Hello everyone.
I currently own a Tab s 8.4 LTE version for exactly 40 days only. I began noticing battery being so weird last week so I will be direct and to the point as much as I can.
A week ago, I noticed that my battery isn't doing so well, I am just a med (sometimes heavy) tablet user ( I mainly chat, browse facebook, read articles, play some youtube videos and I play music as well) I had my battery charged to 100% before a car trip that lasted for around 4 hours, by the time I arrived to the destination, the battery was on 10% only.
Here is what I did on that trip:
1- Had Mobile network connected all the way (used it for chatting on whatsapp, facebook and reading some emails)
2- Listened to music for 45 mins.
3- Played 30 minutes of clash of clans.
When I arrived to my destination, I waited the tablet till it completely drain then I put it in charger ( I was astonished by the fact that when I instantly put the charger in, it read like 30% instead of 0 or 1%)
Anyway I charged it to 100% and went to test it by watching continuous non-stop 204 minutes of movie (Thats 3 hours 20 minutes) and I was happy that it only dropped from 100% to 67% with 50 percent brightness and (Wifi/Sync connected) then I played clash of clans, 15 mins of clash of clans dropped the battery from 67 to 53 so I was pretty much shocked (like 1 percent for every in-game minute!)
The third day I left it in standby mode to test if it drains unsually when it is idle, I left it for continuous 12 hours on 100% (Airplane mode on, no wifi, no sync) and it only dropped 3% in those 12 hours. I managed to acheive a 4h on screen and 1d 4h battery on time (Which made me pretty sure that the battery is not defective, may be just the reading is faulty)
I tested it today. Charged from ground zero up to 100% then I used it. My activity mainly was:
1- a lot of chatting (like 2 hours but not continuous) on whatsapp.
2- 45 mins of music and 15 mins on soundcloud.
3- 40 mins of Clash of Clans (drained my battery in a significant way)
4- Checking facebook notifications, gmail and browsing some websites on hourly timed intervals.
I managed only to get 5h screen on time and a total of 7h of battery on time. Screenshots in attachments.
More importantly, I used it from 100% till it drained to zero then I put it on charger, it automatically read 15%! (Happened to me before that it read 30% instead of zero or 1% then I drained it from 15% to zero again, put the charger and it read from zero%)
Please help me get answers for these 2 questions:
1- Do you think this battery is defective? I own this LTE tablet for only 1 month. Or do you think it only performs poor?
2- Does a game like Clash of Clans really drain it that fast? Like 1 percent charge for every minute or minute and half?
3- How long should it normally take to charge from zero up to 100%? Mine takes exactly 3 hours or 3 hours and less than 10 minutes. Is that okay? Or should it be longer?
Thank you
Can you go back this this thread and try what I said. http://forum.xda-developers.com/showthread.php?t=2809818. I dont want to copy and paste it again lol.

Hi all,
I know this issue has been kicked to death but I'd like to get some opinions. I've searched and read through numerous threads about the tp2's battery and some are extremely happy with their battery life while others are not.
Just today I was talking on my tp2 for 5 mins and the battery went from 98-99% to 91%. This was around hr after I had unplugged it from a 7hr recharge (went from 50% to 100%). This would mean I have a talk time of 50-60 minutes, which doesnt seem right.
Typically, I get down to 40-50% in a day after heavy data usage (google maps, internet browsing) with no phone usage.
I've installed maybe 10 tweak cabs/programs and I've made sure s2u2's display mode is set to rawbuffer.
Thoughts?
Is your battery/device new? The battery needs a couple recharge cycles to reach optimal capacity...
have had it for 4 weeks now. Are we talking about 0 to 100% when you talk about recharge cycles?
I wouldn't worry too much. I find that when the battery capacity is above 90%, the readings are not very accurate. I've sometimes experienced a drop of 6 or 7 percent over a span of a few minutes and sometimes, it's stuck on 99 or 98 percent for an hour of usage.
I use my device heavily during the day and it gets down to about 40% at the end. So, that's pretty much in line with what you experience.
My phone has been unplugged for 8h 30mins. The battery has been used for: 40mins of phone calls, 25mins of that with bluetooth, about 25 texts, the screen has been on for 1h 45mins, it has been running for 2h 6mins, the internet has been used for probably 3/4 of the screen on time, and I have been using wifi for probably half of the time that it has been unplugged. I am using the stock battery and right now my battery is at 37%. Would you consider this good battery life? Thanks

Yesterday I had wiped my battery stats after I bump charged my phone to full because I just switched to New Guy rom. My up time made it to 27 hours with awake time at 4 hours and 10 minutes. The first two and a half hours was mostly texting, a few short phone calls and some light gaming and browsing around the phone to get everything set up the way I like. The last two hours consisted of over an hour on the internet, updating 25 apps, lots of texting with 2 short phone calls, 40 minutes of listening to music and about 15 minutes of gaming. I still had 12% battery left after all of that. I was very surprised. so what you have listed sounds like your battery life is fine.
hello !
i was just wondering if you're experiencing the same battery drain I do.. I am on battery since 7 o clock when i went to school and I am left with 14% of battery now after 14 hours.. facebook updating every 4 hours, push notifications enabled, 3G on, 40 minutes active on facebook, 10 minutes of browsing and a bit of gaming ~ 2h7 of screen on time and 30 mins of phonecalls..
is that normal?! post your results or stats please !
That sounds about right. I usually have to charge at the end of the day around 6pm.
whats your usage?
and hows it about the screen brightness? mine is approx. ~30% so autobrightness if i get into light..
On a normal day for me... I'm txt constantly and browsing and or doing something on it.
My phone is off the charger 6am onward. By the time I get to 4pm... it's very well at about 10% left.
Screen brightness is usually at 25%. I've also recently removed most of the bloatware off the phone which doesn't run.
My autoupdate is mostly turnoff off on all my apps except for fb every 4hours, twitter every 4hrs and my email is on all the time.
Avast is always running and I toggle between data and wifi constantly.
I'm happy if I get a good 12 to 14hours worth of usage before a charge. Mind you I'm only running on a 1350mah battery. I was thinking of looking for a 1800mah. Could give me a few more hours.
Cheers.
why 1350 mah? normally the arc comes with 1500? okay.. that sounds fine.. screen on time bout 2 hours right?
is this normal if you are playing with your phone alot, im always picking it up to do something or another but my drain is about 1% a minute
are you guys getting this as well
edit
turning fastboot off seems to be increasing this to 1% every 2 mins, anyone else noticed this
dial *#*#3424#*#* (charge battery first 100%)
to do battery test (through more test then battery test then run)
good battery is 88% remaining after 1 hour test, airplane mode, 100% brightness
edit:
doing a battery test now, so far its 95% remaining at 100% brightness and been running for 25 minutes, apparently 88% remaining is good!
edit
running for 37 mins and now at 92%
edit2
running for 60 minutes and usage was 88% at 100% brightness
Haven't noticed anything that extreme yet. But on the other hand I do not play 3D games that are really taxing the system. I just finished a 30min session of playing Secret Of Monkey Island in ScummVM + made two short calls and lost <10% of battery charge.
I have the screen set on auto brightness. Running totally stock and this is only the second charge. Not too bad I guess.
I am having the same issue too! Because of this, my battery drops to 50% usually after about 3 to 4 hours.
My best guess is that the battery is not fully calibrated.

hi, I would like to buy Fold 4 but my fear is the screen hours are a bit short on average, how long does it last for you? and if there are more in-depth tips to extend the battery!
I get more than 20 hours of heavy work , with about 4.5 hours of screen on, This is my daily 'office' with three email accounts pushing real time emails , Wifi or 5G UC conncetivity at all times, big screen used about an hour of the the 4.5 to review and sign documents and use CRM tools that reqiure a bigger screen , when I do not have the laptop out of the bag, especially when traveling. No gaming, music, etc. but on the other hand I never use the 'power saving' mode. Here is a snapshot of my phone after it left the charger almost 9 hours ago, 3.5 hours screen on, 5.5 hours off but apps run in the background and 65% still avilable. I am on the phone on calls often, text, email, and use the big screen constantly, and never saw below 25% battery at the end of my day , 12-13 hours after my day starts. Of course , if all you want it to be playing games with 100% CPU utilization , big screen on , QHD 120 Hz refresh rate at all times, speakers on at 150% your experience might be different. This phone, IMHO, is more business like and does the job.

same here, with normal use I usually get 4,5 hours of screen on time with 8 hours or so of the screen off time. I think z fold 4 normal use will have 4 hours screen on time
I get 7 or 8 hours of SOT when using WiFi at home. Out & about on 5G I usually get around 6 hours of SOT.
I mainly browse the web, take calls and use WhatsApp. This is per 24 hrs inbetween charges. My phone goes into Airplane mode (with WiFi off) at bedtime.
