[Sug] Future Rom Development - G1 Android Development

I'm sorry to post here but I think it's the best way to catch the proper eyes, and xda tends to be so messy can you really blame me?
To be blunt and not waste time.
When developing your next ROM could you please disable the LED flash for a battery under 15% or whatever amount it is.
I think it cuts the battery life in half when flashing every second.
It's unnecessary and annoying.
Please and thank you.

does that tiny led pull that much power?

LEDs are very efficient, no need do switch it off.

You thinking it is annoying is reason enough for devs to cut it out of their rom?

thank you very

let me use this post to propose an usability enhancement (under my point of view):
I am not questioning the battery expenditure of the led, far from it, but the frenetic red blinking does get on the way of my other notifications.
Example:
- receive a SMS on <15% battery -> the custom _yourcolor_ led does not flash, getting replaced by the low battery one.
If one could, for instance, display both, it would be perfect!
Just trying to make this thread productive, cheers!

have you tried buying always flash from the market. it allows your custom led to flash whenever you get a notification, even if its on charge.

It works fantastically when on charge, however does not override the 'low battery' flash when not on charge

"Typical LEDs are designed to operate with no more than 30–60 milliwatts [mW] of electrical power."
it would take about 10-17 hours of the LED on constantly (just the LED) to drain the battery...
it isnt even a constant ON for each second - it uses PWM to minimize the power it consumes (thus the reason it isnt very bright)
so in real terms....that little light flashing is as detrimental to your battery life as a fly hitting a 747s window when its going full pelt (ie. not)
EDIT: miscalculation - looks more like 40-52 hours

I think it cuts the battery life in half when flashing every second.

its an LED, not a xenon camera flash

[Q] How can you make the battery last longer??

Is there a tweak out there that stops the stupid battery from guzzling? Im tired of charing it constantly and I swear it takes hours and hours to charge it back to full power. The thing cant last longer than a day without loosing power I cant stand it. Whats making it use all that power? I thought maybe if I switch wireless it would help but I didnt notice a difference.
I can get 2 days out of my battery.
I let it drain to 1% and then stick it on charge over night. When i get up the battery will be at 100% and then 30 minutes later down to 90% but it settles down after that.
I do not have wifi and bluetooth on all the time, just when I need to.

I don't understand people telling battery lost for 2 days..... even if we keep phone idle it will lose power in 24 hrs i believe....try like this try to use ROM with out manila & with manila once you will know the difference other than that there is some tips to save battery in Energy ROM thread in 3 rd 0r 4th post ..
4 days normal usage.
Manila2, GSM
15 minutes call, 6~10 text message, sync exchange, 30 minute ebook reading per day
If I build rom myself from the kitchen. It usually runs for 2-3 days.
However, in most cases when I try decent cooked ROM, for example, Energy - battery drains in about 5 hours. That's been the case with other cooked roms as well.
I suspect that some popular configuration change done by cooks causes battery to drain in certain environments. Would be nice to find out which change is that.
Processes and services often place a strain on the life of the battery; add to the mix a buggy service or application that further shortens battery life and one has an unusable device.
Another habit that can shorten Li-ON battery life is full discharges - near 0%. One of the members put out a thread a while back on research he/she had done on batteries - worth the read if you haven't already.
Cheers,

I just had the same experience, cooked for the first time and my battery was better than it has ever been!
Since then I have flashed to RRE 21731 6.3 and it seems my battery has stayed the same (Brilliant, 2 Days no problem).
The only thing ive done differently is I have used the new UK Voda rom as my Stock Rom that i flash before flashing custom, and i believe this may have something to do with it...What, I don't Know.
I also believe changing the Radio After a flash can affect battery life, I always try to flash a new radio before a Custom rom.
I have wondered for some time wether the European Touch Pro is slightly different to the US Fuze in its hardware, Since most Cooked Roms are configured for the Fuze maybe that is what it is?
maybe we will find out..One Day
turn off 3G and you will get much better battery.
Get a Blackberry Bold. My phone has been on for 2 days, sent around 150 texts, got in 150, I'm at 85%

That will ****-up your battery, you should never let it drain to 1%, just charge it when you have the time, preferably before it drains to about 20%.
I guess it all depends on the eye of the beholder, I come from the Diamond part of XDA, and we are lucky to get 24 hours on the Diam.
I was happpyyyyy with my new TP battery life -compared to Diam that is-
But ya, turning of 3g and being picky about processes and back light helps.
Greets to all.
Search the development and Hacking thread for Windows Long Life/save your gonads. Chainfire is developing a neat application to automatically switch from 3G when not needed. I tried an early version and it seemed to significantly increase my battery life.
Check my sig....it tells you how to deal with Li-ion batteries...
battery stuff on my site
Check out chapter 17. I cover this pretty thoroughly.

An app that may help is Advanced Task manager, it has a widget to end all running processes/tasks which i tap before putting mine to sleep about 1000+ times a day it seems. go in and exclude ones you may want to exclude always and then its as simple as 1 click. as everyone else said, no gps,wifi,3g when not 100% necessary. also, get widget "toggle disply" from rounded labs and keep your screen completely dim (not like you can't see it...), being able to make it bright when you step outdoors. Also, toggle backlight app for root users keeps the pesky keyboard backlight off when you don't want it on (suggest making keyboard shortcut for quick toggle). last but not least because i'm sure theres plenty more, but yesterday i switched to cyanogen's newest stable ROM and it seems to be much more effective than any other i have tried in the means of saving battery life. had wifi on after a 98% charge for about an hour and a half (30mn usage) and it only went down to 91%... wow. "and that's all, i have to say, about tha-aat"- Forrest Gump
Firstly I don't think this is the right sub-forum for this question since it's not a specific ROM question.
Secondly, try nueDynamicClock, if you use the right settings, you'll extend your batt life by at least 1/2 a day if not more.

It's really very simple. Flash an awesome rom, and the battery burns and burns. Flash a rom you hate, and the battery lasts forever. Don't over-think it.
hi guys.
i was eager to start up this discussion and am glad to find it here itself.
even am really finiky about battery.
tried alot of thing but cudnt find any spcl tweaks.
though i came across some registries from advanced config and other wise also but they seem to be more worse.
;IMPROVE BATTERY PERFORMANCE
[HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms]
“DisablePowerManagement”=dword:0
[HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms]
“DisablePowerManagement”=dword:0
[HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms]
“DisablePowerManagement”=dword:0
[HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms]
“DisablePowerManagement”=dword:0
when i use these tweaks the power consumption of my rom reached to 4.112 volts(as per power detect) which otherwise without these tweaks is 3.992 at startup.
more power consumption i guess means less battery i guess.
and even if its not still these tweaks as per my usage show bad results.
why so?
and arnt there spcl application which can detect the packages which might consume more battery, as i have over 50 packages in my rom and it'll hell to check which eats more.
Some tweaks I do
I have also found for me that disabling these things in advanced config also helps.
Performances
> File System cache: Disabled
> File System filter cache: Disabled
> Glyph Cache: 32kb (advised) I'm not sure if disabling this one is a good idea. I like having a little bit of glyph cache on my device.
Light senor
> Light sensor polling: Disabled.
*Note: If you want to still have light sensor on (this means the auto backlight feature) I would set the:
> Light sensor polling interval: 2000. This will make it poll every 2 seconds instead of every .2 seconds. I would even try setting it to 5000.
The backlight will make a huge difference on how long you battery will last. The brighter it is the more the battery needs to light up that screen. If you turn off the polling all together it will make the battery last longer.
Also running fancy UI apps will also deplete the battery more. Just common sense really as another poster alluded to earlier. The more things you have running and sucking up memory the more battery it will consume. If you disable TF3D or other apps such as this you will get your battery to last longer. Given that these devices are meant to have these types of programs on them you will have to weigh the options of how much you really want to "tone down" your devices to get the most out of your battery.
Also different radios will cause you battery to last longer. I suggest to everybody that they try different radios to see which ones last longer. Also people who live on the edge of 3G and EDGE area will cause the battery to drain faster as it constantly switches in and out of 3G coverage.
WMLongLife is a great app if you don't need 3G while you phone is just sitting in you pocket. It works great for me and when I want to use 3G I simply launch opera and the program will automatically enable 3G once again.
There are many things that you can do to improve your battery life. I encourage everybody to find what is best for them given what they use there device for and try and test things out. The best way to tell which works best for you is to simply try it out for yourself.
**NOTE** I also set all ROMs that I flash with a page pool of 0. I don't know if this has any real effect on battery life but it does seem to make my battery last a little bit longer. Not sure if this is a placebo affect though.

Normal Battery Drain?

So after 2 hours and 3 minutes...my battery is at 25% ...since starting to write this message it has dropped 3%. The display is taking up 80% of use. Screen brightness is about a centimeter from the far left side. Screen has been on about 90% of the time...however...after only 2 hours and now at 23%...I'm a little concerned. Any suggestions?

I does pull less power but having it on all the time while at work will still drain your battery pretty quickly and why want you have this on all the time?

It was more of a test to see how long it lasts with the screen on. I am a little concerned though because lets say I'm sitting in an airport or on a plane watching a movie(I travel for business). My old Droid X could get me through that. But I'm thinking that it wouldn't be an option if my battery is dieing after 2 1/2 hours with the screen on.
Coming from the droid x, kernels weren't an option so I don't know much about them. Would an enhanced kernel be able to help with this drain or am I SOL?
I'm having battery issues as well and hoping someone can help. I heard people are getting great battery life with this device, but so far mine is about the same as the thunderbolt was. My charge says its mostly the display taking up the battery life, but I've done all I can to help this. My screen time out is at 15 seconds and my brightness is at about 20%. I am running ADW EX but I wouldn't think that would cause this. Anyone have any other ideas?

The screen does use less power, but a significant amount of the power savings comes from displaying black, as black uses no power on the display, where it does for LCD displays. For me, the Display is usually responsible for 65-80% of the power drain, so your usage seems somewhat normal. Custom kernels can help with drain some, but what can be tweaked with a kernel won't help with the display draining the battery.

Potential Solutions?
So besides reducing screen timeout to minimum, turning off background data, and cutting off literally every single connection (wifi, BT, 3g/4g, gps, everything) except 1x for calls and texts, removing bloat, are there ANY other measures one could take to enhance the stock battery life? I find myself talking on the phone for roughly 1hr per day but I do send nearly 500 text messages daily thus my screen is on a good portion of the time. I have to charge this phone twice per day at 2.5hrs per charge, it sits near an outlet for 5 hours a day heh... In fact even though I live in a 4g area I can't really use that feature because it beast's the battery down like a ravenous monster even with ALL other services disabled, not making calls, just texting and syncing email.
Task killers:
To me the task killing programs (ATK, ATM, etc) do actually kill background tasks and sometimes even services depending on your particular settings but since they just restart automatically does it not use MORE cpu time to re-run the damn things than just leaving them in the first place?
Launchers:
I have found no significant difference whatsoever between battery life under TouchWiz and LauncherPro. If anything its worse with LP because of the nifty graphical effects.
Kernels:
I'm pretty sure I read somewhere people were experiencing better life with the v4 voodoo kernel however I've noticed no difference at all there either with regard to battery life.
Running the phone with no services and charging it twice daily seems fairly extreme, eh? The extended battery is tempting, but one thing that attracted me to this device was its slim design. I don't care if its a little thicker and all but that ext battery is a freaking monster! Forget having a case with it too, at least for now.
Thoughts, suggestions?

500 text/day? Wow, you must be under 20 with thumbs/pointing fingers of steel! If your average text message takes 30 seconds, your screen is on and the screen/keyscan interrupts are running full bore about 4.5 hours a day just texting...when do you have time for Angry Birds?
Maybe a thin white text on black background for your screen theme? Just kidding (sort of), but I'm amazed at the talk/text times; gettin old, I guess!

Seems like this explains while some report great battery and others terrible times...depends on what somebody considers "normal" to "light" usage and while some consider "texting" light usage if the screen is on black text on white background the whole day, there goes the battery stats. Same with screen on sitting doing nothing (maybe displaying time)...
Should "Battery Life" be normalized or adjusted something similar to "Time Between Charges" divided by ("Time Screen Display is On" times "percent White pixel counts")? Are there any battery stats / device stats / display stats that can help figuring out a "Battery Life Index"?
Sorry for the random thoughts....

Actually I've been keeping track and the screen is on 3-4 hours per day, plus the haptic feedback, interrupts, etc. Doesn't take me anywhere near 30s to send a text message, few seconds TOPS for most of them and I never said it was light usage haha. Just asked if anyone knows of other measures I did not list which I may employ to extend it more.

The vooodoo kernel will help a bit as it uses a much more optimized file system so your phone will spend less time cache thrashing and reading/writing large downloads.
Essentially though it is down to how long your screen is on and how many accounts you have syncing in the background, also if you don't need full 1ghz for texting/calling smoothly then use setcpu with an ondemand or interactive type scheduler and set the max to like 700-800mhz...

This....
BUT i will say that the battery life on this phone takes a great big dump on the TB`s battery, now thats a bad battery life, i would consider myslef a heavy user i make around and receive around 100 calls a day, around 100 emails and around 75-125 texts per 8 hour working day
i can get through my day putting my charge on charge ONCE for around 30 mins, my thunderbolt had to be plugged in most times, 2-3 hours max for total battery death ( 3 hours is extreme generous, was more like 2 hours ), i carried 3 batteries with my thunderbolt.
The charge for me is great, on a par with my old galaxy S for battery life, if only they coukd give me iPhone battery life, for as much as people dont like the iPhone, it sure does sip the juice
Myphone ie ed2 stock, no rooted.....YET im waiting for a stable CWM

Battery life horrible? Try this!!

For all you guys who need the edge on battery, and dont need alot of screen brightness, like me, then try out this app on the play store called screen filter. (I am not affiliated with this in any way, I just like the way it works). What it does is apply a "film" over your screen going even lower than android screen brightness. Perfect for office setting (like me), at night when brightness is too much (laying in bed playing a game), or where bright lights might not be wanted (movie theater, work, etc...). I personally love it, I use it usually at 75% with the android brightness off, and everything is still visible, just that extra kick of brightness is gone. Sometimes I go down to 50%, but that gets me seeing my reflection just as well as the screen itself...
It also helps to keep out them creepers that try to look at your screen while sending private texts, pics, etc... Helps keep wandering eyes off of the fancy 4.8 super AMOLED display!
You can add widgets to custom brightness settings to suit yourself, I have 4 right on one of my screens that I use frequently!
I recommend this app to anyone and everyone!
It wont let me post links, but if you search "screen filter" it should be the first app. The logo has a white rectangle outlined in orange with a grey circle in the corner. Not too hard to find at all.
I'm almost positive that screen filter won't increase battery life. I think the phone basically "thinks" its still at a higher brightness than what you see, so it really doesn't improve battery life. I may be wrong though but I remember seeing that when I used it on my droid x.

OLED pixels produce their own light (that is, without a separate backlight). Colors are made darker by dimming pixels. If the app makes what's being displayed on the screen darker, it should be helping battery life. The same reasoning applies to saving juice with dark backgrounds and inverted apps. It just only works on OLED screens and not backlit screen types.
Okay. I wasn't sure if I remembered correctly. Thanks!

Lux Auto Brightness works a little better, in my opinion. It can go less than the screen's brightness without the filter look.
Hi guys,
A friends uses auto brightness, and only speaks ~ 20 minutes / day. A few browsing, reading e-mails, games, just got him at 2 days of usage. Not bad in my oppinion, but certainly they should have improved the battery.
To me it seems like the battery life is longer. My first week of use around 9 or so it would be in the red, but using it throughout the day, at 9 tonight it sits at 37%. Yes it will vary depending on use, but mine has been on battery 15h 30m and screen is only 18%. Cell standby is 30%, and chrome and facebook are each 11%. Everything else is quite small compared to those main apps used.
It seems to me it is helping, but it may not idk. I will continue to use it unless I run into a major issue with it.

+1 to Lux. Set your own brightness levels for various light levels. It can make the brightness very low, almost not visible.

I would be happy to get 2 days of usage... I probably could get 1 and a quarter, but I charge mine every night to be safe. Really varies on how much I use it during the day. Some nights I plug it in with 10% others with 50%... I know its not the best for the battery, but I just plan on getting a new one when this one takes a crap. I have a feeling this phone will be around long enough that the option will still be available

What I would like is for my battery to last just *ONE* day. It doesn't do that. I don't mind charging it every night, but I'd prefer it last the day without me having to either charge it or switch batteries.

[Q] HTC One XL Battery Life

I am curious about the battery in the one x, and especially the habits of consumption.
I have been around the block with android development. I had a captivate before this, and managed to get great battery life out of that! That was much more simple however. Flash a rom, cycle the power, cycle, cycle, cycle. Then you're good to go.
I feel like the way that the one x deals with the battery is different, more advanced. Some bootloader level software that is untouched, like the hardware keys and whatnot.
My battery has been hit and miss to say the LEAST. I use BBS to take care of wakelocks, keep data and gps usage to a minimum (my regular use), and I charge my battery when the phone is dead up to 100%.
The back of my one x gets very very hot sometimes. This varies rom to rom. Started with stock sense ICS, took the OTA jelly update, now I am rooted, s-off, and on cyanogenmod 10.2 nightlies (which run insanely well btw). The issue is the same. It reacts the same, and is just as unpredictable. I have read about this, and know its a hardware issue, but I am still curious about it, as I have heard SO many different things. I am usually able to quickly curb the issue by turning on airplane mode, or turning my phone off (for a while, as rebooting doesnt seem to help).
In passing, I also read something about "HTC Charge Mode". I have read forum posts where people say things like "hold both volume keys and the power button for two minutes, this with re-calibrate the battery circuit." There are so many combinations of keys and timings that people talk about that I can't help but believe that it is all garbage.
The heating up is typically caused by camera usage, data (radio, I assume) usage, games (temple run 2, gyro), and sometimes even spotify (offline playlists). Wifi seems ok, not too much of a contributor. When I was on stock sense jellybean, I was able to fix a lot of the heating up by turning off "google location services".
The weirdest part is that if I feel the phone warming up, I can go into airplane mode like I said, and its fine. If I keep perpetuating it, however, it gets very, very hot. Hot enough, im sure, to melt soldered connections. I turn on airplane mode, and it doesnt get much better. This is when I have to turn it off. Sometimes it hurts my leg in my pocket if I absentmindedly leave data on.
So I want to know -
1) what is the deal with the battery on the one x
2) can I cycle the power like I could on my captivate?
3) if you know anything I don't about the heating up issue, please share
Thank you so much for reading! I look forward to the possible feedback!
TL;DR - please read the post! I'd really appreciate it!
One thing I do know is that after doing your initial few charge cycles when flashing a ROM, it's better to not actually let the battery level get too low before charging. I read an article by a battery scientist, he stated that continual full discharging of the battery will decrease the long term battery life. So, it's best to do top-up charges from ~40% to full charge. Obviously you can disregard this when doing your initial charge cycles.
Some of these phones heat up more than others. Having the phone in your pocket or any enclosed space for an extended period of time will encourage it to heat up. I can't remember the technical term, but it's a combination of there not being enough air flow around the device to facilitate its cooling down, and nowhere for the heat to go. So it just gets worse.
So knowing that, there are some steps you can take to mitigate the heat, even if only in a minor way.

[Q] Any Tips for Reducing Battery Loss When In Pocket?

In my 8 hour day, I really only physically use my phone maybe 2-3 hours total.
I'll send a text, be at 90%, leave in pocket for 2 hours, and all of a sudden 79%. Urg!! I understand it's essentially inevitable, but can it be improved?
Sure, there are several obvious things;
-Turn Data/Wifi off during sleep
-Turn sync off
-Turn device... off!
But personally I prefer Data/Wifi on so my phone is always readily available if I need to do something fast! Turning it off would be even worse for me.. and I have sync slimmed down to almost nothing.
What else is there I can do?
--- If the answer is simply.. "nothing" that's fine, please let me know if that's the case ^_^
I've owned many Android devices and iPhones, sometimes both at the same time, and honestly, every iPhone I've had does an amazing job at reducing battery loss while the phone isn't in use.
If you've clicked this thread, please leave your opinion, whatever it may be! Thanks ^_^
Go into your settings and see what's draining your battery.

Apart from the obvious (dimming your screen), you can decrease your screen's drain on your battery by using a "dark" theme as much as possible. Your Note 4 has an AMOLED screen, which is basically millions of tiny LEDs that make up the pixels. Unlike an LCD or TFT screen, which is back-lit regardless of color, AMOLED screens have the pixels individually lit as needed. So darker colors don't need as much energy, and black is basically "off".
Also, it sounds like maybe your screen is waking in your pocket because the power or home button keeps getting pressed. Perhaps try a different method of carrying it, or a (different) case or something.
