It seems like Sony had defective batteries in some batches. In eastern Europe owners forum we also had few guys whose battery would expand but others had no problems even with latest software.

I've tried Lolipop 5.1.

Taken phone to sauna where is 100 degreen for extended time where phone becomes too hot i can't touch it.

It has seen all sorts of liquids from beer to piss. It even got salt water but i replaced the rubber flaps afterwards.

Numerous times i let the phone just die cause i didn't feel like charging.

Using all sorts of cheap ebay chargers.

With all this abuse there are no battery related issues. Still giving me 4.5h sot and ~3-5 days standby after 1½ years of use.

Now it would be interesting to point out the batch number when having battery issue.

I've got 14W15 which doesn't seem to have battery issues.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] einfachgaer:
Having batch 14W11 and no battery issues for now, I'm using the phone since mid April 2014.

Like 4 hours SoT without any battery saving modes like stamina.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] New Folder:
I dug in Sony official forums and it seems that sometimes battery controller gets malfunctioned when upgrading to Lolipop.

Apparently 60 USD or 50 GBD fix is all that is needed and the only solution to fix sudden drops if your out of warrant. Althou warranty has to fix it for you when you still have it.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
I'm guessing that can be fixed by replacing the battery itself, which is how most of us have fixed it at this point.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] rumpocky:
I had a similar problem and it turned into the worst experience I have ever had with Sony. No one should have to go through this but I guess it comes with the technological and business world. I ended up sending my phone in for repair to Sony's repair center and they evaluated and tested it. They contacted me and told me that they would proceed with repairing it once I gave them approval and paid the repaired cost. I gave them the approval and paid the money. Afterwards I didn't anything from them for over 21 business days so I contacted them and they told me a part was back ordered and that they were waiting on it. I contacted them a week later and was told that the part was not available and that they could not repair my phone so they will be sending my phone back and refunding me. I received my phone back unrepaired and I'm still waiting on the chance to get my money back. I was still holding on to my love of Sony products when I bought the phone in 2014, feeling that it would be just as durable as the other products I bought in the past, some of which I still use but this experience has ended that, making this the last Sony product I buy.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
I'm really sorry to hear that. Like you, this tainted my experience with sony as well. I've moved onto an LG phone since this happened (battery started acting up again after being replaced once, not going through that twice).
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Revontheus:
After experiencing this weird battery issue I had mine replaced by Sony free of charge since my Phone was still under warranty, Sony warranty does it for free ( In my country ) if you provide sufficient proof that its not "user caused"

I suggest you send the phone to Sony as battery problems are usually hardware related and not software problems

Good luck! :)
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
For a lot of us this happened more than a year out of warranty.

That's weird, which implies my battery failed earlier hahaha. But most of you have it solved right? I suggest Greenify that app works wonders for both my phones
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
We all fixed it by replacing the battery. It wasn't something software (like greenify) could have fixed. Thanks for the suggestions tho and glad your phone is fixed :)

Read in a Sony forum that sudden abnormal drop, (as opposed to fast drain causes by battery hogging apps/ROMs), can be triggered by leaving the phone plugged in after full charge. I didn't know about that, but I know that I do that quite a bit, so going to try taking that on and see if it helps. I've been getting 20-30 % drops after reboots, usually once a day or so. (AOSP MM)

Bit the bullet and changed my battery and backpiece since I also had problems with my battery suddenly dying.

Over 1½ day on with about 5½h SOT. Stock 5.1.1 with debloat script. Back on track again. :)
[Xperia Z1 Compact Q&A, Help & Troubleshooting] camaro322hp:
Add me to the list. This started happening to me shortly after upgrading from 5.0.2 to 5.1.1. Phone was basically unusable since it would die randomly when battery was less than 60% or so.

Replaced the battery with a $12 "genuine" battery from Ebay, and all is good now.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] MrBratka:
Had the same problems sine past two weeks, first time I experienced this issue, when I was driving out of town using google maps it just went out at 40%, then the problem repeated, I haven't changed anything in my system for past 2 months, and the problem just came out of nowhere.

My phone discharged faster than in 12 hours with moderate usage, powered off at exactly 40% everytime. Tried everything to avoid changing the battery, cause I am not planning to invest any more money in three years old phone model, which will not get any updates from Sony, but I still think that Z1 is far the best mobile device I had in my hands, except the battery problem of course.

I tried re-flash the same version I currently was running, 14.6.A.1.236, but the phone discharged from 70% in less than 5 hours, only by using the calculator app :P

Read every single reply in this thread. And decided to try some methods that people tried here.

And I had my phone running on ~30%, and I tried to roll back the firmware.

Firstly, I downgraded my firmware to version 14.5.A.0.242 (the one I bought the phone with)(also noticed that my battery increased by 40% after the flashing process, which was kinda strange as the firmware flash process took like 5 minutes), didn't signed in to any of google services and used the phone mainly for calls and messages, then used it for a few hours and the problem seemed like it was gone. Then my phone did a full discharge from ~50% to 0% like it was supposed.

I also changed my charger from EP880 PIC (which was given with Z1, which outputted 1500mA) to EP800 PIC (I had it laying on the shelf since I own a XPERIA Mini Pro, which output is 850mA) That resulted in a slower, but in my opinion much safer and more reliable charge. And charged my phone to full charge (tried not to overcharge and unplugged the charger the same moment my phone reached 100%).

Later that day I updated my phone through the phone update service, then there was another update, and another, then it seemed like the last one wasn't installing successfully for no reason, but that's not the thing... Now my phone is running on version 14.6.A.1.236 (the latest one). It's been 12 hours since last full charge and the device is still running at 60%.

In short, I roll backed my firmware, and changed my charger, since past 12 hours phone only discharged by 40%, and seems to work like it was few months ago.

UPDATE: After two days of testing and using the phone battery holds for longer period 1.5 day. And the battery drops from 50% to 30% but no more sudden shutdowns as before. I am still thinking of battery replacement soon as it should increase battery life longer.

Where to find this?

Hi there, sorry for the naiive question. I just started looking through this forum because I'm having the same problem as many people here, and I saw this post. Where can I find the service menu on my z1 compact? I've looked through all the settings and can't seem to find it..

Cheers!

Hi team, Over the past month or two I've been having the same problem as many of you with my phone's battery. It will be discharging at a normal rate, then suddenly drop.

Original symptoms:

Normal discharge until ~30%, then very rapid discharge down to ~5% from there.

Steps taken:

Linked to phone companion app on my computer, backed up my phone, then did a 'phone repair' through the app. After which time I restored my back up.

I took this step because I had already found it as a suggestion of a likely fix for my battery problems online.

Current symptoms:

Well my phone no longer routinely dies once it hits ~30%, instead it has more frequent, less dramatic drops in the battery (but still annoying!!). Yesterday evening I performed a full charge, taking off teh carger at 100% battery at ~11pm. Checked emails/facebook before using Battery Dr. app to stop/hibernate any background apps overnight - and subsequently left the phone on my bedside table for the night.

This morning, I wake up to 77% battery. Not a catastrophic drop, but still very unusual, I used to get 2 days out of my phone, now I'm lucky to get 1.

Im a new user so I cannot post images of my battery usage graph taken from my phone, but basically it starts at full charge, theres a tiny drop as I used the phone before I slept, then there is a 'cliff' as it drops rapidly down to ~77% just after 1am, before levelling to almost horizontal, a very nice plateau until the morning. The app data under the graph shows usage since last full charge as follows:

Cell standby - 4%

Screen - 4%

Phone idle - 3%

Android system - 3%

Does anyone have any further, wise suggestions as to what I could do? I have a z1 compact, non-rooted. Im not a techno-muppet, but I'm also not a pro, so please bear with me. I appreciate it in advance!

[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
I used a new back because it came with new sticky tape and the original stuff was very hard to maneuver to restick.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] alex_hk90:
It depends on how cleanly you take it off. You will probably need some new adhesive/thin double-sided tape to use the same back cover again, but generally it should be possible.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] FadedShadow:
I have a similar problem with my z1 compact regarding battery drop, however, instead of the battery power going down super quickly, it will just cut out when I can see the battery is (for example) at 80%. I have had this problem regardless of the current power of the phone, and as I say, it will cut out completely as though the battery has died. The only way I can turn the phone back on again is when it's plugged in through the charger. Funnily enough, as soon as it's turned back on this way again, it will still say that it's on around 80% battery life. I have been having this problem for a while, but recently, the cuts have been happening so frequently, my phone is practically unusable when I'm going out anywhere.

Hi guys,

Found this thread by chance and it appears that many of you are or have been experiencing issues similar to my own… After having owned this great handset since January 14 I'm now lucky to get the best part of a day out of it without it randomly shutting itself down anywhere between 20-30% of charge. A full reset improves things slightly for a while but it doesn't last. I know there are software issues with the battery and Lollipop but I also suspect the battery is beginning to falter so I'm going to attempt a replacement myself. Slowly reading through these 30 or so pages but what are the highlights? Is there a way of checking the health or my current battery before I proceed? I saw the service menu mentioned on page 1 and I can get into it, I just can't find the battery test?

Any advice or pointers regarding the battery replacement itself would be great appreciate. I was hoping to get about another 6-12 months out of this phone before an upgrade.

Thanks.

Thanks for the swift reply! So what do I need in the way of parts/materials? So far I've got a new (genuine) battery, adhesive seal for the case - but is there not also stuff for the battery that needs to be replaced? I might also get a new back cover. Where does the NFC antenna sit, is it on the back panel or does it attach to the battery itself? Have I missed anything :confused:

I'm still trying to access the battery test menu just to check the current status of my battery, any ideas?
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Oreltub:
The nfc attached to the battery.

To remove it I used a blade to cut around it and put it on the new battery. Just be aware that there is two parts- 1 metal square and one copper colored square.

Fairly painless in the end, did it all this afternoon and I'm back up and running. Any advice on using the new battery? It was a brand new, unused, genuine Sony replacement. I've done the whole lot; tools, adhesive and battery for under £15 :)

I did have to cut the brown (assuming NFC) label off of the old battery though. They don't appear to mention that in any of the guides? If I get another year out of this handset now I'll be happy. Absolutely no resale value have they :(

Replaced battery, still having the problem.

Although generally the phone has been lasting a bit longer, on the new battery I have experienced cut outs at 60% and 82% with minimal usage since coming off charge 2 hours before. I really expected a new battery would fix it. Going to try flashing firmware on the phone now.

My wife's phone is having the same issue. Her phone has no warranty (its European model we got off e-bay (we live in the USA)). Does anyone know roughly what such a repair by Sony would cost.

Alternatively we are looking into just DIY. She has the lime-green model and really wants the replacement back to be the same color. There are tons in China, but that will take way to long to delivery, so we're looking locally. I saw this one, but it looks even extra cheap, no markings on it... (http://www.ebay.com/itm/Back-Glass-...231769?hash=item2353a5d319:g:aNMAAOSwY0lXR7gr) is it probably ok or should I look elsewhere? I don't know if the one's from China are better quality or not... I'm assuming none of them are OEM.

Has anyone gone the DIY route and managed to keep the phone waterproof?

dont by glass back unless you have a anti fall cover. I change my glass back at least 5 times. All got broke by a minor fall. The hing is: those fake back are glass but doesnt mean its scratch proof. mine got scratch and broke so easily that i decided to go back to plastic. Unless you buy the original glass from the japanese version.

But dont worry, this one from the link are obviously fake, but the logo are there, they just cant show it for whatever reason. mine was also like this.

There are videos on youtube that explain how to change back and battery. its easy. just take your time.

Waterproof is always a lottery thing. i wouldnt put my phone on water after this, even more with fake adhesive..

Had a talk with an old friend, an electronics engineer. He said most electronics today are made to last only a few years, as in menny cases consumers tends to upgrade their gear every 2nd year.

So if this is the case, it's also fair to assume, that there is no reason to include a longer lasting battery.

The cases of battery going fubar at an earlyer stage is just expected in a world of max profit.

Just strange the battery in my Xperia X10 Mini Pro still lasts a full day, used it for 4 years, before I got my Z1C (I must be the only person who only have had 2 smartphones, LOL).

[Xperia Z1 Compact Q&A, Help & Troubleshooting] Purehazard:
About 2 or 3 months ago, my Canadian launch Z1 started exhibiting issues described here and tried all the software tricks offered up to no avail. I got my replacement battery, adhesives and tools 2 days ago (Friday). Got them from eBay so I doubt any of it were original though the battery looked convincing even though the fonts were not 100% match.

I used a hair dryer to heat up the back (while burning my fingers on the aluminum sides...) and the rear glass came of easily. The second part was the tough part since the screwdrivers the adhesive came with were absolute garbage. I was only able to get 4 out of 9 screws off the mid frame. Luckily, 3 of those screws were the ones holding the battery in. I had to butcher the plastic battery chassis to get the old battery out and then trim bits of the new battery to fit it in. The back adhesive was obviously not original but I got it to fit and sealed nicely though I won't be doing any underwater tests.

The whole process took about 15 minutes.

It's kinda normal though I only had a chance to do one full charge and use it for just under 11 hours of mid to heavy usage before it hit 5%. There was a strange hiccup though. I just turned it on to browse via WiFi a bit and it dropped from 50% to 30% for no apparent reason. Otherwise, it's been fine.

I'll get a better feel tomorrow when I do my usual work day routine and see how the new battery fairs. All in all, not hard if you have the proper tools and even if you don't.
