The closed build of the HTC One (M8) means that its 2600mAh battery cannot be hot-swapped. This means travellers, professionals, and heavy users will not be able to carry a spare internal battery.
You can use Power Saver mode, 'Extreme Power Saving Mode' (a feature that is not yet live on Australian devices, but is expected to be launched via an update in the coming weeks), and the likes of the Qualcomm Battery Guru app, but it's important to remember that these can only do so much, especially as batteries deteriorate over time.
Those of you who need a few days of juice between charges will have to either look elsewhere (including the Samsung Galaxy S4 or S5) or purchase a charging case or portable charging unit.
The HTC One (M8) has a bright and crisp 5in screen with a 1080x1920-pixel resolution, giving it a market-leading 441ppi density. Text is crisp but not too sharp so it makes for comfortable long-term reading, emailing, messaging, and social networking. On the other hand, its colour reproduction is not quite as vibrant, dynamic, or rich as that of the Sony Xperia Z1 and Z1 Compact, Samsung Galaxy S4 or S5, or the LG Flex. Depending on the media type and quality, blacks sometimes appear slightly washed out at times, too. Dropping the brightness to about 80 per cent fixes the latter, but that means losing overall visibility in well-lit environments.

The HTC One (M8) has a 4MP rear-facing 'Ultrapixel' camera, and a second rear-facing camera for depth detection, but this doesn't always get photos over the line. It's hard to say that the smartphone's camera is especially good or bad in any situation because results are really hit and miss.
There were situations in which we captured extremely detailed and clear landscapes full of colour in naturally well-lit environments, while other photos within the same conditions product an abundance of image noise. The same was the case in dim environments; on some occasions subjects in our photos were better lit than in real life (in these situations the phone blew its competition out of the water), while other images were overwhelmed with graininess.

If you're a snap-happy user who needs a phone with a reliable camera that produces consistently high-quality photos, it's best to stick to the likes of the Nokia Lumia 2010 or Apple iPhone 5s.
