[Q] EXTREMELY horrible battery life

I've read on many reviews (Gizmodo, Engadget, CNet, etc) that the battery on the DInc is not that great, but mine is incredibly... bad. Examples:
I browse the web (mostly mobile websites with not many images, flash etc) for ~20 mins and battery life decreases by 20%
I leave the phone ON overnight without charging and it's at 2% in the morning. When I went to sleep it was at 60%
I turn the phone OFF overnight without charging and it dies (I couldn't turn it on, had to charge for 15 mins even to turn on). When I went to sleep it was at 30%
I've also heard both that ATK is useless and that it's a gift from God for battery life. I'm running the Pro version killing every 30min and it's not helping that much (maybe 30 mins)
Is my battery defective, or are other users also experiencing this bad of battery life? My DInc is SLCD, running UberZ RC1.2 with stock battery.

Im guessing you havent had your incredible for more than five months right? Considering htc didnt start making them until the late summer. Anyways I do know that desire z ports often use up quite a bit of battery in their displays. However considering you left it on overnight and it was nearly dead I dont think it was that. Something you can try is going in the advanced menu on clockwork mod and erasing battery stats. This seems more like a defective battery though. New batteries can be bought for fairly cheap and if you do decide to get a new one you can get them for pretty cheap. Touchpro 2 batteries supposedly work with the incredible as well

Make sure you turn off GPS, WiFi, Bluetooth, etc. when not in use.

Yeah, I've had it for about a month. I will reply after erasing battery stats and trying it out. I'm not sure that I would use a Touch Pro 2 battery - seems like too much of a risk. However, I have seen Evo Batteries on Amazon that supposedly work with the Dinc. Do they?
If it helps, I use widget locker, with: extended controls, fancy widget, nexus revamped (with a lot of spawns on slow) and 3 sliders.

I have, I barely use BT or GPS so they're almost always off. I only turn GPS on when I'm charging and I'm using location based apps. 3G is off at home and Wifi is off on the road / at school and when I'm not using the phone.

What you might want to try doing is uninstalling widget locker and charging your phone all the way up. If after uninstalling widget locker the drain is still significant it may be the battery. And from what I read, the evo battery works with the incredible, it just makes the back cover fit a bit more tight.

OK, I've wiped battery stats, though it's only been a few mins so I can't tell yet. I'll reply in a couple of days. Also, can I just disable WidgetLocker instead of uninstalling it?
I also have a silicone case that hooks on the front edges, will an Evo Innocell (with back cover) mess with that?

I dont think an evo back cover would work for the incredible as they are not the same dimensions.
And btw touchpro 2 battery will work with the incredible

I just moved to an Incredible from my Droid 1 and the battery life is horrible compared... I got it as a replacement for having so many issues with my Droid but the battery life is almost unusable I'm running CM 6.1 and I wiped my battery stats, drained the battery then let it charge overnight powered off and I still get really bad life... I think a lot of it may have to do with the stock 1300mAh battery compared to the Droid having 1500mAh but I'm not sure... I'm considering the 3500mAh sedio battery but $70 bucks is a bit steep atm

Thanks for the great find, though I was thinking about maybe one of those seidio 3500's. Though since it's so cheap, I'll probably buy it

I've seen one on amazon for ~$25. Not seidio though. Reviews were meh.
I don't think its the 1300 mah vs 1500 mah. That's less than 20% (so like 10 hrs vs 12 hrs).

Didnt see the part about disabling widget locker, sorry.
Yes you probably can disable it just make sure it is definitely not running.

Don't run ATK. Android manages apps by itself. There's a whole lifehacker article on it.
Sounds like a run-away app.
Hmm, turn your screen off and let your phone sit for 5 mintues. Go into Settings > About Phone > Battery > Compare uptime vs awake. They should be AT LEAST 5 minutes apart.
If they're not, go to the market and install "Watchdog Task Manager" (<--this is NOT the same as ATK, again, lifehacker article on it) to monitor rouge apps.
Hope this helps!

My phone has been sitting and charging for ~2 hours, but up - awake = 5:12. Is it normal?
Great work, by the way.

There is no normal.
Up time is the elapsed time since you turned your phone on. (i.e. after the phone was completely off, not just screen off/sleep mode).
Awake time is suppose to only be the time your phone was actively being used (i.e. screen on).
So, Up time minus Awake time should equal the time your screen has been off, (i.e. asleep).
If Up time and Awake time are equal, and you've had the screen turned off (i.e. asleep) for part of that time, then you have some app that's staying active durning sleep mode.

I might reboot when I go to sleep tonight and do nothing on the phone, then check uptime vs awake when I wake up.

1300 Mah battery is not acceptable for a phone of this caliber. There are alternative options for battery's. I use setcpu to underclock the proc and I've seen a dramatic increase in battery life.

I've been using Setcpu as well, with 998 mhz while charging, 245 when screen off, 245-520 when hot or <20%, and 245-850 otherwise.
Agreed about the battery, HTC and VW probably want to force you to spend more on extended batteries.
Too bad, otherwise it'd be a perfect phone.

HTC usually seems to skimp on the battery. It really hurts their reviews but I suppose they can save costs and assume people can always buy an aftermarket battery. I don't agree with it but it's their business.
Anyway, that does sound like abnormally bad battery life, but I have a question - are you in a poor service area? If so, the radio might be working extra hard to acquire a signal. Even when I had my dumb phone Samsung alias (which had decent dumbphone battery life) I would experience complete battery drain if I left it in my poor coverage basement overnight.
Also, when you're browsing the web and such do you use wifi or 3g? I notice that when I continuously surf with 3g the phone starts to get warm, especially in mid-poor coverage areas. When the phone gets hot the battery gets hot, and when the battery gets hot it drains much much quicker. Of course, high power usage generates more heat so I'm inclined to believe our 3g radio consumes way more battery than our wifi radio.
Over the months I've combatted poor battery life by doing the following:
1. Purchase aftermarket batteries. I've fallen into HTC's trap. I bought an evo battery which can last me of 6-7 hours of wifi awake time and 4-5 hours of 3g awake time. I also purchased the extended 2150 battery from Verizon which I can get up to 10 hours of wifi surfing and 5-6 hours of 3g surfing. Back when I was on stock 1300 I would get 3-4 hours wifi surfing and 2-3 hours 3g surfing.
2. Install an undervolted kernel, if you're into that sorta thing. One of the main reasons I'm able to obtain the numbers above is due to my kernel which undervolts the processor. I use adrynalyne's experimental undervolted kernel and it works without a hitch. I use it in conjunction with setcpu so I can have a screen off profile which underclocks the processor to 128-384MHz while I'm not using it. The only caveat to using this kernel is you can only use the conservative CPU governor. This means lower clocked speeds will be preferred as the CPU actively scales itself, and will take longer to ramp up to the higher speeds. But we're talking about maximizing battery life so that isn't necessarily a bad thing.
3. Try to keep screen brightness down, minimize usage of other radios (Bluetooth, GPS). Sounds like you already do this though. Rogue apps have also been discussed but if awake time != uptime then that's usually not the case.
As also prevoiously mentioned, it is possible you have a defective battery and should go about getting a new one from them though I'm not sure how that process goes... someone here is bound to know though.

I definitely stand behind adrynalyne's experimental undervolted. You can find a link in the kernel thread on the android development section of this board. He makes a sense and AOSP version. I've tried some of the newer ones like Chad's but I love the longevity and stability of adrynalyne's too much to live with the switch. As aforementioned, if you decide to use setcpu, make sure to only use the conservative governer. Ondemand will cause it to freeze! Otherwise it's rock solid.

Horrible Battery life!! Any Advice?

Hello everyone, I lately have been getting horrible battery life!! I keep brightness on lowest setting, use wifi when possible, turn down haptic feedback all the way etc. do my best to save battery!
So my epic is Rooted with CWM3, and the latest frozen syndicate rom installed. Is it because my phone is rooted and the syndicate rom drains it more? is that why i have bad battery life? Does having your phone rooted drain battery life?
I ordered a Seidio 3300mah battery and got it yesterday in mail. Put in phone, then charged rest of night about it. Im using it today and am still receiving poor battery life, my friend who has epic ordered a cheap hong kong battery and is getting better battery life? I read something about conditioning your battery and draining it to 0% then charge fully to 100%? How does this work please explain?
Can someone just please help me use my new battery to its potential and help me out here?

Draining your battery for battery calibration is unecessary... there are a few threads regarding it...
Sent from my SPH-D700 using XDA App

so what should i do to improve battery life?

Rooting and custom ROMs reduce battery usage. You need to supply more details. Are you overclocking...that burns up battery usage. Have you tried Spare Parts to see what is using your battery? Has 3G been out in your area and the phone is searching for a data signal?

im not overclocking. spare parts? 4g is off- not in my area. 3g is on. what should i do. should i use my phone reguarly till it drains 0, then fully charge? i read something about wiping battery stats, shud i do tht? and i also read tht ec05 is horrible on battery life. should i go back to eb13 possibly or wht? and recommended roms?

try this thread:

I have noticed no difference in DK28, EB13 or EC05 in my battery life. Do the calibration suggested in the post above. As for ROMs it is about personal choice. I have been with Bonsai for awhile now. I hear the ACS ROMs are very stable. Syndicate Frozen is good, Midnight is good. Read the OPs, learn what they remove and improve and see if that is what you are looking for.

Running SRF 1.1, with a custom theme, brightness at lowest setting, haptic feedback all the way up, because I need to know if someone is calling, I regularly get 30+ hours per charge. The two Chinese knockoffs I have get about 26 or so hours per charge.
I have recently seen a drop in my battery, spare parts on a couple of occasions should my phone would not sleep. Sometimes a reboot would fix this, but reflashed just to be safe.
After the reflash I was still getting bad battery life but spare parts showed no issues, so I started doing the airplane toggle again and that seems to of fixed it.

whats spare parts?

Spare parts is a free program available in the market place. It shows you more detailed statistics on what is using your battery juice.

Undervolting maybe. But I got stablilty issues. ymmv anyway.
My advice is
1. Set max clock to 800mhz and min to 200mhz. The CPU is volted -75 over 1ghz and 200 is volted the same as 100mhz. I use the Conservative governer but Ondemand works well too.
2. Get a good custom rom/kernel. CM7 and Frankenstein got the best through all my testing.
3. Brightness at lowest, turn off "Notify me when Wifi networks are available", Turn off syncing for contacts, the two GPS options, etc.
4. Take out as many applications as possible(Personal preference. I think it makes a difference) But I mean stuff you don't use. I take out Bluetooth, GPS, DRM, SNS, and most stock applications. If you're using Handcent you don't need stock SMS and vice versa.
5. If you're on 2.2 and lower I recommend a program like JuiceDefender to turn off 3G when your screen is off. The latest update on the free version removed the option to filter applications using data while the screen is off.
6.Enable Airplane mode on boot up. Then turn it off and use normally. TWS
7. Definitly calibrate your battery.
8. *Insert unreasonable battery tip here*
Oh and spare parts can be installed directly from the market. It's a program that allows monitering and for changing animation speeds and such. I don't use it for anything. You should also be able to go into settings -> about phone -> battery usage and see most of what spare parts would.

is tht one thread the one guy posted to calibrate the battery? will it work?

Especially with a new 3300mAh battery! I recommend the top two as the third didn't work for me.

Juice defender on aggressive mode and setcpu on conservative mode increases my battery life when on standby quite a bit.

Don't drain your battery to zero it destroys our batteries. Don't use juice defender. If there is no reason that you need background data on like when you are sleeping turn it off but some say that's cheating but their idiots. That will dramatically improve your battery alone. Do the airplane shutdown every once in awhile some that's cosmetic but don't believe everything that is told to you. Only keep apps installed that you regularly use. Use spare parts to see if any app is causing significant drain. I'm a battery life guru.... ;-)

better battery life

I've been using CyanogenMOD 7 and love it (mostly). The one thing I don’t like about it is the short battery life. I'm kind of new to rooting phones so it took me a bit to get it rooted and get CM7 rolling. I was wondering if there are any mods out there like CM7 that have better battery life? Or if there's any thing I can add to CM7 to give it more batter life?
I've been using android since the first phone came out so I’m already knowledgeable in what to turn off to try and extend the battery life, but I have noticed a big decrees in batter since installing CM7.
Thanks for the help guys

You can under clock the processor when your phone is asleep. This creates better battery life.

your phone automatically underclocks your processor when it sleeps (for most CPU governors), you do not need to tell it to do so.
I'm not picking on you fyi, I'm just making sure we are giving people accurate information... there's only one thing worse than no information: incorrect/incomplete information.
op: which version of CM7 are you running? remember, the more minimal your setup (ie less homescreens, less widgets, manual syncing of gmail and whatever else, etc) the better your battery life will be. this is especially true of newer phones that are getting heftier cpu & gpus that, while intelligent with power consumption, are going to drain even larger capacity batteries relatively quick with moderate/heavy usage.
how long are we talking with battery life? how heavy a user are you? for reference, I get around 16 hours of battery life if I don't charge the phone at all from unplugging to battery dying with moderate to heavy usage (texting ~50 times a day, sometimes up to 100 emails depending on what's happening at work, couple hours of calls, couple hours of streaming music [pandora or audiogalaxy], couple of hours of games [peggle and plants v zombies mostly - both of which are resource hogs], etc).
I have just learned to get used to the fact that the phone is going to die if I use it a lot, so I've purchased three micro-usb cables and a car charger.. that way, unless I'm in an area where there is no charge-capable usb port nearby, I'm always able to get a little more juice if need be.

but i also mean setting the max sleep to 368mhz. by default its set at 800mhz. sometimes with apps running in the background, the processor may go to 800mhz without you knowing

check out 'powersave' and set your cpu max to 806mhz. should last you a nice long time like that. responsiveness suffers, of course.
'ondemand' and 806mhz is the best comprimise for me. still fine with HDvideo recording, streaming audio, Nav, etc
if you really want to make it last... clock down to 400mhz, turn off all the sync, set brightness and timeout to minimum, all the radios off (airplane mode), and the volume down, on vibrate.

But some govenors don't drop the sleep to the lowest profile. In fact almost all keep it above the lowest clock. Other kernels allow it and you can also use third party to set it lower. When the tweaKr script becomes universal it will be even better =)

It suffers in powersave because it stays at the lowest setting only. No reason to set to 806. Lol and that bottom comment is hella funny =), but if he does that his phone will just be...a waste of pocket space.
Your best bet is to do some research on kernels. If you are using cm7 to cm 7.0.3 id recommened pyros kernel. If you are on 7.1 or a nightly over 121 I believe id go with eugene's streamline5. It did wonders for mine Also there is a battery saving tips. Google G2 battery saving tips. Should be first link that comes up.
Cyanogenmod roms are known to be battery hungry. Nom nom nom.

I used the battery califration app if that's what you mean.
Thanks for all the help guys, i'll check out some Kernals.

Do you have link for this? I'm running 7.0.3.. but I dont think im finding the correct Kernal.

Mugen 3600mah = better battery life...

Can you elaborate on what kind of battery life you are getting now? How many hours, and for what level of usage?
How long have you been on CM? It takes a couple charge cycles of the battery after flash any ROM, for the battery meter to be accurate. Clear battery stats (as mentioned) then charge to 100%, let drain to about 20%, repeat a couple times. Don't drain until the phone dies. Some people say to do this, and its not good advice. Over discharge of Li ion batteries can cause them to no longer take a charge. There are people on here, on the Vision and other phones, that let their battery drain to empty, then the phone would no longer boot, forcing them to replace the battery.

Improving battery life?

Note to mods: I copy pasted this question from another forum to get different answers. I am the same person, please be lenient.
Hello, I would like to improve my Evo's battery, because a few texts, a minute in the browser, and just scrolling through my email brings me down to 60-ish percent battery.
I'm running the latest MIUI with Tiamat 4.0.1 or something like that. I am also running JuiceDefender Ultimate.
My screen brightness is also at a constant low, too. I should have done more research on this phone, as I'm stuck with it for another 1.5 years. It sucks. :/
My friend's iPhone lasts for so much longer, it doesn't have a larger screen, but still..
What can I do to improve my battery?

You can undervolt with vipermod

I've never used MIUI so I don't know what options you have for kernels, I imagine all AOSP Gingerbread kernels, but if I were you in would try out different kernels, even a different version of Tiamat could help. You can also try calibrating your battery.
If none of that helps, try switching roms.

I've already calibrated my battery.
Won't ViperMOD hurt my battery?

There's always the obvious. Turn off what you don't need - GPS, 3G, wifi, Bluetooth, etc. I assume that Juice Defender helps with that but I've never used it. If you can use wifi instead of 3g then you should, it saves a lot of battery. If you're in a low coverage area, that will kill your battery as well. Going through your installed apps and uninstalling the ones you don't use will help as well. Back them up with TB first if you want to save their data or easily reinstall them later. Check your sync settings, if you have social networking apps set to sync every few minutes then that's also going to chew through your battery. Using push notifications instead of regular syncing can help - try FriendCaster if you use Facebook.
I'm also running MIUI with Tiamat 4.1.0 SBC. If you're not using SBC then you may want to try it out, it can help with your battery life. I ultimately gave up on sacrificing functionality for battery life. Instead I bought 3 extra 1500 mah batteries which came with an external charger. All together it was $11 on Ebay with free shipping, took about two weeks to get here. If you decide to go that route, you can just run the battery down and put in a new one... your friend's iPhone can't do that
I still use an SBC kernel even though my battery isn't usually charged through my phone. If I forget to charge my batteries or something, I'll sometimes put the phone on the charger when it gets down to 80-90% and charge it back up. When I do that the battery lasts all day and I don't have to switch batteries.
You can also buy an extended battery, but I didn't want a fat phone. I get just as much juice - if not more - from my cheap 1500s.

I'd recommend looking up Car-O-Dope's tweaks, it's helped me be able to run the governor at 128mhz-652mhz and not sacrifice any performance. This has saved my battery life. This guide will have you download rom toolbox and system tuner, and in system tuner you can undervolt your battery as well without having to run the Vipermod scripts. In rom toolbox I changed the wifi scan interval to the max amount of time possible, and changed the wifi sleep policy to never. I leave wifi on at all times, keeping the 3g off. My battery has never been better.

This ^^^. Especially checking your accounts and sync settings

I just found a battery calibration the other day in viperboy's rom thread in e3d thread. Check that out n try it. I'm on the last part now so we will c how it goes.
Support TrevE !

So is this normal?
I put it to charge overnight, then earlier today. Would be dead by now if I hadn't today.

I don't think the Android System should be using that much battery. Mine has always been around 2 to 4 percent.

I seem to be having battery issues as of late. Been running Cyanogenmod 7.1 for sometime now...maybe 6 months lol havne't been on here in a while. I leave the 3G radio off due to it sucking battery faster than anything else. Here is what my battery currently says..
11h 11m 24s on battery
Android System--32%
cell standby--32%
Phone idle--30%
Voice Calls--5%
Display--3%
Do these look right to anyone? I would think that if someone turned off all data like myself and only used the phone for texting shouldn't it last all day? I'm lucky to get 15 hours sometimes....I have turned off everything. Bluetooth, Wifi, 3G, all syncing is disabled. I do notice when I turn the 3G radio back on the battery will almost instantly drop 10-15 percent within a couple of minutes...

[Q] Horrible EVO 4G Battery Life no matter WHAT I do!

I've about had it with my EVO 4G. I can barely use the thing before the battery is down to 30% or lower. When I first unplug it in the morning, I'll browse reddit or XDA for all of 5-10 minutes and my battery will go down to 75% easily. I've tried tons of ROMs (running Energy w/Shooter Anthrax kernel as I heard it got amazing battery life) I've tried resetting the battery stats -- i've tried unplugging and replugging in the phone multiple times when the charge light is green, I've tried just about everything I can find on here dealing with battery issues and to no avail! Listed in my battery stats the only thing that's ever high is my Display usage but even factoring that in should I really only be getting an hour or two of mild internet usage before my battery is completely depleted? I can barely make it through a 6 hour work day (checking texts on breaks, light internet, maybe a 5 minute phone call) without having to recharge it in my car.
I'm open to ANY suggestions short of buying a new battery -- sadly it's not an option at the moment.

Do you keep 4G on? That drains a battery like nothing else if left on. Same with GPS, especially in Sense Roms for some reason.

i recommend using a aosp rom if battery life is a MUST. I would suggest you use Decks aosp rom with CoD tweaks Tiamat 3.7.7 and vipermod and underclock to 500 on smartass governor........all this is what you should do if you choose decks rom

Make sure your 4G is off, but Evo is known for its horrible battery but thats ridiculous. Try a new kernal to adjust to CPU settings. If that doesn't work, you might need a new battery. Evos are know for having their battery fried easily, mine fried and I had to get a new battery. :/

You should definitely make sure your 4g, Gps, Wifi, and blue tooth is off. If that does not work I would strongly suggest you downloading Cyanogenmod 7.1. When you aren't using the phone under clock it and do medium speed when you are using it. I last around 8-9 hours doing this. Hope it helps.

Okay I installed Decks Evo GB rom and the Tiamat 3.3.7 kernel. I followed the guides but couldn't seem to do the undervolting correctly with the apps i was provided...but i'll do some testing and report back!
Can someone point me in the direction of the right app for undervolting and whatnot?

vipermod is used for undervolting http://vipermod.tiamat-dev.com/vipermod-voltage-control/

Also, it could just be that your battery is tired. Is it at all swollen, in the least bit or rock hard? It should feel firm, but give a little.
People tell me all the time, "my battery is not holding a charge", it's not designed to. But, how it releases the charhe, is another story. Obviously, it's also dependant on use. Remember, the phone is only rated at 5 hours talk time. I can't think of a time I've actually tried that, but when I have been caught on the phone for extended periods I've only gotten at most 2 hours of conversation out of a full battery.

I had an Evo, loved it,but the battery was trash,even when I bought my 3500 mah battery, the juice in it wouldn't last a whole day,sorry man,there's just no hope for that phone,without undervolting properly

my battery doesnt last too bad in my evo. granted not like the old days, but i do get about 12-15 hours on a 1700 mah battery and a powerskin charging case with a built in 1500 mah battery. This is in a poor service area.. constantly switching into and out of roaming. i keep 4g, wifi, mobile network all off and screen brightness at about 25%.. this is with moderate txt, some light game play, occasional turn on 3g to check email and browse web. im expecting better now thzt i am rooted with energy rom and anthrax kernel.
