Again with the Battery

Is anyone that is having battery issues running Adao Task Manager and Battery Status Pro?
I just factory reset my phone and I got 24hours of batter life. About 8 standby but a good deal of texting, web, some calls and some you tube.
I installed Task Manager and Batter Status Pro last night and my battery this morning went down 15% in about 1hr.
I uninstalled these today and will post again but has anyone else seen big battery drain from these apps or does anyone that is having issues running something similar?

I have been playing with the battery for about a week now.
For me this phone runs pretty good during stand-by. I would have about 2-3% drop for a whole night (7 to 8 hrs), with Google (push), Twitter and weather syncing.
The problem is when you use it, it drops like crazy. When I read news or surf the web, it would drop 1% every 1 or 2 min.
This morning I read an ebook, with black background for about 30 min, it dropped about 3%.
So basically i think the screen, data connection, and non-black background are the ones that kill the battery.

Yea, I agree, the S-AMOLED screen in this thing is an energy hog. OLED's are supposed to be more energy efficient than typical LCD's but I'm just not seeing it. Whenever I look at battery usage stats it shows the display at 70-75% of battery usage. Thats ridiculous. I have until the 18th, but I'm quickly leaning towards returning this and just getting an iphone4. This phone is becoming more and more disappointing the longer I have it.

This morning I have been uplugged 4.75hrs and used 16% no battery monitor and no app killer. Basically done the same things I did yesterday. Some Bebbled,texting, email, phone calls .
I will update tomorrow with total hours battery life for today. Would be happy if I can replicate the 24hours I got the day before installing those apps.

I got like 45 hours of battery with moderate usage during the two days. Seems fine to me, I occasionally used system panel to monitor if anything was using high and constant CPU

This is pretty typical of a 1ghz phone My nexus would last a day of heavy usage, 2 days if i use it lightly. We need to wait for undervolted kernels to be developed xD
Also, it really helps if you disable 3G when you don't use it. This allows me to get 3-4 days of light usage out of my nexus. I haven't played with the Captivate long enough to know how much of a difference this makes on this phone though

when you guys refer to "stand by", what exactly do you mean? Just screen off/phone idle? The battery usage on my phone when I use it seems to be OK even if not amazing, but it continues to sap life from the battery when I'm using it at an alarming rate.

Standby is when the phone is idle/screen off/locked.
The display is definitely power hungry. Using the Power Control widget that comes installed definitely has helped with battery life. It will let you toggle WiFi, BT, GPS, Data Sync, and Brightness (at 3 levels). When I'm not using anyone of those, I turn it off. When I'm indoors, I'll set the brightness to the lowest level. I'm usually at my desk when I'm streaming music, so I'll have it plugged in.

Actually they are more energy efficient on black screens, But screens with a lot of white in them suck battery bad.

This is true the white screens burn the battery etc. I just wanted to let everyone know what I did to make my battery last more that 24hrs.
First, read the Wiki guide and apply some of the battery saving tips.
Second, UNINSTALL a program called "gReader" created by noinnion. This program is a huge battery hog! At least it was for me.
Hope this helps.

Well I guess I am one of the "lucky ones" Im running a live wallpaper and have not run my battery down since the 1st day. Right now Im at 40% life and at 15 Hrs 30m since unplugged. This is with checking facebook, twitter, email, phone calls, internet browsing\video watching and following the steps for the GPS fix. The only thing I have done is install ATK on the phone, besides that its all stock.
One thing I know is a huge battery drain is Time without Service. Check that stat and see if you have anytime at all without service, if so, I am pointing to that as a major drain on the battery. I know currently I have 0% Time without signal, my fiancee however is usually in the 20+% range and her battery drains like many reports I have seen here (she has an EVO).....

Yesterday I only managed 16 hours. Web, Email, A bluetooth file transfer, short bit of gaming. I have about 5% of the cell standby time (26%) without signal. My girlfriend has the Aria which is running Android 2.1 also, has all sorts of widgets, haptic feedback on and can make it at least 24 hours. I get that it has a smaller screen but it is also an LCD. Shouldn't the Super Amoled be saving our battery some display consumption.

i get about 14 hours or so moderate usage and at the end of the day, i have about 35% left at night.

If you detail the "Display" usage in the battery usage details how many minutes has your screen been on? Mine says 1hour 2mins ...this is for 8 hours of running time. My display is using 50% of the battery (which is at 68% now).

W00t W00t today I have reached a new high 2 Days 6 hours and 29 minuts with 12% battery left.....

What I have found is keeping Wifi on while I am at work and home like almost doubled my battery life. Which is great that I can use Wifi all day and not drain the battery so fast like my Fuze. Right now been off charger since 7:30am and I have 84% left. Yesterday after 9 hours I was still over 50%. For me its better than any other smartphone I have owened.
I used manual brightness, (swipe notification bar), turn off GPS/BT. black wallpaper and set Wifi to never sleep. Also the power saving mode in settings is off for other reason and doesn't affect battery.

At 18% right now and it's been off the charger for about 30 hours. I noticed yesterday that while I was connected to wifi at home (with Y5 app), it was draining faster than when I was connected to 3g. Did some tested back and forth and JuicePlotter clearly had a noticeably steeper downward slope for when wifi was connected than when it was using 3g. Weird :\

battery life

anyone feel as if their battery life sucks? I do have 4g on at all times but I didnt think it would make that big of a difference in terms of battery life.

See my post here:

Try installing a monitoring app and see if your init process is hitting the CPU hard. I haven't heard from any other mt4g users with the same problem, but lots of.desirehd users have it.
I also have seen my suspend process eating 50%+ CPU when the phone is locked/screen off. Haven't found a fix for that yet though.

I'm getting a full 24 hours of heavy texting, moderate phone calls. Battery life is better than my magic... im having no issues.

Yes, I woke up this morning and my phone was already blinking and battery is on 8%. I left it overnight with more then 60%
A big problem also is that SetCpu cannot force the scale. If limit to 768 Mhz it still scale to 1024. So not I am sure that my ScreenOff profile with 245 Mhz DOESN'T WORK!
THAT'S SUX!!!

Weird I leave my phone at full overnight and its still at full when I wake up.

Try disabling the preflock that might help before I did that it wasnt scaling properly now afterwards it is.
Sent from my HTC Glacier using XDA App

I have frozen a few apps and use advanced task killer every time i start up 9a lot of apps come on at start-up).
The result is pretty good battery life. I have only gone dead when I had a few apps (like GPS navigation) running in background and forgot about them.

I'm having 0 issues with my battery. It easily beats out the battery life on the Samsung Vibrant I had.

I'm having issues too. My battery life today was 40% at 1 PM, and when I left this morning, it was full. I hardly even used the phone except to check email :/ I have brightness on auto and wifi off. Not sure what the issue is.

My battery life has been really good. A typical cycle is charge to full and disconnect power at 10:00 pm. Up at 6:00 AM, battery is still on 100%. Today my use has been moderate to heavy. It's now 2:30 PM and I have 68% left. I typically have around 30 percent left when I put in back on the charger. I'm happy with that.
Wifi, Bluetooth, GPS, etc., are kept off until I use them. I do however leave Background data and Auto-sync on all the time.

I turned on USB Debugging as recommended and my battery life is much better. Right now it hasn't been charged in 9 hours and is at 79%. I've downloaded 2 apps, updated 3 apps, sent multiple emails, light internet use, and 3-4 calls. I'm unrooted and don't use any task killers.

That's awesome. I'm going to turn on USB Debugging mode and see if I can squeeze a little more juice out of it.

I have had intermittent battery-drain issues too. On Saturday morning my battery went from 100 down to 76% in a matter of an hour or two with hardly any use. I did a restart and it seemed better. I've also gotten into the habit of restarting my phone once a day, right before I take it off the charger in the morning. I've turned off quick boot, which I read somewhere in the forums can affect battery life. It's been pretty good the last few days. I'm at 68% now off charger for 9.5 hrs with moderate amounts of wifi, web browsing, email, and 3G network usage. I'm new to android devices so I don't have much to compare that to, but it's working for my schedule.

heavy user - fully charged phone at 7am ... start using after 7:30am
check emails, fb, txt, barely to no calls.....phone will be down to about 20% at 1:30~2pm....
yes the battery is lame...but this is a known issue with HTC...the 3.8 screen drains a lot of battery also the constantly searching for HSPA+ and 3G...
I do notice when screen is off....this phone still drains battery !!! bad =(
left over night at about 65% left in the morning I got red blinking led saying phone is below 10% .... 50% gone!!!
I think restarting the phone after a full charge is a good idea....also maybe turn off quick boot?
*update* yes I found that when you have a bad signal and it's jumping between E and H ... this eats up battery
also installed Advance Task Killer (for froyo) this helps~ now from 8am my phone can last until about 4pm getting about 3~3.5hrs more life

Mine lasts all day with everything on, playing games, email, text, etc, etc.
It is great, best phone I have had. Not sure what the issue is unless it is root.

It depends where you live.
If you get a good antenna signal, your battery will last.
At my apartment signal is low, so phone is constantly between UMTS and GPRS, plus phone is trying to hold H, so that drains the battery.
My signal strength parameters:
between -101 dBm and -107 dBm (where -110dBm is the edge of the signal/loosing signal)
3 asu and 7 asu

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.

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.
