Hello there, I'm new to the Galaxy S2 forums, I before had an Xperia Arc.
I have a problem that happened just last night. Last night I turned off my phone and left it, didn't touch it. That was about.. around 1 am, right now, 10am I woke up and turned it on. Samsung logo, ROM boots etc, I check the battery and I have 8% left. What??
I took these screenshots, Wakelock Detector screenshots would be useless as it only shows stats from when I turned it on, and everything's normal.

As you see it lost that huge amount of battery while turned off for no actual reason.
I'm not sure it's an "overnight" issue, I've noticed a random and huge battery drain on power off/on (even on reboots) on 3 different Samsung devices, using different kernels and roms.
[EDIT] Sometimes the battery even slowly recharges by itself with time, so maybe it's a battery stats-related issue [/EDIT]

Well yes you're right too, any idea of why this on/off huge battery drain?
Use battery stats plus..
And check what is causing battery tp drain
Difference in battery level after reboot is quiet normal thanks to the fuel gauze chip we have

Hello guys, I'm trying to figure our how much my battery can last on one charge, but I'm having a problem in the
Settings> battery,
Where it is supposed to show the usage.
Every time I charge the phone and plug it out, the graph doesn't reset back to 0 hours and just keeps on adding on the total time the phone is on. You can see in the graph the battery percentage keeps going up and down, I can't get it to reset on every time I unplug it from the charger, even by pressing refresh.
Is this a bug for me or is there a proper way to do it?

Hard to evaluate first part because only you know how intensive you use it. However, the bolded part concerns me. Could be a dud? Mine definitely gets warm especially here (check my location) but not hot by any means. Btw, do you have Infrared Thermometer by any chance?
Battery report only resets when your battery reach 90%+ and you unplug it
Hello , i'm on an investigation why did my phone died last night. Basically i left it on 33% and in the morning the phone was completely dead! Usually it never took more than 15% overnight. I was unable to determinate the problem via BBS because as you may know BBS doesn't really work on 4.4 Kitkat (even if set as system app). The only thing i can show you is the build-in battery monitor graph. See the red section - no screen times , no waking , no GPS , no Wi-Fi but the graph is still going down. I always keep an eye on my battery stats and overal phone health but this is the first time i'm experiencing such issue.

That graph is essentially useless/tells us nothing whatsoever. I'd be replacing the battery (might want to do a clean install of JB stock first to make sure it isn't a KK rom problem).

That graph is basically all i have without BBS.
Yes, I know that. And as I've said, it's useless. What exact information are you expecting anyone else to glean from it that you haven't already done yourself (We're not mystics) ? It's a simple/basic graph, it provides simple/basic information, which won't answer your questions/give you info to enable you to solve your problem.
Stock kernel?Any undervolting?Maybe it freezed and that drained your battery.
Hello,
I am using Nexus 6P with the unrooted N6F26Q build of Pure Nexus ROM. I have always had decent battery performance of this phone with my general usage. Recently I have moved to a new geographic location and I see a rapid battery drain while the phone in a particular building. I do not have cell phone network here, so I have AirPlane mode turned on, but I use WiFi for internet connectivity. My observations are as follows:
1. During the day time, when I am in building A, there is no battery drain. I don't use my phone much and the battery level does not drop by much.
2. During evening and night time, I am in building B, which has a different WiFi, the battery immediately starts to deplete rapidly and in the morning I wake up with a dead phone.
3. Suspecting that the WiFi might be the cause, I tried to switch WiFi off at night, but I still found my phone to be dead in the morning.
I captured the bug report data and tried to analyze it with battery historian, but I don't have enough experience to point out the cause.
This is what the battery historian graph looks like.

Same graph from another bug report, when the WiFi was turned off during the night:
Can someone see something unusual in the graphs?
I can share the entire bug report via PM if someone wants to take a closer look.
Thank you.

Hi there,
Try to do a full reset of your device, it might solve the problem, if not then it might be the battery. A battery fault is more likely to be caused by the number of apps on your phone running in the background, or a faulty charger if your country has voltage variations now and then I suggest you to get a stabilizer so any devices that have a battery won't be affected. But anyway, make sure you backup necessary files on to an sd card or on to your laptop/desktop. And then do a full reset by either going on to settings or by recovery mode.
Sincerely

Hi guys, I have a Redmi Note 7 and I'm using Pixel Experience ROM. I had experienced battery drain even with MIUI, but I don't understand what's causing it.
I used Battery Historian and these are the result. I got a very high discharge rate (20% and over) even if brightness is not at its maximum, but by reading BH results, I hadn't found out the culprit for the battery drain. The drain is there even when screen is off, but I limitated it to about 1.5%/h thanks to some Doze modification.
I'm actually using Greenify to hibernate some apps (like Instagram, Facebook and few more), because I've noticed that, without it, the screen-on discharge may rose of a (around) +3%.
How could I limit the battery drain problem?
have you used a custom kernel
Since Android 9 there is the Adaptive Battery Feature:

Enable Use Adaptive Battery if not already done yet.
Additionally turn off Wi-Fi, BlueTooth & Location ( GPS ) if not used: it should be obvious that the less these wireless modules are running, the less the battery gets drained. FYI: GPS drains battery greatly.
I'm currently using Predator Stormbreaker kernel, in an attempt to partially fix the battery drain, but things are same as before. Adaptive battery is on, but my phone keeps discharging fast :/
