[Q] Battery Life after recent software update

Has anyone noticed any significant decrease in battery life after applying the recent update issued by Verizon a couple of days ago? My Fascinates battery life was actually impressing me tremendously before the update, and it seems to have taken quite a big hit since the update. Just wondering if my case is isolated, or if others are seeing the same thing.

How many hours are you getting? My battery life always lasted around 13-15 hours even before the update which is still pretty short imo. I wonder if I have a defective battery. I turn everything off and brightness to the lowest but it's always around 13/14 hours when my phone dies completely.

My battery life has definitely takin a hit...

There's an UNCONFIRMED rumor floating around over on Android Central that Verizon and Samsung have pulled the update due to problems. Again, this is unconfirmed, and just a rumor, and makes NO mention to the reasons why. Perhaps the battery life is a more wide spread issue.

Well, isnt that special.
Took me forever to apply it manually and now it might be borked, great

I didn't really have a problem with the battery life after this update, but I did notice a signifigant loss of speed when going to websites or watching Youtube.

I installed the update by reverting to stock and updating, and then re-rooted and re-applied the lag fix, and of course re-removed bloatware. I can report that I have noticed no difference at all on data transfer performance, and also no battery life issues. In fact, when I got home from work today, I looked at my battery gauge, and it was still at 87%. That's after almost 12 hours of mostly standby time, with gmail, corporate email, and weather services updating regularly. That's actually the best battery life I've seen out of this thing yet. If your battery is draining faster than that, then you must have some kind of process or background service that's not letting the CPU sleep, which will drain your battery fairly quickly. I wouldn't be surprised if the culprit is one of the bloatware apps that I disabled.
On a side note, I still seem to have an issue where the data connection intermittently cuts out. I don't lose the 3G icon, and have plenty of signal, but it's like the connection just times out, and a few seconds later resumes again. I was hoping the radio update in DI01 would address this, but no dice. I'm actually suspicious that it's an issue in the OS itself, as I've seen similar behavior over WiFi, which is a completely separate radio and network interface. I hope it's just a software bug, not a hardware defect. If it persists after the Froyo upgrade, I plan on doing a warranty claim.

You should be able to redo the original root procedure as documented here:

Note that some have reported that they had to do the root procedure twice after installing DI01 to get root access back, though it worked the first time for me.

Yeah I have done it probably 7 times to no avail.... :/
It freezes my phone i believe after it sents the second restart command. it comes up with device not found, even after it says it was successful....
I also tried the original version of this program (i believe), but it is the one I used to root it the first time.

I bought the phone on the 25th and got the update within minutes of leaving the store. I got great battery life the first day but it's been more standard fair so far getting 13-14 hours with moderate usage.

I unplugged my phone about 12 hours ago. I have used it all day for email, text and phone calls and I am right now at 64%. I am getting great battery life with this phone, loads better than my droid 1 and 2.

Reinstall the Samsung drivers. I had to do that and then root was achieved again. I'm an employee of Vzw and haven't heard any rumors of the update being borked. I'll keep y'all posted!

This is from a normal usage of my phone. As you can see from the graph the last few hours were me connected to wi-fi constantly, tweeting, fiddling and browsing forums. Yes a quick drain but this is a phone!
My point of this post is compare this to tablets and netbooks. The majority last 6 hours, tops. The SGS II is a dual core, amoled phone. It was always going to be a beast on the battery. However if you use it wisely, ie only have Wi-Fi on when necessary, the phone lasts as this phone should.
It out performs most tablets and for the relative size of both screen and battery I would say that's hugely impressive.
Looking forward to your comments.

Your post is refreshing because of the following:
1) Clearly shows the display is the biggest drainer of battery. Anything else means you simply didn't setup your phone right or have some rogue app chewing stuff up.
2) You're not going bonkers with "OMFG my phone only lost 0% over 4 hours" and then post a graph that shows the screen was on for 2 seconds. Uh, well... duh! Completely stupid and pointless, glad your graph actually reflects real usage and battery drain.

I am actually fairly happy with my battery life
My Android OS has never gone past 10%
Getting around 16-17 hours with heavy-ish use, not bad imo

stock is fine, but tell us the kernel version

KE7

If you use kf2 you can get rid of the wifi sharing and save 15% battery.

now im gonna say this,
you people really shouldnt compare battery time like tht. Its the screen on time you should compare!! its far more accurate than this. i can get around 3h of constat use and connected to wifi. this is screen on time.

what's average screen time in hours for most users? i've been reading about 4 hours plus or minus 1. 8 hours is unreasonable on one charge? i like to read books so i am wondering about this. i highly anticipate this phone but the n9 kind of looks hot too if the rumor is true alien dalvik allows android apps on meego.

So what? You kinda never used your phone. Surf the internet connected via 3g and come back to tell me

So you use your phone less than my grandma and hardly get two days out of the battery?
Great, that's nothing to be proud of.
With this usage my Omnia7 lasted for a week but the SGSII drains harder than my kitchen sink.

I noticed light consumes unusually lot of power too .. I recommend not using it as torch. White screen works just as fine for me (in total darkness). It seems they put in even stronger LED then in previous models .. and it better be used just for the moment as photographic flash. Battery voltage drops significantly .. and it slowly returns after the LED is turned off .. which means it's really strained a lot.

I bet i can get 2 days of battery in the way you used your phone. Screen was rarely on, so you just showed us that you can get a day and a half of stand-by.

At the risk of being accused of grandma phone usage im actually fairly happy.. The wifi sharing thing is a ***** so axed that.
This is with stock but rooted ke7

I'm getting pretty good battery life aswell with stock kf2. The only thing I did is deleting some of he crappy samsung apps and froze wifi sharing. I get about 2 days of battery with normal use. And yes i do use the phone in these 2 days.

2.3.5 Kernel BATTERY NOT GOOD

I've installed the 2.3.5 kernel recently because people were saying it was great on the battery but i'm getting pretty tired of this...
Out of nowhere sometimes like this morning i left the phone screen off since 7.00 am full charge and i checked it now at 11.40 and the battery was at 79%... It has been awake the whole morning. I looked at OS monitor and it might be calendar trying to sync all this time without having a 3g connection or wi-fi... why would it keep the phone awake and try so many times to sync if i'm not under 3g coverage?
I used to get 3 days with 2.3.4. I'm going to revert back. Aweful update...

thanks for telling us

I thought it was calendare but apparently it isn't.
Only after clearing RAM has it stopped staying awake even with screen off.
No idea what this is all about.
How do i discover what's keeping my sgs2 awake?

Tell me about it!
I flashed XWKI8 and I have been having all sort of issues with it. My phone was terribly slow and very laggy. It was getting seriously heated up around camera.
And above all, I took it off the charger (100% battery) 7:30 in the morning and now by 3:30 PM I got no juice left in the battery! It just died upon me.
I think I will flash it back to our trusty KF3 update.
Does anyone know if I can just download it from Intratech's thread and update with ODIN, or do I need to get some kinda wipe package from somewhere?

i'm quite positive you just need to reflash the pda in odin

You have no idea what you are talking about. You start that the kernel is not good. Then you blame the calendar for keeping your phone awake. Now tell me how is that related?
You can't say that something is bad based on one experience.

If you read the replies you would've seen that calendar is not the problem...
And before the update the phone was NEVER awake if the screen wasn't on... So YES i think it's a kernel problem

Nonsense !
2.3.5 battery just fine ... better than 2.3.4
Gives me a full day when used intensive (3-4 hours of surf, mail, talk)
Gives me 2 days if used moderately
About ½% per hour standby

The real question now is... how can i see what is keeping my phone awake???

Search for 'Better Battery Stats' in XDA.
Besides, I don't think it's huge improvement in battery life in 2.3.5 than 2.3.3. I am getting almost same battery backup in recent KI3 which I was getting in previous 2.3.3 KF3. There are plenty of ROM's but I doubt there is any difference between then other than they are dedicated for different regions. It's basically a freaking thing to flash new ROM's continuously.

look at this thread http://forum.xda-developers.com/showthread.php?t=1290020
and check if it isn't the same thing that's bothering you. when you look at the built in battery stats, do you have a very high usage percentage of "Android OS"?

dude I am usin XXKI8 (2.3.5) with chain-fire root kernel KI8..
I have seen drastic improvement on battery life over KF3.. only 2% overnight drain on standby (with data connection off of course). smoother animations.. near zero lag while locking, unlocking, smoother browser.. the only thing that bothers me is occasional lag while opening gallery.. rest is superb..

I had that also, it's a ***** in Facebook app. You don't need to remove facebook app, just go to facebook chat and log off. I wonder why it's enable by default from facebook if they know this thing is going to drain battery like hell.

How?
Very simple : just delete it.
Your battery will thank you soon, and you will certainly stop pulling your hair out.
Anyway, you always can use mobile FB version which is actually pretty good.
Cheers

No need to delete, just use the app and sign out of chat, poor design on part of facebook, but like many others using android, no investigation, just blame the update or the phone......

nah. i did not know how to see what processes were keeping my phone awake. now that i know i'm a happy new man. And i'd also like to change the title of this thread!

Early report of Nexus 6 battery performance : Almost 6 hours screen on time!

What do you think???
With not so good cell reception (as he said) and so many wake-locks, I think it's pretty good!

Now lets see how the battery handles while playing Ingress!

I would be very happy with this if it is typical usage!

If I can actually get anywhere near this I will be very Happy.

Not as good as I was hoping, but still reasonable. That's right around what I've been averaging with my Moto X.

Not good at all.

The wake locks are horrible!
Sent from my Nexus 5 using XDA Free mobile app

I think that is looking decent, with 13% of the battery used being on 'Cell standby' it is clear that reception was not good during the day. On my nexus 5 when cell reception is good Cell standby barely registers on the list. Max of 5% usually. So would we be looking at 6.5 hours screen time if reception is good? Also no indication that battery saving has been used or not (doesn't look like it is, on the screenshots as the notification/nav bar are not orange). Or what screen brightness set.
Who knows. It is all guessing until more reviews are out.

Yes, same with me. On my Nexus 5 with quite good reception the "mobile standby" is less than 5%.
With that in mind, we will have more than this.
And see those wake-locks, horrible.
Probably some apps, services, or accounts need to be properly setup and configured.
More battery life from that.
And for more extreme, we can use darker theme
So, I am OK with this early report, it's a GOOD BASE!

I'm seeing similar wakelocks on my nexus 5 with the last preview. The one before it had much better battery life, at least for me. I think kitkit has better battery life than lpx19D. so much for improved battery savings in 5.0.

Yeah me too. My N5 was charged fully yesterday morning and it just sat at my house untouched all day, and by the time I went to bed it was at 75%, which is pathetic. That's the last dev preview. On KK, it still would have been at 100%, or at worst 99%. I didn't investigate what was causing it, but that was bone stock without a single app installed. It shouldn't be like that. Hopefully the final version won't have that issue.

im not impressed. my G3 can easily handle 6 hours of screen time. But its tweaked to hell. Im curious to see the N6 with tweaks. also, does anyone know what screen brightness was set to?

I agree but some people take these findings to heart and if the battery doesn't live up to their expectations they have an aneurysm.

LOL Oh. Yeah your right. Didn't realize that. I have wireless chargers everywhere "even made one that was non-slip for my truck" must have put it on one sometime and forgot. Sorry bout that guys. Didn't mean to post a false reading LOL But still I've seen pretty close to those numbers several times without charging.. Depends on what I've been doing of course.
Btw That was an old screenshot I just had in my gallery from not long after I got the phone.

Ive gotten 34 hours out of it so far im really impressed

I have the moto Maxx, Mexican firmware. I´m from Argentina.
Could you tell me guys the version and the baseband of yours?
Because it seems that the latin america version the battery is barely poor.
Thanks!

Damn... Going beast mode with this battery. Would've gone longer, but gotta use it more tomorrow when I'm out. Ya, I know I only have 4hrs of SOT. Haven't been using much

I assume anyone getting more than 48 hours of battery life is turning off data, or at least disabling updates/background data. Just out of curiosity, do you always keep that turned off, or do you just do that when you're seeing how much you can squeeze out of the battery? In my mind, the big reason to get a device with a big battery is so you don't have to baby the battery like that.

I disable data and auto sync. I've done this for every phone I've ever owned. Not to preserve battery life, but I have no need to have it on 24/7. I turn it on when I need it.
