Got me a Sony Xperia C5 Ultra Dual SIM to replace a similar T2 Ultra. Okay na rin naman sana yung T2 if you only need basic usage out of your celfone. The limiting factor eh yung 1GB RAM + 8GB storage. After a while wala ka na ma-install at laggy na rin.
The C5 Ultra upgrades the T2 with a bump in resolution from 720p to 1080p of the 6" screen. Nasanay na rin kasi ako sa phablet so yung 5.5" still looks smallish to me. RAM is now 2GB with 16GB storage (expandable via microSD). LTE na rin siya from the previous 3G. The front 13MP selfie cam with wide lens now has an LED flash also. All that for only Php15k+.
Since bago pa I am almost always tinkering with it. So I really haven't tested how long the battery lasts with normal usage. With lots of texts and browsing it lasts me more than a day naman.
