Does your note heatup?

I've been using the note for a few days now, i've noticed that it heats up quite a lot. Under charging it is understandable... But even when the screen is on for is say 10-15 mins straight... Does anyone elses phone heat up too?

yep, every smartphone I have used does that (GS1,GS2, Note, Tab 7" tab 10.1) and some feature phones do it (iPhone, HTC wildfire etc).
Think about it, dual core 1400mhz running, and batteries always heat up with heavy drain and charging.

Mine has normal temperature under regular use (IE a browser etc. - not really causing higher load), gets quite warm if playing a game for example (higher load, not sure how high).
How long does your battery last? (heat = energy)

I used to have over heat issues but eversince i use franco's kernel 6 the issue has gone away.
i use sfock LA4 with root, bloatware removed and franco's kernel. all good and no heatind issues even when charging.

There is an app called "Elixir" that can monitor the temp of the various sensors within the phone. I've used it on every device I put a custom kernel on. Setup a homescreen widget so you can see the temp at all times. If it tops 45c then you panic a little and let it cool down

which rom and kernel did u use?

Mine heats up only when I charge. I don't mind, I like warm stuff.

Mine gets pretty warm too, especially at extensive use and charging at the same time.

yeah mine gets warm too, especially when browsing using Dolphin browser. The highest temp it touch is 51 degrees. Other than that it quite ok. Usually temp between 28-31 degrees.

When I was on stock rom and connected to gps +charging at the same time, my note used to heat up to extreme temperatures. enough to make me want to shut it off to avoid any hardware damage to internal circuit. It used to become burning hot at the top part of the phone. Now I have LA4 rooted stock rom with bloatware removed and using franco's kernel #6. Now my phone barely gets warm when I am charging and using gps at the same time.

I am on rooted la4.
Exactly what is safe to remove in terms of "bloatware"?
Did you just flash franco kernal 6 with mobile odin over the rooted la4?

Yes, my phone used to heat to levels you couldn't even hold it or touch the screen or your finger would burn. That happened with GPS or PocketCloud. After putting up Franco's kernel, heating is totally gone.

flash francos kernel in recovery from cwm. I deleted all samsung apps and all the apps i wll never use. the list is long. there are threads where people list the apps that can be safely removed.

I'm in the boat as gent0r mine will get fairly warm when used under heavy work and charging. But its alarming at this point. Not like sarius where he thought it was melting his case!

mine always with <50c still acceptable for me

I used Franco's latest kernel and my Note's temperature suddenly went up.. it raised the heat more...
I reflash back to Abyss Note and the temperature is back to Normal again..
Usually heating issues are caused
1.) when your using Data Connection thru Carrier (surfing, auto-syncing emails, news feeds, twitter, facebook and etc.)
2.) when your playing graphic extensive games
3.) and lastly when your Note's display is always ON, all the time (like watching movies all the time.)

mine doesnt really heat up, except one time when using titanium backup. the process just stopped and the phone got extremely hot.
it never does that in normal usage though

we must remember we are taking battery temperature as an indication to CPU temperature. In reality your CPU could be getting fried at 50 degrees battery temp depending on circumstances. We news to access the CPU temp sensor if there is one. Does the phone shut off when overheating? Like a failsafe? Or is it just the hardware failing?
Edit - the reason I say this is I remember on the n900 forums a guy dismantled his overclocked phone which was dependent on battery temperature (safe temperatures were established and overclock was dependent on battery temp) and when he saw the state of the main board and scorching around the CPU he was very shocked.

Its always best to reboot 2 or 3 times after flashing a new rom or kernel. Also wiping cache n dalvik helps.
While flashing new kernel, always use kernel cleaning script. I have been using battery indicator pro till now, will try the mentioned sw 'elixir' n see the difference.
Franco v2, speedmod v1 are better kernels imo.

[Q] Galaxy Note Battery Issues

Anyone experiencing battery heating issues?
The battery temp stays from 25C to 36C when not in use/constant usage.
however, after prolonged period in lockscreen mode, & i unlocking to use it, it heats up pretty fast, playing games worse; ends up with 42C to 48C, highest being 51C.
is this a common issue? (as some of my friends have this prob too), and it's only the dark blue Note.
any ideas for fix?

Mine gets pretty toasty as well. If I use it while charging it, I've seen it get to 48 degrees.

My Battery died tonight. I woke up after i burned nearly my arm becaus of the hot device. it boots shortly because of demaged battery but i dont know if the Note is ok. display issues. It was on CM 04, on 03 i dont have recogniced any heating problems. If my new battery arrives i must test if it has no damage.

@gilrad: i never use my phone when charging so that i can get a more accurate charge.(just my own thinking) still it can get abit hot(but this is the normal heating)
just referring to light/normal/heavy usage.
@wtwo2: how did your note get hot in the first place ?

it was on charging. it boots shortly with battery and charger in but then goes off(usb port). battery doesn't load any more
edit:with charger in wall it boots normally and i can use it but i testet it only shortly, better wait for new battery.
Until now 'no' issues with device.

Yep, same here on my Note, International version from Latin America, GB, rooted.
It gets hot when I do intensive activities such as:
- Watching full featured movie (1+ hour)
- Playing games with tons of action (not simple one like Draw Something)
- Browsing website with heavy content (Flash, ads)
So far, has NOT resulted in too high of temperature such that it burn my hand.

Mine is heating like toster
My note is heating up very fast. I found when it is heating so badly
1.When you search for 3g networks or wifi signals or when downloading at high speeds.
2.When you start ur flashlight for 5 or more minutes
3.When you use your GPU at most for example watching HD video and playing high quality games
I saw my battery upto 58 degrees
I saw my battery draining like seconds when i started watching a hd video it goes on decreasing from 78,77,76...............27 in just 20 mins time with 3g activated.

Its odd that people report that the Note gets hot while watching videos. Are these online flash videos or something? I use my Note to watch a lot of HD videos, and it always runs cool. It may be to do with the encoding on the video or the player... I tend to encode to High profile H264 and use mVideoplayer. AFAIK, this allows GPU decoding which runs cooler and draws less power.
Some players use the CPU (the early versions of Mobi player did this I think), which gets hotter faster and drains the battery quicker.

Mine often gets hot only after i've left in lockscreen mode for quite a while -> wake-up -> use apps before it cools down after quite some time, with the app still running

and now it's getting a bigger drain even when i leave it locked while i sleep. dropping from 100% to 60% in one night and from battery graph, it shows that my phone's getting wokeup periodically - any ideas..?

and now i have to reboot often once i realise the battery cant enter deep sleep mode -> battery drain. it's monitored by betterbatterystats where my deep sleep time is 0s, anyone got any ideas what's causing the wakes?

Note 4 running hot, and high battery drain

Hey everyone,
My note 4 on 5.0.1 running any rom (stock, poprocks, TekHD) runs super hot. The area on the screen that is right below the camera is unpleasant to touch. When running a cpu temperature monitor I seem to identify around 60c and when Web browsing and scrolling though pages it'll go up to 70c. This also seems to be killing my battery life. Over 10 hours I'll be lucky to get 2 hours sot.
I've gotten wld and bbs and don't see any crazy wake locks that aren't supposed to be there. Largest one is my Google play music which I do use. 2nd up is Bluetooth, I'm guessing because of my android wear device. I've also done clean installs where I do a correct wipe then don't install any apps. Still horrible battery life, still lots of heat.
From reading about it sounds like the heat issue could be a bad device and I should get it replaced? Should I try picking up a new battery?
Over the course of writing this post, about 4 minutes I've gone from 17% to 10%.

Reinstall rom with factory kernel and install kernel adiutor apk for cpu control from google play. Im using rapture 3.0 without issues and battery pretty good and temp is normal.
Sent from my SM-N910T

Same problem here SM-N910G on 5.1.1 stock ROM. Installed a new genuine Samsung battery, NC. I hit about 60°C when at idle, 65°C when browsing. I wiped davlik cache and cache on teamwin, which seems to have helped a little. Battery is lucky to last 4-5 hours tops.
Did you find a solution? I thought it might have been from using Blitzwolf and Xaomi chargers, but it's the CPU getting hot, battery stays at 40°C

Are you using a custom kernel? I had an issue with a bad kernel setup and it restored my settings automatically which was the cause of my battery drain.

Hi,
I would not worry to much if your device is 30+ it's normal. Now if its touching eg
50.. 60 + C start worrying.
My phone is at moment 31.2 C
Just remember...
Temperature, also depends on "other" factors also.
eg.. If you have an phone case /cover,
Temperature of your surroundings can play
a role.. etc
What workload it's doing. fo long period of time.. eg games, movies, music etc
But 30 C plus, is normal.
I sometimes let my device run over 40 plus.
Good luck

Is this something related to marshmallow??

Only when wifi connected then temp gOes up otherwise its normal below 30

i am getting same amount of heat, residing in Karachi and updated to MM. ?By the way, how is your battery life? for me it simply sucks as compared to Lollipop. I even factory resetted.

Battery Drain on 9.0 Pie

Hi people,
Can someone give me and opinion of the battery drain with a note 9 on pie?
I bought my Note 9 four days ago and updated to 9.0 pie right out of the box, I think that battery is still optimizing for usage but I find it very bad with battery life and SoT. I'm posting a screenshot, if you have some tips ?

I'm with exynos, 50% brightness display, exynos version, Bluetooth off

You answered your own question! Battery is still optimizing for usage! You have to give it 10 or so days before it battery gets better! Also turn off Wi-Fi, Bluetooth, 4G, Sync, turn the screen off turn everything off lol messing with you 2/3 weeks mine took to settle down!

I'm having the same problem. Android System was waaaaay lower before. It's always at the top of the list now. :/

There's plenty that can be done, especially if you have the exynos version of the phone.
-Unlock bootloader and install Dr Ketan's rom, it is fantastic.
-Then apply endurance kernel.
-Use Magisk manager to apply module: Universal GMS Doze
-Use Mtweaks to apply a few kernel tweaks
I haven't gone this far just yet as I'd like to see how the phone goes without it for a few weeks but you can also install greenify or if you want to really get serious, greenify xposed module. Personally I find the battery life of the note9 to be fantastic but you must keep in mind that the screen is enormous and hi-resolution. Whenever you are using the screen, especially at a high brightness level the battery is going to drain - it can't run on good intentions.
Try turning down the brightness. If you are absolutely serious about battery life over everything else, you can disable auto-sync, remove the official facebook apps if you have them and replace them with faceslim and lite messenger and modify the notification settings.
Doing all of the above and only turning the phone on when you need to make a phone call or use navigation etc should net you an easy 4 days+ of useage but then again, you may as well have bought a $30 powerbank phone.

Tripping Knox hardly sounds like a good idea if I'm honest.
If your Android System is high then something in the background is wrong. You could try clearing cache then give the phone a couple days to settle

Battery life varies significantly with any phone and any version of Android.
Often we assume, wrongly in my opinion that a very large factor in battery life is the version of Android , hence the numerous posts on this forum who wish to or have gone back to Oreo, for reasons I consider delusional.
What apps you have on your phone and how often you use them are significant, playing games that use lots of cpu and gpu is going to impact battery life.
Web browser and YouTube rather less so.
I have experienced lower and higher screen on time and standby time with the same apps and version of Oreo, and Pie (both on beta and released)
I am on Exynos Note 9
Bought and used since release date Aug 24 2018, haven't used so called battery life friendly charging (20% to 80% etc)
Can run battery down to 0% on occasion and charge to 100% using fast charge, often left on charge overnight.
Yes there are some optimisation that may help and I use a few, I couldn't tell how much they help though as just varying usage is a greater factor in my opinion
Battery performance from yesterday
18.5 hours total usage with 9.25 hours screen on time
