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:

"lightbox_next": "Next",

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
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 :/

People usually talk about battery life for continuous usage, but i want to ask about battery life when leaving the phone off ?
After a few tweaks, i noted that betterbatterystats shows my phones has been booted on for 5 days 15 minutes, out of which it's been 4 days 5 hours 20 minutes in deep sleep; and only seen 1 hour 59 minutes of actual usage (screen on basically means when i'm actually actively using it)
unplug means when i unplug it from usb charging after it was already 100% fully charged.

So how does my phone battery stats compare to the normal life time for the Samsung S3 when not in use ? just wondering.
I give most credit to greenify for helping keep my phone in deep sleep mode most of the time. Apps that are waking my phone is mostly googlemaps, and greenpower (left this ungreenified because it managed when to turn on/off my wifi, when i open screen .... which it probably can't do if i greenify it)
other than the few wake locks; the wifi on is mostly due to syncs. I usually set my apps to at most only sync when i turn on the app, or at max once a day. Greenpower will trigger to turn on wifi when the app requests access :X
PS: i'm using wanamlite and adam kernel. As well as philz CWM touch for root.
Hello, 3 days ago I've installed CM10.1 nightly build from 2013-07-25 on my friend's Galaxy S III (international), now his battery life is really bad and he's complaining on me, any way I can improve the battery life?
Here goes a screenshot (as you can see, he wasn't even using the phone when the battery just dropped 50%):

Cyanogen mod roms are known to drain battery much faster than touchwiz.so you cant really expect the battery life to be the same as on stock or stock based roms. you may improve the battery life by using an app called Greenify. it hibernates apps so that they will not run in the backround. this can help considerably. also make sure to turn off gps , bluetooth, wifi. and mobile data when not in use.
well first tell your "friend" that thats how things are in AOSPs. Secondly use differrent kernels and proper setting to get max battery (tutorials are available) plus greenify apps you do not use. And the usual killers as GPS/WiFi/NFC/3G use only when needed or turn them off..
Something is extremely wrong there. Get a normal usage BBS dump and post it here. Also take screenshots of the BBS pages.
Also post a screenshot of your battery stats page (one that shows which apps drain battery).
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,
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 all,
I have a Note 4 910F on 6.01 (unrooted) with dreadful battery drain to the point where under use I'm hardly lasting a day or less which is ridiculous under medium/light use.
As seen in the images below the phone (since I got it) has been awake all the time (even when screen is off) except when its turned off. (I disabled WiFi on when sleep mode)
It will be awake in airplane mode and in safe mode so its not a 3rd party app problem. All bluetooth/nfc etc disabled. I have tried phone cache clear, app cache clear, reset.
I've used wakelock detector to grant battery stats via pc and see screenshots below for the wakelocks. I've then turned on the phone and have not touched anything for over an hour to show awake stats when the screen is off.
I've been all over the net searching for an answer but I'm pretty new to android stats etc. This is one of three batteries I have btw, all of which perform the same, so to me it must be software related. I am prepared to root the device to remove software that could be causing issue if it will solve it...
I have disabled Google+, Google Now, No Voice commands present at all or gestures.
Can anyone tell me the issue and how to solve this battery drain???
CPU Wakelock below (Partial) most important I am led to believe.
