Have I failed to read correctly.. or is there really no TPU test on how long the battery lasts in various conditions of use?
Razer quote 70 hours - but having owned the Mamba 2012 from them last**, the battery while gaming certainly does not last anywhere close to the specified time quoted. 16 hours gaming was quoted; 5-7 hours is what you'd expect to get from it.
Using my personal experience as a basis for this new Razer product, I can only assume the 70 hours quoted are on "stand-by" mode (aka turned on and awaiting user input) and will be significantly less while browsing OR gaming.
But, alas, it is still a good review.... however... buyer beware.
**and not another product after because it was so awful and failed to live up to what it claimed in just about every aspect - not just battery life - including usage distance.
