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.

Foyo update...Battery life shortened ?

Has anyone noticed their battery life seems shorter since the update ? I installed the official froyo update last night and it seems I'm running out of juice much quicker than before.

At first mine ran down faster. I ran it all the way down. Charged it. And ran it all the way down again and charged. It seems back to normal.

I didn't have any issues. Maybe you changed something else as well? Could always try a few recharge cycles and see if it stabilizes..

I was running the leaked 2.2 and I flashed to official 2.2. My battery life is almost double what it was. I can't complain one bit about battery life, although I have other gripes with the official Froyo release.

I'm with icepop on this one.. I was running the stock rogers rom pre-update and now with the official rogers 2.2 I'm getting at least double the use before having to charge again.

I'm having battery issues with the new stock Froyo. I lose a huge amount of juce when in standby. I thought I may have my widgets updating too often so I charged it up and put it into airplane mode last night. The phone lost about 1% per hour in airplane mode. IDK what is normal but that seems like a lot to me. I didn't have any apps running, except my alarm was set for the morning.
I have SystemPanel installed and my cpu load NEVER goes below 10 percent, even in airplane mode. I suspect this is a large part of the issue. In app history, system and system processes are always on the top of the list and are around 3% each. IDK what controls this or how to lower it. I would love some feedback from someone else with SystemPanel just to see how our numbers compare. Overall the battery life I'm experiencing is pretty terrible and a buddy of mine's Fascinate has much better battery life (hence something must be wrong somewhere). He and I were skiing all day over the weekend and when we got back to our cars, my phone was half dead and his had lost almost zero juice. This displeases me.

mine's was better actually. but i didnt stayon it for long

My initial results with 2.2 were very bad (10% drop per hour when idling). I reset the phone back to 2.1 then re-installed 2.2. This did not help. Now I did this again (2.1 then 2.2) but this time I have not re-installed my apps and have not rooted (yet). So far, battery life seems to be normal. I suspect that some of my applications might mis-behave when installed on 2.2. I am planning to add them slowly and watch the battery.

Not here, seems the same to me

Mine is terrible ! I don't know what it might have been on 2.1 as I upgraded fairly quickly. Essentially I charge all night and then disconnect from power at 6:30am and then by 4:30pm I'm out of juice (phone shuts off). Any ideas here? I'm not running anything extravegant (email only) and hardly make any calls.

Whenever you flash to a new ROM, wait for at least a week of normal usage before you judge the battery life. The reason is simple, your battery stats are reset after ROM flash and your new OS needs time to learn how your battery drains before it can give you accurate readings.
If you can't wait for that long, you need follow the battery calibration thread to force a manual calibration of the battery.

I'll give it a week and see how it is then. Definitely is draining much quicker now though. I think It acted similiarly when I first got the phone as well. If I recall correctly the batter life sucked when I first got it, but then a week or so seemed to get much better.

I did the manual battery recalibration (let it die, charge while off, turn on and bump charge...etc). Last night I lost about 2.5% of battery per hour while in standby. This seems improved since calibration but its still pretty terrible IMHO. Is this in line with the amount of drain other are getting or am I draining more than usual?

Running stock since purchasing the Captivate back in August, and so far battery life actually seems to be routinely as good if not better than 2.1. I must admit I didn't use my phone a huge amount yesterday (except for about an hour plus of downloading a bunch of wallpapers off Zedge for some ungodly reason lol), and after 18 hours of the phone being on I was still over 50% battery life left. 2.5% in standby doesn't sound like all is well - you must have something running in the background or similar issue. I have a live background, sync 5 e-mail accounts (granted, only one of those is every 15 minutes - the others are every thirty minutes, every hour, and once a day on two of them), and with light use I am getting over 40 hours with 2.2 so far (about in line with 2.1, but seems maybe just a little better). Heavy use I am dropping more like to the 12 - 18 hour mark (heavy use for me means the screen on more than off, actively playing games or using apps, large amounts of texting, etc. Solid game playing I haven't figured out a drain yet, but on some games it seems like I can drop almost the whole battery in close to 10 hours). At your rate of 2.5% per hour in standby you would only make it forty hours without even using the phone. I have been using mine just a little this morning (FB check, logging in to one of the desktops at work remotely to make some changes, live background running, WiFi sleep policy is set to when screen is off, but to be honest that is about it) and I haven't moved off the 100% mark yet and the phone has been unplugged over an hour and a half.
All that said though, as other users have stated you might want to give it a little more time for the system to recalibrate the battery usage. I would definitely check your processor usage though regularly to see if anything seems 'off'. One thing that caused me problems was that my SNS service would be running but then would get stuck in a pattern of 'Restarting' - would drain my battery rapidly.

It has been said that bettery drain is not linear. First 5% goes real fast. So, you need to judget the average over a day of use, not first hour or so. I'm still in first week of ROM flashing. So I can't confirm anything yet.

[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.

Bad Battery life or Bad Battery on Nexus 5 with 5.1

Hello,
I've searching for like 2 months about problems with battery life and Lollipop with nexus 5. I understand the issues but since it was released, i never had much problems with it. I used to have 2h SOT for like 40% battery or so.
My daily routine allowed me to reach home with a bit more than 50% battery with 2h SOT more or less. (a lot of messaging on viber/whatsapp)
But something changed since 1 and half months ago. I can no longer do the same and it seems that i have a CONSTANT battery drain. I remember when i unplugged my phone i would reach my workplace (1:30h after unplug) i would have like 2-4% less battery depending on the usage. Currently when i get out of home the battery is already at like 92% or more depending on the usage. If i let the phone stay idle all the time, i usally get home with 30-40% battery now. I'm already thinking that my battery has gone bad. This started to happen from one day to another and i never let the battery stay too much below 30% usually, but nowadays it's impossible to predict the battery life since some days it seems to drain more than others.
I've used some apps to monitor the usage but i really don't understand much about it and can't seem to find a pattern. I've already did factory reset with all Lollipop versions and i remember doing a KK regression for some hours but the drain seemed like it was still there (can't use KK on my nexus 5 anyway, it feels weird after Lollipop experience ) but i didn't even fully charged the battery as i remember. Anyway if it would be an app, there should be some kind of logging in battery stats which doesn't, and i can't think about anything else.
I finally gave up and decided to ask help here, since i don't know what else to do. I'm actually leaning towards getting a nexus 6 but after reading about so many issues (screen/battery life/burn-in) i'm not sure what else i can do with my nexus 5.
If anyone can give me a hint i'd be very grateful
PS: already tried Cataclysm ROM and using currently ElementalX kernel. I notice a bit better battery life with ElementalX but i think the pictures speak for themselves.

Judging by that constant drain with very little shown awake time I'd install Better Battery Stats and check for kernel wakelocks. I had a similar situation with a wake lock from using a wireless charger that did not show in the regular battery stats.

i already installed it before, but currently don't have it installed. I have Wakelock Detector app i can post a screenshot if helps
Installed Better Battery Stats, i'll post results tomorrow (battery at 19% already).

As promised, there's still some battery left but i didn't even use the phone today mostly... in days like these i should be over 70% as usual or maybe close to 80% that i remember.
Can't seem to find the cause

bump i guess
will some full discharge cycles fix this ? iirc that can make things worse.

I feel your pain...when I was on Kitkat, I'd get to work running just Waze and Pandora and my battery life would be at 80%. Installed Lollipop 5.1 and now half way through my trip (15 minutes of use) the phone shuts down with a dead battery. Maybe it's just a coincidence that my battery decided to give up the ghost at the same time I install 5.1, but I find that very odd...the phone is only a 1.5 years old...lithium battery's tend to last 2+ years and even then they don't fall off a cliff in terms of capacity. At this point I think I'll buy a new battery and see what happens, LG OEM are about $25 on Amazon.
