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.

Within the last week, the battery life on my Charge has gone to hell. I used to go a full day plus before my battery died. Now I am lucky to make it through the work day without it dying.
Today, my phone has been unplugged for 3 1/2 hours and already down to 45%, and that has been with light use ( a couple of email and texts and one phone call).
What could cause this drastic change? I am on a stock Charge, and I haven't changed anything recently to affect the battery life.
I had this same thing start happening and from what I can tell looking at Watchdog the gallery is burning up the CPU, 60%+ utilization of the CPU and I hadn't even used it since restarting. I turned off syncing with Picasa to see if that helps.
I did a factory reset, and it fixed my battery life problem. After 1 day and 1 hour, I am still at 26% battery. Much, much better.
I don't know why this is happening... and I am doing quite a bit to try and alleviate it.
When I first got this tablet the battery was fantastic and it maybe used 2% over night when I slept. Now in one hour it can use 3% to 4%.
I have done the whole 9 yards of flashing back to stock, factory reset, all of that.
I sent this in recently to Samsung since I was having SOD issues and told them to fix this problem too but they fixed my SOD problem but not this one.
When in the battery use area in setting android is using any where between 12% and 40% of my battery with over 10 minutes of CPU time. When I first got this tablet android OS MIGHT have used 5% on a bad day.
I am saying this is the problem in terms of my battery but any input would be appreciated.
Edit:
Here is a screen cap of my battery usage (ignore that white line on the graph that was when I flashed LA3 back on to the Tab)
i know there are a lot of other threads out there, but I haven't found one that talked about the problem deeper and has a fix. anyways, I'm experiencing a serious battery drain where I charge my phone up to 100, unplug it in the morning, go to school and leave it in my pocket for 2 hours, and it ends up being 70-80% and the screen on time isn't even on the battery stats because I've barely used my phone to have it show up. As im typing this on my phone, ive even lost 2%. Is anyone experiencing something similar and is there a fix for this? At 33% now, according to the battery usage, cell standby is at the top of the list with 10% and screen on time is 25 minutes . Thanks so much
Please post some screenshots of battery stats and someone may be able to help

My phone is the same way. Even with the latest update that made cell standby way better where it sits at 1-3% my phone drains like crazy. It's been off the charger for 3 hours and 1 hour of screen on time and it's at 57%. They need a bigger battery in the s7.
Check to see if you have a VPN app installed, Firefox, Candy Crush (or other King app), or a weather app. Many use mdnsd that eats power. King apps send data all the time. And there may be some adware that you have that is eating power. Hope this helps...

Battery Drain
I have had the same problem. With the earlier update I had the issue with (what I consider) excessive drain caused by cell phone standby. With the latest update cell phone standby has taken a back seat to Android System. Here is a screenshot from today. As you can see Android System has more than twice the percentage of anything else. I reset the phone a couple of days ago but that had absolutely no effect. Went to a local Verizon store to complain which naturally went nowhere.

I did a factory reset in recovery wiped cache twice and rebooted I have had much better battery. 20-30% higher when I leave work. I also kept WiFi calling turned off not sure if that was the drainer.
Recently the battery life on my Z5 has been playing up quite horrendously. It just dies at random points and barely lasts a morning with a 100% charge. Every so often it will die and display a dead battery when I attempt to turn it on then, then after half an hour or so it just comes back on but then dies again even though it displays a full battery. I've been keeping it on Stamina mode and that makes no difference. I've ran the in built tests and it comes up saying the battery is fine. I've attempted to drain the battery and charge for 24 hours which didn't do anything. Does anyone have any ideas what I can do?
Thanks
Looks like you really need a new battery
How old is it ?
Was it used heavily ?
Do a clean install or reflash the firmware with Flashtool.
Started trying that and then it just stopped working completely. So decided to send it to Sony for repair.
