Phone shut down then wouldn't power back up until plugged - Galaxy S II General

Hey guys,
I have had this particular device for about a week... it is a replacement as my last one had a faulty cellular radio. So this is still under free replacement warranty - but I hope it doesn't need it.
Anyway, I was at the pool hall today, and the phone was working ok then one time I pulled it out of my pocket and it was dead... home button did nothing and the power button did nothing. But it had plenty of battery life left (60ish %).
About 10 minutes later I plugged it into the charger and after about 45 seconds it showed the battery charging and all was good. What could have happened?
I keep it in a case (TPU case) so I was guessing overheating but I wasn't really even using it. So I don't see how it could have been that hot.
Edit: also, when hitting the power button it doesn't go from full brightness to screen off and vice versa.... it has like a middle step of going dim first. Then off or on, my last device didn't do this... is it common?
Needless to say I am a little concerned.
Cheers!

Really annoying problem...

Hey guys.
I'm experiencing some problems with my Touch HD. When I get it to start I'm really happy with it and every program runs as it should.
My problem is the battery or something like that. I can have the battery power at 70% one second and the next the phone is telling me to either charge the battery or the device will shut down. I try to start it again but at the start screen it says Battery level to low, your device will shut down.
When I try to charge it the LED under the power button will show a solid amber light, telling me that it's charging, for about 7-9 seconds and after that it will either start flashing between amber and green light or just turn off.
I've tried having it like that over night and try to start the phone in the morning and the same message appear on screen, "Warning! Battery level to low! Your device will shut down!"
Read in some other post about someone who had a similar problem, but not quite the same, and that was resolved by removing the battery, plug in the USB cable for a few seconds, disconnect everything and then put the battery back in and start the phone. This works for me about 30% of the time. When it works the battery shows about 60-80% power.
I've tried a hard reset and I've tried to contact HTC without any success. Any suggestions from you guys, you seem to know almost everything there is to know about these phones.
Thanks.

Have you tried keeping the battery out for a day?
When I got my phone, the first 7 charges I turned the phone off and charged it all the the way up (to get the calibration accurate). Now the battery life is excellent, I can use it for couple of days without charging.
You should try returning the phone, seems it is fine software wise. Can you use the phone with the charger in? If yes, then there is probably something wrong with the battery or the hardware that is interacting with the charging.
I've tried keeping the battery out for about 24 hours but it didn't help. I can't start the phone when I have it plugged to the charger. I'm going to return it today and see if they can just exchange the phone in store or if they need to ship it somewhere to be repaired
Thanks anyway.
Sounds like a defective battery to me...
That's a good idea, better to get a new one.

switch off wifi, install Advanced Config, select all power management enabled
and try again. i also had the situation that my hd took 1550 mA. so the battery was sucked empty within several hours. now everything runs perfect...
Have exactly the same problem
I have exactly the same problem. One moment the phone works and charges fine and the next it shows irratic battery levels and eventually needs to be shut down. Following the shutdown you get the 'Battery level too low' message on startup, right after the Smart Mobility screen. In my case I think the problem mostly started when the phone was either just connected to a PC using the sync cable or when trying to top-up the charge using the wall charger. I also noticed that when the problem appears the plug symbol would appear (indicating it is charging) or sometimes not and then when checking the battery level, the indicators would actually go down sometimes losing 2 or 3 at a time until there is only 1 left and the phone says it needs to shut down. Pluging in the wall charger does not help as the LED indicating the phone is charging only stays on for a few seconds.
Now, I had many trials with removing battery, sim card, memory card or any of those in combination and sometimes these seem to work, but I think the key is the temperature of the phone. Every time I went to the car to drive home, where it was cold, the phone would start charging again, when just before that it would not react to anything all the time I was in the warm office.
I have now contacted HTC and am sending it to their repair centre tomorrow. Hopefully this is recognised as a fault and I will get a replacement. BTW, they arranged for a free courier pickup. Not bad, but the key for me is that the phone is being replaced as I really like the phone.
Update: Got a replacement after 1 week
Got my replacement phone today and hope that this time I have no further problems. I also had to return my previous one with a screen problem (see my post here http://forum.xda-developers.com/showthread.php?t=439410&page=2).
Everything went quite smootly and I liked the offer of a free of charge UPS pickup, so the only complaint I really have is that HTC send me a new phone but no replacement screen protector. Just the original screen sticker (the one with some writing on it) had been stuck on. It was in a bit of state like it had been taken off and put back on several times. I just called them to send me a replacement screen protector, but I don't hold my breath to get one. Probably end up buying it from the website.

Won't boot.

Probably I'm just new, but since after rooting it, it slowly ran out of battery as phones do, but now I'm unable to switch it on. Tried several ideas but to no avail.
I guess it isn't a big deal, I can always return it to the store later today and ask for a replacement since I only bought it last week.
Whilst I'm here, anyone think it's worth dropping this and switching it for another one whilst I'm at it.
Empty battery? Maybe you should charge it for a while.
won't boot
Hi, my dell streak is only three weeks old, but all of a sudden won't boot. Haven't done anything I shouldn't have. Have just downloaded a few apps, was using it at night and woke up in the morning to find it was off and can't be switched on. Took the battery out and put it back on again. Pressed the shutter button along with the power button, and held down the volume keys along with the power button, nothing seems to make a difference. Can someone help please!

try charging it for a while?
Take it back to the store and get a replacement, if its still under warranty.
Hi Guys, thanks for your replies. It's working now, this is what happened:
I woke up in the morning to find my phone switched off and I couldn't switch it on. I connected the main power charger for 5 mins, then laptop for 5 mins to charge but neither helped. The defect I think is in the charger. I left the phone connected to the laptop for a few hours, then switched it on to find it still wouldn't switch on. Then disconnected the sync cable, took the battery out, and put it back in - and voila, it switches on!
Issues: charger failed in two weeks; the streak doesn't switch on when the battery is down even if it's connected to a source of charging (in this case, laptop). Dead battery - charge - take battery out - put it back in - switches on.

Anybody else had this?

Pushed the power button this morning and no response, thought the battery had run right down, so plugged it in and it booted to the dell screen then froze, removed battery and replaced it, booted no problems at all, still 60% battery left
Once, I think it's because the device has flexed or got jolted at some point and the backplate contacts have come apart briefly. The only way to get it to switch on was to remove the battery and refit it.
I've had this too, but not after a jolt or flex - noticed it after waking up on a morning - Streak had been on bedside table with good charge.
I've had this maybe twice since having the device.
edit to add:
The only difference is my device did not freeze on boot.
yep - every time i power it down and leave it for a bit, it will only fire up again if I take the back off, pop the battery out and put it back in.
The LEDs come on, but it goes no further unless I do the above. Annoying but I can live with it for now (not sure what the wear and tear issues could be over the life of the device tho?)
did it on 1.6, still does it on O2 2.1
That's what's i was thinking, that stupid backplate! it may have moved 1mm and caused error
I posted a comment once about supergluing the fu%$er, might try myself.
Yep, sadly had the same problem. The worse thing is it did this the first time I turned it on. Done the same thing again this morning after simply switching it off.
Hopefully it won't be annoying or we will learn how to avoid it - backplate seems to cause the problem but I didn't even drop it or mishandle it in anyway - just merely switched it off and on again...
If the backplate is the problem, I can see it becoming a real issue, mine is definitely a looser fit than it was a month ago.
This just happened to me this morning. I went to bed around 2am with 90% charge and woke up 8am off on totally drained. The phone was lying on the carpeted floor with no movement. Powered back up and on with icons all messed up.
had this couple of times day, not the first by a long shot. its the back plate for sure. it flexes just a tiny bit and thats enough to make it shut down. pretty shoddy design
I really don't see how it could be the cover. Second day in a row I went from full charge to dead when I woke. It was on the floor the whole time and never touched. Then I charged it and the screen would not respond. So I hit power and then it would not come on again until I pulled the battery. Now, I'm just going to try powering down every night. If it's dead I just leave it at home for the day.....such a waste.

Won't turn on D:

So today I left my tablet to charge, it was at like 25% left, while I went to out to my practice. When I returned about 2 hours later, it wouldn't turn on. Before I had left, it was charging so it's not that it ran out of power because the outlet didn't work. I switched the outlets, plugged it into a computer, pressed the power button a bunch of times; nothing. Perhaps I got a defected unit or downloaded a bad app? I don't know :/; ideas?

try holding down the power button for 15 seconds
Hold the power button 15 seconds, let go, then try again for another 7 seconds.
Wow, that actually worked, thank you so much (held it till it turned on, about 10-15 seconds). Would you happen to know why it had just turned off like that? I'm at 81% battery now, so it turned off at some point on its own, and why did I have to do such a long power button press?

i believe there is a sleep mode/lock hiccup sometimes. I experience it with my media dock but not my keyboard dock. its weird and sometimes annoying but not too much to kill my day lol
Yeah this happened to me too. Just a small quirk.
Oh, ok, thanks guys lol I had like freaked out.
I got my Tab yesterday. Used it then set it charging overnight. Won't power on this morning. The back does get warm though. I tried holding down the power button for at least a minute and also tried the 15 then 7 approach. Nothing.
I also tried an idea from a different forum (referencing a Froyo glitch) and tried touching the screen while holding the power button.
Does this sound like a hardware fail?
I had the same problem. Held the power button for 15 seconds and then 7 and nothing happened. Held the power button for a long time. What do I do next?
Mine didnt turn on today. Tried the 15 second press procedure and nothing happened. I grabbed my wall charger and plugged it in and left it sitting there for a minute. I tried the 15 second procedure again and this time the screen lit up and was showing that the battery was charging because it was in red. After about a minute the tab booted itself and all is normal now. I guess my battery went dead since i hadnt charged it and completley turned off my tab. Thats why it rebooted itself. Nothing to worry about.
happened to me too
looks like there is a glitch ... mine was left charging today ... and it did charge but did not want to start... i did leave it on.
I connected to PC and press Power ON + Volume Up + VOlume down all at the same time and it did seem to restart ... worried there is something wrong with it though.
I bought it in USA and Im in UK I wonder if things go wrong if Samsung UK would repair it.
I've had it for about 9 days and have used it every single day. Last night I downloaded 2 movies onto it and everything was fine. Today it would not power on one bit! I charged it over night so the battery shouldn't have drained. I ended up fixing my problem by doing the following:
Held the power button.
At the same time, placed a finger on the screen.
Held it down for 15 seconds or more and it booted up!
Not sure why it only worked when I put my finger on the screen.
I ended up exchanging it either way just in case.

this also happened to me for the first time this morning from leaving it on charge overnight.
however i was able to start it by removing cable and holding power for 15secs.
what could be causing this? I hope it doesn't happen every night.
I had this problem as well a few weeks ago. Samsung sent me a shipping label and told me to ship it back. I got it back in just under 10 days. They never did tell me what was wrong but they shipped back my original Tab.
Guys,
Is this happening when you leave it booted up and charging overnight or is the unit powered off and charging?
I will say that this issue has only happened to me one time and it happened under the following conditions (Ive had a Tab sense launch day):
- Battery was at 35%.
- While booted, I plugged it in to charge overnight.
- The next day at 09:00 I attempted to use it and had to hold the power button for 15 sec to get it to boot.
So, It *might* only happen if its booted with low battery and you charge it overnight. Powering it off and charging doesnt appear to cause it at all in my case.
Yes it happened while powered on and left to charge overnight. Battery was probably around 30-40% as you said.
Still doesn't explain why it would happen regardless of the % of battery left. Hence the reason it's meant to be charging.
I've had it happen very quickly. High level of charge, plug it in, walk off, come back, unplug, and it's dead, need the 15 second press to power back on.
Not a huge deal, but annoying. And a bit scary, since mine went into the "sleep of death" once already, took four days for the battery to drain enough to break the nvflash loop it was in.

[Q] Help, Blank Screen, Backlight on, no picture

Pretty self explanatory. It was dead for a couple of days, I put it on the charger for almost the whole day, now I get no picture, but the backlight is on when I hold the power down a minute. I bought it at walmart, doubt I have the receipt, and didn't get any extended warranty. Is there a way to fix this issue?
I've got the same issue. I was playing Tupsu, when suddenly my n7 rebooted and there was no picture, just semi-strong backlight. When the tablet died, the battery was about 45-50% and I was charging it through notebook's usb port (original n7 cable). I tried to turn it off, but pressing and holding the power button only made it reboot once again (i assume it was rebooting, since the backlight was turning off and on in a second). I've tried it many times, with tablet plugged into wall/usb charger, and even with the power+volume up/down combination, it would still behave the same way. However sometimes after rebooting there was not only backlight, but also thin, mostly white, horizontal lines, appearing in random places of the screen (appearing and disappearing after like 50-100 ms). It would stop only after a reboot, and happened every 5-10 reboots.
I've decided to let the battery die to see if it changes something, and as you may guess - it didn't. It died estimately after 2 or 3 hours. Now it's all the same, except for when I plug it to the charger, there's only a very low backlight (still no picture) and it's blinking... It also makes this continuous "electricity-related" (sorry, I don't know what's the word to call it ) sound. After I press the power on, or let it charge for 1-2 minutes it boots up, and there's just a semi-strong backlight, like earlier.
It's a refurbished 8gb n7, which I got 5 days ago from the polish Asus online store. Oh, and the speakers weren't 100% fine, if it changes something. They were fine at first, but after i plugged headphones in and out, they were making cracking sounds when the volume was over 50% or something like that. Is there any hope I can fix it myself?
edit: the android ver. is 4.2.2, not rooted
the device is getting warm on the left side when being charged, or just turned on...
Have you tried pulling the battery for a couple of minutes?
Sent from my Nexus 7 using Tapatalk HD
Nope, i don't want to mess with the hardware since i've bought it only few days ago... I'm afraid it may leave some traces of being opened, i'm not willing to take the risk.
You won't leave a trace pulling the battery. Just use a guitar pick or credit card and run it round, the back comes off very easily.
Sent from my GT-I9000 using Tapatalk 2
Yeah that is definitely worth a shot. Just pull the battery.
Ok, I did it.
Didn't change a thing >:[
btw. I didn't actually pulled off the battery, i've just disconnected it - it doesn't make a difference, does it? and another thing - the backlight was turning on immediately after connecting the battery... with these randomly popping horizontal lines.
I've got this too!

I've got this too! Pulling the battery does nothing. Last time it just fixed itself, now nothing.
Worried I'll have to take mine back.
How did that 'fixing itself' happened to you if i may ask? And how long did it last?
Your tablet has gone into sleep mode to protect the battery from further damage due to its low level of charge. What you're seeing is by design, as complete discharge of a lithium based battery is bad for it. You should never, ever, let it sit dead for a couple days. If you do discharge it to the point of shutdown again, immediately put some sort of charge on it, as waiting to long will cause the battery's protection circuit to fail completely. Best practice is to not let your device go to the point of shutdown, but rather to plug it in when not in use. Your battery will have a longer lifespan.
Plug your N7 into the charger and immediately press power and volume down to get into the bootloader. Once there, use the volume key to scroll to Power Off Device and then press the power button. After it powers off, unplug it and then plug it back in. It should then charge normally.
You seem not to have read my posts at all. When it happened, the battery was about 45-50% and it was plugged into the laptop's usb port. It suddenly rebooted and there was no more picture, just the backlight - and it lasted for like 2-3 hours (maybe even longer)! Can a completely discharged battery power the backlight for this long? After it turned off at last, i put it on charge and i've tried the power+volume method and it didn't do anything (btw. i already wrote about it)... then i let it charge for like 5-6 hours and it didn't change anything except for the fact, that the battery was evidently charged, because the backlight again lasted for few hours.

Actually, I was addressing the OP without realizing that this was a zombie thread.
To answer your question though... yes, when in sleep mode the battery can still turn on the backlight and keep it powered for some time due to the low power requirement of a black screen. Many users that have found themselves in sleep mode actually have their tablets enter into a prolonged cycle of bootloops. From the sounds of it, your device seems to have, for reasons unknown, put itself to sleep.
Anyway, I digress... I know you've stated you've tried various combinations of the power and volume keys. Have you attempted holding all three buttons for approximately 30-40 seconds while the tablet is plugged in? If it that will force it into the bootloader, you can follow the steps that I posted to get it up and running again. If not, then it seems your best available option is to seek an RMA from ASUS. Given your speaker issue, I'd send it back regardless- you shouldn't be expected to deal with battery and speaker issues after only five days.

Yep. Many times. And even longer than a minute.
Anyway, I'm going to contact their crappy support. Thanks everyone for trying to help.
