Is iOS battery health overly generous?
I noticed this on the first release that battery health (beta) was released to the public. I checked coconut battery on my Mac and it told me my iPhone’s battery was at under 90% design capacity. Meanwhile, iOS battery heath told me was in the mid-to-high 90s.
Today, I made a call for about an hour and streamed some music for another hour and the phone fell to around 50%, that’s about what I expect, but then I took it out of my pocket to charge and it was suddenly at 1%. It sat in the charger (USB connected) for about half an hour and it was up to 75%.
That’s classic battery is failing behavior so I checked iOS battery health and it’s telling me I’m at 90% maximum capacity while Coconut Battery is telling me it’s 81.9% capacity.
Based on the behavior I’m thinking Apple’s reading is being overly generous and Coconut is more accurate. How do they compare on your devices?
P.S.. When this started happening, I followed some steps I read online about re calibrating by fully discharging, charging and repeating but that didn’t help much.
The phone performance has been very nice since the update so I’m not complaining about battery gate so much as I’m questioning the accuracy of the battery health (beta) reading.
