Sony Xperia Z1 Poor and Short Battery Life and Sudden Battery Charge Drops

Greetings everyone,

 

I am the owner of a four month old Sony Xperia Z1. So far, it has lived up to its name, apart from the reliability of its battery.

When I purchased it back in August, the battery life was pretty short, but maintained its charge as demonstrated on GSMArena. I would only charge it using the Sony EP-800 850 mAh charger which came with my former Xperia Play back in 2012. I never used the EP-880 charger which shipped with the Z1 under the impression that slow charging will allow slow deterioration of the battery. Despite the low peak output, the battery gained a single percentage worth of charge every 4-6 minutes, and showed no problems.

About a fortnight after its purchase, I was booked on a trans-Atlantic flight over 10 hours where I charged the device through the USB port integrated within the in-flight entertainment system. That was the only time I noticed an anomaly with the device's charging pattern where it would require 19 minutes for a single percentage. In case anyone wondering the model of the aircraft, it was the Boeing 787-8 Dreamliner.

Since then, the charging pattern has been regular, until October, where the battery would require 10 minutes for a single charge. I started noticing this after my original Sony USB cable started malfunctioning, and used a $4 one instead.

2 months later in December, however, the battery is charging quicker, but I noticed something worrying only yesterday.

Last night, I topped the battery to 100%, switched WiFi, data, NFC, and auto sync off, and had Stamina enabled. The next morning, I noticed the battery had lost charge from 82 to 60%. I have attached a graph of this unusual loss of charge below: (Second one)

 

After a further analysis, it seems the battery lost this much juice right after I put the device to sleep, and turned WiFi off. Today, I left my house with the battery full, and after a few minutes, lost 10% charge. The first graph attached illustrates this.

 

My initial assumption would be a Google based application in the background running a conditional loop, trying to synchronise (my YouTube notifications haven't been disabled) while the WiFi and mobile data are switched off. However, I would appreciate if a Sony specialist could offer some insight to this dillema. 

 

Many thanks.

SONY XPERIA Z1 BULGING/SWELLING BATTERY - URGENT INTERVENTION REQUIRED!

Hello All,

 

I purchased a brand new Sony Xperia Z1 C6903 from an authorised Sony dealer in Lahore, Pakistan on the 8th of August.

The device is under warranty.

 

Two months ago, I started noticing issues with the battery where it would not charge quickly (bear in mind I was using a Sony EP-800 charger rated at 850mAh), and would lose about 8-9 percent of its charge overnight (though I believe this may be a software bug).

 

Since I would stuff my device in the front pocket of my jeans, I wanted to find out if my device had fallen victim to the infamous 'bend-gate' phenomenon which struck iPhone 6 users last year (yet another reason why we prefer Android!) I placed a ruler on the back of my device, and noticed a very, very slight bulging on the centre of the back where the "SONY" logo is printed. The ruler would be resting about 0.1 millimeter away from the nether regions of the device where the camera, and speaker/microphone are mounted. The device would also lie on a flat surface with less than a millimeter to spare on each side.

 

I found this revalation quite alarming since the device was purchased only 4 months ago, and I never let the CPU, or battery temperature exceed 40 Celsius. I am uncertain whether this could legitimately be a swelling battery, a manufacturing defect occuring from a lack of accuracy for determining the flattness of the glass back, or be a case of severe paranoia where I would worry myself over a slight imperfection.

 

The device was purchased for about $300 CAD off contract. Since I am Canada, I am unable to redeem my Sony warranty which is only applicable within Pakistan. At the moment, my service provider is Rogers.

 

Since I am unaware of the cause, I would be grateful if Xperia Z1 users could measure the 'flatness' of their device, and reply their findings to this thread.

 

Honestly, I am very unimpressed with the quality control of Sony devices as opposed to the Xperia models marketed by the Swedish Sony Ericsson. I still have my Sony Ericsson Xperia Play which I purchased back in 2012, and have had no issues whatsoever with the battery bulging. Finding this issue after four months of careful usage is outrageous, and a severe safety hazard for a four month old device.

 

Nevertheless, this is a great device for the money, and am grateful of the fact Sony is using Triluminos panels for their new flagships. However, the camera quality is atrocious, and Digital SteadyShot will introduce tremendous amounts of motion blur.

 

To all forum members:

Please rest your Sony Xperia Z series device against a flat surface and report whether or not the device sits flushed. If possible, please do upload images.

 

Thanks!

 

I have provided pictures of the handset for better interpretation, though please be aware they might not provide a proper insight to the purported issue.

Sony Xperia Z1 Sudden Battery Drain and Swollen Battery

Hello all,

 

I will get into exact details:

*I have a 4 month old Sony Xperia Z1 C6903

*I am still rocking Android 4.4.4 and after reading the problems users have encountered after upgrading to Lollipop, I refuse to update.

*I have been using the EP-800 charger that came with my former Xperia Play for the past two months. However, when I first bought the device, I chargd it through a 2.1 ampere USB adapter. It was unbranded.

*For the past two months, I have been observing abnormal battery drops from 80%-60%, and 50%-0%.

*If I use the camera and fire the flash, the battery will drain from 50% to 0% in a matter of seconds.

*There is a lump on the back of the device, where the SONY logo is printed. I believe this is caused by a swollen battery.

 

Is this a software/firmware defect where the battery analyser has gone out of calibration, or is this a case of my battery growing dendrites? Since the device is stil under warranty, can I get it replaced on the spot? I will be flying out in less than a week and am unable to wait for the device to be repaired.

 

Here is a screenshot of the battery consumption graph:

notice that the drop from 50% to approximately 30% was after I used the camera for recording a full HD clip with the flash turned on for 32 seconds.

Re: Sony Xperia Z1 Sudden Battery Drain and Swollen Battery

You should stop using the device as you could damage it further and worse, you could get hurt, perhaps the battery got in contact with water. Contact your local Xperia support to get the device inspected

Re: Sony Xperia Z1 Sudden Battery Drain and Swollen Battery

image.pngSorry about the multiple posts. Seems like there is a bug in the forums!

But anyway, I am unable to use the device after losing more than 50 precent of charge.

IF you have repaired the phone with PCC and you still experience this issue, then it could be a hardware issue, and you will have to contact your Local support

Re: Sony Xperia Z1 Poor and Short Battery Life and Sudden Battery Charge Drops

What you are experiancing is a very common battery issue fot Xperia Z1 users. Almost all the Z1 users havebeen affected by the sudden battery drain bug execpt few lucky ones where the battery drops in leaps like 9% to 10% while in idle. When it reaches 50%, the phone will shutdown.

The only viable solutions for the issue is to replace the battery. Return the phone to Sony service center if it's still under warranty.

My Z1 is just 7 months old and I started experiancing this since last month. I ordered a new battery from EBay and waiting for the shipment. Also, my phone's battery is swelling up same as yours.

Re: Sony Xperia Z1 Poor and Short Battery Life and Sudden Battery Charge Drops

Well, I am quite flabbergasted as this is the only solution. Since I will be flying out in 4 days, do you think Sony will just replace my device straight away, or will their technicians actually disassemble the device, and replace the battery - something that could take up to a week?
I purchased an Xperia Z3 on Sunday, just in case the Z1 threw in the towel (which in this case, it did). Do you reckon the Z3 suffers from identical issues?

Re: Sony Xperia Z1 Poor and Short Battery Life and Sudden Battery Charge Drops

As far as I know Xperia Z1 and Z1 compact phones suffer from this problem. Some people claim that this happened after the Lollipop update. But, the actual reason is the poor quality batteries used by Sony for these devices. This would happen even if you are on Kitkat.

Sony service center might take around 2 weeks to replace the battery depending on your country.
