iPhone 4s missed two components near battery connector

[calamar0]

Hi guys I need your help, i've tried to solder the battery connector but i've missed/broken two components. I think they are 2 diodes but i'm not sure.
Could you help me to identify the correct component and can you tell me where i can buy them?

Now i can power on the iPhone only when it's in charge.





Thank you all

I've found the schema for the iPhone 4s and that components are two capacitors C294 and C295. Where can i buy these capacitors?

what problem in your phone,,,
i think capacitor are no rizen of any problem
they create problem if short
butt no problem if removed

The first problem was the battery connector that i've tried to resolder but during the soldering i've removed the capacitors. Now i can turn on the iPhone only when it's connected to the power adapter, no signs of life only with battery and no battery indicator on screen.

Thank you for your reply!

Remove the capacitors, and resolder the battery connector, use plenty of flux, im sure it will solve your problem.

Thank you guy, I'll try and I'll post the result.

Your problem is not on the capacitors but on the fuses near those capacitors. Check if you have continuity on those two components.

Which fuses? Could you show me?

Sorry i said fuses but they are 0ohm resistors, but they act as fuses.

This is the components :

I've checked all connections from the logic board battery pins to fuses/capacitors on the scheme and all work correctly. I've also removed the capacitors like that I've broken like suggested before without success.
The iPhone still turns on only with the power adapter, no signs of life/battery indicator only with battery.
Do you have any other suggestion?

have you found a solution for this? I'm on the same boat

@calamar0 : when you turn on the phone using the charger, it stay on or reboot ?

If stay on, when you press the power button does it react ? (screen off, screen on, etc.)

Yes it works perfectly except the battery percentage that is ever at 100%. It seems like it doesn't recognize the battery.
Like I've said before it's very strange because I've tried only to resolder the battery connector, before that moment the iPhone has worked fine.

Thank you man for your support

No solution at the moment.
