Hello, Can anyone tell me what this means? Or if it's normal? I'm seeing about 10% battery drain per day on sleep, and pmset -g log shows wakes nearly every minute. 2025-06-10 17:10:35 -0700 DarkWake DarkWake from Deep Idle [CDNP] : due to smc.70070000 wifibt SMC.OutboxNotEmpty/ Using BATT (Charge:94%) 5 secs 2025-06-10 17:10:43 -0700 DarkWake DarkWake from Deep Idle [CDNP] : due to smc.70070000 wifibt SMC.OutboxNotEmpty/ Using BATT (Charge:94%) 6 secs 2025-06-10 17:13:49 -0700 DarkWake DarkWake from Deep Idle [CDNP] : due to smc.70070000 wifibt SMC.OutboxNotEmpty/ Using BATT (Charge:94%) 8 secs 2025-06-10 17:14:01 -0700 DarkWake DarkWake from Deep Idle [CDNP] : due to smc.70070000 wifibt SMC.OutboxNotEmpty/ Using BATT (Charge:94%) 6 secs 2025-06-10 17:14:10 -0700 DarkWake DarkWake from Deep Idle [CDNP] : due to smc.70070000 wifibt SMC.OutboxNotEmpty/ Using BATT (Charge:94%) 6 secs 2025-06-10 17:15:01 -0700 DarkWake DarkWake from Deep Idle [CDNP] : due to smc.70070000 wifibt SMC.OutboxNotEmpty/ Using BATT (Charge:94%) 6 secs 2025-06-10 17:16:31 -0700 DarkWake DarkWake from Deep Idle [CDNP] : due to smc.70070000 wifibt SMC.OutboxNotEmpty/ Using BATT (Charge:94%) 6 secs 2025-06-10 17:18:07 -0700 DarkWake DarkWake from Deep Idle [CDNP] : due to smc.70070000 wifibt SMC.OutboxNotEmpty/ Using BATT (Charge:94%) 6 secs Looking at one section of them: 2025-06-10 22:00:46 -0700 DarkWake DarkWake from Deep Idle [CDNP] : due to smc.70070000 wifibt SMC.OutboxNotEmpty/ Using BATT (Charge:90%) 6 secs 2025-06-10 22:00:46 -0700 WakeDetails DriverReason:smc.70070000 -

Clearly not percentage, but the units don't seem to be specified... The real problem we have right now is that, with macOS 15.5, our suite gets a huge amount of "energy impact" points, even though diving into it, it doesn't seem to do that. The most telling example I have of that is: I ran each of our daemons from Terminal, unplugged my laptop, closed the lid, and let it stay there for 8 or 9 hours. When I woke it back up, Activity Monitor claimed it had 2,000 units or so, but after opening all of the disclosure triangles, none of the processes (including the hand-started daemons) used anything close to that. Also, the battery had almost no drain on it. We're getting complaints about this, so I'm trying to figure out what, exactly is going on, but I never looked at the power stuff internally so I don't know how to read the diagnostic files.

Hello. We have several apps, that use battery information, such as charge level and battery charge events. Since iOS 17, instead of report every 1% of charge, all API return an approximate within 5% value of the real value. As a result, that created a lot of issues with our users. Most of them, and at this point its around of million plus users, are not happy, because they will have to wait for the app to return information for literally hours... Please fix this, and even if you wont allow us access to real time data, like in Android devices, please at least return it back to be precise and at 1% of precision.

I am reaching out to inquire about the implementation of an energy monitoring solution similar to Xcode's Energy Impact tool for iOS apps. Specifically, I would like to understand the following aspects to address issues like overheating and rapid battery drain: How can we achieve monitoring and calculation of CPU, GPU, and network usage over a period of time within an app? How is the current energy consumption level of an app determined? Additionally, how are the weights for various factors like CPU, GPU, network, and location usage allocated when calculating the overall energy impact? Any guidance or resources you could provide regarding these questions would be greatly appreciated. Thank you for your assistance.

Since running 18.4 beta 3 my phone doesn’t stop charging at its pre determining % it’s set at 80% and until now has always held at that percentage but since installing beta 3 it’s gone to 100% and held at that when charging overnight anyone else experiencing this?

I just bought my iphone 15 128gb last august 2024 and it’s already in 93% battery health. Whenever my battery percentage drop to 29% my battery health will also drop 1%. For example, i forgot to charge my phone, the battery health percentage is 94%, because i forgot to charge it, it is currently in 29% battery percentage. When i look up the battery health percentage, it is now 93% Btw, i use 30% - 80% charging tech. Sorry for my english. English is not my first language.

It looks like, for some reason, our apps are using a bunch of power sometimes. sysdiagnose has this in the power log: Never mind. Including the output of sysdiagnose has "sensitive language," and it won't tell me what is sensitive, making this a waste of my time. ETA: Ok, I I can attach the file: power.log I've gone through the energy documentation, but it seems geared towards embedded, not macOS, so I'm not sure how I can figure this out more. The extra problem, of course, is that we have a network extension, two daemons, and a GUI app. 😄

So the battery level value is in accurate returns the battery percentage in multiple of 5 values e.g. battery percentage is 42 but the api returns it as 40. So please fix the issue if possible because i checked that the devices running iOS versions below 17 appear to be working fine.

Currently i am using an iphone 15 pro which is just 7 months old but it was good till this month it was at 97% even after using more than 6 months, but in recent fews days it is regularly dropping by 1% every day and now it is at 89% only with 10 to 12 days it dropped by 8% . Is my battery defective or something is wrong with my phone . bcoz of this i am very upset because of this bad decrease of battery health . i have heard it is normal to degrade by 1% monthly but mine is dropping daily its soo frustrating. and if my battery reaches under 80% within the warrenty period? will get a free battery replacement from apple or not ? I don’t have apple care+ . But its under 1 year standard warrenty . please reply apple as its soo frustrating

Battery health reduced to 89 from 98 within 2 months on iPhone 15 Pro and Cycle Count is just 314. Is it the software update doing this?

what do i do is it going down too fast?

six months have passed since I bought this iPhone 13. till 3 months it was having the battery health of 100% but now it is draining rapidly. It drained to 99% in November.at the beginning of December it was 98%. on 23 December 97% and now on new year its 96%. can anybody tell me why ?

I am building a watchOS app with iOS companion app. The watch app needs to track the heart rate during the night or while user is sleeping. And the desired frequency of measurement is 0.2Hz (every 5 seconds) For this I am using the HKWorkout mode with mindAndBody session. While it works fine, One of the main issue is: after about 6-7 hours of usage, the battery on the watch drains between 40% (Series 9) and 100% (series 7, I think) My questions: Are there any other option to track user's heart rate without workout, while the app could be in background? Another side effect of this workout mode is, Even if we choose not to save the workout in HealthKit, the Activity rings gets populated by this mindAndBody session, which makes it when the user is waking up, the bar is already full, This is not desired. Is there any option to specify for ActivityRing skips this? Highly appreciate any help in advance. Cheers - Prakash

Recently after the update of iOS 18.0.1 my iPhone 15 pro max drains very fast if I'm in normal usage only at one day i.e. on 19th of October I checked my battery health it shows me 99% as of today i.e. 30th October it is 96% I'm bit confused is there any issue like this to anyone i would like to know.And is there any solution for this?

In October the 9th I had 97% battery health and after not even a month (on the 28th October) my battery health went down to 94%. Anyone knows why ? I haven’t been using my phone more or charging it more than usual. using an iPhone 15 pro max. This is really concerning !!! 3% in less than a month?

I recently bought a new iPhone SE and transferred all of my data. I want to keep the old iPhone and have removed most of the Apps. However when I charge it fully at night, the battery is almost dead the following morning. This was not the case before I bought the new phone. When I check the battery app, it doesn't indicate any use that would explain why the battery is almost exhausted.

I bought my phone on April 1st week, 2024. In September battery was 96% cycle count 260. Now after 1 month battery health is 90% in cycle count 300. I am using my phone everyday4-5 hours and maitaining 20-80 charging. I didn't play any kind of games in my device. My question is why apple claim 1000 cycle count and 80% will be? And how to solve this issue?

I have an iphone 15 pro, it’s only 4 months old and the battery health has dropped by 2%(98% now). I don’t let my battery drop below 25% and change only to 80%. I use an original apple charger and cable. The total battery cycle count is only 117. I don’t understand why it’s dropping so quickly. Can anyone help ? Thanks

What are the possible KPI requirements set by Apple AI for cellular networks, e.g. regarding latency, throughput or jitter? What is the expected effect on iPhone energy consumption?
