HTC One (M8) battery life test: excellent endurance

posted by Daniel P. / Mar 25, 2014, 11:49 AM

The new HTC One (M8) has a sealed 2600 mAh battery that clocks excellent endurance

Believe it or not, the new HTC One (M8), with its 2600 mAh battery, tops the mighty LG G2 marathon runner, and its 3000 mAh unit, in our battery test. As you can see below, the One (M8) lasted 7 hours and 12 minutes of screen-on time in our grueling test load, while the G2 scored 6 hours and 48 minutes.

In fact, crossing the 7-hour mark on our battery test typically signifies entering the phablet endurance realm, as those big-screen handsets usually have place inside for much larger than the average batteries. We can only say kudos to HTC for this spectacular achievement, which is bringing us a 5-inch handset that is only outlasted by giant phablets like the HTC One max, or the Oppo N1. The HTC One (M8) also flaunts an extreme power-saving mode, that lets it last about 30 hours on standby, even with 10% battery capacity left.

Its 2600 mAh unit is of the lithium-polymer variety, and is only 13% larger than the 2300 mAh juicer of last year's HTC One, yet brings in a whopping improvement in battery life, as the old One scores 5 hours and 45 minutes on our test. Needless to say, we can't wait to pit the HTC One (M8) against the other two spring chickens - Samsung's Galaxy S5 and the Sony Xperia Z2 - as those two also promise enhanced endurance, and dedicated power saving modes.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

name	hours Higher is better

HTC One (M8)	7h 12 min (Good)
LG G2	6h 48 min (Average)
LG G Pro 2	6h 48 min (Average)
Sony Xperia Z1	4h 43 min (Poor)
HTC One	5h 45 min (Average)

...Because it's Li-Po not Li-ion which is something people continue to overlook. That's like when everyone judged the Moto X over it's 2200 mAh battery but were surprised to see it outlasted the other flag ships? Why? Because it had a Li-Po batter with great software and hardware optimization. It just makes me a little sad when people try to find security in the numbers rather than the results.

Does that mean that this battery is any less amazing? I'm confused by what you are getting at.

Destroyed by what? by Samsung's ugly design & cheap plastic? Or power hungry battery? Or by laggy TouchWiz UI?

How are you so confident the S5 battery will last longer? ONE 2014 vs S4 (same size battery); ONE 2014 beats it by 2:13. S4 vs ONE 2013 (smaller battery by 2300mah), ONE 2013 beats it by :46. The ONEs are more efficient than the Galaxy Ss so the battery doesn't need to be as big.

So if I place an S5 next to an HTC ONE some how some way the HTC ONE will shatter? It will melt? It will explode? Outside of horrible grammatical expression on how you prefer the S5 features over the ONE features how will it be destroyed. Just because it sells more doesn't make it better. There are more Honda Accords being sold than the Audi S4s. That doesn't mean one car will literally destroy the other if they park next to each other. But I bet the Audi and HTC will get more looks.

Wow that was really quick battery life test, I mean, the phone was just announced couple hours ago. Unless PA already had...oh wait. I gotcha.

Against the S5? 1520? Z2?

Well S5 hasn't been released yet, the 1520 isn't even in this level....it scored like a trillion hours.....why should it be considered...it's on another level completely, in fact in another, realm....no dimension!!!!...no Flux Vortex....no...Event Horizon... Another thing too....people are seriously overlooking the type of batter. It is not a typical li-ion battery....this is Lithium Polymer with long bonding chains that discharge electrons at a constant but slow rate, due to the density (if I'm not mistaken but I feel like I've learned it terribly wrong LOL)...2600 mAh for Lithium Polymer is like 3500 mAh in li-ion... So just imagine if the One Max gets a 3500 mAh li-po battery...It'll be hella expensive for production but we'll probably see 11 hours of custom script time, which might translate to 56-72 hours of mixed to light usage...but that's just dreaming. HTC, really let me down with the camera and I was the main fanboy rooting for them. LOL. Well, better luck next year, I hope.

We all know why cause GsmArena gave it the first 100 hours endurance device to gain this long stamina.

It's not entirely impossible to top 7 hour screen time on other devices. It's not easy, but possible. Longest I've seen on an S4 was over 7 hours in the XDA Developer forum.

Those are all anecdotal and don't really count for anything in terms of concrete data. Anybody can sit next to their wifi router, disable all forms of syncing, with the lowest brightness levels to exaggerate their battery life.

Not entirely true, but I see where your getting at @erikiksaz. It depends mostly on optimizations and the type of Nm chipset also the screen tech. If all these are passed interms of lower power consumption, then like HTC one m8, you get over the limit of screen on time.

Now where are those who were complaing about the 2600 mah battery.This is not the only test to prove great battery life as gsm arena's battery life test put the new one on par with note 3 with 71 hours of endurance rating.HTC nailed this!
