What's the best way to save battery life while using the seidio 3500mah battery

I am trying a way to save battery life on my phone and I charge it for about 6 to 8 hours and erased a lot of applications is don't use but it drains out every minute and I have to leave it in airplane mode to really save battery life can someone please help me with this.

It's a thread in the development section called superior kernel I think just look at the first page it's a special kernel that works with that battery.

Turn off the radios you're not using: Bluetooth, 4G, wifi. Turn off always on data inside the wireless network settings. Keep your screen brightness down. Install "Juice defender" and set it up. If you're rooted then use a kernel built for battery life and use the Collin_ph battery tweak.

Swyped From Eva Running Myn's RLS4!

I have a seidio as well. Im using myn's warm with calk's 131 kernel witch is supposed to add trickle charging. I am getting kick ass life. Close to 2 days. I found out that with these bigger batts you have to leave them on charge for about three hours after the light goes green. Something bout the phone going green when the batt reaches 1500. Charging over night is what I do. Oh ya, I also have my cpu clocked up to 1152000 and I still get this great life. Let me know if this works for you. That kernel is located at this thread, and it should work for most roms- http://forum.xda-developers.com/showthread.php?t=876590
Look for the one that fits your rom. There are different ones for sense vs. aosp. If you're not sure post a reply and ask for help. Include the rom you're using.

thoughts on evo battery life?

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.

Keep in mind these phones have 8mp cameras, 1ghz processor and tons of extra memory. Basically the equivalent of the lap top computers of 2 years ago.

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.

Yeah, CM6 has wimax but CM7 doesn't. On the account of the Rom isn't stable yet.

[Q] What is the best kernals for Cyanogen mod 7 rc4

Hi I've been looking around to find good kernals while running cyanogen mod 7 rc4. Some of the kernals I install like netatchy gives the screen a weird flickering. Can someone suggest a good kernal that's overclockable and stable. Thanks

Netarcys kernel really isn't for cm7 that's probably why its flickering. You should try savage zens latest sbc or non sbc kernel or tiamats sbc kernel both are pretty good. I'm running the tiamat sbc 3.3.4(great battery life) and I'm pretty happy with it.
Tiamat link. Be sure to get the evo version because he does kernels for the incredible also.

In a nutshell, sbc is a method of charging that allows you to "fully"(trickle) charge your battery. Normal kernels really only let you charge to about 90% for safety measures; while sbc lets you fully charge letting your battery completely fill. There's a few threads that talk about it if you search around to get more "details". I've been using them for months without any problems whatsoever. Good luck

Honestly I get great performance out of the stock kernel.

That happens to me sometimes but not all the time. I believe that's still a problem with cm7 in general though. For best results I recommended going to settings/ cyanogenmod settings/ performance/CPU settings then use the "smart ass" governor. It has provided me with the best overall battery/performance. I also have my min freq at 245 and max freq at 1152.

Those are also my settings, I've discovered my evo can't go beyond 1.15ghz without locking up. I've been trying to get to 1.2 but no go

I don't really put so much stock in scores anymore they don't mean anything to be honest. Dirk used to be a score whore but I just removed the apps so I wouldn't worry about it anymore. I came to terms that my scores won't go much higher then what they already were. Just ran 40 mflops and 1220 bench.

Yeah I just like the braging rights, hopefully they can figure how to overclock the gpu soon tho

Bragging rights how's this for bragging rights; my 12 year old cousin has a tmobile g2(newer processor) which is stock clocked at only 800mhz. His phone scores a 60 on linpack and over 1500 on benchmark and its not even rooted lol. This is why I don't care about scores anymore

I just died a little inside :/ lol I wanna upgrade to the evo 3d soon tho and that's a dual core

I just wanna correct this misconception because it led me astray and it took a good amount of research to realize this was wrong.
All kernels will charge the phone to 100%. That's not an issue. What happens is, once they are charged to 100%, they start draining battery again, and coupled with the fact that li-ions inherently lose charge over time, and the fact that most people haven't conditioned their battery's memory by properly charging it, by the time you pull your phone off the charger it's already lost that 10% (give or take).
Trickle charging hopes to fix this by "trickling" a small charge into the battery constantly once it hits 100%, to compensate for discharge, so that it stays at 100%. The problem with this is, it pushes a current through the battery constantly, and that tends to shorten the life of lithium-ion batteries over time. You may get better immediate battery life off the charger, but you'll kill your battery quicker. Come months from now, your battery life isn't going to be what it should, whether you notice it or not.
If you want to minimize the discharge, you can take a couple safer steps:
- Condition your battery. Charge it to a true 100%. This will mean turning the phone off and on a few times while it's on the charger to make sure it's actually at 100%. Then completely discharge it until the phone cannot turn back on. Do this a couple times in a row, and repeat every month or so. This conditions your li-ion battery's internal charging memory so it knows its true charge potential.
- Charge your phone while it's off. It won't drain nearly as much battery this way, so when you're ready to take it off the charger it'll be much fresher.
- Avoid prolonged charging and continuous charging, because it can confuse the li-ion's internal charging memory. Rather than re-charging it when it hits 60%, let it drain as low as possible before you bother recharging it. Bursts of short charges don't harm the battery, but they make it "forget" how much it can be charged.
In short, SBC kernels are bad for your battery.
---
Also, Savaged-Zen 1.0.1 BFS no-SBC has been the best kernel I've found for the Evo 4G. Granted I haven't had this thing that long and there may be another gem lying around somewhere, but given the popularity of SZ, I doubt it. It's a very good, smooth kernel. It's giving me the best performance of what I've tried (most of the popular ones).
As for CFS vs BFS, flip a coin. Some will swear CFS is smoother, others will swear BFS is supposed to be smoother. BFS gives me more responsiveness personally, but I think it mostly depends on your workload. I keep scarcely-used tasks killed and I don't use widgets, so the lack of many processes may be what makes BFS better for me. Try both and see which feels smoother in daily use.

That's a great plan man. I visited the savage zen kernel thread earlier and some are complaing about their newest build causing charging issues or something along with 100% wake time idk. If you give it a shot use their 1.0.0 instead of the 1.0.1. Just give the kernels about a week and see how well they hold up. Its mainly about personal preference(sbc or non sbc) I'm actually testing the tiamat sbc but I was previously on savage zen. I like to give all kernels a chance(1 or 2 weeks) to see how well my phone performs with them.

Ok well ill just wait till Friday to install a new one then and see how the Zen works out

[Q] Poor battery life -- halp!

I recently got into rooting and flashing at the end of last year. This site has been a great resource for how to's and learning about the ins and outs of phone hacking.
Anyways, here's the background info: rooted using Unrevoked Forever, s-off, stayed with stock ROM and kernel only using SetCPU profiles. When I was on stock software, I had unbelievable battery life. I'm a light user (~10% awake time) and rarely beat on the battery -- light calling, email, texting, Facebook, random messing around etc. Anyways, when 3.70.651.1 came out, I knew that was my chance to flash my first ROM.
I flashed SprintLovers and got decent battery life, but nothing compared to when I was running the stock ROM. I then tried almost every variation of Netarchy's non-SBC's CFS 4.3.4 kernels -- more HAVS, less and no HAVS. No dice. I've tried with and without setCPU altogether, along with and without setCPU profiles but using the smartass and conservative governor. I always set the processor to 245-998 and never overclock.
I liked myn's Warm TwoPointTwo, so I recently tried that last week. Again, I'm getting okay battery life (~1.5 days) but with the usage I'm at I'm pretty sure I should be able to get 2 days easy. So I tried flashing Netarchy's 4.3.4 non-SBC CFS kernels with the same results. I've also tried with and without setCPU, along with and without setCPU profiles. Finally, I gave up and I'm currently using Netarchy's 4.2.1 cfs havs more smartass and using setCPU.
It's definitely not related to PRI 1.90 as I'm not getting the 100% partial wake time in Spare Parts, and I know the consensus is divided as to whether or not setCPU interferes with HAVS. I know all phones are different and ROMs and kernels interact differently on an individual basis, but I would really like to stick with myn's ROM and a good kernel to max my battery life. rather than go back to the stock ROM. Any suggestions on extending my battery life before I shamefully reflash back to stock software? I always do a full data/cache/dalvik before flashing a ROM, and wipe cache/dalvik before kernels.
myn's warm TwoPointTwo RLS5
netarchy-toastmod-4.2.1-cfs-bfq-havs-more-smartass
PRI and NV 1.90
setCPU 245-998 conservative
setCPU profiles:
temp >50*C = 245-499 powersave priority 100
screen off = 245-384 conservative priority 98
charging AC = 245-998 smartass priority 96
charging USB = 245-998 smartass priority 94

Try recalibrating the battery. Charge to 100% and leave it on the charger a little longer. Then turn the phone off and boot into recovery. In recovery wipe battery stats - in Amon Ra it's under the wipe menu. Boot back up & use the phone normally until the battery drains completely, without charging the phone at all. Some people say until the phone turns off on its own, but I'd try to avoid that. Just get it as low as you can. Then once it's dead, charge it fully without breaking the charge until it's completely full. You should see an increase in life after that. There's also an app in the market that clears your battery stats. I believe it's called "Battery Calibration", but I could be wrong about the name.
Since you don't use your phone much you'd be a good candidate for undervolting. If you don't want to undervolt while the phone is in use, just use a screen off profile only. Turning radios off while you don't have a signal or you aren't using them will make a huge difference as well. Let us know how it goes

I've heard people recommending a battery calibration after flashing a new ROM. My battery has seemed to be jumping down a few %ages and then stabilizing for long periods of time at a single level. Perhaps this is what I'm missing. I'll give it a try tonight when I recharge and see if that helps. I may try undervolting, but seeing as I got great usage on the stock ROM with the same CPU range I'd like to stick with 248-998. I always have a screen off profile though (as noted in my first post). I've also heard about people shutting off radios and such but I don't think I'd want to take it to that extreme -- maybe if I get desperate enough to eek out that much juice I'll give it a shot.
Bonus: to alleviate my problems at home since I have terrible reception and I know that eats the battery, Sprint is shipping me an Airave free of charge! In the process of trying to contact Sprint's CS (*2 on the dialer), the phone was force closing *1 and *3 work fine, as does normally dialing so I guess the problem is only limited to *2 (I even rebooted and am too lazy to reflash just because I can't speed dial a number I rarely call). Hopefully with your suggestion, I can get back to insane battery life

Don't know if this will help you out at all, but here's my setup...
myn's Warm TwoPointTwo (RLS5)
Net's toastmod-4.3.4-cfs-havs-more-sbc
Launcher Pro Plus
SetCPU:
Screen Off: 128 max, 128 min conservative
Battery<101%: 499 max, 128 min conservative
MinFreeManager:
Set to Aggressive
Twitter, Flikr, and assorted useless (to me anyway) apps frozen with Titanium Backup
Unplugged at 0700 and as of 2205, my Seidio extended 3500 battery is STILL at 74%
Average usage day, with tons of emails, and SMS/MMS messages. About 2 hours of web surfing and 3 hours of Pandora, but not a lot of phone calls today though. About 7 hours spent on WiFi, the rest on 3G (No reliable/stable 4G near me yet).
Background data off
Auto-sync off
Enable always-on mobile data off
I have noticed this is the best battery kernel I have tried out of all of Netarchy's (ymmv). I've had this kernel for 2 weeks, and getting 2 days out of it with HEAVY usage is no problem. I only lost 4% of the battery from 2300 last night to 0700 this morning with the phone sitting on my nightstand.
It seemed to not last as long at first until I wiped battery data and started from scratch. Always a good idea to wipe battery data when swapping ROM's and kernels I notice. Also read (here, of course) that new kernels have a "break in" time of a few charging cycles until they settle in.
Overall:
Completely satisfied with this setup. ROM is lightning fast, and battery is a non-issue with this kernel. Only ever so slightly laggy when opening Handcent or galleries (when I add pics and albums have to rebuild the thumbnails), but what the hell, it's only running 499mHz! Even fired up Avatar from my SD to check for stuttering, clipping, or audio lag. There were none!

OH!!!
Almost forgot!
I stumbled across this "trick" a while ago. Not sure if it ACTUALLY works, but at least to me it does.
It's called "Super Charging" your battery.
Charge with phone on until green light signifying charging is complete comes on
Disconnect charger
Shut off phone
Reconnect charger
Amber charging light will come
When amber changes to green, disconnect charger
When Green shuts off, reconnect charger.
Repeat process
I was bored this weekend, and did it for 4 hours continuously. Yeah, that is truly bored!
I had charged it so much that upon disconnecting the charger, waiting for the green light to go off, then reconnecting the charger, there was NO amber light. Straight to green. Tried it a few more times, with the same result.
Did it actually "supercharge" the battery? Who knows?
Did it take 3 1/2 days of use to break the 25% remaining mark? Yes it did!
So if you are bored, I mean CRAZY bored, what the hell! Give it a shot...

OH!!!
Almost forgot!
I stumbled across this "trick" a while ago. Not sure if it ACTUALLY works, but at least to me it does.
It's called "Super Charging" your battery.
Charge with phone on until green light signifying charging is complete comes on
Disconnect charger
Shut off phone
Reconnect charger
Amber charging light will come
When amber changes to green, disconnect charger
When Green shuts off, reconnect charger.
Repeat process
I was bored this weekend, and did it for 4 hours continuously. Yeah, that is truly bored!

I always wondered if you did that enough, would it eventually get to the point that the light went right to green

Thanks, but not willing to step into the realm of SBC kernels. However, I will try to go through a few charging cycles to see if my current NA kernel just needs to get broken in. I've also tried the charging method you stated above and while I did get good results, I'm unsure as to whether or not this is overcharging the phone so I decided not to do it again.
Anyways, I wiped batt stats last night after getting the full charge, so still on the drain and need to recharge to 100%; will report back after I go through a few cycles of charging.

Why not an SBC?? Because it fully charges your battery closer to 100% than a non-SBC?/
And don't buy into the hype of exploding batteries. That was handful of cases, that a) were all reported in the earliest days of SBC development, none since and were never fully attributed to the SBC kernel.
Also, you people that say drain til it dies, you DO realize that HTC STRONGLY recommends NOT doing that. According to HTC, you shouldn't recharge until you get below 50%, and no, I'm not gonna go look for the links, use the search feature.
I have a good method in my signature. Give it a try.

Can't argue with a battery that stays at 100% for 3+ hours then slowly drains versus unplugging it at 100%, blinking twice, and seeing 90% remaining...

Well, I'm no developer but if Netarchy says to beware in his latest kernel thread, even if for liability reasons, then that's good enough for me to stick with non-SBC until an SBC kernel is proven to be 100% safe. I think that's a perfectly valid justification to not use SBC for now.
I keep forgetting that we're not supposed to completely drain the battery. I guess I'll recharge when I hit 5 or 10%.
I'll take a look at your thread when I get a chance.

All threads (for the most part) say that, even ROM threads about not being liable if anything happens to your phone. Not even flashing a ROM is 100% safe but you do it anyway.
I've been using SBC since it was being tested the first time and I've never had one issue. No batteries have exploded, no chargers bursting into flames, and no phones have self-destructed.
If you want really good battery life, good performance, and want to try something other than Sense, CM7 and MIUI are really good ROMs. I would recommend Tiamat kernel (use 3.3.8 for now, 4.0.0 has some issues) and make sure to wipe batt stats and do a battery calibration. For good measure, you can try my BSM mod in my sig for even better battery life.

kings kernels are awesome!! im using one and is giving me 30 hrs!

He doesn't support the EVO anymore, to my knowledge.

Yes, all threads use the release of liability clause, but NA specifically states in his most recent thread that SBC could potentially cause problems.
Gosh, so much peer pressure! I'm not saying I won't ever go to SBC, just when I feel like it's a bit more stable and all the kinks are worked out. Kind of like you probably shouldn't buy the first model year of a car since the chances of running into glitches is much higher than if you waited a bit for the bumps to get smoothed out. If I'm being paranoid -- well, it's all in the interest of my $200+ phone. Regardless, I appreciate all the replies.
I've heard about MIUI here and there. I guess I've stuck with Sense since that's all I've ever known, but maybe I'll start branching out to AOSP and MIUI. Does CM7 have full functionality now on the EVO?
I'm on my first recharge since wiping stats and it's the fastest recharge I've ever seen. Maybe I do need to just break the kernel in?

Root/rom/battery question

Droid incredible. Rooted, virtually every rom through rom manager causes my phone to battery to drain very fast.
After a charge itll drop to 90% in about twenty minutes. Iv heard thats a droid thing.
From that point, it steadies but still is losing juice FAST. Phone has been awake for 8hrs today with light usage and is currently at 70%. Gps off, wifi off, etc. No vibrating feedback, auto brightness.....all settings geared for battery conservation.
Im using Incrom 1.6 with a stock kernal. Any ideas or thoughts are appreciated as i dont stop hearing that everyone in the world is rooted and enjoying their batterys new ability. Ohhh, btw extended battery, red htc one in case that matters.

Try flashing some new kernels..try a couple out. If that doesn't work did you over charge your phone? Or use a car charger?
sent from my Dinc

Its not the battery cause when i revert to stock the battery is normal for what im used to. The change is noticable wen i use any of the custom roms.
Right now wrkng on flash radio, hit a bump waiting for email back.
Ne other suggestions from u or nebody wud be apreciatd

I use the app batterycalibration after flashing new roms it works well for me

Everybody's definition of "light usage" is different. Losing 20% in 8 hours doesn't seem that bad to me unless you litterally never turned your screen on. That said, here are some things you can try:
1. I've found that the auto brightness sucks and I'm better off just manually setting it to 25% or so. That's fine for indoor use and you can't see the screen in bright sunlight anyway regardless of the setting so why bother burning battery trying?
2. Try flashing a kernel that allows you to underclock and undervolt. Perhaps one of Ziggy's nonHAVs kernels (I have found that HAVS kernels to be unstable, but YMMV). Either use the smartass governor or setCPU to cap screen off at 384 MHz.
3. Carry a charger with you

I'd see what is using your battery in settings.
Also, you could try chad's sense (12/28 I think) incredikernel, which sets the max clock speed really low when the screen's off (defaults to smartass governer).
If you wanted to try CM7, gingerbread has a much better battery usage UI that'll give you a nice graph of battery usage vs. time for phone awake time, signal strength, wifi and some other stats.
