OTA battery drain [XXJVK]

Are you having high battery drain with XXJVK firmware, or any other 2.2.1 firmware?
Does your Battery Use shows high CPU usage time on Android OS?
Then, check if you ever had Software Updates logged in! I noticed high battery usage once I logged in for OTA updates. Possibly, the device is retrying the connection to update server (which will always return timeout). You can see the Software Update service running all the time once you logged in.
If you have logged in Software Updates, go Settings->Applications->Manage Application->All->Software Update->Clear Data
Once you have logged out from Software Updates, the service disappears and personally, battery life doubled.

Thanks, i will try it!
It really could be the last chance to solve my idle-drain-prob.
i'll report back.
//edit: cleared data, service automatically stopped. i'll report back tomorrow if it solves my drain-thing.

Yup i had it running too since boot.. cleared data and will report back

Let's hope this is the answer. I've just took the drastic measure of doing a hard reset and now battery drain is pretty much zero and phone is idle when screen is off. I'll keep installing and enabling things and see what takes more battery.

Very interesting, I did check if there were any updates, and I suffered from random battery drain. At first I suspected Google Maps/Navigation, but you could be right. I started Maps, and Navigation, killed en cleared OTA, and I am monitoring the battery.

I have found that when i use the built in task manager to "clear memory" as soon as i have done that the battery drains alot faster and my android OS in battery stats goes through the roof (from 5% to something like 14%). It has been running fine since yesterday and i cleared memory only to find my battery went very quickly from 28% to 9%. I rebooted the device and all is well, i wont be using that option anymore
After installing jvk full I installed jve modem, rooted and did battery stats wipe and battery issues went away.

i lost 25% over night in airplane mode
background & sync = off.

after clearing dalvik cache & battery recalibration using battery calibrator from market i have 5-7% drain per night, and 30-40% per day... last battery time was 2d 19h 14m, with some calls, some games, some wi-fi and some hsdpa & with weather widget update every hour.
info
i9000 + JVK (repartition 512, with bootloader) + CF Root
P.S before clearing dalvik cache & battery recalibration with same use i have maximum battery life - 23h

Clear the data for "Samsung Account".

There's something very wrong with your phone, either your battery's shot or there's a rogue program draining it, you shouldn't lose more than 1-2% overnight in airplane mode.

Same problem here. I hate this device...

Is it just me that think battery life is much better than on froyo?

I have no battery drain since i upgraded to jvk.

I'm seeing huge battery drain like others, sometimes more that 50% in a few hours doing absolutely nothing, wifi & 3G off and OS takes up to 60% of the battery usage. I never activated Automatice Updates since I flashed JVK. I am now on Darky's v10RC3. Only a few people are having such problems, most users say they are experiencing their best battery life ever.
I noticed that this drain always happened to me after I used Maps / Navigation. So I suspect them to create problems, maybe kicking off Software Update in a bad way. And rebooting stops the drain (it once took as long as a full flash for my phone to reboot...?).
So I have bought for $1 this nice app called Autostarts that shows which apps autostart, what triggers them to start and it is then possible to disable by app / event.
When I tap on Software Update, I can see that it kicks in on these occasions:
- After Startup
- Application installed
- Application removed
- SMS received
- Secret code entered
I disabled everything as well as for Map, so now it's no longer showing in running apps / processes.
Will follow this thread !

Spot on.
My Android OS battery usage is down to 3-5%.
Great find guys, Thanks a lot!
Also, a little suggestion here but I need someone to confirm.
Regarding Google Maps, I was having some trouble getting rid of Hotpot and Rate Places processes as they were constantly running for no reason and restart after I kill them. Another 13% drain. So yesterday I updated to Maps 5.3 and the processes are no longer there even though I've used Maps, Hotpot and Places

I upgraded with odin, repartition and bootloaders. Since now the battery life is very good, i can see the difference by eyes.

This worked for me.

Doze-Wakelock

Better Battery Stats shows Doze-Wakelock as my worst offender of Kernel wakelocks at 75% with the next offender, power manager service at a measly 13%. I have reset, reflashed, uninstalled, reinstalled, wiped cache, wiped dalvik, yet the wakelock persists and I can not find anything about it on any thread. I currently use greenify, power nap, amplify, and force doze on Stang5.0litre rom. However I have noticed the wakelock on Echoe and stock rom. It persists with Force Doze off (I don't use Greenify's Aggresive doze.) If anyone has any info on this wakelock, please inform me.

I'm also on the Stang rom and i just noticed it after gsam showed my phone being held awake for over an hour during 2 and a half hours of standby. Seemed to start when i turned on the AOD but i can't be sure.

Do you use any if the apps I mentioned above. Ive noticed the wakelock isnt as prominent if the phone is left stationary. So I feel as though it might be greenify or force doze trying to force doze, but android system noticing the motion and not letting it do so, creating a loop and constant conflict. But as I said i can not find anything about this on xda or Google.

Turned the aod off this morning. Definitely the culprit. However noticed 4 random reboots while the phone was inactive. The problem goes away when i turn aod back on. Currently investigating this new problem.

Freezing always on display in titanium Backup after disabling it fixed the random reboot issue. Currently enjoying no doze-wakelock in bbs with a great increase of deep sleep time.

The only one i use is greenify.

Battery Drain | Idle

My Essential PH 1 is draining a lot.
Phone idle is taking most power with approximately 17%. Screenshots attached.
Can you please advise if this is normal and ways to minimize battery drain ?

Are you showing off? because those are amazing numbers. You're on track for 35 hours! I get around 26. Your bigger killer is What's App, but that's expected for a Facebook app. 17% for idle means your phone is on and doing nothing 17% of the time.

Nope I am not showing off, I think i am having huge drains when I am asleep. Most of the time in that graph is idle time so i am thinking it should be better ?
Again I moved recently to droid from iOS so i am unsure of the droid power management baselines.

Cool. I didn't mean to seem mean, but those are good numbers. If your phone is on, and you have push notifications (pretty much every social media app, phone, sms, etc.) you're going to have drain. Even if the phone was off, the battery would drain somewhat. But you have What's App and other chat apps, so that'll use battery, even if your asleep, the phone isn't. It's the only way you would be able to receive calls, text, updates, etc.
That 17% looks steep, but it's all relative to a small screen. over the span of 20 hours and you still have almost 50% battery, especially with "free" apps that are basically advertising engines pushing ads at your every minute. Having Phone Idle at the top is not a bad thing, it just means you don't use your phone as much as you use What's App.

1% per hour is good, better than our S8 even

I had enabled "Cellular data always active" and it chewed through my battery life. I turned it off and can now last 1.5 days on a charge.

My phone is draining 12% overnight. And phone idle is top of the list. What does this phone idle do? There was a random night where the phone only dropped 1%. But most nights, it's draining around 10% with phone idle at the top.
Update: setting wifi to not stay on while phone is sleeping seems to fix the drain issue.

Does disabling it affect receiving messages that rely on mobile data such as WhatsApp?

Where is the "cellular data always active" setting? I don't see it. Have not updated to run Oreo.
My battery was dropping from 95% to 5% overnight. Did a factory reset which helped, but I'm still losing 17-20% overnight. Seems odd to me on a brand new phone, but I have never owned an Android before. I have blocked notifications and location services from nearly all of my apps. Any advice other than what has already been posted?

If your losing that much overnight it's probably a bad app.
I don't use it, but have read that the Facebook messenger is good for that. As in eating up a battery overnight.

I can promise you that that's not normal, especially for this phone. Overnight battery loss is minimal, 15 hours of idle with a 10% drain is what I'm getting. That's pretty amazing. I'd check your apps and ask the general android forums for advice. I also bet there is a rogue app draining you juice. chat and social media apps with all their pushed content and friend updates are huge battery killers.

Install accu battery ,charger to full last thing at night ,don't touch through night ,then see what's draining battery ,mine drains by about 2/3% through 8/9 hrs at night

It's under developer options settings. I have mine always active without draining my battery noticeable.
The social media apps such as snapchat, facebook, twitter, etc... are the ones draining your battery while your phone is idle so you need to disable their background data running.

The option to Cellular Data Always Active is on the Developer Hidden Menu. If you have it enabled you should be able to turn it off.

Thanks to all for the replies. I thought that restoring factory settings had helped somewhat, but it turns out not to have. Battery has just depleted from 100% to 67% in 3 hours while the phone has sat idle.
The only social media apps I have installed are FB and Whatapp. Notifications for both are turned off. Location services for all apps are also off. The only apps I have installed have been download from the Play Store and have run on my previous phones without causing any trouble. Those who replied all suspect a bad app, so I have installed ACCU Battery as suggested to see if I can nail it down.
Thanks again for the responses.

Try this for one night. Right before bed....
1. Turn OFF WiFi
2. Reboot phone
3. Leave WiFi off after reboot
There is a bug in Google Play Services that affects many people on many different phone types since the November updates.
When on wifi, in certain circumstances (many theories on what the actually trigger is) it will cause Google Play Services to run non stop on certain WiFi networks causing huge battery drain.
In this particular scenario, turning off Wifi does not stop the battery drain. The phone has to be reboot.
I don't know if that is what you are experiencing, as you didn't say if it was an app or system taking so much battery, but I thought I would mention it in case it helps.

Why don't you look in settings/battery and see what is using the highest percentage of the battery?

Have looked in Settings/Battery, but am not seeing anything there that diagnoses the problem to my understanding. Highest use shown is Chrome (4%), then Screen (4%) then Google Play services (3%). ACCU Battery app shows the same. Battery is still losing 10-12% of its charge per hour while the phone is idle.
Have sent a message to Essential support to ask if they know anything about a bug in Google Play services causing battery drain. They have so far only suggested rebooting to safe mode and doing the reset to factory settings. Hasn't helped.
Will try shutting wifi off, rebooting and leaving wifi off tonight as suggested. Not really sure where to go from there even if that does save the battery, as a phone that has its battery drained just by being on wifi is useless to me.

If turning off WiFi and rebooting helps reduce system cpu usage, it is a bug in the software and not the phone. I can reproduce that specific issue on my pixel 2 and Samsung Galaxy s8, too....
If the CPU usage isn't from system, though, or turning WiFi off and rebooting doesn't help then you obviously have a completely different issue and need to troubleshoot further.
Sent from my Pixel 2 using Tapatalk

Update:. Nothing Essential support has suggested has helped. Battery is draining to zero overnight while phone is idle both when connected to wifi and when not.
Upon learning that I had purchased the phone at a Telus store in Canada, Essential have said that they can't help me further and have referred me to the store for assistance. I'm disappointed in the lack of support from Essential.

Battery Drain Help

Hey Folks loving my LG V20 so far. But recently, I have seen Android OS, Phone Idle, and Android System draining half the battery life.
I am un rooted, and do not wish to root it as all features I have are there.
Any tips you can provide me? Thanks.

Have you rebooted it firstly?

Have you tried a more in depth battery stats app?
Accubattery, gsam betterbatterystats come to mind
Mine does that in response to installing any new kind of all that scans for media in background. It'll get stuck alot but usually a reboot helps so not sure

Sorry for late reply, I checked my battery health estimate with Accubattery, it shows 94%.
Also, Phone Idle drain is higher then Screen? Anyone else get that?

I have phone idle using as much power as screen use. Sometimes even more.
Not sure what phome idle means. Wifi, 4g idle are included in this?

WhatsApp still draining battery (Exynos)

Even after the april update whatsapp is draining a lot of battery - other than that everything is fine. I'm getting a 8% drain after 1h and 50min of usage. I've seen other S10+, with Exynos, draining the same 8% but over a period of 5h of usage. Anybody else experiencing this issue? I've tried to put the app to sleep, tried to uncheck the "allow background data" option, cleared data and cache but with no luck.

The drainage for you is it happening on LTE or wifi?

Both, I think. It happens when I'm on wifi and when I'm out using 4G - but I honestly didn't do a wifi or LTE-only test, but will do it today.

Look at this. I'm sure this isn't normal.

definitely not normal. try reset app data or cache
Sent from my SM-G975F using Tapatalk

I have the Exynos version and I never had draining problems with WhatsApp.

Ok, I did reset the app data and cache. I'll only use wifi this afternoon. Tonight I'll try LTE-only.

Cleared cache and data but nothing changed

can you install nice catch from good lock and monitor everything
Sent from my SM-G975F using Tapatalk

Yeah, will do it now. I'll be back soon.

Ok, so I've been using nice catch for over 2 hours and nothing strange showed up. Only toast and screen wakeup have recorded statistics - removing my charger and pressing button woke up my phone, and browsing/whatsapp added statistics to toast history - I've deleted a few messages, changed wallpaper on whatsapp and opened a few links in my browser.
Will update tomorrow but looks like there's nothing wrong here.

So, yes. My phone did not wake up - only when I pressed the turn on/off button to check the clock a few times throughout the night.

If you're logged in to WhatsApp Web, try logging out and see if that helps

are you running on freeform?

Can you guys please post your whatsapp battery usage, please, so I can compare? But that amount, like 30% or more (SO and system apps excluded) certainly is too much.

Damn

This is my today's screenshot:

1hr 38mins usage and 14% doesn’t seem like something weird.

Did you find a fix?

What you can tell about this though? Draining 1% each 5min or less..
