As per what I have read so far, the technical details of Samsung Galaxy S4's battery is of 2600mah only, which is lower in comparison to Galaxy Note 2. So, definitely the battery life is going to be in middle of the Galaxy S3 and Note 2 devices. It would have been better if Samsung could have provided some more battery in this new phone, that shall have impressed everyone. What do you think, whether this much of battery life and so much new features, will the Galaxy S4 last longer, and if so till how much hour is the main important question. Otherwise, we will simply need to carry an extra charger all the time, like for example the Pico Portable Emergency Phone Charger.
