Chosen Solution

Some of the small components of the logic board of an iPhone 4S are gone. It gives problems during charging. They are pointed with an arrow on the picture. What are those? Can I solve this problem by bridge the contact points? Thanks in advance.

Gauthier Top, I marked the components in numerical order. They are a follows.

  1. C293 100PF 5% 16 V NP0-C0G Capacitor
  2. R153 0.00 0% 1/32W Resistor part of BATTERY_NTC circuit
  3. R61 0.00 0% 1/32W Resistor
  4. C300 100PF 5% 16 V NP0-C0G Capacitor part of BATTERY_SWI circuit You should get away by bridging the resistors, but I would not bridge the caps. Hope this helps, good luck.
