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...

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.

I think you mean Z3s...

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.

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Google Pixel XL's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

Hi everyone.
Is it normal standby drain for 5 hours 14% AlwaysOnDisplay Off, 20% AOD on?
Android Pie. Pixel XL.

That's not normal. Normal should be around 2% lost.

Since I'm on Pie (beta and stable), the drain, with or without, Wifi On and Mobile On, it's been very high!!!

well, I have to correct my statement. If I turn off wifi and mobile data, standby drain is stellar!!! During the night, I can get no more than 3%
Can't say the high drain that I have if using the phone... something that got a lot worse after a year (when I got the phone)

When my pixel xl is in standby for 3 hours, my battery drains arround 15 -17%, and my phone always shows Charging Connected Device via USB notification like it is charging another device, even when isnt connected to charger.

I'm getting between 1.5% and 2% per hour drain while idle at night doing nothing, since Pie. OS doesn't report any errant apps. Greenify isn't griping.

It almost uses no battery in standby! It's like magic. In one night it may lose 1% if you leave it on.

although i get about 2 and a half hour screen on time, i get virtually no standby drain whatsoever (latest stock pie). went to bed last night at 39%, *10 hour sleep*, woke up at 38%. what i dont seem to get very often is notfications while i am sleeping until i use my phone again in the morning, something to do with adaptive battery or doze?

are you guys leaving the phone connected to a Wifi?
do you guys disable LTE/Data connection while on wifi on Dev Options?

i always have WiFi and LTE enabled. Unless i want to use LTE instead of WiFi, then WiFi gets disabled.

I have a massive drain and phone gets hot lately even on stanby, i don't know what happened, didn't add any new app, still on pie.

Hi ramheer
Do you agree with devsk assessment of the AOD that the battery drains at approximately 2% per hour with it on?
Not sure if he has it always on or just motion like yourself...

I've just started to use the phone after all the set up and transferring sim over and I started with 100/99% before bed and it drained 10%.
Maybe I need to let the battery settle and try without the AOD tonight as a test.

Every AOD implementation drains ~1% battery per hour, but the problem here is that this device has LCD screen, which increases the drain.
I have a device with AMOLED screen and I get around 7%-8% battery drain overnight with AOD enabled, so I just decided to disabled it most of the time and just enable it at certain hours.
I saw the U11+ has an option for motion, so maybe you should try that.

Not impressive, I lose about 1% every 30 min without using the phone :/ (Exynos)

This is pretty disappointing it looses 10 - 15% of battery overnight doing absolutely nothing.

I am losing about 2%/hour doing absolutely nothing.

My S10e loses almost nothing if I turn things off.
Airplane overnight = less than 1 percent
with AOD it loses a bit, 4-5

Excuse me guys, but its not true that the phone does nothing. It communicates permanently with the antenna signals and the network, so its absolutely normal that it drains battery. Every phone drains battery in standby, even when they are on airplane mode (although in this mode the drainage is much much lower)
If you want yout phone to actually do nothing, you have to turn it off.

Yea... no. My two year old Oneplus 5t, with nearly 100 apps installed, only drops 3 - 6% overnight with 4g on.
My 1 week old galaxy s10e with airplane mode on drops 10% overnight.

I havent said anything about the draing % being too high or not. I said that it is not true that the phone does nothing while being in standby. Which is a fact.

Mine is draining around 12-15% overnight.
Very disappointed with the battery life of s10e
Any tweaks we can do?

I use Bixby Routines to automatically turn airplane mode on during the time I'm asleep and it went from draining 15% to only 5%.

I just updated to the latest update ASCA, battery drain issue seems to be fixed. It drops less than 1% per hour now. (5% over 6 hours)

ASCA? Is your phone with Verizon? How did you update? This battery drain is killing me too. The only positive is that it seems the battery drain is about the same while using the phone.

Mine is the international dual sim Exynos version. I just got an OTA update about 3 days ago. I was also having pretty bad standby battery drain. 15% in 8 hours. Last night it only dropped 4% in 8 hours, which is pretty amazing.

Thanks for the reply. I'm downloading it now. Hope it fixes mine. I know there are always bug when first launched. If things aren't straightened out within 6 months I'm going back to pixel once the 4 comes out.

I don't believe it helped. Still losing a good but while in standby with aod off

When it lost 4% in 8 hours, did you have AOD/wifi/data/bluetooth on?

AOD: OFF
Wifi: OFF
Data: ON all the time
Bluetooth: sometimes on sometimes off, I don't notice significant drain when it's on.
I literally had significant better battery life from one day to the next without doing anything. However I have had most of the useless apps disabled since day one, (Facebook, Bixby, Samsung stuff, etc.) I also have wifi and bluetooth scanning off. It is ON by default
Edit:
You should also follow some of these settings

New firmware ASD5 is out, maybe this will fix some draining.

I found deep sleep solution.
My s10e exynos (april firmware) was able to sleep only 10% of time.
After fix it can sleep 95+% (CPU Spy)
8 hours = 5% battery.
Open file “system/build.prop”
write “wifi.supplicant_scan_interval=200”

I dont see any standby drain. When I keep data on (locaion,wifi and bluetooth off) in the night it drained only 2-3 % battery. with data off/location/wifi/bluetooth off it was 100% in the morning.
But I have a different issue, When I am using the phone, I see a drain now which was not there initially. Android system is draining most of the power. I usually used to get 9+ hrs SOT with 2 days usage. but now Both have dropped below to 1&1/2 day and around 8 hours SOT.. Tried all the things found on net, but it didnt helped.

Same things happens with after update. Before the update it works for 2 days but now a it runs for 1 & half day max.

I did the update too, so you think it caused by update? Is samsung deliberately doing it as everyone suspects of them doing that they slow down the devices or its just a bug they didn't realize?

Maybe it's a bug.
All tests are under airplane mode, no cell signal.
WIFI ON with "battery saver" OFF takes 0.5% per hour drain.
WIFI OFF with "battery saver" ON takes <0.1% per hour drain.
BUT !!!
WIFI ON and "battery saver" ON at the same time, the standby drain will up to 1.3~2% per hour.
I have test this for more than 10 times, trying to avoid any other cause.
Finally I'm sure that "battery saver" mode will cost more standby drain if WIFI is ON. （ yeah, that sounds ridiculous
But I don't know why.

The battery performs well when in use (discharges at the rate of 10% per hour Heavy Gaming 'CoD: mobile', which is quite good I guess) but when the phone is idle, the battery drains quite fast about 2% per hour and the battery discharges about 10-15% over the night.
Losing 10-15% battery is not normal for a phone at all, also 10% of a 6000mAh battery is quite huge.
This problem persists. Any help is welcome!
EDIT :
I have uploaded the battery usage stats screenshots on google drive, check the link. I turn off WiFi and clear recent apps before going to bed but still, the battery drains heavily 15% over 6-7 hours.
CAN'T share the link because xda won't allow posting URLs here as I'm new to XDA forum
