Hi,
On marshmallow and nougat with no user apps installed, ie 'factory reset' I have noticed I sometimes get excellent battery, eg I lose pretty much just 2% in an 8 hour period.
However sometimes it is 2% per hour.
It is not an app causing this, no wakelocks that I can see. It seems like maybe a certain sensor gets 'stuck on' and keeps draining the battery.
It happens when not in aeroplane mode as well but is less noticeable as the battery is drained by normal use then as well.
At first I thought it was maybe google play services body sensor permissions causing it but I removed permissions and the drain still happened.
Anyone else noticed this.
I'm a bit OCD about battery, on my moto g 1st gen I only lost 1% max overnight in aeroplane mode so 2% per hour cannot be right.
Scott
FWIW, I was at 100% before bed last night so left mine in aeroplane mode overnight.
Was at 96% nine hours later. I was very pleased with that.
Thanks for the reply. I returned my phone and got a new one. Old one drained 2% an hour. The new one drained 1% in 7 hours last night. So I think the old phone was faulty.
Hopefully the new one doesn't develop the same fault.
Scott
Looks like my new phone has the fault as well. Something causes the phone to use 2% per hour over and above normal use. Probably a sensor stuck on and using power.
I will return this phone as well and give up on Wileyfox.

I recently exchanged a new 3vo after having some dust issues under the screen. This new one is pretty good with keeping dust out but there is a problem with draining the battery even when it's a sleep.
It's been off the charger for about 3 hours after hitting 100% and it's down to 92% after sending a few texts and sleeping throughout most of the 3 hours.
I'm getting worried there's something draining the battery, or if the unit itself is having issues going into sleep mode.

Did you check your uptime/awake time? I usually get 18+ hours of light to moderate use of my phone, I mean, there isnt much to do with the phone because I cant flash stuff yet. I have had two instances, which were odd. I put the phone on nightstand at 100% and after 6 hours my phone completely drained and shut down. Had this happen twice. Cant reproduce it, but I'm sure it'll happen again.
Yeah I checked my awake time and then let it sleep for about a minute. It took about 20-30 seconds to fully stop the awake time after the minute passed. There was an instance where it seemed to not sleep at all.
I don't know if it's supposed to do that.
Hmm...well, this is the second time that this has happened in the 2.5 weeks that I've owned this phone. I'm currently running unNamed ROM 1.2.0 and noticed that my battery is draining quicker than usual (8%-10% drain per hour on IDLE).
Usually, my battery drain is between 1% - 2% per hour on unNamed. What I've noticed in both the instances where my battery drains rapidly is that I end up seeing 'Core Apps' (white envelope with android icon in the middle) under the Battery Usage. From what I can recall about this icon, it's the icon for the launcher. CPUSpy shows my phone at 78% deep sleep (the phone's usually around 93% - 95% deep sleep when in idle).
The first time this happened, I was away from home on business for 1 night and ended up having to power my phone off when it got down to 11%. Got home later that day and recharged my battery while the phone was off and after the phone was 100% charged, it lasted 38 hours with 7% left before I powered off and recharged. Again, the battery with light usage lasted 30 hours with 30% left.
Today, after charging (while off - seems to charge better this way) I was surprised to see that my battery was draining at ~10% per hour and I saw that 'Core Apps' was listed under Battery Usage again.
Fortunately, I am not away on business this time (yeah, my spare charger is on the way) so I can recharge teh phone at home. Is the only way to "reset" the phone's battery usage history by pulling the battery or charging the phone?
Hopefully, one of the devs can answer or provide a fix/workaround for the 'Core Apps' drain? (BTW, I leave my WiFi on all the time and my phone still lasts anywhere between 28 hours to 40 hours...just wondering why I have these sporadic glitches when the battery doesn't seem to last long.)
From my experience... this will be very hard to fix. Usually appear ramdomly, and disappear randomly.

Yeah...the 1st time it happened, I was wondering "WTF is 'Core Apps'?"
Now that I've seen this the 2nd time, I'm stumped by it since you're right...it doesn't happen often and doesn't seem to be reproducible by any consistent method.
Hard to do a battery pull with this Neo Hybrid case (case is a PITA to remove) and I don't have my 2ndary charger yet...
Rebooting the phone does nothing since the battery history remains and even powering off for an hour and then powering the phone back on still doesn't clear out the battery history so the drain continues!
Oh well...it is what it is then I guess...I was hoping that someone smarter than I could find a way to cure this. (BetterBatteryStats doesn't show this as a wakelock (partial or full)...CPUSpy just that my deep sleep state is in the mid to upper 70% which isn't the norm.
Oh well, hopefully, this doesn't happen too often.

But a few have reported their phone doesn't behave right in reporting battery percentages after wiping battery stats.
Doesn't mean you can't. But no one has proven it helps.

I haven't had any issues that can't be directly linked to something else (like random reboots).
If all you want to do is reset your battery useage screen to zero it definitely does that. The point isn't to help anything, just to reset the screen to zero without having to wait for the phone to charge all the way.
In that case not a bad idea if you see it show up. If it's as bad of a battery drainer as it seems and still running, it should show up again pretty quick after you clear battery stats.
It'd be useful in reading the logs to know that at a certain time it was for sure running.

Dunno, it's just odd...recharged my phone last night and now I'm back to 1%-2% battery drain on idle and the phone's going back into deep sleep at 93% and I haven't touched any of my settings. I just let the phone dip to 19% and powered off and put it on the charger for ~4 hours (I know, I could've pulled it sooner since it wasn't at 0% but honestly, I forgot.)
It's just the weirdest thing...whenever Core Apps appears as the envelope w/Android icon it seems to be persistent and stays in the battery usage. However, there have been times when the Core Apps appears as teh same icon as 'Contacts' and will disappear on it's own after a while. <-- This seems to be okay as the battery drain remains minimal.
I'll have to check out Entropy's battery drain thread later to see if I can gain any insights. (Haven't ever flashed any of Entropy's kernels as standalones -- I've just been flashing unNamed ROM so I know the kernels are stable builds and not the experimentals.)
Before flashing CM9 to my mopho I had only used the stock rom, on Gingerbread my battery would last for 1.5 or 2 days, but since i updated to ICS it dies whitin 10~ hours of idle...
it usually goes from 100 to 70% overnight (6 hours). Recently I purchased Juice Defender Ultimate hoping it would help fix this issue, well... it did help but id didnt solve it, went from 30% overnight battery drain to 15-20% with airplane mode enabled in JDUltimate.. wich is ALOT from what i've read most users are getting (1-2% overnight, am i right?).
I've wiped my battery stats over and over (even tried the market app method) and nothing has changed.
I installed BetterBatteryStats and Watchdog from market, and both of them and the android battery stats show that "suspend" or phone idle are the cause of my battery dying so fast.
If anyone experienced anything similar and knows a way to fix this I would really appreciate it!!
Ive never seen my Photon go overnight with only a literally 1-2 percentage loss.. Not on stock, Cybiks CM7, or on CM9. but it usually only drains maybe 10 or 15 percent on higher end so nothing major. Talking ~8 hours off charger idle with random text or two and led going nuts blinking all night with data/wifi/bluetooth etc off but NOT in airplane mode. Are you on latest CM9 build? My bet is you have a random app screwing with phone keeping it from entering sleep mode or whatever its called. Check the "Awake" time under the battery settings to see if the awake time is allot higher than the "Screen off".
I have the same problem, no matter what kernel, no matter what cm9 build, still draining too much in idle. I know, others don't have such draining. But I give up and I am back on cm7, where everything seems fine.
I noticed that this happens to me as well. Previously, I fixed this by re-calibrating the battery. Now I was suspecting skype, but it is not causing this. I have noticed that having both GPRS/3G enabled and Wi-Fi drains power very quickly (about 4 times faster than having only one of those switched on). I'm using Photon in Europe in GSM network, so not sure is it the same with CDMA.

during night, "Awake" seems to be up about 50-60% of the time, a lot more than "screen on"
I´ve read that setting your phone to "never turn screen off" shuts down suspend process and battery actually lasts longer, has anybody tried this??
Are you guys logged into Latitude? I signed out of it yesterday and now after 10 hours on battery, although 6 of it was sleeping, I still had 86% left.

Thanks, I logged out already will report back after some time
I am not sure, but never logged in latitude myself, so I think, no.
And CPU was perfectly sleeping with turned off screen. But still the same draining. And what I know, it has nothing with gsm.
I as well am having the same problem, dropped from 88% to 72% within 20 minutes.
phone idles killing my battery at 50% any fixes?
try wiping battery stats in recovery with a full charge
hi guys , i got some problem with the information displayed for my razr maxx. the thing is the battery usage curve won't change for the first 10% of power drain, and the awake bar and screen on bar are full. but when the battery drops to 80% and below, the curve starts to count from the 80% position, what is going on? how can i fix it ?
here is the screenshot
How many times have you already charged that battery from 0% to 100% and drained it back again to 0%?
Seems like a simple calibration issue that should have no effect in real world battery performance.
Had that too. If you want to know more about this, look up "batterystats.bin".
So, if you haven't done what I said in the first line, do it and report back.
i have tried delete the .bin file bwfore, nothing changed. i think i will try to charge it from 0to 100again see if there will be any change. btw will the battery calibration apps solve this?
http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
Read that. You don't have to do anything, just let your razr get some charge cycles and the readouts will be right. Remember: There is no need to tinker with this, as this has no effect except for cosmetic terms.
thanks for the information. one more thing, the battery indicator always shows that the screen on and awake time are the same, even after i turn off the screen and play music for an hour. is this normal? or the system keeps recognizing the status of the screen as on? how should i deal with this?
I would just wait a few days (read: charge cycles) and look again. Indeed strange, but if your battery doesn't get drained this also seems just to be another cosmetic issue.
actually it seems it has been more energy draining than before. it wouldn't drop 1% when i turned on flight mode at night and checked it in the morning. but now even i turn on flight mode it drops about 5% next morning.

Don't count on the battery percentage today. Look again tomorrow/after some charge cycles.
The battery readouts need to be calibrated to display the correct battery level.
I had the same "issues" (in fact, those don't seem to be real issues) and they went away. I assume your razr will behave the same as mine
Is the phone still new? I know mine was a little wonky until the charging and the meter apparently calibrated themselves to Maxx's battery Ever since, it's been very accurate.
yes it is still new. i got it about half a month ago. just got it charged to 100% from 0%. gonna see what will happen。
I have an Atrix 4G running Neutrino 2.9 EE, with a new battery I bought only a few weeks ago because I thought my old battery was dying. But I'm having the same problem with this one. I can't get it to charge past 70% or so, and the charge seems to drain very quickly, about 1% every 15-20 minutes. I checked the battery usage, and Phone Idle is taking up around 60-70%. I've got wifi off, the screen turns off after one minute, and the brightness on half. I'm really at a loss as to what's causing this, so any help would be great.

Try to use all battery till your phone turn off, when charging again go to recovery and clean battery stats, rebbot and charge to full battery, see if your bar go to %100, i install battery widget and have an option for motorola phones, enable that option, that help me a lot,
Good luck!!!:fingers-crossed:

Battery drain issues, it seems, are as varied as "My car is making a noise that goes like this: ____"
Do you have the battery calibration app off the market? A full charge is 4200 mV (or really close to that value), regardless of what percentage your phone is displaying.
If your phone is getting up above 4100 mV, then the battery is fine. You can trick the phone back into displaying a more accurate percentage for a while, but it's not permanent:
- Charge the phone as high as it will go
- Shut the thing off and pull the battery
- Plug in the phone, wait for the question-mark icon to appear
- Re-insert the battery, let it sit for a few minutes (10? 20? no magical number here)
- Turn the phone back on. Percentage should be a lot closer to 100%.
If you're getting a decent charge but the battery is genuinely draining quickly, well... all I can offer is my experience from this summer. My major symptoms were:
- Losing an entire charge in the course of 8-9 hours, but ONLY when wifi/mobile data were turned on
- *Extreme* phone lag when wifi/mobile data turned on. Every single app would force close. Not fun at all.
- Checked what's using the battery, and "Contacts" was responsible for ~5% of the charge.
After six weeks of debugging hell, wiping, reflashing stock, etc I found out my contacts were nonstop-syncing (and duplicating, and duplicating, like rabbit offspring) on one particular email account. Killed the email account, got a functional phone back. Battery life returned to normal. All that to say, one misbehaving app (even a stock misbehaving app) can trash the phone's performance.
If you can stand it, try returning to something completely stock and not restoring any of your apps/data for a few days.
