown. I have been trying to do as fast as possible. I have been running videos continuously. The damn thing won't die 😂 😂 😂 I am even watching a video and surfing the web at the same time. The picture-in-picture feature is great. Everything seem to be so fluid on my 13 Pro Max. Very amazing how fluid everything is and does not seem to affect multi-tasking.

What a wonderful problem to have. The reason I am trying to run down my battery to shutdown, I want to then charge to 100%. I want to see if this might reset the battery calibration. It was suggested by another poster. So I thought I would try it.

Man the bonkers insane battery life is very consistent. I have never experienced a phone quite like the 13 Pro Max. The other thing I was really impressed with, my 13 Pro Max stays completely cool to the touch through all this.

It looks like you had about 4 hrs 45 mins, 27% battery used.
Estimate to 100% usage, 17 hrs 35 mins. Looks like you had 0% battery loss in standby, which is outstanding considering it was 8 hrs in standby. You have really great bonkers insane battery life.

I’ve noticed a thing; so my 11PM underwent the same charging habits, plugged out at 12am the night before I go to bed, and around 8-9am I’ll be left with 97%. That’s after checking the bus arrival apps and couple of alarms going off in the morning. The thing is, I get the same pattern of usage with the 13PM too. It seems like they both share some similarity in terms of standby battery usage? I would think the 13PM might have about 99% or something with the alarms and location-based apps.

What you are seeing is the max capacity. If you look at your battery using the Coconut Battery app on the Mac computer, you will see that the max capacity on your battery is actually above 100%, maybe 102% or 103%. I have seen it as high as 106%. So when you charge 100%, you are actually charging it to above 100% and it take some time before it drops below 100%. I have seen it stay at 100% for up tp 5 hours. The battery life is obscenely good.

I see. But if that’s the case, then technically the 13PM has to show a % higher than my 11PM with a 10% decayed battery - assuming all other factors remain constant. The rate of drain upon using both phones - the 11PM drained faster which is expected. But in standby/early morning quick use of 1-2 apps, the percentage dropped to similar numbers between the two phones.

It seems the 13 battery is being over reported. If you look at your battery percentage while looking at it in Coconut Battery app on the Mac computer you will see iOS over reporting the battery percentage by 4% - 5%. And as you use the battery more, you will see the over reporting drop < 1%. I think it is odd behavior and gives a rosy view on the battery life. But if you run the battery from 100% to 0%, the battery life is simply insane. So Apple is not misrepresenting the battery life, just a bit optimistic.

One other thing. If you shutdown and restart your phone, you will see the battery percentage drop several percentage points. This is iOS reading the actual battery percentage off the battery.

I won’t go to shutdown with the battery. It really stresses it out and ruin health. You already have a good battery I really wouldn’t do it. Video also aren’t good to consume battery. Run benchmarks or 3d games, that’s the way. Or use the camera a lot, maybe LiDAR scan your whole house

I stopped the battery drain at 14% and am charging it now to 80% again. You are probably right, I was trying to do something that could have adversely affect my battery. I appreciate you bring that up.

@coso Why isn't video not a good way to run down the battery?

You’re welcome. Video is not good because it drops screen frequency to 24hz and probably the A15 is optimized for that, it definitely is the lightest task you can do in your phone and the slowest battery drain possible, not realistical use. Using the camera, playing 3D games, now THAT really chews through your battery. You won’t see your long autonomy with those I bet..

Is it true what I’ve heard about a new iPhone needing a few days for the battery life/performance to improve? I’ve read that a new iPhone indexes, uploads/downloads from iCloud etc… and all of this has an impact on battery life in the first few days.

I’ve heard that from multiple people yet couldn’t find anything concrete about it. I know it was true with my M1 MacBook Pro but didn’t know iPhones were similar.

I absolutely LOVE my iPhone 13 though. I have the 256GB (Product) RED version. Such a gorgeous shade of red.

 

[Taz Mangus]

What I don’t understand is if I charge my phone to 80%, why does the battery percentage be off by 5% after I take it off the charger?

I understand why the battery percentage does not drop after charged to 100% due to the max capacity. It just not not make sense for 80%.

The file system will need to index if you do a restore from backup or a iPhone to iPhone transfer. That happens in iOS and macOS. The more files you have the longer the index takes.

That’s an Apple design decision. Psychological probably. Definitely not a bug in my opinion

 

[Quarric]

I’m finding it interesting that after running my 13 mini in low power mode for the last few days, how little difference I’ve noticed today in terms of battery drain with it not in low power mode. its literally just given me the 20% warning, at 8pm after coming off charge at 100% at 6:35am.
I don’t think that’s to bad for the little phone.

 

[GawrGura]

What’s with mine ?

Only 4 hours of screen time today and already down to 32%

Should I reset and restore? Can’t seem to find any rogue app.

How about location services? Do you guys have it on or off? How much does significant location impact your battery life?

I also have the phone paired to my apple watch btw
