Are you discharging the battery to very low levels regularly? That wreaks havoc on capacity. My two year old iPhone still reports 90% of its maximum capacity, but I can count the number of times I let it go below 20% on the fingers of my hands.
- tjoff 8y agoI'd say that 10% is very common, sometimes 20%, somtimes less than 10. But to combat this my previous phone was a moto z with a battery-mod that kept it at 80%. But the constant charging/discharging was probably too much for it. After 20 months the battery was beyond useless without the battery-mod. And I only did the above to be able to prolong the life of the phone, yet it lasted much shorter than any previous phone I've had.
- leetcrew 8y agoyou also have to consider the climate that the user lives in. one can be very diligent about discharge levels, but if you spend a lot of time outside in the heat, you are subjecting the battery to worst case operating conditions a lot.
