software issue or charging problem

My iPhone 4s started having issues with the battery last month. ("Newly"installed before last xmas). I tried a "soft" recalibration by leaving it a long time to discharge and then charging it, but it never went beyond 1% according to the iphone, while having a good duration.

After a very long discharge, I started recharging it, and I wonder whether I screwed it by turning it off while it was rebooting. After that it never recharged...

I finally opened it to take a look, and I found a tiny smd (looks like an 01005 package) loose inside. I guess it is probably a resistor, although a can't make out any lettering on it. From what jessabethany said on an iphone5 thread, the phone should probably work even without this smd in place, but I wonder if it breaking off is connected with the charging problem. I don't have micro soldering tools, and cannot see yet where it came from (I don't see any obviously empty pads on the logic board). I have some pictures, and would highly appreciate any advice.

Here's the best picture taken so far, and cannot spot anything missing. Can anyone help???

You cannot draw any correlations across device models. What is critical for one device may not be for another, or completely absent in a third. Post a picture of where you think this loose "resistor" fell off from. Some components are critical and their absence can kill a phone. Others are like your toes. You can loose one and still live normally. Awkward, but otherwise fine.

I haven't been able to spot where it could come from, and my links to the pic of the smd are not going through moderators...

but many thanks!

Thanks a lot for your replies. I'll get on with it and let you know what I find. I'll add now the only pic I have of the ca. 1mm smd.

You'll need to upload a high resolution image so that we can zoom in. Also, when you want someone (or more than one) to know that you have added information, use their @ username to notify them (mine is @refectio). For example, this new answer you just answered does not notify me, I just happened to see it because I bothered to dig a few pages deep.

As @rany commented, you really need to identify where this component came from. My guess is that it is R61 (alright everyone, place your bets! ); it is involved in the gas gauge line, which would explain some f the symptoms you are seeing.

Right next to the battery connector, there is a row of SMD components, a group of 2 and a group of 4. R61 is in the group of 4. Check that to see if something is missing (magnification will help). Otherwise, it could be anywhere but more likely next to one of the connectors (they can be pried off by accident when removing connectors).

Let us know.

@refectio , just to add to Minho good ans., attached link may help, if not just ignore. Small component broken from the logic board

L Pfaff さんによる2017年5月25日

Good research @lpfaff1 . For the OP, R61 would be third on from the left.

Minho さんによる2017年5月25日

Nothing missing there. All the 6 smds were visible.

So I need more time to try to find where this component came from...

Thank you all and will keep you posted!
