When I have my phone plugged in and am tethering 2 worrying things happen.
A. The phone drains battery VERY VERY quickly, (yes even when plugged in). Quickly I mean like 20-30 percent in half an hour.
B. The phone starts to get very very hot. So hot that when I turn it off, it does not let me charge and instead the overheating icon flashes. If I leave it on, the screen and the capacitive touch buttons start to flash erratically and the back gets even hotter.
This kind of frightens me, is it happening to anybody else? If so can you please post. Also I am using Blazer ROM 3.8 if that makes a difference. Please reply thanks!
How are you tethering? Through usb or wireless hotspot? Are you tethered while on 3G or 4G? How is your signal while tethered? All these things are relevent so answer these these questions so we can offer you some advice.

Thanks for the quick reply. I am tethering through the Sprint Wifi Hotspot on 4G. I have 2 bars on 4G when I am doing this.
Need anything else?

Check your task manager and see how many apps you have eatting at your CPU.....and are you overclocked?....if yes...don't overclock while teathering

what rom you on?? When I was on blazer 3.8 it was like you stated. Since I've been on 3.9 it doesn't get nearly as hot or drain as fast.

Mine overheats when using Netflix over 4G and charging. I run my phone stock and really clean with nothing extra running. Sometimes I get an image freeze and a short sound loop and I have to force shut down. But usually it just tells me that it isn't charging anymore due to the battery being too hot. The battery is always cold, but the phone is hot.
The phone runs hot. Wot wah.
I'm on 3.8 (the first version) I got really confused when he released another one the same day? I have nothing else running and I have not touched any CPU settings, so I'll just have to conclude the phone runs hot. Can this permanently damage the phone? If so what can I do to prevent that. Thanks again for the replies!

Heat is the phone's worst enemy. I love PH and his work but you gotta stay away from heat. It shortens the life span of your phone.
Edit: he updated it today so I'd give that a try.

Yeah get off 3.8 as soon as you can, when I did the problems you mentioned went away. BTW I'm on his latest 3.9 and it is far superior in every way...3.8 didn't like our phones too much!

i've definitely had this same exact problem.. Phone/Battery heats up (>40C) and drains quickly with 4g and wifi tethering active. I think overheating the battery like this will shorten the life of the battery in the long run.
Maybe tethering over usb is the solution. fwiw my evo used to tether 4g without this issue. im using blazer 3.9 (upgraded from 3.7, wasnt ever on 3.8) stock clocks/kernel.
Hot LIPOs are less efficient in their discharging and will drain more amp-hours than if they were cold and doing the same things. Running them hot will also shorten their life, correct.
If you battery runs hot, swap it for a cold one* and wait until your battery is cold to charge it off a wall charger or something. These low C rated batteries we use don't really get toasty from just charging, but you are wasting energy trying to charge a hot battery over a cold battery.

This is gonna sound super ghetto, but it's what I do and it works. When your are running your tether, have the phone plugged in, take an ice pack and a couple paper towels. Put the paper towels on top of the ice pack and your phone on top of that and you're golden for about an hour. Keeps it at a nice 25°c

sounds like it would work... but there has to be a better way. I tether at work a lot (to get around pages i use like netflix/facebook and whatnot being blocked) what i've been doing is limiting my tethering based on how warm the phone is, when it heats up past 40 i give it a rest (and get back to work).
Helping me find a lasting fix to this problem will allow me to be less productive, and hopefully extend the life of my s2.
I have been meaning to make a thread on this. It happens when tethering only, that the phone overheats.
The reason being is the power management for tether I think got bonkered with the addition of 4g tether. Something is not optimized. The battery level literally deplete 10% within minutes
I've overheated to the point where my vibration motor makes noise, and got corrupt data twice. So now I have to tether with a glass of ice on my phone, ice pack would be better.
I appreciate the tether, but the trade off is ridiculous.
.: sent from my Samsung Galaxy S II Epic 4G Touch :.
See, this is weird... I've been wondering why my phone DOESN'T heat up appreciably while tethering, w or without 4g. My og epic always would for sure. I do the same type of browsing on tether with this phone (not super intense, just browsing, but it always heated up the og epic) and the phone stays cool to the touch, or maybe just barely perceptibly warmer. Not even enough to make me check batt temp.
I'm running stock rooted, using sprint hotspot hack. No overclock. FWIW.

I would just take the back off the phone and have a small fan blow into it. Also I heard underclocking to 800 MHz while tethering will keep your phone cooler.
Thanks for the amazing replies people! I recently switched onto 3.9 and to calibrate my battery I charged to 100% and tethered on 4G for about 2 hours no problem. So I suppose it was just some problem with 3.8 then?
Ditto
Same thing happens to me but from daily use. I'm on the web a lot. I'm rooted but running stock rom. It's been really bad the last few days, especially after I changed the 4G idle speed. So that may be one issue for me. Oh well
I experienced the same problem , but I think it's due to tethering as the CPU is processing and forwarding more traffic . I fixed this by limiting the tethering download speed . I used an app called bandwidth ruler for that . and my samsung SIII is relaxed while tethering
APP:
Bandwidth ruler free on goolge Store

I have no clue what is going on with my phone, but my battery is doing weird stuff.
1. Sometimes it shows its charging when its not.

!!!!!!UPDATE!!!
I called Verizon on Monday who told me it was a known issue and a software update would resolve it. However I told them to send me a replacement anyway.
Now today..I plugged the phone into my USB cable connected to my computer and it started smoking!! I swear I zapped something. It still works, but now its all weird. I going to have to use the wireless process of getting it back to stock and locked..so we will see how it goes.

Not that I know of, its running CM10 Euroskank.
I also noticed that when I plug it in to the charger it takes about 10 seconds for it to recognize that I plugged it in and start charging.
I had a similar issue on the GSM 4.1.1 stock ROM where the battery voltage was being misreported (using Battery Monitor Widget to check values). Sometimes the voltage didn't decrease with use; sometimes it even increased without being charged - your battery graph seems to show this too.
This problem developed literally overnight and didn't rectify itself over multiple charge/discharge cycles. I changed ROMs to see what would happen and to my relief there were no further problems.
As an option you could try clearing the battery stats in recovery.
Given that a few people in this forum have had sudden battery weirdness, and that a fresh ROM fixed it for me, I suspect there's a rare software bug at work here...

-1 on the clearing of battery stats. It has absolutely nothing to do with it. He'd get the exact same results by changing his ringtone or something else that's totally irrelevant.
Battery stats has nothing to do with the reported percentage of battery. It cannot cause power problems. And it will not affect battery life.
How is it that the wives' tale of clearing battery stats still persists despite the fact that a Google engineer has debunked the myth and that debunking has received wide publicity within the android community?

I had a very similar problem with galaxy s2. My symptoms were that it thought it was charging when it wasn't, it thought it was usb connected when it wasn't, and my battery graph would just show one long spikey graph for as long as the phone was on. I posted it up and someone clever identified the problem straight away; a short in the usb charging area.
Have you ever spilt any liquid near the usb charging port? It's a replaceable part and I'm sure it's available from the usual place (ie. Ebay).

Also, the text file that has the "battery stats" is erased when you reboot, which is the same as manually deleting it with CWM or whatever.
Alright first of all, i want start off by saying that i LOVE this phone, both in terms of hardware and software, however, theres is a HUGE problem that i just can't get through and its the battery of this phone...
It is simply unbearable.
I have posted the screenshots. This screenshot is taken after 1 whole night of charging. In 5 hours or so time, I've use the music app for about 1 hour, talked on the phone for about 5-10min and sent about 10 text messages. I didn't do any web browsing/videos/gaming. I have also disabled LTE and turned my brightness to minimum with eco mode on. These small things drained my battery from 100% to less than 10% within 5 hours which i find to be completely unacceptable.
Last night, with me browsing the web on the bus for about an hour or so, it drained my battery from 85% to 3% by the time i got home...
I've looked at the battery life thread and it seems like im the only one experiencing this issue. Also not only does it drain SUPER fast, it takes a good 4 to 5 hours to recharge this thing. Which means it takes longer to charge than to use up even with minimal use...
Do I have a faulty phone and should I get it replaced???
Something's amiss. The only time that I've gotten less than 10 hours, is when I had my work email connection set up to "always connected" and wifi was turned on. Even then, I got 9+ hours of battery life.
Disabling lte is part of the problem. When the phone is in 3g, it uses fast dormancy which LG did not implement very well and it runs the CPU constantly. I encourage you to contact LG and your carrier and complain. don't let them tell you about background data or applications running the battery down. With the same apps running, this does not happen on lte. This can easily be verified by enabling debugging and then capturing a logcat from adb with lte both enabled and disabled. It will show fast dormancy trying to set network states every second. I spent a lot of time trying to get this issue recognized, but they kept saying that it had not been reported and was not a known issue. Let's make it a known issue so they will fix it.
How about actually showing us what you used instead of screen shots of %.... would be helpful...

Yeah, I've been quite impressed with my battery life on this thing. I made it from 6:30am spent about 2 hours tweaking it and setting it up, then messed around with it through the day. By supper time I plugged it in and it was at 63%.
I don't have the phone, but right off the bat i'd say it was whatever was causing your mediaserver to go nuts. Either some media app, YouTube, gallery etc, wouldn't say its a faulty unit, just mediaserver gone rogue
And damn i want this phone...

Well, a little update to this thread, i've disabled every different kind of syncing possible and i've been able to pretty much double my battery life from before, which is a lot better but i still wouldn't consider this to be good battery life.
I've been reading many posts regarding battery life, and it seems like there is some issue within the software that prevents the phone from going into deep sleep which is causing the lack luster battery life. This issue is on both the optimus g and the nexus 4, so i hope the devs may look into this issue when they are building custom roms for these two devices!

You definitely seem to have some weird issue's. My Optimus is great for battery life. My previous phone was an Xperia Arc and this has significantly better battery life without even running it in "eco mode". The only time I have noticed less then stellar battery life was when I had some app's running in the back ground that would keep refreshing/updating which kill's the battery.
Androids usage readings are inaccurate. Please consult this: http://forum.xda-developers.com/showthread.php?t=1179809
From what the picture shows I would guess its your 4G connection. A Hardware fault is improbable. And forget these things like "eco mode". Even if they underclock your cpu it won't give you a real benefit,
I've had great battery life on mine. Even when I've been geeking out on the device for several hours during the day.
Perhaps you are on the cusp of LTE coverage? If so, then the radio can kill your battery while looking for a signal.

I also have amazing battery life IMO, coming from a Galaxy S. I have no LTE in this area so am using only HSPA. Using the phone with casual use, I can easily go a full 24 hours on a charge. With very very heavy use I can go from 8 am till around 11 PM. I am very happy with the battery life overall. I'm running on "eco mode" FWIW.
Hi All,
So recently I have been having problems with my battery life. It's not lasting as long as it should. However, I do not know whether or not its my data cable, the device that plugs into the wall, my battery, or the charging port in my phone.
I got my phone from best buy, but it was more than 30 days ago, and I have no insurance on it, so I cannot get a replacement without sending it away for at least $100.
Any tips?
Well what battery life are you getting? Get into the Phone settings and then battery settings and post a snapshot of the graph here. Additionally you can also install Batterystat it will give you a full analysis of what's using up your battery power.

I think I may have narrowed it down to the battery itself? I have some battery apps that tell me the health is "good," but what does that really mean? My charging cable is iffy, because sometimes it works perfectly, charging to 100 just fine. However, other times it charges 20 percent in 9 hours. When I used my friend's Note II charger, it worked perfectly every-time. But the fact of the matter is, when my phone does charge to 100 from my cable, I still get not the best battery life, which leads me to believe it's my battery's fault. I am going to test out charging my phone to 100% with my friend's cable tonight, and see what happens tomorrow. I will also get batterystat and report back.
Also, this may be important. When I first got my phone, battery life was AMAZING, really quite astounding. It's just kind of dropped down, like a slope. Not a sudden, dramatic drop, but incrementally.
As for the battery info below, here is what went on today. I unplugged my phone from 100% at around 7am. It is now 6pm. Today, my phone was barely used, just sitting in my pocket with wi-fi on. When I did use it, I sent two very quick emails, played scramble with friends for about 45 minutes total, took a few photos, listened to music from the music player for about 15 minutes, and that is really all I did. I feel that my percentage should be much higher than what it is listed as.
Here's mine as you can see I'm getting almost twice your battery life. I have a few apps that i use everyday which are basically whatsapp, xda, chrome. I don't have many apps that would wake the phone constantly and if there is then I disable them from starting up when the phone is not in use. The best tool you can use for something like this would be rom toolbox pro. It's multiple system tools in one and it works great. I'm currently on Omega V10 with perseus kernel. Also I don't connect to wifi much and network here is weak and on 2G but even though I still get this battery life. In areas with good signal I get more battery life. Also I've dropped my phone twice with impact points on the corner, and just minor scuffs but that didn't effect the phones performance or battery life so I doubt it has affected yours.

Also I've overclocked, my processor to 1.8ghz and undervolted between - 50 and -100. So i get minimal power wastage from heat build up. Also you can set a black wall paper with a dark theme.

Unfortunately, I am not rooted, and haven't planned on doing so ever. Is there anything else I can do to fix my problem? I did download batterystats, and am waiting a few days though to see what it tells me.
Also, I used a different charger just to see what would happen today, and even though its been off the charger for 2 hours, it's already down to 94 percent. So I am thinking that there is either something wrong with the battery, the charging port, or could there be a bug in the phone's software?
I am thinking of getting a new battery, and seeing if that fixes my problem. I'm just so irritated because battery life used to be amazing, and I don't know what happened.
Maybe try a factory reset. Maybe something else has been using your battery.

That's what I was thinking. I will probably do that and report back, before going out and buying a battery or something. Is it possible that, although not reported in the battery info, that an app could be rogue or something or taking up battery? I don't want to do a factory reset and redownload a bad app.
Update: I tried a factory reset. It seems to either be worse or just the same. It's been an hour and has dropped to 97 percent, but I have made a couple of phone calls. But compared to before I did a factory reset, it dropped to 96 percent in two hours while not doing anything.
Keep your phone on charging over night.
Then let it drain to zero no matter what.
Do this 3 to 4 times and then
Leave it for charging overnight.
Then while it is already charging use battery calibration.

Quick Update:
I did another factory reset after I said the initial one didn't help. It looks like it may have helped, although I still have not gotten the battery life I used to have.
I found an application here called betterybatterystats, and have downloaded that. I will use my phone throughout today, and will post sceenshots.
If need be, I will take your advice about charging and draining and charging, and then do the battery calibration.
Here are my most reset battery stats. Screenshots are from the battery setting area, and betterbatterystats
Maybe I am just being paranoid and nothing is wrong? I can't make any sense out of these readings, but I hope someone else can.
first of all change you cable if you are having that kind of issues. Mine in my galaxy ace was having that problem, it was like connect/disconnect without any reason and it didnt charged my phone at all. I noticed it when it was too late, the continous on/off kill my battery. When I say kill i mean it just lasts 15 min in 3g with screen on and it happened to me in 2 official batteries.
good luck!

So it has happened a couple times where the tablet says it has 28% or so and then my daughter uses it and in about 5 min the battery is dead. Has this ever happened to anyone, is it from being uncharged for a while and by that I mean I haven't charged it for about 3 days? Its not to big of a deal just weird.

I've had that problem, particularly when using what I assume are labor-intensive apps (Skype, Candy Crush, The Room). It really bugs me, since the tablet ought to be able to handle these without significant drain. But I'll see my battery go from 40% to 5% in a matter of minutes.

I made this account just for this EXACT issue..... same thing has been happening to me, battery loses CHUNKS in the matter of seconds, its not a calibration issue, i have fully charged it many times.
i just got not even 5 hours of screen on time with my note.... freekin pathetic. its a fresh flash of clean rom too. battery drain like crazy... i think im gonna try to odin to stock and send it to samsung... i think this tab has a battery defect.

I have the exact same thing. From about 30 - 35% it drops in a matter of minutes until empty.
Did anyone figure out yet what causes this? And is there a solution to it? I also sometimes have issues to power on the device. When pressing the power button it doesn't respond. I had this a few times now, after pressing the button for about 10-15 seconds it finally switches on... Anyone else had this issue too?
Yes im having the same problem. As im viewing this post, ive lost about 3% battery. Last time i buy a samsung tablet. They dont optimize or update to patch their mistakes. Horrible.

I had the exact same problem......
And the solution is.....
FORGET ABOUT IT... I know that it turns u crazy and makes u just watching the battery percentage waiting for it to drop....so annoying
But what I decided to do is just forgetting about it and use it normally and dont let the battery percentage go too low and by time and charging and draining the battery over a month or so it became perfect!! It even gets charged in less time (about 4 hrs)
agree
This has now happened to me twice. Id be hovering at 35% ish, and in 20 mins of video watching im down to 16%. Something is amiss
I never had this problem until i recently Rooted the device and installed Clean ROM. Im thinking i should go back to stock firmware with Root and see if this still occurs. Worrying
If people let the battrey drop to 5% then switch off the device. Then put it back on and then connect charger and charge to 100% in one go without using until it tells you to unplug....see if that works.
Obvs dont always do this....this is just to try to calibrate battery. Under normal conditions you shouldnt let the battery drop below 30% before charging anyway to protect the battery from severe degredation.

Had the same issue with mine, sent it to Samsung for what I thought was going to be a battery replacement. They just flashed a new firmware on it and that fixed it. They also put 2-3 scratches on my flawless screen. Idiots.
However, overall, battery life SUCKS on this tablet. It's way worse than the older 10.1 which I am using now because I can't get rid of Samsung's API locked sPen gestures on the 2014.

The problem might lie in the usage of a certain app... dolphin browser for example... enable flash on it and your tablet drops 10 percent a minute or more ... you should look if the tablet is draining also by doing nothing by just having the screen on.... there is also the possability of having a bad external sd card that causes android to loop media scanning nonstop....
Im rocking android for some time now on multiple devices... and it was always some rouge app which caused this ... causing wakelocks and stuff... you can look for whats draining battery with wakelock battery monitor... or better battery stats... try to keep android as clean as possible ... some apps just drain like hell.... even facebook ... because of background services

This has now happened to me twice. Id be hovering at 35% ish, and in 20 mins of video watching im down to 16%. Something is amiss
I never had this problem until i recently Rooted the device and installed Clean ROM. Im thinking i should go back to stock firmware with Root and see if this still occurs. Worrying
