Battery life S7+ - Samsung Galaxy Tab S7 / S7 Plus Questions & Answer

While using the Tab S7+ for almost two weeks now, I consistently get approx. 6 hours of battery life (that is with the screen on 60fps, half brightness and mostly using office applications like Teams, Outlook, etc.). With the huge battery included and some reviewers indicating they are getting up to 10 hours of use, I'm not sure if I have some issues.
What are your experiences with respect to battery life?

My screen on time is very good. Can easily get 10 hours of SOT for light browsing etc. A bit of video here and there.

Thanks! That doesn't sound too good for me

I just have my tab s7 plus. And I get 6 hours and 20 minutes out of my battery with the screen set to 120 hz. You know when your screen is set to 60 hz when you go to settings - display - motion smoothnes is set to standard. I am right now testing how long my battery last when my screen is set to 60 hz. If you want to know which apps are draining the most battery life. Go to settings - device care - battery battery usage. For its Google chrome

Just tested it and I can do 8 hours and 50 minutes on one battery charge while the screen is set on 60 hz. It's not as good as the reviews say on YouTube. But largely better than my very old samsung galaxy tab pro 12.2

It could be a manufactory flaw. But it is more likely that there are several apps on your tab that are draining your battery.

Mine is not a plus, so not sure if this is helpful. I get 10h from around 86% charge (I don't (dis)charge 0-100).
Mostly Netflix and video calls on wifi, some browsing, reading, and note taking.
This is with 60hz, and battery save feature which is supposed to limit max charge to 85% (Though that feature is questionable from what little testing I did.)
Check what apps are draining your battery. It's not necessarily a manufacturing flaw.

I am from India and i have the note pro 12.2 lte version which crazily enough i use as my primary phone. I have data enabled all the time with auto brightness mode on. I use the Galaxy Note 7 ported ROM for the P905. I use my note pro 12.2 to watch a lot of youtube videos, whatsapp chat, browse the web, checking and sending emails, reading word and pdf work documents, 30 to 45 mins of playing asphalt 8 and into the dead 2 and answering/making 4 to 5 voice calls a day. I get a solid 8 hours of SOT even now when i get the low battery alert at 15%. I got over 9 hours of SOT on Lineage 17.1 android Q but found the features too limiting compared to touchwiz and i missed the spen. And that is battery life on a 6 year old device. I do make sure to not charge it more than 90% and i .com not let the battery dip below 15% before i charge it. I guess i got lucky and got a tablet with a really good battery.
The tab s7 plus has almost the same size screen but has the major advantage of it being amoled versus the lcd screen on the note pro 12.2. Plus with the new power efficient cpu and a 10000 mah battery, i am surprised at the battery life most people are reporting. I guess being than thin comes at a price and there is less power generated mah for mah compared to the 8.8 mm thick P905.

Just got mine yesterday. The battery life is significantly better than that of my Tab S6. I'll see how it goes over the next few days.

Don't know exactly in SOT but working from home, I charge it once a day and am using it constantly from 9am till 11-12pm

I've change the changing procedure to slow. No fast charge, slowly changing and stop at 85(?) Prozent...It will be better for the battery lifetime

There's an in built option to stop charge at 85%. Though from my testing I don't think it's functional really.
I've checked the voltage on 100% with both on and off, and the values were the same.
Maybe someone who has it off could measure the voltage on 99-100 charge? Would be nice to comparte results.

We run CCleaner Pro 5.1.0 [for Android] set with max battery life and automatic cleaning mode. One of the useful functions is a 1-click Boost which puts to sleep/closes apps in batch mode. Appears to help with extending battery duration as we've run 5 days with everyday on/off use (messaging, browsers Dolphin, Puffin, Vivaldi, etc) between charging.
Also set maximum battery charge limit to 85 percent from Settings > Charging > slider button to On [85 percent]

I am a complete noob to the art of monitoring battery heallth & charging, not even sure if my question needs a new thread.
My S7+ has been in use for about 2 weeks. The first day, I charged to 100%, then enabled the 85% charge option and also installed Accubattery and set that to remind me to remove the charger at 80%. I have charged it only up to 80% ever since, on a slow charger.
Today, Accubattery Battery Health is showing Battery Health at 83% capacity. Does this mean the overall health has gone down by 17% in jus two weeks? Or do I need to learn a lot more about meassuring battery health, and if so, is there a dummy's guide anyone can point me to?
I bought it direct from Samsung, haven't made any ROM changes and am using the stock launcher. Love the tablet.

You can see the difference in AIDA64 Premium 1.74 [Android] (set to 100% > charge to full > set to 85% > reboot > charge to full)

Bro, thanks for the Aida64 tip to see the real battery capacity.
It says ( Reported by android ) 9800 mAh
and ( From Database ) 10090 mAh
Was wondering how to see if this samsung feature was acualy working.

What exactly am I supposed to be looking at there?

I have the same issue here. I even went as far as to ring up Amazon and get them to send me a second one as my battery must be faulty if its only getting <50% (6-7hrs) when its advertised to run for 14hrs.
Upon receiving my new one. I did various battery stress tests and found that the new one had an even worse battery than my old one.
(Bare in mind both of them are at factory settings).
I did this test for about a week apples to apples comparison, then eventually returned the new one as my old one (which is only like maybe 2 days older lol) performed better in every single benchmark as well as battery.
So I either got really unlucky receiving two units with bad battery or this is just the norm?
EDIT:
Upon doing a quick google search; it seems like this is true across the board.
https://uk.pcmag.com/tablets/128966/samsung-galaxy-tab-s7
5hrs and 28 mins according to google and this article
Either way, i've noticed if I play a video, it roughly loses 10% per hour; but when browsing i can easily lose 10-11% every 30 mins.

ATT version of SG2 sucks your battery?! *Fixed*

Update and FIX!
My phone is no longer draining massive amount of batt life when idle (3-5% after 7 hours of idle), android system usage is now down to 5-15% instead of 78-97% from before.
My fixes.
1. Turn off data syncing
2. Turn off wifi while on the road (so wifi doesn't constantly look for signals).
3. Clear memory
Yes, att installs a lot of bloatware that constantly update for changes.
If killing those services AND disabling data syncing doesn't help your problem, then you have a kernel problem (like myself).
If this is the case, do the following:
1. Take phone back to att and get a replacement
OR
2. Re-flash your android with the STOCK kernel found here
http://forum.xda-developers.com/showthread.php?t=1286432
OR
3. Reflash with cognition x2 (reported to solve a member's problem, I didn't try this myself).
NOTE** This will root your phone, you will NOT get the exclamation mark during boot up, but kernel counter may be at "1" after this process.
Re-flashing my phone AND applying the three tricks I mentioned above worked for me..finally my phone is no longer crippled with crappy battery life and recharging is A LOT faster now.
I must be going crazy but this sg2 is killing me. I got it from Att yesterday and the battery life has been pretty HORRIBLE. (First time android user btw).
The phone will eat up 10% of my batter life after only 90 mins of idle. I checked the battery usage and Android OS is at around 78%!!! How do I fix this problem? I downloaded OS monitor and didn't really see anything that uses a lot of CPU, except for certain files syncing from time to time (but 2-3% usage usually).
Checked with battery spy and apparently the majority of the time, the phone was hovering around 200mhz 70% of the time and not deep sleep.
It's sad to have only 1.5 hours of display time with a battery of 45% left (7 hours total time)...coming from an Iphone 3gs, this is just unacceptable. I almost flashed to the 2.3.5 firmware but noticed it's NOT compatible with ATT's version of SG2.
I see people who have a total time of 2 days AND a screen time with 3 hours with 30% battery left. I wish I can get half that!
Running on 2.3.4, can't be the infamous drainage bug right? Thought that only happens with the 2.3.3s
Wifi on, application sync on, GPS off, brightness at 25%, using live wallpaper (the windmill). No active apps on. Downloaded aim, epocrates, battery monitor, cpu spy, and os monitor..rest of the apps are stock.
Update
According to my CPU spy
For the past hour that the phone was in idle
2:20mins at 1200mhz
4:52mins at 1000mhz
8:33 at 800mhz
1:28 at 500mhz
10:11 at 200mhz
33:36 in deep sleep
Currently Android CPU usage is @ 97%, display time of 7mins(2%)
2h 30mins since last charge (97% charge)..current power is 79%. Did nothing but idling and checking battery life.
So...that's 30 mins out of the hour in which my idling cellphone was hacking the pentagon....
Also the cellphone is a tiny bit warm to the touch (not cold)
I have 35% battery life remaining and have been unplugged for nearly 11 hours. This is significantly better than what I was getting with a Thunderbolt on Verizon, where I was needing to charge after about six hours of use. 11 hours and 35% remaining isn't the best in the world, but it's only been two days. The phone needs a few days to charge and discharge to determine true battery stats and will probably get better.
Being that this is your first Android battery life will not seem great but let it settle in for a few days it should get better.

Used Nexus S, LG Thrill, Samsung Focus, Infuse, This is the best Android phone for battery. I have 40% left with normal use (emails, calls, music, read news) at the end of the day. Huraaaaa

If you only got the phone yesterday, its way to early to make any judgments on battery life. Battery needs at least 3-5 days to settle in and build consistent battery stats.
Also, what are you settings? Auto Brightness, Bluetooth, GPS, auto syn(exchange emal, gmail, facebook, etc). If your not using these, they should be OFF. It's easy to manually refresh email, etc.
I've seen some people reporting very high Android OS(over 50%) but still getting solid battery life.
I'm at 1hr display time, heavy texting. 72% left, been unplugged for 12hrs
no people what this guy is talking about is the android os bug. i have it too. hopefully an upgrade or different rom will fix it. my phone has been unplugged 11 hours with only 1 1/2 hour display but android os has ran for 52 minutes and now im at 32% battery life. once this bug gets worked out the battery life will be amazing.
I don't think that there is an android OS bug. My android OS shows as being 42% with 13hrs of moderate use and I am still at 67% battery remaining. This is by far the best battery use I have ever experienced on an android device! My cappy would not even come close to this performance and this is on stock ROM and kernel.

I'm very happy with mine, this was the first total drain on a new battery so I know it will only get better.
Total time: 18hr 25min
Display time: 4hr 48min
I think it's the system os, not the hardware. There were a few times when the battery didn't discharge itself at 7%/hour (had it idle for 3 hours and it went down like 2%).
And yes, everything is turned off except the sync app data and wifi. There's no option to turn off 4g btw. It's just weird how sometimes it's in this mode of power drainage, and then sometimes it doesn't drain much..but most of the time, it's draining.
I seriously doubt the phone can only run 2.5 hours worth of heavy usage or 12 hours of standby (it should last days!). If this is "normal" for android, then maybe I should have a visit back to att and exchange for an iphone (and I really don't to!)

I agree - as I said in the Android OS drain thread, even in "good" situations, Android OS displays way high on our systems. I think it's a reporting bug.
I dropped 2% in 5.5 hours completely idle (sitting on my shelf) last night - Android OS was at over 60%. It seems that so far for me, the higher it is, the better my battery life is.
I drop around 15-20% in 9 hours of being mostly idle at my desk at work - it's a weak-signal location so the radio eats much more battery.
One thing is that unlike first-generation GalaxyS devices and interim ones like the Infuse, the GS2 has a coulomb-counter type of battery gauge. This type of gauge sometimes needs to be calibrated with multiple charge/discharge cycles or it will misreport battery state of charge. (However, when calibrated, it's much more accurate.)
Edit: I do have some power management tweaks in the kernel I'm running, but they don't make that much off a difference except in some high-drain corner cases in my experience. I'll be releasing it sometime later this week depending on how well these antibiotics do their job.
Do i need to install a battery app to see the percentage? or we have a way?

If you see "DataTracker-FD" or "Fast Dormancy" as the top wake lock, go into dialer
dial *#*#9900#*#*
disable Fast Dormancy (FD).
By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.

That applies to the I9100.
As far as I can tell, the I777 has FD disabled by default. (This may change once I9100 ROM ports start showing up)
Okay, charged my battery to 97%(I got a beep saying it's fully charged). Idled for the past 2 hours and 22 mins. Battery is at 86%.
According to the battery, my screen account for 2%, and the android system accounts for 97%.
This is a stock phone guys, I have no apps installed!

Just search up "battery indicator" in the Market and you'll get a few to choose from.
I too got mine yesterday and started tinkering around with installing apps and such to test out all functions before I rooted it and move onto cm7 most likely. The 1 things I noticed was that the battery was NOT completely full when it was first turned on at the store so once it got a little lower after playing with it I charged it up overnight. Today the battery was WAY BETTER and was not dead yet. I have been using it NON STOP today, rebooting it, testing it, trying to root it, rebooting some more, some time using tango to test it out, watched a Netflix movie, pretty much taking full advantage of it all day. I finally decided to charge it up and use my Captivate a bit. I didn't keep track of usage and times today but I KNOW it lasted a WAY LONGER time with all I was doing with it than my Cappy. Tomorrow I will check more out possibly before putting on a rom.
So LOOOONNNNGGGG STORY short make sure you charge it up once you get it before messing with it too much and then it will LAST LONGER.

After two nights of completely draining then recharging the battery to full, the battery has gotten significantly better. I'm trying to drain it again before I go to bed tonight but I don't think I'll make it.
I played the entirety of Toy Story 3 on max brightness, and only burned 20% of the battery!

why is the battery life so poor?

I got an LG G5 2 weeks ago and the battery has been outrageously bad. I bought it used and the owned has owned it for 2 to 3 months. There is very little standby drain and the phone is cold to the touch within minutes. Overnight drain is around 10 to 12 percent with always on display which is normal considering the 1 percent per hour loss plus the normal overnight drain. However when I turn the screen on the screen on time is very poor only about 2.5 hrs to 3 hours. The screen brightness is set 20 to 40 percent no auto brightness. There appears to be nothing draining the battery with the screen being the biggest battery draining. I have location nfc Bluetooth and LTE turned off. Along with touch sounds and touch vibration but toggling these settings makes no difference. Its impossible to find out more because I have no root. If this battery continues to be this poor I'm going to be selling it because I cannot stand having to charge twice a day even with quickcharge 3.0 old xiaomi redmi note 3 lasted 2 to 3 times longer on the battery. Any ideas what could be eating my battery?
Hi
I get 4 to 5 hours screen on time and I use my brightness at 75% to 100%, never as low as 20-40% it's too dark.
What apps do you use when you do have the screen on? Maps and games will drop you to 2-3 hours screen on time like all phones, but normal apps (excluding snapchat) will give you 4-5 SOT.
I would turn off always on display, you won't miss it.
Eeeeh , your Android system and android Os are high , screen should consumpt most of the battery about 30-40% mine does 34% with 35% brightness and Phone idle 22% my android system at 9% android Os 6% , if you dont game you get nearly 1 day life from your battery but if you do you need 2-3 timers charging per day , also if you use Data it just sucks the battery like vacum. So there is a drain in your system but its true lg g5 consumps a lot in order to give you performance in priority and not power saving. Dont forget G5s are the only high range phone that you can swip your battery with no deal , they are giving you that feature , Use it!!! You can grab up to 3600mah (2800 stock) extended capacity battery with a wall charger from ebay really cheap and never again have a battery problem. Also this batterys are lithium ones , i saw in your pic 10% i suggest not to go below 20% you are killing really fast lithium batterys if you decharge them!!!

Always on display barely drains any battery. I use apps such as facebook, text messaging, messenger, instagram, chrome, etc. I rarely play games because the second I open a game the battery life is only about 1.5 hours sot.
Well Facebook and messenger should be a couple of alarm bells when talking about battery life surely? Also, you bought it second hand, you have no idea how the previous owner treated the battery in the time they had it no matter how short a period it was.

Hello friends
I have a problem with battery and also unable to turn on the WiFi after update.
I just bought my brand new G5 H860 TWN and updated it, which cause the whole device to malfunction.
please correct me if I'm mistaken. An update is meant to improve the functionality of a device not to destroy it.
Apart from this problem the interesting thing is that non of the LG customer cares know whats causing the problem,
A word of advice to LG. Please Do not make something that you don't know **** about.
yours sincerely
have nice day.

Thanks for your advise my friend, factory resetting the device was the first thing i did, but i did not solve the issue.
i have tried the following:
-Flash other ROMs from different countries for H860
-booted the device into safe mode and tried to enable the WiFi and etc.
my WiFi MAC is set to 02:00:00:00:00:00 and it means that WiFi has not been detected by android. Also the Bluetooth address is defined as "unavailable".
and the worst of all is its battery drain issue which kill my battery within 5 hours in standby mode, while i can not notice any abnormal battery consumption in "BATTERY USE DETAILS" section in Battery usage setting. this probably means that some other consumer(perhaps the WiFi) uses the battery without being listed.

H860? H860 haven't got root nor custom ROM yet. Bootloader of H860's still locked.
I've got a brand new LG G5 which I have been using since Thursday and I honestly can say it sucks big time compared to my 2 year old Z3 which can easily get me 4 hrs SoD on mixed usage. Using the exact same set up of apps, location and wifi/mobile use, I am struggling to see more than 2.5hrs SoD with the G5. Honestly, it just drains battery like no tomorrow and this is fresh battery... I dread to think what it will be like in 2 years. Sony made a lot of mistakes but the Z3 really excelled...

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 Google Pixel 3a before depleting the battery.
Then, drop a comment if you have anything to add!

You got 8 hours on the regular one? I used to have the 3A XL but then gifted it to someone and an now using an galaxy S9. Really miss having a pixel though so am thinking about picking up the regular 3A and was wondering how the battery would differ

Yes it's the 3a. I think i could get more SOT without gaming.
From full charge to zero, I could get about 10hrs of screentime consecutively browsing, but that's not how I use my phone. In 48hrs of 'normal usage' I get about 5hrs of screentime.
I do about 3-6 hours of BT audio streaming daily which is why there is a larger than normal screen off usage. Still nice average SOT. I have so many sessions because I try to keep my battery between 50 and 80% for longevity.
I get 8 good hours.
What does Android 10 Battery say? Screen usage since full charge? Also Full charge lasts about???
Mine says 1 day 11 hours of typical usage. I always charge at night so it has rarely if ever run out.

Well I switched back to the 3a (regular version this time not the XL) and I'm getting about 4 hours SOT. Brand new.

Worse, on the best day you can get 6.5-7 hours on the regular. On the XL it's possible to get 9-10
I got my pixel 3a a couple weeks ago and struggling the last week or so getting more than 3.5 or 4 hrs SOT. I did use GPS for a 2 hour drive home today but it's 3p and I'm down to 10%. Idunno what's going on.
Here is the other day :/

the app usage of 66% is a clue. maybe you got some crazy app eating up battery. if you have bluetooth and/or wifi scanning on continuously that can drain a bit. gsam can be setup to show which app is using most by doing the adb command. just select apps for the details if you have not already.

Check out the second screenshot in that link. I've setup this via adb and had that included originally but probably wasn't obvious

Here we are after factory reset and flashing the latest OTA from
https://developers.google.com/android/images
Still can't hit 4 hrs SOT. Not once. I really don't know what to do at this point. Incredibly frustrating with everyone else on this thread having MUCH better results.
GSAM is showing some pretty beefy wakelocks on that "RemoteSoundTriggerDetection" and "*alarm*", ActivityManager-Sleep, etc.
I bought it from Best Buy. Should I go up there and see if they'll replace (highly doubt it) ? Maybe flash a custom kernel?
screen on time is a function of what a person normally does with a phone. one way to get high screen on time is you could set display intensity to 25% and timeout to 30 min. if you need that number to be higher. just let the screen be on as much as possible. when you first got it did you fully charge it then fully discharge it then fully charge again? screen on time is about the last metric i ever think about. i don't understand at all why it's so important. i'd be willing to bet some users set intensity to 20% and time out to 30 min or always on and do very little else then they get s.o.t. of 8-9 hrs or higher and think it's great when it's a joke. that's the way i look at it anyway.

Not sure if you're replying to me but I'll answer anyway. Yes I fully charged it then fully discharged it then fully charged again when I first got it.
It's not the SOT that is so worrisome but the constant Android system and kernel drain on my device.
I'm getting worse battery life on my 6 week old 3a than my 2.5 yo OnePlus 5 which wasn't good to begin with. This device was lauded for having excellent battery life and I'm not seeing it.

It isn't that at all. I found using it for anything where the phone needs to utilize the GPU a lot, like gaming, drains battery substantially. "Light" workloads, like web browsing, using social media apps, streaming video, etc give you really good battery life. Once I start up a game, I see about 5-6 hrs compared to 9.5 hrs if I just stream YouTube, check the XDA app, email, Reddit, etc.

Poco X2 Estimated Battery Capacity by Accubattery

So i regularly use AccuBattery app in my android device. It's a very useful one.
So i installed this on my new Poco X2. Those who've used it know that it can estimate your current battery capacity based on charge sessions and some other stuff.
And upon using it showed my Poco X2's estimated battery at around only 3800mah.
And a lot of users also are complaining about battery backup on flipkart.
Please check and post your device's estimated battery capacity via AccuBattery app.
Unfortunately, what Flipkart reviews say is actually right, this phone has serious SOT problems with 120 hz i only get 6.5 hours sot and 8 hours with 60hz and I don't even use it heavily just YouTube and small games with social media. This phone has very poor optimization. I know i shouldn't compare but if you look at realme 6 pro almost same specs but with smaller battery (4300) gives 1 hour more SOT even with heavy usage(both set to 60hz). This is absolutely disappointing, eagerly waiting for custom roms and custom kernels to make it as my daily driver. Will update you on the accubattery results

Thankyou, waiting for it.
Bafore this I was using standard China Rom with mine and battery was a mess. But I unlocked & flash MIUI.eu. I add-on "naptime" to help with Doze & using Universal GMS Doze magisk module. Managed to get almost 8hrs SOT with ads removed, bloatware removed & MSA removed. Maybe you should give it a try and see ?
Same
Battery is fine for me
Don't know how people here getting more than 3.8k mah estimated. Mine doesn't go above that. I'm pretty sure some units have battery problem as reported by few buyers on Flipkart. Some said battery is excellent while some said poor battery. I think poco x2 indian units are suffering more. Since after watching some tests on the redmi k30 Chinese variant by YouTubers they got significanly more SOT. I tweeted to them, no reply from their side yet ?
I got my K30 directly from China. No battery issues whatsoever.
I've been getting consistent SOT of 9.5 hrs on average with heavy use. SOT range for me has been 7 hrs (120Hz) - 11 hrs (60 Hz) on 4G LTE (you can check my post on SOT thread).
Being a heavy user, this battery life has literally blown me away and I absolutely love this phone simply for that. I can easily get thru a very heavy day with 30-40% battery left. I've been charging the phone twice every three days on average.
I'm on stock CN ROM (MIUI 11.0.13 Stable)
I easily get 8 hours + SOT with gaming. I play cod and pubg extensively.
Battery life update after using a month .
Mild gaming and social media usage.
Average sot is around 10hrs , battery lasts 30-50hrs depending on camera usage.
Unable to upload screen shot showing bad request.
Is AccuBattery reliably on first cycles? If many users have 3800 mah insted of 4500mah then something stinks here
My poco X2 shows 4398mah
I am on stock Indian rom miui 11.0.10
I did some quick research across the web and it looks like there are three types of d
1. Battery Drain issue devices, they have bad battery issues, battery capacity way below 4500 and widely varying with users. Screen off discharge is way off charts, like >5%/hr. SoTs varying around 5hrs or <5hrs
2. Inefficient battery devices. (Majority) They have battery capacity much below the specification, however less varying, always around 3800mAh. Battery doesn't drain that badly
I have this device, heavy usage like pubg clocks around 15-20%/hr, normal usage around 10%hr and screen off discharge rate at 0.5-0.9%/hr. Hardly discharges 2-3 percent through the night
3. Ok devices. These are the best sets. Battery capacity constantly goes above 4000mAh (still doesn't hit the required 4500 mark tho). No serious battery drain issues. (I don't know much about these devices because they don't look into the web coz they have no issues.

Usually i get around 9hrs 30 min sot on 60hz and around 8hrs on 120hz...( Without gaming ) after the update of miui 11.0.11 my phones battery backup gradually increased 1 hr on 120hz...+ I did some tweaks blocking system apps from running in the background
After using the phone for 8 months, I noticed that charging speeds have significantly reduced. At the beginning, the battery went from 0-100% in ~70-75 mins if I remember correctly (cross checked this with another review website).
But when I properly checked today (after a long time), it took 118 mins (2 hrs!) for the battery to go from 2-100%. I also plan to check this with the screen/phone off again.
The battery life is still great though, maybe slightly reduced compared to the beginning.

Original charger used and the cable is in perfect condition.
Re-tested today with the phone switched off and it went from 4-100% in 70 mins! So all is good. Planning to test tomorrow again with the phone switched on.
Battery life is still stellar. 8.5 hrs of SOT for 26 hrs of usage on 120Hz; 70% WiFi and 30% LTE.

Question Official battery life thread

I have the S23 Ultra since February 3rd and battery life gets better and better.
I don't know what to say. I think this s23 ultra is faulty. I can't be at 29% battery used with over 6 hours screen on time! Light use, from 80% charge
15 hours total uptime, 8 and a half hours screen off time, gotta sleep sometime. LIGHT performance profile used and screen at 60hz cause 120hz my eyes can hardly see. It's smoother yes, but barely, battery life is king for me
All on WiFi, location on, most apps sleeping. Gobsmacked. It's beating the redmagic 8 pro that's in the household with its 6k mah battery.
I'm expecting a lot less using mobile data, surely

Amazing battery
This phone is perfect
Got it since February 10th in the USA and I can only say battery has been great. Compared to my other phones ( coming from a pixel 7 pro and a Xiaomi mi 11 5g) the battery life is just excellent on this s23 ultra, for such a big device and huge screen size I think Samsung finally nailed it. No sleeping apps, not profile settings just plain stock and so far so good. Wifi and data on 24/7, location on 24/7, VPN 24/7 . The browser times where spent a huge time watching videos from it, almost an hour of video calling and shooting some video and photos, couple of sessions of gaming.

How much do you lose on standby? Say overnight, while sleeping, over 8-10 hours how much do you lose ?
My last check yesterday was 3 percent

Thanks, is that with WiFi data Bluetooth GPS etc off? How many hours standby did you lose 3% on?
The amazing battery life has a lot to do with the display too. It is a hugely more efficient panel.
Samsung gave the Galaxy S23 series a new energy-efficient AMOLED display
Samsung confirmed that it has fitted the Galaxy S23 line with a new type of AMOLED display that saves on power.
www.androidauthority.com
All on. Wifi. Data. Location. Bluetooth. Performance mode.
I'm so happy with this battery performance and am afraid to update OS when it comes out...Given the great track record of Samsung breaking things that don't need fixing, there's a high probability that the battery life will go for a toss
Had my s23 ultra since 7 Feb and consistently get just under 10 hours of SOT (most of my day is indoors on WiFi, with a 2 or 3 hours walk most afternoons in 4g)
I am running pretty.much on default settings for screen and battery - I just use my phone normally and forget about battery optimisation settings
This is the best battery.life EVER on a Samsung!
After 2 weeks with the 23u and my standard use of it i have from 85% to 30% (i never go below 30%) 4h SoT

I think it is ok. I use performance mode, all location, Bluetooth with watch, some 5G, some WiFi etc.
I mostly read on phone, scrolling...

Have you done anything specific in battery settings? Any debloating? Is this with wqhd + 120hz? Standard mode or lite mode? What's your battery settings ?

Yes I did debloat, light batter profile and battery saving (it's more than powerfu enough).
Plus I have disabled all the nearby services for smarthings find the phone offline wifi quick share etc.
I don't like having the phone always sending radio signals around for no reason

Can you give a brief list of what you debloated?
Also, android system intelligence service, is that even a necessary app? Would cause any issues if I disabled/deleted it?

Honestly I didn't track the changes, but I followed this guide
[DISCONTINUED] Samsung Galaxy One UI - Optimization Guide
THIS IS A SUGGESTED CONFIGURATION FOR SAMSUNG DEVICES OUT OF SUPPORT/CLOSED I - RECOMMENDED SETTINGS To Start With - Factory Reset before starting optimisations - Factory Reset after every Major update (One UI/Android) - Remove SIM before first...
forum.xda-developers.com
I wasn't even too much aggressive with debloating, maybe I'll go for a second round
