Battery life MUCH worse than Z2

The Z3 is a nice device, I enjoy the screen, thinness and weight, but the latter two definitely come at the expense of battery life.
Of course the faster CPU also plays a part. I'm just getting 3 hours of on screen time with my usage out of it. On the Z2 I got 4 hours.
I don't even know what these people do who get an insane 10 hours of screen on time out of theirs. Probably different kind of use, but still...
Once again I need to look having an external battery with me.
Disappointed.

Post your battery stats page. Seems odd to me. I have 2.5 hours of on screen time with 10 hours on battery at 78% at the moment.

I noticed that too since I switch from Z2. Its difficult to see from the power management tool indicating how many screen time ect.. the battery life just don't seems to be better then z2, and results and very random.. sometimes better then z2, sometimes worst then z2. Perheps firmware upgrade will help..

I have rolled through 3 Z3s due to defects on my 4th, all had great battery life up to 8.5 hours SOT, lowest is about 5 hrs SOT, before calibration. Give it a few charging cycles, or do a full charge and full discharge then recharge and use. You should then be fine. If that does not work maybe you got some errant apps or lots of them continously syncing. Also go to backup and reset menu and disable data logging.

been averaging a day and a half with over 8 hrs SOT with mine. mix of wifi/lte

I don't know how you guys do it. I always get around 3 hours SOT, no matter what. I wish there was a way to check wakelocks without root.

I think it has something to do with the apps you use.
Facebook, facebook messenger, snapchat, swiftkey and Nova Launcher gave me from 4+ estimated days (in stamina mode) to 1 day and 1 hours.

If I don't play games, I get between 6 and 8 hours SOT at the moment.
Check that google play services aren't burning through battery.
Should never get 2 or 3 or even 4 hours SOT unless you're playing games.
I use screen brightness on about 80% as well.

I'll be posting my power usage screenshots soon.
Off to the top off my head, screen was about 50% of power (with automatic brightness, and the slider set on the 1st third), the most power hungry app took about 25%, with the rest taken up by various other processes and apps.
WiFi off.

Facebook used to be a battery killer, I don't use it, but check on that.

Z3 has an incredible battery life
there's something wrong in the op

For my baterry stay perfectly (often 20% for system 20% standby and 50% screen)

Even if it's Facebook that eats 25% of power that still wouldn't account for the overall bad battery life.

Nope mate, sorry - my battery life is out of this world. It's not the Z3, it's your device - get it tested, re-flashed or inspected if the problem persists.

Oh no I already removed, I do not have any battery issues, I was just giving a tip to OP.

Right, so here are my power usage screen shots.
I don't think these can be called ok in any kind of scenario.
I would like to add that with my Z2 I didn't ever get up to the 6 or 7 hours other people were getting out of it, but with my kind of use I got 4 to 4.5 hours, which is considerably more than I'm getting right now.
I supposed it's kinda obvious, with a faster CPU and a smaller battery. What else could have happened. It just annoys me that Sony tries to tell us that battery life is BETTER than on the Z2. It is not.

Well, reviews uphold/confirm Sony's claims so its probably not the phone itself per say. I get 7-8.5 Hrs SOT easily. Disable autosync when un-needed and location services as well. Then see.

Just as everyone suspected, it's malwarebook causing abysmal battery life. Remove it and watch your phone get tons more battery.
Considering that you're one of the very few, if not only, getting poor battery.....I have no idea what else it could be. The phone get's better battery because of using the 801 SOC instead of the 800, which sips battery like fine wine, leading to the increase in life over the z2.

Malware.... Yeah, whatevs.
Fact remains that with the same usage as before my Z3 performs worse than my Z2, so there.

Battery life thread

No real life review thread on this one yet, so let's get the ball rolling on this. Any Telstra customers with their device have anything to say on this?

I haven't felt the need to charge mine yet. Because I don't have one.

And no one still share his battery life...
Can you share with us guys? Like guys with Pixel XL did

So, i'm gonna give it a go.
I am really satisfied with the battery life after three days of being a daily driver.
After my day of work it has 31% left with google assistant/now, 70% WiFi 30% LTE, Bluetooth always on, auto adjust brightness 3.56 hours display time, most of the time i used chrome.
No pics because i don't know to add them via mobile browser.
For now: much better than my old nex5 and OnePlusX.
I like!

I just got mine today and fully charged it and then synced my n5x, rebooted and it was down to 90%. Highly intensive processing so I'll not judge by that. Did some more setup, charged again. Phone call for about 30 min, down to 95%. Not bad but not great. It's way too early for me to make a determination as some here have been running it for 3 days with better results.
I'll either update this post or make a new one depending on traffic. Overnight will tell me a lot. I've been getting about 0.5% - 0.8% / hour drain overnight on my 5x so let's see how this one does. One thing I will say is that the phone is beautiful, great size, great feel. great display and quick as a bug. If the battery holds up it's a definite keeper for sure. If any of you have an iPhone 6 or 6s, put them side by side and I dare you to tell them apart. lol.

There is another thread on this but my battery is abysmsl

Google Play services battery drain. No unusual apps, pretty much out of the box because its getting replaced already due to screen issues. Not sure why...

I have really high android OS usage, but still get great battery life. 4 hours SOT, 16 hours usage. Will be interesting to see what i can get when I find the cause of this Android OS drain

Phone calls kill me but otherwise not looking too bad.

The phone lasts me the entire day, but by the end of the day its pretty close to dying out.
So not as good as my S7 Edge, or even close, however it's good enough.
I charge my phone every night, anyways, so doesn't really bother me.

I was less than impressed to be honest. I'll know more when I actually spend a few days with it out and in use.

I must not use my phone all that much. So far, extremely better battery than my iPhone 5s. I guess it is a doubling in mAh but also a bigger screen. I am happy with it so far.
Definitely doesn't charge to 70% in 15 minutes though like they bragged about.

Well they said "7 hours of use" from 15 minutes of charging, whatever the hell that means lol.

Coming from a Galaxy S6 Edge I am very happy with my battery life. Currently I'm at 1 day 5 hrs with 2 hrs 5 min phone calls and 1 hr 47 min of screentime with about an hour of music in there....right now I have 28% left. I typically use my phone for browsing the web, chatting, work email and facebook so all in all I'm very pleased.

They never said that. They said 7 hours of use in 15 minutes.

I'm actually pretty happy with it so far. I have the regular Pixel and in my few full days of normal usage I'm getting through the day pretty easily. 8AM - 11PM or so leaves me with about 10% left on the phone, and usually approx 4.5 hours of screen on time. This is especially impressive to me since this is with GPS ON, Bluetooth ON, mostly on LTE with only "ok" reception in my office, auto-brightness set half way, everything syncing, connected to my gear fit 2. That's definitely better than I got on the 5x and way better than I was getting on my last phone - the galaxy s7. I was getting maybe at most 3.5 hours screen on time with the S7, and that was with GPS OFF, brightness set to around 30% or as low as I could set it and still see clearly, and even with a ROM that included battery optimizations (and yes it did seem to provide slightly more battery than stock).
So this is great thus far. If I were going out late or something after work then I would probably top it up, but otherwise this is the first time in awhile I haven't felt the compulsion to constantly plug in my phone when I get a chance for fear it will die on me. I also hope that this will only improve as development picks up and people release optimized ROMs/Kernels.

Can someone with good battery life compare this to what they get?
13 hours
at 64%
Android System 176mah
Android OS 156mah
Screen 1hr 15m (151mah)
Voice Calls 15m (88mah)

They did actually at their reveal, I watched
"which Google said can deliver up to 70 percent in after 15 minutes on a charger."
Source: http://www.digitaltrends.com/mobile/google-pixel-news/#/11

Overall I'm really satisfied with the battery. after a night and day of heavy use, games, browsing, installing apps I'm still at 20%. Hardly any power drained in standby.

Decent
Battery has been pretty good for me so far. Seems to be settling in with optimization after a few days. Dropped 0% overnight last night which is awesome.
GSAM Monitor is saying my average is 19 hrs on, 4.5 hours of screen on time usage, 1-2 hours of screen off usage like phone calls, music.

Terrible, terrible battery life

Hi,
I recently bought the Moto X Pure Edition. Overall I am very pleased with it however there is one thing that constantly bugs me. The battery life is absolutely terrible. I'd seen no mention of this before I bought the device but having bought it, I'm realizing how terrible it is. I only get around 2-2.5 hours of screen on time. This is even worse than the moto g 2014 I owned before which i could easily get 3 hours with. Are other people having similar experiences and are there any potential solutions?
Also, can you guys suggest some custom ROMs for me with great battery life and very stable? Thanks!

Try TruPureXMM, it has the best battery life among other roms, AFAIK. Well, that's because it is based on stock. Try it out for yourself.
Sent from my XT1572 using Tapatalk

Am on stock and battery life is terrible. Can hardly end with 3h max with a full charge. And am one of those that stops most of the moto actions, low brightness, no wi-fi all time etc but still its worst battery life I've seen on a mobile. I think it has to do with the big screen it has!

check out frankenkernel. I get 5Hrs of SoT

I have a brand-new XT 1572 (on stock) and would not call its battery life terrible. I'm getting 5 hours continuous SoT on WiFi (not sure people are using the term "SoT" consistently - if the phone is on for 24 hours, I'd expect to get less than 5 hours SoT; same when I'm on a 4G connection, particularly a bad one). Not great, but acceptable (and not unexpected in light of XT 157x reviews).
I have a shortcut to Settings - battery on my home screen which I check frequently (while I'm in the process of getting familiar with the phone), I have OS Monitor on my home screen, and I occasionally check "running services" under "Developer Options". I use Nova Launcher which makes it very easy to force-stop an app just by long-tapping it, hitting "App info" and then stopping it.
All of this has caused me to uninstall a few power-hogging apps which I probably did not need in the first place; I also find I need to occasionally force-stop apps such as Neutron.

In an average day, from 6am-10pm of mixed WiFi/LTE usage I get about 3 hours total screen on time, and the majority of the time I have good-excellect signal strength... If I have average to poor signal strength, 2-2.5 hours SOT is normal. On WiFi with continuous usage I get 4+ hours. This is normal.
Sorry, but the battery life of this phone, especially if used in bright light or outdoors, is just not good. The display is gorgeous, but it is an unbelievable battery hog.
I have tried many ROMs and all have worse batter then stock... TruPureXMM is debloated stock but the battery life isn't much different because it's the screen that takes 80-90% of the power, no rom can change that.

I don't disagree with you - I call it "acceptable", you call it "just not good". I'd stop (far) short of calling it "terrible, terrible" though - and let's face it, this is why the device sells at the price point it does - which, to me, right now, is (a) close to the limit of what I'm prepared to pay for a smartphone and (b) great value for money. I'd rather be close to a charger or battery pack (in fact, I ordered a slim battery pack when I ordered the phone) with this phone at all times than owning a different phone (in this price range) with better battery life but other challenges/compromises I need to take. This devices's predecessor (for me) was the LG G3 - same thing, except that this device actually works.

I completely agree with the above. Thats main reason I havent used a custom Rom yet and still waiting for Stock 7 realease (hopefully we see it within the next 2 months) before trying a custom rom yet.
But i wanted to ask a question about the screen taking all that ℅ in the battery drain:
I remember i read somewhere in another thread an option that changes the screen resolution to FHD 1080 instead of QHD. You think that really makes the screen battery drain lighter or it doesnt matter !?

My prior phones were an LG G2 and an LG G4 and I was thinking that my 6 month old 2015 MXPE had good battery life. I'm not sure I have ever had a phone that lasted all day. I need to stop buying sub par phones I guess. My Pixel XL (once it gets here) will hopefully fix that.
This is from stock 6.0 - May 2016 Patches - using it on Verizon network
From GSam Battery Monitor, since August 15, 2016:
Averages Per Complete Charge -
Battery Life: 1d 5.3h (8h 29m Active)
Screen On: 3h 56m (5h 11m Max)
I pretty much just charge my phone for 45 - 50 minutes a day at work and do not leave it on the charger any longer than it has to be.

Eh, to each there own... My previous phone was a Moto G 2015, it easily got 5 hours SOT in a day with battery to spare, so to me the battery life on the X is poor, but not terrible... I also carry mini power stick for charging on the go, and a QC adapter.

What about it? Kernels, roms, etc, can't do anything about how much power the display uses, it's like trying to make a 100w light bulb use 40 watts... they can only effect other things like SOC, syncing, etc.

I agree here. A 5.7" screen will require more power just to light up. As far as changing resolution, you are still powering a 5.7" display. You might notice some slight difference in battery (and maybe fps) when playing games, but it is really related to going a little easier on the chips.

I'm still on true pure, not even the most recent build, and I could always get a day and a half of battery use, or at least a full day with moderate use.

Hey folks, just wanted to chime in on this. I had the phone since it's release and got around 5 to 6 hours of SoT with WiFi, GPS enabled (but not while using maps lol) and brightness set to about 50%. Battery life has gotten worse with each update and now I am waiting for Android 7 and I will reset my phone after it's installed.
Btw I disable any build in app that I don't use and uninstall apps that use to much battery in the background.

Am on Telsa 03/02 Build. And the battery life is as good as Stock. 3hrs SOT on LTE with Data ON the whole time and 4hrs SOT on WiFi. All the while keeping GPS ON High Accuracy and Ambient display.
No Greenify or any other battery booster.
The performance is better than Stock and all the features working near perfectly. It's a good choice, you get to use Nougat without really compromising the battery much.
Here is the post: https://forum.xda-developers.com/mo...ms-validus-t3561477/post71196401#post71196401
Also I have recently changed the resolution to 1080p. It doesn't increase battery life much but definitely boosts the performance.

All I can say is, despite the battery life being poor, you have TurboPower charger which definitely saves the day. The phone charges from 10% to 100% within half n hour.

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 3 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!

I have been with google phones for the last 5 years.
With the pixel line, I have never been so happy with my battery, specially pixel 2 xl. Battery would last 1.5 to 2 days...
However, with the 3, at the end of the day I had 39%, on a day I did not use the phone except for 10 sms, quick stocks check, 2 emails, no phone calls, 15 minutes of music with bt headphones in the metro.
Last night, I put it in safe mode, charged it. Took away from the charger at 6am, checked emails. At 8am, I had 90%.
Removed from safe mode at 8. Checked some messages, spoke for 10 minutes over the phone, checked emails and stocks. It is now 9:20am and my battery is at 80%
Not good. I am really disappointed.
If you have yours, please let me know how you feel about it.
I did see one youtuber complaining about his battery, I am afraid mine is defective. If not, I want to go back to the pixel 2 xl.

The battery is supposed to be adaptive, so it learns your usage. Most have said it needs a few days/a week before you get the full optimised life for it

Pixel 3 XL Battery Size: 3450 mAh
Pixel 2 XL Battery Size: 3,520 mAh
The Pixel 3 XL Battery is smaller no way around it

I have the XL and I charged it on the first day and let it drain to 1%. It lasted 27 hours and 5 hours and 40 minutes of screen time. I'll take it.

Battery life has been overall excellent. I havent been watching it like a hawk but it lasts all day with heavy usage. A- overall

There is really a misunderstanding about Adaptive Battery mode. All it really does is make sure that poorly written apps can't drain battery in the background if you rarely use them. If you don't have any apps like that Adaptive Battery doesn't really do anything. In my case I have no apps like that so Adaptive Battery on my Pixel 2 XL has made no difference.

I'm curious what kind of use got you that kind of battery life.
If you were using mobile data, had the screen really bright, played games, used navigation, etc that's pretty good.
If you were on wifi most of the time, lower screen brightness and doing non battery intensive tasks that's pretty disappointing.

I would say half and half wifi and mobile data. Screen was at 75%. Lots of web surfing, Netflix and YouTube. 45 minutes of navigation. Light email, texts, calls and photos. No games

I agree with you on that, but...
4 hours and 30 minutes off the charger, 6 days of using the phone:
2 XL: 96%
3 XL: 73%
The percentage here is MUCH larger than the battery size...
I am so disappointed and waiting for my replacement phone. If this continues... welcome 2 XL again...

what %/h (percent per hour) screen on?
i have 11%/h and 2.1%/h for screen on and off, combined 2.9%/h. over night it went from 23 to 17 i think. i charged to 80% this morning and at 39% from 9A to 10P.

The top of the screenshot is the battery life I'm getting at that moment, and the bottom is the average. This is mainly on wifi, with screen about 75% bright, using a VPN(idk if that drains it but seems like it). Anyway, I'm really happy with the battry life of this phone.

This really isn't the case at all. The naughty list of apps is really only one function of the adaptive battery management. Do you really think Google would be bragging about a task killer?

What you said was that it only helps with poorly written apps. That is totally, completely wrong- and I don't believe you bothered to read the article- you would know that.
https://venturebeat.com/2018/08/28/how-android-pies-adaptive-battery-and-adaptive-brightness-work/
See the section labeled "Adaptive Battery: 5 percent reduction in overall CPU". There is a noticable difference with the battery management on the Pixel 2 &3. It takes 2-3 weeks from my experience & it DOES in fact learn and adjust to a users usage. That's why they are calling it AI. You can't just look at one of those battery apps and judge the phone over a 24 hour period, nothing quantitative there. Use the phone as you normally would for a period of time and then and ONLY then can you fairly judge it.
This ties into Google's position on the camera as well, "bigger/more" isn't ALWAYS better. Machine learning can do a lot, and you need look no further than the performance of the camera to see that.
That being said- could the battery be bigger? Sure. It's actually 100ma less than the 2XL this year. But why? If you can get the same performance with "less"- it would be pointless to spend more money on "bigger."

What you said was that it only helps with poorly written apps. That is totally, completely wrong- and I don't believe you bothered to read the article- you would know that.
https://venturebeat.com/2018/08/28/how-android-pies-adaptive-battery-and-adaptive-brightness-work/
See the section labeled "Adaptive Battery: 5 percent reduction in overall CPU". There is a noticable difference with the battery management on the Pixel 2 &3. It takes 2-3 weeks from my experience & it DOES in fact learn and adjust to a users usage. That's why they are calling it AI. You can't just look at one of those battery apps and judge the phone over a 24 hour period, nothing quantitative there. Use the phone as you normally would for a period of time and then and ONLY then can you fairly judge it.

Noticable battery improvement on the Pixel 2 XL? If you had poorly behaving apps then yes. I don't have any apps that hog battery in the background when they shouldn't. My battery life on my Pixel 2 XL running Pie is no different than it was on Oreo. I actually had a huge battery life decrease after I updated to Pie but a factory reset got me back to Oreo battery life.
And a 5% reduction of CPU means nothing. That's so tiny it isn't noticable. It's not the CPU or software that has the biggest impact on battery life. It's the screen and the size of the battery. Software optimizations help a little bit but not enough to even be worth mentioning.
The Pixel 3 XL doesn't get the same battery as the Pixel 2 XL. Not even close. I can do anything with my Pixel 2 XL other than GPS navigation and games and get 7-7.5 hours screen on time over 24 hours off the charger. That's down from 9 hours screen on time over 40 hours when it was new. The Pixel 3 XL isn't getting close to that. A combination of a bigger screen, higher resolution and smaller battery is the reason.

I don't know why people keep making a thing about the XL 3 battery being smaller than the XL 2 battery as though there has been some major downgrade, It is 2% smaller.
That isn't going to make any significant or noticeable difference. If you take a 6 hour SOT that would make 7 minutes difference! If there is a significant difference in the battery life of the XL 3 v XL 2 then it is nothing to do with the difference in battery size.
I too would have preferred a significantly bigger battery but most phone manufacturers continue to ignore this. I know some phones do have larger batteries, like any phone choice, you balance all the features offered and make your choice.

I'm getting 2.5% drain per hour regardless of whether the ambient display is on or not. It also doesn't change if I turn adaptive battery on or off.

I don't get it..

Yeah, this is one decision that Google made that I truly don't understand. Why would you downgrade the battery when you're adding more horsepower to the device?! I can maybe see doing this for the Pixel 3 but absolutely not for the Pixel 3 XL! My only complaint is the battery life, that being said, I know it's supposed to be adaptive, so it may improve over time. I'm hoping that proves to be the case!
UPDATE: I tend to agree with the point another person made that it's a 7% difference, though, I for sure would have preferred it was a 7% gain vs. a loss.

The problem all comes down to wireless charging: the wireless charging coil steals a couple mm of space....that's the only reason why the battery is smaller.
What I don't really get instead is why everyone is so freaking happy about wireless charging...I mean, for a marginal gain in charging behavior, we loose in battery capacity!

The pixel 3 xl drains much faster than the pixel 2 xl. It might be the new screen from Samsung consumes more energy but I'm not entirely sure.

S10 Plus Better battery life on wqhd

Hey guys, my s10 plus battery wasnt that great out the box I was averaging 4:30 sot that's with alot of spotify 1 hour of YouTube snapchat all day and all the social apps, I recently changed it to wqhd and not only my screen looks better my battery life is much better I'm now getting 5:30-6 hours of sot it seems like Samsung optimised the display for the battery where on my s9 plus wqhd was draining more battery but it seems to improve battery on s10, just seeing if anyone's had the same experience

Hmmm.. Let me try that. I've only used FHD on my S10 since I got it.

Plus I realised this is a expensive phone with a beautiful display and dont feel like you should be using it at fhd+

What I know is that you have to be patient. The internal AI will adopt to your usage and then improve your battery life. It will take 2 or 3 weeks.

2 or 3 weeks? where did you get this nonsense info? my S10+ (Exynos) had terrible for first 4 days when there was pattern usage learning going on..after that its all perfect...dont tell me that $1000 needs to be used 2 or 3 weeks to get to normal conditions

I have been told this by my friend who works in Samsung Store. I have the phone (S10 Exynos) for 11 days now and it is still not good as my S7 Edge...I have 79% now without much of usage. I took it from the charger at 7:40 or so.

Nope, that was just coincidence. Changing to WQHD+ will not improve battery life. It will reduce battery life by a very tiny amount. You must have had something else happen at the same time.
This is why comparing battry life with others is pointless, because there are just too many variables. As you have found, you can't even compare battery life with yourself without getting onconsistent results.

I changed it back to fhd+ for a day and my battery did seem worse, wqhd gives me much better battery life

No reason it should take weeks to settle in. My first full day on the s10+ was 5.5 hours screen on time and still had 49% left after 16 hours. Currently on 40 hours off charger 7.2hrs sot and 17% left. This battery really is amazing but will always vary between users. Can't see how wqhd could do anything but hurt battery life but I'll run it tomorrow just to see what happens.

Thats insane. 5.5hours sot with almost 50% battery left? Surely you have turned off LOTS of features / adjusted brightness and various settings?
For me to achieve that i would need to use the phone at almost its lowest brightness and disable background activity, turn off auto sync, bluetooth, and pretty much anything else thats a battery drain!

I don't think I have that much disabled. Brightness is on auto and is often pretty bright, power saver is on medium so background data is disabled along with auto sync because I don't need push notifications. I have bixby routines turn on auto sync when charging at night to sync anything that needs it. I use Bluetooth in the car and for headphones at the gym. Probably 6-7 Bluetooth hours on that screenshot. Not much WiFi since I'm never home. Location on. Don't use bixby itself because, well, who does? It's pretty effortless really. Especially compared to my note 8 where it's nearly dead at 5 hours sot.

I'm upped the resolution on my S10 plus from the beginning and getting anywhere from 8-9 hours sot. Way better than the iPhone 10s Max I had! A lot faster too!

With a week so far of using the S10 I've gotten equal battery life with FHD and QHD. About 4.5hrs SOT and 15-19 hours up time.

Ah you have battery saver mode on. It works magic to extend your battery life. It gave me good life on my S9+ when I had it. But my logic is why did I have to have battery saver on to match the battery life that I got on my 1+6 and Pixel 2 XL?

Yeah. I've always used battery saver on every phone I've had. I'm kind of a battery life junky and when battery drains fast or when idling it bothers me. Some reason I got better life in my note 8 without saver on though. Helps on my s10 though and easily outlasts my wife's pixel 2 XL. It really all just depends on the user though. 4.5 sot is still a respectable time in my opinion especially for heavier users and about what I got on my note 8 and had no complaints. Difference now though is that I can use the s10 HEAVILY in one day and it won't die whereas my note 8 would have been dead hours before and would need a boost late in the day.
