Specific Battery Questions - Nook Color General

Hey,
I own 3 tablets and considerig the NC for the wife as #4
however I was wondering if anyone has done some specific battery tests for example:
1) How long from full to empty when reading a book?
2) On stand by
3) Off (you know you charge it on monday and dont go to use it until friday)
4) media play? (mp3, avi's etc)
5) light wifi internet use?
she will use it MOSTLY as an ereader however i will need to use an alt FW so she can load some of her nursing aapps (epocrates etc) but she HATES the 3 hour battery on her augen

For me, using strictly as a reader, it will last between 8 and 10 hours, depending largely on the screen brightness. For example, I have my screen brightness down to maybe 17-18% (roughly judging slider). I get around 8 hours there, but by setting the 'night mode', it bumps it up. As always, YMMV...

cool thanks
anyone else?

In my experience the biggest battery drain is WiFi so I leave it off most of the time. I usually leave the brightness at 25%. I also don't let the battery completely drain -- 10% is about as low as I go. So with those things in mind...
1. Reading: 9-10 hours
2. Stand-by: drops a few % each day
3. Off: I never turn it off completely but I would expect minimal battery loss
4. Media: I only play hardware decodeable media (MP4) and get 7-8 hours
5. Browsing: Not much experience but I would guess 6-7 hours

If you keep the stock rom, it would last longer. I have two. One is running cm7; and one is stock. The stock lasts way way longer.

[Q] Maximizing battery life as much as possible?

Before anyone accuse me of it, I did, in fact, look through the other battery threads on this forum (and other forums, for that matter), and I've already applied numerous tricks. I managed to get my phone to last roughly 9 hours from my typical usage, which now makes it comparable to other phones I've used in the past.
However, in about a day or two, I'm going to be getting a bluetooth headset...which basically means that I'm going to need to keep the Captivate's bluetooth on 24/7 (or, at least, most of the day). I really don't know how much battery this is going to cost me on the Captivate, so I'm trying my best to make things better now to make things smooth in the future. However, I appear to be at the end of my rope.
I have pretty much gimped the Captivate as much as one could reasonably take (more, I'd dare argue). I cut all of my volume down to half of what it was and I removed most of the quick icons. I also set a completely black wallpaper, I turned off all animation, and I turned the brightness down to its lowest setting.
I honestly don't know how to make it any worse. The SAMOLED screen is basically a meaningless PR term to me now and I'm actually missing phone calls from sheer lacking of hearing my phone ring...despite it being right in my pocket.
Going even further, I also attempted to switch to ADW.Launcher based upon recommendations by others that it increases battery life (I found that it had little to no effect). I also attempted to severely underclock my CPU (down to 200Mhz) based, again, upon other claims that it increases their battery life all the way to as high as 30+ hours on a single full charge.
Somehow, underclocking my CPU actually made the battery die out faster.
Furthermore, I attempted to use programs (SMODA, 2G/3G) which claim they allow me to switch to EDGE because, for some God-forsaken reason, Android doesn’t seem to have any toggle for doing it. Unfortunately, none of them seem to work; rather than switching to 2G, they all just completely disabled data, which, unfortunately, is completely unacceptable to me. So at this point, I only seem to have a few more extreme (from my perspective) options. Once I actually get the bluetooth, I plan to turn off most of the auto-updating apps (email, weather, twitter, etc), and just update them myself periodically. Furthermore, I plan to turn off the GPS location feature once I get my GPS unit.
Beyond the above, though, as I said, I'm at the end of my rope. Once I employ the other tricks, I figure I might be able to stretch battery life to 9.5-10 hours, but I would like to go even further. If anyone could offer me some help, I would highly appreciate it.
if your gonna have a bluetooth headset on disable your ringtone completly that would be meaning less. if your near wi-fi a lot have it connect only though that.
also you can clock the cpu down to 100Mhz along with the GPU.
AND to force 2G/edge read my howto in general
oh the ext2 lagfix can also save you some battery life

I'm already doing the first sans disabling ringtone. I'm not so sure doing such a thing would be acceptable to me.
As for the underlocking suggestion, as I said, I underclocked the CPU all the way down to 200Mhz and the battery actually drained even faster. I doubt underclocking even further is going to help. Furthermore, I actually did try 100Mhz originally, but the performance was so horrendous that it was unbearable.
As for the lag fix, I already have it. Lastly, I knew about that 4636 technique to switch to 2G already, but, unfortunately, it doesn't appear to work for me. The setting doesn't save and 3G still remains.
EDIT: I actually found a way to make the above work. Simply dial *#*#197328640#*#*, then go Debug Screen > Phone Control > UE State Control > Change RAT to GSM. This will actually force your phone to use GSM only. This seems like the answer to all of my battery problems....except it doesn't work. Once you make the change, the INFO menu reports that it has been changed to 'GSM Only', but data appears to have been disabled. Restarting your phone makes data works again, but the INFO menu reported that data has been reset back to 'GSM/CDMA auto'. Yay.
If you haven't already, turn off GPS when you aren't using it. Use the Power Control widget to help. Make sure all of the things in the power control widget are off unless you are using it. And use advanced task killer if you haven't already.
i say screw underclocking let run at whatever i dont think it makes a difference.
forget advanced task killer, i like auto killer.
leave gps off unless needed, and backround data
switch to 2g when you can.
no live walls of course use dark or black, no updating widgets
i dumped stuff like juice defender, cause with backround data off i dont think it does anything.
flight mode it at night (when sleeping) if not charging
ive been running jh3 (now jh7) with sre. get to work (i run 2g at work)at 9am listen to pandora all day through bluetooth (which is on for 6-8hrs) and wifi (6-8hrs) good amount off browsing bout 30 min of voice calls, some texts email checking, more browsing, some games. on average lately after being unplugged for 13-17 hrs at the end of the day with 20-30% life left,using bout 3hrs of display, 30 min voice calls, bluetooth doesnt use crap bout 3%, media server usually 15%, cell satndby i wanna say 10%, im pretty happy i guess, even though im always lookin for better results, tryin the new sre with undervolting, heard some good things.
still when that seidio 3200 mah battery comes out im gettin it, dont care how fat it makes the phone, things to dang thin as it is, and without some sort of cover its like a wet bar of soap!!
What is your typical daily usage? I have fairly light usage (few games here and there a little music and a good amount of web surfing, app browsing and texting with a few phone calls using speaker phone) and I'm at 28 hours of use with 55% battery.
I have just the typical power saving tricks(gps off, bluetooth off, screen at minimum or 30% and my data doesn't sync automatically), no under clocking or anything. I should point out I'm running a euro galaxy rom and am not ever on a wifi connection.

Wow you are lucky. Yesterday I got 2 phone calls for a total of 3 minutes. I sent 7 text messages. I surfed the web maybe for 15 minutes. No games. Nothing else major. GPS off. Bluetooth off. Wifi on. Screen at 22%. Only background data I have is email which checks once every hour and a weather widget that refreshes every 6 hours. I got barely 12 hours in before my battery died.

Typical usage for me runs along this line: A lot of web browsing, perhaps 30-45 minutes of music, and plenty of IM. I also use Aldiko to read now and then. Calls do factor into this, but typically only two or three 10-15 minute phone calls.
Truthfully, I simply don't see how it is possible for you to use the phone for 28 hours straight and still have 55% battery. I could lose 30% battery just by leaving my Captivate on stand-by for 30 hours.
I certainly understand the interest in having the best battery life possible.
Are you in a work environment where you cannot plug it to a computer for part of the day?
Fortunately, I am. And I always have it plugged in in the car.
I don't want to have a powerful phone with all the features turned off in order to keep it going.
I dont see how you can get 28hrs @ 55% either, with the kind of usage he was claiming, i wouldnt exactly call that light usage

Well, I do have a work environment where I can keep my Captivate plugged in, but only half of the time. Other times, I need to move. Aside from that, it kind of annoys me to use a phone attached to a wall socket. I prefer to keep my smartphones plugged in only long enough for them to fully charge (or at least charge to 80+%), then unplug them for usage. This is kind of tough for the Captivate considering it takes 3-4 hours to fully charge.
I also fully agree with you on the last point, which is what makes all of this so frustrating.
*Sigh* It's really too bad the Captivate is my first Android phone; it's been kind of a negative experience for me so far. Ironically enough, the one issue that hasn't been a problem for me is the one issue most seem to be having -- GPS performance.

I am in class for most of the day so the phone is idle most of the time but i only play about 10 minutes of music with about an hour or 2 combined web surfing and games but my phone is still chugging at 39 percent battery life at 38 hours of usage. I guess that qualifies as light usage then.
edit: jm6 with unhelpful kernel and sre
also, you have let the battery die out completely and recharge completely with the phone powered off correct?

I'm honestly shocked at your usage. Am I reading right that in the 38 hours since you last charged it, you only used it for 10 minutes of music and a combined 1-2 hours of web surfing/games? I wouldn't call that light usage. I would call that hardly any usage.
Under such conditions, I can see why your battery life lasts so long.
I don't see why you can't get a days worth of usage out of your phone. Cell phone calls use the most battery - that is why the phone is rated at about 5 hours of talk time. This would be in the best signal area. If you are in a lower signal environment (especially in a heavy building all day) you will see faster battery drain.
I am not sure why you are bothering with BT if you are only talking on 2 or 3 calls - but if you take 3 15 minute calls that is at least 15% of your battery - the only way to change this is force the phone to Edge.
I would not lower ringtone volume - that is not a big battery saver in the grand scheme of things and you are missing calls - not a good trade off. If you are doing a lot of web surfing, go WiFi instead and you will see big battery imrovements. 3G voice and data suck battery - it doesn't matter if you have android or iPhone.
If you put your phone in Airplane mode you can go for 5 days between charges with minimum use.
The radio does kill the battery, I don't think the battery usage screen really depicts this. Since I've gotten my captivate my old BB Bold (at the time would only last 3 hours due to its degraded battery) lasts days on end with its radio disabled while sitting in my desk. I'd love to see native 3G toggle or at least a captivate catered app, I'd even pay for the latter

Well, that rating is probably the battery life if your decide to talk on your phone for five hours straight. I really, really doubt it takes into consideration the in-between times (games, apps, and, of course, web surfing). Phone calls undoubtedly takes the most amount of battery, but Internet usage is probably second place and, as said, I use that fairly often.
Lastly, I'm not planning to use my bluetooth exclusively for phone calls. I'm going to use it for calls, listen to music on the Captivate, chat on my PC, and so on. It's multi-usage.
Next, you're missing a lot of the things I said. As I said, I already tried numerous methods to force the phone into 2G; not one of them works (they either don't work at all or actually completely disable my data). I'm already using wifi as opposed to 3G as much as possible.
Lastly, I'm sorry, but using airplane mode to save battery is not acceptable. If I'm even willing to consider this, then I might as well just turn off the Captivate to save battery.
I just read something about an external sd card being another battery drain.
Took mine out and we will see. I was already getting through the day with about 20%left.

I didn't meant to suggest that airplane mode was an alternative, just to point out that the cell radio for Voice and Data is your biggest drain.
If you are going to use the phone for almost an hour of talk time, heavy web surfing and BT connections for tethering then your battery life will be limited. If you are using BT to chat on your pc - then maybe tethering with USB would be better - you could charge at the same time.
Your other option is to get a spare battery.
And I did read what you had to say, I just didn't realize how much you were expecting your phone to do. The only numbers your provider were around talk time.
I use my phone a lot and I charge it every 24 hours - I am more then satisfied - but I know that if a spend an hour or more talking on it and bunch of web surfing that I will have to think about charging it as my usage increases.
There is a way to force the phone into 2G. It isn't very user friendly. I have tested this and it works great.
Enter the Phone app.
Dial *#*#197328640#*#*
Select [1] DEBUG SCREEN

Why is battery life so horrible?!

I just bought a new Captivate (first android device) which I upgrade to from a Nokia E63. I've been playing around adjusting settings etc. and I noticed that my battery is more than 20% drained already! Is there something wrong with my model? If not, what can I do to save my battery for when I really need it?
If all you're doing is playing with it yes its gonna go down. Also depends on what programs is any you have running in the back ground. Furthermore if your wifi Bluetooth and GPS are all on there's another drainer. Last make sure you have the latest update. Usually the out of the box captivates don't have the 2.2 so use the kies program that's on the disk that came with it.

If the battery is new its going to drain quickly at the beginning, after a couple of recharges its going to get better. Other than that i would set the display brightness to auto and i'd download green power free from the market to toggle wifi/data and have it turn on for 1 minute every 15 minutes to save the battery.
i never understand why people complain about battery life cause i can go more than a day without charging, but here are some tricks. turn off wifi, and blue tooth. also under volt your cpu to save more power. also get a dark background because amold screens use no power when displaying black.
It is all in the way You use it.When you are surfing the net and just all around using the crap out of the phone battery life will be horrible. once the new smartphone phase wears out that battery life will come back up. On moderate use I get a day or better. on heavy use I get 4 to 7 hours maybe.

Big difference regarding the display technology between the two phones. It's the price you pay for the AMOLED.
Don't use auto brightness and keep the setting to its lowest if at all possible. An app called Screen Filter is helpful during night time reading.
Just make sure you let your battery drain until your phone shuts off and give it a full charge. You should be good from there.
Battery Dr is a good apparently. Just fyi

Battery not so good

I didn't use the note much, but it needs to charge each day. This is bad than tablet. Any software to save battery? I tried 'air plane mode' sofeware, but it also turns off phone after sleep.

What apps and widgets are you running? Have you gone through 2 or 3 full discharge/recharge cycles? There are apps out there that can detect if any app is consuming your battery but you will have to search the forums as I don't know of any first hand.
Also, which ROM are you using? When I was using Rocket Rom v22 with AbyssKernel 4.1, my Note would last more than a day on the same charge even with moderate use. Give that a try as it also really boosts performance.
I'm currently on Team Rocket Rom (ICS based) v5 but have not used it extensively to comment on battery yet. So far with 3 activesync email accounts (all push), some widgets running (weather, clock, etc.) and the Note sitting idle consume about 2-3% battery per hour. Will monitor this.
most smartphones ned to be charged every day, what battery life are you expecting to get ?
battery depends on the usage and applications you installed on the phone.
have you tried rooting already? usually custom roms have the best alternatives of extending your phone's battery and giving it an optimal performance.
Try to stop some bloatwares that your phone's loading up everytime it starts up(from rebooting)

I am using la2 rom. Here i attached an picture.
Geez... i personally feel that one day charge is reasonable especially with the juice required to drive the big display.
Anyway, Juice Defender premium is one app that has helped me, and may help you too.
Since you got Activesync, with the premium version of JD, you can customize app to be excluded from 'power saving', so that the inbox is up to date.
+1 for juicedefender.
Other tips that may not be obvious to first-time smartphone owners are:
1. Set your screen brightness to auto. You don't need the brightness cranked right up all the time.
2. Disable bluetooth and GPS if you're not using them. Juicedefender will do a pretty good job of managing your other radios.
3. If you've got email syncing set up on your phone, set it to check as rarely as you can put up with. Push email uses a LOT of battery life, and even a scheduled check can blaze through your battery if it's happening often enough.
4. If you've put on a custom ROM your phone may be reporting inaccurate battery stats. Give it a full charge, boot into clockwork recovery and wipe your battery stats. You'll find a few days after that your phone will start reporting more accurately.
Good luck, and if any of this was unclear feel free to ask further questions.

Try a later ROM to see if the same issue exists. I think you should instal rocket rom v22 - you'll be happy with performance and battery life based on your usage.
try to calibrate your battery as well... there are many apps out there that offers better battery calibration or you can do a manual calibration as well.
Give it some time and upgrade your ROM
I am getting great battery life. It runs for full day (24 hrs) with 30% of battery usage. though in a day i dont use it much, just 5 to 10 calls of around half an hour to 40 minutes.. data and gps always on.. screen brightness on auto...
My note running the OEM battery last me about 6 hrs.
Averages about 45mins talk time/day
About 50 SMS/day
Screen brightness set to 100
Checks email every 5 mins
Using a live wallpaper
Refreshes the daily weather using Accuweather every hr
Bluetooth always turned on
Battery Widget
Fancy Widget
ESPN scoreboard ticker widget refreshes
Twitter running all day
Facebook Widget syncing all day

^ This. Or better yet, just always set your brightness to the lowest brightness setting, 50% afaik. And use black/dark wallpapers and always turn on night mode (if applicable, especially when using your browser)
If in case you need to adjust the brightness, you don't have to go through the jungle of settings, just click notification bar and slide horizontally to change to your preferred brightness.
Jd is hit n miss will actually helping out. If your phone sleeps a lot jd is nice at keeping cell or wifi off if your like me and on it every 10 minutes then toggling data and other things can consume more juice. .... I have tried with and without on my tablets and phones and see no big difference depending on use.
Sent from my Ice Creamy Galaxy NOTE
I was pretty happy with my battery until two days ago. I use my note very little, for e-mail checking (which I pull manually) a few times a day, and to make two or three phone calls per day. I also text my kids occasionally. GPS and Bluetooth are off most of the time. Battery used to last me about two and a half days under these conditions, which seemed reasonable to me. All of a sudden, two days ago, I charged my battery, and after a full charge it drained 60% overnight. Thought that it was a fluke, so rebooted my phone, fully charged again, and the same thing (over half of the juice gone overnight) happened again. Battery stats tell me that Android OS were 100% responsible for overnight drainage. Any clues? I am on stock ROM, by the way.
Thank you.

Get a good app to check what is using the battery or keeping the phone awake. This last is the most likely.
Baddass Battery Monitor is my recommendation.
Not a single phone call, only used about 10 mins. after 21 hours only 11% left. Install Jd with 'balanced' option.

Thank you. I will give that a try.
Badass, got to love that name....
Ok, I used the Badass monitor to see what's going on. Once again, no phone usage, quick overnight battery drainage. Android OS 100% responsible, and the main power sucker is the Kernel (96%). Why is this happening? And, is there a remedy? I have changed nothing that would trigger this! My Note is still within the return window, so if there is anything wrong with it, I will return it.
Thanks again.

Badass Monitor is very useful, my note was drained by Dolphin Browser, it used 38% of battery. Seems like for this browser, if I only press home key to exit, It will keep running?
I think the reason the battery drain fast is we press 'home' key to return to main menu, that will keep a lot of apps run in the background.

Battery life significantly improved after installing Auto3G *honest*

Hooray yet another Battery thread!!
Feel free to shoot me down or close the thread and ban me if people find this not useful but I though I'd share..
I'm running AOKP PUB with Matrix 8.5 on my N4 and battery on WIFI was great but once I switched to H+/3G I would see an increase in wakelocks and hence battery drain. I'm sure more than a few people can relate to this problem..
after 9 hours from unplugging my phone, going to and from work and arriving back home I would have about 75-70% battery left with light use. Now after installing Auto3G from the play store I am going home with between 88-85% left which is making a massive difference to how long my device lasts,
Typically I'm getting 2 days standby and between 4-4.5 hours data/WIFI and at the weekends 5-5.5 hours on just WIFI.
The app simply turns data off when the screen is off then on again when you wake your phone up and it will turn data on every 30 minutes for 1 minute so your apps and accounts can sync. I have try apps like this before on other phones but this one has impressed me, plus its free! I haven't felt like I'm missing out on fresh content from my widgets or accounts because the syncing seems to actually work. You can set delays on when the data switches off too!
Anyways, here's the link..

Best thing I have done to draw out my battery life is to disable location services and then reboot. This alone has given me an extra hour of screen on time. I used to struggle to get to 3 hours and now I am getting over 4.

Are you doing it just to get max longevity or are you guys really struggling to make it through a day? Mine has been excellent, best battery life of a smartphone I have had since my old Windows Mobile days.
best and most visible boost for battery life is turning off the localisation and dimming the screen
I wasn't losing any sleep over battery life, my N4 has always lasted at least a day but I was a little disappointed with how long a charge was lasting me on H+/3G compared to WIFI. Now I have no complaints on either..
"When the user unlocks the phone, data will be enabled.
When user locks the phone, data will be disabled."
Sounds a lot like Juicedefender that's been around for a long time. I'm sure its good for some people, but kind of defeats the point of having a smartphone. Especially for me when most of my messaging is through Whatsapp / Facebook.
I used to use juice defender and I found that it became too complicated for its own good. You can change the syncing interval but I agree if you do you messaging through FB or WA then its probably not for you. I dont really use either often so the 30 minute cycle works well for me and maybe others..
Its not really defeating having a smartphone since its saving you battery when your not using you phone, its stupid to have the thing draining away when it's just in your pocket..
i'm using this app on my N4 too and have to confirm that works like a clock, simple and light but powerfull as let you choose when turn data on and for how many minutes, how much to wait before turn data off after shut down the screen and when to turn it on after the screen goes on...
if you want to make the battery to last longer it's a very good app...btw i think N4 has a decent battery that can drive you till the end of the day without problems
I just have a Tasker profile to run my data sync once every 2 hours or if I open up Gmail or anything else that needs to sync. This cuts down on the constant notifications when my phone is idle. I haven't noticed a big difference with leaving my phone on auto brightness of if I just turn down brightness manually.

Terrible battery life on GSM M7 - software issue?

I also posted this on the "htcone" subreddit:
I'm currently using CM 11, which is not yet stable on HTC One M7 GSM (currently on "snapshot"), and the battery life just kills me, so inefficient. I have an external 16,800 mAh battery and it does a good job eating through that too. 20% from that will give me 30% on the phone if the phone isn't powered all the way off -- that seems like a lot of usage (even if that external battery is used and only half that capacity now). I take measures to help my battery like auto brightness, turn off mobile data or wifi depending on what I'm using, or both to really save, I'm usually on silent, no bluetooth ever, location services always fully off unless I'm driving (rarely) etc. Just being in my pocket with a couple of hours or so total streaming music over LTE during the day the thing is under 20% after around 8-10 hours. A few days ago just a couple hours of music streaming (some downloaded some mobile data, not sure how much of each but still; this was not "screen on" time either) and an hour of web browsing ate 70% of it. It was 100% when I unplugged it around 6:30am and shy of 30% around 11am -- jeez!
I have been starting to think my battery is just worn out, I mean the phone is 2 years old (contract ends a week from tomorrow; it really is). But, what if it's the non-stable CM 11? Maybe a different ROM would help? I don't remember it being like this back on the stock ROM but it's been a while since then, and I remember being kinda frustrated with battery life every since I switched but I never got around to messing with this until now when I am even more irritated. I'm due for an upgrade, but squeezing some more life so I can wait another couple of months to see what unfolds (or change my mind entirely) would be great.
Can someone suggest some more efficient ROMs? I could handle Sense but I prefer AOSP -- whatever gets me more juice though. Or feel free to suggest other possible problems/solutions as well. In my power options in settings where it shows power usage, screen is always at the top with around 30%, so nothing jumps out there either. Thanks for any and all time!

I get the best battery life from Android 4.3 Sense 5.5
InsertCoin HTC ONE v8.1.3 >> http://insertcoin-roms.org/category/devices/one_m7/one_sense5/
It's also not real bad on AT&T Stock 5.12.502.2
I unplug the phone at 6AM and take it to work, normal use txt a few calls some web and emails and I have around 50% battery left when I get home at 3:30. On heavy use days I have about 30% when I get home. I should note my phone is also going on 20 months old.
