    Hey forum,
    I'm hoping you can help me with a problem that is driving my crazy. At this point, I'm just super curious as to what could be causing my problem. Here's the deal..
    I am still currently using a Samsung S5. Long and short is the charging port went bad, I bought a replacement phone but it was locked to a different carrier. I went back and forth with returning it and just said f it...i'll keep it and use it as my battery charging phone and what with battery life I have kept 2-3 on hand so I can just keep swapping them out. Yeah I know...anyway a few days ago, one of the batteries that were working fine will not boot up my phone (it gets to the Samsung logo and shuts down). Here's the thing..it works fine with the other phone (takes a charge and starts it up). I have done a factory reboot, cleared cache, drained battery, etc. The only thing I can figure is there must be some sort of compatibility thing going on. Any suggestions are appreciated. Thanks.

    Just to clarify, are both Galaxy S5 phones? You refer to a 'replacement phone' but is the replacement also a S5 or a different model?

    How did your charging port go bad? Have you tried cleaning it?




    I have several Note 4's o er the years. I also had the same experience doing the swap batterys back and forth. I have no idea why the same battery booted on N4 and didn't boot the other, although sometines it did. Weird Right? Anyway, I cleaned the loose usb port with a thin plastic pick. Small enough not to push the center part of the phone usb port (moves freely). Afterwards, I could pug in the phone and slightly hold the charging cable a certain way until it showed a charge. When it did I could successfully power on my N4 with the battery that previously did not boot the phone.

    The major difference between your two S5s will primarily be the motherboard inside. Back when the S5 was in its day, T-Mobile used (and uses) a GSM-based cellular network and Sprint primarily relied upon a CDMA-based cellular network.

    That's thankfully all becoming just history as the carriers have moved on to LTE and (upcoming) 5G (... and T-Mobile has recently bought out Sprint anyway), so differences in the two phones will be mostly things like the cellular radio and antenna controller chips on the main firmware board. But there are not separate Galaxy S5 batteries for different carriers, they're pretty much universal as far as compatibility. The differences being build-quality, capacity, etc. So that does add to the mystery of the problem you're having, there's a missing piece to the puzzle that is yet to be determined.

    As an aside, looking up your phone model on the iFixit site, it does show the charging port is part of a separate daughter-board. If you're comfortable with tearing down your phone, replacing just that daughter-board is relatively less invasive than with a lot of phones where the charging port is soldered directly onto the motherboard.

    Yes I have to no avail. Some metal fragments had come loose so it needs to be replaced I'm sure. But thanks!

    It really wouldn't be practical to buy all the tools I need to attempt this EVEN if I was inclined to try this, but thanks for your input.
