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] Battery life with firefly 2.3

I am getting a very short life out of my battery. I run firefly 2.3 and with everything off i am at 50% after about 4 hours. any ideas please.
Samsung Captivate
Firefly 2.3
speedmod k13b-500hz #54

I'm not too sure.
I almost get 1% a little bit less than an hour 45~50 mins at idle.
This is no data and nothing on.
But once wifi is on, it ate about 15~20% in under 30 mins. This is with browser open and msn
I suppose data would be around the same if not a bit less or more underload.
I suggest do all those things that increase battery life ppl suggest on the stickies.

4 hours doesn't meant much without more info. You can have your phone on for 3 hours and been surfing the net or playing games the whole time so I'd expect your battery to be nearly drained.
How long is your phone on for?
What % is the display using up your battery?
How long has your screen been on?
After display what's next for battery usage?

I would go through all the basics:
- Charge to 100%, wipe back to stock and do a fresh install
- Charge the battery to full again, do all the basics to get a legitimate read (plug/replug, wipe battery stats)
- Check your about phone settings and look at battery use, check for battery hogs.
- Check to see if you are in an area with poor signal. I lose signal if I'm indoors where I'm at so I turn the phone to flight mode. If I don't it eats about 15% of my battery an hour.
I get consistently good battery life with my captivate/FF2.3, so I'm betting it comes down to a faulty install or battery measures.

I've also noticed this after I upgraded to 2.3 (from stock Rogers captivate). My battery used to be at maybe 70% at the end of the day, now it is at 20%.
I just checked it, and it is reporting 93% after 2 hours. The display has only been on for 2 minutes but has used 48% of the battery.
I have the display set to the lowest setting, no gps, no wireless, limited background apps.

ok i turned everything off and put into flight mode and set the screen to turn off after 15 seconds brightness set to the lowest point on the slider and starting out at 99% on my battery, after letting it sit for exactly one hour with no use at all i turned it back on and it was at 83%. how did it eat 16% doing nothing. I also did like you said with the reflashing and clearing of the battery info and still get the same results. do you think it may be a bad battery.

I'm getting great battery life with Firefly 2.4(no mods added) with WiFi on 24/7...might wanna upgrade, it is so easy with the on-board download and upgrade built in!

I made the mistake of flashing when I wasn't at 100% battery not knowing how much of a pain it was to calibrate the damn thing. I did however realize that after a couple of full charge/discharge cycles my battery life improved. FF 2.4 seems to have better battery life, but I haven't had it on the phone long enough to say for sure.

My first charge on 2.4 never displayed "FULL" in the top left like I'm used to seeing. I bump charged just once and cleared stats. Still couldn't get that "FULL" up there.
That said, my batt lasted 2 full days on the charge with minimal usage (3 or 4 calls, a few short youtube videos, 4 or 5 rounds of Angry Birds, otherwise with display off sitting by my chair on my wifi).
That seems like ridiculous good standby to me... perhaps too good. I'm afraid I might be badly overcharging my battery, so I let it drain until it I couldn't turn it on and it's back on the charger. I'm hoping I'll see a "FULL" up there this time. On the other hand, I sure could get used to that kind of standby time...

Good battery life thread

I've been sitting at 69% battery for the past hour and 48 minutes.

I've been using the phone for about 18 hours, and I am at 45%, ill post some pictures in morning, going to bed.
Sent from my LG-P999 using XDA App

it's been 1d, 10hr, 59min,
and I'm at 57%.
but of course very mild use:
about 30min of phone call,
25min of web browsing,
13min of XDA Prem
20min of music.
20min of clicking around randomly in the phone
I am a "minimist". I only run apps when I need them so I have pretty much nothing running in the background (except Google Voice). I don't even have a widget, only 1 screen of shortcuts. so put that into consideration before comparing your battery life to mine. I am just giving an insight about how I achieved mine.
Removed(deleted) all bloatwares (wifi calling, myaccount, lg.omadmclient)
Using Titanium Backup PRO, froze several apps (which I don't think matters, since I never see these apps running in the background anyways)
Using StartUp (the program), I disable A ****LOAD of things, so apps won't startup by itself due to whatever reason
did the HTC battery conditioning twice, then wiped battery stats
has a SetCPU screen off profile of 216/216.
no apps that sync at all (except Google Voice, which is constantly running)
default brightness
use ATK to kill tasks manually everytime I'm done using the phone, before I lock my screen (NO AUTOKILLING)
what I've come to realize is that no matter what u do, when you use the phone, the battery is going to drain. when my screen is off/idle, i lose almost no battery. For example, the day before yesterday, I lost 3% battery overnight (8 hours). Last night I lost 1% overnight (8 hours). But when I actually use the phone (screen on), i lose battery fast.

My battery life was awful the first few days but after uninstalling the capacitive buttons led notification app and calibrating my battery it got a lot better. It now lasts me the entire day with around 30% left when i plug it back in. I do turn off 4g when I'm at work and in a few of my classes because I dont get good reception.
The battery seems to last a really long time on idle but as soon as I play a game (guerilla bob thd) the battery drops about 10% in about 20mins (while im playing) and then goes back to about 5% an hour

Here's my battery life... http://forum.xda-developers.com/showpost.php?p=13438062&postcount=21

Haven't tried to stretch my battery past what I needed yet but I used it for 1 hour 2 minutes straight today and only lost 10% battery. No way thats happening on my old phone. Used to lose 1% every couple minutes the screen was on.

That's how much I'm losing.. the phone is pretty good when it's off.. when there's no network.. but I went from 65% to 45% in 1 hour, and that's just from texting, really not liking that.

Damn that sucks. I only lose 4-5% per hour of left idle. Something is prolly up with your phone.

You lose 4% - 5% when your idle? That's how much I lose when I'm idle, probably even less.
When I touch the phone, it starts to die really quickly

Dunno whats causing that. I drain pretty slow during actual usage. My screen brightness is usually 25-30 that prolly helps a lot.

Damn, same here man, what about GO SMS or Go launcher?
Does that kill battery?
I removed Go launcher, I really loved the look, but testing if that kills the battery?

I use both and have never experienced them using any more battery than any other launcher on either of my phones.

My TBird is schizophrenic

Running the stock unrooted ROM, I was making it to about 2:00PM daily (taking off charge at 5:00AM) before I had to charge the phone. Some heavy use days I didn't make it that long. So I bought an extended battery and for the next four days when I put it on charge at night it still had 40% - 50% battery life left.
Then yesterday with light usage my phone (with extended battery) was rapidly heading for dead by around 2:00PM. I didn't have any different usage but I had been noticing the battery level dropping FAST. The battery usage page said that the screen was using the juice but it only had a usage time of 10 minutes so this didn't make a lot of sense. When it still had 25% left I thought a reboot might help by closing something running that the task killer just wasn't picking up; but when it turned back on it had gone from that 25% to only 8%. Crazy. So I charged it up to about 50 percent before I had to leave work. And for the rest of the night before I put it on charge again at 1:30AM it had only used 3%.
Is HTC working on the battery issue for this thing in the next update? I've still got a few days left to return it and I'm seriously considering it. I'd really hate to because I came from a droid x and am really loving the Sense interface compared to blur. Even compared to gingerblur which i actually liked.
edit:
I installed juice defender last night. Pulled it off of charge at 5:00am again this morning. So far it's only used 4% of a charge. If Juice Defender continues to work this well on the extended battery I may swap back to the original battery and see if it will get through a whole day. I'm pretty sure this has something to do with 4g not working right at times. It doesn't drain the battery this fast every day, only some days. If it was just the way 4g works, it would always drain the battery the way it did yesterday.

This is most likely your problem.

Don't use a task killer, ever.
As for you Thunderbird being schizo, you should probably post about that in a Ford auto forum.

Battery drains unusually fast while screen off?

Last night before I went to sleep the battery was around 94% after an hour of solid use from a full charge.
I woke up today about 9 hours later and the battery was at 55%. It's been about two hours since then and I'm all the way down to 30% with only about 20-30 minutes of solid use.
What's up with that? Any ideas as to what I can do to fix it?

-Battery calibration, basically drain to 0%, then back to 100% on single charge.
-Try custom rom
-Might be radio, try flashing different found in development thread
-app or widget installed recently?
-look in battery use under settings menu to find what is eating up battery consumption, in your case likely something via cpu consumption (ie not display use)
What is your current set-up?
Check out battery drain threads in general section.

I'm working on battery calibration right now, this is my first day with the phone (I got it about 24hrs ago, actually). I'm gonna let it die then charge it to full.
I'm on a custom ROM right now, QuickWiz v1.0.3. It's blazing fast, no cool features though. I miss my CM7 that I had on my Inspire but the CM7 alpha was a bit too buggy for me.
I'll check into flashing some other radios in a few and I suppose it could be the weather widget I installed. I'll check that and see if it's syncing too often or something.
That's the funniest part. I just looked and I have 1h51m of screen on time (Mostly around 35% brightness, give or take a bit) and it's taking the majority of my battery at 31%. Right under it is Dolphin Browser HD at 13%. I might just swap to another browser, any recommendations? Last under that is the Android OS at 12%, then everything else is under 10% - Cell Standby, Speed Test, Market, then down to 5% which shouldn't matter.

are you using a cpu governor such as system tuner or setCpu? if you are OC'd, id suggest also cpuSpy to determine how long your device is in each state(clock speed)

I am OC'd. i have a setcpu profile for screen off that cuts it down to ~54/400MHz when the screen is off, set to conservative as well.

Hmm, if I had to guess, check the radio. I've had the problem before. As far as browsers go, I like Dolphin HD, just make sure you completely exit out of it when not using, otherwise it can be a resource hog on idle. Since you haven't had the phone long, reflash your rom of choice too if you get such a drive, that has fixed battery issues for me also.
I love my battery life using TPC's ROM with DaG's kernal. I'm also using TPC's CPU zip to govern and set CPU speeds 192-1782MZ without the use of third party programs. Some see zero battery loss when idle over night. I lose maybe 5%.

I installed a new radio with 8% battery left before I went to a birthday dinner. That 8% lasted me through light to moderate use at the dinner for about an hour and a half before, and I got back with 3% remaining.
I also froze a bunch of bloatware which could have also been taxing my battery. I'll wait another few days of use before I flash any other ROM's/Radios to make sure I'm not happy with the battery life and past that, I guess I'll just have to return it for a new battery or an LG Nitro HD instead, if the dev scene starts to pop up for that phone.

Can you link me directly to the CPU script zip?

what was the radio???
I just got the QuickWIz a few days ago and Im having the same battery drain problem while screens off.. its getting on my nerves
