Telsda / Worst mobile phone
I bought a Telsda T915 around 8 months ago. It was because it has dual sim function (can active both sims at the same time). So I don't need to being 2 phones on business trip. However, the battery life is extreme short, on a "busy day" it can last only for half day when 2 sims are activated. Worse of all, I found the battery started to swell up recently.
