Forgot to include the apps usage shot.

Im on the latest Kangakat rom and have Bluetooth on, WiFi on, NFC off, location off, disabled location for many apps including android system using the xposed AppOps (only left it on for settings, navigon and Google maps. I also have auto brightness on and adjusted some lux values with gravitybox to make it slightly darker. I use k9 mail (modified the apk to change the name to just 'Mail' and changed the awful icon) for email with full push syncing for 2 accounts.

I was able to squeeze out more battery by using greenify. Most of my user apps and system apps are greenified (including Facebook and google play services).

Is your setup similar to my setup in the post above?

Call me a noob but what does undervolting achieve? Positives and negatives?
[One (M8) General] onukomer:
My new stats.

HTC One_M8 cihazımdan Tapatalk 2 ile gönderildi
[One (M8) General] petiha1:
Positives. AFAIK it reduces the lowest frequency your phone can function on, therefore increasing battery life. (stand-by time, etc.)
[One (M8) General] AndroidInsanity:
Does it affect performance?
[One (M8) General] petiha1:
No. When you're using CPU intensive apps, the phone is going to function on higher clock speeds therefore it has no effect on performance. :)
[One (M8) General] Xdpker06:
I had average battery life, around 5 hrs/full charge, but I installed Wakelock Detector and Greenified the apps that kept waking up the phone e.g. facebook, maps, google search. Battery life improved dramatically to around 7 hrs/charge. Stock rom, rooted, s-offed, auto brightness.

Medium usage..facebook, instagram, foursquare, reddit, xda etc. 25% used 2 hrs screen time / 7 hrs of being on. Not bad
[One (M8) General] Hellscythe:
It doesn't change anything regarding CPU frequency. It just lowers the voltage required for each frequency step.

for example on stock settings, 200mhz requires 800mv, but you might be able to undervolt that to 750mv, meaning there is less power draw compared to stock.

The downside is that it will affect the stability of your phone (random reboots, freezing) more than prolonging your battery life.
[One (M8) General] PcFish:
Just got my phone from T-Mobile yesterday. Unplugged at full last night, woke up 11 hours 49%. Anyone else have this problem from T-mo? I suspect it's bloat, but don't want to root while that 14 day window to exchange is still open.
[One (M8) General] Xdpker06:
Yup, bloat and a lot of wakelocks. Facebook waked my phone up 400 times throughout the night. Download Greenify

Battery :{

My battery seems to be a little weak compared to the rest...

Please let me know what you guys think
[One (M8) General] daddioj:
so far atleast in my findings. nothing beats the battery life on the GPE edition. conversion. maybe 1.54 would be better optimized
[One (M8) General] AndroidInsanity:
True. I got amazing battery life on GPE. Shame it doesn't have the sense camera otherwise I would still be on GPE
[One (M8) General] daddioj:
the new google camera is really not bad plus is still has the edit modes. I take pics but am not a fanatic over it. I am over battery life though considering I had the G2 before this and the battery life was insane if they made a google edition I would prob still have it
[One (M8) General] jags_the1:
If it did not have effect in performance it would have been a stock feature. Just sayin.

I've have tried under volting for almost a year and it never brought anything impressive to make me keep undervolting my device. Maybe a mere 15 min more battery life. Screen/3g/lte are the biggest battery drainers, better to focus on saving from there then wasting time on undervolting
[One (M8) General] AndroidInsanity:
The issue with it is though, before Google brought the new Camera app, in gallery you could still edit it with HTC image editor (Ufocus, 3d dimensions ect) but ever since the latest update it's somehow broke it and you can't use HTC image editor now :(

Now there is just the stock android image editor.
[One (M8) General] BerndM14:
so I've been doing some light general use. Still watching some YouTube and Google + here and there. As you can see there are some shortage on the wifi usage 'cause I know for a fact that the wifi has been on the entire week. Also you'll notice the battery percentage isn't right either it went from 80 something % as I did reboot the device to get into stock recovery to make sure of something, this was as you can see over 2 days ago before then the phone was already on for more than a day since last charge and had more than 1 hour on screen time. SOT might not be a lot but still some good endurance. Going for 4 days with no charge and still in the 40s.
[One (M8) General] EtherealRemnant:
Okay the battery life on this thing is nothing short of phenomenal.

That's auto brightness and the screen on time was split between YouTube videos and Brave Frontier.

Considering that I don't use the power saver and that there was actually a reboot in there (hence why it only accounts for 71% of the total battery), to say that I'm impressed would be an extreme understatement. I have it overclocked to 2.45GHz and it is undervolted by 45mV (which is what the reboot was for - to install ElementalX) but still, my M7 wouldn't come anywhere NEAR that!

I'm on my third charge since I got the phone on the 21st. About to put it on the charger now. I had to put my M7 on the charger daily. Seriously mind blowing battery performance.

InsertCoin 2.3.3 w/ ElementalX .9
[One (M8) General] BerndM14:
Yeah I'm also seriously impressed and happy with this battery. To think I was considering not buying it exactly because of negative feedback about the battery. I'm glad I ended up buying it though, amazing battery life and more than suitable for me and how I use the phone daily.

Coming from a change out to a new battery once a day and charge twice a day SGS3 ( :( ) to charging once every 4 days+, yeah massive improvement. :D
[One (M8) General] EtherealRemnant:
Yeah I remember the S3... Damn thing couldn't hold a charge for anything. Even if it was sitting there doing nothing it just drained away. Had to charge it every night or it was dead by morning.

The M7 wasn't as bad as the S3 but the M8 is on par with my roommate's G Flex which is extremely impressive considering the difference in battery sizes (3400mAh for the T-Mobile G Flex vs 2600mAh for the M8). Any worries I had about battery life are completely gone - and the M8 doesn't overheat either, something the M7 did whenever I would play certain games (Brave Frontier is a perfect example).
[One (M8) General] malek777:
I'm on my second day with the m8 and so far I'm disappointed. Compared to the LG g2, another phone I have it's not even close but I'm going to give it more time.
[One (M8) General] otariq:
Do you guys know what this process is on better battery stats? I'm not running the power save mode. Today, the awake seems to correlate with screen on but a lot of times the the phone is awake when screen is off. So I'm just trying to figure out if it's a rogue app keeping the phone awake

[One (M8) General] dkreventon:
My battery life is amazing on my One, I can get 3 hours SOT with 50% battery life, but the problem is that standby time is very poor. I have only basic apps installed, just like on my previous note 3, s4, m7 but on the M8 I come home at 2pm and I sleep untill 8-9pm. When I wake up my battery drops to ~30%. There is nothing causing wakelocks or drains in battery usage or gsam, I just leave the wifi on.

The running services are gsam, google location, facebook + messenger, whatsapp and swiftkey. Sync is off, I don't use google now or even google search. I tried turning off motion launch gestures, no improvement.

Any ideas? Thanks.
[One (M8) General] Frankie1588:
I would set it for last full charge at first and them you can change it if you want to get more accurate results. Good night! Im very impressed with battery so far.
[One (M8) General] pacman82:
Could anybody confirm if you were to use a more powerful ac wall charger like an ipad charger, would the m8 charge faster with quick charge 2.0 enabled, or does it have to be a htc charger?
[One (M8) General] Bigal77:
I checked qualcomm website.....apparently the 2.0 charger is not out yet.......so that's why htc didn't include it. Should be out later so basically anything you use won't have the 2.0. Maybe if you use a 2.1 amp plug will help, but still won't be 2.0 quick charge yet. Make sense?
[One (M8) General] Traceamount:
I'm at 39% after 12 hrs 51m. This was after my initial full charge. Not sure of screen on time - but I was taking video, pics, playing with blinkfeed etc all day, haven't set it down for more than 5 minutes or so at a time :)

Thats with the power saving option turned on, wifi turned on 100% but not always connected (wasn't home all night), and GPS on for roughly first 2-3 hours.
[One (M8) General] pacman82:
Ya sound for clearing that up, was just wondering, I have the m7 and I'm thinking of getting the m8, only thing that pissed me off about the m7 was the long charge times!

Battery

Thats terrible, my M7 goes all day, normal business use, constant email push,

txts, web surfing etc and normal day for me is 15 hrs with anywhere from 25-40%

battery left. My phone has always had excellent battery life from day one.

I have BT in car running constantly, WIFI always on, and GPS ON constantly

with Device only option.

I was very skeptical of the 40% better battery than the M7, and I can see from numerous forums this

is just not true.

[One (M8) General] CandyAndy:
Thats not very good. Pretty similar as with M7, maybe slightly better. Battery and camera are the only things which are holding my wallet on this.
[One (M8) General] Bigal77:
Not sure what you guys are seeing...but I'm clearly seeing great results to whoever posted screen time....over 6hrs in all cases
[One (M8) General] :
Yep agree got near 7 hours screen time yesterday on WiFi all day though.
[One (M8) General] Basil3:
I've had to plug back in to do some flashing, but for an idea on my first day from a full charge.....Definitely better than M7.
[One (M8) General] NJGSII:
That's great even by just WiFi standards. Can't wait to see what results I get. So far the ones in here are definitely going to quiet the people were *****ing about battery size.
[One (M8) General] CandyAndy:

I know I said I'd post screen shots today when it died... however, it will take me to the evening to kill this thing.

Unplugged yesterday at work at 11:30am. Primarily texting, a couple phone calls, few pictures, browsed Reddit for awhile, and updated a few notes in Evernote. Also used the phone for my alarm this morning.

2.5 hours away from being 24 hours on battery and I'm at 48% with 2 hours and 23 minutes screen on.

Addition: This is on my first full charge.
[One (M8) General] shox22:
Your phone was awake 19 of 21 hours. You should look for that. There is a app which doesn´t let your phone go into deepsleep.
[One (M8) General] rotchcrocket04:
Hm, I can't believe I didn't even notice that. I thought GSam would be able to tell me that... maybe that is a Root Companion feature? I'm not sure how to check that out if I'm not rooted...? Do you know?

Battery on N5 is good. I believe that one can "train" their battery. If done correctly, it changes your battery life completely.
[One (M8) General] hutchy69:
I get a decent 2 days out of my M8 with average use (3h of streaming music per day, texts, email, browsing).

The same usage pattern on the N5 only lasted a day usually.
[One (M8) General] BerndM14:
Hmm 20% in 7 hours or so does seem a bit much. Since my last post yesterday to now I used another hour and 20 minutes of screen time and the battery only went down 16%. I went to bed and slept for 7 hours and the drain was only 3%with wifi on the whole time as well. Google play auto update was on to update my apps YouTube and HTC stuff... Don't know how your drain is so high ^_^ do you have some screen shots of usage?

[One (M8) General] OGhoul:
A come back?

I'm considering giving in to the siren song of the new One.

What do I have to do to achieve 2+ days of battery life on a charge? My M7 got pitiful battery life, even when running ARHD. Worse than the iPhone 4S it replaced (needed to charge mid-day).

Here's some background info:

iCloud account

3 Gmail accounts

Hotmail account

Twitter

Facebook

Instagram

I'm on AT&T, generally have 4 or more bars, and live on my own Wifi (with a hidden SSID) for 12+ hours a day.

I use(d):

Swiftkey

Flickr and Dropbox auto-upload

Hate the offical Gmail app, and would prefer to have one that was Fetch instead of Push. I can probably consolidate several of those email accounts into fewer Gmail accounts.
[One (M8) General] exSD:
I can't believe the user's in this thread.

Go run GSam for two days. Report back what your radio quality was like. That's the biggest factor in deciding battery life.

Have you tried using Wakelock Detector from the Google Play Store? You can then use Wakelock Terminator after you determined what you dont want keeping your device up. Also are using Greenify? Trust me Greenify helped tremendously.

Not really surprising though is it? Most would rather text these days it seems, BBM, Hangouts, Whatsapp(They recently got 500million downloads not?) and even locally a thing called "Mxit".

Everywhere you look there are people texting and messaging other people, not a lot of actual talking anymore. As for me...I just don't know a lot of people period so...lol

Heck to put in perspective...You even get some guys and girls that text their "loved" one while sitting in the same darn room as them. :eek: Yeah I know a couple like that.

[One (M8) General] yblaze8:
From a search I got that VDM client is a component of the kernel of your phone. VDM client is responsible for calls, CDMA and GPRS connections and everything that is related to calling capability.

Found that in a german Forum (Android-hilfe.de).

no energy saver, gps/wlan/mobile data on the whole time, ART runtime, bluetooth/nfc off.

Used for mostly ebooks the whole day, other than that, the normal stuff... messenger/surfing/emails/etc.

More than impressive, what this device can get out of merely 2600 mAh.

Can anyone beat that? :D
[One (M8) General] chrisosaur:
I'm getting, what I would consider, aweful life lately. I'm at work all day so I'll pop the screen on occasionally to check an email or text message. I had 50mins screen on today, used some popular apps (Facebook, Instagram, and a little reddit) and used the phone for a whopping 5 minutes. I've never used any battery saver or monitor apps before, so any help would be much appreciated. I'm jealous of the numbers I see here lol
[One (M8) General] yblaze8:
Maybe it has something to do with a stuck MMS or something. I would try a restart and monitor it again. Or maybe make a nandroid and try another kernel or even ROM and see if you having the same issue. Perhaps you need to do another clean flash of your ROM.

I don't have dont have that wakelock at all and I dont have ViperRom or Sprint. I'm on with at&t and have Kangakat ROM with ElementalX kernel installed, so I might not be much help.

Here's some battery life after converting my Telus m8 to gpe. Full conversion since I wanted latest Google updates.
[One (M8) General] EtherealRemnant:
Seriously? Never in my wildest dreams... Nothing special. WiFi on all day with LTE as the fall back, constant chatting through LINE messenger, some browsing, sync on, gps on, auto brightness.

To say I'm happy would be the understatement of the century. I don't think I'll get much more out of it. Also note it's only 87% of total usage. I rebooted to check hboot last night.

Seriously this phone blows away every expectation I ever had and I can finally use a screen on auto brightness now instead of setting it to very dim to stop the battery drain. I also took a few pictures with the camera, just some fast snaps. A few minutes with Brave Frontier to get my log in gifts but that's it.

It seems like this phone has crazy battery life unless the GPU gets pushed. When that happens, the battery life tanks. To be fair though, the GPU speed is a whopping 578MHz vs 400MHz in the M7 and the battery bump is minimal yet the phone still manages to get a good 20-35 percent more battery life depending on the game.

I've only had the phone since the 21st so it's possible these numbers may improve slightly but even if they don't, I couldn't be any more thrilled. Had I not done the reboot it would have come close to the eight hour mark easily I think.

EDIT: Here is the battery/signal map since that has been posted too.
[One (M8) General] Dreadsteel:
Hey guys, for those that have tried both the Google play edition roms and the sense rom, which did you have better battery life with?

Are the results just marginal or is it a big difference?

Thanks. Coming from the g2 so it's an adjustment for me on the battery life haha ?
[One (M8) General] exad:
Sense is noticeably better. No doubt about it.
[One (M8) General] SamVib:
How long does it take everyone to charge their phones? Today was the first time I was able to watch my phone charge, I always charge it before I go to bed. I've been watching it for the last 2 hours, and it's only at 43%. It died completely and I never actually turned it on. Is this normal?
[One (M8) General] yblaze8:
For me GPe was waay better. I was getting around 4.5hrs of SOT with 1.5hrs of talk after debloating Sense. With similar battery saving tricks on Kangakat rom and the ElementalX kernel I get 7.5hrs of SOT with 8% left on the battery.
[One (M8) General] Dreadsteel:
Hmm I'll have to check out the ROM. Been just running stock gpe with stock kernel
[One (M8) General] BerndM14:
:eek: That's way longer than my phone, it takes about 1.5 - 2hours from 0 - 100, yeah slow but seems way faster than what you're getting there.

My last charge I started just after 11:30PM it was at 3% then, by 2AM I could use it again, it was fully charged then, I just don't know for sure how long it had been at 100% though as I was playing games and watching youtube videos on the PC and didn't pay attention:eek:
[One (M8) General] yblaze8:
Mine goes from 8% to 100% in roughly 2hrs - 2.5 hrs.

Make sure you use the original HTC cable or a high quality charger with the same specs.

---------- Post added at 08:34 AM ---------- Previous post was at 08:23 AM ----------

I guess you can also try the kernel on your ROM first. I undervolted, kept the stock clock speeds, and turned off the magnetic sensor (I don't have a case that can utilize that sensor) through the aroma installer that comes with it.
[One (M8) General] Shebee:
Getting this phone tomorrow.

Having the same capacity battery as the S4 I'm positive it will be enough.

On the S4 the battery life is pretty crappy without rooting and uninstalling all 1000 unnecessary samsung BS apps.

I can get like 3.5-4h screen on time on my S4, maybe 3h or less now that I'm on 4.4.2 and unrooted.

No more samsung for me.
