Hello
I think my phone has a broken U2 IC, When I plug the phone into the power outlet it shows that needs a charger.
When I connect it to my pc nothing happens, not even a connection sound.
Is this normal for a broken U2 IC?
Thanks for the help.
Es esta una buena pregunta?

Yes, that's typical for a blown U2. But it's also typical of a dirty dock/lightning connector or a faulty dock connector flex. So first clean the dock connector with an alcohol wipe or similar, and if that doesn't work try a new flex. Replacing the U2 IC is beyond most people's abilities - it may look simple in Youtube videos but it takes a fair bit of skill and experience.

Also, as a follow-up, the cause of a blown U2 is almost always a faulty charger or cable. So dump/replace your cables before reconnecting that phone or trying to charge any other phone. Also, if you read around you'll see it's possible to solder in a jumper to bypass the U2 IC. Don't do it - if you have another power supply issue it will be much, much worse for you.
i have a also a problem, restarting when its sleep mode but while I using my phone its normal nothing happen. When its sleep mode it is restarting over and over again
Charging the iPhone by connecting it to a computer VIA the USB to Lightning adapter is awfully slowly. Just get a wall charger adapter (the USB connects to it and it directly to the wall. Two posible problems you can find even if using the wall charger are:

iPhone 5s
- I insert the charger lead when the phone is off, the phone starts up with apple logo and starts charing
- When I insert the charger lead after a restart or reset the phone responds instantly - as it should
- But if I take the lead out and insert back in, the phone does not respond: no beep and no electric charging icon next to battery icon. But if I leave the charger in, it the phone responds after about couple of minutes, and starts charging
- If I take the lead out from the phone wil battery fully charged the battery drains in about an hour or so even when the phone is not being used.
Kindly help!
