Truly Outstanding Battery Performance review

From PhoneArena, this really does showcase how both the Z3 & Z3 compact have incredible battery life. Which also reinforces other sites data as different places use different techniques to get battery score.
Motorola take note...

It's not on the chart because of retesting, but one of the comments said the Z3C had nearly 15 hours screen on time?!?! That's unbelievable!

i know the z3/z3c are the same specs. but is the same battery too? if so, i can see that being true.

No, battery is smaller, but apparently better.

Z3 is 3100 mAh, Z3C is 2600mAh. Also Z3 is 1080p with 3GB RAM and Z3C is 720p with 2GB. Both phones seem to have really great battery performance but the Z3C is truly outstanding. Not sure what's up.

I have a hard time believing they got 5 hours on screen time on one charge with a moto x. I barely get two, dont think I've ever had three.

I've had 6.5 hrs SOT on my moto G

Yeah, battery life is much better on the G than the X, because of no LTE and no always on listening. I use Voiceless Control every once in a while, not that often. I don't think the trade off for battery life is worth it overall. I'd gladly give it up and am looking forward to my new Z3C, especially if this 15 hours on screen time number is accurate.

So apparently the Z3C originally managed 14 hours and 44 minutes.
That being the case, I can definitely see why they're re-testing it, as there is clearly a serious flaw in their original test. I expect this phone to get great battery life, but not ~50% more battery life than the already excellent Z3, which has a larger battery. True, the Z3C has a smaller screen, but that's counterbalanced by a considerably smaller battery.
It would be hilarious if their test was accurate though. That would be really incredible battery life for such a compact, yet powerful, phone. Still, I'm not counting on it.

I don't see why it's so unbelievable. The Z3 has 125% more pixels than the Z3C, but only 19% more battery capacity. I would expect the Compact to have much better battery life.

Try 2.25x as many pixels.
1080P = 1920*1080 = 2,073,600
720P = 1280*720 = 921,600
2073600/921600 = 2.25
Huge difference in the number of pixels this phone is pushing. At 60% brightness or whatever their test is set to, I can totally see this phone smashing its big brother when it comes to battery life and SOT.

Saying 125% more is the same as saying 2.25 times. "125% more than x" is equal to x + 1.25x
That said, you and I are in agreement.

That's incredible battery life if true, I'd be interested to see other reports as well. I know GSMArena also scored it one of the highest on their test.

I tend to trust GSMArena for their thorough reviews, Phone Arena are not quite as good, but they're both singing from the same hymn sheet. I think its going to be good.

The GSM Arena review says you can do just under 15 hours internet browsing, or just over 15 hours video playback. If you're doing that, then that means screen on time. So this would seem to confirm the PA battery life results of just under 15 hours screen on time as well wouldn't it?

sh!t that sounds pretty logical to me. I don't know what I'm going to do with myself if this phone seriously gets 13-15 hours of SoT. That is just ridiculously unheard of. If these tests are accurate, the Z3C even beats that Huawei phone with a 4100 mAh battery :laugh: :good:

I'll still take 10 hours. And that's in regular mode, not using any of the battery saver modes.

10 hours is a much more realistic number. Sure, a smaller screen with a lower resolution is going to help, but it's not a magical solution that will lower overall energy usage by more than 50%.
Either way though, 10 hours endurance is great. The Z3 Compact is going to be one heck of a phone.

Battery life

The early reports are showing only 3.5-4 hours of SOT. If so, this is shameful on a 3450mah battery. Can anyone say they have seen better than this?
Sent from my Nexus 5X using Tapatalk

Look in the review thread. Some reviews say 6+ hours, some say less. Depends dramatically on cell signal strength, screen brightness, and application cpu use so review numbers are really only useful for comparison to other phones that were tested the exact same way.
Sent from my SM-N920V using Tapatalk

In Dave Lee's review, he got 5.5 hours of SoT during a span of 32 hours.

Battery life is extremely subjective, most reviewers will have vastly different usage requirements out of their devices.
There is also countless optimizations that can be done to further improve battery life, most reviewers don't know this and tend to not include it in their reviews and thus end up with lower than expected battery life.
I can kill a smartphone in 2 hours with extremely heavy use, recording 4k and playing games will easily do this while you can take the same device and get 5 hours of use browsing the web and reading forums.
It's all extremely subjective and unfortunately you can't accurately predict the battery life you will get simply because your usage, signal strength and many other factors vary from other users.

You are true for a few reports, however I saw almost all of them and most of them had between 4.5 to 6 hours SOT

Not that it will be necessary but is it possible to easily lower the screen resolution and would it substantially affect battery life?

You mean changing the dpi? I gues it's not hard. There's videos on youtube how to change your phone's dpi through adb without root... But I don't think it will have a difference in batterylife though...

Yes, sorry I did mean DPI. Having to power more pixels doesn't equate to more power?

I don't think changing the DPI has any effect on the number of pixels being used, since the entire screen is still being used. More likely it reduces load on the CPU/GPU by not having to render as high of a resolution.

But this is amoled and only the non-black pixels use power, not every pixel.

First full day on the phone 3:00am-3:57pm not touching a charger, currently at 3h 33m 28s of screen on time using 468mAh and 23% battery remaining (calculated to 4.5 hours SOT for a full 100%). This includes web browsing, facebook, inbox, navigation with screen off, audible book downloads on wifi with screen off, 1 hour of audible playing with screen off, playing 30 min of games, running 2 benchmarks, tweaking settings, 1.5 hours of screen off speaker phone, various xda posts. With the amount of work my phone has done I am perfectly happy with that run time.

Battery usage after first full charge, you can see doze working over night where it lost just 2%

How on earth are you people getting 6 hours sot? Don't get me wrong. That's what we should be getting in such a large battery but I'm trending at 4 hours and have perfect signal

Have a read of this thread,i have done tests over the last 4 days .Some using WiFi only,some using mobile data only( in poor signal area ) some using both .Best was 7 hrs + SOT over WiFi only ,6 hrs + over WiFi / mobile data, 4 hrs 48 mins( with 17% battery remaining) on mobile data only and that was mainly no 4G,just 3G and some times just 2G due to poor signal area

Immense battery drain with the screen on

The battery on this phone is generally good, but some things drain the battery more than I think they should. Standby drain is great (3-5% overnight) but the screen murders the battery. It drops 1% every 4-5 minutes of light tasks such as browsing social media and Chrome, but the drain gets much worse with anything that's more demanding on the processor. For example, 23 minutes of gaming on my PS1 emulator killed 10% of battery, and just 13 minutes of Crossy Road killed 6%.
Is there any way to improve battery life when the screen is on, or is this normal power consumption for a 2k display like this one? For reference, I have it set on auto brightness at the lowest setting to save battery already. Also, my phone gets 4-5 hrs SOT with moderate usage and maybe 30min-1hr of gaming. If it's the latter, I'd take a 1080p screen any day for better battery life...

Turn off auto brightness. Other than that, the screen is going to draw a fixed amount of power. Also, resolution has very little to do with how much power the screen uses, it's all panel size and brightness.

Pretty much the only knob you have is display brightness.

I thought resolution has everything to do with how much power the screen uses? The way I understood it a screen with a given resolution has the same amount of pixels whether it's 5.5" or 5.7" or some other size, hence phones with different size screens but the same resolution having different PPI's.

I turn it on only when I'm outside. Aside from affecting power draw due to brightness, does auto brightness also draw extra battery from having to operate the light sensor constantly as well?
Other than that, I've already been doing everything you guys have suggested. Do you all experience the same type of drain that I do?

The backlight is the primary power user in the screen. It doesn't care if there is 1 pixel or 5 million. The GPU will use more power at higher resolutions, but a 5.5" FHD screen will use nearly the same power as a 5.5" 4K screen.
Sent from my DROID Turbo 2

But OLED displays such as the one on the Turbo 2 don't have backlights, so the higher the resolution, the more pixels the battery has to light up and the more it drains the battery?

The pixels are smaller, and there is less power use per pixel than on a lower resolution display. Will it drain more power? Yes, but the amount is likely negligible.

What I would recommend
I know a little about a lot, When it comes to Android phones and phones in general,
The auto brightness feature always has an effect on battery life I always tell people it is much better to set this manually and to change it when it's needed. Also more modern phone os's allow this setting to be toggled quite easily. As to what screen panel uses more power I don't know a lot about that but I would have to agree with the idea that the higher the resolution the more power it draws. Good luck to you and hopefully we see marshmallow soon around the globe!

Okay. I've also noticed that the screen drains power a lot slower once battery level is below 30%. Has anyone else experienced this? Regardless, I'll calibrate my battery today and report back if it makes any difference or not.

You could also try Lux, it has a lot more options when it comes to auto adjusting the screen.

Newly bought S8 and a 4.5h battery life. Is is normal?

So I got my GS8 yesterday and this is the battery life I get with:
AOD off
No battery saving profile
Wifi on all the time
4G network but no data
Automatic brightness
No gaming, about an hour of video playback
Since I can't share outside links I'll just write the info here: (From 100% to 3%)
Last charged: 10h ago
Screen on time: 4 hours and 30 minutes (812mAh)
Android System: CPU total: 3 hours and 11 minutes (312mAh)
This is not even close to what I expected, do you think this is normal?

Normal. It's happened with both my S8 and my G6. Your battery life will get better in 3-5 days. Android is setting stuff up and optimizing battery life behind the scenes.

You bought it yesterday. Give it time to settle.
Also, turn off automatic Samsung cloud backup, it's on by default.

What did you expect from a 3000mah battery? It all depends how you use the phone, i can empty the battery in an hour if I want.
4.5h is more than respectable, if you want more lower the brightness and use a black theme.

It pretty much. Also depend on how many apps you installed. If you dont want it run much, add it to smart manager sleep list. My idle about 3hrs/1% man. This is my battery current round and apps list. About 10% wasted battery because I did clear davikcache a few times

This should be normal. with AOD on, my phone takes about 2% per hour, but when browsing webpages, every 1.5 hours costs about 10% of power, watching videos should take more. also, the 1080p and 2k resolution have notable differences. so it seems that the white-background screen cuts down most of battery life, i think.

hmm, i turned my phone as power-saving as possible - brightness is less than half of the bar, suspended all background apps, and FHD resolution. also, after some days of usage, the system should be able to auto balance the power consumption by sleeping some unused apps and some Samsung's system services maybe. so i don't think this is an issue.

Dont believe every sot someone posts here, i've seen a few 8 or 9 hour sot's but i'll bet the brightness was as dim as can be and they used a black theme. Or they were probably reading a book on the phone which uses no cpu at all or using the battery saving feature.
Your z1 also had a 3000mah battery, yet it had a smaller/dimmer screen, lower resolution, less ram, much slower cpu/gpu. How can you be complaining?

yeah, you're right, the AMOLED screen with high brightness and white color is the real battery killer. also BTW, does the 'sot' mean 'screen-on time'? sorry for my bad English...

Yup screen on time

4.5h is more than enough ! I am coming from a S6E+ it used to give me 2h SOT MAX ! Hated my life with it.

Do you plat Pokemon Go? I find a lot of people I see complaining about battery do, that game is very poorly optimized for battery consumption.

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Razer Phone before depleting the battery.
Then, drop a comment if you have anything to add!

1hr 30 mins of sot left with 64% battery
48mins of gaming

Battery saver on the whole time+720+60hz, on wifi+cell, web browsing+streaming, music, vids, txting, few games, 9+ hours SOT.
GF's phone, ton of gaming/txting/fb/web, battery saver only turned on after <10%, 7+ hours SOT.

SOT is good not great but that is at 120 1440. I easily make it through the day so why change it.

This phone has amazing SOT! I'm sitting here 13hrs in, 37% battery remaining with 6hrs screen on so far.. Lots of browsing, some Lineage 2, and an hour or two of music streaming so far.. That's with bt/wifi/lte, auto brightness, max resolution and refresh rate. Just using stock without any battery saving stuff.. Alot nicer then my 6p for sure!

Its amazing i was watching episodes on netflix after 5 hours screen on time 62% of battery left.

Hi! I have a 6P and I'm on the fence about this phone. I absolutely love that it has a higher refresh rate screen, massive battery and lots of RAM. I love my 6P but the battery life could be better and the Ram management is terrible( my biggest grip). The lackluster camera on the Razer doesn't reeeeaally bother me as I don't take many pictures but how does the max screen brightness compare between the phones? If they are relatively similar that's great because I'm happy with the brightness on my 6P. Thanks for your help.

It's more than enough.. Especially if you turn off auto-brightness it gets very bright! I run my phone dimmer cause I like it, but it gets very bright, not sure what all the criticism was about.
The camera is lacking features and the quality is still average at best, but if you use one of the google/pixel camera ports it helps with the quality.. I really don't find the quality that bad myself, but the missing features definitely compared to the opengapps one.

Best so far I've had.
Average around 6hrs. In my opinion best battery life I've ever had on a phone.
Resolution @ 1440p
Refresh @ 120hz

OMG, don't get me started on the s8.. lol

Resolution 1440p
Refresh 120Hz
Brightness ~35%
Ambient Display Off
Adaptive Brightness Off
Night light Off
Build number .853
SOT ~8hours (2hours of which was Maps in the car.)
~10min voice call
~2hour WhatsApp call
Quite unprecedented since my many years since day dot with Android.
As good as the SOT is, I'm more appreciating how the device deep sleeps - I like that flat line on the graph.
No need to fight with Android ecosystem or any quirky issues preventing deep sleep: the Razer sleeps like a baby (no greenify, battery improvement nor brevent nor lspeed nor sdmaid equivalent apps) :good:
Well done Razer.
Now sort the tiny quirks and smack this out of the park

Nice!!
I am still impressed with the battery management.

Almost 6 hours (last time I checked). So very impressive.

Easily over 4 hours with heavy gaming and app downloading. ... and music playing over Bluetooth all day.

4 hours to 4.30 hours with 1+ gaming (guns of boom) medium settings (1440p 90Hz). good standby drain

Anyone mind posting battery degraded sot results after owning it for a while? Ty
