The iPhone always draws its power from its own battery. However, when connected by USB to a MacBook Pro, it will at the same time charge the battery. So depending on your use-case, it is commonly possible to run the iPhone indefinitely in this mode. Remember to power the MacBook Pro from its charger, and ensure that the MacBook Pro is not so heavily taxed ...

Everything seems normal to me. Batteries are much more complex than most people think. There are many factors such as heat/temperature, actual charge, power draw, lifecycle/age,... that contribute into "inconsistent" measurements. Why design capacity is not consistent, sometimes 74%, 75%, 80%? This is completely normal and every battery ...

Here is a post suggesting disabling the Thunderbolt Ethernet Driver solves the issue. Another post suggests the nocrashmbp utility which says 2013-2015 MacBook Pros are susceptible: The CPU has several power states and voltages. Some CPUs have become unstable at the extremely low voltage on one of it's cores. The CPU will sometimes briefly dip into that ...

I would suggest buying a caravan power module which can run from mains, a solar panel or DC 12v (and charge a 12v battery), all in one box - they can deliver 12V 40A to/from the battery... and if Your laptop is powered from USB C do not use an inverter, use a 12v to USB C PSU instead. I use a Shaudt CSV409 and a 100Ah 12v LiFePo battery from Fraron (with ...

Yes. You can charge your iPhone via your MacBook irrespective of whether it is running on battery or power. Yesterday when I plugged it in, the iPhone wouldn't charge from my laptop. It could be possibly be due to a faulty cable or port. Try cleaning the port or any dust or other accumulation and/or switching to a different port. You can also try ...

Your MacBook Pro is a sophisticated product, with very capable power management and controls to prevent over-heating. It is designed to be used, and to work hard if needed. You do not need to monitor the temperature, and you cannot damage your computer through use. Intel CPUs can run over 100˚C quite normally. Your Mac has fans, which will speed up to ...

Yes you can. Your iPhone will draw the appropriate amount of power from the MacBook USB-C charger. For more information, such as which iPhone models and which Apple chargers can be used, refer to Fast charge your iPhone on Apple's website.

I solved this by using my MBP's factory power adapter instead of my wife's MBA's. It seems to charge just fine (albeit, slowly), but for whatever reason causes this kernel_task issue. I did not try it in the right ports (they were unavailable). Apologies if this solution is already here

These terminal commands will show sleep/wake activity since the MacBook was last powered up. pmset -g log | grep -e "Wake from" -e "DarkWake" -e "due to" pmset -g log | egrep "\b(Sleep|Wake*|DarkWake|Start)\s{2,}" They both extract data from the power management log and produce very similar output. Try one or other (...

Your new M1 Mac not only has sophisticated battery management software, but is also one of the most efficient laptops on the planet. You don't need to do anything. Just use it as you need. There is very little you can do to improve (or worsen) the battery's life. Of course, keeping it plugged it will reduce the number of charging cycles, but in all ...

Just use the Mac! But you can help it with: Make sure "Optimized battery charging" is on. System Preferences > Battery. Avoid having power connected all the time, though this is mitigated by macOS and the setting optimise battery charging. Avoid letting the battery go below 25%, but if needed sometimes don't worry. If you are going to turn it ...

I had the same problem with MacBook Pro 13in 2017 model. But the battery drain and laptop being warm happened only when the laptop was sleep and the charger was connected but turned off. I didn't observe the problem when the laptop was disconnected from the charger during sleep. So, I guess it must be an electrical issue(earthing).

The maximum count of your unit is 1000. 2 is normal for new unit. You have 998 cycle count before you reach the maximum cycle count. Once you reach it you need to replace the battery.
