Battery life and Charging time

I've owned the Samsung Focus S now for 12 days. I came from an android bionic. I have owned Windows Phones before, the Venue Pro and the Hd7. But this is my first Samsung.
For the first few days, the battery life was fine, a full day. But this past week I find my self hard pressed to reach a full work day. I don't play music during the day nor do I have many, if any calls. Mostly SMS and internet.
I've turned off as many background tasks as acceptable, limited the number of live tiles, set brightness to auto, and check email off of push. Yet this morning I reached 20% in about 8 hours.
In addition, I find the time to charge is extremely long. It might take 4-6 hours to fully charge from 80%.
Is this normal for a Samsung?? My other windows phones, and my bionic certainly do no present the same battery problems as this one does.
Thoughts, or is this usual?

Do you have wi-fi turned on? This is a real battery burner...
My Focus S usually goes through about a day and a half before I need to recharge. That's with a few phone calls, some messages, a bit of wi-fi browsing at night, etc. Email only gets checked every hour but it's on 3 different accounts.

while I'm home WiFi is on. Away from home its off. This is normal behavior for all my phones. All of them last at least 18-24 hrs, under the same condition.
Took it back to art. They said , lets try a different battery. I'm willing to try it for now.

I just wanted to add to this as I seem to be experiencing a similar issue.
I purchased my phone at the end of Dec, it's been great.
Now, since around a week ago I've been having issues. I used to get roughly 2 days use per charge and it used to charge quickly.
Now, the phone runs hot, the battery drains in 6 hours or less, and it takes many hours to recharge.
I turned off the one app running in the background. I turned off wi-fi. It doesn't seem to help. The battery itself doesn't seem to be too hot, but it's hard to judge.

I did a factory reset, and got a new battery. I then reinstalled less than half of my existing apps. In addition I've set my display brightness to medium.
Battery life has doubled, and the charging is much quicker.
Read an article yesterday about ads in free apps eating about 35% more battery. Who knows.

Even if they're running in the background? My Focus S takes a lot of time to charge and decharges so fast. 35% is no joke.

I'm also having some kind of battery issue, I have 2 batteries and they are both 100% charged but by the end of the day one is completely dead and the other is about 20%. I use my phone a lot for music and browsing over 4g and WiFi, but I charge by battery to 100% then go to the battery saver setting and at 100% it says time remaining about 5 hours. An when I turn on battery saver it says about 6 hours. On a full charge this seems crazy. Also with the homebrew battery monitor app. It says my phone is using over 4000mV. With screen set to low and in airplane mode. This is wierd.

4000mV? I assume you mean mA? not mV? 4000mV is only 4V which is about right, your voltage shouldn't change much, perhaps +-10% tops
if you do in fact mean Amps...
4000mA is 4A an hour, your battery would be dead in about 20 min at that rate and probably in fire as well
So, lets look at this in a different way,
2 batteries, that's about 3.3Ah max, you only had about 20% left in one which is approx 330mA so lets call it an even 3A of juice burned during your day.
An Average long day at work 12 hours
that's 250mAh current draw every single hour of that 12 hour day.
250 is quite high, but normal with the screen on and high brightness an wifi, however that isn't normal if you are normal and don't sit at your phone each hour for an hour for a whole day.
Things that can send your phone off on a amp burning spree? most common one is the backlight, set it to auto, and have a dark /black theme, AMOLED is the opposite to normal LCD screens where having a white background was best,
Next up is your signal strength, low 3G signal will eat your battery (4G is worse but thankfully we don't have that)
keep battery saving on all the time, it only kicks in when it needs to but I have seen dramatic differences having it turned off even with a full battery, im not sure what it changes when its not down to low battery but it does something.
background tasks can play a part but are minimal on WP.
I have 3 accounts on push sync, wifi and Bluetooth always on (but not always connected), I use it a lot during the day including several phone calls and web browsing, I start work at 8am, finish at 7 or 8 PM and im still sitting with 50% battery...
that works out at an average of just under 70mAh. that's about the normal level id expect, its double that if I turn battery saver off (even though it wont kick in until the last hour of the day)
oh I can make it go quicker when I show off the full capability's of our screens too

Battery Drains during Standby Mode

Does anybody experience a 3% to 5% battery drain just a few minutes after charging the battery to 100%? It has already reached 100% so I already unplugged it from the charger, but then I noticed after a few minutes, it went down to 97% already, and then in 10 minutes, it's already down to 96%. In 3 hours, it's down to 84%; in 7 hours, it's down to 38% and that's just on standby mode with Wifi/Bluetooth OFF, 3G OFF, GSM only. I've been experiencing this problem for the past few days now. I've already conditioned my battery, charging it to a full charge (100%) after draining the battery until it shuts the phone off. I only charge the battery while the phone is off and usually it takes about 3 to 4 hours maximum to charge it to 100%.
The longest time it reached was 12 hours (battery unplugged from charger) and that is with light use, such as Wifi is only on for a couple of hours, so basically just 2 hours web browsing and skype, 10-20 text messages and 30 minutes to 1 hour browsing the photo gallery or watching videos. No phone calls and 3G is off. The rest of the day, the phone is just on standby mode. I only have at most 10 widgets on the home screen. I have Avast Antivirus running in the background.
I am currently using Easy Battery Saver, Easy Task Killer, GO Task Manager and Battery Monitor Widget. I've uninstalled Juice Defender since I don't think it helps that much when it comes to the battery drain. Currently, the power saving option (available on Note) is enabled at 50%.

Any feedback or comment on this matter would be really much appreciated. Thanks!

From a personal standpoint. Your screenshots shows that your phone had never ever done a deep sleep at all. the 'Awake' mode is continously consistent as well. I guess the probable reason for that is you've installed ''Avast AV" on your phone. It's always running in the background (whenever the phone is ON). From my experiences, Any background application running would always cause wakelocks and the phone would never enter into deep sleep at all.
How bout you try uninstalling some of the background apps your using esp. Avast AV and give it a day to observe if your still having that battery drain issue. (Don't forget after uninstalling or removing those apps, try to wipe dalvik cache and battery stat and restart your phone after.)
and Oh by the way, I am using Juice Defender and contrary to your saying it doesn't help.. IT DOES HELP save battery as I my Note is able to reach 1.5- 2 days of normal use.
Cheers!

Yeah and download betterbatterystats and do some searching on it. With it you can discover what is causing those wakelocks. Search the web for more info on your wakelocks.

I'm using avast and never seen a drain like that. Only time I have is because of background processing. First thing I would do is turn off Background Data
Then as others have said - check batterystats to see where wakelocks are
Plus a rooted phone is a good thing. Titanium backup allowed me to freeze wi-fi sharing which also made a big difference
Finally - clear all caches from Applications menu and reboot

Only picture that shows that is the one with 1 minute 56 sec discharging time, so it was taken shortly after taking charger out. No suprise of it being almost 100% screen on time there if its only 2 minutes

Also installing "cpu spy" will give the cumulative time that your cpu spent at each frequency including deep sleep , mine is showing 88%
John.

Anti virus app is battery hog, I had avast before too, and I uninstalled it after 2 days using. Also that Juice defender, from my test before, it use up more battery than it saved. turning on and off those 3G/Wifi thing is using up alot of battery. and you know what? even the betterbatterystats use up alot, at least to me, becoz it scan what is up frequently.

Hello! Thank you all so much for your response. I've installed both BetterBatteryStats and CPU Spy and here are the results (please see attachments). Upon checking CPU Spy, it shows there that phone did went to deep sleep, maybe? I'm not quite sure, but it shows on the screenshot that it went to deep sleep for 19%. So does that mean the phone really went to sleep?? I'm sorry to ask this question, since I've never really encountered this problem before with my previous Samsung Wave phone, how will you know that your phone went straight to deep sleep mode?
Also, after 46 minutes or so, the battery went down to 96% already after charging it. The battery drain was already 4% in less than an hour.
@letters_to_cleo: I have not uninstalled Avast yet, since I'm still hesitant to use my phone without an AV. But I will try your suggestion for 1 day and see if there's any battery improvement.
I'm looking forward to your response or suggestions. Thanks again!

i am having problem too with new battery original samsung ( made in japan, finished in korea) previously i use samsung battery made in china, finished in korea. charged it over night with power off. it only last 13hrs. my wife phone can last 30hrs.
i've used batterymix to check the battery usage graph, the usage graph drop very fast compare to my wife phone. i'll post some screen capture of the graphs.
another issue is i used once wifi sharing. after turning switching the wifi sharing off, the wifi sharing service always at the background even after many reboot. how to turn that off??

You might need a new battery. Any rechargeable battery has a finite charging cycle. Just a suggestion.

Hi, all! I just noticed that the battery drains still even during deep sleep mode. After 3 hours or so (during sleep mode according to CPU Spy), the battery went down to 92%. It drains even faster when the phone is in use, especially when Wifi and Bluetooth are on, maybe 2-5% drain in 1 hour.
Maybe there's something wrong with the battery?? It's still a new battery and I can see some improvement each day though, but that's because I use it less each day. Before the battery can only last for 8-10 hours, then it increased to 12 hours, and then to 16-17 hours. BetterBatteryStats' current estimate to empty is 24 hours as of today, but that's because I only used the phone today for only a couple of hours, with 20 minutes Wifi and Bluetooth ON and most of the time, it's on deep sleep mode according to CPU Spy.
What do I do with the results from the Partial Wakelocks? Do I have to disable those apps?? The Kernel Wakelocks didn't show any reference apps running. The screenshots for the Partial and Kernel Wakelocks that were taken a few hours earlier still show the same results after 3 hours.

That would be really bad luck. I got my Note via preorder in Germany at the first day it was sold and since then I charged it everyday, sometimes even twice and there is no difference to the first day. If I get told by Samsung after 6month of normal usage the battery is dead that would be the last Samsung device I bought and I use a lot of Samsung stuff.
@ebichan24
Your last screenshots show between 9:35 and 13:35 5% of battery drain. That's not really a good value but ways lower than before. Did you delete some Apps or what did you change?
And since when occurred this issue? Did you install new Apps before this happened?
On my Note I had this issue sometimes without any changes but it was gone after a reboot.

Agreed with Kanalcommander.... try a reboot in the first instance.
Others have also noted that it takes a few refresh cycles before the phone more accurately reports battery use. Perhaps what you are reporting is because the phone and battery are new (new ROM or Kernel loaded?)
What I have done in the past is to reboot into CWM recovery then clear the battery stats (in the Advanced menu option) Recharge the battery to 100% until it says to remove charger and then use normally until battery down to around 20%, then recharge the battery to 100% again. Do this over a few days and that may help.

thanks, it is new battery two days old.

I was having similar problems with my new note and finishing full charge in 12 hrs but fixed some things and my last charge gave me 2d6hr seriously..few things i did were stop using live wallpapers! Get badass battery to thoroughly monitor stats and then use zdbox to extend life even much eg. I put phone to auto flymode using that app when its sleeping time rest i am more than satisfied even if on GB LC1 fw..waiting for official premium suite for ics since i recently upgraded from sgs2 using ics i miss that smoothness and much better bat life.. Let me know if can be helpful.. Good luck

@TempusFudgeIt
That's what I'm currently doing right now, well, actually, what I do is I discharge the battery until it reaches 0% and turns the phone off. And then I charge the phone for 3 hours while it's switched off, I turn it back on again to check if the battery is fully charged and then I unplug it from the charger.
@Kanalcommander
**Did you delete some Apps or what did you change?
I haven't deleted any apps yet since I don't know which app/s to delete. Most of the apps I downloaded in Note were the same apps that I used in my iPhone4 and Samsung phone before.
**And since when occurred this issue?
This issue occurred since the first day I bought the phone, which was a couple of weeks ago. How long does it take to condition a new battery and new phone?? I'm sorry if I have to ask this question, it's just because I never really experienced this problem with my previous smartphones.
**Did you install new Apps before this happened? On my Note I had this issue sometimes without any changes but it was gone after a reboot.
I only installed recently CPU Spy and BetterBatteryStats and that's it. The drain of 5% from 9:35 to 13:35, the phone's just on deep sleep mode. And then from 13:35 to 23:44, it went from 92% to 74% while the phone is on deep sleep mode at 90% according to CPU Spy. That's 18% battery drain. It's just an unacceptable number for me. I tried rebooting the phone already, but every time I do so, just a few minutes after I turned the phone ON, there's already a 1% drain in the battery.
Also, does the battery really drain faster when the Wifi is ON? I've read in other threads that there might be some problem with the recent OS update that Samsung needs to address. Is this true?? Because as you can see on the screenshot below, the battery was still at 74% by 23:44 and then after I turned ON the Wifi and used it until 01:26, the battery went down to 54%. That's already a 20% battery drain in just less than 2 hours. I was only browsing through the Android Store and Skype.

Calibrate your battery in case you flashed any roms and for first usage I got my battery to 0% 3 times then everything is running great for example its at 47% now its 22 now and I have had it off charge since 7 morning..... i have wifi gps and 3g always on and use music player bluetooth and made some calls

My battery (also only a week old) drains quickly too. Can anyone tell me if widgets draw a lot of current? And then is it only the ones on the visible screen or do all widgets draw juice all the time?

I will ask such thing, did you guys check the battery expiration day ? Mostly sibce you got your phone almost a yeae after it was announced you nay get a bad battery, as for widgets the ones that are always active and asking for informatiom. Like location or weather over the internet yes they do eat your battery kinda fast.

Recurring battery drain? - Caused by memory of using app to drain battery?
Hello!
I used a battery drain app when charge left was 30% to accelerate drain to "die out" stage. After I completed the calibration process for unrooted phone as suggested in various sites (charge fully, switch off and charge etc.) I started using it from a 100% stage.
This afternoon when the battery showed 30% I saw in BMW the current flow was in -10ma to -15ma and it started spiking to hundreds. There was no change in settings or usage. From the 30% level it dropped to 10% in an hour and I had to charge again.
Was puzzled why the battery which was dropping around 0.5%/hour in standby earlier to the 30% level suddenly went down hill. My first guess was it was possible some file in the system remembered the previous usage history and replayed it out.
Any suggestions? Anyone faced this before? Everyone says LiOn batteries dont have memory so if anything it has to be the phone.
Thanks!

Battery taking a nose dive since 4.4.2?

Not sure whats going on but the battery on my Note 3 is horrible since the update. I fully charge it and 1 hr later (not even using it) I've lost 5-10%. It barely last the whole day now. I've even wiped the device and it continues to happen. Doing a quick test right now, fully charged its been off the battery for 20 mins and I'm showing 27% usage on the Android System, 10% on the Android OS and 15% of the screen and its down to 97% already.
Any ideas?

things to try: (no this isnt a 'disable anything useful like email and google plus' post )
1. camera - there is some well documented issue, if you open the camera app, there is some kind of battery drain going on. google it, there is tons of reading material for it. temp fix is reset.
2. I have noticed google now makes my battery life do what yours does, drop 10% easy in an hour of it being completely idle. open the app, disable google now, and then see what is going on. i hate disabling anything but its worked for me.

Thanks after a second reset it seems much better. Maybe it was one of my Apps? For now I'll just install them 1 at a time.

Same thing happened to mine. Went to bed at 95%, killed all apps, empty ram, turn off data but left wifi on. Woke up 8 hours later and it was down to 17%. Unprecedented 10% hour drain. Usuallly it drains 3 -5 percent overnight. Same thing happened to wife's phone and she is on Sprint but she left wifi and data on. Uninstalled Google camera and Skype and notice it went away. Testing it again tonight.
Edit: Test it again last night. 4% drop in 8 hours. Woke up to 96% this morning. Hopefully that fixed the problem.
Update: Went to bed at 11:30 at 68% and woke up 7 hours later and battery is still showing 68%! Surf the web for 5 minutes before battery drop to 67%. Amazing standby battery drain. I had turn off wifi, bluetooth, and data before going to bed and killed all the apps. Usually this will cause a .5%/hour drain but it barely drain .5% in 7 hours this time!

Battery Issues

Hi All
I bought Nokia 7 Plus yesterday and set it up, but the battery drain so fast. I left my phone to sleep with wifi on throughout my sleep it drains 10% with just pushing notifications from FB, like everytime I will get FB Notifications and not open it it will drain 1% of the battery.

Remove fb and see magic

U just answered to your question. It's not the phone, it's just crappy facebook app.

Facebook Lite is the way to go if you need FB, I think - normal version eats battery a lot, and I'm not sure if that will be fixed at all - seems like they don't care.

If you have to use Facebook, use Facebook lite or alternative apps like Friendly.

Hi, I got Nokia 7 Plus yesterday and started using it today. Initially with the battery percentage came with package, battery draining was slow. After doing first charging from 21% to 100%, battery is draining too fast. It is common for some batteries and takes some charging cycles to get battery optimized. If battery draining is happening too fast even after 3 to 5 charging cycles then there would be some fault with battery.

I got my phone day before yesterday & its now running Android 8.1 with the May security patch. Since the time of use, I've charged my phone only twice & both times charged it up to 100%. I feel the batter is draining. Please have a look at the screenshots and let me know if the battery consumption is fine or its draining fast. The battery dropped by 1% in 4 mins of the phone being idle with the display closed. Also the stock camera app is consuming a lot of battery.

I can confirm a very hard drain, too. No way to reach 7-10 hours of usage.

i'm getting about 5-5.5 hours of sot with moderate usage... Checked the app usage..where it shows PUBG used 12% battery in 38 min, 45 min of youtube drain 8% 26min Instagram drain 5%...I don't use fb much on phone when needed i mainly use fb lite... .i don't use auto brightness. so my brightness level is always 45%.. in overnight( well it's like 5-6 hours) battery percentage dropped 4%.. Wifi is always on and GPS is always on high accuracy.. in power saver 19 apps are allowed for background activity...

Battery drain
I just purchased my phone yesterday and used it for some time. I put it on charging at around 20% and didn't use it until full charge. After it got completely charged and then I just used it for few mins it went down 100% to 95% very fast; later after few mins I started suffering net and did misc stuff for about an hour it went down to 85%. Next morning I saw the battery % was 81%. Is this normal? I mean how can it last for 2 day as the company claimed. Aslo I am android 8.1.0

This has been a comman issue with Nokia 7 plus, including me. My battery had high discharge rates in both Oreo and Pie. However, post March security update, I am seeing some good battery life. I would also suggest to update to Pie and update Device Health from Play Store. Hope it works out for you.

try letting the battery drain to 0% then charging it to 100

TA1062 with build 00WW_3_51F here.
Before the march update, the phone could last for almost 2 days with moderate usage.
After the march update, I barely have 5 hours of standby time, and like 2 hour of usage time. This is crazy ! Not heating, but also randomly shuts down while it says like 65% remaining battery. I haven't changed anything else !!!
Does anyone have any idea how to improve this ?

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Samsung Galaxy Note 20 Ultra's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

I find the stand by drain right on par with my Note 10 Plus. It was fully charged at 7 PM last night and this morning at 6 AM was at 95%. I installed Nap Time by Francisco Franco with a couple of adb commands for the aggressive doze features.

Went to bed last night at 1am at 100% battery. No apps are running, i have a bixby routine that puts the phone into power saving mode while not in use over night. Woke up 7 hours later at 8am and the phone had gone down to 93%, so it has gone down 7% which is 1% percent every hour being lost. Looking at app usage nothing was running in the background this entire time. Had my device for 5 days now so has gone through learning stage. This is ridiculous standby drain, is anyone else having the same issue?

Yes my drain is also bad. Are you guys running Snapdragon or Exynos?
I am Exynos unfortunately.

Can any one try standby drain after installing naptime? Let us know if it helps reduce the drain.

I'm using Naptime and I think it does help with standby drain. it is in the par with note10 at around 6-7% over night.

Can you share your settings? Do you run naptime the entire day or schedule it only at night?

I run it all the timed. Here's a screen of my settings, I don't disable BT on doze as I have my Note connected to my Panasonic home phone.

For me it was much worse, about 3% per hour during sleep! I just deactivated VoLTE calls (and also the 5G just in case) and it's much better all of a sudden! Can you try this, maybe it's the same problem for you?

Went to bed last night at 1am at 100% battery. No apps are running, i have a bixby routine that puts the phone into power saving mode while not in use over night. Woke up 7 hours later at 8am and the phone had gone down to 93%, so it has gone down 7% which is 1% percent every hour being lost. Looking at app usage nothing was running in the background this entire time. Had my device for 5 days now so has gone through learning stage. This is ridiculous standby drain, is anyone else having the same issue?

Motion smoothness is the culprit
I have been playing around with Note 20 Ultra (T-mobile carrier locked version - SM-N986U)
I turned off 5G (Connections --> Mobile Networks --> Network Mode --> Switched to LTE/3G/2G (auto connect)
But even with 5G off my battery drained this morning while only have google maps open 10% in 45 minutes!
All my apps that I frequently use I have gone one by one under battery usage and selected put app to sleep.
My power mode was at optimized with so I lowered it to Medium Power saving and that looks like it took care of it.
If I go back to Optimized but keep motion smoothness at standard then the phone seems to handle battery usage much better (this is all with sync on for email push).
It much more on par with my previous Razer Phone and closer to iPhone XR territory.

Amazing. Only discharges about 0.5% per hour. Thats with always on display turned on.

Wow..you could be the first use reporting this less standby drain..I have 1% per hour with Always on and 0.5% without Always on...any special tweaks you did to achieve this?

My mistake on this. My Always On Display is set to tap to wake only.
However to get best battery life possible with Always On Display set to be on full-time, turn off auto brightness, then you can manually set the brightness down the lowest setting.
That might get you down to 0.75% per hour, but I haven't tested that myself on this phone. However with my S10+ I did that and it helped a lot. Only downfall is you can't see Always On Display in bright sunlight. However indoors is usually still visible.

Got the phone (n20u exynos) yesterday at around 7:45 pm. It had 64 percent battery. Did the phone setup, sync and played around with dex. The phone got warm. Went to sleep at around 11:30 and the battery lasted me till today morning 6:30, with 2 hours sot. Don't feel its that bad. I also think it might improve further as it is still in the learning phase.

i avg .9-1.0% a hour with screen off over night..

Use Samsung Members app

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Samsung Galaxy Note 20 Ultra's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

if you're having an issue with battery drainage, report it to Samsung directly via Samsung Members app.

Snapdragon. Switch off wifi and normal powersaving mode with 5g still on.
7hrs sleep time, consumes battery 4%

I'm losing 4 % each to Google and Youtube, though the apps aren't running. I've forced them to sleep when not being used and hoping that will slow the drain. I'll have to wait a couple of days to see if that has helped.

About 4% for a 8.5 hours of sleeping, not bad [emoji6]View attachment 5097301

How do you know its 4%. i think its more. Also on a personal note Who uses Tinder bro? Get rid of that crap. Plenty better stuff out there. Not to offend everyone has their own taste, i just said it on a light note.
