Truly Outstanding Battery Performance review - Xperia Z3 Compact General

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 Lifetime

How does the battery behaves when compared with HTC HD and the original Diamond?
I found a good review article of the diamond2
"In terms of battery life the Diamond2 promises nearly double the amount of standby time over its predecessor. From my time using the Diamond2, starting with a full charge and with frequent use (web browsing/ music/ camera/ the excellent bubble burst game!), the next time the phone needed charging was five days later and even then this was more of a top up rather than the battery running on empty."
(http://www.mobiles.co.uk/htc-touch-diamond2-review.html)
i cant quite beleive a 5 day battery life on this phone! if it is true then it will be awesome but it has a smaller battery 1100 mah against 1350 in my phone currently which i get about 1.5 days out of it.
So i will be reserved, and slightly pessimistic

I would expect it to perform like your current phone (the HD, right?). smaller battery but smaller screen, so it should be about the same, and the htc provided data seems to be in line with that (about the same stand by, talk time and video talk time...)
So I think u are right to be pessimistic, but I also think that a higher capacity battery is possible with the same size as the 1100 mAh one: This TD2 battery is large, compared to the TD1 one: about 2 times as large, and TD1 was 900 mAh. Except if they are not of the same thickness, TD2 battery should have a higher capacity than just 1100 mAh...
I found nice shots comparing internals of TD1 and TD2, where we can see the 2 batteries
http://www.mobile01.com/newsdetail.php?id=7317
I do not know how TD2 battery compare size-wise to the HD, maybe you could post some pics of your battery? side by side shots of TD2, TD1 and HD batteries would be very nice, especial it we also have thickness shots anyone having acces to the 3 care to post those?
gkai, no i dont have an hd, i wish i had one. I only have a polaris which is why i cannot understand the 5 day battery life as if my current phone does not last that long. I think that something that is more powerful, bigger screen and a smaller battery will last as long, i just dont, and also mine is stated to have a 400 hr standby time and the td2 only has 360 hours.
So i will still be pessimistic and say that they had some wonderous phone to get it to last for 5 days! (or didnt touch it for about 3 days!)
also the physical size of the battery does not actually matter the rating of the battery is what matters and that is smaller therefore a smaller battery. The td1 i think was always said to have a really bad battery life so hopefully htc have heard this and made the td2 better with a longer battery life, we can all live in hope

hum, then it is possible: faster processor does not mean that it will drain battery faster: new generation are etched finer and use less power for same or more processing power. Screen can be (slightly) more efficient, and power saving of the different radio can be better too. But I expect the phone to be good for 1.5/2.5 days of typical usage, no more, given the current behavior of the HD, touch pro and touch diamond (which have almost exactly the same internal components)
So i will still be pessimistic and say that they had some wonderous phone to get it to last for 5 days! (or didnt touch it for about 3 days!)

The second is more likely, I doubt htc has changed the battery for the review (although it is possible). Good cell coverage is also good for battery life, if u have a cell tower nearby your phone will get better standby and communication time, same for wifi. I guess they both were in ideal condition and used the phone lightly...

hum, yes, it is the rating that count...but given that all good batteries use the same technology (lithium-polymer), mAh rating should be in direct relation with physical size: a large battery with small rating just means that your battery is of an older generation (unlikely), or that there is a lot of dead material (plastic packaging) in your battery. So either the TD2 battery is much thinner than TD1, or it is likely that higher capacity batteries with the same physical size will surface quite soon on the accessory market (I hope for the second case, battery life under normal usage is one of the most important factor for me, it is convenient to have more than 1 day of "heavy" use per charge, and less than one day under "normal" use means the phone is poor for me, whatever its other qualities...)
Bettery Life!
Hi Guys.. Wel 4 days in, and still on my first full charge!
According to the power screen, I have used
58 hours 25 minutes standby
Talktime 2 hours 22 minutes
device usage 3 hours 24 minutes
And stil have 4 bars left!
how to say i think that htc have finally sorted out battery problems and have made a phone with a good battery life. Seems like ive been told!

yes, my mistake However, my point stand: battery capacity should be directly linked to its physical size and weight, given that the technology and materials used are the same (especially if you compare the batteries of a single manufacturer, like HTC). If not, it mean that the battery is not optimal and that a higher capacity battery battery of the same size is likely to come afterwards (from htc or other suppliers). That's why I was interested in the physical size of the TD2 battery compared to other devices...Well, with some luck I will know today, maybe a batch will arrive this afternoon in my favorite mobile shop and I will pick one ;-)
After the first full charge and unplugging in the morning, mine lasted until the evening.
about the same as my D1.
I don't have bluetooth or wifi on ever.
So to be honest, with average use....it's still ****
Good job i bought myself a AA battery emergency charger for it as well
Extend batterylife
Maybe not what we're looking for , but it's a way to extend batterylife:
Just underclock your TD2 or other HTC-device:
Look here and here...
FYI: Overclocking is not possible (yet )!
@Juggles
Didn't expect to see you here, how's life? How's WmGurus?
So you have move to TD2.
How's it?
Good buy?
It's selling here from today in shops between SGD538 to SGD668. Maybe its a promo price.

Galaxy S6 Edge Battery Life

For those of you who have received your Galaxy S6 Edge already, congratulations I wish I was one of you ☺
Please report how your battery life (so far) is. I know it's a small sample but I'd like to know about.
Thanks
As far as i got to know, the battery life of Samsung Galaxy S6 is quite good and is having nice longevity. It offers the 2600 maH battery life which is much good from the other smartphone's that's in the market now days. http://cdn4.xda-developers.com/images/icons/icon14.gif
Got mine Saturday played a ton with it that day. Sunday was much of the same. The battery was so so. By no means will I ever rate a battery week one.
Today was more of a normal day and I was pleased with the battery life. It is difficult to say how it will be. I'm coming from a Note 4 so making comparisons isn't fair.
More to come...

This is the only reason why I might skip the edge. I currently have Z3 and it is just so much joy to never be worried about battery life. I don't even check what is the SOT anymore since I know that no matter what I do with the phone it will last the whole day.
However S6 edge just looks so gorgeous and my blocky Z3 starting to look so last season..

I agree with Andy. The Z3's battery life was the stuff of legends compared to the crap life of just about every other smartphone out there. I miss mine too sometimes but honestly, I'm rarely without power so a quick charge is a reasonable tradeoff.
Battery life, like mentioned is so so. It's better than my last phone, but definitely not up to z3 standard.

For playing games and youtube this is quite good! Let us see your stats later. Maybe at 50%, screen on time and usage details like above. You're the first to give real details. Thanks
Anybody else getting abnormal amount of "Cell Standby" drain? For reference, I am also on Wifi Calling. This cell standby battery usage is usually higher than screen on time.
My cell standby is 1% and I've been using the phone since 9am.
I have WiFi calling off and power save mode off. Tomorrow I will test it with power save mode on. Right now I'm sitting at 61 after 1hr of hulu. I did some textimg ,phone call and a few videos on ign also. . Next update will have pics and details
Same here. Cell standby is killing my battery. Factory reset may help?

Battery Life

Am I naive in expecting insane battery life? What am I missing here? Why isn't anyone really talking about how this should be crazy amounts? Most phones are closer to 3000mah.
I know the 810 is a hog, but it's an amoled display, not 4k, the oneplus two is only 3300, moto pure is only 3000, z5 2900, note 5 is 3000 as well. I have to believe with marshmellow (fingers crossed) and 3450 with an amoled display that's only 5.7" this is going to be insane, like 2 days on light use insane???
I'm hoping for some pretty good things from the battery life, i've got the Nexus 6 currently and it lasts me a day and a half with about 4 hours screen on time ( which is fine for me in all honesty )
This has a smaller display and a bigger battery, lets not forget that " sensor hub " that will help idle time immensely if it works as advertised
+Doze
+App standby
I've got a good feeling its gonna be a goodun
and this is the main reason why im picking the 6p over 5x because i strongly believe this has to be a two day battery life, everything is lining up so very good.
I'm expecting great stand by time, but once that screen is on, battery is going to drop like a rock. This was the case with the Moto X Pure at least. I was afraid to turn on that screen, my battery stats show a straight line going down.

It has a 2.5k display like most other flagships, and AMOLED is the display technology, it has nothing to do with the resolution.
Running dev Preview 3 I've gotten much better standby and battery life as a whole. While I don't expect much better life out of the box than I already have once it's tweaked with the right kernels etc it better be way better than my current gen especially to give up wireless charging....

The battery is gonna be INSANE! Huge reason why I went to the 6p ! The 6 on avg for me had 5 hours SOT so I can only imagine what this will be. I have the m9 right now and I cannot wait to ditch this thing. Battery is horrid on it
This the #1 reason I am getting this phone. The Note 5 has TERRIBLE battery for me as I'm a power user.
My S6E reminds me of my Evo 4G with WiMAX turned on. It's got to be better than the old school need to plug in everywhere feeling I have lately.

My pure has pretty bad battery life if the gpu gets used at all. Out of all the devices with the 808 in the same category the pure has by far the worst battery life for whatever reason.
The nexus p hopefully won't have as much of an issue.
Beware of radio signals... That leaks a lot too.
I like gsm endurance test as a review...moto x got 63 hours. Note 5 is a beast... So your if getting poor life on that... It's an app of signal issue. Try running off LTE and test.
I figure a good comparison is moto xpe. Stock almost, same size,qhd.
So factor in battery is 15% larger, Amoled should save 15 % (see note 5 Amoled vs moto x pure LCD) and marshmallow should save 15%. All that is being conservative. Let's say -5% for snapdragon 810 vs 808. So total 40% better than moto xpe. Which gets on average 3.5 to 4.5 sot time (ignoring the under 3 and over 6 which is usually tweaking or terrible signals)
So this should average at minimum 40% better. So at least 5 hours sot.....and max of 7?
Sounds reasonable. All of this was guessing while I await the phone

I average 7-8h of SOT with my Z3, hope the 6p can beat that. That's my only complain compare to the Z3

wow that really is amazing.
I'd be happy with that.
So far from all the phones I've had, The OPO on KitKat had the best battery life.
I had wifi, bt and gps on all day and I'd have around 20-50% left before I went to bed.
Lollipop destroyed that :crying:

Light use endurance

Once in a while, when your significant other yells at you, you might use your phone a bit less. Rate this thread to express how the Sony Xperia XZ2 Compact's battery performs under light use. A higher rating indicates that the device goes a long time when you're using the phone sparingly: no gaming or video/audio streaming, light web browsing, some calling and texts, etc.
Then, drop a comment if you have anything to add!
Coming from a Z3 compact, I can't help but feel this is a huge step back in terms of battery performance. I am really, really disappointed.
Woke up today at 7:00 with a full charge, watched about 40 minutes of YouTube which took me down to 68%; now it's 3:30 PM, the phone has barely seen any use and the battery is at 52%. On the Z3c when the battery was brand new, with this kind of use I would still be around 80%.
I really don't know what to say This is now a one-day-lasting phone like any other.

That's disappointing. I've got a Z3C that I use very lightly, mostly just 10 minutes of web browsing, 20 mins on WhatsApp and a bit more general screen on time. Maybe 45 to 60 mins total per day. I still get 3 days of battery life from my 3 and a half year old phone.
I'm considering either a XZ2C or Google Pixel (2016), but not really sold on either of them, both for being larger and the battery life being poorer
xz2c upgraded to 5" full hd screen, that's why battery life isn't as good as z3c. you can't have everything unfortunately.
still, I'm very happy with battery life of this phone, i get easily through 2 full days with one charge, and 6 hours sot, average usage.
it depends from your usage pattern of course, btw with same usage i used to get half the battery life with my previous S7.
not to mention size of this phone is perfect for me! very happy
ps. pixel 2016 is bigger than xz2c and battery lasts shorter.. and it is 2 years old phone.. wouldn't suggest it

Yeah, I know the Pixel is bigger and older, but I'm not too concerned with the performance difference and the both have 4GB of RAM, which is more important for me. also wonder if my light usage could stretch the Pixel out to 2 days too.
For the Z3C, community support for ROMs was OK, but I expect the Pixel will have a larger community and will continue to get updates for a longer time.
I think the sensible thing is for me to stick with the Z3C until it breaks, but we don't always make the sensible choice...
light use endurance is pretty good of this phone. if you just bought the phone, don't forget that the battery might need some time to adjust itself. and in my case it needed to drain the battery with some unknown usage after a system update.
My light use endurance is great. After 1 & 1/2 days being off the charger & 1 hr of SOT, I still had 70% left. Blows my Unlocked Galaxy S9+ (965U1) away in terms of both standby & in-use battery performance.
To be fair on the GS9+, however, that phone is connected to a Gear S3 Classic 24/7.

loving it, it's one week of use and i end everyday with battery at 50-60%
i use it for browsing, instant messagging, share and take photoes, waste time on 9gag and various networking configurations.
if you have battery drains check for installed applications. Disable facebook!
I still have over a day left, aiming for 3 days at the moment.

4,5 hours screen on here... so 1 day of stress use

Ya... it's a pity that the market apparently wants Full HD also on small screens. To me, dpi>300 doesn't make sense apart from VR (which I never use), but the market wants 430dpi+ apparently. Yes, there is a tiny difference between my Mi5S (428dpi) and my previous Moto G 2014 (294dpi) in terms of sharpnes - but I'd always take the longer battery life instead.

Hi,
I recently bought this phone and it's awesome but I noticed that when I unplug the phone from the charger, it drains quickly battery even in stand by. Right now it has 18 min SOT and it's 89% (most whatsapp). Not quite like yours. Since I did just 2-3 cycles, do I need to calibrate it? If so, how should I do it exactly?
Thanks a lot!

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 ASUS ZenFone 6 (2019) before depleting the battery.
Then, drop a comment if you have anything to add!
I'm waiting for users feedbacks about its SOT. I think that it will beat some records...
I'm expecting this phone to thrive in this category. The screen isn't some crazy 4K resolution and combine that with the 5000 mAh battery and we should have great SOT.
I have a bad itch to get a new phone and am tempted to get the OnePlus 7 Pro but I hear the 90hz refresh rate and fancy new screen are killing SOT
Whoever is going to post SOT, do not forget to mention screen resolution used, "tweaks" and "measures" taken in settings etc. Also show full screenshots. Thanks.
7 nm SoC coupled with a mostrous battery, it is expected to deliver great, great battyerylife.
As long as its well optimized. Other phones with big batteries have been awful due to power wastage.

There is a good review on youtube user name "Geekyranjit" He talks about the cons but says SOT is average gettting 4.5-6, he felt dropping the panel down to 60hz did not boost it enough. His biggest con he felt is that it is just really big, not balanced real well and it is heavy at over 200g. The Asus is a little smaller at 6.4 vs 6.67. I am just dying to order a new phone and replace the G7 ThinQ I am using that I got dirt cheap because of a cracked back glass corner but I have it in a Spigen so who cares.
I feel I should wait to see the Asus release and price in US as it may be what i go for. My concern is Asus updates but it will have an active ROM community I imagine

I saw an other reviewer on youtube with 75% battery remaining and around 3 hours of screen-on-time.
I come from an LG G6, our phones are great (it's the phone I've kept for longer, at 1.5 years), but the battery, AY the battery... Can't wait to see the results of the ultraWide camera pics... If they look just as decent as LG's, if not better, I'll get it too...

I found the LG G6 was just horrible overall and its battery life was garbage. I now have a G7 ThinQ and I have to say I will not buy another LG phone again. Prior to the G7 I tried HTC U11, P10 Plus and Essential PH1, that is the phone I regret selling , it was excellent , even the camera w the google cam port was decent but the overall aspects of the phone were very good
I wish Asus would release in US sooner

Chigztech on YouTube posted 9hrs 12mins sot with 6% remaining. I don't know if it was wifi or mobile but the Nex S exceeds those numbers with 1,000mah less. My best so far, mostly on wifi, has been 9hrs 4mins with 14% remaining and a new update a few days ago looks like it can approach 11 hours sot.
Battery life is very good according to gsmarena review.
https://m.gsmarena.com/asus_zenfone_6-review-1937.php
Wow not a lot of good to be said for the display.
This is a bit of a let down and is now making me re-consider this as a purchase, I watch a lot of YouTube so a decent display is kinda required.
Ah well...
SOT is about 11h which is insane for me. my phone now averaging 4.30 hours - 5 hours.
Asus says the screen is IPS with 600 nits and 100% DCI-P3 which should be plenty bright and color corrected. GSMarena for sure loves AMOLED but for my usage it looks like good enough.
Not sure if this has already been posted.

That Pixel 3a time was a surprise. Goes to show those who don't need a top-end chipset may be better saving the cash and enjoying the efficiency of mid-tier chips like the SD 6xx. Zenfone 6 does look fantastic for battery time, but not getting quite the 20% extra time from the 20% bigger battery, even against the 90hz OnePlus 7 Pro. Hope some software adjustments can be made to further improve it, because it's great, but not as good as expected when compared to others.

It lasts 30% longer than the 7 pro. And 20% more than the regular 7. Seems pretty good to me for an lcd display against oleds in a test that includes a bunch of video playback.

Indeed. GSMarena confirmed that in the browsing test and or in the talktime test, the ZenFone outlasted the others by a huge margin.
But how did you get 30% more? It was almost exactly 20% more than the 7 pro.
As a quick info: during setup of the phone, I lost around 25% over 10 hours with around 4 hours SOT. let's see how this settles during normal usage.
Edit: after day 1 and my regular usage pattern, I lost about 20%. This is about on par with the Lenovo P2. I will still have to see if a longer screen usage drains more (I suspect this due to the LCD instead of the AMOLED). Will report this later...
