I'm really impressed by the battery on the A7. I've had 3.5 hours of sot and 20% left even after caning it with DS Audio, 4 hours of internet radio, 50 photos plus editing and lots of surfing.
Doze is extraordinary. Check out last night's battery consumption (I really must get to bed earlier).
Best battery life on a phone that I've had so far.....Well, since smartphones. I had some flip phones that could last a week.
It seems to be a bit better than the Nexus 6P I came from. Definitely not as good as the Oneplus One, much better than the Moto X Pure.

The main thing I've noticed is that this phone doesn't get excessively hot which seems to kill the battery very fast (both issues I've had with almost every smartphone owned: Nexus 6p and Oneplus One included). Apps that use GPS, camera use, gaming etc don't seem to get the phone as hot and this seems to correlate with better battery life under use. The only time I feel the phone warming up is if I'm using the Quickcharge charger while doing something else. It's barely warm though.
If I babied my Oneplus One (Sultans ROM) I managed to get 8 hours SOT which was crazy but it didn't charge the way the Axon 7 does and it certainly wouldn't have coped with the stress I'm putting on the Axon 7. I remember things like constant GPS + Spotify + Bluetooth would mean my Oneplus One wouldn't be able to charge as fast as the battery was being drawn. Not an issue at all with the Axon 7.

I agree on all points. This is one of the coolest running phones I've ever used. Only thing I've done that creates noticeable heat other than charging is +30 minute phone calls on Bluetooth in car. And it charges unbelievably fast. Very happy!
Got ,5 and a half hours yesterday. I honestly average 5 hours. Battery life has improved significantly with this smart power voodoo on. It doesn't affect performance unlike it does on tw.
I notice more apps are closed in background when I have smart power on.. Like I'll be able to have about 5-10 apps open with smart power on.. But 15-25 with it off.
I get an extra hour sot with smart power on.
And I took quite a few pictures that day.. Totally thought I was going to toast my battery.. But it held up better than any of my samsung devices..
The Axon ZTE 7 A2017 has the most smart power!!! I dont have to worry for the whole day charging my Monster!!!
I agree with all the comments here the battery is really good, pair with fast charging if necessary is a winner !!!!
Same here I'm enjoying the battery life on this bad boy!
I would also say it's not too bad.. still 25% remaining after 5h DOT
Agree! On at 6:30 am and still at 86% - light use. 1 phone call, a few texts and 10 or so minutes checking the news. My note would have been 70-75% by midday with about the same use. Power save mode on both phones. Very happy with this phone.
I started this thread and I'm still pretty happy with the battery life but this evening I noticed the phone was a bit hot. First time I've noticed that. It drained from 45% to shutdown in 10 minutes. This is what my Oneplus One used to do. How can the same sh*t happen to the same guy twice?

Sounds like you've got a rogue app in three background that's forcing your CPU to max out and keeping it there even when not in use. There were a couple kernels on the oneplus one (including stock) with bugs like that, but it's not a kernel issue with the axon because otherwise others would have seen this. I'm betting it's a bad app.
I had just installed Kayak. Battery back up now. I'll see if I can reproduce the issue.
I cannot see the usage of apps. Any solution? I also can't see it in the system battery settings.
My buddy has this phone and literally flawless. i mean it works. it lasts. its powerful. has amazing SQ. and im over here with a friggin note 7 barely squeezing 16 hours out of it with3-4 hours DOT/SOT.
Not to mention XDA and everyone gets it wrong. its a 3250mah battery not a 3140mah

I use spotify or pandora via BT. we drove the same distance. same time etc. i lost 17% he lost 5%. both were fresh rebooted and waited 10 minutes. closed all apps and screen NOT in use. no wifi no nfc no nothing.
Can't wait for the battery life to further improve with android 7.1 and maybe even eventually a custom kernel
I'm getting minimum 6hrs of screen on time and i'm very satosfied with this performance
I have the base s21 on order due to arrive on friday upgrading from an s9. So far i'm yet to see any positive comments about the phone and is making me consider sending it back straight away and getting something else.
I would love to hear nice comments from real day to day users to hopefully sway me back the other way but with the camera, battery and chrome issues i've been seeing i don't know if i can commit.

The battery is good, just not on this latest february update. Before the update my S21 exynos had good battery life (6hours SOT on 4G, 7-8hours SOT on wifi). So we just need to wait for samsung to fix the battery drain this newest update caused.
Haven't had any of the issues others are posting, S21 (Snapdragon). Coming from 20+ battery not as good, but not seeing the drain others are complaining about. Very happy, even my Smart unlock works much more often, and finger print reader definitely better, but not near as good as my old Pixel. It was lightening. Loved the look of the old curved screen, but with flat, have less issues with case fitting and accidental swipes. Prefer the S21 size, I don't use my phone for games or Kindle, more as a phone and information center and controller for other devices. Oh yea, and a ton of music and Android Auto, wifi calling works better, even my screen saver when charging stays on now even though hits 100% charged. Glad I took them up on the "free" upgrade
The S21 Ultra is an all day phone.
2 Days for moderate use.

I haven't had an battery issues (Exynos) but I have been on WiFi all day, I have read the drain occurs on mobile data. I have been getting about 8hrs screen on time with 120hz at FHD+
There is a battery thread in P6 Pro section, but we don't have an equivalent here, so...
How's your battery on regular Pixel 6? Can't post any data from my side, as it's still being dispatched....
with my normal phone usage I am ending up with about 30-40% at the end of the day. With my Pixel 5a I still got about 60% juice. I cannot complain. I've seen wild differences on youtube from others (both good and terrible).
My battery life seems to be just fine.
Mine seems fine, it's been idle more than anything and it'll probably be that way since I try not to use it too much. When I'm at work I can't really use my phone anyway, so I expect battery life to be strong.
I also have a battery app that monitors usage and health of the battery if anyone is interested.

Yes I am. I only charged it once to 100 even though I know that's not good, but for first time I think it's ok.
I'm not sure i have enough stats to show since I've only used the app once to charge, but happy to share whatever info you need. Just let me know which screen to grab and I'll post.
comparison. Over 8 hours is pretty good.
I guess I can't complain.
Im getting about 9 hours of SOT. Using accubattery and this is while using youtube TV along with bluetooth (not using battery saver at all). The battery life is great on the pixel 6 pro and its a bit better than my s21 ultra.
proof
I'm guessing my stats are good? Idk where it got 4 sessions over the last 4 days from, but I installed the app yesterday and had it charged at 100% around 3PM. From then on I would use it randomly, mainly using chat through IM apps. I haven't done anything super battery heavy yet. I'm at 8% as I sit and write this...
Dayum. That's some iphone 13 pro max stats there lol.
It all depends on the connectivity, e.g. @android_dan is using 5G which is battery hungry, and also network reception is really low here.
I have huge drain from mobile network standby. View attachment received_785539938832034.webp
I tried many different things and seems that the problem is with esim card.
I hope they will fix that soon.

Even on 5G I have no complaints about battery life. I'm getting up at 4:30 am and going to bed at 10:30 pm with 20-30% battery. We've had some weather delays so I've been on the phone a lot throughout the day. No complaints here.
So I am using my P6 for 3 days and battery life is amazing when screen is on (I can get like 12 hour of sot if I would spend all day looking at my phone), but idle usage is pretty high for me - getting like 3-4% per hour while screen off on LTE, 2g disabled, AoD disabled.
Is anyone experiencing the same? Or maybe I still need to wait for Adaptive Battery's magic?

I get 5% drop over night while I'm sleeping and connected to wifi. All apps closed in the background. I don't think that's too bad in my case. Definitely let things "settle" after the first few days of use. I've seen lots of improvement in battery after having the phone for a week.
I tend to get thru a whole day no problem! I turned network preferences to LTE cuz my area doesn't have great 5g and I don't find it slow at all. And I'm on wifi most of the time anyway. At the end of the day I have somewhere between 7-9 hours SOT which is amazing! I watch lots of YouTube videos and listen to music throughout the day. Hope this helps!
for me, the battery is a tragedy, it drops in my eyes, I was able to get a maximum of 4h sot. On average, I have 2.5 to 3.5 hours of sot. I have a recommended 4G network set. I use 2 sim.

I am afraid that it will not happen, Google has always not paid attention to e-sim activities. Pixel 5 running 1xsim + e-sim lost animations, they never made it better

They're actively looking into the battery drain issue, and some folks have had success with doing a factory reset.
Google Issue Tracker
issuetracker.google.com
I was able to find out what was causing my phone to be active and never enter a deep sleep, which has improved the battery drain I was having. I'm still not sure why mobile network standby fluctuates on me; sometimes it'll be as low as 3% and others in the 20 when I'm not doing anything different at home.
Dear XDA members;
So, I've bought note 20 ultra a few weeks ago (refurbished, great condition!)
I've switched from Galaxy Fold 1 and from what I'm seeing, the battery life is almost 2x more horrid!
I've been trying to use it in order for it to get adjusted to my patterns, still, nothing special happened after weeks of usage.
I've tried everything - naptime + turning off adaptive battery; turning it back on and deep sleeping the apps, changing the settings for maximum battery life etc. Wiped the cache and reset my phone, still nothing. NOTHING helps!
I've even decided to buy a new battery! My battery life is still horrible. Based on the reviews, I should be getting decent battery life, however, it is about 2.5-3h of SoT... Idle battery drain is also insane...
I'm using android 13 and I've noticed that a lot of people seem to write that it's the problem.
Does anyone have any suggestions? Should I install some custom rom? If so, which one would you suggest?
I REALLY love this phone and I REALLY want it's battery to last for at least 4-5h of SoT...
Thanks A LOT in advance!
Best regards!
I think sadly that's normal for the Exynos phone. It was always the thing fro me, I've had it since November 2020. My screen and battery were changed a month before the 2 year warranty ran out, and with a new battery I still get around 2-3 hours of SOT
3h sot is ok!I still have ny N20 but iḿ using a Google Pixel Pro,new!and 3 h ,perhabs a little bit more is what it gives!I will keep my N20 ;its a mess what Samsung is doing!And this for many years!For example;my Note 3 or my Note 4 were wonderful Phones,realy!With new Baterys they can do a good job ,eveb in 2023 with Androis 13,they give **** of this!And so i quitt Samsung,leider!
So, day one, regular use for me, at 50% after nearly 9 hours! Thats a record for a Samsung device, for me.
Not sure mate how your, but my is completely disappointed, pixel 7 pro has 8h+ on display S23U hardly has 7.5h+
Not sure if just my usage is more hardly use but battery or maybe setup is different for me.
All turn on (mobile data, Bluetooth, WiFi, GPS, location, Nfc, adaptive motion, wqhd+)
3 hours on Spotify with Bluetooth speaker.
Yes I use phone for my work so most day on it.

I believe that but I use chrome for work (password) saved there is well and all saved tab I need.
But same usage and same apps I used on pixel 7 pro is well so was hope that will same or similar better then pixel.
I not have issue on pixel great battery etc just few thing piss me off on pixels and for work spen is priceless for me.

That's probably "good" (?) for the S23U, especially if not optimized. All Samsung's should be optimized for best battery life and performance. Either by Package Disabler or adb edits.
Even with a degraded battery that due to be replaced I'm getting 8 hours or so on an optimized* N10+; easily over 12 hours SOT on a new battery. Samsung's stock solution has been to use a bigger battery since the N20U, with progressively worse SOT per mAh in spite of what should be more efficient SOCs and ram... and now no expandable storage.
*unoptimized the N10+ was a hot running hog that got 6.5 hrs SOT. Optimizing nearly doubled the SOT as significantly increased the screen off time as well. Backup Transport was a major perpetrator.
I got 19 hours on day one. Today I'm at 43% after just under 10 hours with just under 4 hours screen on time

N10+, screen off, cell/internet service on with AOD set to tap on, I use less than .5%@hr.
With good battery I use a total of 6-7% browsing with Brave, again with a good battery. Display manual brightness of 30-40%
With a degraded battery which is at replacement time this is what I'm getting, most of which is watching utube vids.
No 5G or variable refresh rate display, power set to optimized. This is with a less efficient ram and presumably SOC. More significantly much less mAh capacity.

You must have had a golden sample SoC in the 7 Pro to get that kind of battery. 99% of us didn't and don't see that.

For P7P, I find it varies wildly by ROM. Stock is a good middle ground, I think the best so far for me have been the AOSP-based ones with Gapps.

I was about to comment the same. I never got that kind of SOT on the pixel 7 pro after three months of having the device max would be 5 1/2 probably six squeezing everybit of juice. Good device but for battery the s23 ultra is giving me way more for the same usage no optimization.
I think by enabling the light performance profile, the device becomes a battery champion

Yeah I will say the February beta has had me going 39h off the charger with 5h SoT but that's largely been on wifi. I know from messing with my OnePlus 9 that it doesn't *have* to be super draining on LTE but I've taken the Pixel out on a day's outing and had it lose 50% in 3 hours on LTE/5G.
I've "upgraded" from the Fold4 in the hope that battery life would be much better. I'm blown away by how long this thing lasts!

SoC upgraded with a better power-efficiency, far smaller screen surface to power and also 600mha more on the battery. An other outcome would have been surprising.

Whole heartedly agree. My usage on the Fold4 - I hardly used the internal screen (I know, I know!). Comparing external screen use alone, this thing wins night and day. Surprising in some ways because of the resolution and pixels being driven vs the fold4 external display, but as you say, more efficient SoC coupled with a slightly larger battery must be working its magic.
Standby drain overnight is something else I've noticed as being much better too.
Early days, but I would charge my fold4 sometimes as much as 3 times throughout the day. This thing comfortably lasts a full day with many hours of screen on time and has battery left to spare. Amazing efficiency gains considering the short time frame between the two SoC's.
Mine is still optimization but so far looks good. Day 2 of use. Far better than my S22U exynos.

Second full day of usage, include setup cameras and work
Again 3 hours on Spotify +Bluetooth speaker, all turn on GPS, Bluetooth, WiFi, 5G + WiFi etc it's little better then yesterday around 8h+ on display still has 6% left.
Hope will possible on my use 9h+ on display.

Nop, I got problem on pixel 6 pro Thst was big issue and charge phone 3 times a day but pixel 7pro its really similar battery like S23U right now.
It was 8h+ on display and all turn on and max resolution.
Big issue is on Bluetooth wasn't work with my huawei watch 3 pro they block it.
Not sure maybe is my phone some premium to have that but I seen better then my also.
Latest. Everything max. Bluetooth and location on all time. Poor cell reception at work. Streaming radio on commute. So impressed with this. It blows the 22 exynos away.

I mean I guess if I use my 7 Pro straight through I can get 8 hours pretty easily as my average screen on usage is 8%/hr but the standby time is awful, like 2% drain per hour. This is all on wifi too. If I am on mobile network, I'm looking at 12-15%/hr screen on and 3-4.5% standby drain. I can't wait to have the more efficient modem in the S23U.
