OnePlus Nord 4 battery health suddenly increased from 92% to 99% — how?
I bought my OnePlus Nord 4 in March 2025, so it's been around 19 months.
Until recently, the battery health was showing around 92%. Today I checked it randomly and it suddenly shows 99%.
I haven't replaced the battery or done anything unusual. I know battery health is an estimate, but I'm confused about how it could increase by 7%.
Has anyone else experienced this on the Nord 4 or other OnePlus phones?
Could this be due to battery recalibration/software update, or is the 99% reading simply inaccurate?
Would appreciate any explanation or advice on how I can check the actual battery capacity/cycle count.
