The phone was freshly charged overnight. I was using the internet while listening to music through (3rd party) headset and since the 3G signal in the building was kinda ****ty I switched the phone to EDGE (GSM only). Then I quit the Settings menu and opened Firefox, tried to load a web page and at this point the phone froze. I'm not sure if I restarted it or it restarted on itself but after the boot the battery was showing about 40% less. So I turned the phone off, pulled the battery, rebooted, same reading.
I used the phone for a while after that and now it's showing critically low battery and I'm wondering what should I do now?
Is it really so low on battery or the reading is wrong?
Can 40% battery disappear just like that and what could cause it?
Should I charge the battery or let it discharge until it turns off by itself?
Battery screenshot attached.
Perhaps a battery calibration issue caused due to the crash, my advice would be to drain the battery all the way down to zero and let the phone turn off, remove and reinsert battery and proceed to charge till full and then turn the phone on again. Hopefully issue should be a one-off and now resolved.

happend to me before on my htc desire hd..battery pulled and battery stats dropped down the gutter..just let the battery die and charge fully or even just charge it up to 100% from where u at now..doesnt matter it will fix itself...
My phone was doing the same thing, it was rebooting or shutting down two or three times a day, usually a few minutes after taking off of charge.
I have sent it back for a replacement.
Do not drain the battery to zero. There is not reason to go belox 10% charge, as you could damage the battery if going to 0. These are new batteries much smarter then old ones.
You don't need to drain to zero but it won't do any harm if you do. Probably a wee softwre glitch. Wouldn't get too worried about it.
a good option is battery doctor - its a free aplication from the market...
let your battery go down to 20% and then open the app in charging mode...let it charge(dont close the app during the charging process, just keep it open)...woallla.. u have made a full cycle charge - easy as that...
This morning I used my sister's Samsung Champ's charger to charge my Galaxy 5. I didn't keep it in for long (20 - 30 min) but when I removed it, the battery started showing low charge warnings; I tried charging with my laptop using the cable that came with the phone and it showed 70% charged immidately, but when I removed it, it showed <14% warning again.
I tried to drain the battery completely and then recharge it, but the battery is still draining fast. Please help, the phone is only 2 months old...
Did you do a full charge?
I don't see why using other chargers effect your phone, I always use blackberry chargers and have no problem, try charging to 100%, draining to 0% a few times, see if it helps

It might have nothing to do with using the wrong charger, you might just have the signal glitch where your phone is constantly searching for signal when it already has it, my phone started to do it recently, to check if this is the issue go to Settings, Phone Info, Battery Useage, Signal, then if it says something like Time without signal 50% then that is the issue.
Try this;
Unplug your phone
Turn Airplane Mode on for about 10 seconds
Turn Airplane Mode off
Restart phone.
That fixed my battery life- it was going for 80% battery to 10% in under 5 minutes.
For some time it happens sometimes that what I'm reading or something else that I hear a beep and the battery suddenly turns red and then automatically turned off.
He is not on, I hang it on the charger will start it after some time, but the battery is not empty. Just gave this 55% when I hung it on the charger.
Any ideas what this is?
Run the phone until it shutdown of its own accord, then fully charge, till it says charged without unplugging at all.
This should straighten things out.

Are you using any app/widget for showing anything related to battery?
Similar thing happens to me but only below 10% when I used some apps/widgets, so strange that it happens to you at ~55%.
I use the battery ap of beautiful widgets.
I read the phone battery as those in state until it is full. Can I use the charger therefore out when it is full and has not launched yet?
do a battery calibration
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
Hi All,
Please help me with my battery problem.
I was playing some game, the phone had around 30% battery. Suddenly it went off. Then I tried turning it on. It showed 0% charging. I left it for sometime, it still showed 0% charging, and since then its showing the same. It shows 0% charging when I use an external charger to charge it, as soon as I unplug it, it goes off.
My findings :
I trired a few on and off tricks, I cant calibrate coz I can't charge phone to 100%. Then I left the phone on charging for a few hours, it did charge, and somehow the battery showed 100% charged, but when I unplugged the charger, the phone shutdown quickly.
The battery is in good condition, I have used a few apps to check that. The battery is still charged, but the phone doesnt know about it, and reads it differently, phone always finds battery to be 0%. The battery stats show "0 seconds on battery",so I guess the phone isn't using battery at all. I tried hard resetting as well. I believe its a software problem not a hardware problem.
Please help me, I cant get extra battery as of now as I am not at my place, I will be out for 2 more weeks atleast. Neither can I submit my phone for repairing until I am back at my place. Why is the phone not using the battery that is still there? Can anyone help please?
Replace battery, and if that doesn't fix the problem replace USB board/port.
Replace battery with a reputable battery. It will fix the issue.
