Hey guys So even though the battery life on the g5 plus is amazing, I'm not quite getting the battery life other people on here get. So I checked the battery thing and saw that cell standby uses a lot of battery even though I only have 1 sim card installed.
Specifically, cell standby has used 18% of my battery so far and I am at 10% charge right now. It's been 24 hours since my last charge. So I wanted to ask, at 24 hours, how much of your battery is consumed by cell standby?
Or rather, say how many hours it's been since your last full charge and how much % is used by cell standby.
mine is somewhere in that range, but the overall battery percentage is very very low (1% every 2 hours or so on good days).
Keep in mind there are 2 important numbers here.
1) Battery percentage lost (IMPORTANT)
IF your battery loses 10% an hour, this is a big deal. IF you lose 1-2 an hour, you are good!
2) Percentage by service (MUCH LESS IMPORTANT)
This is helpful to diagnose rogue apps or services, but is much less important, unless #1 is very high.
Remember, 25% of a 1% loss over 4 hours (random number here) is still practically nothing.
#2 does not matter at all (generally) if #1 is an acceptable % drop.

Thanks for replying. I asked someone for a screenshot of their phone on this and I saw they have a 4% drain over 19 hours. I have an 18% drain over 24 hours.
4%/19 hours = .21 per hour and a little over 1% per 5 hours.
My phone consumes 18%/24= .75% per hour.
So the difference is very significant here and it clearly is a problem. A extra chunk of battery is never a bad thing.
ok. wanted to double check that real quick.
What about coverage? low coverage puts a pretty heavy drain on battery, and I have seen this reflected in Cell Standby. also, are you using Wifi/is it on all the time?
Cell reception plays a huge roll too and whether you're on wifi or not. And if you're constantly turning your screen on. When the phone detects it's in the pocket or just sitting there it'll go into extreme power saving mode (thanks to nougats "Doze" feature). That person who only got 4% drain over 19 hours most likely had their phone just sitting there and never touched it. At that point I would ask the question, why do you even have a phone?

My wifi is always on. I haven't had a problem with cell coverage ever with any of my previous phones. I'm going to try using this app "Gservicesfix" from the store and see if that fixes my problem otherwise I'll do a factory reset.

My reception is fine.
The person who's screenshot I saw definitely does use his phone a lot. He has like 28% drain from screen.

I am still not too happy with the battery of the Galaxy, even though it should be conditioned by now. Nowhere near as good as the iPhone 3Gs, even though the 45nm chip in the galaxy, as well as the AMOLED screen, should be benefitial to battery life.
Maybe a good benchmark would be to see what readings people get at the time of the first "Low Battery" warning. You can see what depleted your battery by going to Settings/About/Phone/Battery Use. To get details, touch the corresponding bar in the graph.
Mine are:
20h 32m 4s since unplugged
Display: 38% (1h 54m)
Cell standby: 24%
Phone idle" 16%
Android OS 10% (CPU usage 50m 4s)
Voice calls: 6% (2m 54s --- WTF?!)
Android System: 4%
K-9 Mail: 2%
Advanced Task Killer: 2%
Those numbers look good to me somehow, I wouldn't expect better battery life after using the display for 2 hours and another 19 hours of standby? Especially as the phone can easily stand by another few hours on the last 15%...
i just got my phone recently, i'll post my results after a few weeks of daily usage.
i do a lot of 3G+, WiFi and SMS, not so much voice call, but regularly enough like two or 3 calls a day
that should be a pretty good test to see how long the battery last from full to like 20% that's when i usually recharge my phone if i don't carry a spare battery with me

It depends on what you compare it to, I guess.
I am comparing it to my old iPhone 3Gs, which would last about 48 hours, usually with considerably longer talk time than the 2m 54s I have on the Galaxy S. How can less than 3 minutes of talk show 6% battery drain?!
As I noted, the Galaxy S's smaller die (45nm) and AMOLED screen should be an advantage over the iPhone 3Gs's older hardware, yet the iPhone lasts markedly longer.
Anyway, I just wanted to see what others are seeing and how long their phones are lasting. It might be interesting to many others, too.
The galaxy S holds considerably longer than the iPhone 3GS. Probably longer than the iPhone 4 as well.
My current stats:
2D 0H 33M 41S Since unplugged
Voice calls: 34% (38m 37s)
Cell Standby: 28%
Phone idle: 19%
Display: 18%
Funny, it doesn't show the time when i played SandStorm and Asphalt.
Oh, and my current battery level: 66%
If i skimp on the battery, i can hold 5 days between charges.

WOW! This is just amazing!
How long was your screen on for only 18%? (I have mine set at the dimmest, but still....)
Do you use email much and if so, how many accounts and often do you have the phone checking it?
Wait, you use tons of WiFi and you're suprised that the phone won't hold too much?
In contrast to the iphones that require you to manually search for a network, android ACTIVELY searches for local open networks and connects to them.
When you're not using WiFi- TURN IT OFF.
If you're talking about cellular internet, that's another thing.
And the display (set to medium-low brightness, the brightest mode where it doesn't BURN MY EYES. Damn this display is bright) registers 1h 27m.

For what it's worth, my WiFi has been off for most of the day.
But, on WiFi discovey, my experience has been the opposite.
On the iPhone 3Gs, I always had WiFi and BT turned on. if I was not connected to WiFi, but WiFi became available, the iPhone would bring up a pop up, asking me if I want to connect to the network.
With te Galaxy S, I can have WiFi Notifications on, but unless I search for a network (usually by turning WiFi off, then back on), it doesn't inform me of available networks.
To boot, even though it remembers both my home and office networks, half the time it does not sign in automatically when I enter the area, but I have to do the off/on thing to get signed on

Well consider yourself lucky! you got an amazing battery from the future or something, because this is not what we are all seeing... I get a decent 30 hours with mine max...
Can you tell us how long is the display time ?
My guess is that I could stay 2 days with my phone if I was never swithcing on the screen.
The thing is that you seems to use your phone like I was using my old nokia 6310 ...
Try to play some music or video and you won't last 5 days or even 2days ... maybe 1 if you are lucky
Basically you have left your phone switch off 2 days and call 38mn and that's all ?? I can't tell you that my old iphone3GS is going to be pretty close in term of performance of battery
given that 1h54 give 38% of 85% for the OP I would say that you have maybe 20mn of display
The battery life of my SGS was terrible for the first few days of use. I don't have the battery usage numbers but the battery would only last for around 20 hours doing: 30-60 min call, 2hour music, 30mins video, 30mins game, and approx. 40mins web surf using mostly wifi.
But after about 5 charging cycles (discharging until battery ran low and the phone eventually turns off, then charging the phone to full), the phone lasts for two whole days with the same usage described above each day!
So I have noticed a significant improvement in battery.
If you haven't gone through the charging cycle and your phone is relatively new, give it a week before you think the battery life is crap
yeah I am still waiting for the improvment
After almost 2 weeks , a dozain of cycle I still don't see it coming ...
I guess I must be using the screen too much ( miminum light) ...
Afert 12h46 I am at 25% with 65% taken by the display , 10% by cell idle, 8% by android , 6% by network idle, 4% by call ...
I have already used the screen 3h14mn
I don't know what you do but on my side I am reading my mails, reading xda, reading some newspaper on the train, watching some video ...
So my crappy battery doens't seem to come from some app draining it ... but just from the display.
So basically nothing I could do except using it less than what I am used to
Display time was 1h 27m
mine last around 10h (display on 4,5h) and thats as low as u can adjust brightness in settings according to gsmarena blog display can last up to 10h...
im using dimmer app now. hope i get 5-6h (display time) with that.
ok i'll play:
10hr:10min since last unplugged.
Battery at 74%
Display: 50% (I leave it on auto brightness)
Cell Standby:19%
Phone Idle: 12%
Bluetooth: 8%
NDrive: 7%
Android System: 2%
I'm happy with that.
I'm easily getting through a 15 hour day with moderate use (my normal usage pattern). this is on a par with my previous Nexus One and iPhone 3G.
BTW, I keep the WiFi on persistently (even when the screen is off) because I heard it draws less juice than the 3G/phone data. (I typically spend a lot of time around the house on WiFi ...)
Battery killer is normally "time without signal", the N1 would average maybe 70% without a signal, the SGS is averaging around 30% without a signal - so based on that perhaps the battery isn't quite as robust as the N1 (which was on Froyo).
Anyway, I have no concerns about my SGS battery based on similar phones and usage patterns. I will be tempted to get an extended battery for it though (I had a Mugen 3200mAh on the N1 and that would give me 2 days under quite heavy usage).

Are you sure about this? I thought I noticed much better battery life when I started to switch wifi off and using 3g instead. I guess it could just be my battery maturing

Keeping the WiFi policy to never disconnect apparently uses less battery than the system thrashing between 3G and non-3G data when sync'ing etc. Typically WiFi will show as 2% battery usage at the end of the cycle.
I base it off my old N1 usage, which I got from here:

I know there have been many threads like this but I'm just looking for clarification as this is my first Android phone. At my house I usually get the Rogers H speed with 3/4 bars. When I browse the Internet for just an hour, 15% of the battery has been drained. Is this normal on these speeds?
I plan on leaving an IM client on 24/7 and using GPS/maps daily, so I am a bit worried because this may not last the entire day. I could switch to EDGE when I don't need it but apparently I heard that will disconnect once I start a voice call (and want to keep my IM on always). I checked my battery stats and apparently the cell standby (H) is taking most of the battery.
I am using CyanogenMod 6.1.1 with stock radio from Bell. I'm going to try to see if SetCPU makes a difference. And is there any program that can limit the HSPDA bandwidth so less battery is used? Thanks.
call *#*#4636#*#*
If you are at home or in a Wi-Fi accessible, Turn ON wifi - it uses wayyyyy less battery than the phone radio when it comes to Data....
you could get a extended battery.... Mugen Power has one for 1800 mAH and its the same size as the stock battery so no need of a bigger door.
What is your screen brightness set at? The screen is one of the top battery drain culprits. Try turning off auto-brightness, and turning the brightness down to as low as you find tolerable (depending on personal taste, and the lighting conditions in the places you use the phone the most). I recently just lowered my brightness to 35% (still plenty bright under many conditions) from 45%, and already noticing a significant improvement in batter life. Battery usage of the display dropped from over 70% to 45-50%. I haven't had the brightness set this low long enough to see how it translates to hours/days between charges, but we'll see how it goes . . ..
my battery life is retarded. probably less than yours. i swear i think i lose 1% of battery per minute of web surfing. battery is fine if you do not go on the web and have 2g on all day.
Yeah, it's pretty bad.
But that's the same for most smartphones nowadays I think...
Back to the days of game gear, the battery muncher.
6AA = 5 hours of gameplay.
I just bought some Chinese 1500maH batteries on eBay and I don't know if they're actually 1500maH. If I play with my phone a bit, I get 50% after 8 hours at work. Yikes!

Assuming the screen was on the entire time, 15% drain for an hour of web surfing sounds pretty good to me. The main battery eater while using the phone is the screen, so I doubt messing with your connectivity is going to drastically change your battery consumption in this usage scenario. Changing connectivity to Wifi or EDGE would probably help more during those times when your phone is off but your phone is still connected to the internet.
On a side note, I had terrible idle battery life when I was using CyanogenMod 6.1.1 on my Desire Z. When I was using my phone, battery life seemed normal. But when the phone was on standby, it seemed like my phone was running even when it was supposed to be on standby. I suspect it might have been SetCPU constantly polling in the background. I switched to Virtuous and didn't install SetCPU/didn't do any overclocking and my life improved literally threefold.
Friend has a new Desire Z (bell, unlocked). Using it on AT&T network.
When at a house, and we use WiFI (30Mbps DL, 25Mbps UL), the speeds are VERY inconsistent. With my iPhone 4 using speedtest.net, it shows up as 20/15 each time. (WiFi is a little slower than the modem).
With the Desire Z, we get 15/10 (which is fine/acceptable). Then 3 minutes later we do it, we get 5/2. Without even moving the phone or touching the modem connection (not downloading anything on the computer), the connection just gets slower. Then it might be fast or slow, basically it's a toss-up.
The first time we noticed the issue is because when we are outside, we get HSPA speeds of 2.5/1.0, then randomly decreases to 0.1/0.05. HUGE difference. And VERY inconsistent. He is using a microSIM from iPhone 4, with an adapter, so we figured maybe the SIM card is getting loose at certain points? However, the WiFi is also inconsistent in addition to the HSPA, so it's probably not that.
What should I do? Is this the situation where I have to flash a new radio or something? (Please suggest others if I am wrong).
Thanks!

Also, his battery is kinda weak. The battery health is apparently clean/healthy. He came from an iPhone 4, where he would have 3G, WiFi, and GPS on at night but not actually using them. Wake up, and 3% battery loss, maybe 5. WITHOUT using them, just having them on.
Now, with the Desire Z, we have the WiFi + 3G on, but NOT the GPS. He is losing 20%-25% in 8 hours without even using the phone.
Information about battery shows a high Cell standby (25%) and Phone idle (25%) percentage. When going into Spare Parts > Partial Wake usage, we didn't find anything really fishy. BUT we had rebooted so perhaps some info may have been lossed. Should he just go to sleep tonight and report the Partial Wake Usage statistics again?
We have a feeling it may be some apps refreshing at night.. But he clears all the apps with Advanced Task Manager except for like Facebook (2 hour interval refresh), GMail, and Google Voice.
I highly doubt a 20% battery decrease overnight is normal.. My mom's Atrix only loses about 5% overnight, with the same parameters I gave before.
I thought it may be a bad battery, BUT the phone idle + cell standby are abnormally high.
Thanks!
Why is this in General as well as Q&A?
Put this in Q&A, didn't get any answers. Went to General, saw that more people posted there, even for Q&A's. Have an actual problem that research didn't help much with, so made a thread. If necessary, I would be glad to remove the thread on Q&A.
By the way, thanks for the answer .
Would you be able to post your software specs? Radio version, rom version, android version? My Bell DZ only loses about 3% per night if I don't plug it in to charge. I, like you, have wifi, gps and hspa enabled with no huge I'll effect.
The stock battery is usually alittle weak. Being a 1350mA, it doesn't have the capacity either, but that is why it is user replaceable. I picked up the mugen 1800mA battery that gives the phone the stamina to last a full day of full use or 2-3 days of light use. I forget how much I spent on it but it was definitely an upgrade.
As for the signal issues, we would need to know what you are running. The latest .30 radio is recommended for AT&T if I remember correctly. Also, the type of rom (stock or custom) might give us abit more insight.

I lost about 10% overnight today I believe, possibly 15 (don't remember exactly what I left off at).
Not sure on all the stats because I don't know how to check them but
Android Version 2.3.4
Cyanogenmod 7.1.0-RC-Vision (seller did it for me)
What is the radio version? I think that is baseband not kernel? If so its 12.52.60.25U_26.08.04.30_M3
-------------------------------------------------------------------
If anyone knows about the sporadic data, that'd be helpful. It does seem that if I go into airplane mode a few times it fixes itself, but I doubt everyone does that to ensure fast HSPA speeds

I've never used CyanogenMod Custom ROM's before, so I can't speak from that experience. I can, however, tell you that while running RMK (and team's) Custom ROM's (Virtuous, G-Lite, Unity) and now MIUI, battery life has been excellent, even with the stock battery. The current build of MIUI lasted for about 15hrs on a day of full use, RMK's ROMs would last about 12-15hrs of moderate to full use on the stock battery. Alot of the custom roms have different power management settings and tweaks, if you're comfortable with flashing, I would recommend another ROM and see if that helps with either of your problems.
If you like the Vanilla/AOSP look of android, try RMK's G-Lite ROM. It is very lightweight, fast and stable. I remember having one issue with it, but it was a very small issue and didn't stop me from using it for a few months.
I am currently on MIUI English 1.7.1 and with moderate use I am sitting at 50% charge spent over 2 days. Moderate for me is about 300 texts with about 10 phone calls and a total of about 4hrs of web browsing.
I can link you to those roms if you need, but they're all located in the Dev section. Your radio seems like it's on the right version, so perhaps it's not the issue. Try running another rom for a week and see if that helps to any degree.
I re-calibrated the battery, let it die, charged it up, let it die, charged it up. I followed the instructions to the letter and all that.
It was at 100% when I went to sleep. Woke up 8 hours later, 74%.
Settings > Battery shows nothing high 40% for cell standby and phone idle. Everything else (Facebook, etc.) REALLY low.
Then I went to Spare Parts > Battery Usage, Partial wake usage, everything incredibly low as well..
I will try Watchdog, but could it just be a bad battery? Or maybe should I try a different ROM?
Thanks!

NO! This is poor recommendation, and people need to stop perpetuating it. People keep recommending this, but its NOT a good idea to let the battery drain until it dies, just to calibrate the battery meter. While the protection circuit on the battery will USUALLY prevent over discharge, it is not 100% failsafe. There is a slight possibility that over-discharge of the battery will happen, and then the battery is no good, and will need to be replaced. Unless you have a special battery meter with a "boost" function (which most people do not have access to). See the following table on Battery University, where it says for Li ion batteries: Discharge: Prevent full cycles
http://batteryuniversity.com/learn/article/do_and_dont_battery_table
Best practice is to charge to 100%, drain to about 20%, repeat a couple times. No need to go below 20%. The battery meter is not very accurate to begin with, so there is no value added going to 0% versus 20%, but you risk killing the battery.
Plus people keep abusing the terminology. You are just calibrating the battery meter, not "calibrating the battery". When people say this, I think its just a holdover from the old days of NiCad batteries, where you had to condition/discharge the batteries periodically to prevent memory effects (Li ion batteries do not suffer from memory effects, and require no period cycling).
Can't really speak to the Atrix or the iPhone. But the battery drain on the DZ described by the OP is right in line with what I've seen. I also have an unlocked Bell DZ on AT&T, and battery drain of 2-4% (on various ROMs and couple different radios) when the phone is completely idle, screen off is totally normal. Best I've seen on my DZ is with the Virtuous Unity ROM and the .30 Gingerbread radio, where I've seen somewhere around 1-2% drain per hour when idle.
One possibility, is that the different phones are not reporting % battery the same way. As I've mentioned above, the battery voltage meters on phones is not very accurate, maybe in the range of 5-10% accuracy (although, even with this, the drain on the DZ versus the ATrix and iPhone still sounds inconsistent). But what is more important is how many hours of usage you get before needing to charge.
Thanks for the info.. Ill try charging that way.
And I honestly think the battery is just reading it wrong. It honestly feels like it dies faster idle than not, go figure. Yesterday, at like 10% battery, I wanted to kill it off, and played a game for like 10 minutes straight, still 10...
Then I tried leaving the flashlight on for 10 minutes on and it maybe lost 1
How is that battery I recommended from dealextreme though?
Sent from my HTC Desire Z using XDA Premium App
It's interesting to see all the troubles that people are getting on the DZ...
I've had my DZ for about 6months and never seen any of the reported problems.
My 1350mha will last me on a frequent usage near 24hrs and if I'm using it lightly like when i'm busy at work... almost 2days worth.
Mind you I'm running Cyanogen MOD7. No GPS. Wifi is on and I use JuiceDefender.
Cheers mates.
Last night, I charged my phone to a complete charge before going to bed to see what kind of drain I would see overnight. After 9.5 hours, my battery had only lost 2% sitting idle. That is with 3G on, but no Wifi or Bluetooth enabled.
The phone idle accounted for 47%, cell standby 48% and Android system 4%
While it seems remarkable, I'm still not convinced that its not my phone incorrectly reporting the battery level. On a typical day when I pull my phone off the charger, the first 10% is very slow to drain. Today, I have sent a few text messages and played maybe 3 minutes of word feud. That has drained 6% of my battery.
We will see where I'm at later in the day. I suspect that the actual level is lower than the 94% it is reporting. Typically, I get between 12-16 hours of usage, depending on how much I play with my phone.
Well I am at nearly 23 hours on this charge. Have used the phone rather lightly during the day. It sat idle for about 9 of those hours while I slept last night.
Conclusion: Idle drain is very minimal on my device and looks as though the percentage was being reported rather accurately. I'd say if you're having a lot of drain while sitting idle, do some digging and find what it is.

- I tried using greenify on everything i could think of.
Today i woke up to a phone that had a depleted its battery more or less overnight with just 30% screen on time.
I did experience the phone lasting 2½ days without a charge during my holidays and that was with 2 hrs screentime and 35% left. That's the kind of performance I'd wish for. The phone is rooted, and I'm using solo launcher, but hardly any customization that aside.
I took SCREENSHOTS of everything that might be important. Maybe you can tell me whats wrong. Under cpu states it says 1khz and only that. Isn't that a bit odd?

IMO that's not too bad I have a 7200 mah battery and it last me about that longs with around 4 hours of SOT, but it seems like your phone might be clocking too high, and brightness might be too high for the screen to be the main suspect like that, with only 30 mins of SOT
I think it's linked to the 3g/4g. If I disable that my phone will last significantly longer. I spend roughly 2 hours on transport a day. Conversely during my holidays it stayed in and around a summerhouse for 2½ days on one charge with 3g with long screen time and camera use. That's a hypothesis at least. Also I didn't use google music or any other audio player at that time.
I can get 2 hrs of SoT, but then I have to actively spend all the battery in the first half of the day, because after a full day the battery will be more or less drained regardless of SoT
If you don't ever use your printing features then i would delete those apps also because the printing service are usually turned on by default and searching for something to connect too or make sure its turned off in your ROMs settings so its not constantly searching.
90% of the time that unexplained battery drain occurs it is caused by low signal and the phone constantly trying to lock on or find a better signal. You can try to decrease this drain by using wifi in low signal areas but your phone will still drain your battery if the voice signal is low to. My phone lasts all day and then some when I'm in good signal coverage. When I go to my brother in law's house which is out in the middle of no where my phone will drain the battery in a matter of hours.
7% of battery overnight.
Wifi, 3G, google now and side clock on.
Is this normal?
Standby Cell=2% (5h on time)
Android OS =1% (13m cpu)
Standby Device = 1% (4m cpu, 28m active)
I too loose between 5-7% overnight (8 Hours). Although the battery life of Edge+ is pretty good while in use, I have noticed that standby of the device isn't as impressive as earlier Note variants (Yes, I'm comparing with Note series).
WiFi - ON
Auto Sync - ON
2-3 Apps with Notification ON
Samsung Pay on Screen Off - ON

Your CPU seems to be idle 95% of the time! I never checked mine but yes, mine drops that much too! I don't think that's a rare case with this phone!
Ok so it is good right?
Then why it drains so much overnight?
Depinding on my signal strenght ,i saw -10% overnight ,ok maybe i slept like 10 hrs insted of 7-8 but still . Battery info said that the juice went to Cell signal standby or something like that.

yep, same here... so maybe it depends on the strength and quality of cell signal..
will test in the next days...
I am sure it cannot be any samsung app/service as I have disable 200 of them with package disabler pro
also, location/3g/wifi/sync/googlenow always on is the same setup I had on OnePlus One, that was using barely .5% per hour
it also true that on the OnePlusOne I could also turn off the notification light during night, while with this I cannot so it could happen that the light keeps on flashing for 5 hours, draining battery
also, I have edge clock on at night, still some drining...
I thought the deep sleep or idle drain was caused by lollipop, no? I lose over 10% from a 7hr sleep, even if I turn the WiFi off. WiFi eats up a lot of my battery for some reason, and I know my connection was good too.

It's been 5 nights and I confirm it drains 1% per hour.
This is my usage really bad...
8% in 6h
Night clock on
Wi-Fi on
4G on
Sync on
I received 5 emails so notification light has been blinking for almost 5h
Don't understand, cos stats are not that bad...
Think yourself lucky. I'm losing 50% overnight.
Battery life impressive during the day though

I solved my problem: night watch...
With night watch on I lose 1% per hour at night, with night watch off I lose 2% in 6h
I was consistently losing 2%-3% per hour overnight. But once I found an overactive app (Plume) and changed from instant notifications to 30 minute polling, my battery life has drastically improved. I've also used Package Disabler to disable bloatware on my device.
The past couple days my battery has been around 97% - 98% when I wake up in the morning.
