Well that sir is amazing probably best I have seen. Do you use any social media apps? I feel like that's what kills my battery I even have Facebook greenified but I get a weird wakelock all the time that is audiomix but whatever my phone lasts the day at least and that's all that matters here's my stats for today

^That's very bad battery life.. Very bad.

But, hard to know why without looking at your app usage AND without you testing on stock first.

My phone is completely stock, unrooted. I disabled all my social media apps for that very reason, battery drain. I made speed dials in dolphin browser to social media sites so I can just logon through the browser. I only have my Gmail synced, notice how low my held awake time is. You should definitely be getting better battery life than you are currently getting.

My M8 Battery Life

There's something wrong with my battery life of late - something's keeping my M8 awake and I can't work out what it is.

I recently flashed Viper but went back to stock shortly after thinking it was that but I'm back on stock with the latest FW and am still seeing my battery seep away quickly over the course of about 11 hours.

I've turned off Google location and turn off WiFi at work. I don't want to start turning off everything on my phone as that's not what it's designed for i.e. social media and emails etc (although I only have emails syncing every hour whilst off WiFi).

I've attached my power graphs and GSam screens, can anyone advise further? It looks like google is the culprit when I've had a look under developer tools, it's asking for a location every 5 minutes or so but I'm sure I've turned everything off!

I'd love to get a day and a half out of the battery, I don't really use it that much and have the screen timeout and brightness on the lowest setting where possible as I know that's the main sucker of juice.

Thanks everyone!

Here's my medium usage battery stats mostly comprising of using the chrome browser for facebook, some news reading, listening to 1h30m of music and other apps.

It may be your signal draining you. No app will show you that... It just happens silently. Turn off data for 4 hours and compare. You'll still get calls and texts... But that's it. ?
[One (M8) General] eternal_inertia:
Thanks for your reply

I just don't like the look of the Awake graph when compared to the Screen On graph, it appears to not have time to get into deep sleep and I can't see anything obvious running.

Also, the Held Awake time in GSam is unacceptable IMO when my phone isn't giving me any notifications or any (known) apps are open and running.

I've uninstalled Life360 (geo location app) which I think might have been requesting location a bit too often to see if that's it but I still think there's a problem in the Google services somewhere keeping the phone awake.
[One (M8) General] :
Any app that uses location heavily, will take a toll on the battery.

Still have a feeling is your signal. Disabling data for a while will let you know if that's true.
[One (M8) General] th3:
Yea your awake times, total run time with very little screen on time are very poor. Others with similar usage are getting 2x runtime and 3x SOT. But your phone is over 3hr awake out of 4... So it's not sleeping at all.

Do you have power saver enabled?

Something linked with downloads, updates, notifications or media/videos/audio is keeping it awake IMHO. I've noticed that when I play YouTube for many hours, my app usage also has kernel right at the top.

I think HTC Check In service is the culprit. Try Force stopping that from the apps.
[One (M8) General] eternal_inertia:
I've turned off Life360 and it seems to have given it a bit of a boost but there's still something holding it awake. You're right my awake time is terrible.

I couldn't find an option to stop this in apps or in developer settings, do you know how?

I really begrudge having to disable services when I've only recently reflashed stock, it should work perfectly as if right out of the box!
[One (M8) General] th3:
Out of the box - you are right. These days, most mass manufactured products don't come truly 'optimized' for best overall experience.

They usually come optimized for ease of use and speed of operation, which tends to negatively effect other useful parameters.

Turn off automatic checking of OTA services and auto backing up to HTC servers - in your settings.

I've factory reset my phone and turned off most app's auto sync settings and denied all the google apps access to location until they're needed. I suspect one of the downloaded apps is to blame so will install them one by one to see if I can find the culprit.

The annoying thing is I've lost all my contacts - they're on my restore file in HTC sync manager but stupidly you can't choose to only restore the contacts. I don't want to restore the whole backup because I'm sure something in there is what's causing my battery problems.

Luckily all my music and photos are on my SD card which is un-wiped.

Does anyone know how to just restore contacts from a restore file in HTC sync manager?
[One (M8) General] :
Why not keep your contacts synced with Google? I've done that for years and never needed to worry about them again.

Dunno about that frankly.

I've always backed my contacts, call logs, bookmarks and SMS without doing anything (apps like SMS backup and restore come handy).

[One (M8) General] :
Add a contact , it should have an option to choose where to save it... Pick google, and it should always default to that.

I know that doesn't help you now... But for future reference. Saving to apps, or even Sims in not near as reliable.

My contacts just automatically show up when I set up a phone.... After many devices and 100's of Rom flashes. :)
[One (M8) General] racingmatt1:
Does anyone leave the 3g/lte antenna on all the time with WiFi on ? If not does anyone have any suggestions so the 3g/lte antenna turns on when the screen is unlocked,turns on periodically for auto-sync contacts,and turns off the radio when WiFi is connected?
[One (M8) General] :
If WiFi is on Data is automatically off. ;)

Radio is always on for texts and calls... Unless you're in airplane mode.
[One (M8) General] racingmatt1:
I thought the connection would still be technically on even though I'm connected to a WiFi network and draining my battery even more
[One (M8) General] :
Nope. It's off. ?
[One (M8) General] racingmatt1:
How would you/me know if it is truly off.
[One (M8) General] :
Just check your data usage. Right when WiFi is on.... Then again after a bit.

But if it makes you feel better, just toggle data of when you turn on WiFi. ;)
[One (M8) General] racingmatt1:
So if I have data/WiFi on simultaneously I won't notice a bigger strain/drain on the battery?
[One (M8) General] :
Simple. Go 2 full charges with just turning WiFi on when you can. Don't touch data. Then 2 days where you toggle on WiFi, and off data.

Compare. ?

But no, you won't. I've had tops in battery life on every device I've owned... And I've never toggled data off. (unless I am on data, not WiFi, and in a very poor signal area for awhile... That's a battery killer)

Is it just me or the power saver option doesn't do a lot for me. My phone is already silenced because of my Pebble. I don't like vibrations and turn them off. I don't notice any significant differences. Maybe on the extreme battery saver but not the regular one.

Update

So, yesterday I reset my phone to factory settings and when I was setting it up with google etc. I disabled auto syncing for almost everything and didn't install any of my own apps (I let Play update the internal apps to their latest versions but that's about it).

Seems to be a marked improvement today, see attached screenshots. I've used it normally (if not had the screen on a tad longer as I've been checking the settings regularly) and I'm still on 70% after nearly 7 hours. This time yesterday I was probably on about <50%. There must have been an app I had that was causing excessive battery hogging - or maybe my sync settings were wrong.

I've got google apps denied access to location, location set to battery saving, mail sync set to manual and all social media on manual. The only thing that should be able to push is my messaging apps like Whatsapp etc.

The held awake time is still bothering me and it looks like the services that are still causing an issue are DotMatrix (which I'm assuming has something to do with the Dot case - which I don't have so any ideas on how to remove this would be appreciated) and HTCCheckinService (which is still running 100%).

Overall though, I'm pleased with the changes I've made so far. I'd still love to get the awake time to something similar to the other posts in this thread so I'm open to further suggestions :)
[One (M8) General] Caspid:
I get around 17-20 hours.

Wish there were a way to toggle the cell, rather than turning on airplane mode then re-turning on wifi.
[One (M8) General] eternal_inertia:
According to GSam my average is around 15 hours which I'd be happy with. At the current rate I should be able to finish work and get home without having to charge it in the car, unlike a few days ago :victory:

Now I just need to work out which apps to reinstall and which I should steer clear of.

Also, BTW, I force stopped HTCCheckin and DotMatrix so will see if that makes a difference. I assume that if I reboot my device they'll reappear though.
[One (M8) General] Karlibri:
According to GSAM my average is 11h35, which is OK for me.

K... Had good Battey life before unlocking and rooting... But now that I've done those and debloated quite a bit and greenfied...
[One (M8) General] eternal_inertia:
That's amazing - I love that your held awake time is only an hour out of over a day. I would love to get anywhere near that.

As I thought, the killed services only restarted themselves shortly after I killed them. Hence why my held awake has gone down compared to yesterday but not hugely.

This is my latest GSam screenshot after 12 hours which is brilliant compared to yesterday but I can't help wondering why my battery stats are that much worse than these with a full day on battery...
[One (M8) General] th3:
Active time and screen on time are crucial indicators of activity power draw folks.

Standby time for sleeping power draw.

Looking at the phone variances, it would seem the average expected numbers under moderate settings and usage (with the power saver on and WiFi) are:

8-10hr active

6.5-8.5hr screen on time

That's without UV, UC or disabling auto updates, syncs, notifications and what not.

That's interesting. I've just googled media server and M8 and someone said it could be searching my media and getting stuck. I have 1000s of photos and music on my SD card that has been taken out and put back in several times whilst I've been rooting and returning my device to stock. Could it have corrupted somehow?

Also how do you know that it's the media server?

I might try formatting and then putting it all back on unless you have any other ideas?

Mine has been great! Lasts all day for me. And it charges super fast, heard it has a boosting mode to charge it quickly to 80% and the remaining 20% is a slower charge.

Just recently I've enabled Power Saving Mode and only reduced the CPU Power, everything else is normal, and this thing is lasting me EASILY a day and a half. Could possibly be two, but I haven't pushed it cause I need my phone and don't want to be anywhere where I won't be able to charge it.

NV release4 sense 6 Rom. Elemental kernel stock thermal throttling, on-demand, cpu power save function enabled. Screen on time was about 1 hr 15 mins. I would say 16 hrs and 79% left is excellent. Especially coming from a G2 with that huge 3000mha batt!

Interesting. I had an oppo find 7a before my m8 (traded for an m8and a nex5). The Oppo had a cool feature like that where it charged super fast, but you have to use it's 4.5 amp wall charger. Normal chargers and USB we're still standard 2 amp max. It truly did 0 to 75% in 30 mins! And on a 2800mha batt too.
[One (M8) General] leo9891:
I wasn't aware of this "feature" till I stumbled upon a post like two weeks ago. It also said to enable this "feature" in the power settings, but I don't see an option for it, thought it might only be seeable on certain carrier versions.

I never doubted it because it really does charge insanely fast and does not deplete rapidly. Just thought it was a great battery and charger ?

Best phone I've had since my Galaxy SII.

Edit: So I've done some research and the feature is called Quick Charge 1.0. The HTC one is Quick Charge 2.0 compatible, but it's not enabled until a future update. And to take full advantage of QC 2.0, you need a QC 2.0 charger. Here's a link I found, it's about the Extreme Power Saving Mode but also talks about the Quick Charge feature. Check it out.

Well I have no idea what I've done but my battery performance over the past 2 days has been amazing and I don't think I've done anything!

I'm guessing that whatever was holding it awake has finished what it was doing and the phone has got into a normal rhythm

I do hope it stays this way. This is even better than before I messed about with custom ROMs and then went back to stock. I used to be able to watch the percentage go down like 1% per minute of screen on time.

Hopefully this will last! Thanks for all your suggestions I'm sure they've helped.

Attached are my 2nd charge results. I will note, please add about 20 minutes of screen on time to that number. I rebooted my phone at 92% and lost the stats which were about 20 minutes.

Overall, under moderate/heavy use, this is a 7+ hour screen on time phone. That's amazing to me... this definitely blows away the M7. Standby is also great, been off the charger for 3.5 hours, only used the phone for about 10 minutes, currently at 97%.

This had 20 mins of wifi all other time was 3g (no 4g here yet) Google now / locations ON. auto brightness on with max 70-75%. 4 mins calls. Roughly 30 - 40 mins of music via Deezer. the rest was You tube FB Twitter etc and browsing web, probably about 40 - 50 msgs sent via whats app / Viber.

7 hours of on screen time is better than any phone out there. It must have to do with the new chip and the ability to keep things from running in the background all the time. I get crazy stand by time and have no power savings on at all.
