What's the battery life like?

Spec-wise, this phone seems great, with the glaring exception of the battery's size.

I'm hoping someone with the phone could let me know, ideally as detailed as possible, what the battery life is like. Thanks!

Initial tests mentioned a screen on time of 4h+, which is nothing to write home about.
On another hand, even though we have a "mere" 3k mAh battery & 5.7" screen, the latter is amoled, which should offer considerable savings as compared to LCD.
I'm waiting for my unit to be shipped, will do some tests & share.

This is why it is somewhat tempting to go with the $399 5.5" model and the Snapdragon 625. You lose a bit from the 5.7" SD 820: no AMOLED, smaller sensor in the camera, only 4 GB of RAM, but based on battery tests with other phones with the 625, the life could be better than the 820 model.

Review units in the U.S. are starting to appear, TechnoBuffalo recently received their 5.7" and did a quick preview on it.

FYI. PCMagazine has a review up of the 5.7", SD 820 version. They managed about 7 1/4 hours on their video run-down test. The Axon 7 with the same test ran about 6 hours, Samsung S7 Edge, around 10(!).

They panned the phone though. TechnoBuffalo loved it, but PC Mag said the camera was shoddy and the UI is absurdly intrusive.

CNet liked the regular Zenfone 3 in a recent review. Though they too, thought the Zen UI was way too heavy. Seems to be a problem with some of the imported Android phones lately.

At this point I won't get a Deluxe unless it can be rooted, which I think is likely to happen based on Zenfone 3 progress.

It's the best thing you can atheistically look at. Battery life will get you one day of strong usage. Which combined with USB type-c that's nothing to be bothered by. I'd give the overall phone a solid 8.5 out of 10.

Battery life is terrible.
The same apps I use with no issues on other devices (including other sd820) cause a severe battery drain on the z3d.
My guess is the power management policy in the HAL, framework, or issues with the scheduler on the kernel level.
Initial investigation points to communication apps (Riot, Conversations), which cause a lot of wakelocks (then again, no such issues on other devices).

Once (& if) we have a bootloader unlock, this will be one of the first topics to address in custom kernel builds or custom rom builds.

I go ten hours at work with 2 plus screen time, 30-45 minutes on phone, 3 emails syncing, Facebook, instagram, Snapchat, two phone numbers, and I leave with 50% battery.

I'm in the same boat as mostly everyone else here. I'm heavily on my phone while at work as well (roughly 6 hours of constant use on most days with heavy internet usage as well). I stay at work 2 days in a row every 3 days, and in that time frame, I still go home with 30-40% battery still left on my phone.

If I were still using my note 4, I would have had to put the phone e on the charger twice a day for both of those days.

Plus, with the dual SIM feature, I don't have to carry around a work phone. My boss was more than happy to get me a nano SIM for my pho e when he found out both my work phone and personal phone would be one in the same and easier to contact.

So yeah, with the above stated, for me, the battery life is way better than what I have put up with on the note 4 for the past 2 years.

Battery is great for me. I don't have a SIM yet but use Google hangouts/Voice# and am constantly on my phone browsing and using different apps. I charged it 7 hours ago, it has 3 hours of screen on time so far, and battery is at 57%. It says it has 9 hours left (based on my current rate, I will probably hut around 7 hours of screen on time. That is on High Performance, though also without a mobile network connected. I am constantly connected to and using wifi though and location is on too.)

Plus with QC3, my phone charges from dead to full in an hour. It is crazy fast.

Edit: Correction, I am in Power Saving mode as I guess I clicked into it when prompted last time my battery drained and forgot to switch back. Didn't notice a performance difference though so maybe I'll stick with this mode until I play a game. Next time I recharge, I will put it in High Performance and record my Screen on time then.
