tips to improve battery? - Thunderbolt Q&A, Help & Troubleshooting

right now im running cm7. I undervolted my phone and I am currently underclocking it too. What else could I do besides the typical turn off your data, brightness, animatoins etc.?

Right now I'm on an extended battery but before that, used all theory cm7 aosp based ROMs. His memory tweaks to the kernel are ridiculous. But one thing that helped a lot was using an app called automateit. Works like green power or tasked but better for me.
I have it set for 3 seconds after the screen goes off, I kill all mobile data. Then when screen goes on, it turns mobile data back on. This does not effect txt messages and phone calls.
Reasoning this works is because I found the 2 main battery killers to be cell standby and screen brightness. Part of cell standby is when your phone is searching for a data connection consistently. For example when. I would go to the movies, my 4g/3g was horrible. I'd go in with 80% and by the time i left it would be at 20% or less. Same with wifi but much easier to turn that off. So during my work day I would keep the app on, keeping my screen/data off, but when I wanted to see my mail, I'd turn screen on and it would sync instantly. Obviously if u want to get your mail randomly even with your phone off, there are settings you can tweak.
Aside from the cell standby issue, it'll also prevent your phone from constantly syncing.
Its a little harder than green power to use but it works all the time.
Aside from this use, there's countless other ways it can automate your experience.
I chose Trigger: screen off, and subsequent Action: mobile data off. Then trigger: screen on, action: mobile data on. With timers for each.
Last is screen brightness. If you get good data and cell reception then screen brightness will be the #1 cause of battery drain. In most cases with the bolt, its #1 regardless.
I just put it to 30% or 40% with widget. Sucks because its a killer screen, but at 75-100% brightness, you'll expect massive battery drain.

God... the world is upside down when THAT statement makes sense, but it actually does. I have to really flog the hell out of the Tbolt running Sense to kill it in 8 hours. My girlfriends dInc running CM7 pretty much never last as long as mine running LTE.

On my brother-in-law's Thunderbolt, I moved him to "CL3ANTH3ORY_V1.0" which is GB and started using SetCPU. We also upgraded to the 627 radio set (CDMA+LTE) and now he can get through a whole day without a charge. Previously, he was charging 2-3 times a day. He is a pretty heavy user though, but still a great improvement.

Trigger 3.3 beta

I just installed the new Rom TRIGGER 3.3-beta. This rom is very fast and the GPS is great. I also put on bali 1.8.4. But the battery drains fast. If you guys tried it out, and found a way to save battery can you please let tell us what you did to control it. I know its in beta version and is being tweaked on.
Thank you
Yea Im using the same Rom. Hate to break it to you but the battery life on most all android devices sucks. I have had 5 different android devices and the battery sucked on all of them. didn't matter if it was stock or custom Rom. ether way these devices just have ****ty battery life. You can make it a little better by turning down brightness and messing with other settings but when it comes down to it. it still sucks! Just my 2 cents!

Did you recondition your battery after flashing? I've had pretty good battery performance with the Bali kernels. I also tend to use the KB1 modem. It seems to give me the best battery. But each phone is a bit individualistic, and what works well for someone may not work as well for next person.

This is untrue as I have owned an android device since the G1. The battery did suck on the G1, but by no means does the battery suck on every android device. My guess is you probably never calibrated your battery or you just used it very heavily. There's also the possibility that every rom you tried sucked on those devices. I have consistently gotten a full day or more with Bionix NextGen V2 with the Bali kernel with moderate to heavy usage. It is true if you lower the brightness,turn off wifi,bluetooth and gps when you aren't using it that it will increase your battery life though.
I have reconfigured the battery and have the brightness turned all the way down. Dont use WiFi but battery still sucks compared to other smart phones.

can any of you post a screenie of this rom pls
Battery usage is hard to compare since there are so many variables. In my experience I generally have better battery life when visiting my parents. The area I live in is somewhat of a black hole for signal and I notice more battery drain here with the same rom/kernal setup and similar usage pattern. I believe the weak signal here causes a higher battery drain over all.
Of course this might not apply to your situation but it could be worth considering.

I'm not going to argue with you, I'm just going to state what the facts are.
THE BATTERY DOES NOT SUCK, MOST LIKELY IS USER ERROR
Lol. It isn't user error. I think you might just use your phone more heavily than others. One thing you have to realize when comparing the battery life of the phones are a) battery size, b) screen size, c) smartphone or stone age phone, d)**** you've done to the phone including ROM's/Kernals/Apps/Sync.
Personally, on days that I am working, I get about 8-10 hours out of my battery before it dies. When I am not at work I get about 23 hours out of my battery.
what is the major difference between trigger 3.2 and trigger 3.3?
Try using overstock instead, I've had pretty good battery life with it.
Im running trigger3.3 beta with overstock and the battery is great.

so any new tricks that you guys have found to boost up this rom?
might try this later, i could say the battery on my vibrant is better then the iphone and ive gone through all versions of the iphone.

bahaha you must be kidding. like someone else said, it depends on soooo many variables and phones. I was running trigger rom and overstock kernel and was going down about 1-2% battery every hour while screen was off. I listen to pandora every morning for an hour to hour and half and would go down 5%. I've sat on the web watching tv on TV shows stream app for about 1-2 hours and went down like 15-20% when brightness is lowered.
It's all about the brightness, killing apps that enjoy sucking battery life and enjoy run constantly, and running an OC/UV kernel. You can also change it from the usual 3g/H connection down to E (edge) which uses alot less power also. Turn off or turn down auto sync on certain apps like facebook from every 10 minutes down to every few hours.
The screen is the biggest power consumer, so lower that, set it to automatic or all the way down to lowest brightness to save quite a bit of battery when using the phone.
Usually the second largest power consumer (if ur not a huge user of just one certain app) is when the screen is off and the phone is syncing and just running android. the solution is If you can find a decent UV kernel (overstock for android 2.2 was what I was using when on 2.2), you can slow your CPU down. Like on my vibrant I made a profile (on the SetCPU app) to undervolt it from 1,000mhz down to a conservative 400mhz max and 100mhz minimum when screen is off. This is very easy to do. sometimes I'd watch shows on that. I usually left it at a conservative setting and 800mhz and 100mhz min all day long when screen was on, sometimes at 400mhz if i wasnt doing much. It worked wonderfully for me.
Moral of the story, there are plenty of things to make your phones battery last longer than it normally would. The big one probably to get a well known kernel that can UV, then get SetCPU and make a few profiles to make your phone use less power.
BOOM!

Poor battery life?

Anyone else getting poor battery life with their Razr? I cannot go a full day without recharging at some point. I need a phone to last at least 16 waking hours, so I can recharge at night.
My typical usage pattern is a few hours a day of web browsing and email. I don't game, and I rarely stream video or do anything data intensive. GPS is switched off unless needed, and my screen brightness is set to auto.

I'm actually getting pretty good battery life compared to what I've read so far... Though it wasn't 16 hours, I DID get almost 12 out of it yesterday with pretty heavy usage all day.
I highly suggest using the task managers auto end feature. It'll turn off any apps you set it to after 2 minutes. Fast Reboot is also a very good friend of mine. Though I haven't set any yet, I've played with Smart Actions, and I think with some tinkering, it'll work wonders as well!

JuiceDefender with root, AOSP helper, and a manual setup is extremely helpful. The data disable override feature should be on as well.
Make sure in-pocket detection is OFF, as well. It kills the battery really really quickly.
As far as smart actions.... Just turn on the premade battery extender and nighttime battery extender. And data off on screen off.
Lastly, screen filter from the market helps a lot.
I got a full day and 2 hours of use today on Wi-Fi. I'm sure on 3G I could get 20ish hours, and on 4G I could get 15ish.
Mine is great. I got my phone yesterday so it isn't fully calibrated yet but it still last very good.
I've found that the the biggest drainer for me is being in an area where 4g/3g is flip flopping alot. Other than that, phones got amazing battery life. Especially on wifi.

What has always worked for me is to use an app called brightness profiles. My phone lives at 30% brightness 95% of the time. The RAZR has a super bright screen, 30 is plenty.

my gf just got her razr a week ago and says with regular usage she gets about 4 hours of battery life. thinking about returning it for a different phone or maybe she got a dud? she doesn't want it rooted so I did everything else mentioned. if there are more tips I'd love to hear them before the phone goes away for good.
Turn all haptic(vibration) feedback off. i get about 20 hours on 4g, all apps in auto end list, i don't have any BS apps that like to run randomly, not synced with my fb,twitter, g+(have my laptop all day so no point), brightness is about 30%, smart actions usually kill my batt faster for some reason, gps is on, timeout is 30 seconds. I text a lot, and about 2hours of phone calls perday

Put the power control widget on your home screen.
Set brightness to minimum or lowest setting that you can use well.
Use wifi whenever possible. Turn. Off new network notifications.
Turn off animations.
Use a simple, mostly black wallpaper.
Turn off auto data sync.
Since I'm around wifi all day I can easily go 12 hours without a charge and have plenty of battery left. 4g is a total power hog.
If you're outside you might want to buy the power pack... good luck!
I think typical android battery life for a normal use will be varies from 6~20 hrs depending on the way u use and what you use.
when running only data/wifi when i need it(off data/wifi when not using), i can get more then 20hrs. if i on data all the time, i can get 8~10hrs with with some facebook, emails and lite web sufing. i will get 4~6 hrs on heavy use on gaming, video and music.
but u need smart action, task killer and ti backup to really optimize the battery life.

yeah.
battery life is a hard problem for android device for a long time.
but i can use some trips, for example.
1. using the task managers, it can kill some app that you used.
2. using the app called province electricity king or the same function app.
3. turn off the back-data auto sync

My Razr has a very good battery life after a few cycles of charging and discharging.

Will the people that get awesome battery life share what they are running?

I've tried a bunch of different combinations but I have gone back to GB every time. I don't even care about features anymore I just want to get the most out of my battery life. If you are getting great battery life will you post your kernel, firmware, and ROM please? Please post if you are on Ext Batt or not.
Thanks
I have an extended battery and I think my battery life is really good. Primarily, I turn off most automatic syncing and keep my screen turned down as low as possible at all times. I use a widget called Brightness Level and I keep it at 13% most of the time. I also keep GPS, Bluetooth, and WiFi off unless I specifically need them. Other than that, I'm not doing anything special. I'm on Clean ROM 4.5 Standard.

I think the biggest culprit is the screen. I'll get varying battery life every day, anywhere from 2 to 12 hours on a standard battery, or 4 to 30 hours on extended.
The only common factor in each of these for me is screen-on time. I'll get 1.5-2 hours on standard or 3.5-4.5 on the extended battery before it dies.
However, as previously mentioned, turning off Bluetooth, wifi, GPS, mobile data, and sync will always help battery life. Too bad I rely heavily on some form of data, email, and Bluetooth headsets for my work.

All in my sig.
I've got a system...
I usually can get through the day with a regular battery; a few things to remember:
1) Mail/messaging/anything push
if you can deal with it, set peak hours from like 7am to 7pm and get stuff every two hours during peak and every four hours during off-peak. Push means your phone is actively waiting or doing something almost all the time. This one single thing will make the biggest difference, except for...
2) The Display
The biggest energy hog of all. Actually not much you can do here but set it to time out quickly (a minute or less) and set to either auto brightness or remember to turn it down indoors.
3) Audio
Running audio through the speakers also uses more battery. Try headphones.
Bluetooth audio is great but again bluetooth also uses more energy than headphones.
4) Networking startup services
Lots of games install startup services that run constantly in the background checking for data from the mothership and/or other players. Get rid of them or turn them off if you can. Some apps also do this, I dont have a list but a little Googling will enlighten you.
Any other tips? I'm always looking for other (reasonable) ways to save battery.
PS: as you probably know, the phone (and any smartphone) will charge about %500 faster if its completely turned off. Common sense, I know, but you'd be surprised...
this will keep you going all day:

Seriously though, if you actually use your phone throughout the day, its probably better to just get the extended battery. Anytime you turn the screen on, it sucks battery.
You can try juice defender. I have it set to extreme and tell it which apps can turn on data with and without screen on, so 4g is only on when it needs to be.
I've heard ROM toolbox can keep apps from opening in the background but haven't paid for it yet. This would be good for games like draw something and WWF that seem to suck power constantly.
Thanks for the replies. I changed my power from performance to normal and that made a big difference because the phone won't sleep in performance mode. Just a note it will still sleep data even though my hotmail is on push. I am using the hotmail app not the htc mail app. I see people with 3+ hours of battery life in the battery thread and I don't see how they do it. I have the extended and I can make it through a day but I only use the screen for under an hour it seems. I'm not really seeing anything new in here I'm not doing but I do keep my screen auto a lot so I might jack that down. I keep every feature off when not in use.
I'm using stock rooted 3.14.605.5 with same firmware and over been getting better battery life since flashing.
I'm mad as hell about losing unlimited data!

Man, That's some serious ****
I generally get great battery life-around 4 hours screen on, 4g, gps. However, a few days ago I noticed higher than normal temps, and poor battery life.
So what changed?
I traced it to the installation of one free app. Picsart-uninstalled and everything is peachy again.
This is my second rezound, the first one always ran hot and drained the battery.
If you're having problems with heat and drain, run a full ruu and see if it helps, if not you may have a bad device or possibly a bad sim. I don't think that the device is the problem in most situations. More likely a runaway app, bad radio/firmware/build combo, user error, or expectations too high.
My setup:
Latest ruu-cleanrom de 1.4-take it easy on the apps and widgets!

Your issue may lay mostly in poor reception. I notice your signal strength thing is in yellow most of the time. Use WiFi if you can. I get pretty good battery life on
Ineffibilis GB
Feb OTA firmware. Don't remember the numbers.
Dsb 1.1.3 undervolted by about 100mv via incredicontrol (UV depends on the device, each is diff) and under clocked to 1188mhz and with interactive governor.
I think my power setting is on Normal.
Also I have weather sync every 3 hrs. Facebook every 4 and leave my Gmail accounts on sync.
I get between 3.5 and 5 hours every day of screen on time through out the day if I'm using my phone a lot. This would also be coupled with usually around 30 minutes of phone calls too. But usually I only charge it every other day (when it gets to around 30%). I get more time out of it on WiFi (5+ hrs and less on 4G (3.5 to 4 hrs at most throughout the day). I also never run my phone down to less than 20% if I can help it. I'm on stock battery too

That battery life isn't great if you're only using 9m of screen on time. 60% after 5 hours isn't unusual for me if I have medium usage of my phone. Like platinum mentioned, your signal is terrible. The Rezound (and most phones) tend to use a lot of battery if they're trying to constantly find a signal.
Right. Battery should only drop 1 to 2 percent per hour on good signal. Bad signal can kill it... If I was on 3G my phone would be around the mid 90s with the same usage.

Does it matter if I turn off data or it will still drain looking for cell signal?
As long as you don't have partial wake issues, there are only two real concerns for battery.
It's not processor. Again, if the phone's not 'awake' while the screen is off, your phone's processor is not ramping up to full speed at all. While it's on and in your hand, 1.5ghz is a great speed for it to operate. Slower speeds than that significantly slow down how your phone operates, and you will have your screen on for seconds longer (Which uses WAY more battery than the higher clock speed).
In Facebook app, go to menu > settings > and change the refresh interval to NEVER!!!
As of Android 2.2, Facebook does push notifications. You don't need Facebook refreshing very 4 hours (OR EVER!). This wakes up your phone (ramps up processor speed, and so on), uses data (battery), and is unnecessary (since you get push notifications anyway). Turn that crap off. Same with Twitter. Turn it down to manual refreshing only (look in settings > accounts and sync as well as in the app). Same with Friendstream (which will automatically have its own refresh settings - fix them).
There are two things that use your battery.
1 - Screen. Turn your screen off when you're not using it. Stop turning your screen on every 12 minutes to 'see if you have any notifications'. Trust the green LED blinking light, or listen for your phone. You can stop checking it. You're using a TON of battery lighting up that 4.3" screen AND waking the phone back up (ramping up the processor, among other things, and it will stay awake for at least minutes, even after the screen goes back off).
2 - Data. Turn wifi off if you're not using it. Turn Mobile Network (GASP!) off when you're not using it. Pull down your notifications and hit Quick Settings, and turn Mobile Network off. Don't have that? Make the HTC Widget > settings > Mobile network. Turn it off when you're out with your friends after midnight. a) you're not going to post anything reasonable or coherent when you're out drinking anyway to Facebook, and b) call and text still works, so you can still mack on honeys all night (and text them drunkenly). You don't need your damn Gmail at 1am. I know you don't. Don't try to convince me otherwise.
If you keep your screen time to a minimum (and brightness down if you're not using auto brightness), and TURN OFF mobile network (internet) when not using it, your battery will last DAYS. Yes, the stock battery. Now, do you do 100+ texts per day? Sorry, your battery is going to die today. And tomorrow. Every day. The screen time murders the battery, and the Wake time that your phone will have as a result (like every time the phone lights up - for minutes at a time, it'll stay 'awake').
That's how you keep your battery going. On any android phone. Yes, an extended battery works great. I bought one (half price in a verizon store) AND got an EXTRA one for $4 (on amazon.com). Yes, it's for thunderbolt, but YES it's the same part number. It's running my phone right now. Keep it charged, and in your glove compartment. Your life will be better.
http://www.amazon.com/dp/B0055OTNK4/ref=pe_175190_21431760_C1_cs_sce_3p_dp_1
Go get it. Turn off your internet, and your screen. Trust your LED notification light. Stop using MMS Screen On. Your battery will last all day, every day. Unless you text a lot. Then, good luck.

In short, yes.
If u turn off data it will help. But you will still have poor signal, so Idk how much it will help. apps and processes that use background data won't be using it, that alone will keep your phone from reconnecting so much, so it will help.
It takes your phone longer to connect on poor signals and your speeds are slower so it takes longer to do the same things. This also keeps your processor running faster for longer times.

Why is battery life so bad on the Rezound?

Currently running Clean Rom 1.4 Senseless and just did S-Off.
I bought a extended battery due to the awful battery life but still I am getting really bad overall life.
I am coming from an Incredible so I am use to good batt life but is it basically due to the screen and dual core processor? Kernel? Rom?

Software combos can make huge differences but, if you get bad battery life on an extended battery, its's either user related or you keep getting bad batteries.

Currently running Clean Rom 1.4 Senseless and just did S-Off.
I bought a extended battery due to the awful battery life but still I am getting really bad overall life.
I am coming from an Incredible so I am use to good batt life but is it basically due to the screen and dual core processor? Kernel? Rom?

upgrade your firmware. its been said the newest firmware is showing better battery life then ones before.
you are s=off so what i would say is to run the latest leaked ruu.
if you arent to comfortable with it you can follow these steps:
1. back up rom, user data
2. back up internal storage (ruu will wipe it)
3. place latest ruu zip on the root of your external SD card.
4. flash it twice, first time will be super fast the second one will take the longest.
5. flash or fastboot your recovery of your choice back to the phone.
6. now this part is up to you, you can restore the rom you are currently on or flash it over and start fresh. ( for me when i restored i was having problems and random FC so i did a wipe and started fresh)
Hmm I'll probably do the firmware upgrade. Also does 4G LTE require more power from the phone than 3G?
Also yes I do stream a lot but I always have my screen off.

Yes, it uses a lot more power. You can save power by using wifi as much as possible.
Some programs that I've noticed seem to kill my battery faster even when not using the particular app:
- Words with Friends
- Winamp
- Task Killers
- Trillian
- Samba Filesharing (only when sharing is active though)
- Google Latitude (although battery drain on this service is much less than in it used to be in the past)
- Wifi Protector
I'm sure there are a few others I'll think of later..

yep 4g destroys battery. im working on making a task for tasker app that will turn on the ICS power save mode when screen is off.
the power save mode will kick in normally when the phone is below 20% i believe. but the options you have for said mode, you can turn off 4g and turn 1 core off. but this task is hard to do because i am no way a dev.
I personally find that awake battery life is decent, screen of battery is less than decent.
newest leak seems to be, awake (screen on) battery is terrible, screen off battery drain is nonexsistant ~ unless you are asking for it by having gps, autosync, or 4g on
One thing, I pay 30 bucks a month for data (just like the rest of you) and have a hard time sucking on WiFi because of poor battery life. I guess my point is why have 4G if you can't use it? If thats the case I might as well of stayed with Sprint. That said I think the 4G drain would really depend on how far the tower is from your location. Mine are pretty close. I have gone the other route and turned off WiFi and just live off 4G. I'll let you know how that goes..
I actually got rid of my extended battery and went back to my stock one after I flashed the newest leak. It's that much better. I also use 4g all the time, no WiFi

I am on latest leak and battery life is decent with extended. Agree that with screen off battery drain is very slow. Battery even charges quickly even while tethering. It could always be better though.. with heavy use I can drain by battery in a 3 to 4 hours. And heavy is reading forums and articles using tapatalk 2, tweetdeck for twitter/fb, ESPN score center, maybe you tube but just the screen on and typing/touching the screen kills it.
Using leaked 3.14.605.. s-off and..

I think it matters a great deal how strong your signal is. I only have 3G in my area and my signal at home is pretty weak. When I turn off wifi and just use 3G my battery drops like a rock.

The screen-on time is the main battery killer of the device.
I agree that overall the battery life on the Rezound has been relatively poor for me in comparison to other smartphones - regardless of what kernel I have been running.
Holding out hope that the upcoming official ICS release helps. Aside from that, I just placed an order for the beastly extended battery.
I like this device, but the battery life is just not very good.
The screen is the number one killer (since it's high-def) followed by the 4G radio. After a normal day's usage my screen takes up anywhere from 75%+ of the battery life.

They have this already. It's juice defender. Well not the core part but it does turn off 4g and wifi too.

I have 7 extended Batts and don't think bad batteries is the problem. Phones just sucks battery when screen on unless you turn the brightness all the way down. Would rather swap batteries every 12 hours than dim the screen to the point of not being able to see it...

U should look at my post in the battery stats thread. I get pretty good battery life, pretty always have with android phones.
I guess I just have to stop streaming my fav show in the morning Bababooey.
Hopefully with the ICS release our devs can do something about this.

it's mostly the kernel. can't manage frequency or governors without tampering perflock. can't undervolt. once we have a fully controllable devicevwe can save more power. just don't have too high expectations because I seriously doubt we can get double the juice with how much the display drains

[TIP] Better battery life

One thing I found to save power that I don't really see posted anywhere is by using this app: https://play.google.com/store/apps/details?id=AutomateItPro.mainPackage&feature=more_from_developer#?t=W251bGwsMSwyLDEwMiwiQXV0b21hdGVJdFByby5tYWluUGFja2FnZSJd
I have it programed to turn off 3G/mobile data when it screen's off....unless I have a certain app running like say the browser. It will then keep data connected until the browser is closed, then the screen turned off. I then have it turn 3G/mobile data on as soon as I screen on again, so it's ready to rock instantly. I personally noticed a huge difference in my battery drain when not using the phone.
The app is pretty cool, you can program a ton of things. I have gps auto turn on when I use G-Maps or GasBuddy, then it auto turns off when I close those apps. Saves time and juice imo. Just figured I'd throw this out there.
nice app. isn't there a setting within the OS to do this, though? pretty sure there is.
either way, agreed. data usage can/will cause battery drain.
the real perp is your display, however. adjust your brightness settings, you will see significant battery improvements.
My display is set low, and all my other settings are set to be battery friendly. It's been awhile since I used the app. But after I had that setup, I noticed better life instantly. Went fishing today with the little guy, left the house with 100%. No phone usage for 2hrs, and it was still at 99%.
Can't you do this without the app tho

If there's a way to set the phone to turn the radio off when screen is off, I'm unaware of that. I tried turning it on and off manually, but it got to be a pain turning it on and off all the time. I would end up just leaving it on. Now I don't even have to think about it, and it gets done everytime.
Sounds similar to Tasker, which is a little confusing to new users.
But as for your post, turning 3g off saves a TON of battery. I have to keep it on during the day to get emails for my job, but at night, I turn 3g off, and the phone will drop maybe 2% overnight with 3g off.
The CDMA version of the 3D has a setting in network that allows you to turn off your mobile network if the screen is off for 5+ minutes. The setting is "turn off always on mobile network". But the screens needs to be off 5 minutes before it will. This setting will not turn off wifi though.

Pix or it didn't happen. I have full bars with 4G and my battery drains a lot faster.

If you wanted to save battery life without downloading anything you could just use the HTC widgets for mobile network, 4g, WiFi, and GPS. This method allows me to switch the settings on and off on the fly. I've also found that if you disable all GPS options it won't be running in the background and for apps that require it. And if I'm in one spot for a while I just use WiFi.
