Poor Battery Performance

I have had my Galaxy S for a bit over a week now and am pretty disappointed with the battery performance. Most days I take my battery off the charger at 7am and it reaches 15% low battery warning by 1-2pm. I do spend a fair amount of time reading XDA and listening to music. I'm currently running Stock JM1 firmware with no lagfixes.
Here's a list of my apps that I have installed:
http://www.appbrain.com/user/Lokhor/apps-on-the-samsung-galaxy-s
I am running JuiceDefender which I thought would make a big difference and does not. I have also set Tasker to change the Brightness level to 20 (below the safety threshold) when the battery reaches 50% or below, otherwise the brightness is at the minimum (30%).
I have heard that you need to condition the battery so I have been trying to do this but it doesn't seem to have had much effect. Today I used my phone only casually and it's currently at 22% after 12.5 hours. The battery use details show the following:
Display at 56% being on for 2h22m and 13s.
Cell Standby 18% Time on 9h21m, time without signal 13%
Phone Idle 7% Time on 7h33m
Android System 5% CPU usage 23m39s CPU foreground 24s
Android OS 3% CPU Usage 13m 27s
Is this normal? Is there anything I'm doing wrong?
Please help

I don't know what others are telling you about conditioning a LiIon battery but you don't have to. LiIon batteries don't suffer from what NiCad do. Some do suggest wearing the battery down to nil and then charging it up again. However, this is pretty bad for the battery and should not be done more than once every 30 cycles. With every LiIon battery I've ever owned I've either trickle charged it or charged it when it wasn't too low and they've all lasted over 3 years. I've never conditioned one.
Anyway, my advice to you is to see how long your battery lasts in standby. Mine could probably last 3 days or more if I don't bother it too much (with sync, wifi and all that good stuff). I find the worst contender for battery drain is the display. The only problem I see with your stats there is that I've played Asphalt5 for around an hour and a half which is quite heavy on juice and it only drains roughly 10%-15%. Then again you're browsing the web so maybe probably worse.

Oh, and when charging your phone, don't use the USB hooked up to a computer as it doesn't stop charging when it's full. Use the wall charger to charge.

I found that charging it whenever it was convenient instead of when it was low would result in a charge that lasted ~24 hours.
I've noticed significant increase in battery life since I started waiting for the 15% charge warning, plugging it in till it was full and then unplugging it. I get 2-3 days of use this way.
I also set my email to only sync between 6 AM and 11 PM. I believe this helps a lot as well.

since we are about this topic, check this out
How to spot fake battery vs. OEM battery: http://forum.xda-developers.com/showthread.php?p=7953322

so if I'm listening to music during the day at work should I have my phone plugged into the wall charger or just let the battery run down?
Last night I took the charger off at midnight when it was full and when I woke up it had only dropped 5%. After reading my emails quickly it was at 93%.

it works fine either way

I find leaving the brightness on automatic uses up loads of battery. Setting it to lowest seems to make the phone last 24hrs+
I also found that having beautiful widgets clock/weather installed used up a lot of battery for some reason.

I don't use weather because it has to sync every so often to update it which to me is a waste...I'll just look outside. I also leave brightness on the lowest setting wherever I am as the screen is already very bright (why waste battery?).

My experiences with my SGS have taught me to be conservative with its battery. Anytime you turn the screen on, you eat power like crazy. The best bet is to just top her off whenever the need arises. Personally, I have found that I'm fine just topping her off in the car when I'm driving, so that I start my work day at high 90's, and especially once I've got my morning browsing out of the way, I don't eat a big chunk of battery at any other time.
But yes, if you find you are running low, you can happily just take a half hour to charge from a USB port to give you an extra boost. Alternatively, spare batteries and so forth do the same thing, although it can be annoying if you don't have a charger that will do the phone and a spare battery at once.

im experimenting with apndroid now to turn of 3g then i dont specifacly need it. It comes with an on/off widget. Looks promising so far. 40% at 2300 hour and then i have used wifi a bit, played angry birds and talked for about 2 hours in total.

[Q] 4 hour battery life on heavy non gaming usage

i am getting 4 hours tops of batterylife on my z1
i have maximum brightness auto turned off i have wifi and bluetooth off
i have a live wallpaper
i have skype steam running in the back
it takes 2 hours for it to drop to 50 and 4 hours to 0 from full charge on pretty much full on screen time
is this normal even on that kind of heavy usage

I would recommend using wakelock detector to see what's really soaking up your battery. It's a free application and it's pretty self explanatory. Charge up your phone and use it heavily again and report back to us with your findings through wake lock detector.
Sent from my Nexus 7 using xda app-developers app

Have push mail on ? My phone was empty very quick before the update .257 but now its much better.
I think if you mean with 4 hours onscreen it is normal otherwise it is not.
Use wakelock detector already mentioned

4 hours on screen time with full brightness sounds reasonable. I can play heavy games for about 3,5 to 4 hours with medium display brightness.
Always keep in mind that the display is the biggest power consumer in modern Smartphones.

so the battery really is that bad?
using stamina it drops 20 or so % during the night

Actually the battery with its 3000 mAh is gigantic. And I think 4 Hours of heavy usage with full brightness is ok.
20% over night with STAMINA mode is too much though.

i have steam and skype whitlisted in stamina
really dissapointed in the battery life then
i guess theres no such thing as a full day of usage then
is there any smartphone that can handle that?

Do you actively use your phone all day (screen on all the time)?
With medium usage (WhatsApp, Surfing, Some calls) I can go for at least one, maybe two days.

I slept for 10 hours and my battery drained 9% with wifi and GSM on from full charge. your using the stock charger right? charging faster then recommended will reduce the life of the battery and can cause this kind of issue, but the phone is so new i wouldn't expect that to be the cause. I know the stock charger 1.5A. With a 2A charger it is likely the phone will charge at 2A.
Its probably a software related issue your having, but 20% overnight seems like a lot..

I would something is hitting your phone for wakelocks. 20% over night is a bit high. I know google currents is a know offender so uncheck that if you have it syncing. Try turning off google location access. Turn off gps and nfc. Using you phone at max brightness will always be very draining, leave on on auto unless your outside in daylight or in the car. Facebook is also bad for wakelocks. Any app that is polling for updates will be hard on battery. My experience has been a much improved battery life over my previous devices. On an average work day I leave at 8 and get home at 430, and I usually have 70-75 % by bedtime usually around 30%. I leave most my apps syncing all the time as well. I know the phone is new to you so I would say you might be playing with it more than you normally would.

I suspect that steam / skype will be preventing the phone from ever going to sleep.
I would suggest capping the max frequency of the cpu to quite slow or setting the governer to a conservative level (an app could be forcing the cpu to stay at a high frequency most of the time which will just drain the battery in no time)
However this usually requires a custom kernal or at least root which isn't very well developed on the Z1 yet.
If you can run a wakelock program that also logs the time spent at each cpu speed ... that would help people help you ...
As for any phone being able to handle it, unlikely the battery is relatively large but so is the screen, most phablets have only a fractionally bigger battery.
Only a full blown tablet will get you a much bigger battery that might be able to last you twice as long.
I typically go 3-4 days between charges on the .257 firmware without stamina mode and paired to a smartwatch 2.
I used to get 3 days on the 534 firmware with stamina mode! (i work in an area of very weak signal so i get 25% no signal time over a battery charge)

Normal Battery drain or defective Turbo?

So I've had my phone a little over a month now and i never got amazing battery life, but compared to other phones it was solid. However, i see people with 6-7 hours of screen on time, when i struggle to squeeze 4 out of my phone. Typically i get down to about 10% with 17 hours total and 3.5 hours of screen on time. Also my phone usually turns off at 5-10% randomly, is this normal? Lastly, every so often if i let the battery run down until it turns off (8% or so) i get a screen that shows the battery sign with an exclamation mark on the inside. Is my phone defective or are peoples battery stats a matter of difference in usage.

SOT heavily depends on use and screen brightness.
I always get 6-7, auto brightness, no gaming.

Yes but I'm saying i get a max of 4 hours SOT with absolutely no gaming. All i do is text and use normal stuff like twitter and instagram.

My device at the same, up to 5 SOT
Do you think battery problems on this device?
Edit: 8-10 hours standby -> %10 battery drain...
Location - Battery saving(always)
Brightness - Auto(always)
Wifi - off(idle off- Scanning always available <-OFF)
Network - 2G(idle)
Bloatware - all disabled
Moto Apps - Only Moto Display -ON-
Facebook / Twitter - I don't use!

I typically see 1% battery drain for every hour in stand by and 10% for every hour of screen on time. After 24 hours with 2 hrs SOT, I'll be around 55%. I don't use WiFi or GPS very often.

Just wait for Lollipop update and the excessive battery drain will be gone. With KitKat I had around 10% or more battery drain overnight, but now I'm having at most 1%-2% with the same synced settings, so it was a huge improve, believe me.
Besides this, try to disable Moto Actions (except camera wrist), keep those sensors awake all the time drain a lot of battery. The exclamation sign inside the battery should be present in around 5% battery left.
Also, as far as I know, Turbo will be updated directly to 5.1, so it would be better, but hope that Verizon crap-ware doesn’t ruin the update.

Is this normal battery behavior?

So taking a look at my screenshot after a long 14 hour work day I'm down to 35% yet with only 1.44hr of OST. I've seen numerous reports about 5/6/7 hours OST but the most I've gotten was 5 hours and change with the battery all the way down to no more than 10% and that's with battery saver automatically activated at 20%. I do not have force 90hz on anymore for the past week and I'm currently rooted in December patch stock kernel and minimal magisk modules installed. Running substratum of course and Viper. Nothing else really fancy going in with my setup. Been eyeing down better battery stats and nothing is hogging battery consumption in the background. Any thoughts on this would be very much appreciated. And yes I'm aware of the disappointing battery size but I believe I should still be seeing much better performance than this.

It's normal for a device with a small battery. Check if you have any wakelocks and start carying a portable charger

Do you have the P4 XL?
I'm on force 90 hz, mobile network all day, 90% brightness level, rooted with magisk, only thing I'm not using is motion sense (not available in my country and don't want to force it with any module yet) and get 6-7 hours SOT easily

You "Full charge lasts about" is still a decent 19 hour and 15 minutes so do you always end around 35% and under 2 hours SOT? Do you stream something with the screen off most the day?

I'm always checking for walelocks and I have nothing abnormal going in there and I even have a dozen apps battery restricted

FFS, don't believe the stupid train on SOT being a remotely valid indicator of a device's battery life. your SOT will never match the next person's nor will it be a reliable indicator that you'll get that amount the next day. you should be measuring your battery drain rate and determining what's causing your battery to get eaten up through the day.

I do agree that SoT is not a good indicator. For starters, a device with a screen at 100% brightness doing the same workload as a device with a screen at 50% brightness will have wildly different SoT. The SoT is only perhaps relevant to you individually, and only after a long time of use when enough data was gathered for you to know the actual average SoT.

I mean my full charge lasts about 16 hours, but yet some days get 7 hours sot and others 3, it's all in how you use it. I'm still stock and haven't rooted.

General Screen on Time (SOT) - Note 10 Pro Max

I am at over 9 hours SOT with more than 10% battery intact yet.
Mostly run at 60Hz, a fair trade off for that kinda SOT.

Mine was similar 9 hours and a half , but with 120hz
Wifi, data, bluetooth on, auto lighting, and was only consuming social media and youtube that day

That is incredibly good. I haven't gotten that kinda SOT with 120hz y let. My phone's continuously connected with a smartwatch as well. But even at 60Hz, the trade off is fair enough.

Can't say it's farily good...theoretically it should give more than 10 hrs at 60 Hz.

It all depends on the use, and the time you use it, for example, if you use it nonstop with social media with a 100% cycle charge, I think with 60hz it would last 10 hours minimum, but if you use it, let's say, 3 screen hours a day, your battery will be over in day two with 6 SOT, becasue the standby drains aswell

I agree, but at the end what matters is reasonably good SOT overall and no idle battery drain. If these two are ok, everyone will be happy.

I just got 5-6 hours SOT, i dont know what cause it. Maybe you can share tips how to get long SOT on redmi note 10 pro? Thanks before

BB belongs to personal use.
I i am more kinda light user and i have about 3 hrs SOT but 3 one charge is enought for me to run the phone for 3 days

Idle Battery Drain: 1-6% for 7hrs night (observed only once)
(Sorry the SS is dull and dim because I had enabled the option "Adjust text and background automatically" in Display settings, turning OFF later fixed SS)

This phone is dha bomb! Crosses 9hr SOT easy with 120Hz on with 5-7% still left.
P.S: AOD turned off, don't like that feature until LTPO displays are the norm anyways.

Hi everyone.
7h 30m on 120hz
2+ days of comfy, normal use, with high brightness, etc.
(Pixel Experience, will test on 60hz next)

I get a max of 3 hours sot with 120hz and a 80% of battery in the morning. After 2 hours and 45 minutes of screen i have 20% left

8h 45m
120 mHz, light theme, mostly high brightness. Pixel Exp.
