Ok, my incling was right - it's media/SD card related. I mean, this standby issue.

Look at this (+95% I was in standby):

And when I had the wakelocks:

Time to unmount SD [emoji20]

I've heard this media server drain is only caused by corrupt/broken or too many scattered media files on your card which the OS keeps scanning for and accessing. I've heard a cheap quick test is to place a .nomedia file in each media directory, and that should fix it.

The battery life on M8 is great, but...

http://www.eprice.com.tw/mobile/talk/124/4899675/1/rv/sony-xperia-z2-review/

When I read this article, I think it's true. HTC tries to make the CPU frequency lower than normal (a dedicated CPU governor?) in order to save the battery life. Normally it will result in a significantly lower benchmark result and make some (or many) disappointed, so HTC decided to use the unable-to-turn-off benchmark "optimization" to get equal or even much higher benchmark scores. The difference of Antutu and Antutu X is the evidence (38k vs 27k)

Anyway, the difference is only in loading speed (game loading, app loading,..), not the smoothness and normally negligible but a little bit feeling of deception here.

[One (M8) General] whmcal:
Like many, I was sceptical after hearing HTC were only adding 300mah to upgrade the battery. Afterall, the M7's battery was so poor. Upon buying the M8, what hit me was that it's battery life rivalled my old Note 2's.

My M7 battery would barely last a working day with heavy use. The M8, seems to be able to last well over a full day on heavy use...approaching 2 days. Took it out of the box and it was at 73%. One day 14 hrs later, it's at 11%.

With a battery that's this good, improved processor, improved BlinkFeed, gestures and improved build...I couldn't give two hoots about the camera being 4mp!

Hmm can't seem to find any screen shots of usage purely on LTE.. I think that's more useful to gauge battery life..?

And a low CPU governor also:p HTC forces the CPU running slower (except in benchmark,lol).

But anyway I think the mobile CPU now is overly strong and overrated. I would rather choose better battery all the time with an acceptable smoothness. I use battery saving mode on my Note 3 (limiting CPU speed) all the time and feel no problem with its speed.

The more apps accessing data on their own, or during use.... The more your signal strength comes into play. Weaker signal, big drain with lots of apps accessing data.

HTC One M8, EU, stock Sense 6, 5.0.1., no root

Averages from the hard reset I did (Feb 1st) prior this test can be seen below. Those are my normal daily readings I agree with. Usually Play services eat a whole lot but I reset the data and caches of Google apps.

Here are my findings:

The phone lasted longer than in June when I conducted the same test on KitKat when the phone was brand new. Back then I got 11 hours.

I think I should start using the "who gives a damn about the battery and just use the phone normally" approach from now on.

So I'll repeat your test and see... Maybe you're one of the few without the drain.

It's made absolutely no difference to mine. In fact, Google sync doesn't won't anymore :(

[One (M8) General] high_voltage:
Good test, but still few thing to note if I may?

1st: brand new battery tends to have less than optimal capacity. Li-pol batteries tends to get max capacity around 1-1 and a half mouth after started use.

2nd: your test is not real life condition, but controlled one with predefined using patter with may avoid the "draining scenario". After all if it wasn't under certain conditions, htc would have been noticed it before launching... or they did, but didn't have time to fix it so they can be close to their promise about the 90 days.

3rd: Not all got battery drain and certainly is not a placebo as few very experienced users reported it. For me the drain is under certain apps/usage patter/conditions and some replicate it, some not.

Interesting find from me: Atleast for the last version of facebook application I noticed devastating batt life bug: If you switch from recent tab or press home screen button the cpu usage of FB locks to 4 cores, around 50% use and 1.9-2.3GHz each. :eek: true story! If I exit with backarrow or/and swipe it off recent tab it settle to one core 300MHz with little fluctuation as it should. This is biggy and I noticed it after seeing my battery dropping like crazy with screen off/idle usage. There you have it... one/two more apps that misbehave like that under 5.0.1 and voala = noticeably worse battery life. Because I can give you second example: twitch app if you press home while stream was on it will continue draining the battery while if you exit the stream even if you press home - no problem. On kitkat it wasn't like that. Maybe it's related to project volta_will_f*c*_you_up? Maybe something else and God knows how many apps got misbehavior to some degree...

I am not saying I am right and even I am not sure for myself yet + I am not rooted with limits vastly my ability to trace usage/processes/etc, just sharing my findings so far.

P.S. Yep, kitkat got way better battery life vs lollipop, atleast for me + I did hard reset... two times.

We're talking about the stock drain in standby rather than app drain.

It's definitely there for anyone savvy enough to trace it.

Easy look at GSAM tells me, as the temp and current consumption is reported 310-450mA now, while the phone should be resting.

KitKat had 170-210mA on the same phone.

Non Google Apps may have their own settings.

Of course, with a weak signal on data... Anything that syncs or contacts the outside world will destroy your battery quick.

But if you just moved to lollipop, many here and on other devices have seen everything go back to normal after a factory reset. Of course that means all your apps and data would be wiped. But it has worked for many.

Someone without a base yardstick wouldn't even realize this problem exists. But my yardstick is confirmed since a year, in the form of KitKat.

When you have YouTube, Gallery, Internet, Calls and Whatsapp consistent usage... Android OS, Kernel and Media Server cannot be draining most of your battery. Especially not the 45-85% I'm getting.

It shows in the total runtime too, which is more or less halved.
