ios 8.4 breaks charging
Hi,
I upgraded my son's ipad yesterday to 8.4. To do the upgrade, as the battery was at 40% I plugged it into my normal charging set up - Anker 5 port 40w charger, USB extension cable and Apple lightening cable so I know this works. After the upgrade I noticed it was no longer charging. If I removed the lightening cable and re-inserted it, the charging light briefly flashed then went out. If I removed the USB extension cable, so directly connected the Anker to the lightening cable, charging then resumed. To test things out I then used the genuine Apple brick and that was OK with the lightening cable but not the USB extension cable as well. I then replugged the lightening cable back into the Anker charger and that would no longer work. I tried plugging the lightening cable into my Dell laptop and again the green charging light flashed on then reverted to not charging. Note I can charge from the genuine Apple charger and lightening cable so the device is still usable until the battery dies but I really need to be able to use an extension cable.
It seems like ios 8.4 has changed some parameter (voltage?) required at the lightening socket to allow charging, but it must be outside Apple's own specification as they say you should be able to charge from a PC/Laptop USB socket.
I am in serious difficulty now. My son is disabled with severe learning difficulties and needs the longer lead so he does not drag the mains cable round with him or put undue strain on the lightening cable. The longer lead is also needed so he can use it on long journies in the car to reach the car charger as the batteries don't last a long journey.
Please can I have an urgent fix for the problem?
TIA,
Nick
PS I am not sure which category to post into as I dont see an ios specific category, so if I have used the wrong one, please can you change it?
