high battery heat !

when i listen music for about 30 mins + and running some programs such as adobe reader or opera, i can feel a warm in my hands from the battery. actually its more like to be said a relatively high heat felt by my hands !?
is this high battery heat normal? i mean for an everyday usage.
tnx in advance
Note: i did search but didnt find anything about LEO battery heating.

The battery can sometimes get quite warm, but it should never be hot. If it heats up to much you should probably get it looked at.
The battery in the HD was a lot worse than this. I think there may have been some issues, but HTC have worked on it. Thankfully, I don't know of any HTC phones exploding anywhere yet! lol

mine gets hot as well some times especially when I use igo in my car and charge the phone at the same time but also when playing a game etc.. but I read in the manual that this is normal... although I believe heat to an extent that can burn your hand its not normal.... mine never got that hold
just my 2 cents

Hello,
If you are using something like Opera, coupled with a number of applications that are cpu intensive, then you are going to get high battery drain which equals high heat output. Some of the heat will be coming off the cpu as well but the end result is the same.
The problem is worse if you are using wifi and/or gprs and you are in a low signal area, which means that the device and the battery need to work even harder to serve your needs.
If this happens again then check your location relative to wifi and gprs and/or reduce the number of intensive applications you have running at the same time.
If this fails then you may have a fault; however I think one or all of the factors mentioned above are linked to your issue.

ok tnx for replay guys...i accept this as normal situation, and yes i definety like to use igo8...and really its soo nice to have pda such LEO that can easily open and run several such programs!

Question on internet browsing on the note

Does the battery life in this area improve the more you use the battery? At the moment there seems to be a big difference in how it performs in this area compared to the battery life for other functions on it. When browsing the net you can literally see the battery draining away.

Don't think this action is THAT much of a battery concern, I suggest 3G data connection is the main issue, which in the case, shouldn't be much off difference to the other options at all.
The other issue was screen, yes it is larger, higher resolution, but as a user from N1>LG2X>SGS2>Note, I do not see big difference too, all device mentioned would last me from 12~14 hours with my usage, the 2 hours diff seems related to the different daily usage instead of CPU/Screen etc.
Just a reference:
I had these sync on ALL time:
Contacts/Calender/Twitter/G+/Google Reader/Whatsapp/GMail/GTalk/Latitude
On Wifi only:
DropSync
Normal usage, web browsing mainly, G+/Twitter/GTalk/whatsapp a bit, not much phone calls (45~60 mins), most of the time Wifi (at work/at home), Note would last me 13~14hours.

I have had devices before with suspect battery life, but on them it tended to get hit whatever you were using. Whereas with the Note it seems to have a decent to good battery life on most things, even with various synchs going on in the background. But as soon as you venture online it takes a big hit. It must be related to the screen, which shows in spite of claims at the time that Super AMOLED still eats battery.

are you browsing through wifi? wifi eats my battery.
Also many web pages have white backgrounds and that is a real killer for amoled. I converted opera to default to green text on black and that helps a lot.

A famous site made some battery tests and the results speak for themselves:
around 9 hours of video playback, but 3h30mn of wifi surfing...
The OLED screen burns the battery because everything is white on the web.
Web surfing is one of the selling points of this phone, but this phone can surf the web only half the time of the best smartphones around:
EPIC FAIL !!!

There's a lot of questions regarding what exactly that test is, since that doesn't match what people are seeing in real life.
I'm guessing they had their screen at 100% brightness.
I find this phone extremely bright, actually, so that's quite overkill.

There is a power saving feature in the stock browser, I think it is added in new firmware. I am on KKA firmware.

Is there any conclusive evidence if the battery drain is from the WiFi conenction or of any browsing will eat it?

I don't use WiFi so I do all my browsing on 3G only. I can have it where my Note only shows a fairly small drain through calls, texts, emails etc. But after say only 30 minutes web browsing the battery is showing a big dent in it.

I think they had it at 50%. Also a real life scenario imo, would be having the brightness at 25-30% and reloading a page every 20 seconds on a good optimized battery. Then only we can talk browsing numbers.
But since they tested the battery and compared it with the same/similar settings setup's on the phones, I guess an alternative browser to work on those "white" backgrounds, is a must..

How did you do that? I'm using opera mobile and I'd really like to reverse the colors or something for night browsing so it's not so bright. I haven't been able too find any such settings. It bothers my girlfriend sometimes if I'm up late at night browsing the web and it lights up the whole bedroom. Red text on a black background would be optimal. Before the Note I used Cyanogen Mod which has a render effect you can activate in the settings to disable green and blue sub-pixels for a red night vision effect (or other combinations for other colors.)

Tablet charging and running hot

I started having this weird problem the past few days. My tablet seems to become very hot while charging. It also runs quite hot when on wifi. As a result the battery performance seems to be degrading. Any light on this...our has anyone faced similar problem. A possible solution to this would be highly appreciated.

if you read the user manual which comes with the tablet ( pdf is also available on official website) they have mentioned it in manual that tablet can get hot while charging and using processor intensive tasks like wifi and games. They have also said that it will not affect the longevity of tablet or battery in any way . My tablet does get a little warm while charging and after heavy usage. i guess its universal

I wouldn't worry if the tablet was getting a little warm. But the moment i turn on the screen, the left side of the tablet. both back and front become exceedingly warm even without running any intensive programs. The issue started about 2-3 days back only. i never had this problem before.
While charging the tablet is literally quite hot, and like I said more on the left side.
I think I need to go to a service center to get it checked.

If the battery gets hot, the effects are similar to those of overcharging. You know how bad overcharging would be. So I recommend you to take a deeper look into the issue.
Taking it to service center is a good idea; but since the service center would wipe your tablet clean anyway, so why don't you check if there are any background processes that have been causing this acting up lately? Messengers like whatsapp/line, screen lock apps, weather and news widgets, adware/free games with ad are examples of the apps that would be taking background resources, you would like to check whether you have installed new apps like that.
Most background processes usually won't cause your battery to act up, except when they got stuck on something. You probably couldn't fix it by yourself so you would better track them down and remove them.
TasKiller is one of the app that could show you background processes. There are countless others good app for the same purpose.

My tablet has been on charge (while off) for almost 24hrs and still hasn't fully charged yet.
What gives?

Do you use the stock wall charger to charge it?

phone getting a little too warm.

Had the phone about 3-4 days now and so far been very please. Its a sim free UK phone and has been updated to latest official software as far as I'm aware.
My only concern is that the phone seems to get overly warm in most situations. I don't mean when gaming etc as I don't really play games but just general use. The back and sides seem overly hot to me.
I was under the impression this phone had the later 810 processor and had been throttled to stop exactly this problem?
Anything else that could cause this? Do I have a faulty phone or do others get warm?
I've also noticed an issue with signal strength and reception in that the phone seems to often jump from 5 to 0 bars.
Any help would be appreciated as I'm wondering if to exchange it or return for different model.
Thanks

Really just me?

Poor phone signal in area? Could be causing phone to warm up a bit more than usual, that or you have something else hogging down cpu in your phone.
The Qualcomm 810 still generate a lot of heat when the big cores goes online, v2.1 only slightly less aggressive. Same goes for my gf Xperia Z5 Compact using same cpu.

Thanks for the reply.
I've noticed it when using the phone while on network or WiFi. I mean it can be noticed after 10mins or so of Facebook, video playing (YouTube) or web browsing.
Also while using maps and having the phone on charge while driving really heats it up which I guess would be normal?
Have to have it on charge when on maps as it seems to drop 1% every minute

Charging while navigating will really make your phone almost glow from the heat, perfectly normal for this SoC, especially if you also have your screen brightness turned up to max.

S7 edge overheating

Hi guys,
I just got a new s7 edge. Been used for two weeks now.. it gets quite warm and at time quite hot suring operation like browsing web youtube checking emails.mostly the top right side and camera area. Im not sure if its a defect or not.. it doesnt get to the point where the phone shuts down but its still warm..i know the normal stuff like getting hot during charging or using the phone during charging. This is when the phone is being used and off the charger .
Simple tasks 30 to 40 degrees celsius youtube and web browsing it goes between 40 to 50 degrees. And for games it goes upto 60 degrees celsius..
Is the phone meant to be this warm/]hot ??
Please help..
I tried the normal procedures. Safe mode , format etc . I disabled apps. optimised apps etc.. still quite warm. When the phone is not in use its cool as a cucumber .

Really weird. I can play games with really sick high end graphics and the phone stays quite cold. The only moment when my S7 Edge gets quite hot is when I record slow motion video.
How is Your battery life? 4-6 hours SOT is normal. If You have less then You should check what app uses Your phone.
Also You can try first, formating the phone(data etc) and then flashing new rom with Odin. It will rewrite whole system partition.

SOT is excellent i average between 4.5 to 7 hours..
My app usage is fine..they say certain apps can make it warm.. I am using cpu z ro monitor the temperatures..
Not sure whether i should return this phone and get another one. Seems there are people with overheating s7 edges..

Well I guess if it doesn't bother You then You can keep the device..

It's a problem with a lot of the samsung phones I've previously had (S3,S4,S5,S6,and now S7 edge) on the bright side, it keeps me really toasty during the winter weather.

This is the first Samsung phone I've ever owned that doesn't get warm. Its the exynos version. I would be worried if yours is getting very hot for no reason.

It gets warm while i start using apps.. like browsing the web pn google chrome and listening to music on google music . Goes up to 40 to 50 degrees celsius..
On the other hand watchinf a video on vlc media player the phones nice n cool..

CPU can get to 80C and that's still in range for normal work, so unless it gets choppy or shuts down - don't worry. see what apps are the most battery consuming ones
