Reading so many bad reviews of zenfone 2 batter life on this forum and e-commerce websites, I think the snapdragon based zenfones would be a better bet for those who are looking for better battery life and can live without top-notch performance. Eagerly waiting for the 3GB sd 615 based Zenfone Laser to be available. :)
[ZenFone 2 General] S#@DY:
The person has admitted that he just keep his phone screen on to record the screen on time. So that sot is of no use to us, because we know 8 hours is nearly to impossible with average usage
[ZenFone 2 General] ione2380:
Actually, zenfone 2 battery life is no worse than that of lg g4. Is in fact a little better. And is running way cooler than g4![emoji3]
[ZenFone 2 General] gontie:
The 550 ml should have much more since the resolution of the screen is lower...
[ZenFone 2 General] micnerd:
i d same problem with my battery usage(drainage).so i tried some changes and its 60% better now.

now im on superzen v19+linaro kernel v72 + essential debloater and also disabled power saver and auto start manager.

kernel settings are :

max frq:1333 on demand.cfq and sweep2sleep.

im using amplify powernap greenify for managing the draining apps.

here is how i made changes to the apps

better wifi settings [MENTION=6607081]kanagawaben[/MENTION]awaben

google...google set to no sync only when i need it tru clicking

location.....off

powersaver mode on the battery mode...3rd one.

wifi set to Never...on wifi setting....
[ZenFone 2 General] kanagawaben:
Even if you leave it in performance mode with always scanning toggled off, it turns on by itself again. I do not seem to be having any success keeping my WiFi off - "Better WiFi On Off" seemed to have done the trick, but today lo and behold my WiFi is back on (according to battery stats) and nothing I do seems to get it off.

[MENTION=6610671]pato2015[/MENTION] please tell me your exact settings for WiFi, location, Google, battery saver and Better WiFi On Off, so I can try the same and see if I can get it ti stay off.

There definitely are battery issues with the latest firmware -my wife also has a ZE550ML and is probably typical phone user (i.e. non tech-savy, doesn't root or tinker with settings, light to moderate use patterns) and yesterday she said "What is going on with my phone this week? The battery runs down fast every day even when I am not using it, and the phone is always warm." This corresponds exactly with her having taken the OTA. Looked at her battery stats and WiFi is always on and the phone has been almost permanently awake.

People have compared this to having an iphone, well it's way worse - I used iPhones for about 6 years, and while the battery was too small and SOT wasn't great, it slept like a dream, barely sipping power but still able to promptly and reliably receive mail, calls and other pushed communications. That was without having to change anything in settings. I know Android requires the user to be a bit more hands on, but present battery performance of this device is unacceptable. Thinking I may need to downgrade to an older firmware, which seemed more reliable to me.
[ZenFone 2 General] pato2015:
Ok buddy..ill check setting later my wife about to call tru viber..anyway my wifi totally off with better wifi...ill give other settings soon...

one more thing...try to install ampere from google play...during sleep my phone discharging at 40 to 60 mA...the power s low that why mines saves power...compare it to yours...you can see the power everytime you open phone see whats the mA on the notification area...the first one appears....
[ZenFone 2 General] kanagawaben:
Thanks for the info [MENTION=6610671]pato2015[/MENTION] I will give it a go and report back to you.
[ZenFone 2 General] kanagawaben:
[MENTION=6610671]pato2015[/MENTION] What do you set this one as? (Third one on power saver)
[ZenFone 2 General] pato2015:
Im using this latest build....

my power saving setting...

[MENTION=6607081]kanagawaben[/MENTION] do we have same build?... i dont use customized setting on power saver
[ZenFone 2 General] kanagawaben:
Ah, you are using the 82 beta firmware. I am on 41. Seems like they completely changed the power saver in yours. I will just leave it on performance mode I guess
[ZenFone 2 General] pato2015:
Proof of 7 hours sot :)

got to charge now...i hope this device gets more better on 5.1 version
[ZenFone 2 General] kanagawaben:
I thought I had it sorted, but now showing WiFi as on all the time again. I give up.
[ZenFone 2 General] pato2015:
Whats your wifi setting..? Is it ALWAYS ... wifi on always when sleeping?
[ZenFone 2 General] kanagawaben:
Here are my WiFi settings and Power Saver settings. I rooted and installed xposed in order to apply the patch for my data-only sim issues (mobile standby drain and the red bar all the time for mobile network). But after that it shows WiFi on all the time again. I turned off the patch module but still can't get WiFi to stay off. Maybe xposed is the problem now. I will wipe my phone and start again....
[ZenFone 2 General] ione2380:
The "wifi keep scanning" turns on by itself when: phone is plugged in for charge and when swiching between power modes. Otherwise it stays off. Today i put the phone to charge for a couple of minutes and when i removed the charger, "wifi keep scanning" was back to on. I think, this is a bug in the latest firmware as i never had it before.
[ZenFone 2 General] kanagawaben:
If you put power saver battery mode to smart saving and check the first box in the settings for that mode, it puts WiFi to never when sleeping and always scan seems to stay off. But still my WiFi is continually on according to the battery stats graph. I have had the same problem with earlier stock firmwares and also with CM. A quick google search suggests that it is a problem on a heap of other devices too on all versions of lollipop, seems to be a Lollipop bug that google can't or won't fix.
[ZenFone 2 General] ione2380:
[MENTION=6607081]kanagawaben[/MENTION], i don't have your problem. My wifi is off according to graphic. It's just annoying that i have to switch "allways scan", off everytime i unplug my Zen.

Later edit: olso happens when i reboot the phone.
[ZenFone 2 General] SBFarooq:
I honestly don't get what people are now saying about battery life... I used to get 3 hrs max sot but with the SuperZen r19 and TheSSJ kernel v75 I am hitting 5 hours sot with 22 hours off charging.. I have posted screenshots a couple of pages back... Really just keep things simple and IT WILL WORK..
[ZenFone 2 General] ione2380:
[MENTION=6641904]SBFarooq[/MENTION], not everybody is willing to use a custom kernel!
[ZenFone 2 General] SBFarooq:
if there is a great cure to your problem then why not use it to fix your problem.... God help me... I'm really stumped here..
[ZenFone 2 General] papped:
Custom kernel doesn't really fix the phone... You still get a ton of android OS battery drain, wakelocks, etc regardless of what kernel/cpu governor you are running. I've been running that kernel+rom for weeks and with thessjactive/yankactive/whatever governor i still get a wakelocks when the screen is not on for large durations of time. The battery life on this phone just isn't that good and a kernel isn't going to fix it. Especially compared to my mate 7, the battery life on this is terrible.
[ZenFone 2 General] SBFarooq:
Same here... BUT it really changed with the v75 kernel and the SuperZen r19 ... I am really enjoying my phone since then... Do review my previous post in this same thread for snapshots info...
[ZenFone 2 General] kanagawaben:
You shouldn't have to install a custom kernel and a customized rom just to get acceptable battery life. I was actually pretty satisfied with my battery until the latest update, but that has clearly broken something - the device just won't sleep properly now. Look at my battery graph here. I had just got up and the last section (charging spike) of the graph shows when the phone was on charge and doing nothing over night. Yet something has kept the phone awake the whole night. Never had this problem before. I was enjoying my device, but yesterday I basically wasted an entire day trying to deal with the WiFi and sleep wake problems.
[ZenFone 2 General] kanagawaben:
And yet since taking it off charge this morning, bizarrely it is sleeping perfectly and not showing a non-existant WiFi connection. Easily a day's use and about 5 hours SOT if it continues like this...
[ZenFone 2 General] papped:
Yeah it won't last... One issue i noticed is that the wifi always scanning likes to turn itself back on, particularly if you turn it off while wifi is also off, then you turn wifi on, it will re-enable the always scanning.... Seems like you have to disable it for both wifi off and wifi on, which makes no sense.
[ZenFone 2 General] kanagawaben:
If you set power saving like in these screenshots, then always scanning stays off. What the hell is the point of always scanning anyway!? Google always spying, more like. Anyway, the whole WiFi thing is a mystery to me - surely it doesn't need to be complicated - if I want WiFi I can turn it on, if I don't want WiFi I can turn it off. Simple, surely?
[ZenFone 2 General] papped:
It partly has to do with low power location acquisition without requiring the gps chip, but it's buggy so it's draining more power than it could possibly save right now... But yeah, it could be used for reporting statistics to Google as well.
[ZenFone 2 General] kanagawaben:
You weren't wrong. Once again, seems like something has started to keep the device permanently awake. At least for now, no WiFi activity showing.
[ZenFone 2 General] kanagawaben:
Is there some way to find out what exactly is waking/keeping awake the phone?
[ZenFone 2 General] papped:
You can try wakelock detector, you have to open the app and use the menu to convert it to a system app though.
[ZenFone 2 General] kanagawaben:
Wakelock detector didn't really give me any info I could act upon. I have now gone back to CM12.1, but the WiFi still shows up in battery stats when it is off. Did a *#*#4636#*#* diagnostic check and it reports WiFi as disabled but scanning???
[ZenFone 2 General] kanagawaben:
Screen:
[ZenFone 2 General] SBFarooq:
It's haunted?
[ZenFone 2 General] kanagawaben:
Seems like it :) but may have exorcised the ghosts - after a clean reinstall, taking the new OTA and being very careful in setting up the phone and installing apps, the WiFi now seems to be behaving itself. Touch wood it will stay that way.
[ZenFone 2 General] girishvk:
^ i had similar issue on a s4, where battery stats showed wifi on all the time (even when disabled).

i initially thought it was a display bug...:(.

After some tinkering, found there was a option enabled in wifi options(advanced options) where google was using wifi to scan for locations even when wifi was disabled. :|

after unchecking it, things went back to normal.

On my ZF2 however, the device behaves beautifully when asleep. i hardly lose over 2 to 4% overnight (idle).
[ZenFone 2 General] gontie:
4 hours SOT today with 90 minutes of MP3 on bluetooth and 25 minutes of Asphalt 8 gaming, it is decent.

Brightness was between average and low since there where not much sun today ;)

If i can have 5 hours of SOT with 90 minutes of MP3 on bluetooth and 30 minutes of heavy gaming (not angry birds i mean), then i will be really happy :)
[ZenFone 2 General] ione2380:
I uninstalled Asus boost, auto-start manager and Power saver. Wifi keep scanning bug is gone. And battery life seems to be better too.
[ZenFone 2 General] kanagawaben:
Good call. I have rooted and done the same (frozen, rather than completely uninstalled)

Wow got new settings and I'm discharging 18mA from 40 to 60 yesterday....its during sleep hahaha....ditch apps with ad links...installed battery bot pro ..lux.....and better wifi on off...from google...,:) and using no chromo as browser from XDA game apps...this totally ditch ads ...and low ram too
[ZenFone 2 General] kanagawaben:
Now sleeping perfectly. Only lost 4% overnight, predicted standby of 6 days :)
[ZenFone 2 General] pato2015:
Nice:)...I lost 2% lastnite from 12 am to 5 am...I'm too am surprised...I'll check again tonite ....to be sure.....
[ZenFone 2 General] ione2380:
If you have root, why don't you use adaway to get rid of the ads, system wide?
[ZenFone 2 General] pato2015:
Don't wanna root until I get 5.1.1....as I'm using 550ml..on asus beta program...never been rooted...pure stock.....wanna experience this first unrooted thing ....
[ZenFone 2 General] kanagawaben:
Well, sweet sleep and no ghost WiFi was nice, but seems like none of my Line messages or 050 Plus IP calls were coming through when the phone was asleep. I have unfrozen boost, auto-start manager and power saver. Allowed all apps to autostart and put phone in performance mode and turned on the WiFi always when sleeping and WiFi always scanning. Let's see how it goes if I embrace the full power of my phone :) maybe it will miraculously all be OK. Or maybe I will need to stay near a power point...

Since I'm not rooted..I seen a fast decline of my battery when in use when auto start manager disabled...darn have to able auto start manager.again...disabling this really suited for rooted device....grrrr.:)
[ZenFone 2 General] mickey36736:
Since I updated to V 40.63 battery seem to be better. 5 hours standby lost 3%.

No xposed for now. Only root.
[ZenFone 2 General] Kaleidosc0pe:
The discussion is very interesting for me. Thanks everybody.
[ZenFone 2 General] kanagawaben:
Yes, 43 (550 version of 63) seems better than 41 for me. Even though I have put everything on, as I explained earlier, the battery performance seems OK. Looking at the graph, there is nothing out of the ordinary. I can enjoy my phone like this.
[ZenFone 2 General] TC93:
Is it this bad even with a custom rom?

I currently just received this phone and the battery is awful. I am running the stock rom, but I turned off everything mostly, including gmail syncing. Yet I still lose 2% battery power every hour when its sitting idle, doing nothing. Is this normal?

My LG G2 phone loses between 0.3 to 0.5 percent per hour idle, even on lollipop 5.0. I test it with the "My Battery Drain Analyser" app which displays how much per hour it drops.

I'm tempted to return the phone. I bought it from Newegg which has a no return policy, but think I can still return it to American Express card through their return protection. I like everything else about the phone though.
[ZenFone 2 General] Siddk007:
yes my dear friend, everything about this phone is awesome except battery backup. also it becomes worse after every ota update. battery % just keeps dropping while normal usage. even tried custom roms and custom kernels too. also every app that can save the battery drop but no success. i dont feel like i'm using a 3000mah battery. worst battery backup. max SOT is 4-5hrs. right now on stock rom v2.20.40.43 ze550ml
[ZenFone 2 General] TC93:
Using the cpuz app, I notice that while the phone is on and not really doing anything, all four cores of the Zenfone 2 are in use, and each at 500mhz, never going lower.

But on my LG 2 phone which also has four cores, only one core is active, the other three are stopped, and that one core is only at 300mhz.

It would not surprise me if the Zenfone 2 is running all four cores when the phone is off in standby also.

---------- Post added at 06:03 PM ---------- Previous post was at 06:00 PM ----------

I should add that I have the 2gb ram, 16gb storage, U.S. model, I think the 551ml.
[ZenFone 2 General] pato2015:
There's a bug right now...WiFi scanning automatically turns on...this drains battery a lot...

---------- Post added at 11:35 PM ---------- Previous post was at 11:30 PM ----------

Yes i confirm..lost 2% only during sleep from 11pm to 6am....yezzzzz:)...Playstore and google service on.....but the problem is when in use...
[ZenFone 2 General] kanagawaben:
4 to 5 hours SOT with a day's use is not that terrible, surely?

Having decided to embrace the WiFi scanning while WiFi is off function (since it kept turning on anyway), it really isn't that bad. Whereas before my WiFi was getting stuck on scanning almost permanently, after a clean install of .43 with WiFi scanning toggled on in high performance battery mode, it seems to just scan the WiFi for a split second occasionally (presumably working as intended) with no impact real on battery. Also, having allowed all apps to auto-start I actually seem to have fewer wakelocks when the phone is sleeping. Doesn't seem to make any difference to my available RAM either. I guess that basically ASUS' attempts at battery management just cause issues and make things worse, so you are actually better just turning them off or setting them at maximum performance levels.
[ZenFone 2 General] kanagawaben:
Here's a screenshot showing the minimal WiFi scans:
[ZenFone 2 General] SBFarooq:
Getting 5 hours SOT during the day .14 hours off charger .not bad at all...
[ZenFone 2 General] kanagawaben:
551 or 550? I get about the same on my 550. It's decent.

But, since yesterday afternoon my WiFi ghost is back permanently :( Not sure if it affects battery or if it is just a reporting bug (but suspect the later, as a *#*#4636#*#* diagnostic check says WiFi disabled and supplicant state disconnected). Still, drives me to distraction. Somebody shoot me! ;)
[ZenFone 2 General] TC93:
Well all I can say is that my phone is brand new, with nothing else installed except the latest updates. 2% battery drain per hour, when in sleep mode is unacceptable. I find it hard to believe that wifi would cause that kind of constant power drain unless its downloading something. My LG G2 also has the wifi on in standby. The only reason I got another phone was due to voice quality problems on my G2.

I would bet its their cpu use that is causing it. Never shutting cores down to zero will cause a big drain on the battery. I have no way of checking it, but I would bet those cpu cores are still all running in standby. Its a constant drain too because its almost always 2% per hour.
[ZenFone 2 General] kanagawaben:
And yet other people are getting drain of only a few percent overnight. It is strange how inconsistent the battery performance can be.
[ZenFone 2 General] SBFarooq:
551, and are you on stock? If so then try SuperZen... Coz I don't have the Wi-Fi issue..
[ZenFone 2 General] kanagawaben:
Stock, have just installed the lite version (similar to superzen)
[ZenFone 2 General] pato2015:
Proof of only 2 % battery drain overnite.....straightline in the middle.....
[ZenFone 2 General] neko95:
> tried to install ampere and found that mine is no in minimum of -100 ampere in deep sleep.
[ZenFone 2 General] kanagawaben:
Something is causing real inconsistent battery issues for my wife's 550 on the current .43 firmware. One day it will be OK, like yesterday when it lasted her all day no problem. But another day it will stay awake all the time and get warm even though nothing is running and screen is off. Two days ago it lost over 10% battery in about 30 minutes after coming off charge in the morning, and she texted me in the afternoon to say it was down below 30% in the afternoon even though she had barely used it.

I got irritated with the bug with WiFi scanning always coming on by itself on mine, and the mess that ASUS have made of auto-start manager and power saver. I just couldn't get it to consistently sleep properly and still receive all my messages and IP calls. So I have gone back to running CM12.1 instead of stock. CM is not a battery stamina star either, but seems more stable, reliable and predictable regarding battery use than stock. Asleep it drains a bit faster than stock (when that sleeps right) but not at an unacceptable rate. Drain while in use seems similar to stock, perhaps a bit better now that I have parked a couple of cores and reduced the maximum clock via Kernel Auditor. And most importantly, all my communications are being received promptly and reliably. So for now CM > stock for me.
[ZenFone 2 General] pato2015:
....

So some of your apps are active during sleep then....do you have a tasker? I disabled google app...mine sleep at -30 MA...no root...
[ZenFone 2 General] Dan_Jacques:
The lower frequency is 500MHz, without hotplug when screen is on, in the stock kernel.

With Project T, the lower frequency can drop to 333MHz on the experimental version.
[Nexus Player Q&A, Help & Troubleshooting] ghtop:
Saving WiFi passwords to your Google account is a standard feature of Google's Backup & Restore, if you have this enabled. The option to disable this doesn't seem to be exposed by the Android TV UI, though.

And that support conversation was hilarious :)
[Nexus Player Q&A, Help & Troubleshooting] nharish77:
That is precisely my point as well. When information that pertains to me is stored, I need to have the option (within reason) of being able to delete it. When such an option is being provided on their Android devices, they only have 2 options on the Nexus player. Save it on the device and a factory reset removes it OR allow the option to delete such info. Not doing either seems like a violation IMO.
[Nexus Player Q&A, Help & Troubleshooting] PhyerFly:
I've been looking for a way to solve this exact problem.

I have a 5ghz SSID and a 2.4ghz SSID and I want my nexus player to ALWAYS use the 5ghz, but because I have the same Google account synced to all my Android devices I can never "forget" the 2.4ghz SSID on my nexus player, it always gets restored. To make matters worse, the nexus player prefers the 2.4ghz connection because the signal tends to be stronger.

The only solution I've seen is to dump and disable android backup on every android device I own (2x Nexus Player, 2x Tablets, 3 Phones) to prevent it from syncing both network connections, but it doesn't appear to be possible to JUST remove wifi networks from being synced.
[Nexus Player Q&A, Help & Troubleshooting] Haggster66:
Intersting to read that. Do you at least have a reliable connection when using the 5GHz? (meaning a stable connection over a full week, without connection drops?)

By the way: If *anybody* could shed some light on whether the Marshmallow preview finally enables us to use DFS channels on the Nexus Player, then this would be great. I cannot really flash the preview as it would wipe the player and I'd need hours to set up all my apps again from scratch... and since I know that some people have been testing this, I prefer to ask. Apparently got new neighbors last week who are now polluting the lower 5GHz band which used to be perfectly free... so I wanna switch to the DFS channel frequencies, however the Nexus Player can only connect to the lowest four 5GHz currently, which are the non-DFS ones (all my laptops and even a friend's Samsung tablet from 2013 support the 5GHz DFS channels though)
