Crappy Battery life, try this! - Thunderbolt General

So I had just gotten done posting a smartass remark about how I had gotten two days on one charge with my phone, only to pull it off the charger go to work, and have the sucker die in 4 hours.
I figured out what I did, and you should try it too, it may help you out. I am running the leaked radio btw.
So earlier today I decided to go into ##778# and type the password 000000 and then modem settings and rev A and change it from Enable to eHRPD because I figured with the 4G network back I could use the dual radio 3G network. Well That is when my battery life went to ****. I pulled my phone out of my pocket to it burning hot and at 9%. I quickly changed it back to Enabled, and it survived the 9% all the way to 5% over a period of another 6 hours.
So unless you need to talk and use data at the same time, use the regular 3G network like I am, and see if your battery life doesn't improve. I still am on 4G all day, but this was literally the only feature I changed on my phone between amazing battery life and crappy battery life.

You can still do talk/data at the same time on Rev A with 3G.

Right and at the moment, no thunderbolt should have eHRPD. No matter what verizon says. So we're all running on rev a right now, and you must have done something else. EHRPD will not waste your battery any more than normal.

Actually mine is set to eHRPD. Just bought it from Vzw a few days ago, rooted and flashed DBamf 161 along with the new radio and Im still set to it.
Making me think I should switch it hmmm.... hmmmmm

I just checked mine and it was set to eHRPD by default. Does this mean I should change it to enabled or leave it alone?

It doesn't really matter what it's set to. It seems as though Verizon has made all Thunderbolts default to Rev A in 3G areas after the outage rather than eHRPD regardless of what the modem setting is. You can check under About Phone-Network-Mobile Network Type

I use the LTE on/off app and Juice Defender Beta to increase battery life.

Set my phone to eHRPD then rebooted it and it went back to enabled I think Verizon is doing a tower by tower fix.

Mine is rooted and I get almost 2 days of moderate use out of it. Its the only way to make this phone truly great.

what kernel/governer do you use?

I'm running das bamf 1.6 remix with the stock radio and the kernel it came with. I know that it isn't really necessary to wipe but I did. I used a battery calibration app and auto brightness.

I'm currently using Tesla Coil 1.7.1 with imoseyon's batt saver kernel, setCPU using the smartass governor.
Today my battery life was absolutely horrible: 6 hours from 100% to 19% with 1 hour of screen on time at ~25% brightness, 8 mins of call time and maybe 2 hours of music off of my SD card.
I just can't figure this phone out...

I have noticed that as well. Some days my battery rocks, and some days it sinks like a rock. Not sure why. It's as unpredictable as my wife! LOL
sent from my B.A.M.F Thunderbolt

The other thing I do is if I know I am not going to use my 3G or 4G connection I turn it off until I need it. This Rom I use has a widget for switching it on or off.
sent from my B.A.M.F Thunderbolt

The battery sipper kernel is the only kernel for me. Using the same Rom I went from about 6 hours of constant 4g to over a day of 4g. I do have the extended battery. I leave 4g on ALL day and get more battery life than I did on any other phone. I love that Damn kernel.
Sent from my ADR6400L using XDA App

So does changing the modem do anything or not? I just checked and my Rev A setting is eHRPD and under about phone, it says CDMA-eHRPD. I have not changed anything other than turn LTE off when not needed, and when I turn it off I select CDMA auto (PRL). I am using the new radio and BAMF 1.6. I get decent battery life so I am not too concerned, but I am curious.

Battery. LoL. 2G :-)

Kind of random, but to those who are looking to save your battery life. Just run in 2G mode until you need the speed. Somehow, I have been unplugged for 5 hours and am at 90%. Normally, I'm at 40 by now. It was either that I installed Sidekick (doubtful), or the fact that I forgot to turn the phone back to 4G when I lost service last night
Just thought I would share, I got excited to see my battery isn't draining like a fat kid finishing off cake that I had to share (the info, not the cake)
Have you tried flashing your kernel? I leave my 4g and wifi on all day and I still had 97% left after I got off work and the phone being unplugged for 10 hours. I surfed for a bit and downloaded a few apps at work too. I'm running ultimate glacier with the smartass kernel running overclocked at 1843mhz.

Only 6 hours battery life

running das BAMF 1.7 and the lean kernel i am only getting 6 hours at best with what i would consider as light usage. when i am actually using the phone i get about 1% usage per minute. any ideas as to what is going wrong?
If you're on the standard battery then nothing is wrong, that is common.
What I do is keep my mobile network (4G) off as much as I can. My battery is a lot better when I do that.

Use wifi as much as possible. Shut off data when not using. Don't use 4G unless needed. Minimize screen on time. Turn off autosync. Switch to a different kernel, etc. Juice defender really helped me, also. Make sure you set your CPU to minimum when screen is off. Two days probably isn't realistically possible with the stock battery, but you can probably get more.

I use juice defender and then also LTE on off and only run in 3G. I get easily 15 hours with 60% battery left
I'm not in a 4g area, I get about 12 hours with 3 or 4 hours of screen time. Stay on WiFi as much as possible. Try calibration the battery.

Sounds like an issue with the software, more specifically the kernal. Are you rooted and running a rom/kernal combo? If so, try reflashing. If that doesn't work, try a new combo.
I've found a happy medium that I can live with... getting anywhere between 10-16 hours with around ~2 hours of screen time.
Running bamf stripped 1.7 using its stock kernel with the smartass governor and underclocking to 368/245 when screen is off.

Saving battery life

Hi all.
Looking for some serious help. Coming from a Samsung vibrant. I need help with how to save battery life on the sensation. I have been off charger for 5 hours and 51 minutes and am down to 41%. Is this normal? I have been only texting really. I got my data from battery monitor.

It all depends on what you're using the phone for. I'm at 55% after 12 hours. yesterday I got 17 hours. if all you're doing us texting then no,thats not normal. but I suspect you're probably doing more with it than you realize since its a new toy.

Stop Android from phoning home and you'll save greatly on battery life.
Best way I've found to prevent battery drain, is to stop Android from phoning home.
Once you use an app like Autostarts to stop unnecessary things from starting up all the time on their own and also block a couple ports that are not always needed via an app like DroidWall, you'll see great battery life. Also see other details in that link of things I turned off to increase battery life amoung other benefits.
For now, I can only speak for seeing the difference while using a Nexus One ROM on my HD2, but I have way better battery life, GPS lock times and faster device boot ups than ever before.
This is yet another one of the reasons I must wait till the Sensation is rooted and unlocked. Because I'm not using it while it's running things I can't better manage, so they don't drain my battery.

Well to be honest for the 8 hours I'm at work, I use it light. texting, a few calls and about 30 minutes of reading pulse and playing games. However the next 8-9 hours I would consider moderate to heavy use. I have no monitors or anything running, just running straight out of the box.
I'm at 34% after 14.5 hours today.
I charged it fully the first day, ran it to 0, then charged it fully again last night.

I think mine's even worse. Phone was off charger at 100% at 11am, by 1:30PM it's already down to 80%ish. By 4PM it was down to 40%ish, got it charged up to about 70%ish around 6PM, by midnight I was around 6% again.
So I think I'm losing around 10%/hr. That's gotta be abnormal, and the battery gets really hot too. At the moment, I have several speculations:
1. Death grip causing the phone to work harder to find signal, and tmo's coverage kinda sucks in my town
2. I have defective unit/battery
3. Some apps behind the scene are killing it. But I've checked what's running behind, even turned off unnecessary stuff using autorun manager. Auto sync is turned of only for gmails. Weather, IMAP mails, pulse, facebook etc are set to pull in couple hrs instead hourly. The battery life cannot be worse than my 2-yr old HD2.
Hey guys. Have you considered bump charging. HTC advised the idea for the HTC desire battery and it in most cases doubles the battery.
Sorry I can't be more specific bit I'm on my phone. I have found the relevant link. Read the 1st post. I'm gonna do it when I get in from my gig.

I'd suggest uninstalling battery monitor. I had installed it on my g2x and immediately saw my battery percentage drajning more quickly. Probably because its always running in the background.
The best tip I can give for better battery life is to minimize what you allow to run in the background. Get rid of any task killers, set Facebook/Twitter/Email/etc to sync less frequently, turn off wifi if you're not using it so its not scanning for networks, and so on.
Also install juice defender from the Market. Its free. It has greatly increased my battery life.

I installed the Plus version because it allows wifi control. I just use the default settings except I change so it doesn't disable wifi. I do that because I use wifi calling at home so I dont want Juice Defender turning off my wifi. I always turn it off manually when I leave the house anyway.

Charge vs. Thunderbolt

Don't know if anyone's interested, but here I go:
Bought a Thunderbolt back in April and have had it replaced 7 or 8 times for various reasons. Each replacement, I've also had intermittent issues sending email from my POP3 account.
I demanded a Rezound, but they only gave me a Charge. Here's the comparison:
Speed: Charge wins EASILY. I expect at least 20 on the charge and hope for at least 10 on the Thunderbolt.
Weight: Charge is MUCH lighter. I like that.
Display: Charge wins easily. AMOLED is fantastic.
Screen: Charge. I love the way the screen feels. Much smoother than the Thunderbolt at times.
EVERYTHING ELSE: Thunderbolt. It's "quicker" overall, more responsive, GPS locks in within seconds (Charge took about 5 minutes), phone pad is more user-friendly and didn't require as much reaching from the thumbs, Thunderbolt NEVER freezes (Charge did), no longer randomly reboots (Charge did), camera sends portrait pics right-side-up (Charge doesn't), and I'm sure I'm forgetting something.
I should point out that because of its positives, I really wanted the Charge to work for me. It was a VERY hot chick. But it was not a wise choice. So for functionality, I'm sticking with the Thunderbolt. Just gonna deal with it not sending mail intermittently.

Rooting is the only way to go for the best possible experience.
I had a Thunderbolt, Revolution, and Charge so I have experienced all of them and will have to give it to the Charge as the best overall.
Thunderbolt was the only Android phone I had fail on me after 3 months of use. It also is considered a dud, with countless complaints from reboots, to radio issues, and so on.
It has a worse GPU/processor
Hardware buttons are TERRIBLE. They are mushy and flush, which doesn't sound like a big deal, but to me it's very annoying every time I use the phone
No hot-swappable SIM/SD
Less battery capacity 1400 vs 1600 and also by far the worst battery life of the three.
Hardware keys>capacitive keys
Thunderbolt does feel better in hand and I like the design.. I also am envious at the development/ROMs the Thunderbolt has, such as MIUI...
the only thing I'm jealous of the Thunderbolt for is the notification LED... I like everything else on the Charge (except the damn data drop which still happens occasionally for me ), and am content with the amount of dev work we have though admittedly little

Yes, if you root and download "FasterFix" your GPS will be much better. Although, it doesn't work for some people so you might need to edit a file in your /system. Either way your GPS will be much better. Rooting is insanely easy, you plug your phone into the computer, run a program, reboot, install a file and bam, you're rooted. Just check out some of the guides in Development. Also, don't feel chicken to root, we have the files needed to completely fix a bricked phone(unless you happen to brick it while messing with Voodoo Lagfix, which with our current ROM/kernel choices is almost impossible, and even then it can be fixed 99% of the time).

Install Imnuts' new PBJ kernel(its posted on Rootz) in CWM, then install Voltage Control and mess with your voltages/CPU clocks to your hearts content, although I warn you, never go over 1.4GHz or you run the risk of frying your CPU since anything over 1.4 heavily overvolts which is a very big no-no.
That's helpful...thanks for the advice. I've never rooted before, but that's quelled some of my concerns. I should mention that I'm getting some INSANE download speeds here in Kansas City...usually north of 23 and up to 49. It's great. I'm having issues with losing data connectivity (altogether) which requires a reboot. Other than that, I think my phone is getting used to me and adjusting accordingly.

I lose 3G data for days and I am on my 3rd phone. The last replacement lasted 2 hours before the data dropped for 10 hours.
It's weird, I think some Charges have data issues possibly due to quality control the either the 3G or 4G basebands or both, whereas other Charges don't have issues.
I can personally attest to having a reliable charge, although I rarely go to a 4G area.
I live in a solid 4G area but still the data droppage on mine is horrendous, problem is that its not reproducible in store because of their signal boosters so no go on a replacement (I don't like dealing with the reps on the phone either, most don't know what they're doing and I don't wanna call 50 times just to get a good one lol)
I'm saving up for a Nexus or I might wait for the next HTC superphone, either way I like my Charge a lot but the data issue on mine is a deal breaker otherwise I'd stick with it till my upgrade

Unfortunately I heard that it's not just a Charge issue, but a Samsung issue. Just from reading online articles it seems that the Nexus has the same issue. At lease it did with 4.0.2. I dunno about 4.0.3.
It is a Sammy issue. A lot of people came from the fascinate to the charge for just that issue.
We had 2 fascinates in the house bought at the same time. Mine dropped once in awhile the other was solid. I got the charge as a replacement and it has been very solid. My wife has a stratosphere and she loses data once in awhile but a quick airplane toggle restores it. It is a weird issue and must be in quality control, though the fascinates issue was resolved with a software patch eventually

Battery life

This is probably one of the worst phones on battery life that I have ever had... No matter what I do, what tweaks I use of what rom I'm on... I always only get 7 to 8 hours of battery with 1 hr screen on time.
I honestly have no idea what to do... I'm so sick of it. Anybody have any suggestions?
Seriously?
I have been on my phone all day with a full charge and I still have about half the juice. I am on stock 4.0.4 ICS. The one that droidstyles has in his guide. The Rom that came with my phone sucked on battery. This Rom works great for some reason.

What are your settings on? Post your settings (like screen, whether GPS is on, ect), a lot of times it has to do with your settings. I used to have so-so battery life but I tweaked some stuff in my settings and am very pleased with the phone.
Believe me, if you want bad, try the Droid Charge. Worst 4g phone I have ever had in terms of battery life.
This is on clean rom. Ignore the screen percentage, going down since this was a recently flashed rom.

Possible Idea
Don't know if this problem could occur with different ROM's, but I had issues with a runaway process that kept showing up. Maybe try Developer Options -> Show CPU Usage. I noticed that one called gsiff_daemon kept showing up at the top and was making my battery drain extremely fast. Everyone on this forum said it was a common issue and that it wasn't a crucial file, therefore I should just change the name so it wouldn't get accessed.
On RLS7 and kt kernel? This kernel has capabilities for overclocking/underclocking & overvolting/undervolting. By default your min Mhz is set to 384. Go into ktweaker and lower it to 96, test your phone out with a scaled stress test (play store app for stress testing). Then you can also go into the extra settings of ktweaker and set the Mhz for when your screen is off in addition to the governor (many options of which some are powersaving labelled).
If you want to save more battery read the kernel's thread to see starting undervolting values and lower from there while testing your phones limits. More undervolted you are, the less battery your phone uses for that particular frequency.

You obviously never had the thunderbolt, now that battery sucked. You have to let the rom settle in and your battery will improve. Usually for me the first day not so good after that everything is fine.

I had a Thunderbolt. Yep, now that was poor battery life.
My S3 gives me 12 hours if I use it heavily. Typically, at 16 hours, I still have 40% remaining. I leave WiFi, bluetooth, and GPS on 100% of the time.
As bad as your battery is, I would suspect that you have a poor radio signal.and the radios are cranking up the power to work. Try using WiFi or turning off mobile data for a while to get the LTE radio turned off.
man, i barely get 8 hours at times

This is probably one of the worst phones on battery life that I have ever had... No matter what I do, what tweaks I use of what rom I'm on... I always only get 7 to 8 hours of battery with 1 hr screen on time.
I honestly have no idea what to do... I'm so sick of it. Anybody have any suggestions?

This. For example, I have a 4g tower nearby at work, normally (4-5 bars). But sometimes it disappears, and I end up on a 1-2 bar 3g tower for the day. On those days, my battery life is around 8hrs max, barely using it. On good signal, even with crazy heavy usage (4hrs screen on and lots of 4g web browsing) I can get over 8 hours.
Signal strength has a LOT to do with battery life.

Check your Google account sync - could be something in there is not syncing correctly. Settings / Accounts / Google.
I had this - Internet Sync was not working but kept trying burning CPU, network, and battery. Disabled the failing sync and all was better.

Is it switching between 3 and 4g a lot? Constantly searching is rough on a battery.

I seriously doubt you guys are getting 7 plus hours of screen on time with the stock battery. If you are then you are charging it at some point.

I am using stock battery on stock jellybean leak and get 30+ hours with 5.5 to 7 hours screen on time you can see from the pics above that we are not charging. The bar would go UP at some point if we were.
I just have my phone set up the perfect way to get maximum battery life.
It's simple. I personally have nothing to gain from lying about something so silly as battery life.
