“The HTC One M9 might actually offer shorter battery life than the M8, despite the fact that the M9 has 240mAH more battery than the M8.
Tweakers.net tested the HTC One M9. It scored lower than the HTC One M8 in both Internet browsing and video tests. In web browsing tests, the HTC One M8 lasted for seven hours and 10 minutes of continuous use, while the HTC One M9 died after 5 hours and 30 minutes. When it comes to video playback, the HTC One M8 lasted for 9 hours and 32 minutes, while the HTC One M9 only managed 6 hours and 8 minutes of life.
In a PCMark Android test that simulates daily activity, the HTC One M9 almost matched its predecessor by scoring 5 hours and 37 minutes compared to 6 hours and 5 minutes for the HTC One M8.
When addressing overheating concerns the other day, HTC said the phone is not running the final version of its software – in fact, the company supposedly had to push back the launch of the phone in Taiwan over software-related issues. As a result, battery life might improve once the final version of the HTC One M9 is released”
I really hope these results are just down to poor software, and will be addressed before its launch. Apparently Tweakers.net is similar to Anandtech. I am really tempted to cancel my HTC One M9 pre order, but I want to see these issues first hand before passing my final judgement.
