In my original battery imiPhone 4 APN 616-0512 was printed. For best compatibility and avoid problems the APN of the new battery should indeed match. It should probably be noted that the APN 616-0512 should be the same as the APN 616-0520 and therefore supposedly both should work in my case. Let's see, I'm curious.
So I ordered a Li-Po battery with smartec24 for iPhone 4 with the APN 616-0512. Shipping via Amazon, with Prime without Returns and as usual the next business day at the packing plant! Perfect. From packaging ago was solid in the pack slipcase Amazon turn a small box labeled "smartec24 (R) iPhone4 ...- 02-501 // 1420 mAh New" and then in an anti-static bag for e-technology the Li- Po battery.
I have received übrigends latter APN 616-0520. In appearance absolutely undamaged and ok, a little scratch is forgiven, of course, because it sure does not affect the function. The plug for plugging the iPhone absolutely identical to the original and the same high quality. Even the text printed on the battery looks absolutely like original commodity.
To read the battery's info I came across iBackupBot (Free Trial Version).
First I read the old battery and receive the following information's about:
CycleCount / charge cycles: 820
Design Capacity / Maximum Capacity: 1420
Full Charge Capacity / current Maximum Capacity: 1058
Then replaced the battery, read the new battery and you get this info's:
CycleCount / charge cycles: 21
Design Capacity / Maximum Capacity: 1420
Full Charge Capacity / current Maximum Capacity: 1386
What should I say? The 21 charging cycles are really as good as new in my eyes, and to be proud of. After installation everything works as promised well! The iPhone charges the battery and I'm curious how long it lasts. For the price really hammermäßig awesome !!! Buy at smartec24 and Amazon? For me happy again.
