5% drain on 10 mins FB is high. Even on 3G/H+ browsing, it is usually within 15-20%/hour on mine
With such a high usage, you probably have other apps wakelocks being in operation too. You can DO A LOT of things to reduce this high battery usage. Start by studying your wakelocks using betterbatterystats app

The main difference is in writing speed 6 MB/s ( class 6) vs 10 MB/s ( class 10)
Price difference is so minimal these days, why even want to buy class 6 ?

Perfect , no issue on these 2 sites with Chrome. The youtube videos played very well

Also perfect on 3G/H+ ( maxis)

Select it in settings/sound/music effects

Use water jet n spray on it

The bar level does not necessary means is weaker
Do a comparison using speedtest on both laptop n phone

This is a good MOD : you get expanded toggle listing in taskbar and just a simple Close ALL button to swipe away all open apps instead of swiping it one by one

No need. It will overwrite it

What powerbank are you using
All my HTC, Sony, Motorola, Samsung cables can charge . I am using yoobao 4800mAh n 11200mAh models

LTE elsewhere unknown n uncertain. I hope in next 2 years we can see more coverage
Once you experienced it you will hate the current 3g/h+ download speeds

Just disable it in settings/apps

All MSIAN versions are C6502 non LTE
Only AP sets C6503 are LTE
You can see it yourself from the box. LTE models has a big LTE sticker n check model number
We have several users who bought from Sony C6502 confirmed no LTE enabled

The Xperia z battery.life is decent
It is better than nexus4, butterfly trumps SGS2,SGS3, HOX
Of course cannot match note2
Just my experience using these phones
Its standby mode none of the phones I stated can match it. Battery level remains more or less static

Just tested posting to Facebook
No problems on mine
I use ASTRO file manager to post

I choose Facebook and not Facebook for Xperia

Use betterbatterystats next time to check what wakelocks causing this. Google what this app function n how to analyse the reports.
With 3g on, WiFi off My phone without fail every day overnight 7-9 hours the battery level if say at 100% Will remain 100%. There were only few days I got a reduction of 2-3%. I have been using this phone 3 weeks already. At 100% till now estimated standby time is around 4 days 20+ hours n this will reduce with battery level drop

I have absolutely no problems charging it using both my Yoobao YB602 ( 4800mAh) and YB 642 ( 11200mAh) . And I use different cables too ( i have so many types ) - sometimes HTC, Sony, Samsung and Motorola
I have another generic unit ( Slim Powerbank 20000 mAh - this one I do have problems at times - I can only use HTC, Samsung cables and it supplied cables to charge the phone. Anyway this is one lousy powerbank - it discharges off much faster than Yoobao and I doubt is listed 20000 mAh specs,. But no complains since is very much cheaper than the Yoobao

FAT32 limit is maximum 4gb/file transfer

Yoobao - I know there are fakes and mine is definitely original. Both has serves me well past 2+ years
As for the slim powerbank - it is only a cheap generic type ( cost me only RM 98+) and frankly I don't expect top notch performance either for that price. I bought it just to compare with the Yoobao. I will just throw it away the day it breaks down
