Well, I've gunned it down. There's not just one problem here, it's multiple.

Problem 1: SD Card, broken files?? Format and putting them back on dropped the drain a little.

Problem 2: Google Now (Search). Keeping audio_on user wakelocks through mediaserver UID 1013. This was so hard to find, just trial and error. Instantly noticed drain going from approx. 370mA to 230mA on removal (consistent).

In regular low usage, mediaserver was like 40-60% of my power usage with no media usage. That triggered the alarm bells. The problem is, Android doesn't provide specific info as to the process using UID 1013. You're left guessing. I don't think it's fully resolved yet.

Problem 3: Standby drain. Still testing the cause of that... Whilst the phone should be sleeping.

Greenify has helped in this massively. In helping the phone get to sleep.

I had a lot of audio on time on sense based roms too. Now on a CM based Lollipop rom, it's gone. I don't get it either.

But as far as it killing your battery.... You my friend have nearly the best times in this thread on Lollipop. I'd let it go. Must be a sense/Lollipop thing. And battery life may not be quite as good as Kitkat.... But it's new. Some updates down the road may improve things. ?

I'd enjoy your phone! I ran an extremely lean and debloated system always, and on sense I had all that audio on too. But I'm not sure it actually hurt anything. My Lollipop times are about the same as my Kitkat times personally. ?

In fact, on Sense with hours of audio on... My times were still about the same as they are on CM based rom now, with no apparent audio on time. (see screen shot)

Most would kill for your times. Lol ?

I understand what you're saying, but this is with low usage.

Same for me - I was used to have 7:30h screen on(medium-heavy usage with lots of twitch, youtube, facebook, chrome, messenger, viber, little gaming) and whole day battery life. Now I am struggling with light-medium use to get 6:00-6:20 screen on time. If I pull the past usage I get around 5:30h screen on time and that after resets, less apps downloaded, more battery friendly settings and sh*t... really disappointing as battery life is crucial to me. This showed us good what happens when you are smaller company and make big promises as I didn't heard worse battery life on other lollipop releases and companys like sony/samsung are releasing soon while lg g3 didn't got any complains about battery life on lollipop. Grrrrrrr :( /rant
[One (M8) General] Badelhas:
I ask once again: whoever uses 4G only during the day and is a medium / heavy user with auto brightness full slider, how much SOT do you get?

Seems to me that the guys who get 6 hours SOT use manly wifi... Makes all the difference
[One (M8) General] :
Screen being bright is a huge killer. So is auto brightness period. ?

I use "display brightness" from the play store to control it manually and keep it as dim as is comfortable.

If I use auto brightness, I can kiss a good hour of screen time goodbye.

Just my 2 cents.

(and I average 8 hours SOT... With my type of usage and setup... On data or WiFi.)
[One (M8) General] undyingdest:
The most I have been able to achieve from my M8 without powersaver / any 'tricks' for batter life besides a stock elite kernel flash and the Adrenaline rom was a little over 2 days (mixed use between small amounts of gaming and decent amount of music time) ..

You get 3 or 4 hours, tops. So don't try to say that you somehow got a m8 with a higher capacity battery than ours cause I don't buy it and your last screenshots show exactly that.

And for the record: I did get 7:30h screen on with heavy usage and 20h + half of the day on mobile data, autobrightness auto and full slider, without any power saving option... but on kitkat. Now I can't , but I am not rooted so maybe few can, depending on usage, kernel, setup, etc. Mobile data is variable too as you can use it for viber or for youtube hd with will obviously drain battery a lot faster. Just stop that argue and be sure that most likely your battery is same as mine, as his and as everyone. Just usage, settings, signal strength, etc, etc, etc.

That's what he just doesn't get.

How wrong he is. His approach to this matter has been completely wrong and bullish.

I am not getting good battery life with Sprint HTC M8 H/K edition. I am using 2nd phone as HTC replaced my phone after 7 months of use and I received brand new phone from Marketing department few days back, as they couldn't serve their promise.

I can see many people getting good battery life and few say it was better in Kitkat. In my experience I never had such great battery life and with normal usage it is in red by 7PM (i unplug at 6AM and the usage is for basic whatsapp, facebook, calls, etc). I had my previous device rooted and this phone is at factory setting.

Can someone confirm, if they are getting jaw dropping battery experience on CDMA phones like Sprint? If so, did you tweak anything?

Or if its not CDMA global phone I have reasons to believe Harman Kardon edition has some defects in default tuning.. some advice is really helpful apart from rooting (I was a great fan of rooting and making tweaks from the time of HTC Desire HD and learnt over a period of time, phone can't be perfect if it's rooted - there will be some bug, or something is lacking. If I had time I'd have definitely liked playing around with rooting).
[One (M8) General] th3:
And here is when that battery died.

Note: I have a poor 4G/3G signal.

5h38m SOT in 76% battery

Slider full right, Autobrightness

In and out of home for hours each time

So, 99% battery is: 7hr 24m SOT

From the link

Uploader's notes: To figure out the right version of Google Play Services for your Android device, go to Settings -> Apps -> Google Play services, and look at the last 3 numbers in the parentheses. You'll see something like -XYY where X is 0 for pre-Lollipop and both 4 and 7 for Lollipop+, and YY is a specific variant id. -738 means you need the APK that has -738, etc.

Note: It seems that -7xx builds became -4xx with Google Play Services 6.5. If you were on -7xx before, you should now install -4xx.

You're exaggerating it's gains. And that's what quantifying it would show you.

Dimmer screen and low clock assumes I'm usually high on clock and high on brightness. Which is only the case if you're out in the Sun playing a game/watching a good IQ vid for all that time.

With Power Saver and Without, at the very start of this thread, some including me tested it out. There wasn't much difference (less than 40mins SOT).

Battery life solely depends on your set-up and usage. For me, I tend to chat with friends and team mates a lot on whatsapp but I don't game nor browse the internet and thus battery life for me is quite good. I can easily obtain 30hrs of standby and 6hrs+ of SOT :p

What could i do more ?

Stock Non rooted
[One (M8) General] :
First, why the naughty language?? :confused:

Second, your signal strength is causing the wakelock. Apps trying to access Data and are having trouble and it will cause the wakelocks. The fact that your 4g drains you fast confirms this. 2g/3g is doing the same, only slower.

To prove this, put on Airplane mode awhile, or toggle data off completely, or get on wifi. Watch your standby drain greatly improve. And the wakelock should stop, or at least pause until you enable data again.

You've done all you can do, which is try 2g/3g....but obviously it's not enough. All those social apps and anything else that like to spam data will destroy your battery. Location Services on whill make it even worse. You can toggle data off when in weak signal. You'll still get texts and calls, but that's it. And toggle data on when you need it, off when you're done.

That's all you can do. Or use wifi.
