Battery life with SD821 and +400mAh

[ForcedZucchini]

Having read a few reviews, it looks like we can expect some good battery life and SOT with the 3T compared to the 3.

I was expecting a slight increment on endurance and wasn't quite prepared for the 3T's epic stamina. It lasted 16 hours and seven minutes on Engadget's battery test, which involves looping an HD video with the screen set to 50 percent brightness until the device conks out. That's almost six hours more than the OnePlus 3's runtime, and two hours longer than the Google Pixel XL, which has a 3,450mAh bank.

That is why a 1080p doesn't bother me at all. I'll take that extra performance and battery life at the expense of a worse VR experience.

I always wonder how they make these tests, when i play a video on lowest brightness with no apps installed it doesn't lasts longer than 7 hours lol

Is this better than OnePlus 3?

OP2 owner here, I jumped to a Moto G4 Play for size and battery reasons, its working quite well once I bought a better quality 64GB SD card.

The OP3 wasnt enough of a benefit to me to upgrade, but the battery life of the OP3T looks interesting. Looking for more real world battery tests.

Given the SD821 is so similar to the SD820 and 3400mah is only 13% more than the 3000mah, sure most of this much better battery life is software changes?

From what I understand, there is a few key different from SD820 to SD821. and not just speed but power/thermal efficiency as well. Many people look at benchmark to see how well the CPU/GPU are under the same condition. But that's not a full story. Sure Benchmark do stress the CPU and GPU, but imagine you are running a game. Even if the game is not as stressful as a benchmark software, but benchmarking only run for a few minutes but you maybe running game for half an hour to an hour. What happened then? For the SD820, many of the power get transfer into heat, while on SD821 because it's more efficient and also in the case of OP3T, it has slightly larger battery capacity, this lead to the phone running cooler and last longer. You can see on Engadget that it can run loop of video six hours longer than OP3 even though it only has 13% more battery capacity. I would also speculate that this means playing game over a period of time, it would be less jumpy compared to OP3 as well.

So are you claiming that as real-world load doesn't stress the hardware to its maximum, if you make the hardware faster it runs slower so more efficient?

The benchmarks coming out seem unbelievably better. Wondering why and also looking for more benchmarks.

Not exactly, Benchmark only tell what the CPU/GPU is capable off at peak, but it's not a real world scenario. What matter to us is what would the phone do in the real world. Even what Engadget did for doing a video marathon test is not a real world scenario, but I wouldn't be surprise if a parent lent their child a phone to watch YouTube/cartoon for half a day on a long commute . Combining all these test result would point us to the right direction as to what would happened in the situation that suit us best.

In my opinion, if you are not stressing your phone all the time, in term of battery life it probably not matter between OP3 and OP3T. Seriously, at the end of the day you would have like half the battery left, most of you can plug it in the car or at home. If all you do is web surfing all day, then battery different will not be much, as most of the power will be consumed largely by screen and wifi/cell. But for some something that do stress the phone quite a bit to a lot, like watching video and playing games for a period of time, then the difference in battery life would be more significant, and that would be due to both the difference in battery and SoC (not just battery alone).

In my first two battery cycles with OP3T (from 100% to 8% (1st run) / 11% (2nd run) I got 6-6,5 hours of SOT. Love it. The only thing that could be better is the speed in which the home button reacts when tapping home button to get out of an application to home screen (before I had iphone 7 from which I upgraded to OP3T (definitely an upgrade ..android in general is just way more enjoyable!!!), I had xiaomi mi5 which had way more responsive capacitive home button in regard of how fast it reacts..here its a little bit slow, but I am probably just too picky).

Mostly these apps throughout the whole day for random period of time:
1. Whatsapp;
2. Chrome;
3. Youtube;
4. Gmail;
5. Spotify (streaming to car audio system through BT for ~1 hour in each cycle)

Throughout those 2 cycles I was constantly on moble data (4G) (never on WIFI), Sync: ON, location - OFF, Bluetooth - on (no wifi). Very impressed with OxygenOS 3.5.1. and OP3T so far.

My last 4 phones -> nexus 5x, galaxy s6, xiaomi mi5, iphone 7..

Do you have anything setup for home button double press shortcut? In general, setting a short cut for home button double press slows down home button response....

Thanks man. You were right. I changed double tap action to none and it's as responsive as it needs be. :good: It actually makes so much sense - in order to enable double tap function on the same button which was a set action on single tap you have include a time gap in order to allow the 2nd tap to occur! Considering that there are still 2 more capacitive buttons which include double tap/long press actions I don't see it as a major flaw.

Yes, software has to wait to see if it is single tap or double tap..but if you disable it, it always going to perform single tap action without waiting

Right, that makes sense.

Btw, (1) do you know if its possible to remove vibration when double tapping to wake the device and (2) what app if any do you use to edit led notifications ? Whatsapp and textra allows you to chose the color of led notificaton, but for instance, Gmail app, Default Dialer app does not have the option to change color of led notification.

Light flow is probably going to be the best app to change the color of the led.

How do you know it runs cooler?
According to technobuffalo it gets more warm than the 3

According to XDA article here,

[FONT=&quot]as we’ve run our 3DMark and GFXBench endurance tests under controlled conditions on both devices at the same time and found that, overall, temperature remained nearly identical with a fluctuating difference of about ±0.5°C, and overall throttling was also similar and below 5% on both devices. [/FONT][FONT=&quot]The OnePlus 3T did ultimately sustain a higher score in these tests, as expected, meaning that the extra bump in graphics performance doesn’t vanish the moment you stress the processor. In fact, they typically throttle at about the same point, and even when throttled the OnePlus 3T performs better than the OnePlus 3 at its peak. [/FONT]

On previous posts is mentioned that setting the home button to launch a shortcut or to open an app make it laggy......is this correct?....
I'm planning to order op3t but this makes me worrying a little bit.....

 

[93drago]

Setting an action for double tap will make it a little less responsive because after first tap it will have a short time gate in which it will wait for that possible second tap.

It is with every phone...if you setup some short cut for home button double press, home button response will be little delayed...

3rd cycle (from 11-100%) was pretty much the same. 6hours of sot easy maybe even more. Today no car audio (spotify through bt).
