[Q] question about wireless chargers

I am purchasing a Galaxy S5 next week and I am looking at the wireless chargers as that is the main reason I am upgrading my S3 in the first place. I have read that once placed on the charger the screen will read "wireless Charging" What I am wanting to know is if the phone is still on and if my wireless hotspot will continue to work in wireless charge mode?

Hi ! Your S3 can already have wireless charging if u didn't know ^^
Your phone will still be on(screen off ofc), and for hotspot, I'm 99.9% sure it works while charging

I kind of thought the hotspot would still be active, on the other note I had no idea the s3 was wireless charging. does that mean all it needs is a pad to lie it on? Not sure if I understand?

Yes it will. Or at least it does for me, so I don't see any reason it wouldn't for you as well. Your hotspot range may be reduced during wireless charging due to the RF interference, but if you had a strong signal before hand then you should be fine..
.

I've noticed no loss in wifi, hotspot or 3g performance while wireless charging, and the S3 and S5 can both use the same charging pad because they both QI compatible.

~7 dB effective attenuation when wirelessly charging my S5
Inferred from the increased 802.11N PER in an adjacent Asus RT-N66U router.
And consistent with decreased data throughput.
PER calculated from Ethereal capture.
Sample size = 5 x 10^3 packets
PER (packet error rate) is 1-(0.999^N), where N is the number of bits in the data packet
N = 32
NF transmit output = +17 dBm

None of the S5 variants that I have seen will wirelessly charge by simply placing them on a charger. You need to add two things - the charger and a coil. The coil is the part that is inside the phone, a sort of receiver. The coil looks like a thick sticker and you can either buy an optional battery cover from Samsung that has a coil in it.. or add a third party coil to the inside of your existing battery cover. This is in contrast to say a Nexus phone where the coil is not optional - it is already built into all of the Nexus phones.
So it's odd to say that you are upgrading from a S3 to a S5 because of wireless charging.. when both the S3 and S5 need to have the same components added to add wireless charging. You seem to think that the coil is standard on S5's and it isn't.
Note that the optional Samsung wireless battery cover is thicker than the standard battery cover, which means that some cases will no longer fit your phone. And if you add a coil to the inside of the standard S5 battery cover, you need to choose a coil that is thin or you may displace the battery cover and lose the watertight seal.

Thanks for straightening that out for me. Now I understand. Yes I am upgrading from a s3. I knew nothing about wireless charging until recently. Guess I need to get my nose into these boards more often. I am a road warrior and ran into usb port issues on my s3 in Denver a few months ago. I panic because I couldn't charge my phone, so I went to the closest 3rd party phone repair store and they sold me an extra battery and a external charger. That worked great but the fact that I had to swap batteries 2-3 times a day, left my phone without a case, and you know what happened next. So since my upgrade is tomorrow, it's time for a new phone and I am excited for the s5 anyway. Thanks again for the help,:good:

No doubt you will love the S5. It's a significant upgrade from the S3, which was already a very good phone in it's own right. Enjoy

Battery Temp Sensor Issue after replacing battery

I replaced battery and USB Port on two Nexus 4 phones. Now the battery temperature perpetually reads 28.1C (give or take 0.1).
Battery and USB Port were ordered from FixEZ.com
USB Port replacement fixed original charging issues on both phones, but now have new issues. The new issue is that the phone struggles to top off the battery and make turn off unexpectedly at low battery with red LED.
My best guess is that if the battery perpetually reports 28.1C, then the phone can't compensate for battery temperature during charge/discharge.
I can feel the battery warm up during a charge from low battery (yes the battery, not the CPU) , but the highest I have ever seen the phone report the battery temp is 28.3C.
Assuming that the batteries were counterfeit/defective, I ordered 2 more replacements from FixEZ and started RMA for the first two. The two new batteries were marked differently (different source). I replaced the battery on one of the phones and get the same battery temp value issue.
So now, I'm at a loss what to check/do next. Is the battery temp sensor part of the battery? Or is it somewhere inside the phone and it's supposed to touch the battery?
Searching on battery temp issue tends to yield people with broken temp sensors (too cold). I do wonder if my issue is more common than people realize since I see a lot of nightmare stories about poor performance after changing the battery.

Also wanted to add, that my phones are running stock Android 5.1.1, never been rooted, and I did a factory reset on them to see if that would help.

Hmm, instead of a factory reset, can you try flashing the latest stock image through fastboot?

Try pushing the battery connector really hard with the phone running and a battery monitor like Ampere running. Obviously you run the risk of cracking the screen, so you need to be very firm, and gradual with pressure. If Ampere suddenly changes from cold to charging, it's a sensor issue on the motherboard.

The constant temperature could be an indication that the batteries are not oem batteries even though the labels make them look like real original oem batteries.

I had this problem, and I swapped 3 batteries or various conditions and years of manufacture (one obviously non OEM). All 3 wouldn't charge unless I put an extremely high amount of localised pressure on the charge connector, thereby making a circuit with the sensor on the motherboard. Why they didn't put the thermal sensor on the battery is beyond me. Basically I've got a knackered motherboard, at least as far as the thermal sensor is concerned.

I have this problem with the last two replacement I bought, but if I put the original that came with the phone (already damage but works if I plug the charger), the battery report an accurate temperature.. my guess is that the sensor uses a component in the battery, but because the new ones are possible fake the didn't add to the battery due cost saving... Also read that the fakes one used to have a resistor to simulate the sensor.. I will try to open the batteries to compare..

Zenfone 2 Deluxe Edition

I have a weird story I thought I would share and I wondered if anyone else has seen anything similar. Recently I ordered the Deluxe Edition 128GB / 4GB Zenfone 2 from Amazon. When it arrived I thought nothing out of the ordinary, until I had them send me a replacement for it. The original one I received was sealed, but there was no second battery cover, no USB cable, no headset and no English owners guide and warranty card and no extra serial number stickers. What was in the box was the phone, a 220V charger with an export adapter and a a user guide in french. I put my Cricket SIM card in and immediately only got H+ data, no LTE or 4G at all. I charged the battery and it drained faster than anything I have ever owned in my life. After a week of trying tweaks and multiple SIM Cards and still not getting any LTE, I decided to order a replacement. After I set up the return I called Amazon and told them to please make sure they shipped me the US VERSION of this phone. I received the replacement two days ago and it is like night and day. Both battery covers, 110v charger, USB cable, headset, English user guides and stickers for warranty. Best of all I have not lost LTE signal since installing my SIM card and my batter life rocks. After a first full charge, I was online with about 50 minutes of screen on time and lost 3% battery. The original one I would have dropped 30% or more in that amount of time. So I'm wondering now what Amazon sent me in the first place. The serial number on the box has a second serial number stuck over the original. The carbon fiber (look) battery cover on the original is a cheesy sticker and on the new one it's more of a composite. Does ASUS ship the international version (WW) like this with things missing and a crappy carbon fiber sticker on a stock battery cover? Or did I end up with some fake device? Before I return the old one I will take side by sides and post them here. Either way I am glad I had a replacement sent rather than give on this device because the replacement is amazing. I rooted it and removed the crapware and have zero issues at all.

Just search for "zenfone supercopy" there you find some replica phones...
Possible that some reseller sells it as original and Amazon just send it to you for faster delivery....
Glad that your now got an original zf2.

Magnetic phone mount

Do you guys thing that a magnetic phone mount will affect the s10 due to the new wireless charging feature?

pitaka is making a case for the S10+ and S10 that won't interfere with wireless charging...

Should not affect phone as long as you dont place the metal plate in center of back of phone. Place closer to the bottom and stick it to the case not the phone. It's a pain in the a** to peel off phone. 20 bucks at walmart.

There are magnetic wireless mounts available, but my experience had been mixed. I just updated my review on Amazon of this device, from 5 stars to 2 (awaiting approval of the update). It was great for the most part, but the big issue for me was the inconsistent charge rate vs heating whilst charging. Sometimes it charged well, without heating much. Other times it was the opposite. I think performance was heavily influenced by exact positioning and the exact position needed was not repeatable every time.

I'm waiting for word on whether or not this Scosche mount is compatible with the S10+.
https://www.scosche.com/collections/wireless-phone-chargers#/page/1
I have a similar charging dash mount from Mophie installed in my car right now that has worked well with my Galaxy S8+ as a mount, but I never ran the wires for the charging part of it. I have Mophie's desktop version as well that I have on my nightstand for nightly charging and it works well to charge the phone through the Mophie magnetic case, so it is possible to have magnetic mounting and wireless charging in one unit. Unfortunately, Mophie canceled their ChargeForce line a while back so I won't be able to get a compatible case for my S10+ and I'll have to switch to the Scosche or some similar system instead.

There should be a Nillkin Magic Case released this month, with four built in magnets/plates to match the Nillkin charger. It looks like this design would avoid or reduce the problems of misalignment and/or overheating as it keeps thing well clear of the induction coil. S9+ version below. See Q&A regarding S10+.

On a side note, my S10+ 1TB should arrive tomorrow, direct from Samsung.

Galaxy S7 Edge won't charge/boot/anything

Hello all,
this is a rather strange thing that recently happened: my dad's galaxy S7 edge which has been working completely flawless the last few years recently decided to just turn it self off. He handed it to me saying it was working fine last night and trying to use it next day absolutely nothing happens anymore.
I tried to charge via USB with Samsung charger, wireless charger from Anker in case the USB port is defective, and different key combos to restart etc. On PC nothing is detected either..
Could a faulty USB charger have killed the device? When plugging it in, there is absolutely no sign of life - you can hear a faint "buzzing" but no indicator lights etc..
Does anyone have any tips? It would be really appreciated!

Battery or port pcb failure. Maybe both.
Replace battery as it's long overdue.
Once an Li reaches 80% of its original capacity it's reached the end of its usable lifespan.
It's degraded at that point. Degraded Li's are more likely to fail. Any swelling is a failure; replace immediately if observed.
Replace battery and go from there...

Thanks @blackhawk for the tips and insight - I will try to replace the battery!

On a heavily used device the battery lifespan is typically 1-3 years.
I plan to replace my N10+ device's battery about every year, routine maintenance.
A failed Li can do a lot of damage. It rests on the display... which is somewhat fragile.
Get a new rear cover seal when replacing the battery so it retains its water resistance. On AMOLED (NOT LCD displays!!!) displays anhydrous isopropyl alcohol can be used to help loosen the double sides tape on the rear cover and battery if you do it yourself.
Controlled heat is used to help loosen the rear cover on most of these phones. Many shops will replace the battery for a low price as well.

Pretty amazing stuff right here. My S7 Edge did the exact same thing last night.
Think Samsung hit the kill switch.

I'm writing this message from my dad's s7 edge which has kinda the same problem but it's still usable. It shuts down suddenly (even with battery full 100%) and the only way to turn it on is plugging it to the charger, otherwise no sign of life.

I believe, most of this case was caused by power IC, my s7 edge was suddenly died last night too. You can see on this thread and tutorial.

Yeah, i want to try this too, but i think it cost too much money, not worth for me. And also i dont trust to much for 3rd party repair on here except samsung service center.
But u can give it a try. Hope it works.
