i see that china phone have the potential to be so much more than they can be but there is two flaws they have... weak batteries and no upgrade support. if those two some how another company gets this down.. china phones can take over.. or in other words. no reason to buy those expensive phone. personaly ive bought THL phones and only thing wrong is the battery.
I would not say the China phone has a weak battery. I had 720p MTK6589 phone and could use that phone for 8 hours on screen. Part of the problem is 1080 LCD which takes a lot of juice to move that many pix. The ARM GPU is just not efficient at doing it.
Which model you have that didn't have good battery life. And how much on the screen time?
Normally the popular model have several upgrades of the ROMS.
Biggest issue with China company *manufacturer*shops*factories is - communication, honesty, accuracy.
