Think Gingerbread will improve Thunderbolt Battery Life?

^^^^
I really hope so. Even with custom ROMs, i am not seeing a major improvement in battery life. Phone looks very pretty though.lol
Ive been reading about the nexus Gingerbread update.. and the reaction has been mixed so far.

I'm not understanding everyone's issue with battery life.. Even stock.
I am running the seido 1600mAh battery but its only a tiny bit bigger so..

Yes it probably will. Gingerbread has features etc that will make it better. However, we will not see that until gingerbread kernel source is actually released from HTC. CM7 will be using the kernel from 2.2 until then.

A custom rom won't help battery life that much. What you need is a custom kernel and to tweak setcpu settings. I'm getting much bettery battery life on the 1.5 ghz oc kernel running @ 1.4 and 300 mhz with screen off then I was stock

Custom ROMs will help when we get closer to AOSP. Right now we are just kind of fading out Sense but, taking it out completely should help a little.
But getting back to what you said, right now, custom Kernels are the number 1 way to save battery.

Wait. You overclocked and are getting better battery life? Crazy. I just rooted yesterday, and this is my first day with my set CPU settings. Hopefully it helps, but we'll see.

I don't understand how people think just because the Froyo kernel source came out that we should all be getting 3 days out of our battery now. The INC I had wasn't giving constant great battery life until about 6 months after I got it. It will take time for the battery life to improve. And these roms aren't highly modified at all, it hasn't even been a month, we are all learning about this phone and what it can and can't do. Give it some time and you will see battery life improve, it's not like GB will drop and everything will magically get better.

I don't think battery life is too bad. Better then my old EVO with a larger battery. But I suspect that is because of Sprint's network problems. Made that poor EVO work way too hard for data.

I flashed my kernel recently and created a setcpu profile for 245mhz min/max when the screen is off using "smartass" governor and over all i am using the smartass governor max cpu 768mhz. Battery still kinda crappy. Even just playing mp3s the battery drains fast. Ive been keeping the phone in exclusively 4g and now i am trying 3g. I get very solid 3g/4g coverage in NYC. I donthave many apps running in thebackground. Just have my google sync on and i think facebook... thats about it. Also keep my screen around 20-30%. Ive also done a few full discharge cycles on the battery info and deleted the battery from the CWM recovery menu.
**P.S.- Sorry if i am sounding impatient. I am new to the Android camp. I came from the iphone 3g.iPhone 4 camp. Battery is something i never really had to worry about. Just sucks i have to be more proactive to make my battery last me through the day. Luckily i have access to chargers everywhere... but i dont always want to have my phone plugged in.

Same here, came from the blackberry camp where 3 days per charge is normal. My battery life isn't bad to start with (9hrs) and is only getting better with the new kernel. Still, i think every little bit helps so i hope gingerbread comes sooner rather than later.

In all reality. The screen is what takes up most of the power. I think for me, typically the screen is around 60 - 70% of my battery power. This is a big 4.3 in screen. Having chargers is handy, and the faster the charger, the less you have to have it plugged in. Are there any reliable 2 amp chargers out there?

Ya. Oc kernals usually undervolted and have other battery tweaks. Its setting run real low with screen off. I have my brightness kinda low. Screen off thirty seconds but that's about it. I work in 4g area live in 3g. 4g is tolerable now with this kernel
Sent from my ADR6400L using XDA App

Smartass is still kinda broke from what i can tell. I found luck using undervolted kernels specifically the 1.2ghz kernel from DAS BAMF and Adrynalyne's kernel too

gingerbread seems to have very good power improvements. idle power when phone is asleep seem to be extrremenly low, around 3mA. this is very good and will help you guys when you get GB.

possibly a parallel...
One year age, I bought the HD2 on T-Mobile. Guess what? Poor battery life, etc. Then the update came through and battery life was BETTER. Today, I now am with Verizon and the Thunderbolt. Battery life could be better. And Android 2.3 will be released soon to the Thunderbolt. Will that help battery life. Hope so. But if not, I can get a spare/bigger battery. Admitted, we have no 4G in my home area, so I do not know what impact that has, but my battery life seems like it is improving just because of the charge/discharge cycling that happens normally. And yes, I'm also aware that both are HTC devices but running different OS's, but an update is just that, an update.

I think that it's sad that HTC put in such a low capacity battery and I don't think software optimizations will cure a poor hardware decision. A true OEM 1600 or 1700 mAh battery will make some improvement which seems doable. My Droid 1 had significantly better battery life. If you use 4G as I do, it drains the battery quickly. I use my TB like a Blackberry for email, checking one account every 10 minutes which is far less than Blackberry. Still, using 4G for this, music for my 30 minute commute in both directions and a few other things puts me at below 50% battery life by the work day afternoon. I don't know why HTC put in such a small battery and I'm guessing it has some connection with why they had so many extended batteries to sell on launch day. I have one. Makes the phone noticeably larger, not as bad as I thought although unnecessary... but the phone does last a long time and no worry about battery life.

Android 2.3 is supposed to come to us in Q2, so in the next 2 months. It will more than likely have sense, so it will therefor still drain battery.
My girlfriend pulled 36 hours yesterday on her TB, completely stock. She stayed at a relative's house who didn't have a micro usb cable, so she couldn't charge it. I am pulling a consistent 22-24 hours. IDK what you guys are doing with your phones, but stop it.
I think a big issue with many people's battery life is this is their first smartphone, or first android device. You are going to use it much more than you need to... lol

Wow 36 hours that's unreal I can pull up to 16 hours Max

Are you in a 4G area? I think the 4g is what really eats us alive.

What happend to my battery?!?!

I have 6 (yes SIX) back up batteries for my G2X, because of the Miserable battery life this phone has. Well, I took my phone off the charger at 8am this morning and it's STILL going now at 11PM! Hell, it used to be at 65% at 11AM, this is amazing! I just turned off the vibration for the softkeys and swype, but would that alone return such awesome battery life? BTW, this has not seen the charger all day, that's all 1 battery. Now all I need is a faster GPS fix and working live backgrounds and I'll be happy.

Did u use the internet off wifi?

Are you using stock ROM or custom? If custom what kernel? If custom kernel, OC'd? How about the apps frozen/uninstalled? How bout Root? Do you use 4g or WiFi mostly for data? How about your cell strength, more power required at low signal strength!
The point I am getting at is that many things can cause great or horrible battery life on modern phones. It seems that whatever the phone is, someone will complain about battery and say its horrible while others say its just fine.
I have CM7 installed with Faux's 1.5ghz underclocked kernel. I consistently get around 30 hours of battery life. But I also turn off things when I don't need them and don't install apps I don't need/use. I also have light useage compared to others I am sure.

Battery life is better on sense than aosp.

Is it just me or do i get better battery life on sense froyo roms then i do on aosp gingerbread roms. On aosp i lose anywhere from 7-10% battery per hour, standard use, and on sense i lose 3-7% per hour, standard use. I am on Bamf Remix 1.8.6 with the desense script, and the aosp roms i tried were cm7 and omfgb. I really wish i got good battery life on aosp, it is so much smoother and quicker, but I need my battery to last as ling as possible. Am i alone here or what?

You're going to get better battery life on Froyo over Gingerbread.
What are your setting though, I go all day with pretty good usage (browser/text/facebook/youtube/Music) and I'm always good to go.
I'm running CM7 stock kernel. Display at 40%, 4g disabled when not needed, Wifi disabled when not home and I can't really say I have any complaints.

I thought always thought that aosp GB was supposed to have better battery life.....
I had imoseyon lean kernel on battsaver and ondemandX, wifi off because I'm almost never home, 4g on, all the same settings I run on BAMF. Display at 25% usually unless the sun is blaring.

just curious did you wipe batt stats do a full drain and recharge and see what you got after that?

No, I'm guilty of not doing that. I guess I should try that shouldn't I?

I found the best battery life on Liquid ROM, which is GB.

Can't hurt. I wipe batt stats every time I flash a rom.

Yknow, I'm on the 'stock' BAMF 3.0 rc4 and I'm at 57% after 8 hours with moderate usage, but using juice defender. I also use the OTA Mr2 mod.

There is a simple solution. Get an extra or extended battery, and you won't have to worry about it.

Although that's an obvious solution. There's more he can try before he goes to spend the money for an extra battery. I honestly don't see a need for an extended battery and I play around on my phone all day. When I get in the car charge it. When Im at home on the pc charge it.

I definitely get better battery life on Froyo sense than aosp gb. I, personal, think I get the best battery life on a stock version. I'm currently running the rooted OTA and the OTA MR2 radio and am getting great battery life (4g off, don't have it in my area till the end of the month).
I wish CM7 got good battery life. I like it better than any ROM I've tried, but can't get over the battery drain. It's ok though, I like Sense a lot too.
But you know what they say: To each his own.

to each his own is right
But on the same platform (froyo vs gb) i just dont think you are going to get tremndous variations in battery life. There may be an outlier rom that uses it quickly by most of the roms are in the same ballpark. i think we are talking about squeaking out an extra 20-30 mins which is not nothing but 8+ hours of a battery charge i would be more inclined to go with whatever rom i like best. When GB is released for real, then we may see some improvements across the board.

I have to agree. CM7 has been way better than any other rom i've tried.

CM7 with Kang Bang does best on mine, but you can't compare sense froyo to aosp GB. That's too many different factors. That's a different framework, different kernel structure, different ROM. How do you know what the culprit is?

I'm running BAMF 1.8.6 as well on standard battery.
I just charge at night, take the phone to the car or motorcycle for commute and place on charger. When at work, I have another USB charger with micro USB cable. Charge when at desk. Reverse procedure for drive home.
Battery is great when only off the charger for ~4 hours per day. :-|

It seems that sense battery life is better. I've been on cm7 for a couple weeks now and my battery will be nearly dead by this time every day. So I'm getting 5 to 6 hourz max with cm7. I'm on gingertheory now with dream kernel and setcpu running a few profiles, battery life is at 70%. May have been using it a little less today but still that's a big difference.

Getting the 2750mah extended was the best investment you can make into this phone, hands down. If your phone goes naked, then the difference in thickness is not that bad. In fact I love the new added thickness. It keeps my camera lens off the surface when I put it down flat. Not to mention it adds a certain heftyness that just exudes quality.
Sadly though I got an unlucky battery cover which creeks if you squeeze just a smidge on the sides
Other than that, man is it great. I can go about 48 hours without charging on CM7.1. At the end of the 48 hours, my screen would have been on for roughly 5-6 hours. That means nearly 3 hours of screen on time a day. If you sleep for 8 hours a day, that leaves 16 hours of awake time. 3/16 means nearly 20% of my time awake was spent looking at my phone. Hardly minimum usage, and if its not considered heavy then I fear for future generations. Screw these kids today 12 years old with a smartphone lol. I didn't get my first cellphone till I was a senior in highschool (2004) and even then, it was a crumby flipphone just for the sake of making calls and in case I was in trouble.

What is best ROM for battery life?

Hello,
Anybody who flashed tons of different ROMs, can you comment which ROM provided best battery life for you. I'm not looking for absolute numbers but comparison of different ROMs as far as battery drain is corncerned for the same user.

Is less about the rom and more about the kernel and u/v u/c in my opinion...radio can have an effect too
Currently I am on coca-cola with dag's .3 kernel using the Gideon battery saver script.
I like using that on the quickwiz rom too

Ive been flashing a lot of roms the past week. I'm currently using [ROM][UXKJ2]Buoyancy v1.3.0||Rogers/AT&T||[1/25/12]
Deff the best so far. Very quick and it's been 11.5 hours and I'm at 57%! Kudos to jomeister15 and his team!

You are on ATT network and in LTE enabled zone?

Nexus had the best for me. I also hear Buoyancy is great as well. Sky ice cream sandwhich is what im running now but i charge my phone a lot. An update should be coming soon for battery life fixes on it though.

radio on or off?
I've been running TPC v3 on my 727R for about 2 weeks, with his oc startup script. My battery life wasn't so great until I decided to start turning off data while not using it. Made my battery life go through the roof.
From full charged, I was still at 69% 20 hours later. Mind you, I wasn't using it that much but even still.
Which leads me to wonder: are people actually turning radio off when not in use? Because with it on, I can't get anywhere near those numbers.

What will you be missing if background sync is off while screen is out? everything relying on push notifications will stop working or will be there some other noticeable changes?

I use skyICS and I get pretty good battery.
The pic is of my first battery cycle on skyICS, with pretty decent usage on it. The red little bit at the end is me trying to kill the battery. I had wifi on, data, sync, flashlight, and ran quadrant standard non-stop for about a 30 minutes.
I think a lot of it will depend on how you use the phone. As mentioned above, simply turning off data saves you a lot of power. Going into airplane mode saves even more. I lose almost nothing in airplane mode (I put it on at night). You can get an app in the market that will auto turn off settings for you if you're too lazy to do it yourself.

Extra Heat on Beans

***Just want to clarify this is Beans 6 discussed in this initial post***
Hey guys. Been a member for awhile now, but haven't posted much so can't post in Dev section. I've seen quite a bit of discussion in the Beans thread about clock speed and hot phones, so I thought I would create a quick thread to share my experience and observations.
Unfortunately at this time I'm not 100% sure about my initial observations since I didn't know what I was looking for at the time. But the basics are that Beans uses Imoseyon's Lean Kernel and it comes in clocked at 1900Mhz. The tricky bit was that at first on Beans, I was experiencing the behavior that my settings in SetCPU were not being respected. With clock set at 1512 Max it was still spending time at 1900.
So first thing I did was reflash the Kernel from Imoseyon's thread. Realized it was a test/beta kernel at that point, so was expecting it to not be completely perfect. Not exactly sure which version is in Beans 6, but once I reflashed 12.2, my setcpu setting seem to be respected. Until I plugged it in to charge. Then it once again jumped up to 1900. So I made a profile in setcpu for when on the charger and locked it down to a lower level and it's has stayed at the levels specified in setcpu since then.
Now I'm just using more battery that I want to be, but still have to track down whether is a kernel thing, an app thing, or a phone thing...guess I should have baselined the new phone before flashing...
Anyway, just updated to Beta v0.1 and will report back on my battery findings.

I had amazing battery life with beans. The thing you have to do for sure is lower the CPU. 1.9 is way to much and the phone runs extremely hot. I just started synergy 1.6 and battery script today. I'm going to compare my battery life tomorrow. I recall on beams r6 it took 3 hours of screen off time for me to even lose 1% battery!
The only thing I don't like about beans is the scrolling wallpaper..wish he'd give us a flash to remove it . Also sucks not being able to charge your phone while its off with the custom kernel.

While I'm hoping for better battery life, I'm not expecting anything like that 3 hrs of screen at 1% battery would equate to 100 hrs of battery lift with the screen on. No, I'm just wanting to get less that 1% an hour drain at idle. It bugs me when the phone drops so much at night. I never did a good test on Beans 6, but there were a couple of night where in a 7-8 hour period it dropped double digit percentages....up to 15%. But I also found later I was battling an occasional wakelock issue. So I wanted to wipe and flash and try again...
So, when Beans 7 dropped, I did just that. Loaded it up last night and forced myself not to restore apps until I got some baseline information.
The initial clocks in the kernel seem good... As an aside, I almost want to install Beans 6 again and see if the overclock happens initially or if it had something to do with restoring SetCPU with data from my previous phone... This time I restored App Only and clocks look good. Even when charging, no extra profile needed like with kernel Test 12.2.
Idle battery life with just a couple extra apps installed was acceptable. Lost 6-7% over 8.5 hours. I was thinking stock was better, but now that I think back on it, the only night I was pure stock I didn't get to bed until 3am. So it lost, I think, 4% in about 5 hours...So given my fuzzy memory on the numbers, probably about the same at idle, maybe a little bit better with Imoseyon's Beta 0.1 Kernel...
So I've restored apps now and will fuss over battery life and other stuff for a few days more and then settle down and just use the thing.
Final note. Beans 7 looks awesome. The 15 toggle and notification looks nicely polished. Gone is the little nagging issue of having trouble grabbing the notification bar. So thumbs up all the way around so far...:good::good:

Im on beans b7, currently running stock settings...my device is running at 30*c, and my battery life is at 23hrs @ 49%. 1.5hrs of screen on time.
