Seeing all the battery posts here makes me jealous. Personally, my battery life is total crap. I am a heavy phone user and I want speed. With LTE always on and auto brightness at 50%, battery drains like no tomorrow. I am lucky to even get 6 hours. Even standby time sucks. Leaving the phone on table for an hour will drain 5% without even doing anything on it. I wish HTC made removable battery so I can get one of those extended batteries to keep me going all day :(

However, I know it is the LTE. I wanted to use my iPhone 5S the other day so I removed the SIM from my M8 and used my 5S for whole day. The whole day M8 was connected to WiFi and it only lost 10% entire day.

2 days on battery with 6 hours screen on time?! Are you kidding me HTC?

I'm running the fully stock 4.4.4 ROM (3.28.401.7), and now I don't have a single reason to flash a custom rom, or a kernel!

I had literally only one phrase to say...

WTF ?
[One (M8) General] VeRychard:
My M8 has 2 - 2.5 days depending on usage.

I strongly recommend using Tasker to automate your phone and power usage. For instance my phone doesn't connect to the mobile internet but every hour for 2 minutes when it syncs all my emails, etc, then goes offline again. However if I open an app I set previously (music, email w/e) it turns on wifi, if doesn't find connectivity, then goes to mobile net. On exit, turns it off.

Also with GPS, only enable when opening Google Maps.

Battery saving under 45%, extreme battery saving under 15%.

It's not that far fetched. I think signal strength while on data has a big part to play obviously and screen brightness. Obviously power saver will help... Tho I don't use it.

[One (M8) General] th3:

Unfortunately, both of those apps require rooting for them to have any functionality. I was trying to hold off doing that for the next two months because I recently got a HTC One replacement and their warranties are good for 90 days only with them. Wanted to make sure this device was in perfect shape before I started tinkering with it.
[One (M8) General] :
You're right about the apps and root. But unfortunately finding you're culprit will be near impossible then.

All you can try is temporarily uninstalling any apps you suspect could be causing issues. Process of elimination.

Not much else you can do. Start with apps that show as running or cached.

im getting between 4-5.30 hrs of SOT on an average with medium to heavy use. This is with location services turned on all the time, and some gaming, whatsapp, browsing, facebook, youtube, music, etc. I am very impressed with the battery life on this baby since its an upgrade over the htc one x :D
[One (M8) General] Jamal Ahmed:
I have the M8 since end of June, but I never pulled it's battery till the end. Today I decided to let it run till it ends. 5 hours screen on time, and 12 hours since unplugged.

I use a lot of Google+ and reddit sync, which obviously are constantly downloading images and so, so I'm sure others would have better battery life than my rough usage. But still, I'm deeply impressed, especially after coming from Note 3, I thought it would have a bad battery life considering the smaller battery size.
[One (M8) General] clusterchuck:
Still struggling to get 4 hours after shutting off a few things but that's good enough. I'm done obsessing over it.
[One (M8) General] KarimSalloum:
lol, exactly! Sometimes those battery life threads make it seem like people don't almost always have a power outlet nearby :) I get that sometimes you need autonomy, which the M8 does just fine, but overall, is it really that hard to plug in your phone for 30 minutes when you get home from work? makes all the difference in the world :good:
[One (M8) General] walle4893:
True.. Now I don't even bother to go to BetterBatteryStats or GSam to double check whether I have wakelocks (unless it is a massive one) and how many SoT I've had. Just enjoy the phone the more you notice the battery drains less juice you think it'd have. I guess we all don't buy it just to see how long can it last

Hello. My m8 started draining fast. It takes around 8% every hour without using my phone at power save mode. It keeps draining even at extreme save mode. Didn't have such problem with 4.4.3 android.

[One (M8) General] Droff:
As far as I know, you won't get weather updates on the lockscreen, might have other issues like htc notifications (missed calls, texts, appointments etc) not updating on the lockscreen.

I got rid of this wake lock by changing weather icons to my company logo and setting HTC weather updates to once a day. I use different weather widget on the homescreen.

If you use blinkfeed and htc weather widget, I suggest to leave htc service pack alone.

And again... That's only a few hours of stats. Charging to 100 and draining to about 10 or 15 percent is the best way to see what's happening. Are you rooted? Need root and gsam root companion installed to see those stats.

If you're not rooted, then it gets tricky.

Have posted gsam screen shots? Might find the issue.

If you're rooted, you need gsam root companion also... Then you can view the app wakelocks. Most issues are found there.

Signal strength, setup and usage are huge factors also. It's not always an actual issue... Sometimes it's just those things.

So I've had some really good battery life. Running ARHD 21.0 on latest fw.

Get roughly 3.5-5.5h SOT over 18-24h on 3G.

About 5-7h SOT over 24h on WiFi.

Last night I was on 59%, so before I went to sleep I turned airplane mode on. This morning (8 hours later) it was on 51%.

Looking at gsam and stuff it would appear the device wasn't even active (in deep sleep). Is this normal drainage? I hear people get about 1% idle drain with data/WiFi on but on airplane maybe 0.2% per hour?

Thanks.
[One (M8) General] :
I get about 0.4 percent drain per hour on WiFi.
[One (M8) General] Nokiacrazi:
Tomorrow morning I'll post some screenshots of my stuff. Perhaps you can help my idle drain?
[One (M8) General] :
You'll need gsam and gsam root companion. (Need root. With no root, we can't see wakelocks, so no battery screens will be helpful really)

Reboot before bed to reset gsam. Or reset stats in the app. Then do screens as soon as you wake up. Specifically the main screen, and in apps.. Times waking device and time held awake. Those are the real important 2.

Also though... If it's on data, not WiFi, with a low signal.... That can make your battery drain quick. Location services on won't help any either.

Good luck!

Run your battery down to about 10 or 14 percent left, with no reboots (gsam would reset) and let's see again.

Maybe include kernel wakelocks, times waking device and held awake time screens to the 2 you posted.

But really, your on pace for about 5 to 6 hours screen time.... I doubt you have an issue. It's likely your setup. Services you run and whatnot.

See post 2 in the battery thread in my signature for tips. ?
[One (M8) General] scorror:
Yeah, I followed the tips in post 2. Initially before the update, I get 7-8 hours dot, posted that here before. Not rooted. Just surprised by the spike in Kernel (android os) and Android System both used to be under 9%.
[One (M8) General] :
It's almost always location services fault . Turn it off and see the difference. Or at the least, set it to device only.

If that doesn't do it... It's hard to see if there's an issue unrooted, since you can't view app wakelocks.

[One (M8) General] scorror:
The Kernel and Android System are still high.
[One (M8) General] :
Are you rooted? You have near 3 hours of held awake time. That's fairly high. But you need root, and Gsam root companion to see held awake time and times waking device.

With location off, held awake time shouldn't be so high. Is Google now on? That will add to it. Are you running many social apps or multiple email accounts? That'll all take a toll.

Your battery stats aren't that bad. Average I'd say. But seeing the app wakelocks would help. Kernel wakelocks too which Gsam should show you, root or not.
[One (M8) General] spacemanvt:
Opo and the m8 share the same CPU and basically same screen (except opo screen is larger) so my assumption is battery life is more dependent on size... Hmmm

I can upload my 3C Process monitor logs might help shed some light although... i've tried optimizing the heck outta my phones processes and battery as well as applications running so... i cant say for sure what exactly is causing the extreme power drain. Sprints auto connection optimizer is suspect as the wi-fi keeps powering on thanks to the gps feature being enabled, it auto powers on the wifi if a known wifi is nearby regardless of wifi is disabled and in advanced menu the wireless is disabled for auto scan enabled. (I've not fully tried disabling it as of yet) as it helps alot with my 4g LTE acquisitions.
