2. Major Battery Capacity Increase – expect the 5.2-inch Galaxy S7 to get a 20% larger battery than the Galaxy S6 as it jumps from 2550 mAh to 3000 mAh. Samsung will also enlarge the Galaxy S7 Edge to 5.5-inches and give it a near 40% battery capacity increase from 2600 mAh to 3600 mAh. The former could be a big differentiator to the iPhone 7 if Apple doesn’t up its battery game, even this doesn’t mark Samsung’s return to the fully removable batteries of past Galaxy phones.
3. Expandable Storage Returns – the Galaxy S6 perhaps most controversially killed off expandable storage, but the Galaxy S7 will rectify that with support for microSD cards up right up to 200GB. This cheap way to boost capacity will place huge pressure on Apple to increase base level iPhone 7 storage from the iPhone 6S’s measly 16GB .
