Battery size reduced on XZ

[suarez1]

wwhen i first bought it and tested its battery, it was 2980mAh, but not after only more than 1 week, it was down to 2800mAh. IT can't loss capacity so fast, is there some problem with my XZ?

Look at the iFixit video for the XZ. To replace the battery you need to first remove the motherboard.

Interesting, do share the link, thanks

My mistake, I thought it was the XZ but the video is in fact for the Xperia X. I obviously can't be sure but I expect that the XZ is very similar internally. The X came out in May and the layout of speakers and buttons looks identical.

You shouldn't assume, I haven't seen any teardown of the Xperia XZ, I could assume it's the same as the Xperia Z series, but that's not accurate, we'll have to wait for someone to take it apart, also, taking a phone apart it's not a big deal, if you want to replace the screen of most smartphones you will have to remove pretty much every component. 

Side note, I've done it with different Xperias.

My battery is in good health no problems
I used it about 3 weeks and its still 29800 mha,,,

I think you need to do the battery test when it's fully charged.

Nope, had about 40 % and it showed the correct mah.

The only situation where you need to have battery fully charged is when doing a battery calibration, remember I did that on my good old note 3.

Hi @suarez1121212,

Could you elaborate on what you mean? For which reason would you like to reset the battery, and what do you mean by that more specifically?

Let me know some more details and I'll do my best to assist you!

When checking the battery capacity using *#*#7378423#*#* code i noticed that it was reduced to 2k6 mAh after only MORE THAN 1 WEEK USING. I'm so disappointed with XZ battery so i decide to reset its battery to see if things get better
