[Q] Question/Observation about Heat+Wireless Charging - Nexus 5 Q&A, Help & Troubleshooting

This is something I've noticed after using wireless charging to charge overnight for the past few months. I've been using the Nokia wireless charger, and in the morning the phone is usually warm. It's not hot. I checked temp and it's around 95F which is about how it gets after 5-10 min of browsing. I'm not concerned about the temperature, however I was just curious why I've never observed that with wired charging. I know that wireless charging heats up the phone more than wired charging, but after hitting 100% I thought it would act similar. After picking up the phone in the morning it feels cool when taking it off a wired charger. Granted, I've only used this one wireless charger for overnight charging. I have the nexus wireless charger that I keep in the car. I suppose I can try and see what results I get with that.
Anyway, just curious why you guys think. Again, I'm not overly concerned, but just wondering if the phone treats trickle charge differently when using wired vs. wireless.

Extremely slow charging

Has anyone had a problem with extremely slow charging? I would plug my phone in and wake up 6 hours later and the phone is still not charged. It's even worse now with the extended battery. 7 hours worth of charging and I'm only at 85%. I'm rooted and using the de-bloat rom without the kernel, but it was like this even before the root. Has anyone else encountered this strange issue. I have been using the stock HTC charger.
mine charges in a couple hours using the wall charger and wifi hotspot. In the car or via computer USB, it charges very slowly and if wifi hotspot is on, it loses charger over time.
I typically turn my phone off to charge; speeds things up 2-3 fold.

Mine doesn't even take an hour . Power it off and try it that way and see how long it takes.
damn mine charges super fast compared to my nexus s i had
If you have plug to the computer it might take longer but not 6 hours, on the wall it only takes like an hour or two to be fully charge.
If it's an issue just take it back and get another one.
Yeah I might have to return this phone. Do you think it matters whether I use the cable that came with the phone, or a regular usb cable to charge.

You need to look at the power ratings of the adapters you're using. This behemoth phone can receive 1000ma, while many car and home chargers (like Droid1) are only rated at 500ma. I'm still trying to figure out what the power draw is on the phone when just idling (battery monitor widget is hard to understand), but if the phone draws 250-500ma with regular usage, its going to lose charge plugged into USB (rated at 500ma per port) and running hotspot (drawing closer to 600ma). That's -100ma.
These numbers are guesstimates. I'm not sure if the cable itself can pose limitations, but would suspect that as long as there's no shorts in the wire, it would be able to handle any of the above currents.

yeah i find it impossible to charge the thing on USB, and it takes forever plugged into the wall with the charger it came with.
Had an evo, and it would almost full charge (from the time it said to plug it in, so 15%) in about an hour and a half. The thunderbolt seems to take 3 hours ish for me. I know I can turn the phone off, but since it usually charges over night its not a big deal, I just think it is interesting that it is so different.
yeah I'm one of the folks who charges FAST. It has really surprised me...I actually thought everyone was charging super fast until this thread.

+1 on looking at your adapter. Use the one that comes with the phone or make sure that it's rated at 1000mA/1A or more. I tried a MicroUSB adapter I had lying around that came with a bluetooth headset; turns out it only puts out 200mA, so the phone would take forever to charge on it.

with an output of 200mA I would be amazed if you could get this phone to charge at all, without having a custome kernel and underclocking the processor. If anything I would see it maybe staying same battery percentage.
Overall I feel this phone does charge really slow. It is way slow charging on a computer. I was charging it and just doing some light texting and after 4 hours the battery only went up by like 25%.
I have a second wall charger rated at 1000mAH, and after 30min it went up like 10%. This was with the phone off btw. With it on, but not in use, it went up like 4% over 30min. I'm kind of surprised how long it takes to charge. I've had no problems charging it at night. Plug it in before bed, and its full when I wake up. How does the 1400mAH battery size compare to other phones?
I did a little math too, the battery is a 5.18 W/hr battery. So with a 1AH charge at 5V, you'd expect the phone to charge in 2 hrs if only about 50% of the electricity is getting retained by the battery.
I've noticed that mine takes about 1hr 45ish mins to charge from completly dead. My Droid used to be an hour at the most.
i just checked on the adapter it came with, it's 200 mA...did people get better chargers than me or something? Mine takes forever to charge also...been stuck at 99% for 30 mins
EDIT: nvm, i was looking at input, not output...still isnt moving from 99% to 100% though

@lorijuan1024 im with you man the Nexus S took forever...... To charge
its impossible for me to charge it through the computer, it went up 5% over 3 hours, wasnt on hotspot, sending texts.
Mine charges fine on anything, I am using my old fascinate charger.
Charging speed seems to fluctuate for me... sometimes I get lucky and its fast. Other times, not so much.

Anyone else having wireless charging issues?

Wireless charging seems flaky at best. Sometimes, it works like a champ. Sometimes, my phone will stop charging, start charging, stop charging, start charging, etc. until I get annoyed, pick it up, and put it back on the charger. I left it on the charger overnight and found it at 87% this morning. I don't know if it wasn't charging properly that whole time, or if it got to 100% and then just stopped charging. Any tips on this? Anyone else having similar issues?
FYI - this is the Samsung charging pad and the phone with no case or anything on it.
No issues here. Work flawlessly
I'm also having the issue with wireless charging starting and stopping. My charging pad, however is an ebay qi pad. Seems very position dependent on both of the pads I was using successfully with my S3.
The behavior is that it will start charging, then 10 seconds to a minute later stop. Then start....then stop...
S6
I have the sony charging pad and I've noticed my S6 stops charging when I get any kind of notification...
No issues here
you shall use 2A chargers to be effective.
I do. I have an official Samsung 2A charger with an official Samsung USB cable attached to an official Samsung wireless charger.
I haven't paid attention to it throughout the day, but I did notice that if I place my phone on the wireless charger it seems to charge to 100% and then it will stop charging. I know a few nights ago the samsung puck was green when I fell asleep but in the morning when I woke up I was down to 92%. I will be taking the wireless charger with me to work tomorrow so I will know for sure if it stops charging at 100% or if it does what you are describing.
Both my gf and I bought our Galaxy s6 edge on release day at Bestbuy and with the preorder the wireless chargers we're included free. The past 2 nights both of our phones have had this issue. Mine only charged to 87% yesterday and 93% today. Hers was at 88% yestwrday and 96%today.
I'm curious if the wireless charger takes a much longer time to completely charge the device to 100%.
For me better wireless charger than wire... I think I've better battety life.
With wireless charging I use wire charger included.

iirc thats supposed to happen to prevent overcharging.
Does wireless charge work with OTG plugged in?

Thats makes sense but I've my wireless charger next to be bedside table and I was woken up but the charger plugged in notification sound constancy going off.
It would be really great to turn those sounds off. Also, you have to assume that there's some battery level where it will restart wireless charging, right?

This is what I was hoping for when I said above that I saw it hit 100% and then overnight it drained to 92%. I would hope that if it falls below 97% or so that it would charge again to 100% so it keeps cycling but right now I am not sure if it does it.
I've noticed the exact same problem with mine. I got the free Samsung official wireless charger from Best Buy. The phone charges to 100% every night but when it finishes, usually around 3 or 4 a.m., it just stops charging and doesn't start again. So this means that every day when I wake up my phone has drained to around 90%. This never happened with my Nexus 5 on a generic wireless charger. It always kept it topped up until I remove the phone. This is really annoying.
BTW if you go into the settings menu under battery, you can see exactly when your phone stopped charging.

that sounds like the best reason untill i hear anything more concrete, might try charging tonight direct via the cable and see if it hits 100%
but with no replaceable battery they may have introduced this to prolong the life of the battery.
I totally get not overcharging. But it's got to kick back on at some point. Leaving your phone on a charger overnight should basically guarantee 100% in the morning. Maybe at 97% it could kick back on, or at 100%, it could go into a trickle mode. I'm sure some custom development will come along and fix this problem.
Here's hoping for an update or something through soon. Gonna test a full charge before tonight and see if it actually states it reaches 100%
I'll post what I find.

wireless charging question

I have long ignored wireless charging, because it's so much slower than wired fast-charging. I keep seeing mentions of the Note wireless charging capability, but I'm still unclear on whether wireless is now as fast? Doubt it, but am I wrong? Would especially love a fast wireless charging solution in the car, that was as fast as the fasted wired option. Does that exist yet? Or do I need to check again in 2-3 years?
Wireless charging is not as fast. Note9 also uses adaptive fast charging 2.0. Fast but not as fast as other standards. I would concern myself about fast charging only when needed. I use wireless charging exclusively at night to slow charge my battery. I think Samsung chose adaptive 2.0 to help with longevity of phone because fast charging does not help with longevity of battery. I am still pressuring companies to unseal the batteries. The environment is more important than being able to take a shower with your phone or not having to worry about dropping it in the toilet because you can't wait five minutes.
The appeal of wireless charging is so you didn't have to reach for a power cord to plug in your phone every time you wanted to charge it. I just upgraded to the Note 9 from my Note 4. When I had a new battery in it, wireless charging only took about 20 minutes longer than the cord. As the battery got older, it did seem to take longer with the wireless charging. For me, if I'm just at home, I use wireless charging. If I'm about to go out in the next 30 minutes for a while and the battery power is kinda low, I plug it in to get a fast full charge. Plugging in the phone all the time is a drag. You are missing out on a cool feature while wasting years waiting for something better. I keep a separate power cord next to my wireless charger. That way I can decide if I just want the phone to get charged using wireless, or if I need a fast quick charge with the cord. You aren't just stuck with wireless charging just because you bought one. A flat wireless charger is just $15 on Amazon. It works just as well as the $60 Duo charger from Samsung, although it does offer fast charging. Not worth that kind of money though. Plus it is big and takes up too much space.

I have one. Works well. Got it from Indiegogo, backed a project called the MAGQI X: The Smartest Wireless Car Charger Mount...
It charges faily well but I did find on my Note 8 it was only just holding power as I used GPS...Mind you, that could be caused by the case I had it in, my Note 9 seems to pick up the power pretty quick...
So, can the Note 9 handle the 12W wireless charge or is it limited to 10W? I see the comment above regarding the Duo Dock, but that doesn't necessarily mean that it supports it and I have not been able to find the exact spec on the matter elsewhere to confirm one way or another.

Wireless charging constantly pauses

I just received and started using the RAM mount tough charge with X grip wireless charger that I use for a Samsung Galaxy Note 20 Ultra. https://www.rammount.com/part/RAM-HOL-UN12WB
I use it to attach and use my phone on my wheelchair. The charger is connected to a regular USB port which draws power from the power wheelchair batteries. As I use my phone, the wireless charging constantly and randomly stops working and the phone keeps on popping up that the wireless charging is paused with the light of the charger going red but then several seconds later it will start working again and the light turns green. I don't know if it's related but I have noticed the phone does get hot while charging on this particular charger as I use the phone. I just recently received a notification saying it was paused because the phone got too hot. I also turned off the fast wireless charging setting on my phone. I haven't had the same issue or have the first day it got too hot with other wireless chargers using the same USB connection of the wheelchair and plugged into a regular wall outlet. Do you have any suggestion to fix this issue? Is there a possibility I have a defective unit? If you can't think of a fix, is there a way anybody has figured out how to disable the wireless charging paused and the wireless charging pop-up notifications? It is quite annoying because when it starts charging the notification takes up much of the screen in the center. Thanks in advance.
That is only 10W charger so it can't do quick charge.
But maybe there is defekt in the wireless charger. Also rare names usually is typical China product that isn't well known and usually are poorly made so problems like these may occur

It is actually a quite reputable company that makes lots of phone and tablet mounts. I will contact the company because it sounds like it could be a defective product. I was just seeing if anybody have ideas. It could be an overheating issue. As it charges, the temperature moves anywhere between 96 degrees Fahrenheit + 106 degrees Fahrenheit. Is that a normal temperature range?
Is there a way to get rid of the wireless notification when it is charging and paused? Especially when it starts charging the pop-up is annoying

I just looked up the information for the USB charging port adapter for the wheelchair. It says it can power up to 1.5A at 5V. Would there be an issue if the wireless charger is 10W?

There might be an issue. If the USB port can only supply 7.5W then it will be impossible for the wireless charger to send 10W to the phone. Subtract losses for wireless charging inefficiency and you'd be lucky to see even 5W arrive at the phone. Depending on how good the link is from charger to phone in terms of gap and alignment you might get even less.
It's not just you. Mine has been doing that the last couple weeks too. On an older samsung wireless charger.
Seems like it started after one of the software updates, but can't be positive.
I just installed the android 11 update and am going to see if that fixes it. My wireless charger is at work so can't try it out until tomorrow.
I will say the phone is very noticeably faster after the android 11 update.

General Wireless charging

Wireless charging is awful on this device. No matter what case (or even no case), my phone must often does not charge wirelessly. I've tried multiple chargers. I get the "connected; not charging" message. Sometimes it works, but seems to need to be in the exact spot. Even then, it often stops charging after a while or drains faster than it charges.
Any insight or solution to this?
This is a stock pixel 7 pro, bootloader still locked. Bought from Google store and activated on T-mobile.
What wireless charging pad are you using?
I was having all the same thoughts as you. Had a couple Samsung "fast" wireless chargers. However, bought a new one Costco that's not Samsung and it works as expected. Never have to realign or wake up to a dead phone anymore.
my rooted p7p with tq1a.230205.002
is charging well with wireless pads and wireless powerbanks.
always heating up p7p tho
I don't know why people like using Samsung but I prefer other brands
the backrooms​
My Pixel 7 Pro works fine using this 30w Wireless Charger from Amazon - Nanami 30W Max Wireless Charger
This is the only thing missing from the OnePlus 11 - but I don't care...

A variety that all worked great with my Samsung s20. Ankers, Samsung, and a few generics that worked better. None work well with the pixel 7 pro
I'm using the Belkin 15w charger and it seems to be working well.
I use the wireless charging dock I bought for my OnePlus9 Pro. Never had an issue with charging

In my case, I figured out my wireless charging is unstable if my phone is in any condition where it might get at all warm. The Pixel 7s are just lousy at staying cool, and once the temperature rises to high 30/low 40C (which doesn't take much at all), wireless charging is severely throttled if not completely stopped. So if it's sunny out, I understand my phone won't charge in my car mount. The sun just makes it too hot, and it won't bother (no matter how cool I keep it in my car, direct sunlight on the phone is too much). If it's sitting on my wireless charger and I decide to try and use my phone while it charges, I understand odds are VERY high it will get too hot and stop charging. And if it stops charging because it has overheated, I know now to give up rather than keep readjusting it on the wireless charger, because even if it's not charging, if it's trying, it's still making the phone hotter, which is making it take even longer to cool down and resume charging. So I just take it off and don't bother putting it back on until it's gotten a chance to settle first.
It's finicky and irritating that their flagship has such lousy thermal control, but knowing that my wireless charging issues are linked to my phone's temperature has helped me understand how to keep my phone charged. Those who only charge wirelessly without ever trying to use the phone and only in particularly cool environments may never observe any wireless charging issues at all.

I noticed this too
I find Power saver with less brightness helps, but if it gets hot it's not charging at all
No problems with 2 different wireless chargers with a transparent case.
I measured the power usage with an external device and its mostly the charger uses 14 watts power between 0 and 80%. (don't forget the energy loss with this technology!)
No real overheating. But placing the device correctly affects the power draw a lot.
I agree. It's terrible, no matter what charging pad i use, it always glitchy.
Not to mention, the reverse charging won't work properly either. Plenty of time i need to recharge my buds while travelling to no avail.
I struggled with wireless chargers for P7P too, I tried at least 4 with varying degrees of success but ultimately I just ended up using some of the store credit I got for buying to the phone to get a Pixel Stand 2 and it works great.
I can happily say : MARCH RELEASE FIXED MY WIRELESS CHARGING ISSUE.
