I just got the Captivate on Sunday so maybe it needs some time to settle in or whatnot, but I thought I'd make a post about its battery life. How's everyones experience with the battery so far? I love this phone to death, but it seems like the battery life sucks so far. It also seems to take a really really long time to charge up.
I have the display at 11% and haven't done anything with the phone at all today and I'm already at 80%.
3h 12m since unplugged. Says what's using my battery is:
Display: 35%
Cell Standby: 22%
Phone Idle: 15%
Bezier - Live Wallpaper: 7%
Android System: 6%
Advanced Taskkiller Free: 5%
Alarm Clock Plus: 4%
Android OS: 3%
I have GPS, Wifi, Bluetooth all off. Autobrightness is off, I just have it set to 11%.
80% after 3 hours of doing absolutely nothing to the phone doesn't seem right. I'm killing apps I'm not using and the only thing more I could really do is kill the live wall paper but it doesn't seem to be taking that much battery life and I really like it.
Any thoughts?
Also it seems to take like an hour and a half to get like 15% charge when plugged into an outlet. It just takes absolutely forever to charge it.
Yea my battery life is also draining really fast. It tells me that the screen is using 73% of the battery though....
Any thoughts?

When I first got it I used it till it died pretty much and then charged it all the way back to full. Wasn't sure if this was necessary or not, but I'm just pointing out that I did it. I have obviously been using it a bunch when I first got it, but now I'm not, trying to see what kind of battery life I have. I haven't done anything except look at the phone a couple times this morning. Haven't even run an app.
Yea same here. Im doing the exact Same thing. I unplugged at like 8am and right now im at 80%

I unplugged my phone about 3 hours ago and I am at 93% battery life.
I am using Juice Defender, and I kill all apps that I don't want open.
I actually think this phone has great battery life. It typically takes a few charge cycles for the battery to settle in. I abuse the phone a lot and it lasts all day for me. Compared to my tilt2 this thing has much better battery. I would suggest that you guys run the battery all the way down, and let it charge fully overnight a few days in a row, and you should see and increase in performance.
Current Battery: 74% Unplugged for 5hrs 14 minutes
Display: 41%
voice calls: 37%
standby:11%
Idle:7%
android system: 3%

I just installed juicedefender. Looks interesting. We'll see if it makes a difference.
Running down the battery to about 5 or 10 percent and then charging all the way up several times definitely helps. Its been almost eleven hrs since I unplugged and I'm at 73%
Let it run down and then charge all the way up several times. Worked with my phone.

My Battery Life on my bold was better but then it is a different phone and the battery was almost 2 years old but still worked great. Now my battery is at 22% and when I left a 8:50 am PDT, I pulled it off of charge, and I am playing music to intentionally get the battery down to 5% or less before I charge it. Not bad considering, I am constantly doing a ton of stuff, browsing, playing games, playing music the first time, and running google earth/maps as well as you tube videos.
Cheers,
Charlie
ive been unplugged for 2 hours and 27 minutes and im down to 67%
Haven't done much with the phone all day. Installed juicedefender. Left it on easy settings. Not sure how much it's helping so far, if anything. This is my current breakdown: 8h, 48m since unplugged... 35% battery remaining. Display: 45%, cell standby: 16%, phone idle: 10%, Live Wallpaper: 7%, android system: 5%, beautiful widgets, maps, speed test, android OS and advanced task killer 3%, 3%, 3%, 3%, 2% respectively. Still think it's not doing what it should. A good majority of the day I've left it in the off position, not messing with it. 30% by the time I leave work really kind of sucks.
I got the phone Sunday. Used the crap out of it Sunday and Monday and let it run almost down to 0% (it was warning me to plug it in) then let it charge to 100% which took hours and hours and hours. I remember when I had my Iphone down to like 60% when I left work I'd enable pandora streaming and plug it into the car charger and be back up to 85% by the time I got home at least, and it's a half hour drive.
When I plug it into the car charger or a regular outlet I'm lucky if it goes up 2% after a half hour. I'm starting to wonder if this thing has a bad battery.

What is your phone's uptime?
I've been unplugged since 6:45am this morning.. its about 2:40 now and I am at 73%.
I've been downloading apps, playing with androidVNC and just continually tinkering with settings.
My uptime is 111:40:00 and its been 7h 50m since unplugged.
I'm using launcher pro.
I have a bit of speculation that Touchwiz has something to do with it including its special widgets.
Something isn't right with that.

What the iPhone was doing is called a rapid charge. That 85% is not equivalent to an 85% charge that you would get from discharging from 100%

Fair enough. I'm very interested in checking out this article, but I've gotta run now. I was going to give the GPS one more shot on the way home. If I can't get a lock and the battery doesn't get much of a charge being plugged in the whole way I think I may take it back to the AT&T store and see if they'll swap it out or even give me a battery replacement.
Should I reverse the root before I do that, if I do? I know that's entirely off topic. Should I just remove the superuser permission app (if I even can)?
Additionally, just throwing this out there anyway, according to this review: http://www.boygeniusreport.com/2010/07/23/att-samsung-captivate-review/ their camera is awesome without any settings changes.. I find the regular camera kind of blows. I'll upload some pictures if anyone wants to see em, but I used my phone, on the basic settings, to take pictures of my Iphone which I was selling on ebay and the pictures came out kind of crappy, especially for being 5mega pixel. The video camera looks great, but the picture part of it I am really surprised at. My overarching point is I think there might just be some lemon phones out there possibly, and I think I might have gotten one. I'm running into all the major problems that some people are complaining about. Camera, GPS locking, battery, lagginess of the UI, etc. I think I'm gonna try to get AT&T to swap my phone out.
LIke said in other threads, mine just draining like crazy before but now it seems to be pretty bearable. Here are the things that REALLY helped me:
1.Completely drain the phone till its dead.
2.Fully Charge the phone with it off! Yes you can live without it for a little while
3.Disable the live wallpaper,
4.Use Launchpro and heaurisitc which is the vibration when the 4 buttons at the bottom are used.
5.Reduce vibration overall
6.Dim Screen
7.Turn off everything except I run wireless and fring 24/7 basically
AND this phone is fast,
I dunno if its available through the free launchpro, but I paid for the plus and its sooo fast.
1.I just disable all the animation crap and everything and make everything level 8 on speed of opening up
2.Disable the elastic animation when moving from screen to screen....
3. I would really suggest people pay for launchpro plus, cause its cheap and the work is almost gods gift to cell phones ahahhaa....
Hope this helps....
7am and now its 1PM with Wifi and Fring on since 10am and last checked its at 80% with a 15 minute phone call. and messaging probably 30 messages.
I am going to drain it till its dead tonight again and fully charge with phone off again. I think this helps a lot.
I unplugged my phone at 8:30...listened to an hour of Pandora, checked email, and was on Twitter...down to 85% at 10:30 which is pretty good to me. I also don't have a task killer installed for what its worth.

Well Update around 30 minuets my phone completely died for the first time so I am charging it now, and I am hopeful that it will get better soon.

I just want to mention that I swapped out my captivate at the AT&T store yesterday. I let it almost die, then charged it to full, unplugged it for 5 minutes, charged it to full again, unplugged it for 5 minutes and charged it to full again and left it connected over night.
I've been using the phone all day today, changed settings, texted, generally used it, since about 6:45AM and I'm at 71% battery at 11:35. Insanely better. By a lot. With the old phone I'd be at 30 or 40% by now, honestly.
Additionally, the screen seems much brighter, even at the lowest setting. The camera seems to take better pictures and everything seems much snappier and quicker on the phone, by a lot.
I got the GPS to lock on once, and while it wasn't perfect, it followed me, and then I couldn't get it to lock again unfortunately, but I'll keep messing with it. I think it's a samsung update issue anyway, with regards to the GPS.
I really and truly believe that I got a lemon phone. I know that the AT&T store by me sold out on the first day so I definitely got this one from a different batch. This is like a totally different phone. If anyone else is having these kinds of problems with lag and battery life and things, try getting the AT&T store to swap out your phone. You have 30 days.
The iPhone and many other phones like the Droid charge faster for some reason.
From my Samsung Captivate
Is there any way to get this thing to last over 10 hours with moderate/medium usage? I mean I hate to compare, but I was able to use my iphone 4 hard periodically through the day and be at 40% around midnight, but I have to stay using my captivate very lightly after about 10pm, and I usually unplug around 12 to 1pm..
I don't want to have to sacrifice majors perks of why I switched to android just to get a full day out of it. I've tried a lot of the suggestions I'm the forums, but nothing makes a notice difference, or makes it a fame changer as to where I'll get a full day of moderate internet/media usage
Thanks in advance.

Have you tried draining and recharging the battery as other threads have suggested? I usually unplug around 9-10am and I don't get battery warning until near midnight or later.
I keep seeing people complain about the battery life constantly.. but to me coming from my bb bold it seems that the battery is lasting way longer then i expected.. first couple charges i let the phone drain down till it shut off, and then charged it 100%.. its still new to me so im constantly playing with it and changing the menus around.. i try to make sure almost everything is closed when im not using it.. cause im sure that eats battery life..

I did it once, but I booted back up the phone a few minutes after I plugged it in, will leaving it off while it does a full 100% charge noticeably increase battery life?
Do you have widgets updating frequently? How frequently? Maybe just too many updating widgets. I get about 18 hours with the screen on for 4.
18 hours also
I'm getting 16-18 hours of use with about 4-5 hours of screen time. Better than expected.
Today I used my phone as much as I used my iPhone 4 on a regular basis. My phone has been off the charger for just over 12 hours and I have 70% of my battery left.

I'm around that too, I use a black background to save power and I have about 5-6 hours of screen time and I watch a movie on it every day (treadmill at the gym)
I only get low battery around midnight
I use advanced task killer and set it to when the screen is off to kill apps, aggressive mode, I can go about 20hrs before I need to recharge. 5-6hrs screen time.

One thing about android is it has true multitasking. Combined with some apps which do NOT close properly and continue to use up CPU this can drain your batter very fast.
In the battery Info your TimeSpentAwake should be ~ the same as Display on time. If not something is not closing properly. Use OSMonitor to check which program it is and either uninstall it or make sure to kill it with task killer after using.
I have the M110S (Korean Galaxy S - I get 16-18 Hrs with moderate use, but M110S comes w/ 2 batteries so i just swap )
Yeah based on people who are getting good battery life mine is absolutely terrible. I am on my fourth full discharge. I have had my phone off the charger for 2 hours and I'm already at 87 percent. I listened to about 45 minutes of cached slacker radio and like 2 posts on xda app

Just to comment on my battery life. I got my phone saturday (2.5 days ago) and its been on the whole time with medium usage. When I got the phone the pamphlet inside said "fully charge before you turn on" and thats what I did. My battery is at 41% and the only time that I have charged it since is when I am connecting it to my PC for a very short amount of time. I have had great battery life so it is possible. I am very impressed with it.
Yes...my battery life has been good...
Screen brightness all the way down (auto brightness off) *same for the browser brightness
Screen timeout 15 secs (annoying sometimes so maybe 30 secs)
No window animations
Power saving mode off (no point in having the lcd adjust if its already as low as it will go)
I also dont have any widgets that update in the background, however i'd imagine one or two wouldnt affect the battery much
These settings have worked out for me and i use the phone moderately with 2 hourly updating email accounts.....

Battery life for me has been decent. I consider myself a moderate user and I can go from 7:30am till I go to bed at night without dying, but its close. Coming from an iPhone 2G, where with the same usage I could get 2-3 days on one charge, its a little disappointing. But it is what it is I guess. I have heard horror stories of EVO's only going 4-6 hours on a full charge, thats ridiculous.
But what gets me is all this nonsense about fully discharging before charging back up every time. These are Li-ion batteries, they are not Ni-cads, they will not get a "memory" if you dont fully discharge every time. Yes, its good the very first time, to fully charge it before using it, but after that, it doesnt really matter.
Also, one more thing I noticed. The phone will stop charging the battery the second its fully charged. So if your phone reaches 100% charge at like 2am, it stops charging at 2am and you are then going from 2am till whenever you take it off charge in the morning. I noticed this the other day. As soon as the phone told me it was fully charged, the battery icon turned into a normal battery icon even though it was still plugged in. So its possible that the phone is going for 4, 5, 6 hours off charge before you even wake up. What I do to make sure I'm at 100% when I leave, is when I get up I unplug it, use it for a minute then put back on charge while showering. Then when I leave for work, I know its fully charged at 100%.
I guess I'll be switching out phones at Best Buy today as well. Phone keeps losing 30-40% overnight (more like 5 hours max since I'm a night owl) even with everything turned off. When I do get back to a 90% charge before I leave for work at 8am, I'm usually left with 30-40% by 5pm after 15 texts or so and a few emails.
I am fairly sure all new batteries have a chip in them that regulates the power. So you HAVE to run it down to 0-5% and charge it back too 100% several times before the battery is even calibrated for use. That has to be why its 50/50 battery sucks battery is great, just let it drain and charge it again.
battery life simply not acceptable
Hey guys,
I know many people post on battery life.
Here is my situation.
I do not care about beauty, but functionality is a must.
I am in the hospital from ca 6am to 7Pm and I have Q4 call meaning every fourth night its to midnight. That is simply a fact of my life.
My requirement:
I need my phone to last for this duration without recharge.
1.)
I don't need or use widgets
2.)
I don't need or use a wallpaper other than a solid black background.
I do need and use:
the GSM radio and wifi both need to run the entire time and reception is what it is.
My applications of use:
merck manual, dynamed, epocrates the usual in my boat.
I really really want to use this phone, but battery life wise only my blackberry with extended battery and my iphone 4 can hack it.
If any of you have any suggestions on what I could do plz let me know. My last resort is carrying two batteries, but that would frankly be admitting that this phone is inferior to the iphone 4 which can hack a 20 hour usage day in my setting.
(I absolutely cannot turn wifi or 3G off both must run)
I am open to all suggestions including the task killr controversy or anything else constructive one may have. Any extended size batteries out there for the captivate?
Thanks a bunch in advance.
(Having had my secretary spend 4 hours rooting the phone and sideloading Merck manual is a testament to the pathetic entity that is AT&T by the way. If you have professional apps from an institutional subscription you cannot download the software from the market...)
PS: My secretary is not exactly a hacker so forgive the 4 hour timeframe.
I consider myself to be a heavy user!! I like to text, browse the web, listen to music (either from my own files or streaming,) check email and comment on facebook all throughout the day. I did that perfectly fine with my Bold 9700, that battery lasted a full day or more.
I had an iPhone 4 and my battery would not last my 8 hour work shift!! I either had a bad battery or who knows what was going on with that phone. I didn't even leave the apps running...the phone was nice, but that battery killed it for me. I don't understand how some people got a full day out of it.
On the Captivate the most I have gotten has been around 10 hours of use and that's not even using it how I normally like to. I stop charging it at 8:30 and my battery is 100% around 10am I'm already in my low 90's or upper 80's. I don't have any widgets updating, I have a black wallpaper, I don't have the haptic feedback on, and I sync email hourly.
Could my battery be bad?? How can some of you manage to get 16 or so hours out of it??
As stated above, I'm curious what the answers will be.
We obviously can't define "heavy use", but I think everybody gets the point
I'd like to ask the 7-8 guys how they do it?

I use auto brightness.
Also, when I got the TF I did the whole break-in thing. It was in the manual.
Now, if you want to get better life you can reset your lithium ion battery. Use it till its below 5%, maybe even go to 0%, then charge it to 100%.
Do this atleast twice back to back. You should see your life grow.
Also, never over charge it, and never leave it charging at night. Even though some people will tell you it 'stops' charging once it hits 100%, it actually goes to trickle, and trickle or not, its still over charging it.

Manual says "to prolong battery life fully charge the battery for up to 8 hours when using the Eee pad for the first time and whenever the battery is fully depleted" Often wonder where you get these post that say don't leave it charging for more than 2 hours.
Auto brightness is really dim on my old eyes
BTW I have a dock and get a lot more than 7 or 8 with it ...very close to the 15 or so they say ..it is according to what your doing...if your playing games, watching flash or movies your mileage will vary
Same here, I usually just watch movies, (occasionally getting distracted by some tower defense game), but apparently my overall usage is due to the screen brightness. I had it on autoadjust for a while in the beginning (lasted like 8 hours) but then I don't like (is there an adjust option for autoadjust? it'd be a lot better if it made it just 10% brighter than it usually sets it..) the autoadjust, so now I usually have it on like 60-100% brightness and I still get 6-7 hours on it. Then i just dock it for another couple of hours.
Hm... too bad I like bright screens
So maybe that's the reason mine only lasts 3-4 hours :S
We'll see later on, maybe it will improve!

Wow. I have mine cranked and it lasts well over that. Closer to 6 with consistent video watching.
i mostly use mine to browse online and music etc,i get around 9 hours with auto brightness
*added*
i used systempanel to monitor when i sleep to check usage,its between 1~3 percent for the cpu, battery life stays flat lined. cpu activity averages 30% while device is at 100%. i use advance task killer and juice defender and disable connections and sync etc.
well one thing for sure, my mifi died before my transformer died, so i roughly say 6 hours ++. when in music, it saves a lot of battery.

2 hours is silly. Mine takes at least 2.5 to charge to 100%. I'm not sure where you've read that, but don't believe it! lol.
Li-ion batteries are great because they are extremely flexible and charging them like 5 times a day isn't a bad thing like it would be with an older technology.
But they are still susceptible to overcharge issues because they generate heat when charging, and that heat changes the composition of the battery, which makes it last less and less over time. That's why li-ions hold roughly 50% of their charge after 1.5 years of use.
And that's why one shouldn't overcharge it.
about 6~7 on stock..just recently tried prime 1.7 so will check for any changes
Does Netflix count as heavy usage? if so then I get about 8 hours
I use mine to browse and to remote desktop to my PC. Sometimes i use gchat and other times play a game or two. I get around 7-8 hours from the eee pad only. With the docking i get much more.
I use auto brightness, and wireless off when screen is off. This way i can leave my tf up and running all night and is ready to be used at any time. The main power consumption are the screen and the wireless on my usage profile. Both together consume more that 70% of my battery.
Is it possible to switch off the wifi automatically when the screen goes off?
Yes, of course. Go to wifi-properties, then choose extended (on German: "Erweitert") at the top right and there you can choose your setting.
(I've got a german TF - there it is "WLAN-Einstellungen"->"Erweitert")
With auto-brightness and wlan-off on screen-off 9 hours is no problem.
Great Tablet
I run Clemsons V4 Final, no dock and have the screen timeout set at 30 minutes. I didnt pay attention to the recommended battery stuff in the manual. And usually leave mine on the charger all night to be sure I start the day at 100%. I use my TF all day for work, taking notes, surfing and so on. I generally get home with 40%, if I dont play Angry Birds. I have played just music for 8.5 hours continuous with a 15% drop in battery.
Not iPad performance but still a keeper.
I put 6 hours of HEAVY use, but I usually get a full day's usage out of it since I keep my pad tethered to my charger at my desk all day at work.
tried the break-in charging thing (drain to 0% then charge it for 8-9 hours). My battery life changed drastically. Did it only once but ill charge it like that again when it depletes to 0%. It running now on its 3rd day with minimal to moderate use (28% as I am writing this). Will post battery drain per hour once done with the 2nd charging
No Dock, 2 Mobile Data Application frozen via Titanium back up
According to some review, infinity should give 9.5 hours of play time with WIFI on. Different use results in different result for sure, but I feel like my battery life is less than that of Galaxy 10.1 and if I remember Xoom. Not matching up with iPad is understandable as no android tablet does as iPad does no multi-tasking and wifi turns off quickly after sleep. But worse than Xoom or 10.1 seems something potentially wrong with my unit.
Is there any official application that can test battery condition? In Mac, there is application called coconut battery which tells you how much of battery you can charge i.e. no battery is usually 100% of its maximal capacity and over time it loses capacity gradually but this application tells that. I wonder if there is similar for Android tablet.
By the way my usage is like reading book and comics, surfing net, not much of game. I'm in balance mode. I checked turn off WIFI while in sleep. I did 1GB+ file transfer over the WIFI. With this overall screen time of 5 hours and I only have 15% battery left. I probably won't make it to 6 hours..
Ehhh... as far as I can tell, the Prime (and consequently, the Infinity) should outrun any iPad as to battery life. What's your scree brightness?
I get like 6-7 browsing, 9-10 reading pdfs and much less gaming (balanced mode, brightness 30%). You can see some averages and estimates in the Battery HD app / widget.

Outrun iPad?? Maybe with the dock. Sorry...

On the crApple forums, loads of people report a consistent 7 hours of use for the iPad3 (or the new iPad, or whatever the thing is called). The TF700 should eat it alive with the dock attached, whereas they'd come out about equal when going face to face 'barehanded'.
EDIT: nice test: http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html of the OLD iPad2 vs. Transformer 101. Yes, agreed, it is old, but the iPad3 has double the power consumption and only 70% more battery capacity. You go figure.

I agree with the table as I owned Xoom, Galaxy 10.1, and currently have iPad 2 and Infinity. I don't know about New Ipad. But in my experience iPad 2 always give solid 10 hours or so but again that's probably not fair comparison against Infinity which uses HD screen. So I was going off of http://www.engadget.com/2012/06/25/asus-transformer-pad-infinity-tf700-review/, which shows Infinity having superior battery than the most of newer versions of Xoom 2, Galaxy 2 10.1 etc. I have no doubt with Docking station, Infinity's battery life would be unbeatable except by transformer prime.
But my concern was actually if my unit battery is semi-defective and not charging to full way.
I usually have my screen brightness turned all way down; whereas, above test is 50%... so I was surprised my result. Unless 1GB transfer consumed so much or overnight standby consumed a lot (despite turned off WIFI box checked..). Since we cannot really go off by battery screen on ICS with inifinity, which shows WIFI more than screen... I just have no good way to assess the condition of my battery...

Are you sure that you Infinity is going into deep sleep? There are many cases where a "rogue" app will cause the tablet to never enter deep sleep, thereby draining the battery much faster in standby. You can check for deep sleep with CPU Spy...

I still need to do a scientific test but today at work my screen was on for 3.5 hours and the tablet was off the charger for 11.5 hours. My battery was down to 32%. My screen brightness is IPS off and fixed at around 90%. Looks lovely
I ran my xoom for 2 hours even and 2 hours off charger. During this time however I downloaded a bunch of apps, loaded up all the apps, ran weather bug looking at weather maps, and did some browsing. I was using it continuously to get the feel compared to my infinity.
Anyway after all that the xoom was around 77% batter remaining.
I know that when I tested my xoom soon after I got it I could get around 6.5 hours on the screen before it ran down. On standby it barely uses anything. I'm guessing I use it at work around 3-4 hours. Sometimes I'd forget to charge my xoom and the next day it would usually get me though most of the day... To maybe 1-2pm and I come in at 6:30 so thats almost my whole day.
So yes the battery is definitely less. Tomorrow I'm putting the screen brightness on auto. Thats how had the xoom so maybe it will be a better comparison. Certainly looking at battery usage the screen was using a lot of power. What looks REALLY odd however is that wifi is my number one battery usage.
That just doesn't look right does it? Now I do have it on wifi all day so in this case for 11.5 hours. But I don't on my phone wifi is like 3%... Maybe my tablet and problems are related to an issue with wifi?
Anyone else keep their wifi on notice a big power drain on wifi?
check to see if you have a battery leak with some app. turn gps off, dont use auto brightness lol. keep it down more like 65 % indoors you dont need more than that. use the app called juice defender and make sure you kill off anything your not using. google a list of top 10 thigns to do to android to make battery last longer

Yes - I do. My TF700, no dock, seemingly handles just about 4 - 5 hours of activity (not stand by but actual use, be it video, audio, browsing, etc), and when I look at the battery stats under settings - it shows that over 80% went into wi-fi.
I have heard that to make up for the weak Prime's reception ASUS overpowered Infinity wi-fi, so it sucks power out of the battery pretty fast.
I am also assuming that as usual, based on latest update, serial number, QA, etc, the behavior will be different for different tablets, some will see it and some will not.
Good news is that these things are fixable by a soft patch, so we shall see something released by ASUS if many people complain.
So I still have to do more testing, but I guess my tablet is not defective (at least in regards to the battery). i do get pretty much the same result as others replied me back here. After checking the ASUS main site, 14 hours with Dock was measured in Power Saving mode, 720p movie, WIFI on.
So key here was indeed power saving mode, which I was not using. i just switched to Power Saving mode and just looking at 10% drop mark, it seems to go ~50 minutes, which equates similar to what 9.5 hours one site suggested. Application (as far as what I use) runs fine and seems as smooth BUT main thing noticed here is refresh rate of the screen in power save mode seems much lower so when I go back to main screen, i can see some flickering.
But it's great to be able to boost battery life by couple hours and more.
With the device off - - after a full charge, my battery says 97 percent....NEVER 100%. With the charger plugged in, while using the device, I get a max 98 percent charge. Anyone having a similar experience? Does the device actually use 2% of
the battery when turning it on? I'm befuddled.

Do you usually drain the battery all way down after each use or close to it?
Got my tab yesterday. After charging I did some I would say normal usage, browsing, installing some apps, transfering data, watching video and a cam chat for about 2 hours on skype, standby over night.
I used balanced mode, auto brightness, external speaker on highest volume, sometimes superips (but not for long), always had the external sdcard mounted, always wifi on, gps on, autorotate on.
I had >14h without the dock, should have made a screenshot.
I will do a drain test when I charged the battery 4 or 5 times.

Also when the device is charged up to 80% disable everything, wifi, gps and so on.
Then suspend the device and do not turn it on for at least 1 hour.
I do it that way and get 100%.

Got my replacement yesterday. That was my first full charge. I allowed it to charge to 75% then turned it on (while still charging) and set it all up. I had the charger plugged in for 10 hours while playing around with it. Went to bed, turned it off and let it charge for another 4 hours. When I turned it off . I noticed it was only at a 97% charge.
I'm using it now to let it drain to zero. Then will do another full charge. I've only had it on for 90 minutes on balanced setting and the battery is already showing a 40% drain.
For those worried about the battery only being charged to 97-98%: it's normal, and a way to conserve your battery. Li-ion batteries don't like going to 100% full charge since it increases the temperature a lot and in the long term reduces their capacity. So the battery gets (very shortly) charged to 100% (or very close to it), then it will decrease slightly to high 90s and the charger will go into maintenance charging, keeping it close to 100% charge.
Some manufacturers "masquerade" this by setting the percentage to show 100% even if it really isn't. Keeps users from losing sleep over trivial things like that
The batteries don't like deep discharges either, so there's no use emptying them completely. Top them off whenever you can. Anywhere in between 40% and 80% is good.
TL;DR: Don't worry, the battery is fully charged even though it says 97 or 98%. Don't empty the battery completely.
Edit: Some useful information regarding Li-ion batteries here, http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries/
Thanks for this, but there was some discussion with these studies already. But probably it's right not to do anything extreme.
That being said, we probably have to admit that there is a reason to DISCHARGE and CHARGE FULLY a few times - so that all the apps/widgets that measure battery capacity, estimate life etc. could learn all they can by more (and more exact) data.

Thanks for the info! Good to know that you don't have have to do a complete battery drain, initially. Or ever for that matter.. :good:
Hi everyone, I'd just like to ask what's the average battery life of the G Pro 2? I somehow feel my device drains really fast for what it's worth.
I had around 3 hours of run time and it went from 100% down to 85% with only 53mins of screen time. 2 of those 3 hours were used on 2g, text messaging only, when I got home i used facebook and wifi for about 30mins (but wifi connects as soon as i get home).
so I'd say around 15% after 3 hours of moderate usage. is this acceptable? though I'd like it to drain a little slower.
I'm currently on V20a Lollipop, rooted but stock everything. also the brightness was set to 20% the whole time.
Could anyone also help me out (like literally hold my hand) in choosing a lightweight, resource saving ROM? Kernels are a bonus but right now, it's a bit unsettling to see lollipop eat away 6gb of my already small 16gb internal storage.
My device is still 2 days old, so I'm still a bit jumpy with it xD thanks in advance!
no, thats not normal. what does the battery option say uses most battery in settings?
UPDATE:
just did another 3-hour monitor, right now I'm looking at 3h10min on battery and it dropped from 100 to 91%.
WIFI was on but I didn't use it, 50min screen on time with 15min of voice calls.
Is it just me or is Lollipop a bigger battery drain than kitkat?
BUMP
here's what i've got:

You're pretty lucky, on an average I get 3 hours of usage from my phone. Legitimately from 100%-0%. On WiFi using only WhatsApp, playing a few rounds of a game and some music. Don't get me started on when I use it for navigation.
UPDATE:
I forgot to mention in my OP that i already had Amplify and Greenify and still had those kinds of stats.
Now I installed DS battery saver to drain the least amount of battery when I'm not using the phone, and so far it is GREAT.
Before I left for school (around 12:30pm local time) I was able to charge it to around 85% and as of writing (1:27am) it's sitting at 33% with 2hrs of screen on time. Note that those 2 hours I used for gaming, youtube, app downloading, and web browsing on wifi; I guess it's also important to note that I play really heavy 3D games (Maersk's quest for oil for instance).
Considering the load i placed on it for those 2 hours, I'd say battery life improved quite a bit, though not amazing, still a lot better than before.
When screen is off, it drains less than 1% an hour. I went to sleep 3:30am with 100% charge, woke up 10:30am with 96%, in 7 hrs i lost only 4% while the screen was off (compared to around 10% for the same amount of time before DS Battery Saver)
I encourage other LG GP2 users to try it out. Root your device to be able to use the "tune cpu" option.

What rom are you using? i had a problem charging my Gpro2, it takes 4-6hours to fully charge.
i don't know if its a hardware problem or kernel/rom..
I'm using LP rom and rooted, i also use amplify, greenify and DS battery saver. i'll get back after after a few test this week, i'll check my cable, adapter then replace my battery if necessary

Using stock LP rom V20a but rooted. Are you using the charger and cable that came with the device? I believe it was rated 1.8A. I tried 3 setups since it was weird because it originally took me 3hrs to fully charge:
1.) New charger + cable (the ones that came with the phone)
2.) My old LG Optimus G's charger + new cable
3.) Optimus G's cable + new charger
I tried these setups out on the same outlet and the new charger+cable charged faster, but it was still around 2hrs or so. So I tried it on another outlet, one that we (my dad and I) attached, and voila, around 1hr 30mins to charge while on and even less that when the device is off; note those numbers are for 0~100%
We're just living in a rented house and some of the outlets are pretty old, and I bet delivers low current (possibly due to small wires) while the new outlets we attached used high-gauge wiring.
If you're charging slow with the charger and cable that came with the phone, try to charge at another outlet that uses high gauge wiring.
