Bombardment Life

Packed into the HTC 1 M8 is a 2,600 mAh iii.viii V battery for a total capacity of nine.88 Wh, which is 13% larger than the HTC One M7. In HTC's documentation for the all new One, the company claims this battery tin terminal 40% longer, which is an interesting merits considering the physical difference. This departure could be attributed to the more than power efficient Snapdragon 801 SoC, or improvements in brandish applied science, but it's something I'll exist testing.

By and large I experienced amend bombardment life from the One M8 than I did from the M7. With typical usage I would end a solar day with around forty% of the juice remaining to exist used, which is a decent upshot. This is comparable to what I achieved with the Sony Xperia Z1 and its xi.4 Wh battery, but not as good equally the LG G2'south highly efficient usage of its own 11.4 Wh battery contained within.

The HTC One M8 packs two carve up ability saving modes. One is the standard power saving mode, which conserves CPU usage, reduces brightness and kills the data connectedness when the screen is turned off. It can save bombardment life where necessary, only it doesn't provide massive gains.

The other is the Farthermost Power Save mode, which as its name suggests is a much more severe way to conserve bombardment life. When the feature is enabled, everything else is disabled, giving y'all access just to the essential features of the phone: calls, letters, electronic mail, calendar, and the calculator. Past transforming the device into a souped-up feature phone, HTC claims you tin get up to 30 hours of life from just 10% remaining charge.

While the feature definitely seems cool, I couldn't test it because it wasn't actually installed on my test unit. HTC assures me that the characteristic will exist made available to devices worldwide through an over the air update, so don't be surprised if information technology isn't on your HTC One M8 out of the box.

Starting with this review of the HTC One M8, we're adding to the set up of battery benchmarks we run on devices. I've been building up a ready of results over the by few months then we tin can compare the M8 to some other devices currently on the marketplace.

In this examination we're looping a total refresh of the TechSpot homepage at a 90 2nd interval (which simulates reading lengthy webpages like this review). Brightness is gear up to l% and the SIM carte is removed so cellular networks aren't used. Most devices seem to perform well in this particular benchmark, and the One (M8) is no exception. If you're reading many web pages on the device, expect pretty proficient battery life.

In GFXBench's battery test, which runs a loop of the GPU-intense T-Rex HD test thirty times at l% brightness before extrapolating how long the telephone would last, the HTC One (M8) performs pretty disappointingly. What could be a culprit here is HTC'southward criterion cheating code that bumps the CPU upwardly to 2.5 GHz regardless of the CPU load, which naturally volition bleed more battery than necessary if the CPU isn't beingness used at 100%.

If companies didn't cheat in benchmarks, maybe they would perform improve in tests like this. Sometimes information technology does backlash.

The HTC One M8 charges rapidly thanks to its support of Qualcomm's Quick Accuse standard. Expect a full accuse time under ii hours from a 10W charger, although note that the charger included in the box outputs just one.5A (or 7.5W). It might be worth investing in a more powerful charger to get the quickest charge fourth dimension out of the Ane M8.
