Black screen during charge - no reboot possible - Sony Xperia XZ1 Compact Questions & Answers

Hi everyone,
I'm coming to you with a random problem which I can't reproduce. Over the 2 past years, I had it about 2 times but I had to wake up at 5 am.....
Here's the explanation :
I'm putting my phone on charge, the alarm (The app AMDroid) is supposed to ring at 5 am but sometimes it doesn't. When i'm finally waking up, I'm finding the phone blocked. Black screen, no sound, no response to physical buttons (volume, power) or fingerprints. I'm forced to reboot it with the volume up + power off keys.
I really don't understand from where comes the problem. I already had when I was using the regular sony alarm app and as I said above I can't reproduce the bug which is kind of embarassing when I have to get up early...
I hope you'll be able to help me,
Thanks !

Bump !

I just had this happen to me this morning, and solved it with the same procedure.
I noticed this morning when I woke up that the device was extremely hot, potentially a temperature failsafe kicked in?
If that were the case, I have no idea what would be causing it. Presumably something has the CPU pegged at max load.
I may try to dig for logs, but I'm not familiar with how to do this on Android.

Hi Telomeres, thanks for your comment !
Two quick questions :
- do you have the fingerprint unlock feature enabled ? (do you have at least one fingerprint recorded)
- si you have the battery maintenance (i don't know the exact name in English) enabled ?
I'm trying to pinpoint the problem, so far i have those only two options..

I do have the fingerprint unlock enabled, despite being the US. My guess was that I was accidentally shipped an international version somehow? I did not go through any measures to enable this on my own.
If you're talking about "battery care" where the device slows down your charge rate to increase longevity, yes I do have that enabled.

Your information about the battery overheating is making me think about the battery care. I don't have regular schedules so this option activates kinda randomly just like the problem pops out.
I'm asking you that about the fingerprint because i saw a thread where someone said the fingerprint sensor was at fault.
Unfortunatly for us, we both have the same settings hahaha

Actually, on checking my settings Battery Care was disabled and I believe that setting persists through reboots. However, I did not have my phone charging overnight. I don't recall what percent my battery level was before bed.

Damn. So close to find a clue !

Happened again overnight last night.
I had battery care enabled this time.

I really don't understand from where comes the problem ; we both have a totally different setup and ways of use/charge our phones :/

I'm having the same issue...... I'll see if I can get get some logs..... I do use battery care and stock alarm..... Twice in the month of October ive nearly been late for work because my phone locks up, charge light remains amber but is full (no excessive heat) and I have to force reboot

I had the same kind of lockup like 5 times now in the last two month. Last lockup was tonight with the September security update.

This happened to my phone twice recently, but my phone was NOT charging.
Last time it happened, I went to bed before midnight, my phone was at about 70% battery, so I decided not to plug it in. I put the phone on a shelf beside my bed and fell asleep.
When I woke up in the morning (I don't use phone alarm, rely on my smartwatch for that), the phone was unresponsive, black screen, needed to long press VolUp + Power buttons to reset it. I'm not sure when I plugged it in - before or after the reset, but the battery was basically flat. I took a screenshot of the battery chart that morning, which seems to tell that the phone has been dead for most of the night. As you can see in the screenshot, the battery line is natural until after midnight and then it's just a straight flat line until the morning. This leads me to think maybe it's a battery problem?

I have Figured out something about loosing signal

If you battery power goes below 50% thats when the problem starts. Is there away to get the right juice to the radio at all times ?

I'm not sure thats actually the case, but perhaps. I may try it.
My battery level has never been below 60% as I am anal about having a charging source near by. The Radio Reset Issue is directly related to certian Programs (or versions thereof) and how they force connections to the internet.
Please anyone reading this. please lets try it out. please post your results back. Lets see if you can still get constant and good signal if your batery is below 50% .
and also if your having battry problems. like your phone sometimes refuses to charge. I think that it could be the battery. please lets all see.
My battery level is currently at a little under 40%. I have a full 5 bars of service and sound quality is the same as if the phone were at 100% (I called my voicemail and a friend to test it out)

Thanks for helping
i never had any problems with the signalstrenght and battery health,
even with 10% or less i still have maximum signal strength..
but i live nearby a cellbroadcast-antenna, so maybe that's why
Here's an update. My battery life is at 29% and still no drop in call quality. I just had a 10 minute convo with somebody and she could hear me perfectly fine.
Thanks. From my observations, at least with me, If your loosing signals and you notice it happens when your battery is below 50%, or sometimes when you try to charge your mda and the battery refuses to charge, Then its the battery.
Get a new battery.
Thanks for those that helped.

Going off the Signal Topic
WONT IT AFFECT BATTERY LIFE?
I mean Li-ion Polymers dont have a memory problems but once in a while u gotta drain them completely.
What u say? Maybe I am wrong

Okay I'll admit that there have been 2 times in the 6 months I've have my phone that my battery accidently went flat but otherwise I can count on one hand the number of time it has been below 60%. I've had it off the charger for hours and my battery is just fine. Even had a two hour call once without being plugged-in using my BT headset. Still plenty of juice when I hung-up the call.
Great !
Dont know where But I read it at the P910 Forum somewhere.
A user had his phone charging on the cradle.
The moment he got a call, he picked up to answer that.
The call lasted for barely 5 mins.
After the call he put it back on the Cradle.(for charging)
SINCE THEN he says" the battery went KAPUT !
He says that an expert told him that he should have waited to Recharge the battery a BIT more than 10-15 mins allowing the batt. to cool down a Bit.
If this si the case None of the MANUALS MENTION THIS EVER and these people do Provide warranties too...
Funny.......

short battery time

I'm using Galaxsy s3 lte with caynogen mod on it.
my problem ocuured before i falshed the Caynogen mod.
As in the title my problem is that I have a short battery life time.
little details about my problem:
- my phone has arrived with a european charger 50 HZ , version is : I9305xxbme1
- the problem started while I was in a trip to taiwan they have American electricity 60 HZ . I was charging my phone for a long while, when the battery was about 5-10 % charged the screen quality was very low, the colors where not sharp at all , and the phone was working slowly. Therefore I took the battery out, it was a little moisty(the phone never touched water or been near them ) so I left it out for the night, then i placed the battery back in my phone and waited for it to go empty, when it did, I charged the battery back to 100% when the phone is turned of, and that solved the sharpen problem of the screen. However, when the phone was getting to about 5-10% it would automaticly shot down after the screen "blinked" and when I hit the turn on button it will not turn on - stuck on the syanogen / samsung boot picture. after charging the phone it would boot normally.
- while being in taiwan my laptop screen also got out of service and was fixed by applying warranty, on the phone i dont have warranty anymore.
that and more , the phone is getting realy warm.
thanks for helpping <3

Perhaps you should try a different kernel like boeffla or agni, to see if the problem persists or try another rom other than CM. Im on liquidsmooth rom with its default kernel and i have to say im very very happy with the battery life, see picture of battery since last charging.

[Q] Poor battery life

Hi!
I've searched the forum but didn't find a straight answer. What's your battery life?
Mine, having no apps, few notifications, black face and always on get just 13h. And that's frustrating. My unit it's just three day's old and if this is the expected performance I will return it at once. What do you think?
Thanks!
I'm getting over 2 full days easy. But I also have enough ambient mode turned off so the screen is completely off, unless I get a notification or am using it.

Just a update before I put my watch on the charger.
2PM on the 19th to 8:35PM on the 21st
I usually get 2-3 days with moderate usage. Always-on screen enabled seems to be about the same as when it is disabled for me so I leave it enabled now. However, my watch screen does shut off from 0000-0650 hrs everyday. If you aren't playing with your watch a lot then 13 hours seems unreasonable.
I just checked mine : 72% remaining after 13 hours. Always on enabled - used lightly (notifications and some small utilities). I'm charging it every evening though .. just to have it 100% in the morning.
Thanks!
After a watch reboot it seems I'm getting a couple of days of battery life. I imagine I had some mysterious app depleting my battery. So I'm keeping the watch.
I have also experienced poor performance of my LG G Watch R. It will drop from 100% to 0% charge in 4-6 hours. When I look at the AndroidWear log, it shows about 15-30% power drop over various applications. I am then questioning where the other 70% power drop has gone.
This is extremely frustrating. When the Bluetooth is off on my phone, the power drop is as expected - a few percent every hour.
Anybody else have this issue? Could it be my phone? I have a Galaxy Note 3 on the Verizon network.
Thanks for any suggestions.
Cheers,
B.D.
Yes, I also had the issue today, already for the 2nd time in the past 2 weeks. Something happens and the battery starts depleting quickly ...
Any idea how can I see which apps have caused this rapid battery drain? Someone mentioned android log ...

I'm getting 2-3 hours of battery life. I've had the watch for less than 24 hours. I realize once an update is done battery life isnt optimal for a day or two on Android but this is nuts. I have screen always off and haven't installed any apps. I'm gonna give it to Monday and If I'm still seeing this drain, It's going back to Google.

I read recently that there is a bug in the battery meter when watch is shipped. It will show 100% then drop very quickly for first few days. I've had mine nearly two weeks and I get through a shift at work (8hrs) with 60%+ remaining. I work nights so I keep brightness set at 1 which probably helps. Hope it gets better after a few cycles.

[Help] Z1 shutting down after bootanimation

Guys, before placing the problem, I want you to know that the Z1 will be around 2 years old in September. The old unit was replaced with the current unit in September 2014. The battery level has been steadily dropping since the last few months. And it is running Stock firmware with NUTs Dual Recovery and Xposed.
Now onto the problem.
The Z1 had been in deep sleep for the last few hours when I unlocked it. I switched on the WiFi, received some notifications and was just going to download an app from the Play Store when I received the message of the kind "The phone is being switched off due to overheating".
Now, it was awake for hardly a minute when this message showed up, and I hadn't even downloaded the app. The battery level was more than 95% and the Z1 switched off, even though the whole phone was ice cold. It wasn't even warm let alone overheated. And in my approx 3 years of owing this phone, i had never got this message, though the Z1 had heated up a lot of times.
Now when I tried switching it on, the Sony logo showed up, then the Powered by Android logo, and then 5-6 seconds of the animation after which it abruptly switched off. This happened every time i tried switching it on.
I then connected it to the wall charger, when the Z1 showed up this message

It doesn't boot up even though it's connected to the wall charger.
My guess is the battery has gone rogue, but then the level isn't dropping either.
Now I don't know what to do, bcoz I have no idea what the problem is.
If any fellow members have gone through a similar problem, help would be greatly appreciated.
Thanks anyways [emoji4]

Never had this message, but I presume this issue is because of what you said: battery has reached it's end. Many people, not just on XDA, have posted various symptoms that their device's battery is failing; the most common one is the device's battery rapidly drops to a certain percent and then abruptly shuts down. Some even claimed their phone never turned back on after their phones shut off. My Z1's battery got bad to the point where the battery started to swell and unseal the back cover of my device. The solution that fixed everyone's problem, including mine, is to replace the battery.
Same problem here...
xperia Z1 C6903, shutdown for "overheating", I think is battery temperature , but not solution found.
* I've changed battery for new one, but problem persist.
* Restored phone with sony PC companion, problem persist.
* Also I've made the HARDWARE FIX
http://forum.xda-developers.com/xperia-z/help/hardware-fix-xperia-z-charging-booting-t2760911
(I think I've put the correct pinpoint )
Same result, no result.
I can see the sony logo, and the boot animation some seconds, then the phone shutdown .
Help would be greatly appreciated.
Thanks anyways

Very high battery drain with 70% CPU usage on idle

Around 3 days ago, my phone has turned from around at least 6 hrs of SoT to around 2-3, even while only leaving it mostly in my pocket. This happened after i factory resetted my phone, for some odd reason. When the CPU usage was usually below 50%, this time it's AT LEAST 70%, often reaching to 100% for no reason. The process "Android System" on the battery usage screen takes up around 40% of my battery drain. I had google assistant at the time, so i thought it was the problem.
I factory resetted my phone again yesterday, and it fixed the problem temporarily. Assistant became now on tap again, and Android system only used up around 8%. But the battery drain just came again when i woke up today.
Does anyone know what CPU process might have been the cause to this problem? Or else I'll just factory reset I guess, but i'm scared it'll happen again and again.
Note: My smartwatch, root, substratum, and KLWP aren't the cause, since last week when I used these things my CPU usage was fine.

Help pls ;-; phone is really unusable for long periods of time
Edit: Got CPU usage down to around 10% most of the time using this APUS Booster app I found, looks shady and bloatware-y as **** but it works i guess. Have to do it everytime i restart phone though
reflash the rom.
I think the problem is with pocket mode \ proximity detection.
Try this experiment:
Cover prox sensor with one palm and try to unlock using the fingerprint scanner. If pocket mode is on, nothing will happen. Phone won't unlock.
Now shift palm covering the prox sensor slightly away and repeat above. At some distance you will be able to unlock phone.
My hypothesis is that if one keeps phone facing the body, pocket mode may not get activated allowing the fingerprint sensor to keep sensing one's body (capacitive) and the phone won't unlock but every movement will keep on making the FP scanner work heating and draining battery.
This did not happen in 7.0. But 7.1.1 update seems to reduced sensitivity of proximity sensor.
Workaround: keep phone in pocket with screen facing away from ones body.
Hope this works.
The proximity sensor works well enough except* it's clearly constantly draining your battery
I'd just turn it off
I don't have 7.1.1 yet so IDK about how the updates have changed things. It works well on 7.0. but clearly that's going to burn a lot more resources than it's worth
