I think you're better off just moving on and getting another battery. I got this one and it was certainly new but I doubt it's actually a genuine Sony part. It's worked fine for me since I installed it a few days ago.

http://www.ebay.com/itm/111734404944

If your Z1 is rooted, you can use a battery calibration app to, well, calibrate the new battery. If you don't have root, try the long way around.

Anyways, good luck.

I've rooted Z1 but battery calibration seems to be completely useless in my case
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
That's because it's pretty useless in 99% of cases anyways.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] mijorus:
Hi guys, same problem here. I had the same problem and I did a battery calibration following the instruction I found here on XDA(wait till 100% and leave the phone charging up for 2 hours) . Now it's a little better, battery life is still worst then two years ago but at least I've the battery alert in time to recharge my phone. However I bought a new battery and I think will replace it when the new one arrives. Have you found any troubles when u tried to replace the original battery? :confused:
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
The calibration is placebo for the most part. However if you follow directions either in the OP or on YouTube you shouldn't have any issues replacing the battery.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Purehazard:
Just make sure the screw driver fits properly. The one I got from eBay was garbage.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] giriz1c:
My battery just became normal. :laugh: No draining issues. Month before I had same quick draining issues. In my case this quick drain was because of many background apps which heats up battery then I switched off my phone until it gets cool then I Factory reset my phone and cleared internal storage then flashed new ROM then my battery started discharging normally...so before buying new battery just try this once.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] mijorus:
Why? Do you need a special screwdriver or something?
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Purehazard:
The screws are tiny torx type but the ones at got with my adhesives did not grip properly.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
This thread isnt about the battery draining quick. It's about it dying instantly. Your issue was clearly different than everyone elses.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] mijorus:
Yesss, I replaced the battery as I said and now my phone is back to its original glory. 4h display-on time with wifi/4G connection always on. I bought a "new" and "genuine" battery from ebay and its working fine. Open the back cover was even easier than what I thought. If your phone dies suddenly, I really suggest you to go for a self replacement : it is cheap and will solve all your problems. Cheers
[Xperia Z1 Compact Q&A, Help & Troubleshooting] giriz1c:
No, i mean even I had phone dying suddenly issue...my problem was similar..when battery percentage was 30% then suddenly it shows 15% and gives warning,then suddenly it shows 3% and 0% and phone switch off. Sometimes from 15% - 0% and shut downs.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] New Folder:
The battery controller should not let battery voltage drop or raise above certain point also leaving some reserve mAh in to prolong Li-Ah cells life.

This controller malfunctions and somehow mets conditions that battery is emty therefore shutting phone down while in reality it's not always the case.

It would be interesting to see if this theory is true but unfortunately i don't have corrupt battery to compare the hex with new one.

Most probable cause Sony again had bad batch of batteries where someone obviously slept on duty since this happends only with select lucky ones.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] xiaokinsei:
Hi all,

I have replaced the battery about 2 days or less.

Eventhough the problem (since mid/late July) of it suddenly dying went away, the amount of battery time seems to have diminished quite a lot compared to before all this problem started.

Currenty, at 100%, power management will tell me that it can only last for 4 hours (or 15 hours in stamina mode)

So when I saw this, I had factory reseted the phone, and it tells me it will last me 1 day 22 hours on stamina. (I can sort of live with this since it is better that what it was giving me) I then had restored my data.

I had the battery drained to 0% last night before charging it. When I turned it back on it went back to the previous power of 4 hours / 15 hours stamina.

Phone Info:

Android version 5.1.1

Build number 14.6.A.1.236

Has this happened to any of you or is this the new battery's problem? Any ways I can fix it to return to its previous battery glory?

Any suggestions are much appreciated.

I have read through all the pages of this post.

It sounds like you either have a different issue with your phone, or your new battery was dodgy.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Swaddy:
Well I had these battery drops as well. First I thought it had something to do with the battery calibartion myth. After taking my phone out of its case, there was a gap between the silver and the black part: ah, so the battery blown up a bit and it's definitely broken.

I ordered a new battery and glue and replaced it. Now I got 4h screen on time again and it feels like new :) Sadly now it wont be waterproof because the whole case burst a little bit.

In the end I'm happy about my past self that bought a phone that has the possibility to replace the battery, even if not that easy
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
To me this really sounds like you have a rogue app. If it's fine before you restore your data it's probably not the phone's hardware. I'd try installing apps one at a time and see if you can pinpoint which is using a lot of resources. Just to clarify how are you restoring your data?
[Xperia Z1 Compact Q&A, Help & Troubleshooting] xiaokinsei:
I have tried to factory reset the phone, with the 'back up & restore' app and the issue of the drainage continued. (I've also tried this method before the change of the battery)

So then the last time of reseting the phone, I decided to use the Sony PC Companion without restoring any data from the back ups; which indicated of 2 to less than 3 days on stamina after the reset.

You may be right about a rogue app. After re-installing the previous apps from Googleplay one at a time, after draining the battery, the battery indicates of 1-ish days of battery on stamina. I'm tired of reset/restore/install that I'm going to leave it as it is.

I rather live with the short battery life because it's not dying on me at 98% battery like before. What I have noticed was the battery doesn't heat up greatly like it was before the battery change.

It could still be a bad replacement battery that I purchased from eBay like alex_hk90 said, but waiting for another month isn't something I would like to do again.

Thank you for shedding some more light on what the other issue(s) can be. :)
[Xperia Z1 Compact Q&A, Help & Troubleshooting] sniperspa:
Just to confirm you all that with my second battery substitution i solved the problem.

It's clear that the first battery bought was a used battery....the battery now is perfect like a new z1c :)
[Xperia Z1 Compact Q&A, Help & Troubleshooting] lololol13:
Same problem here:

When the phone has to do some tasks with higher CPU usage (updating some apps with Play Store, benchmarks, watching videos...) the battery drops from 50% to 0% within a second.

Brought my Z1C to a shop which replaced the battery, but nothing changed.

Even a full wipe and installing the stock ROM didn't help.

Any suggestions?
[Xperia Z1 Compact Q&A, Help & Troubleshooting] templeka:
Like the previous person above you, they probably gave you a bad battery.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Bugnaz:
Same problem - new battery fixed it. Back cover won't stay on now ~

I was wondering if people had any experience with glue, and which type would be good to use to seal the back cover on?

I noticed that some people made negative references about using super glue - but I don't specifically recall what the issue was.

~

I've read though the whole thread, and I found that by following the useful links people provided I was able to buy and fit a new battery. Main problem finally solved, thanks :D

My particular thanks to whomever made a point about having no skills in the "battery replacing area" and yet they did it easy peasy, thank you. That actually inspired me.

New battery was cheap, and easy to replace.

I don't think the tools are really needed, I only needed the small Philips screwdriver (which I already had) but it gave me confidence knowing I was well tooled up!

I got a new back cover as I wanted to ensure I had fresh "stick" to get my phone as close to "new" as I could.

Unfortunately my new cover isn't very sticky and I'm having trouble keeping my back on. It keeps falling right off. I've heated the new cover to increase the stickyness then left it clamped with 6 clamps for a few hours - but it still fell right off. Current temporary solution is to put a bit of electrical tape around the bottom, as it's the only area that isn't in use as screen or camera.

My new battery didn't have the small rectangle of foam on the back on the connecting pin part that my old battery had - so I just removed the small bit of foam from my old battery and popped it on the back of the new connector pin (I'm pretty sure it's there just to fill the gap and guarantee the connector doesn't disconnect.)

The NFC square part was fairly easy to remove, although it did leave behind a few small pieces of black backing. I also has to use a bit of old "stick" from the old back cover to help hold it in place on the new battery.

I don't use the NFC function so I don't know if that worked okay.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Purehazard:
I bought a set of adhesives for my Z1. They came sticking together a little but I managed to salvage enough to make it stick properly onto my existing back.

I suggest you buy a couple of these, extras just in case one is messed up.

Those adhesive never worked for me. Someday they gor loose. That actually happened several times.

I used super glue and i dont mind it. Just be carefull applying.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Nash123:
Same here. Had to use super glue after some time.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Bugnaz:
Thanks for the replies so far.

I've just ordered a couple of the replacement sticky bits ~ but if they don't work I shall try superglue around the edge.

I'm wondering if heating up the existing glue on the phone back will help. I did originally try this before reattaching the back cover, then clamping it overnight ~ but now I'm thinking that instead of getting the glue "warm" I should heat it for much longer and get it actually hot. See if it molds and fixes better after a really good heating.

I may also try this with new sticky bits, before trying the super glue too.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] profyler:
i dont think it will change. Do like I did. use the adhesive but also put some super glue. Small portions aroung all the back, not just corner.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] mikeguima:
Hey!

So, I seem to have a similar problem. My phone now reports around 1d 18h of battery at 100% and drains down pretty fast after a certain %. I've looked up online and figured it would most likely be a software problem. I repaired the phone using PC companion and it actually seemed to reset the battery because it then showed 3d 15h or so of battery life at 100% which is more or less what it has always shown. However, after I started using it again, for some reason, the issue reappeared and now it's back to the drain problem and only displays 1d 18h of battery at 100%. I've tried resetting it again but with no avail this time.

Does anyone have any solution/ suggestion?
[Xperia Z1 Compact Q&A, Help & Troubleshooting] karamancho:
don't obsess over meaningless stuff and use the phone like a sane person. if the battery lasts you a day of heavy use or two days of light/moderate use then keep the battery, if it drains faster than that replace it. as simple as that.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] mikeguima:
It's a software problem, the battery used to last longer. And actually, I've been trying stuff in the meanwhile, and I think I found the problem... Google play services... Or anything else in the updates.

I resetted the phone again, blocked the wifi connection and voilá, it indicated 3d and something of battery again in Stamina mode. Then started the updates (including Google Play Services) and the phone instantly shut down and only displayed 1% of battery when I turned it back on (from 60% or 50% something it was when updating). Therefore, I surmise the problem is with those google play updates. Now I just have to find a way t solve that.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
Yeah lets ignore 35 pages of posts literally showing you're wrong. It's not software. It's a hardware issue with the battery. Both the OP and others before you can attest to that.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] mikeguima:
Provided my case isn't different. Acutally, remeber it was at 60% something, then shut down as soon as as unistalled google play services and was at 1% when I rebooted it? Well, I've just unnistalled google play services and guess what, it's back at 60% again. Definitely sounds like hardware. I've seen others with similar problems with google play services. I'm not trying to say other are wrong, but my problem definitely seems to be software.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
Sorry that came off really mean, **** day at work. My bad man. If its something different I'd recommend making a new thread. Still could be hardware. If the battery isn't correctly supplying the right voltage to the phone you can get very random shutdowns that don't entirely correlate with percentages.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] karamancho:
what part of my (fairly short) post did you not understand?
[Xperia Z1 Compact Q&A, Help & Troubleshooting] mikeguima:
What part of mine did you not? Battery being at 60% displaying normal battery life, then suddenly going to 1% after I installed Play Services, then back up to 60% after uninstalling it? Does it sound like I need a new battery? Does it? Jesus, you guys sure are agressive here.

[Xperia Z1 Compact Q&A, Help & Troubleshooting] -totonio-:
First try to see if your phone connects in fastboot/flashmode, plug the USB cable while pressing vol up, if you see a blue led probably it's the battery, if not it could be the motherboard

Fell so sad, i think it could be the motherboard then. There's no chance to enter fastboot mode. No respond at all. I had tried to enter fastboot mode once i figure out the device was dead, a couple times.

Then i am pretty sure now i have to get a new one as my second phone

Exact same problem. I had thought that I may be the only unlucky one, but seems that many people are facing same issue. After upgrading to Lollipop, the battery life of my Xperia z1 compact had reduced to almost half. And now this problem of phone shutting down mid way while doing some thing. It is frustrating as you are not even warned. Has the software issue now actually damaged the battery? I am out of warranty now :(

I replace my battery yesterday. Working great. Maybe not great as original battery but all become normal back. So, my conclusion if problem like this...better go change new a battery.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] djfuego:
Solution time guys.. :D I have managed to re-charge to 94% by doing the following..

Start by hard Offing (Hold off and vol up until 3 vibrations) with usb plugged into your Power adapter (Not Computer)

leaving the phone for about 5 mins at a time to see if the percentage has incremented..with the charging icon.. just tap the on off button to show the charging indicator.

The percentage has not gone up or the charge icon is no longer animating then I do a hard power off again. (Hold off and vol up until 3 vibrations) the charging icon will start flashing (Charging) again from where it left off...

Keep going until you get to 100% Might take a few hours.. As its taken me most of the night to get this far I'm confident it's working as I'm at %94 but could only get to %82

The Battery charging icon flickers now and won't go past this.. better than it was..

If you run the battery down to the hilt then you will start getting charge problems. I guess this might be to the age of the battery or more likely something to do with the lollipop update as I never got this issue with kk 4.4. I'll wait for the Z3+ Compact (Fingers Crossed) either way..

instantenious battery drop, sudden death Xperia Z1 compact on CM12.1

My battery daily dies between 55% - 70% battery level. Battery percentage drops to zero in a few seconds (I seen it happen sometimes, but also from battery stats), phone shuts down. This happens ever since I rooted & installed cyanogenmod 12.1 (that was a week ago, now updated to 12.1-20150601-nightly-amami), never ever before on the stock ROM. Tried battery calibration tools, battery charging over night, battery charging with phone off, freezing all but system apps, websearches.etc. So I have to keep it plugged more than daily

An old phone once had problems like that, disconnecting battery did the trick, but that's not possible with Z1c.

Can it have to do with bootloader, fastboot? Hardware failure would be an incredible coincidence. I'm running out of options. What should I do?
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
Do you think it could be possible to open the back of the phone, disconnect the battery cable and reconnect it?
[Xperia Z1 Compact Q&A, Help & Troubleshooting] jazzdick:
Yup I did twice a few days ago. Once with almost empty battery, once with full battery. Left battery out for half an hour. No change. Left SD-card out, no change. Yesterday I saw that battery voltage (from 2-Battery app) was 3.6 V just before forced shutdown (9% and sharpely dropping to zero). I'm wondering if 3.6 V is a normal shutdown value. And how it works: how is the rating of battery status calculated (in %)? The voltage?
