I got my second hand m8 recently that was bought originaly in February this year. I'm getting very satisfying sot results that I never could achieve with my old m7. Today I'm testing it with power saver on all the time as I can't see any negative impact to performance while being in saver mode.

100% stock, unrooted, no fb or other social apps, Auto sync off - exactly same settings that I have been using on my m7. Over 12 hrs on 3g. Screen inside set between 10-20% as this is completely enough on m8.

I've got an eu m8 s-off-ed with wwe firmware and os. But since I'm in Bangladesh, I think the frequency bands aren't matching and so I get relatively high drains due to network despite having good signal. About 15% standby drain in 8 hours. I'm thinking about changing my firmware to the Taiwanese or Hong Kong edition because some of my friends say they get better battery life cause their HTC device is from Hong Kong or some place in Asia. Will this have any side effects? I know I gotta change my mid but my main concern is some of the Asian m8s have 2.5ghz chipsets.

so i will share my battery life.. i was on stock lollipop unrooted and battery life was not good high drains etc u all know that but recently i rooted and installed Leedroid Rom and lONElyX #036 Kernel and Changed Governor to IntelliDemand. now i am getting 5.5 hours screen times with full day use including one hour of youtube and one hour gaming as well.

my settings are: 35 % brightness, wifi on, 3g/4g off, good signal reception, location services are on and on battery saving mode No over or undercloking etc.. I suggest you all who are having poor battery life to give that a try.

Check for excessive wakelocks. I have been able to get dramatically better battery life by disabling them for services that don't really need them. Unfortunately, a lot of services are rolled into Android Core Apps.

For reference, I'm on 5.0.1 (Developer Edition). My highest usage at the moment is the Play Store (15.7%) (because I updated a few apps this morning while I was still on WiFi), followed by the kernel (10.1%), Android system (8.0%) and Mail (7.9%). Android Core Apps are showing 0.1%

If you use it correctly, it won't cause any lag AT ALL, they may cause ramdon reboots, but if you configure them good they will be okay, like mine. It's undervolt not underclock...

I'm on stock kernel. All i use is greenify, nothing else. Auto brightness, always on powersaver since i seldom play games on my phone, i only turn wifi when i use the phone, i turn off when i don't use it. Usually, facebook, instagram, web browsing and xda that's taking my time.
[One (M8) General] imfuzzyyy:
the f*ck? stock kernel? and no magic? 8HRS SOT seems impossible
[One (M8) General] gelo01:
Today i'm having cough and colds so i had my intimate time with my M8 almost the whole day. I think it's very possible. Stock kernel, yes. Underclocking and undervolting is non sense. Stock kernel is just optimized as it is. Well, it's Greenify's magic i think..
[One (M8) General] edios123:
Can you please turn off powers save and post here the results? I flashed that ROM after seeing your screenshot and the battery a little (very very little) better than other ROMs. And the standby drain is horrible. Don't know what is causing the drain. Using Amplify, Greenify and Power Nap. Wake lock detector shows no major wake lock.
[One (M8) General] imfuzzyyy:
I see Im using greenify+amplify also Im on SD V9 with elemental X kernel max is 4hrs SOT maybe my battery is weak for long time now

Mostly FB, xda, YT and internet. I don't game the whole day.
[One (M8) General] gelo01:
Maybe you have just installed the ROM? Give it some time to settle down. Standby drain is pretty normal i guess. 30min-1hr. I'm charging the phone right now, i won't use powersaver next time to test if the difference is significant.

Well, i treat my battery like a baby. I charge my phone when i see "please connect your charger", usually at 15%, i don't always drain my phone unless i'm going to record my battery stats until 1%. Plus i limit my phone usage while charging my phone. No wifi, no games, no calls, mostly text message only. I don't charge it overnight to prevent "over" charging. That's about it..

[One (M8) General] XavC:
LeeDroid 7.4.2. with its' normal kernel. Needless to say turned off all syncs, all animations off, screen brightness as low as I could bare with, power saving on, GPS only location, no mock locations etc. Performance is still great and I'm getting a LOT more juice out of it :D.
[One (M8) General] Richylitschy:
Haha, nice. Only wifi or 4g/3g too? cheers
[One (M8) General] Alec2435:
The battery for me really started to degrade after about 2/3 of a year I was even able to pull off a warranty replacement because of how far it degraded.
[One (M8) General] XavC:
kommt drauf an ;).

The stats I posted were after a full trip from Amsterdam to Cologne, where I currently live. In the Netherlands I use 4G, even when at home and even when there's wifi spots (20GB data bundle). Pretty stable signal throughout whole country as well (3-4 bars constant). In Germany I run 3G except for when home and @ uni. Signal usually is full strength, but really crappy when traveling due to remote areas. So it was pretty stressy on the battery ;).

Now I'm at home I was on WiFi nearly all day. Current stats are:

49% with 13h 50 mins on battery. WiFi on 13h 50m ( I don't switch it off when leaving home ).

Awake: 4h 16m

Stay Awake: 2h 3m

Screen On: 2h 12m

I'm looking to crank more out of this with minimum performance loss, so I'll go ahead and see if I can tweak the governor and undervolt a bit. There's still more juice to be gained :D.

Prognosis: About 13 hours left.
[One (M8) General] Richylitschy:
endlich mal ein Landsmann beim M8 ;)

im currently on Srom with tweaked interactive governor. I get 5hrs of SoT in 1 day usage, and about 4 to 3 1/2hrs of SoT in 2 days of usage, so pretty good!

Though, my last phone was a LG G2... yes, the battery was bigger, but the M8 has the new 801 SoC. I'm a little bit dissapointed with the battery life, tbh.

EDIT: all settings achieved with half/half WIFI and 4G, all syncs enabled, no power saving method.

Though, i cant seem to figure out how some guys in this forum get about 6-7hrs of SoT with 4G and Wifi...
[One (M8) General] XavC:
Bin aber kein Deutscher ;). NL :p.

Wow, that's some impressive stat as well.

I think you should be able to get more SOT with all syncs disabled and power saving on. If it'll bring you 2-3 extra hours that'd be sick, but I doubt it. They might have some extra tweaks and use Greenify etc. Maybe this edited GPservices as well, to prevent a lot of ****ty wakelocks etc.
[One (M8) General] JellyKitkatLoli:
Clumsy1991's and LeeDroid's kernel is AMAZING.

I have never had such a great standby time after 3 cycles, simply put in six to seven hours I've only lost 2~3% on standby whilst my LED was blinking and WiFi was on, and the SoT is wonderful although I don't like relying on SoT for measurement as it's too random at times.

A little reminder of how kitkat was ... Good old times

Now with same usage i get half of this time, even with 3h wakelocks kit kat was the best
[One (M8) General] :
I have to agree. Same setup as always and usage, and I went from almost 8 hour SoT average on kitkat, to about 6 on lollipop. Near 2 hour loss.

I may even go back to KK.... I don't really care what Android version I'm on. Whatever works best for me I say. :good:
[One (M8) General] SeviStein:

Rare phone usage

Auto screen brightness on :

Stock rooted & stock kernel with some bloatware removed/frozen.

Can you guys recommend any kernel/roms with low battery usage(no powerusing, below normal probably.)? I may take a look at Lee
[One (M8) General] high_voltage:
Nothing more to say. Btw, the 12h SOT was with a lot of chat, but I always got 8h SOT and 22h on battery with heavy usage (twitch, youtube, chrome, facebook, viber, few short calls, autobrightness on max slider, 3g data and 3-4h on it active, etc...) and that without any tweaking. Now the standby battery life is a lot worse, 3g data usage totally kills battery compared to kitkat, SOT is reduced to 6:30 instead of 8+ and that with tweaking. Pfff... :) btw, those screens are ON STOCK. :D
[One (M8) General] high_voltage:
Same for me if I use the phone the same way as before - from 8h and little above to 6 hours and little above... :/
[One (M8) General] rj.camargo:
Hey guys, I've been getting mediocre battery life. For some reasons my phone won't go t deep sleep even though there are no apps that are waking the device. This pictures wre taken when I had 62% battery. Only 1:30 of SOT. I'm on good LTE most of the time, and bluetooth on all the time syncing with miband (Just got it last week and before that the battery life was the same).

So I have a hist load of kernel wakelocks but no partial wake lock. Anybody knows the cause? I'm also on a GPE based rom with ElementalX Kernel.

Please someone give some light in this, it's driving me crazy.
[One (M8) General] :
It's app wakelocks you need to look at. And you need to be rooted to do that.

If you are rooted, try gsam app, and install and run gsam root companion as well. Then go from 100 to very Low Battery percentage and go into app usage section, click the drop down and check times waking device and held awake time.

If you aren't rooted, try using Wakelock detectors PC version. It doesn't need root. It uses ADB to see wakelocks.

:good:
[One (M8) General] rj.camargo:
So you're saying that I don't have to worry about that kernel wakelocks? I do have Gsam installed with the root companion, so I will wait until my battery is very low to report back with the info.

Thanks
[One (M8) General] :
Well, I personally know gsam, not much experience with BBS.

Show me a shot of gsam main screen, times waking device and held awake time... And kernel wakelocks.... And we'll see what it says.

It could be the kernel wakelocks. But that one is tough to solve, if you search on it, you'll see some ideas... But a rough one. Usually a reflash or a different kernel would be the advice you'd get on that.
[One (M8) General] pillopoulos:
I see that my kernel keeps my device from not getting into deep sleep. What could I do about that?
[One (M8) General] leandronb:
Hi guys, i am having only average battery life with my m8, 4-4,5 hours sot after 16 hours.

I always had excellent battery life, standby times are very good, but when I started using my apps like, feedly, twitter, g+, instagram, YouTube, chrome my battery starts draining a lot faster.

My phone gets warmer and even using the phone intensively I can't get more than 5 hours sot. I always use auto brightness with slider on max, sync on, Google now off, location battery saver, history off.

Don't matter what ROM, came from gpe and battery is the same. Just for testing I disabled everything, sync, brightness lowest, location off and standby drain is almost zero but sot still 4,5 hours max.

I see people getting more than 8 hours, gsmarena shows 12 hours of web browsing, and I already achieved 9 hours playing a TV show in mx player.

So any of these apps are draining my battery? Every time I use chrome or YouTube I notice that battery drains faster, so is there anything I can do to achieve 8 hours sot with normal usage? Thanks.
[One (M8) General] navid0308:
however nice and smooth chrome is, it drinks up juice several times faster than the stock HTC browser :\
[One (M8) General] JellyKitkatLoli:
Yeah Chrome is horrible when it comes to battery life, I suggest the AOSP Browser or HTC Internet or Naked browser or Next/Javelin.
[One (M8) General] leandronb:
since my old galaxy nexus chrome was heavy at battery, but some browsers do not load some plugins in sites and others are pretty lag in others, chrome is always consistent, maybe that is why it uses more battery.

another thing that uses a lot of battery is the boomsound speakers. i listen a lot to podcasts, and was using podstore, and noticed that battery was draining fast, even with screen off, so i bought pocket casts and same problem, google play music had this problem too so i noticed that was not the apps, it was the speakers, also i was not streaming, only files saved to device.

i think that since kitkat all roms have audio tunneling enabled to minimize the battery drain playing music, can anyone confirm this? does boomsound drains battery faster?

I know there's a way to achieve even lower kernel usage. People are posting 30% app usage rates. The kernel - probably- accounting roughly 20% of that (if they would post pics of app usage).

Still looking for some other answers if anyone has ideas.
