G'day,
I've had some odd issues with two consecutive Xiaomi phones, and I'm hoping someone here can shed some light on it for me.
With both my Mi Note 2, and now my current Mi Mix 3, after less than a year of owning each one (respectively), out of nowhere, the battery life drops through the floor, the phone gets really hot, and most oddly, I got wicked battery drop while the phone is off (e.g. I turned the phone completely off at 77%, and about an hour later, I turn the phone back on and it's at 43%).
On both phones, I've tried a factory reset, but it didn't work. It was, for all intents and purposes, fecked. At the moment, I'm waiting for the 15 day countdown for my Mi Mix 3 bootloader to be unlocked so I can try flashing the EU MiUI ROM and see if that helps, but that's still a hell of a long time to wait with a phone that idles at 50+° C and has a battery life of about 3 hours with minimal SoT.
I've installed BetterBatteryStats (using ADB to provide permissions), CPU-Z, CPU Monitor and Ampere to see if I could get some more information. I found a few things:
1. Somehow, with mobile data and WiFi enabled, the system was drawing SO MUCH power (reported by Ampere) that it literally wouldn't charge while plugged into a 2A wall port. It was drawing like 1300mA when it wasn't plugged in, and when it was, it was STILL drawing about 130mA, meaning no matter what, while the phone was on, I was losing battery.
2. BBS reported the biggest battery killer was under the 'Alarms' tab, caused by Android, which were "Intent: *job.delay*" and "Intent: *job.deadline*". I have literally no idea what these are, what's causing them, or how to stop it triggering.
3. I've done a full factory reset. The first hint that something was wrong was when I noticed that the phone wasn't charging when it was plugged in and turned on. I did the full factory reset, didn't help.
I'm currently running Global MiUI 11.0.4.0, Android 9.
Does anyone have any ideas? I haven't manually updated anything, I'm not particularly rough with the phone, but for two phones in a row, this has come straight out of nowhere. It's a shame, because the Mi Mix 3 has spoiled me with it's 100% screen real estate (no hole-punch, no teardrop for front camera), but I think my next phone is gonna go with something else.
Cheers.
Update: I've taken a squizz at the Google Battery Historian and basically, I have no feckin' idea.
The best I can get out of it is "Yep, something in the labyrinthine generic 'Android' system is causing it, but good luck narrowing it down or stopping it."
That being said, I've found that this Partial Wakelock is triggered fairly often (1-6 times per minute, give or take): IntentOp:.common.broadcast.BackgroundBroadcastReceiverSupport$GmsReceiverIntentOperation
I have no idea what the hell it is or does, and the only information I can find about it is from developers asking questions where it just happens to be part of their codebase, or a breakdown of how the WakeBlock app works.
It's getting woken up about every minute or so (usually more than once a minute). However, the wakelocks appear to be part of the core Google/Android systems that can't be individually disabled.
I'm still feckin' confused.

Any ideas as to how I'd further troubleshoot? I've gone into *#*#4636#*#* and changed the sort of signal it looks for, but it doesn't appear to have fixed anything.
In case anyone is interested, I've attached on of my Bugreports (from running adb bugreport), which can be viewed through Google Battery Historian.
I'm not saying there's a cash prize for anyone who can tell me what is happening and why, but I'm also not saying that there isn't.
So, I think we have our culprit (maybe).
I have attached several screenshots from a Battery Historian I took after having my phone on all day. The total phone on time was about 4-5 hours with, no joke, maybe 10 seconds of screen on time. Let's go through this absolute bullshittery together, shall we?
Battery - Full Time: The full length of time captured by the Battery Historian/bugreport command. It's in Zulu Time (GMT+0) and I'm in Australia (GMT+10), so the line starts going up at 5PM last night, which is more or less when I plugged it in to charge. You can see, while 'off', it took 16 hours to charge to 100%, and this was from a 'cold boot' (phone is completely dead), so it didn't have any information about what had been running, etc.
Battery - Discharge: The five or so hours time in which the entire battery discharged, starting from when I woke up in the morning and got ready for work. In the Screen row, you can see the small, three-to-four second windows throughout the day that I turned the phone on to check the battery. For almost the entirety of the time, the screen was off. You can see where the line next to Phone State goes from black to navy blue. This indicates that the phone has been put into Airplane Mode - you can see this is also where everything relating to network connectivity or mobile strength completely disappears. You can also see that App Processor Wakeup completely dies here - that means that actual installed apps (including GOOGLE_SERVICES and Xiaomi's preinstalled Facebook app stop sending commands to wake the CPU.
Battery - Cause: At least once a minute, usually more, two things fire that keep the CPU running - Abort:Wakeup IRQ detected during suspend: 999 msoc-delta and Abort:Wakeup IRQ detected during suspend: 663 qpnp_rtc_alarm. I have no feckin' idea what either of those are, and Googling results in either developer guides or threads that lead nowhere. If anyone knows what they are, for the love of God let me know.
Battery - Foreground Processes: While the phone was off, with every app closed, in Airplane Mode, we can see that there are still four apps that are somehow in the foreground: com.miui.mishare.connectivity (odd, since there's no connection), com.miui.securitycenter (which I tried disabling through ADB last night, and it stopped my phone from booting. Oops), com.miui.notification, and com.android.providers.contacts (which disappeared shortly after entering Airplane Mode).
Battery - Video: You can see here, for the ENTIRETY of the time that the phone was turned on, this odd Video row was enabled. There is no other information about it - what causes it, where it's coming from, what 'Video' means, anything.
Battery - 7 Second Slice: This is just a close-up of a seven-second period of time, wherein the above 999 msoc-delta and 663 qpnp_rtc_alarm kept the CPU running six times within 7 seconds. Not a lot on its own, perhaps, but over the course of hours, it clearly causes issues.
I've also attached the latest bugreport where I took these screenshots from if anyone wants to try and make sense of it.

This looks to me like an hardware issue more than anything, what is the idle state of the cpu?

Same problem. Any solution?

Hoping someone might be able to help me here..
Within an hour of being taking off the charger (and confirming it was 100% at that time) my battery life is down to 80%.
What's happened so far is:
1) alarm went off (set to ring only - no vibrate)
2) recieved 2 emails on yahoo (set to check every 60 mins)
3) received 1 push email through exchange/active sync
4) 1 calendar appt reminder.
The screen has probably only come on 3 times for no more than 10 seconds each time. My brightness is set to the 2nd lowest level possible. My ringer is on the highest.
Here are the apps I have installed. I have not "launched" any of these today.

Microsoft My Phone - (set to sync once at 3am & was on charger then)
Mobil manager for netflix

Phone is about 4 weeks old.
download HD Tweak and set up data disconnect after to 1 minute. I am almost positive your data is staying on after downloading email because i had the same problem with my Touch Pro. Keeping the data session open is a huge battery drain
My battery life is terrible too! I charge it fully throughout the night and the phone typically dies by the time I get home from work at 6PM or so. I barely use it at work. Never talk on it. The occasional text message. But by the end of the day the phones dead. I have no idea why. I know for some odd reason by phone will not automatically go into sleep mode. It should, but doesn't. Not sure if that kills the battery even though I manually push the sleep mode button each time.
I set up the HD Tweak software. We'll see if this helps. Does it work for the Touch Pro 2 also?
Any of you guys using a case with a magnet on it by any chance?
Possible explanation...

Just curious, did you charge the phone while it was on? If so, I've found it a problem. I once charged my phone while it was on, and I took it off after about 2 hours (the green LED indicator probably showed up an hour before I took it off). I checked the battery meter and it registered at 89%! I found out that there's a flaw in the way the found charges. Once the LED turns green for a full charge, the charger cuts off, but (I think what I'm about to say might be true) the phone thinks it's running something as it charges, thus causing the rapid battery drop.
Since then, I stopped charging my phone while it was on. I now turn off the phone and then charge it. I can last a whole day with about 45 minutes total on the Internet, and my battery would go to about 60+%.
However, as jaas666 pointed out, are you putting your phone near a magnet? The magnet tricks the phone into thinking the stylus/keyboard is being pulled out, thus causing it to wake up, which will drain your battery.
Have you tried a task manager to see if a program is running when it's not supposed to?
http://www.dotfred.net/TaskMgr.htm
I had terrible battery life and found two issues. One program was always taking up around 10% CPU usage (VZO video chat software). Also found that Google Sync, set up through ActiveSync, was having trouble. I'd open ActiveSync and find it in a synching loop. For me the solution was to untick "Tasks" in the sync menu. Since then, battery life has been great.

HD Tweak works fine on mine, I've also heard of some people using Diamond Tweak. I mostly text all day maybe some internet but I have gone a day and a half without charging and even then my battery had only gotten to ~20% so I think with a few changes it could be fixed. I'd check out some of the Tweaks threads here and at PPCgeeks for registry edits u can do to save the battery too
I had those issues with my 2000mAh battery on my sprint tp1. With my verizon tp2 my battery life is fantastic. I use the crap out of it all day also. Was wondering if the bad battery life is happening mostly with sprint users.
I have my active sync connected at all times for wireless email calendar task syncing. I charge with the phone on all nite long and the battery drains only slowly throughout the day. Less than 50% today. It is on 24/7 I never shut it down unless I'm soft resetting due to a file or app install. I use my ms3.5 task manager to keep stuff closed after using. I always put it to sleep mode by the button when I'm done with it. My screen is set to brightest and stays on 2 min. before sleep mode engages unless I manually do it.
I'm sorry to hear your battery issues, my tp1 with sprint was really hard on battery juice. I found it would struggle to find a signal alot, one reason I switched to vzw.
Hope you figure it out.
Sad to say that my less than 4 days old Sprint TP2 is disappointing to say the least in battery life and all around usability. Now i'm coming from a Treo Pro and so used to one handed operations and such. But i digress...
Battery life on this beast is sad, really sad. Someone alluded to Gmail Exchange ActiveSync as a potential battery drain so i might look into that. Basically i'm gonna hard rest and start from scratch applying less tweaks. Basically i find TF3D tedious really..takes too many steps just to do some basic things. I turned it off and managed better a bit but i just might go back to my Treo Pro and sell this thing..
My battery "appears" to drop quickly, but actually hangs in there quite nicely. My old phone only showed me 20% increments, so going to 1% makes it very noticable.
I ran cleanup first thing, then went back and customized.
I use Activesync in push mode (7 days per week 8am - 9pm), have it checking Hotmail, stocks, weather every 30 minutes. BT is on, Data on, WiFi off. I even went back and turned auto screen back on as I couldn't read cleanups default change in the sunlight.
Gets turned on at 7am, and at 10 pm I'm ussually 30-40%. Medium user - 40 minutes phone use daily, 1-2 hours total IE time, ALOT of email checking, hardly any SMS.
I do use a magnetic holster too. S2U2 fixed that issue.
Biggest drain I noticed is screen. If I turn off auto and go back to CleanUp default, I can get through almost 2 full days if I turn it off around 11pm, and back on 7am.
And as far as battery total use, my older phones always turned themselves off at about 15%. THIS THING WARNS ME AT ABOUT 4% and turns off 2-3%! That's alot of extra battery use.
There is a company making a 1750a battery that will fit in stock case.

Hey guys,
N00b here.
I've read the n00b guide and also searched around in the forum. I did find a thread similar to mine however I couldn't really get any useful info out of it and maybe since then new tools are available to help me track my problem, so I post my question.
So... on to it...
My Nexus S is suddenly having high keep-awake times. About phone tells me a battery usage of 32% android system, followed by 21% Display. Android system has a keep awake time of 3h 51m and a CPU total of 7m 52s. All this over the course of 19 hours. I don't have a screenshot with me but it's clear that the phone is awake a lot when the screen is off.
Automatic updates are off.
Some days ago everything was fine. My google acount is only synching contacts and calendar and even that is turned off when I'm not at home. Even so, I saw a high usage of the keep-awake bar even when the screen was off.
I've installed some weather widgets and battery info widgets and the update cycles of weather applications are around 45 mins so I wouldn't see a reason for such a high period of keep-awake cycles.
Anyway, each phone is a phone, is there an application that can tell you what is keeping the phone awake ? I have installed Watchdog lite but it doesn't show anything abnormal. I've installed Spare Parts Plus but it can't show me the battery usage history because apparently stock 2.3.4 Gingerbread doesn't support it.
So now I'm stick with trying to disabled notifications on one app, remove its widget and see if it helps. If it doesn't.. go to the next. This is quite tedious work really.
Still the battery life is ok I guess... 50% after 19 hours however I haven't played around with it much but I would be happier to have a low keep-awake cycle for the Android System like I had some days ago.. makes me feel like everything is fine
Thanks for any hints guys!
Having the same issue as well.. I have my widgets and such to only check every 4-6 hours, but the awake time in the battery stats is nearly on all the time.
Keep awake time is 4 hours and 22 min, out of 12 hours of battery. I'm left with 42 % battery with only 1 hr 15 min on screen time (texts and such, no games).
Hmmm a memory drain of 60% in 1 hour is quite a bit heavy. I would suggest you to download Watchdog lite from the app store and use it's real time CPU analyzer to try and see what's consuming the most.
Once I had weatherbug going rogue. But then it showed up in the battery usage list with a high CPU usage and clicking on the item I could see a high awake time so I uninstalled it.
At the moment I've removed some of my widgets and so far it seems to be OK. However tonight I had some weird awake times again. I uninstalled Battery Info widget from the phone and I'll see if it all goes well tonight. Then I'll start to activate the other widgets I had deactivated before to see what happens.
Also I downloaded aCatLog from the app store. Pretty interesting tool... you can see what's going on in the logs. I see a few Java exceptions every now and then.. never a good sign as they might not be handled properly by the application code that threw them. I see evernote synch problems, a data traffic counter throwing exceptions and K-9 to have problems with idle connection reset by peer. And I often see the garbage collector working. But I assume all this is normal. Switching to the event log it's too much information to absorve. Nevertheless I haven't seen in any of those logs an explicit request or grant of a system wake lock.

Do I need to download Terminal Emulator from the market to do this ? Or do I need to download the Android SDK and connect to the device via USB ? I need to check out to do this, never done it before and this is my first android phone.. only a week old
Again this morning my awake time was on for quite a bit (I guess 1 hour). I got an extract of the main log...
Some things are curious, the following occurs more or less each half hour. I am signed out of gtalk why was the service trying to keep alive ?

And that's all I could see. Everything else seems to be garbage collection WiFi activities and what not..
It seems that I've narrowed down Go Weather as what's making my Android System stay awake. I couldn't see anything really useful on logcat about this but empiric observations seem to confirm it.
If I remove the Go Weather widget and turn off it's background updates (hourly), then restart the phone... I see the Android System incrementing some 3-4 mins keep awake time per hour. If I set the widget again and turn on Go Weather's background updates, after an hour the Android System keep awake time goes up like 15-20 mins or so. If at this point I remove the Go Weather widget and turn off it's background updates, the Android System keep awake will still go up at the same rate as if the Widget was there. If I restart the phone without the widget, then the Android System keep awake seems to increase back to regular 3-4 mins per hour.
The funny thing is that according to Permission Dog, Go Weather doesn't even use the WAKE permission so I would rule it out as what was keeping Android System awake.
Android System was driving me crazy too. I figured out that when my WiFi was enabled, it would continually keep the phone awake when the screen was off. So I just toggle the wifi off when I'm not using it, and android system behaves now.
I'm curious as to what changed though, because when I was using stock 2.3.4 and CM7.0.3 I would leave wifi on all day, and android system didn't cause any battery issues.
Hi,
First post here, so I hope I'm posting at the right place.
Just bought an unlocked Samsung Omnia W (Focus Flash stateside) around four days ago. I didn't notice anything about the battery life the first two days since I was using it quite heavily and felt the rapid discharge was normal (the usual rigmarole- everything turned on).
Last two days, I've started using services more selectively, and still see my battery discharging at an alarming rate. I'm talking 5-8% in an hour with barely a minute or so of the screen being on for checking texts and sending a few.
I've disabled everything- location services, ALL live tiles, WiFi, Bluetooth, even went as far as to disable 3G and switched to 2G. I switched back to 3G because where I'm at I get a full 3G signal but a very light 2G signal. I've put off all background services (Gmapps was the only one, I uninstalled it). Turned off Xbox Live connection as well. Turned off facebook chat. Removed the People Tile. Three email accounts set to sync "as mail arrives".
I noticed the battery saver screen was showing me only 3 hours on 48% charge. I then completely discharged the battery through WPBench battery test (which showed 52 minutes starting at 25% battery life). Now, I've been charging it for an hour or so, and the battery saver screen shows 22% and estimates only 1 hour as the run time.
Is my battery defective? The WPBench time of 52 minutes for 25% seemed par for the Focus Flash (Engadget gave it a run time of 3 hours 30 on WP bench I think), but this fast discharge is really baffling and makes me kind of afraid to use the phone too much. I've heard the Flash has stellar battery life, so if anyone can throw some light on the matter, that would be great.
By the way, updated to 8107 two days ago through Zune. Normal usage consists of 30-40 texts a day, an hour of calls max and maybe 10-15 minutes of browsing. Battery saver screen usually shows only 9-10 hours on a full charge, though it does last a bit longer than that (14-16 hours). I'm sure such light usage doesn't warrant such a quick discharge.
I apologize if this makes for a really long read, first time here.
Thanks.
First, battery saver gives times based on previous data so it will get more accurate with time. Second, the battery will get better after about of week of use, it takes a little time to 'break in.' Third, if you are in an area that has poor reception your phone will try to find a signal a lot more and this can drain power quite a bit. Fourth, try returning everything to normal as far as background agents, email sync, and data settings ect. but turn 'battery saver' on after a full charge. If you still have bad battery life then perhaps somethng is wrong with your battery/phone.
EDIT: if you are using 'light' as your theme you will use a lot more power since amoled screens work best with black bacgrounds since the black areas are essentally 'off'
Been using a dark tile. Let's see how it handles with time.
A lot of my friends with Android phones simply keep data off since their batteries barely last if it's on, do I need to take any such harsh measures with WP? I hope not, I like my mail to arrive immediately (I have set sync on "as mail arrives").
Push email (the "as mail arrives" setting) is actually a very substantial power-drain. Setting it to even just every few minutes (5? 15? I forget what the next level down is) will help.
I may be wrong, but won't it cost less battery if the phone was getting push mail, say, three times a day for 3 separate mails as compared to checking every hour 24 times a day?
Why would you think that? The phone doesn't magically know when email is available for it, to only wake up the email sync process and data connection then and leave them off the rest of the time. It has to maintain a continuous (or nearly - often enough that you don't notice the gap) connection to the server. Even idle, any kind of live data connection uses more power than a process which stays suspended 99.9% of the time (meaning 86.4 seconds of activity per day, which is probably a pretty good estimate actually).

I thought push email and other kind of push notifications were sent from the server to the phone, and so the phone didn't have to be constantly checking for email updates...
The phone needs to be listening for those notifications. That requires running the radio (for data) at a higher-than-minimum level. Push notifications have a similar impact to push email, in terms of battery life. It's not hugely destructive - I have two email accounts that use push, and still tend to get through the day and then a bit just fine - but it does impact the battery life.
I just got an LG V20 which is good on battery when in use but sucks when not in use. The culprit is always wifi. I just discovered the root cause is Location services that is using wifi to get locations even when wifi is off.
To stop this, go to settings->location->scanning.
Uncheck wifi scanning. For good measure, uncheck bluetooth scanning.
Go to wifi menu ->advanced-> keep wifi on when screen is off
Change to never or "only when plugged in"
Hi,
thanks for your helpful tips..
So out of the 3 tips you have:
1. Uncheck wifi scanning
2. Uncheck bluetooth scanning
3. Turn wifi off when screen is off
Any idea how much does each option save (if you've quantified)?
I'm happy to follow points 1 and 2. I'd only do 3 if it really helps a lot, because most apps would use data if wifi isn't available to periodically phone home.
I have always been dissappointed with my V20 standby time.. I had all of these settings on.. so i'll see how she does now they are off.
Thanks!
My standby time is from 0-4% over 8-9hrs. I really cant complain.... but the phone is facing down.
I wasn't aware of the wifi location scanning, and the bluetooth scanning. Giving it a try as my standby time has been horrible lately.
I am also facing severe battery drain on my LG V20. Battery easily drains by 5-10% per hour even when the phone is lying idle with screen off. Major culprits are 'Phone Idle', 'Android System' and 'Android OS'.

As a side note, I've found that using wifi and cell data to help location services causes maps to scan these options and slow down (maps keeps saying every 5 to 15 seconds "searching"). By using gps only, the maps app is faster and less battery drain.
Obviously if you are indoors you need the help of wifi or cell data. But in the car or outside it is unnessary.
Thanks for your tips it's very good for my life battery. :good:

I tried as suggested in the post you shared. Once the Bugreport was generated, I got a notification to click it to share. But, upon clicking nothing happened. I did not get anything (no pop-up, no options) further to share it. I tried thrice but, every time same end result.
How can I access the Bugreports generated on the phone?

Ah, seems like the obvious question but you can't.
I've found the most reliable way is to email them and then download them

- see the cpu running, userspace wakelock & screen on lines. They seem to match. Screen is on, cpu working with userspace wakelock. Close to 7pm the screen is off but the cpu is running, because you were listening to audio. I don't see a problem here. Looks normal
- you screen off discharge rate is 2.56%/h which seems a bit high. If you were streaming audio this might add to it. Do you have the second screen on when the main screen is off ?
- somewhere around 12pm you are using data for about an hour. Mobile Signal strength isn't very good, mostly yellow. What i don't understand is why your wifi is also on ? and this is in an area where wifi signal is bad. Both of these will add to drain. And in two hours your battery dropped from 70 to 40
- little after 1pm you're on wifi for a couple of hours but the signal is weak
- around 5pm you're back on data streaming audio and battery takes a nose dive here. Down 30% in like an hour. Were you moving ?
- then you charge up to 85%, doze kicks in which is good, if there was app drain doze would not come on, for the next 5h without use, you lose about 5%
- the part i don't understand is between 1am & 6am, battery drops 10% yet full doze (blue) is on. So there is some activity going on there. What ? sync ? updates ?
Not sure about the aggregated stats as you've recharged up and run down fr a second cycle so it could be your off screen drain is twice as high because of that
charge up again, go through your day and save log when you're at 5% and lets see the two screenshots from just one charge cycle

Thanks a lot! Please find my answers in sequence.
- I listen to music while going to work. But, that is, till 8:30 AM only. Yes, I have 2nd screen ON when the Main display is OFF.
- I watch stored videos during lunch (12-1pm) for around an hour but it shouldn't be using data as I am playing stored videos.
- Around 5 pm, I leave for home. Again while going home I listen to music for half an hour.
- I have no Idea of what is happening during Night because I just leave it and don't use it until morning. In fact, I have scheduled the 2nd screen to be off between 11 pm and 6 am
I will try to run a proper cycle as you have suggested and will recapture the logs.
I understand the battery dropping while I am using the phone (listening to music/watching videos/browsing/anything else). What I don't get is the battery dropping insanely when I am not using it. For example, once I reach the office, I stop the music, kill the music player and just keep the phone aside. After 1-2 hours, as I check my phone I find battery dropped by 10% or so! It's the battery drain while my phone is just lying idle that is troubling.
Also, I have noticed that once I charge my phone and then leave it (Not using it) the battery drain is minimal like 1% per hour. But, once I run some app (music/browsing etc) for a little while and then leave the phone, the idle battery drain is pretty high.

Same sequence
- When you have the second screen on, is the phone facing up or down. What i notice with that second screen is it ignores any brightness settings. If the phone is face up and pointed at a light, the second screen becomes very bright. If its facing away from the light then it dims. Depending on how your phone faces you will either have more or less drain here, without doing anything and phone just sitting there. Typical overhead with second screen on and normal brightness ie not too bright is around 1% per hour. This could be adding to your off screen drain. Why not try a couple of cycles. One with second screen off and another with second screen on. Just to see how your off screen drain rate is like.
You say you listen to music only upto 8:30AM, take a look at the audio line. Can you see audio triggering ? there's little blips there after 8:30AM which continues till 5:30PM where its solid. This is your ride back where you listen for an hour. The 5:30 audio is ok but the blips in between are not leaving aside lunch video. Each time there is an audio blip there is a wakelock. Pay attention to the duration of the audio blip, if its a few seconds it could just be notification, but if its longer, does it correspond to your use.
Now look at the top app line, try to find which apps are running when audio triggers. To do that hover over the top app line which coincides with audio when you were not listening to audio. You will see a popup screen with a list of apps. Or check History Stats - TopApplicationSummary for a table, screen shot that and post
Do you use a lot of widgets that update in the background ?
- something was using mobile data when you were watching stored videos at lunch. Take a look at the'mobile radio active' line and you see activity there around lunch. Your wifi however is off and not running. If there were any apps running they were using mobile data, this is extra drain
- take a look at the line that says 'foreground process'. it's pretty solid right through both your runs. The only time it stops is when you recharge. This is a hint something is up. If you hover above it what does the popup say ? try moving along the line and observe whether the information changes
There shouldn't a foreground process running when you're not using the phone. Maybe if you can screen shot, the table that displays under History Stats - Foreground Process Summary
Scroll down and under the graph and on the left you will see three headers with twisties, System stats, History stats & App Stats
Hold on to your bug report files and they will be useful to verify if any changes you make take effect or not
- 1% per hour corresponds to second screen on, with it off your drain would be halved. However having drain after leaving a music or browsing app isn't good. It means a wakelock was caused and its not releasing so doze can't kick in. So battery will drain. If the phone is shaking, say in your pocket as you walk around, full doze won't kick in either
Which social media apps do you use.
Stock launcher or other if so which
I've found just buying a new battery off of ebay for $10 is the the easiest way to gain back that extra hour of on screen time and extend stand by. That's why the phone was made with a removable battery. I have 3 of them and don't need to touch a charger for a week. and when the time comes to charge the batteries, just put them in the charging docks and done.
Hi
I've got a brand new PH-1 and haven't yet had time to set it up properly, only started it up, let it update software and used for an hour or so before testing the idle battery drain.
I haven't installed any apps or changed any settings other than to disable the google app (to prevent it listening for or responding to "ok google"). I tried out the 360 camera, signed in to gmail and browsed a few websites, before charging back to full and restarting the phone before this test anyway.
But leaving it idle with the screen off and with phone network disabled (there's not even a SIM inserted), only wifi on with good signal, it lost 65% battery in under 22 hours. Screen on time was less than five minutes.
Is this a hardware issue I should RMA, or is it considered normal? If this is normal and there's no easy fix, I'll probably end up having to return the phone anyway for a refund, because if it can't even last a day and half in idle there's no way it would last a reasonable amount of time with normal usage.
Any ideas?
Thanks
Since there isn't a sim card installed, try going to airplane mode and then turning WIFI on.
I am getting about 1.2% drain with cell network and wifi enabled along with all my standard apps installed.
On a typical day with 1-2h SOT, I usually have 60-70% battery left at midnight. I'd try to reset the phone, and then testing again - occasionally a system update will end up doing something funny
I left it overnight with airplane mode on, so even wifi was off, and it's a little better but not by much. Screen on time was one minute.
With airplane mode on, screen off, no dodgy apps, the phone really shouldn't be doing anything to drain battery.
I'll try a full factory reset and see what happens.
Just to follow up, a full factory reset seems to have fixed the issue. Even after doing the same things I had done before (connected to wifi, updated, logged in to gmail, etc) the battery now drains at a much more sensible rate.
Very strange that a factory reset made a difference since it was new from the factory when I had the issue, but I guess something strange happened in the update like dsip suggested.
Thanks for the help!

That's ? percent normal behavior. Anytime you flash a ROM (new phone =new ROM) you need to wait a bare minimum of a charge cycle (more like three in my experience) before you get the slightest idea what your actual battery drain is going to look like. think of it like breaking in the engine on a new car.
