Nexus 4 4.3 not charging when overheated - Nexus 4 Q&A, Help & Troubleshooting

As the title says. It stops charging.
If I press *#*#4636#*#* it shows ac connected but not charging.
This started on 4.3. Never saw this on 4.2.2

It's probably a safety net feature. To avoid complete meltdown. Charging heats up the phone too.

Yes it might be but it is really weird cause when it stops charging, it doesn't resume once the phone has cooled down. You have to unplug and replug.
Which isn't very helpful.
Btw totally stock.

That's happened to me when play in summer and just use the fan. Checking the cpu temp shouldn't clock past 50 degrees or it gets pretty bad. I usually just place it in the fan, then on the air conditioner for a minute or two and usually keep the cpu status app open to watch the drop in temperature. Atleast Nexus keeps this safety throttle, S4 would probably give you a nice bacon house.

I think is not CUP related but battery related. I am trying to upload 2 pics but for some reason upload is not working.

Well if the cpu heats up so will the battery both are working hand in hand. It's like your engine is hot and so will your spark plug be. For the safety of the parts and since lithium ion batteries are dangerous when overheated, it's a safety net.

For someone who's Russian. Your English is impressive I couldn't understand much from the screenshot but I am curious, people say the guru app is useless since it's placebo effect

Haha. Thanks I am Greek not Russian
The two screenshots just show how the one in the higher temp is still charging and a few minutes later it stopped and the other one with the low temp says that battery is overheated, AC connected but not charging.
The guru app I think it helps a bit as about 5%, but no more than that.

What is your CPU temps?

I just got my phone today but I feel like it is getting a little too warm. I installed system tuner to check the temps and seems like I am running about 47-50C on regular use. And it gets up to 60C while charging and It feels warm in hand. Curious to know what are your temps? Thanks.

How hot does your device gets?

I have been asking this in few threads lately and no one yet to answer. I installed system tuner to check the cpu temperatures and seems to be a little high compare to other devices that I owned. With regular use the temps seems to be around 45-50C and with heavy use and gaming it would go up to 60C. The device also feels a little warm around the camera area. I would appreciate if someone could check their temps. Thanks.

Haven't measured, but mine gets SUPER hot sometimes. Usually when playing games, or like last night, I was on skype for ~4 hours. It get's hot, but I would expect it or any device to get hot when doing that type of stuff.

I don't own one but those temps are right in line with the average desktop pc. I think once temps hit about 65-70C under heavy load, then there is reason for concern.

Mine got up to something like 42 degrees C yesterday while browsing. Got the temperature readout using Cool Tool. Heat was mainly around the top / camera area where I assume the antenna is.
38° C max and that's when i m charging and using the phone.

42 is not hot. Its warm. To qualify as hit it has to reach at least 50.

Something must be terribly wrong. I notice it gets warm slightly when playing around with custom kernels or gaming but not to the level where it is uncomfortable to hold. If you are on stock rom then you should contact google.
I think its because of the radio.. Hot when it isn't on airplane mode. Fine when its off

That kind of heat is an issue. RMA that pronto.
Download system tuner and see what the temperature is when its " too hot"
Mine gots rrally hot when running Angry Birds Star Wars. What about you guys?
I've had two N4's and neither one ever even got warm. At least not noticeable in hand. Even with extended gaming. Agree on the RMA.

With every electronic gadget using Lithium-ion batteries nowadays, it doesn't really matter how/when you charge it.
Some would argue to make sure to allow a full discharge from a full charge from a battery calibration point of view, so the battery meter is more accurate. It wouldn't affect the health of the battery itself either way.
Things like memory effect doesn't apply to lithium-ion. How often you charge it and how much you charge it (full or partial charge etc.) doesn't affect it much either. The only 2 things that can potential kill a lithium-ion is high temperature and letting it discharge far too low to the point that it cannot be charged up again. Note that all electronic devices will power off way before it even reaches this threshold.

Read this in a different thread when i was unboxing my nexus 7, i let mine sit for a while on the charger before i turned it on, but it came charged already. So far i have not let my nexus drain to 0% and the battery life on it is great, it can go for a entire day.

Sounds like it may be a corrupt download. Unless you plan to remain on the stock ROM just unlock/root it and then install what ever ROM you like.

Note 3 Battery Problem

I have a galaxy note 3 N9005 and the battery life is not what it should be. I've owned this phone for about 5 days. I always have power saving mode on with all the smart and air features disabled. I charged my device to 100%. Does anyone know how to fix this?
Thanks
Wow, that's some horrible battery life. I'm not seeing anything like that on my device though.
Did you condition the battery probably?
And of over 3 hour screen on time.
My advice: try to recondition your battery
As in, let it die, recharge to full from wall outlet. Do that about 3 to 5 times. Don't force it to die just use it normally so the battery will discharge power properly this will causes it to hold more charge.
If you do that and the battery still doesn't hold charge then your battery is good as dead.

Wow you get amazing battery life! Thanks for your help
Is your screen brightness set to 100%? And was what you're doing over excessively white? Because that might account for some of it.
Did you unplug it last at 100% battery, or somewhere halfway? Because from the look of that table, you unplugged it around 50%...

Do we have to "train" the battery to achieve max capacity?
is it battery defect or phone?
