S8+ Battery question - Samsung Galaxy S8+ Questions & Answers

Have an S8+ bought a couple of years ago from a friend as an ex contract EE as he had been upgraded to an S10. Factory reset with sim unlock to allow EE PAYG SIM
Running stock non rooted 7.1.1 with no issues apart from due to reading these forums I'm now paranoid about my battery.
For about 90% of my day it sits plugged into a charger acting as a wireless hotspot for other devices, when I am out and about it seems to hold charge well but if I am using video calling or running with GPS on i can lose about 20% an hour.
It's currently at 82.01% and 701 cycles using the SAM info tool.
Apart from that it's fine. No bulging, no software issues. Do I need to be concerned?

Edited, not 7.1.1, I meant Android 9 one UI. My tablet is 7.1.1

I think that is normal behavior. Every phone battery will lose its maximum capacity overtime. 3 years+ battery might need to be replaced if you have concerns. I have the S8+ as well with over 1000 charge cycles.. with moderate usage I can still reach 4.5 hours screen on time. Video calls and GPS navigation with screen ON will drain battery.

[Q] i9020a AT&T/Best Buy Version Advice

Hello All,
Hoping to get some advice. I bought the official i9020a from best buy yesterday (on launch day) seems to be a great phone but I have a few questions and problems.
I unlocked the bootloader but did not root it yet
The biggest issue is battery life. Its terrible (like nexus one before applying the wifi setting trick after 2.3.4 terrible). this NS loses almost 10% of its battery power per hour on standby.
While on standby I have the following running
-wifi turned on
-3 push gmail accounts
Also I noticed that the hotspot doesn't work. when i turn it on it briefly shows 3G and the signal strength bars in green but then the 3G icon goes away and the signal bars turn white, my tablet and laptop can connect but no internet from connected devices and the phone browser itself - just page's not found
my baseband is: i9020aucke1
kernel version: 2.6.35.7-ge382d80
adroid-build 'at' apa28 #1
Build Number: GTJ61
Any advice on the above would be great, I can easily return it but would rather keep it.
Anyone else buy the official Best Buy version and having issues?
Also Anyone know if this phone is locked to AT&T? I don't have handy access to a t-mobile sim card.
Thanks in advance!
Flash new rom. I am sure ATT has some tethering lock on the build. That should be expected.

10% / hr is unbelievably bad (assuming the display isn't constantly on). What's consuming the battery in the battery stats?
Thus far no subsidized Nexus device has ever been sold sim locked (The Vodafone Nexus One, T-Mobile N1 and NS and the various Canadian Nexus devices). I'd be surprised if it were sim locked.
Thanks everyone for the tips. After my original post and now I finished the root and installed cm7.
Cm7 took care of the hotspot issue. Battery life is still pretty dismal in standby. Ill do a test tonight and leave it unplugged all night and post what used the battery the most in the morning.
Thanks again

no man, something is really wrong with your device. My phone loses ~1% in each 4hrs in stand-by (during the night).... I can easily stay 2 days with one single charge (with light use) and with everything ON!
edit: oh, and btw, you won't find better battery in any rom out there. stock rom with stock kernel is the best so far (regarding battery life)... i really tried every single combo and it's the main reason i'm back to stock after so many time (with several devices) using cyanogen. with cm7 i use to lose 1~2% per hour in stand-by!
edit2: you should make some complete battery cycles. Battery life in the first week is not really great, but not that bad anyway!
I think there is something pretty wrong with it
a little over 4 hours last night unplugged in standby/locked
start power: 75%
end power: 35%
most used
display 64%
android system 6%
cell standby 6%
Everything else was system stuff at 1%
Display seems to be the culprit in standby.
Hardware? If so I can easily exchange the phone
Thanks again for the advice
I bought the T-Mobile version back in April. I found that my battery life on day 10 was about TWICE what it was on days 1, 2, 3.... I guess the battery adjusted as it got used some.
I suggest you give it two weeks and then note your battery life again.

I have seen the "battery gets better over time" statements quite a bit on XDA and other forums. I'll give it a week or two and some cycles.
I have to say the "it gets better" is not something i have ever encountered on any smartphone or dumb phone i have ever had though?
Anyone also getting really really slow charging during the 1st week?

If you previously had a non samsung device it charges *slow* even on a 1A charger. No way around that.

thank you! yes - i should have probably mentioned that this is my 1st samsung smartphone.
Yes, it charges really slow and it wont be better. Takes about 3,5hrs to a complete charge.
Battery really gets better after 2 weeks, but even in day 1, never was so bad as you described.

Fixed!
Ended up returning to best buy swapping the phone. the new unit straight away showed normal discharge during stand by and normal battery when in use.
In the end a bad phone.
Thanks to all for the above responses!
ya you definitely had a bad dud...i was lucky in enough to get a good "dud". with approx. of 3 hours of display on, background syncing, and other moderately intensive tasks i was at a point where i was going on 1 day 12 hours 16 mins and still had 40% of battery left.

[Q] defective device or battery

friends and gurus
i need your help in deciding if something is wrong with my sensation 4g or is it something else i am doing. the main issue is that battery life sucks. the first sensation i got also had the similar issue, and i exchanged it for the new one. but i have the same issue. i have went thru at least four cycle of draining the battery and then charging it up. also did the battery calibration. i haven't rooted the phone. just using go launcher ex instead of sense in hope of getting more battery life. so, now my question is is it just my bad luck with sensation? should i try one more time in exchanging device with t-mobile or should i go with HTC service?
will appreciate any help.
this is a detailed log of today's observation.

12:37 pm 25% -- no use
01:17 PM 15% -- placed a two min call.
02:00 PM 14% -- at 15% phone went into power saver mode and it turned off wifi as well as mobile data.
02:40 PM 5% -- now can't wait, plugged into charger :-(

It is easily one of the two... Try factory reseting the phone if that has no effect, id just return for a replacement
You could also s-off your phone and look into some of the roms in your region, could also be helpful :|
http://forum.xda-developers.com/forumdisplay.php?f=1112
With my phone personally...if i charge phone to full at 5am..its full at 7am
(Currently using Stock Rom/Kernel used ADB to pause applications runs like a champ!)
Best of luck with your issue
thanks for your reply. but why it need factory reset? i got phone just a week ago. i have installed few apps like unblock me game, juice defender, battery calibration, volume control+
(underpower speaker is another issue). , google maps, go weahter, go laucher.
the phone i have is made in china and manufacturing date is 7/2011.
s-off phone will void warranty, so i will wait till warranty period is over.

snap!
seems to me that your getting pretty much the same use from your battery that i am. i had the htc desire prior to the sensation and to be honest the battery life is comparable. i was expecting the sensation to be better battery wise but but i guess duel core is desire on speed so will use more power sucks though, i just plug phone into charger every night. don't think changing the phone is gona help.....battery life on htc is just bad. maybe buy a backup/second battery.
i will be more than happy if i have to charge phone just once a day. it drains out by 3:00 pm, then it is a real issue. That too without any long calls. i am sure, if i talk for one hour, then battery will die on spot.
the usage of today is in fact much less than some busy day. i am inside my office so have used landline/ skype for calls. if i have to be outside my office, then it gonna be a problem.
on a side note, what good alternative to sensation is there with T-mobile USA? i have seen some amazing battery life with iphone 4g and motoroal defy. and my own blackberry could go on for two days without a need to charge.

I too have been very frustrated with battery drainage. But for me, it didn't get bad until after I flashed modified ROMs. And I am not ignorant to flashing ROMs and I have done everything I can to find out the battery problem (battery calibration, bump charging, proper RIL files etc). But I can not get more than 8 hours in a day for any ROM. And these ROMs proclaim to be better on battery usage.
When I was on stock, I was getting 24 hours with moderate usage.
The thing I do not understand is that some people brag about their good battery usage and others with the same ROM are getting bad drainage. There are so many variables to battery drainage that trying to understand the problem proves difficult.
So I am just as dumbfounded as you.

How often does the mail client poll for new mail?
Do you leave your wifi on all the time? And if you do is it always connected, or just on and sometimes connected? When its on but not connected it will scan for available connections very frequently causing drain.
How is the is the mobile service in the places where you spend most of your time? If you spend a lot of time in places where the reception is poor then anytime you have no service the phone will search for service causing drain.

I am next to router all the time . As for mobile signal I usually get 3 to 4 bars. Email client is push gmail client as my company is using Google business app. Even if I dnt use the phone, it drains about 5% battery. If I use moderatly then all bets are off.
Since I have a similar battery problem and have done hours and hours of research including testing various ROMs, I think the answer to this strange behaviour (some people with good battery life, some without) is indicated by TechRadar's Sensation review:
UPDATE: We've finally managed to get our hands on a new review model of the HTC Sensation, and the good news is the battery life is definitely improved.
It seems that a combination of data-hungry applications and a slightly dodgy model caused the odd readings from before, although we're not entirely convinced the above scenario isn't one power users will face, which is why we've left it in.
But in normal use, and by that we mean sending 42 texts, spending 49 mins on the phone, watching an hour and bit of video and using the music player constantly, plus a few minutes spent using GPS to track ourselves and browsing the internet for roughly 45 mins, the battery pretty much lasted the day, although it was often in the yellow zone come 11PM.
However, what was more impressive (and a relief) was the sleep state of the HTC Sensation. Where before the phone would get very hot and start spewing out battery life in our pocket for no reason, if you leave the phone locked up for around 10-15 minutes on our new model the power consumption dropped to almost nothing.

I was going to switch to get a replacement model today since I'm still within my "grace" period, but something strange happened yesterday.
After trying out loads of different custom ROMs which all made no improvement to my terrible battery life, on Saturday I went back to the stock ROM (although the 2.3.4 version which is not yet out in Ireland), and on Saturday I suddenly had decent battery life (i.e. lasted the whole day and more)! Saturday night, still planning to return my phone on Monday (today) I switched back to the 2.3.4 stock ROM and put S-ON back on for warranty purposes. Then Sunday and today I still have the acceptable battery life of 1 or more days with light usage!
So, still have to do more research.
But simple answer:
Just get a replacement and hope you get a "working" model; otherwise, ask for a SGSII.
well, this is my second one. and i also have the same observation, after upgrade to 2.3.4 , battery life seems to have improved (OR is it just a perception? ). I have got much talked about anker battery, and just put it in. let it go thru couple of charge-discharge cycle, and then i will comment.

i have been using anker battery for last few days. looks good so far, it lasts a day. It works great with wifi, but using data on 4g (TMOUS) drains it a lot faster.

Battery Drain Fix

Noticing your Galaxy S6 battery is draining too fast? This thread can help.
Part of the problem lies within a memory leak which is a known problem that Samsung is aware of and is reportedly patching in an upcoming update.
The other issue is Samsung attempts to load everything into memory and run several services in the background as well as hard loading the phone with bloatware.
Here is how I gained 30% better battery performance. Guaranteed
*Prerequisites
*Need to be rooted for every tip to work.
1. Disable anything you consider bloatware
2. Go to settings then application manager and disable both ANT radio service apps. You don't need this. Causes massive battery drain. Google it if you don't believe me.
3. Go to the app store and download "Servicely" from Franco. Paid app but worth the money...trust me. (Need root)
4. Once in servicely add running services and apps to your hit list, choose start at boot and run hit list while screen is off.
5. Reboot your phone. Give your phone a full charge and see the difference
Attached is a screenshot of realistic usage. I was on a poor lte signal for 9 hours and conducted several calls and used my phone moderately heavy. As you can see i got through my entire work day and still have 6 hours left at moderately heavy use.
Remember, this is realistic. I could have shown you a screenshot showing 18 hours left after only using it 1 hour. What I'm showing is a legit 9 hours of usage. Before I made these tweaks I would be at 10% battery or less after nine hours of the same usage.
Post your screenshots after 24-48 hours and let's see how much you are saving.

Do you have a VZW Galaxy S6?? or are you using a TMobile one?
Without doing most of what you have on the list:
Didn't load Servicely
Did not turning off ANT which is a low power service used by heart monitors and other physical monitors
Did already disabled the apps I don't use and
did the deal with the google services/play but not much other than that.
I don't play games on my phone, but I do use it for business, calls, lots of messaging and keep WiFi on most of the time except when I am between locations when I turn it off. I only use BT when driving and keep it off normally.
All of which can be done without root, though I have rooted my phone.
YMMV but a lot has to do with what apps you do use, what you actually turn off etc...

Yes I have VZW. Use your phone for a few days and you will start to see battery drain due to the memory leak primarily and your load of apps

I've had my phone for 10 days now. Rooted the first day, loaded my apps and configured that day and sunday so it was work ready on Monday. Ported my number over Monday morning. Pretty much the same for the past 7 days now since then.

Its kind of like who cares?
There are 24 hours in a day and I sleep at least 7 hours of that. The screen shot shows it is 6 in the evening, the phone has been on for just under 11 hours and it still 53% full with an estimated 12 hours left. Even if I am up for say another 5 hours or so, I will still have another 4-5 hours worth of power easily and since I sleep with my phone on a charger every night I won't run out.
On top of that I have AC powered chargers all over the place, in my home office, by my recliner in the living room, in my office at work and even in my truck where I have a two port USB charger with 2A each which is better than some AC chargers. That is in case I really start using battery power for some reason and need to recharge sooner than once a day. All of which was purchased when I had my Note 3.
The costs to get into this phone has been one of the lowest of any phone I have ever purchased since it uses the same chargers, same apps etc. The only thing I bought was a light case as it is slippery without one and I picked up a $12.88 QI charger to use at work.
The phone already gets better battery usage than my previous Note 3 with a larger battery in it.
Stand by drain is high.... s not really relevant.

[Q] Bizarre Battery Drain

Dear XDA Members,
I'm having some issues with the battery of my Samsung Galaxy S4 Mini. About 2 weeks ago, 2 phones in this house, a Samsung Galaxy S4 Mini and Huawei Ascend P7, started (quite simultaneously) to have battery issues. They both are on the stock rom and are not rooted. To sketch the degree of the issue: the Huawei had about 40% after 7 hours standby with 3 minutes screen on time. The Samsung lost 65% in one night just being idle.
At first we thought it were the phones that were having the issues, so we returned the Huawei to the shop (about 40 kilometers away). The people of the shop called yesterday, saying that the phone is lying in the shop for over 3 days now, still having 40% percent of battery. This made us think it was something with the antennas here in the neighbourhood.
In the mean time we had already bought a new battery for the Samsung (an original Samsung battery), and I have performed a factory reset. The battery still drains quite heavily when airplane mode isn't enabled. However, last night the Samsung still lost over 15% with airplane mode enable and all recent apps killed.
I completely lost track about what the issue can be. To me it seems that the fact that the phones started having issues at the same time is caused by an external factor. But in that case, I cannot explain the 15% overnight battery drain on the S4 Mini on airplane mode with a new battery. Should I return the Galaxy S4 Mini to Samsung to have it looked at and fixed, or should I try some other things first?
If anyone wants some more information about the issue or the devices, I'll happily provide it.
Thanks in advance!
Note: It is not my intention to root the S4 Mini or push settings to the limit to have 0% battery drain, I just want 1 or 2 days of battery life again, depending on the usage.
Edit: There are also a OnePlus One and Galaxy Gio being used in our house, who do not seem to have severe issues. This confuses me even more about the external factors (antenna failure?) that might be draining the battery. We all have the same provider...
There are many ways to save your battery life:_
some of them are as follows:---
***Go to recovery and clear cache this will help improve the battery.. Use clean master from play store, which will disable / stop unwanted apps, clear app cache.
***Try using Greenify
***I recommend GSAM battery monitor app from play store. It's very easy to understand and is very good at locating battery issues.

Dear XDA Members,
I'm having some issues with the battery of my Samsung Galaxy S4 Mini. About 2 weeks ago, 2 phones in this house, a Samsung Galaxy S4 Mini and Huawei Ascend P7, started (quite simultaneously) to have battery issues. They both are on the stock rom and are not rooted. To sketch the degree of the issue: the Huawei had about 40% after 7 hours standby with 3 minutes screen on time. The Samsung lost 65% in one night just being idle.
At first we thought it were the phones that were having the issues, so we returned the Huawei to the shop (about 40 kilometers away). The people of the shop called yesterday, saying that the phone is lying in the shop for over 3 days now, still having 40% percent of battery. This made us think it was something with the antennas here in the neighbourhood.
In the mean time we had already bought a new battery for the Samsung (an original Samsung battery), and I have performed a factory reset. The battery still drains quite heavily when airplane mode isn't enabled. However, last night the Samsung still lost over 15% with airplane mode enable and all recent apps killed.
I completely lost track about what the issue can be. To me it seems that the fact that the phones started having issues at the same time is caused by an external factor. But in that case, I cannot explain the 15% overnight battery drain on the S4 Mini on airplane mode with a new battery. Should I return the Galaxy S4 Mini to Samsung to have it looked at and fixed, or should I try some other things first?
If anyone wants some more information about the issue or the devices, I'll happily provide it.
Thanks in advance!
Note: It is not my intention to root the S4 Mini or push settings to the limit to have 0% battery drain, I just want 1 or 2 days of battery life again, depending on the usage.
Edit: There are also a OnePlus One and Galaxy Gio being used in our house, who do not seem to have severe issues. This confuses me even more about the external factors (antenna failure?) that might be draining the battery. We all have the same provider...

In settings>battery check your mobile network signal of last night and see if there is any app that is sucking your battery.
You should try greenify but you need root access.
Thanks for your answers. If the problems do not get solved I will indeed try some of those apps (I've used Greenify earlier, I know it's great )
I've monitored the apps draining the battery, and in fact there aren't many apps that use a lot of battery. It's mostly the screen or mobile radio active, which makes me think it's something antenna related.
I've spoken to my neighbour who is a customer of the same provider, and he indicated he has issues to since a few weeks. I mailed to my provider and see how things turn out
Thanks for your tips!

Yeah i also think the problem is in network quality, you should try another sim for some time and see the difference.

Display drains battery in no time - hardware issue?

As I just sent my Galaxy S7 back to Samsung for repairs, I had to break out my trusty red Nexus 5 again. I got it up and running with Oreo 8.1 in no time (thanks to the xda community, as always) and so far, it's holding up well for a four-and-a-half year smartphone. Only the issue why I originally replaced it still annoys me, and that's the battery.
Whenever the phone is sitting around, it barely uses any battery - it can be sitting around for over one hour, WiFi and BT on, getting notifications etc., but the battery maybe loses one percent. If I have a phone call, I maybe lose 1% every 5 minutes or so - that's still fine by me. However, as soon as I am "using" the phone and keeping the display on to read emails, text, or browse the web, the battery plummets and I can use up 10% in 10 minutes.
It almost seems like there is a hardware issue with my display causing the extreme power usage. I am on my fourth battery - the first one was replaced with one from ebay (said "original, but you never know) when it didn't last over a day anymore, that improved it for two months or so before it degraded again. Then I decided to spend 40€ on a genuine one directly ordered from LG's spare parts site, but that also only held up for four months or so - and now I'm using a battery from ebay again which has been used for maybe a month (and then sitting around, being charged occasionally), but I struggle to make it until 6 pm without recharging.
Do you have any idea what could be wrong with my phone? Could it actually be an issue with the display itself?
Thanks!
Could be the ROM that is causing the battery drain. Maybe try it on a stock ROM?
