Energy Efficiency

I remember on my Wizard, that certain ROMs would drain the battery more quickly...there were actually radio patches to improve battery life, and they worked.
The DASH battery is problematic...it's a wonderful phone, crippled by an inadequate battery. I'm looking to extend its life, till I talk myself into an extended battery. (I've never been a fan of the "wart on its back" style of battery)
So, is there a ROM which is known for energy efficiency? I'm currently running Kavana.
Thanks for any guidance that can be provided.

Energy Rom Save battery
Kavana is good and i really liked it but, battery was still draining like the factory t-mobile Rom. I installed the Energy Rom and the battery last about 10% more and is a much nicer Rom.

i recomend getting a extended battery i got a 2200 mah it looks fat but its worth it

i believe i saw a thread on it already but since this one is open, can you reccomend a good extended non fat battery? (like a site that sells them)

megacapacity.com is a big seller

thanks, i wonder is the 1050ma battery is worth it.

I've heard this is a good battery, is the fattest you can get without having to fatten up the phone. http://www.seidioonline.com/product-p/basi13tmdhm.htm
I'm waiting for my battery to hit the crapper to get one.

I have this battery and it's good quality. I'd recommend them over the fat-ass ones that double the phone's size and screw up its attractive feel and profile.

I just finished my first full day with the Energy ROM and I can attest that it is more energy efficient than the Kavana ROM. Kinda' pretty, too, but I'm not sure where all the icons are, yet.
This is the first day in a while, that I didn't have to charge my phone mid-day.
NICE!
Now, I'll save up my pocket change and purchase an extended battery. A shame, since my brand new holster won't hold it, any more.
THANKS!

holy crap 1300ma and i thought the 1100 i saw on e bay was a good size. i just dont know if im comitted to the 40 bucks. gotta get a grip on how many days i can get on my dash on regular use.

Seidio 1300mah dash battery is the best purchase you could make
I really wouldn't give the 40$ price of the Seidio a second thought. It is well worth it if you do not want a unsightly buldge in your battery compartment, and want long battery life.
I don't use my phone much at all. I just browse the net a bit, make a few calls. I can usually grab the phone 7 am monday and it will last until friday 6pm. Before this with the standard battery it would last 7am till 3pm the next day. I don't know how I get almost 3 times the battery life but there you go.
If I stream music from the web it lasts about 4-5 hours. Or I listen to music stored on the flash almost all day and still have more than half the battery.

i think i might go with the 1100 off e bay for 12 dollars. i should be able to get three days off normal use. which is more than plenty.

Jeez...with normal LIGHT use, no bluetooth or wifi, and the regular battery, I'm lucky to get 8-10 hours of use. I admittedly live out in the country, but routinely have 3-4 bars of signal strength.
The battery is brand new, and head and shoulders above the original one, or I'd think it was a bad battery. Stock capacity, though.

Heres the truth yes some roms are drainers but the kavana on a S621 Pro is bomb for battery Life , you can overclock to 264 stable and the battery will last all day, in mind that you're not constintly on it, wifi batt life is 12 hours straight, set on 20 mins auto disconect and reconnect, you can spend some time through out the whole day on ur phones browsers on wifi, gprs i would imagen would last longer on our phones then wifi if u get a auto disconnector.., also huge tip, never charge your phone via USB, i wont go into why but this will kill your batteries Life.
U can turn off USB charging on the phone so syncing wont charge your phone, i recommand if u need to boost the battery use the wall charger!

1300 maH battery is the only battery you need for daily! use in My opinon.

Cheers

Amazing. No wifi, no bluetooth, and just AT&T cell phone use of 90 minutes or less in a day will kill my phone in under 10 hours.
That's with a fully charged, brand new, stock battery.
I live in a rural area, so maybe I'm having to use a higher radio power level...but even so, this battery life is just pathetic. This phone, I love. But, the battery life, I hate.
Apparently I've *got* to change to a higher mAh battery.

But nevercharge phone at night wth ur USB on ur pc, never do that.
Will surge the battery when the battery is fully charged, will just keep pumping the battery, and i recommand disabling the charging option when u sync.

Seido 3000mAh battery?

I'm wanting to get one, but I can't find ANY reviews online for it. Has anyone used it before?

Anyone at all?

3000mAh is scam.......should be good for about 2400 max

Had one for about 2 months now. I get about 24 hours of very heavy usage. Internet, numerous phone calls, texts, slingbox over 3G, and using power amp for hours on end will usually have me recharging after 24 hours. I could probably use it longer, but I hate to run my battery all the way down.

I have been considering an extended battery myself, but it seems all the higher quality brands (Japanese cells) are over $50. Not sure if I can justify such an expense over just having another regular battery to swap on the go.
If anyone finds a good deal on the brand name one, drop us a link.

Is this one that sticks out the back of the phone and needs a custom back cover so none of the regular cases work and your phone is twice as thick as stock??

Most extended batteries are like that.
Fortunately, most people who buy extended batteries don't care how it looks, don't buy custom cases to begin with, and don't care about thickness.
I need more battery life. Running Bionix 1.3 right now, and I'm constantly using my phone from about 6AM to 10PM every day with no time to charge it in between, and it's typically near the 5% mark by the end of the day, which I can't risk for too much longer.

Unless you are gaming just get an extra 1650 mah battery it is much more convenient. i had one but the weight and bulkiness was not worth to me. They do give a decent amount of use though.....

Yeaaah, I use mine a lot and it tends to die by 10 now, which means I"m getting about 16 hours of battery life. By all accounts, that's a good number, but it's just flat out not enough.

ag 3000mah gives me about 80% left after a 2 1/2 hours phone call which is pretty darn good, wich the phone call was with the screen off the whole time.

You can lower your brightness if it is not already at the lowest setting.

Unfortunately, the galaxy nexus has poor battery life. You could also try turning off data when you don't need it.

the screen is at lowest and it doesnt make sense turning of data if the problem is from screen right?

I'm having the exact same issue. Screen is totally eating up my battery life. It took 30 minutes for the battery to go down by like 10%. And the screen is 40% of the battery life issue.

Maybe I just don't use the screen as much as you, but I don't find this to be true for me. I find it has great battery life. I don't sit for hours with the screen on, but I do regularly text and check emails throughout the day, do a bit of web browsing, take some calls, and play some Angry Birds or other games in the evening. The screen is always at the top of the list for battery usage, but even on an extreme day I still have more than 30% battery left by the time I go to bed. I throw it on the charger and I'm ready to go again in the morning.
I disagree that the Galaxy Nexus has poor battery life, in general. I would argue that: all high-end phones have "poor" battery life because of all the things they do (especially 720p screens), your personal use of it consumes a lot of power and you could benefit from an extended battery, or you have a faulty device.

hi there, i do that exact same things with no games, so less usage but i get less than a day... i love the phone but the batery is just no working...

I don't understand why people don't get that when you have a screen that is 4.65'' it will destroy the battery life. My screen use is always at 60% or more but yet I still get good battery life. The screen is going to use the majority of your battery when compared to other things, that's just how it is.

sorry but thats not the point, when you pay 700 for a top phone, that is suposed to be the google experience to carry arround wiith you and you can only get 10 hours of battery time something went wrong in the process...

Most phones are $600 to $700, and name one 4g phone that will last more than 10 hours with moderate use and no extended battery, just not going to happen. You need to reset your expectations.

GN battery is giving lots of trouble, too. I picked up the phone from charge and it was 100% charged. ! hour of usage with 3g on. Usage includes 1 hours or music and reading of pdf books simultaniously and battery is dropped to 61%.

I think you should take a look at every other android phone that has come out with the same specs in the last year. Everything from the EVO 3d to the thunderbolt have their default battery's not last more than around 6-8 hours with constant use because of the screen & processors.
THis is why Verizon offered the extended batteries at a discounted rate right off the bat, because default batteries have never ever lasted that long in topof the line smartphones. FFS the new iphone 4s I've heard from a friend that their phones don't even last 24 hours.
I have a galaxy nexus, and mine has lasted... let me see.. one sec...1 day 3 hours and 25sec's with 35% left. (of course I have the extended battery) but here's the kicker: the extended battery has basically the same back as the regular phone does. so if they so desired, verizon could technically put out another extended battery just like all the rest of the phones, but they might not do that. I'm content with the battery life as it is almost identical as the droid X from which I came. The only difference is since I have a lot of un-updated apps for ice cream sandwich one of them is using "mediaserver" A LOT. I'm talking about that being the top of my battery draining with the screen being second. They both have taken ~20% with android OS itself taking 13, PlayerPro taking 13, and other random things like calls and txt msging taking ~10% each.
So I would suggest not trying to watch a lot of stuff on your phone while on battery, or don't expect your battery to survive long while watching stuff on that great screen

hymn thanks for the feedback so the only solution I see would be to go for a bigger battery. I'm from Portugal were could I buy one and whays the power?

If your screen usage is less than 50%, it be more worried about what else is killing your battery........

Got an extended battery...

...and its wicked (IMO..I've heard others not have good luck with them..)
Basically, I've gotten 22 hours of fairly heavy use.. web surfing, Facebook, gaming (order and chaos mostly) among other things....using auto-brightness.
Now that I have another battery...I'm going to unlock/root and get to work flashing like I did on my DX.
A question though.. If I use my extended battery exclusively, and keep my standard battery as backup... Will my standard slowly discharge over time not being plugged in? Idk much about batteries..
Thanks so much,

It will yes, expect it to loose approx 30% over a period of a year being idle. Nothing to worry about.

Oh okay. So popping it in once a month should keep it up then?
I just want to be sure I have one handy because I once got into a corner with my DX where I needed a full battery to .sbf and mine was half dead and wouldn't work...so I had to hunt a friend who also had a DX down to fix it lol. Just want to be sure I don't run into the same problem >.>

It will lose very little capacity not being used. He meant it will lose charge just sitting there. Just don't let it sit empty. Or at full charge.

You should be fine, lithium-ion batteries hold their charge pretty well. I've not actually tested them before, but try charging it to full and then booting up to see the charge in 28 days later, might be interesting to see.
I know my Nikon D7000 batteries hold their charge very well, I tend to leave one in the camera and discharge the one in the battery grip first and just use the battery for a month or so and swap them around. In the same sort of time, 28 days I can lose up to six percent this time of year, but I am going out everyday in temperatures as low as -12°C, so it's to be expected.

For this Id like to know some additional information... what widgets you have running. Stock or ROM and what kernel. As well as settings like display, sync timing etc.

If you want to store your LiIon battery it's best for the battery to have ~40% charge. The battery will age the slowest this way.
Do not store it at 100% or 0%. Check every 6 months and recharge to ~40% if necessary.

This also reinforces what I've heard. Store these type of batteries around 1/2 charge never full never empty.

[Q] Battery Life....I Just Don't Get It

Hello,
I know, I know, there are many threads on the battery issue. But I'm struggling just too hard with this. I've researched and read every thread on xda and other forums elsewhere to glean as many tips as possible which has certainly helped, but something just doesn't seem right.
Currently I'm using a battery saver app - Easy Battery - which does help considerably during idling and off-use periods - the DINC at least has some charge left to make a few calls and check voicemail when I'm finished on the job site and going home, but when actually using the device it seems like I can just watch the battery drain down - it's really disheartening.
My device details are below. I'm using the best performing kernel I've found after much trial and research. I've deleted about 10 - 14 resident system apps to improve performance - the DINC is as bareboned as it can get. Maybe I can delete a few others still.
I understand JB is more of a battery drain, but can it be this bad? After a full night's charge, I wake up and check my mail in bed, some quick online news browsing, looked at one or two video clips, 5-10 minutes each. I spent about 20 minutes on the phone. Looking at my screenshot, the battery's drained 40%, IN 37 MINUTES!!!
Also, some hours of the day the battery life seems better...? Sometimes I can perform general tasks on the phone, watch a few video clips, do some reading for an hour straight sitting over a pint and there seems to be comparatively little drain at all, certainly not 40% worth of battery drain in a half hour. I just don't get it.
Am I need of a new battery? Is there a super battery for the DINC? Should I be limiting the number of 'recent apps' in the Recent Apps switcher? Is there another Performance setting I'm overlooking? I/O scheduler setting?
Please, please, what can I do - any additional tips would be greatly appreciated. I love the DINC. For me, it's the perfect sized phone that I like, outside of any device functionality at all. Maybe I'm moving on though. Ugh.

if you have the original Dinc 1400 mah battery, maybe your battery just doesn;t hold a charge anymore.
what I do is I don;t even charge my batteries in the phone really. i find that when I charge the battery in the phone, the battery drains quicker. I bought an universal external charger and rotate a couple of 3500 mah batteries after running them down completely. I carry a spare with me if I need but usually my phone lasts into the next day.
you can get 3500 mah batteries for about 5$ or so on eBay(last I checked). the universal charger goes for 9.99 on NewEgg or Amazon. good investment

What I've done on CM10 to try to extend battery life:
Keep my screen locked at 25% brightness but can toggle into 100% or auto when necessary. On CM9 (before I was crack-flashing CM10) I played with auto-brightness levels that were discussed in this thread and they did help. 'Auto' is normally too bright for me, anyways.
Turned off background location reporting in Maps. This will neuter some things in Google Now, tho. You can see how often your phone "checks in" here.
I used SmartAssV2 on CM9 but went to interactive on CM10. No quantitative data that it helped battery life, but it passed my eyeball test after a week+ on both. My phone is flaky on under/overclock so I keep it at 245/998.
I leave 3G on, WIFI on, GPS off, BT off 99% of the time.

Hmm, great suggestions. An external charger(though I'd prefer not to be regularly opening the casing, I'll look into it); 3G radio off; locking brightness at 25%, toggling when necessary; background reporting off. I'll also keep experimenting with a governor and try a week on interactive. A really great kernels guide: http://forum.xda-developers.com/showthread.php?t=1369817.
I have a spare original battery so I've got that in and giving it a powered-off charge. See how that does on top of other adjustments.
BTW Both batteries I own are model BTR6300B 3.7VDC -- 1300mAh 4.81Whr - tekweezle mentioned a 1400mAh battery and other available batteries that are at 3500 mAh now - I guess I'm looking into new batteries as well -
cheers for the responses -

I recommend just getting a new battery on ebay for 5$. Also get juicedefender it doubles my battery life. Also try tiny/pons cm10 rom that has great battery life.

Definitely getting a new battery; I'm already using tiny's rom which continues Pons' CM10 rom builds. Really great -
cheers

Obviously, if you are using your phone non stop, you'd be lucky to get 6-8 hrs of usage. But the true indicator of what a phone does is how often you don't have to be attached to a wall outlet or hunting for one.
I don't know if others get similar results as me but this is more or less typical of me with light to moderate usage-checking email, Facebook, some Web browsing, occasional phone call or text message plus leaving my phone on overnight in stand by.
By the way, how I am on pons/tiny 12-9-12 and working well.

btw, this is the external battery charger I am using. awesome thing is that it charges at 600 mah so my 3500 mah batteries charge up in 4-5 hrs or so. since it has moving pins, you will be able to use this to charge any flat battery for any cell phone or camera you might buy in the future.
the SEIDO HTC EVO modified one I got on ebay charges at 500 mah and for some reason it takes 8-11 hours to charge a battery and I am finding out now that it doesn;t even charge them completely even when it thinks they are completely charged. i take a battery that is charged in this and put it in my other charger and still needs charging of about 10 percent!

I get something similar, probably a little worse, in send/recv about 50-100 texts a day and checking 2 gmail and 1 exchange account constantly. My battery does tank when I'm actively using the phone and really all I can do there is manage the brightness of the screen. I've been doing my tweaking to try to increase battery life when I'm not using the phone. In 7 hours last night it only went down 3%. When I first started using JB it was 10-12% a night.

Great, great info - love these forums, and I love android!
tekweezle - could you tell me exactly which 3500 mah battery you're using with your DINC? Also - no issues whatsoever with the pons/tiny 12-9-12? I thought I saw a few things reported with the 11-28-12 and stayed away from it, staying with the 11-25-12.
cheers!

i have an expensive SEIDO battery that I bought from Amazon in the beginning for about 59$. Never thought the capacity was all that great till i found out that my battery wasn;t even being charged completely. not really worth the money but at the time, it was all that was available
