Battery question

So for the last 2 days before work, I would charge my phone completly to 100%. I work at 4am and it would be 99%....ok forward ahead 2-3 hours, ill check my phone and its at 20%. I've already check tsk manger both days but I only leave panda firewall running and alarming!
Is this defective battery? Or something else? Any ideas.

Do you have an extra battery to test with or just the one? If you have two batteries, it would be easier to diagnose whether the first battery is defective based on how fast the second battery drains. It might be worth borrowing a friends or buying one on amazon. You can get the OEM battery for relatively cheap nowadays (<$20)

Also depending on how long you have had your phone for you can call T-Mobile up and complain. I did this and got a free 2nd battery. Just tell them you have already gone through troubleshooting steps by turning off gps, bluetooth, wifi, 3g, and lowered the screen brightness. Even if you are over your allowed time I'm sure if you talk right you still might get a free battery, my friend did to.

Yeah, I did this too, but that was a while ago (November or December) when it seems that T-Mobile was handing out batteries like candy to pacify all the people that were upset with battery life. I didn't know if people were still succeeding in getting a battery for free, but that is definitely worth a try first.

lol. Yea they was just handing them out. My friend got one just the other month so its seems they are still trying to satisfy the customer.

Alright I'm probably just gonna go into tmobile cause it would be easier probably. And I've had my phone on for 10 minutes now for break, went from 17% down to less then 5% so.... this is irritating me....DAMN TMOBILE! Even if it isn't there fault I still want to blame them!

i bought my battery for 8 bucks =x i didnt feel like goig thru tmobiles battery crap

You might have to call them up. I don't think they will do it in the store, but again if you know how to talk anything can happen.

I'm not sure if it makes a difference or not, but when I was running Cyanogens roms above 3.6.5 I would get horrible battery readings. I'd reboot and it would says something different.

I believe its a known bug in Cupcake builds about battery readings. Cyanogen did post up a link to Android's official bug tracker but I can't remember the link by memory.
Also try calibrating your battery too and use a program like Watts to track your battery usage over time.
Also using the Open Overclocker widget is amazing, you can set the Screen Off CPU frequency, forcing the CPU to scale down when idle. I'm not 100% sure if Cyanogen's ROM does this on default or not though but I know it does do CPU scaling.

Posting here since its battery related .. ever since the upgrade to crc1 my battery charges extremely slow .. like it wont go to 100 percent in 8hrs .. but when I restart it at like 80% it will show 100, but if i leave it there long enough im sure it will keep climing slowly in percentage. Anyone else having problems like this?

Yes, it's a known bug.
Fully charge your battery then do the following.
su
rm /data/system/batterystats.bin
The battery reading will be more accurate.

Alot were right, nothing can be done in store. They pretty much shooed me away and said to call 611. Did. Told me to call HTC. Can't cause there closed lol. Anyways im going to try what Prettyboy said, but I'm turn the phone off I think to charge it fully. No extra battery though =/ They said I would have to provide a CC to get them to send an extra battery and then send the old one back.

thanks for this. but what does it exactly do??

It deletes the old battery stats file and Android creates a new one, which would be more accurately calibrated. Think of it like a battery stats reset.

[Q] Optimus 2x-Battery drains 30-40% over night

Sorry for my bad use of English;
I got my lg optimus 2x 1 month ago and i noticed a huge battery drain.I was thinking that it will work fine after 6-7 full cycles.I saw a thread in which a guy that after doing a factory reset(he had the same problems as i have) the battery will work normally.
I did that but it didn't work for me. Is this the solution?Did I do it right?Do i have to buy a new battery? I have rooted my phone yesterday so I was thinking is this a software issue? I have lg official 2.3.4 ROM. DO i need another ROM?
please.
Help me guys.
Thank you!!!

Do you leave data usage on during the night? Are your apps allowed to synch automatically? Try using airplane mode during the night (that's what I do... I don't normally get calls or messages during the night )

I don't leave wifi ,background data or 3g on,if i leave it charged at 100% at the time i got to bed,the next day when i get back from school,without using the phone my battery level is around 40%.

Using a live wallpaper? The factory reset only works because it stops the application/rogue setting from being there.
If you get 'Battery Monitor' you will be able to see what is draining you battery, and any 'wake-locks' or 'partial-wakelocks' that are stopping the phone from going into sleep mode.

look at the battery usage indicator and post a screenshot of it. Maybe the problem can be isolated.

Now i am on cyanogenmod 7.1. I have charged the battery to,but after 5-6 hours of standby and 10 minutes of games it has reached 28%
Please help me. Is it a way out of this? Do i need a new battery? Does the phone eat more power than what it is intendet to?

Jesus christ, at one point it almost seems to go backwards!!!
I never had anything like that, I can tell you that!

I have the same problem but my issue is that after charging for whole night and keeping the phone in switch off still my battery drains to zero %, then i gave my phone to service center they kept it 2 days and told me that the phone mother board has some issue need to replace it, my advise give back to service center and look what they say.

Yes that's why I did a general test drive for two weeks on my phone before starting flashing and rooting and what not. Unfortunately our friend here has already flashed CM7 on it.
Unless he's able to restore stock software I'm affraid he won't be covered by warranty...

If he uses NVFlash he will be able to get it back to stock

Its easy to put back stock firmware if he knows wchich one he had, btw usually there is one backup on your sd card, check for it.

Can i test them? cause i bought the phone from other town and i will have to pay for shipping.(and i want to be sure if something is broken)

Try to flash a cm9 rom. It saves a lot of juices. For 2.3.X. The battery drians is really terrible

[BATTERY IMPROVEMENT] Works every time half the time :)

DISCLAIMER AS PER USUAL: YOU DO IT AT YOUR OWN RISK.
Although procedure itself is simple enough, but as alway, anything involving flashing, especially firmware has it's risks.
Oki doki. Time to come out in the open
Prelude. I was hard pressed to get 4h screen on time in 10-12h off charger. Then i screwed something up (irrelevant ) and had to reflash stock images.
Now my next findings are sure to attract so flaming from more experienced users that will say "it's placebo", "it doesn't work like that" etc. While I don't have screenies to confirm pre flash stats, i have gathered a few post flash stats. Here we go.
Some cycles are missing, since i either accidently deleted screenies or forgot to take them. But that should give you a general idea. WiFi used mainly, apart from last cycle, where 12 were on data only and the rest was while connected to wifi and reading a book in fbreader.

And this is ROM/KERNEL i used before and after flashing images. Note, kernel has been updates since, but it didn't make much difference.
So for me it's fairly conclusive, reflashing stock images has GREATLY improved my battery life. I had a few chats and we came to a conclusion that it is possible that at the factory device has simply not been flashed "properly", mass flashing differs from your usual .img flashing normally.
What you think...Well, it's up to you for decide. I know few more people who've done the same, and while their improvement is not as drastic as mine, it is still an improvement.
Please vote AFTER you try it, and after min of 2 cycles.
How to in post no2

Simply follow this great guide by efrant. Keep in mind it will wipe your storage, so backup all the pics and other stuff.
Before you do it, take below quote into consideration if you use google wallet.
dacho said:
Oh yes, you have to reset Google wallet before you flash it. You would log into Google wallet then settings and click reset wallet. I remember this from galaxy nexus days.

efrants guide
People who are more experienced will know how to cut corners If you don't know what you are doing, I suggest you follow efrants guide to the letter. This way you'll learn a fair bit too.
Same process for every images version. Also, I ALWAYS do it for any images update, since I'm not a believer in patching. I might be wrong, but hey, it works for me. So my personal recomendation would be to redo this after every new OTA.
So:
1. Backup your "SD" contents.
2. Flash ALL stock images as per efrants guide (or any other way if you know how to)
3. You are most likely to get stuck on boot. Hold power button, shut down, reboot into recovery. Once you see broken droid hold power button and tap +vol. Once in recovery do factory reset. If you don't get stuck on boot, still do it.
4. Boot on stock. It's a good idea to transfer your rom and kernel onto sd now since you can't mount sd in recovery.
5. Reboot into bootloader and proceed to push recovery and then flash your previous setup (ROM/KERNEL)/
How to push recovery.
Code:
fastboot flash recovery recovery-image-name.img
I will not tolerate any flaming, just report if it worked for you or it didn't. If you want to stir some **** you better go elsewhere. Chit chat related to the topic is approved and appreciated

All on auto, the only two things i have disabled is gnow and location reporting (which is primarily used for gnow anyway) and had that disabled from day one. The rest of the settings are irrelevant, since they are the same from before i reflashed stock.

Interesting, be good to see what others report.
If i hear a few good reports, i might take the plunge next week.
Edit: might just be Rasbean jelly giving you good battery life!

Cool, I'll give it a try and see what it does!
I'm struggling to get +4 hours of battery life ATM, so let's hope this helps.

It's not. Wait till some Americans who done the same thing wake up
There are about 4-5 more people who report the same, that's why i decided to share. Had to make sure first that it's not a fluke.

Re: [BATTERY IMPROVEMENT] Works 100% so far.
The thing that's helping battery life here isn't the reflash, it's the factory reset that happened when you did it.

I would tend to agree. But which would be the cause, removed culprit user installed app(s) or something not set as intended from factory as a result of mass flash/ reset etc at factory? Or both?
Maybe even a difference between OTA updating new units after setup or before?
Would be easy to test the theory by just doing a factory reset without re-flashing and see if it makes a difference.

I did think of that. Thing is flashing ROM fresh IS factory reset. Factory reset doesn't do more than delete all the data and maybe reflash /system. So i disagree with you here Rusty. Think about it. I took my time to carefully evaluate changes, and you might know from my time in Sensation forum that I do look into things before posting it.

See above.
Also, apps have nothing to do with it, since my (and other people) setup is identical to what it was before doing that.
And thanks to the person voting NO. I guess following simple request is too difficult.
If you guys are sceptical, do it before you do next fresh install since you don't lose anything and report back.

I can vouch for this experiment that we somehow agreed to without even hesitating lol.
Personally, i manually installed EVERYTHING. no nandroid or titanium back up. Before i would get roughly 9hr phone usage with 2.5-3 hrs battery. After going through this i now get 13-14hrs phone usage with 4-4.5 screen on. I know that's normal for some but compared to what i had before, is an improvement. This was just in the first cycle. I'm on my second and wool report back when I'm done

As it stands i can hit 5 n half hours with round a day standby.
Would it be worth doing?

Not sure. But someone already had very decent battery life and extended it by another 0.5-1h screen on. I guess you wouldn't lose anything if you tried. Just a half an hour of setting things up.

Dont want to say anything but on screenshoots there is practically no apps other than browser or taptalk, play a game, watch a clip on YT, listen to some music ohh and switch off WiFi. Phone is to be used outside where you dont have a WiFi, At home I have my Laptop that is far much better than than a phone to read stuff, and XBox that is far much better for gaming....
I could probably pull 8h screen if I switch everything off sans WiFi and just have web browser opened on one page.
Ohh And I'm on stock since day 1 + had to reflash image due to kernel net being compatibile with screen sensitivity driver .... No changes, What you have on images wont repeat itself outdoors.
Look at that screen where you dont have WiFi on. Your usage dropped by 8hrs screen time by 1hr and still no phonecalls, txt, nothing really.... just chrome
I get 3hrs 30min screen + 17hrs usage with music in bacground, quick game + and reading, no reception for about 8hrs or if there is any its 1bar....(and that drains the battery)

Ok. I think I have to explain something. This is absolutely not about how or what for phone is used. I used it in the same way before I flashed images.
Concentrate on the MAIN thing. Same usage, same rom and kernel, same settings, same apps. The only difference is battery life after flashing stock images files. Immediately.

What kind of battery life are you getting?

Hey everyone,
I was checking out the battery stats thread over at the m7ul forum, and I was blown away. People were getting 5+ hours screen time, no problem. Obviously, we can't reproduce their setups; our phones aren't compatible with their ROMs.
So, I thought this thread may come in handy for those of us struggling with battery life, and would like to know what kinds of numbers can be achieved. Post your battery stats here along with your setup. Include ROM, kernel, tuning, services, etc. please!
I know the Sprint M7 is kind of a dying community, but hopefully we'll get a lot of participants.

*ahem*
Wow guys don't all post at once.
Anyway, I guess I'll just share mine to get you started.
As you can see, my battery life sucks. Not sure why, because I'm running SD 9 with Kangaroo, and I installed Amplify to reduce the Google Play Services Wakelocks. Also, power saver is on 24x7. If anyone has a recommended setup, that would be great. thanks!

install greenify this will help you significantly increase your battery life https://play.google.com/store/apps/details?id=com.oasisfeng.greenify&hl=en

The sound of silence...
Yeah, hopping place ya got here. LOL. I've ROM hopped all over the place, tuned and tried apps, prayed to the dark lords of battery power, all to no avail. The M7's battery life simply stinks. But, it's a supercomputer in your pocket, so I kinda have to think that's fairly amazing. I use power saver mode ALL the time, never have a need to crank it up, I turn my brightness down to the first bar on the quick toggle when I use it and the lowest setting for just glancing and messages, Beats off, NFC off, any radio I'm not using off, GPS off and in battery saving mode. I stream via Bluetooth for probably five solid hours at work and I can make it all day with some texting and make it home, so I can't complain. But, if I'm streaming, talking, surfing, and such, I'm glad I carry my charger everywhere I go.

Well you can't objectively say it's battery life "stinks" because there are definitely people out there getting absolutely incredible numbers in the int'l forum. I just wanted a Sprint specific thread so that we could replicate the setups of people having great success.

That's actually the reason I created this thread. I want to see if there are any Sprint users who can actually get that kind of battery life. So far, it seems that they can't.
I would hate for that to be true, but I've never seen a Sprint phone get those insane numbers. So, it's possible that Sprint's network is a battery hog. But we can't conclude that unless absolutely nobody posts a good setup.

There doesn't seem to be a lot of us left, unfortunately. Must of the guys I knew when this thing was hot jumped to the M8 when it came out due to the problems this phone has. There's not alot of devs out there making ROMs either, though in HTC's defense, Sense 6 was so awesome there wasn't a huge need to go crazy. The one thing that has always been said though, is poor battery life. I'm on SkyDragon v 10 now with nagging wife kernel and I'm not too unhappy, I can post my stats for fun tomorrow. But, do us unstock guys count in your test?

Yep, anyone who has a sprint htc one can post their stats and setup here. Im running the same thing as you. Hopefully after the settling i get something out of this.
Honestly, Im just desperate to find out if m7sprs can get the same battery life as those insane gsms.

OK @#$% this, I'm out.
Ugghhhhhhhhh why. I used to have TMo, was happy with it, got caught into sprint with gimmicks. I hate my life.
OK it's not that serious, but why is this?
8/5 means 60% EXTRA battery life. That would explain how the people in the international forums get such insane numbers.
So, what's the best we can do with our measly Sprint phones?

Setup and screen shot would be nice, though that's a far cry from the 5 hours in the int'l thread .

I'll be switching to T-Mobile when m9 comes out. Mainly because of the sprint "wait now" network. Have been wanting to switch for years but figured I would give them a chance to fix it.

The m7 on sprint has bad battery life. If all I do is browse the internet on WiFi and text I can average 4 hrs SoT but by then my phone is already about die. This is only on sense sadly I get worse SoT on AOSP

I started a thread on this, but I'll guess I'll ask here too.
What percent of your battery usage goes to Android System? According to GSam. I've noticed that the GSM guys have app usage in the high 20s or mid 30s. Mine is in the mid 50s. The Android System battery drain and kernel wakelocks are the issue here.

From what I've heard, poor signal on your sprint phone decreases your battery life. My average is around 2 hours OST within maybe 13 hours of use? I gave up on trying to make this thing last more than a day

Note 9 - S10 Official Samsung fast wireless charger

Hi there!
I would wanna know why is that my 2 phones (S10, Note9) behaving the same exact way on 2 different Samsung fast chargers - Wireless Charger Duo and Wireless Charger Convertible.
Whenever I try to charge, after like 5 mins, the charging rate drops from 800-840mA to 0-200mA, and it takes around 4-5 hours to fully charge. I tried different official samsung bricks and cables (the one that comes with phone, one that comes with the duo, one that I bought seperately as adaptive fast charger brick etc), ALSO third party bricks and cables, no change whatsoever, behaves the same way.
The phones reach around 38 Celsius the first time when it charges with 800mA, then drops down to 36 Celsius with 0-200mA.
I'm guessing its the heat sensor in either the charger or the phone, but it's ridiculous...I have an ambient temp of around 25-28 celsius since it's summer, but even a 40 celsius on the phone or the charger shouldn't be a problem in my opinion...(PC cpu-s can operate on 60-70 celsius nonstop without even crashing)
Thanks for reading

samsung charging cables are trash.
for me if phone is under direct sunlight at an ambient 30c it will notify me of overheating and stop charging.

Well sorry, but that's obvious, the outer parts of the phone (aluminium and plastic) can get around, I'd guess, 80 celsius in summer in direct sunlight at midday...
I'm obviously not trying to wirelessly charge my phone in direct sunlight, and I advise you the same so thanks for that piece of information...

jd14771 said:
Do you have a case on either phone by chance? since were pointing out the obvious here lol.
Click to expand...
Click to collapse
Of course I do, but that actually doesnt affect it, tried without the cases...
I really think it's the "heating", but the real interesting thing is that I think before the june patch, it didn't matter how hot it got, it just charged with full throttle until about 90%, the dropped to half (500mA-600mA)...I only experienced it after that update...
So noone has a solution I guess...is there any way to overwrite that sensor coding to 39 degrees?

jd14771 said:
Having a thick case can absolutely effect wireless charging, so that's why I asked.
Now you say that it's been since the June patch that it's been acting like this, and Samsung could have very well limited wireless charging under heat.
Due to the harsh reality that is the note 7, these seem to be sensible, required limits to charging. I would not help in changing that hard limit on battery temp current limiting, nor do I suggest anyone else for it's a safety risk.
Is fast charging on? (Assuming it is)
Turn of fast charging and see if the charge temps allow for uninterrupted charging.
Click to expand...
Click to collapse
Well I just made a small test, seems like it only fluctuates a very small amount fast wireless turned off - 380-440mA, and the hottest it gets is 35 celsius degrees.
It really seems to me that when temps hit 38celsius (I dont know which temp sensor is that ,I know its not the cpu part, it's the one shows in apps like Ampere), it just almost disconnects the charging, which is interesting, if it gets just around 38c with 840mA, it just should lower the amp input a bit, like 700mA (somehow, I don't really know how it works, maybe it's either fast or normal charge, not like an adjustable value).
Maybe someone from Samsung team will read this or similar, and make it work
And yes, I do remember the S7 misery and yeah of course, especially during summer, it must be a concern (probably that's why they included this in June patch)
But then again...I bought a topnotch phone, official fast charger, and a few degrees warmer, makes it charge 0-200mA... which is less the half of normal wireless charging

jd14771 said:
You bought a top notch phone, do you want a top notch fire started instead? Lol
I can understand how frustrating it would be to not be able to wireless charge at all like in your situation.
So did turning off fast charging work for you?
Click to expand...
Click to collapse
Come on, it wouldn't start a fire, like I said, it wasn't like this before the june patch (maybe may), I actually did measurements in between fast wired, fast wireless chargings, official and unofficial brands to see if I would need to buy the samsung stuff for 500% that does the same as an offbrand charger, and actually yes, official wireless chargers for samsung do charge the phone around 10-15% faster, BUT I also looked at temps, during springtime, it was well above 39 celsius for the most part of the charging time(it just kept charging full throttle)...
And again, yeah, turning off fast wireless charging goes flawlessly.
Also, did a small test again, wired fast charge, around 1100mA, phone gets around 39-40celsius, yet that keeps on going, no "charging-throttle"...it must be something to do with the parameters and values added in the wireless coding.

I'd post on the samsung forums instead of xda if you really want actual visibly on Samsung's part. dont know why people continue to report issues and expect support from xda when issues as these are clearly something to bring up to the phone company.( screen issues, camera issues etc, all are reported on xda and i suspect only a small amount actualy post about it on samsung forums)
also did you check if fast WIRED charging also has the same issues/behavior?
if so, you know its not related to the type of charging but something newly implemented.

jd14771 said:
Battery degredation by heat is a real problem for lithium. And the fire risk comes from the fact that they can create their own oxygen and putting them out is near impossible unless you have the proper dousing chemicals.
Wireless charging is know for producing excess heat..
Fast charging is know for producing excess heat...
Put them together and you have a hot phone. It sounds like Samsung patched a flaw in the charging system that can lead 5o battery issues over charge cycles.
On one hand The only way to really test this is for you to flash your phone to an earlier OS VERSION and see if this is in fact the case.
On the other hand at least you know you can turn of fast charging in order to produce stable wireless charging currents. I

I would have flashed an earlier, if it was possible, you can't downgrade official firmware since about a year ago, maybe even more. How come you seem to want to show you know a lot, you dont know this?
Once again, I'm sorry, but it seems to me you only wrote here to argue with someone, look at my and your first post.....
You didn't help, just tried to show (for any reason) inferiority by arguing with literally everything I stated.
Now I dont care for that...
Are you a Samsung employee? I know a lot of the software engineers from Samsung and from Google are here to learn, experiment with mods, features, roms etc.
Main point I already made, in an ambient temp of 27 degrees, the 100 dollar fast wireless charger takes 5 hours to charge, which is ridiculous value, and you cant state any reasoning for this, since a few months ago it worked as it should.

People come here for the reason I stated above...a whole lot of software engineers working for eg. Samsung learns a lot here, most of the implemented stuff year by year in official firmwares first appeared on xda as a mod, or as a part of the rom, so if I want to overcome a problem, I'd rather get info from here than from a lowlevel technician/communicator from samsung....also, most of the time, they reply with a "Have you tried pulling out and plugging in? Yes? Then turn off then on, youre welcome!", since they won't acknowledge on official forums what are the flaws in their products, so no solving either...

i get your point and its a valid one. but id still copy paste your post over there. if more people chime in on their site and creates a stir, maybe it will get things going.

jd14771 said:
This in incorrect. Completely incorrect. For both the Exynos and the Snapdragon model. You never stated what version phone you have.
I have the US snapgradon note 9, and i can upgrade and downgrade to ANY available OS version.
For the Exynos variant, you can downgrade so long as the version you are downgrading too has a bootloader version that is the same version. If you are on the current OS version from 7/10, then you can not downgrade. But if you were on Pie 6/03 you could have downgraded all the way to oreo update from 10/11/18.
For why you want to call me out is understandable. im not telling you what you want to hear.
That is not even close to the truth. for anyone who looks all i asked was if you had a case or not- because a thick case will limit or stop wireless charging all together. All you are showing is your lack of understanding or patience because i have not fixed YOUR problem. i find your tone insulting and i hope you can fix this on your own from here on out as i am done trying to offer my help for free. you are the one being rude.
I have already stated two reasons for this. you just have not accepted them. that is fine.
also, i reported your post, so in the future i would try to keep your banter and insults to 0.

You cannot downgrade because the bootloader gets updated...you actually ran into some sort of "self-oximoron"
I call out anyone whom is arguing with me for no reason, don't need that sorry, I've grown up
Why, what do I want to hear? I tell you, maybe someone knows that there is a certain combination of settings/apps that casues this, happened some similar stuff before in smartphone history....I've been using custom roms/mods since 2012, seen/experienced some weird stuff
All you asked was what case I use? Come on..... everything is written here - as long as you won't delete your responses, everyone can see you did not try to help
Done trying to offer help for free? What if I pay? come on man, you sound ridiculous You did not help - otherwise, please, quote your solution to my problem
Also, you replied here, I did not ask for YOUR specific help, I asked a community. Do you know where you are?
Report me all day, haven't written anything offensive...you probably never looked up what offensive means by either law or forums rules...
Also, some literature....
When you write "I would...", its like writing "If I were you, I would do this and that". "I would...your banter..." doesn't make sense.
Have a nice one, thanks for telling me to not use thick cases when I'm wirelessly charging

jd14771 said:
First off, you never specified what model you have, and still have not.
Second, as you can see below, the BOOTLOADER is currently on V3 for the N960F, but only the last update is V3. If you are on V2 you can absolutely downgrade all the way back to Oero from 2018.
And if you have the american Snapdragon model, there has not been a BOOTLOADER update so you can flash any version you please.
So i have no idea why you keep saying that the bootloader was upgraded over a year ago and nobody can downgrade. not sure where you go that misinformation, but i am clarifying for any poor souls reading through this to see the truth.
feel free to quote what i said that was rude. You can't delete posts, and i have not changed any of mine besides spelling typos. Mods will confirm this when they check this since i reported your misconduct.

Couldn't be bothered to read through the arguing (you guys should really grow up) but thought I'd chime in with my testing results, I check the power my Ravpower wireless charger is using so will be different to however you're getting your figures. I'm seeing 9V 1A until it hits 38C and then it drops to 9V 0.5A and then it jumps back up to 9V 1A after the temp drops down to 36C. I have a USB desk fan that I usually point at the phone when wireless charging and that keeps the phone within a few degrees of ambient.
My phone is a N960F running the July firmware.
