Is anyone that is having battery issues running Adao Task Manager and Battery Status Pro?
I just factory reset my phone and I got 24hours of batter life. About 8 standby but a good deal of texting, web, some calls and some you tube.
I installed Task Manager and Batter Status Pro last night and my battery this morning went down 15% in about 1hr.
I uninstalled these today and will post again but has anyone else seen big battery drain from these apps or does anyone that is having issues running something similar?
I have been playing with the battery for about a week now.
For me this phone runs pretty good during stand-by. I would have about 2-3% drop for a whole night (7 to 8 hrs), with Google (push), Twitter and weather syncing.
The problem is when you use it, it drops like crazy. When I read news or surf the web, it would drop 1% every 1 or 2 min.
This morning I read an ebook, with black background for about 30 min, it dropped about 3%.
So basically i think the screen, data connection, and non-black background are the ones that kill the battery.
Yea, I agree, the S-AMOLED screen in this thing is an energy hog. OLED's are supposed to be more energy efficient than typical LCD's but I'm just not seeing it. Whenever I look at battery usage stats it shows the display at 70-75% of battery usage. Thats ridiculous. I have until the 18th, but I'm quickly leaning towards returning this and just getting an iphone4. This phone is becoming more and more disappointing the longer I have it.
This morning I have been uplugged 4.75hrs and used 16% no battery monitor and no app killer. Basically done the same things I did yesterday. Some Bebbled,texting, email, phone calls .
I will update tomorrow with total hours battery life for today. Would be happy if I can replicate the 24hours I got the day before installing those apps.
I got like 45 hours of battery with moderate usage during the two days. Seems fine to me, I occasionally used system panel to monitor if anything was using high and constant CPU
This is pretty typical of a 1ghz phone My nexus would last a day of heavy usage, 2 days if i use it lightly. We need to wait for undervolted kernels to be developed xD
Also, it really helps if you disable 3G when you don't use it. This allows me to get 3-4 days of light usage out of my nexus. I haven't played with the Captivate long enough to know how much of a difference this makes on this phone though
when you guys refer to "stand by", what exactly do you mean? Just screen off/phone idle? The battery usage on my phone when I use it seems to be OK even if not amazing, but it continues to sap life from the battery when I'm using it at an alarming rate.
Standby is when the phone is idle/screen off/locked.
The display is definitely power hungry. Using the Power Control widget that comes installed definitely has helped with battery life. It will let you toggle WiFi, BT, GPS, Data Sync, and Brightness (at 3 levels). When I'm not using anyone of those, I turn it off. When I'm indoors, I'll set the brightness to the lowest level. I'm usually at my desk when I'm streaming music, so I'll have it plugged in.

Actually they are more energy efficient on black screens, But screens with a lot of white in them suck battery bad.

This is true the white screens burn the battery etc. I just wanted to let everyone know what I did to make my battery last more that 24hrs.
First, read the Wiki guide and apply some of the battery saving tips.
Second, UNINSTALL a program called "gReader" created by noinnion. This program is a huge battery hog! At least it was for me.
Hope this helps.
Well I guess I am one of the "lucky ones" Im running a live wallpaper and have not run my battery down since the 1st day. Right now Im at 40% life and at 15 Hrs 30m since unplugged. This is with checking facebook, twitter, email, phone calls, internet browsing\video watching and following the steps for the GPS fix. The only thing I have done is install ATK on the phone, besides that its all stock.
One thing I know is a huge battery drain is Time without Service. Check that stat and see if you have anytime at all without service, if so, I am pointing to that as a major drain on the battery. I know currently I have 0% Time without signal, my fiancee however is usually in the 20+% range and her battery drains like many reports I have seen here (she has an EVO).....
Yesterday I only managed 16 hours. Web, Email, A bluetooth file transfer, short bit of gaming. I have about 5% of the cell standby time (26%) without signal. My girlfriend has the Aria which is running Android 2.1 also, has all sorts of widgets, haptic feedback on and can make it at least 24 hours. I get that it has a smaller screen but it is also an LCD. Shouldn't the Super Amoled be saving our battery some display consumption.
i get about 14 hours or so moderate usage and at the end of the day, i have about 35% left at night.
If you detail the "Display" usage in the battery usage details how many minutes has your screen been on? Mine says 1hour 2mins ...this is for 8 hours of running time. My display is using 50% of the battery (which is at 68% now).
W00t W00t today I have reached a new high 2 Days 6 hours and 29 minuts with 12% battery left.....
What I have found is keeping Wifi on while I am at work and home like almost doubled my battery life. Which is great that I can use Wifi all day and not drain the battery so fast like my Fuze. Right now been off charger since 7:30am and I have 84% left. Yesterday after 9 hours I was still over 50%. For me its better than any other smartphone I have owened.
I used manual brightness, (swipe notification bar), turn off GPS/BT. black wallpaper and set Wifi to never sleep. Also the power saving mode in settings is off for other reason and doesn't affect battery.
At 18% right now and it's been off the charger for about 30 hours. I noticed yesterday that while I was connected to wifi at home (with Y5 app), it was draining faster than when I was connected to 3g. Did some tested back and forth and JuicePlotter clearly had a noticeably steeper downward slope for when wifi was connected than when it was using 3g. Weird :\
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.

Thanks for the answer,
I unfortunately don't have the manual with me, but true, I just got the tab yesterday. So do you think in time it will improve? What is that break thing you mentioned?

Mine has also got better only thing that kills the battery is playing Galaxy on fire 2 other than that i watched two 2 hour long movies and still had 40 % left

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

Anyone know where to get an extended battery? Thanks.
I can't even find a place to buy a regular battery for the phone. I'm not sure if I would need one, but it would be nice to have. I'm in the habit of charging it the last hour I am at work so no matter what, I'll never run out of battery even if I go somewhere straight from work, but a spare battery is always a good thing to have.
I have a wild guess as to why not.
I noticed this phone battery has the "near field communication" labeling on the BATTERY. The other phone that I'm aware of having NFC, (the galaxy s2) does NOT have this wording on the battery.
Why did I notice this? I randomly read that there is an SD card manufacturer that is putting NFC chip's into their microSD cards, and even some ipod cases are getting NFC chips built into them as well.
I don't know too much about NFC, but with the labeling being on our battery, and not the S2, I kinda think our NFC chip is actually in the battery, and not the phone itself. If an NFC chip can be put into an SD card or case on a phone that never had NFC to begin with, I don't see why it couldn't be put into a battery, especially since one of the terminals might not even be for power, but just for an NFC connection.
That's my theory, I could be wrong!
you're probably right. This is how it is with the Galaxy Nexus, also built by Samsung. I hadn't noticed the label, but I also wasn't looking for it.
I'd be curious to find out what an "extended battery" for this phone would look like. I'd be all for it so long as it kept NFC and didn't bulge out of the back
I'd be interested to find one. Being on a stock rom and standard battery, my battery drops about 5% in five mins just checking Facebook. GPS drains it another percent per min it is in use. Half way thru the day my battery is dead. It really sucks having to carry around a charger. I'm also using juice defender and other tweaks I know to save battery
I'd bet you a waffle cone your screen brightness is set too high.
Forget most of those "battery defender" apps, especially if they are those stupid task killing applications.....a program being in active memory is not necessarily actually doing anything, which means it is not using your battery, and if it gets killed, if the OS needs it open for any reason, it having to be re-opened will just use cpu cycles anyway
I'd agree with most people that using the automatic brightness option is very annoying, it's really sensitive and it also tends to make the screen not be bright enough. Having said that, using any of the many available brightness widgets can be a very good thing.
The stock one is not so bad, personally I've been enjoying powerful control, http://goo.gl/2vZXl but I've had great battery life and easy readability if I use the brightness setting where it looks like a half moon.
If you're outdoors in the bright sun, you'll need the screen to be as bright as possible if you want to read it, but otherwise it's fine. The screen brightness is always the single biggest battery usage factor.
Personally I've always disabled the haptic feedback as I think it's annoying and I'm sure that using vibrating alerts is also a huge battery drain.

My screen brightness is at zero without automatic brightness on, and im not using haptic feedback. The phone battery is fine if its just sitting over night, but as soon as I turn on GPS to use maps for 5 mins or to check facebook the battery just drops a % every min. So i guess the phone is fine if Im not using it, but then whats the point?
You're exaggerating.
I've never had a phone battery drop 1% per minute.
Look man, I just spent 5 minutes playing music at max volume, while getting directions to 8 different places in google maps, sent two emails, downloaded a new app from the market, and received one text message.
Battery level after all this? Still at 100%. Does that mean I can do this an unlimited number of times? No, it does not.
Frankly, I don't believe you. I've used this phone, and my previous phone for playing movies at full screen brightness with the audio being played through bluetooth to my stereo headsets. Does it effect the battery status? You bet it does.
Two weeks ago when I last played a snes game on my phone I did so at full screen brightness over bluetooth to a ps3 controller. When I wasn't playing the game I was sending or receiving text messages and had vibrate on. I played super metroid from the very beginning to almost through the end of the game. When I play snes games on my phone I tend to use quick save and quick load and frame skipping very commonly, effectively letting me do things "perfectly" but this is a lot of saving and loading and running the game even faster than how it normally is. I started at 2, and the next thing I knew it was 6:00 and I was supposed to meet a friend for dinner at 6:30.
But for crying out loud you are saying you can drain your battery from 100% to zero in less than 2 hours.
I'm calling shenanigans. I don't think you could even do that intentionally, unless you sat there and forced the phone to vibrate the entire time.
Phone batteries don't last for days like they used to. Batteries have not changed too much in the last few years, but the things phones do, and the screens they do them on certainly has. Stop expecting your phone to last over the entire weekend even when you actually use it.

Something to keep in mind:
When this phone hits 100%, it STOPS CHARGING. Even plugged in, it will no longer be drawing power into your battery, yet it'll still be running on battery.
If you plug it in when you go to sleep, it finishes charging within 2 hours, then it goes 6 hours idling on battery power but it still says 100% until you disconnect it. Then, while you're using the phone it'll adjust as you use it until it gets to the right level. This is likely what you're seeing.
If I use my phone from the moment it finishes upping to 100%, I get great battery life. I get great battery life in general and have been happy with the phone.
Of course, this might be a totally different issue where you just got a bum battery. But it's something worth considering.

I don't believe this is true. I hate to constantly be a naysayer in this thread, but this didn't seem logical to me so when my battery went to full, (when the battery is full, unplug charger text showed in the notification bar) I kept it plugged in and set it to play a couple tv episodes on full brightness while I did laundry and made dinner.
Two hours later, I first looked at the battery status while the phone was still plugged in. As expected, it was at 100%.
I unplugged the charger, waited a couple minutes, and checked again.
Still at 100%, which completely makes sense because I've never had a phone that behaved as you've described.
I also would have noticed the battery dying very early, *every single day* because my habit for the last week or so has been to plug the phone in when I go to sleep. I have an app called syncme that pulls files off my computer such as music and video while I'm sleeping, and on average it transfers about 6 gigs of data this way, every single day.
I don't know if you've ever transferred 6 gigs of data on a phone via wifi, but yes, it's not exactly battery power friendly.
My phone's always been 100% battery when I leave for work, just like my last phone was where I also plugged it in at night.
Just saying!

Actually he is pretty close to the way it operates. The way your phone gauges battery life is similar to your car with gas. When the meter reads 100%, it is really more like 98%. When the battery reaches true 100%, the phone will stop charging the battery (but will run off of USB power, not the battery). They do this to account for small variations in the many variables that affect a battery's performance (like temperature). Likewise, your phone will read 0% before the battery is truly completely drained (this is also to protect the battery - they don't like being charged to 100%, nor drained to 0%).
This could also greatly affect your previous test on battery performance. To get a more accurate result, let the phone drain to about 60%, then test the time to drop a percentage point.
What you are talking about is a suggestion that the battery meter doesn't necessarily update it's strength meter all of the time, and you even say that the phone runs off the plugged in power at this point.....

Before you discredit anyones post, you should understand how many battery chargers work, and the importance of them shutting off following a complete charge. Here is a quote regarding Li-ion battery maintenance :
Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible."
Many chargers have this feature built in to avoid any overheating and/or damage to the cell. I'm not saying this is the case because I have not tested whether the battery charging circuit in this particular phone, or it's charger operate, but I will say that this has been the case in MANY of it predecessors.
That being said, I think an extended battery would be a welcome addition to the options of this phone. Mine too only lasts a day at it's best. Perhaps not 1% a minute...but then again who knows?
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.

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...

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.

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.
