Hello
I have an iPAQ h5150 that has a damaged connector so I can't plug it in to charge it. It works OK otherwise. I have the charger with the male post connector and would like to solder in some wires and a female connector (e.g. from Radio Shack) just so I can charge it. Does anyone have information of how I can wire this thing up to do this. Alternatively, does anyone know how to charge the battery externally? There's 5 pins on the Battery that connects to the iPAQ, and I would like to know how I can apply the charger's output to the battery to charge it up. ANy schematic diagram availble would be appreciated.
Thanks
Mike
Is the charger terminals on the cradle damaged, or the slot in the Ipaq itself?
You can buy charging tips that fit this model on ebay for about $9.00, that slide over the barrel plug on the ac adapter. If the charging slot is ok you could charge that way.
My phone won't charge - the cable wobbles in the port now, and looking into the port I can see a copper pin bent flat against the back of the port. I tried fishing that pin out with a staple, no dice.
My question is, how hard would it be to replace the micro usb port using a $6 replacement from ebay? I'm sure I can disassemble and reassemble the thing without a problem, but I'm worried about soldering and desoldering - how intensive is it?
I've got like 50% battery left. I know I can buy battery chargers and keep swapping out the battery, but I'd rather not do that - this phone is my primary alarm clock Maybe it's time to say goodbye and upgrade to a higher end phone.
1. Does it matter if I charge and use mobile at the same time?
2. My usb that goes to mobile has 4 pins. One is missing but it works fine so not big deal but wanted to see if it's normal or mine is with defect. Got other mini usb adapter from external battery (9000mAh Mobile External Battery Power Charger with Cell Phone Adapters) and it was much harder to put/take out in phone so I compared with original one and saw original is hardly noticable thinner inside and is missing one pin.
Maybe I shouldn't use that adapter, not to damage mini usb on note.

1. I would advise you not to use while charging. If i'm not wrong using it while charging results in the phone charging and discharging at the same time and that's not good for the device.
2. I think all original Samsung chargers have 4 pins. Even mine has 4 pins.
Thanks
Since I bought 6000mAh external battery for brother, I tried his mini usb adapter and it fits like samsung cable. Looks like I got bad adapter, will throw that.
I'm thinking about upgrading my P8 lite to include wireless charging, but I'd like to put the charger inside the case.
Does anyone know of the appropriate test points for +5v and ground to the charger?
Thanks
I didn't open up my phone, but I don't think they have any??? Myself, I would just buy a cheap Qi charging adapter.
For ground you can scrap the PCB, for 5V just follow the battery connector, you'll have to remove a couple of screws maybe, I did it because I had to unplug it.
Whether it be an internal wireless receiver or external usb c receiver. Most external usb c receivers are at the minimum 3.9" tall which seems to be the issue.
You can, but...

You can get an Ultra Thin USB-C Qi Wireless Charging Adapter, and you could install it on the phone and keep it hidden and in place by getting a Razr phone case. I plugs into the USB-C charging port and the thin flat ribbon cable has a 90 degree bend to it. I used this coil adapter before on a convention smartphone years back, the only drawback is that your USB-C on the phone will be occupied by the coil. Wireless charging is slower than traditional USB-C charging.
Cheers,

I'm aware of that but the issue is most of these are at least 4" in height which would cover the fingerprint sensor.
Find the shortest version, and if need be you can cut it to streamline it.
The ribbon cable has some flex to it, and if you use a heat gun you can bend the flex cable like an accordion to reduce length. You could also diminish the height of the coil pack by cutting it. Since the phone has a glass back, and your "sandwiching" it with a case, there is no fear of creating a short when charging.

Wouldn't cutting it cause it to malfunction? Also, do you mean use a heat gun to fold it in half? Do you have illustrations?
I think he meant to cut the edge to make the fingerprint reader completely clear, but not to cut too much to avoid the coil, and I'm assuming he meant to fold the cable in half.
Another point besides the charging speed is the heat that the coil produces.

Just a few questions. Where can the wireless adapter in this picture be purchased (link)? It looks like the usb dongle is too long to fit properly on the phone since the adapter is shifted below the fingerprint sensor. Does this wireless adapter work good on the device without overheating?

Link does not open... Please supply some info to find it
I see this for Barbuda nut only comes with lightning connector... would need USB-C ＆ only 5v so... I would still buy one at that folds its level because I don't really care if it's fast charges because I leave the thing on the stand overnight and it may actually be better for the battery to slow charge.
I played around with this as well. I was able to trim the one I'll link below to the right size. The key is to not cut the coil, the rest seems like it can be cut without a problem. In the end I didn't like not having access to the USB-C port. But it was a fun pandemic project.

As for the one I cited above with lightning connector... maybe someone here knows how to suggest they make one for USB-C ??

I'm a little late to the party here, you can solder in a wireless coil to the inside of the phone. The best coil I could find is this 7.5W (5V 1.5A) coil. There's a 10W (9V) option, but it would require addition circuitry to use in a phone.
The external plug-in solution is by far the easiest option, but it has too many flaws: blocks usb port, protrudes too much, fragile- must be kept inside a cover to protect it, most put out 2.5-5W, and it looks horrible.
Heres the link for the internal coil. If its unavailable at the time of reading this, on aliexpress, search for "7.5w wireless coil".

And here's a youtube link showing installation. You can skip half of it. aim is to tap it to the ribbon carrying the charging from the usb.
It does require some understanding of basic circuitry and soldering... not for everyone.
Ive just bought the new Razr 2022, and will be installing it on that.
Just keep in mind that the RAZR has two batteries, and getting it apart isn't for the faint of heart.
It's also one thing to get apart, and another thing getting it back together..
Just advice, but definitely watch anything you can get your hands on before tackling, and good luck.
