okay i have alot of thoughts and questions on the htc evo battery life. first off i think the devs have done a great job with improving it but in reality we aren't there yet IMO. i mean coming from the hero after calibration and a 1750mAh battery i had what id call good battery life, even without the use of custom kernels or setcpu. even with calibration on the evo, the bottom line is the battery life sucks ass. i cannot even believe htc released a phone with such ****ty battery issues. ive even seen posts on here from people with extended batteries with crap battery life as well.
number 1 they should of shipped it with a higher capacity slimline battery. if it weren't for the devs here the phone would be unusable as i can remember the first time i bought the evo in july i had it for a week and got rid of it the battery was soo bad.
then we have battery mod scripts like calkins & the colin tweak that honestly never did much for my phone. then of course the much debated sbc mod that alot of people says created issues. my own take on it is it seems more of a visual effect or placebo than anything. yes it seems to hold a charge a bit longer but only when the phone is not in use. whats the sense of owning a phone such as great as the evo but be afraid to use it at all?
the reason i do not use sbc is because something to me doesn't seem right about the way it charges the battery. for example: my phone had 88% battery left before i flashed the sbc mod, then after reboot it was back to fully charged? how the hell can that be possible?
so im sorry for venting but sometimes i think i may look into a smaller android phone such as the optimus s or another hero. does the evo shift have these issues as well?
so now i ask for advice from the users that "claim" to get well over 24hrs battery life on stock batteries. im running myn's rls4 rom with the netarchy 4.2.2 /less havs/ no sbc kernel. if i choose to use setcpu and do not want to overclock what settings should work best? or did i hear that havs & setcpu do not play well together?
thanks for listening!
My biggest issue is that it's very inconsistent. I'm on MikFroyo 4.3. When I flashed this ROM I upgraded to all the newest radio, PRL, PRI, etc. It used the stock HTC #15 kernel and I was getting OUTSTANDING battery for the first 5-7 days. Then, literally overnight, my phone started losing 10% of its battery per hour while NOT IN USE. And, no, it wasn't the Up vs. Awake issue, I hadn't installed any new apps, none of that. So I "downgraded" PRI to 1.77 and STILL, absolutely horrible battery life. I've tried different kernels but nothing works. I can take my phone off the charger at 5am and be down to 15% battery by noon with LIGHT use. Signal strength isn't an issue either. It's just frustrating. I understand that these phones have large displays and constantly multi-task but you would think HTC would realize that these phones are going to be used by "power users" and plan ahead for it. But I suppose if our battery wasn't an issue we would just find something else to ***** about all day, lol.
Try miui, that rom gives me the best battery life I have ever seen.

+1. I get better battery life with my EVO running MIUI than I did on my Motorola Renegade clamshell phone, and probably twice the life I got with my Hero. I replace my battery with a charged one every morning and I generally still have 50-60% life left when I do that. I have gone 2 full days on a charge. I did not get this kind of battery life out of any sense ROM I have tried.
You say, MIUI, I say CM6 or 7. All depends on what you like, really in regards to ROM.
I can say that I do get better battery life on CM vs something like Myn's. My phone does stay on for more than 24hrs with somewhat light usage. That means the display is on for about 2-2:30hrs in that time while I browse the web or look at videos, but the rest of that time, it has all of its radios on and is constantly pulling down updates for Twitter, FB, NYT, and Yahoo Mail.
I haven't had any sudden drops in battery life, but if I did, I'd probably buy a new OEM or near-OEM quality battery to replace it.
My BB Tour used to do far less and yes, it lasted longer, like days without a charge, but it didn't have all this stuff going on. So yeah, comparing this large bar phone with its huge display, on-going processes is sorta unfair.
That said, I do wish it lasted 2 or 3 days with light usage.

Coming from Myns rls 5 to cm7 both with stock kernels I could honestly say I see better battery life wit no OC on the CM7 rom. From my experience using warm 2.2 roms, I could get nearly 40 hours on the phone but in order for that to happen I have to barely use it. Which basically means its pointless. I mean if that's the case I might as well leave the phone turned off. Not to mention how much of your time that gets consumed searching for the perfect kernel to fit to your liking and phone.
I really do think the battery sucks on the evo but there are ways and roms to make it manageable. Sooner or later the new duel core & Tegra processors will be here soon, so bad battery life should be a thing of the past. Only because the CPU wont work so hard while sharing the strain we put on are phones. Lets just all sit tight and let technology take its coarse.

+1 for MIUI. This is the best battery life I've ever seen. To the point where I stopped carrying my charger around. I still keep and extra battery just in case but I haven't had to use it in weeks. I get through the day easily on a full charge and I have no problem charging mine at night...I've been doing that since back in the day with flip phones. I thought everyone charged overnight while sleeping or is that not the norm?
Its also a norm for me if it needed it. Another reason I think MIUI and CM Roms are good on battery life is because ultimately they don't have 4g. I've been on the same charge all day and I still got some juice left to flash the new nightly for cm7. U gotta love it.
r0cky.Da.3v0.SU.-
Doesn't CM have 4G now? Even when I was on Sense roms I rarely ever used the 4G though. Same here though, I took my phone off the charger around 3pm, got home from work around 4am and still had plenty of juice left to back up, flash the new MIUI rom, and set it up. Seems like battery is getting better with every new release. No complaints here.
I don't get 24 hours battery, but I don't lose any battery while idle on a sense rom either. I'm on mikfroyo, with net's 4.3.1 cfs havs nosbc kernel. I'm using setcpu, and my screen off profile is 245 min and max smartass. With the screen off I barely lose any battery at all. I charge my phone periodically throughout the day, but I've gone 10+ hours off charger (with moderate usage, but no gaming or anything like that) and still had a good 40% battery left.

Honestly anything over eight hours is descent especially if u still have juice left over. Even with that said and speaking for all the cm users, I can honestly say that netarchy kernels are definitely not needed using this rom. Even though its a great kernel, That would be kinda suicidal towards my battery life.

Hey there,
I want to know what is the BEST setup to maximize battery life. What ROM? What Kernel? What UnderVolt ( if any )? What Radio?
My room mate has an iPhone that he modded and it now lasts two days without being charged and that's with moderate usage. I'd like to out do him with my Android. Any help?
-Reiz
So far personally I've had the best experience with the following :
ROM : CM7 ( 7.0.0 )
Kernel : Tiamat 2.6.32.27
Radio : 11.19
I can't seem to get undervolting to work since I don't have the folder that Viper describes even though I am using an AOSP rom ( as far as I know ) . o.o It's odd really... Anyways, that usually gets me about 20 hours of usage or so .
Twenty hours isn't bad, as the Incredible isn't known for it's battery life. You won't get what your roommate's getting with his phone, maybe get a bigger battery...? I don't think you're going to really out do yourself with the experience you've posted, I'd be happy with that.
I am running SkyRaider 4.0, Chad's 12232010 kernel, OC'd to 1.0368 (small OC, I know) with the leaked 04.08 radio, and I can get about 20 - 24 hours before charging, low to moderate usage (no games, emails for work/personal, maybe 1 call of 5 minutes, lots of web browsing).
Cm7 stock kernal. On metro pcs with a seidio 3500 mah extended battery. Unplug at 7am 12 hours later only sitting on 74% lmao. And in that time bout 100 text. And 200 work emails.. and 30 mins of surfing on lunch. This setup has been the best for me on bat life.. used to run sense and my bat life would just suck..

Two things that will kill your battery faster than anything:
-Anything that syncs
-your screen
So, turn your brightness and screen timeout down and turn off anything you don't need syncing all the time, or at least turn the sync frequency down.
Also, keep your wifi, vibration, tactile feedback, and gps off unless you really need it.
Kernels, roms, undervolting...no where near as effective.
Think about your phone as a smaller version of a laptop (which it pretty much is), what's going to save you the most energy: throttling your cpu speed, or turning the screen brightness down?
Much love brother
Which kernel do you guys prefer? Gladdos is awesome because I love its app with sound options . App seems to also work with Franco kernel though, but as far as reliability and performance goes, which do you guys like more?

Personally I'm a big fan of the CM9 kernel. I use CMPlus by Cheekybutt simply because headphones sound like crap without Ezekeel's high performance audio mod.
I use Glados. Its outstanding. I find I can oc higher much more reliably. I use 1.6 for everyday usage which is not even seen as an option on many other kernels. on a lot of other kernels, Franco included I can't run higher than 1.35 CPU and 384GPU. I run 1.6 and 512 with glados. And the app kicks ass with tons of adjustable features!

From what I've heard (not tried), the gain from OC'ing is minimal and battery consumption increase is quite big.

why do you even need to overclock? To me battery life is most essential factor and I have yet to come across a kernel that can give me satisfactory results, stock included. The screen on this thing is beautiful but eats battery like no other. I can't wait for Verizon to have a larger Note like device so we can have a larger battery.
The battery life on this phone is amazing for a Verizon LTE phone. Before I activated the phone I played with it around the house for about a week (had to take care of some things before I quit using the iPhone). I went 25 hours with 3 hours of display time. Mind you this was all on WiFi and since it wasn't activated there was no talk time. LTE is the battery destroyer not so much the screen. I have never ran this phone stock, so I have no benchmark to compare it too, but the charging times on the Franco kernel are insane. Went up 65% in 1 hour over a car charger.
I'll have to check out the Gladdos kernel.
what car charger do you have and what apps were you running? I have a 1.2amp usb charger from monoprice and with maps and pandora on it charges for a bit before it gets too hot and switches to "not charging" to not overheat. Then it stays at about the same battery level, give or take a few %
Something similar to this....http://www.newegg.com/Product/Product.aspx?Item=9SIA07Y02A5396. Since it's dual port I'm sure it has a bigger fuse.

I suggest reading through the Franco.Kernel thread.. everything above 384 is minimal at best.

which brings me back to the another comment I made in another thread, LTE speeds for a phone is unnecessary. Lose battery life and pay up the wazooo if you don't have unlimited data (soon all of us)? Just a way for the big red to justify charging more. #switchingoffLTE

Then why offer a 512oc if its nothing? Reality is, the phone is noticeably smoother with it. And virtually no hit on battery life. I'm still getting high 3 hours screen on time and 20+ hours battery life. I'll take the much smoother experience for minimal battery life hit.

Much smoother? Exaggerate much??
And as for battery life, I get 5hrs screen on with 384.
Games run smoothly, UI is smooth, what more do you need.
If you can run 512 then why not but it does not make that much of a difference.
I have used both and I find no difference.

Well, for me on my phone, its a major difference between 384 and 512. And I've seen several people comment that it is a difference on their phone too. Web pages scroll is jerky on 384 for me, and with 512 its perfectly smooth. I've never ever gotten 5 hours screen on time with any setting I've ever chosen on my phone so thats not even in the question. Max ever was 4:30 screen on, that was with screen brightness lowest possible, entire time with wifi, which is not even in the question for me on a normal day. Normal for me is high 3's.
Anyways, we all know none of these phones are the same. They react differently to different settings. All I know, is on my phone, 512 is by far smoother than 384. And at a 40% OC of the CPU (1680-1700mhz) the phone is also noticeably faster. And actually, on my old Galaxy S, 1400 was the magic number i needed for things to actually FEEL and LOOK faster, which was 40% more. Anything less than that, I couldn't notice a boost. Thats just my thought on my phone.
Its very easy to see the difference in scrolling smoothness between 512gpu and 384gpu.
All you have to do is go to theverge.com mobile site and just scroll up and down using the stock browser.
The difference is very noticeable.
Glados 1.34 seems to resolve data drop issue, so I've stuck with it for now.

On GB: Juggernaut/Synergy
On ICS so far: Telus stock v4.0.3/stock kernel
Darkside Telus 4.0.3 build has fantastic battery life for me. I get about 2% battery drain per hour (when the phone is sitting idle) and on a typical day I will still have more than 50 - 60% battery left when I go to bed. That's after the phone has been on for 15 or 16hrs with moderate use.
If I use the phone more heavily I can get over 3 hours of screen on time.
If we're talking ICS rom's, I'd say 'CM9 20120620 Unofficial' gave me great battery life. I used it for almost a week. I had BLN disabled and was very impressed with the battery life. I could make it an entire day with mod/heavy use. I've run several ICS rom's, and by far it beats them all hands down. It might not be on par with our GB rom's yet....but it's getting close. They've now removed BLN support from the kernel because of the battery drain. But I found just disabling it was enough for me.
I'm getting ready to flash nightly 6/27 with bln disabled. I'll see what kind of improvement I get, if any, with it being disabled.

i put on darksideevolution v7 yesterday and after 10 hours i had 65% left. i did about 40 minutes on the phone, texting all day, wifi/data turned off when it wasnt being used (easy to turn on/off with the toggles)
Honestly I haven't had good battery life since I got this phone 2 months ago. I've been tinkering alot, mainly with Darkside and now AOKP with Eugene's kernel on lionheart. My wife's stock t989 gets great battery life, but I can't live in stock. It seems like I can leave my phone unused sometimes, maybe overnight, and the battery life is great (9% used in 10 hours) but as soon as I pick it up, it drops 20%. Must be that big screen. Anyway, I'm trying to get this worked out. I'm getting my preferred rom figured out and then hoping to let the battery settle into it. Always an experiment...
Leave ICS and get back on GB.
Ive had this phone since the day it came out. Switched to ICS once the developers started dropping ICS leaks, etc.
For the past 2 weeks for some reason, Ive had nothing but HORRIBLE and i mean HORRIBLE battery life. Phone would not last me more than 4-5 hours of heavy use. I'd have to carry around my portable battery pack to charge the phone on the go. I did everything to my knowledge to try and conserve battery life. CPU tweaks, battery monitoring, tried different ROMs, Kernels, Modems, etc, etc. Nothing would significantly improve battery life. I even went ahead and ordered a new battery last week to remedy this problem (which has not yet been delivered/used)
2 Days ago I flashed back to Blazer 4.0 ROM (GB).
I unplugged my phone yesterday morning at exactly 7:30am. Did not step back into my house until 530 which at that point I was at 35% and had been using my phone all day as I normally would. Web browsing, tons of texts, Used Navigation for about 2 hours, etc. I did not plug my phone to the charger until 10pm. Phone was on 19% then. Mind you, this is on the first day of the Phone being on a new ROM/GB so the battery has not yet settled/calibrated as Its only been charged Once since flashing over.
I refuse to switch back to ICS for the sole reason that battery levels have obviously improved with something as simple as switching back to GB.
Just a heads up for anyone with ICS on their E4GT having issues with battery life.
If only I got a dollar for all the times a thread like this is made.. I'd be rich. Blah blah ICS sucks yes we know... So far my phone must be a super phone because it's handling ICS well.

I agree with you, Ray. I'd also be rich for every time I've read of E4GT owners who's phones are running ICS with no problems. But then theres the bunch who also complain that they have problems. I never stated ICS sucks. At this point these phones are old by today's standards. Be glad you're one of the ones who's running ICS with no issues. I for one will stay on GB until I switch to a new carrier/new hardware sometime soon.
Just thought I'd give some feedback of my experience with battery issues on ICS in comparison to then switching back to GB.
I don't know if you've tried Blazers ICS ROM, but that thing has some AMAZING battery life. I've been running it for a few weeks now, everyday I get at least 12 hours of moderate to heavy use, without my own tweaks, and by the time I connect to charger I'm at 35%
Arguments apart
i have a few friends all on this or that ICS and none of them is happy with the backup
whatever its a fact ICS goodness never really reached E4GT, lets hope FI03 onwards some sense prevails at those losers at sammy and they push something which we can smile about.
FYI i am also on ICS Rom , still in testing phase after getting my new white beast 10 days back , already tried like 3 , each for three days
running galaxy 1.8 since yday and hoping it shapes well otherwise i ll also move back to GB
I've tried multiple ICS rooms and I've always gotten great battery life (14+ hours with 3+ hours screen on time).
The only times I've ever had battery life issues were when a certain app was the culprit and was keeping my phone from deep sleep or causing frequent wakes, which is almost always the case with poor battery life issues.
Check out an app called GSAM Battery.. it will tell you what is using up your battery in easy to read graphs and percentages. Also, check out CPU Spy to see if your phone is actually going to deep sleep mode when you turn your screen off--again, it shows you in an easy to read chart with times in each state.

I got over 30 hours last weekend with light use, but the next day, my battery would drain 5 to 10 percent per hour with no use. I have all the utilities to track what's happening, but cannot find a definitive cause. Poor reception seems to be a factor, but not the whole story.

Only the stock ICS rom is garbage with poor battery life and stupid stuff like grey text on black back ground. I have ran several custom ROMs and they all provided better battery life. As I have said before, I got 99 problems but battery life ain't one of them. You must be doing it wrong.

Still waiting for the new battery to arrive. I would love to try it but I'm in the midst of a heavy usage of Verizon PRL on my phone. Sprint doesn't like heavy roaming users from what I've been reading. Sprint 3G in my neighborhood here in NYC sucks Donkey nuts. I can cross the street and get 3 bars more than I have sitting on my front porch. But thats a whole other topic of discussion.
Im not sure why my phone couldnt play well with ICS but it really was horrible. I consider myself a heavy user and ICS couldnt keep up with battery demands. I tried undervolting, etc. Oh well. Been eyeing the SGS3 or the upcoming SGNote 2. Time will tell.
So far 3 days on Blazer 4.0. All my apps are restored via TB and no issues with battery like I had on ICS. Don't really know what else to say. :good:
My phone would last a week on cupcake

I'm getting 24+ hours on standby time. I have gotten about 18 hours with about 3 hours of screen time. Facebook and GBA emus. I wasn't able to do this since GB. I have done this by doing one simple thing. Turning off data. I kid you not. Utilize that data toggle. I know at first you're thinking no I need data. But you don't. Unless you're some business person, then this excludes you. Wanna check Facebook?
Also, wii benefit from something else. 4G WiMax. You can turn that on even though your data is off. You still get decent battery life since 4GWiMx knows how to sleep. Also, if you're driving around, it'll pick up 4G eventually (unless you don't have it) and it'll download what it needs to download. So by time it turns loses signal, you'll have your emails. I tried this and I still got good battery life.
Using Battery Monitor Widget, I was able to see that my phone wasn't "sleeping". That's what the main problem was. That's why I wasn't able to find any rogue apps using Better Battery Stats. But I did see my phone stayed awake. Like once my phone died in 5 hours. 10 minutes screen time. 6 minutes of deep sleep. Really? That means my phone was awake for over 4 hours!? Doing what!? No app was at fault.
Extra stuff. No need to read if you felt you read enough
An app you all should check out...

Battery Monitor Widget (It's not just a widget. LoL!!)
It tells you how many #mA your phone is using. So if it shows 500mA. That means your phone is using 500mA per hour. Your phone has an 1800mA battery. So that means if your phone used a constant 500mA, it would die in 3.5 hours. This is a good way to see just how much power your apps are using, or if after 10 minutes your phone is actually sleeping. My phone actually started using 2mA. I haven't seen that since GB. I thought my phone would never sleep like that again. I cried.
P.S. If you get the app, in settings -> Calibration, change the battery amount from 1500mA to 1800mA. Apparently the app thinks our battery is 1500mA. Or maybe my battery REALLY IS 1500mA. I mean, it got my Nexus 7 battery correct. I didn't have to change it. I've always wondered why BMW said I had a 1500mA battery instead of 1800mA. I may have to look into. Wii all should probably look into that.
Also, those on Blazer ICS ROM. Using BMW, I was able to see something quite interesting. My phone would use a lot of energy. Like 1000mA just to send some text messages, or scroll through my app drawer. BUT, after I stopped using my phone for about 10 minutes, I'd turn it back on and BMW would show my phone gaining #mA, or charging. This means something is causing the phone to "drain", or show drainage, when there really isn't. The fact that the phone charges back means it never really used that much energy in the 1st place. But that only happens on this ROM. Since I figured out the data thing, I'm going to try CM9 again.
