Android system and kernel (Android OS) are my two highest usage apps under idle. Also have loads of alarms from google play services 7.0.99 : 1.3/minute according to BBS. That seems to be the cause of my excessive idle drain. Lose around 1-2% per hour. Weird because I denied keep wake for GPS in appops.

However my screen on time is amazing. 4-6h with auto brightness. Exponentially more with limited brightness. However this is limited by the idle drain.

Running IC 7.1.2, stock kernel. Might try elemental x...

Turn off all permissions in app ops or disable their services using this app here
[One (M8) General] Nokiacrazi:
The problem is that using this I often unleash more wakelocks or break some functionality. I use his other app which also allows you to disable receivers. I haven't found a comprehensive guide to using this for maximizing battery life while keeping essential notifications (hangouts + gmail). Don't know if you know exactly what I should be disabling? Thanks.
[One (M8) General] Bobbi lim:
I never had any issues with getting more wakelocks with disabling services for a specific app. What I can think of is this, whatever app that's causing the wakelock wants to use google location service feature made into google play services apps and frameworks and when you disable location services, you break that app feature which results in it trying very hard to make it connect but couldn't thus causing the wakelocks that you mention :)

I disable google play services entirely and I don't have much wakelocks except for whatsapp and radio connectivity ;)
[One (M8) General] Nokiacrazi:
I know it's probably a little much to ask, but I'm sure others and myself would be grateful if you can list exactly what you disabled regarding google play service? Thanks.

P.S. while using power saver (CPU, screen, vibration) I got 3h sot over 27h. Had 2hr wakelocks.

According to gsam 30% for 3h sot 46% for 24h "idle", so almost 2%/h idle...

cell standby

Why is cell radio eating my battery? I had data and WiFi off overnight. My signal seems okay too. Anyone? This drain is driving me mad :crying:
[One (M8) General] go0gl3:
Hi you can pretty much turn off everything in apps ops (im rooted but unsure if this makes a difference). However turning off location (top) and keep awake (bottom) made a huge difference

I did the same with android system
[One (M8) General] Bobbi lim:
I'm getting lazier and lazier with disabling services that I just disable google play services and google play store to fix my battery drains ;)

It's fine.... Or it could be that your network ain't that good at home. Turn on airplane mode and see how :rolleyes:

Cell radio still drains battery at like 0.6% per hour after I take sim out, turn off all data/wifi connectivity....does that make sense?

Hey, any ideas on what is drinking so much juice from my device?
[One (M8) General] high_voltage:
media scanning. Either search here for mp3 check tool that will fix problematic mp3's or second option is to go developer settings and turn off nuplayer.
[One (M8) General] TempestZ:
Can someone explain to me the " light: "

Line in android system usage? Does it mean back light? Flash light? My guess is back light but I would swear I never saw it before or it was at 0

Edit: Look it apears into sensor time so it's probably light sensor.
[One (M8) General] Bobbi lim:
With mobile data on, I can have 0.8%/hr standby though.. You might want to take a look at your settings, maybe NFC wasn't off etc... :rolleyes:

The other way to check is to see your apps, maybe of them you installed is a rogue app that sucks your battery :silly:

---------- Post added at 04:09 PM ---------- Previous post was at 04:08 PM ----------

Don't mind the light. Mine is as high as the standby time on my phone and even if it I managed to lower it (can't remember doing what), I don't see any increase/decrease in battery life :cool:

---------- Post added at 04:12 PM ---------- Previous post was at 04:09 PM ----------

Agree on [MENTION=4126040]high_voltage[/MENTION] on that. My suggestion is copy out your photos, music and "other info :silly:" out of your SD card/ internal storage (respectively) and using TWRP to format the storages (be it internal or SD card) and place those backed up items and see how standby battery goes. And if you want to be safe, make a full wipe as well ;)
[One (M8) General] navid0308:
I use mp3 val for all my music

I deleted all folders other than my files from sd from pc while it's in twrp(that way I can delete android secure)

Then I used the RUU.exe which wiped my internal storage

I highly doubt anything in my phones storage is messing with my battery

On gsam app sucker I get kernel and android os as top drainers. Then 20-30% gap and some of the apps I use...
[One (M8) General] Bobbi lim:
Sometimes it might be your files on your device's storage that's causing the issues :rolleyes:

Hello guys! Need some help with wakelocks! I dont know how to get rid of them! After receiving 5.1 update battery seems to drain faster! Gsam shows only 2h40min sot! On 5.0.1 was around 5h!
[One (M8) General] high_voltage:
Give it a few days for the rom to settle itself down. Most likely it's caching, etc.

[One (M8) General] Bobbi lim:
Radio is not something we can fix unless you get a new sim card from a different carrier. And that wasn't meant for you :rolleyes:
[One (M8) General] badboy47:
Good.
[One (M8) General] Nevii:
Well, I have just pulled out my SDCard (which is occupied with 46GB's of music) and that didn't fixed it. My Internal SD is also empty.

Also I have noticed that this thing drinks more juice on SkyDragon 7.0 than on InsertCoin 7.1.2 which i was using before.
[One (M8) General] forever_lol:
I have also this annoying problem with wakelocks, and I've no idea how to get rid of them. My cpu just doesn´t go to deep sleep as it should. My old nexus 4 sleeps like a baby- above 95% of time in deep sleep? - no problem at all. On the other hand my M8 - with pretty much the same configuration (tested on both sense and gpe 5.1), with the same number of application installed and at the same place hardly gets 70% deep sleep. So uninstalling, deactivating the half of stuff is not an option for me.

I use both GSAm and Better Battery Statts and all I can read from there is that the vast majority of wakelocks are system(kernel) related. The biggest battery drain i observed so far is at my work (40% of time spent at work device is awake even though it´s connected to wifi.) As mentioned above my old nexus 4 doesn't seem to have such issue. LTE seems to be only rational explanation of such significant difference. I'll try to turn mobile data (and then wifi) off totally and see if the problem is still there..

If I could find the way to get rid of these wakelocks battery time would be very very good. Never experienced better screen on time to be honest. On the other hand I've never experienced such lousy screen off time.
[One (M8) General] Bobbi lim:
Based on what you said, there could be some possibilities. Your scenario is something I faced a few weeks back and made me spent 3 weeks to fix it. But as there's not much solid evidence in your post. I can only narrow down to these 4 possible scenarios.

1. Your CPU settings might have been tuned wrongly or something is acting your up your CPU (eg, a kernel app)

2. You have installed a rogue app or a app that kills battery (eg, whatsapp, facebook etc...)

3. You have some broken files on your storages and thus causing a mediaserver wakelock.

4. Your phone is disconnected to the respective networks and thus phone is kept awake to try and connect.

Possible fix for the above scenario:

1. Uninstall your kernel app and leave CPU settings stock.

2. Uninstall all your apps, wipe cache and dalvik cache and install your essential apps.

3. Backup your pictures and other files that you want on your phone and wipe your storages in TWRP.

4. Turn on airplane mode for 30min or so and see if its of any help.

Poor battery life since Sense Home update

Has anyone noticed poor battery life since getting the recent Sense Home/Lock Screen update? I have noticed a marked decrease especially when the screen is on. If so, did anyone find any solutions?

best wishes,

Ashley
[One (M8) General] Snah001:
Well here is the battery life unchanged.

Still easy an 5 hours screentime minimum.
[One (M8) General] forever_lol:
Thank you very much for your helpful post especially that I haven't provided you with more specific information about my device's configuration.

Right now I use all the way stock (sure s-off and unlocked bl). So we have to eliminate kernel applications like trickster mod etc cos my m8´s not even rooted at the moment. All partitions (except external SD) were formatted/erased yesterday. I haven´t tested formatting my sd card yet, but it´s definitely worth a shot.

Today I switched mobile data and wifi off when I was at the office, and results are amazing. CPU - 95% in deep sleep. It looks like mobile data is somehow still in use even when I am connected to company wireless network.

Three first screenshots - rooted stock, wifi & mobile data on

Next two screenshots - unrooted stock, wifi&mobile data off

I'll keep testing, I'm not 100% sure yet but so far it looks like switching mobile data off when you're connected via WIFI is not that bad idea.

so 4.

seems to be a case here.

On the contrary, since the Sense Home update my battery life seems to have improved.

Weird enough, after the HTC weather app update, it's even better. Makes no sense to me.

I don't know but why is my kernel usage is to high? Wakelocks?

Shame on HTC. where is my RUU? :D
[One (M8) General] Bobbi lim:
Sense launcher couldn't be the cause of battery draining as the app itself is partially flawless. Only thing I can suggest you is to head over to settings > data usage and disable background data for Sense Home :p

---------- Post added at 09:33 PM ---------- Previous post was at 09:32 PM ----------

I know, never regretted getting this device :p

---------- Post added at 09:38 PM ---------- Previous post was at 09:33 PM ----------

I can't read your stats much as it's not in english but from the looks of things, network is a battery killer for you in standby! :silly: If your phone is working fine, it should drop around 1 - 2%/hr and 2.8% unless there's wakeups continuously.

My suggestion is to go turn off background data for apps that you don't need in settings > data usage. After which leave your mobile data on and see how your battery fares... Might either be a rogue app causing your battery drain or your networks... My recommendation would be turn on power saver but untick "turn off mobile data" and check in settings > wifi > advance > scanning always available :cool:

Wakelock is a damn neccessity after all! :rolleyes: And mobile radio active can be due to a lot of issues, like app requesting the phone to sync, searching for networks etc... :rolleyes:

[One (M8) General] Bobbi lim:
If you've been following long enough, you should know very well that its a known issue on the M8. Kernel and Android OS are higher as compared to KK. And I wasn't being cocky. If I was, I would have give you a reply that would have throw you off and have it as a direct insult to your face and be glad I didn't. There's a clear line being sarcastic and cocky.

For those of you with kernel wakelocks - are you using a sd card?

If so - are you having a mediaserver wakelock?

My mediaserver was wakelocking a lot and I scanned my sd card for mp3 errors using: http://mp3val.sourceforge.net/

I found a lot of problems and either fixed them or deleted the bad mp3 files. I'll see if this helps me out at all.

I have excellent battery life. I am running a lightly modified stock sense rom alongside Flar2's ElementalX kernel of course, which is the only thing that would allow me to have 5 to 5-1/2 hours of straight Ingress time on the Nexus 5. If you are familiar with Ingress, then you know that is outdoor, high brightness with constant GPS & LTE connectivity. Before EX on the Nexus 5, maybe 3 hours. The M8 Ex kernel is still early beta, but I'll take it any day over stock. Give it a few weeks if you are worried about beta status & you will be golden.

[One (M8) General] ryno9100:
I've been VERY impressed with my battery life. Let's be honest, with a 3600 mah battery (only 300 mah bigger than the HTC One M7) I was expecting that to be the breaking point of this phone for me. I love everything else about it (mostly, not a fan of on screen buttons, but that can be altered), and was scared about the 2600 mah.

I have ran this phone VERY heavily for a solid 4 or 5 days. I charge it when I go to bed at night, and it only gets charged any more if I transfer files from my work computer to the phone (which is why I can't give an accurate GSOM screenshot). That usually doesn't last longer than a few minutes.

Anyways. I take the phone off the charger at about 6 AM, and go to work, then school, then home again. I use it heavily at work, browsing 9GAG -- I mean working... making phone calls, texting my fiancé (a LOT with the wedding coming up), and playing music and youtube videos in the 2 and a half hours between work and class. I play music via Spotify radio for the hour drive to work and to home, and every night when I get home and go to bed, I still manage to have 20%+ battery life. And all this WITHOUT power saver mode. I use Location services only for weather, and am on LTE when anywhere but home. I am thoroughly impressed.

[One (M8) General] Shan89:
InsertCoin rom, 1bar from toggles brightness ( 37% actually ), power saver, greenify + amplify + apps ops on few apps like Google play store etc. The screenshot you've quoted is without amplify.

This is my most recent with amplify and wakelocks + battery life are looking much better considering how many calls I've had + poor signal reception.
[One (M8) General] edios123:
That's great. You seem to be a lucky person!

I'll try going back to Kitkat because some has posted some astonishing screen on times with Kitkat (12 hours). I wasn't able to try Kitkat because I got the phone recently. I just want to know if Kitkat provides that much improvement in battery.
[One (M8) General] Bobbi lim:
Kitkat has been roviding astonishing battery life compared to Lollipop but even if you've just gotten your phone, you can still flash a kitkat ROM but make sure it's for 4.4.4 Sense 6 ROM. Any other ROM that is below might give you errors like wifi not working and so on... :silly:

As for his battery life, it's been a common scene for quite a while and that's my normal stats when I'm in school or at home regardless whether I'm using wifi or data :cool:
[One (M8) General] forever_lol:
That´s my normal two days usage on one charge. No battery saver on, auto brightness on, automatic sync on. There were certainly moments when either wifi or data were on (e.g. I travelled by bus and used one app to buy a ticket -> data had to be switched on on the whole route). Well, nothing to brag but nothing to be particularly concerned either. Wakelocks are something to work on in future. They are obviously inevitable but I believe they will be reduced after more testing and more radical measures applied :)

to sum up 2 days, over 3 hours sot, connected, around 85 % of deep sleep and still 25% remaining. As I said nothing to brag but honestly I cannot remember better battery life on any of my previous smartphones.
[One (M8) General] gtfour88:
This is the most I can get out of my M8. My M8: completely stock, non-rooted, Android 5.0.1, Sense 6. WiFi on (keep on) for around 10 hours when at home, otherwise mobile data always on. Good reception areas all day. Phone is around 9 months old, charged almost every night and sometimes twice a day (in afternoon) if heavily used. Power saver only on at 15%, no battery saving apps. No auto sync, brightness 97% of the SOT at 1 bar, turned off background data for HTC sense home, force stop Faceboook app. Play SimCity most otherwise web browsing. Very little phone calls.

yep just tried it. seems pretty effective (and stable) for an alpha release. powernap + amplify has dropped idle discharge (when screen off) to about 0.5% / hour without too much effort.
