[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:
http://forum.xda-developers.com/showthread.php?t=779238
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!

Battery Life Issue (Is this normal battery life)

I've been noticing my battery has been draining a lot lately, and the majority is going to Android System. I did a search and found another post about this with no answers. I'm not getting much more than 12 hours on a daily basis, and I hardly use my phone. I'm including a screen shot of the battery usage. Is this a normal usage amount? I remember this phone being better on battery than this.
What are you guys getting for typical usage?
Anyone have any suggestions?

as of yesterday, I'm seeing the same problem. Didn't have short battery life before that but several apps updated yesterday morning and now I have something like 50% on Android System and an unusually high "Stay Awake" - we're talking something like 10 hours when I wasn't using the phone for anything in particular - certainly not 10 hours worth!
So, I'm wondering how we tell what is keeping a phone awake?

usually we need more info such as what rom your using and when it started to happen..
second post might be one of the apps thats causing it so id backtrack them n see if u can find the culprit

I had big time battery issues when I was running NI2, and similar to what you were seeing Android System and Kernel, my battery would be nearly drained after about 10 to 12 hours. I rolled back to NE9 and my battery is back to being great I am usually at about 60% after about 10 hours. For what it's worth apps and programs were the same between both builds. Not sure this is much help just figured I'd share my experiences and what worked for me.

This was the solution I feared. I'm having massive battery drain on NI2 as well. Unfortunately, won't we lose "HD Voice" or VOLTE if we roll back to NE9? Not a deal breaker I guess.
It's really too bad Samsung/Verizon broke the phone with an update. This is seemingly pretty common now. Hope another small update gets released soon. I'm on international travel starting Friday and having a phone dead by 3pm doesn't sit very well with me.

Yes, you will lose HD Voice / VOLTE unfortunately. That was a sacrifice I had to take I couldn't deal with my phone being dead by 5:00pm.

agreed. Yesterday was a complete joke. By 2pm with light use, I was down to 21%. Dead by 3:30.
I hate that I have to flash my phone back to a prior version because Verizon/Samsung broke it.

Wake lock detector and greenify are your friends...

My about phone.

so, after posting the second post in this thread I'm happy to post that my battery consumption returned to normal by the next day. I don't know what was going on but I'm still on NI2 and regular battery consumption - what I've been used to seeing on the phone all along.
that said, it's great to know about some of the apps that are available for better tracking/info about wake-locks and battery use.

© «Get best battery life & screen touch fix - EUROPEAN 815 only»

For information...
I installed the latest c firmware (d in build prop) with LG flash tool (NOT UPGRADE), a CLEAN install.
wiped(factory reset) before flashing, then in flash tool cleared and made a CLEAN install and factory reset after to be safe (3 resets) .
Now I get very few screen misses, and screen on time 4.5 hours.
Before this I got screen on time maximum 2,5 hours.
Just wanted to let you guys/Girls in on this as it worked perfect for me and my wife.

Thanks for the placebo

Think I've been around enough to make an accurate judgement, add I'm an recognised developer, I made a hell of a lot of mods and ROM's all developed for two things only battery life with good speed.
You don't have to believe me, what matters is for me, add I got a much better phone.

Hi smaberg,
I was wondering if you are on the Euro 815 version of the G4? Based on your post I'm guessing you are? As a guy who knows what he/she is doing, I was wondering if you could make a flashable zip of the version d firmware? I have a mac and my understanding is you need a pc for the LG flash tool?
Figured I would ask and would greatly appreciate if you could help!!

Do you have the same set of apps installed as you did before the firmware and resets?
I saw better battery results on my second G4 vs my first, some of which I assume was because I installed a lot less apps on the second unit. Which seems reasonable to me.

What device is the OP using?
Sent from my LGLS991 using Tapatalk

I'm on international 815 (Euro).
Still using the exact same apps(didn't use LG backup Restore as it brings back the old draining Barry problem from my old backup).
And NO I can't make an zip, as it would skip some important steps. I mean I can make it, NO problem, but then you will end up with the exact same problem add the old.

hey Smaberg, can you outline the step to flash the new version? I'm using 815, but since i'm residing in Asia, my phone is not seeing any upgrades.

Yeah i also like to get exact steps you made to flash

lol at 3 factory resets..just makes me want to skip the whole ordeal
it's 2015 and google (+manufacturers) still can't get their **** together even when using the most powerful hardware available
android 5.x has been utter failure imo.

@smaberg, 4.5 hrs screenon is nothing to be specially proud on, yesterday i had 6hrs with 12.5hrs on battery. Device is H815 and firmware is v10c howecer, i got my device on saturday and did just root it this night... we will see how it behaves now.

Me too, but I did one before flash, one with the flash tool as I chose to make a CLEAN install, and the last mostly to be sure.

I know, but compared to before, with only 2 hours, sometimes even less worth stock a and b I'm pretty ☺ happy, now I'm going to deactivate some junk and see the results, and when I'm done I'll share it.
I'm trying to get the best battery without root, then with root and some of mine scripts and files mod. And we'll see where we stand. In the end maybe an ROM pure made for battery as in the old days. If some still want this? I thought/think people mostly want bling bling and speed...

Hi,
I would definitely be interested in a battery life based ROM. I find that premium phones have more than enough power you need (if youre not a gamer) so as long as the UI is smooth battery life is more important to me.
Regards,
Ravi

Only used 4% battery and got this screen on time. With everything on.

You can turn it on manually which some people do to prolong battery life rather than just when on low battery.

Correct I have it on pretty much all the time. It doesn't effect anything I do on the phone and I get a lot better battery life as you can see combined with the use of App Ops, DisableService, and greenify

Serious battery life problem after update yesterday

So guys, I love my S7 edge, as I'm sure a lot of you do, but after the update yesterday my battery life has taken a serious dive in the wrong direction.
Turns out its the Bluetooth, except I haven't used Bluetooth all day, I've been at work, where I only look at it a few times a day.

Funny thing is, bluetooth was never on.

Damn if restarting or clearing system cache in recovery mode doesn't work you might need to do a factory restore

I was thinking "Oh great, yet another dude complaining about losing 5 minutes of his 8 hour SOT", but I'll admit this is a weird issue, especially if you haven't enabled or used bluetooth at all. Have you checked with a different logger, like Gsam?

Yeah I'm not the type to moan about poor SOT. The battery life on this phone is among the best. But yesterday was just terrible. Seems today it is doing better. Only time will tell.

I also have battery life issues after the APD1 update. Whereas before the phone had no problem lasting 48 hours, now it struggles to last 36 hours (Exynos here). I hate these stupid updates: notification LED is dimmer under most light conditions, battery life now sucks...thanks, Samsung !

I know you are going to hate this, but do a factory reset. Pain in the ass I know, but your battery will be back. Happened to me on the last update. I was relieved after the reset.

Is your phone at&t?

Here's a thought, I also had pretty "bad" battery life after the previous update, and then it got back to normal after I re-enabled the stock Samsung apps that I had previously disabled, so enable them again and let them be for a day or two and see if you notice any changes. This doesn't apply to your bluetooth issue, but I just thought of this now.

if you have app backup set up through google it should be automagic

Im in the same boat... but i did a factory reset when i installed echo rom. My battery is lucky to get 9hrs with 4hrs screen time. Befoee the update i was getting 14hrs battery with 8.5hrs screen time. Its the 3rd day today so ill see how it goes cos i know it can take a while for thr phone to settle

Cool. Thanks for the tip. I've experienced exactly the same thing with this update - was getting about 48hrs with just shy of 6 hours screen on time. I have a long weekend coming up, so I'll see how it goes and then restore if I think it needs it.
I typically use Ultra Power Saving Mode overnight. It lost 13% last night in about 9hrs. I would have been disappointed with anything more than about 2%. So hopefully a reset will fix this because I've been loving the battery mode up to this point!!!!

that backs up the apps, but not the "app data" which is a internally saved to the phone itself.

Basically my "Android System" usage went from 2-3% to 17-19% after this update. On the Exynos. So now the Exynos is now as bad as the SD820 at battery life.
I will reset my phone to factory right now, if this does not solve it (and I highly doubt it) then my only option is to flash the old APC8 firmware (it's possible to do it without rooting, right ?)

Use Samsung's own Smart Switch Windows application to take the backup.. It backs up everything, your Msgs, Contacts, Documents, Images/Videos, Apps and their settings..

I'm not sure what's going on with my battery life but it's less than five hours... I've had since noon today and it's already been charged once and taken off around 9pm tonight and I'm already down to 55%. Any ideas? I've hardly done anything other than texting and web browsing, all on wifi. I'm also not getting detailed battery stats. See below... Also, how the hell do you take a screenshot other than using screen write? Oh and i never got an update...

did the device reboot into a recovery to install the update? curious is someone dropped the ball and left a open bootloader on the released device OR its just the monthly security patch, prob the latter...
further investigations...it did include a new bootloader. i would hold of on installing this if you want root. you never know

Lol yeah not rooting, leaving it alone

I did not install the update. I just love that they say that ATT wants to install an update and give no more information as to what or why. After my upgrade experience I'm not real trusting and was hoping someone could report what it is. Want to compare?

Sadly, it's probably a bunch of good fixes bundled in with some unwanted bloatware and security "enhancements". Lol
BUT... that's just pure conjecture on my part, as I watch the N7 forums and live vicariously through you all. I'm still happy with my rooted Note 3, can't justify the upgrade cost, can't live without my IR blaster, and so will wait.

So, anyone know whats in the update(is it just the Android Aug security update)? Any chance it really would affect root? For me, the only reason to not root is Samsung Pay and since it doesn't support either one of my cards, not worried about that "feature".

It does contain a new Bootloader, and the update was prob forced upon you. Yesterday my device buzzed in my pocket, heard the ATT ding ding dong sound. Pulled my Note out and it was optimizing apps (about 50 of them). Seems they forced the update to my Note, even though I had clicked "install later" many times through-out the day. bastards!

I believe it's just a security update.

I did not get update. Do you have to have a att simcard in phone to see update.

The only way to keep from downloading an update is to have Wi-Fi turned off or disable the update totally with package disabler pro. The phone automatically downloads any update if you are connected to Wi-Fi and will install it even if you hit install later. The phone does the install after the third time you decline it. All of my Samsung phones have done this.

Okay i sh*t you not, I read this on lunch and said in my head there's no way it forced itself, or maybe it's an option to disable under developer settings. Got off lunch and felt my phone vibrate because it was turning back on. Pulled my phone out and saw that it was optimizing apps and I'm like like wtfffffff out really forced itself. I wasnt on Wi-Fi or anything and my phones battery was at like 30% so i honestly couldn't believe it did the update as such a low battery without asking, crazy. ?

The device is brand new. You can expect battery improvements over the next few days, no matter what you do. It takes 3-7 days of charging and use for the battery to reach maximum efficiency.
