This is a 50% DoD and is considered best possible practice to prevent lithium-ion dendrite formation.
Updoot for good advice.
Proof:
If you don't mind clarifying, what do you mean by DoD?
Depth of Discharge, sorry -- 0 to 100 would be a 100% depth (the entire battery), 30 to 80 is 50%.
What kind of software creates this plot?
Looks like AccuBattery.
It's AccuBattery
ThanCC!
Missed opportunity to call it "AkkuBattery" for all the dual language pun enjoyers out there 🎩
The really nice thing is that the larger phone batteries get the more you get to use at 50% depth of discharge. My phone is 5,000 mAh and so I get to use 2,500 mAh of it. Once average phones start getting 5,500 mAh, that will mean I will be able to use 2,750 mAh. 250mAh may not sound like a lot, but it can go a decently long way.
Not entirely true. "Best possible" would be left plugged in and charged to 50%. Next best would be 49-51%. Then 48-52% and so on.
Also it's not that difficult or expensive to swap a battery and not really worth the stress, in my opinion.
Well, you are absolutely correct. A 1-2% DoD is something for like, the Voyager Probe though, not a smartphone :)
What did you actually gain here? With my Pixel 7 it looks almost the same with 3.1% capacity loss per year without taking any special care of my battery. Is my phone an outlier or does it just not matter? And I almost exclusively charge with wireless.
I charge wired (high speed, 18-22W). Wireless is known to be a lot slower and theoretically gentler on the battery.
I also use the phone heavily, like a computer, I'm a "power user", so my battery thrashing is higher than average.
Us having the same durability lost on our engine despite me driving double the miles is a good analogy.
To my knowledge wireless charging is harder on the battery because of the heat it produces.
