How much does a battery degrade in a year?

And batteries degrade even if you don’t use them. According to battery-testing firm Cadex Electronics, a fully charged lithium-ion battery will lose about 20 percent of its capacity after a year of typical storage.

Why is my battery capacity reducing?

Your battery’s maximum capacity A battery will have lower capacity as the battery chemically ages which may result in fewer hours of usage between charges. Depending upon the length of time between when the iPhone was made and when it is activated, your battery capacity may show as slightly less than 100%.

How do I stop my battery from going down?

How quickly do phone batteries degrade?

However, on average, a cell phone battery loses 20% of its capacity after 500 charge cycles and usually becomes unusable after about 2500 charge cycles. According to Apple, the iPhone batteries are expected to last at least 500 full recharging cycles before the capacity drops under 80%.

Do phone batteries degrade over time?

Battery manufacturers say that after about 400 cycles a phone battery’s capacity will degrade by 20%. It will only be able to store 80% of the energy it did originally and will continue to degrade with additional charge cycles. The reality, however, is that phone batteries probably degrade faster than that.

How long does battery health stay at 100?

Is 89% a good battery health?

According to Apple, a normal battery is designed to retain up to 80 per cent of its original capacity at 500 complete charge cycles when operating under normal conditions. If your iPhone’s battery maximum capacity is under 80 per cent, then its health has been significantly degraded and it needs replacing.
