Phone not switching on: Battery and phone very hot - Galaxy S II Q&A, Help & Troubleshooting

Just woke up and my phone is boiling, especially touchscreen and battery. Its not switching on, I left it on charge like I do every night.

Just to let you guts know, never flashed or rooted my s2. Its still on 2.3.4 with kernel 2.6.35

Turn the phone off remove battery and let it go cold .
Then connect to Samsung charger and see what happens .
Problems
One factory reset after backing up data .
Two try a another/new battery
Three return to service .

Try with another battery, I'm pretty sure that that will help

We've had it happen when a app has "hanged" and not closed on Gingerbread. Haven't had it happen yet on ICS *touch wood* .. phone gets hot and huge battery drain quickly.. even while on charge.
Maybe a recent app you have installed has caused the hang?
leaving your battery on charge overnight is NOT the problem

I posted this few days ago, I'm having another problem now, unsure if its linked to this. But occasionally when phone on charge, I'm getting a pop up notification saying 'battery paused, temperature too low or hot'
This happens regardless of the battery or charger. I've taken screen shots of they help. Battery temp is 67 with condition over over heating. How do I solve this

Bump, anyone?

Have you a bumper on the phone or other case protection ?

Depends on which battery I use, if its the official 2000 mah battery then I use a cheap £1 mesh case. If its the standard battery then I don't use any. The extended battery is now charging.
A friend with a phone shop told me to warm the batteries up before putting them on charge and to my surprise its worked, weird since batteries were saying over heating

[Q] Overheating & Phone Stuff!

Gday again guys,
Yesterday, my Nook Overheated and turned off when i picked it up, it was roasting hot and i could barely touch it. I charged it in the morning but when i went to use it at lunch time, it was mega hot and had 8% Battery Left (from a full charge).
Has anyone else had this problem, because i cant imagine it being good for my Nook.
The other question i have, is it possible for us to disable the Phone/Cell roaming & data functions on CM7. I dont see it having much point there, and its only using battery life?
Cheers guys! Steve

thats definitely not normal, i would advise towards going to a b&n store, explain your problem and get a replacement. sounds like a hardware issue rather than software. of course erase everything and revert back to stock before you go to a b&n store.
Sounds like the battery has an internal short. Return

Its never happened before just the other day, my problem is that i dont live anywhere near America! so i can just 'return it'. I am currently working in Egypt, and i live in England which makes things mega hard.
Is there any chance it could just be a one off?
Really?????

Since the standard voltage in Egypt is 220v, are you plugging into that? I'd be suprised if the charger is rated for that.

Stock charger is 100V - 240V, 50Hz/60Hz
One obvious question: Do you have a cover or case for your nook? Some aren't properly vented and can cause overheating.
Yeah dude I have a cover but I don't think that effects it at all. This has only happened once. I think a program malfunctioned and used up loads of CPU which overheated it. Do you guys use any task managers to monitor what's using your CPU/memory.

Restart the phone and suddenly battery has half of the juice!

Hi all, as the description says it's quite weird. While I have let's say 56% battery and for some reason I restart the phone, then suddenly after booting it show I have 18%!!! (screenshot attached)

I have latest 4.0.4 official UK unbranded firmware and it happened on 4.0.3 too. I have tried factory reset and doing a battery cycle.
Could it be a pure battery problem or may it be a bug? Anyone else has this problem?

I also have this problem... It's a huge issue for me! Constantly having to recharge! grrrrrr!
I'm running 4.0.3 UHLPK
Have you tried recharging to 100%, taking battery out for at least 3 mins (180 secs), then allowing full discharge?

Yep tried that. Tried anything I can think of.

It's normal. The fuel guage chip in GSII doesn't need calibration, but the downside is sometimes after rebooting below 60-50% battery it can show wrong battery info.The battery still has power just reporting is wrong. If you wait for sometime you'll see the battery climbing back to pre reboot state.
So DON'T PANIC normal operation.
Restarting the phone resets the fuel gauge. If you leave it for a while, the battery will come back
Thanks for the replies!

Battery question

Hi guys, after a little cruising around the forums I managed to get my galaxy s2 working just how I want! I have a question though... whenever I do a battery pull or restart my phone the battery life shoots down like crazy!? Does anyone else's i777 do this? Is it normal or do I need to fox something. All the roms I have used have this issue for me. I am on CM9 right now. Please share your thoughts! You can see the 2 pulls I did during the day

You should not pull the battery out while the phone is on. Holding the power button for about 20 seconds achieves the same result. Hope this helps

This is something I think all of our phones experience. The way I understand it is a bug in our battery's fuel gauge, the battery level does not actually drop, but the phone just mistakenly reads it that way. I've read a few posts where if you remove your battery for a couple minutes and then charge the phone to a 100% after putting it back in, it recalibrates things. It seems to work for me until I flash other roms, but I cannot confirm 100% if it really does work.
Very true and sometimes its very frustrating to see a drop from 40% to less than 10% right after a reboot.
Will some battery calibrating apps can fix this?

[Q] SII Sever Battery Issues after 4.0.4 and even while phone it is switched off

Most of Galaxy SII users have had good battery backup but not me, my phone once went into a bucket filed with water. Had a friend to open it up and clean it with a chemical (Usually used to clean phones circuits)
The phone was fine, then battery problems came up, changed the battery still has issues average time it lasts is for 8-9 provided i do not use it for anything but 2-3 calls or text. or 3-4 hrs is maximum. All this has happened after 4.0.4 update.

Can anyone please explain what the problem is with this phone. I am not sure if it is a bug/hardware problem. the phone is out of warranty now.
**I am a noob, I do not know how to root a phone however one of my friend helped me root HTC Wildfire which now has EPIC Battery life.
Thank you

it is common when you drop your phone into the water that the battery will start having problems.
For example suddenly you get a drop from100 percent to 50 percent.
I could be wrong, you can check the guide that is in my signature for your battery problems.

The thread is FAB! but like I said I am a noob hence doing everything you suggested is tough for me to understand. Looking at things like removing live wallpapers, stopping auto sync, keeping wifi and data plan off minimum brightness. I have tried it all. Still the problem exists.
Short circuit, perhaps? My suggestion would be to bring it to samsubg and see if they can repair it. I think it's a hardware problem

Seems more like it but they say there is a bug in 4.0.4. Should I try root before handing it over to samsung or just leave it up to them?

I have the stock CM10 rom installed, and it usually does something like this that only lasts for a few days and goes back to normal. But this has lasted for almost a month now. As you can see in the pic, sometimes its says charging but doesn't "gain" energy, and when it does in drains extremely quickly. When it is asleep or turned off it still drains. I tried charging it with a different cord, then with my computer. Then I tried using a GS3 cord & adapter, it charged faster, but I couldn't tell how fast it drained since I wasn't using it.
Do I need to replace the battery? If I do, will it cost a lot, because if it does I'm just going to get a Note or DNA....
Try using a battery calibration app, people say to use it when you flash a new rom. Also, it might be an actual problem with the battery itself. Try getting a replacement battery if so. But then again, before you do that try going to stock and see if the problem is still present.

once it charges I'm going to see if that will help. and my son deleted my stock rom (long story), so I'm stuck on jb/ics.
Also its recommended after you calibrate to drain the battery to 0% and then recharge to 100% afterwards. And as far as the stock rom goes, you can restore using Odin and download mode
