Kitkat killed battery life

Kitkat killed battery life. Used to be great, now it sucks.

KitKat didn't kill battery life. Mine is about the same as it was before KitKat. In about 99.999% of the time an app is to blame. I have a simple but arduous method to find the app that's killing your battery.

I agree the battery has taken a hit. I used to ave about 9hrs of screen on time, now about 6hrs. I also have the chromecast issue. Strange thing is that sometimes the screen doesnt even show up In the battery stats. Sometimes the usage time doesnt change when it shows in battery stats. I am stock, 32gb white US model updated with Kies. I have done many factory resets. I have tried it for 2 days without installing any apps or disabling any samsung bloat, with no change in the tablest behavior.

Kitkat sent my note into fits. Battery life was terribly erratic at first. Dropping 30% in an hour, then suddenly jumping back up by 10%.
I tried factory reset.... nothing changed. Then I used the Battery Callibration app from playstore. Ran it and followed instructions exactly. (Waited til it was charged 100%, then run the program, then completely drain battery, then let it charge continuously back up to 100%).
Go figure............ since then things have calmed down and I am getting the same battery life as on my old Jellybeans note. (I know, because I've got two of these tablets and literally compared them side by side.)
Or, it could also be that after firmware upgrade things need a bit of time to settle down. Hope this helps.

Yeah, I am used to android taking a bit to settle in. After my note 3 updated, it seems like it took a month to get back to my "normal". I hope the tablet does too, just frustrating in the mean time

Mine settled down after about 3 days and several resets. Now the battery seems comparable to pre-KitKat.

I don't think it is kit Kat. I'm running kit Kat and easily see 9 hours of screen on. It is most likely an app you have installed that is doing it.

Then not everyone would then mention that it is not change or improved (in stand-by).
No, normally a app or bad file on the sd-card is killing here the battery. All tools to find this out, are already mentioned here. Good luck.

4.4 in and of itself isn't causing poorer battery life. In fact, owners of other devices are reporting improvements. The Exynos N3 for example. There aren't any battery life issue threads on the Pro forums and they have the same h/w and we're most likely using their 4.4 drivers and kernel. There are threads like this in every device forum when an Android version upgrade is released. It's almost always due to a bad flash or a rogue app or service. That and older apps that haven't been updated in ions and aren't playing well with the new OS. People here have reported shorter charging time and longer battery life. So what's being discussed isn't universal. I'd suggest doing a stock recovery and reviewing older apps and those that aren't developed by known and larger developers.

I have a Shield and S4 too. For every poster raving, there seems an opposite view on battery life and the SD card issue.
The SD issue makes battery life debates moot. Google has an Apple wannabe syndrome. Perhaps they will rebrand as Goople.

You can recalibrate the battery by running it down below 20% then recharging. I have seen it recommended to do this every 30 days or so.
My Note 3 with KitKat started using 20-30% of the battery at night while it was idle. Looked and looked and couldn't find a clue to the problem. Decided to reboot, the next night it was fine, used maybe 2-3%

Agree and disagree!
I did have charging problem and battery drain right after KK update. I have to do the Factory Data Reset. Luckily my tablet is back to normal if not better. I did spend sometime go thru all setting. So I managed to get 4 hrs of screen time with moderate use and I still have about 59% of battery.
So I say kk is good or better then jellybean

Everybody wants to be a comedian.

I don't have this issue but maybe affected people should read this : http://forum.xda-developers.com/showpost.php?p=52366635&postcount=236

I updated a couple days ago and since then my battery just sucks. It just went from 100% to 29% in 2 hours just using Youtube. It can't be right. Definitely it's the upgrade!!
I loved my Note 10.1 2014 out the box that I decided not to root. So it's factory stock and suck very bad.
If it's a bad app I can find it. It worked flawlessly before the upgrade.

Factory reset and see if it still happens. A dirty flash can do weird stuff...

Yeah, im not getting great battery life either since this update. I just reset the tablet in the hope of tracking down what's the issue.
Troubling, since battery life was so great previously.

Abysmal Battery Life

Hey guys,
I've joined the club and bought an Axon 7 A2017G.
In my first 2 days of usage, I noticed I needed to charge the phone at least twice per day.
After reading quite a few threads about this issue, I installed GSam battery monitor. It lists my SOT as 1hr 13 minutes, and battery life at 10 hours.
At turning just about everything off, installing Greenify and applying aggressive doze, I was no longer getting a wakelock.
I have however found that GSam shows that my screen is discharging over twice as much battery power, as compared to having the screen on.
I was wondering if this was normal, and if not, any suggestions in increasing battery life?

Not normal try a reset.

Something keeping the phone awake, haven't used gsam in ages.. betterbatterystats is far superior in helping track down what's keeping it awake but requires root.

You can use this app to access original battery stat. Works very well.

I'll try that next. I've just completed a factory reset, so hopefully that helps out.
I found it quite strange that Screen Off used more power (52%) than Screen on (20%).
GSam didn't report any wakelock, and the phone was in doze quite often.

Seems that the factory reset has done the trick.
Now trickle re-installing apps.
Fingers crossed that battery usage stays relatively normal.

How's the battery performing now?
Mine seems mediocre. After charging overnight I usually need to charge in the evening. I get about 10hrs per charge with 2-2.5hrs SoT. Are you getting better results than this after the FR?
Thanks!

As GSam hasn't gotten all required data yet, I will go off what Android reports.
I have used 30% of my battery in 9 hours, with approximately the screen on for 3 hours. Bear in mind that I've had wifi on for approximately 5 hours with a mixture of screen on and off.
Just having a stab in the dark here, but, two apps that I haven't redownloaded are Swiftkey and Nova Launcher. Instead I installed GBoard and Google Launcher. Don't know if that had mde any difference.
So yes, far better results after the FR

Evie launcher FTW

I think it's time to reset! Those are much better results, kind of what I was hoping for when I got the A7

I also did the force update to B09 before the FR. According to ZTE it offers improved battery performance, but I didn't notice any improvement from B08, whilst I used it.
Good luck and I hope the battery sorts itself out

I was a little confused what you meant by B09 but I see you've got the A2017G. I'm on the A2017U so I think my equivalent update is the B29 which is what I'm on. I've got tons of apps to backup so I'm going to try resetting tonight. Think I might unlock the bootloader and consider rooting while I'm at it

I've been using cm13 and sometimes Android system drains too much, so I will go to TWRP and wipe dalvik cache and it greatly improves battery life. Takes 20 minutes, but is great for getting 5.5 hrs sot.

Nougat battery drain

Hi,
Am I th only one that is getting this ridiculous battery life. I am barely going over 2 hours of SOT and maybe 8 hours of battery with light/medium use. Clearly something is off. I did FDR and wiped cache.
Any ideas?

Are you using facebook/snapchat? Most likely reason, post screenshot of battery usage or no one will be able to help.

I do use facebook from time to time. I can't post yet unfortunately. Hopefully you can view the image I left a link for underneath my original message.

I use snapchat and facebook disabled. A bit drainy though even after f reset.

No issues here. Seems the same as MM to me. Maybe just a little more than normal. It was bad at first but began settling after a few days.

Few suggestions,
Firstly I did was install battery stats app and check if you can find whats eating batery
If that doesnt help I would say flash firmware with odin including data(Backup before this). After that do an Full Reset and then try.
Since This is complete OS upgrade it will help clean lots of things. I am getting 5-6hrs SOT. All the best

I had terrible battery life initially as well. So I did a factory reset and...battery life still sucked. I think that was because I allowed Samsung and Google to restore my apps and previous app data. So, I did another factory reset and a completely clean installation of all my apps (no Samsung or Google-assisted restoring of apps). Since then, battery has been back to normal, which for me is about 4 hours of SOT.

Same here. I did a clean app install also and that helped. The only thing I allowed to be restored was my gmail calendar and contacts.

Yeah my upgrade made my phone glitchy and half the battery life I used to get. But on the plus side my phone doesn't run as hot and lock up when downloading large torrents.

Did you guys flash with odin or did you OTA the N update? If you did OTA I would try totally wiping the phone (factory reset) and then Odin the latest N firmware. There are links for the N firmware in the guides and news section. I usually get 6 to 7.5 hours of SOT on N. I use T-Mobile firmware on my ATT device, wifi tethering works on the TMO firmware with the ATT unlimited data plan [emoji4]

Cmon dude, 6 to 7.5 hours sot? Seems a little far fetched... do you use an extended battery? Do you have a link to the specific setup that you use?

Guess I'm not good enough for a response since I'm just a "junior member" and all, lol... not sure what happened to my account, as i haven't been here for a bit, but I had alot of posts and such, my join date is 2011...

Everyone says I have a battery draining app and I know i do not as I had all the same apps when i first got this phone (ATT s7 FLAT) when the battery was great. The battery has been worse since the first update. I know batteries degrade but not this much. I factory reset and download all my apps again and for one or two days my battery is better. This phone either has a bad battery or the people working on the updates are just not caring as they just let the battery drain. Down to %50 after 30mins of screen usage of just Sync with reddit and 5 hours standby, Android System and OS are draining tons.

I noticed faster battery drain after upgrading to 7.0 but after agressively disabling unused apps with Package Disabler Pro and switching to a black wallpaper and lockscreen my battery life improved noticeably (as well as performance). But if you don't see any improvement with these tweaks then it is possible that you have a bad battery.

I've had an issue where I put my phone on vibrate and an hour later it goes back to sound and vibrate.

Oreo + stability update

Hi,
I have been using this phone for a year now. I really feel we got more preformance after oreo. The phone is pretty smooth after all the hassle. I do think we lost a bit screen on time with the os update. I feel that is many times the price of getting more speed. Anyway i tried for a while my G4 rooted + optimized. My conclusion is that optimized + sabs and non rooted s7 edge is really fast phone. I see no lag. I feel this phone has a year left in it and thats actually impressive knowing its 2,5 years old.
I tried Oreo without factory reset. My experience was that some of the apps did not function well. So i did the factory reset and all works now. I think its only smart move after os update. Now i will just clear system cache after minor fixes.
The last as good deal was lg g2 to me. Love your phone still its in the competition with never phones. After year i bet we see improvements that will make many of us consider changing to a next generation of phones.
Btw. Did anyone else get the stability update after oreo? What do you guys think of it? My feel is that now almost 100% is working and smooth as a butter.

You need to specify what version of the phone you actually have.

I have moved back to nougat and stayed there for now, i did not mind the cell drain as it still lasted me all day, however i had random reboots as soon as i moved to official Oreo or even custom rom with 8.0 base, did not matter what i did the reboots would get worse over time. I moved back to nougat and not one reboot experienced, Oreo for me is good when it worked and would love to use it but drove me crackers when rebooting. SM-G935F

This is actually intresting. My phone did random screen freeze and couple of reboots in nougat, but on Oreo that is not happening to me.
But i do definetly have the cell drain still after the last update. I kind of woke up by the fact that i have lost about 1h screen on time. Yes i am a heavy user so thats the first que for something is eating the battery.
What kind of cycle your battery lasts average and how is your SOT on nougat? My is average 27hours on time hours and sot 5-6 hours

I am unable to advise you on SOT as i don't monitor this, i am running a custom rom with nougat base (Sac23 S8 port) i have a battery life of between 29 and 32 hours, never really goes past 40% remaining at the end of the day.
