Battery percentage won’t increase despite charging

Dear iFixit,

After self replacing 3^rd set of new battery for 5s, I noticed the battery percentage won’t increase despite showing charging. I read similar problems and solutions, tried warming battery by hair dryer and charged to 100% once, but on next charging attempt same issue raised.

I read about missing F11 component, so opened the logic board and found it on place, but I doubt another component next to it to be missing. Please have a look on the picture and give your opinions.

I live in Nepal, where micro-soldering in unavailable.

Please suggest me what should I do; should I replace a new battery, or replace a logic board set with fingerprint sensor or should buy a new phone?

The missing capacitor is right on the battery main power line, but I’m not sure it should completely prevent battery charging. I’m confident @refectio @rany @benjamen50 will be able to put a word of enlightment about it. However if the missing capacitor isn’t the only cause, next in the list would be a tristar failure which requires even better abilities for troubleshooting. I wouldn’t bother trying another battery purchase in any case.

The missing capacitor is a decoupling/bypass capacitor and is used to filter out noise. As such, it has no real impact on the actual charging of the battery.

In the context of a professional repair, I would replace it but in your case, nothing need to be done about this.

Check FL11 again to insure it is solidly anchored to the board. Sometimes it is only partially dislodged and it wont show up visually. Use a sharp needle and gently apply pressure on it to see if it moves.

Should I try a new set of battery? Batteries, here in Nepal, are always Chinese knockoff, which costs from $5 to $15. Even if you are willing to pay premium, you cannot find a good genuine battery here, so always cheap one works.

Also, there is no authorized apple stores, mostly electronic shops will import from Dubai or Singapore retailers with hefty price tag.
