Are smartphone manufacturers finally taking complaints about battery life seriously? A new rumor posted by Dutch website GSM Helpdesk suggests that Samsung is. According to the website’s sources, Samsung is testing out a version of the Note 6 that has a giant 4,000mAh battery, which would be a step up from the Galaxy S7 edge’s 3,600 mAh battery. The website also claims the device will have a 5.8-inch display with a resolution of 1,440 x 2,560 pixels, along with 6GB of RAM and 32GB of internal storage.

But let’s be honest: What’s really intriguing here is the giant battery.

As we mentioned before, the Galaxy S7 edge pushed things forward earlier this year with its 3,600mAh battery. HTC’s newest HTC 10 flagship phone features a 3,000 mAh battery, but HTC claims that it’s developed technology that will allow it to last up to two days on a single charge. And last year’s Droid Turbo 2 featured a 3760 mAh battery, although that device was more of a niche device that was an exclusive to Verizon.

So a 4,000mAh battery would really be pushing things forward here, especially when you consider that the Note 5 “only” had a 3,000mAh battery. Does this mean we’ll soon expect all our phones to at least last for two days on a single charge? That would obviously be terrific but we’ll have to wait and see.
