BIGGEST factor in battery life is your strength of coverage... both cellular and data.

All these freezing apps and **** is ok but if you still have average coverage you will have average battery life. Simply put.

Edit - Just look at this guy's screenshot a couple of posts above: http://img.tapatalk.com/d/14/06/20/urasu2yr.jpg

Look at his network signal... the darker the color the better/stronger the signal. Notice where he has a very strong signal his battery life lasts (flat) and when it goes to a weaker signal it drains more.

Battery life for me is amazing over what my M7 was, which was well over 12 hours of moderate use. i'm currently sitting at about 18+ hours of use on my M8 with moderate use. Im on wifi all day at work and even stream music quite a bit.

Impressed after two months.

If I didn't make so much phone calls, SoT would be 6-7 hrs.

Battery life has improved significantly since using wakelock terminator on those wake locks.

What's odd is the amount of times that Google Play Services seem to wake the device. Even over a long period of time, the amount of times seem crazy still.

Edit: Looking in HTC Power settings, it shows that all the wakeups have kept the device awake for only 3m 50s, using 2% of battery overall. Obviously nothing to worry about, but still interesting.
[One (M8) General] EternalAndroid:
How long until you're able to see results from blocking Google Play Services?
[One (M8) General] NJGSII:
Well I haven't blocked Google Play Services cause that's needed for a lot of the Google stuff on the phone. And since it's not causing any drainage whatsoever, I'm not worried about it.

Attached is what I have done via a post from reddit and it uses wakelock terminator.

Still would like to know why it's waking up the device like that even if it's for a spit second.

Can someone tell me the pros and cons of switching from the dalvik runtime to ART?
[One (M8) General] BadAzDB:
Pros:

Better battery life (theoretically)

Faster

Cons:

Not every app fully supports it

No Xposed

It's good if you're going for a stock look with minimal mods/features. The sense rom which offers the most customization with ART is INSERTCOIN. Other ROMS either won't work with it, or you'll have a stock look as I mentioned earlier if you enable it.

[One (M8) General] BadAzDB:
Yeah, since you're already not using xposed, I'd advise switching to ART. I've yet to come across any app not compatible with it. So there will be basically no cons for you since you're not rooted.

[One (M8) General] BrandonShea:
Battery saver on all the time (not extreme) LTE coverage is OK with 3/4 bars usually .I only get one in my room downstairs so thats a bummer.

Not sure what BBS is. I have location on all the time usually because I drive a lot and have no idea where im going half of the time.

Wifi on

BT off

Location on

Power saver on

Phone is apparently only one month old. Traded it for my G2 to some guy. In great physical shape, its the darker grey variant.

I'd take a picture of my Gsam battery monitor but it's not letting me sign into tapatalk on my M8 right now for some reason.
[One (M8) General] Sir-Fix-a-Lot:
BBS is Better Battery Stats, its useful for tracking down battery drain issues. The main things that will drain your battery is screen brightness and location being on. And obviously heavy use. I don't use Sense, but I have broken 2 days with 35% left. Use auto brightness and keep location off unless you need it, then switch it back off.

Here is Better Battery Stats, a great app:

[One (M8) General] Sir-Fix-a-Lot:
Well it would just depend on how many apps you have using it. If you're constantly navigating and such its gonna be a pretty big drain. The weather app also uses it, and so does Facebook.

[One (M8) General] koolfoolx:
Sorry to jump in the middle, but when you say GPS off do you mean switched off. Cause when I toggle it off in quick settings it just switches gps to power save mode. Would you recommend turning it off all the way or is power saver for the gps fine? I've tried everything to get better battery life but I'm not sure what I'm doing wrong. I've greenified apps, I've even switched from viper to cleanrom and I'm running the stock kernel that came with it. I tried running with and without power saver with the turn vibrations off, limit CPU usage, and lower screen brightness checked. I still don't get over 4hrs of sot. I have Kik installed and that has the most amount of wakeups. But is that a major battery drain? Does anyone else use Kik that can give their perspective on it? sorry the long post D:
[One (M8) General] exSD:
The biggest factor in battery life is your signal strength, period. Then it comes down to usage of data/cellular data like SMS. Then it comes down to location services... see the big on/off toggle under Settings -> Location? Toggle it to OFF. Location is off otherwise apps still use location services in power saver location mode. Then it comes down to nitty gritty wake locks.

People who are getting ridiculous SOT probably have superb, superb signal strength.

AT&T, stock room, dalvik (Nike Plus Running takes forever to load on ART, but I could live with that).

What screen shots of GSAM would you guys like to help me troubleshoot?

I know that it wont be anything like the Nokia but I'm hoping to get somewhere around what I got on my Xperia Z1

[One (M8) General] HtcOneJon:
Completely disagree with you there. The biggest factor in battery life is screen brightness. Every single person in the world knows that. Signal has never ever affected my battery life in any significant way. Whether i'm at work with almost no signal or at home with full bars, same battery life.

I also used to believe 2G made a big difference in battery over 3g/4g. With this phone im on 4g 1 bar or 0 99% of the time and get great battery life.

I would say I get 4-5 hours with brightness at 75% on 4g 1 bar or less, brightness at 1% gives ridiculous savings.

If I were you I'd do a factory reset and start all over again. Leave out as many apps as you can and slowly add them back to seen if you can catch whats killing your battery. Also, if you have multiple email accounts syncing, try cloud magic email app. This will allow you to turn off syncing all email accounts bar the cloud magic app.

I am running on Maximus HD 6.0.1 with the latest firmware and I am S-Off with the kernel bundled with the ROM. Yesterday, I charged my phone to 100% I watched some Utube and used the FB app for a bit and went straight to bed with 91% left. I tuned on the DND mode and left both data and wi-fi on. When I woke up the battery was @ 79-80% which is way worse than Maximus 5. I have also noticed that the battery is getting worse in general. I am using Gsam w/ the root companion and the Xposed module for KitKat BatteryStats. Any advise is welcomed.
