I find out that when I charge my iPhone, if I don't charge it to 100% before I pull out the charger, sometimes the battery will leak out very fast.
The leak manifested in these ways:
- From the iPhone setting, I can see that the usage time since last full recharge is the same as the time now minus the time I pull out the charger. This means that the phone is effectively being in used right after I stop charging it, even though there is no one using it.
- The iPhone battery decreases at the rate of 10% per hour, much more higher than the normal idle decreasing rate.
- If I restart my phone, the battery % will still remain the same. So this means that the battery loss is for real.
- If I restart my phone, the leak stops. The battery now decreases at normal idle rate ( which is about 2-4% in 8 hours time)
This problem is intermittent, and I can't reproduce it for sure but it happens from time to time.
Any idea how to fix this?
