the phone restart or turn off randomly and show different amount of charging
for example it was 17% battery then it turn of when i try to turn on again it shows 1% and turn off again
so i put it on charger for few seconds while it was off and it shows 100% battery then when i turn on again it shows only 5%
also while it was charging and reached 17% suddenly it shows 0% and turn off and charge back from 0% while it's off and remain on 1% for so long
what is the cause of that and any one know how to fix such problem?
I had the same behavior. It's bad battery. You need to replace the battery. My one was good until I got Android 10 and because of heating problem in our Android 10 I replaced the battery two times then went back to MM and all things good now. The heat broke the battery, especially during charging.
That was my experience.

i am having a quite unusual problem with the battery on my TP. it is hard to explain but i will try my best to do so. While i was casually surfing the web while on the charger i noticed that my battery started to drain ( this is the more ordinary problem that has been posted on many threads ) but this new situation is. The indicator lights and meters within the TP indicate that the battery is charging yet it still drains. I tried turning it completely off and removing the battery and then putting it back in and charge the unit for one hour. After one hour it charged to 20% which is reasonable enough for normal use, so i turn it back on and continue to use the device again the TP still indicates that the battery is charging after listening to about 7 songs i get a very low battery indicator warning (at the same time the battery indicates its charging) there is NO overheating and when the battery reaches 0% it does not die the screen just goes off and i can turn it back on and still recieve the low battery warning but what i cannot do is use data or even turn the phone radio back on. I am on the NFS 1.05 ROM, any suggestions?

Try to get a charger with an output of at least 1 A. It could be that your charger is not powerful enough to compensate for the drainage. The other thing is that WM' battery indicator flat out sucks... it is like Windows file system when it is desperately trying to tell you how much time you have left before your task is done (2 minutes jumping to 15 seconds jumping to 54 minutes jumping to 2 seconds jumping to 3 days, etc)..
Flash to another rom and see if the behavior still remains.... I doubt NFS messed up that badly with power settings, but it is always worth giving it a shot.
yea i doubt its the rom either as i was having overheating/drainage problems on stock but it wasnt anything like this
Hi there anyone have any ideas been using my Z2 since last Friday and yesterday for some reason the device will not charge to 100 % only goes up to 96%
I have tried a different charger and still get the same problem , Also downloaded Sony pc companion software and run the repair tool to see if it resolves the issue and still same problem
Try discharge battery to 1-2% (some advise even till auto-off device) and then fully charge with bundled charger.
Mine does the same thing, don't worry.
The reason this happens is that once your battery is at 100%, it stops charging automatically, and the device waits for it to get down to 99% before starting to charge again.
Is it possible that you just keep catching it at 99%?
Mine will charge about 1% every four minutes until it hits 99%. Then that last one percent takes a couple of hours. This is according to the power/percent list in gsam. It's done it consistently from day 2. Day 1 it failed to charge beyond 80% overnight.

thanks for your help I will try a full discharge and then try charging it and see how it goes
Finally battery is flat the phone turned off , charging it now with the sony charger which came with the z2 , will let you know what happens
I did a live chat with sony and they say the device is faulty and needs to be repaired
I have rang my network provider and they will send me a new z2
96% charge and wont charge no more!!
would really like to understand what is the solution to the problem.
This is really annoying . Please need all possible inputs.
Do you think its a product issue and needs to be replaced with a new piece.
Mine charges, but...
My Z2 will charge to 100%, but after it gets to 95% the screen turns on, and stays on.
If I push the power button on the phone to turn the screen off, the screen will turn off for between 0.5-1.5 seconds, and then turn itself back on.
I have gone through quite a few settings on my phone and can't find anything that might affect this other than perhaps "Night Mode" - which I have disabled.
Please help, my provider refuses to replace my phone even though I got it brand new from them and it's only 21 days old... I do love the phone, I just hate this issue - I can't leave it charging over night, or run the risk of having the phone over heat (it happened once, this is how I first found out about the problem, I had to leave the phone off with a fan on it for a good hour before it was cool to the touch again.)
@The Midnighter
I think you have a faulty unit, mine (2nd one) doesn't even overheat unless I have severe CPU/GPU intensive apps running. Never had a charging problem either... Get it replaced mate
I always charge the phone power off, when it is full charged I get the vibra notification and the phone is 100%.

I forgot to mention - you reminded me.
When I leave my phone off and plugged in, it will charge to 100% - however I have to do a HARD RESET every time I go to turn my phone back on, after turning it off. (Holding power and volume up) or it sticks on the "SONY" screen and will not advance.
Since xperia S there is a feature which helps battery keeping good condition
Its charge to 100% and turns charging off till 95%
Its all becouse integrated battery
This is not a bug or problem

It is indeed a problem, because the screen is staying on and causing my phone to over heat - it once over heated so badly because of this I had to leave the phone off for a very long time.
The phone doesnt charge at 100% and the magnetic charger not work

I have the exact problem. The phone work ok for a few days and then stop charging at 92% and the screen stay on. I plug the charger in the night and in the morning was only at 92% and hot, very hot.
A few days ago I bought a dock charger and an usb cable to plug in the magnetic lateral charging port. And with both chargers the phone shows the charge icon for a second and desapear for another second and repeat the loop.
I try everything in the software level. Restore the firmware using pccompanion and also flash the lollipop firmaware but the problem persist. Just not tried delete the battery stats because my phone is not rooted yet.

Did u manage to fix the problem? Or did anyone here manage to fix the battery charging issue? Mine charges to 78%, then sometime 85% then hard-reset - 91%. Cant charge anything above that! : <
There's no real fix, you can only hope a rollback to KitKat might help. See this lengthy forum post on the sony forums:
https://talk.sonymobile.com/t5/Xperia-Z2/Lollipop-charging-bug/td-p/965384
Spanning from april until right now...
Mine only gets to 70-80% on an overnight charge.
Mine charges and discharges constantly, I try change the cable, the AC adapter, the usb on my computer, the micro usb port to magnetic... Always is the same.. and another times charges too good.
Some times charge to 99% and discharge to 98%.. so I disconnect and connect again and charges to 100%
Maybe it's a Lollipop .232 problem in some devices?
Hi! Same problem here, sometimes my phone doesn't charge to 100% and I have to unplug the charger and plug it in again to get 100%. I think it's pretty common, but if your phone only charges till a low percentages and just doesn't charge further, it might be so that the phone's afflicted with the Lollipop charging bug. We can only wait for Marshmallow then
This is not happening for the first time...
Ever since I rooted my device and flashed Android Revolutionary Rom on it, I noticed some weird behavior with my device/battery.
Last night I drained my battery to 6% and I turned it off. This morning I charged my phone with the phone stayed off and when the battery indicator screen lighted up it was showing that 50% juice remains. Since this is not happening for the first time, this time I would like to test on it to see whether there's really this much juice remains. So I turned my phone on and as expected, the battery indicator shows 50++% left. So I play around with it and I noticed the screen flashing terribly after some time. Not long after that the phone hang there and I had to do a hard reset by pulling out the battery. Before that, I can see that the battery is drained to around 20%. I was unable to power it on after pulling out the battery and when I connected my device to the charger, nothing happens (no display, no LED). So I left it there charging and after some time, finally the LED is lighting up (So, I assume that I drained the battery COMPLETELY just now). I can switch on the device afterwards and it shows 6% battery remains. I wonder why is this happening as this only happens when I charge my device with it turning off. Something wrong with the battery? Device? Or I have to do battery calibration?

Let it charge to 100% first before using. Then check how is the battery usage.
There might be an issue with the battery also. If it is swollen then it's time to get a new one.
Try using another battery and see. If it works fine on other battery then your battery needs to change,
The problem could also be in the ROM. Something could have gone wrong during installation even though it may look fine. If this is the case then reflash the ROM with a full wipe. If the problem still remains, return to stock rom and see.
I had the exact same problems, the screen flashes and stutters, network signal is lost and the phone turns off, it is due to uncalibrated battery.
There's a simple fix, download battery calibration from play stor (green android icon with percentage), charge your phone to 100% without using it, then click battery calibr. inside that app, then doscharge it till 0% (do your normal usage as ussual) and then charge it back to 100%
For healthy battery life don't let it drain lower than 10% it's the li-ion physics and always charge it fully, don't charge from 0 to 30-50-60% because the ions in the battery will not have a good flow.
Everything has it's lifespan but if it's configured and used properly it can have a long lifespan
Also to mention, if my recommendation doesn't work, your battery could be swolen due to inproper charging / heavy oc-ing or your charger is messed up.
Also to say, that flickering occured to me when i flashed a new rom and when i do lot of reboots, then the batterystats freak out, the voltages also and also your phone.
Charhe and use it properly, try to stay with a rom at least a couple of days to see how it'll go.

The battery usage is normal, and its not swollen. I guess I will try to calibrate the battery or reflash the ROM again.

Yea, I will try to calibrate my battery to see if it helps
Ever since I got this device I've had issues with it being unable to correctly detect the battery level. Very often the phone discharges completely and shuts down, and upon a restart it shows 20% battery left.
I've tried calibrating the battery, but I'm either doing it wrong or it's not working... What else can be done to fix this discrepancy?

From my experience, if you use ROM based on Android 6.0 this can happen and in this case you must recalibrate the battery by draining it completely by few restarts and then charging it to 100% and leaving it on charger for 1h more. If you use 5.x Android this behavior is a sign of a battery loosing it's capacity. In which case you need new battery.

Try to use slow charging couple times, I mean 500ma charger or charge via pc slot.
Hello,
The battery on my Z2, after almost 4 years, wasn't able to hold on, so I have to replace it. I bought a new one and successfully replaced it. Now the battery life is great again, but unfortunately I run into a annoying problem. I fully charge the phone, and after I unplug, no matter if I use it or not, in matter of 2-3 hours the battery goes down to 1% and it stays at 1% the whole day with normal usage. So battery life is how it should be, but the percentage that it shows is not correct. I tried "calibrating" the battery (fully discharging and charging) but that didn't work so I tried repairing with Sony PC companion. That says that is reinstalling the system, so now the phone is like new, like factory reset, but still the problem is here. Now it goes maybe from 100% to 70% in 3 hours and then stays at 70% for 4-5 hours and again starts rapidly decreasing till it reaches 1% and stays at 1% for a while till eventually it shuts down. Any suggestions how I might solve this problem? Thanks in advance!
