Battery draining fast, bottom of phone very hot.

What's at the bottom of the phone the cpu or radio? Whatever it is it is being taxed like crazy by something when the phone is idling with nothig running, including widgets.

Same here. After the recent update Im still getting the stuck at 90% indicator, and after I disconnect the phone's bottom will stay hot for the rest of the day... I'm worried it might blow in my pocket.

It's actually below the battery that gets the hottest, so I doubt the battery is in danger of blowing; can't be good for it's longevity though. At least for me it seems to be associated with charging, so actually doesn't seem bad while in pocket.

Seemed to be push exchange email doing it.

Can anyone get that to happen? Cuz I can't....

This happened to me last night after rooting my phone. The phone was hot and the battery died on me. I read on another forum someone posted that the exploid executable was still running in the background and you need to kill it manually from the shell or reboot. So that might be the cause of it.

I can't get it to do that either tried 10.

I took mine back on the first day after I bought it when it did that. It was also locking up requiring battery removal 5 times in the first day. The kiosk where I bought it tried to tell me it was the network being overloaded was causing that. I said 'BS', either give me a new phone or a loaner till you get me a replacement, so they gave me a new phone on the 16th.
Have not had any trouble with the new one. Battery lasts three times as long as my evo did.

Well after fully charging and draining my phone about 5 times, I'm seeing that it still didnt last more then 4-5 hours with minimal use. I just went to my closest Verizon store and got a new battery for free. It's only been 4 hours, but my phone isnt as hot on the bottom( by speaker) and its still at 78%, which is much better.

I thought the phone reported in 10% increments :/

Funny I thought I read 78%... now its says 70%. Maybe it was always 70.

battery overheating

hi guys..just got SGS2 and I have battery overheating problem, I saw a lot links on google with that problem but could not find solution...is there a soultion for this kinda big problem?

It's not the battery..it's the phone and processor overheating, working nonstop due to constant updates of apps, searching for signal and so on. It's like a car revved up on traffic.
Try to find out what's actually running on the phone, you can start by reading battery related threads.

thank you for your quick tip...for example, all apps are down, i only use browser and after 10 min it is so hot...so there is no any custom rom here that reduces this heat a bit??? seems little bit to much

There has to be something running in the background..could be apps updating, or phone searching for signal(especially if you have wrong modem installed).
I personally check Every apps I installed, and make sure they don't do auto update. Quick check, try to turn off background data, and then auto sync (both in setting). See what happened.

To my experience
Using wifi with low signal can caused significant battery heat.

Are you using the phone while it's charging, that tends to heat it also

Relax, there is nothing wrong with your phone. If you play a game or browse flash powered sites, you can cook eggs on the back of your S2! Talk about multitasking phones, who else can cook you breakfast?
Personally, I reduced drastically the heat/power consumption by rooting the phone and removing over 60mb of crap. Now I run at 160mb of memory for services and my battery life easily doubled. It still heats when I charge it for a while... On my old Palm Pre2, after 2hrs of usage my battery was completely drained with similar heat issues.

That is a lot of wakelocks that maps is giving you there man!

Thanks, never thought about it... How do I fix this?

First: HOW HOT is Your hot ? (for an Eskimo 15 °C is already very hot)
Second: Leave it as it is. EVERY ELECTRICAL DEVICE gets hot when used. The more the hotter.
E.g. Laptop core i7 CPUs are designed for max. Heat of 105° C and my Vaio runs at 85°C when CPU is at 100%.

I'm gunna guess........ Latitude? Do you have this enabled? It depends on what you are trying to do, about 25% battery in 5 hours running time isn't too bad or anything, just all of those waking events add up. Also it could be that you are out and about and that your WiFi is constantly searching, that would be my other guess. But maps has already admitted to eating 21% of your charge on your third screenshot

Ya, latitude is on.

Another myth debunked.. "batterystats.bin"

Just ran across this post by Dianne Hackborn, system developer for Android at Google on Google+
I figured it was worth reposting here
"Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away."

I'm in shock.
Why did I read this with my hands down my pants

Doesn't surprise me, considering most on the forum aren't hardware types and/or know how lion batteries behave...

Truthfully, I don't even know what works and what doesn't anymore. My battery is still sucks!

Battery issue

Hi all,
I'm having this strange issue with my Fascinate on Verizon. My phone boots as normal, runs as normal for the whole day, and then all of a sudden I'll go to wake it, and it'll be off. I'll power it back on and it flashes an empty battery screen. The screen doesn't stay on for long, and then it shuts off again. The battery is definitely charged. Any ideas? Is it a bad battery?
Also, if I remove the battery and hold the power button, and then put it back in, it turns back on as normal.

Are you doing any over/underclocking or messing with voltages? Or any kind of task killer type stuff... only thing I can think of off the top of my head

None. It happened on stock as well. There is a thread on it already and it seems nothing came of it other than faulty hardware. It doesn't happen frequently so I guess I can live with it.

What you're describing sounds exactly like a sleep if death (SOD). I believe that's what craw was getting at when asking you about OC/UV. Some apps have been associated with SOD, with 'youmail' being the most notorious. You may want to Google some of the apps you're using to see if they're known culprits, particularly if they're smaller market apps (i.e not popular).

It's totally random when it happens though. And I don't have any apps that are not popular. All of a sudden I'll turn my screen off and it'll happen. It happens maybe once per day. I \never need to plug it in, just pull the battery. No OC or Voltage changes or anything. Totally scratching my head here.

I got this picture from a thread on RootzWiki that is the same issue I am having. When the phone tries to turn on, this screen flashes (without the turning progress wheel) and just repeats until I pull the battery.

I'd try to run the phone with pretty much no apps on it and see if it happens.
Alternatively you can try to find what step is causing the sod (likely 100 or 200mhz step) and increase the voltage a notch. Or just try to run it with 200mhz as the minimum step. If you run 200 MHz and get a sod then bump voltage up a notch on that step.

That's what I'm trying now. Used to be on 100 MHz minimum. Bumped it to 200. Thanks for the advice

Your battery skills are no match for Ingress...

Something really weird happens when playing Ingress the battery drains like a mofo which is expected and then when I stop even when I use the phone the battery stays flat for a while. Seems the power of Ingress is too much for the battery sensor on the phone. Makes it hard to know how much battery I really have though.
I hope they fix this. My SGS3 at least drains fast but normally not over a cliff like this.

My battery has this issue too, it just goes down 10% in a second
Sent from my Nexus 4 using xda app-developers app

its using gps, Accelerometer, gyro, proximity, compass, and all the cores to run so yeah its pretty resource heavy

My battery lasted a whole hour while playing Ingress last time. That's not too bad considering that the screen is on, with gps, etc etc.

I have seen this on any electronic devices, laptops, phones etc. I think it's just a software issue

is it using stock rom and kernel?

Happens on every kernel so I think its a battery controller issue rather than kernel. The funny thing is after I stop it flat lines for a while so it obviously didn't really drain what it shows. Yes it uses basically every part of the phone at once but should be a smooth drop not off a cliff. One time I tried it went from 100% to 10% in like 1.5-2hrs of Ingress.

how long can you play ingress on a battery charge and on what phone. I have SGS2, standar battery and I can reach 2,5 hours of screen on time.
