4 Where to get good batteries?
Hello everyone,
I own an phone repair store(mostly iphone) and in the last month i am having big trouble to find good iphone batteries. I tried batteries from 6 to 19 $. All the new batteries drop very fast. Is there any way to test the battery when you install them in the iphone?
When i replace a battery i let the phone for 30 min and check if the percentage is falling. Now i tried 3 batteries and all are falling 2-3 % in 20 min(phone is just open, i dont use it). Is it because the battery is new and need to be reffiled some times or where is the problem?
How do you test your battery replacement? Is there any good way.
Hope someone can help me.
