Help on what's draining my battery?

The battery life on my Desire is horrible, and I would like to acheive some of the great battery performance I've been reading of other members. I've got LeeDroid 2.1a A2SD+ ver., with the 38.44 radio (I installed older versions in hopes of acheiving better battery). I am now getting far worse performance then when I had new versions of LD/radio, because "something" is draining the battery. ie. Before, I'd get 15% loss per hour during the day, and 1% loss per hour at night during my sleep, with the screen and wifi ON, (using GentleAlarm night clock, which shows the time but on a dimmed screen). Now, I have a 75% loss during 8 hrs of sleep! I even installed "Juice Defender" (Pro ver. with "Ultimate Juice"), which turns off wifi for a few hours, etc. It did nothing to improve battery life, or possibly made things worse. I tried uninstalling some programs, but nothing's changed yet. How can I find out which program or configuration is causing the battery drainage problem?
Battery Indicator Pro stats (8h40m since unplugged):
DISPLAY: 42%
CELL STANDBY: 26%
WIFI: 25%
ANDROID SYSTEM: 5%
PHONE IDLE: 2%
Quick Info stats:
Running: 95.9%
Screen on: 95.9%
Wifi On: 95.7%
Wifi Running: 95.6%

Wi-Fi drains faster than anything, if you're not using it then shut it off! Also, 15% drain per hour during the day and 1% at night isn't that bad. I would switch back to your first configuration. Maybe you're not taking into account how much you're really using your phone?

Well I'm comparing battery performance when I am NOT using my phone at all (during my sleep), and its night and day. When I was getting 15% per hr, 1% loss at night, that was with wifi ON (ie. JuiceDefender was not installed then, and it cuts off Wifi at scheduled times). I'd like to switch back to my first configuration, except that's my prob lem: I have no idea what that configuration was exactly. Lots of programs installed and uninstalled since. I'm going to take a look at a few apps though that might help me understand how to control battery performance.

Really bad battery life

I bought the Nexus 5 on it's release and sadly the battery life has been really bad for a few days now. The phone also restarted a few times randomly while being in standby.
This is my current battery usage (I hope it's viewable):
Yesterday:
h**ps://drive.google.com/file/d/0B5TjklEnFH1Kb3F1dkswQjdiYTg/edit?usp=sharing
About 1 hour of screen on time and the battery is already down to 41%, even though I didn't do anything on the phone, except watching the battery usage. I didn't even use the phone-app and it's still listed.
Today:
h**ps://drive.google.com/file/d/0B5TjklEnFH1KWTFwbEI0amVHdmM/edit?usp=sharing
Screen on time: ~40 min
Cell standby & Wifi running: ~8.44 hours
Phone idle: 8.8 hours

I'm using stock Android (rooted), a factory reset didn't help.
Is there a way to fix this?
Thanks in advance

Your second day seems normal. Nothing to worry about there.
The first day battery killer was the Battery stats plus app. According to your graph it started draining after you rebooted.
On a typical day for me Android system, Android OS, and Google Services all hover between 12-6%

You can try loading a custom kernel and tweaking the CPU settings, you can load the app Greenify

[Q] Super Fast Crazy Battery Drain on Cyanogenemod 11 Nightly Solution Needed

I just installed CM 11 on my xperia V but then I'm experiencing this terrible super fast battery drain. It's been 3 days. The first night I installed it it drained my whole battery while I was asleep. Usually standby time is great before I installed CM 11. Maybe its because of the sony stamina extended standby mode thingy. Last night, I reckon that it's probably because of the background process and the wifi, so I reboot the phone (so that all apps are killed) and didn't turn on the wifi. It eats 7% of my battery. Dafuq???
So, I checked the battery stats and 82% of my battery is used on android system. Then, I turned off location access. Brightness is at its lowest. It was on aeroplane mode. Bluetooth is off. I underclock the device to clock only at 1 ghz and i clear all recent apps. Only the wifi is turned on. I only left it for half an hour without even touching it but my battery went down from 100% to 93%.!!! Can you imagine?? This sucks. Can anyone please help me with this issue? Imagine after an hour my battery would be at 80%. That means i can only use the phone for 5 hours!! That is without any connectivity at all with slow processor and low brightness. If I were to push it to the max it would take maybe 2 hours of usage. I uploaded the battery stats included with this thread.

[Q] The battery drain is more fast when travel around

Hello,
I test the battery drain with these two scenarios:
1. When I charged the battery to 100% , then place it in my room for overnight, and I found the average usage of the battery is 2/% per hour.
2. When I charged the battery to 100% , then take it to my office, I traveld and use whatsapp for a while, then I found the average usage is 4.2% (Sometimes, I think it is also 4.2 % even I don't used whatsapp)
3. I think when the my phone galaxy N7000 with 4.1.2 Jellybean is traveled, the battery will drain more fast, I found the wakelock time of multipdp and secril_fd-interface is almost doubled for Battery Better Stats when I
Traveled the phone.
Question:
1. Is my guessing correct?
2. If it is, how can I reduce the wakelock time if I traveled the phone?
Thanks.

I've always found this to be the case on Android phones - haven't figured out why.

New Galaxy S7 Edge overheating and rapidly discharging.

BIG PROBLEM
A brand new, fresh out of the box Galaxy S7 Edge [Exynos] (came pre-loaded with Oreo 8.0), merely 5 days in use is overheating (gets to 41°C) and draining its battery strangeley fast (about 1% every 4 mins whilst on 3G or LTE). No apps have been downloaded from the app store and there are only a few screenshots on the phone, other than that it's empty!
I first ignored the overheating when I set it up as by default it had been charging via fast charge so it was understandable. The first day the battery consumption was "ok" since it was just idle and i was bareley using it. The following day I connected to the wi-fi and I noticed it was draining the battery pretty quickly..almost 1 % every 7 mins even tho the screen was dimmed and most apps had been "optimised". I was also worried about the "cell standby" drain which was about 2% every 1.5hrs.
But things began to get out of hand when I began using the 3G connection to watch youtube videos, after just 8 minutes the phone became scorching hot to the point where I couldn't use it for a while. The battery percentage was falling ridiculously by around 1% every 3 to 4 mins, with the display on 40% brightness, apps optimised, background apps limited and all the other tweaks to save battery life being utilised. Location, BT, Wi-fi, NFC and auto-updates(GooglePlay) were all of and it was still getting hot.
Then I allowed it to drain completley to 0% but before that I disabled "fast charge" , it took 8 hrs from 2AM to around 10:14 AM to reach 100%...but this did not help the battery drainage as it was still the same as before.The cell standby reported 3% use in 12 hrs which is abnormal since other S7E( Nougat) users only got a hit 1% in 8HRS. I then came on XDA and saw that many other S7/Edge users that are running Oreo 8.0 were experiencing the same issue with no resolve... I have tried ALL of the following with not a single positive result:
1. Soft reset and wipe data cache partition. 》no difference made
2. Enabling "mid power save mode" to limit CPU speed and background apps . 》 still overheats and drains battery as before
3. Factory reset the phone (there was not much user data on it aside from 5 screenshots). 》did nothing to remedy the situation
4. Disabling any apps that might have been responsible for the overheating and battery drain uaing the Apps manager and the "app power monitor". 》no noticeable change
5. using the "Optimisine apps" option in the App manager
none of the above helped as the phone still gets very hot (when it is on 3G/4G data) and drains its battery much quicker than S7 Edges that were running Nougat a few years back.
AT THIS POINT I'M ALL OUT OF IDEAS AND YOU HELP WOULD BE GREATLEY APPRECIATED.

I recommend to update / flash latest firmware available.
Then install a battery stats app like Better battery stats (BBS), record an idle dump and post it in the BBS thread (https://forum.xda-developers.com/t/app-2-2-05-oct-v2-4-betterbatterystats.1179809/)
There are some experts analyzing your stats and giving advices how to optimize your system to gain better battery life.
