Galaxy Note III: Larger Battery and a Dual-SIM variant by Samsung?
The Samsung Galaxy Note series has long been known for its very good battery life and this is one of the biggest advantages over other released smartphones with the mobile operating system Android by Google on the markets.
The first Galaxy Note by Samsung had a 2500 mAh battery, the second device of the Note series, the Samsung Galaxy Note II, already featured a 3100 mAh battery and according to a new emerged picture (was sent to the guys of PhoneArena) and this picture is said to show a prototype of the upcoming Samsung Galaxy Note 3 (Note III), the new Android model of the Samsung Note series, the Note III, will probably feature a 3450mAh battery.
One is not able to exclude such an information about the upcoming Samsung Galaxy Note 3 because also the other technology in the devices is getting smaller, apart from the displays of the new smartphones with the Android OS by Google.
The new Galaxy Note III by Samsung is said to feature a 5.7-inch Display, including the current best Super AMOLED HD-technic by Samsung – beside the new software features of Samsung’s TouchWiz UI and Framework.
In addition, a Chinese company has recently proved that such large batteries fit into smartphones now due to the other parts in smartphones, which are getting smaller from year to year. The Chinese company Changhong has announced a new smartphone with a 5.5-inch display, which features a 5000mAh battery while the depth of this new device is just 9 mm.
However, the alleged new picture of the Samsung Galaxy Note III must be regarded with some scepticism because the image of the alleged Galaxy Note 3 shows two slots for SIM cards and it is very unlikely that we already see pictures of a possible DUAS variant of the Galaxy Note III by Samsung.

So, it is a bit questionable whether the picture does really show a recent prototype of the new Galaxy Note III of the known smartphone manufacturer Samsung. Of course, the Galaxy Note 3 by Samsung will certainly feature a bigger battery than the Note-model of last year, but one might expect rather a 3300 mAh battery than the mentioned 3450mAh battery.
These batteries dont last more than 4 hours. Thatd why you to have a power bank and guess what mate, I just happen to be selling it.
