Re: Sony Z1 Compact battery drop

Hey Snip2La, 

 

That was really useful, thank you!

 

Decided to go for battery replacement but before that i just want to know how well is it performing in the Lollipop version?

 

PS: All this drain problem started after upgrading to Lollipop. Then I had spent some quality time and done the reseach on getting back to Kitkat and finally downgraded as well, but in vain. Battery performance is still the worse and experiencing sudden death and jump drains as in the Lollipop. So even Kitkat is no good! 

If your battery perfoms well in Lollipop, thats a great news!! Will happily go for the replacement!!!!

 

If possible, please attach ur battery usage screenshots with the new battery..

 

Your reply will be useful!

Re: Sony Z1 Compact battery drop

And yet, I find it strange how people can adamently state it only happend right after the Lollipop update. 

 

If that were true, I and my girlfriend also would be having these problems. But the battery lives of our Z1c's have improved significantly since the Lollipop update. 

 

Still, apps can sometimes be somewhat unstable so an update to Lollipop is definitely needed. But battery is OK. In 2 full days, it can go from 90% to as low as 3% without any sudden drops or shutdowns. 

 

Maybe there are batches of bad batteries that start failing at a certain age and, coincidentally, this is at the same time as the rolling of Lollipop.

Re: Sony Z1 Compact battery drop

Hi, same problem.

Why sony does not provide any feedback/support to all us ?

It is rather obvious that it is a hardware/software problem that the Sony company should solve. My phone is still on warrenty, and I do not want to spend my money to change the battery. Sony should do it. Any answer from the support team ?

I think that we are in the situation for a class-action......

Re: Sony Z1 Compact battery drop

This is user based forum - you will not get any official info here. If your phone does not work and it is still under warranty, send it to your local SONY representative for repair. But be aware that the battery life will not improve with the new system update. My friend done that and the phone -  although it works slightly better - is still a lot worse than before on 4.4.4.

 

And do not buy SONY anymore - theis should teach them a lesson.

Re: Sony Z1 Compact battery drop

I also certify. As soon as I replaced the battery - the problem went away, and the phone works very well. I bought it http://www.ebay.com/itm/PolarCell-Ba...item4d2e740b70
I can say that this is an excellent battery charge keeps better stock
The remaining 50% of the charge and the time display ~4hrs
What is the conclusion? We have got defective batch of phones? Or excessive heat kills the battery? It seems to me blame it all factors
We won the lottery Sony) But if such a lottery would continue, the situation will worsen for Sony

Re: Sony Z1 Compact battery drop

Same thing here it suddenly just drains from about 60% to 0% in a flash and shuts down. I ordered new battery. None of the other solutions helped.

Re: Sony Z1 Compact battery drop

Hey all,

 

Small update:

i did send my phone to Coolblue (dutch webshop) they forwarded the phone to Sony.

yesterday i got an e-mail that my phone was repared and send back home.

 

All within waranty. And it took only a week,

 

The repare note stated:

 

Translated.

There are several parts replaced.
The device is tested and works as expected

 

Dutch original note:

Er zijn diverse onderdelen van uw toestel vervangen.
Het toestel is daarna getest en werkt weer naar behoren.

 

i hope the box includes a more technical explanation of the "Several parts" that are replaced

 

but lots of credits to both Coolbue.nl and Sony

for taking my complaint serious and for solving the problem!

Re: Sony Z1 Compact battery drop

Hi, if you still need my advice.

 

I've never rolled back to kitkat.

Since replacement it works fine even on Lolipop.

I doesn't drop down, it's just live as much as you use it(like brand new just after unpacking).

There's new option in Lolipop "UltraStamina" (with limited applications and absolutely no data), I've used it once, xperia worked from Friday morning to Sunday night and had some power at the end))

 

On regular usage, I'm able to charge it once in two days.

 

Here are some screens(I didn't  tried to do its best)

No sudden death, and line is almost horisontal when Data is switched Off.
