...4 hours of heavy usage (wifi connection and 3g on but idle)
Mid to periodical usage could reach 24h.
6th day of usage....
i think this is mediocre for me. please report your battery performance to compare.
Any tips to improve this?
I can get around 8-10 hours with heavy usage... constant music, etc.. and about 2-3 days with light-medium usage.

Hmm so i guess there is a problem with my device.
Great!, and how am i supposed to explain this to the service?
I get about 12 to 15 hours of heavy usage via web, text, and email. If i watch video it's less but I am pretty happy with the battery thus far.

I can only get around 7 hours of use.
I have a problem that if i even dont use it, the battery still drain. I got it full charged and theb unplug it. About 8 hours later, it went down to 50%.
Is there any problem with my device?

same here. i don't know how you guys are getting so much better battery life. i can barely last a day and i don't use it all that much. maybe 2-3 hrs of surfing the web over wifi (not even 3g). i even used setcpu to underclock to 200Mhz when screen is off.
Maybe it has something to do with the very first charge.
When i unboxed the battery was fully charged so i drained it and had it charged for 8 hours. maybe it needed to be charged prior first usage.

Is that 12-15 hours with the screen on? Because that's much more than I'm seeing.
I've done a few measurements just to get an idea of the battery life. They are just extrapolations based on a few hours of runtime for each so they are by no means exact, but my impression is that they give a decent view of real values nonetheless. The battery percentage indicator does not seem to be terribly non-linear.
Video playing (SD quality) with full brightness: 5.5 hours
Video playing (SD quality) with lowest brightness: 9.5 hours
Idle at homescreen with full brightness: 6 hours
Idle at homescreen with half brightness: 9 hours
Idle at homescreen with lowest brightness: 12 hours
Music playing in headphones (screen off): 90 hours
Can't believe how lazy reviewers seem to be, I haven't read a single one where they have properly measured battery life for things like playing movies or reading an ebook. It's all just subjective feelings (which are obviously very unreliable).
All in all I am pretty pleased with the battery life (but I've just had it for a few days). I especially like the fact that it's basically a normal Android phone just with a giant screen and battery. This obviously means that standby and music playing times are going to be excellent.
Edit: Those of you who think you're seeing bad battery life, what does the battery use thingy in settings say? Or is that not a good tool?
I read a post somewhere where the OP was getting horrible battery life and found out that the Gallery app was draining the battery.
The OP in that thread said even exiting the app did not kill it, and it kept draining the battery.
Perhaps you can look into this more. I never use the gallery app so maybe why this is why i get decent battery life?
Edit to add:
Here is the thread
http://forum.xda-developers.com/showthread.php?t=826472&highlight=gallery
If it's this post you're referring to it's by me . The Gallery application shows up under battery use though, so I'm pretty sure that's not it.
Are you sure it's really as much as 12-15 hours with the screen always on? If it were 9-10 hours with brightness at half it would around what I'm seeing I guess, but 12-15 is quite a lot more. Not that I'm disappointed, but if better is possible better is what I want

No not 12-15 hours with the screen always on.... I get 12-15 total... Screen on for usage, off for a while, back on to email and SMS ect...
Ah ok, then there's no discrepancy .
I got 10 hours from full to complete off. I was using it to watch streaming movies on 3g
for a couple of hours and then watch a movie off of the sd card and an episode of supernatural.
After that its just web and ebook reading. Its pretty good. Almost the same as my ipad.
I got a total of around 14 hrs plus with wifi and edge on, screen brightness at 20%, around 7 hrs of standby while i was asleep at night, with 4 hrs of heavy surfing, youtube etc. . . No calls though, only some sms and always on IM with nimbuzz logged in.
What i am seeing is with heavy usage i.e. Multiple apps running, wifi and edge on, i get anywhere between 5-7 hrs of battery life which i think is fair enough for a device this size which am constantly fiddling with.

Can someone please post,
Using the supplied mains charger, how long does it take to fully re-charge a drained Galaxy Tab?
As it is a large battery what sort of charging times to expect?
(This is while NOT using the device).

I only get about 5-6 hrs tops under constant usage...browsing,fb,tweeting,watching video...but I buy the phone 2nd hand...I'm going to buy a new battery in the new future..let's see if the battery life over 8 hrs I would be happy : )
EDIT :
Sorry guys,I didn't notice that this is for galaxy tab...forgive me : )

I've not used mine for that long, but the Battery Left app(which I found to be quite accurate on my N1) shows that for MY usage, I'll get about 25hrs.
I've got the auto dim turned off, and brightness at max. I mainly use mine for checking emails, txting, and a few games.
Nothing heavy.
I'd recomend the Battery Left app to you guys looking to find out your battery life. You DO have to "train" it though, which requires a 100%-0% run for you.
Guys,
does.anyone know, do we need to cycle the battery to give it the best performance?
Example, charge up the unit, then drain it completely and recharge it again? Like in the old days.
mine hasnt gone down much. I have it unplugged at 6am and at 4pm i still have about 75-80% batt left.
This is with about approx. 2 hrs of talk and 30mins of data usage and voice calls paired to my BT headset. My screen brightness is set to 40%

I once got up to 20 hours of moderate usage. But with heavy usage I get about 12 hours or more. I lose about 7% when watching an episode using flash....kinda sucks but I watch a lot of anime online. But I use this as my main phone too. Its replaced my nexus completely. though it was nice with my nexus cuz I could swap batteries. This is how I condition my battery. I let it get to about 2-5% then I recharge it. I don't let it get to zero cuz I heard you can damage the cell. sometimes I charge it to about 20% then I unplug it and drain it to 5% then back up to full. I just kinda switch it up. At first I was getting horrible battery life but ever since I started conditioning it this way I get great results.

Hi all
Here in UK We still waiting for TAB 10.1
very confused between ipad2 or this one
after a lot of reading I've made my decision to buy this one, but the only thing I really want to know is the battery life for this one as it is very important for me
( doing a lot of travelling long distances on the plane)
Engadget said that its battery lasted above 8 Hours of video loop while others said it lasted just above 5 hours.
I know that the Tab cannot beat the Ipad2 when it comes to Battery, but I am still buying the tab10.1 if its battery lasts 1 or 2 hours less than the apple product.
Could you please -who own this item- let me know how the battery life is?
Many Thanks
i just received mine the other day. i let it charge overnight.
i then used it for just about 9.5 to 10 hours and plugged it in when the
battery meter was at 15%.
the battery life is excellent !
it really depends what you are doing on it. I use it throughout the day but primarily while at work to keep my sanity (I work overnights). I watch loads of HD youtube videos and the browser since my office thought it was cool to put website blocks and disable flash (for youtube blocking) so to see videos on sites or actually see full sites the tablet is crucial. I tether the wifi from my HTC Thunderbolt for access. I do also play some games. I can get through my 8 hour day with about 50%
Edit
based on pandamaja's response below, I didnt actually touch the screen brightness so that means it is working harder to auto adjust itself according to the brightness it is in
Battery life so far has been excellent. I don't travel as much as I used to, but I can see this thing lasting for a good while. Like others have mentioned, it depends on usage.
The display is going to be the single largest battery drain. I'm not sure about the 'others' tests, but the tests done by engadget and apple are done with the display brightness set at 50% I believe.
I've been very impressed with the battery life so far. My Evo basically lives next to a charger. Before I went to bed last night I considered not even charging the tab.
So far so good for me. I haven't timed it but I have been using the tab on and off for a couple for days before needing to charge it.
I do keep the brightness level pretty low.
I have had my tablet on since I bought the device. I charged it for an hour after playing with it, and have watched 3 hours of TV shows, and when I have not been using it, it has been idling (for 4-5 days). The battery was at 37% when I finally plugged it in last night. This tablet's battery life is the best battery life of any device I've ever owned.
pretty much been having the same experience as everyone here. i've gone through 2 days without charging (currently at 47%), and this is with browsing the internet, watching videos, and playing games. depends on the display brightness and usage. i have mine set at about 50%, as i find that plenty sufficient.. this panel gets bright. the tab also holds charge real well when in standby.
Thanks for that, very helpful
any one has set it on video loop with reasonable brightness (50% i guess good)?
How long can u get?
the reason I am asking because I am flying quite regularly to mexico ( 10 hours) and mostly watching movies
any help very much appreciated
Many Thanks
how did samsung even manage to squeeze that amount of juice in?

Hey OP
I believe that most reviews for the tab says it can play ~10 hours of video using 65-70% brightness. I've read at least 5 reviews having similarly result. Only one review got 5 hours of video. I would doubt that review.
FYI, the ipad2 gets 10.5 hours under 70% brightness playing video.
I got my tab yesterday. I played video for about 2-3 hours, using 70% brightness, and baterry went down ~30%. I would say a 10 hour video playback seems to be correct.
I got a refurb Note 10.1 2014 from Groupon about a month ago. The battery life has been poor but I didn't use it enough to quantify it. I got home form work today and it was at 65%. After exactly an hour of use, it told me it was about to die at 5%. I can literally watch the battery percentage tick down while writing an email or browsing the web. Is this normal? I've had 11 android phones but this is my first tablet, I've never seen performance this poor.
This is my issue with android devices. If you are not an above average user and know how to trouble shoot to find what app or apps is causing your battery drain you will be left thinking the device itself is not good, when it's probably a wakelock or some background app killing your battery.
My device has good battery life. I wish it would do better with simple Internet browsing, but watching videos and other tasks are great in my opinion.
My advice, try to find if your issue is software related. After ruling that out, the only option is that out must be hardware related.

I found the battery poor for the first couple of weeks. I gave it a full charge, took it off a couple of mins after 100% each time, only letting it drain down to about 15%. I was getting about 6 hours on screen time without power hungry games.
Then a few days ago drained it full, and charged it over night, now getting 9-10hours on screen time - mainly web surfing, watching full hd film streamed off home servers and low power games (5's.....far too addictive and simple). This also includes some use streaming bluetooth to wireless speaker with screen off, so at least another hour use on top of the 10 but with the screen off.
I'm about like redsurf. 6-10 hours of screen-on depending what you are doing with it. If you are only getting 2-3 hours there is something wrong. You can check under power in the tools/settings menu to see what is eating your power. If it is a program, kill the task. If it is the screen (more than 50% any time I have checked) and you are only getting 2-3 hours, definitely something wrong.
Oh, also try turning down brightness.

Funny enough, I probably have my screen brightness set to between 10% and 25% and rarely ever need it to be turned up any higher than that.
By rooting and disabling alot of bloat stuff I get an additional 1-2 hours out of my note 10.1. Just saying
I'm sure there could be a software issue, but even if i was gaming at full brightness with 40 background apps (I don't), 2 hours is unacceptable and probably defective.
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 Samsung Galaxy Z Fold 2 before depleting the battery.
Then, drop a comment if you have anything to add!
I charged to full after receiving the phone yesterday. Took it off the charger around 6:45p. It's now 1:15p the next day and I'm at 9% battery remaining. I had mixed use between social media, YouTube, Spotify and some light gaming with using the big screen 85% of the time. Screen brightness and display settings are all default.
Managed 7 hours SOT which should improve after a few days.

Yesterday, I got six and a half hours SOT with and hour and a half of phone calls. If the battery life continues, I'll be happy. Had the adaptive brightness on and the adaptive screen refresh rate on. Only social media was WhatsApp and Discord.
also am part of the 6-7h screen on time gang. not intensive usage though.
This is a SOLID TIME FOR ME JUST OVER 8 HOURS on screen and as you can see i was playing a game for a hot minute.
5.5 hours 4g full day. main usage on inner screen ..
its actually pretty bad for a 4500mah phone. it need to be constantly charged ..
Some of the posters posting images from the stock battery usage chart fail to mention that those screen on times also include duration of when the device was plugged in charger.
not the best, somewhere around 6 hours sooo
Max brightness and aod im at like 4-5 hours SOT.

Its actually not 8hrs. Use an app called accubattery for a charge to charge battery backup time. The standard builtin battery monitor in samsung phones are measuring battery life from 12 to 12 midnight. So as your screen shot clearly shows, you charged the phone around 3am, so 12-3am screen on time plus 3 till full charge if the screen was on, all these count towards the screen on time as per samsung. Which obviously doesn't show the actual screen on time per charge.
Did u guys measure the sot when your z fold 2 have finish measuring the usage pattern and shows how long battery life left or before? so far still learning usage pattern getting around 7 hours of sot with both inner and outside screen usage. pretty solid especially with 120hz display
Fold 2 owner for 1 week now. I am averaging between 4-5.5 hours of SOT and this is over 24h (average) on one charge.
My device is currently set up with adaptive refresh, adaptive brightness, radio is set to 5G Auto (so I'm bouncing around 5G, LTE+ & LTE) and mixed unfolded/folded but mostly unfolded (30/70).
I'm quite impressed considering my N20U gets 3.5 to 5h of SOT at QHD/60HZ, same 5G settings.
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 Samsung Galaxy M51 before depleting the battery.

SS or it didn't happen
I've had this phone 2 days and so far I've had 6 hours 31 minutes of screen time and I have 58 percent battery left. This is mostly YouTube, Web browsing, an hour of downloading apps from play store and a bit of emulation (ppsspp) am extremely impressed with the battery life on this phone.
Battery lasts more than 2 days at Medium Power Saving mode with moderate apps usage(no gaming but with youtube, magic fluid live wallpaper, whatsapp, browsing) and SOT approx 13+ hours in these two days. At the end of second day battery remains at 30-35%.

Exactly how do you think a cheap SD 665 11nm chip with a 5,000mAh battery will do against a higher tier SD 730g 8nm chip with a 7,000mAh battery?
Hmmmmm ?

To come back on it, I have it since today and so far it's looking like the G8 Power has better or equal batterylife, standby drain is somehow bad on the M51, I checked all apps. Still I'll let the software settle and get through more cycles and check Gsam Battery Monitor in a couple of days again.
I honestly blame Samsung's other apps that aren't used and aren't able to be disabled or uninstalled.
Hi guys. I wanted to let you know my findings and provide some test results of galaxy m51 battery life. Firstly, I will outline what was my priority for that test. I wanted to check how long the phone can last mainly on google maps navigation with additional apps in the background. Also this test is a bit static so to speak but had no chance travelling for so many hours. That said I believe SOT was tested correctly for my planned usage. I guess in a real case scenario, I would need to do some more browsing and perhaps occasional screen switch offs during a break like filling up the fuel or stop to rest on a bicycle.
How I performed my test.
1. I did some initial installations, downloaded my apps and logged in to social apps such as FB, Spotify so they can work in the background, send notifications etc.
2. Once I completed the setup, I charged the very new phone to 100%. AccuBatter reported capacity was 6800mAh designed capacity not 7000mAh and estimated capacity 6700mAh.
3. CPU-Z reported Snapdragon 730 so I regret it is not 730G and honestly I do not know how to check with online stores as the packaging does not help with this. Also, I plan to test POCO F2 PRO 8gb ram/256gb version the same way and see how it goes since I get better hardware, but I like SD card slot on galaxy m51. Very useful when resetting the phone.
4. Set google maps navigation, lunched another app which uses GPS and LTE for maps showing speed cameras, road works or dangers which I use alongside with google maps. I also start shuffle play on Spotify to imitate streaming the music in my car or on the bike.
5. WiFi, LTE, GPS, Bluetooth, sync was enabled, blue light filter enabled.
6. Between 15-20 apps were in the background.
7. I unplugged the device from the mains.
8. Initial 15% discharge was with a WiFi connection with my router. Then switched of my router for overnight, left wifi enabled on Samsung but it had to continue downloading data over LTE such as Spotify music streaming. I also changed google map setting to day light only to avoid night backlight.
9. I went to bed? and in the morning there was still a lot of juice.
10. Around 20% discharge I took about 100 pictures most of them in burst mode to simulate a trip where you simply stop and take some snaps.
11. I stopped the test at 1% discharge and noticed no heating problem. The phone was cool during the test.
The overall SOT measured until 1% discharge was a staggering 17h 50m? Below you will find AccuBattery screenshots. At remaining 15% I had still over 2 h 42 m of use left.
This phone reminded me of good, old days of my Samsung galaxy s3 with a Zerolemon 7000mAh?
Now with my galaxy s7 deteriorating battery (current capacity just over 2300mAh) this is a great thing. For Galaxy s7 I also own a KiwiBird powerbank case of 5400mAh right from the beginning wich did its job when away from the mains, travelling etc.
I guess for a more accurate SOT, I would need to add some phone calls and browsing but even with I deduct 2h, it is still nearly 16 h of use. Like for me excellent. I also do not plan gaming.
On the downside of this phone it seems like my galaxy s7 takes a bit better picture, but it just might be my perception of selfies taken. Back camera is also just ok on a cloudy day. Ok but that is an offtopic.
I got my M51 yesterday and I am not fully sure yet about battery lifetime. I have charged it to 100% and about 8 hours and 2.5 hours secreen time later I am at about 90%.
Coming from my Moto Z Play I am not sure yet if I stay with the galaxy. The Mot Z Play with Incipio OffGrid Wireless Power Pack mod is about the same size and weight. Though provides less capacity (3300mAh phone + 2200mAh power mod) but battery lifetime still was bout 3-4 days usually.
The M51 is also getting considerably warmer during use.
I noticed also the Samsung battery saver with medium settings can reduce the CPU clock to max out at 70% which is handy. Not sure if there is any undervolting, underclocking tools as I think I would be perfectly fine with less performance - actually I was able to reach insane battery life on my old Galaxy P1000 with TricksterMod and custom undervolting back in the days.
I still believe better lifetime with the M51 would be possible bz reducing CPU clock and also with better screen brightness control. I noticed many times already that the M51 screen was too bright for me and having to reduce the slider to "minimum" position or very close to it. Also I noticed that the screen brightness slider is not linear at all. So on the last notch on the left side the screen really starts to dim properly while to the right there isn't much change. Also I like still to use automatic screen brightness adjustments but found the automatic adjustment often moves the brightness too high.
Also a possibility to limit the used screen area (e.g. display black bar on bottom/top) would save energy on the AMOLED screen while still providing more than enough screen space.
EDIT: One-Handed mode sort of provides this feature, but not exactly what I was looking for (like cinema-bars on top and bottom and no prominent "one-handed-mode" title.
I will continue to use the M51 for a couple of charges and decide if I am going to trade it again. The phone itself is performing well, supporting VoLTE WiFi calling but seems to lack carrier aggregation for no apparent reason. I strongly dislike the slippery, fingerprint-attracting, cheap-looking plastic backside of it.
I also hate that everywhere you tap it tries to sign up to a Samsung account. Also replaced the launcher with Nova launcher.
Below is the answer to almost all above useless posts
Battery life tests - GSMArena.com
Why I say useless ?
Simply. SOT will be completely different when you read ebooks compared when you watch movies or browse Internet.
Gsmarena does standarised comparison
I am fan of long life battery phones. I used "king" Lenovo P2 for over 2 years. M51 is better.
I'm at the fourth cycle of charge.. and got 15 hrs so far.. have done a heavy idb debloating
maby it will increase over more charging cycles?
i m getting about 20h sot normal usage
facebook lite, browser , youtube , aliexpress and playing alphalt extreme 30 min
wifi and dark mode on
brightness between 10-40 %
data off
location off
this phone have a very good battery
