    Using CM7 122-1024 Mhz Interactive governor.

    Get More Battery Life

    Getting the idle drain down is the most important because the phone spends most of the time idling. During use it can pull a lot of power (expect 10-15%/hr drain when in use), but that's something that just comes with using a smartphone.

    Here are my suggested settings, prioritized from what I believe to have the most impact on battery life to the least.

    Turn off 3G, wifi, BT, GPS unless needed by toggling in status bar. Or use an app like Juice Defender to automatically turn them on briefly every 0.5/1/2 hours.

    In CM7 settings (or quick settings app) I setup the notification bar to toggle each with 2 quick swipe actions, so it's very convenient. 3G data generally uses more power than wifi. But having both on, even when no data is transferred still drains a bit more than having them off. Also having them off prevents badly written apps from unintentionally transferring data. To get immediate msgs through, I set SMS notifications for FB messages, Google Voice SMS forwarding, or even email notification from certain people. Forwarding email to <yournumber>@vmobl.com will send it through SMS. SMS runs off the cellular phone network instead of the more battery intensive 3G data network. NOTE: MMS requires 3G data, but people could just send them via email.

    Minimize running widgets & app services, instead use the mobile web site through Opera Mobile browser for example.

    Instead of installing different apps like FB, traffic, weather, gasbuddy, have those sites bookmarked. Using Opera Mobile Turbo technology also saves on transferring data (it compresses webpages on remote server before sending).

    Airplane mode for weak/no signal areas, sleep, & work hours

    A cell phone searching for signals can drain the battery pretty quickly. Not only does it transmit at maximum power, but it does it frequently to try to re-establish a connection with a tower. So if you know you'll be in a weak/no signal area for a while, just disable it.

    If you don't want to be interrupted during certain hours of the day, might as well turn off the radio too. If there are no rogue apps running the background, idling even with a cell signal should be less than 1%/hr. In the graph above, notice airplane mode & cell idle times have about the same slope.

    Lowest brightness in most indoor settings. The screen uses a lot of power when on, so turn it off if you're done (instead of waiting for it to timeout).

    Disable Data sync, transition animations, sounds, vibrations

    Whenever the CPU does extra processing, it requires higher frequency CPU, so getting rid of the eye candy focuses the processing to just the important tasks. Audible sounds & haptic feedback use extra battery power too. Motors (for vibration) typically use a lot of power compared to audio & CPU processes.

    122/245 - 1024 Mhz Interactive Governor CPU settings (Root required)

    Power consumption formula is P ~ f * V^2 (where f is frequency, V is voltage). Voltage has the highest impact in the formula, so undervolting (root required) has the biggest impact, and it depends on what your processor is able to handle. Overclocking has little benefit in terms of every day use, and drains more battery.

    I prefer the tried & simple Interactive governor, unlike InteractiveX and some more recent smartass governors, it doens't lock the freq to the min value when screen is off (i.e. playing music), but ramps up quickly when needed.

    Remove bloatware. Don't run task killers, freeze or uninstall bad apps (Root required)

    Some apps may be waking up the CPU in the background wither accidentally or without any good reason. Task killers also frequently keep the system awake to monitor what processes to kill.

    Recommended apps for monitoring & checking battery usage.

    Current Widget - displays & plots current usage in mA every 60 seconds.
    CPU Spy - Allows monitoring of whether deep sleep state is reached when screen is off.
    IncrediControl (Kernel Support Required) - Allows setting undervolt values.
    BetteryBatteryStats - Allows tracking down things that keep wakelocks on the system.
    StabilityTest - To test the stability of the system at certain undervolted values.

    Charging a Battery

    [​IMG]
    Charging through an AC socket is faster than USB. Both enter trickle charge at about 90%, and then tapers off even after 100% is reached. Here's a graph of an actual charging session off a wall socket, monitored using Current Widget. Unless you wait the extra 1-2 hours to trickle charge fully, above 90% doesn't actually hold very well (it drains quicker than below 90% if charged to 100%)

    Li-Ion batteries do not like to be in extremely drained nor extremely charged states. So try to minimize them, but you may need to give it a stretch (by draining all the way down, or leave on charger an hour after 100%) to calibrate the battery meter. For everyday use, just charge it when it drops below 30%, then pull off charger after 90%. More interesting info at Battery University

    Battery Meter Lags

    The battery meter may not be accurate when flashing a new ROM or when there's heavy drain and it hasn't had time to re-adjust, so it lags a bit. Usually it needs a full discharge-charge cycle to become accurate.

    CPU frequency & Battery (Root Required)

    [​IMG]
    1st Section was running Stability Test app at 1024 Mhz, 2nd section at 245 Mhz, 3rd section at 122 Mhz. 4th section is idle at 245 Mhz, 5th section is idle at 122 Mhz. So there is a slight difference between IDLING at a certain frequency and loaded at those frequencies. Modern CPU's have a 'no-op' command that gets executed when it doesn't have anything to do which saves more power than executing instructions at the same frequency.

    Whats the app to undervolt or did I miss it?

    Thanks for the reminder, I added it to the post. It's IncrediControl and requires rooting & a kernel that supports undervolting.

    I find I can get just over a month on my phone if I turn it off and take out the battery and keep it in the refrigerator and wrap the phone in a soft cloth.

    Honestly. With Tickerguy's CM7 mod, moderate use, and keeping 3G on, reading emails, answering calls, and checking the web a bit at work, I find I get around 50-60% drain after a 16 hour day. That's completely acceptable. The phone is meant to be used.

    I think that all of these "tricks" of turning off the usefulness of the phone kinda defeats the purpose of having the phone.:)

    I don't feel like I'm sacrificing anything. It's still convenient to use and I have the power of a supercomputer in my pocket with access to the world's information at my fingertips. Take whatever you want from it, and it's good to know in case of a special situation where you don't have a charger handy, but still want to be able to receive phone calls/SMS. Just because a phone has all the whistles & bells doesn't mean it needs to be all used or none at all.

    Oh, I agree. But it at least has to be functional as a phone. I'd extend that as "a communication device", meaning texts and emails should work too. Everything else - Yes, you're right, turn it off unless you need it. I have a friend who travels with four batteries for his smart phone (not a Triumph) and insists on leaving wifi on (even when there's no signal to be had) and gps (even when indoors). That seems kinda loony to me.

    I personally prefer not to be interrupted by email notifications all the time (interrupts the flow of what I'm doing), but if I'm waiting for an important email, I can always go to my account & set up a filter to forward it via SMS. Then I can turn on 3G on the phone and reply (or even reply through SMS).
  8. my father owns a Windows Phone 7 device on ATT. he had a smartphone plan but didnt use it so went to calling and texting only.

    I've seen that phone go from a day of use with 3G, to having the 3G off 24/7 and him getting a week or so out of it.

    whenever I visit, he always says his charger is lost. which means his phones been on for days without charging.

    Kind of sad though, I updated it to mango, played with it on wifi, liked it a lot. but it will never be used to its potential.

    on my triumph on the other hand, I bought 2 extra batteries and dont leave home without all of them being fully charged. as my phone will die in 4 hours with the kind of use I put it through. need the data and GPS for work related stuff

    Oh I still use my phone plenty, I like the peace of mind that it's not draining like crazy just sitting there. Some of the things I do with my phone are: Take notes & sync them online, calendar reminders, alarm clock, read pdf's, ebooks, barcode scanner, pandora, guitar tuner, sudoku, ftp file server, GPS navigation, maps, VPN keycode generator, watch videos, VoiP calling, google voice integration, take pictures/videos, & browse the web. Not all of them in one day, but often enough.

    So with the settings above I get the best of both worlds, battery life of a feature phone, and the power of a smartphone when I want it.

    Thanks for the settings Whyzor. The battery life on stock is pretty horrid. I loaded CM7 to see if it would improve, and it did. But I was still dealing with losing 5%-10% an hour idling. So now I am following your guidance and hopefully I can get a full days use out of this thing without worrying about finding a charger.

    Smartphones operate on a sort of spectrum. On one end you could put battery life, on the other all those options like wifi/3g/sync and all that. If you want great battery life you can't have those on all the time. If you want those on all the time, you won't get great battery life. It is best to find the compromise that works best for you and what you want most out of your phone.

    This guide is just letting people know what they could do to make the battery life better. It is by no means necessary to do everything listed.

    It's to bad that we have to resort to such measures to make our phones last more than half a day. I blink and can see the batt life lose a %age point LOL. Even running the latest Tickerguy, the cheap GPS, single band cell radio and overheat issues all play a factor in this phones shameful battery performance. If I had paid for it out of my own pocket I would've returned it by now. I've tried all the automated tricks like Juice Defender (free) and Battery Defender, undervolting and the only thing that works for me is to manually turn off the Wifi/3g when I know that I won't be using it for a long period of time on the weekends. I HATE doing this because I like to receive my notifications in real time. When I turn it back on after it's been off for a while I get flooded with messages and it's annoying. During the weekdays I need realtime access to my email since I get my corporate IT email via Touchdown so the battery life really takes a hit during the workday.

    It also sucks that the highest rated battery we can get for this hog is only 1600ma....why Moto decided to throw in such a paltry battery in it is beyond me...1380ma...really Moto? UGH!!! Come'n Seidio...gives us a 2.5kma battery please!!!!!!

    Like I said above every smartphone has that spectrum (granted they may be slightly different per phone/user/location) and you have to decide what you want, better battery or instant notifications. I don't know of a phone out there that you can use heavily all day long and never run out of battery.

    Just a question Prey, and please don't take it the wrong way. But if you need a phone for your work email, why don't they provide you with one? A company shouldn't demand that you buy a phone for that on your own with no reimbursement. Are you on the road a lot or in an office? Could you leave all that stuff on and just use a charger now and then? :confused: I am not trying but into your business here, just asking questions, maybe I can help figure out some better options for you.

    I plunked down the few bucks to get Juice Defender Ultimate (better than the free version!), and I get my notifications every 15 minutes. It is rare that I am bombarded with so much stuff in that short of a time window. You can even set different schedules for work hours, evening, and night time with the Ultimate version.

    I just want to say it is fine if people have their own opinions and everything about the battery life of this phone, but since this is a sticky please keep the stuff posted in the thread related to the suggestions or questions you have about it. It is fine to state your own opinion about the battery life, but it might be better to put that in it's own post. :)

    I didn't pay for the phone, my company did, which is why I haven't returned it LOL I did get the phone at launch so I'm thinking that I may have a POS unit and that swapping it out with another that was hopefully built at a later date would perform better. I have Best Buy's insurance on it so that's an option.

    My annoyance with the battery life is more on the weekends when I'm not in the office and am out and about with the family a lot and don't have access to a charger. I've resorted to carrying the OEM battery around in my camera bag for emergencies, which has happened more than once LOL

    With all the money I've saved the last week with Google's 10c sale in the Android Market, I may just pony up the cash and get JD Ultimate and just add Touchdown/Gmail to the Whitelist so that it receives emails in real time and all other apps on schedule. That should help tremendously since I'm a Facebook/Twitter/4Square whore and get tons of notifications so yes, if the phone has no data for like an hour, I get slammed with notifications when it goes back online.

    Ah, well would something like the OV be better for your job? I don't think it really gets much better battery life. My wife has that phone and uses it less so it lasts longer, but maybe it gets better battery life than I think. Also, just curious, what is your typical time without signal? Carrying around another battery seems like a reasonable solution. You get everything when you want it, and have another battery there when you run into that issue. Ideally you wouldn't need that, but most smartphones I have seen will have the same exact issue if all those settings are left on. I have co-workers that get much worse battery life on evo's and iphones.

    Even with it's better build quality, I could never downgrade to the OV's small screen after using the Triumph...I'd rather deal with the poor battery life before I did that LOL The OV, with Battery Defender lasts for days....it's pretty impressive. I have her OV running Cyanogen as well which helps.

    BTW, I've never had TWS issues...that's the first thing I checked when I first got the phone and noticed the poor battery life.
  17. agentc13

    agentc13 Daleks Über Alles VIP Member

    Yeah, I like how the OV is built, but the screen, internal memory space, RAM, and processor won't cut it for me as a daily use phone.

    BTW, I've heard people mention that Juice Defender can make the WIFI on the Triumph go a bit haywire sometimes. I noticed this with Battery Defender and the Wifi sometimes refusing to turn on and having to reboot to get it to come back online. You ever notice this with JD?
  19. agentc13

    agentc13 Daleks Über Alles VIP Member

    Nope, only issues I have had were before I had JD and it was a router issue.

    JD does not function with cm7.

    Yes it does, I use it regularly.

    My experience with both OV and Triumph has been no with cm7. In the JD log, it complains about having to try something different for Gingerbread.

    The very first time after a boot, JD succeeds but when it come out of sleep second time, the log starts new and there is no record of sleep pattern history.

    This is with the free version. It may be something peculiar with my set up but check your log to see if it is really functioning.
  23. agentc13

    agentc13 Daleks Über Alles VIP Member

    It works fine on both my Triumph and my wife's OV. I had an issue with it not starting on boot, but there is a workaround for that.

    Both phones are running CM7.

    Sometimes it's a bad flash. I would suggest do a Nandroid backup of your current config, then re-wipe everything & reflash CM7 + gapps. Then before installing or restoring any apps, install JD to see if it works in that clean state, if so continue reinstalling/restoring apps (restoring titanium data may cause problems too).

    The free version of JD used to give me issues. I'm running their beta version and it runs much better and the logs show that it's working its battery saving magic. Will see how it works and then decide if I'll upgrade to JD Ultimate.
