Thread: USB Power Adapter fails at 97%

  1. #1
    Default USB Power Adapter fails at 97%
    Hi folks

    I bought a new USB Power Adapter from Apple (the new flat, long one). However, when my iPhone 3GS is almost fully loaded (>96%), the iPhone starts to randomly detach the cable, then reattaches it again. This happens every couple minutes and produces the same sound that you hear when you plug in the USB cable. This happens only with the new power adapter, when I use the old one that came with the phone it works perfectly fine. I also verified if there is a physical problem, but the cable and the adapter remains stable.
    So my first thought was the power adapter and I went back to apple and replaced it. At home, same issue again. . The Adapter shows as well 5 Volts and 1 Ampere output, which is the same as the original one. Still I made some tests with my old iPhone 3G and there it seems to work fine (two tries up to 100%). So I went back to the Apple store and told them, that they sold me a 3G edition, but I was told that it also works with 3GS. They gave me another new one and also a new cable. But back home, I had the same issue again.
    Has anybody noticed such behavior as well? When I let the battery drop to 10%, it loads without any problem up to 97% or so, then starts to beep again. It also happens when I let the phone drop only to 80% and the load it, so it is not a time issue.

    Here is my syslog with the Power entries (“RiP” is the name of my iPhone), any idea where to look for?

    Check to see if the iPhone is under warranty, if it is set up an appointment with apple, they have wall outlets there so u can show them the problem, Apple is stupid in slit of ways, I bought a charger it works but only if I don't have any applications running on the iPhone which means that charger is no longer supported on the new firmware it's apples way of saying buy a new charger, but it sounds like it's a software issue on the iPhone make sure the bottom is free of dust and other contents, when the iPhone gets up to 80% I believe it starts a trickle charge, sounds like this is kinda causing the issue

    What's a trickle charge? Does it just charge slower?

    No, I am on 4.0.1, jailbroken with many apps installed.

    Last night I borrowed a non-apple power adapter from a friend and also with that one, it works perfectly fine.

    So the iPhone must do something when it comes close to 100%. Just now, the alert just started at the moment it reached 100%.

    Apple told me, that I have to upgrade to 4.1 and remove the jailbreak, so after replacing 3 power adapters, I can not expect any further support from them.

    Has anyone already bought that new small hexagon power adapter 1.8"x1.4"x0.6"(4.5x3.5x1.5cm)?

    Thanks,
    Rollly
