how did you glue the back cover again? Did you use an special glue or grip?
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
I used the adhesive that was included with the new back I purchased
[Xperia Z1 Compact Q&A, Help & Troubleshooting] alex_hk90:
Finally got round to trying to replace my battery.

Getting the back off wasn't too difficult - I didn't need any heat gun or hair dryer, just used the suction cup and guitar pick (starting at the top where there is a convenient gap and working round).

However, it looks like I might have been sold a dodgy battery, because the connector doesn't seem too solid (comes off easily compared to the old one) and when I plug it in to charge I get a flashing red / blinking red light. Searching online apparently that means a faulty battery. Maybe it's just the connector but either way not very helpful. :( Re-replacing it with my old battery it does start to charge properly so it's clearly something to do with the new battery.

Looks like I'll need to order another and get a refund off the eBay seller.

Are you sure that you connected the battery tight? Try again before replacing it..

[Xperia Z1 Compact Q&A, Help & Troubleshooting] alex_hk90:
I have tried a few times - when I connect the old battery it is fine, and when I connect the new battery I get the blinking red light. The connector looks a bit worn on the new battery, and doesn't have the spongy chip-looking thing on the top that the old one does. Also, it's much harder to get it to stay in place compare to the old one (which slots in much easier). I guess maybe it was used/re-used already and the connector is worn.

I've ordered from a different seller this time and am going to start the process of returning this one.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Oreltub:
My new battery don't have the spongey edge either, but it connected well..

You can try to connect the charger while holdind the the battery connector and see if it's a damaged battery or connector..

Good luck!

[Xperia Z1 Compact Q&A, Help & Troubleshooting] alex_hk90:
Thanks. Yeah I don't really want to be touching the battery or near it when it's charging, especially seeing that I suspect the connector is dodgy. I've sent a return request via eBay so I'll try again when I get my next battery.

Now the fun of putting the back cover back on.

EDIT: I couldn't be bothered to properly stick the back cover on using the double-sided tape, so have just clipped it on for now - seems like it will stay in place if I am careful when handling it.

Got my second replacement battery today and seems to have installed fine this time. :)

I haven't installed the replacement back cover yet, want to check it works for a while before committing.

To be honest I didn't need another back cover, the original one is fine. The only thing I would have needed is some adhesive (or double-sided tape) to stick it back on because I removed all the original adhesive in taking it off. Seeing as I have a new one now though I might as well use it - just need to decide if I want to try it with the limited adhesive behind the sticky plastic first, or go straight for the double-sided tape.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] abhijitcp:
so with no other solution in sight, ordered battery & tools from aliexpress. 45 days to India. Got it yesterday and replaced the battery, stuck on the NFC. i also pulled out the black sponge (on top of the connector) and stuck it to the new battery's connector. Total cost ~ ₹ 1,000/- (~$15). Not a bad deal, eh? 1st day of testing today...working fine so far. Hope the battery does well...
[Xperia Z1 Compact Q&A, Help & Troubleshooting] alex_hk90:
The replacement battery seems to be working well - it reported 50% when I turned it on, and has lasted over 24 hours. :)

Regarding the back cover, it attached fine without any additional adhesive (i.e. just using the stickiness behind the peel-off plastic cover). :)

[Xperia Z1 Compact Q&A, Help & Troubleshooting] Choriandus:
Hi everyone, I think I also have the same issue but with a Z3C. I have a few questions i would like to ask about this problem:

1. Which update started the problem? 5.0 or 5.1?

2. Did the problem started right after the lollipop update or 2-3 weeks after the update? Mine phone started acting up after about 2 weeks after the latest 5.1.1 update. It was good before (0.3%/hour. Now 1.2%/hour)

3. When the phone died at a specific percentage, does the battery suddenly drops a large amount of percentage to 1% and turn off automatically or it just died? (My phone suddenly dropped from 26% to 8%, then 1% 1 minute after and turn off)

I really don't want to believe i have a damaged battery :( . It seems like nobody on the z3c forum has this issue except for me.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Oreltub:
1. After lp update - 5.0.2

2. As you said, about 2-3 weeks after the update

3. Usually dropped from 30% to 0.. After some time it was also from 70 to 60 and such..

Xperia Z1 Compact .386 rooted
[Xperia Z1 Compact Q&A, Help & Troubleshooting] alex_hk90:
1. While it was after I installed Lollipop (5.0), I think that is just a coincidence and the battery would have gone even if I stayed on Kitkat.

2. A few weeks / months after, I don't remember exactly.

3. To 1% then off, if I remember correctly. But then when you reconnect the charger it immediately reports the previous percentage (e.g. 58%).
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Choriandus:
Do you have battery drain also? My phone drains constantly 1.2%/hour with everything off in both Kitkat and lolipop (when gsam battery says it was in deep sleep 99% of the time)

When i plug my phone it shows Sony logo then turns off, about 1 minute after that it shows 1%. I really hope it's just a battery calibration problem. Anyway, i'm flashing lollipop right now and I think I will have to return it if the battery doesn't improve. It looks like Sony's lollipop is messing a lot of phones. Some people in the M5 forum are also talking about the somewhat similar problem.

Many people in the official Sony forum site are also complaining about the battery drain but I'm not sure if they have the similar problem.

I still can't understand how an OTA update can physically damage the battery :eek:
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
I think it's possible that the update didn't cause it and it was just timing or something.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] Choriandus:
That's also what i guess but if the battery degrades, I think it should degrade at a slowly rate, not suddenly drain 4 times faster like that.

It's an excellent phone apart from this plague.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
Perhaps its a threshold thing. At a certain point of degredation it just stops being able to supply enough volts and that's when everything fails.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] alex_hk90:
I think you're right - I only replaced my battery a couple of days ago but so far it's completely solved the issue I had. :)

Given this happened to the battery in my old phone (HTC Desire) after a couple of years as well, I'm going to try to change my battery charging habits to only charge it when it's already mostly decharged (under 50%) and then make sure I unplug the charger when it's at 100% (previously I would leave it charging all night, which probably wasn't great for the battery charge cycles).

Hi guys, new record with my Aliexpress battery
[Xperia Z1 Compact Q&A, Help & Troubleshooting] spiwar:
im facing the same problem on my c6902. It's like you D5503 users but even worse.

It would jump of from 100-97% to 0% if i was playing real racing 3 for like 5 minutes (sometime it doesnt even lasts 5 minutes)

100-73% to 0% if I was doing less heavy tasks. The back of the phone popped a bit (not too much but just enough for me to put my nails in) and I think I can easily pull the back out with my hands if I tried.

I suspect this is the battery getting swollen? Do I need to replace it asap (for safety reason)?
[Xperia Z1 Compact Q&A, Help & Troubleshooting] einfachgaer:
If the back of the phone lifted because of a swollen battery, yes you should indeed replace it asap.

Just replaced mine. I got new adhesive and re-used my glass z1f back cover.

I had to trim it up with an exacto knife. Back together, powered up and recharging.

[Xperia Z1 Compact Q&A, Help & Troubleshooting] crimson12:
I mean chances are yes it'll lose it. It all depends on how good you are at reattaching it and how much you trust the vendor you bought the parts from. I just assumed mines not waterproof.

Will also confirm that a replacement battery is the only way to fix it. Done today for $59 in Melbourne Australia on the spot(took about an hour at a place called repair mate). All fixed and two system updates waiting (was already on lollipop). And 32 app updates....so stress tested and working fine again like new.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] allofmex:
Another solution experience:

My Z1 compact was still within warrenty time (one month left) so I sent it to sony service center. They replaced the battery. Now all fine again.

Take a note:

My phone had an unlocked Bootloader and was rooted. So even if you unlocked you may use the sony service on this battery issue! No Problem.

(Valid for Germany) Fill out the Service request form on sony website http://repair.sonymobile.com/ , they will sent you a deliveryservice label. It took less than a week from bringing to post office until I had it back. Well done Sony :good:

Another Info: My phone never saw higher Android Version than 4.4, so the problem is not related to 5.x Update.

Hi,

I also have this problem, I really can't believe it's NOT the update. I had the phone for a year and a half, then dropped it and cracked the screen, it was insured so I sent it for repair.

I got the phone back, but with a different IMEI number, so that means a new phone.... Doesn't it??

Then 5 months in, new update and then battery problems..
[Xperia Z1 Compact Q&A, Help & Troubleshooting] alex_hk90:
A different IMEI number means most likely a different (not necessarily new) phone, yes.

If you sent it in for repair it's likely to have been a refurbished phone they sent you so the battery may have already has substantial use.

Also, people have had the issue without the update:

[Xperia Z1 Compact Q&A, Help & Troubleshooting] Brillenschlumpf:
Hi

My phone had the dying issue first time a year ago. It was still covered under warranty then, so i sent it in and got it fixed. I wasn't told how or what they fixed.

Now, 2 months after the warranty went out, i had the issue with the phone switching itsself off without warning again. The phone just would switch off and could only be restarted when plugged in to a charger. The charger could be removed after starting the phone up, just like a starting cable between cars. The phone showed stable around 70% battery capacity, but still would switch off suddenly without good reason. I watched streaming videos on it, battery drained at normal speed. then, when putting the phone down or walking around with the thing in the pockets, it would switch off again. So I found this thread and ordered a new battery on ebay.

As the battery is supposed to arrive end of january, and I cant find the charger for the ancient flip phone that was laying in a drawer, I decided to test how difficult the opening process would be. Not difficult. Hairdryer did a fine job warming the back panel, and I used a credit card instead of the special tools to lever the back plate off. I happened to have a tiny torx screwdriver and removed the 9 screws and the plastic frame inside after warming it up with the hairdryer again. Battery looked just fine, no bulges or anything. Battery test in phone also said "no need for changing" in the service tests.

So the battery is connected with a tiny tiny plug. Well, maybe there could be corrosion on the plug? Or the counterpart on the phone? I used a drop of contact cleaner on a cotton swab and rubbed the swab carefully around on both connectors. Then I reassembled everything again and well, the phone is working again. No more random powerfailures. Wipe contacts, not cache.

Conclusion:

You plan to buy a new battery and will open the phone anyway. It is NOT difficult. Just try and clean the contacts before you order the battery. I had "corroded" contacts also with other mobiles with removable batteries in the past. Cleaning them helped then, too, so it was not surprising that it worked here as well.

Good luck!

....too late to cancel the ordered battery....well...will look nice on the tree next year....

Update January 2016:

Happiness lastet not too long. The phone started with erratic shutdowns after a few days again. I have changed the battery for a week ago and did not have any trouble since.
[Xperia Z1 Compact Q&A, Help & Troubleshooting] ElvPo:
After reading a lot on the web about this issue, upgrading to lollipop and then battery drops/drain and finally finding this topic I can say that replacing the battery has helped! I did everything as discussed at other places ie downgrading, factory reset, all kinds of settings and more blabla, the only thing that truly helps is indeed to replace battery. Thanks everyone for confirming!

I bought mine for 19,95 euro, a sony one, got it the next day, replacing took about 10 minutes, charged to 100% while phone turned off and voila, phone lasted for 2 and a half days and still has 35% left. So anyone reading, yes, yes, yes, replace battery!

Another z1c user here with the same issue. Phone is nearly two years old. I was running munjeni's KK 4.4.4 D5503_14.4.A.0.108 ROM without any battery issues for a long time but decided to try more recent LP ROMs (CM and MX) a few months ago and soon after I started having the "vertical" battery drains and sudden shutdowns. It sad because the phone is otherwise perfectly usable and powerful enough for everything I need it to do.

Did anyone try these measures suggested here?

http://talk.sonymobile.com/t5/FAQ/Facing-problems-with-abnormal-battery-and-shutdown/td-p/320375

It does not really explain very well what the point of it all would be but it does at least seem to expose some issue. I can charge my phone to 100% when shut off. Next time I load Android, it also shows 100%. If I then do a force shutdown and reboot, the Android battery indicator only goes to about 92-94%. If I then do a forced shutdown again and charge while off, it will start at about 90-91% and charge up to a 100%. So there does seem to be some discrepancy between perceived charge and actual charge also here. However, repeating this cycle a few times does not show much signs of gradually "filling" some unused capacity of the battery, so I do not think there are any chances of healing the battery by doing this, at least not in my case.

One of the reasons I am still hoping for an alternative solution is that I am using a textured sticker cover (EasySkinz) on the back of my phone and I do not think a suction cup or hair drier heating would work as expected without removing it first. It would likely not fit well again if I remove it. A small issue and specific issue I know, but...

Is the general opinion still that the issue is a faulty battery and that only a new battery will help?

Total frustration towards Sony. I hope I haven't ever bought a phone with non-removable battery. My Z1c with its phenomenal battery life is now accompanied 24/7 by a power bank, in the fear that I'll have a sudden battery drain and be left without a phone in the middle of nowhere, especially during an emergency situation. Looking already for another phone, and after I replace the Z1c as a main phone, I'll send it over to service. And after I receive it back, I don't think that I'll ever trust its waterproofing.
