So I thought I had plugged my OPO into charger before falling asleep last night and it appears that I did not. It died around 3am. I was obviously unable to boot due to low battery and immediately plugged into AC charger. It initially gave warning that battery was too low and to wait to boot until battery got more of a charge. I waited until that message went away and it was showing the battery charging animation. I booted the phone and had the Android L boot animation going, then it got weird. The lock screen didn't have scrambled keys like I had set but still remembered my PIN. Unlocking it looked like a lot of things were set to defaults like the launcher and icons in launcher. 90% of the installed apps did not show up including system apps. It appeared like corruption on the internal storage to be honest but internal storage mounted to /sdcard appeared to be fine with TiBkup able to access all backed up apps and settings as it was one of only 16 apps in the app drawer. Battery showed 1% at this time. I performed a reboot and all apps restored but certain UI and launcher options were still reset to default including missing widgets, ringtones, and SuperSU permissions. So far I have not noticed any additional issues and all accounts appear to be working. I have my OPO with stock CM11s 38R (fastboot flashed/wiped over the weekend) with Boeffla-kernel and SuperSU root. If anyone else has any ideas as to what happened or if I need to dig up some logs, I should be able to do that. I have not rebooted since the second one to get most of my stuff back.
So for the past few weeks my phone has really been acting up. I'll try and make this an organized question/post.
Here's the symptoms:
-Phone drops from 30ish % down to 1%, then powers off and wont turn back on due to low battery.
-Phone occasionally reports fully charged at different levels (such as 80% or 50%), upon reboot, it is listed as 100%.
-Some days I can watch it drop 1% every few seconds once it reaches 35%, literally like it's counting down.
-Other days it just works fine, I can use it to 5% and then charge with no problems.
Phone information:
-Z1 Compact
-Problem persists between ROM flashes and android versions. Have experienced issues on stock 4.4.4, stock 5.0.1, AOSP 4.4.4 and AOSP 5.1.
Really, any sort of help or places to start would be greatly appreciated. I don't even know what to try anymore and I'd really like to avoid trying to replace it (warranty expired already).
Attached a screenshot illustrating it happening. I unplugged my phone last night after charging it to full. Made it to work, put it in airplane mode, turned wifi on. Updated some apps and restarted it. Rebooted to about 10%. Charging again now.
About two months ago my old battery stopped working well and always turned off before reaching 0% so I bought a new battery off amazon and replaced it. Everything was fine. The battery lasted easily for a day and I didn't notice any problems. But yesterday my phone suddenly shut down. But it wasn't like with the old battery where the display just went black. Instead it showed the usual shutting down "notification" as if I turned it off automatically. When I plugged in the charger I noticed that the phone did show the lightning charging sign but was always stuck at 0%. That's why I assume that this problem is software related. Also when I am in the recovery I can unplug it and it won't turn off. Of course I already tried quite some things.
At first I cleared the cache partition - didn't work.
Then I downgraded from Android M preview to Android 5.1.1 using the flash-all.sh - installation did work but still won't charge or show that it is being charged.
Then I installed TWRP and wiped everything possible for several times and then used adb push command to move the latest cyanogenmod nightly to the phone and installed it - still won't show any change in battery level.
Do you have an idea what might be the problem and a possible solution?
Thanks in advance.
Have you tried another battery?
I'm not sure if it's more appropriate to post here
or on the custom ROM forum itself, but here's my battery issue:
Issue: Abnormally fast battery drain. My battery would
be fully charged, and almost immediately start draining until
it'd show 1% within 2 hrs. Screen would be off mostly (normal
use).
Been on a custom ROM since January 2017 (crDroid) and have had no problems with it since,
except 3 days ago, when the problem first appeared.
Things that are ON: LTE data (or Wi-fi), Auto apps update on
Google Play Store (never been problematic before), Location,
Things that are OFF: Bluetooth, ScreenCast, Caffeine
When I check Battery in Settings, the numbers don't add up.
I'd have battery indicator at 70% for example, but Screen,
Android System, all other apps would add up to only 7%. So
that's a whopping 23% unaccounted for.
But here's the weird thing: it drains fast until 1%, then at 1%,
the phone is supposed to initiate automatic shutdown like it has before.
When this issue cropped up, the phone keeps going for about 6 hours
or so before shutdown is started. Checking Kernel Adiutor occasionally,
I'd see a much slower decrease in voltage which probably reflects
more accurately the power drawdown situation.
Things I've done:
-clear cache (both through File Explorer and TWRP Recovery)
-clear batterystats.bin
-calibrate battery after full charge/discharge (via Root Essentials,
which basically does the same thing as manually deleting batterystat.bin,
if I'm not mistaken)
-Resetting App Preferences via Setting/Battery
None of the above has worked. Any idea what might be wrong?
My device is a Zuk Z1, with a 4100mAh battery. It usually lasts me more
than a day on normal use, but as the attached pic shows, it's at 96%
yet without having used any apps yet, has only 2 hrs of juice left.
I've tried reflashing my ROM, wiping everything including formatting data
yet nothing has worked.
I'm a light user, as I don't play games or watch videos on my phone.
Neither do I use graphics-intensive apps. I haven't used processor-intensive apps
that require constant GPS (like Google Maps, Waze) since then.

Have you tried flashing another ROM/going back to stock?

Not yet. Am going to try an AOSP-based ROM later.
I've been deleting apps piecemeal, but have faile to pinpoint the culprit.
I have almost come to the conclusion that it's the ROM that's problematic.
But if that were the case, why haven't I had the same problem since
when I first flashed this custom ROM months ago;
and why is the problem reappearing when that same ROM is re-flashed now?
OK, I've flashed 3 other ROMs: Citrus-CAF, NucleaROM and stock, and the problem persists.
By doing the above, I've crossed out the possibility of it being the ROM. Neither is it the battery
itself, because it would've shut down by itself at 1%, yet at 1% I can last 6 or 7 hours of light use.
Anyone out there have any idea?
If you get the same results, the battery is trashed. Is it aftermarket?

The battery? No, it's the factory original.
It would not be unusual for a battery to fail in a month or two. I've had that happen to a couple laptops where I work.

That would be pretty unusual for reputable companies. If ever it did happen in my case, perhaps it's a lemon batch.
Sadly, I bought this without warranty.
Not really, happens all the time in laptop world. Even with oem batteries.
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.
