несъ&#1105;мный акку&#1084;улятор - means non-removable battery
In the original Russian article it says that the battery is not removable. It's an obvious Google Translate error.
it's not impossible, the previous HTC One (M7) has non-removable battery and unibody design, but the Dual SIM version (HTC 802) has removable back cover.
I don't think that is a translation error...because the last model htc one (M7) dual sim had a removable back cover despite the single sim model
Russian is my native language, so I can confirm that the part about battery being removable is indeed a translation error, it is listed as non-removable in the original article. Also, specs listed are from regular M8, later in the article it is stated that no info on dual sim version specs was available.
