Accurate battery life?

Just got a new Z3 D6616. This is the battery life projection I'm getting. I bought this phone because I heard great things about it's battery life. Also, when I saw a YouTube review, the guy's phone had a battery life projection of several days. Is something faulty with this specific handset? Am I doing something terribly wrong? Please advise.
PS. I'm at about 30-40% screen brightness with the adaptive setting on.

You should actually use the phone from 100% doing your daily stuff till about 1% and take screen of your on screen time. On screen time is what matter. They claimed to have at least 8 hours SoT with normal usage but the max I can get is only 4.5 or 5 hours.

I did a lot of reading before buying the phone. Heard about the "memory" screen or something that helps towards battery life. Several users claimed 10 hours SOT. Could it be the newer firmware that might have reduced it? I'll post the YouTube videos I saw shortly.

I use brightness at about 1/3 and have location and autosync on. I get about 8-9 Hrs SOT in a 36Hrs period.
At first even I got 4-6 Hrs SOT until it calibrated over a few charge/discharge cycles.
It takes a few cycles for the battery to calibrate, if you want to do that faster do the following:
1. Drain to 0-1% with normal use
2. Do a full charge till 100%
3. Do another full discharge (Dont charge in between)
4. Do another full charge till 100%
5. Now just use it how you want.

Thanks! Guess I'll have to report back report back after a couple cycles.

I have the same problem, I have enable the stamina mode, have the brightness at half and auto,and the battery won't last for one day,as an example today when I get up after I unplug the device it go from 100% to 99% right away and now after 10 hours without game,photos just Internet reading over WiFi the battery is at 31%. It doesn't seem normal, what should I do?must go to service?

I'm at 59% and my phone predicts 1 day remaining.
D6616 as well
I do suspect an app draining my battery though...

1 day standby time you mean?

Nope, 1 day 19 hours standby
Well, it says 23 hours now... and 1 day 18 hours in Standby mode.
I also have no power saving features enabled, with max brightness..
I can get 6+ hours if I limit my brightness, but I settle for less with max brightness throughout the day.

Could it have something to do with the display image enhancement mode? I'm using X-reality. What about you?

I have it turned off, I can't really tell a difference..
Sometimes my "battery forecast" is low like yours though, I wouldn't worry about it unless you're actually getting bad battery life.

The battery life I'm experiencing is worse than the "forecast", which is essentially what worries me. Regardless, I've no right to whine unless I've cycled the battery completely at least once since it is after all a brand spanking new phone.

I doubt I'd get the 24 hours from now with my current use either. As long as it lasts me throughout the day I'm fine.
I can generally go the entire weekend without charging my phone though.

Ive gone through 3 Z4s (Cosmetic defects/lightbleed) on my 4th Z4, all of the were bad until they were calibrated within a few days.

Lol yes.

I fully discharged and recharged my phone. Now I got 18 hours usage, including 7 hours SOT with the screen on max brightness for half an hour. It's getting much better now, certainly a huge improvement over my previous phone!
Sent from the inner sanctum of my mind.

That's more like it, it should get a little better.

Please have a look towards the end... My phone's been awake when I was asleep. Is there an issue with this phone deep sleeping? While I get a good SOT, the idle drain is too high! Please advise on how I could investigate if a particular app is doing this. I used to use "wakelock detector" but that no longer works without root.
EDIT: Stamina Mode always on.

I have the same problem too... Whenever I leave the phone idle, even with the stamina mode on, it still uses the battery as if I was using it.

Battery Problem

Hey Guys
i have a strange Problem
my last one plus one had a good battery life time but the sound buttons get brocken , so one plus change my mobile.
1 wekk ago i get my new phone, everything is working but the battery drain was very fast.
i decided to install blisspop with bueffola kernel tweaked it a little bit for battery saving and install BBS for wakelock detections.
I elimenate all the wakelocks that cause a fast battery drain and since that te battery drain in idle is minimal but when my mobile phone is on the battery drains 3% in 1 hour.
That's weird cause as i say i eliminate all the wakelocks that causes fast drains and use the phone most time for spotify and whatsapp.
And if i start to browse on the Internet the battery life drops even faster
So what can i do?
Am i do something wrong
or is the battery of this new phone crap and i'm so luckily to get a phone with a failiure battery?
Any suggestions would be nice and sorry for my bad english.
German or russian is better

on 50% battery i have something like 2h of screentime so i thing till 0% battery i will have 4h SOT and this is nothing (don't use the Phone much a saing above only whatsapp and spotify)

Well, to be honest, 13% in 4:30h is not "very fast" considering you had 30 minutes of screen time. Mine loses about 10% per 30 minutes of using the device, going by that there are only 3% unaccounted for which easily fit the 4h standby your device was in.
Anyway. In 4:20h of tracked time, you have 1h awake time of which you had 35min of screen time. The remaining 25 minutes can be split up in roughly 15min of AudioOutput and 10min for several wakelocks such as the proximity sensor doing stuff for 3 minutes, the phone doing stuff for 4 minutes, basically everything is accounted for. All in order I'd say.
What I spotted:
You are on Lollipop. Did you wipe after/before upgrading to Lollipop or did you dirty flash from CM11s?
Do you have the new Lollipop-compatible firmwares (they come with CM12) installed? Not sure they come with Blisspop.
BetterBatteryStats has the CPU sitting on 1500MHz for half an hour. Check whether you configured your system to stay at 1500MHz with screen on which of course would be crap, the CPU should idle at around 300MHz.
It seems you had the device shut-down and then booted. Booting up the device eats massive amounts of juice.
Android reckons 3 days of usage like that, what's not ok with that?

1. Yes i wiped it and don't dirty flash the rom befor i was going to lollipop
2. Not sure have the latest bissplop
3 Where can i check what i configured to stay at 1500MHZ , in the kernel settings?
4. i know i rebootet it once
5. The reckons of the 3 days is not true , it only affects if my device is staying in standy cause i lost nearly nothing (as you will see in the logs i posted in the spoiler.)
The first BBS log shows the Device fully charged at 100% with wifi and Mobile Data on. I left the Phone in standby for the night (8h) and i didn't lose any precent.
So after 8h standby i still have 100%
After 11 o'clock till now i used the Phone mostly for spotify , a few times Whatsapp and something like 30-50min for internet.
In the second BBS log you will see that i lost Bat.: -35%(88% to 53%) [4,5%/h] although the SOT time is only at something like 2h.
The SOT time of 4h would be total normally for me if my reckon of android would be 3 days cause this is the case on my lg g2.
Because i use the phone most of the really only for spotify.
So the main problem of my device is not the idle drain but the drain if the screen is on or spotify works in the background with screen of.
I hope that the BBS logs in the Attachment and the 3 pictures can help you.
Thanks for your help

Don't go by the sudden drop of battery percentage after staying in standby for a long time, eg. over night. The very subtle decline of the voltage over the course of the night is smoothed out and reported as 0% lost. Once you start using the device, and the change in voltage gets more noticeable, the situation is re-evaluated and the previous drop of 0% gets counted in and a sudden drop of several % over a short amount of time will occur. This is physics and by design.
As for the rest, I'm by no means a pro in reading BBS Logs but from what I see, yes you are on Lollipop firmwares/baseband so we're good. The device enters deep sleep just fine, excellent in fact. No major or irregular wakelocks seem to occur, perfect.
As for the daily usage log, I see 7:45h. Of which 4:10h in deep sleep and 3:35h awake, of which ~2h screen on and ~30min phone on. You lost 35% in that time, averages 4.5% per hour. This seems perfectly ok. This would translate to 7h awake time with 4h screen time. I seem to fail to see your problem.
Interestingly the frequency tops now at 1500MHz. Did you change something?
To take myself as an example, on my way to work, I lost 19% in roughly 45-50 minutes of playing ingress. I had about 45 minutes of screen time, GPS constantly active and of course constant data traffic. I arrived 2h ago, barely touched my device in those 2h and lost another 2%. This is more or less in line with your usage, 1-2% when sleeping, 4% when awake with screen off, ~20% with screen on. You're not happy? You reckon you had more on your previous device?

Thanks for reply and help
My goal is to have a few days with android e.g 2-3 days
SOT is not so important.
Important is that there is not hudge battery drain wenn i hear spotify cause it dosn't mather if the screen is on or off it drains hard
On my lg g2 it's not so hard
And no didn't change anything about 1500MHZ
Any suggestion ?
Greetings

How's your battery life

I love everything about this phone but the battery . Im hoping to get 2hrs of screen on time . Anyone else have issues with the battery. Any tips would be appreciated.

Try turning off the Always Scanning for WiFi option. Also, change the Sync settings for apps you don't need to be synced at all times. And Location setting to Battery Saver.

When im at home i can pull close to 4hrs screen on . If im not on wifi the phone idle is terrible. I probably drain 6% or more per hr idling. Its hard coming from a note 4 , but i guess it is what it is.

Draining at 6% per hour is not good & unusual. But for Android 5.0.2, it seems about right, unfortunately. My N5 drained at that rate before the 5.1 update.
On my S4 with its 2-yr old battery, I drain at 3 to 3.5% per hour on idle with both WiFi & LTE turned off.
On my N5 with a new battery & 5.1, I idle drain at 0.7 to 1.5% per hour.
I'll add my battery drain rate once I get my S6E tomorrow.

This is mine on light usage. I noticed etter after a factory reset. Heavy usage is between 6 and 8 depending on wifi

I'm debating going to get one of these... My Note 2 keeps not charging and the stock battery died in 1:10 (from 50% to 1%) during a run yesterday. I was using spotify and mapmyrun.

Today is my first day after first full charge and my battery drains at ~3.5% hour, per GSAM.
I have screen brightness at little bit below the half-way mark with Auto Brightness checked.
I disconnected my phone at 6 AM and right now, it has been on 16 hrs 30 mins. I have gotten 2 hrs 30 mins SOT with 45% left.
Wifi active for 6 hrs, LTE for about 1 hr.
Screen has used 52% of my battery, Wifi 15% (5.0.2 shortcoming), Bluetooth (2%), Held Awake (0%), Phone (0%), Phone Radio (0%), App Usage (31%).
So far, the S6E is outperforming my Nexus 5 on 5.1 with a brand-new battery I swapped in on 4/1/2015.
Happy with the S6E's battery life, especially considering it's only 2600mah.

a little over 6hrs and it went from 100% to 14%. Granted 56%-23% were on a 1:43 run using Bluetooth headphones + spotify and mapmyrun mapping my way. Oddly, when I look at the battery usage, OneDrive is at 18%!

18 hrs & 37 mins off the charger with 4 hrs 8 mins of SOT. 17% battery left. I'm very happy with this. Update to 5.1 should improve it a lot more as it did on my Nexus 5.
Android System & Kernel battery usage is pretty decent. Those two on my N5 on 5.1 drains way more battery than it does on my S6 Edge.
When I'm not actively using my phone, the idle battery drain rate is pretty good - 1.9%/hour (similar to my N5, with the N5 being a bit better).
13 hrs & 9 mins off the charger with 2 hrs 20 mins SOT --> 52% battery left.
All this is without Root and my usual battery-saving Root programs.
Once 5.1 rolls out and if I decide to Root the phone and add battery-saving Root apps, I'm expecting to achieve 6-7 hrs SOT.​

Ive noticed that turning off location and disabling google now has helped my battery life a lot.

I love this phone, but the battery life is the one terrible thing. 7-10 hours seems to be the max. I might have to return it and suffer the summer until the note 5.

i'm surprised to hear about all the negative battery life issues on this phone. on my GS3, i'd lose 3-4% battery just driving to work - now I get there and still have 100%. maybe i'm just not as heavy a user, but the other day my phone was off the charger for 16 hours and I still had 43% when I got home - and that included using Google Maps for 20 minutes, texting throughout the day, and using a bunch of apps. when idle, I generally only get 1% battery drain. my only complaint about the phone is some of the UI that I can't customize, but it's only a matter of time before custom ROMs are available...

I lose 10% or more battery on the phone regardless if I'm using it or it is sitting with the screen off. When I drive the 45 minutes to work, the battery is at 89%-93%.
A 1hr run with it on my arm playing spotify/mapmyrun seems to use about 26%.
Basically, I'm always worried now about the battery dying when I'm using it.
at the end of next month, I have a 14hr+ a day for 4 days music festival where I can only charge it at night. 7-10hr battery isn't going to work for me. It seems bizarre to me that they made the best phone ever, but skimped on the battery.

drive to work today with the phone just sitting beside me, 100% to 86%.

Is your location on? I had to disable google now. Turned off nfc, advanced wifi scanning.

my battery sucks too :/
i live by the charger even more

with all the same activities that got 7-10 hours on my Edge, the Note 4 is getting 14-24hrs.

Battery is beyond horrible!
Wifi is off
NFC is off
What else can I turn off? I can't even get half day out of this POS.

I think you actually want Wi-Fi to be on. I find that on any android device I burn more battery when using cellular networks.

I'm getting desperate with the whole battery situation

So I had the S6 last year and ended up returning it due to the poor battery performance. I ended up back on an iPhone. When the news of a larger battery and better chip performance come out for the S7 I was ready to jump back on the ANdroid bandwagon.
So fast forward. I just unplugged my phone at 100%. It's been a half hour and I'm already at 95%. I have to consistently keep the power save mode on to conserve battery. It's getting somewhat annoying because it screws up updates and notifications as well as some app don't work well.
I've tried conserving battery by shutting off certain features, keeping display brightness down etc while having power save mode off. It just seems that Android System is chewing through the battery. I don't know what the hell is doing it either.
I don't want to cripple the phone by keeping it on power save mode all the time. Does anyone have any recommendations that will help me or I might have to return this phone and ALL the free stuff I got with it.
Thanks

Half hour of use at 95%? Cus that's not bad at all. I'm consistently getting 5-7 hours of SoT.

I think OP meant half hour of standby because im experiencing the same type of battery drain. But even with this drain im getting about 10-12 hrs of moderate use with 4.5 hrs SoT

Turn AOD off. Let the battery run down... Turn off fast charge. Fully charged the phone. Don't disable anything else. Go through a couple cycles like this. You'll see a difference. Then use package Disabler pro and disable what you don't use. You'll be happy...

So for the hell of it I turned off location in the drop down menu so see how it affects battery life. I have been off the charger for about 2.5 hours now. I have used the phone here and there throughout that time. When it came off the charger it was at 98% and it's at 91% now.
That's 7 percent with use in 2.5 hours whereas before it lost 5% in a half hour on standby with no use.
What the hell is pinging location over and over? If you hold down the location drop down menu option the phone displays the apps that use location. All of them say low battery use.
Is there a way to set these up to only use location when the app is being used?

Is fast charge bad for the battery or something? I've gone through about 3 cycles with fast charge on and battery still isn't great. Hoping it will improve after about 3-4 more cycles

All I know is that it made a huge difference for me. I think that it's more of a battery calibration thing. It really doesn't take that much longer to charge the phone with fast charge off...

Battery life, how is your phone doing?

Wondering how is your battery life, I'm 5:30 hours for 54% of battery(75% - 21%)
I max charge it to 75% and usually I don't drain it less than 25% - To achieve the best battery life long term, so I won't need replacement anytime soon. Also I don't fast charge, usually 1A charging or similar(e.g. Wireless charging 7.5W)
Obviously I use underclocking to the point I don't fee any difference in daily usage
Share your thoughts, for 0-100% I bet I can do more than 7:30 SOT

Lol mate you're more like 5:30 min after 75-25 twice.
Such a bad battery life usually happens after using mokee as they change low lever instructions in the processor.
What happens is that the processor microcode is changed such that instead of power being managed by the relative motion of conductors and fluxes, it’s actually now managed by the modial interaction of adreno-reluctance and capacitive directance of the cores. You can not change that any more as it was a change on hardware level microconductions that can not be reverted.

50%(75-25% usage) of battery gives me 5:30 SOT hours and it's bad?
You troll right? this is only achieved with underclocking, at 100% you should expect more than 7:30 and maybe 8 hours! what about you?
P.S. Give me your SOT 75-25% and if it's more than 5:30 SOT I'll send you my phone for free - Bet you can't even do 6 hours SOT with full battery

just look at the screenshot you provided yourself, the battery graph clearly shows you charged your phone after you hit 25% the first time to 75% and let it run down to 21% again. battery (and sot) stats won't reset until you charge over 90%, so your reading of 5.5 hours of sot is actually 2 instances of your habitual 75-25% drain. in reality you are only getting about half that for 50% use (~2h 45min sot), which I'd say isn't too bad, but maybe you should do a full 100% to 0% use once and see how the battery fares for a more accurate reading. honestly I would say you would still get around 5.5-6 hours sot from that, and that unless you do some serious tweaking to both your phone and usage patterns you wouldn't be able to hit 7 hours sot, but I would be willing to see evidence that proves me otherwise.

Battery Charge Limit - Resets your stats but also limits the charging
I know you are clueless but talking without knowing is bad - 5.5 is for 50% battery due to high underclocking I've got
With 100% I can get over 8-10 hours - High end CPU cores are not more than 1.5Ghz, gpu at power saving but also lowest possible freq for min/max - You are talking crap but ok I won't feed you, I stop feeding trolls the moment I get they troll

sorry but you are the one talking crap, please see attached picture, which is a crop of your battery graph. i personally also use the battery charge limit app, and i know how the reset battery stats option in the app works, which will clear the battery graph as well. if you really did clear battery stats you wouldn't be able to see this upward curve.
how about this, you fully charge your phone and use it normally until you hit your claimed 8-10h sot. honestly i think i can match your sot, but without this underclocking you highly praise.

You're either braindamaged or a troll. You charged your phone and it didn't reset stats so it combined both usages. Did you pass 6th grade maths? Anyways SoT is subjective and you're just being extra petty about this

Only 10?
By doing a small mod on the battery, I get like 12 hours minimum, with 50% brightness fixed. What I did is that I replaced the main-winding of the normal Lotus-O-Deltoid type and placed it in the pan-indermic semi-boloid slots of the battery.

Removed lots of bloatware using adbFastboot tool and connected mostly on wifi. Without wifi with medium usage, I can get around 6 hours SOT within 2 days of use.

aex + canting.

I've had mine for 18 months and am still very pleased on the charge. I can typically get 12 - 14 hours fine, and that does me for most uses. I've seen it go longer when I've used it less (for example right now 20 hours without charge - 6% left, although that would include about 7 hours of sleep so no use in that time).
No modifications on my part.
