Battery For Samsung Galaxy S6 Edge
BATTERY Non-removable Li-Ion 2600 mAh battery
Talk time Up to 18 h (3G)
Music play Up to 50 h
The Samsung Galaxy S6 edge comes with a 2,600mAh Li-Ion battery, the same capacity as the Galaxy S4. Unlike the S4, however, the S6 edge battery is sealed inside. You can use the charger from the retail box to quickly top up the battery - 10 minutes charging for 4 hours of usage says Samsung.
The company has also enabled wireless charging, supporting the two existing standards. Qi has been used in Nexus and Lumia phones and even some McDonald's stores in Europe have charging mats. The other standard, PMA, is featured in certain Starbucks locations and is more popular in the US. The dual-standard support means it will be easier to find a place to top up your battery.
The Galaxy S6 edge Endurance rating came out to 73 hours, in other words you should get three full days of casual usage. With heavy usage you'll be looking for a charger (wired or otherwise) on the second day.
It posted some great times in the individual tests. In the Web browsing test the Galaxy S6 edge actually beat its predecessor by an hour for an impressive 11 hour run. Same with the video playback - a solid achievement considering the sharper screen.
Note that the S6 edge screen is slightly darker (200nits vs 275nits) than the Galaxy S5 at the 50% slider position we use for testing.
Anyway, at 20h the talk time is lower than the Galaxy S5 but it should hardly be a problem. The overall numbers come very close to the Sony Xperia Z3, which has a beefier 3,100mAh battery. It also beats the HTC One M9 and the Apple iPhone 6 by quite a margin.
