How can I improve T713 battery life?

I got my S2 Tab wifi (T713) a few days ago and I'm kind of disappointed with the battery life. I've got around 6-6.5h SoT with battery saving in the last 30%.
I'm still on stock, should I root and slap on LineageOS 14 or 15.1?
Thanks in advance

Depends what you're doing. Check your battery usage and see if you can identify what's the highest drain.
I just checked mine: 3h38min used 34%, so that would project out to 10+ hours SOT. This is reading / web surfing with screen brightness at about 10%. Gaming or bright screen will cut that down, of course, but it's the best of any of the tablets I've owned.

Thanks for your reply, but you ommited one crucial information for me - on what ROM/Android version are you?
Also that is really bad way to estimate battery life, please provide some numbers when you hit 5% battery.
My main consumer is the screen with ~35% battery usage.
I use my tablet mainly for reddit (sync for reddit app) which is a mix of reading, gifs and videos, but mostly reading and for YouTube.
I tried setting the screen to lower brightness but I wouldn't use it lower from 25-30%, I don't want the whites to be greys.
I'm wondering if LineageOS would improve something, or maybe rooting and applying ad blocking to the stock rom.
I'd also like to apply a dark theme.
It's still under the warranty, it's a week old, so I'm still figuring out if voiding the warranty would be worth it.

I would keep it stock and enjoy it. Over 6 hours of screen time is actually pretty good. Did you use it straight for those six hours? Do you have sync, nfc, gps turned on? Any apps that continuously refresh like weather, email, or other games, etc.... Battery drain is very subjective. I use my tablet for media and gaming. I find it difficult be productive on this tablet. I own a Surface pro and battery is terrible, but great for productivity.

Yeah, I'm going to stay stock - I managed to put SABS on it so I have ad blocking and I can disable the Samsung bloatware so I hope that will improve battery life overall.
As I said in my previous post, I use it mostly for browsing, very rarely for gaming and I know games drain the battery a lot.
My gps/nfc/bt all is turned off all the time.
Only wifi for browsing.

I have Lineage OS latest on the Tab S2 SM-T713 and if you do gaming on it, it will be miserable, barely two hours of SOT.

Anything over 5h of SOT is good for this tablet. Samsung took the decision to sacrifice battery in name of weight, (or lack of it.) For me, this was a great decision.
If you've just bought this, consider returning it and looking at the Huawei M3/M5. The Mrs is a power user and get around 8h of SOT.

CLT-L29 battery performance

Hello,
I've just bought a dual sim P20 Pro a couple of days ago and I am unhappy with the battery.
With moderate use like some Chrome browsing, some sms, calls and a bit of facebook I am getting only about of 26 hours life from 95% to 18-20%. I am only using one sim with LTE network.
Two times I've had a sudden drop from 96 to 91 percent and usually when screen is online I can observe percents dropping one by one in a matter of minutes.
If SOT is like 5-10min it is always 1%, if more than more. Could you please give me advice or share your experiencies?
I've read some reviews than phone is like a monster with battery lasting 2 full days with heavy use. So i would be glad to hear your opinions.
Authorised service centre haven't found any problems when I delivered the phone to them.
Thanks in advance!

No phone will last 2 full days with heavy use, if heavy use includes calls etc, no matter what they say. Download battery app and check for wakelocks. Probably some app keeping phone awake. Edit.. Try this https://www.google.com/url?sa=t&sou...FjAAegQIARAB&usg=AOvVaw3cuTBnY1K_02fdd-kpZpug

Go to Settings -> Battery -> Battery Usage and check what drains your battery. Usually it's bad cellular network reception (you will see more "Cell standby") or some app.
I charge my phone every ~36 hours, but I'm not really a heavy user.
Just a note - AOD (always-on-display) does drain your battery (yes, OLED display, black colours, bla-bla-bla, just test yourself), so if you want it enabled (because it's convenient, I use it too) keep your phone face down on your desk/bedside when you don't need it.

You are not alone as i have the same issue but mine drains overnight. I guess warranty will fix it?

Mines been mostly positive from the off, coming from a Oneplus 5 this phone had a lot to live up to.
Honestly it really depends on what you have installed and what your reception is like, remove your SIM and see how your battery lasts then, it's quite the difference.
Seeing as no one would do that and you won't be able to move your cell towers then it's apps.
I can't speak for Pie as i did not want to install it until there were some decent roms available and maybe a working TWRP.
This is the thread i made on the oneplus 5 showing where i was able to achieve 14 hours 30 mins whilst at home and a leaderboard showing other peoples longest SOT times with proof.
https://forum.xda-developers.com/oneplus-5/how-to/screen-time-leaderboard-post-longest-sot-t3780178
Similar situation on my p20 pro but the SOT was 17 hours + over a weekend, so Friday - Sunday on 1 charge.
Average around 8-10 hours, 1 and a half days give or take/.
So depending on your usage / location / signal / apps it is more than possible to get ridiculous battery life and longevity.
Personally i'd say do the following:
Don't charge overnight (contrary to common belief, this does have an impact over time)
Leave sync on (maintaining synchronization uses less battery than a big sync)
Check your apps, Facebook / Snapchat / Viber, they're all hogs, use the web version of FB and stick with whatsapp, it's more efficient.
Remove any apps you aren't using.
Avoid any apps with ads on if there's a paid for variant.
As @purple patch has said, use BBS to diagnose if any apps are keeping the device from sleeping.
That's pretty much all i do.
Hope this helps.

I am wondering how are you guys getting this top performance. For me it is like a typical situation: 26 hours after charging to 93%, 22% charge now, 4 hours SOT.
Cell signal is good, using Facebook and Messenger a lot.
But let's see I will try your reccomendations. Thanks.

Facebook and messenger are major hogs, use the web version of facebook and you'll see a benfit.
Facebook harvest so much info it's insane, tbh i uninstalled my FB and deleted my account, got to be honest the only thing i miss are the little funny videos that people post.
Beyond that i'm glad to be rid of it.

battery or software problem??

I am software version shown in ss
I just bought the phone and only getting sot 30 mins for 10% of battery consumption i got like 4 and half hour of sot for 73% battery consumption i thought x2 pro have around 8 hr sot help me it's frustrating

Well that calculates to more than 6h SOT, which isn't that unrealistic if you used 4g and max screen brightness all the time, but there might be something draining the battery. Check the usage details. I see you use something connected to bluetooth so that might be causing the issue.

Bro i was using the brightness at 27% and nothing was connected to the Bluetooth

I installed betterbatterystats (bbs) xda edition and gsam battery app with adb rights. So you can see the deep sleep with bbs and the times of dot/phone time/ect and which app use how many ampere.
In this charging time I get 4,5 hours dot with 40 hours phone is on. I have now 34%.
Debloating, netguard firewall, no energy saving, always 90 hz.

Also i am having fps dropping issue during online gaming like pubgm or codm
What should i do to get normal 60 fps as this phone has 855+ so i can get 60 fps normally

I'm having even worse SOT and I have the same realme ui version.
I'm not as much hardcore user as a lot of you and looking at 4k mah battery I thought that I will be getting at least 7h SOT.
I'm not playing any games, right now most of the time phone is connected to wifi. What should I do? Debloat my phone? Is it somehow dangerous for my software? Can i ever go back to normal version?

location services destroyes battery on this device
i disable it for one day just to see the difference and it went from 4 hours SOT to 6 hours plus
always talking full brightness wifi some 4g 90hz
and from 100% to 1%

You have like almost 30 hours of standby, and if you use always on display, then that's at least 30% on that. If you consider this then it doesn't look that bad. You do the math. The other guy's stats concern me more.

You will need to make some adjustments, battery can be excellent but you have to be realistic,
Check out App quick freeze and freeze the apps you don't use.
Dark mode,
AOD off,Screen light effects off,
You just got the phone,tinker with it a while to see,
Also battery will drain a lot when your setting up the first day

Question [Help] SOT

It is my second day with the phone. Exyons version. I charged it 100% and left home at 5pm and here were are 11:40 pm 21% with 2hours 44 mins SOT
How?
4g enabled about 40 mins
I only used camera, google maps, a little facebook and uber.
Bluetooth enabled for the watch and the buds.
No wifi. No nfs.
Adaptive refresh rate and 1080p resolution after it dropped to 60%.
What have I done wrong?

This is very similar to my situation but I have snapdragon version my SOT is not that good get about 2-3 hours with 8 hours of use. I already resetting my phone once I'm currently still going through the learning usage pattern after my reset. Hopefully it improves because I'm hoping that my phone is not defective.

I thought about resting the phone but I have already downloaded about 20gb of games :/
I will wait couple days to see maybe the phone is still learning usage pattern . Please keep us updated if SOT got improved with you

I sincerely advise you to do a factory reset, don't restore any data (except stuff like picture and video) and start again installing apps, don't install everything, just the necessary and check the battery, you will see a big improvement.
start from there and then look at the difference.
different apps can behave differently.
And of course put anything you don't constantly use to deep sleep in battery setting!
I did it and my battery now is totally fine.

Question for you. What is normal battery draining for you. For example, if you leave your phone over night usually how much percent does your phone drop. And how long does it take your phone to drop by 1% obviously this last question depends on what app you're using but ideally on average how long does it take your phone to drop by 1%. The reason I'm asking is Because I kind of want to gage how my phone Is performing compared to others. Thanks!

Yea what's been said above, don't use smart switch and give it about a week to settle in, you will genuinely see an improvement.
Put all apps you don't use regularly/ need notifications from in deep sleep. If you have crap signal at home turn on WiFi calling. Turn off nearby decide scanning in connections.
If you're still struggling after a week, download GSAM as it gives much more detailed stats
I lose around 0.5% an hour overnight on standby

on average I lose 0,6-0,7%/h when the screen is off and an average of 10%/h when the screen is on.
fhd+, bt with smartwatch, location off, mostly on wi-fi (when I'm on wifi I use a Bixby routine to turn off data and switch to 2g but I don't think it makes much difference), lots of apps to deep sleep but not apps like whatsapp telegram and gmail.
anyway, everything depends on your specific use and apps installed but I can say my battery life was half than now when I restored my settings and apps data using samsung stuff.

Thank you. I will do a factory reset and update you guys later

I heard that uwb application is the culprit. Many users reported worst battery life with it. It's something related to 5g ultra wide band. Hopefully future update fixes it. Check below thread on how you can remove it. Not sure what functionality gets impacted by removing it
What is Uwb Application and how do I stop it??
So this morning I noticed this app I've never seen before, Uwb Application hogged 14%. I've never seen it before. What does it do and how do I stop it? I recently installed microg and YouTube vanced? Does this have anything to do with these apps...

FHD+/120hz/5g off/smart things off/ everything else normal
Overnight loss is about 2-3%
From 100% to 99% withing 3 minutes after wake up in the morning. That's turning screen on checking Facebook, or browse news.
My Huawei P30 pro would go 99% probably after 30 or 40 min of morning browsing
iPhone 12 pro max I am testing now, stays 100% for about an hour fr a wake up, that's browsing internet social networks

To measure battery loss from 100-99 is meaningless. The last several generations of the iPhone have behaved like this but clearly this has no real meaning, Which is more accurate? From that clearly the Samsung is the "least worse". To stay at 100% for an hour is absurd. BS calibration. Similar for the P30 Pro. Overnight loss of 2-3% is par for the course (I lose -using GSAM Pro - 0.6% per hour overnight which is probably very similar to you) So ignore a 1% drop in 3 minutes. It is just a matter of calibration.
Edit - added per hour re the 0.6% to clarify.

iOS is lying about battery percentage. If you see 100% it's in 100-95% range.
Anyway, it has more efficient deep sleep.

Yeah. Shouldn't the battery only be at 100 while it's plugged in? Cause as soon as you unplug it, it's obviously using the battery juice...which means it's no longer at 100.

I'm not sure if these Temps and cpu usage are normal, which I don't feel like it's normal, but every time I pick up my phone My phone is just running at 100% cpu usage. Granted I already reset my phone two days ago and got two full charges in. And my battery says it's still learning usage pattern. I'm not sure if this is part of the learning usage pattern phase.

Wait at least 3 full days after setting up a new Android phone before you assess battery life and SOT.
I have exynos S21U and get 8 or 9 hrs SOT with the 90Hz screen refresh rate mod.

Question VoLTE battery drain on GT2?

Hey, I noticed on my new GT2 poor standby time, somewhere I read that it might be caused by VoLTE is this possible?

Try using settings > battery > advanced settings > app quick freeze and select apps that you don't neet to run in background.

I did that but I continue having battery drain, only 3-4h of display time.

Well I have to check this tomorrow but it seems that VoLTE is a problem for me.

might not help you too much
but for me, with VOLTE turned on the SOT is pretty good
like 7+

In my case, with VOLTE off and all apps with quick freeze I have less than 4h of SoT, what I can do?
PD: screen at 120Hz, of course.

i mean its super hard to give any recommendation
it really depends on the apps you are using
if you are gaming with 4h SOT it drains much more than if you are just browsing
take a look at what drains your battery and try to optimize there

I have Wifi on and only use the phone for emails, web, whats and calls. Never playing or heavy tasks.

also if your signal strength is not optimal it burns a lot of battery
if you are having 5g enabled but no 5g contract or 5g in your area, disabling 5g is also saving something because the phone stops to constantly search for 5g

For me - on 4g network, with VoLTE off is better - screen 120 Hz. I also switched off those options to report customer experience.

I have signal off, only wifi and 5g off.

It is much better - for me without volte option ON (I read somewhere in review of different phone that snap 888 dont like volte sometimes maybe it is also firmware related problem ) - 4 h SOT and still 55% battery , mixed network 1/3 wifi + 2/3 4G . With gps off .

Please understand that SOT will never be the same between uses. And should never be compared between users, we all do things differently with our phones. And, also, if anyone mentions his SOT please mention the total usage time, like I have 2days usage, 3h SOT, 30%battery remaining, and this are generally good. You can't have 6h SOT and 2days usage, but you can have 6h sot with 10h total usage and 0% battery remaining! And post screenshots that sustain your affirmations.

Man, yesterday I got 1h 10min of SoT with 9h of phone use at 50% of battery, as I said, I only use the phone for emails, web, whats and one call of 4min, always with WiFi. Its evident I have a battery drain problem, indeed, in idle the consumes batery all the time, my old realme X2 had better battery administration 3 years after I buyed it.
I cheeked all the permisions and syncronitzations and is all ok, maybe the only solution is a hard reset...

My data from last day with VoLTE on my phone needed charger about 7pm without VoLTE about 11pm.

After few days I confirm on firmware A14 - VoLTE eats batter like crazy :/ - how to report that to Realme - their forum don't look good at all :/

Try emailing: [email protected] I've sent them emails about some issues, got some replies but didn't solve anything... Try your luck )
