Head To Head Battery Comparison

[smitty543]

Has/Have there been head to head battery comparison(s) between similarly configured Galaxy S5 and HTC ONE M8. The one on reviews merely state experience with single models of individual mfgrs. It might be helpful (at least interesting) to have comparisons of similarly configured phones.

You'd need a lot more than that to make the comparison meaningful. Compare phone configurations (with some configurations, phone A may use less battery, with other configurations phone B may), different battery distributers (is Anker/Hyperion/OEM the better battery), etc. Just Phone A out of the box uses less battery than phone B out of the box doesn't mean anything to people who frequent forums like these. Most of us consider "out of the box" the point from which we make modifications to the ROMs, settings, apps, launchers, etc. My Note 3, same usage pattern (you can't guarantee exactly the same usage on two phones at the same time, let alone on a phone on different days) shows a MARKED difference in battery usage from ROM to ROM. Turn off all the radios and I can get over 4 days to 90% on some. Run with 2G on and I can barely get 10 hours on others. Another phone may have different sensitivity to radios being on, etc.

And the comparison won't show how the phones will run with YOUR usage pattern, only with the usage pattern of the person conducting the test. Your usage pattern may make the best phone in the comparison perform worse (battery-life-wise) than the worst one. We're not comparing apples to apples like that, we're saying that my grapefruit is larger than your grape. We know that, but so what? It's a meaningless comparison. You have to compare different batteries against different configurations that YOU'RE going to use against different patterns of YOUR usage - against different phones. And that would be a 4-dimensjional graph - that would show that some phones are better in some situations.

If you want great battery life, use an iPhone. They're better than Android in battery usage. (And a lawnmower uses a lot less gas than a truck.)

The mileage on battery will obviously vary with everyone. It depends on how it's used with apps, settings, location, etc. Still it's possible to measure/compare continuous run down time with talk, browsing, video as the following links did. GS5 did pretty well here and it won M8 by narrow margin.

Of course it doesn't mean you will always outlast anyone with M8. I think either phone is fine with battery and they are pretty much equal on that.

there have been a number of head to head comparisons using standard battery tests (looping video, phone calls, screen on time, etc). the s5 has come out on top, but not by a huge margin. not surprising considering the s5 has a 2800mah battery and the m8 a 2600mah battery.

the biggest advantage for the s5 in the battery dept is an obvious one, the replaceable battery. both phones have a low power saving mode that turns off nonessential features to extend what's left of your battery.
