Lollipop update giving HORRIBLE battery life

Anyone else had this problem?
I installed the stock 5.0 update (G900FXXU1BNL9) on my SM-G900F and now the battery life is terrible. I'm lucky if I can get it to last until the end of the day. Today, it's dropped to 50% within 5 hours. Before the lollipop update (again, was on whatever the latest stock version was), my battery life was superb, lasting almost two days!
Anyone know how to resolve this?

battery life
I've had my phone off the charger for less than one hour and I'm already down to 90%. There's definitely something wrong because stock lollipop unroot was giving me much better battery life and performance.

Mine lasts about a day and tbh for a device with the specs of a low end PC with a HD display and constant internet connection thats about what id expect

When your battery lasts less than HALF the time of what it used to all because of one update, something is seriously wrong.

well mine lasts a day now and it did then. so either you need to factory wipe, or you need to look at apps you've installed thats not quite optimised for lollipop

Yup, factory reset solves battery drain after LP update, I was up to day 3 without charging this morning with still 18% battery left, but had to charge up as I was going out, reckon it would have lasted the rest of the day though

Got a reply off the Samsung Twitter team to do this, so now going to give it a go. Hopefully it'll sort it because the drain is driving me nuts

Without losing root?

Factory reset will lose root more than likely, almost certainly

It happened with me but after 2 days everything settled and battery lasts at least 12 hours but still less than kitkat.

I installed the update to lollipop..... After that indeed a horrible battery life. So I installed lollipop again using kies software......

Had same experience wipe and reload greatly helped. Supposed to be addressed in 5.1.

To add yet another subjective and anecdotal experience with the new S5 Lollipop update (on Verizon, in my case), I was seeing constant Wi-Fi disconnects (~5/minute) AND battery-life that went from ~15 hours to < 5 hours, until I turned off the "Smart Network Switch". Seems all the network switching was killing the battery as well. Did a FDR and it made no difference. As long as that feature is turned on, my Wi-Fi drops constantly and the phone heats up and the battery dies in a few hours, even without use.
Would be nice to know what I'm missing now that my phone is, apparently, using the Dumb Network Switch instead.

All you're missing now the phone is using the dumb network switch, is bad battery life, constant wifi disconnects, and headaches
I turned it off a while ago, and so have many more people I read about each day - it's supposed to keep you connected to the strongest signal, but in reality, it does the opposite, plus most people only have 1 wifi connection, so it's not necessary to smart switch - and even without it enabled, it will still connect to Data when it goes out of range of WiFi, so that switch is completely pointless to start with

Yeah, I kind of figured that. Sadly, I do have two wireless-access-points in my home to handle range-issues. I had not considered that this "feature" would have a bearing on the switching between them. I did test with one of them turned off, so I could eliminate that as a possible cause before I knew about this broken functionality, and it didn't matter of course.
Does it not seem a bit odd that testing didn't uncover that a Lollipop Galaxy S5, with Smart Network turned on, would kill the battery and render the Wi-Fi inoperable?
Oh well.

You could set up your two APs with the same SSID / Encryption key and have the phone switch seamlessly between them without smart network switch enabled

But yea, it seems that there are quite a few overlooked bugs with lollipop, 5.0.2 and 5.1 apparently address a lot of them, but when we get that update is anyones guess

Wrong section, all questions go in Q&A. Not general.

please note that there are some apps are working without permission like google music i think ,

I recommend you to stay in KitKat until Samsung Lollipop 5.1 firmware arrives. At the moment I'm using XtreStoLite ROM with Toiiki kernel and I'm getting am awesome battery life, about 8 hours of screen on, cheers.

My S5 is G900H and I have the same problem. I did not like lollypop

Battery drains very quickly

Hi all
I noticed that the battery runs out quickly.
It holds only 12 hours in normal use.
While I was at 48 hours with my Huawei mate 8
Is there a solution to this problem?
I have attached the phone version if it can help.

Wait bro, your firmware version is outdated, latest Lollipop firmware is 2.20.40.184, but yours is still running 2.20.40.90, update your firmware first then compare your battery stats from your previous firmware version.
How long is your SoT(Screen on Time)? Well, on a daily usage my Zenfone 2 lasts for up to 6hrs SoT(with wifi browsing, some gaming, 2g/3g texting including standby for almost 12hrs as well) so i think your experiencing average for this kind of handset.
Also note that you've posted on a wrong section, this thread should be posted on the "Q&A, Help, Troubleshooting section".

This phone generally has **** battery life for majority of people, there are every few people who see any decent battery life (like above). There are no solutions for good battery life for this phone.

I wouldn't recommend somebody (even less a new XDA user) to flash a beta firmware. Only the user itself should decide if he /she really wants to try beta software.

Comparing this phone's battery to a Huawei battery is like comparing a Prius to a Tesla. I can go 3 days on my Huawei Ascend Mate 2 but it's a 4000mAh battery and a Snapdragon chip compared to a 3000mAh battery and an Intel chip. The ZF2 battery will never get better unfortunately

I was getting some serious battery drainage on stock rom - I upgraded to the CM13 ROM with Android 6.0.1 - Set it on Root and installed Greenify + Xposed Framework - Smart Booster - Battery Doctor - Configured them all and keep my brightness on low when in doors and automatic when outside. My battery seems to be holding much better now. I haven't used that Stock rom Beta release of 6.0.1 yet so I'm not sure if that'll help. Good luck!
P.S - I only installed the mini version of GApps.

Check for the running apps and disable those that are not of use to you.. There are apps that run in the background, just run those that you think you will be using always.

Disable touch gestures, the ones that let's you double tap to wake it up, I disabled mine and during the night, with wifi on, it only used 1% battery.
Also, disabling LED notifications would help.
To replace the double tap to lock screen I use Greenify's widget, need to find a way to let me wake it up by volume buttons too.
Any other battery saving tips would be great.

But still, that's very good. I probably won't get this low because I have crappy reception at home, but I'll check it anyway.

zenfone 2 is best for performance lag free most of the time .....but battery life sucks.... and about that ferrari and prius thing... my friends sony xperia z series especialy z ultra has awesome battery life it is also quad core processor phone ...it is also a beast phone ...but there stamina mode saves a lot of battery ... 8 to 10 hr SOT is normal for z ultra..... so clearly power managment is very poor for zenfone 2. i am using marshmellow cm 13 .. greenify... .. overnight drop is 3 to 4 %... but as soon as i start using it battery starts to drain quickly..... i have searched whole xda forum.. but everybody is talking about wakelocks, thats fine but during actual use also it is consuming a lot of battery....i am tired of searching

SM-T715Y now receiving Marshmallow

So I just got the update notification on my 4G Tab S2 region code XID (Indonesia). F/W is on SamMobile as well, and would have installed it if my battery wasn't running low. Will report back soon!

so far it is exactly what I expected - GS7 software on a tablet. Great battery and none of the performance issues the first gen Tab S had when first receiving Lollipop.

Actually, battery life became worse on this update. I lose 1% of battery life in under 3 minutes without doing anything, my tab was just idle in the home screen.

But that didn't happen when I was still running Lollipop :/

I've noticed the battery drain too. It's not way worse, but it is slightly quicker at getting rid of charge. Has anyone noticed any other genuine changes? Apart from the lighter colour to the drop-down menu it seems basically identical.

Battery definitely drains faster in this update. It would take me 7-10mins for me to lose 1% of battery life in Lollipop. But now it would take me 3-5mins to lose 1% of battery life. I'm considering right now to go back to Lollipop to be honest, I can't stand this battery performance.
Other changes I've seen was the boot, it uses the S7 boot animation and there wasn't a boot startup sound.

Are many still waiting for the update?
Is everyone experiencing the rapid batter drain.
No update here.
Shofar

Charging time estimate seems to be gone from notif dropdown (no charging notif at all) and lock screen (just says charging, no more x hours x minutes until full)

Marshmallow works fine. The battery issues were and will always be there for first few days till the firmware settles in.
One problem i faced was not audio output on one of my bose earphones. I still get the output on an older pair. The new ones work fine with every other device including a note 5. Just not this tab. Any suggestions to make it work ?

Are there many of you still without MM?
More than a week and still nothing.
Is it simple to install from Sam Mobile?
Getting frustrated with Samsung.

Hopefully the battery issues are just temporary just like what you said, I am getting tired of this battery drain. This never existed in Lollipop.
About your earphones, maybe the Tab doesn't recognize it?

I guess I'll wait. Lollipop is not so bad....

Not to my knowledge. Dont have a microSD in my tab to test.

Still waiting
I upgraded from nexus 7 to the T715Y galaxy tab s2 8". Solid device, battery performance less than optimal, software updates non existant. The nexus still gets monthly security patching and got the android 6 OTA update in short order. Now 18 July and despite indonesia, panama, phillipines and other neighbours in asia having this update, still no word from Samsung. Tried Kies, side sync and OTA update button mashing... nothing.
In fact Kies said there was an update, which i installed, wiping my tablet to get .. you guessed it, the same darn version i had. 5.0.2. Would recommend the tablet if not for the lack of security and software updates.

Still waiting in Australia
Edit: finally got it about a week ago

Is this battery consumption normal?

Hi all,
I just come with this Screenshots to know your opinion on the consumption of my s5. Honestly Im jealous of those people getting 4,5hours of SOT in a full charge. I believe I can barely achieve 2h. My phone is rooted, de bloated with smart debloater and uses Greenify (which has not provided me a noticeable gain).
I've seen a very big drain just after plugging off the phone (like 5 or 6%) in two hours without using it. Also everything I unlock the phone the drain is very fast. So idle state seems no to be the cause
What are your thoughts? Thanks in advance.
By the way, while writing this post I've lost 5% of charge.

Need a new battery I think and with the battery you gotta keep it cool, don't charge you phone and use it when its under 20 ℅. And the hotter the battery gets the faster it will discharge and if your charging at the same time the CPU will work harder to charge the battery and do whatever you want to do with your phone making it a double whammy wearing out your battery much faster than normal. You not supposed to let our batteries to go below 20 %. Well you can but don't use it at the same time your charging.

Thank you very much for your information. Any suggestion about a new battery? I've seen this one.
I've just plugged off from 100% and I got a battery drain of 5% just by speaking 15 minutes (no hand-free). I think it's a very big battery drain for just a small talk. I think that confirm your hypothesis of the wasted battery.
Is there any way to know the real capacity of the battery I currently have? It is just to know how far it is from its original performance.

I've checked on Go Power Master app and it claims 2520 (at 90%) mah in my battery. Is this confident? If so, I shouldn't expect a big improvement buying a new battery. What about using other roms or making a factory reset?.

How old is your battery? Mah rating and the rate it discharges are different you can discharge 2600 mah batter in an hour or 3 days depending on use and environment and conditions. Like I said before the hotter your battery gets the faster the disharge go same with the cpu the hotter it gets the more power it demands from the battery. And if your battery get under 20% fast charging comes. Into play as well which is bad for the battery as well.
If your dropping off that fast I think is a defective battery or over clocked cpu settings. My s5 did he same till I bought a new battery I last 8-12 hours of heavy use now compared to 4 hours. With a new battery I suggest a higher capacity but same dimensions as the old one they can be expensive but a bigger battery will damage your phone over time.
I have a 5600mah battery now by 5he way.

Oh that battery looks OK I can't read the language lol just make sure its not refurbished or used and check out if u can refund it or not lol

My battery is from October 2015. It's the original one that came with the phone

Here is last report:
Despite performance is not the worst, do you think the difference with a new one is very big?

Back in my S3 Mini days I had to change the battery and the difference was huge for it. A year ago I replaced my S5's battery for the first time (I own my black beauty since february 2015) and I remember that I saw an improvement in battery life and in performance a bit as well.
A trick: take out your battery and put it on a flat surface (table or whatever) and try to spin it. If it spins freely, buy new one for sure.
I'd advise you to also update from KitKat to Marshmallow as that made my phone brand new but I see you're on 6.0.1 already so nevermind
I myself lose the first ~10% of my charge in one hour or even less...while not doing literally anything with my screen off. So yeah, maybe it's gonna be time for another replacement in a few months
By the way I tried Greenify today. The drain was far worse than when I didn't have it installed lol. Android Marshmallow is finally that one guy who's capable of handling himself alone without helpers like Greenify so try without it, it eats up your CPU anyway (as minimal as it can be, it still does).
With 3G always enabled I can get between 3 and 4 hours of screen on time (no games ofcourse) and around, idk, 10 hours total time until it hits below 10% and asks for some juice.
This^ was simply impossible with android 4.4.2 on the same phone so 6.0.1 really impressed me a lot as I had awful memories of Lollipop (that's why I didn't update for so long actually).
To sum up: try all the software ways of extending your battery life - with/without Greenify, uninstall/disable/optimise certain apps like Facebook and Spotify (says they slow down my phone), change ROMs, change kernels, change settings and if nothing works get a new battery.
PS: When Samsung go back on track and put a removable battery + all old features in a new flagship, I'm switching to that (S9, S10, SX, whatever xd). Newer phones got water cooling (~30 degrees while gaming, S5 gets 36-40C).

Thank you very much for your long answer. Honestly I don't trust too much battery savers. I've tried in the past many of them with no visible results. In fact greenify has never shown me any benefit. Notwithstanding, in this specific case, I've seen that hibernating "mi fit" (from xiaomi) I can appreciate a considerable improvement (5-10% of gain). I own a mi band and apart from keeping Bluetooth on (which seems not to be a big drainer) mi fit abuses of this connection. In fact "tools & mi band" seems to be more energy efficient with the connection to the mi band.
In any case I'll order a new one as it is not normal to have the drain for 100 to 90 being off and idle

I've changed old battery for a new one and I haven't seen any considerable improvement. After it, I've done a factory reset and a battery calibration (using the app on the store that requires root) and nothing... Any suggestion? I have the feeling that new battery is OK but somehow my phone is unable to take advantage of its performance...

Right now I have DreamUX V2 A7 (2017). I flashed one week ago hoping to remove this strange battery behavior. But it remains. Do you think reflashing stock firmware will fix it? I'll check instructions before going ahead. Thanks to both!

If it gets fixed after firmware reinstall then it's a software bug. If it gets fixed after changing the battery then it's a hardware bug. If it doesn't get fixed after trying both things then it's black magic :s
Also try to clear dalvik-cache and cache and do factory reset before and after flashing.

OK I'll go ahead with this. Good guide to reflash stock rom?
I'll do several factory resets to see if it helps, but I start to think that it's black magic

Sorry for the delay in replaying but I've made several attempts with not specially good results.
Now I'm getting 24 hours battery with 2h SOC for WhatsApp and browsing. Furthermore, I use Bluetooth for the miband.
The battery drop from 100 to 90 still remains. Maybe it's smoother but significant.
I've changed battery, changed roms (several times wiping everything). I've tried battery calibration app from rooted devices. I've tried the calibration procedure for non root devices (here I think I've obtained a little bit of improvement) but in general I have the feeling my phone is not detecting well the capacity of the battery (either new or old). Any tip? Advice?. Could it be the charging circuit? Can it be fixed? Should I keep doing calibrations more often to see if I grasp more capacity little by little?
Thanks for your time and help

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.
