Unusual battery drop. Will not charge or change battery from 20%. Phone unresponsive. - Xperia Z5 Compact Q&A, Help & Troubleshooting

Long story short. Another Z compact down. This time it's my Z5C.
Unrooted Z5C E5823. I flashed some marshmallow from xperifirm (build 32.2.A.5.11) some 8 months ago...
Description of events:
Just finished texting. Turned screen off. I go to turn it on again but the phone turned off, because pressing the power button doesn't do jack. Long press it and doesn't turn on.
... great.
Volume down + power button and it turns on after 3 vibrates. Battery level plummeted from ~70% to 20%. So I just put it on a wall charger and wait.
Some 20 minutes later, I'm surprised to see that the phone is still at 20%. So at this point I'm sure something is very wrong and I start browsing for solutions. Nothing worked.
The only thing I didn't do is a factory reset. But I seriously doubt it's a software problem.
So I say "screw it" and I unplug it from the charger and start using it normally. At some point the phone turns off on itself so I have to do the volume down + power button combo again. But this time, alas, it doesn't work either. So I try the little yellow "off" button on the SD bay + holding power button. This time the phone vibrates 3 times. Then I turn he phone on again. But this time it turns off after some 40 seconds. Then it began a short power on/off cycle and then remained off. Won't turn on. Like if it was hard bricked. I fiddled with the yellow off button while plugged in on the charger and it turned on again but still won't go past or below 20%. Ever.
I remove it from the charger and go home from work. Phone is unresponsive. PC doesn't recognize it. No key combination works. Charger and key combinations don't do jack. But THEN out of the blue, I sense 3 very faint vibrations (i just kept trying to power it on, I wasn't giving up ) and now the phone is on again. Battery at 20%, obviously. Service menu doesn't have a battery test anymore. How convenient... Battery usage menu is always the same when I turn it on. PAst history is gone, app % use are all the same ratios.
I'm trying to backup my data now. But at the meantime. Phone is on and still stuck at 20%.
So, is the battery dead? Wth is going on?

i have smailer problem
my phone wont pass the 90% . also after factory rest (stock rom\kernel\no root\lockedBT)
still, im not sure 100% is my batt i think is started from android 6 (now im at 7)
also my phone wont pass some voltage also (4.300) was 4.350 when the phone was new with 5.1.1
but in QC2 quick charger its 4.308volt max with 92% so i dont know whats goin on:|

hi,
I had same problem somes weeks ago.
try flash new rom, phone stuck at 20% but seems to have same battery's autonomy .
after a week I changed the battery, now all works fine
I think this is the lithium controller that is dead not the battery itself .

Battery and turn off problem
My Device have charge (50,60,70 or more), unnexpected it show 0% and turn off.
Hardware problem maybe ???

[Q] Power light going *blink* *blink* *LongPause* (Archos 101)

I'm at a bit of a loss here..
Instead of powering on, the battery light goes *blink* *blink* *LongPause* ..
I have a (3 day old) Archos 101 and updated to the most recent software when it I first powered up the device. I probably drained my battery yesterday when I put it in the night stand drawer while Aldiko was trying to import a fresh ePub file..
When I turned it on this morning, it blinked once and stopped. When I plugged in the charger (figuring the battery was drained) the "blink blink longpause" started. Long pressing the power button stops the blinking. If the power is connected, the power light burns, so I figure its charging. If its not on power, the power light doesnt burn. I tried the "Hold + while powering up" to boot into recovery but that doesnt change anything.
The Archos FAQ said something about charging the battery, but its been charging for about 9 hours now and the device still wont turn on.. (Green light still burns continuously while charging, not when disconnected) My XDA forums search didnt turn up any results..
Anyone got a clue what this means, what I can do or whatever? Tnx
Maybe the screen froze. Try resetting it by holding down the power button for ten seconds or so. If you're charging it at the same time, it should boot right back up after the reset is complete.

Yes, I tried that :/ That's what I meant by long pressing the power button. It changes the blinking pattern to just the burning power led..
Thanks for the tip though!

Give it another shot. Disconnect the plug. Hold down the power button for a little over 10 seconds. I would do like 15 in my head. Wait a few seconds after that and press the power button quickly once. If you get the steady green light just wait. Dont keep pressing it. You should eventually see the Archos splashscreen. I have had this happen on several occassions when the system has been idle for a while with the screen off. Hope it works.
Ok; I did that.
Except that when I push the power button that last time to have it boot up; the power light just flashes once. I didnt touch it to be sure and it doesnt start.
When I plugged in the power supply after that, the *blink blink longpause* resumed.
When I hold down the power btn now, it reverts to continuous burning green power led.
Its been charging for more than 24 hours now.
This sounds like what happened to mine. it happened after about 3 days, too. I finally got my replacement the Tuesday before Christmas.
If you get it powered up, get your stuff off & clean up your personal info (something I wasn't able to do.
From my post on AchosFans Forum:
For several days my Archos wouldn't take a charge. I didn't think anything about it the first day...stuff happens. After using it the next time, not really thinking there was a problem I plugged it in (and of course it turned itself on again). So this morning it only had 8%. I messed around a few minutes before work resetting it & such - checked setting>about>battery stats and it said "charging" and 0% battery. When I came home this evening it still said "charging" & 0% battery. It then shut down (with a not-normal screen flicker) the first time I unplugged it (hoping to cycle it or get lucky) and it is now a brick. When I plug it in now the charging light did a fast-double-blink and it it remained dead.
I called Archos & they told me to send it back. She didn't ask for much info before telling me to send it, which I took to mean that it is a known issue.
Same happened to me
The same has happened to me after the archos 101 drained its battery fully. I think the firmware has a flaw where it lets the archos drain its battery too far. In that state, hooking it up to the charger wont make it start charging all the time.
I had the blink-blink-blink problem also, even after it had been on the charger for hours. Finally it started working (and charging! )again after lots of 15-second Powerbutton presses, some in combination with Volume Up or Volume Down, and some with and some without the charger connected. Suddenly it turned on (showing 0% charge in the Settings, Information panel indicating it had fully drained and hadn't been charging in the previous hours) . I advice you to keep trying pressing the Power button 15 seconds with the charger connected, and experiment with pressing it in combination with the volume button, followed by a short Power press to boor the Archos.
In the mean time (till a new firmware comes), i make a habit of not fully draining the Archos (i will install Tasker to let it shutdown at 10%) , and checking if the green led comes on after plugging in the charger. Only when the green led is on, it's really charging. And it should start blinking after a few hours to indicate its full.
My wife has a chinese android iPad clone (a Flytouch II) and guess what? It's also picky at charging and turning on.
The Gravity reply had me scared (tnx though) but I'm glad to report that pwhooftman's post helped!
I plugged it in, put a movie on and started trying to reset/start it. It happened reasonably quickly after that.. I pressed the power button while it was off power, the power led flashed once as before. I plugged in the power. The green light lighted up. I pushed the power and + for 15 seconds, and pressed the power button once shortly. Unlike the other times, the blinking pattern didnt start and the green light kept burning. Hopeful, I put it down and waited - as the FAQ said it would start when it d charged more. Finally after a while, I pressed the power button and it booted. Not exactly exact science, but Im just happy that it works again :/
I guess the "blink blink longpause" means something like "I know I've got power but I cant seem to load my battery" - Archos should have this info in their manuals.
Thanks guys

Nice to know I can scare people...and it isn't Halloween!
I tried everything I could think of to get it to take a charge, with no luck. The problem I had with mine was the times it wouldn't take a charge BEFORE I had drained it - that is why it got drained in the first place.
I hope it was only mine!
He s at it again. Drained to 3% and now it wont charge anymore. *sigh*
except he wont even do the blinking anymore now.
Seems to be a fairly common issue with these tablets :/
Same thing was happening to me too. Dunno if this will work for people, but here is how I fixed mine.
Hold your finger on the power button for 10 seconds while the blinky light is on. This should stop the light completely.
Then plug the charger in. This gave me a continuous light rather than a blinky light. Leave it like that for a couple of hours and then try powering it on again.
Hope this works for others.
Had this happen to me once so far. Seems to have to do with it going into a sleep state or something. If I leave it for long and the screen turns off. Sometimes it won't come back up without first holding down the power to shut it down (even though I can't see anything on the screen) and then waiting to boot back up. I had to plug it in, get the steady light and then power on and it worked.
OK, I know this sounds weird...
But what's the temperature of the A101 like?
I had an identical problem a short while ago, and a forum post suggested that the tablet could be too cold. I thought it was a total shot in the dark, but I wrapped the Archos in a quilt for a few minutes, and amazingly enough, it popped back into life with the charger plugged in, and has been pretty fine since then.
To be fair, it could be one of three things: (i) temperature is the issue, (ii) coincidence, (iii) a bad connection in the pins/socket of the adapter input on the Archos 101 which just needs 'jiggling.'
I have also noticed that if I charge the Archos while it is in standby, I never get more than 92-94% battery. If I shut it down, plug in, then shut it down again when it restarts on power supply insertion, I can usually get 98% battery, at the least, sometimes 100% battery.
I agree, we shouldn't have 'quirky' devices, or have to wait for firmware to fix them, but other device makers have had similar problems in the past with battery reporting, until appropriate firmware fixes.
it happened to me last night frustrated the heck out of me couldn't get it to turn on no matter what i did, so i took it back to pc world and the guy said
"what would you like to do, out of curiosity do you like it?" I replied no and he said "then ill refund you"
i then paid the extra on a galaxy tab and not looking back the archos was a complete pile of sh!te! I almost cried when i turned it on and spent the next two months convincing myself i actually liked it.
its woefully made, cheap and tacky, screen is pathetic and the memory appalling.
i know its cheaper than tab and iphone but for 270 it should still be fit for purpose and this is not it's the worst gadget ive ever owned by a long long shot, i didn't even show it off at work because i was so embarrassed at how bad it was.

So, how did the story end?!? Did it survive?
Ok...
I kid you not, i've tried warming the archos up with a hot water bottle for several seconds and that did the trick appearently...
Had the same problem.

HERE is the FIX ! I am on my second A-70/250 - my wife has the 8gb version, and I thought the 250gb one was simply defective - evidently, this IS a known issue, but it can be fixed, and I sent back my other one without reason
Anyways, no more pity party for me, here is the fix - if you have the flashy-power light dealio going on, plug your Archos into the power adapter, plug the adapter into the wall, and plug in the USB CABLE to the Archos, and to your PC - the Archos WILL pwoer up, when it does, it asks if you wish to mount the USB to copy files, select, "YES" and let it sit and charge ! Now - the REASON it does this is VERY simple, and it kills me to admit that I was killing my tablet all by myself ! Disable the "never off" screen thingy - set it for 10 minutes - (settings - display - screen timeout). Go into your power settings as well - (settings - power management) and make sure there is a checkmark in the deep sleep area ! THAT IS IT ! You are fixed ! Dang... I REALLY wish I would have found all this out before I returned the other one - I had SO much stuff loaded on it ! GAH !! - SenKat !
I got the same problem yesterday, it kept blink blink and could not turn on. After 5 hour charging, I warmed it up by hair dryer and suddenly it's on. Crazy amazing! Hahahahahuahuahuahua.
Temperature is main problem. Try with your hair dryer!!! Heheheheheh
Its sounds unbelievable, but low temperatures are indeed a cause.

Prime shut off and wont turn on

I was reading a comic (Akira) and the prime's screen just went black... I just charged it last night and battery was well over 50% when it turned off. I tried the power button, power + volume down, power + volume up, power + up & down and also the reset button... nothing, not even a vibration or a polite F**k You across the screen. Any ideas?
Edit: So just got home and plugged it in - Viola, it kicked on for a second flashed the low battery symbol and is now charging. so it must be mis-reporting the battery level or something?
I have had this happen on a couple of occasions. The first time I did as you did and plugged it in to reboot. The other time I held the power button down for something like 10-30 seconds and it powered back up.
Same here. I had it yesterday.. hold the powerbutton for about 20 seconds and it will boot.
No idea why the Prime is having this behaviour. Happens to me once every 2 weeks.

Same problem happened today - shut off
Hi
Just thought I'd add my comments as well.
Last night I fully recharged my Prime so keyboard and tablet were at 100% charge; this was completed about 6pm and I shut down the system for the whole night.
I then went out for the night.
Came to switch the unit on this morning, held the button for 2 secs and got the vibration you usually get, but system didn't switch on; screen stayed completely black, not even a feint black glow where you know the screen is black but its being powered...nothing.
Tried turning on again, with tablet attatched and detached..but still nothing, not even the vibrate.
Plugged the unit connected together into the mains and the charge lights came on...Orange...meaning charge was required. Triecswitching on and got the screen to disply the low battery charge graphic, then the screen turned off.
After 5 mins of charging, tried to start machine and it started fine.
Both batteries were dead though and needed charging. Its now been on charge for an hour and the tablet is charged to 33% and the keyboard is at 11%, so its looking ok on charging.
Thought it was a glitch, but looks like others are having similiar problems; just wanted to post my problem as well in case this becomes pandemic for Prime users.

S3 suddenly wont turn on, bottom lights and charging led work

Hi All,
I was out a couple of days back and my battery died. No trouble, come back home and charge it up. Worth noting that in recent months battery performance has been poor with a full charge only lasting about 8hours or so. I put this down to a new ROM I flashed as well as natural deterioration (18 month old S3).
Plug into the wall, red charging LED comes on, but the battery splash screen does not. Tried another charger...same. Thinking nothing of it I go to bed and wake up next morning to be greeted by a green charging LED. However, still no battery splash screen. I try to boot...it doesn't. When I "power on" the bottom LED buttons do light up white and go off after a few seconds. When I press the hold button again, they also come on for a few seconds. If i press the hold button while the button LEDs are on, they go off.
This makes me think the screen has broken as both the hold button and the charging LED is doing what it would do...but without any screen activity. However, it was not dropped or put under any pressure in any way. I have opened it up and also made sure the ribbon is undamaged and connected properly. I have tried calling the phone to no avail. It also does not vibrate or make any noises. Perhaps the battery doesn't have enough juice? Its as if its on the battery splash screen, I just cant see it.
I should mention the screen is infact cracked from an incident about 6-8 months ago. It was however, fully functional. Presumably, this will unfortunately stop me from sending it in. It was also using a flashed rom (CM11) and a flashed kernal (Boeffla).
I used a multimeter and measured 3.96v across the battery so that's fine. I can't test the current as I cant break into the S3 circuit and I dont have a resistor on hand to put some load on it.
Next steps?

Try to put it in odin mode (power+vol down+home then press vol up to agree that you are now in odin mode). You should see it in odin.
If you dont see it, your battery or energy system of your phone is broken. Otherwise your screen is probably broken?.

I've managed to get it into download mode and too show up in odin. I can also get it to show the files in Windows if i wait after holding the power button.
This all indicates it is in fact booting up and the screen is broken...
...BUT...no sound...no vibration...and no calls received
Its as if its only half on. Beginning to suspect a catastophic motherboard failure. Is it possible the battery is at fault? Its as if a whole power rail providing for the phone receiver, loudspeaker, vibrator and screen has gone.

[Q] Sleep of death (won't turn on)?

Anyone getting the sleep of death on their XTZ2? I'm running completely stock (not even rooted) on 23.0.1.A.4.30 and just experienced the unit not turning on at all until I do power + up volume.
Upon returning to life, the battery was 90%, so it wasn't battery.
Had a bit of a panic attack until I googled the solution (power + up) but this is the first time its happened to my unit, could it be related to the recent upgrade to 23.0.1.A.4.30? Anyone else seen this?
Mine lasted a day and a half after the 23.0.1.A.4.30 update and then became very erratic and kept forgetting wifi login info.
Did a restart and certainly got a sleep of death OK.
Would not switch on at all.
No power + vol up or attempt at repair via PC Companion made any difference to it.
Since gone back to Sony for repair, that was weeks ago, who knows if /when they will return it.
I had the same problem with mine as well I have the 561 the Verizon model. I have received a replacement but have not been able to get it to turn on either. It shows no signs off life at all not even when connected to power AC or PC. My old one would blink red and go dead when connected to a PC but this one doesn't even do that. I haven't had time to call for another replacement yet but really two defective devices in a row the second one didn't turn once.
Finally got mine back from Sony repair agent.
Worked fine for 3 days, then failed to power on again as per original fault.
Once again returned it for repair.
Think I'll give up and buy an iPad instead - at least they seem to be reliable and consistent.
This just happened to my tablet this morning. Tried all options under the sun but can't get it to boot.
I can't even do a factory reset and I don't particularly want to return it under warranty.... :'(
Mine is an xperia z2 tablet sgp561 (USA Verizon) build 17.1.D.0.437, stock 4.4.2. This issue happened to me 5 days ago after I powered off the tablet, it won't turn on again. Battery charge was ~70% at the time. Plugging it with factory Sony usb charger won't do anything, charging status LED remained Off, power button unresponsive. I let the tablet sit for 2 days without charging cable connected hoping the battery will drain completely by itself and the buggy firmware will restart executing at its base address getting out of the bug. Then I connected the crap to a fully charged 15000mah Anker power pack and alas, the charging status LED glowed red and after ~5 more minutes the LCD screen turned On for ~5 seconds showing a big battery icon at the center of the screen indicating 0% charge. Waited about 1 more hour and the charging status LED turned amber. This time I did the "power button + volume up" ritual holding both buttons for 10 sec+, expecting 3 vibrations but didn't feel any. At this point the tablet is still powered off. Because LED = amber, thinking battery must be at least 10% charged by now, just pressed the power button for ~2 sec and surprisingly the normal power On vibration came followed by Sony logo on LCD screen and the rest is normalcy.
From what I can remember, the recent change I made before this problem happened was turning Stamina to On in the battery settings (factory default is Off). I reset all settings back to factory defaults and so far so good.
Finally got mine back from Sony repair agent after about 3 week wait.
Seems to work OK now, fingers crossed it will keep working this time.
The note that came with the return indicated that they replaced the mainboard and battery, which is a better solution than their first attempt which was just to reflash the software.

Dude same thing, WTF is going on, I tried plugging it into charger, nothing. And once I got the msg of red colour battery icon and then I plugged it in. then it started charging and I was happy so I turned it on the it wasn't charging,
Please update me what happened and what they are saying cause I am about to send mine to get it fixed.
Edit: seems that by replacing the battery and mainboard has actually fixed the issue? Guess it's time to send it back to them, Gosh

Did this method work for you? Plus did you come across like it was charging but it wasn't really charging,(like it showed the low battery stat with orange/red colour LED notification but suddenly it vanishes) then it's not responding at all.??
I had this issue 2 times with months in between , no response from power+vol up , no lights when charging , no response from pressing on the red button behind the flaps.
The last time it happened i tried putting it on the charger for a whole day with no result, then decided to let it rest a few days first , since someone had the same issue and it magically came back to life when he got back from a vacation.
So i try to turn it on 2 days later and the tablet to my surprise responds again with blinking red LED, recharching afterwards did the trick and worked again since
In my case i was running CM11 at the time, both times it happened after an update which required a reboot while, still mistified about the cause and the fix , i presume it solved itself by letting the battery drain.
Since then i reverted to stock rom just to be save but havent had it happen since, this also seems to have fixed some touchscreen problems i was having at times.
Hope this helps.
Bloody hell, I've just ordered mine today!
Don't stress. Mine got repaired. if it goes tits up that's what warranty is for
What did Fonebiz indicate was wrong with your Z2.?
They replaced the motherboard in mine.
Exactly the same, works fine now
This just happened to me today. So seems like overall suggestion is to try and let it discharge. The try to start it back up and charge it then. Just want to make sure that's the only potential solution now?
No! Leave it powered off, put in on a known good charger for at least 12 hrs. Don't touch it in that time.
If it does not come alive after that, send it in for repair.
ok..let me try that. I originally tried that and nothing occurred. However, I just found the OEM charger and usb cable and will try that. Unfortunately it's a Verizon version so sending it in will not be covered by Sony warranty. Per the Customer Service that I called.
ok..tried another charger and the red light came on, but it's been over 12 hours and still no go. I did notice that the red light was no longer on (from overnight charging). I left it unplugged for a bit and reconnected. The red light came back on but still no response. Sounds like i'll need to send in?
Looks like it.
Had the same problem on tuesday. Impossible to switch on, no light, none effect with charger, none effect when connected to PC/MAC etc...
After 4 days without charging my Z2, it came back to life, showing only a big red battery icon when pushing some seconds on the power button. Connected to a charger the red led indicator glowed ! (red battery icon is totally different with the original icon when tablet is charging in power off mode)
After a full battery charge with OEM charger and after a normal power on, my Z2 is now perfectly functionnal.

My S7+ is battery is dead and won't charge anymore

Yesterday somehow my S7+ completely discharged and I am unable to recharge it. I have left it on the stock charger for 12 hours with no result.
Pressing the power button and volume up button for two minutes results in nothing.
What else can I try to revivie my S7+?
Microburst charges.
This has happened to me as well. What works for me is quickly plugging and unplugging the charger. After about 10 minutes of doing this, try powering it up while plugged in. It may or may not start. If it does, turn the screen off immediately and dont touch it. If it doesnt turn on, keep trying.
This did not work either. I sent it to Samsung for repair today.
