Remove battery - Hard wired - Samsung Galaxy Tab A series Questions & Answers

Has anyone removed the battery from the Tab A and hard wired in a power supply? Looking to install mine in the car, but OTG + charge does not work, which pretty much means it's a non starter.
While I am tempted to try the Lavalink adapter, reviews of it are not exactly stellar. The battery looks like it has 2 red, 2 black and 2 yellow wires. I am not sure yet what the yellow wires are for, but would assume red and black are positive and negative. If I go this route, I plan to buy a 2nd battery to use the little pigtail on order to be able to put the tablet back to stock if needed.
Anyone done this to their tablet?
Thanks.
Edit: Took the tablet apart, nope. The DIY I read about taking the back off showed 6 wires coming from the battery (2 x Red, Yellow and Black) which would have been easy enough to splice into. But, the tablet, in reality, has a ribbon cable coming from the battery, not really likely to attach anything to that pigtail without breaking something. So, looks like Lavalink or bust.

Cheapo eBay desktop cradles

Has anyone purchased any of the cheap ($9.99) cradles listed on ebay (http://cgi.ebay.com/For-Sprint-PPC-...m/ws/eBayISAPI.dll?ViewItem&item=290202333980 for example)?
I am not expecting great quality, but I just want to know if the 8925 fits snuggly in there and that when you take it off it's not a two hands operation because the phone is jammed so hard in the cradle that it takes two hands to take it off.
Thanks.
Briefly considered it, but didn't pull the trigger. (I actually had my eye on a different model that allowed you to charge a separate battery at the same time).
My main concern with these docks is that it appears alot of stress can be put on the mini usb port (which is really the only thing connecting the two, and appears to rely on it to keep the standing phone up?) Given the RLOD issues floating about, I personally wouldn't use it...
I bought one. Its one of the squarish ones with an external extra battery charger. It works great! The Kaiser fits snuggly and relatively securely in the cradle. I don't have an extra battery, so I haven't tested the external charger. My only complaint is the LED on the front. It is always on (docked or not) and is INCREDIBLY bright. I turned out the lights in my office, and there was a blue circle projected on the ceiling from this LED! I put a small square of duct tape over the LED, and I can STILL see it! At least it is at a sane brightness level now. Anyway, I recomend this cradle, works great.
i bought two of the little UFO pod looking ones off eBay, one for home and one for the office. They both work great, but being cheap chinese made products, one of them arrived in 2 pieces because whoever assembled it stripped all the screws holding the top and bottom halves together. A little super glue and all was well. I like them and the phone does get supported by the mini usb, but also leans back to the point that it rests against the cradle itself slightly, so im not worried about over stressing the port.
ebay cradles
I have the cradle with "free" 1300Ma battery.
The mount is just a mini usb connector, sometimes is hard to align, unlike the ipaq cradles that have guide slots.
It takes a long time to charge the battery, and you can't tell which battery is being charged.
The blue light in on all the time (power), the other flashes red/green.
It's ok
i have one of those cheapo ones and its fine. initially the charge and battery charge lights were a bit random but now seem to be ok. good thing is i can charge my extended (ie thicker) battery in it as it lays flat in the back

Galaxy Note Inductive Charging Mod

I modified my Galaxy Note to use inductive charging via a palm touchstone / patch.
Just a quick note. Not a whole lot to contribute here, because I largely followed the examples of the Qian Qi. That guy is awesome.
I don't think I voided a warranty, either. Only minimal teardown required (black plastic back, then the speaker section). Never came across a sticker I had to remove....

Notes:
- Buy a good soldering iron. Weller WESD51, set to 610 deg F, with 1/32" long conical tip, with lots of flux and lots of flux remover are the only reason I could do this. I can't stress enough the value of having good temperature control, knowledge of temperature, and so forth. I stumbled around with an "ordinary" soldering iron for a long time, and in hindsite, I can't believe I did so.
- Do not choke on the price. I already had a lot of soldering gear, and I bought $220 more. Spend the money. It's worth it.
- Watch the curious inventor youtube videos on soldering. This guy. Watch everything, several times. http://store.curiousinventor.com/
- You want 30 gauge wire. It's the only thing that just barely can be crammed in. I used the "Kynar" coated type. Buy at least 2 colors.
- as you look at the phone disassembled, with speaker on the bottom left, the +5 pin on the micro usb (MHL) port is the leftmost. I attached a wire to that, and a ground wire to the housing where the port was soldered.
- routed the wires under the speaker, then back, then into a VERY slight indentation into the battery compartment. used a blue "safe open" tool to help shape the wire / crimp ends. Once in the battery compartment, you're golden. Attach the inductive charging coil to the back of the samsung plastic back, add solder to the pads, and attach the wires.
- Attached is a picture with roughly how I routed wires. Red is +5V, Blue is ground. Be sure and double check if my recollection is right where the indentation is into the battery compartment. (that part is by memory).
- dont leave too much slack. it's really hard to get the samsung black pastic panel back on. Mine very slightly bulges.
- be careful where you put the charging sticky patch, because this phone is a little bit bigger than a palm pre. You have to consider if the phone can sit on the charger and "lock in" with the magnets. If you place it too high, it actually can't (in portrait)!
- Qian Qi had a really interesting point: most articles about how Li-ion batteries behave are wrong, and fully discharging the battery drastically reduces the number of cycles you have. So this is actually a very useful mod--whenever you don't use the phone, toss it on the charger.
Thanks for summing it up! Was actually thinking of doing this mod myself. Question: do you have a protective case on your Note? If so - what kind and how badly does it affect the magnetic properties?
No case. Especially because the note is so big, I think it would be unmanageable.
I took the samsung thin plastic back, and placed the Palm PRE (with charging coil still attached) on top of it, on the touchstone -- to figure out proper placement & mark with a pencil. I noticed a buzzing sound, coming from (I think) the induction coil on the palm pre back itself. I suspect if you use a case, this wont work well.
Also, the size/weight/placement of the galaxy note are such that the magnets are just barely strong enough to hold it. One time my phone was near, but off, the charger. I'm not sure if vibration from the phone did that, or my kids
In summary, I'm not sure how well it would work with a case. You might be able to research this on the net; among the 15 or 20 people that have bought a Pre, you might be able to find some info about the effect of a case on inductive charging.
tight squeeze?
im wanting to try this mod i have my touchstone on the way not thank you amazon but it seems like to me that the pad from the pre wouldnt fit under the cover of our phablet =/ could you post pics of the finished product and i think this is the only instance that i have seen someone attempt this with the note and i want to try it i love my note but would love it even more with inductive charging.
I am not the original author but I performed a different Touchstone mod and posted pics here:

Thank you!!!
Thank you so much for your post I have my materials on the way but I hadn't seen a detailed guide for the note other than this one and was worried I would have to solder directly to the usb pins which looked scary lol I did have two questions though would your mod work the same way for the at&t note? Specifically the points where you soldered to the phone and can wireless charging be performed through a case?
Hey, OP here. You may want to hold off just a bit. Mine is exhibiting some issues now. As in, it says "charging" but it doesn't do so wirelessly. The phone will stay "charging" but the battery % never goes up. (It was slow before, but would charge fully over a night).
Charging via USB still works.
It may be something simple; I'm not sure. But I need to crack it open and take a peek, and I haven't had time to do that yet because my phone is functional at the moment.
If nothing has conspicuously changed, there may be something about the design that isn't sustainable. Or maybe my solder joint halfway broke, or one of the wires got smashed enough so that it's partially broken...
I'll write back with my findings. Bug me if I don't
Thanks for the notice I was about to pull the trigger lol tbh I probably shouldn't attempt this I've never done a mod like this before and I'm not exactly a surgeon with a soldering iron lolvthatvbeing being said I'm going to attempt this on an old evo 4g I have before I do surgery on my baby lol plus I'm already familiar with the guts of an evo from screen repairs ill report back with my results

Success it took some doing but I got it I haven't done the mod on my note yet but I did it on my evo last night and it works its rough I haven't cleaned it up yet but I'll post the pics I got this mod from www.goodandevo.net

No prob I just wanted to see if i could do it and if I can do it with little soldering experience I'm sure most could do it I haven't done this mod to my galaxy note though as there is way less room in its a far more complicated mod than the evo because you have to make room for wires in a device samsung made as thin as possible and the way you have to route the wires I feel like the solder joints would just break

For those who want to try this out but still have warrantee just buy a backcover, a micro usb plug and assemble it according to the directions here.If you need the note just take out the usb plug and the back cover and you're good to go.... Or leave it there.....
For those who don't know what pins to use on the usb plug:
Pin: 1 is 5V+ (red)
Pin: 5 is GND (black)
Works like a charm.......

Cool mod! Does it affect the stylus operation though?

yes it affects the stylus sometimes it reacts with delay and sometimes it clicks although only hovers over it

I was not a big stylus user; I can't stand the input lag. I didn't notice a difference, but I always considered the input speed unacceptable. Not sure why there would be any difference, anyway.
My big problem that I've never taken the time to address is that after some time, it's as though I can't pull enough current through the wires to charge. One day I need to crack this open & figure out why.

wonder how fast can a full charge be completed

My evo 4g wont charge

One day i woke up and my evo stopped accepting charge with both usb and wall charger just wondering if 8 can fix it somehow also i am using an alrernative methode of charging it. Ill explain it in case others think there evos are trash sence they cant get it charged. I used a blue lighted charger[single blue dot on the plug] on the part that connects to the phone i cut it from its base, seperating it from the black wire leaving a plug still connected to the wire. I strippes the wires bare(red and black or translusent and black) about an inch and twist them to a fine lone point. From here i take my phone remove the battery and find where the four copper recivers that lune up with the relitive four on the battery. From here i take the black wire that i stripped bare to an inch and thread it through the copper recivers hook like hole on the far left side and do the same with the red on the far right makeing sure they dont touch the other two recivers. Where '^' is a copper reciver and '+' being red wire and '-' being negitive or black it should look like the' - ^ ^ + '. I then connect the battery and the blue light on the charger will light up if done properly i then plug it in and let it charge.

I know my evo usb port broke over time, it got worse and worse. I could use a book to angle the charger up, but that stopped working finally. I now have to use a wall battery charger as I have not found any angle on the charger to get it started.
You could also try flashing a new rom to see if it fixes the issue.
Some suspect the stock cables of being poorly made. Try a different cable.
Also, you can get battery chargers for about $4 (shipped from the U.S.) on Ebay. Much safer than two bare wires. Do that and a spare battery (also cheap) and you should be good.
Look up Hero batteries, they fit and for some reason are half the price, I paid $3 (shipped from the U.S.) for an oem hero battery in good condition.

Same thing happened with mine. To many nights of falling asleep on it with the charger plugged in. Fortunately mine still works but I have to angle it like you. It's not a big deal anymore since I purchased two Gorilla batteries and a wall charger. I use a FTP server to do any transferring of files I need.

Evo charging
Try something as simple as powering down your evo then remove the battery for say a minute or two reinstall battery plug in charger This has worked on my evo when it won't take a charge not sure what it clears out but a good place to start before cutting charge cables or other routes that may not be needed. best of luck.

This happened to me when it would die completely while still on the charger...
Sometimes I would have to leave the battery out for HOURS!!! Sometimes a whole day or it wouldn't start again.

Mine doesn't charge with some chargers for some reason. It'll charge up fine with the HTC units that came with the phone, aside from that it seems like I get a trickle charge with any other. My port is also loose, ahh well. Few more months and the SIII will drop hopefully.
Mine stopped charging through the USB port so I took it back to Sprint about a month ago and they replaced it at no charge. Was surprised that they replaced it after I had it so long (got it on launch day).
My Evo stop charging as well, I took it into Sprint and they ordered a replacement for me. I didn't have insurance so I had to pay $35 bucks. I still thought it was a good deal considering I basically got a new phone and I bought it almost two years ago

[Q] loose charging port

I have seen a few post showing that people are noticing their power port on the phone is loose or wiggles, can those of you with an S4 check to see if this is the case or is the connecting good?

Mine wiggles. I even took it to the store and the demo ones all did it. Funny thing is, it only seems severe with the white cable the phone came with. I have a black micro and it seems very snug. I just might use that.
The white one, when plugged in wiggles back and fourth and up and down. The port itself is a tad loose but when 4 of the demo ones at the store wiggled I had a piece of mind.
It's normal. Some people won't even notice it and will say theirs is fine, when in reality it does wiggle. Charges perfectly fine.
also remember there are clips on the cable itself, those start to loose their 'tightness' as well and can be responsible for the loose feeling. I've recently purchased some monoprice cables and fit very sung, but in about a year or so, this port will loosen up, which is hands down one of the biggest adv over the one, we can replace this port when it does go.

But this is a NEW device how can it already become loose.
my point was simply that it's not always the port, it often times can be the cables. if you have a brand new cable and port, i would expect it to be tight, but if the cable is not known/designed to be tight, it might not be the port. I'm using brand new monoprice cales, not the supplied white one, and i'm finding that while there is a little leeway in the base of the connection (which is a good thing) the cable is well secured in the port, meaning it's strength to pull it out/push it in, that should be your judge of port connection, not the wabble in the base. The wobble in the base is actually a good thing, it's not frequent your phone is on a flat surface while charging, and often times the cord is pulling off the side of a table or counter top, this creates pressure in the port. if you've taken physics you understand the concept of levels and mechanical advantage. by giving it a bit of leeway, it lowers the point of lever, and creating less stress on the internals of the port compared to one that has a very snug fit. the only time i would be concerned about the loose port is when it's becoming easier to pull it in/take it out (like throwing a hot dog down a bowling alley
Mine is very solid

[Q] Better Safe than Sorry

I got a good deal on a refurbished Tegra Note 7 so I quickly snagged it as I wanted a tablet for media consumption, some browsing + gaming! Now I've read all the reviews and came across the infamous ultra flimsy micro-usb port. I'm hoping that the tablet was refurbished because of a faulty port and they put in an awesome one! Anyway, do you guys have any suggestions for me so that I don't break the port like using a particular charger, any specific way to charge it(Wireless Charging without any soldering or other method that requires skills with tools?) or anything, really. Also, in case it does break, I'm guessing inevitably it will, has anyone found a convenient way except sending it to the respective manufacturers?
I just recently got a used one off eBay. The cord that came with it was a very tight fit and I could see how that would eventually break the port. Fortunately my samsung cord slips on the port very easily. And since it's white I marked the top of the cord with black magic marker so I never put it in wrong. So far it's working out great.
There's not much else to do but be extremely careful or go buy a Micro USB Type A cable. The whole problem with the port is that they used the wrong one.
http://www.yogaretnam.com/wp-content/uploads/2012/07/micro_usb_type_a_b.jpg
I never even knew there were two types of Micro USB connectors until I got this thing. I never bothered to get the right cable (and Nvidia didn't bother including the right one... did they even know there were two types?), and thanks to a minor fall while plugged in, I have to plug my cable in slightly crooked to get it to charge right. If I plug it straight in, it will show it's charging but actually drain the battery even if the stupid thing is off!
