Okay so I noticed my Captivate seems to lose a lot of battery while in standby. To test this, I left it unplugged when I went to bed last night. I checked the battery level right when I went to sleep and then again when I woke up...
My battery drained from 64% to 31% in about 7 hours!!!
I know other threads discuss bad battery life. A bright screen and a 1GHZ processor can cause this so I can understand why the phone won't allow me to browse the web for 10 hours straight. But is everyone else getting an almost 5%/hour drain in battery while in standby?
Here is a little info about my setup:
-I took off an animated background and put one that is relatively dark (Screen is off during standby so I would think this doesn't matter)
-I have WiFi and Bluetooth enabled.
-I use both wireless networks and GPS for location.
-I have 1 Gmail account setup to check every hour.
-I have the Daily Briefing set up to check every 3 hours.
-I have the Slickdeals widget set to check every 2 hours.
-I have the Latitude widget running (you can't set how often it refreshes).
-I have the ESPN ScoreCenter widget running.
That's about all I did that I can think of that can possibly affect battery. I know I would get better battery with less background widgets, but all of this is in line with the amount of background services I had running on my last phone (Tilt 2) and that thing would last for several days with light use.
So, what I'm trying to find out is whether or not this is normal behavior that everyone is seeing or perhaps if one of the background widgets I'm using is known for draining a crazy amount of battery. Maybe I need to hard reset the phone? Thanks in advance for any ideas on how to lock this down.
In poor reception I could see that. But I'm good area that's too much. Like 2% every hour is good... 5 is too much....
Thanks for your reply. I had 3 bars of service where I was last night. Also, this isn't the first time I've noticed about 5%/hour for standby, just one example...
So it sounds like I'm getting worse drain than normal? Now, how to fix it?
Well...with all the email checks and having various Widgets check for updates..it will definitely drain the battery. I have been able to easily get twelve+ hours on standby without GPS on and turning off wifi when not at home or in a place with wifi.
Definitely can't go days without charging like I could with previous phones like my blackjack II buy I can get 12-16 hours with light to moderate use and 10-12 with somewhat moderate use of Facebook, wifi, various other apps.
EDIT: the Bluetooth as well will drain the battery.

I have very similar battery usage to use. About 5% an hour not doing anything. I am always around a wifi and leave it turned on. I have nearly an out of the box setup. Between the poor battery life and crappy GPS, I may very well be taking this thing back.
Under Settings > Wireless and Network > Wi-Fi settings > Bring up the Advanced menu and set the Wi-Fi sleep policy to "Never".
This has helped my battery life immensely, since I am around Wi-Fi most of the time. This way all your data happens over Wi-Fi instead of 3G when the screen sleeps. I disable Wi-Fi when I'm not around any APs I normally connect to.
Pulled phone off the charger at 6:00AM yesterday morning. Streamed an hour and half to 2+ hours worth of Pandora over wi-fi getting ready for work and then some in the car. Did some web surfing during the day, various other things. (No phone calls really, except a brief wrong number). 4 e-mail accounts checking every 30 minutes (one an Exchange server). Also have Touchdown running push e-mail for another Exchange mailbox along with the Touchdown widget. Played around with some GPS apps (new google maps, Places, etc for a few minutes). Battery was down to about 16% by about midnight last night.
My phone charged fully overnight (with power off). Was turned on at 7AM, it is now 11am, and am at 90%.
I do not use GPS, have nothing running, no emails or social networking status updates.. The phone is on standby on my desk. I only do a few text messages and 5 minutes of voice calls / day.
So this means I get 40hrs of standby time? That is a little ridiculous.
I chatted with AT&T tech support and they said that the AT&T stores don't have battery replacements yet, but I could get a full phone replacement since I am within the 30 days still.
But from what I am hearing, it seems most people are having the same issue if not worse, correct?
I really don't want to set everything back up AGAIN. I am coming from using a Samsung Eternity - understand it isn't a true "smartphone" - but I use it the same, and would easily go 3-4 days without needing a charge.
with GPS off, wifi off, BT off, no data sync or background data turned on, i charge it fully at night -
last 3 nights in a row, at midnight it was showing 100% and at 7:30AM it would show 97-98% remaining, and that was using the alarm, set to loud and probably ran 2 minutes before i'd hit the off button
From 7:30am-11am, I have used 4% of my battery. I have these things going on:
-Exchange sync (real time)
-Facebook sync (once every hour)
-wireless off, bluetooth off, GPS not being utilized
-Weather.com and a Google search widget
The battery use shows this:
-Cell standby: 48%
-Phone idle: 36%
-Display: 8%
-Android System: 3%
-Email: 3%
-Android OS: 2%
I've barely used my phone this morning, so I'd think 4% of use in 3.5 hours is quite acceptable. It sounds like you need to make some modifications to improve your performance.
firehazard - what modifications have you done? I have wifi/bt off, background data off, no email syncing - display brightness all the way down..
To anyone who is having very poor battery life, I suggest a factory data reset when you exhaust other options. My phone wasn't lasting me more than about 8 hours on a full charge, with light to moderate usage. After a factory reset, I just ran nearly 24 hours with similar usage.
I can't tell you what changed or what got removed, maybe it was an app that was running and draining the battery that I didn't see, but battery life is MUCH better now. Hell, everything is running much better, even the GPS.
I went from wanting to throw this phone at a wall and return it for my iPhone 4 again, to loving it in less than 24 hours.

I'm referring to him running wifi and bluetooth when he's not even using his phone. Stuff like that.
Just for recording keeping, when a phone company says their phone can last XXXHours in Standby this means, that all wireless transmitters are off. this means (for the most part) airplane mode, with bluetooth, and wifi OFF.
these continuous wireless transmitters are why you didnt get the 200Hours or what ever it is in standby mode.
I recently took my phone back to BestBuy for a replacement since my battery was trying to kill itself overnight as well. I did the full charge when I first got it and purposely ran the battery down to quickly get it to turn itself off at 0%. Did a full recharge and repeated this process about 3 times and last night my battery only went down 3% over 6 hours. Compared to the 30-40% that was draining before, I'd say the full discharge/full recharge works that people have been talking about in the battery threads works. Thanks, everyone! I use Y5 to have it automatically connect to my WiFi at home when it's in range. Not much more than the usual was left to sync (although JuiceDefender may be working to turn stuff off when my screen is off) such as Gmail, Beautiful widgets, facebook, and one rss feed.
Either that or I had a crappy battery before
Seems like some folks are having the same problem as me, while others are having much better results. Firehazard's situation and drain while not in use is pretty much in line with my expectations of the phone. With my old Tilt 2, I left WiFi and Bluetooth on all the time and still got great standby time out of the phone. When those connections weren't in use, they weren't really draining my battery in any way. I'm going to try to disable them though and see if that helps. I'll also try to monitor the battery usage screen and see how much power is going to wifi and bluetooth when I have them on.
I've been suspicious of my battery as well, tracking it casually today.
Took it off the charger approx 8:30am, immediately went to 99%.
Watching it over the last hour it appears to be losing 1% / 10 minutes.

Just using it for the past 5 minutes to write up everything running has dropped the battery almost 3%. Albeit I have terrible cell coverage where I am. It does seem that the cell and wifi receivers are a bit weak, or the meters are biased conservatively.
*edit* I want to be clear that I love this phone, I just want to try and find out what and if certain services/applications drain the battery and if not then if I have a bad battery.
Okay, so I turned OFF bluetooth and WiFi and checked the battery before bed and right when I woke up. This time, I lost 24% over 8 hours. Certainly a big improvement over 33% in 7 hours, but also no where near where my old Tilt 2 was. I would lose 2-3% overnight at the most with that phone. I checked the battery meter and the majority of the battery went to Cell Standby and Phone Idle. Those don't seem like things that can be avoided through tweaking. I was in an area with 3 bars of service (same as night before), so I don't think that was an issue.
I'm debating whether or not I should try a factory data reset. Some folks reported good results with that. I really don't feel like reconfiguring my whole device if there isn't a good chance for improvement. Maybe the GPS fix that's coming will help battery life?
Have you tried reconditioning the battery? That would be the charging/discharching cycles mentioned throughout the forum?
I have done it and my phone has been on standby for more than 24 hours and I am still at 50% battery. It's just had very light usage. Wifi on for about an hour, snapping a few pics, deleting some others. A bit of calc usage. When I first got it, my battery was dismal.
Mine hasn't been modded one bit yet, just installed some apps from the market and a weather widget.
Yes, tried that. It actually helped a little but I'm still getting poor results compared to some.
I have another theory/question. I use gmail as my only email account on my phone. Its set up through the system and it syncs to the gmail application on the phone. I also have it set up in the Samsung default email client (which I prefer). Am I wasting battery because the two apps are checking mail independently? Does the gmail account sync while the Samsung one checks at intervals (I have mine set to 1 hr)?

probably.
follow battery optimization guide in pimp my captivate.pdf thread. I get 1-2% battery consumption per hour with moderate to light usage.
heavy usage drops my battery about 4-5% per hour. By heavy usage I mean playing 3D games for hours str8
Hi Friends,
While HTC EVO 3D fellows looking for tips how to increase battery time here in the link
http://forum.xda-developers.com/showthread.php?t=1141221
I decided and checked my own LG-3D P920 . here are results (after 100% charged with adopter.)
Before test , i made sure followings
1 - 2G Data set to enabled all times
2 - GMail Sync Set and receives and send emails As soon as arrive
3 - Facebook account set
4 - Hotmail Account set to sync as push mail.
so all above done to use 2G non-stop. Now what I did with phone during test time
Made 30 minutes phone calls
15 SMS Received
10 SMS Sent
30 Minutes browsing & email reading
05 3D pictures captured
02 2D pictures captured
Viewing the pictures new and older ones- 10 minutes
Watched 10 minutes 3D pre-installed clips at phone
Played with phone ,like phone settings , check battery status several times - 10 minutes
Now phone is still alive after 65 hrs. still 8% battery remaining but going to charge to avoid any problem.
So what you think now, which worth more ? white elephant or black horse ???
Please don't forget to share your experience with Battery Time.
8% left after 65 hours is not so bad. I get two or maybe two and a half days and I don't take much photos, send/receive SMS or watch 3D content.
The only thing my LG is doing at the moment is syncing gmail, calendar and contacts as well as hotmail push. But over 3G, not 2G. Right now it's at 57% after 20 hours.
I'm using TiaiZO3D 1.5.1 and I removed the stock LG Home completely and replaced it with ADW Launcher. That seems to reduce battery usage a little bit (at least in Standby).
I never use WiFi and GPS only rarely. Screen is set to Auto Brightness.
65 hours its nice, i have this phone like 5 days now and my battery no longer last 16-20 hours with mid use. im gonna check the link and post my results.

Please let us know your final result..
btw , i dont want to take risk to install customized stuff at 1 week older phone...
I think , Launcher pro will increase the battery time but I wanted to test with default.
One thing i noticed:
In my Battery Usage statistics there used to be that entry "Android System" always hangin around 70%
Since I removed the LG Home Launcher for good and started using ADW Launcher, Android System floats around 10%
And I really have the impression that battery life increased slightly by switching launchers.
On 10k my android system is around 5% before it was in the high 70's.
my media server is at 50+% all the time and my battery runs out really fast. i get 30mins of hd video on balance mode and if i choose save battery mode the video stutters when playing hd videos (so it gets annoying to watch). does anyone have this problem or have a solution to sort it out?
on max setting while playing dead trigger 2 i get 1% a min of battery usuage
on balance setting i get hd video + wifi + 0 brightness + 0 volume 30mins per 10% of battery (same with browsing web)
on saving i get 40ish mins per 10% of battery while browsing web
my media server is always 50+% even after i turned off all sync uninstalled apps and even after factory reset
i got a tegra note 7
I'm in HAVOC 2.0 OFFICIAL (Pie), but it will work with ANY custom rom. If you don't have the 1st option Smart Pixels in "Havoc Settings" ('cause you're using another Custom Rom) you can use the app: "Pixoff: Battery Saver" or similar...
Tutorial>>>>>
1 - Havoc Settings > Screen > Turn on Smart Pixels (62% of pixels disabled), and increase the brightness just a little to compensate.
2 - Use Greenify along with Greenify4Magisk module to freeze all GCM apps.. But you can just disable GCM and other stuff in "MyAndroidTools Pro" by yourself decreasing the need of freezing unnecessary apps... but you have to understand how android works or you will break your system (USE WITH CAUTION). (A 1 million dollar tip here: Disable things like "analytics", "gms", "GCM" (if you're not finding those words tick this icon "<-->" to expand the service names..
P.S.: Only play with Third Party apps... Don't mess with system apps!
3 - Use Naptime to make Doze mode work properly...
4 - Use AfWall+ to block all apps that don't use internet to leak data and hog your battery unnecessarily.
Extra Magisk modules I'm using:
- AdGuardDNS Adblocker (unofficial)
- Sysconfig Patcher (sp) helps to doze Google Play Services and system apps that hogs battery...
- Swap Torpedo -> to SPEED memory.. my old devices 1gb ram runs blazing fast with this and it works so f**cking good in Note 5 aswell..
* You can turn all animations off systemwide and your experience will be better IMHO
You can tell me if it worked or not.. But I'm getting 14hours of SCREEN ON TIME. :victory::laugh:
In the screenshot below I was in 7h39mins of Screen On Time with 50%... I'm just sharing all these stuff 'cause I finally manage to have a GREAT battery life. I used to mess with Amplify app once and didn't have so good experiences (Phone app missing calls and whatsapp doesn't showing notifications), but maybe someone else manage to get a better SOT than mine, using it properly..

Nice share
But usually the SOT is not the similar that you would get from 100 to 50 % battery and from 50 to 0 % battery. So it's not fair to say the SOT would double by sharing a screenshot of 100 to 50 % of usage.

If my usage will keep the same (4G always on: Whatsapp + Opera (facebook site mainly) + Instagram + editing photos on Snapseed + gallery), my estimated SOT is 12-14 hours.. I will post a new 100% test screenshot to prove you.
I mean, if the mAh consumption will keep the same over the same kind of usage, it's easy to trace a statistic number over it. Ok ok.. You want proof, just test it and tell me.. I had to plug the phone in PC to install some last apks.. But tonight was my final installs and tomorrow I will test it from 100% to almost 0%
Getting 11 hours of SOT on Revolution OS & Insigniux kernel and no tweaks at all. My usage consists of a lot of YouTube, reading books on the Kindle app, playing some games, and the usual social media (whatsapp, twitter, instagram). I also listen to a lot of music via bluetooth headset (about 5 hours per day). The phone lasts almost 2 days with such a usage. So yeah, I think this is more than enough for the average user such as myself, no need for all the hassle you posted above. It's really unnecessary.At this point, this is just turning to a "who has the best SOT" battle. Even 7/8 hours of SOT is something great for this device, while 800/1000$ flagships are struggling to push over 5 hours of SOT.
Thanks a lot for the time spent writing this. Would you have more information about the firmware and kernel you're using ?
First, to everyone that read OP, realize there are some inaccuracies. Sorry man.
Smart pixel settings and apps like PixOff only save battery for OLED displays. HAVOK OS is available for multiple devices and this feature is beneficial for devices with OLED displays, but does not make a difference to LCDs.
Our phone has an LCD display which cannot actually "turn off" a pixel . It consumes the same amount of battery no matter what color it displays. Display brightness makes the biggest difference in display battery consumption.
So by turning on "smart pixel" and increasing the brightness you are actually HURTING your battery life overall.
Secondly, you only tested from 100-50%. You will ALWAYS get vastly more battery life from the top 50% than the bottom, because batteries voltage does not drop linearly, it is chemical reaction that is actually quite hard to measure accurately.
There have been many times where I was "getting 14-15 hours SOT" in the top half, but then watch as your battery drops from 40-20 from only 1 hour of light use. I can almost promise you this guy won't actually get more than 11 hours by the time he hits 0.
Use it from 100-0 at least 10 times , showing 13-14 hours of SOT and I will actually believe you are on to something.
On MiUI 9.5.17.0 I already can achieve close to 14 hours SOT, but that is within 1 day 10 hours usage. Usually I get 11-13 hours only within 1+ day usage. On AOSP, specificly RR 6.2.0, I easily reach 4-5 hours SOT by 70% (which I usually charge it already), 15 hours if interpolated to 2 days usage. 10 hours SOT is almost guaranteed. Last test is 13 hours SOT within 2 days 2 hours. If you want to see what is the configuration and usage, just check the link. I prefer to state my configuration and usage during the test, to show any possible different variable.
1. SmartPixel AFAIK is useless in IPS LCD. I would prefer the full maximum resolution as not to downgrade my user experience
2. I don't use any greenify, simply use the battery optimization from android. I whitelist several apps : Automagic, GMD gesture, Whatsapp, MiXplorer. I never clean my recent/RAM. I remove the "nuke button" from the configuration.
4. I don't know starting from which version, but since Nougat 7.0+, we have the setting to restrict data usage for each app in the app info. I simply create a flow to automagically open the app info everytime I install new app and decide whether to restrict the internet usage or not.
For ads, I just use hosts based - adaway. I don't limit play services, just let it run normally. I don't tweak much on the RAM side, but I adjust the minfree on every reboot (using automagic) to the lower value than default by RR. This is to let more apps stay on RAM as long as possible.
I don't want to limit the phone's perfomance to ridiculous level. Smartphone are meant to be used. The battery used is the proof we enjoy technology. Of course if the drain is unusual and wasted, we have to troubleshoot and find the culprit, as I have done in the wifi deep sleep drain bug. But other than those exception, I want the full user experience I can get from my phone.
SOT Variation
SOT is kinda non standard way to measure the usage. It varies depends on the user habit and usage behaviour. I am using dual SIM with good signal in most of the time, no microsd. Common usage :
- idle with no internet : 0,3-0,4%/hour
- idle with wifi : 0,5%/hour
- idle with LTE : 0,6-0,7%/hour
- Screen on dim (brightness < 10%) : 5%/hour (outside of idle drain)
- screen on bright (brighntess > 80%) : 10%/hour (outside of idle drain)
- Play game : Depends on game, it can consume 8-20%/hour
Using basic math, If 25% are used for the idle with wifi, I can get 25% / 0,5%/hour = 50 hours usage. 75% for screen dimmed, I can get 75% / 5%/hour = 15 hours. So 15 hours SOT is possible within 2 days usage. This interpolate nicely with my 70% 4-5 hours SOT.
But If I use the phone outdoor and the brightness increase, I can only get half of that, 7,5 hours SOT only within the same 2 days. Or maybe 9 hours SOT within 20 hours usage. If I have bad signal, it will reduce even further, 5-6 hours SOT only. Playing heavy game (PUBG) usually reduce the SOT by half too. So playing PUBG in dimmed brightness will consume 10%/hour and in brighter, 20%/hour. Increasing/decreasing the graphic also modify the drain per hour. Usually playing heavy game result in max 5-7 hours SOT only. But sometimes I can still get projected SOT around 10 hours, depends on what game I play and how many hours I played it.
Taking it to the extreme, we can spare 10% for the wifi idle, giving 20 hours usage and 90% for screen, giving 18 hours SOT. Which mean we can achieve 18 hours SOT within 20 hours usage. I am quite addicted to the phone. I use it for browsing, learning language, reading ebook, watching video, designing flow in automagic, usually without any gaming. But even then, it is very difficult to use the phone straight for 18 hours within those 20 hours (without gaming).
It is very difficult for me in usual daily activity to test the battery life till 1%. I usually have to plugged the phone for screen mirroring or transfer data. It will skew the battery usage then. I also usually just charge the phone at around 60-70, sometimes higher, sometimes lower.
At this kind of battery life and perfomance (SD636), I am very happy with current usage without the need to tweak so much again. Just use your phone as usual and only troubleshoot the battery life if something drain too much without doing anything useful. Enjoy your smartphone.
Hello,
I just noticed that my phone has been using 14% battery in the last 3 hours. It was at 100% before. Battery usage shows that 3% have been used by the ambient display (used 2hrs, 28mins), 2% by the screen (11mins) and 1% by phone idle (2hrs 54mins). Thats 6%. The normal battery usage without the "Show full device usage" option shows 3% ambient display as well and 2% Phone (used 16mins).
Why am I missing 14% of my battery then? What could be the issue? I factory reset the phone last night, I have closed all apps and I have only installed 7 apps (Instagram, Whatsapp, Outlook, TuneIn Radio, Steam, Twitch and my banking app)
