My battery life keeps bouncing between 1%, 50% and 100% and doesn't show anything else, you can be looking at the screen and you randomly see it flick between all three values and even more weird, the battery menu is no longer listed in the settings menu and I have no way of knowing what amount of charge my battery actually has.
This morning the phone went off saying low battery (whilst also saying 100%) and when I turn it back on it shows the low battery symbol in the centre of the screen and does not boot-up, great, the battery must be dead. I put the charger in and the red LED light comes on and battery low indicator come on for two seconds, then switch off and endless repeats no matter what I do..
I left it for an hour doing that and turned it on and used the phone for 30 minutes without any problem, then it turned itself off saying low battery, and started doing another loop of the low battery and red light in standby mode round and round again even though it wasn't plugged into anything. I pressed the reset button and after that I couldn't turn on as just a standard, battery low message.
I did a repair of the phone, which surprisingly was able to be carried out despite the fact that the phone wouldn't turn on because of "low battery" before I did it (which makes me doubt it is low) and the moment I turned the phone on after the repair it was still "Low Battery" and refused to turn on, which is somewhat strange bearing in mind it clearly had enough battery for a repair.
I left it for 4 hours charging and I turned the phone on and it operated for an hour in a factory reset mode no problem, however the indicator cycling was still going on. I plugged the charger in and the sound for charging was made, but the phone showed as not charging, despite the fact it made the sound that it is (I think it is actually charging but nothing to indicate ti is)
Again I go into settings and there is no battery menu there, if I search for it using the hourglass it tells me no battery data is avaliable. I search for Stamina mode and put it in Stamina mode and it refuses because just when I hit it, the battery reader says 1% and it says battery is too low. With some good timing I manage to press Stamina mode when it was on 100% and now it's in Stamina mode with 942 hours remaining,, the phone has been on for 3 hours now and now says 950 hours remaining.
Meanwhile the battery gauge continues to cycle 1%/50%/100% all of the time.
Has anyone seen this before?
I did not have this exact same issue, but Battery menu disappeared and battery would mostly show 50% (and very rarely the real data).
Got my battery exchanged now, everything back to normal now. Might be Sony used crappy batteries (though as long as they don't explode I'm somewhat happy).
I sent it back to Sony and I am now am about to go into a third week with no phone.
For the last week they have been waiting for stock to exchange the phone, since they have no stock (no joke) I am still waiting and they cannot tell me when they will get stock.
The fact a mobile phone company have no stock of phones, is pretty funny.

My phone is discharging even when is turned off!
Besides it have high battery drain compared to my BravoC, which in stand by last for days.
This Inspire 4G last max 15 hours, changed the radio, and flashed it to reach that, before it lasted ~9 hours max. I'm talking in stand by, not even using it nor data/wifi/gps turned on. I have checked the processor use and it was in deepsleep most of the time.
Yesterday I fully charged it and inmediately turned it off. Today I tried to turn it on but is dead, completely drained. The battery is new and it does have the sufficient capacity, i mean is not a battery failure (checked it with a hobby charger).
I bought the phone on ebay, it has the volume up button dead, so I dissasembly it to if it can be fixed easily and found out that the phone was previously open. Also the screen seems to be a replacemente (a crappy one) since the light bleed in the dark state is high, alsio the light bleed at high angles. This would explain the high drain using it, but not the drain when is turned off.
Anyone have any idea of what it may be? maybe something not connected properly when it was repaired before or a short circuit anywhere?? or is a deeper failure and there's nothing that can be done?
I'm saving for a One X in the meanwhile but i'd like to fox this in the meanwhile since i won't be buying it anytime soon
So for several weeks I had that - my phone heated up very fast, and very hot, in fact, even when charging the battery would deplete if my phone was in use (but if I left it on low power usage it's battery precent did go up). The battery is fixed.
A few minutes ago, I was on 1%, which happens to me a lot, I watch youtube videos, my battery goes below 15%, and I connect my phone so it charges, but the battery keeps emptying until it shuts down (it says 0% as it's shutting down) and then it starts charging "turned off" from "0%". So this time, my phone didn't get into charging mode, when I tried to turn it on, it didn't even give me the indication that my battery is too low to start android.
Right now it is unplugged, turned off. I'm about to sleep, should I leave it plugged for the night or let it stay unplugged? Is my phone hard bricked? It shows no signs of anything. (I'm on my laptop).
I did switch ROMs, long ago, but that didn't cause any problems, the battery problems were from almost the first week (when I still used the original ROM), but it doesn't make sense to me that it suddenly hard bricks when it's battery says to reach 0%. When it shutted down it turned off by android, not instantly (it turned off as if you would shut it down from the power menu), so I wasn't worried.
I just had my Xperia Z5's battery replaced due to it bloating up. After two weeks, I noticed that the battery indicator isn't working properly.
It would go down from 100% really fast (even during standby - not using the phone) but stay around 30% down for a really long time. No difference in usage. Then it also started restarting on its own even during standby. I would check my phone and it would need me to input my pin saying its required after a restart. Another instance, I was still typing out a text message and it restarted on its own. The battery was around 60% before it restarted but after it turns on again the battery indicator showed that its at 40 something %. I don't think the battery would drain that much just from restarting.
Also, just today, it won't charge properly anymore. It will detect the charger, like it would make the sound when you plug it in but the battery icon won't change to the charging icon and the battery will continue to drain. When turned off, it would show the Sony logo then battery level on the screen but will stay at 0% or whatever % it was left at and will continue draining.
So my phone just died earlier and I just went to plug it in hoping it would still work. The battery was stuck at 0% for the longest time so I just went and left it for a few hours. Coming back to it, I noticed that the LED indicator is green. I pressed the power button and it showed 100%, then I tried turning on the phone. It still turned on, showing 100% on the battery icon and could be used like usual.
I can still use the phone, barely, but this issue is really annoying. I'm not even sure if the next time it drains it would charge again.
So far, I've tried:
using a different cable and charger
doing a factory reset
doing a repair via Xperia Companion
But the issue still persists...
Is there anything else I can do on my end to fix this?
You should replace your battery
Hello.
I'm sorry to hear that your Xperia Z5 got this problem.
Here're some personal experiences:
1.Just replace a battery for it.My Xperia Z5 had same issue last month:Its battery lasts for only 2 or 3 hours,and charges much faster than before.Then I think maybe the battery life loss too much,so I bought a battery from taobao(A Chinese Website),then everything's fine just as when I buy it.
2.According to your description,maybe the sub board(It's responsible for charging and data transmission)is broken too.You can find a used one at ebay.
That's all.I hope this message can help you.And...I'm a Chinese so maybe you can't understand my Chinglish(It means "Chinese English" )...Sorry for that.
Hi everyone,
I have a Leagoo T5c with a more-or-less 3,000 mAh non-removable battery, and for the past few month, battery life has been somewhat erratic. The phone would go from, say, 50% to 10% battery in no time, and I would get the low battery warning, but at other times it could hold at around 45% for a while before really going down for good.
Last night around 8pm my time, the phone went completely dead while the battery indicator in the task bar said I still had about 65% left.
I tried what's described here and there as battery calibration: I left the phone turned off, patiently waited a couple hours (yes, yes, that long) for the battery to reach 100%, then left the phone off for another hour before turning it on.
In a matter of minutes doing nothing more than checking my Twitter TL, the battery went from 100% to around 85%, and was still there went I tucked in for the night, leaving the phone in Airplane mode as I always do at night.
This morning, I turned Airplane mode off and the battery said it still had 82%, which means minimal drain during the night, with all radio off.
Just a few minutes ago, the phone went completely dead after the low battery warning, and the battery held less than 10% charge.
WiFi is off, cellular reception is very good where I live, and anyway, I don't see how LTE could kill 70% of the battery charge in less than half an hour, even if reception was spotty, which it's not.
I plugged the phone into the charger it came with, put it in Airplane mode again, and it went from 10% to 70% just now in less than 30 minutes.
I know for a fact that fast charge isn't supported on this phone, at least not with the OEM charger, plus it has micro-USB, so I doubt the charger can feed it that much juice in so little time.
The charger itself seems to work fine: It never gets hot while charging, not the Leagoo, nor my old iPhone 6, since I use it for both devices.
So, long story short, is there a way or tool to ***really*** know what state that battery is in? I've tried both DevCheck and CPU-Z, and both say that the battery is in good health, and still retains its nominal capacity of more or less 3,000 mAh, but I have my doubts about that.
I think the battery capacity is reduced somewhat, and I need to know by how much.
Any help and input would be much appreciated!
I must add that I flashed a stock ROM on this phone (yeah, again...) a few days ago, so maybe it's the ART cache being replenished that's causing my battery issues, but still, the problem is so inconsistant that I don't know anything anymore...
I had to flash the stock ROM again after trying (again...) to root the device (successful, but doesn't bring anything of value) and finding it barely responsive.
I'm gonna leave the phone as is, ROM-wise, but my battery is still a matter of concern, because it dies on me at the 60-65% mark more often than not, though two days ago I let it drop to 30% without the phone shutting down.
Like I said, it comes and goes. I really need to know if that battery still retains its nominal capacity or not. Any help in that regard would be most welcome...
Hey fourm, sorry for the long read but if anyone is technically savvy with batteries or voltages/electrical components please read! this might not be specific to a Fold but any device may suffer from what my device is suffering from.
I have recently had issues with my Galaxy Fold Z2 and it unexpectedly dropping to 0% charge, the first time this happened yesterday i was in an application and was switching from the larger display into the smaller one, upon closing the display the phone shut down and i wasn't able to get anylife out of the phone except a vibration when holding the power button, but nothing on the screen. I had about 35% battery at the time but all of a sudden it was at 0, after putting it on the charger it spring back into life. Today however i experienced an even worse problem... My battery was around 55% and i was connecting my phone to my cars bluetooth and importing contacts to the cars console, suddenly the battery went from 55% down to 9% instantly! i was shocked and took a screenshot of the battery graph showing its gradual decline from 100% to 55% but not to 9% to highlight the sudden drop, the battery status on the top of the notification bar was showing 9% all of a sudden but the graph wasnt just to actually see the drop! after that drop in battery it only took about a 30 seconds for that 9% of battery to jump down to 1% again in an instant fashion, following this only a few seconds later it shut down.I was thinking it could just be a dodgy battery for whatever reason but after trying to charge my phone after this sudden crash from 55%-9%-Flat i was unable to charge it up. The phone would signify that it was charging but not giving me a percentage, it would show the charging animation (the animation you get when phone is off and charging) but would only last for around 3-5 seconds before shutting off again and showing the charging icon again, and then shutting off again and rinse and repeat on a loop without charging but attempting too and resetting every few seconds! So for about an hour i couldnt get it to boot/charger properly and i almost gave up, but i decided to try a different charger, i was using the 25w supplied charger but i switched to a 15w older one and the phone ran the charge animation again however this time it identified the battery was charged at 55% rather that it not showing any charge level and resetting and trying again as it did before, this time it went right to 55% and from here the phone booted up and is working normally again!
Im really not sure whats wrong, im starting a process to send the phone back but i really wish to know whats wrong with my device! if anyone has any clue to this strange behaviour please let me know!
