@ Darth what is your take on this recent post about smartphone battery myths? http://news.yahoo.com/10-common-misconceptions-mobile-device-221237135.html
[One (M8) General] gull_s_777:
Standby battery usage is gone down the drain with lollipop update for me.

Almost looses 1% per hour.

So much for lollipop excitement. Guess i should start waiting for something like Lollipop 5.1 fix.
[One (M8) General] :
Smart article. IMHO... I agree with all of it. Location services alone won't do harm either really... But as soon as you have apps using it that you install... Another story.

?
[One (M8) General] :
Yet debates still go on here about some of those items. Especially over night charging... Which I do a lot. ?
[One (M8) General] ayyu3m:
Honestly, the battery life has halved after the lollipop update. My M8 use to get ~48hrs with light use on Kitkat 4.4.4. But now even after light use, the battery is arnd ~23-22hrs

[One (M8) General] Ntbook:
My HTC one is converted to DevEd. Will I have any troubles if I do a factory reset? Does a FR affects the root, s-off or any of that?

And after FR can I get my apps and config back with a TWRP backup or there is a better option for it?

Thanks in advance

I just updated 2 days ago my One M8 to 5.0.1 and my battery is charging very slow, like 20% in 30 mins. Before update, with 4.4.4, i didn't have this problem.
[One (M8) General] navid0308:
official HTC recommendation:

1. Plug phone into the wall charger that came with your phone

2. Turn it off, let it charge for ~10 mins

3. Press power+vol up+vol down and HOLD for TWO WHOLE MINUTES

4. Phone will constantly reboot each 15-20 seconds

5. After 2 minutes, let the 3 buttons go and let it charge to 100%

what this does: Reset battery charging logic

side effects: NONE
[One (M8) General] xTee:
I didn't know this. I will give a try. I hope it will work. Thank you!

I've googled awhile now but couldnt find a HTC Site. I guess the guy from the link didnt made this up. The solution is discussed on different android / phone related sites. Hope this helps.

If an official link exists, please share.

Edit: b2t: my Battery life is much better since upgrading to Android 5(stock). At easy usage it seems endless.

Just talked with HTC tech support i they gave me 2 procedures to solve some battery problems.

2nd procedure - they said to do this if the 1st procedure didn't work, but is not recommended to do it frequently

I put this prints to see the "authenticity" of conversation with HTC tech support.

No powersave turned on, this battery i got with powersave turned on last time, but wipe cache and a full battery charge with phone off does wonders

Well I did try, no difference after cache wiping.

I'll try charging it with the phone Off to see what happens... else, can I safely do a factory reset if my phone is converted to DevEd? (rooted, s-off)
[One (M8) General] macthehobo:
I was having massive battery drain after updating to Lollipop. I did a search on google and someone suggested (on another forum) to disable in-app sounds on FB Messenger.

Since I've done that the battery has been a lot better. Sorry for the lack of stats or screenshots to back it up, but maybe give it a try.
[One (M8) General] duskdiyebiri:
what apps are you using in daily usage?

social media, instant messengers, gaming, chrome surfing etc.
[One (M8) General] :
My Lollipop times.... ?
[One (M8) General] high_voltage:
Why not, I will give it a try tomorrow.

After updating to lolipop my screen on time dropped a lot. With 4.4 I got 7 hours and 20 minutes screen on time and whole day on battery(around 20-22 hours). After the update I barely get 6 hours screen on time. I am not rooted and stock for now. Maybe it's some app misbehaving on lolipop, but it's hard to track without root access. Thinking about reset and most likely will try out that soon...

Edit: First thing I notice after turning off in-app sound of fb msgr: The freezing of the app after sending new msg is gone and it works as it should. So, thanks as it was really annoying anyway! Will see about the battery life tomorrow. :)
[One (M8) General] Callliope:
Social media apps:facebook, Instagram, ask fm, snapchat, chrome etc
[One (M8) General] kartoonz:
i have noticed that since lollipop update charging has become relatively slow. Earlier if i would charge my phone from 22% - 100% it would barely take 2 hrs. However, now it takes upto 2.20hrs.

im on stock, non rooted. anyone else facing similar issues. Also the battery is draining quicker than before ( i can still scrape through the day). While gaming the drop in %age has increased from 2% to 4% per min :confused:

Ranting aside! the phone has become super quick and buttery smooth than before... kudos htc for super optimization and integration of lollipop!!

[One (M8) General] Callliope:
He did some reading on phone , that's why he have 8 hrs screen, 35% app usage is low
[One (M8) General] :
A lot of xda premium, browser and texts. Note the average times at the bottom... Since October. So not a one day high.

Mostly pointing out that with my setup and usage.... Kit Kat and lollipop times are the same. ?

Some say Lollipop is worse, so it's likely from features or apps I don't use. Track those things down and battery life should be no different on Lollipop. ?

And see the held awake time. Barely any.
[One (M8) General] high_voltage:
Most likely apps that are not optimized for lolipop and misbehave leading to constant battery drain.
[One (M8) General] navid0308:

[One (M8) General] rizevnarastek:

[One (M8) General] dragonflame8712:
What is this system(adsprpcd) tahts causing battery drain its happening after updgrading to lollipop firmware.

"audio on " in usage details keeps running even though I'm not playing any video or audio I.e when I refresh status the audio on time is increased
[One (M8) General] CanBostanci:
Same thing for me. I dont use my phone nowadays because I'm in vacation, and Google Services are draining battery like hell even with the fact I dont even open my phone too often.
[One (M8) General] :
Audio on just about always is normal. ?
[One (M8) General] :
That would be because there's no other usage to knock it's percent down. Also normal behavior. ?

Need gsam screen shots, including held awake time and times waking device to see if its out of line or not.
[One (M8) General] kartoonz:
battery life is ridiculous on lollipop....

1) while playing games it discharges quicker, same with any other task

2) charging time has become slow

3) phone heats up like never before

im taking it back to the service center to restore back to kitkat.

im on stock and non rooted
[One (M8) General] navid0308:
I know this is not much to go on but 4% down already and most of it is because of standby drain!

I'm not rooted so I can't post further information
[One (M8) General] :
A couple hours doesn't say much. Post again when you're down to like 10 percent left or so. ?

And check out wakelock detectors pc version. It can check wakelocks for Non rooted devices.

[One (M8) General] mxisme:
M8 stock not rooted drains 2% per hour in STANDBY no matter what

Dear all

I've seen some very impressive stats posted here. When I got my M8 in April last year, for the first weeks and maybe months the battery life was very impressive. I remember going to bed with over 50% left, and I consider myself a heavy user.

It seems to me that after either the 4.4.4. update [5.0 has not yet been released to the EE network in the UK] , or some other update, something changed to the worse. I don't think I can get more than 3-3.5 hrs of SOT anymore.

I tried factory resetting and not installing any apps. I tried changing all the usual suspects - disabling Location Services (or leaving only GPS on), disabling wifi scanning, stopping all syncs [I got only a Google account. Twitter, instagram and linkedid have no sync and no notifications], disabling google search/google now, disabling google play music which I use (this was recommended somewhere)... Nothing helps!

Key features of the drain are:

- stock firmware, not rooted, wakelock detector activated by staring it through ADB from a laptop

- drain from 1.7%to 2.2% per hour in standby. Even in airplane mode the drain is around 2% [unless the phone is fresh from a restart]

- m8's power saver, and even extreme power saver, make no difference.

- m8's battery usage app shows 'Phone Idle', 'Cell Standby', 'Android OS'. GSAM shows 'Android OS', 'Kernel'. Wakelock detector does not show anything suspicious.

I run a few tests and hoped someone could give an advise. Screenshots of GSAM, Wakelock Detector, and HTC battery app are available here - https://drive.google.com/folderview?id=0B9IearWfeT2EfjVVbkxkdl84YXltOGNNR2VFbXhVYVlESGhlSFB1ekIteloyajc1aVJQbWs&usp=sharing

Some key stats:

1) Airplane mode standby at night - 10% drain in 6 hours:

2) 5% drain in standby in 2.5hr: Wifi set to 'Keep wifi on during sleep = only when charged', autosync disabled, only GPS kept on

3) 6% drain in 3 hours when offline and standby:
[One (M8) General] :
All seems pretty good to me! ?
[One (M8) General] :
Are you rooted? If so, need gsam root companion installed and let's see held awake time and times waking device. Also kernel wakelocks.

If you're not rooted, try wakelock detectors pc version.

Also, you have data and WiFi off? If you have location services on, and all those social apps running, you're standby time will suffer. Try location off.

Also greenify social apps if you can. You won't get notifications though.

If you have all the bells and whistles enabled, your standby won't be as good. Though, it's still pretty high I'd say.
[One (M8) General] duskdiyebiri:
I dimmed screen, used 2G network most of the time. Location services is battery saving mode.

Mostly Instant messengers and social media

I used power saving mode %40 of this time
[One (M8) General] :
2g will hurt you more than help with social apps trying to update over it. And 2G will hurt with location services on and using data.
[One (M8) General] TwistyValhalla:
Battery life on Lollipop isn't bad for me but it does seem KitKat was a bit better. I'm wondering is this is due to Smart Lock. I have trusted location turned on and most likely the phone periodically checks for location on the device. I also see the GPS notification icon flash for a fraction of a second on the home screen after I unlock the device - is it just me or others seeing this also?
[One (M8) General] duskdiyebiri:
At the end of the day
[One (M8) General] An0n1mUs:
My battery durability has been halved since 4~5 days ago. I am using Lollipop about ten days, and at first usage was normal, about 5:30~6h at the end of my 2 day usage. Since Lollipop I have used a Pebble and for the first days the battery impact was almost nonexistent. When I updated to Lollipop I cleared the cache. Any tips, because this is almost unusable.

BTW, I don't use location services, nor 4G because the coverage is poor at home, where I spend most of my time, and the phone is almost always connected to WiFi. I don't use Facebook and Skype.

[IMG="battery1"]https://i.imgur.com/6H62DPF.png[/IMG][IMG="battery2"]https://i.imgur.com/pFwpjqn.png[/IMG]

IMO, "Kernel (Android OS)" and "Android System" seem to be the culprit, because i didn't notice them in 4.4.

Sent from my HTC One_M8
[One (M8) General] :
Battery guru and similar battery "saver" apps usually hurt your battery life more than they help. All they do is cause wake locks and make your data/WiFi have to constantly initialize every time you use them. With no outstanding issues, data and WiFi left on should cause no harm. ?

Holy crap, you got 13+ hrs of SoT max?

Did you just put it on a black screen, airplane mode, minimum brightness and left the screen on in a drawer?

What's your usage pattern, apps, BlinkFeed, sync?

20hrs with 6hrs SoT and 9% still left is a great result.

[One (M8) General] goodboy.19841010:
guys I need your help.. after lollipop update , "kernel" with 20% and "android system" with 15% are always topping my app sucker list. while in my mother nexus 5 (android 5.0, not 5.0.1 ), these 2 are always stalking aroud 7% each one. I have done factory reset, every sinking is off,always scanning in wifi is off,gps set on battery saving mode,on 2g (not 3g lte),internet just on wifi

in kitkat I had a far superior battery life. I am s-on and unrooted. every thing is stock

please help me.I want my m8 battery life to be as impressive as it was on kitkat times :(
[One (M8) General] :
Try with location off and use lte/3g...unless your signal is horrible. Usually 2G hurts more than it helps, cause everything takes longer.

And screen shots are best to help. Try gsam. And even wakelock detectors pc version. It can see wakelocks without root. ?

i was experiencing similar issues after lollipop update, however i reset the phone to factory settings and now battery is a bit better than before... also update all the installed apps on your phone from playstore
[One (M8) General] :
You have a lot working against you here. Location on I'm guessing, Bluetooth on, social apps, gaming.... And a weak signal by the looks of it. That's a killer. And likely your main issue.

Have a look at posts 1 to 4 in the battery help thread in my signature. Lots of info there. ?
[One (M8) General] Nubzori:
Indeed, turned location off yesterday and thus app sucker doesn't show Kernel or Android System as top drainers anymore. Now it's mainly games.

At my school LTE is way better than 1 bars at my home, where I usually force LTE on.

Social apps and bluetooth (for my moto 360) are on all the time and I even have my IRC client connected mostly 24/7, if you don't count occasional disconnects due to network change etc.

Your tips are very nice but I still think kitkat has better battery life than lollipop.
[One (M8) General] :
Perhaps certain situations are better on kit Kat. Remember, Lollipop is new, so updates may come. But a lot of people, myself included... Have seen no difference. But perhaps I'm not using/doing the things that may be worse on Lollipop.

Gaming is hard on battery no matter what version though, and the 360 may not be helping either.

Try one full day with zero gaming and no 360, and Bluetooth off.

Just to compare. ?

Seeing your held awake time and times waking device and kernel wakelocks would be helpful, and the graph that shows signal strength. Cause you definitely are getting terrible battery life.

[One (M8) General] TwistyValhalla:
Finally starting to get good battery life on Lollipop (knock on wood). Definitely on par with Kit-Kat now or maybe even a bit better! I think the new Google Play Services (6.7) might be helping but I could be wrong. I don't use battery monitoring apps so no stats but I'm currently at 87% battery left for the day (~9 hrs on battery since this morning, ~1 hr screen on - news, email, messaging, no gaming, all sync on, auto brightness, LTE, wi-fi off, location reporting off, Bluetooth connected to UP24).
