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!

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.

How does the battery drain on your S6?

On my G3, when I fully charge the phone, it would stay at 100% for a VERY long time before dropping down to 99%. The most I've gotten out of the 1% before was about 25 minutes of SoT.
On my S6, once the phone is fully charged, it seems to drop to 99% very quickly, within just a couple minutes of using the device.
What causes this difference between the two models and does your S6 act the same way as mine?

So far my GF and I notice the battery drops quickly also.

That's pretty damn good if it do so. That's 10 hour SOT.
I can barely get 4 hours SOT.

Battery life is good for me.
19hrs since last charge, 52% power remaining. Screen on time of 1h 15min.

Yes but look at the great standby time.
Genetic is inline to get around 2-3hrs SOT with almost 40hrs Standby thats not too bad actually

But on screen time ia surely more important

Sure SOT is important but it depends on your standby too. Example 6hrs SOT with 8hrs Standby is kinda expected and normal. If you can get 6hrs SOT with 24hrs Standby the that is mightly impressive.

True but 19 hrs standby and 1 30 on screen is awful. That means you picked up the phone and drained it half way in an hour and a bit

Im not sure you get how it works bud.
That 1.5hrs SOT was not achieved in one continous sitting.
If you read my previous post i explained that you can get 6hrs SOT with the S6 easy but your standby will be short say around 8hrs. If you watch videos no stop on the S6 you could probably get 7-8hrs SOT before the battery is flat. This is normal for the S6.
Basically: Long SOT = shorter standby
Long standby = shorter SOT
The Holy Grail is Long Standby + Long SOT
EDIT: Im only referring to the S6 in my asaumption. There are flagships out that can get long standby and long SOT already out there namely Note4 and Mate7.

I have pretty terrible standby time though. An all nighter drained 10% but if i use the phone continuously i could get 4hrs of sot lol
Brightness was on auto

I get about a day standby with between 4-5 SOT.
Overnight drain is around 3-4%, I normally sleep around 7hrs a night.
I'm using XtreStoLite seriously debloated ROM, Ktoonsez 920F Kernel.
Also using App Ops and Disable Service to kill Google Play Services wakelocks.
Hope this helps you get better battery life bud.

Playing music through streaming music app Simfy, doesn't require the screen to stay on.
SOT isn't the only way to gauge a battery's performance.

Haha you guys took this thread pretty off-topic. My question was more related to the actual way your battery drains vs battery life.

Apologies OP didn't mean to derail tour thread.

Hmm i wouldnt want to root and unlock yet. Im gonna give it at least a month or two because the rattling home button is quite a concern to me. Even though its not really that bad

Man I must be lucky cause battery life for me looks REALLY good, especially considering the small capacity and the 2k display. Last night I fell asleep in front of the TV with my phone at 20%, woke up this morning and it was still at 20%. It's sipping battery nicely. I'm happy!

I noticed the same thing with my S6 the first night I got it. It came with 50% battery and after an update and me playing around with it a bit I went off to bed at about 23%. The next morning I woke up and it was at 22%. I consider that to be exceptional considering nothing was disabled and it wasn't even on its first charge.
Unfortunately I haven't been able to fully set up my S6 due to exams so it's been sitting on my desk looking pretty. I'm still using my S5 for the time being and plan to fully switch over to the S6 in the next few days!

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 Honor 9'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!

standby drain is minimal, just 2-3% at night

Getting 10 to 15% idle drain over night, any else facing the same issue? running european 130B

Rommco05 said:
No worries, yes. I think this update isn't much optimized for battery. We must wait for next updates I try do everything for better battery but nothing much help. B100 was better and Honor 8 on B389 was better too. Nevermind, Android O is behind door

Oh wow thanks for that info. Today I received B130 update and was going to install it now but if this is true I am not going to take the update and wait for the next one.

My battery drain after 6 days of ownership: never more than 5% over night (no flight mode enabled) for at least 7 hours inactivity. In the pic you can see no wake while being in sleep mode.
SoT ~5 hours.

Very minimal at 2%.

~10% overnight - B150

After 4 1/2 hours of no activity using power saving mode

This I can't understand. Almost 20% awake because of wlan related stuff. Should I factory reset?

Check your app consumption level list. something is probably using WiFi connection or perhaps you enabled the WiFi scanning feature

It looks pretty fine to me. On the other hand Android OS is using a lot of CPU. Mo WiFi scanning is disabled.
Thanks!

Also

Not massive drain overnight..
Only 2 to 4% which is normal..

Strange standby battery draining

So as you can see in the top of the screen shot my htc u11 went from 80% to 67% in 8 hours even though it was on standby with Wi-Fi turned off and on airplane mode and with also powersaving mode and hibernation manager.. I mean like what the hell.. Someonen tell me how this is possible. This is rhe worst standby i ever had on any phone

Btw my u11 is running the latest update

That's not battery usage...I know you're a newbie here, but you should know the basic battery information comes from phone settings.

Have u updated to 1.27? It fixes the standby drain. Used to have 60-70% drain overnight to 30+%

If you really want to determine which app drains your battery, a full charge is recommended.
Otherwise use Gsam and use adb to enable advanced mode, add a rule for "since now".

Wow 30% overnight? That doesn't sound right either...I probably lose 0.5%/hour on 1.13...my phone doesn't go into airplane mode over night either, I just turn off WiFi anr 4g...
Adi - given your countless threads of issues you've had so far, why haven't you returned the phone or gone to a help centre or something...it seems you have one problem after another...

I meant 30% of total stanby drain. Not 30% loss

If you're really serious about putting an HTC phone aside and bot touching it for several hours you should use the extreme power saving mode. It will still alert for calls. I come back after 12 hours to just a few percentage less.

That's why I sold my HTC U11, lost 5% an hour on cell standby, very poor battery life on this phone, the dongle stopped working and cracked the curved edge glass. Good camera though, and Iike HTC Sense. Bought a Moto Z Play, amazing battery life, easily 2 day battery life, has a headphone jack and a great Amoled display. Love this phone and nearly stock android.

High battery drain from Ambient Display

Is it just me or does the Ambient Display on this device have a pretty high battery drain?
AccuBattery reports 14% in 9 hours screen off drain with 91% of the time being deep sleep.
I'm coming from an S8 where the AOD drain is barely noticeable.
Is this normal or am I missing something?

Sent from my Pixel 3a using Tapatalk

If you turn the phone face down (or otherwise block the proximity sensor) the screen completely turns off. So it is pretty easy to control when the always on screen is on or off. I turn my phone face down overnight and usually see a 2% reduction in battery over 7-8 hours.
I think with the always on screen on, I see a drop of between 1-1.5% per hour on average. But my phone is also having more notifications and other activity that time of day too which keeps it from deep sleep.
tl/dr - you can leave the "always on screen" setting on all the time. If you don't need the screen and want to save battery, simply turn your phone face down and the screen shuts down completely after about 10 seconds.

Thanks for the input, everyone, I now settled with leaving it on and turning it face down over night or whenever I don't need it.
It just seems that this phone has a significantly higher standby drain than my former S8 in general. Already checking for some wakelocks or other causes for drains with BBS, but maybe it's just normal and I'm being paranoid. It's not an abnormally high drain either, guess I'm just spoiled ^^'

You don't have to put your phone face down. You just need to disable the ambient display and wake it up temporarily by double-tapping on the screen of lifting the phone, whenever you want to check the time or notifications.

I turned off ambient display also and switched over to double tap the screen to see my notifications without pressing the power button or unlocking.
