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.

Just curious on people's battery life experiences so far. This seems to be the main negative I hear about this device from reviews. I am most likely going to get the device nonetheless.
I don't feel like the battery life is that bad on this device.
I can get through a hole day very easily. I play some games (but not that much), I listen to a lot of music and I use Chrome very often.
Still I have about 40% at the end of the day.
For a device with a 1440*2560 5.7 inch screen and a Snapdragon 810 I reckon that it is pretty good.
I can only tell you to get this device it is awesome
Battery life for me is pretty terrible. The battery drain is significant even when the phone is in idle. I usually have access to a charger throughout the course of a day and I feel the need to keep it connected as often as possible. I still love the phone, but the battery life is the worst I have experienced with any phone I have had in the last couple of years, and I have used many. I leave it on balanced mode for the majority of the day and only switch to performance mode when I am going to play a graphic intensive game.

Yikes. Have you tried any software like Greenify to help alleviate the problem or it still persists ?

No, I haven't tried any apps or other battery profiles. Like I said, I keep it plugged in a lot during the day, so I have never felt the need to see how far I could stretch a single charge. This is also the way I have kept all of my previous phones and the Xiaomi drains the battery the fastest in comparison.
Mine lasts me about 12hours. I listen to music most of the day and I'm a heavy user.
Got the phone 2 days ago. got around 4 hours 15 minutes SOT from 7am till 9pm on the international rom. Better than i was expecting. Hopefully I can improve it further.
I have to admit that over time the battery got worse. That would be because I have more apps etc..
What is your SOT time usually?
I noticed today my battery SOT and idle drain has been really bad. The only thing I think I did diffrently was that I logged onto my miui account last night so i could download themes. I have no use for the miui account other htan the themes so I will try logging out and seeing how things are after it....
2-9% per hour is not bad i guess...
If i use it a lot, then only it will go as far as 11% per hour and mostly because the big QHD screen,
When it sleep, it almost didnt drain...
Of course you have to kill/disable all those stupid google play services... Named it Event Log and Checkin handoff etc etc

Are you still using the Mi note pro?
Hey guys, I've seen posts about people getting amazing battery life, both on stock and on a custom rom. I can never seem to get the same results, whatever I do. Sometimes, I'll toggle a setting and I'll see improvements for a day or two, then it goes back. Even more frustrating is there have been times when I turn the setting back to what it was and see improvements. It was like this for a while, but recently I've kinda gotten stuck with ~15 hours from 100% to 10% and nothing seems to change it. I have location on device only (its for weather, battery saving seems to be worse because Google services just syncs all the time and eats battery) and mobile data on. I've disabled pretty much every Verizon app and I just use moto display and the sleep thing. What else can I do to get better battery life short of a custom rom? The only reason I won't do a custom rom is because my parents won't let me spend $25 on sunshine, whether it's their money or mine.

I exactly get the same results as you. I'm on stock and disabled all verizon apps. A help could be really nice.
Keep in mind that battery life varies GREATLY upon usage. I can kill my battery in a matter of a few hours or have it last for nearly a week. Sync frequency, sleep time, connectivity, refresh settings, screen brightness, CPU usage, vibration on/off, number of wake locks...I can go on and on.
For example, I had my S4 last 5 days before it dropped to 80%, as you can imagine I didn't use it much. However, that same phone died in probably 3-4 hours on me also.
What matters most is if you have more battery life than your previous phone. Never compare your battery life to others.

I included some usage statistics in the ingur link. A lot of battery seems to be used by Android os and android system. Is there anything I can do to lower this?

What do you have your screen brightness set to? Your phone looks completely normal in terms of battery usage (Android/Google will always use a couple percentage).
Try turning off adaptive brightness and putting your device to the lowest brightness you can stand, that should add at least another hour or two depending on your current settings. 3 hours of SoT over a days usage with what looks like moderate use (YouTube, Messaging, etc.) isn't too bad for this phone.

Thanks for the advice! I guess I was expecting too much out of this phone Oh well, i'll just wait until i can get $25 in amazon or google play gift cards to pay for sunshine so i can get computerfreak's rom.
I am on CF's latest ROM and I'll say my battery life improved compared to stock, but not by much. I may get 6 hours SoT but my battery is down below 20% by the end of the day, and that is if I avoid playing games. Playing games all bets are off, the battery runs out quick.
There are some out there saying they get 8+ hours SoT and 48+ hours between charges. I call BS on that unless you are running minimum brightness and not doing any syncing or anything location based, and possibly even turning off cell data. Showing off with pictures of their battery stats and not telling the whole story.

If you unlock with Sunshine and install RR, you can use the custom kernel to tweak the CPU and GPU frequency to save battery life.
Additionally, there are other ways to save battery, like adjusting the pixel density and colors. (At least I think so?)
Greenify also helps. I think that is available for non-root as well.
Also, check your wake time. If always awake, could be the Google services running constantly trying to update.
There is an app to fix that, but I think it requires root.

also, my phone really likes to shut off before it reaches 0% battery. Is this normal?

I doubt its normal, buy I have noticed that mine does that too. It usually shuts down around 7% without warning.
Im seriously considering buying this device as it is quite good priced now and it ticks all my needs.
But I dont know what to think of batterlife in day to day usage. Some say its perfectly fine, some say not....
I considered X too, which is good enough on battery for me, with Nougat updated.
How is X Performance after Nougat update?
Any better?
Please share some insights.
Like: percentage used after 1hr videoplay, and after 1hr browsing, and 1hr playing.
Im coming from Z1c with kitkat, which battery performance im quite satisfied ( 6-8hr SoT) and Im affraid to make a wrong choice going for X Performance instead of X, concerning batterylife.
My usage routine is Stamina on, background data off, and no battery drainig social or other apps.
Would like some help in deciding....
This info would be nice to have, as I'm in the same boat as you. I've heard good things about Z5 battery life with Nougat, though...
I get about the same as on my z3

That would be superb.
Is your rooted or not?
And please some more info, your usage pattern, aproximate Screen on Time?
I get a little less usage out of this device per charge than I did from my Z3. With my Z3, I was getting 2 days easily. With the X Performance, I can get anywhere from 1.5 to 2 days depending on whether or not Google Play Services decides to keep my device awake. I use my phone very liberally throughout the day: light browsing, some Reddit, occasional calls (maybe a half hour each day), etc. I found the Nougat update made the battery life a lot better on the X Performance. I don't have any solid stats for screen on time but I think I get anywhere from 2-2.5hrs over the two days.
Thanks a lot. .
So how about your SoT after battery goes below 10%. What does it say under batteryusage, screen, how much hr of usage?
I'm just charging my phone now, so I'll let it run down and I'll report my SoT when it's around 10%
I'm at 22% right now with 1:16 SoT. This was not the greatest run because Google Play Services used up 13% of my battery. Generally, I get around 2:00 SoT over two days and Phone Idle takes up the most battery. If I see my battery draining quicker than I'm used to, I'll reboot my device and that stops Google Play Services from wasting more battery. I'm really hoping this issue will be fixed in a future update. Hope this helps!

Oh man, you are indeed a different pattern user than me.
1:15 hr SOT while your screen says 11%.....deriving from that its good.
But that idle and google play services percentage is bad.
I m using with background data off, just in intervals, and Stamina on, and location info off. I believe it ll get much better endurance in idle that way. But I also leave active the few apps I want, like Viber in battery stamina settings.
Try playing with those settings to get some better idle time.
Thanks a lot.
Just as a follow up: I heavily used my phone last night and I'm at 1:20 SoT (15 hours off the charger) with 70% battery left. Depending on your usage, you'll see much different SoT times
Thanks, that should be 15% used by Screen(should read 50% in stats), and about 15% system, google and idle in those 15hr( altogether 50% in stats).
Well, thats about 6.5hr SOT by batterytests....
Which is not bad at all.
About Same as my Z1c....
Im satisfied with that, although batteryendurance will not be an improvement over my z1c, everything else will....
Thanks alot again, I ll order it....
its about 400€+ VAT now, which is a good price for that device.

Just a surplus note:
My measurments of Z1c being about the same are with background data on.
With background data off I get 70% used by screen on half brightness.
And Much less % used in idle and android system (15%).
Which translates to about 12% battery for 1hr SoT....(surfing).
Gets easily about 8 hr SoT overall.
So X Performance should be about the same also with background data off.
Last barely 12hours to me, not much music and gaming
Just as I measjred, getting 6-7 hr SoT with my usage pattern. Its good.
Wonderful device btw. ?

So did anyone else get terrible batterylife with andeoid 10?
I went from 8h SOT to about 5h.
Am thinking of downgrading cause before it was the best phone ive ever had
There isn't 10 for my csc yet
Anybody else confirming bad battery life on 10?
how where you getting 8hours sot... i was getting 6 and now 5 but i do have a lot more idle cause of the quarantine

Wish I could tell you. All I know is it was the best battery I've seen. Was using it 'normally' and throughout 24 hours I got 7-8 hours battery life always, every single day for half a year. With music streaming for 1-2h, some browsing, location on, bluetooth on, and all apps like facebook, instagram etc. disabled.
Now I get 2 hours 20 mins and its already on 48%. Android 10 was a garbage and I wish I could downgrade without much hassle. I cannot find out what is draining the battery, there is no app. If I account for the apps it has used around 1000mah or less, which is 1/3rd, wihc would put me at around 70% - that would be my old battery life. But there is something else draining 20-30% battery and it is not shown in the battery reports, I am using accubatterry.
I really hate it, now I hate this phone
Battery draining mainly depends on how device is used, means how much CPU/GPU are stressed. Has NOTHING to do with Android OS itself: an OS is a piece of software, nothing else, an OS doesn't consume electric power. It are all the running apps/services - either running in foreground or in background, for example Location Providers & Google Play Services - that drain the battery, as also the activated hardware components like the screen, WiFi, GPS, SIM-cards, BlueTooth, etc.pp. even if device is in standby mode. It are the device's power management settings what control the behavior of Android phones that could affect the system's power consumption, such as adjusting lighting, handling the phone's sleep, and the wake-up, idle, turn-off timing, back lighting or display brightness of the device. It are the device implementers who define the related constants suitable to their devces, it's NOT Google , the developers of Android. With regards to Samsung S10 devices it's worldwide known that it has a very poor power management compared to others.
BTW: Since Android 9, the platform can monitor apps for behavior that negatively affects the battery life of devices.
No matter what you do to your device, it will never stop draining the battery.

You have no idea what you are talking about and should stop wasting everyones time talking about that
So I simply reset my phone and I am back to 8h SOT and happy again.
3h42mins with 62% of the battery at like 8h usage
And after about 15h usage at 51% with 4h10mins SOT ?
I also got terrible battery life after the 10 upgrade.
What do you mean by reset? How?

A simple factory reset, type reset in your settings in the search bar and do a factory reset.
It will delete everything, so make a backup before
I'm coming from an Exynos S10e which was great but had terrible battery, so one of the main draws for me on the Pixel 5 was the increased battery life - I need to get a full day of quite heavy use.
So I got the phone and like it a lot, but although battery life is better (it couldn't really fail to be) I'm not getting the terrific screen on time that others are boasting about. I tend to charge up to 80% or so and try to recharge on around 20% and don't watch a ton of video, so I'm mainly checking emails and news, surfing the web, reading text and sometimes dipping into YouTube.
I've currently used 60% in 20 hours, but that includes eight hours of sleep when the phone was idle and has virtually no sustained screen on time. Overnight, the phone uses about 1% an hour with the screen off, although I do have AOD on during the day. If I watch video (adaptive battery and adaptive brightness on) it ticks down pretty fast.
I'm told that Accubattery isn't really accurate, but it had 'battery health' down as 3880mAh (97%) from the get-go, which worries me. (It also has screen on time pegged at 7 hours and 51 minutes, which I absolutely don't believe.)
My questions are 1) Is there anything I can do to check/improve battery life and 2) How accurate are the Accubattery readings likely to be?
Or am I simply expecting too much, which is entirely possible?
Thank you!
AOD basically cut my time per charge in half, i am not a heavy user so my screen on time is always on the low side. But turning AOD off (and the AOD on move thingy, which apparently triggers all the time when in a pocket or even next to you on a couch) i jumped from ~1.5 days to 3 days per charge (with 3-4 hours SoT light use: podcasts, reading news, etc.).
After the pixel 5 motivated me to go through all those options i set up my old oneplus 3 with the same settings / android 10 and i am getting basically 2 days out of it (again the AOD changes did the trick). Which basically disillusioned me about the Pixel 5 battery, it's nothing special. Just about what you expect from a phone with this battery size and a simple Full HD screen and a SoC that is somewhat energy efficient.
Small Addition:
I'd really be interested in other peoples experience with AOD. I've red people saying things like "you don't need a notification LED when the AOD is so energy efficient" personally i think that is just not true. If you are a power user and you have a daily sot of 5-6 hours maybe. But for people like me that 1% battery drain per hour (i noticed about the same figure when i had AOD on) just adds up to a lot. In two days basically 50% of your battery is gone, if you follow the 80/20 rule, which i do not think is necessary, that basically leaves you with 10% of your battery for other things. Seems like AOD isn't as efficient as some people might want you to believe and a notification LED might something i will look out for on my next phone.
I can't remember what the train without AOD was but it was noticeably less.
AOD is a stand by battery killer. For anyone that uses the phone on a desk facing up. Especially in bright areas where the AOD triggers the max brightness.
However. This affects people who has more than 20-24 hours of standby time. People who do... 8:00 to 24:00 every day (so 16 hours standby) is much less affected by AOD battery drain.
So yeah. For light users. Disable AOD is my main recommendations. I stopped using AOD in the last year that I used the Pixel 2.
All the other tweaks are less relevant. But my rule is to just enable what you need.
Example: every time I say ok Google I'm at home with a google home around. So I disabled ok Google from the phone. (I just tap de assistant icon).
