[Xperia Z5 Q&A, Help & Troubleshooting] zacharias.maladroit:
The 20% can be explained as a "default" capacity during initialization of the fuel gauge of the battery.

It's standard behavior and can be seen on all devices, when the phone is really off then connecting it for charging - it initially shows 20% then after a short while shows the correct (current) value it is at.

This was introduced with ~ 185 Marshmallow release afaik (https://github.com/zachariasmaladro...7a30640#diff-ba1944522cdd0a230c7769e47eefcd48)

https://github.com/zachariasmaladro...40#diff-ba1944522cdd0a230c7769e47eefcd48R1287

and is in effect with the new qpnp_fg_extension addition of the battery driver - which is needed for the MHL driver (supposedly notifies it, perhaps showing battery state while connected, etc.)

So when using a ROM that is before 32.1.A.1.185 the problem either shouldn't be there or the battery (assumedly) should be stuck at 50% [Snapdragon 810 device "default" initialization value]

can anyone confirm this ?

Also: are ALL of you guys using the battery optimization feature ?

Does turning it OFF help ?

Anyone of you with this problem has waived their guarantee (unlocking bootloader) ?

[e.g. if it's a hardware issue there's still warranty in Germany but you have to proof it after 6 months of owning it]

Do you guys e.g. run a 32.4.A.0.160 based ROM ?

If you're willing to experiment you could try out my custom kernel and see if the battery state changes, it has modifications to the calculation and display of the battery state (it also has a fix for overflow / corruption of battery state),

I doubt that it'll make a difference though but it's worth a try.

Reading through https://www.androidpit.com/how-to-calibrate-the-battery-on-your-android-device

I got the idea that perhaps some data on the battery, on storage, etc. might be corrupted so fully doing a factory reset, letting the battery fully discharge (don't do this often - it's unhealthy !), etc.

might reset it ...

Have to think about this and see if there's a way to force-reset the state of the battery ...

edit:

Do an "emergency shutdown" - but for a longer duration (since you want to avoid having to open the device and totally void warranty)

Power Button + (shortly after) Volume UP

keep both buttons pressed for ~ 1 minute at least

that should clear any PMIC related remaining data

then see how it behaves afterwards ...

Good luck !

[Xperia Z5 Q&A, Help & Troubleshooting] Ashdog73:
Hey everyone, I just thought I'd post on this thread as I had this problem and managed to "fix" it without taking the phone apart or pressing any internal buttons. I had the 20% charge issue, read this thread and decided to live with it rather than invalidate my warranty or risk damaging the phone further by taking it to pieces. I lived with it for about a month and then one day I was out overnight and took my portable battery charger with me. I forgot to turn my phone off when I fell asleep and when I woke up in the morning it was absolutely flat. So I plugged in my battery charger and left it on the car seat to charge up while I drove home. When I got out of the car I noticed that the battery indicator was reading 84%!! I was surprised but sceptical so I let the unit run down and yes it went below 20%! And it's been fine ever since!

I'm not an expert but I'm guessing some interrogation went on between the phone and the battery charger and it must have refreshed the charge controller in the phone.

So before you take your phone apart, try plugging it into a battery charger! I'm not guaranteeing success but it worked for me! My charger is a coolreall k6 BTW, in case that helps!

Cheers,

Ash

I too had same problem.

Battery stuck at 20%.

factory reset, firmware reset.

Some are saying that battery to be replaced, DON'T KNOW WHAT TO DO ?
[Xperia Z5 Q&A, Help & Troubleshooting] l_abaurre:
Sounds like a dead battery to me. I had to have it replaced. But watch out where you do it. The company I used ****ed up the polarizer and the screen is now all "wrinkled". Since the phone wouldn't turn on (to prove it wasn't like that before) they didn't claim responsibility and I was screwed.
[Xperia Z5 Q&A, Help & Troubleshooting] coventgardenmartin:
This worked for me. Had the 20% problem, then took out the sim card, didn't have an SD card, then let it sit while charging and an hour later put the sim back in and it worked.
[Xperia Z5 Q&A, Help & Troubleshooting] exploit777:
Got same issue - stuck %20

Tried all type or reset, reflash, chargers, cables, charging sequiencis etc. - no go.

Opened phone and disconnect the battery for 20 seconds approximately (just to check if there is any visible damage or corrosion or oxidation oh battery connector) and plugged battery back - voila got %75 when switched on and still keep going up.
[Xperia Z5 Q&A, Help & Troubleshooting] PioneerSeeker:
The battery of you all people got heat up and you all people should do one thing to prevent the battery from getting heat up in the future.

And the advice is that you people should use your Sony Z5 in Siberia (Russia) in -70 degrees temperature.

What this action will do that the battery will never get heat up.
[Xperia Z5 Q&A, Help & Troubleshooting] mtrantalainen:
Wow! I had the same issue with OEM locked Xperia XZ1 Compact (battery percentage always displaying 20% no matter what I do).

Doing the above (while the system is running, press and hold power button, 1 second later press and hold volume UP button, keep holding both buttons for around 60 seconds and press power button to restart the device) fixed the problem. The battery percentage now shows sensible values and increases when I charge the phone.

So it's possible to fix the issue without rooting the phone or taking it apart. (Those actions are needed for other stuff and I may still need to do both in the future.)

Sorry to bump this thread....

My Sony Xperia 1 Dual Sim J9110 also exhibits this 20% battery problem..

I have tried everything from charging over night, reinstaling firmware, factory reset, vol and power button pressed etc but still remains at 20%

The battery is charging but takes around 5-7hours for a full charge..

I am getting around 7-8 hours screen on time

The phone is fully functional but never know when it will die and turn off as its always on 20% battery percentage

Any one can help please do

Cheers

Hi there, I Am a big Fun of sony z5 compacts.... and i found this problem also.... there are many many themes about this "stuck at 20%" :) Problem is nobody tells what was before.... so i wanted new battery--- problem was after that... installed okey... 4 advanced users... but yes it suddenly comes to 20% and when i charged it it stays at this volume... but!!! if you quite your phone and let it get 100% non operating.... but charging---- try to start the phone.... still connected to the charger..... then, it will show 100% stucked at :) and not 20% :)

unlock cable,,,,, no problem real is 4 now.... 100% but you are stucked at faking 100% for ever and not at 20% :) 20% is the same :) as 100% :)

Phone is full charged but shows stuck 100% or stuck 20% :) idiot

Then if you make restart..... you have got again 20%, :) if you try hard reset volume+ and main click.... same, yellow secret click and main click.... no sololution you are at 20% :)

Try to make factory reset.... noooo nothing happens :)

So what to do? At Sony Z5 compact E5823 make this:

change battery and check if it works.... then quit the phone, shut down no matter what it shows. shut it down. and get it to AC or better to mobile AC..... when it shows 100% .... there must be 100% shown.... not like a full but ||||100%||||| okey then make total data ReSET ...... when indicator of !!!!shutdown mobile!!! shows 100%, by pressing volume UP+ and main connector.... do it 3 times, I have made that....... dont know if once is enough... but triple action is okey :) mobile must be shut OFF!!!! :) and data cable must be in still... and check if there is still 100% upon the battery image.... after 3 flashbacks.. there is okey....... disconnect""""" cable and start your phone....... there will be 100% and no problem at all.... :)

100% YES YES YES but not stucked YES YES YES :) it will get down.... up as you want... like before... this is how to formate batteries at sony. Daimn good daimn bad :) surprise.... not so easy.... trick...... but i foud that by myself and this forum too... this a real sh!t happens :) when you want 2 upgrade battery.... so f u cking problems....

Try this.... and let me know..... if it worx crazy worx....

This should funktion at any Sony smartphone.... but.... who knows...

You can visit my forum 4 some snaps... and maybe translated info :) noone can translate me :) but one picture means 1000 words....

Battery tested, and it is fantastic.... charged after when running at 18% it charged to 100% and woks like new....

6 hours on wifi only no work to do.... still 100% when i made something... 99 98 97 and so on :)

Z5 compact like a new....

with old battery same situation, nothing to do.... but capacity was after 6 hours 10% or 20% down--- bad battery.

So I am happy I have 3 absolutely new Z5 compacts..... And I dont know which one is better :) :)

They are all re-transformed, and fully renewed.... :) As new. All were from official distribution.... so they have LTE 800 :) NFC and other things.... non proximity sensor problems- original displays :) Nice to build them.... Hobby.

New Battery is one big Joke :) only one needed this stuff.... okey...I know, how to make it. :) not to be stucked :) this was really CRAZY!!! psycho Test.... On me.... I have passed 1* :)

So 20% stuck or 100% stuck is not hardware problem at ALL.... only software.... thats it.... you have to show to software error who is the boss.... user is the boss :)

+how to find official motherboards of Z5 compacts? okey.... 35428207---- that means this IMEI is official EU distribution and it is not refubrished pakistan sh!t.... with japanese board without many functions.... and bad quality. I had One..... so I can tell.... I´am right.... :)

There is full Ebay and others with these sh!ts..... that´s funny and funky :)

Imei is: moment :) 35980606-----these are japanese Imeis.... and not Europe official.... not LTE BC20 800MHz and so on..... all these have already bootloader unlocked.... or are unlockable.... both is bad.... good is at originals.... bootloader can be ulocked....yes---- but originals are factory locked- advanced users menu OEM . . When bootloader is unlocked, you cannot flash them.... you will destroy motherboard, IMEI number, DRM keys and all...

At Z5 compacts I am really mega advanced user :)

Also if you make Z5 compact hacked to Lineage OS..... you will loose camera and flash for EVER..... so dont do it :) let it be original.... please.... poor z5 compacts.... no dont do that! You cannot return what you have done.... never!

Hi Everyone,

Ive upgraded to WM6 and all my GPRS settings have gone so I cant get on the internet or send/recieve picture messages.

I have the settings from Virgin but dont know where they go in the phone.

I know you have to have two settings, one for internet and one for gprs.

Does anyone know whether the internet settings go into "My ISP" or "My Work Network". There doesnt seem to be enough settings on the Virgin website to fill in on the phone.

Is anyone else running windows mobile on Virgin and have the settings working?

Thanks

[Android Q&A, Help & Troubleshooting] adam.nox:
I have a problem with both the Moto E 2015 verizon, and the tracfone huawei glory. In the moto, there's no hope because it can't be rooted yet.

However, maybe I can do something about the Glory. Here is what it does: The low end of bass is cut off or tapered off sharply. If I turn on bass boost through DSP manager, it actually gets worse. If I then turn bass boost to 0, some switch gets flipped and all the bass comes through like it should. Unfortunately any reboot reverts this, possibly other situations. It's no good for my purposes and would like a permanent solution.

For anyone wondering, the Moto problem is a little different, where 90% of equalizers have no effect on it, and it too has bass cut off. One EQ I found did work, but had to turn it off and on each time.

BTW, this is for streaming music apps, not music players that may have their own built in EQs.

As the title suggests, I am having trouble with a bootloop after successfully rooting a BOK3 stock GS5 5.0, installing SafeStrap and successfully flashing steps 2, 4 and 8 on this guide.

I can exit the bootloop by pulling the battery, booting into download mode, downgrading to the ni2 kernel using Odin and finally making it back to SafeStrap. From here however, I'd like some input on how to proceed.

I think I'd like to try to revert all changes through whatever means, all data has been backed up so I'm not concerned about that.

Thanks in advance

Not necessary in this case. Will actually result in the same issue. The Nexus Player on CM based ROMs has this bug. It'll get to "Optimizing Apps...", and sit there eternally. No known fix, and the guys at CM said that TV devices aren't a priority, so the bug won't be fixed most likely.

All you need to do to work around it is to get to that screen, unplug, and replug. That simple.
