Successfully saved a lot of money

The permanently installed batteries of Apple devices presented so far for me an expensive sword of Damocles is what on these devices always bothered me a little. So does an exchange with battery by a specialized workshop for the here under discussion iphone 4s ever up to ca 80.- and is due after 2-3 years, depending on the load.

But this is' s thanks to this battery here and YouTube for my iphone 4s past, because you easily by loosening the 4 screws quickly and easily can handle himself. Step by step instructions, can be found at YOUTUBE in large numbers. Easy! Can you also only once: there, if you look at that should not trust so.

Battery name
When 4s off. Batteries have been installed with different type numbers, the so-called APN numbers that are on the batteries. While there are some descriptions that describe successful type number change in the exchange, but I reckon that there are differences in the means of modified charging electronics here and have therefore rather just replace the exact type. Savings would anyway only marginally in the totals. For APN number determination must be solved 2 screws on the iPhone and remove the rear panel. Then you can see the APN number of the integrated battery (since then sthet "APN" followed by a sequence of numbers, that's it). These then stop the replacement battery raussuchen with exactly the same number.

OLD BATTERIES as new
If you read over and over again here at the various. Party to do so. Can only say that my no installation marks had, visually the installed is the same and the operation of my 4s from previously 1day brought after the first store to more than 3days back up. What do I want more?

EXCHANGE
Still, I'm moderately well equipped tool for electronics, I have the right tool for any 7.- here on Amazon in a comprehensive set concerned (if interested just search my review it), but because extremely small screwdriver, etc. needed to , What is needed is a "Miniaturtorx" (Pentalobe) for the casing, a miniature Phillips (PHILLIPS) for both battery terminal screws and a spatula. As the only special feature of the battery is in fact glued and must be bypassed with a small spatula something. The replacement but only just tricked so that arrived. Really easily.

SETTLEMENT
All very quickly and transparently by the seller here and in 2 days there.

So far so I can only recommend for the 4s battery here. Works really well.
